1 # NEWS for rsync 3.2.5 (UNRELEASED)
3 ## Changes in this version:
7 - Added some file-list safety checking that helps to ensure that a rogue
8 sending rsync can't add unrequested top-level names and/or include recursive
9 names that should have been excluded by the sender. These extra safety
10 checks only require the receiver rsync to be udateed. When dealing with an
11 untrusted sending host, it is safest to copy into a dedicated destination
12 directory for the remote content (i.e. don't copy into a destination
13 directory that contains files that aren't from the remote host unless you
14 trust the remote host). Fixes CVE-2022-29154.
18 - Fixed the configure check for signed char that was causing a host that
19 defaults to unsigned characters to generate bogus rolling checksums. This
20 made rsync send mostly literal data for a copy instead of finding matching
21 data in the receiver's basis file.
23 - Lots of manpage improvements, including an attempt to better desdribe how
24 include/exclude filters work.
26 ### PACKAGING RELATED:
28 - The build date that goes into the manpages is now based on the developer's
29 release date, not on the build's local-timezone interpretation of the date.
31 ### DEVELOPER RELATED:
33 - Configure now defaults GETGROUPS_T to gid_t when cross compiling.
35 - Configure now looks for the bsd/string.h include file in order to fix the
36 build on a host that has strlcpy() in the main libc but not defined in the

41 # NEWS for rsync 3.2.4 (15 Apr 2022)
43 ## Changes in this version:
47 - A new form of arg protection was added that works similarly to the older
48 [`--protect-args`](rsync.1#opt) (`-s`) option but in a way that avoids
49 breaking things like rrsync (the restricted rsync script): rsync now uses
50 backslash escaping for sending "shell-active" characters to the remote
51 shell. This includes spaces, so fetching a remote file via a simple quoted
52 filename value now works by default without any extra quoting:
55 rsync -aiv host:'a simple file.pdf' .
58 Wildcards are not escaped in filename args, but they are escaped in options
59 like the [`--suffix`](rsync.1#opt) and [`--usermap`](rsync.1#opt) values.
60 If your rsync script depends on the old arg-splitting behavior, either run
61 it with the [`--old-args`](rsync.1#opt) option or `export RSYNC_OLD_ARGS=1`
62 in the script's environment. See also the [ADVANCED USAGE](rsync.1#)
63 section of rsync's manpage for how to use a more modern arg style.
65 - A long-standing bug was preventing rsync from figuring out the current
66 locale's decimal point character, which made rsync always output numbers
67 using the "C" locale. Since this is now fixed in 3.2.4, a script that
68 parses rsync's decimal numbers (e.g. from the verbose footer) may want to
69 setup the environment in a way that the output continues to be in the C
70 locale. For instance, one of the following should work fine:
76 or if iconv translations are needed:
79 if [ "${LC_ALL:-}" ]; then
81 export LC_CTYPE="$LC_ALL"
84 export LC_NUMERIC=C.UTF-8
89 - A fix for CVE-2018-25032 in the bundled zlib (memory corruption issue).
93 - Fixed a bug with [`--inplace`](rsync.1#opt) + [`--sparse`](rsync.1#opt) (and
94 a lack of [`--whole-file`](rsync.1#opt)) where the destination file could
95 get reconstructed with bogus data. Since the bug can also be avoided by
96 using (the seemingly redundant) [`--no-W`](rsync.1#opt) on the receiving
97 side, the latest rsync will now send `--no-W` to a remote receiver when this
98 option combination occurs. If your client rsync is not new enough to do
99 this for you (or if you're just paranoid), you can manually specify `--no-W
100 -M--no-W` (when not using [`--whole-file`](rsync.1#opt)) to make sure the
103 - Fixed a bug with [`--mkpath`](rsync.1#opt) if a single-file copy specifies
104 an existing destination dir with a non-existing destination filename.
106 - Fixed `--update -vv` to output "is uptodate" instead of "is newer" messages
107 for files that are being skipped due to an identical modify time. (This was
108 a new output quirk in 3.2.3.)
110 - When doing an append transfer, the sending side's file must not get shorter
111 or it is skipped. Fixes a crash that could occur when the size changes to 0
112 in the middle of the send negotiations.
114 - When dealing with special files (see [`--specials`](rsync.1#opt)) in an
115 alt-dest hierarchy, rsync now checks the non-permission mode bits to ensure
116 that the 2 special files are really the same before hard-linking them
119 - Fixed a bug where [`--delay-updates`](rsync.1#opt) with stale partial data
120 could cause a file to fail to update.
122 - Fixed a few places that would output an INFO message with
123 [`--info=NAME`](rsync.1#opt) that should only have been output given
124 [`--verbose`](rsync.1#opt) or [`--itemize-changes`](rsync.1#opt).
126 - Avoid a weird failure if you run a local copy with a (useless)
127 [`--rsh`](rsync.1#opt) option that contains a `V` in the command.
129 - Fixed a long-standing compression bug where the compression level of the
130 first file transferred affected the level for all future files. Also, the
131 per-file compression skipping has apparently never worked, so it is now
132 documented as being ineffective.
134 - Fixed a truncate error when a `--write-devices` copy wrote a file onto a
135 device that was shorter than the device.
137 - Made `--write-devices` support both `--checksum` and `--no-whole-file` when
140 - Improved how the [`--stop-at`](rsync.1#opt), [`--stop-after`](rsync.1#opt),
141 and (the deprecated) [`--time-limit`](rsync.1#opt) options check to see if
142 the allowed time is over, which should make rsync exit more consistently.
144 - Tweak --progress to display "`??:??:??`" when the time-remaining value is so
145 large as to be meaningless.
147 - Silence some chmod warnings about symlinks when it looks like we have a
148 function to set their permissions but they can't really be set.
150 - Fixed a potential issue in git-set-file-times when handling commits with
151 high-bit characters in the description & when handling a description that
152 might mimick the git raw-commit deliniators. (See the support dir.)
154 - The bundled systemd/rsync.service file now includes `Restart=on-failure`.
158 - Use openssl's `-verify_hostname` option in the rsync-ssl script.
160 - Added extra info to the "FILENAME exists" output of
161 [`--ignore-existing`](rsync.1#opt) when [`--info=skip2`](rsync.1#opt) is
162 used. The skip message becomes "FILENAME exists (INFO)" where the INFO is
163 one of "type change", "sum change" (requires [`--checksum`](rsync.1#opt)),
164 "file change" (based on the quick check), "attr change", or "uptodate".
165 Prior versions only supported `--info=skip1`.
167 - Added the [`--fsync`](rsync.1#opt) option (promoted from the patches repo).
169 - Added the [`--copy-devices`](rsync.1#opt) option. Compared to the
170 historical version from the rsync-patches repo, this version: properly
171 handles `--checksum`; fixes a truncation bug when doing an `--inplace` copy
172 onto a longer file; fixes several bugs in the `--itemize` output; and only
173 the sending side needs the enhanced rsync for the copy to work.
175 - Reduced memory usage for an incremental transfer that has a bunch of small
178 - The rsync daemon can now handle a client address with an implied "%scope"
181 - Added support for [`--atimes`](rsync.1#opt) on macOS and fixed a bug where
182 it wouldn't work without [`--times`](rsync.1#opt).
184 - Rsync can now update the xattrs on a read-only file when your user can
185 temporarily add user-write permission to the file. (It always worked for a
188 - Rsync can now work around an [`--inplace`](rsync.1#opt) update of a file
189 that is being refused due to the Linux fs.protected_regular sysctl setting.
191 - When [`--chown`](rsync.1#opt), [`--usermap`](rsync.1#opt), or
192 [`--groupmap`](rsync.1#opt) is specified, rsync now makes sure that the
193 appropriate [`--owner`](rsync.1#opt) and/or [`--group`](rsync.1#opt) options
196 - Added the [`--info=NONREG`](rsync.1#opt) setting to control if rsync should
197 warn about non-regular files in the transfer. This is enabled by default
198 (keeping the behavior the same as before), so specifying `--info=nonreg0`
199 can be used to turn the warnings off.
201 - An optional asm optimization for the rolling checksum from Shark64. Enable
202 it with `./configure --enable-roll-asm`.
204 - Using `--debug=FILTER` now outputs a caution message if a filter rule
205 has trailing whitespace.
207 - Transformed rrsync into a python script with improvements:
208 - Security has been beefed up.
209 - The known rsync options were updated to include recent additions.
210 - Make rrsync reject [`--copy-links`](rsync.1#opt) (`-L`),
211 [`--copy-dirlinks`](rsync.1#opt) (`-k`), &
212 [`--keep-dirlinks`](rsync.1#opt) (`-K`) by default to make it harder to
213 exploit any out-of-subdir symlinks.
214 - A new rrsync option of [`-munge`](rrsync.1#opt) tells rrsync to always
215 enable rsync's [`--munge-links`](rsync.1#opt) option on the server side.
216 - A new rrsync option of [`-no-lock`](rrsync.1#opt) disables a new
217 single-use locking idiom that is the default when [`-ro`](rrsync.1#opt) is
218 not used (useful with [`-munge`](rrsync.1#opt)).
219 - A new rrsync option of [`-no-del`](rrsync.1#opt) disables all `--remove*`
220 and `--delete*` rsync options on the server side.
221 - The log format has been tweaked slightly to add seconds to the timestamp
222 and to output the command executed as a tuple (making the args clearer).
223 - An rrsync.1 manpage was added (in the support dir with rrsync).
225 - Added options to the lsh script to facilitate rrsync testing. (See the
228 - Transformed the atomic-rsync script into a python script and added the
229 ability to ignore one or more non-zero exit codes. By default, it now
230 ignores code 24, the file-vanished exit code. (See the support dir.)
232 - Transformed the munge-symlinks script into python. (See the support dir.)
234 - Improved the rsync-no-vanished script to not join stdout & stderr together.
235 (See the support dir.)
237 - Work around a glibc bug where lchmod() breaks in a chroot w/o /proc mounted.
239 - Try to support a client that sent a remote rsync a wacko stderr file handle
240 (such as an older File::RsyncP perl library used by BackupPC).
242 - Lots of manpage improvements, including better HTML versions.
244 ### PACKAGING RELATED:
246 - Give configure the `--with-rrsync` option if you want `make install` to
247 install the (now python3) rrsync script and its new manpage.
249 - If the rrsync script is installed, its package should be changed to depend
250 on python3 and the (suggested but not mandatory) python3 braceexpand lib.
252 - When creating a package from a non-release version (w/o a git checkout), the
253 packager can elect to create git-version.h and define RSYNC_GITVER to the
254 string they want `--version` to output. (The file is still auto-generated
255 using the output of `git describe` when building inside a non-shallow git
258 - Renamed configure's `--enable-simd` option to `--enable-roll-simd` and added
259 the option `--enable-roll-asm` to use the new asm version of the code. Both
260 are x86_64/amd64 only.
262 - Renamed configure's `--enable-asm` option to `--enable-md5-asm` to avoid
263 confusion with the asm option for the rolling checksum. It is also honored
264 even when openssl crypto is in use. This allows: normal MD4 & MD5, normal
265 MD4 + asm MD5, openssl MD4 & MD5, or openssl MD4 + asm MD5 depending on the
266 configure options selected.
268 - Made SIMD & asm configure checks default to "no" on non-Linux hosts due to
269 various reports of problems on NetBSD & macOS hosts. These were also
270 tweaked to allow enabling the feature on a host_cpu of amd64 (was only
271 allowed on x86_64 before).
273 - Fixed configure to not fail at the SIMD check when cross-compiling.
275 - Improved the IPv6 determination in configure.
277 - Compile the C files with `-pedantic-errors` (when possible) so that we will
278 get warned if a static initialization overflows in the future (among other
281 - When linking with an external zlib, rsync renames its `read_buf()` function
282 to `read_buf_()` to avoid a symbol clash on an unpatched zlib.
284 - Added a SECURITY.md file.
286 ### DEVELOPER RELATED:
288 - Made it easier to write rsync tests that diff the output while also checking
289 the status code, and used the idiom to improve the existing tests. (See the
290 `checkdiff` and `checkdiff2` idioms in the `testsuite/*.test` files.
292 - The packaging scripts & related python lib got some minor enhancements.
296 - Use setenv() instead of putenv() when it is available.
298 - Improve the logic in compat.c so that we don't need to try to remember to
299 sprinkle `!local_server` exceptions throughout the protocol logic.
301 - One more C99 Flexible Array improvement (started in the last release) and
302 make use of the C99 `%zd` format string when printing size_t values (when
305 - Use mallinfo2() instead of mallinfo(), when available.
307 ------------------------------------------------------------------------------
309 # NEWS for rsync 3.2.3 (6 Aug 2020)
311 ## Changes in this version:
315 - Fixed a bug in the xattr code that was freeing the wrong object when trying
316 to cleanup the xattr list.
318 - Fixed a bug in the xattr code that was not leaving room for the "rsync."
319 prefix in some instances where it needed to be added.
321 - Restored the ability to use [`--bwlimit=0`](rsync.1#opt) to specify no
322 bandwidth limit. (It was accidentally broken in 3.2.2.)
324 - Fixed a bug when combining [`--delete-missing-args`](rsync.1#opt) with
325 [`--no-implied-dirs`](rsync.1#opt) & [`-R`](rsync.1#opt) where rsync might
326 create the destination path of a missing arg. The code also avoids some
327 superfluous warnings for nested paths of removed args.
329 - Fixed an issue where hard-linked devices could cause the rdev_major value to
330 get out of sync between the sender and the receiver, which could cause a
331 device to get created with the wrong major value in its major,minor pair.
333 - Rsync now complains about a missing [`--temp-dir`](rsync.1#opt) before
334 starting any file transfers.
336 - A completely empty source arg is now a fatal error. This doesn't change
337 the handling of implied dot-dir args such as "localhost:" and such.
341 - Allow [`--max-alloc=0`](rsync.1#opt) to specify no limit to the alloc sanity
344 - Allow [`--block-size=SIZE`](rsync.1#opt) to specify the size using units
347 - The name of the id-0 user & group are now sent to the receiver along with
348 the other user/group names in the transfer (instead of assuming that both
349 sides have the same id-0 names).
351 - Added the [`--stop-after`](rsync.1#opt) and [`--stop-at`](rsync.1#opt)
352 options (with a [`--time-limit`](rsync.1#opt) alias for `--stop-after`).
353 This is an enhanced version of the time-limit patch from the patches repo.
355 - Added the [`name converter`](rsyncd.conf.5#opt) daemon parameter to make it
356 easier to convert user & group names inside a chrooted daemon module. This
357 is based on the nameconverter patch with some improvements, including a
358 tweak to the request protocol (so if you used this patch in the past, be
359 sure to update your converter script to use newlines instead of null chars).
361 - Added [`--crtimes`](rsync.1#opt) (`-N`) option for preserving the file's
362 create time (I believe that this is macOS only at the moment).
364 - Added [`--mkpath`](rsync.1#opt) option to tell rsync that it should create a
365 non-existing path component of the destination arg.
367 - Added [`--stderr=errors|all|client`](rsync.1#opt) to replace the
368 `--msgs2stderr` and `--no-msgs2stderr` options (which are still accepted).
369 The default use of stderr was changed to be `--stderr=errors` where all the
370 processes that have stderr available output directly to stderr, which should
371 help error messages get to the user more quickly, especially when doing a
372 push (which includes local copying). This also allows rsync to exit quickly
373 when a receiver failure occurs, since rsync doesn't need to try to keep the
374 connection alive long enough for the fatal error to go from the receiver to
375 the generator to the sender. The old default can be requested via
376 `--stderr=client`. Also changed is that a non-default stderr mode is
377 conveyed to the remote rsync (using the older option names) instead of
378 requiring the user to use [`--remote-option`](rsync.1#opt) (`-M`) to tell
379 the remote rsync what to do.
381 - Added the ability to specify "@netgroup" names to the [`hosts
382 allow`](rsyncd.conf.5#opt) and [`hosts deny`](rsyncd.conf.5#opt) daemon
383 parameters. This is a finalized version of the netgroup-auth patch from the
386 - Rsync can now hard-link symlinks on FreeBSD due to it making use of the
387 linkat() function when it is available.
389 - Output file+line info on out-of-memory & overflow errors while also avoiding
390 the output of alternate build-dir path info that is not useful to the user.
392 - Change configure to know that Cygwin supports Linux xattrs.
394 - Improved the testsuite on FreeBSD & Cygwin.
396 - Added some compatibility code for HPE NonStop platforms.
398 - Improved the INSTALL.md info.
400 - Added a few more suffixes to the default skip-compress list.
402 - Improved configure's error handling to notify about several issues at once
403 instead of one by one (for the newest optional features).
407 - Use a simpler overflow check idiom in a few spots.
409 - Use a C99 Flexible Array for a trailing variable-size filename in a struct
410 (with a fallback to the old 1-char string kluge for older compilers).
412 ------------------------------------------------------------------------------
414 # NEWS for rsync 3.2.2 (4 Jul 2020)
416 ## Changes in this version:
420 - Avoid a crash when a daemon module enables `transfer logging` without
421 setting a `log format` value.
423 - Fixed installing rsync-ssl script from an alternate build dir.
425 - Fixed the updating of configure.sh from an alternate build dir.
427 - Apple requires the asm function name to begin with an underscore.
429 - Avoid a test failure in the daemon test when `--atimes` is disabled.
433 - Allow the server side to restrict checksum & compression choices via the
434 same environment variables the client uses. The env vars can be divided
435 into "client list & server list" by the "`&`" char or the same list can
438 - Simplify how the negotiation environment variables apply when interacting
439 with an older rsync and also when a list contains only invalid names.
441 - Do not allow a negotiated checksum or compression choice of "none" unless
442 the user authorized it via an environment variable or command-line option.
444 - Added the `--max-alloc=SIZE` option to be able to override the memory
445 allocator's sanity-check limit. It defaults to 1G (as before) but the error
446 message when exceeding it specifically mentions the new option so that you
447 can differentiate an out-of-memory error from a failure of this limit. It
448 also allows you to specify the value via the RSYNC_MAX_ALLOC environment
451 - Add the "open atime" daemon parameter to allow a daemon to always enable or
452 disable the use of O_NOATIME (the default is to let the user control it).
454 - The default systemd config was changed to remove the `ProtectHome=on`
455 setting since rsync is often used to serve files in /home and /root and this
456 seemed a bit too strict. Feel free to use `systemctl edit rsync` to add
457 that restriction (or maybe `ProtectHome=read-only`), if you like. See the
458 3.2.0 NEWS for the other restrictions that were added compared to 3.1.3.
460 - The memory allocation functions now automatically check for a failure and
461 die when out of memory. This eliminated some caller-side check-and-die
462 code and added some missing sanity-checking of allocations.
464 - Put optimizations into their own list in the `--version` output.
466 - Improved the manpage a bit more.
468 ### PACKAGING RELATED:
470 - Prepared the checksum code for an upcoming xxHash release that provides new
471 XXH3 (64-bit) & XXH128 (128-bit) checksum routines. These will not be
472 compiled into rsync until the xxhash v0.8.0 include files are installed on
473 the build host, and that release is a few weeks away at the time this was
474 written. So, if it's now the future and you have packaged and installed
475 xxhash-0.8.0-devel, a fresh rebuild of rsync 3.2.2 will give you the new
476 checksum routines. Just make sure that the new rsync package depends on
479 ### DEVELOPER RELATED:
481 - Moved the version number out of configure.ac into its own version.h file so
482 that we don't need to reconfigure just because the version number changes.
484 - Moved the daemon parameter list into daemon-parm.txt so that an awk script
485 can create the interrelated structs and accessors that loadparm.c needs.
487 ------------------------------------------------------------------------------
489 # NEWS for rsync 3.2.1 (22 Jun 2020)
491 ## Changes in this version:
495 - Fixed a potential build issue with the MD5 assembly-language code by
496 removing some non-portable directives.
498 - Use the preprocessor with the asm file to ensure that if the code is
499 unneeded, it doesn't get built.
501 - Avoid the stack getting set to executable when including the asm code.
503 - Some improvements in the SIMD configure testing to try to avoid build
504 issues, such as avoiding a clang++ core dump when `-g` is combined with
505 `-O2`. Note that clang++ is quite buggy in this area, and it does still
506 crash for some folks, so just use `--disable-simd` if you need to avoid
507 their buggy compiler (since the configure test is apparently not finding
508 all the compilers that will to crash and burn).
510 - Fixed an issue in the md2man script when building from an alternate dir.
512 - Disable `--atimes` on macOS (it apparently just ignores the atime change).
516 - The use of `--backup-dir=STR` now implies `--backup`.
518 - Added `--zl=NUM` as a short-hand for `--compress-level=NUM`.
520 - Added `--early-input=FILE` option that allows the client to send some
521 data to a daemon's (optional) "early exec" script on its stdin.
523 - Mention atimes in the capabilities list that `--version` outputs.
525 - Mention either "default protect-args" or "optional protect-args" in the
526 `--version` capabilities depending on how rsync was configured.
528 - Some info on optimizations is now elided from the `--version` capabilities
529 since they aren't really user-facing capabilities. You can still see the
530 info (plus the status of a couple extra optimizations) by repeating the
531 `--version` option (e.g. `-VV`).
533 - Updated various URLs to be https instead of http.
535 - Some documentation improvements.
537 ### PACKAGING RELATED:
539 - If you had to use `--disable-simd` for 3.2.0, you might want to try removing
540 that and see if it will succeed or auto-disable. Some buggy clang++
541 compilers are still not auto disabled, though.
543 - The MD5 asm code is now under its own configure flag (not shared with the
544 SIMD setting), so if you have any issues compiling it, re-run configure with
547 - Merged the OLDNEWS.md file into NEWS.md.
549 ------------------------------------------------------------------------------
551 # NEWS for rsync 3.2.0 (19 Jun 2020)
553 ## Changes in this version:
557 - Avoid a potential out-of-bounds read in daemon mode if argc can be made to
560 - Fix the default list of skip-compress files for non-daemon transfers.
562 - Fix xattr filter rules losing an 'x' attribute in a non-local transfer.
564 - Avoid an error when a check for a potential fuzzy file happens to reference
567 - Make the atomic-rsync helper script have a more consistent error-exit.
569 - Make sure that a signal handler's use of exit_cleanup() calls `_exit()`
572 - Various zlib fixes, including security fixes for CVE-2016-9843,
573 CVE-2016-9842, CVE-2016-9841, and CVE-2016-9840.
575 - Fixed an issue with `--remove-source-files` not removing a source symlink
576 when combined with `--copy-links`.
578 - Fixed a bug where the daemon would fail to write early fatal error messages
579 to the client, such as refused or unknown command-line options.
581 - Fixed the block-size validation logic when dealing with older protocols.
583 - Some rrsync fixes and enhancements to handle the latest options.
585 - Fixed a problem with the `--link-dest`|`--copy-dest` code when `--xattrs`
586 was specified along with multiple alternate-destination directories (it
587 could possibly choose a bad file match while trying to find a better xattr
590 - Fixed a couple bugs in the handling of files with the `--sparse` option.
592 - Fixed a bug in the writing of the batch.sh file (w/`--write-batch`) when the
593 source & destination args were not last on the command-line.
595 - Avoid a hang when an overabundance of messages clogs up all the I/O buffers.
597 - Fixed a mismatch in the RSYNC_PID values put into the environment of
598 `pre-xfer exec` and a `post-xfer exec`.
600 - Fixed a crash in the `--iconv` code.
602 - Fixed a rare crash in the popt_unalias() code.
606 - The default systemd config was made stricter by default. For instance,
607 `ProtectHome=on` (which hides content in /root and /home/USER dirs),
608 `ProtectSystem=full` (which makes /usr, /boot, & /etc dirs read-only), and
609 `PrivateDevices=on` (which hides devices). You can override any of these
610 using the standard `systemctl edit rsync` and add one or more directives
611 under a `[Service]` heading (and restart the rsync service).
613 - Various checksum enhancements, including the optional use of openssl's MD4 &
614 MD5 checksum algorithms, some x86-64 optimizations for the rolling checksum,
615 some x86-64 optimizations for the (non-openssl) MD5 checksum, the addition
616 of xxHash checksum support, and a negotiation heuristic that ensures that it
617 is easier to add new checksum algorithms in the future. The environment
618 variable `RSYNC_CHECKSUM_LIST` can be used to customize the preference order
619 of the negotiation, or use `--checksum-choice` (`--cc`) to force a choice.
621 - Various compression enhancements, including the addition of zstd and lz4
622 compression algorithms and a negotiation heuristic that picks the best
623 compression option supported by both sides. The environment variable
624 `RSYNC_COMPRESS_LIST` can be used to customize the preference order of the
625 negotiation, or use `--compress-choice` (`--zc`) to force a choice.
627 - Added a `--debug=NSTR` option that outputs details of the new negotiation
628 strings (for checksums and compression). The first level just outputs the
629 result of each negotiation on the client, level 2 outputs the values of the
630 strings that were sent to and received from the server, and level 3 outputs
631 all those values on the server side too (when the server was given the debug
634 - The `--debug=OPTS` command-line option is no longer auto-forwarded to the
635 remote rsync which allows for the client and server to have different levels
636 of debug specified. This also allows for newer debug options to be
637 specified, such as using `--debug=NSTR` to see the negotiated hash result,
638 without having the command fail if the server version is too old to handle
639 that debug item. Use `-M--debug=OPTS` to send the options to the remote side.
641 - Added the `--atimes` option based on the long-standing patch (just with some
642 fixes that the patch has been needing).
644 - Added `--open-noatime` option to open files using `O_NOATIME`.
646 - Added the `--write-devices` option based on the long-standing patch.
648 - Added openssl & preliminary gnutls support to the rsync-ssl script, which is
649 now installed by default. This was unified with the old stunnel-rsync
650 helper script to simplify packaging. Note that the script accepts the use
651 of `--type=gnutls` for gnutls testing, but does not look for gnutls-cli on
652 the path yet. The use of `--type=gnutls` will not work right until
653 gnutls-cli no longer drops data.
655 - Rsync was enhanced to set the `RSYNC_PORT` environment variable when running
656 a daemon-over-rsh script. Its value is the user-specified port number (set
657 via `--port` or an rsync:// URL) or 0 if the user didn't override the port.
659 - Added the `proxy protocol` daemon parameter that allows your rsyncd to know
660 the real remote IP when it is setup behind a proxy.
662 - Added negated matching to the daemon's `refuse options` setting by using
663 match strings that start with a `!` (such as `!compress*`). This lets you
664 refuse all options except for a particular approved list, for example. It
665 also lets rsync refuse certain options by default (such as `write-devices`)
666 while allowing the config to override that, as desired.
668 - Added the `early exec` daemon parameter that runs a script before the
669 transfer parameters are known, allowing some early setup based on module
672 - Added status output in response to a signal (via both SIGINFO & SIGVTALRM).
674 - Added `--copy-as=USER` option to give some extra security to root-run rsync
675 commands into/from untrusted directories (such as backups and restores).
677 - When resuming the transfer of a file in the `--partial-dir`, rsync will now
678 update that partial file in-place instead of creating yet another tmp file
679 copy. This requires both sender & receiver to be at least v3.2.0.
681 - Added support for `RSYNC_SHELL` & `RSYNC_NO_XFER_EXEC` environment variables
682 that affect the early, pre-xfer, and post-xfer exec rsync daemon parameters.
684 - Optimize the `--fuzzy --fuzzy` heuristic to avoid the fuzzy directory scan
685 until all other basis-file options are exhausted (such as `--link-dest`).
687 - Have the daemon log include the normal-exit sent/received stats when the
688 transfer exited with an error when possible (i.e. if it is the sender).
690 - The daemon now locks its pid file (when configured to use one) so that it
691 will not fail to start when the file exists but no daemon is running.
693 - Various manpage improvements, including some html representations (that
694 aren't installed by default).
696 - Made `-V` the short option for `--version` and improved its information.
698 - Pass the `-4` or `-6` option to the ssh command, making it easier to type
699 than `--rsh='ssh -4'` (or the `-6` equivalent).
701 - Added example config for rsyncd SSL proxy configs to rsyncd.conf.
703 - More errors messages now mention if the error is coming from the sender or
706 ### PACKAGING RELATED:
708 - Add installed bash script: /usr/bin/rsync-ssl
710 - Add installed manpage: /usr/man/man1/rsync-ssl.1
712 - Tweak auxiliary doc file names, such as: README.md, INSTALL.md, & NEWS.md.
714 - The rsync-ssl script wants to run openssl or stunnel4, so consider adding a
715 dependency for one of those options (though it's probably fine to just let
716 it complain about being unable to find the program and let the user decide
717 if they want to install one or the other).
719 - If you packaged rsync + rsync-ssl + rsync-ssl-daemon as separate packages,
720 the rsync-ssl package is now gone (rsync-ssl should be considered to be
721 mainstream now that Samba requires SSL for its rsync daemon).
723 - Add _build_ dependency for liblz4-dev, libxxhash-dev, libzstd-dev, and
724 libssl-dev. These development libraries will give rsync extra compression
725 algorithms, extra checksum algorithms, and allow use of openssl's crypto
726 lib for (potentially) faster MD4/MD5 checksums.
728 - Add _build_ dependency for g++ or clang++ on x86_64 systems to enable the
729 SIMD checksum optimizations.
731 - Add _build_ dependency for _either_ python3-cmarkcfm or python3-commonmark
732 to allow for patching of manpages or building a git release. This is not
733 required for a release-tar build, since it comes with pre-built manpages.
734 Note that cmarkcfm is faster than commonmark, but they generate the same
735 data. The commonmark dependency is easiest to install since it's native
736 python, and can even be installed via `pip3 install --user commonmark` if
737 you want to just install it for the build user.
739 - Remove yodl _build_ dependency (if it was even listed before).
741 ### DEVELOPER RELATED:
743 - Silenced some annoying warnings about major() & minor() by improving an
744 autoconf include-file check.
746 - Converted the manpages from yodl to markdown. They are now processed via a
747 simple python3 script using the cmarkgfm **or** commonmark library. This
748 should make it easier to package rsync, since yodl is rather obscure.
750 - Improved some configure checks to work better with strict C99 compilers.
752 - Some perl building/packaging scripts were recoded into awk and python3.
754 - Some defines in byteorder.h were changed into static inline functions that
755 will help to ensure that the args don't get evaluated multiple times on
756 "careful alignment" hosts.
758 - Some code typos were fixed (as pointed out by a Fossies run).
760 ------------------------------------------------------------------------------
762 # NEWS for rsync 3.1.3 (28 Jan 2018)
764 ## Changes in this version:
768 - Fixed a buffer overrun in the protocol's handling of xattr names and ensure
769 that the received name is null terminated.
771 - Fix an issue with `--protect-args` where the user could specify the arg in the
772 protected-arg list and short-circuit some of the arg-sanitizing code.
776 - Don't output about a new backup dir without appropriate info verbosity.
778 - Fixed some issues with the sort functions in the rsyncstats script (in the
781 - Added a way to specify daemon config lists (e.g. users, groups, etc) that
782 contain spaces (see `auth users` in the latest rsyncd.conf manpage).
784 - If a backup fails (e.g. full disk) rsync exits with an error.
786 - Fixed a problem with a doubled `--fuzzy` option combined with `--link-dest`.
788 - Avoid invalid output in the summary if either the start or end time had an
791 - We don't allow a popt alias to affect the `--daemon` or `--server` options.
793 - Fix daemon exclude code to disallow attribute changes in addition to
794 disallowing transfers.
796 - Don't force nanoseconds to match if a non-transferred, non-checksummed file
797 only passed the quick-check w/o comparing nanoseconds.
801 - Added the ability for rsync to compare nanosecond times in its file-check
802 comparisons, and added support nanosecond times on Mac OS X.
804 - Added a short-option (`-@`) for `--modify-window`.
806 - Added the `--checksum-choice=NAME[,NAME]` option to choose the checksum
809 - Added hashing of xattr names (with using `-X`) to improve the handling of
810 files with large numbers of xattrs.
812 - Added a way to filter xattr names using include/exclude/filter rules (see
813 the `--xattrs` option in the manpage for details).
815 - Added `daemon chroot|uid|gid` to the daemon config (in addition to the old
816 chroot|uid|gid settings that affect the daemon's transfer process).
818 - Added `syslog tag` to the daemon configuration.
820 - Some manpage improvements.
822 ### DEVELOPER RELATED:
824 - Tweak the `make` output when yodl isn't around to create the manpages.
826 - Changed an obsolete autoconf compile macro.
828 - Support newer yodl versions when converting manpages.
830 ------------------------------------------------------------------------------
832 # NEWS for rsync 3.1.2 (21 Dec 2015)
834 ## Changes in this version:
838 - Make sure that all transferred files use only path names from inside the
839 transfer. This makes it impossible for a malicious sender to try to make the
840 receiver use an unsafe destination path for a transferred file, such as a
845 - Change the checksum seed order in the per-block checksums. This prevents
846 someone from trying to create checksum blocks that match in sum but not
849 - Fixed a with the per-dir filter files (using `-FF`) that could trigger an
852 - Only skip `set_modtime()` on a transferred file if the time is exactly
855 - Don't create an empty backup dir for a transferred file that doesn't exist
858 - Fixed a bug where `--link-dest` and `--xattrs` could cause rsync to exit if
859 a filename had a matching dir of the same name in the alt-dest area.
861 - Allow more than 32 group IDs per user in the daemon's gid=LIST config.
863 - Fix the logging of %b & %c via `--log-file` (daemon logging was already
864 correct, as was `--out-format='%b/%c'`).
866 - Fix erroneous acceptance of `--info=5` & `--debug=5` (an empty flag name is
871 - Added `(DRY RUN)` info to the `--debug=exit` output line.
873 - Use usleep() for our msleep() function if it is available.
875 - Added a few extra long-option names to rrsync script, which will make
878 - Made configure choose to use Linux xattrs on NetBSD (rather than not
881 - Added `-wo` (write-only) option to rrsync support script.
883 - Misc. manpage tweaks.
885 ### DEVELOPER RELATED:
887 - Fixed a bug with the Makefile's use of `INSTALL_STRIP`.
889 - Improve a test in the suite that could get an erroneous timestamp error.
891 - Tweaks for newer versions of git in the packaging tools.
893 - Improved the m4 generation rules and some autoconf idioms.
895 ------------------------------------------------------------------------------
897 # NEWS for rsync 3.1.1 (22 Jun 2014)
899 ## Changes in this version:
903 - If the receiver gets bogus filenames from the sender (an unexpected leading
904 slash or a `..` infix dir), exit with an error. This prevents a malicious
905 sender from trying to inject filenames that would affect an area outside the
906 destination directories.
908 - Fixed a failure to remove the partial-transfer temp file when interrupted
909 (and rsync is not saving the partial files).
911 - Changed the chown/group/xattr-set order to avoid losing some security-
912 related xattr info (that would get cleared by a chown).
914 - Fixed a bug in the xattr-finding code that could make a non-root-run
915 receiver not able to find some xattr numbers.
917 - Fixed a bug in the early daemon protocol where a timeout failed to be
918 honored (e.g. if the remote side fails to send us the initial protocol
921 - Fixed unintended inclusion of commas in file numbers in the daemon log.
923 - We once again send the 'f' sub-flag (of `-e`) to the server side so it knows
924 that we can handle incremental-recursion directory errors properly in older
927 - Fixed an issue with too-aggressive keep-alive messages causing a problem for
928 older rsync versions early in the transfer.
930 - Fixed an incorrect message about backup-directory-creation when using
931 `--dry-run` and the backup dir is not an absolute path.
933 - Fixed a bug where a failed deletion and/or a failed sender-side removal
934 would not affect the exit code.
936 - Fixed a bug that caused a failure when combining `--delete-missing-args`
937 with `--xattrs` and/or `--acls`.
939 - Fixed a strange `dir_depth` assertion error that was caused by empty-dir
940 removals and/or duplicate files in the transfer.
942 - Fixed a problem with `--info=progress2`'s output stats where rsync would
943 only update the stats at the end of each file's transfer. It now uses the
944 data that is flowing for the current file, making the stats more accurate
947 - Fixed an itemize bug that affected the combo of `--link-dest`, `-X`, and
950 - Fixed a problem with delete messages not appearing in the log file when the
951 user didn't use `--verbose`.
953 - Improve chunked xattr reading for OS X.
955 - Removed an attempted hard-link xattr optimization that was causing a
956 transfer failure. This removal is flagged in the compatibility code, so if a
957 better fix can be discovered, we have a way to flip it on again.
959 - Fixed a bug when the receiver is not configured to be able to hard link
960 symlimks/devices/special-file items but the sender sent some of these items
961 flagged as hard-linked.
963 - We now generate a better error if the buffer overflows in `do_mknod()`.
965 - Fixed a problem reading more than 16 ACLs on some OSes.
967 - Fixed the reading of the secrets file to avoid an infinite wait when the
970 - Fixed a parsing problem in the `--usermap`/`--groupmap` options when using
973 - Switched Cygwin back to using socketpair `pipes` to try to speed it up.
975 - Added knowledge of a few new options to rrsync.
979 - Tweaked the temp-file naming when `--temp-dir=DIR` is used: the temp-file
980 names will not get a '.' prepended.
982 - Added support for a new-compression idiom that does not compress all the
983 matching data in a transfer. This can help rsync to use less cpu when a
984 transfer has a lot of matching data, and also makes rsync compatible with a
985 non-bundled zlib. See the `--new-compress` and `--old-compress` options in
988 - Added the rsync-no-vanished shell script. (See the support dir.)
990 - Made configure more prominently mention when we failed to find yodl (in case
991 the user wants to be able to generate manpages from `*.yo` files).
993 - Have manpage mention how a daemon's max-verbosity setting affects info and
994 debug options. Also added more clarification on backslash removals for
995 excludes that contain wildcards.
997 - Have configure check if for the attr lib (for getxattr) for those systems
998 that need to link against it explicitly.
1000 - Change the early dir-creation logic to only use that idiom in an
1001 inc-recursive copy that is preserving directory times. e.g. using
1002 `--omit-dir-times` will avoid these early directories being created.
1004 - Fix a bug in `cmp_time()` that would return a wrong result if the 2 times
1005 differed by an amount greater than what a `time_t` can hold.
1007 ### DEVELOPER RELATED:
1009 - We now include an example systemd file (in packaging/systemd).
1011 - Tweaked configure to make sure that any intended use of the included popt
1012 and/or zlib code is put early in the CFLAGS.
1014 ------------------------------------------------------------------------------
1016 # NEWS for rsync 3.1.0 (28 Sep 2013)
1018 ## Changes in this version:
1020 ### PROTOCOL NUMBER:
1022 - The protocol number was changed to 31.
1026 - Output numbers in 3-digit groups by default (e.g. 1,234,567). See the
1027 `--human-readable` option for a way to turn it off. See also the daemon's
1028 `log format` parameter and related command-line options (including
1029 `--out-format`) for a modifier that can be used to request digit-grouping or
1030 human-readable output in log escapes. (Note that log output is unchanged by
1033 - The `--list-only` option is now affected by the `--human-readable` setting.
1034 It will display digit groupings by default, and unit suffixes if higher
1035 levels of readability are requested. Also, the column width for the size
1036 output has increased from 11 to 14 characters when human readability is
1037 enabled. Use `--no-h` to get the old-style output and column size.
1039 - The output of the `--progress` option has changed: the string `xfer` was
1040 shortened to `xfr`, and the string `to-check` was shortened to `to-chk`,
1041 both designed to make room for the (by default) wider display of file size
1042 numbers without making the total line-length longer. Also, when incremental
1043 recursion is enabled, the string `ir-chk` will be used instead of `to-chk`
1044 up until the incremental-recursion scan is done, letting you know that the
1045 value to check and the total value will still be increasing as new files are
1048 - Enhanced the `--stats` output: 1) to mention how many files were created
1049 (protocol >= 28), 2) to mention how many files were deleted (a new line for
1050 protocol 31, but only output when `--delete` is in effect), and 3) to follow
1051 the file-count, created-count, and deleted-count with a subcount list that
1052 shows the counts by type. The wording of the transferred count has also
1053 changed so that it is clearer that it is only a count of regular files.
1057 - Fixed a bug in the iconv code when EINVAL or EILSEQ is returned with a full
1060 - Fixed some rare bugs in `--iconv` processing that might cause a multi-byte
1061 character to get translated incorrectly.
1063 - Fixed a bogus `vanished file` error if some files were specified with `./`
1064 prefixes and others were not.
1066 - Fixed a bug in `--sparse` where an extra gap could get inserted after a
1069 - Changed the way `--progress` overwrites its prior output in order to make it
1070 nearly impossible for the progress to get overwritten by an error.
1072 - Improved the propagation of abnormal-exit error messages. This should help
1073 the client side to receive errors from the server when it is exiting
1074 abnormally, and should also avoid dying with an `connection unexpectedly
1075 closed` exit when the closed connection is really expected.
1077 - The sender now checks each file it plans to remove to ensure that it hasn't
1078 changed from the first stat's info. This helps to avoid losing file data
1079 when the user is not using the option in a safe manner.
1081 - Fixed a data-duplication bug in the compress option that made compression
1082 less efficient. This improves protocol 31 onward, while behaving in a
1083 compatible (buggy) manner with older rsync protocols.
1085 - When creating a temp-file, rsync is now a bit smarter about it dot-char
1086 choices, which can fix a problem on OS X with names that start with `..`.
1088 - Rsync now sets a cleanup flag for `--inplace` and `--append` transfers that
1089 will flush the write buffer if the transfer aborts. This ensures that more
1090 received data gets written out to the disk on an aborted transfer (which is
1091 quite helpful on a slow, flaky connection).
1093 - The reads that `map_ptr()` now does are aligned on 1K boundaries. This helps
1094 some filesystems and/or files that don't like unaligned reads.
1096 - Fix an issue in the msleep() function if time jumps backwards.
1098 - Fix daemon-server module-name splitting bug where an arg would get split
1099 even if `--protect-args` was used.
1103 - Added the `--remote-option=OPT` (`-M OPT`) command-line option that is
1104 useful for things like sending a remote `--log-file=FILE` or `--fake-super`
1107 - Added the `--info=FLAGS` and `--debug=FLAGS` options to allow finer-grained
1108 control over what is output. Added an extra type of `--progress` output
1109 using `--info=progress2`.
1111 - The `--msgs2stderr` option can help with debugging rsync by allowing the
1112 debug messages to get output to stderr rather than travel via the socket
1115 - Added the `--delete-missing-args` and `--ignore-missing-args` options to
1116 either delete or ignore user-specified files on the receiver that are
1117 missing on the sender (normally the absence of user-specified files
1118 generates an error).
1120 - Added a `T` (terabyte) category to the `--human-readable` size suffixes.
1122 - Added the `--usermap`/`--groupmap`/`--chown` options for manipulating file
1123 ownership during the copy.
1125 - Added the `%C` escape to the log-output handling, which will output the MD5
1126 checksum of any transferred file, or all files if `--checksum` was specified
1127 (when protocol 30 or above is in effect).
1129 - Added the `reverse lookup` parameter to the rsync daemon config file to
1130 allow reverse-DNS lookups to be disabled.
1132 - Added a forward-DNS lookup for the daemon's hosts allow/deny config. Can be
1133 disabled via `forward lookup` parameter (defaults to enabled).
1135 - Added a way for more than one group to be specified in the daemon's config
1136 file, including a way to specify that you want all of the specified user's
1137 groups without having to name them. Also changed the daemon to complain
1138 about an inability to set explicitly-specified uid/gid values, even when not
1139 run by a super-user.
1141 - The daemon now tries to send the user the error messages from the pre-xfer
1142 exec script when it fails.
1144 - Improved the use of alt-dest options into an existing hierarchy of files: If
1145 a match is found in an alt-dir, it takes precedence over an existing file.
1146 (We'll need to wait for a future version before attribute-changes on
1147 otherwise unchanged files are safe when using an existing hierarchy.)
1149 - Added per-user authorization options and group-authorization support to the
1150 daemon's `auth users` parameter.
1152 - Added a way to reference environment variables in a daemon's config file
1153 (using %VAR% references).
1155 - When replacing a non-dir with a symlink/hard-link/device/special-file, the
1156 update should now be done in an atomic manner.
1158 - Avoid re-sending xattr info for hard-linked files w/the same xattrs
1161 - The backup code was improved to use better logic maintaining the backup
1162 directory hierarchy. Also, when a file is being backed up, rsync tries to
1163 hard-link it into place so that the upcoming replacement of the destination
1164 file will be atomic (for the normal, non-inplace logic).
1166 - Added the ability to synchronize nanosecond modified times.
1168 - Added a few more default suffixes for the `dont compress` settings.
1170 - Added the checking of the `RSYNC_PROTECT_ARGS` environment variable to allow
1171 the default for the `--protect-args` command-line option to be overridden.
1173 - Added the `--preallocate` command-line option.
1175 - Allow `--password-file=-` to read the password from stdin (filename `-`).
1177 - Rsync now comes packaged with an rsync-ssl helper script that can be used to
1178 contact a remote rsync daemon using a piped-stunnel command. It also
1179 includes an stunnel config file to run the server side to support ssl daemon
1180 connections. See the packaging/lsb/rsync.spec file for one way to package
1181 the resulting files. (Suggestions for how to make this even easier to
1182 install & use are welcomed.)
1184 - Improved the speed of some `--inplace` updates when there are lots of
1185 identical checksum blocks that end up being unusable.
1187 - Added the `--outbuf=N|L|B` option for choosing the output buffering.
1189 - Repeating the `--fuzzy` option now causes the code to look for fuzzy matches
1190 inside alt-dest directories too.
1192 - The `--chmod` option now supports numeric modes, e.g. `--chmod=644,D755`
1194 - Added some Solaris xattr code.
1196 - Made an rsync daemon (the listening process) exit with a 0 status when it
1197 was signaled to die. This helps launchd.
1199 - Improved the `RSYNC_*` environment variables for the pre-xfer exec script:
1200 when a daemon is sent multiple request args, they are now joined into a
1201 single return value (separated by spaces) so that the `RSYNC_REQUEST`
1202 environment variable is accurate for any `pre-xfer exec`. The values in
1203 `RSYNC_ARG#` vars are no longer truncated at the `.` arg (prior to the
1204 request dirs/files), so that all the requested values are also listed
1205 (separately) in `RSYNC_ARG#` variables.
1209 - Added an `instant-rsyncd` script to the support directory, which makes it
1210 easy to configure a simple rsync daemon in the current directory.
1212 - Added the `mapfrom` and `mapto` scripts to the support directory, which
1213 makes it easier to do user/group mapping in a local transfer based on
1214 passwd/group files from another machine.
1216 - There's a new, improved version of the lsh script in the support dir: it's
1217 written in perl and supports `-u` without resorting to using sudo (when run
1218 as root). The old shell version is now named lsh.sh.
1220 - There is a helper script named rsync-slash-strip in the support directory
1221 for anyone that wants to change the way rsync handles args with trailing
1222 slashes. (e.g. arg/ would get stripped to arg while arg/. would turn into
1227 - The I/O code was rewritten to be simpler and do bigger buffered reads over
1228 the socket. The I/O between the receiver and the generator was changed to be
1229 standard multiplexed-I/O (like that over the socket).
1231 - The sender tries to use any dead time while the generator is looking for
1232 files to transfer in order to do sender-side directory scanning in a more
1235 - A daemon can now inform a client about a daemon-configured timeout value so
1236 that the client can assist in the keep-alive activity (protocol 31).
1238 - The filter code received some refactoring to make it more extendable, to
1239 read better, and do better sanity checking.
1241 - Really big numbers are now output using our own big-num routine rather than
1242 casting them to a double and using a %.0f conversion.
1244 - The `pool_alloc` library has received some minor improvements in alignment
1247 - Added `init_stat_x()` function to avoid duplication of acl/xattr init code.
1249 - The included zlib was upgraded from 1.2.3 to 1.2.8.
1251 - Rsync can now be compiled to use an unmodified zlib library instead of the
1252 tweaked one that is included with rsync. This will eventually become the
1253 default, at which point we'll start the countdown to removing the included
1254 zlib. Until then, feel free to configure using:
1256 ./configure `--with-included-zlib=no`
1258 ### DEVELOPER RELATED:
1260 - Added more conditional debug output.
1262 - Fixed some build issues for Android and Minix.
1264 ------------------------------------------------------------------------------
1266 # NEWS for rsync 3.0.9 (23 Sep 2011)
1268 ## Changes in this version:
1272 - Fix a crash bug in checksum scanning when `--inplace` is used.
1274 - Fix a hang if a hard-linked file cannot be opened by the sender (e.g. if it
1275 has no read permission).
1277 - Fix preservation of a symlink's system xattrs (e.g. selinux) on Linux.
1279 - Fix a memory leak in the xattr code.
1281 - Fixed a bug with `--delete-excluded` when a filter merge file has a rule
1282 that specifies a receiver-only side restriction.
1284 - Fix a bug with the modifying of unwritable directories.
1286 - Fix `--fake-super`'s interaction with `--link-dest` same-file comparisons.
1288 - Fix the updating of the `curr_dir` buffer to avoid a duplicate slash.
1290 - Fix the directory permissions on an implied dot-dir when using `--relative`
1291 (e.g. /outside/path/././send/path).
1293 - Fixed some too-long sleeping instances when using `--bwlimit`.
1295 - Fixed when symlink ownership difference-checking gets compiled into
1296 `unchanged_attrs()`.
1298 - Improved the socket-error reporting when multiple protocols fail.
1300 - Fixed a case where a socket error could reference just-freed memory.
1302 - Failing to use a password file that was specified on the command-line is now
1305 - Fix the non-root updating of directories that don't have the read and/or
1308 - Make daemon-excluded file errors more error-like.
1310 - Fix a compilation issue on older C compilers (due to a misplaced var
1313 - Make configure avoid finding socketpair on Cygwin.
1315 - Avoid trying to reference `SO_BROADCAST` if the OS doesn't support it.
1317 - Fix some issues with the post-processing of the manpages.
1319 - Fixed the user home-dir handling in the lsh script. (See the support dir.)
1321 - Some minor manpage improvements.
1323 ------------------------------------------------------------------------------
1325 # NEWS for rsync 3.0.8 (26 Mar 2011)
1327 ## Changes in this version:
1331 - Fixed two buffer-overflow issues: one where a directory path that is exactly
1332 MAXPATHLEN was not handled correctly, and one handling a `--backup-dir` that
1333 is extra extra large.
1335 - Fixed a data-corruption issue when preserving hard-links without preserving
1336 file ownership, and doing deletions either before or during the transfer
1337 (CVE-2011-1097). This fixes some assert errors in the hard-linking code, and
1338 some potential failed checksums (via `-c`) that should have matched.
1340 - Fixed a potential crash when an rsync daemon has a filter/exclude list and
1341 the transfer is using ACLs or xattrs.
1343 - Fixed a hang if a really large file is being processed by an rsync that
1344 can't handle 64-bit numbers. Rsync will now complain about the file being
1345 too big and skip it.
1347 - For devices and special files, we now avoid gathering useless ACL and/or
1348 xattr information for files that aren't being copied. (The un-copied files
1349 are still put into the file list, but there's no need to gather data that is
1350 not going to be used.) This ensures that if the user uses `--no-D`, that
1351 rsync can't possibly complain about being unable to gather extended
1352 information from special files that are in the file list (but not in the
1355 - Properly handle requesting remote filenames that start with a dash. This
1356 avoids a potential error where a filename could be interpreted as a (usually
1359 - Fixed a bug in the comparing of upper-case letters in file suffixes for
1362 - If an rsync daemon has a module configured without a path setting, rsync
1363 will now disallow access to that module.
1365 - If the destination arg is an empty string, it will be treated as a reference
1366 to the current directory (as 2.x used to do).
1368 - If rsync was compiled with a newer time-setting function (such as lutimes),
1369 rsync will fall-back to an older function (such as utimes) on a system where
1370 the newer function is not around. This helps to make the rsync binary more
1371 portable in mixed-OS-release situations.
1373 - Fixed a batch-file writing bug that would not write out the full set of
1374 compatibility flags that the transfer was using. This fixes a potential
1375 protocol problem for a batch file that contains a sender-side I/O error: it
1376 would have been sent in a way that the batch-reader wasn't expecting.
1378 - Some improvements to the hard-linking code to ensure that device-number
1379 hashing is working right, and to supply more information if the hard-link
1382 - The `--inplace` code was improved to not search for an impossible checksum
1383 position. The quadruple-verbose chunk[N] message will now mention when an
1384 inplace chunk was handled by a seek rather than a read+write.
1386 - Improved ACL mask handling, e.g. for Solaris.
1388 - Fixed a bug that prevented `--numeric-ids` from disabling the translation of
1389 user/group IDs for ACLs.
1391 - Fixed an issue where an xattr and/or ACL transfer that used an alt-dest
1392 option (e.g. `--link-dest`) could output an error trying to itemize the
1393 changes against the alt-dest directory's xattr/ACL info but was instead
1394 trying to access the not-yet-existing new destination directory.
1396 - Improved xattr system-error messages to mention the full path to the file.
1398 - The `--link-dest` checking for identical symlinks now avoids considering
1399 attribute differences that cannot be changed on the receiver.
1401 - Avoid trying to read/write xattrs on certain file types for certain OSes.
1402 Improved configure to set `NO_SYMLINK_XATTRS`, `NO_DEVICE_XATTRS`, and/or
1403 `NO_SPECIAL_XATTRS` defines in config.h.
1405 - Improved the unsafe-symlink errors messages.
1407 - Fixed a bug setting xattrs on new files that aren't user writable.
1409 - Avoid re-setting xattrs on a hard-linked file w/the same xattrs.
1411 - Fixed a bug with `--fake-super` when copying files and dirs that aren't user
1414 - Fixed a bug where a sparse file could have its last sparse block turned into
1415 a real block when rsync sets the file size (requires ftruncate).
1417 - If a temp-file name is too long, rsync now avoids truncating the name in the
1418 middle of adjacent high-bit characters. This prevents a potential filename
1419 error if the filesystem doesn't allow a name to contain an invalid
1420 multi-byte sequence.
1422 - If a muli-protocol socket connection fails (i.e., when contacting a daemon),
1423 we now report all the failures, not just the last one. This avoids losing a
1424 relevant error (e.g. an IPv4 connection-refused error) that happened before
1425 the final error (e.g. an IPv6 protocol-not-supported error).
1427 - Generate a transfer error if we try to call chown with a `-1` for a uid or a
1428 gid (which is not settable).
1430 - Fixed the working of `--force` when used with `--one-file-system`.
1432 - Fix the popt arg parsing so that an option that doesn't take an arg will
1433 reject an attempt to supply one (can configure `--with-included-popt` if
1434 your system's popt library doesn't yet have this fix).
1436 - A couple minor option tweaks to the rrsync script, and also some regex
1437 changes that make vim highlighting happier. (See the support dir.)
1439 - Fixed some issues in the mnt-excl script. (See the support dir.)
1441 - Various manpage improvements.
1445 - Added `.hg/` to the default cvs excludes (see `-C` & `--cvs-exclude`).
1447 ### DEVELOPER RELATED:
1449 - Use lchmod() whenever it is available (not just on symlinks).
1451 - A couple fixes to the `socketpair_tcp()` routine.
1453 - Updated the helper scripts in the packaging subdirectory.
1455 - Renamed configure.in to configure.ac.
1457 - Fixed configure's checking for iconv routines for newer OS X versions.
1459 - Fixed the testsuite/xattrs.test script on OS X.
1461 ------------------------------------------------------------------------------
1463 # NEWS for rsync 3.0.7 (31 Dec 2009)
1465 ## Changes in this version:
1469 - Fixed a bogus free when using `--xattrs` with `--backup`.
1471 - Avoid an error when `--dry-run` was trying to stat a prior hard-link file
1472 that hasn't really been created.
1474 - Fixed a problem with `--compress` (`-z`) where the receiving side could
1475 return the error "`inflate (token) returned -5`".
1477 - Fixed a bug where `--delete-during` could delete in a directory before it
1478 noticed that the sending side sent an I/O error for that directory (both
1479 sides of the transfer must be at least 3.0.7).
1481 - Improved `--skip-compress`'s error handling of bad character-sets and got
1482 rid of a lingering debug fprintf().
1484 - Fixed the daemon's conveyance of `io_error` value from the sender.
1486 - An rsync daemon use seteuid() (when available) if it used setuid().
1488 - Get the permissions right on a `--fake-super` transferred directory that
1489 needs more owner permissions to emulate root behavior.
1491 - An absolute-path filter rule (i.e. with a '/' modifier) no longer loses its
1492 modifier when sending the filter rules to the remote rsync.
1494 - Improved the "`--delete does not work without -r or -d`" message.
1496 - Improved rsync's handling of `--timeout` to avoid a weird timeout case where
1497 the sender could timeout even though it has recently written data to the
1498 socket (but hasn't read data recently, due to the writing).
1500 - Some misc manpage improvements.
1502 - Fixed the chmod-temp-dir testsuite on a system without /var/tmp.
1504 - Make sure that a timeout specified in the daemon's config is used as a
1505 maximum timeout value when the user also specifies a timeout.
1507 - Improved the error-exit reporting when rsync gets an error trying to cleanup
1508 after an error: the initial error is reported.
1510 - Improved configure's detection of IPv6 for Solaris and Cygwin.
1512 - The AIX sysacls routines will now return ENOSYS if ENOTSUP is missing.
1514 - Made our (only used if missing) getaddrinfo() routine use `inet_pton()`
1515 (which we also provide) instead of `inet_aton()`.
1517 - The exit-related debug messages now mention the program's role so it is
1518 clear who output what message.
1520 ### DEVELOPER RELATED:
1522 - Got rid of type-punned compiler warnings output by newer gcc versions.
1524 - The Makefile now ensures that proto.h will be rebuilt if config.h changes.
1526 - The testsuite no longer uses `id -u`, so it works better on Solaris.
1528 ------------------------------------------------------------------------------
1530 # NEWS for rsync 3.0.6 (8 May 2009)
1532 ## Changes in this version:
1536 - Fixed a `--read-batch` hang when rsync is reading a batch file that was
1537 created from an incremental-recursion transfer.
1539 - Fixed the daemon's socket code to handle the simultaneous arrival of
1540 multiple connections.
1542 - Fix `--safe-links`/`--copy-unsafe-links` to properly handle symlinks that
1543 have consecutive slashes in the value.
1545 - Fixed the parsing of an `[IPv6_LITERAL_ADDR]` when a USER@ is prefixed.
1547 - The sender now skips a (bogus) symlink that has a 0-length value, which
1548 avoids a transfer error in the receiver.
1550 - Fixed a case where the sender could die with a tag-0 error if there was an
1551 I/O during the sending of the file list.
1553 - Fixed the rrsync script to avoid a server-side problem when `-e` is at the
1554 start of the short options.
1556 - Fixed a problem where a vanished directory could turn into an exit code 23
1557 instead of the proper exit code 24.
1559 - Fixed the `--iconv` conversion of symlinks when doing a local copy.
1561 - Fixed a problem where `--one-file-system` was not stopping deletions on the
1562 receiving side when a mount-point directory did not match a directory in the
1565 - Fixed the dropping of an ACL mask when no named ACL values were present.
1567 - Fixed an ACL/xattr corruption issue where the `--backup` option could cause
1568 rsync to associate the wrong ACL/xattr information with received files.
1570 - Fixed the use of `--xattrs` with `--only-write-batch`.
1572 - Fixed the use of `--dry-run` with `--read-batch`.
1574 - Fixed configure's erroneous use of target.
1576 - Fixed configure's `--disable-debug` option.
1578 - Fixed a run-time issue for systems that can't find `iconv_open()` by adding
1579 the `--disable-iconv-open` configure option.
1581 - Complain and die if the user tries to combine `--remove-source-files` (or
1582 the deprecated `--remove-sent-files`) with `--read-batch`.
1584 - Fixed an failure transferring special files from Solaris to Linux.
1586 ------------------------------------------------------------------------------
1588 # NEWS for rsync 3.0.5 (28 Dec 2008)
1590 ## Changes in this version:
1594 - Initialize xattr data in a couple spots in the hlink code, which avoids a
1595 crash when the xattr pointer's memory happens to start out non-zero. Also
1596 fixed the itemizing of an alt-dest file's xattrs when hard-linking.
1598 - Don't send a bogus `-` option to an older server if there were no short
1601 - Fixed skipping of unneeded updates in a batch file when incremental
1602 recursion is active. Added a test for this. Made batch-mode handle `redo`
1603 files properly (and without hanging).
1605 - Fix the %P logfile escape when the daemon logs from inside a chroot.
1607 - Fixed the use of `-s` (`--protect-args`) when used with a remote source or
1608 destination that had an empty path (e.g. `host:`). Also fixed a problem when
1609 `-s` was used when accessing a daemon via a remote-shell.
1611 - Fixed the use of a dot-dir path (e.g. foo/./bar) inside a `--files-from`
1612 file when the root of the transfer isn't the current directory.
1614 - Fixed a bug with `-K --delete` removing symlinks to directories when
1615 incremental recursion is active.
1617 - Fixed a hard to trigger hang when using `--remove-source-files`.
1619 - Got rid of an annoying delay when accessing a daemon via a remote-shell.
1621 - Properly ignore (superfluous) source args on a `--read-batch` command.
1623 - Improved the manpage's description of the `*` wildcard to remove the
1624 confusing `non-empty` qualifier.
1626 - Fixed reverse lookups in the compatibility-library version of getnameinfo().
1628 - Fixed a bug when using `--sparse` on a sparse file that has over 2GB of
1629 consecutive sparse data.
1631 - Avoid a hang when using at least 3 `--verbose` options on a transfer with a
1632 client sender (which includes local copying).
1634 - Fixed a problem with `--delete-delay` reporting an error when it was ready
1635 to remove a directory that was now gone.
1637 - Got rid of a bunch of `warn_unused_result` compiler warnings.
1639 - If an ftruncate() on a received file fails, it now causes a partial-
1642 - Allow a path with a leading `//` to be preserved (CYGWIN only).
1646 - Made the atomic-rsync script able to perform a fully atomic update of the
1647 copied hierarchy when the destination is setup using a particular symlink
1648 idiom. (See the support dir.)
1650 ------------------------------------------------------------------------------
1652 # NEWS for rsync 3.0.4 (6 Sep 2008)
1654 ## Changes in this version:
1658 - Fixed a bug in the hard-linking code where it would sometimes try to
1659 allocate 0 bytes of memory (which fails on some OSes, such as AIX).
1661 - Fixed the hard-linking of files from a device that has a device number of 0
1662 (which seems to be a common device number on NetBSD).
1664 - Fixed the handling of a `--partial-dir` that cannot be created. This
1665 particularly impacts the `--delay-updates` option (since the files cannot be
1666 delayed without a partial-dir), and was potentially destructive if the
1667 `--remove-source-files` was also specified.
1669 - Fixed a couple issues in the `--fake-super` handling of xattrs when the
1670 destination files have root-level attributes (e.g. selinux values) that a
1671 non-root copy can't affect.
1673 - Improved the keep-alive check in the generator to fire consistently in
1674 incremental-recursion mode when `--timeout` is enabled.
1676 - The `--iconv` option now converts the content of a symlink too, instead of
1677 leaving it in the wrong character-set (requires 3.0.4 on both sides of the
1680 - When using `--iconv`, if a filename fails to convert on the receiving side,
1681 this no longer makes deletions in the root-dir of the transfer fail silently
1682 (the user now gets a warning about deletions being disabled due to IO error
1683 as long as `--ignore-errors` was not specified).
1685 - When using `--iconv`, if a server-side receiver can't convert a filename,
1686 the error message sent back to the client no longer mangles the name with
1687 the wrong charset conversion.
1689 - Fixed a potential alignment issue in the IRIX ACL code when allocating the
1690 initial `struct acl` object. Also, cast mallocs to avoid warnings.
1692 - Changed some errors that were going to stdout to go to stderr.
1694 - Made `human_num()` and `human_dnum()` able to output a negative number
1695 (rather than outputting a cryptic string of punctuation).
1699 - Rsync will avoid sending an `-e` option to the server if an older protocol
1700 is requested (and thus the option would not be useful). This lets the user
1701 specify the `--protocol=29` option to access an overly-restrictive server
1702 that is rejecting the protocol-30 use of `-e` to the server.
1704 - Improved the message output for an `RERR_PARTIAL` exit.
1706 ### DEVELOPER RELATED:
1708 - The Makefile will not halt for just a timestamp change on the Makefile or
1709 the configure files, only for actual changes in content.
1711 - Changed some commands in the testsuite's xattrs.test that called `rsync`
1712 instead of `$RSYNC`.
1714 - Enhanced the release scripts to be able to handle a branch release and to do
1715 even more consistency checks on the files.
1717 ------------------------------------------------------------------------------
1719 # NEWS for rsync 3.0.3 (29 Jun 2008)
1721 ## Changes in this version:
1725 - Fixed a wildcard matching problem in the daemon when a module has `use
1728 - Fixed a crash bug in the hard-link code.
1730 - Fixed the sending of xattr directory information when the code finds a
1731 `--link-dest` or `--copy-dest` directory with unchanged xattrs -- the
1732 destination directory now gets these unchanged xattrs properly applied.
1734 - Fixed an xattr-sending glitch that could cause an `Internal abbrev` error.
1736 - Fixed the combination of `--xattrs` and `--backup`.
1738 - The generator no longer allows a '.' dir to be excluded by a daemon-exclude
1741 - Fixed deletion handling when copying a single, empty directory (with no
1742 files) to a differently named, non-existent directory.
1744 - Fixed the conversion of spaces into dashes in the %M log escape.
1746 - Fixed several places in the code that were not returning the right errno
1747 when a function failed.
1749 - Fixed the backing up of a device or special file into a backup dir.
1751 - Moved the setting of the socket options prior to the connect().
1753 - If rsync exits in the middle of a `--progress` output, it now outputs a
1754 newline to help prevent the progress line from being overwritten.
1756 - Fixed a problem with how a destination path with a trailing slash or a
1757 trailing dot-dir was compared against the daemon excludes.
1759 - Fixed the sending of large (size > 16GB) files when talking to an older
1760 rsync (protocols < 30): we now use a compatible block size limit.
1762 - If a file's length is so huge that we overflow a checksum buffer count (i.e.
1763 several hundred TB), warn the user and avoid sending an invalid checksum
1764 struct over the wire.
1766 - If a source arg is excluded, `--relative` no longer adds the excluded arg's
1767 implied dirs to the transfer. This fix also made the exclude check happen in
1768 the better place in the sending code.
1770 - Use the `overflow_exit()` function for overflows, not `out_of_memory()`.
1772 - Improved the code to better handle a system that has only 32-bit file
1777 - The rsyncd.conf manpage now consistently refers to the parameters in the
1778 daemon config file as `parameters`.
1780 - The description of the `--inplace` option was improved.
1784 - Added a new script in the support directory, deny-rsync, which allows an
1785 admin to (temporarily) replace the rsync command with a script that sends an
1786 error message to the remote client via the rsync protocol.
1788 ### DEVELOPER RELATED:
1790 - Fixed a testcase failure if the tests are run as root and made some
1791 compatibility improvements.
1793 - Improved the daemon tests, including checking module comments, the listing
1794 of files, and the ensuring that daemon excludes can't affect a dot-dir arg.
1796 - Improved some build rules for those that build in a separate directory from
1797 the source, including better install rules for the manpages, and the fixing
1798 of a proto.h-tstamp rule that could make the binaries get rebuild without
1801 - Improved the testsuite to work around a problem with some utilities (e.g.
1802 `cp -p` & `touch -r`) rounding sub-second timestamps.
1804 - Ensure that the early patches don't cause any generated-file hunks to
1805 bleed-over into patches that follow.

1830 # NEWS for rsync 3.0.1 (3 Apr 2008)
1832 ## Changes in this version:
1834 ### NOTABLE CHANGES IN BEHAVIOR:
1836 - Added the 'c'-flag to the itemizing of non-regular files so that the
1837 itemized output doesn't get hidden if there were no attribute changes, and
1838 also so that the itemizing of a `--copy-links` run will distinguish between
1839 copying an identical non-regular file and the creation of a revised version
1840 with a new value (e.g. a changed symlink referent, a new device number,
1845 - Fixed a crash bug when a single-use rsync daemon (via remote shell) was run
1846 without specifying a `--config=FILE` option.
1848 - Fixed a crash when backing up a directory that has a default ACL.
1850 - Fixed a bug in the handling of xattr values that could cause rsync to not
1851 think that a file's extended attributes are up-to-date.
1853 - Fixed the working of `--fake-super` with `--link-dest` and `--xattrs`.
1855 - Fixed a hang when combining `--dry-run` with `--remove-source-files`.
1857 - Fixed a bug with `--iconv`'s handling of files that cannot be converted: a
1858 failed name can no longer cause a transfer failure.
1860 - Fixed the building of the rounding.h file on systems that need custom
1861 CPPFLAGS to be used. Also improved the error reporting if the building of
1864 - Fixed the use of the `--protect-args` (`-s`) option when talking to a
1867 - Fixed the `--ignore-existing` option's protection of files on the receiver
1868 that are non-regular files on the sender (e.g. if a symlink or a dir on the
1869 sender is trying to replace a file on the receiver). The reverse protection
1870 (protecting a dir/symlink/device from being replaced by a file) was already
1873 - Fixed an assert failure if `--hard-links` is combined with an option that
1874 can skip a file in a set of hard-linked files (i.e. `--ignore-existing`,
1875 `--append`, etc.), without skipping all the files in the set.
1877 - Avoid setting the modify time on a directory that already has the right
1878 modify time set. This avoids tweaking the dir's ctime.
1880 - Improved the daemon-exclude handling to do a better job of applying the
1881 exclude rules to path entries. It also sends the user an error just as if
1882 the files were actually missing (instead of silently ignoring the user's
1883 args), and avoids sending the user the filter-action messages for these
1884 non-user-initiated rules.
1886 - Fixed some glitches with the dry-run code's missing-directory handling,
1887 including a problem when combined with `--fuzzy`.
1889 - Fixed some glitches with the skipped-directory handling.
1891 - Fixed the 'T'-flag itemizing of symlinks when `--time` isn't preserved.
1893 - Fixed a glitch in the itemizing of permissions with the `-E` option.
1895 - The `--append` option's restricting of transfers to those that add data no
1896 longer prevents the updating of non-content changes to otherwise up-to-date
1897 files (i.e. those with the same content but differing permissions,
1898 ownership, xattrs, etc.).
1900 - Don't allow `--fake-super` to be specified with `-XX` (double `--xattrs`)
1901 because the options conflict. If a daemon has `fake super` enabled, it
1902 automatically downgrades a `-XX` request to `-X`.
1904 - Fixed a couple bugs in the parsing of daemon-config excludes that could make
1905 a floating exclude rule get treated as matching an absolute path.
1907 - A daemon doesn't try to auto-refuse the `iconv` option if iconv-support
1908 wasn't compiled in to the daemon (avoiding a warning in the logs).
1910 - Fixed the inclusion of per-dir merge files from implied dirs.
1912 - Fixed the rrsync script to work with the latest options that rsync sends,
1913 including its flag-specifying use of `-e` to the server. (See the support
1918 - Added the `--old-dirs` (`--old-d`) option to make it easier for a user to
1919 ask for file-listings with older rsync versions (this is easier than having
1920 to type `-r --exclude='/*/*'` manually).
1922 - When getting an error while asking an older rsync daemon for a file listing,
1923 rsync will try to notice if the error is a rejection of the `--dirs` (`-d`)
1924 option and let the user know how to work around the issue.
1926 - Added a few more `--no-OPTION` overrides.
1928 - Improved the documentation of the `--append` option.
1930 - Improved the documentation of the filter/exclude/include daemon parameters.
1934 - Fixed a couple minor bugs in the included popt library (ones which I sent to
1935 the official popt project for inclusion in the 1.14 release).
1937 - Fixed a stat() call that should have been `do_stat()` so that the proper
1938 normal/64-bit stat() function gets called. (Was in an area that should not
1939 have caused problems, though.)
1941 - Changed the file-glob code to do a directory scan without using the `glob`
1942 and `glob.h`. This lets us do the globbing with less memory churn, and also
1943 avoid adding daemon-excluded items to the returned args.
1945 ### DEVELOPER RELATED:
1947 - The configure script tries to get the user's compiler to not warn about
1948 unused function parameters if the build is not including one or more of the
1949 ACL/xattrs/iconv features.
1951 - The configure script now has better checks for figuring out if the included
1952 popt code should be used or not.
1954 - Fixed two testsuite glitches: avoid a failure if someone's `cd` command
1955 outputs the current directory when cd-ing to a relative path, and made the
1956 itemized test query how rsync was built to determine if it should expect
1957 hard-linked symlinks or not.
1959 - Updated the testsuite to verify that various bug fixes remain fixed.
1961 - The RPM spec file was updated to have: (1) comments for how to use the
1962 rsync-patch tar file, and (2) an /etc/xinetd.d/rsync file.
1964 - Updated the build scripts to work with a revised FTP directory structure.

1968 # NEWS for rsync 3.0.0 (1 Mar 2008)
1970 ## Changes in this version:
1972 ### PROTOCOL NUMBER:
1974 - The protocol number was changed to 30.
1976 ### NOTABLE CHANGES IN BEHAVIOR:
1978 - The handling of implied directories when using `--relative` has changed to
1979 send them as directories (e.g. no implied dir is ever sent as a symlink).
1980 This avoids unexpected behavior and should not adversely affect most people.
1981 If you're one of those rare individuals who relied upon having an implied
1982 dir be duplicated as a symlink, you should specify the transfer of the
1983 symlink and the transfer of the referent directory as separate args. (See
1984 also `--keep-dirlinks` and `--no-implied-dirs`.) Also, exclude rules no
1985 longer have a partial effect on implied dirs.
1987 - Requesting a remote file-listing without specifying `-r` (`--recursive`) now
1988 sends the `-d` (`--dirs`) option to the remote rsync rather than sending
1989 `-r` along with an extra exclude of `/*/*`. If the remote rsync does not
1990 understand the `-d` option (i.e. it is 2.6.3 or older), you will need to
1991 either turn off `-d` (`--no-d`), or specify `-r --exclude='/*/*'` manually.
1993 - In `--dry-run` mode, the last line of the verbose summary text is output
1994 with a "(DRY RUN)" suffix to help remind you that no updates were made.
1995 Similarly, `--only-write-batch` outputs `(BATCH ONLY)`.
1997 - A writable rsync daemon with `use chroot` disabled now defaults to a
1998 symlink-munging behavior designed to make symlinks safer while also allowing
1999 absolute symlinks to be stored and retrieved. This also has the effect of
2000 making symlinks unusable while they're in the daemon's hierarchy. See the
2001 daemon's `munge symlinks` parameter for details.
2003 - Starting up an extra copy of an rsync daemon will not clobber the pidfile
2004 for the running daemon -- if the pidfile exists, the new daemon will exit
2005 with an error. This means that your wrapper script that starts the rsync
2006 daemon should be made to handle lock-breaking (if you want any automatic
2007 breaking of locks to be done).
2011 - A daemon with `use chroot = no` and excluded items listed in the daemon
2012 config file now properly checks an absolute-path arg specified for these
2013 options: `--compare-dest`, `--link-dest`, `--copy-dest`, `--partial-dir`,
2014 `--backup-dir`, `--temp-dir`, and `--files-from`.
2016 - A daemon can now be told to disable all user- and group-name translation on
2017 a per-module basis. This avoids a potential problem with a writable daemon
2018 module that has `use chroot` enabled -- if precautions weren't taken, a user
2019 could try to add a missing library and get rsync to use it. This makes rsync
2020 safer by default, and more configurable when id-translation is not desired.
2021 See the daemon's `numeric ids` parameter for full details.
2023 - A chroot daemon can now indicate which part of its path should affect the
2024 chroot call, and which part should become an inside-chroot path for the
2025 module. This allows you to have outside-the-transfer paths (such as for
2026 libraries) even when you enable chroot protection. The idiom used in the
2027 rsyncd.conf file is: `path = /chroot/dirs/./dirs/inside`
2029 - If a file's data arrived successfully on the receiving side but the rename
2030 of the temporary file to the destination file failed AND the
2031 `--remove-source-files` (or the deprecated `--remove-sent-files`) option was
2032 specified, rsync no longer erroneously removes the associated source file.
2034 - Fixed the output of `-ii` when combined with one of the `--*-dest` options:
2035 it now itemizes all the items, not just the changed ones.
2037 - Made the output of all file types consistent when using a `--*-dest` option.
2038 Prior versions would output too many creation events for matching items.
2040 - The code that waits for a child pid now handles being interrupted by a
2041 signal. This fixes a problem with the pre-xfer exec function not being able
2042 to get the exit status from the script.
2044 - A negated filter rule (i.e. with a '!' modifier) no longer loses the
2045 negation when sending the filter rules to the remote rsync.
2047 - Fixed a problem with the `--out-format` (aka `--log-format`) option %f: it
2048 no longer outputs superfluous directory info for a non-daemon rsync.
2050 - Fixed a problem with `-vv` (double `--verbose`) and `--stats` when `pushing`
2051 files (which includes local copies). Version 2.6.9 would complete the copy,
2052 but exit with an error when the receiver output its memory stats.
2054 - If `--password-file` is used on a non-daemon transfer, rsync now complains
2055 and exits. This should help users figure out that they can't use this option
2056 to control a remote shell's password prompt.
2058 - Make sure that directory permissions of a newly-created destination
2059 directory are handled right when `--perms` is left off.
2061 - The itemized output of a newly-created destination directory is now output
2062 as a creation event, not a change event.
2064 - Improved `--hard-link` so that more corner cases are handled correctly when
2065 combined with options such as `--link-dest` and/or `--ignore-existing`.
2067 - The `--append` option no longer updates a file that has the same size.
2069 - Fixed a bug when combining `--backup` and `--backup-dir` with `--inplace`:
2070 any missing backup directories are now created.
2072 - Fixed a bug when using `--backup` and `--inplace` with `--whole-file` or
2073 `--read-batch`: backup files are actually created now.
2075 - The daemon pidfile is checked and created sooner in the startup sequence.
2077 - If a daemon module's `path` value is not an absolute pathname, the code now
2078 makes it absolute internally (making it work properly).
2080 - Ensure that a temporary file always has owner-write permission while we are
2081 writing to it. This avoids problems with some network filesystems when
2082 transferring read-only files.
2084 - Any errors output about password-file reading no longer cause an error at
2085 the end of the run about a partial transfer.
2087 - The `--read-batch` option for protocol 30 now ensures that several more
2088 options are set correctly for the current batch file: `--iconv`, `--acls`,
2089 `--xattrs`, `--inplace`, `--append`, and `--append-verify`.
2091 - Using `--only-write-batch` to a daemon receiver now works properly (older
2092 versions would update some files while writing the batch).
2094 - Avoid outputting a "file has vanished" message when the file is a broken
2095 symlink and `--copy-unsafe-links` or `--copy-dirlinks` is used (the code
2096 already handled this for `--copy-links`).
2098 - Fixed the combination of `--only-write-batch` and `--dry-run`.
2100 - Fixed rsync's ability to remove files that are not writable by the file's
2101 owner when rsync is running as the same user.
2103 - When transferring large files, the sender's hashtable of checksums is kept
2104 at a more reasonable state of fullness (no more than 80% full) so that the
2105 scanning of the hashtable will not bog down as the number of blocks
2110 - A new incremental-recursion algorithm is now used when rsync is talking to
2111 another 3.x version. This starts the transfer going more quickly (before all
2112 the files have been found), and requires much less memory. See the
2113 `--recursive` option in the manpage for some restrictions.
2115 - Lowered memory use in the non-incremental-recursion algorithm for typical
2116 option values (usually saving from 21-29 bytes per file).
2118 - The default `--delete` algorithm is now `--delete-during` when talking to a
2119 3.x rsync. This is a faster scan than using `--delete-before` (which is the
2120 default when talking to older rsync versions), and is compatible with the
2121 new incremental recursion mode.
2123 - Rsync now allows multiple remote-source args to be specified rather than
2124 having to rely on a special space-splitting side-effect of the remote-
2125 shell. Additional remote args must specify the same host or an empty one
2126 (e.g. empty: `:file1` or `::module/file2`). For example, this means that
2127 local use of brace expansion now works: `rsync -av host:dir/{f1,f2} .`
2129 - Added the `--protect-args` (`-s`) option, that tells rsync to send most of
2130 the command-line args at the start of the transfer rather than as args to
2131 the remote-shell command. This protects them from space-splitting, and only
2132 interprets basic wildcard special shell characters (`*?[`).
2134 - Added the `--delete-delay` option, which is a more efficient way to delete
2135 files at the end of the transfer without needing a separate delete pass.
2137 - Added the `--acls` (`-A`) option to preserve Access Control Lists. This is
2138 an improved version of the prior patch that was available, and it even
2139 supports OS X ACLs. If you need to have backward compatibility with old,
2140 ACL-patched versions of rsync, apply the acls.diff file from the patches
2143 - Added the `--xattrs` (`-X`) option to preserve extended attributes. This is
2144 an improved version of the prior patch that was available, and it even
2145 supports OS X xattrs (which includes their resource fork data). If you need
2146 to have backward compatibility with old, xattr-patched versions of rsync,
2147 apply the xattrs.diff file from the patches dir.
2149 - Added the `--fake-super` option that allows a non-super user to preserve all
2150 attributes of a file by using a special extended-attribute idiom. It even
2151 supports the storing of foreign ACL data on your backup server. There is
2152 also an analogous `fake super` parameter for an rsync daemon.
2154 - Added the `--iconv` option, which allows rsync to convert filenames from one
2155 character-set to another during the transfer. The default is to make this
2156 feature available as long as your system has `iconv_open()`. If compilation
2157 fails, specify `--disable-iconv` to configure, and then rebuild. If you want
2158 rsync to perform character-set conversions by default, you can specify
2159 `--enable-iconv=CONVERT_STRING` with the default value for the `--iconv`
2160 option that you wish to use. For example, `--enable-iconv=.` is a good
2161 choice. See the rsync manpage for an explanation of the `--iconv` option's
2164 - A new daemon config parameter, `charset`, lets you control the character-
2165 set that is used during an `--iconv` transfer to/from a daemon module. You
2166 can also set your daemon to refuse `no-iconv` if you want to force the
2167 client to use an `--iconv` transfer (requiring an rsync 3.x client).
2169 - Added the `--skip-compress=LIST` option to override the default list of file
2170 suffixes that will not be compressed when using `--compress` (`-z`).
2172 - The daemon's default for `dont compress` was extended to include: `*.7z`
2173 `*.mp[34]` `*.mov` `*.avi` `*.ogg` `*.jpg` `*.jpeg` and the name-matching routine was also
2174 optimized to run more quickly.
2176 - The `--max-delete` option now outputs a warning if it skipped any file
2177 deletions, including a count of how many deletions were skipped. (Older
2178 versions just silently stopped deleting things.)
2180 - You may specify `--max-delete=0` to a 3.0.0 client to request that it warn
2181 about extraneous files without deleting anything. If you're not sure what
2182 version the client is, you can use the less-obvious `--max-delete=-1`, as
2183 both old and new versions will treat that as the same request (though older
2184 versions don't warn).
2186 - The `--hard-link` option now uses less memory on both the sending and
2187 receiving side for all protocol versions. For protocol 30, the use of a
2188 hashtable on the sending side allows us to more efficiently convey to the
2189 receiver what files are linked together. This reduces the amount of data
2190 sent over the socket by a considerable margin (rather than adding more
2191 data), and limits the in-memory storage of the device+inode information to
2192 just the sending side for the new protocol 30, or to the receiving side when
2193 speaking an older protocol (note that older rsync versions kept the
2194 device+inode information on both sides).
2196 - The filter rules now support a perishable (`p`) modifier that marks rules
2197 that should not have an effect in a directory that is being deleted. e.g.
2198 `-f '-p .svn/'` would only affect `live` .svn directories.
2200 - Rsync checks all the alternate-destination args for validity (e.g.
2201 `--link-dest`). This lets the user know when they specified a directory that
2204 - If we get an ENOSYS error setting the time on a symlink, we don't complain
2205 about it anymore (for those systems that even support the setting of the
2206 modify-time on a symlink).
2208 - Protocol 30 now uses MD5 checksums instead of MD4.
2210 - Changed the `--append` option to not checksum the existing data in the
2211 destination file, which speeds up file appending.
2213 - Added the `--append-verify` option, which works like the older `--append`
2214 option (verifying the existing data in the destination file). For
2215 compatibility with older rsync versions, any use of `--append` that is
2216 talking protocol 29 or older will revert to the `--append-verify` method.
2218 - Added the `--contimeout=SECONDS` option that lets the user specify a
2219 connection timeout for rsync daemon access.
2221 - Documented and extended the support for the `RSYNC_CONNECT_PROG` variable
2222 that can be used to enhance the client side of a daemon connection.
2224 - Improved the dashes and double-quotes in the nroff manpage output.
2226 - Rsync now supports a lot more `--no-OPTION` override options.
2230 - The file-list sorting algorithm now uses a sort that keeps any same-named
2231 items in the same order as they were specified. This allows rsync to always
2232 ensure that the first of the duplicates is the one that will be included in
2233 the copy. The new sort is also faster than the glibc version of qsort() and
2236 - Rsync now supports the transfer of 64-bit timestamps (`time_t` values).
2238 - Made the file-deletion code use a little less stack when recursing through a
2239 directory hierarchy of extraneous files.
2241 - Fixed a build problem with older (2.x) versions of gcc.
2243 - Added some isType() functions that make dealing with signed characters
2244 easier without forcing variables via casts.
2246 - Changed strcat/strcpy/sprintf function calls to use safer versions.
2248 - Upgraded the included popt version to 1.10.2 and improved its use of
2249 string-handling functions.
2251 - Added missing prototypes for compatibility functions from the lib dir.
2253 - Configure determines if iconv() has a const arg, allowing us to avoid a
2256 - Made the sending of some numbers more efficient for protocol 30.
2258 - Make sure that a daemon process doesn't mind if the client was weird and
2259 omitted the `--server` option.
2261 - There are more internal logging categories available in protocol 30 than the
2262 age-old FINFO and FERROR, including `FERROR_XFER` and FWARN. These new
2263 categories allow some errors and warnings to go to stderr without causing an
2264 erroneous end-of-run warning about some files not being able to be
2267 - Improved the use of `const` on pointers.
2269 - Improved J.W.'s `pool_alloc` routines to add a way of incrementally freeing
2270 older sections of a pool's memory.
2272 - The getaddrinfo.c compatibility code in the `lib` dir was replaced with some
2273 new code (derived from samba, derived from PostgreSQL) that has a better
2274 license than the old code.
2276 ### DEVELOPER RELATED:
2278 - Rsync is now licensed under the GPLv3 or later.
2280 - Rsync is now being maintained in a `git` repository instead of CVS (though
2281 the old CVS repository still exists for historical access). Several
2282 maintenance scripts were updated to work with git.
2284 - Generated files are no longer committed into the source repository. The
2285 autoconf and autoheader commands are now automatically run during the normal
2286 use of `configure` and `make`. The latest dev versions of all generated
2287 files can also be copied from the samba.org web site (see the prepare-source
2288 script's fetch option).
2290 - The `patches` directory of diff files is now built from branches in the
2291 rsync git repository (branch patch/FOO creates file patches/FOO.diff). This
2292 directory is now distributed in a separate separate tar file named
2293 rsync-patches-VERSION.tar.gz instead of the main rsync-VERSION.tar.gz.
2295 - The proto.h file is now built using a simple perl script rather than a
2296 complex awk script, which proved to be more widely compatible.
2298 - When running the tests, we now put our per-test temp dirs into a sub-
2299 directory named testtmp (which is created, if missing). This allows someone
2300 to symlink the testtmp directory to another filesystem (which is useful if
2301 the build dir's filesystem does not support ACLs and xattrs, but another
2304 - Rsync now has a way of handling protocol-version changes during the
2305 development of a new protocol version. This causes any out-of-sync versions
2306 to speak an older protocol rather than fail in a cryptic manner. This
2307 addition makes it safer to deploy a pre-release version that may interact
2308 with the public. This new exchange of sub-version info does not interfere
2309 with the `{MIN,MAX}_PROTOCOL_VERSION` checking algorithm (which does not
2310 have enough range to allow the main protocol number to be incremented for
2311 every minor tweak in that happens during development).
2313 - The csprotocol.txt file was updated to mention the daemon protocol change in
2316 ------------------------------------------------------------------------------
2318 # NEWS for rsync 2.6.9 (6 Nov 2006)
2320 ## Changes in this version:
2324 - If rsync is interrupted via a handled signal (such as SIGINT), it will once
2325 again clean-up its temp file from the destination dir.
2327 - Fixed an overzealous sanitizing bug in the handling of the `--link-dest`,
2328 `--copy-dest`, and `--compare-dest` options to a daemon without chroot: if
2329 the copy's destination dir is deeper than the top of the module's path,
2330 these options now accept a safe number of parent-dir (../) references (since
2331 these options are relative to the destination dir). The old code incorrectly
2332 chopped off all `../` prefixes for these options, no matter how deep the
2333 destination directory was in the module's hierarchy.
2335 - Fixed a bug where a deferred info/error/log message could get sent directly
2336 to the sender instead of being handled by rwrite() in the generator. This
2337 fixes an `unexpected tag 3` fatal error, and should also fix a potential
2338 problem where a deferred info/error message from the receiver might bypass
2339 the log file and get sent only to the client process. (These problems could
2340 only affect an rsync daemon that was receiving files.)
2342 - Fixed a bug when `--inplace` was combined with a `--*-dest` option and we
2343 update a file's data using an alternate basis file. The code now notices
2344 that it needs to copy the matching data from the basis file instead of
2345 (wrongly) assuming that it was already present in the file.
2347 - Fixed a bug where using `--dry-run` with a `--*-dest` option with a path
2348 relative to a directory that does not yet exist: the affected option gets
2349 its proper path value so that the output of the dry-run is right.
2351 - Fixed a bug in the %f logfile escape when receiving files: the destination
2352 path is now included in the output (e.g. you can now tell when a user
2353 specifies a subdir inside a module).
2355 - If the receiving side fails to create a directory, it will now skip trying
2356 to update everything that is inside that directory.
2358 - If `--link-dest` is specified with `--checksum` but without `--times`, rsync
2359 will now allow a hard-link to be created to a matching link-dest file even
2360 when the file's modify-time doesn't match the server's file.
2362 - The daemon now calls more timezone-using functions prior to doing a chroot.
2363 This should help some C libraries to generate proper timestamps from inside
2364 a chrooted daemon (and to not try to access /etc/timezone over and over
2367 - Fixed a bug in the handling of an absolute `--partial-dir=ABS_PATH` option:
2368 it now deletes an alternate basis file from the partial-dir that was used to
2369 successfully update a destination file.
2371 - Fixed a bug in the handling of `--delete-excluded` when using a per-dir
2372 merge file: the merge file is now honored on the receiving side, and only
2373 its unqualified include/exclude commands are ignored (just as is done for
2374 global include/excludes).
2376 - Fixed a recent bug where `--delete` was not working when transferring from
2377 the root (/) of the filesystem with `--relative` enabled.
2379 - Fixed a recent bug where an `--exclude='*'` could affect the root (/) of the
2380 filesystem with `--relative` enabled.
2382 - When `--inplace` creates a file, it is now created with owner read/write
2383 permissions (0600) instead of no permissions at all. This avoids a problem
2384 continuing a transfer that was interrupted (since `--inplace` will not
2385 update a file that has no write permissions).
2387 - If either `--remove-source-files` or `--remove-sent-files` is enabled and we
2388 are unable to remove the source file, rsync now outputs an error.
2390 - Fixed a bug in the daemon's `incoming chmod` rule: newly-created directories
2391 no longer get the 'F' (file) rules applied to them.
2393 - Fixed an infinite loop bug when a filter rule was rejected due to being
2396 - When the server receives a `--partial-dir` option from the client, it no
2397 longer runs the client-side code that adds an assumed filter rule (since the
2398 client will be sending us the rules in the usual manner, and they may have
2399 chosen to override the auto-added rule).
2403 - Added the `--log-file=FILE` and `--log-file-format=FORMAT` options. These
2404 can be used to tell any rsync to output what it is doing to a log file.
2405 They work with a client rsync, a non-daemon server rsync (see the manpage
2406 for instructions), and also allows the overriding of rsyncd.conf settings
2407 when starting a daemon.
2409 - The `--log-format` option was renamed to be `--out-format` to avoid
2410 confusing it with affecting the log-file output. (The old option remains as
2411 an alias for the new to preserve backward compatibility.)
2413 - Made `log file` and `syslog facility` settable on a per-module basis in the
2414 daemon's config file.
2416 - Added the `--remove-source-files` option as a replacement for the (now
2417 deprecated) `--remove-sent-files` option. This new option removes all
2418 non-dirs from the source directories, even if the file was already
2419 up-to-date. This fixes a problem where interrupting an rsync that was using
2420 `--remove-sent-files` and restarting it could leave behind a file that the
2421 earlier rsync synchronized, but didn't get to remove. (The deprecated
2422 `--remove-sent-files` is still understood for now, and still behaves in the
2423 same way as before.)
2425 - Added the option `--no-motd` to suppress the message-of-the-day output from
2426 a daemon when doing a copy. (See the manpage for a caveat.)
2428 - Added a new environment variable to the pre-/post-xfer exec commands (in the
2429 daemon's config file): `RSYNC_PID`. This value will be the same in both the
2430 pre- and post-xfer commands, so it can be used as a unique ID if the
2431 pre-xfer command wants to cache some arg/request info for the post-xfer
2436 - Did a code audit using IBM's code-checker program and made several changes,
2437 including: replacing most of the strcpy() and sprintf() calls with
2438 strlcpy(), snprintf(), and memcpy(), adding a 0-value to an enum that had
2439 been intermingling a literal 0 with the defined enum values, silencing some
2440 uninitialized memory checks, marking some functions with a `noreturn`
2441 attribute, and changing an `if` that could never succeed on some platforms
2442 into a pre-processor directive that conditionally compiles the code.
2444 - Fixed a potential bug in `f_name_cmp()` when both the args are a top-level
2445 `.` dir (which doesn't happen in normal operations).
2447 - Changed `exit_cleanup()` so that it can never return instead of exit. The
2448 old code might return if it found the `exit_cleanup()` function was being
2449 called recursively. The new code is segmented so that any recursive calls
2450 move on to the next step of the exit-processing.
2452 - The macro WIFEXITED(stat) will now be defined if the OS didn't already
2455 ### DEVELOPER RELATED:
2457 - The acls.diff and xattrs.diff patches have received a bunch of work to make
2458 them much closer to being acceptable in the main distribution. The xattrs
2459 patch also has some preliminary Mac OS X and FreeBSD compatibility code that
2460 various system types to exchange extended file-attributes.
2462 - A new diff in the patches dir, fake-root.diff, allows rsync to maintain a
2463 backup hierarchy with full owner, group, and device info without actually
2464 running as root. It does this using a special extended attribute, so it
2465 depends on xattrs.diff (which depends on acls.diff).
2467 - The rsync.yo and rsyncd.conf.yo files have been updated to work better with
2468 the latest yodl 2.x releases.
2470 - Updated config.guess and config.sub to their 2006-07-02 versions.
2472 - Updated various files to include the latest FSF address and to have
2473 consistent opening comments.
2475 ------------------------------------------------------------------------------
2477 # NEWS for rsync 2.6.8 (22 Apr 2006)
2479 ## Changes in this version:
2483 - Fixed a bug in the exclude code where an anchored exclude without any
2484 wildcards fails to match an absolute source arg, but only when `--relative`
2487 - Improved the I/O code for the generator to fix a potential hang when the
2488 receiver gets an EOF on the socket but the generator's select() call never
2489 indicates that the socket is writable for it to be notified about the EOF.
2490 (This can happen when using stunnel).
2492 - Fixed a problem with the file-reading code where a failed read (such as that
2493 caused by a bad sector) would not advance the file's read-position beyond
2494 the failed read's data.
2496 - Fixed a logging bug where the `log file` directive was not being honored in
2497 a single-use daemon (one spawned by a remote-shell connection or by init).
2499 - If rsync cannot honor the `--delete` option, we output an error and exit
2500 instead of silently ignoring the option.
2502 - Fixed a bug in the `--link-dest` code that prevented special files (such as
2503 fifos) from being linked.
2505 - The ability to hard-link symlinks and special files is now determined at
2506 configure time instead of at runtime. This fixes a bug with `--link-dest`
2507 creating a hard-link to a symlink's referent on a BSD system.
2511 - In daemon mode, if rsync fails to bind to the requested port, the error(s)
2512 returned by socket() and/or bind() are now logged.
2514 - When we output a fatal error, we now output the version of rsync in the
2517 - Improved the documentation for the `--owner` and `--group` options.
2519 - The rsyncstats script in `support` has an improved line-parsing regex that
2520 is easier to read and also makes it to parse syslog-generated lines.
2522 - A new script in `support`: file-attr-restore, can be used to restore the
2523 attributes of a file-set (the permissions, ownership, and group info) taken
2524 from the cached output of a `find ARG... -ls` command.
2526 ### DEVELOPER RELATED:
2528 - Removed the unused function `write_int_named()`, the unused variable
2529 `io_read_phase`, and the rarely used variable `io_write_phase`. This also
2530 elides the confusing 'phase "unknown"' part of one error message.
2532 - Removed two unused configure checks and two related (also unused)
2533 compatibility functions.
2535 - The xattrs.diff patch received a security fix that prevents a potential
2536 buffer overflow in the `receive_xattr()` code.
2538 - The acls.diff patch has been improved quite a bit, with more to come.
2540 - A new patch was added: log-file.diff. This contains an early version of a
2541 future option, `--log-file=FILE`, that will allow any rsync to log its
2542 actions to a file (something that only a daemon supports at present).
2544 ------------------------------------------------------------------------------
2546 # NEWS for rsync 2.6.7 (11 Mar 2006)
2548 ## Changes in this version:
2552 - The letter 'D' in the itemized output was being used for both devices
2553 (character or block) as well as other special files (such as fifos and named
2554 sockets). This has changed to separate non-device special files under the
2555 'S' designation (e.g. `cS+++++++ path/fifo`). See also the `--specials`
2558 - The way rsync escapes unreadable characters has changed. First, rsync now
2559 has support for recognizing valid multi-byte character sequences in your
2560 current locale, allowing it to escape fewer characters than before for a
2561 locale such as UTF-8. Second, it now uses an escape idiom of `\#123`, which
2562 is the literal string `\#` followed by exactly 3 octal digits. Rsync no
2563 longer doubles a backslash character in a filename (e.g. it used to output
2564 `foo\\bar` when copying `foo\bar`) -- now it only escapes a backslash that
2565 is followed by a hash-sign and 3 digits (0-9) (e.g. it will output
2566 `foo\#134#789` when copying `foo\#789`). See also the `--8-bit-output`
2567 (`-8`) option, mentioned below.
2569 Script writers: the local rsync is the one that outputs escaped names, so if
2570 you need to support unescaping of filenames for older rsyncs, I'd suggest
2571 that you parse the output of `rsync --version` and only use the old
2572 unescaping rules for 2.6.5 and 2.6.6.
2576 - Fixed a really old bug that caused `--checksum` (`-c`) to checksum all the
2577 files encountered during the delete scan (ouch).
2579 - Fixed a potential hang in a remote generator: when the receiver gets a
2580 read-error on the socket, it now signals the generator about this so that
2581 the generator does not try to send any of the terminating error messages to
2582 the client (avoiding a potential hang in some setups).
2584 - Made hard-links work with symlinks and devices again.
2586 - If the sender gets an early EOF reading a source file, we propagate this
2587 error to the receiver so that it can discard the file and try requesting it
2588 again (which is the existing behavior for other kinds of read errors).
2590 - If a device-file/special-file changes permissions, rsync now updates the
2591 permissions without recreating the file.
2593 - If the user specifies a remote-host for both the source and destination, we
2594 now output a syntax error rather than trying to open the destination
2595 hostspec as a filename.
2597 - When `--inplace` creates a new destination file, rsync now creates it with
2598 permissions 0600 instead of 0000 -- this makes restarting possible when the
2599 transfer gets interrupted in the middle of sending a new file.
2601 - Reject the combination of `--inplace` and `--sparse` since the sparse-output
2602 algorithm doesn't work when overwriting existing data.
2604 - Fixed the directory name in the error that is output when `pop_dir()` fails.
2606 - Really fixed the parsing of a `!` entry in .cvsignore files this time.
2608 - If the generator gets a stat() error on a file, output it (this used to
2609 require at least `-vv` for the error to be seen).
2611 - If waitpid() fails or the child rsync didn't exit cleanly, we now handle the
2612 exit status properly and generate a better error.
2614 - Fixed some glitches in the double-verbose output when using `--copy-dest`,
2615 `--link-dest`, or `--compare-dest`. Also improved how the verbose output
2616 handles hard-links (within the transfer) that had an up-to-date alternate
2617 `dest` file, and copied files (via `--copy-dest`).
2619 - Fixed the matching of the dont-compress items (e.g. `*.gz`) against files
2620 that have a path component containing a slash.
2622 - If the code reading a filter/exclude file gets an EINTR error, rsync now
2623 clears the error flag on the file handle so it can keep on reading.
2625 - If `--relative` is active, the sending side cleans up trailing `/` or `/.`
2626 suffixes to avoid triggering a bug in older rsync versions. Also, we now
2627 reject a `..` dir if it would be sent as a relative dir.
2629 - If a non-directory is in the way of a directory and rsync is run with
2630 `--dry-run` and `--delete`, rsync no longer complains about not being able
2631 to opendir() the not-yet present directory.
2633 - When `--list-only` is used and a non-existent local destination dir was also
2634 specified as a destination, rsync no longer generates a warning about being
2635 unable to create the missing directory.
2637 - Fixed some problems with `--relative --no-implied-dirs` when the destination
2638 directory did not yet exist: we can now create a symlink or device when it
2639 is the first thing in the missing dir, and `--fuzzy` no longer complains
2640 about being unable to open the missing dir.
2642 - Fixed a bug where the `--copy-links` option would not affect implied
2643 directories without `--copy-unsafe-links` (see `--relative`).
2645 - Got rid of the need for `--force` to be used in some circumstances with
2646 `--delete-after` (making it consistent with
2647 `--delete-before`/`--delete-during`).
2649 - Rsync now ignores the SIGXFSZ signal, just in case your OS sends this when a
2650 file is too large (rsync handles the write error).
2652 - Fixed a bug in the Proxy-Authorization header's base64-encoded value: it was
2653 not properly padded with trailing '=' chars. This only affects a user that
2654 need to use a password-authenticated proxy for an outgoing daemon-rsync
2657 - If we're transferring an empty directory to a new name, rsync no longer
2658 forces `S_IWUSR` if it wasn't already set, nor does it accidentally leave it
2661 - Fixed a bug in the debug output (`-vvvvv`) that could mention the wrong
2662 checksum for the current file offset.
2664 - Rsync no longer allows a single directory to be copied over a non-directory
2669 - Added the `--append` option that makes rsync append data onto files that are
2670 longer on the source than the destination (this includes new files).
2672 - Added the `--min-size=SIZE` option to exclude small files from the transfer.
2674 - Added the `--compress-level` option to allow you to set how aggressive
2675 rsync's compression should be (this option implies `--compress`).
2677 - Enhanced the parsing of the SIZE value for `--min-size` and `--max-size` to
2678 allow easy entry of multiples of 1000 (instead of just multiples of 1024)
2679 and off-by-one values too (e.g. `--max-size=8mb-1`).
2681 - Added the `--8-bit-output` (`-8`) option, which tells rsync to avoid
2682 escaping high-bit characters that it thinks are unreadable in the current
2685 - The new option `--human-readable` (`-h`) changes the output of `--progress`,
2686 `--stats`, and the end-of-run summary to be easier to read. If repeated, the
2687 units become powers of 1024 instead of powers of 1000. (The old meaning of
2688 `-h`, as a shorthand for `--help`, still works as long as you just use it on
2689 its own, as in `rsync -h`.)
2691 - If lutimes() and/or lchmod() are around, use them to allow the preservation
2692 of attributes on symlinks.
2694 - The `--link-dest` option now affects symlinks and devices (when possible).
2696 - Added two config items to the rsyncd.conf parsing: `pre-xfer exec` and
2697 `post-xfer exec`. These allow a command to be specified on a per-module
2698 basis that will be run before and/or after a daemon-mode transfer. (See the
2699 manpage for a list of the environment variables that are set with
2700 information about the transfer.)
2702 - When using the `--relative` option, you can now insert a dot dir in the
2703 source path to indicate where the replication of the source dirs should
2704 start. For example, if you specify a source path of
2705 rsync://host/module/foo/bar/./baz/dir with `-R`, rsync will now only
2706 replicate the `baz/dir` part of the source path (note: a trailing dot dir is
2707 unaffected unless it also has a trailing slash).
2709 - Added some new `--no-FOO` options that make it easier to override unwanted
2710 implied or default options. For example, `-a --no-o` (aka `--archive
2711 --no-owner`) can be used to turn off the preservation of file ownership that
2714 - Added the `--chmod=MODE` option that allows the destination permissions to
2715 be changed from the source permissions. E.g. `--chmod=g+w,o-rwx`
2717 - Added the `incoming chmod` and `outgoing chmod` daemon options that allow a
2718 module to specify what permissions changes should be applied to all files
2719 copied to and from the daemon.
2721 - Allow the `--temp-dir` option to be specified when starting a daemon, which
2722 sets the default temporary directory for incoming files.
2724 - If `--delete` is combined with `--dirs` without `--recursive`, rsync will
2725 now delete in any directory whose content is being synchronized.
2727 - If `--backup` is combined with `--delete` without `--backup-dir` (and
2728 without `--delete-excluded`), we add a `protect` filter-rule to ensure that
2729 files with the backup suffix are not deleted.
2731 - The file-count stats that are output by `--progress` were improved to better
2732 indicate what the numbers mean. For instance, the output: `(xfer#5,
2733 to-check=8383/9999)` indicates that this was the fifth file to be
2734 transferred, and we still need to check 8383 more files out of a total of
2737 - The include/exclude code now allows a `dir/***` directive (with 3 trailing
2738 stars) to match both the dir itself as well as all the content below the dir
2739 (`dir/**` would not match the dir).
2741 - Added the `--prune-empty-dirs` (`-m`) option that makes the receiving rsync
2742 discard empty chains of directories from the file-list. This makes it easier
2743 to selectively copy files from a source hierarchy and end up with just the
2744 directories needed to hold the resulting files.
2746 - If the `--itemize-changes` (`-i`) option is repeated, rsync now includes
2747 unchanged files in the itemized output (similar to `-vv`, but without all
2748 the other verbose messages that can get in the way). Of course, the client
2749 must be version 2.6.7 for this to work, but the remote rsync only needs to
2750 be 2.6.7 if you're pushing files.
2752 - Added the `--specials` option to tell rsync to copy non-device special files
2753 (which rsync now attempts even as a normal user). The `--devices` option now
2754 requests the copying of just devices (character and block). The `-D` option
2755 still requests both (e.g. `--devices` and `--specials`), `-a` still implies
2756 `-D`, and non-root users still get a silent downgrade that omits device
2759 - Added the `--super` option to make the receiver always attempt super-user
2760 activities. This is useful for systems that allow things such as devices to
2761 be created or ownership to be set without being UID 0, and is also useful
2762 for someone who wants to ensure that errors will be output if the receiving
2763 rsync isn't being run as root.
2765 - Added the `--sockopts` option for those few who want to customize the TCP
2766 options used to contact a daemon rsync.
2768 - Added a way for the `--temp-dir` option to be combined with a partial-dir
2769 setting that lets rsync avoid non-atomic updates (for those times when
2770 `--temp-dir` is not being used because space is tight).
2772 - A new support script, files-to-excludes, will transform a list of files into
2773 a set of include/exclude directives that will copy those files.
2775 - A new option, `--executability` (`-E`) can be used to preserve just the
2776 execute bit on files, for those times when using the `--perms` option is not
2779 - The daemon now logs each connection and also each module-list request that
2782 - New log-format options: %M (modtime), %U (uid), %G (gid), and %B (permission
2783 bits, e.g. `rwxr-xrwt`).
2785 - The `--dry-run` option no longer forces the enabling of `--verbose`.
2787 - The `--remove-sent-files` option now does a better job of incrementally
2788 removing the sent files on the sending side (older versions tended to clump
2789 up all the removals at the end).
2791 - A daemon now supersedes its minimal SIGCHLD handler with the standard
2792 PID-remembering version after forking. This ensures that the generator can
2793 get the child-exit status from the receiver.
2795 - Use of the `--bwlimit` option no longer interferes with the remote rsync
2796 sending error messages about invalid/refused options.
2798 - Rsync no longer returns a usage error when used with one local source arg
2799 and no destination: this now implies the `--list-only` option, just like the
2800 comparable situation with a remote source arg.
2802 - Added the `--copy-dirlinks` option, a more limited version of
2805 - Various documentation improvements, including: a better synopsis, some
2806 improved examples, a better discussion of the presence and absence of
2807 `--perms` (including how it interacts with the new `--executability` and
2808 `--chmod` options), an extended discussion of `--temp-dir`, an improved
2809 discussion of `--partial-dir`, a better description of rsync's pattern
2810 matching characters, an improved `--no-implied-dirs` section, and the
2811 documenting of what the `--stats` option outputs.
2813 - Various new and updated diffs in the patches dir, including: acls.diff,
2814 xattrs.diff, atimes.diff, detect-renamed.diff, and slp.diff.
2818 - We now use sigaction() and sigprocmask() if possible, and fall back on
2819 signal() if not. Using sigprocmask() ensures that rsync enables all the
2820 signals that it needs, just in case it was started in a masked state.
2822 - Some buffer sizes were expanded a bit, particularly on systems where
2823 MAXPATHLEN is overly small (e.g. Cygwin).
2825 - If `io_printf()` tries to format more data than fits in the buffer, exit
2826 with an error instead of transmitting a truncated buffer.
2828 - If a `va_copy` macro is defined, lib/snprintf.c will use it when defining
2829 the `VA_COPY` macro.
2831 - Reduced the amount of stack memory needed for each level of directory
2832 recursion by nearly MAXPATHLEN bytes.
2834 - The wildmatch function was extended to allow an array of strings to be
2835 supplied as the string to match. This allows the exclude code to do less
2838 - Got rid of the `safe_fname()` function (and all the myriad calls) and
2839 replaced it with a new function in the log.c code that filters all the
2840 output going to the terminal.
2842 - Unified the `f_name()` and the `f_name_to()` functions.
2844 - Improved the hash-table code the sender uses to handle checksums to make it
2845 use slightly less memory and run just a little faster.
2847 ### DEVELOPER RELATED:
2849 - The diffs in the patches dir now require `patch -p1 <DIFF` instead of the
2850 previous `-p0`. Also, the version included in the release tar now affect
2851 generated files (e.g. configure, rsync.1, proto.h, etc.), so it is no longer
2852 necessary to run autoconf and/or yodl unless you're applying a patch that
2853 was checked out from CVS.
2855 - Several diffs in the patches dir now use the proper `--enable-FOO` configure
2856 option instead of `--with-FOO` to turn on the inclusion of the newly patched
2859 - There is a new script, `prepare-source` than can be used to update the
2860 various generated files (proto.h, configure, etc.) even before configure has
2861 created the Makefile (this is mainly useful when patching the source with a
2862 patch that doesn't affect generated files).
2864 - The testsuite now sets HOME so that it won't be affected by a file such as
2867 ------------------------------------------------------------------------------
2869 # NEWS for rsync 2.6.6 (28 Jul 2005)
2871 ## Changes in this version:
2875 - The zlib code was upgraded to version 1.2.3 in order to make it more secure.
2876 While the widely-publicized security problem in zlib 1.2.2 did not affect
2877 rsync, another security problem surfaced that affects rsync's zlib 1.1.4.
2881 - The setting of `flist->high` in `clean_flist()` was wrong for an empty list.
2882 This could cause `flist_find()` to crash in certain rare circumstances (e.g.
2883 if just the right directory setup was around when `--fuzzy` was combined
2884 with `--link-dest`).
2886 - The outputting of hard-linked files when verbosity was > 1 was not right:
2887 (1) Without `-i` it would output the name of each hard-linked file as though
2888 it had been changed; it now outputs a `is hard linked` message for the file.
2889 (2) With `-i` it would output all dots for the unchanged attributes of a
2890 hard-link; it now changes those dots to spaces, as is done for other totally
2893 - When backing up a changed symlink or device, get rid of any old backup item
2894 so that we don't get an `already exists` error.
2896 - A couple places that were comparing a local and a remote modification-time
2897 were not honoring the `--modify-window` option.
2899 - Fixed a bug where the 'p' (permissions) itemized-changes flag might get set
2900 too often (if some non-significant mode bits differed).
2902 - Fixed a really old, minor bug that could cause rsync to warn about being
2903 unable to mkdir() a path that ends in `/.` because it just created the
2904 directory (required `--relative`, `--no-implied-dirs`, a source path that
2905 ended in either a trailing slash or a trailing `/.`, and a non-existing
2906 destination dir to tickle the bug in a recent version).
2910 - Made the `max verbosity` setting in the rsyncd.conf file settable on a
2911 per-module basis (which now matches the documentation).
2913 - The rrsync script has been upgraded to verify the args of options that take
2914 args (instead of rejecting any such options). It was also changed to try to
2915 be more secure and to fix a problem in the parsing of a pull operation that
2916 has multiple source args. (See the support dir.)
2918 - Improved the documentation that explains the difference between a normal
2919 daemon transfer and a daemon-over remote-shell transfer.
2921 - Some of the diffs supplied in the patches dir were fixed and/or improved.
2925 - Made configure define `NOBODY_USER` (currently hard-wired to `nobody`) and
2926 `NOBODY_GROUP` (set to either `nobody` or `nogroup` depending on what we
2927 find in the /etc/group file).
2929 - Added a test to the test suite, itemized.test, that tests the output of `-i`
2930 (log-format w/%i) and some double-verbose messages.
2932 ------------------------------------------------------------------------------
2934 # NEWS for rsync 2.6.5 (1 Jun 2005)
2936 ## Changes in this version:
2940 - Non-printable chars in filenames are now output using backslash-escaped
2941 characters rather than '?'s. Any non-printable character is output using 3
2942 digits of octal (e.g. `\n` -> `\012`), and a backslash is now output as
2943 `\\`. Rsync also uses your locale setting, which can make it treat fewer
2944 high-bit characters as non-printable.
2946 - If rsync received an empty file-list when pulling files, it would output a
2947 `nothing to do` message and exit with a 0 (success) exit status, even if the
2948 remote rsync returned an error (it did not do this under the same conditions
2949 when pushing files). This was changed to make the pulling behavior the same
2950 as the pushing behavior: we now do the normal end-of-run outputting
2951 (depending on options) and exit with the appropriate exit status.
2955 - A crash bug was fixed when a daemon had its `path` set to `/`, did not have
2956 chroot enabled, and used some anchored excludes in the rsyncd.conf file.
2958 - Fixed a bug in the transfer of a single file when `-H` is specified (rsync
2959 would either infinite loop or perhaps crash).
2961 - Fixed a case where the generator might try (and fail) to tweak the
2962 write-permissions of a read-only directory in list-only mode (this only
2963 caused an annoying warning message).
2965 - If `--compare-dest` or `--link-dest` uses a locally-copied file as the basis
2966 for an updated version, log this better when `--verbose` or `-i` is in
2969 - Fixed the accidental disabling of `--backup` during the `--delete-after`
2972 - Restored the ability to use the `--address` option in client mode (in
2973 addition to its use in daemon mode).
2975 - Make sure that some temporary progress information from the delete
2976 processing does not get left on the screen when it is followed by a newline.
2978 - When `--existing` skips a directory with extra verbosity, refer to it as a
2979 `directory`, not a `file`.
2981 - When transferring a single file to a different-named file, any generator
2982 messages that are source-file related no longer refer to the file by the
2983 destination filename.
2985 - Fixed a bug where hard-linking a group of files might fail if the generator
2986 hasn't created a needed destination directory yet.
2988 - Fixed a bug where a hard-linked group of files that is newly-linked to a
2989 file in a `--link-dest` dir doesn't link the files from the rest of the
2992 - When deleting files with the `--one-file-system` (`-x`) option set, rsync no
2993 longer tries to remove files from inside a mount-point on the receiving
2994 side. Also, we don't complain about being unable to remove the mount-point
2997 - Fixed a compatibility problem when using `--cvs-ignore` (`-C`) and sending
2998 files to an older rsync without using `--delete`.
3000 - Make sure that a `- !` or `+ !` include/exclude pattern does not trigger the
3001 list-clearing action that is reserved for `!`.
3003 - Avoid a timeout in the generator when the sender/receiver aren't handling
3004 the generator's checksum output quickly enough.
3006 - Fixed the omission of some directories in the delete processing when
3007 `--relative` (`-R`) was combined with a source path that had a trailing
3010 - Fixed a case where rsync would erroneously delete some files and then
3011 re-transfer them when the options `--relative` (`-R`) and `--recursive`
3012 (`-r`) were both enabled (along with `--delete`) and a source path had a
3015 - Make sure that `--max-size` doesn't affect a device or a symlink.
3017 - Make sure that a system with a really small MAXPATHLEN does not cause the
3018 buffers in `readfd_unbuffered()` to be too small to receive normal messages.
3019 (This mainly affected Cygwin.)
3021 - If a source pathname ends with a filename of `..`, treat it as if `../` had
3022 been specified (so that we don't copy files to the parent dir of the
3025 - If `--delete` is combined with a file-listing rsync command (i.e. no
3026 transfer is happening), avoid outputting a warning that we couldn't delete
3029 - If `--stats` is specified with `--delete-after`, ensure that all the
3030 `deleting` messages are output before the statistics.
3032 - Improved one `if` in the deletion code that was only checking errno for
3033 ENOTEMPTY when it should have also been checking for EEXIST (for
3034 compatibility with OS variations).
3038 - Added the `--only-write-batch=FILE` option that may be used (instead of
3039 `--write-batch=FILE`) to create a batch file without doing any actual
3040 updating of the destination. This allows you to divert all the file-updating
3041 data away from a slow data link (as long as you are pushing the data to the
3042 remote server when creating the batch).
3044 - When the generator is taking a long time to fill up its output buffer (e.g.
3045 if the transferred files are few, small, or missing), it now periodically
3046 flushes the output buffer so that the sender/receiver can get started on the
3047 files sooner rather than later.
3049 - Improved the keep-alive code to handle a long silence between the sender and
3050 the receiver that can occur when the sender is receiving the checksum data
3053 - Improved the auth-errors that are logged by the daemon to include some
3054 information on why the authorization failed: wrong user, password mismatch,
3055 etc. (The client-visible message is unchanged!)
3057 - Improved the client's handling of an `@ERROR` from a daemon so that it does
3058 not complain about an unexpectedly closed socket (since we really did expect
3059 the socket to close).
3061 - If the daemon can't open the log-file specified in rsyncd.conf, fall back to
3062 using syslog and log an appropriate warning. This is better than what was
3063 typically a totally silent (and fatal) failure (since a daemon is not
3064 usually run with the `--no-detach` option that was necessary to see the
3067 - The manpages now consistently refer to an rsync daemon as a `daemon`
3068 instead of a `server` (to distinguish it from the server process in a
3069 non-daemon transfer).
3071 - Made a small change to the rrsync script (restricted rsync -- in the support
3072 dir) to make a read-only server reject all `--remove-*` options when sending
3073 files (to future-proof it against the possibility of other similar options
3074 being added at some point).
3078 - Rsync now calls `setlocale(LC_CTYPE, "")`. This enables isprint() to better
3079 discern which filename characters need to be escaped in messages (which
3080 should result in fewer escaped characters in some locales).
3082 - Improved the naming of the log-file open/reopen/close functions.
3084 - Removed some protocol-compatibility code that was only needed to help
3085 someone running a pre-release of 2.6.4.
3089 - Added configure option `--disable-locale` to disable any use of setlocale()
3092 - Fixed a bug in the `SUPPORT{,_HARD}_LINKS` #defines which prevented rsync
3093 from being built without symlink or hard-link support.
3095 - Only #define `HAVE_REMSH` if it is going to be set to 1.
3097 - Configure now disables the use of mkstemp() under HP-UX (since they refuse
3098 to fix its broken handling of large files).
3100 - Configure now explicitly checks for the lseek64() function so that the code
3101 can use `HAVE_LSEEK64` instead of inferring lseek64()'s presence based on
3102 the presence of the `off64_t` type.
3104 - Configure no longer mentions the change in the default remote-shell (from
3105 rsh to ssh) that occurred for the 2.6.0 release.
3107 - Some minor enhancements to the test scripts.
3109 - Added a few new `*.diff` files to the patches dir, including a patch that
3110 enables the optional copying of extended attributes.
3112 ------------------------------------------------------------------------------
3114 # NEWS for rsync 2.6.4 (30 March 2005)
3116 ## Changes in this version:
3118 ### PROTOCOL NUMBER:
3120 - The protocol number was changed to 29.
3124 - When rsync deletes a directory and outputs a verbose message about it, it
3125 now appends a trailing slash to the name instead of (only sometimes)
3126 outputting a preceding "directory " string.
3128 - The `--stats` output will contain file-list time-statistics if both sides
3129 are 2.6.4, or if the local side is 2.6.4 and the files are being pushed
3130 (since the stats come from the sending side). (Requires protocol 29 for a
3133 - The `%o` (operation) log-format escape now has a third value (besides `send`
3134 and `recv`): `del.` (with trailing dot to make it 4 chars). This changes
3135 the way deletions are logged in the daemon's log file.
3137 - When the `--log-format` option is combined with `--verbose`, rsync now
3138 avoids outputting the name of the file twice in most circumstances. As long
3139 as the `--log-format` item does not refer to any post-transfer items (such
3140 as %b or %c), the `--log-format` message is output prior to the transfer, so
3141 `--verbose` is now the equivalent of a `--log-format` of '%n%L' (which
3142 outputs the name and any link info). If the log output must occur after the
3143 transfer to be complete, the only time the name is also output prior to the
3144 transfer is when `--progress` was specified (so that the name will precede
3145 the progress stats, and the full `--log-format` output will come after).
3147 - Non-printable characters in filenames are replaced with a '?' to avoid
3148 corrupting the screen or generating empty lines in the output.
3152 - Restore the list-clearing behavior of `!` in a .cvsignore file (2.6.3 was
3153 only treating it as a special token in an rsync include/exclude file).
3155 - The combination of `--verbose` and `--dry-run` now mentions the full list of
3156 changes that would be output without `--dry-run`.
3158 - Avoid a mkdir warning when removing a directory in the destination that
3159 already exists in the `--backup-dir`.
3161 - An OS that has a binary mode for its files (such as Cygwin) needed
3162 `setmode(fd, O_BINARY)` called on the temp-file we opened with mkstemp().
3163 (Fix derived from Cygwin's 2.6.3 rsync package.)
3165 - Fixed a potential hang when verbosity is high, the client side is the
3166 sender, and the file-list is large.
3168 - Fixed a potential protocol-corrupting bug where the generator could merge a
3169 message from the receiver into the middle of a multiplexed packet of data if
3170 only part of that data had been written out to the socket when the message
3171 from the generator arrived.
3173 - We now check if the OS doesn't support using mknod() for creating FIFOs and
3174 sockets, and compile-in some compatibility code using mkfifo() and socket()
3177 - Fixed an off-by-one error in the handling of `--max-delete=N`. Also, if the
3178 `--max-delete` limit is exceeded during a run, we now output a warning about
3179 this at the end of the run and exit with a new error code (25).
3181 - One place in the code wasn't checking if fork() failed.
3183 - The `ignore nonreadable` daemon parameter used to erroneously affect
3184 readable symlinks that pointed to a non-existent file.
3186 - If the OS does not have lchown() and a chown() of a symlink will affect the
3187 referent of a symlink (as it should), we no longer try to set the user and
3190 - The generator now properly runs the hard-link loop and the dir-time
3191 rewriting loop after we're sure that the redo phase is complete.
3193 - When `--backup` was specified with `--partial-dir=DIR`, where DIR is a
3194 relative path, the backup code was erroneously trying to backup a file that
3195 was put into the partial-dir.
3197 - If a file gets resent in a single transfer and the `--backup` option is
3198 enabled along with `--inplace`, rsync no longer performs a duplicate backup
3199 (it used to overwrite the first backup with the failed file).
3201 - One call to `flush_write_file()` was not being checked for an error.
3203 - The `--no-relative` option was not being sent from the client to a server
3206 - If an rsync daemon specified `dont compress = ...` for a file and the client
3207 tried to specify `--compress`, the libz code was not handling a compression
3208 level of 0 properly. This could cause a transfer failure if the block-size
3209 for a file was large enough (e.g. rsync might have exited with an error for
3212 - Fixed a bug that would sometimes surface when using `--compress` and sending
3213 a file with a block-size larger than 64K (either manually specified, or
3214 computed due to the file being really large). Prior versions of rsync would
3215 sometimes fail to decompress the data properly, and thus the transferred
3216 file would fail its verification.
3218 - If a daemon can't open the specified log file (i.e. syslog is not being
3219 used), die without crashing. We also output an error about the failure on
3220 stderr (which will only be seen if `--no-detach` was specified) and exit
3221 with a new error code (6).
3223 - A local transfer no longer duplicates all its include/exclude options (since
3224 the forked process already has a copy of the exclude list, there's no need
3225 to send them a set of duplicates).
3227 - The output of the items that are being updated by the generator (dirs,
3228 symlinks, devices) is now intermingled in the proper order with the output
3229 from the items that the receiver is updating (regular files) when pulling.
3230 This misordering was particularly bad when `--progress` was specified.
3231 (Requires protocol 29.)
3233 - When `--timeout` is specified, lulls that occur in the transfer while the
3234 generator is doing work that does not generate socket traffic (looking for
3235 changed files, deleting files, doing directory-time touch-ups, etc.) will
3236 cause a new keep-alive packet to be sent that should keep the transfer going
3237 as long as the generator continues to make progress. (Requires protocol 29.)
3239 - The stat size of a device is not added to the total file size of the items
3240 in the transfer (the size might be undefined on some OSes).
3242 - Fixed a problem with refused-option messages sometimes not making it back to
3243 the client side when a remote `--files-from` was in effect and the daemon
3246 - The `--compare-dest` option was not updating a file that differed in (the
3247 preserved) attributes from the version in the compare-dest DIR.
3249 - When rsync is copying files into a write-protected directory, fixed the
3250 change-report output for the directory so that we don't report an identical
3251 directory as changed.
3255 - Rsync now supports popt's option aliases, which means that you can use
3256 /etc/popt and/or ~/.popt to create your own option aliases.
3258 - Added the `--delete-during` (`--del`) option which will delete files from
3259 the receiving side incrementally as each directory in the transfer is being
3260 processed. This makes it more efficient than the default,
3261 before-the-transfer behavior, which is now also available as
3262 `--delete-before` (and is still the default `--delete-WHEN` option that will
3263 be chosen if `--delete` or `--delete-excluded` is specified without a
3264 `--delete-WHEN` choice). All the `--del*` options infer `--delete`, so an
3265 rsync daemon that refuses `delete` will still refuse to allow any
3266 file-deleting options (including the new `--remove-sent-files` option).
3268 - All the `--delete-WHEN` options are now more memory efficient: Previously an
3269 duplicate set of file-list objects was created on the receiving side for the
3270 entire destination hierarchy. The new algorithm only creates one directory
3271 of objects at a time (for files inside the transfer).
3273 - Added the `--copy-dest` option, which works like `--link-dest` except that
3274 it locally copies identical files instead of hard-linking them.
3276 - Added support for specifying multiple `--compare-dest`, `--copy-dest`, or
3277 `--link-dest` options, but only of a single type. (Promoted from the patches
3278 dir and enhanced.) (Requires protocol 29.)
3280 - Added the `--max-size` option. (Promoted from the patches dir.)
3282 - The daemon-mode options are now separated from the normal rsync options so
3283 that they can't be mixed together. This makes it impossible to start a
3284 daemon that has improper default option values (which could cause problems
3285 when a client connects, such as hanging or crashing).
3287 - The `--bwlimit` option may now be used in combination with `--daemon` to
3288 specify both a default value for the daemon side and a value that cannot be
3289 exceeded by a user-specified `--bwlimit` option.
3291 - Added the `port` parameter to the rsyncd.conf file. (Promoted from the
3292 patches dir.) Also added `address`. The command-line options take precedence
3293 over a config-file option, as expected.
3295 - In `_exit_cleanup()`: when we are exiting with a partially-received file, we
3296 now flush any data in the write-cache before closing the partial file.
3298 - The `--inplace` support was enhanced to work with `--compare-dest`,
3299 `--link-dest`, and (the new) `--copy-dest` options. (Requires protocol 29.)
3301 - Added the `--dirs` (`-d`) option for an easier way to copy directories
3302 without recursion. Any directories that are encountered are created on the
3303 destination. Specifying a directory with a trailing slash copies its
3304 immediate contents to the destination.
3306 - The `--files-from` option now implies `--dirs` (`-d`).
3308 - Added the `--list-only` option, which is mainly a way for the client to put
3309 the server into listing mode without needing to resort to any internal
3310 option kluges (e.g. the age-old use of `-r --exclude='/*/*'` for a
3311 non-recursive listing). This option is used automatically (behind the
3312 scenes) when a modern rsync speaks to a modern daemon, but may also be
3313 specified manually if you want to force the use of the `--list-only` option
3314 over a remote-shell connection.
3316 - Added the `--omit-dir-times` (`-O`) option, which will avoid updating the
3317 modified time for directories when `--times` was specified. This option will
3318 avoid an extra pass through the file-list at the end of the transfer (to
3319 tweak all the directory times), which may provide an appreciable speedup for
3320 a really large transfer. (Promoted from the patches dir.)
3322 - Added the `--filter` (`-f`) option and its helper option, `-F`. Filter rules
3323 are an extension to the existing include/exclude handling that also supports
3324 nested filter files as well as per-directory filter files (like .cvsignore,
3325 but with full filter-rule parsing). This new option was chosen in order to
3326 ensure that all existing include/exclude processing remained 100% compatible
3327 with older versions. Protocol 29 is needed for full filter-rule support, but
3328 backward-compatible rules work with earlier protocol versions. (Promoted
3329 from the patches dir and enhanced.)
3331 - Added the `--delay-updates` option that puts all updated files into a
3332 temporary directory (by default `.~tmp~`, but settable via the
3333 `--partial-dir=DIR` option) until the end of the transfer. This makes the
3334 updates a little more atomic for a large transfer.
3336 - If rsync is put into the background, any output from `--progress` is
3339 - Documented the `max verbosity` setting for rsyncd.conf. (This setting was
3340 added a couple releases ago, but left undocumented.)
3342 - The sender and the generator now double-check the file-list index they are
3343 given, and refuse to try to do a file transfer on a non-file index (since
3344 that would indicate that something had gone very wrong).
3346 - Added the `--itemize-changes` (`-i`) option, which is a way to output a more
3347 detailed list of what files changed and in what way. The effect is the same
3348 as specifying a `--log-format` of `%i %n%L` (see both the rsync and
3349 rsyncd.conf manpages). Works with `--dry-run` too.
3351 - Added the `--fuzzy` (`-y`) option, which attempts to find a basis file for a
3352 file that is being created from scratch. The current algorithm only looks in
3353 the destination directory for the created file, but it does attempt to find
3354 a match based on size/mod-time (in case the file was renamed with no other
3355 changes) as well as based on a fuzzy name-matching algorithm. This option
3356 requires protocol 29 because it needs the new file-sorting order. (Promoted
3357 from patches dir and enhanced.) (Requires protocol 29.)
3359 - Added the `--remove-sent-files` option, which lets you move files between
3362 - The hostname in HOST:PATH or HOST::PATH may now be an IPv6 literal enclosed
3363 in '[' and ']' (e.g. `[::1]`). (We already allowed IPv6 literals in the
3364 rsync://HOST:PORT/PATH format.)
3366 - When rsync recurses to build the file list, it no longer keeps open one or
3367 more directory handles from the dir's parent dirs.
3369 - When building under windows, the default for `--daemon` is now to avoid
3370 detaching, requiring the new `--detach` option to force rsync to detach.
3372 - The `--dry-run` option can now be combined with either `--write-batch` or
3373 `--read-batch`, allowing you to run a do-nothing test command to see what
3374 would happen without `--dry-run`.
3376 - The daemon's `read only` config item now sets an internal `read_only`
3377 variable that makes extra sure that no write/delete calls on the read-only
3380 - The log-format % escapes can now have a numeric field width in between the %
3381 and the escape letter (e.g. `%-40n %08p`).
3383 - Improved the option descriptions in the `--help` text.
3387 - Added atomic-rsync to the support dir: a perl script that will transfer some
3388 files using rsync, and then move the updated files into place all at once at
3389 the end of the transfer. Only works when pulling, and uses `--link-dest` and
3390 a parallel hierarchy of files to effect its update.
3392 - Added mnt-excl to the support dir: a perl script that takes the /proc/mounts
3393 file and translates it into a set of excludes that will exclude all mount
3394 points (even mapped mounts to the same disk). The excludes are made relative
3395 to the specified source dir and properly anchored.
3397 - Added savetransfer.c to the support dir: a C program that can make a copy of
3398 all the data that flows over the wire. This lets you test for data
3399 corruption (by saving the data on both the sending side and the receiving
3400 side) and provides one way to debug a protocol error.
3402 - Added rrsync to the support dir: this is an updated version of Joe Smith's
3403 restricted rsync perl script. This helps to ensure that only certain rsync
3404 commands can be run by an ssh invocation.
3408 - Added better checking of the checksum-header values that come over the
3411 - Merged a variety of file-deleting functions into a single function so that
3412 it is easier to maintain.
3414 - Improved the type of some variables (particularly blocksize vars) for
3415 consistency and proper size.
3417 - Got rid of the uint64 type (which we didn't need).
3419 - Use a slightly more compatible set of core #include directives.
3421 - Defined int32 in a way that ensures that the build dies if we can't find a
3422 variable with at least 32 bits.
3424 ### PROTOCOL DIFFERENCES FOR VERSION 29:
3426 - A 16-bit flag-word is transmitted after every file-list index. This
3427 indicates what is changing between the sender and the receiver. The
3428 generator now transmits an index and a flag-word to indicate when dirs and
3429 symlinks have changed (instead of producing a message), which makes the
3430 outputting of the information more consistent and less prone to screen
3431 corruption (because the local receiver/sender is now outputting all the
3432 file-change info messages).
3434 - If a file is being hard-linked, the `ITEM_XNAME_FOLLOWS` bit is enabled in
3435 the flag-word and the name of the file that was linked immediately follows
3436 in vstring format (see below).
3438 - If a file is being transferred with an alternate-basis file, the
3439 `ITEM_BASIS_TYPE_FOLLOWS` bit is enabled in the flag-word and a single byte
3440 follows, indicating what type of basis file was chosen. If that indicates
3441 that a fuzzy-match was selected, the `ITEM_XNAME_FOLLOWS` bit is set in the
3442 flag-word and the name of the match in vstring format follows the basis
3443 byte. A vstring is a variable length string that has its size written prior
3444 to the string, and no terminating null. If the string is from 1-127 bytes,
3445 the length is a single byte. If it is from 128-32767 bytes, the length is
3446 written as ((len >> 8) | 0x80) followed by (len % 0x100).
3448 - The sending of exclude names is done using filter-rule syntax. This means
3449 that all names have a prefixed rule indicator, even excludes (which used to
3450 be sent as a bare pattern, when possible). The `-C` option will include the
3451 per-dir .cvsignore merge file in the list of filter rules so it is
3452 positioned correctly (unlike in some older transfer scenarios).
3454 - Rsync sorts the filename list in a different way: it sorts the subdir names
3455 after the non-subdir names for each dir's contents, and it always puts a
3456 dir's contents immediately after the dir's name in the list. (Previously an
3457 item named `foo.txt` would sort in between directory `foo/` and `foo/bar`.)
3459 - When talking to a protocol 29 rsync daemon, a list-only request is able to
3460 note this before the options are sent over the wire and the new
3461 `--list-only` option is included in the options.
3463 - When the `--stats` bytes are sent over the wire (or stored in a batch), they
3464 now include two elapsed-time values: one for how long it took to build the
3465 file-list, and one for how long it took to send it over the wire (each
3466 expressed in thousandths of a second).
3468 - When `--delete-excluded` is specified with some filter rules (AKA excludes),
3469 a client sender will now initiate a send of the rules to the receiver (older
3470 protocols used to omit the sending of excludes in this situation since there
3471 were no receiver-specific rules that survived `--delete-excluded` back
3472 then). Note that, as with all the filter-list sending, only items that are
3473 significant to the other side will actually be sent over the wire, so the
3474 filter-rule list that is sent in this scenario is often empty.
3476 - An index equal to the file-list count is sent as a keep-alive packet from
3477 the generator to the sender, which then forwards it on to the receiver. This
3478 normally invalid index is only a valid keep-alive packet if the 16-bit
3479 flag-word that follows it contains a single bit (`ITEM_IS_NEW`, which is
3480 normally an illegal flag to appear alone).
3482 - A protocol-29 batch file includes a bit for the setting of the `--dirs`
3483 option and for the setting of the `--compress` option. Also, the shell
3484 script created by `--write-batch` will use the `--filter` option instead of
3485 `--exclude-from` to capture any filter rules.
3489 - Handle an operating system that use mkdev() in place of makedev().
3491 - Improved configure to better handle cross-compiling.
3493 ------------------------------------------------------------------------------
3495 # NEWS for rsync 2.6.3 (30 Sep 2004)
3497 ## Changes in this version:
3501 - A bug in the `sanitize_path` routine (which affects a non-chrooted rsync
3502 daemon) could allow a user to craft a pathname that would get transformed
3503 into an absolute path for certain options (but not for file-transfer names).
3504 If you're running an rsync daemon with chroot disabled, **please upgrade**,
3505 ESPECIALLY if the user privs you run rsync under is anything above `nobody`.
3507 OUTPUT CHANGES (ATTN: those using a script to parse the verbose output):
3509 - Please note that the 2-line footer (output when verbose) now uses the term
3510 `sent` instead of `wrote` and `received` instead of `read`. If you are not
3511 parsing the numeric values out of this footer, a script would be better off
3512 using the empty line prior to the footer as the indicator that the verbose
3515 - The output from the `--stats` option was similarly affected to change
3516 `written` to `sent` and `read` to `received`.
3518 - Rsync ensures that a filename that contains a newline gets mentioned with
3519 each newline transformed into a question mark (which prevents a filename
3520 from causing an empty line to be output).
3522 - The `backed up ...` message that is output when at least 2 `--verbose`
3523 options are specified is now the same both with and without the
3524 `--backup-dir` option.
3528 - Fixed a crash bug that might appear when `--delete` was used and multiple
3529 source directories were specified.
3531 - Fixed a 32-bit truncation of the file length when generating the checksums.
3533 - The `--backup` code no longer attempts to create some directories over and
3534 over again (generating warnings along the way).
3536 - Fixed a bug in the reading of the secrets file (by the daemon) and the
3537 password file (by the client): the files no longer need to be terminated by
3538 a newline for their content to be read in.
3540 - If a file has a read error on the sending side or the reconstructed data
3541 doesn't match the expected checksum (perhaps due to the basis file changing
3542 during the transfer), the receiver will no longer retain the resulting file
3543 unless the `--partial` option was specified. (Note: for the read-error
3544 detection to work, neither side can be older than 2.6.3 -- older receivers
3545 will always retain the file, and older senders don't tell the receiver that
3546 the file had a read error.)
3548 - If a file gets resent in a single transfer and the `--backup` option is
3549 enabled, rsync no longer performs a duplicate backup (it used to overwrite
3550 the original file in the backup area).
3552 - Files specified in the daemon's `exclude` or `exclude from` config items are
3553 now excluded from being uploaded (assuming that the module allows uploading
3554 at all) in addition to the old download exclusion.
3556 - Got rid of a potential hang in the receiver when near the end of a phase.
3558 - When using `--backup` without a `--backup-dir`, rsync no longer preserves
3559 the modify time on directories. This avoids confusing NFS.
3561 - When `--copy-links` (`-L`) is specified, we now output a separate error for
3562 a symlink that has no referent instead of claiming that a file `vanished`.
3564 - The `--copy-links` (`-L`) option no longer has the side-effect of telling
3565 the receiving side to follow symlinks. See the `--keep-dirlinks` option
3566 (mentioned below) for a way to specify that behavior.
3568 - Error messages from the daemon server's option-parsing (such as refused
3569 options) are now successfully transferred back to the client (the server
3570 used to fail to send the message because the socket wasn't in the right
3571 state for the message to get through).
3573 - Most transfer errors that occur during a daemon transfer are now returned to
3574 the user in addition to being logged (some messages are intended to be
3575 daemon-only and are not affected by this).
3577 - Fixed a bug in the daemon authentication code when using one of the
3578 batch-processing options.
3580 - We try to work around some buggy IPv6 implementations that fail to implement
3581 `IPV6_V6ONLY`. This should fix the `address in use` error that some daemons
3582 get when running on an OS with a buggy IPv6 implementation. Also, if the new
3583 code gets this error, we might suggest that the user specify `--ipv4` or
3584 `--ipv6` (if we think it will help).
3586 - When the remote rsync dies, make a better effort to recover any error
3587 messages it may have sent before dying (the local rsync used to just die
3588 with a socket-write error).
3590 - When using `--delete` and a `--backup-dir` that contains files that are
3591 hard-linked to their destination equivalents, rsync now makes sure that
3592 removed files really get removed (avoids a really weird rename() behavior).
3594 - Avoid a bogus run-time complaint about a lack of 64-bit integers when the
3595 int64 type is defined as an `off_t` and it actually has 64-bits.
3597 - Added a configure check for open64() without mkstemp64() so that we can
3598 avoid using mkstemp() when such a combination is encountered. This bypasses
3599 a problem writing out large temp files on OSes such as AIX and HP-UX.
3601 - Fixed an age-old crash problem with `--read-batch` on a local copy (rsync
3602 was improperly assuming `--whole-file` for the local copy).
3604 - When `--dry-run` (`-n`) is used and the destination directory does not
3605 exist, rsync now produces a correct report of files that would be sent
3606 instead of dying with a chdir() error.
3608 - Fixed a bug that could cause a slow-to-connect rsync daemon to die with an
3609 error instead of waiting for the connection to finish.
3611 - Fixed an ssh interaction that could cause output to be lost when the user
3612 chose to combine the output of rsync's stdout and stderr (e.g. using the
3615 - Fixed an option-parsing bug when `--files-from` got passed to a daemon.
3619 - Added the `--partial-dir=DIR` option that lets you specify where to
3620 (temporarily) put a partially transferred file (instead of overwriting the
3621 destination file). E.g. `--partial-dir=.rsync-partial` Also added support
3622 for the `RSYNC_PARTIAL_DIR` environment variable that, when found,
3623 transforms a regular `--partial` option (such as the convenient `-P` option)
3624 into one that also specifies a directory.
3626 - Added `--keep-dirlinks` (`-K`), which allows you to symlink a directory onto
3627 another partition on the receiving side and have rsync treat it as matching
3628 a normal directory from the sender.
3630 - Added the `--inplace` option that tells rsync to write each destination file
3631 without using a temporary file. The matching of existing data in the
3632 destination file can be severely limited by this, but there are also cases
3633 where this is more efficient (such as appending data). Use only when needed
3634 (see the manpage for more details).
3636 - Added the `write only` option for the daemon's config file.
3638 - Added long-option names for `-4` and `-6` (namely `--ipv4` and `--ipv6`) and
3639 documented all these options in the manpage.
3641 - Improved the handling of the `--bwlimit` option so that it's less bursty,
3642 more accurate, and works properly over a larger range of values.
3644 - The rsync daemon-over-ssh code now looks for `SSH_CONNECTION` and
3645 `SSH2_CLIENT` in addition to `SSH_CLIENT` to figure out the IP address.
3647 - Added the `--checksum-seed=N` option for advanced users.
3649 - Batch writing/reading has a brand-new implementation that is simpler, fixes
3650 a few weird problems with the old code (such as no longer sprinkling the
3651 batch files into different dirs or even onto different systems), and is much
3652 less intrusive into the code (making it easier to maintain for the future).
3653 The new code generates just one data file instead of three, which makes it
3654 possible to read the batch on stdin via a remote shell. Also, the old
3655 requirement of forcing the same fixed checksum-seed for all batch processing
3658 - If an rsync daemon has a module set with `list = no` (which hides its
3659 presence in the list of available modules), a user that fails to
3660 authenticate gets the same `unknown module` error that they would get if the
3661 module were actually unknown (while still logging the real error to the
3662 daemon's log file). This prevents fishing for module names.
3664 - The daemon's `refuse options` config item now allows you to match option
3665 names using wildcards and/or the single-letter option names.
3667 - Each transferred file now gets its permissions and modified-time updated
3668 before the temp-file gets moved into place. Previously, the finished file
3669 would have a very brief window where its permissions disallowed all group
3672 - Added the ability to parse a literal IPv6 address in an `rsync:` URL (e.g.
3673 rsync://[2001:638:500:101::21]:873/module/dir).
3675 - The daemon's wildcard expanding code can now handle more than 1000 filenames
3676 (it's now limited by memory instead of having a hard-wired limit).
3680 - Some cleanup in the exclude code has saved some per-exclude memory and made
3681 the code easier to maintain.
3683 - Improved the argv-overflow checking for a remote command that has a lot of
3686 - Use rsyserr() in the various places that were still calling rprintf() with
3687 strerror() as an arg.
3689 - If an rsync daemon is listening on multiple sockets (to handle both IPv4 and
3690 IPv6 to a single port), we now close all the unneeded file handles after we
3691 accept a connection (we used to close just one of them).
3693 - Optimized the handling of larger block sizes (rsync used to slow to a crawl
3694 if the block size got too large).
3696 - Optimized away a loop in `hash_search()`.
3698 - Some improvements to the `sanitize_path()` and `clean_fname()` functions
3699 makes them more efficient and produce better results (while still being
3700 compatible with the file-name cleaning that gets done on both sides when
3701 sending the file-list).
3703 - Got rid of `alloc_sanitize_path()` after adding a destination-buffer arg to
3704 `sanitize_path()` made it possible to put all the former's functionality
3707 - The file-list that is output when at least 4 verbose options are specified
3708 reports the uid value on the sender even when rsync is not running as root
3709 (since we might be sending to a root receiver).
3713 - Added a `gen` target to rebuild most of the generated files, including
3714 configure, config.h.in, the manpages, and proto.h.
3716 - If `make proto` doesn't find some changes in the prototypes, the proto.h
3717 file is left untouched (its time-stamp used to always be updated).
3719 - The variable `$STRIP` (that is optionally set by the install-strip target's
3720 rule) was changed to `$INSTALL_STRIP` because some systems have `$STRIP`
3721 already set in the environment.
3723 - Fixed a build problem when `SUPPORT_HARD_LINKS` isn't defined.
3725 - When cross-compiling, the gettimeofday() function is now assumed to be a
3726 modern version that takes two-args (since we can't test it).
3728 ### DEVELOPER RELATED:
3730 - The scripts in the testsuite dir were cleaned up a bit and a few new tests
3733 - Some new diffs were added to the patches dir, and some accepted ones were
3736 ------------------------------------------------------------------------------
3738 # NEWS for rsync 2.6.2 (30 Apr 2004)
3740 ## Changes in this version:
3744 - Fixed a major bug in the sorting of the filenames when `--relative` is used
3745 for some sources (just sources such as `/` and `/*` were affected). This fix
3746 ensures that we ask for the right file-list item when requesting changes
3749 - Rsync now checks the return value of the close() function to better report
3750 disk-full problems on an NFS file system.
3752 - Restored the old daemon-server behavior of logging error messages rather
3753 than returning them to the user. (A better long-term fix will be sought in
3756 - An obscure uninitialized-variable bug was fixed in the uid/gid code. (This
3757 bug probably had no ill effects.)
3761 - Got rid of the configure check for sys/sysctl.h (it wasn't used and was
3762 causing a problem on some systems). Also improved the
3763 broken-largefile-locking test to try to avoid failure due to an NFS
3766 - Fixed a compile problem on systems that don't define `AI_NUMERICHOST`.
3768 - Fixed a compile problem in the popt source for compilers that don't support
3771 ### DEVELOPER RELATED:
3773 - Improved the testsuite's `merge` test to work on OSF1.
3775 - Two new diffs were added to the patches dir.
3777 ------------------------------------------------------------------------------
3779 # NEWS for rsync 2.6.1 (26 Apr 2004)
3781 ## Changes in this version:
3783 ### PROTOCOL NUMBER:
3785 - The protocol number was changed to 28.
3789 - Paths sent to an rsync daemon are more thoroughly sanitized when chroot is
3790 not used. If you're running a non-read-only rsync daemon with chroot
3791 disabled, **please upgrade**, ESPECIALLY if the user privs you run rsync
3792 under is anything above `nobody`.
3796 - Lower memory use, more optimal transfer of data over the socket, and lower
3797 CPU usage (see the INTERNAL section for details).
3799 - The `RSYNC_PROXY` environment variable can now contain a `USER:PASS@` prefix
3800 before the `HOST:PORT` information. (Bardur Arantsson)
3802 - The `--progress` output now mentions how far along in the transfer we are,
3803 including both a count of files transferred and a percentage of the total
3804 file-count that we've processed. It also shows better
3805 current-rate-of-transfer and remaining-transfer-time values.
3807 - Documentation changes now attempt to describe some often misunderstood
3808 features more clearly.
3812 - When `-x` (`--one-file-system`) is combined with `-L` (`--copy-links`) or
3813 `--copy-unsafe-links,` no symlinked files are skipped, even if the referent
3814 file is on a different filesystem.
3816 - The `--link-dest` code now works properly for a non-root user when (1) the
3817 UIDs of the source and destination differ and `-o` was specified, or (2)
3818 when the group of the source can't be used on the destination and `-g` was
3821 - Fixed a bug in the handling of `-H` (hard-links) that might cause the
3822 expanded PATH/NAME value of the current item to get overwritten (due to an
3823 expanded-name caching bug).
3825 - We now reset the `new data has been sent` flag at the start of each file we
3826 send. This makes sure that an interrupted transfer with the `--partial`
3827 option set doesn't keep a shorter temp file than the current basis file when
3828 no new data has been transferred over the wire for that file.
3830 - Fixed a byte-order problem in `--batch-mode` on big-endian machines. (Jay
3833 - When using `--cvs-exclude`, the exclude items we get from a per-directory's
3834 .cvsignore file once again only affect that one directory (not all following
3835 directories too). The items are also now properly word-split and parsed
3836 without any +/- prefix parsing.
3838 - When specifying the USER@HOST: prefix for a file, the USER part can now
3839 contain an '@', if needed (i.e. the last '@' is used to find the HOST, not
3842 - Fixed some bugs in the handling of group IDs for non-root users: (1) It
3843 properly handles a group that the sender didn't have a name for (it would
3844 previously skip changing the group on any files in that group). (2) If
3845 `--numeric-ids` is used, rsync no longer attempts to set groups that the
3846 user doesn't have the permission to set.
3848 - Fixed the `refuse options` setting in the rsyncd.conf file.
3850 - Improved the `-x` (`--one-file-system`) flag's handling of any mount-point
3851 directories we encounter. It is both more optimal (in that it no longer does
3852 a useless scan of the contents of the mount-point dirs) and also fixes a
3853 bug where a remapped mount of the original filesystem could get discovered
3854 in a subdir we should be ignoring.
3856 - Rsync no longer discards a double-slash at the start of a filename when
3857 trying to open the file. It also no longer constructs names that start with
3858 a double slash (unless the user supplied them).
3860 - Path-specifying options to a daemon should now work the same with or without
3861 chroot turned on. Previously, such a option (such as `--link-dest`) would
3862 get its absolute path munged into a relative one if chroot was not on,
3863 making that setting fairly useless. Rsync now transforms the path into one
3864 that is based on the module's base dir when chroot is not enabled.
3866 - Fixed a compatibility problem interacting with older rsync versions that
3867 might send us an empty `--suffix` value without telling us that
3868 `--backup-dir` was specified.
3870 - The `hosts allow` option for a daemon-over-remote-shell process now has
3871 improved support for IPv6 addresses and a fix for systems that have a length
3872 field in their socket structs.
3874 - Fixed the ability to request an empty backup `--suffix` when sending files
3877 - Fixed an option-parsing bug when `--files-from` was sent to a server sender.
3881 - Most of the I/O is now buffered, which results in a pretty large speedup
3882 when running under MS Windows. (Craig Barratt)
3884 - Optimizations to the name-handling/comparing code have made some significant
3885 reductions in user-CPU time for large file sets.
3887 - Some cleanup of the variable types make the code more consistent.
3889 - Reduced memory requirements of hard link preservation. (J.W. Schultz)
3891 - Implemented a new algorithm for hard-link handling that speeds up the code
3892 significantly. (J.W. Schultz and Wayne Davison)
3894 - The `--hard-link` option now uses the first existing file in the group of
3895 linked files as the basis for the transfer. This prevents the sub-optimal
3896 transfer of a file's data when a new hardlink is added on the sending side
3897 and it sorts alphabetically earlier in the list than the files that are
3898 already present on the receiving side.
3900 - Dropped support for protocol versions less than 20 (2.3.0 released 15 Mar
3901 1999) and activated warnings for protocols less than 25 (2.5.0 released 23
3902 Aug 2001). (Wayne Davison and J.W. Schultz, severally)
3904 - More optimal data transmission for `--hard-links` (protocol 28).
3906 - More optimal data transmission for `--checksum` (protocol 28).
3908 - Less memory is used when `--checksum` is specified.
3910 - Less memory is used in the file list (a per-file savings).
3912 - The generator is now better about not modifying the file list during the
3913 transfer in order to avoid a copy-on-write memory bifurcation (on systems
3914 where fork() uses shared memory). Previously, rsync's shared memory would
3915 slowly become unshared, resulting in real memory usage nearly doubling on
3916 the receiving side by the end of the transfer. Now, as long as permissions
3917 are being preserved, the shared memory should remain that way for the entire
3920 - Changed hardlink info and `file_struct` + strings to use allocation pools.
3921 This reduces memory use for large file-sets and permits freeing memory to
3922 the OS. (J.W. Schultz)
3924 - The 2 pipes used between the receiver and generator processes (which are
3925 forked on the same machine) were reduced to 1 pipe and the protocol improved
3926 so that (1) it is now impossible to have the `redo` pipe fill up and hang
3927 rsync, and (2) trailing messages from the receiver don't get lost on their
3928 way through the generator over to the sender (which mainly affected
3929 hard-link messages and verbose `--stats` output).
3931 - Improved the internal uid/gid code to be more portable and a little more
3934 - The device numbers sent when using `--devices` are now sent as separate
3935 major/minor values with 32-bit accuracy (protocol 28). Previously, the
3936 copied devices were sent as a single 32-bit number. This will make
3937 inter-operation of 64-bit binaries more compatible with their 32-bit
3938 brethren (with both ends of the connection are using protocol 28). Note that
3939 optimizations in the binary protocol for sending the device numbers often
3940 results in fewer bytes being used than before, even though more precision is
3943 - Some cleanup of the exclude/include structures and its code made things
3944 clearer (internally), simpler, and more efficient.
3946 - The reading & writing of the file-list in batch-mode is now handled by the
3947 same code that sends & receives the list over the wire. This makes it much
3948 easier to maintain. (Note that the batch code is still considered to be
3953 - The configure script now accepts `--with-rsyncd-conf=PATH` to override the
3954 default value of the /etc/rsyncd.conf file.
3956 - Fixed configure bug when running `./configure --disable-ipv6`.
3958 - Fixed compilation problem on Tru64 Unix (having to do with `sockaddr.sa_len`
3959 and `sockaddr.sin_len`).
3961 ### DEVELOPER RELATED:
3963 - Fixed `make test` bug when build dir is not the source dir.
3965 - Added a couple extra diffs in the `patches` dir, removed the ones that got
3966 applied, and rebuilt the rest.
3968 ------------------------------------------------------------------------------
3970 # NEWS for rsync 2.6.0 (1 Jan 2004)
3972 ## Changes in this version:
3974 ### PROTOCOL NUMBER:
3976 - The protocol number was changed to 27. The maximum accepted protocol number
3977 was increased from 30 to 40.
3981 - `ssh` is now the default remote shell for rsync. If you want to change this,
3982 configure like this: `./configure --with-rsh=rsh`.
3984 - Added `--files-from`, `--no-relative`, `--no-implied-dirs`, and `--from0`.
3985 Note that `--from0` affects the line-ending character for all the files read
3986 by the `--*-from` options. (Wayne Davison)
3988 - Length of csum2 is now per-file starting with protocol version
3991 - Per-file dynamic block size is now sqrt(file length). The per-file checksum
3992 size is determined according to an algorithm provided by Donovan Baarda
3993 which reduces the probability of rsync algorithm corrupting data and falling
3994 back using the whole md4 checksums. (J.W. Schultz, Donovan Baarda)
3996 - The `--stats` option no longer includes the (debug) malloc summary unless
3997 the verbose option was specified at least twice.
3999 - Added a new error/warning code for when files vanish from the sending side.
4000 Made vanished source files not interfere with the file-deletion pass when
4001 `--delete-after` was specified.
4003 - Various trailing-info sections are now preceded by a newline.
4007 - Fixed several exclude/include matching bugs when using wild-cards. This has
4008 a several user-visible effects, all of which make the matching more
4009 consistent and intuitive. This should hopefully not cause anyone problems
4010 since it makes the matching work more like what people are expecting. (Wayne
4013 - A pattern with a `**` no longer causes a `*` to match slashes. For example,
4014 with `/*/foo/**`, `foo` must be 2 levels deep. [If your string has BOTH `*`
4015 and `**` wildcards, changing the `*` wildcards to `**` will provide the old
4016 behavior in all versions.]
4018 - `**/foo` now matches at the base of the transfer (like /foo does). [Use
4019 `/**/foo` to get the old behavior in all versions.]
4021 - A non-anchored wildcard term floats to match beyond the base of the
4022 transfer. E.g. `CVS/R*` matches at the end of the path, just like the
4023 non-wildcard term `CVS/Root` does. [Use `/CVS/R*` to get the old behavior in
4026 - Including a `**` in the match term causes it to be matched against the
4027 entire path, not just the name portion, even if there aren't any interior
4028 slashes in the term. E.g. `foo**bar` would exclude `/path/foo-bar` (just
4029 like before) as well as `/foo-path/baz-bar` (unlike before). [Use `foo*bar`
4030 to get the old behavior in all versions.]
4032 - The exclude list specified in the daemon's config file is now properly
4033 applied to the pulled items no matter how deep the user's file-args are in
4034 the source tree. (Wayne Davison)
4036 - For protocol version >= 27, `mdfour_tail()` is called when the block size
4037 (including `checksum_seed`) is a multiple of 64. Previously it was not
4038 called, giving the wrong MD4 checksum. (Craig Barratt)
4040 - For protocol version >= 27, a 64 bit bit counter is used in mdfour.c as
4041 required by the RFC. Previously only a 32 bit bit counter was used, causing
4042 incorrect MD4 file checksums for file sizes >= 512MB - 4. (Craig Barratt)
4044 - Fixed a crash bug when interacting with older rsync versions and multiple
4045 files of the same name are destined for the same dir. (Wayne Davison)
4047 - Keep tmp names from overflowing MAXPATHLEN.
4049 - Make `--link-dest` honor the absence of `-p`, `-o`, and `-g`.
4051 - Made rsync treat a trailing slash in the destination in a more consistent
4054 - Fixed file I/O error detection. (John Van Essen)
4056 - Fixed bogus `malformed address {hostname}` message in rsyncd log when
4057 checking IP address against hostnames from `hosts allow` and `hosts deny`
4058 parameters in config file.
4060 - Print heap statistics when verbose >= 2 instead of when >= 1.
4062 - Fixed a compression (`-z`) bug when syncing a mostly-matching file that
4063 contains already-compressed data. (Yasuoka Masahiko and Wayne Davison)
4065 - Fixed a bug in the `--backup` code that could cause deleted files to not get
4068 - When the backup code makes new directories, create them with mode 0700
4069 instead of 0755 (since the directory permissions in the backup tree are not
4070 yet copied from the main tree).
4072 - Call setgroups() in a more portable manner.
4074 - Improved file-related error messages to better indicate exactly what
4075 pathname failed. (Wayne Davison)
4077 - Fixed some bugs in the handling of `--delete` and `--exclude` when using the
4078 `--relative` (`-R`) option. (Wayne Davison)
4080 - Fixed bug that prevented regular files from replacing special files and
4081 caused a directory in `--link-dest` or `--compare-dest` to block the
4082 creation of a file with the same path. A directory still cannot be replaced
4083 by a regular file unless `--delete` specified. (J.W. Schultz)
4085 - Detect and report when open or opendir succeed but read and readdir fail
4086 caused by network filesystem issues and truncated files. (David Norwood,
4087 Michael Brown, J.W. Schultz)
4089 - Added a fix that should give ssh time to restore the tty settings if the
4090 user presses Ctrl-C at an ssh password prompt.
4094 - Eliminated vestigial support for old versions that we stopped supporting.
4097 - Simplified some of the option-parsing code. (Wayne Davison)
4099 - Some cleanup made to the exclude code, as well as some new defines added to
4100 enhance readability. (Wayne Davison)
4102 - Changed the protocol-version code so that it can interact at a lower
4103 protocol level than the maximum supported by both sides. Added an
4104 undocumented option, `--protocol=N`, to force the value we advertise to the
4105 other side (primarily for testing purposes). (Wayne Davison)

4118 ------------------------------------------------------------------------------
4120 # NEWS for rsync 2.5.6, aka "the dwd-between-jobs release" (26 Jan 2003)
4122 ## Changes in this version:
4126 - The `--delete-after` option now implies `--delete`. (Wayne Davison)
4128 - The `--suffix` option can now be used with `--backup-dir`. (Michael
4131 - Combining `::` syntax with the `--rsh`/`-e` option now uses the specified
4132 remote-shell as a transport to talk to a (newly-spawned) server-daemon. This
4133 allows someone to use daemon features, such as modules, over a secure
4134 protocol, such as ssh. (JD Paul)
4136 - The rsync:// syntax for daemon connections is now accepted in the
4139 - If the file name given to `--include-from` or `--exclude-from` is `-`, rsync
4140 will read from standard input. (J.W. Schultz)
4142 - New option `--link-dest` which is like `--compare-dest` except that
4143 unchanged files are hard-linked in to the destination directory. (J.W.
4146 - Don't report an error if an excluded file disappears during an rsync run.
4147 (Eugene Chupriyanov and Bo Kersey)
4149 - Added .svn to `--cvs-exclude` list to support subversion. (Jon Middleton)
4151 - Properly support IPv6 addresses in the rsyncd.conf `hosts allow` and `hosts
4152 deny` fields. (Hideaki Yoshifuji)
4154 - Changed exclude file handling to permit DOS or MAC style line terminations.
4157 - Ignore errors from chmod when `-p`/`-a`/`--preserve-perms` is not set.
4162 - Fix `forward name lookup failed` errors on AIX 4.3.3. (John L. Allen, Martin
4165 - Generate each file's rolling-checksum data as we send it, not in a separate
4166 (memory-eating) pass before hand. This prevents timeout errors on really
4167 large files. (Stefan Nehlsen)
4169 - Fix compilation on Tru64. (Albert Chin, Zoong Pham)
4171 - Better handling of some client-server errors. (Martin Pool)
4173 - Fixed a crash that would occur when sending a list of files that contains a
4174 duplicate name (if it sorts to the end of the file list) and using
4175 `--delete`. (Wayne Davison)
4177 - Fixed the file-name duplicate-removal code when dealing with multiple dups
4178 in a row. (Wayne Davison)
4180 - Fixed a bug that caused rsync to lose the exit status of its child processes
4181 and sometimes return an exit code of 0 instead of showing an error. (David
4182 R. Staples, Dave Dykstra)
4184 - Fixed bug in `--copy-unsafe-links` that caused it to be completely broken.
4187 - Prevent infinite recursion in cleanup code under certain circumstances.
4188 (Sviatoslav Sviridov and Marc Espie)
4190 - Fixed a bug that prevented rsync from creating intervening directories when
4191 `--relative-paths`/`-R` is set. (Craig Barratt)
4193 - Prevent `Connection reset by peer` messages from Cygwin. (Randy O'Meara)
4197 - Many code cleanups and improved internal documentation. (Martin Pool, Nelson
4200 - Portability fixes. (Dave Dykstra and Wayne Davison)
4202 - More test cases. (Martin Pool)
4204 - Some test-case fixes. (Brian Poole, Wayne Davison)
4206 - Updated included popt to the latest vendor drop, version 1.6.4. (Jos
4209 - Updated config.guess and config.sub to latest versions; this means rsync
4210 should build on more platforms. (Paul Green)
4212 ------------------------------------------------------------------------------
4214 # NEWS for rsync 2.5.5, aka Snowy River (2 Apr 2002)
4216 ## Changes in this version:
4220 - With `--progress`, when a transfer is complete show the time taken;
4221 otherwise show expected time to complete. (Cameron Simpson)
4223 - Make `make install-strip` works properly, and `make install` accepts a
4224 DESTDIR variable for help in building binary packages. (Peter
4225 Breitenlohner, Greg Louis)
4227 - If configured with `--enable-maintainer-mode`, then on receipt of a fatal
4228 signal rsync will try to open an xterm running gdb, similarly to Samba's
4229 `panic action` or GNOME's bug-buddy. (Martin Pool)
4233 - Fix situation where failure to fork (e.g. because out of process slots)
4234 would cause rsync to kill all processes owned by the current user. Yes,
4235 really! (Paul Haas, Martin Pool)
4237 - Fix test suite on Solaris. (Jos Backus, Martin Pool)
4239 - Fix minor memory leak in socket code. (Dave Dykstra, Martin Pool.)
4241 - Fix `--whole-file` problem that caused it to be the default even for remote
4242 connections. (Martin Pool, Frank Schulz)
4244 - Work around bug in Mac OS X mkdir(2), which cannot handle trailing slashes.
4245 <http://www.opensource.apple.com/bugs/X/BSD%20Kernel/2734739.html> (Martin
4248 - Improved network error handling. (Greg A. Woods)
4250 ------------------------------------------------------------------------------
4252 # NEWS for rsync 2.5.4, aka "Imitation lizard skin" (13 Mar 2002)
4254 ## Changes in this version:
4258 - Additional fix for zlib double-free bug. (Martin Pool, Andrew Tridgell) (CVE
4263 - Merge in changes from zlib 1.1.3 to zlib 1.1.4. (Jos Backus) (Note that
4264 rsync still uses a custom version of zlib; you can not just link against a
4265 system library. See zlib/README.rsync)
4267 - Additional test cases for `--compress`. (Martin Pool)
4269 ------------------------------------------------------------------------------
4271 # NEWS for rsync 2.5.3, aka "Happy 26" (11 Mar 2002)
4273 ## Changes in this version:
4277 - Make sure that supplementary groups are removed from a server
4278 process after changing uid and gid. (Ethan Benson) (Debian bug
4279 #132272, CVE CAN-2002-0080)
4283 - Fix zlib double-free bug. (Owen Taylor, Mark J Cox) (CVE CAN-2002-0059)
4285 - Fixed problem that in many cases caused the error message unexpected read
4286 size of 0 in `map_ptr` and resulted in the wrong data being copied.
4288 - Fixed compilation errors on some systems caused by the use of `unsigned
4291 - Fixed problem on systems such as Sunos4 that do not support realloc on a
4292 NULL pointer; error was 'out of memory in "flist_expand"'.
4294 - Fix for rsync server processes hanging around after the client unexpectedly
4295 disconnects. (Colin Walters) (Debian bug #128632)
4297 - Cope with BSD systems on which mkdir() will not accept a trailing slash.
4301 - Merge in changes from zlib 1.1.2 to zlib 1.1.3. (Note that rsync still uses
4302 a custom version of zlib; you can not just link against a system library.
4303 See zlib/README.rsync)
4305 - Command to initiate connections is only shown with `-vv`, rather than `-v`
4306 as in 2.5.2. Output from plain `-v` is more similar to what was historically
4307 used so as not to break scripts that try to parse the output.
4309 - Added `--no-whole-file` and `--no-blocking-io` options (Dave Dykstra)
4311 - Made the `--write-batch` and `--read-batch` options actually work and added
4312 documentation in the manpage (Jos Backus)
4314 - If the daemon is unable to fork a child to accept a connection, print an
4315 error message. (Colin Walters)
4317 ------------------------------------------------------------------------------
4319 # NEWS for rsync 2.5.2 (26 Jan 2002)
4321 ## Changes in this version:
4325 - Signedness security patch from Sebastian Krahmer <krahmer@suse.de> -- in
4326 some cases we were not sufficiently careful about reading integers from the
4329 ### PROTOCOL NUMBER:
4331 - The protocol number was changed to 26.
4335 - Fix possible string mangling in log files.
4337 - Fix for setting local address of outgoing sockets.
4339 - Better handling of hardlinks and devices on platforms with 64-bit `dev_t` or
4342 - Name resolution on machines supporting IPv6 is improved.
4344 - Fix for device nodes. (dann frazier) (Debian #129135)
4348 - With `-v`, rsync now shows the command used to initiate an ssh/rsh
4351 - `--statistics` now shows memory heap usage on platforms that support
4354 - "The Ted T'so school of program optimization": make progress visible and
4355 people will think it's faster. (With `--progress`, rsync will show you how
4356 many files it has seen as it builds the `file_list`, giving some indication
4357 that it has not hung.)
4359 - Improvements to batch mode support. This is still experimental but testing
4360 would be welcome. (Jos Backus)
4362 - New `--ignore-existing` option, patch previously distributed with Vipul's
4363 Razor. (Debian #124286)
4365 ------------------------------------------------------------------------------
4367 # NEWS for rsync 2.5.1 (3 Jan 2002)
4369 ## Changes in this version:
4373 - Fix for segfault in `--daemon` mode configuration parser. (Paul Mackerras)
4375 - Correct `string<->address` parsing for both IPv4 and 6. (YOSHIFUJI Hideaki,
4376 SUMIKAWA Munechika and Jun-ichiro `itojun` Hagino)
4378 - Various fixes for IPv6 support. (Dave Dykstra)
4380 - rsync.1 typo fix. (Matt Kraai)
4382 - Test suite typo fixes. (Tom Schmidt)
4384 - rsync.1 grammar and clarity improvements. (Edward Welbourne)
4386 - Correction to ./configure tests for `inet_ntop`. (Jeff Garzik)
4390 - `--progress` and `-P` now show estimated data transfer rate (in a multiple
4391 of bytes/s) and estimated time to completion. (Rik Faith)
4393 - `--no-detach` option, required to run as a W32 service and also useful when
4394 running on Unix under daemontools, AIX's SRC, or a debugger. (Max Bowsher,
4397 - Clearer error messages for some conditions.
4399 ------------------------------------------------------------------------------
4401 # NEWS for rsync 2.5.0 (30 Nov 2001)
4403 ## Changes in this version:
4405 ### PROTOCOL NUMBER:
4407 - The protocol number was changed to 25.
4411 - Martin Pool <mbp@samba.org> is now a co-maintainer.
4415 - Support for LSB-compliant packaging <http://www.linuxbase.org/>
4417 - Shell wildcards are allowed in `auth users` lines.
4419 - Merged UNC rsync+ patch to support creation of standalone patch sets. By
4420 Bert J. Dempsey and Debra Weiss, updated by Jos Backus.
4421 <http://www.ils.unc.edu/i2dsi/unc_rsync+.html>
4423 - IPv6 support based on a patch from KAME.net, on systems including modern
4424 versions of Linux, Solaris, and HP-UX. Also includes IPv6 compatibility
4425 functions for old OSs by the Internet Software Consortium, Paul Vixie, the
4426 OpenSSH portability project, and OpenBSD.
4430 - Include/exclude cluestick: with `-vv`, print out whether files are included
4431 or excluded and why.
4433 - Many error messages have more friendly explanations and more details.
4435 - Manual page improvements plus scanty protocol documentation.
4437 - When running as `--daemon` in the background and using a `log file`
4438 rsyncd.conf directive, close the log file every time it is open when going
4439 to sleep on the socket. This allows the log file to get cleaned out by
4442 - Change to using libpopt rather than getopt for processing options. This
4443 makes the code cleaner and the behaviour more consistent across platforms.
4444 popt is included and built if not installed on the platform.
4446 - More details in `--version`, including note about whether 64-bit files,
4447 symlinks and hardlinks are supported.
4449 - MD4 code may use less CPU cycles.
4451 - Use mkstemp on systems where it is secure. If we use mktemp, explain that we
4452 do it in a secure way.
4454 - `--whole-file` is the default when source and target are on the local
4459 - Fix for various bugs causing rsync to hang.
4461 - Attempt to fix Large File Summit support on AIX.
4463 - Attempt to fix error handling lockup bug.
4465 - Give a non-0 exit code if **any** of the files we have been asked to
4466 transfer fail to transfer.
4468 - For log messages containing ridiculously long strings that might overflow a
4469 buffer rsync no longer aborts, but rather prints an ellipsis at the end of
4470 the string. (Patch from Ed Santiago.)
4474 - Improved support for UNICOS (tested on Cray T3E and Cray SV1)
4476 - autoconf2.52 (or later) is now required to rebuild the autoconf scripts. It
4477 is not required to simply build rsync.
4479 - Platforms thought to work in this release:
