1 # NEWS for rsync 3.2.4 (UNRELEASED)
3 ## Changes in this version:
7 - A new form of arg protection was added that works similarly to the older
8 [`--protect-args`](rsync.1#opt) (`-s`) option but in a way that avoids
9 breaking things like rrsync (the restricted rsync script): rsync now uses
10 backslash escaping for sending "shell-active" characters to the remote
11 shell. This includes spaces, so fetching a remote file via a simple quoted
12 filename value now works by default without any extra quoting:
15 rsync -aiv host:'a simple file.pdf' .
18 Wildcards are not escaped in filename args, but they are escaped in options
19 like the [`--suffix`](rsync.1#opt) and [`--usermap`](rsync.1#opt) values.
20 If your rsync script depends on the old arg-splitting behavior, either run
21 it with the [`--old-args`](rsync.1#opt) option or `export RSYNC_OLD_ARGS=1`
22 in the script's environment. See also the [ADVANCED USAGE](rsync.1#)
23 section of rsync's manpage for how to use a more modern arg style.
25 - A long-standing bug was preventing rsync from figuring out the current
26 locale's decimal point character, which made rsync always output numbers
27 using the "C" locale. Since this is now fixed in 3.2.4, a script that
28 parses rsync's decimal numbers (e.g. from the verbose footer) may want to
29 setup the environment in a way that the output continues to be in the C
30 locale. For instance, one of the following should work fine:
36 or if iconv translations are needed:
39 if [ "${LC_ALL:-}" ]; then
41 export LC_CTYPE="$LC_ALL"
44 export LC_NUMERIC=C.UTF-8
49 - A fix for CVE-2018-25032 in the bundled zlib (memory corruption issue).
53 - Fixed a bug with [`--inplace`](rsync.1#opt) + [`--sparse`](rsync.1#opt) (and
54 a lack of [`--whole-file`](rsync.1#opt)) where the destination file could
55 get reconstructed with bogus data. Since the bug can also be avoided by
56 using (the seemingly redundant) [`--no-W`](rsync.1#opt) on the receiving
57 side, the latest rsync will now send `--no-W` to a remote receiver when this
58 option combination occurs. If your client rsync is not new enough to do
59 this for you (or if you're just paranoid), you can manually specify `--no-W
60 -M--no-W` (when not using [`--whole-file`](rsync.1#opt)) to make sure the
63 - Fixed a bug with [`--mkpath`](rsync.1#opt) if a single-file copy specifies
64 an existing destination dir with a non-existing destination filename.
66 - Fixed `--update -vv` to output "is uptodate" instead of "is newer" messages
67 for files that are being skipped due to an identical modify time. (This was
68 a new output quirk in 3.2.3.)
70 - When doing an append transfer, the sending side's file must not get shorter
71 or it is skipped. Fixes a crash that could occur when the size changes to 0
72 in the middle of the send negotiations.
74 - When dealing with special files (see [`--specials`](rsync.1#opt)) in an
75 alt-dest hierarchy, rsync now checks the non-permission mode bits to ensure
76 that the 2 special files are really the same before hard-linking them
79 - Fixed a bug where [`--delay-updates`](rsync.1#opt) with stale partial data
80 could cause a file to fail to update.
82 - Fixed a few places that would output an INFO message with
83 [`--info=NAME`](rsync.1#opt) that should only have been output given
84 [`--verbose`](rsync.1#opt) or [`--itemize-changes`](rsync.1#opt).
86 - Avoid a weird failure if you run a local copy with a (useless)
87 [`--rsh`](rsync.1#opt) option that contains a `V` in the command.
89 - Fixed a long-standing compression bug where the compression level of the
90 first file transferred affected the level for all future files. Also, the
91 per-file compression skipping has apparently never worked, so it is now
92 documented as being ineffective.
94 - Fixed a truncate error when a `--write-devices` copy wrote a file onto a
95 device that was shorter than the device.
97 - Made `--write-devices` support both `--checksum` and `--no-whole-file` when
100 - Improved how the [`--stop-at`](rsync.1#opt), [`--stop-after`](rsync.1#opt),
101 and (the deprecated) [`--time-limit`](rsync.1#opt) options check to see if
102 the allowed time is over, which should make rsync exit more consistently.
104 - Tweak --progress to display "`??:??:??`" when the time-remaining value is so
105 large as to be meaningless.
107 - Silence some chmod warnings about symlinks when it looks like we have a
108 function to set their permissions but they can't really be set.
110 - Fixed a potential issue in git-set-file-times when handling commits with
111 high-bit characters in the description & when handling a description that
112 might mimick the git raw-commit deliniators. (See the support dir.)
114 - The bundled systemd/rsync.service file now includes `Restart=on-failure`.
118 - Use openssl's `-verify_hostname` option in the rsync-ssl script.
120 - Added extra info to the "FILENAME exists" output of
121 [`--ignore-existing`](rsync.1#opt) when [`--info=skip2`](rsync.1#opt) is
122 used. The skip message becomes "FILENAME exists (INFO)" where the INFO is
123 one of "type change", "sum change" (requires [`--checksum`](rsync.1#opt)),
124 "file change" (based on the quick check), "attr change", or "uptodate".
125 Prior versions only supported `--info=skip1`.
127 - Added the [`--fsync`](rsync.1#opt) option (promoted from the patches repo).
129 - Added the [`--copy-devices`](rsync.1#opt) option. Compared to the
130 historical version from the rsync-patches repo, this version: properly
131 handles `--checksum`; fixes a truncation bug when doing an `--inplace` copy
132 onto a longer file; fixes several bugs in the `--itemize` output; and only
133 the sending side needs the enhanced rsync for the copy to work.
135 - Reduced memory usage for an incremental transfer that has a bunch of small
138 - The rsync daemon can now handle a client address with an implied "%scope"
141 - Added support for [`--atimes`](rsync.1#opt) on macOS and fixed a bug where
142 it wouldn't work without [`--times`](rsync.1#opt).
144 - Rsync can now update the xattrs on a read-only file when your user can
145 temporarily add user-write permission to the file. (It always worked for a
148 - Rsync can now work around an [`--inplace`](rsync.1#opt) update of a file
149 that is being refused due to the Linux fs.protected_regular sysctl setting.
151 - When [`--chown`](rsync.1#opt), [`--usermap`](rsync.1#opt), or
152 [`--groupmap`](rsync.1#opt) is specified, rsync now makes sure that the
153 appropriate [`--owner`](rsync.1#opt) and/or [`--group`](rsync.1#opt) options
156 - Added the [`--info=NONREG`](rsync.1#opt) setting to control if rsync should
157 warn about non-regular files in the transfer. This is enabled by default
158 (keeping the behavior the same as before), so specifying `--info=nonreg0`
159 can be used to turn the warnings off.
161 - An optional asm optimization for the rolling checksum from Shark64. Enable
162 it with `./configure --enable-roll-asm`.
164 - Using `--debug=FILTER` now outputs a caution message if a filter rule
165 has trailing whitespace.
167 - Transformed rrsync into a python script with improvements:
168 - Security has been beefed up.
169 - The known rsync options were updated to include recent additions.
170 - Make rrsync reject [`--copy-links`](rsync.1#opt) (`-L`),
171 [`--copy-dirlinks`](rsync.1#opt) (`-k`), &
172 [`--keep-dirlinks`](rsync.1#opt) (`-K`) by default to make it harder to
173 exploit any out-of-subdir symlinks.
174 - A new rrsync option of [`-munge`](rrsync.1#opt) tells rrsync to always
175 enable rsync's [`--munge-links`](rsync.1#opt) option on the server side.
176 - A new rrsync option of [`-no-lock`](rrsync.1#opt) disables a new
177 single-use locking idiom that is the default when [`-ro`](rrsync.1#opt) is
178 not used (useful with [`-munge`](rrsync.1#opt)).
179 - A new rrsync option of [`-no-del`](rrsync.1#opt) disables all `--remove*`
180 and `--delete*` rsync options on the server side.
181 - The log format has been tweaked slightly to add seconds to the timestamp
182 and to output the command executed as a tuple (making the args clearer).
183 - An rrsync.1 manpage was added (in the support dir with rrsync).
185 - Added options to the lsh script to facilitate rrsync testing. (See the
188 - Transformed the atomic-rsync script into a python script and added the
189 ability to ignore one or more non-zero exit codes. By default, it now
190 ignores code 24, the file-vanished exit code. (See the support dir.)
192 - Transformed the munge-symlinks script into python. (See the support dir.)
194 - Improved the rsync-no-vanished script to not join stdout & stderr together.
195 (See the support dir.)
197 - Work around a glibc bug where lchmod() breaks in a chroot w/o /proc mounted.
199 - Try to support a client that sent a remote rsync a wacko stderr file handle
200 (such as an older File::RsyncP perl library used by BackupPC).
202 - Lots of manpage improvements, including better HTML versions.
204 ### PACKAGING RELATED:
206 - Give configure the `--with-rrsync` option if you want `make install` to
207 install the (now python3) rrsync script and its new manpage.
209 - If the rrsync script is installed, its package should be changed to depend
210 on python3 and the (suggested but not mandatory) python3 braceexpand lib.
212 - When creating a package from a non-release version (w/o a git checkout), the
213 packager can elect to create git-version.h and define RSYNC_GITVER to the
214 string they want `--version` to output. (The file is still auto-generated
215 using the output of `git describe` when building inside a non-shallow git
218 - Renamed configure's `--enable-simd` option to `--enable-roll-simd` and added
219 the option `--enable-roll-asm` to use the new asm version of the code. Both
220 are x86_64/amd64 only.
222 - Renamed configure's `--enable-asm` option to `--enable-md5-asm` to avoid
223 confusion with the asm option for the rolling checksum. It is also honored
224 even when openssl crypto is in use. This allows: normal MD4 & MD5, normal
225 MD4 + asm MD5, openssl MD4 & MD5, or openssl MD4 + asm MD5 depending on the
226 configure options selected.
228 - Made SIMD & asm configure checks default to "no" on non-Linux hosts due to
229 various reports of problems on NetBSD & macOS hosts. These were also
230 tweaked to allow enabling the feature on a host_cpu of amd64 (was only
231 allowed on x86_64 before).
233 - Fixed configure to not fail at the SIMD check when cross-compiling.
235 - Improved the IPv6 determination in configure.
237 - Compile the C files with `-pedantic-errors` (when possible) so that we will
238 get warned if a static initialization overflows in the future (among other
241 - When linking with an external zlib, rsync renames its `read_buf()` function
242 to `read_buf_()` to avoid a symbol clash on an unpatched zlib.
244 - Added a SECURITY.md file.
246 ### DEVELOPER RELATED:
248 - Made it easier to write rsync tests that diff the output while also checking
249 the status code, and used the idiom to improve the existing tests. (See the
250 `checkdiff` and `checkdiff2` idioms in the `testsuite/*.test` files.
252 - The packaging scripts & related python lib got some minor enhancements.
256 - Use setenv() instead of putenv() when it is available.
258 - Improve the logic in compat.c so that we don't need to try to remember to
259 sprinkle `!local_server` exceptions throughout the protocol logic.
261 - One more C99 Flexible Array improvement (started in the last release) and
262 make use of the C99 `%zd` format string when printing size_t values (when
265 - Use mallinfo2() instead of mallinfo(), when available.
267 ------------------------------------------------------------------------------
269 # NEWS for rsync 3.2.3 (6 Aug 2020)
271 ## Changes in this version:
275 - Fixed a bug in the xattr code that was freeing the wrong object when trying
276 to cleanup the xattr list.
278 - Fixed a bug in the xattr code that was not leaving room for the "rsync."
279 prefix in some instances where it needed to be added.
281 - Restored the ability to use [`--bwlimit=0`](rsync.1#opt) to specify no
282 bandwidth limit. (It was accidentally broken in 3.2.2.)
284 - Fixed a bug when combining [`--delete-missing-args`](rsync.1#opt) with
285 [`--no-implied-dirs`](rsync.1#opt) & [`-R`](rsync.1#opt) where rsync might
286 create the destination path of a missing arg. The code also avoids some
287 superfluous warnings for nested paths of removed args.
289 - Fixed an issue where hard-linked devices could cause the rdev_major value to
290 get out of sync between the sender and the receiver, which could cause a
291 device to get created with the wrong major value in its major,minor pair.
293 - Rsync now complains about a missing [`--temp-dir`](rsync.1#opt) before
294 starting any file transfers.
296 - A completely empty source arg is now a fatal error. This doesn't change
297 the handling of implied dot-dir args such as "localhost:" and such.
301 - Allow [`--max-alloc=0`](rsync.1#opt) to specify no limit to the alloc sanity
304 - Allow [`--block-size=SIZE`](rsync.1#opt) to specify the size using units
307 - The name of the id-0 user & group are now sent to the receiver along with
308 the other user/group names in the transfer (instead of assuming that both
309 sides have the same id-0 names).
311 - Added the [`--stop-after`](rsync.1#opt) and [`--stop-at`](rsync.1#opt)
312 options (with a [`--time-limit`](rsync.1#opt) alias for `--stop-after`).
313 This is an enhanced version of the time-limit patch from the patches repo.
315 - Added the [`name converter`](rsyncd.conf.5#opt) daemon parameter to make it
316 easier to convert user & group names inside a chrooted daemon module. This
317 is based on the nameconverter patch with some improvements, including a
318 tweak to the request protocol (so if you used this patch in the past, be
319 sure to update your converter script to use newlines instead of null chars).
321 - Added [`--crtimes`](rsync.1#opt) (`-N`) option for preserving the file's
322 create time (I believe that this is macOS only at the moment).
324 - Added [`--mkpath`](rsync.1#opt) option to tell rsync that it should create a
325 non-existing path component of the destination arg.
327 - Added [`--stderr=errors|all|client`](rsync.1#opt) to replace the
328 `--msgs2stderr` and `--no-msgs2stderr` options (which are still accepted).
329 The default use of stderr was changed to be `--stderr=errors` where all the
330 processes that have stderr available output directly to stderr, which should
331 help error messages get to the user more quickly, especially when doing a
332 push (which includes local copying). This also allows rsync to exit quickly
333 when a receiver failure occurs, since rsync doesn't need to try to keep the
334 connection alive long enough for the fatal error to go from the receiver to
335 the generator to the sender. The old default can be requested via
336 `--stderr=client`. Also changed is that a non-default stderr mode is
337 conveyed to the remote rsync (using the older option names) instead of
338 requiring the user to use [`--remote-option`](rsync.1#opt) (`-M`) to tell
339 the remote rsync what to do.
341 - Added the ability to specify "@netgroup" names to the [`hosts
342 allow`](rsyncd.conf.5#opt) and [`hosts deny`](rsyncd.conf.5#opt) daemon
343 parameters. This is a finalized version of the netgroup-auth patch from the
346 - Rsync can now hard-link symlinks on FreeBSD due to it making use of the
347 linkat() function when it is available.
349 - Output file+line info on out-of-memory & overflow errors while also avoiding
350 the output of alternate build-dir path info that is not useful to the user.
352 - Change configure to know that Cygwin supports Linux xattrs.
354 - Improved the testsuite on FreeBSD & Cygwin.
356 - Added some compatibility code for HPE NonStop platforms.
358 - Improved the INSTALL.md info.
360 - Added a few more suffixes to the default skip-compress list.
362 - Improved configure's error handling to notify about several issues at once
363 instead of one by one (for the newest optional features).
367 - Use a simpler overflow check idiom in a few spots.
369 - Use a C99 Flexible Array for a trailing variable-size filename in a struct
370 (with a fallback to the old 1-char string kluge for older compilers).
372 ------------------------------------------------------------------------------
374 # NEWS for rsync 3.2.2 (4 Jul 2020)
376 ## Changes in this version:
380 - Avoid a crash when a daemon module enables `transfer logging` without
381 setting a `log format` value.
383 - Fixed installing rsync-ssl script from an alternate build dir.
385 - Fixed the updating of configure.sh from an alternate build dir.
387 - Apple requires the asm function name to begin with an underscore.
389 - Avoid a test failure in the daemon test when `--atimes` is disabled.
393 - Allow the server side to restrict checksum & compression choices via the
394 same environment variables the client uses. The env vars can be divided
395 into "client list & server list" by the "`&`" char or the same list can
398 - Simplify how the negotiation environment variables apply when interacting
399 with an older rsync and also when a list contains only invalid names.
401 - Do not allow a negotiated checksum or compression choice of "none" unless
402 the user authorized it via an environment variable or command-line option.
404 - Added the `--max-alloc=SIZE` option to be able to override the memory
405 allocator's sanity-check limit. It defaults to 1G (as before) but the error
406 message when exceeding it specifically mentions the new option so that you
407 can differentiate an out-of-memory error from a failure of this limit. It
408 also allows you to specify the value via the RSYNC_MAX_ALLOC environment
411 - Add the "open atime" daemon parameter to allow a daemon to always enable or
412 disable the use of O_NOATIME (the default is to let the user control it).
414 - The default systemd config was changed to remove the `ProtectHome=on`
415 setting since rsync is often used to serve files in /home and /root and this
416 seemed a bit too strict. Feel free to use `systemctl edit rsync` to add
417 that restriction (or maybe `ProtectHome=read-only`), if you like. See the
418 3.2.0 NEWS for the other restrictions that were added compared to 3.1.3.
420 - The memory allocation functions now automatically check for a failure and
421 die when out of memory. This eliminated some caller-side check-and-die
422 code and added some missing sanity-checking of allocations.
424 - Put optimizations into their own list in the `--version` output.
426 - Improved the manpage a bit more.
428 ### PACKAGING RELATED:
430 - Prepared the checksum code for an upcoming xxHash release that provides new
431 XXH3 (64-bit) & XXH128 (128-bit) checksum routines. These will not be
432 compiled into rsync until the xxhash v0.8.0 include files are installed on
433 the build host, and that release is a few weeks away at the time this was
434 written. So, if it's now the future and you have packaged and installed
435 xxhash-0.8.0-devel, a fresh rebuild of rsync 3.2.2 will give you the new
436 checksum routines. Just make sure that the new rsync package depends on
439 ### DEVELOPER RELATED:
441 - Moved the version number out of configure.ac into its own version.h file so
442 that we don't need to reconfigure just because the version number changes.
444 - Moved the daemon parameter list into daemon-parm.txt so that an awk script
445 can create the interrelated structs and accessors that loadparm.c needs.
447 ------------------------------------------------------------------------------
449 # NEWS for rsync 3.2.1 (22 Jun 2020)
451 ## Changes in this version:
455 - Fixed a potential build issue with the MD5 assembly-language code by
456 removing some non-portable directives.
458 - Use the preprocessor with the asm file to ensure that if the code is
459 unneeded, it doesn't get built.
461 - Avoid the stack getting set to executable when including the asm code.
463 - Some improvements in the SIMD configure testing to try to avoid build
464 issues, such as avoiding a clang++ core dump when `-g` is combined with
465 `-O2`. Note that clang++ is quite buggy in this area, and it does still
466 crash for some folks, so just use `--disable-simd` if you need to avoid
467 their buggy compiler (since the configure test is apparently not finding
468 all the compilers that will to crash and burn).
470 - Fixed an issue in the md2man script when building from an alternate dir.
472 - Disable `--atimes` on macOS (it apparently just ignores the atime change).
476 - The use of `--backup-dir=STR` now implies `--backup`.
478 - Added `--zl=NUM` as a short-hand for `--compress-level=NUM`.
480 - Added `--early-input=FILE` option that allows the client to send some
481 data to a daemon's (optional) "early exec" script on its stdin.
483 - Mention atimes in the capabilities list that `--version` outputs.
485 - Mention either "default protect-args" or "optional protect-args" in the
486 `--version` capabilities depending on how rsync was configured.
488 - Some info on optimizations is now elided from the `--version` capabilities
489 since they aren't really user-facing capabilities. You can still see the
490 info (plus the status of a couple extra optimizations) by repeating the
491 `--version` option (e.g. `-VV`).
493 - Updated various URLs to be https instead of http.
495 - Some documentation improvements.
497 ### PACKAGING RELATED:
499 - If you had to use `--disable-simd` for 3.2.0, you might want to try removing
500 that and see if it will succeed or auto-disable. Some buggy clang++
501 compilers are still not auto disabled, though.
503 - The MD5 asm code is now under its own configure flag (not shared with the
504 SIMD setting), so if you have any issues compiling it, re-run configure with
507 - Merged the OLDNEWS.md file into NEWS.md.
509 ------------------------------------------------------------------------------
511 # NEWS for rsync 3.2.0 (19 Jun 2020)
513 ## Changes in this version:
517 - Avoid a potential out-of-bounds read in daemon mode if argc can be made to
520 - Fix the default list of skip-compress files for non-daemon transfers.
522 - Fix xattr filter rules losing an 'x' attribute in a non-local transfer.
524 - Avoid an error when a check for a potential fuzzy file happens to reference
527 - Make the atomic-rsync helper script have a more consistent error-exit.
529 - Make sure that a signal handler's use of exit_cleanup() calls `_exit()`
532 - Various zlib fixes, including security fixes for CVE-2016-9843,
533 CVE-2016-9842, CVE-2016-9841, and CVE-2016-9840.
535 - Fixed an issue with `--remove-source-files` not removing a source symlink
536 when combined with `--copy-links`.
538 - Fixed a bug where the daemon would fail to write early fatal error messages
539 to the client, such as refused or unknown command-line options.
541 - Fixed the block-size validation logic when dealing with older protocols.
543 - Some rrsync fixes and enhancements to handle the latest options.
545 - Fixed a problem with the `--link-dest`|`--copy-dest` code when `--xattrs`
546 was specified along with multiple alternate-destination directories (it
547 could possibly choose a bad file match while trying to find a better xattr
550 - Fixed a couple bugs in the handling of files with the `--sparse` option.
552 - Fixed a bug in the writing of the batch.sh file (w/`--write-batch`) when the
553 source & destination args were not last on the command-line.
555 - Avoid a hang when an overabundance of messages clogs up all the I/O buffers.
557 - Fixed a mismatch in the RSYNC_PID values put into the environment of
558 `pre-xfer exec` and a `post-xfer exec`.
560 - Fixed a crash in the `--iconv` code.
562 - Fixed a rare crash in the popt_unalias() code.
566 - The default systemd config was made stricter by default. For instance,
567 `ProtectHome=on` (which hides content in /root and /home/USER dirs),
568 `ProtectSystem=full` (which makes /usr, /boot, & /etc dirs read-only), and
569 `PrivateDevices=on` (which hides devices). You can override any of these
570 using the standard `systemctl edit rsync` and add one or more directives
571 under a `[Service]` heading (and restart the rsync service).
573 - Various checksum enhancements, including the optional use of openssl's MD4 &
574 MD5 checksum algorithms, some x86-64 optimizations for the rolling checksum,
575 some x86-64 optimizations for the (non-openssl) MD5 checksum, the addition
576 of xxHash checksum support, and a negotiation heuristic that ensures that it
577 is easier to add new checksum algorithms in the future. The environment
578 variable `RSYNC_CHECKSUM_LIST` can be used to customize the preference order
579 of the negotiation, or use `--checksum-choice` (`--cc`) to force a choice.
581 - Various compression enhancements, including the addition of zstd and lz4
582 compression algorithms and a negotiation heuristic that picks the best
583 compression option supported by both sides. The environment variable
584 `RSYNC_COMPRESS_LIST` can be used to customize the preference order of the
585 negotiation, or use `--compress-choice` (`--zc`) to force a choice.
587 - Added a `--debug=NSTR` option that outputs details of the new negotiation
588 strings (for checksums and compression). The first level just outputs the
589 result of each negotiation on the client, level 2 outputs the values of the
590 strings that were sent to and received from the server, and level 3 outputs
591 all those values on the server side too (when the server was given the debug
594 - The `--debug=OPTS` command-line option is no longer auto-forwarded to the
595 remote rsync which allows for the client and server to have different levels
596 of debug specified. This also allows for newer debug options to be
597 specified, such as using `--debug=NSTR` to see the negotiated hash result,
598 without having the command fail if the server version is too old to handle
599 that debug item. Use `-M--debug=OPTS` to send the options to the remote side.
601 - Added the `--atimes` option based on the long-standing patch (just with some
602 fixes that the patch has been needing).
604 - Added `--open-noatime` option to open files using `O_NOATIME`.
606 - Added the `--write-devices` option based on the long-standing patch.
608 - Added openssl & preliminary gnutls support to the rsync-ssl script, which is
609 now installed by default. This was unified with the old stunnel-rsync
610 helper script to simplify packaging. Note that the script accepts the use
611 of `--type=gnutls` for gnutls testing, but does not look for gnutls-cli on
612 the path yet. The use of `--type=gnutls` will not work right until
613 gnutls-cli no longer drops data.
615 - Rsync was enhanced to set the `RSYNC_PORT` environment variable when running
616 a daemon-over-rsh script. Its value is the user-specified port number (set
617 via `--port` or an rsync:// URL) or 0 if the user didn't override the port.
619 - Added the `proxy protocol` daemon parameter that allows your rsyncd to know
620 the real remote IP when it is setup behind a proxy.
622 - Added negated matching to the daemon's `refuse options` setting by using
623 match strings that start with a `!` (such as `!compress*`). This lets you
624 refuse all options except for a particular approved list, for example. It
625 also lets rsync refuse certain options by default (such as `write-devices`)
626 while allowing the config to override that, as desired.
628 - Added the `early exec` daemon parameter that runs a script before the
629 transfer parameters are known, allowing some early setup based on module
632 - Added status output in response to a signal (via both SIGINFO & SIGVTALRM).
634 - Added `--copy-as=USER` option to give some extra security to root-run rsync
635 commands into/from untrusted directories (such as backups and restores).
637 - When resuming the transfer of a file in the `--partial-dir`, rsync will now
638 update that partial file in-place instead of creating yet another tmp file
639 copy. This requires both sender & receiver to be at least v3.2.0.
641 - Added support for `RSYNC_SHELL` & `RSYNC_NO_XFER_EXEC` environment variables
642 that affect the early, pre-xfer, and post-xfer exec rsync daemon parameters.
644 - Optimize the `--fuzzy --fuzzy` heuristic to avoid the fuzzy directory scan
645 until all other basis-file options are exhausted (such as `--link-dest`).
647 - Have the daemon log include the normal-exit sent/received stats when the
648 transfer exited with an error when possible (i.e. if it is the sender).
650 - The daemon now locks its pid file (when configured to use one) so that it
651 will not fail to start when the file exists but no daemon is running.
653 - Various manpage improvements, including some html representations (that
654 aren't installed by default).
656 - Made `-V` the short option for `--version` and improved its information.
658 - Pass the `-4` or `-6` option to the ssh command, making it easier to type
659 than `--rsh='ssh -4'` (or the `-6` equivalent).
661 - Added example config for rsyncd SSL proxy configs to rsyncd.conf.
663 - More errors messages now mention if the error is coming from the sender or
666 ### PACKAGING RELATED:
668 - Add installed bash script: /usr/bin/rsync-ssl
670 - Add installed manpage: /usr/man/man1/rsync-ssl.1
672 - Tweak auxiliary doc file names, such as: README.md, INSTALL.md, & NEWS.md.
674 - The rsync-ssl script wants to run openssl or stunnel4, so consider adding a
675 dependency for one of those options (though it's probably fine to just let
676 it complain about being unable to find the program and let the user decide
677 if they want to install one or the other).
679 - If you packaged rsync + rsync-ssl + rsync-ssl-daemon as separate packages,
680 the rsync-ssl package is now gone (rsync-ssl should be considered to be
681 mainstream now that Samba requires SSL for its rsync daemon).
683 - Add _build_ dependency for liblz4-dev, libxxhash-dev, libzstd-dev, and
684 libssl-dev. These development libraries will give rsync extra compression
685 algorithms, extra checksum algorithms, and allow use of openssl's crypto
686 lib for (potentially) faster MD4/MD5 checksums.
688 - Add _build_ dependency for g++ or clang++ on x86_64 systems to enable the
689 SIMD checksum optimizations.
691 - Add _build_ dependency for _either_ python3-cmarkcfm or python3-commonmark
692 to allow for patching of manpages or building a git release. This is not
693 required for a release-tar build, since it comes with pre-built manpages.
694 Note that cmarkcfm is faster than commonmark, but they generate the same
695 data. The commonmark dependency is easiest to install since it's native
696 python, and can even be installed via `pip3 install --user commonmark` if
697 you want to just install it for the build user.
699 - Remove yodl _build_ dependency (if it was even listed before).
701 ### DEVELOPER RELATED:
703 - Silenced some annoying warnings about major() & minor() by improving an
704 autoconf include-file check.
706 - Converted the manpages from yodl to markdown. They are now processed via a
707 simple python3 script using the cmarkgfm **or** commonmark library. This
708 should make it easier to package rsync, since yodl is rather obscure.
710 - Improved some configure checks to work better with strict C99 compilers.
712 - Some perl building/packaging scripts were recoded into awk and python3.
714 - Some defines in byteorder.h were changed into static inline functions that
715 will help to ensure that the args don't get evaluated multiple times on
716 "careful alignment" hosts.
718 - Some code typos were fixed (as pointed out by a Fossies run).
720 ------------------------------------------------------------------------------
722 # NEWS for rsync 3.1.3 (28 Jan 2018)
724 ## Changes in this version:
728 - Fixed a buffer overrun in the protocol's handling of xattr names and ensure
729 that the received name is null terminated.
731 - Fix an issue with `--protect-args` where the user could specify the arg in the
732 protected-arg list and short-circuit some of the arg-sanitizing code.
736 - Don't output about a new backup dir without appropriate info verbosity.
738 - Fixed some issues with the sort functions in the rsyncstats script (in the
741 - Added a way to specify daemon config lists (e.g. users, groups, etc) that
742 contain spaces (see `auth users` in the latest rsyncd.conf manpage).
744 - If a backup fails (e.g. full disk) rsync exits with an error.
746 - Fixed a problem with a doubled `--fuzzy` option combined with `--link-dest`.
748 - Avoid invalid output in the summary if either the start or end time had an
751 - We don't allow a popt alias to affect the `--daemon` or `--server` options.
753 - Fix daemon exclude code to disallow attribute changes in addition to
754 disallowing transfers.
756 - Don't force nanoseconds to match if a non-transferred, non-checksummed file
757 only passed the quick-check w/o comparing nanoseconds.
761 - Added the ability for rsync to compare nanosecond times in its file-check
762 comparisons, and added support nanosecond times on Mac OS X.
764 - Added a short-option (`-@`) for `--modify-window`.
766 - Added the `--checksum-choice=NAME[,NAME]` option to choose the checksum
769 - Added hashing of xattr names (with using `-X`) to improve the handling of
770 files with large numbers of xattrs.
772 - Added a way to filter xattr names using include/exclude/filter rules (see
773 the `--xattrs` option in the manpage for details).
775 - Added `daemon chroot|uid|gid` to the daemon config (in addition to the old
776 chroot|uid|gid settings that affect the daemon's transfer process).
778 - Added `syslog tag` to the daemon configuration.
780 - Some manpage improvements.
782 ### DEVELOPER RELATED:
784 - Tweak the `make` output when yodl isn't around to create the manpages.
786 - Changed an obsolete autoconf compile macro.
788 - Support newer yodl versions when converting manpages.
790 ------------------------------------------------------------------------------
792 # NEWS for rsync 3.1.2 (21 Dec 2015)
794 ## Changes in this version:
798 - Make sure that all transferred files use only path names from inside the
799 transfer. This makes it impossible for a malicious sender to try to make the
800 receiver use an unsafe destination path for a transferred file, such as a
805 - Change the checksum seed order in the per-block checksums. This prevents
806 someone from trying to create checksum blocks that match in sum but not
809 - Fixed a with the per-dir filter files (using `-FF`) that could trigger an
812 - Only skip `set_modtime()` on a transferred file if the time is exactly
815 - Don't create an empty backup dir for a transferred file that doesn't exist
818 - Fixed a bug where `--link-dest` and `--xattrs` could cause rsync to exit if
819 a filename had a matching dir of the same name in the alt-dest area.
821 - Allow more than 32 group IDs per user in the daemon's gid=LIST config.
823 - Fix the logging of %b & %c via `--log-file` (daemon logging was already
824 correct, as was `--out-format='%b/%c'`).
826 - Fix erroneous acceptance of `--info=5` & `--debug=5` (an empty flag name is
831 - Added `(DRY RUN)` info to the `--debug=exit` output line.
833 - Use usleep() for our msleep() function if it is available.
835 - Added a few extra long-option names to rrsync script, which will make
838 - Made configure choose to use Linux xattrs on NetBSD (rather than not
841 - Added `-wo` (write-only) option to rrsync support script.
843 - Misc. manpage tweaks.
845 ### DEVELOPER RELATED:
847 - Fixed a bug with the Makefile's use of `INSTALL_STRIP`.
849 - Improve a test in the suite that could get an erroneous timestamp error.
851 - Tweaks for newer versions of git in the packaging tools.
853 - Improved the m4 generation rules and some autoconf idioms.
855 ------------------------------------------------------------------------------
857 # NEWS for rsync 3.1.1 (22 Jun 2014)
859 ## Changes in this version:
863 - If the receiver gets bogus filenames from the sender (an unexpected leading
864 slash or a `..` infix dir), exit with an error. This prevents a malicious
865 sender from trying to inject filenames that would affect an area outside the
866 destination directories.
868 - Fixed a failure to remove the partial-transfer temp file when interrupted
869 (and rsync is not saving the partial files).
871 - Changed the chown/group/xattr-set order to avoid losing some security-
872 related xattr info (that would get cleared by a chown).
874 - Fixed a bug in the xattr-finding code that could make a non-root-run
875 receiver not able to find some xattr numbers.
877 - Fixed a bug in the early daemon protocol where a timeout failed to be
878 honored (e.g. if the remote side fails to send us the initial protocol
881 - Fixed unintended inclusion of commas in file numbers in the daemon log.
883 - We once again send the 'f' sub-flag (of `-e`) to the server side so it knows
884 that we can handle incremental-recursion directory errors properly in older
887 - Fixed an issue with too-aggressive keep-alive messages causing a problem for
888 older rsync versions early in the transfer.
890 - Fixed an incorrect message about backup-directory-creation when using
891 `--dry-run` and the backup dir is not an absolute path.
893 - Fixed a bug where a failed deletion and/or a failed sender-side removal
894 would not affect the exit code.
896 - Fixed a bug that caused a failure when combining `--delete-missing-args`
897 with `--xattrs` and/or `--acls`.
899 - Fixed a strange `dir_depth` assertion error that was caused by empty-dir
900 removals and/or duplicate files in the transfer.
902 - Fixed a problem with `--info=progress2`'s output stats where rsync would
903 only update the stats at the end of each file's transfer. It now uses the
904 data that is flowing for the current file, making the stats more accurate
907 - Fixed an itemize bug that affected the combo of `--link-dest`, `-X`, and
910 - Fixed a problem with delete messages not appearing in the log file when the
911 user didn't use `--verbose`.
913 - Improve chunked xattr reading for OS X.
915 - Removed an attempted hard-link xattr optimization that was causing a
916 transfer failure. This removal is flagged in the compatibility code, so if a
917 better fix can be discovered, we have a way to flip it on again.
919 - Fixed a bug when the receiver is not configured to be able to hard link
920 symlimks/devices/special-file items but the sender sent some of these items
921 flagged as hard-linked.
923 - We now generate a better error if the buffer overflows in `do_mknod()`.
925 - Fixed a problem reading more than 16 ACLs on some OSes.
927 - Fixed the reading of the secrets file to avoid an infinite wait when the
930 - Fixed a parsing problem in the `--usermap`/`--groupmap` options when using
933 - Switched Cygwin back to using socketpair `pipes` to try to speed it up.
935 - Added knowledge of a few new options to rrsync.
939 - Tweaked the temp-file naming when `--temp-dir=DIR` is used: the temp-file
940 names will not get a '.' prepended.
942 - Added support for a new-compression idiom that does not compress all the
943 matching data in a transfer. This can help rsync to use less cpu when a
944 transfer has a lot of matching data, and also makes rsync compatible with a
945 non-bundled zlib. See the `--new-compress` and `--old-compress` options in
948 - Added the rsync-no-vanished shell script. (See the support dir.)
950 - Made configure more prominently mention when we failed to find yodl (in case
951 the user wants to be able to generate manpages from `*.yo` files).
953 - Have manpage mention how a daemon's max-verbosity setting affects info and
954 debug options. Also added more clarification on backslash removals for
955 excludes that contain wildcards.
957 - Have configure check if for the attr lib (for getxattr) for those systems
958 that need to link against it explicitly.
960 - Change the early dir-creation logic to only use that idiom in an
961 inc-recursive copy that is preserving directory times. e.g. using
962 `--omit-dir-times` will avoid these early directories being created.
964 - Fix a bug in `cmp_time()` that would return a wrong result if the 2 times
965 differed by an amount greater than what a `time_t` can hold.
967 ### DEVELOPER RELATED:
969 - We now include an example systemd file (in packaging/systemd).
971 - Tweaked configure to make sure that any intended use of the included popt
972 and/or zlib code is put early in the CFLAGS.
974 ------------------------------------------------------------------------------
976 # NEWS for rsync 3.1.0 (28 Sep 2013)
978 ## Changes in this version:
982 - The protocol number was changed to 31.
986 - Output numbers in 3-digit groups by default (e.g. 1,234,567). See the
987 `--human-readable` option for a way to turn it off. See also the daemon's
988 `log format` parameter and related command-line options (including
989 `--out-format`) for a modifier that can be used to request digit-grouping or
990 human-readable output in log escapes. (Note that log output is unchanged by
993 - The `--list-only` option is now affected by the `--human-readable` setting.
994 It will display digit groupings by default, and unit suffixes if higher
995 levels of readability are requested. Also, the column width for the size
996 output has increased from 11 to 14 characters when human readability is
997 enabled. Use `--no-h` to get the old-style output and column size.
999 - The output of the `--progress` option has changed: the string `xfer` was
1000 shortened to `xfr`, and the string `to-check` was shortened to `to-chk`,
1001 both designed to make room for the (by default) wider display of file size
1002 numbers without making the total line-length longer. Also, when incremental
1003 recursion is enabled, the string `ir-chk` will be used instead of `to-chk`
1004 up until the incremental-recursion scan is done, letting you know that the
1005 value to check and the total value will still be increasing as new files are
1008 - Enhanced the `--stats` output: 1) to mention how many files were created
1009 (protocol >= 28), 2) to mention how many files were deleted (a new line for
1010 protocol 31, but only output when `--delete` is in effect), and 3) to follow
1011 the file-count, created-count, and deleted-count with a subcount list that
1012 shows the counts by type. The wording of the transferred count has also
1013 changed so that it is clearer that it is only a count of regular files.
1017 - Fixed a bug in the iconv code when EINVAL or EILSEQ is returned with a full
1020 - Fixed some rare bugs in `--iconv` processing that might cause a multi-byte
1021 character to get translated incorrectly.
1023 - Fixed a bogus `vanished file` error if some files were specified with `./`
1024 prefixes and others were not.
1026 - Fixed a bug in `--sparse` where an extra gap could get inserted after a
1029 - Changed the way `--progress` overwrites its prior output in order to make it
1030 nearly impossible for the progress to get overwritten by an error.
1032 - Improved the propagation of abnormal-exit error messages. This should help
1033 the client side to receive errors from the server when it is exiting
1034 abnormally, and should also avoid dying with an `connection unexpectedly
1035 closed` exit when the closed connection is really expected.
1037 - The sender now checks each file it plans to remove to ensure that it hasn't
1038 changed from the first stat's info. This helps to avoid losing file data
1039 when the user is not using the option in a safe manner.
1041 - Fixed a data-duplication bug in the compress option that made compression
1042 less efficient. This improves protocol 31 onward, while behaving in a
1043 compatible (buggy) manner with older rsync protocols.
1045 - When creating a temp-file, rsync is now a bit smarter about it dot-char
1046 choices, which can fix a problem on OS X with names that start with `..`.
1048 - Rsync now sets a cleanup flag for `--inplace` and `--append` transfers that
1049 will flush the write buffer if the transfer aborts. This ensures that more
1050 received data gets written out to the disk on an aborted transfer (which is
1051 quite helpful on a slow, flaky connection).
1053 - The reads that `map_ptr()` now does are aligned on 1K boundaries. This helps
1054 some filesystems and/or files that don't like unaligned reads.
1056 - Fix an issue in the msleep() function if time jumps backwards.
1058 - Fix daemon-server module-name splitting bug where an arg would get split
1059 even if `--protect-args` was used.
1063 - Added the `--remote-option=OPT` (`-M OPT`) command-line option that is
1064 useful for things like sending a remote `--log-file=FILE` or `--fake-super`
1067 - Added the `--info=FLAGS` and `--debug=FLAGS` options to allow finer-grained
1068 control over what is output. Added an extra type of `--progress` output
1069 using `--info=progress2`.
1071 - The `--msgs2stderr` option can help with debugging rsync by allowing the
1072 debug messages to get output to stderr rather than travel via the socket
1075 - Added the `--delete-missing-args` and `--ignore-missing-args` options to
1076 either delete or ignore user-specified files on the receiver that are
1077 missing on the sender (normally the absence of user-specified files
1078 generates an error).
1080 - Added a `T` (terabyte) category to the `--human-readable` size suffixes.
1082 - Added the `--usermap`/`--groupmap`/`--chown` options for manipulating file
1083 ownership during the copy.
1085 - Added the `%C` escape to the log-output handling, which will output the MD5
1086 checksum of any transferred file, or all files if `--checksum` was specified
1087 (when protocol 30 or above is in effect).
1089 - Added the `reverse lookup` parameter to the rsync daemon config file to
1090 allow reverse-DNS lookups to be disabled.
1092 - Added a forward-DNS lookup for the daemon's hosts allow/deny config. Can be
1093 disabled via `forward lookup` parameter (defaults to enabled).
1095 - Added a way for more than one group to be specified in the daemon's config
1096 file, including a way to specify that you want all of the specified user's
1097 groups without having to name them. Also changed the daemon to complain
1098 about an inability to set explicitly-specified uid/gid values, even when not
1099 run by a super-user.
1101 - The daemon now tries to send the user the error messages from the pre-xfer
1102 exec script when it fails.
1104 - Improved the use of alt-dest options into an existing hierarchy of files: If
1105 a match is found in an alt-dir, it takes precedence over an existing file.
1106 (We'll need to wait for a future version before attribute-changes on
1107 otherwise unchanged files are safe when using an existing hierarchy.)
1109 - Added per-user authorization options and group-authorization support to the
1110 daemon's `auth users` parameter.
1112 - Added a way to reference environment variables in a daemon's config file
1113 (using %VAR% references).
1115 - When replacing a non-dir with a symlink/hard-link/device/special-file, the
1116 update should now be done in an atomic manner.
1118 - Avoid re-sending xattr info for hard-linked files w/the same xattrs
1121 - The backup code was improved to use better logic maintaining the backup
1122 directory hierarchy. Also, when a file is being backed up, rsync tries to
1123 hard-link it into place so that the upcoming replacement of the destination
1124 file will be atomic (for the normal, non-inplace logic).
1126 - Added the ability to synchronize nanosecond modified times.
1128 - Added a few more default suffixes for the `dont compress` settings.
1130 - Added the checking of the `RSYNC_PROTECT_ARGS` environment variable to allow
1131 the default for the `--protect-args` command-line option to be overridden.
1133 - Added the `--preallocate` command-line option.
1135 - Allow `--password-file=-` to read the password from stdin (filename `-`).
1137 - Rsync now comes packaged with an rsync-ssl helper script that can be used to
1138 contact a remote rsync daemon using a piped-stunnel command. It also
1139 includes an stunnel config file to run the server side to support ssl daemon
1140 connections. See the packaging/lsb/rsync.spec file for one way to package
1141 the resulting files. (Suggestions for how to make this even easier to
1142 install & use are welcomed.)
1144 - Improved the speed of some `--inplace` updates when there are lots of
1145 identical checksum blocks that end up being unusable.
1147 - Added the `--outbuf=N|L|B` option for choosing the output buffering.
1149 - Repeating the `--fuzzy` option now causes the code to look for fuzzy matches
1150 inside alt-dest directories too.
1152 - The `--chmod` option now supports numeric modes, e.g. `--chmod=644,D755`
1154 - Added some Solaris xattr code.
1156 - Made an rsync daemon (the listening process) exit with a 0 status when it
1157 was signaled to die. This helps launchd.
1159 - Improved the `RSYNC_*` environment variables for the pre-xfer exec script:
1160 when a daemon is sent multiple request args, they are now joined into a
1161 single return value (separated by spaces) so that the `RSYNC_REQUEST`
1162 environment variable is accurate for any `pre-xfer exec`. The values in
1163 `RSYNC_ARG#` vars are no longer truncated at the `.` arg (prior to the
1164 request dirs/files), so that all the requested values are also listed
1165 (separately) in `RSYNC_ARG#` variables.
1169 - Added an `instant-rsyncd` script to the support directory, which makes it
1170 easy to configure a simple rsync daemon in the current directory.
1172 - Added the `mapfrom` and `mapto` scripts to the support directory, which
1173 makes it easier to do user/group mapping in a local transfer based on
1174 passwd/group files from another machine.
1176 - There's a new, improved version of the lsh script in the support dir: it's
1177 written in perl and supports `-u` without resorting to using sudo (when run
1178 as root). The old shell version is now named lsh.sh.
1180 - There is a helper script named rsync-slash-strip in the support directory
1181 for anyone that wants to change the way rsync handles args with trailing
1182 slashes. (e.g. arg/ would get stripped to arg while arg/. would turn into
1187 - The I/O code was rewritten to be simpler and do bigger buffered reads over
1188 the socket. The I/O between the receiver and the generator was changed to be
1189 standard multiplexed-I/O (like that over the socket).
1191 - The sender tries to use any dead time while the generator is looking for
1192 files to transfer in order to do sender-side directory scanning in a more
1195 - A daemon can now inform a client about a daemon-configured timeout value so
1196 that the client can assist in the keep-alive activity (protocol 31).
1198 - The filter code received some refactoring to make it more extendable, to
1199 read better, and do better sanity checking.
1201 - Really big numbers are now output using our own big-num routine rather than
1202 casting them to a double and using a %.0f conversion.
1204 - The `pool_alloc` library has received some minor improvements in alignment
1207 - Added `init_stat_x()` function to avoid duplication of acl/xattr init code.
1209 - The included zlib was upgraded from 1.2.3 to 1.2.8.
1211 - Rsync can now be compiled to use an unmodified zlib library instead of the
1212 tweaked one that is included with rsync. This will eventually become the
1213 default, at which point we'll start the countdown to removing the included
1214 zlib. Until then, feel free to configure using:
1216 ./configure `--with-included-zlib=no`
1218 ### DEVELOPER RELATED:
1220 - Added more conditional debug output.
1222 - Fixed some build issues for Android and Minix.
1224 ------------------------------------------------------------------------------
1226 # NEWS for rsync 3.0.9 (23 Sep 2011)
1228 ## Changes in this version:
1232 - Fix a crash bug in checksum scanning when `--inplace` is used.
1234 - Fix a hang if a hard-linked file cannot be opened by the sender (e.g. if it
1235 has no read permission).
1237 - Fix preservation of a symlink's system xattrs (e.g. selinux) on Linux.
1239 - Fix a memory leak in the xattr code.
1241 - Fixed a bug with `--delete-excluded` when a filter merge file has a rule
1242 that specifies a receiver-only side restriction.
1244 - Fix a bug with the modifying of unwritable directories.
1246 - Fix `--fake-super`'s interaction with `--link-dest` same-file comparisons.
1248 - Fix the updating of the `curr_dir` buffer to avoid a duplicate slash.
1250 - Fix the directory permissions on an implied dot-dir when using `--relative`
1251 (e.g. /outside/path/././send/path).
1253 - Fixed some too-long sleeping instances when using `--bwlimit`.
1255 - Fixed when symlink ownership difference-checking gets compiled into
1256 `unchanged_attrs()`.
1258 - Improved the socket-error reporting when multiple protocols fail.
1260 - Fixed a case where a socket error could reference just-freed memory.
1262 - Failing to use a password file that was specified on the command-line is now
1265 - Fix the non-root updating of directories that don't have the read and/or
1268 - Make daemon-excluded file errors more error-like.
1270 - Fix a compilation issue on older C compilers (due to a misplaced var
1273 - Make configure avoid finding socketpair on Cygwin.
1275 - Avoid trying to reference `SO_BROADCAST` if the OS doesn't support it.
1277 - Fix some issues with the post-processing of the manpages.
1279 - Fixed the user home-dir handling in the lsh script. (See the support dir.)
1281 - Some minor manpage improvements.
1283 ------------------------------------------------------------------------------
1285 # NEWS for rsync 3.0.8 (26 Mar 2011)
1287 ## Changes in this version:
1291 - Fixed two buffer-overflow issues: one where a directory path that is exactly
1292 MAXPATHLEN was not handled correctly, and one handling a `--backup-dir` that
1293 is extra extra large.
1295 - Fixed a data-corruption issue when preserving hard-links without preserving
1296 file ownership, and doing deletions either before or during the transfer
1297 (CVE-2011-1097). This fixes some assert errors in the hard-linking code, and
1298 some potential failed checksums (via `-c`) that should have matched.
1300 - Fixed a potential crash when an rsync daemon has a filter/exclude list and
1301 the transfer is using ACLs or xattrs.
1303 - Fixed a hang if a really large file is being processed by an rsync that
1304 can't handle 64-bit numbers. Rsync will now complain about the file being
1305 too big and skip it.
1307 - For devices and special files, we now avoid gathering useless ACL and/or
1308 xattr information for files that aren't being copied. (The un-copied files
1309 are still put into the file list, but there's no need to gather data that is
1310 not going to be used.) This ensures that if the user uses `--no-D`, that
1311 rsync can't possibly complain about being unable to gather extended
1312 information from special files that are in the file list (but not in the
1315 - Properly handle requesting remote filenames that start with a dash. This
1316 avoids a potential error where a filename could be interpreted as a (usually
1319 - Fixed a bug in the comparing of upper-case letters in file suffixes for
1322 - If an rsync daemon has a module configured without a path setting, rsync
1323 will now disallow access to that module.
1325 - If the destination arg is an empty string, it will be treated as a reference
1326 to the current directory (as 2.x used to do).
1328 - If rsync was compiled with a newer time-setting function (such as lutimes),
1329 rsync will fall-back to an older function (such as utimes) on a system where
1330 the newer function is not around. This helps to make the rsync binary more
1331 portable in mixed-OS-release situations.
1333 - Fixed a batch-file writing bug that would not write out the full set of
1334 compatibility flags that the transfer was using. This fixes a potential
1335 protocol problem for a batch file that contains a sender-side I/O error: it
1336 would have been sent in a way that the batch-reader wasn't expecting.
1338 - Some improvements to the hard-linking code to ensure that device-number
1339 hashing is working right, and to supply more information if the hard-link
1342 - The `--inplace` code was improved to not search for an impossible checksum
1343 position. The quadruple-verbose chunk[N] message will now mention when an
1344 inplace chunk was handled by a seek rather than a read+write.
1346 - Improved ACL mask handling, e.g. for Solaris.
1348 - Fixed a bug that prevented `--numeric-ids` from disabling the translation of
1349 user/group IDs for ACLs.
1351 - Fixed an issue where an xattr and/or ACL transfer that used an alt-dest
1352 option (e.g. `--link-dest`) could output an error trying to itemize the
1353 changes against the alt-dest directory's xattr/ACL info but was instead
1354 trying to access the not-yet-existing new destination directory.
1356 - Improved xattr system-error messages to mention the full path to the file.
1358 - The `--link-dest` checking for identical symlinks now avoids considering
1359 attribute differences that cannot be changed on the receiver.
1361 - Avoid trying to read/write xattrs on certain file types for certain OSes.
1362 Improved configure to set `NO_SYMLINK_XATTRS`, `NO_DEVICE_XATTRS`, and/or
1363 `NO_SPECIAL_XATTRS` defines in config.h.
1365 - Improved the unsafe-symlink errors messages.
1367 - Fixed a bug setting xattrs on new files that aren't user writable.
1369 - Avoid re-setting xattrs on a hard-linked file w/the same xattrs.
1371 - Fixed a bug with `--fake-super` when copying files and dirs that aren't user
1374 - Fixed a bug where a sparse file could have its last sparse block turned into
1375 a real block when rsync sets the file size (requires ftruncate).
1377 - If a temp-file name is too long, rsync now avoids truncating the name in the
1378 middle of adjacent high-bit characters. This prevents a potential filename
1379 error if the filesystem doesn't allow a name to contain an invalid
1380 multi-byte sequence.
1382 - If a muli-protocol socket connection fails (i.e., when contacting a daemon),
1383 we now report all the failures, not just the last one. This avoids losing a
1384 relevant error (e.g. an IPv4 connection-refused error) that happened before
1385 the final error (e.g. an IPv6 protocol-not-supported error).
1387 - Generate a transfer error if we try to call chown with a `-1` for a uid or a
1388 gid (which is not settable).
1390 - Fixed the working of `--force` when used with `--one-file-system`.
1392 - Fix the popt arg parsing so that an option that doesn't take an arg will
1393 reject an attempt to supply one (can configure `--with-included-popt` if
1394 your system's popt library doesn't yet have this fix).
1396 - A couple minor option tweaks to the rrsync script, and also some regex
1397 changes that make vim highlighting happier. (See the support dir.)
1399 - Fixed some issues in the mnt-excl script. (See the support dir.)
1401 - Various manpage improvements.
1405 - Added `.hg/` to the default cvs excludes (see `-C` & `--cvs-exclude`).
1407 ### DEVELOPER RELATED:
1409 - Use lchmod() whenever it is available (not just on symlinks).
1411 - A couple fixes to the `socketpair_tcp()` routine.
1413 - Updated the helper scripts in the packaging subdirectory.
1415 - Renamed configure.in to configure.ac.
1417 - Fixed configure's checking for iconv routines for newer OS X versions.
1419 - Fixed the testsuite/xattrs.test script on OS X.
1421 ------------------------------------------------------------------------------
1423 # NEWS for rsync 3.0.7 (31 Dec 2009)
1425 ## Changes in this version:
1429 - Fixed a bogus free when using `--xattrs` with `--backup`.
1431 - Avoid an error when `--dry-run` was trying to stat a prior hard-link file
1432 that hasn't really been created.
1434 - Fixed a problem with `--compress` (`-z`) where the receiving side could
1435 return the error "`inflate (token) returned -5`".
1437 - Fixed a bug where `--delete-during` could delete in a directory before it
1438 noticed that the sending side sent an I/O error for that directory (both
1439 sides of the transfer must be at least 3.0.7).
1441 - Improved `--skip-compress`'s error handling of bad character-sets and got
1442 rid of a lingering debug fprintf().
1444 - Fixed the daemon's conveyance of `io_error` value from the sender.
1446 - An rsync daemon use seteuid() (when available) if it used setuid().
1448 - Get the permissions right on a `--fake-super` transferred directory that
1449 needs more owner permissions to emulate root behavior.
1451 - An absolute-path filter rule (i.e. with a '/' modifier) no longer loses its
1452 modifier when sending the filter rules to the remote rsync.
1454 - Improved the "`--delete does not work without -r or -d`" message.
1456 - Improved rsync's handling of `--timeout` to avoid a weird timeout case where
1457 the sender could timeout even though it has recently written data to the
1458 socket (but hasn't read data recently, due to the writing).
1460 - Some misc manpage improvements.
1462 - Fixed the chmod-temp-dir testsuite on a system without /var/tmp.
1464 - Make sure that a timeout specified in the daemon's config is used as a
1465 maximum timeout value when the user also specifies a timeout.
1467 - Improved the error-exit reporting when rsync gets an error trying to cleanup
1468 after an error: the initial error is reported.
1470 - Improved configure's detection of IPv6 for Solaris and Cygwin.
1472 - The AIX sysacls routines will now return ENOSYS if ENOTSUP is missing.
1474 - Made our (only used if missing) getaddrinfo() routine use `inet_pton()`
1475 (which we also provide) instead of `inet_aton()`.
1477 - The exit-related debug messages now mention the program's role so it is
1478 clear who output what message.
1480 ### DEVELOPER RELATED:
1482 - Got rid of type-punned compiler warnings output by newer gcc versions.
1484 - The Makefile now ensures that proto.h will be rebuilt if config.h changes.
1486 - The testsuite no longer uses `id -u`, so it works better on Solaris.
1488 ------------------------------------------------------------------------------
1490 # NEWS for rsync 3.0.6 (8 May 2009)
1492 ## Changes in this version:
1496 - Fixed a `--read-batch` hang when rsync is reading a batch file that was
1497 created from an incremental-recursion transfer.
1499 - Fixed the daemon's socket code to handle the simultaneous arrival of
1500 multiple connections.
1502 - Fix `--safe-links`/`--copy-unsafe-links` to properly handle symlinks that
1503 have consecutive slashes in the value.
1505 - Fixed the parsing of an `[IPv6_LITERAL_ADDR]` when a USER@ is prefixed.
1507 - The sender now skips a (bogus) symlink that has a 0-length value, which
1508 avoids a transfer error in the receiver.
1510 - Fixed a case where the sender could die with a tag-0 error if there was an
1511 I/O during the sending of the file list.
1513 - Fixed the rrsync script to avoid a server-side problem when `-e` is at the
1514 start of the short options.
1516 - Fixed a problem where a vanished directory could turn into an exit code 23
1517 instead of the proper exit code 24.
1519 - Fixed the `--iconv` conversion of symlinks when doing a local copy.
1521 - Fixed a problem where `--one-file-system` was not stopping deletions on the
1522 receiving side when a mount-point directory did not match a directory in the
1525 - Fixed the dropping of an ACL mask when no named ACL values were present.
1527 - Fixed an ACL/xattr corruption issue where the `--backup` option could cause
1528 rsync to associate the wrong ACL/xattr information with received files.
1530 - Fixed the use of `--xattrs` with `--only-write-batch`.
1532 - Fixed the use of `--dry-run` with `--read-batch`.
1534 - Fixed configure's erroneous use of target.
1536 - Fixed configure's `--disable-debug` option.
1538 - Fixed a run-time issue for systems that can't find `iconv_open()` by adding
1539 the `--disable-iconv-open` configure option.
1541 - Complain and die if the user tries to combine `--remove-source-files` (or
1542 the deprecated `--remove-sent-files`) with `--read-batch`.
1544 - Fixed an failure transferring special files from Solaris to Linux.
1546 ------------------------------------------------------------------------------
1548 # NEWS for rsync 3.0.5 (28 Dec 2008)
1550 ## Changes in this version:
1554 - Initialize xattr data in a couple spots in the hlink code, which avoids a
1555 crash when the xattr pointer's memory happens to start out non-zero. Also
1556 fixed the itemizing of an alt-dest file's xattrs when hard-linking.
1558 - Don't send a bogus `-` option to an older server if there were no short
1561 - Fixed skipping of unneeded updates in a batch file when incremental
1562 recursion is active. Added a test for this. Made batch-mode handle `redo`
1563 files properly (and without hanging).
1565 - Fix the %P logfile escape when the daemon logs from inside a chroot.
1567 - Fixed the use of `-s` (`--protect-args`) when used with a remote source or
1568 destination that had an empty path (e.g. `host:`). Also fixed a problem when
1569 `-s` was used when accessing a daemon via a remote-shell.
1571 - Fixed the use of a dot-dir path (e.g. foo/./bar) inside a `--files-from`
1572 file when the root of the transfer isn't the current directory.
1574 - Fixed a bug with `-K --delete` removing symlinks to directories when
1575 incremental recursion is active.
1577 - Fixed a hard to trigger hang when using `--remove-source-files`.
1579 - Got rid of an annoying delay when accessing a daemon via a remote-shell.
1581 - Properly ignore (superfluous) source args on a `--read-batch` command.
1583 - Improved the manpage's description of the `*` wildcard to remove the
1584 confusing `non-empty` qualifier.
1586 - Fixed reverse lookups in the compatibility-library version of getnameinfo().
1588 - Fixed a bug when using `--sparse` on a sparse file that has over 2GB of
1589 consecutive sparse data.
1591 - Avoid a hang when using at least 3 `--verbose` options on a transfer with a
1592 client sender (which includes local copying).
1594 - Fixed a problem with `--delete-delay` reporting an error when it was ready
1595 to remove a directory that was now gone.
1597 - Got rid of a bunch of `warn_unused_result` compiler warnings.
1599 - If an ftruncate() on a received file fails, it now causes a partial-
1602 - Allow a path with a leading `//` to be preserved (CYGWIN only).
1606 - Made the atomic-rsync script able to perform a fully atomic update of the
1607 copied hierarchy when the destination is setup using a particular symlink
1608 idiom. (See the support dir.)
1610 ------------------------------------------------------------------------------
1612 # NEWS for rsync 3.0.4 (6 Sep 2008)
1614 ## Changes in this version:
1618 - Fixed a bug in the hard-linking code where it would sometimes try to
1619 allocate 0 bytes of memory (which fails on some OSes, such as AIX).
1621 - Fixed the hard-linking of files from a device that has a device number of 0
1622 (which seems to be a common device number on NetBSD).
1624 - Fixed the handling of a `--partial-dir` that cannot be created. This
1625 particularly impacts the `--delay-updates` option (since the files cannot be
1626 delayed without a partial-dir), and was potentially destructive if the
1627 `--remove-source-files` was also specified.
1629 - Fixed a couple issues in the `--fake-super` handling of xattrs when the
1630 destination files have root-level attributes (e.g. selinux values) that a
1631 non-root copy can't affect.
1633 - Improved the keep-alive check in the generator to fire consistently in
1634 incremental-recursion mode when `--timeout` is enabled.
1636 - The `--iconv` option now converts the content of a symlink too, instead of
1637 leaving it in the wrong character-set (requires 3.0.4 on both sides of the
1640 - When using `--iconv`, if a filename fails to convert on the receiving side,
1641 this no longer makes deletions in the root-dir of the transfer fail silently
1642 (the user now gets a warning about deletions being disabled due to IO error
1643 as long as `--ignore-errors` was not specified).
1645 - When using `--iconv`, if a server-side receiver can't convert a filename,
1646 the error message sent back to the client no longer mangles the name with
1647 the wrong charset conversion.
1649 - Fixed a potential alignment issue in the IRIX ACL code when allocating the
1650 initial `struct acl` object. Also, cast mallocs to avoid warnings.
1652 - Changed some errors that were going to stdout to go to stderr.
1654 - Made `human_num()` and `human_dnum()` able to output a negative number
1655 (rather than outputting a cryptic string of punctuation).
1659 - Rsync will avoid sending an `-e` option to the server if an older protocol
1660 is requested (and thus the option would not be useful). This lets the user
1661 specify the `--protocol=29` option to access an overly-restrictive server
1662 that is rejecting the protocol-30 use of `-e` to the server.
1664 - Improved the message output for an `RERR_PARTIAL` exit.
1666 ### DEVELOPER RELATED:
1668 - The Makefile will not halt for just a timestamp change on the Makefile or
1669 the configure files, only for actual changes in content.
1671 - Changed some commands in the testsuite's xattrs.test that called `rsync`
1672 instead of `$RSYNC`.
1674 - Enhanced the release scripts to be able to handle a branch release and to do
1675 even more consistency checks on the files.
1677 ------------------------------------------------------------------------------
1679 # NEWS for rsync 3.0.3 (29 Jun 2008)
1681 ## Changes in this version:
1685 - Fixed a wildcard matching problem in the daemon when a module has `use
1688 - Fixed a crash bug in the hard-link code.
1690 - Fixed the sending of xattr directory information when the code finds a
1691 `--link-dest` or `--copy-dest` directory with unchanged xattrs -- the
1692 destination directory now gets these unchanged xattrs properly applied.
1694 - Fixed an xattr-sending glitch that could cause an `Internal abbrev` error.
1696 - Fixed the combination of `--xattrs` and `--backup`.
1698 - The generator no longer allows a '.' dir to be excluded by a daemon-exclude
1701 - Fixed deletion handling when copying a single, empty directory (with no
1702 files) to a differently named, non-existent directory.
1704 - Fixed the conversion of spaces into dashes in the %M log escape.
1706 - Fixed several places in the code that were not returning the right errno
1707 when a function failed.
1709 - Fixed the backing up of a device or special file into a backup dir.
1711 - Moved the setting of the socket options prior to the connect().
1713 - If rsync exits in the middle of a `--progress` output, it now outputs a
1714 newline to help prevent the progress line from being overwritten.
1716 - Fixed a problem with how a destination path with a trailing slash or a
1717 trailing dot-dir was compared against the daemon excludes.
1719 - Fixed the sending of large (size > 16GB) files when talking to an older
1720 rsync (protocols < 30): we now use a compatible block size limit.
1722 - If a file's length is so huge that we overflow a checksum buffer count (i.e.
1723 several hundred TB), warn the user and avoid sending an invalid checksum
1724 struct over the wire.
1726 - If a source arg is excluded, `--relative` no longer adds the excluded arg's
1727 implied dirs to the transfer. This fix also made the exclude check happen in
1728 the better place in the sending code.
1730 - Use the `overflow_exit()` function for overflows, not `out_of_memory()`.
1732 - Improved the code to better handle a system that has only 32-bit file
1737 - The rsyncd.conf manpage now consistently refers to the parameters in the
1738 daemon config file as `parameters`.
1740 - The description of the `--inplace` option was improved.
1744 - Added a new script in the support directory, deny-rsync, which allows an
1745 admin to (temporarily) replace the rsync command with a script that sends an
1746 error message to the remote client via the rsync protocol.
1748 ### DEVELOPER RELATED:
1750 - Fixed a testcase failure if the tests are run as root and made some
1751 compatibility improvements.
1753 - Improved the daemon tests, including checking module comments, the listing
1754 of files, and the ensuring that daemon excludes can't affect a dot-dir arg.
1756 - Improved some build rules for those that build in a separate directory from
1757 the source, including better install rules for the manpages, and the fixing
1758 of a proto.h-tstamp rule that could make the binaries get rebuild without
1761 - Improved the testsuite to work around a problem with some utilities (e.g.
1762 `cp -p` & `touch -r`) rounding sub-second timestamps.
1764 - Ensure that the early patches don't cause any generated-file hunks to
1765 bleed-over into patches that follow.

1790 # NEWS for rsync 3.0.1 (3 Apr 2008)
1792 ## Changes in this version:
1794 ### NOTABLE CHANGES IN BEHAVIOR:
1796 - Added the 'c'-flag to the itemizing of non-regular files so that the
1797 itemized output doesn't get hidden if there were no attribute changes, and
1798 also so that the itemizing of a `--copy-links` run will distinguish between
1799 copying an identical non-regular file and the creation of a revised version
1800 with a new value (e.g. a changed symlink referent, a new device number,
1805 - Fixed a crash bug when a single-use rsync daemon (via remote shell) was run
1806 without specifying a `--config=FILE` option.
1808 - Fixed a crash when backing up a directory that has a default ACL.
1810 - Fixed a bug in the handling of xattr values that could cause rsync to not
1811 think that a file's extended attributes are up-to-date.
1813 - Fixed the working of `--fake-super` with `--link-dest` and `--xattrs`.
1815 - Fixed a hang when combining `--dry-run` with `--remove-source-files`.
1817 - Fixed a bug with `--iconv`'s handling of files that cannot be converted: a
1818 failed name can no longer cause a transfer failure.
1820 - Fixed the building of the rounding.h file on systems that need custom
1821 CPPFLAGS to be used. Also improved the error reporting if the building of
1824 - Fixed the use of the `--protect-args` (`-s`) option when talking to a
1827 - Fixed the `--ignore-existing` option's protection of files on the receiver
1828 that are non-regular files on the sender (e.g. if a symlink or a dir on the
1829 sender is trying to replace a file on the receiver). The reverse protection
1830 (protecting a dir/symlink/device from being replaced by a file) was already
1833 - Fixed an assert failure if `--hard-links` is combined with an option that
1834 can skip a file in a set of hard-linked files (i.e. `--ignore-existing`,
1835 `--append`, etc.), without skipping all the files in the set.
1837 - Avoid setting the modify time on a directory that already has the right
1838 modify time set. This avoids tweaking the dir's ctime.
1840 - Improved the daemon-exclude handling to do a better job of applying the
1841 exclude rules to path entries. It also sends the user an error just as if
1842 the files were actually missing (instead of silently ignoring the user's
1843 args), and avoids sending the user the filter-action messages for these
1844 non-user-initiated rules.
1846 - Fixed some glitches with the dry-run code's missing-directory handling,
1847 including a problem when combined with `--fuzzy`.
1849 - Fixed some glitches with the skipped-directory handling.
1851 - Fixed the 'T'-flag itemizing of symlinks when `--time` isn't preserved.
1853 - Fixed a glitch in the itemizing of permissions with the `-E` option.
1855 - The `--append` option's restricting of transfers to those that add data no
1856 longer prevents the updating of non-content changes to otherwise up-to-date
1857 files (i.e. those with the same content but differing permissions,
1858 ownership, xattrs, etc.).
1860 - Don't allow `--fake-super` to be specified with `-XX` (double `--xattrs`)
1861 because the options conflict. If a daemon has `fake super` enabled, it
1862 automatically downgrades a `-XX` request to `-X`.
1864 - Fixed a couple bugs in the parsing of daemon-config excludes that could make
1865 a floating exclude rule get treated as matching an absolute path.
1867 - A daemon doesn't try to auto-refuse the `iconv` option if iconv-support
1868 wasn't compiled in to the daemon (avoiding a warning in the logs).
1870 - Fixed the inclusion of per-dir merge files from implied dirs.
1872 - Fixed the rrsync script to work with the latest options that rsync sends,
1873 including its flag-specifying use of `-e` to the server. (See the support
1878 - Added the `--old-dirs` (`--old-d`) option to make it easier for a user to
1879 ask for file-listings with older rsync versions (this is easier than having
1880 to type `-r --exclude='/*/*'` manually).
1882 - When getting an error while asking an older rsync daemon for a file listing,
1883 rsync will try to notice if the error is a rejection of the `--dirs` (`-d`)
1884 option and let the user know how to work around the issue.
1886 - Added a few more `--no-OPTION` overrides.
1888 - Improved the documentation of the `--append` option.
1890 - Improved the documentation of the filter/exclude/include daemon parameters.
1894 - Fixed a couple minor bugs in the included popt library (ones which I sent to
1895 the official popt project for inclusion in the 1.14 release).
1897 - Fixed a stat() call that should have been `do_stat()` so that the proper
1898 normal/64-bit stat() function gets called. (Was in an area that should not
1899 have caused problems, though.)
1901 - Changed the file-glob code to do a directory scan without using the `glob`
1902 and `glob.h`. This lets us do the globbing with less memory churn, and also
1903 avoid adding daemon-excluded items to the returned args.
1905 ### DEVELOPER RELATED:
1907 - The configure script tries to get the user's compiler to not warn about
1908 unused function parameters if the build is not including one or more of the
1909 ACL/xattrs/iconv features.
1911 - The configure script now has better checks for figuring out if the included
1912 popt code should be used or not.
1914 - Fixed two testsuite glitches: avoid a failure if someone's `cd` command
1915 outputs the current directory when cd-ing to a relative path, and made the
1916 itemized test query how rsync was built to determine if it should expect
1917 hard-linked symlinks or not.
1919 - Updated the testsuite to verify that various bug fixes remain fixed.
1921 - The RPM spec file was updated to have: (1) comments for how to use the
1922 rsync-patch tar file, and (2) an /etc/xinetd.d/rsync file.
1924 - Updated the build scripts to work with a revised FTP directory structure.

1928 # NEWS for rsync 3.0.0 (1 Mar 2008)
1930 ## Changes in this version:
1932 ### PROTOCOL NUMBER:
1934 - The protocol number was changed to 30.
1936 ### NOTABLE CHANGES IN BEHAVIOR:
1938 - The handling of implied directories when using `--relative` has changed to
1939 send them as directories (e.g. no implied dir is ever sent as a symlink).
1940 This avoids unexpected behavior and should not adversely affect most people.
1941 If you're one of those rare individuals who relied upon having an implied
1942 dir be duplicated as a symlink, you should specify the transfer of the
1943 symlink and the transfer of the referent directory as separate args. (See
1944 also `--keep-dirlinks` and `--no-implied-dirs`.) Also, exclude rules no
1945 longer have a partial effect on implied dirs.
1947 - Requesting a remote file-listing without specifying `-r` (`--recursive`) now
1948 sends the `-d` (`--dirs`) option to the remote rsync rather than sending
1949 `-r` along with an extra exclude of `/*/*`. If the remote rsync does not
1950 understand the `-d` option (i.e. it is 2.6.3 or older), you will need to
1951 either turn off `-d` (`--no-d`), or specify `-r --exclude='/*/*'` manually.
1953 - In `--dry-run` mode, the last line of the verbose summary text is output
1954 with a "(DRY RUN)" suffix to help remind you that no updates were made.
1955 Similarly, `--only-write-batch` outputs `(BATCH ONLY)`.
1957 - A writable rsync daemon with `use chroot` disabled now defaults to a
1958 symlink-munging behavior designed to make symlinks safer while also allowing
1959 absolute symlinks to be stored and retrieved. This also has the effect of
1960 making symlinks unusable while they're in the daemon's hierarchy. See the
1961 daemon's `munge symlinks` parameter for details.
1963 - Starting up an extra copy of an rsync daemon will not clobber the pidfile
1964 for the running daemon -- if the pidfile exists, the new daemon will exit
1965 with an error. This means that your wrapper script that starts the rsync
1966 daemon should be made to handle lock-breaking (if you want any automatic
1967 breaking of locks to be done).
1971 - A daemon with `use chroot = no` and excluded items listed in the daemon
1972 config file now properly checks an absolute-path arg specified for these
1973 options: `--compare-dest`, `--link-dest`, `--copy-dest`, `--partial-dir`,
1974 `--backup-dir`, `--temp-dir`, and `--files-from`.
1976 - A daemon can now be told to disable all user- and group-name translation on
1977 a per-module basis. This avoids a potential problem with a writable daemon
1978 module that has `use chroot` enabled -- if precautions weren't taken, a user
1979 could try to add a missing library and get rsync to use it. This makes rsync
1980 safer by default, and more configurable when id-translation is not desired.
1981 See the daemon's `numeric ids` parameter for full details.
1983 - A chroot daemon can now indicate which part of its path should affect the
1984 chroot call, and which part should become an inside-chroot path for the
1985 module. This allows you to have outside-the-transfer paths (such as for
1986 libraries) even when you enable chroot protection. The idiom used in the
1987 rsyncd.conf file is: `path = /chroot/dirs/./dirs/inside`
1989 - If a file's data arrived successfully on the receiving side but the rename
1990 of the temporary file to the destination file failed AND the
1991 `--remove-source-files` (or the deprecated `--remove-sent-files`) option was
1992 specified, rsync no longer erroneously removes the associated source file.
1994 - Fixed the output of `-ii` when combined with one of the `--*-dest` options:
1995 it now itemizes all the items, not just the changed ones.
1997 - Made the output of all file types consistent when using a `--*-dest` option.
1998 Prior versions would output too many creation events for matching items.
2000 - The code that waits for a child pid now handles being interrupted by a
2001 signal. This fixes a problem with the pre-xfer exec function not being able
2002 to get the exit status from the script.
2004 - A negated filter rule (i.e. with a '!' modifier) no longer loses the
2005 negation when sending the filter rules to the remote rsync.
2007 - Fixed a problem with the `--out-format` (aka `--log-format`) option %f: it
2008 no longer outputs superfluous directory info for a non-daemon rsync.
2010 - Fixed a problem with `-vv` (double `--verbose`) and `--stats` when `pushing`
2011 files (which includes local copies). Version 2.6.9 would complete the copy,
2012 but exit with an error when the receiver output its memory stats.
2014 - If `--password-file` is used on a non-daemon transfer, rsync now complains
2015 and exits. This should help users figure out that they can't use this option
2016 to control a remote shell's password prompt.
2018 - Make sure that directory permissions of a newly-created destination
2019 directory are handled right when `--perms` is left off.
2021 - The itemized output of a newly-created destination directory is now output
2022 as a creation event, not a change event.
2024 - Improved `--hard-link` so that more corner cases are handled correctly when
2025 combined with options such as `--link-dest` and/or `--ignore-existing`.
2027 - The `--append` option no longer updates a file that has the same size.
2029 - Fixed a bug when combining `--backup` and `--backup-dir` with `--inplace`:
2030 any missing backup directories are now created.
2032 - Fixed a bug when using `--backup` and `--inplace` with `--whole-file` or
2033 `--read-batch`: backup files are actually created now.
2035 - The daemon pidfile is checked and created sooner in the startup sequence.
2037 - If a daemon module's `path` value is not an absolute pathname, the code now
2038 makes it absolute internally (making it work properly).
2040 - Ensure that a temporary file always has owner-write permission while we are
2041 writing to it. This avoids problems with some network filesystems when
2042 transferring read-only files.
2044 - Any errors output about password-file reading no longer cause an error at
2045 the end of the run about a partial transfer.
2047 - The `--read-batch` option for protocol 30 now ensures that several more
2048 options are set correctly for the current batch file: `--iconv`, `--acls`,
2049 `--xattrs`, `--inplace`, `--append`, and `--append-verify`.
2051 - Using `--only-write-batch` to a daemon receiver now works properly (older
2052 versions would update some files while writing the batch).
2054 - Avoid outputting a "file has vanished" message when the file is a broken
2055 symlink and `--copy-unsafe-links` or `--copy-dirlinks` is used (the code
2056 already handled this for `--copy-links`).
2058 - Fixed the combination of `--only-write-batch` and `--dry-run`.
2060 - Fixed rsync's ability to remove files that are not writable by the file's
2061 owner when rsync is running as the same user.
2063 - When transferring large files, the sender's hashtable of checksums is kept
2064 at a more reasonable state of fullness (no more than 80% full) so that the
2065 scanning of the hashtable will not bog down as the number of blocks
2070 - A new incremental-recursion algorithm is now used when rsync is talking to
2071 another 3.x version. This starts the transfer going more quickly (before all
2072 the files have been found), and requires much less memory. See the
2073 `--recursive` option in the manpage for some restrictions.
2075 - Lowered memory use in the non-incremental-recursion algorithm for typical
2076 option values (usually saving from 21-29 bytes per file).
2078 - The default `--delete` algorithm is now `--delete-during` when talking to a
2079 3.x rsync. This is a faster scan than using `--delete-before` (which is the
2080 default when talking to older rsync versions), and is compatible with the
2081 new incremental recursion mode.
2083 - Rsync now allows multiple remote-source args to be specified rather than
2084 having to rely on a special space-splitting side-effect of the remote-
2085 shell. Additional remote args must specify the same host or an empty one
2086 (e.g. empty: `:file1` or `::module/file2`). For example, this means that
2087 local use of brace expansion now works: `rsync -av host:dir/{f1,f2} .`
2089 - Added the `--protect-args` (`-s`) option, that tells rsync to send most of
2090 the command-line args at the start of the transfer rather than as args to
2091 the remote-shell command. This protects them from space-splitting, and only
2092 interprets basic wildcard special shell characters (`*?[`).
2094 - Added the `--delete-delay` option, which is a more efficient way to delete
2095 files at the end of the transfer without needing a separate delete pass.
2097 - Added the `--acls` (`-A`) option to preserve Access Control Lists. This is
2098 an improved version of the prior patch that was available, and it even
2099 supports OS X ACLs. If you need to have backward compatibility with old,
2100 ACL-patched versions of rsync, apply the acls.diff file from the patches
2103 - Added the `--xattrs` (`-X`) option to preserve extended attributes. This is
2104 an improved version of the prior patch that was available, and it even
2105 supports OS X xattrs (which includes their resource fork data). If you need
2106 to have backward compatibility with old, xattr-patched versions of rsync,
2107 apply the xattrs.diff file from the patches dir.
2109 - Added the `--fake-super` option that allows a non-super user to preserve all
2110 attributes of a file by using a special extended-attribute idiom. It even
2111 supports the storing of foreign ACL data on your backup server. There is
2112 also an analogous `fake super` parameter for an rsync daemon.
2114 - Added the `--iconv` option, which allows rsync to convert filenames from one
2115 character-set to another during the transfer. The default is to make this
2116 feature available as long as your system has `iconv_open()`. If compilation
2117 fails, specify `--disable-iconv` to configure, and then rebuild. If you want
2118 rsync to perform character-set conversions by default, you can specify
2119 `--enable-iconv=CONVERT_STRING` with the default value for the `--iconv`
2120 option that you wish to use. For example, `--enable-iconv=.` is a good
2121 choice. See the rsync manpage for an explanation of the `--iconv` option's
2124 - A new daemon config parameter, `charset`, lets you control the character-
2125 set that is used during an `--iconv` transfer to/from a daemon module. You
2126 can also set your daemon to refuse `no-iconv` if you want to force the
2127 client to use an `--iconv` transfer (requiring an rsync 3.x client).
2129 - Added the `--skip-compress=LIST` option to override the default list of file
2130 suffixes that will not be compressed when using `--compress` (`-z`).
2132 - The daemon's default for `dont compress` was extended to include: `*.7z`
2133 `*.mp[34]` `*.mov` `*.avi` `*.ogg` `*.jpg` `*.jpeg` and the name-matching routine was also
2134 optimized to run more quickly.
2136 - The `--max-delete` option now outputs a warning if it skipped any file
2137 deletions, including a count of how many deletions were skipped. (Older
2138 versions just silently stopped deleting things.)
2140 - You may specify `--max-delete=0` to a 3.0.0 client to request that it warn
2141 about extraneous files without deleting anything. If you're not sure what
2142 version the client is, you can use the less-obvious `--max-delete=-1`, as
2143 both old and new versions will treat that as the same request (though older
2144 versions don't warn).
2146 - The `--hard-link` option now uses less memory on both the sending and
2147 receiving side for all protocol versions. For protocol 30, the use of a
2148 hashtable on the sending side allows us to more efficiently convey to the
2149 receiver what files are linked together. This reduces the amount of data
2150 sent over the socket by a considerable margin (rather than adding more
2151 data), and limits the in-memory storage of the device+inode information to
2152 just the sending side for the new protocol 30, or to the receiving side when
2153 speaking an older protocol (note that older rsync versions kept the
2154 device+inode information on both sides).
2156 - The filter rules now support a perishable (`p`) modifier that marks rules
2157 that should not have an effect in a directory that is being deleted. e.g.
2158 `-f '-p .svn/'` would only affect `live` .svn directories.
2160 - Rsync checks all the alternate-destination args for validity (e.g.
2161 `--link-dest`). This lets the user know when they specified a directory that
2164 - If we get an ENOSYS error setting the time on a symlink, we don't complain
2165 about it anymore (for those systems that even support the setting of the
2166 modify-time on a symlink).
2168 - Protocol 30 now uses MD5 checksums instead of MD4.
2170 - Changed the `--append` option to not checksum the existing data in the
2171 destination file, which speeds up file appending.
2173 - Added the `--append-verify` option, which works like the older `--append`
2174 option (verifying the existing data in the destination file). For
2175 compatibility with older rsync versions, any use of `--append` that is
2176 talking protocol 29 or older will revert to the `--append-verify` method.
2178 - Added the `--contimeout=SECONDS` option that lets the user specify a
2179 connection timeout for rsync daemon access.
2181 - Documented and extended the support for the `RSYNC_CONNECT_PROG` variable
2182 that can be used to enhance the client side of a daemon connection.
2184 - Improved the dashes and double-quotes in the nroff manpage output.
2186 - Rsync now supports a lot more `--no-OPTION` override options.
2190 - The file-list sorting algorithm now uses a sort that keeps any same-named
2191 items in the same order as they were specified. This allows rsync to always
2192 ensure that the first of the duplicates is the one that will be included in
2193 the copy. The new sort is also faster than the glibc version of qsort() and
2196 - Rsync now supports the transfer of 64-bit timestamps (`time_t` values).
2198 - Made the file-deletion code use a little less stack when recursing through a
2199 directory hierarchy of extraneous files.
2201 - Fixed a build problem with older (2.x) versions of gcc.
2203 - Added some isType() functions that make dealing with signed characters
2204 easier without forcing variables via casts.
2206 - Changed strcat/strcpy/sprintf function calls to use safer versions.
2208 - Upgraded the included popt version to 1.10.2 and improved its use of
2209 string-handling functions.
2211 - Added missing prototypes for compatibility functions from the lib dir.
2213 - Configure determines if iconv() has a const arg, allowing us to avoid a
2216 - Made the sending of some numbers more efficient for protocol 30.
2218 - Make sure that a daemon process doesn't mind if the client was weird and
2219 omitted the `--server` option.
2221 - There are more internal logging categories available in protocol 30 than the
2222 age-old FINFO and FERROR, including `FERROR_XFER` and FWARN. These new
2223 categories allow some errors and warnings to go to stderr without causing an
2224 erroneous end-of-run warning about some files not being able to be
2227 - Improved the use of `const` on pointers.
2229 - Improved J.W.'s `pool_alloc` routines to add a way of incrementally freeing
2230 older sections of a pool's memory.
2232 - The getaddrinfo.c compatibility code in the `lib` dir was replaced with some
2233 new code (derived from samba, derived from PostgreSQL) that has a better
2234 license than the old code.
2236 ### DEVELOPER RELATED:
2238 - Rsync is now licensed under the GPLv3 or later.
2240 - Rsync is now being maintained in a `git` repository instead of CVS (though
2241 the old CVS repository still exists for historical access). Several
2242 maintenance scripts were updated to work with git.
2244 - Generated files are no longer committed into the source repository. The
2245 autoconf and autoheader commands are now automatically run during the normal
2246 use of `configure` and `make`. The latest dev versions of all generated
2247 files can also be copied from the samba.org web site (see the prepare-source
2248 script's fetch option).
2250 - The `patches` directory of diff files is now built from branches in the
2251 rsync git repository (branch patch/FOO creates file patches/FOO.diff). This
2252 directory is now distributed in a separate separate tar file named
2253 rsync-patches-VERSION.tar.gz instead of the main rsync-VERSION.tar.gz.
2255 - The proto.h file is now built using a simple perl script rather than a
2256 complex awk script, which proved to be more widely compatible.
2258 - When running the tests, we now put our per-test temp dirs into a sub-
2259 directory named testtmp (which is created, if missing). This allows someone
2260 to symlink the testtmp directory to another filesystem (which is useful if
2261 the build dir's filesystem does not support ACLs and xattrs, but another
2264 - Rsync now has a way of handling protocol-version changes during the
2265 development of a new protocol version. This causes any out-of-sync versions
2266 to speak an older protocol rather than fail in a cryptic manner. This
2267 addition makes it safer to deploy a pre-release version that may interact
2268 with the public. This new exchange of sub-version info does not interfere
2269 with the `{MIN,MAX}_PROTOCOL_VERSION` checking algorithm (which does not
2270 have enough range to allow the main protocol number to be incremented for
2271 every minor tweak in that happens during development).
2273 - The csprotocol.txt file was updated to mention the daemon protocol change in
2276 ------------------------------------------------------------------------------
2278 # NEWS for rsync 2.6.9 (6 Nov 2006)
2280 ## Changes in this version:
2284 - If rsync is interrupted via a handled signal (such as SIGINT), it will once
2285 again clean-up its temp file from the destination dir.
2287 - Fixed an overzealous sanitizing bug in the handling of the `--link-dest`,
2288 `--copy-dest`, and `--compare-dest` options to a daemon without chroot: if
2289 the copy's destination dir is deeper than the top of the module's path,
2290 these options now accept a safe number of parent-dir (../) references (since
2291 these options are relative to the destination dir). The old code incorrectly
2292 chopped off all `../` prefixes for these options, no matter how deep the
2293 destination directory was in the module's hierarchy.
2295 - Fixed a bug where a deferred info/error/log message could get sent directly
2296 to the sender instead of being handled by rwrite() in the generator. This
2297 fixes an `unexpected tag 3` fatal error, and should also fix a potential
2298 problem where a deferred info/error message from the receiver might bypass
2299 the log file and get sent only to the client process. (These problems could
2300 only affect an rsync daemon that was receiving files.)
2302 - Fixed a bug when `--inplace` was combined with a `--*-dest` option and we
2303 update a file's data using an alternate basis file. The code now notices
2304 that it needs to copy the matching data from the basis file instead of
2305 (wrongly) assuming that it was already present in the file.
2307 - Fixed a bug where using `--dry-run` with a `--*-dest` option with a path
2308 relative to a directory that does not yet exist: the affected option gets
2309 its proper path value so that the output of the dry-run is right.
2311 - Fixed a bug in the %f logfile escape when receiving files: the destination
2312 path is now included in the output (e.g. you can now tell when a user
2313 specifies a subdir inside a module).
2315 - If the receiving side fails to create a directory, it will now skip trying
2316 to update everything that is inside that directory.
2318 - If `--link-dest` is specified with `--checksum` but without `--times`, rsync
2319 will now allow a hard-link to be created to a matching link-dest file even
2320 when the file's modify-time doesn't match the server's file.
2322 - The daemon now calls more timezone-using functions prior to doing a chroot.
2323 This should help some C libraries to generate proper timestamps from inside
2324 a chrooted daemon (and to not try to access /etc/timezone over and over
2327 - Fixed a bug in the handling of an absolute `--partial-dir=ABS_PATH` option:
2328 it now deletes an alternate basis file from the partial-dir that was used to
2329 successfully update a destination file.
2331 - Fixed a bug in the handling of `--delete-excluded` when using a per-dir
2332 merge file: the merge file is now honored on the receiving side, and only
2333 its unqualified include/exclude commands are ignored (just as is done for
2334 global include/excludes).
2336 - Fixed a recent bug where `--delete` was not working when transferring from
2337 the root (/) of the filesystem with `--relative` enabled.
2339 - Fixed a recent bug where an `--exclude='*'` could affect the root (/) of the
2340 filesystem with `--relative` enabled.
2342 - When `--inplace` creates a file, it is now created with owner read/write
2343 permissions (0600) instead of no permissions at all. This avoids a problem
2344 continuing a transfer that was interrupted (since `--inplace` will not
2345 update a file that has no write permissions).
2347 - If either `--remove-source-files` or `--remove-sent-files` is enabled and we
2348 are unable to remove the source file, rsync now outputs an error.
2350 - Fixed a bug in the daemon's `incoming chmod` rule: newly-created directories
2351 no longer get the 'F' (file) rules applied to them.
2353 - Fixed an infinite loop bug when a filter rule was rejected due to being
2356 - When the server receives a `--partial-dir` option from the client, it no
2357 longer runs the client-side code that adds an assumed filter rule (since the
2358 client will be sending us the rules in the usual manner, and they may have
2359 chosen to override the auto-added rule).
2363 - Added the `--log-file=FILE` and `--log-file-format=FORMAT` options. These
2364 can be used to tell any rsync to output what it is doing to a log file.
2365 They work with a client rsync, a non-daemon server rsync (see the manpage
2366 for instructions), and also allows the overriding of rsyncd.conf settings
2367 when starting a daemon.
2369 - The `--log-format` option was renamed to be `--out-format` to avoid
2370 confusing it with affecting the log-file output. (The old option remains as
2371 an alias for the new to preserve backward compatibility.)
2373 - Made `log file` and `syslog facility` settable on a per-module basis in the
2374 daemon's config file.
2376 - Added the `--remove-source-files` option as a replacement for the (now
2377 deprecated) `--remove-sent-files` option. This new option removes all
2378 non-dirs from the source directories, even if the file was already
2379 up-to-date. This fixes a problem where interrupting an rsync that was using
2380 `--remove-sent-files` and restarting it could leave behind a file that the
2381 earlier rsync synchronized, but didn't get to remove. (The deprecated
2382 `--remove-sent-files` is still understood for now, and still behaves in the
2383 same way as before.)
2385 - Added the option `--no-motd` to suppress the message-of-the-day output from
2386 a daemon when doing a copy. (See the manpage for a caveat.)
2388 - Added a new environment variable to the pre-/post-xfer exec commands (in the
2389 daemon's config file): `RSYNC_PID`. This value will be the same in both the
2390 pre- and post-xfer commands, so it can be used as a unique ID if the
2391 pre-xfer command wants to cache some arg/request info for the post-xfer
2396 - Did a code audit using IBM's code-checker program and made several changes,
2397 including: replacing most of the strcpy() and sprintf() calls with
2398 strlcpy(), snprintf(), and memcpy(), adding a 0-value to an enum that had
2399 been intermingling a literal 0 with the defined enum values, silencing some
2400 uninitialized memory checks, marking some functions with a `noreturn`
2401 attribute, and changing an `if` that could never succeed on some platforms
2402 into a pre-processor directive that conditionally compiles the code.
2404 - Fixed a potential bug in `f_name_cmp()` when both the args are a top-level
2405 `.` dir (which doesn't happen in normal operations).
2407 - Changed `exit_cleanup()` so that it can never return instead of exit. The
2408 old code might return if it found the `exit_cleanup()` function was being
2409 called recursively. The new code is segmented so that any recursive calls
2410 move on to the next step of the exit-processing.
2412 - The macro WIFEXITED(stat) will now be defined if the OS didn't already
2415 ### DEVELOPER RELATED:
2417 - The acls.diff and xattrs.diff patches have received a bunch of work to make
2418 them much closer to being acceptable in the main distribution. The xattrs
2419 patch also has some preliminary Mac OS X and FreeBSD compatibility code that
2420 various system types to exchange extended file-attributes.
2422 - A new diff in the patches dir, fake-root.diff, allows rsync to maintain a
2423 backup hierarchy with full owner, group, and device info without actually
2424 running as root. It does this using a special extended attribute, so it
2425 depends on xattrs.diff (which depends on acls.diff).
2427 - The rsync.yo and rsyncd.conf.yo files have been updated to work better with
2428 the latest yodl 2.x releases.
2430 - Updated config.guess and config.sub to their 2006-07-02 versions.
2432 - Updated various files to include the latest FSF address and to have
2433 consistent opening comments.
2435 ------------------------------------------------------------------------------
2437 # NEWS for rsync 2.6.8 (22 Apr 2006)
2439 ## Changes in this version:
2443 - Fixed a bug in the exclude code where an anchored exclude without any
2444 wildcards fails to match an absolute source arg, but only when `--relative`
2447 - Improved the I/O code for the generator to fix a potential hang when the
2448 receiver gets an EOF on the socket but the generator's select() call never
2449 indicates that the socket is writable for it to be notified about the EOF.
2450 (This can happen when using stunnel).
2452 - Fixed a problem with the file-reading code where a failed read (such as that
2453 caused by a bad sector) would not advance the file's read-position beyond
2454 the failed read's data.
2456 - Fixed a logging bug where the `log file` directive was not being honored in
2457 a single-use daemon (one spawned by a remote-shell connection or by init).
2459 - If rsync cannot honor the `--delete` option, we output an error and exit
2460 instead of silently ignoring the option.
2462 - Fixed a bug in the `--link-dest` code that prevented special files (such as
2463 fifos) from being linked.
2465 - The ability to hard-link symlinks and special files is now determined at
2466 configure time instead of at runtime. This fixes a bug with `--link-dest`
2467 creating a hard-link to a symlink's referent on a BSD system.
2471 - In daemon mode, if rsync fails to bind to the requested port, the error(s)
2472 returned by socket() and/or bind() are now logged.
2474 - When we output a fatal error, we now output the version of rsync in the
2477 - Improved the documentation for the `--owner` and `--group` options.
2479 - The rsyncstats script in `support` has an improved line-parsing regex that
2480 is easier to read and also makes it to parse syslog-generated lines.
2482 - A new script in `support`: file-attr-restore, can be used to restore the
2483 attributes of a file-set (the permissions, ownership, and group info) taken
2484 from the cached output of a `find ARG... -ls` command.
2486 ### DEVELOPER RELATED:
2488 - Removed the unused function `write_int_named()`, the unused variable
2489 `io_read_phase`, and the rarely used variable `io_write_phase`. This also
2490 elides the confusing 'phase "unknown"' part of one error message.
2492 - Removed two unused configure checks and two related (also unused)
2493 compatibility functions.
2495 - The xattrs.diff patch received a security fix that prevents a potential
2496 buffer overflow in the `receive_xattr()` code.
2498 - The acls.diff patch has been improved quite a bit, with more to come.
2500 - A new patch was added: log-file.diff. This contains an early version of a
2501 future option, `--log-file=FILE`, that will allow any rsync to log its
2502 actions to a file (something that only a daemon supports at present).
2504 ------------------------------------------------------------------------------
2506 # NEWS for rsync 2.6.7 (11 Mar 2006)
2508 ## Changes in this version:
2512 - The letter 'D' in the itemized output was being used for both devices
2513 (character or block) as well as other special files (such as fifos and named
2514 sockets). This has changed to separate non-device special files under the
2515 'S' designation (e.g. `cS+++++++ path/fifo`). See also the `--specials`
2518 - The way rsync escapes unreadable characters has changed. First, rsync now
2519 has support for recognizing valid multi-byte character sequences in your
2520 current locale, allowing it to escape fewer characters than before for a
2521 locale such as UTF-8. Second, it now uses an escape idiom of `\#123`, which
2522 is the literal string `\#` followed by exactly 3 octal digits. Rsync no
2523 longer doubles a backslash character in a filename (e.g. it used to output
2524 `foo\\bar` when copying `foo\bar`) -- now it only escapes a backslash that
2525 is followed by a hash-sign and 3 digits (0-9) (e.g. it will output
2526 `foo\#134#789` when copying `foo\#789`). See also the `--8-bit-output`
2527 (`-8`) option, mentioned below.
2529 Script writers: the local rsync is the one that outputs escaped names, so if
2530 you need to support unescaping of filenames for older rsyncs, I'd suggest
2531 that you parse the output of `rsync --version` and only use the old
2532 unescaping rules for 2.6.5 and 2.6.6.
2536 - Fixed a really old bug that caused `--checksum` (`-c`) to checksum all the
2537 files encountered during the delete scan (ouch).
2539 - Fixed a potential hang in a remote generator: when the receiver gets a
2540 read-error on the socket, it now signals the generator about this so that
2541 the generator does not try to send any of the terminating error messages to
2542 the client (avoiding a potential hang in some setups).
2544 - Made hard-links work with symlinks and devices again.
2546 - If the sender gets an early EOF reading a source file, we propagate this
2547 error to the receiver so that it can discard the file and try requesting it
2548 again (which is the existing behavior for other kinds of read errors).
2550 - If a device-file/special-file changes permissions, rsync now updates the
2551 permissions without recreating the file.
2553 - If the user specifies a remote-host for both the source and destination, we
2554 now output a syntax error rather than trying to open the destination
2555 hostspec as a filename.
2557 - When `--inplace` creates a new destination file, rsync now creates it with
2558 permissions 0600 instead of 0000 -- this makes restarting possible when the
2559 transfer gets interrupted in the middle of sending a new file.
2561 - Reject the combination of `--inplace` and `--sparse` since the sparse-output
2562 algorithm doesn't work when overwriting existing data.
2564 - Fixed the directory name in the error that is output when `pop_dir()` fails.
2566 - Really fixed the parsing of a `!` entry in .cvsignore files this time.
2568 - If the generator gets a stat() error on a file, output it (this used to
2569 require at least `-vv` for the error to be seen).
2571 - If waitpid() fails or the child rsync didn't exit cleanly, we now handle the
2572 exit status properly and generate a better error.
2574 - Fixed some glitches in the double-verbose output when using `--copy-dest`,
2575 `--link-dest`, or `--compare-dest`. Also improved how the verbose output
2576 handles hard-links (within the transfer) that had an up-to-date alternate
2577 `dest` file, and copied files (via `--copy-dest`).
2579 - Fixed the matching of the dont-compress items (e.g. `*.gz`) against files
2580 that have a path component containing a slash.
2582 - If the code reading a filter/exclude file gets an EINTR error, rsync now
2583 clears the error flag on the file handle so it can keep on reading.
2585 - If `--relative` is active, the sending side cleans up trailing `/` or `/.`
2586 suffixes to avoid triggering a bug in older rsync versions. Also, we now
2587 reject a `..` dir if it would be sent as a relative dir.
2589 - If a non-directory is in the way of a directory and rsync is run with
2590 `--dry-run` and `--delete`, rsync no longer complains about not being able
2591 to opendir() the not-yet present directory.
2593 - When `--list-only` is used and a non-existent local destination dir was also
2594 specified as a destination, rsync no longer generates a warning about being
2595 unable to create the missing directory.
2597 - Fixed some problems with `--relative --no-implied-dirs` when the destination
2598 directory did not yet exist: we can now create a symlink or device when it
2599 is the first thing in the missing dir, and `--fuzzy` no longer complains
2600 about being unable to open the missing dir.
2602 - Fixed a bug where the `--copy-links` option would not affect implied
2603 directories without `--copy-unsafe-links` (see `--relative`).
2605 - Got rid of the need for `--force` to be used in some circumstances with
2606 `--delete-after` (making it consistent with
2607 `--delete-before`/`--delete-during`).
2609 - Rsync now ignores the SIGXFSZ signal, just in case your OS sends this when a
2610 file is too large (rsync handles the write error).
2612 - Fixed a bug in the Proxy-Authorization header's base64-encoded value: it was
2613 not properly padded with trailing '=' chars. This only affects a user that
2614 need to use a password-authenticated proxy for an outgoing daemon-rsync
2617 - If we're transferring an empty directory to a new name, rsync no longer
2618 forces `S_IWUSR` if it wasn't already set, nor does it accidentally leave it
2621 - Fixed a bug in the debug output (`-vvvvv`) that could mention the wrong
2622 checksum for the current file offset.
2624 - Rsync no longer allows a single directory to be copied over a non-directory
2629 - Added the `--append` option that makes rsync append data onto files that are
2630 longer on the source than the destination (this includes new files).
2632 - Added the `--min-size=SIZE` option to exclude small files from the transfer.
2634 - Added the `--compress-level` option to allow you to set how aggressive
2635 rsync's compression should be (this option implies `--compress`).
2637 - Enhanced the parsing of the SIZE value for `--min-size` and `--max-size` to
2638 allow easy entry of multiples of 1000 (instead of just multiples of 1024)
2639 and off-by-one values too (e.g. `--max-size=8mb-1`).
2641 - Added the `--8-bit-output` (`-8`) option, which tells rsync to avoid
2642 escaping high-bit characters that it thinks are unreadable in the current
2645 - The new option `--human-readable` (`-h`) changes the output of `--progress`,
2646 `--stats`, and the end-of-run summary to be easier to read. If repeated, the
2647 units become powers of 1024 instead of powers of 1000. (The old meaning of
2648 `-h`, as a shorthand for `--help`, still works as long as you just use it on
2649 its own, as in `rsync -h`.)
2651 - If lutimes() and/or lchmod() are around, use them to allow the preservation
2652 of attributes on symlinks.
2654 - The `--link-dest` option now affects symlinks and devices (when possible).
2656 - Added two config items to the rsyncd.conf parsing: `pre-xfer exec` and
2657 `post-xfer exec`. These allow a command to be specified on a per-module
2658 basis that will be run before and/or after a daemon-mode transfer. (See the
2659 manpage for a list of the environment variables that are set with
2660 information about the transfer.)
2662 - When using the `--relative` option, you can now insert a dot dir in the
2663 source path to indicate where the replication of the source dirs should
2664 start. For example, if you specify a source path of
2665 rsync://host/module/foo/bar/./baz/dir with `-R`, rsync will now only
2666 replicate the `baz/dir` part of the source path (note: a trailing dot dir is
2667 unaffected unless it also has a trailing slash).
2669 - Added some new `--no-FOO` options that make it easier to override unwanted
2670 implied or default options. For example, `-a --no-o` (aka `--archive
2671 --no-owner`) can be used to turn off the preservation of file ownership that
2674 - Added the `--chmod=MODE` option that allows the destination permissions to
2675 be changed from the source permissions. E.g. `--chmod=g+w,o-rwx`
2677 - Added the `incoming chmod` and `outgoing chmod` daemon options that allow a
2678 module to specify what permissions changes should be applied to all files
2679 copied to and from the daemon.
2681 - Allow the `--temp-dir` option to be specified when starting a daemon, which
2682 sets the default temporary directory for incoming files.
2684 - If `--delete` is combined with `--dirs` without `--recursive`, rsync will
2685 now delete in any directory whose content is being synchronized.
2687 - If `--backup` is combined with `--delete` without `--backup-dir` (and
2688 without `--delete-excluded`), we add a `protect` filter-rule to ensure that
2689 files with the backup suffix are not deleted.
2691 - The file-count stats that are output by `--progress` were improved to better
2692 indicate what the numbers mean. For instance, the output: `(xfer#5,
2693 to-check=8383/9999)` indicates that this was the fifth file to be
2694 transferred, and we still need to check 8383 more files out of a total of
2697 - The include/exclude code now allows a `dir/***` directive (with 3 trailing
2698 stars) to match both the dir itself as well as all the content below the dir
2699 (`dir/**` would not match the dir).
2701 - Added the `--prune-empty-dirs` (`-m`) option that makes the receiving rsync
2702 discard empty chains of directories from the file-list. This makes it easier
2703 to selectively copy files from a source hierarchy and end up with just the
2704 directories needed to hold the resulting files.
2706 - If the `--itemize-changes` (`-i`) option is repeated, rsync now includes
2707 unchanged files in the itemized output (similar to `-vv`, but without all
2708 the other verbose messages that can get in the way). Of course, the client
2709 must be version 2.6.7 for this to work, but the remote rsync only needs to
2710 be 2.6.7 if you're pushing files.
2712 - Added the `--specials` option to tell rsync to copy non-device special files
2713 (which rsync now attempts even as a normal user). The `--devices` option now
2714 requests the copying of just devices (character and block). The `-D` option
2715 still requests both (e.g. `--devices` and `--specials`), `-a` still implies
2716 `-D`, and non-root users still get a silent downgrade that omits device
2719 - Added the `--super` option to make the receiver always attempt super-user
2720 activities. This is useful for systems that allow things such as devices to
2721 be created or ownership to be set without being UID 0, and is also useful
2722 for someone who wants to ensure that errors will be output if the receiving
2723 rsync isn't being run as root.
2725 - Added the `--sockopts` option for those few who want to customize the TCP
2726 options used to contact a daemon rsync.
2728 - Added a way for the `--temp-dir` option to be combined with a partial-dir
2729 setting that lets rsync avoid non-atomic updates (for those times when
2730 `--temp-dir` is not being used because space is tight).
2732 - A new support script, files-to-excludes, will transform a list of files into
2733 a set of include/exclude directives that will copy those files.
2735 - A new option, `--executability` (`-E`) can be used to preserve just the
2736 execute bit on files, for those times when using the `--perms` option is not
2739 - The daemon now logs each connection and also each module-list request that
2742 - New log-format options: %M (modtime), %U (uid), %G (gid), and %B (permission
2743 bits, e.g. `rwxr-xrwt`).
2745 - The `--dry-run` option no longer forces the enabling of `--verbose`.
2747 - The `--remove-sent-files` option now does a better job of incrementally
2748 removing the sent files on the sending side (older versions tended to clump
2749 up all the removals at the end).
2751 - A daemon now supersedes its minimal SIGCHLD handler with the standard
2752 PID-remembering version after forking. This ensures that the generator can
2753 get the child-exit status from the receiver.
2755 - Use of the `--bwlimit` option no longer interferes with the remote rsync
2756 sending error messages about invalid/refused options.
2758 - Rsync no longer returns a usage error when used with one local source arg
2759 and no destination: this now implies the `--list-only` option, just like the
2760 comparable situation with a remote source arg.
2762 - Added the `--copy-dirlinks` option, a more limited version of
2765 - Various documentation improvements, including: a better synopsis, some
2766 improved examples, a better discussion of the presence and absence of
2767 `--perms` (including how it interacts with the new `--executability` and
2768 `--chmod` options), an extended discussion of `--temp-dir`, an improved
2769 discussion of `--partial-dir`, a better description of rsync's pattern
2770 matching characters, an improved `--no-implied-dirs` section, and the
2771 documenting of what the `--stats` option outputs.
2773 - Various new and updated diffs in the patches dir, including: acls.diff,
2774 xattrs.diff, atimes.diff, detect-renamed.diff, and slp.diff.
2778 - We now use sigaction() and sigprocmask() if possible, and fall back on
2779 signal() if not. Using sigprocmask() ensures that rsync enables all the
2780 signals that it needs, just in case it was started in a masked state.
2782 - Some buffer sizes were expanded a bit, particularly on systems where
2783 MAXPATHLEN is overly small (e.g. Cygwin).
2785 - If `io_printf()` tries to format more data than fits in the buffer, exit
2786 with an error instead of transmitting a truncated buffer.
2788 - If a `va_copy` macro is defined, lib/snprintf.c will use it when defining
2789 the `VA_COPY` macro.
2791 - Reduced the amount of stack memory needed for each level of directory
2792 recursion by nearly MAXPATHLEN bytes.
2794 - The wildmatch function was extended to allow an array of strings to be
2795 supplied as the string to match. This allows the exclude code to do less
2798 - Got rid of the `safe_fname()` function (and all the myriad calls) and
2799 replaced it with a new function in the log.c code that filters all the
2800 output going to the terminal.
2802 - Unified the `f_name()` and the `f_name_to()` functions.
2804 - Improved the hash-table code the sender uses to handle checksums to make it
2805 use slightly less memory and run just a little faster.
2807 ### DEVELOPER RELATED:
2809 - The diffs in the patches dir now require `patch -p1 <DIFF` instead of the
2810 previous `-p0`. Also, the version included in the release tar now affect
2811 generated files (e.g. configure, rsync.1, proto.h, etc.), so it is no longer
2812 necessary to run autoconf and/or yodl unless you're applying a patch that
2813 was checked out from CVS.
2815 - Several diffs in the patches dir now use the proper `--enable-FOO` configure
2816 option instead of `--with-FOO` to turn on the inclusion of the newly patched
2819 - There is a new script, `prepare-source` than can be used to update the
2820 various generated files (proto.h, configure, etc.) even before configure has
2821 created the Makefile (this is mainly useful when patching the source with a
2822 patch that doesn't affect generated files).
2824 - The testsuite now sets HOME so that it won't be affected by a file such as
2827 ------------------------------------------------------------------------------
2829 # NEWS for rsync 2.6.6 (28 Jul 2005)
2831 ## Changes in this version:
2835 - The zlib code was upgraded to version 1.2.3 in order to make it more secure.
2836 While the widely-publicized security problem in zlib 1.2.2 did not affect
2837 rsync, another security problem surfaced that affects rsync's zlib 1.1.4.
2841 - The setting of `flist->high` in `clean_flist()` was wrong for an empty list.
2842 This could cause `flist_find()` to crash in certain rare circumstances (e.g.
2843 if just the right directory setup was around when `--fuzzy` was combined
2844 with `--link-dest`).
2846 - The outputting of hard-linked files when verbosity was > 1 was not right:
2847 (1) Without `-i` it would output the name of each hard-linked file as though
2848 it had been changed; it now outputs a `is hard linked` message for the file.
2849 (2) With `-i` it would output all dots for the unchanged attributes of a
2850 hard-link; it now changes those dots to spaces, as is done for other totally
2853 - When backing up a changed symlink or device, get rid of any old backup item
2854 so that we don't get an `already exists` error.
2856 - A couple places that were comparing a local and a remote modification-time
2857 were not honoring the `--modify-window` option.
2859 - Fixed a bug where the 'p' (permissions) itemized-changes flag might get set
2860 too often (if some non-significant mode bits differed).
2862 - Fixed a really old, minor bug that could cause rsync to warn about being
2863 unable to mkdir() a path that ends in `/.` because it just created the
2864 directory (required `--relative`, `--no-implied-dirs`, a source path that
2865 ended in either a trailing slash or a trailing `/.`, and a non-existing
2866 destination dir to tickle the bug in a recent version).
2870 - Made the `max verbosity` setting in the rsyncd.conf file settable on a
2871 per-module basis (which now matches the documentation).
2873 - The rrsync script has been upgraded to verify the args of options that take
2874 args (instead of rejecting any such options). It was also changed to try to
2875 be more secure and to fix a problem in the parsing of a pull operation that
2876 has multiple source args. (See the support dir.)
2878 - Improved the documentation that explains the difference between a normal
2879 daemon transfer and a daemon-over remote-shell transfer.
2881 - Some of the diffs supplied in the patches dir were fixed and/or improved.
2885 - Made configure define `NOBODY_USER` (currently hard-wired to `nobody`) and
2886 `NOBODY_GROUP` (set to either `nobody` or `nogroup` depending on what we
2887 find in the /etc/group file).
2889 - Added a test to the test suite, itemized.test, that tests the output of `-i`
2890 (log-format w/%i) and some double-verbose messages.
2892 ------------------------------------------------------------------------------
2894 # NEWS for rsync 2.6.5 (1 Jun 2005)
2896 ## Changes in this version:
2900 - Non-printable chars in filenames are now output using backslash-escaped
2901 characters rather than '?'s. Any non-printable character is output using 3
2902 digits of octal (e.g. `\n` -> `\012`), and a backslash is now output as
2903 `\\`. Rsync also uses your locale setting, which can make it treat fewer
2904 high-bit characters as non-printable.
2906 - If rsync received an empty file-list when pulling files, it would output a
2907 `nothing to do` message and exit with a 0 (success) exit status, even if the
2908 remote rsync returned an error (it did not do this under the same conditions
2909 when pushing files). This was changed to make the pulling behavior the same
2910 as the pushing behavior: we now do the normal end-of-run outputting
2911 (depending on options) and exit with the appropriate exit status.
2915 - A crash bug was fixed when a daemon had its `path` set to `/`, did not have
2916 chroot enabled, and used some anchored excludes in the rsyncd.conf file.
2918 - Fixed a bug in the transfer of a single file when `-H` is specified (rsync
2919 would either infinite loop or perhaps crash).
2921 - Fixed a case where the generator might try (and fail) to tweak the
2922 write-permissions of a read-only directory in list-only mode (this only
2923 caused an annoying warning message).
2925 - If `--compare-dest` or `--link-dest` uses a locally-copied file as the basis
2926 for an updated version, log this better when `--verbose` or `-i` is in
2929 - Fixed the accidental disabling of `--backup` during the `--delete-after`
2932 - Restored the ability to use the `--address` option in client mode (in
2933 addition to its use in daemon mode).
2935 - Make sure that some temporary progress information from the delete
2936 processing does not get left on the screen when it is followed by a newline.
2938 - When `--existing` skips a directory with extra verbosity, refer to it as a
2939 `directory`, not a `file`.
2941 - When transferring a single file to a different-named file, any generator
2942 messages that are source-file related no longer refer to the file by the
2943 destination filename.
2945 - Fixed a bug where hard-linking a group of files might fail if the generator
2946 hasn't created a needed destination directory yet.
2948 - Fixed a bug where a hard-linked group of files that is newly-linked to a
2949 file in a `--link-dest` dir doesn't link the files from the rest of the
2952 - When deleting files with the `--one-file-system` (`-x`) option set, rsync no
2953 longer tries to remove files from inside a mount-point on the receiving
2954 side. Also, we don't complain about being unable to remove the mount-point
2957 - Fixed a compatibility problem when using `--cvs-ignore` (`-C`) and sending
2958 files to an older rsync without using `--delete`.
2960 - Make sure that a `- !` or `+ !` include/exclude pattern does not trigger the
2961 list-clearing action that is reserved for `!`.
2963 - Avoid a timeout in the generator when the sender/receiver aren't handling
2964 the generator's checksum output quickly enough.
2966 - Fixed the omission of some directories in the delete processing when
2967 `--relative` (`-R`) was combined with a source path that had a trailing
2970 - Fixed a case where rsync would erroneously delete some files and then
2971 re-transfer them when the options `--relative` (`-R`) and `--recursive`
2972 (`-r`) were both enabled (along with `--delete`) and a source path had a
2975 - Make sure that `--max-size` doesn't affect a device or a symlink.
2977 - Make sure that a system with a really small MAXPATHLEN does not cause the
2978 buffers in `readfd_unbuffered()` to be too small to receive normal messages.
2979 (This mainly affected Cygwin.)
2981 - If a source pathname ends with a filename of `..`, treat it as if `../` had
2982 been specified (so that we don't copy files to the parent dir of the
2985 - If `--delete` is combined with a file-listing rsync command (i.e. no
2986 transfer is happening), avoid outputting a warning that we couldn't delete
2989 - If `--stats` is specified with `--delete-after`, ensure that all the
2990 `deleting` messages are output before the statistics.
2992 - Improved one `if` in the deletion code that was only checking errno for
2993 ENOTEMPTY when it should have also been checking for EEXIST (for
2994 compatibility with OS variations).
2998 - Added the `--only-write-batch=FILE` option that may be used (instead of
2999 `--write-batch=FILE`) to create a batch file without doing any actual
3000 updating of the destination. This allows you to divert all the file-updating
3001 data away from a slow data link (as long as you are pushing the data to the
3002 remote server when creating the batch).
3004 - When the generator is taking a long time to fill up its output buffer (e.g.
3005 if the transferred files are few, small, or missing), it now periodically
3006 flushes the output buffer so that the sender/receiver can get started on the
3007 files sooner rather than later.
3009 - Improved the keep-alive code to handle a long silence between the sender and
3010 the receiver that can occur when the sender is receiving the checksum data
3013 - Improved the auth-errors that are logged by the daemon to include some
3014 information on why the authorization failed: wrong user, password mismatch,
3015 etc. (The client-visible message is unchanged!)
3017 - Improved the client's handling of an `@ERROR` from a daemon so that it does
3018 not complain about an unexpectedly closed socket (since we really did expect
3019 the socket to close).
3021 - If the daemon can't open the log-file specified in rsyncd.conf, fall back to
3022 using syslog and log an appropriate warning. This is better than what was
3023 typically a totally silent (and fatal) failure (since a daemon is not
3024 usually run with the `--no-detach` option that was necessary to see the
3027 - The manpages now consistently refer to an rsync daemon as a `daemon`
3028 instead of a `server` (to distinguish it from the server process in a
3029 non-daemon transfer).
3031 - Made a small change to the rrsync script (restricted rsync -- in the support
3032 dir) to make a read-only server reject all `--remove-*` options when sending
3033 files (to future-proof it against the possibility of other similar options
3034 being added at some point).
3038 - Rsync now calls `setlocale(LC_CTYPE, "")`. This enables isprint() to better
3039 discern which filename characters need to be escaped in messages (which
3040 should result in fewer escaped characters in some locales).
3042 - Improved the naming of the log-file open/reopen/close functions.
3044 - Removed some protocol-compatibility code that was only needed to help
3045 someone running a pre-release of 2.6.4.
3049 - Added configure option `--disable-locale` to disable any use of setlocale()
3052 - Fixed a bug in the `SUPPORT{,_HARD}_LINKS` #defines which prevented rsync
3053 from being built without symlink or hard-link support.
3055 - Only #define `HAVE_REMSH` if it is going to be set to 1.
3057 - Configure now disables the use of mkstemp() under HP-UX (since they refuse
3058 to fix its broken handling of large files).
3060 - Configure now explicitly checks for the lseek64() function so that the code
3061 can use `HAVE_LSEEK64` instead of inferring lseek64()'s presence based on
3062 the presence of the `off64_t` type.
3064 - Configure no longer mentions the change in the default remote-shell (from
3065 rsh to ssh) that occurred for the 2.6.0 release.
3067 - Some minor enhancements to the test scripts.
3069 - Added a few new `*.diff` files to the patches dir, including a patch that
3070 enables the optional copying of extended attributes.
3072 ------------------------------------------------------------------------------
3074 # NEWS for rsync 2.6.4 (30 March 2005)
3076 ## Changes in this version:
3078 ### PROTOCOL NUMBER:
3080 - The protocol number was changed to 29.
3084 - When rsync deletes a directory and outputs a verbose message about it, it
3085 now appends a trailing slash to the name instead of (only sometimes)
3086 outputting a preceding "directory " string.
3088 - The `--stats` output will contain file-list time-statistics if both sides
3089 are 2.6.4, or if the local side is 2.6.4 and the files are being pushed
3090 (since the stats come from the sending side). (Requires protocol 29 for a
3093 - The `%o` (operation) log-format escape now has a third value (besides `send`
3094 and `recv`): `del.` (with trailing dot to make it 4 chars). This changes
3095 the way deletions are logged in the daemon's log file.
3097 - When the `--log-format` option is combined with `--verbose`, rsync now
3098 avoids outputting the name of the file twice in most circumstances. As long
3099 as the `--log-format` item does not refer to any post-transfer items (such
3100 as %b or %c), the `--log-format` message is output prior to the transfer, so
3101 `--verbose` is now the equivalent of a `--log-format` of '%n%L' (which
3102 outputs the name and any link info). If the log output must occur after the
3103 transfer to be complete, the only time the name is also output prior to the
3104 transfer is when `--progress` was specified (so that the name will precede
3105 the progress stats, and the full `--log-format` output will come after).
3107 - Non-printable characters in filenames are replaced with a '?' to avoid
3108 corrupting the screen or generating empty lines in the output.
3112 - Restore the list-clearing behavior of `!` in a .cvsignore file (2.6.3 was
3113 only treating it as a special token in an rsync include/exclude file).
3115 - The combination of `--verbose` and `--dry-run` now mentions the full list of
3116 changes that would be output without `--dry-run`.
3118 - Avoid a mkdir warning when removing a directory in the destination that
3119 already exists in the `--backup-dir`.
3121 - An OS that has a binary mode for its files (such as Cygwin) needed
3122 `setmode(fd, O_BINARY)` called on the temp-file we opened with mkstemp().
3123 (Fix derived from Cygwin's 2.6.3 rsync package.)
3125 - Fixed a potential hang when verbosity is high, the client side is the
3126 sender, and the file-list is large.
3128 - Fixed a potential protocol-corrupting bug where the generator could merge a
3129 message from the receiver into the middle of a multiplexed packet of data if
3130 only part of that data had been written out to the socket when the message
3131 from the generator arrived.
3133 - We now check if the OS doesn't support using mknod() for creating FIFOs and
3134 sockets, and compile-in some compatibility code using mkfifo() and socket()
3137 - Fixed an off-by-one error in the handling of `--max-delete=N`. Also, if the
3138 `--max-delete` limit is exceeded during a run, we now output a warning about
3139 this at the end of the run and exit with a new error code (25).
3141 - One place in the code wasn't checking if fork() failed.
3143 - The `ignore nonreadable` daemon parameter used to erroneously affect
3144 readable symlinks that pointed to a non-existent file.
3146 - If the OS does not have lchown() and a chown() of a symlink will affect the
3147 referent of a symlink (as it should), we no longer try to set the user and
3150 - The generator now properly runs the hard-link loop and the dir-time
3151 rewriting loop after we're sure that the redo phase is complete.
3153 - When `--backup` was specified with `--partial-dir=DIR`, where DIR is a
3154 relative path, the backup code was erroneously trying to backup a file that
3155 was put into the partial-dir.
3157 - If a file gets resent in a single transfer and the `--backup` option is
3158 enabled along with `--inplace`, rsync no longer performs a duplicate backup
3159 (it used to overwrite the first backup with the failed file).
3161 - One call to `flush_write_file()` was not being checked for an error.
3163 - The `--no-relative` option was not being sent from the client to a server
3166 - If an rsync daemon specified `dont compress = ...` for a file and the client
3167 tried to specify `--compress`, the libz code was not handling a compression
3168 level of 0 properly. This could cause a transfer failure if the block-size
3169 for a file was large enough (e.g. rsync might have exited with an error for
3172 - Fixed a bug that would sometimes surface when using `--compress` and sending
3173 a file with a block-size larger than 64K (either manually specified, or
3174 computed due to the file being really large). Prior versions of rsync would
3175 sometimes fail to decompress the data properly, and thus the transferred
3176 file would fail its verification.
3178 - If a daemon can't open the specified log file (i.e. syslog is not being
3179 used), die without crashing. We also output an error about the failure on
3180 stderr (which will only be seen if `--no-detach` was specified) and exit
3181 with a new error code (6).
3183 - A local transfer no longer duplicates all its include/exclude options (since
3184 the forked process already has a copy of the exclude list, there's no need
3185 to send them a set of duplicates).
3187 - The output of the items that are being updated by the generator (dirs,
3188 symlinks, devices) is now intermingled in the proper order with the output
3189 from the items that the receiver is updating (regular files) when pulling.
3190 This misordering was particularly bad when `--progress` was specified.
3191 (Requires protocol 29.)
3193 - When `--timeout` is specified, lulls that occur in the transfer while the
3194 generator is doing work that does not generate socket traffic (looking for
3195 changed files, deleting files, doing directory-time touch-ups, etc.) will
3196 cause a new keep-alive packet to be sent that should keep the transfer going
3197 as long as the generator continues to make progress. (Requires protocol 29.)
3199 - The stat size of a device is not added to the total file size of the items
3200 in the transfer (the size might be undefined on some OSes).
3202 - Fixed a problem with refused-option messages sometimes not making it back to
3203 the client side when a remote `--files-from` was in effect and the daemon
3206 - The `--compare-dest` option was not updating a file that differed in (the
3207 preserved) attributes from the version in the compare-dest DIR.
3209 - When rsync is copying files into a write-protected directory, fixed the
3210 change-report output for the directory so that we don't report an identical
3211 directory as changed.
3215 - Rsync now supports popt's option aliases, which means that you can use
3216 /etc/popt and/or ~/.popt to create your own option aliases.
3218 - Added the `--delete-during` (`--del`) option which will delete files from
3219 the receiving side incrementally as each directory in the transfer is being
3220 processed. This makes it more efficient than the default,
3221 before-the-transfer behavior, which is now also available as
3222 `--delete-before` (and is still the default `--delete-WHEN` option that will
3223 be chosen if `--delete` or `--delete-excluded` is specified without a
3224 `--delete-WHEN` choice). All the `--del*` options infer `--delete`, so an
3225 rsync daemon that refuses `delete` will still refuse to allow any
3226 file-deleting options (including the new `--remove-sent-files` option).
3228 - All the `--delete-WHEN` options are now more memory efficient: Previously an
3229 duplicate set of file-list objects was created on the receiving side for the
3230 entire destination hierarchy. The new algorithm only creates one directory
3231 of objects at a time (for files inside the transfer).
3233 - Added the `--copy-dest` option, which works like `--link-dest` except that
3234 it locally copies identical files instead of hard-linking them.
3236 - Added support for specifying multiple `--compare-dest`, `--copy-dest`, or
3237 `--link-dest` options, but only of a single type. (Promoted from the patches
3238 dir and enhanced.) (Requires protocol 29.)
3240 - Added the `--max-size` option. (Promoted from the patches dir.)
3242 - The daemon-mode options are now separated from the normal rsync options so
3243 that they can't be mixed together. This makes it impossible to start a
3244 daemon that has improper default option values (which could cause problems
3245 when a client connects, such as hanging or crashing).
3247 - The `--bwlimit` option may now be used in combination with `--daemon` to
3248 specify both a default value for the daemon side and a value that cannot be
3249 exceeded by a user-specified `--bwlimit` option.
3251 - Added the `port` parameter to the rsyncd.conf file. (Promoted from the
3252 patches dir.) Also added `address`. The command-line options take precedence
3253 over a config-file option, as expected.
3255 - In `_exit_cleanup()`: when we are exiting with a partially-received file, we
3256 now flush any data in the write-cache before closing the partial file.
3258 - The `--inplace` support was enhanced to work with `--compare-dest`,
3259 `--link-dest`, and (the new) `--copy-dest` options. (Requires protocol 29.)
3261 - Added the `--dirs` (`-d`) option for an easier way to copy directories
3262 without recursion. Any directories that are encountered are created on the
3263 destination. Specifying a directory with a trailing slash copies its
3264 immediate contents to the destination.
3266 - The `--files-from` option now implies `--dirs` (`-d`).
3268 - Added the `--list-only` option, which is mainly a way for the client to put
3269 the server into listing mode without needing to resort to any internal
3270 option kluges (e.g. the age-old use of `-r --exclude='/*/*'` for a
3271 non-recursive listing). This option is used automatically (behind the
3272 scenes) when a modern rsync speaks to a modern daemon, but may also be
3273 specified manually if you want to force the use of the `--list-only` option
3274 over a remote-shell connection.
3276 - Added the `--omit-dir-times` (`-O`) option, which will avoid updating the
3277 modified time for directories when `--times` was specified. This option will
3278 avoid an extra pass through the file-list at the end of the transfer (to
3279 tweak all the directory times), which may provide an appreciable speedup for
3280 a really large transfer. (Promoted from the patches dir.)
3282 - Added the `--filter` (`-f`) option and its helper option, `-F`. Filter rules
3283 are an extension to the existing include/exclude handling that also supports
3284 nested filter files as well as per-directory filter files (like .cvsignore,
3285 but with full filter-rule parsing). This new option was chosen in order to
3286 ensure that all existing include/exclude processing remained 100% compatible
3287 with older versions. Protocol 29 is needed for full filter-rule support, but
3288 backward-compatible rules work with earlier protocol versions. (Promoted
3289 from the patches dir and enhanced.)
3291 - Added the `--delay-updates` option that puts all updated files into a
3292 temporary directory (by default `.~tmp~`, but settable via the
3293 `--partial-dir=DIR` option) until the end of the transfer. This makes the
3294 updates a little more atomic for a large transfer.
3296 - If rsync is put into the background, any output from `--progress` is
3299 - Documented the `max verbosity` setting for rsyncd.conf. (This setting was
3300 added a couple releases ago, but left undocumented.)
3302 - The sender and the generator now double-check the file-list index they are
3303 given, and refuse to try to do a file transfer on a non-file index (since
3304 that would indicate that something had gone very wrong).
3306 - Added the `--itemize-changes` (`-i`) option, which is a way to output a more
3307 detailed list of what files changed and in what way. The effect is the same
3308 as specifying a `--log-format` of `%i %n%L` (see both the rsync and
3309 rsyncd.conf manpages). Works with `--dry-run` too.
3311 - Added the `--fuzzy` (`-y`) option, which attempts to find a basis file for a
3312 file that is being created from scratch. The current algorithm only looks in
3313 the destination directory for the created file, but it does attempt to find
3314 a match based on size/mod-time (in case the file was renamed with no other
3315 changes) as well as based on a fuzzy name-matching algorithm. This option
3316 requires protocol 29 because it needs the new file-sorting order. (Promoted
3317 from patches dir and enhanced.) (Requires protocol 29.)
3319 - Added the `--remove-sent-files` option, which lets you move files between
3322 - The hostname in HOST:PATH or HOST::PATH may now be an IPv6 literal enclosed
3323 in '[' and ']' (e.g. `[::1]`). (We already allowed IPv6 literals in the
3324 rsync://HOST:PORT/PATH format.)
3326 - When rsync recurses to build the file list, it no longer keeps open one or
3327 more directory handles from the dir's parent dirs.
3329 - When building under windows, the default for `--daemon` is now to avoid
3330 detaching, requiring the new `--detach` option to force rsync to detach.
3332 - The `--dry-run` option can now be combined with either `--write-batch` or
3333 `--read-batch`, allowing you to run a do-nothing test command to see what
3334 would happen without `--dry-run`.
3336 - The daemon's `read only` config item now sets an internal `read_only`
3337 variable that makes extra sure that no write/delete calls on the read-only
3340 - The log-format % escapes can now have a numeric field width in between the %
3341 and the escape letter (e.g. `%-40n %08p`).
3343 - Improved the option descriptions in the `--help` text.
3347 - Added atomic-rsync to the support dir: a perl script that will transfer some
3348 files using rsync, and then move the updated files into place all at once at
3349 the end of the transfer. Only works when pulling, and uses `--link-dest` and
3350 a parallel hierarchy of files to effect its update.
3352 - Added mnt-excl to the support dir: a perl script that takes the /proc/mounts
3353 file and translates it into a set of excludes that will exclude all mount
3354 points (even mapped mounts to the same disk). The excludes are made relative
3355 to the specified source dir and properly anchored.
3357 - Added savetransfer.c to the support dir: a C program that can make a copy of
3358 all the data that flows over the wire. This lets you test for data
3359 corruption (by saving the data on both the sending side and the receiving
3360 side) and provides one way to debug a protocol error.
3362 - Added rrsync to the support dir: this is an updated version of Joe Smith's
3363 restricted rsync perl script. This helps to ensure that only certain rsync
3364 commands can be run by an ssh invocation.
3368 - Added better checking of the checksum-header values that come over the
3371 - Merged a variety of file-deleting functions into a single function so that
3372 it is easier to maintain.
3374 - Improved the type of some variables (particularly blocksize vars) for
3375 consistency and proper size.
3377 - Got rid of the uint64 type (which we didn't need).
3379 - Use a slightly more compatible set of core #include directives.
3381 - Defined int32 in a way that ensures that the build dies if we can't find a
3382 variable with at least 32 bits.
3384 ### PROTOCOL DIFFERENCES FOR VERSION 29:
3386 - A 16-bit flag-word is transmitted after every file-list index. This
3387 indicates what is changing between the sender and the receiver. The
3388 generator now transmits an index and a flag-word to indicate when dirs and
3389 symlinks have changed (instead of producing a message), which makes the
3390 outputting of the information more consistent and less prone to screen
3391 corruption (because the local receiver/sender is now outputting all the
3392 file-change info messages).
3394 - If a file is being hard-linked, the `ITEM_XNAME_FOLLOWS` bit is enabled in
3395 the flag-word and the name of the file that was linked immediately follows
3396 in vstring format (see below).
3398 - If a file is being transferred with an alternate-basis file, the
3399 `ITEM_BASIS_TYPE_FOLLOWS` bit is enabled in the flag-word and a single byte
3400 follows, indicating what type of basis file was chosen. If that indicates
3401 that a fuzzy-match was selected, the `ITEM_XNAME_FOLLOWS` bit is set in the
3402 flag-word and the name of the match in vstring format follows the basis
3403 byte. A vstring is a variable length string that has its size written prior
3404 to the string, and no terminating null. If the string is from 1-127 bytes,
3405 the length is a single byte. If it is from 128-32767 bytes, the length is
3406 written as ((len >> 8) | 0x80) followed by (len % 0x100).
3408 - The sending of exclude names is done using filter-rule syntax. This means
3409 that all names have a prefixed rule indicator, even excludes (which used to
3410 be sent as a bare pattern, when possible). The `-C` option will include the
3411 per-dir .cvsignore merge file in the list of filter rules so it is
3412 positioned correctly (unlike in some older transfer scenarios).
3414 - Rsync sorts the filename list in a different way: it sorts the subdir names
3415 after the non-subdir names for each dir's contents, and it always puts a
3416 dir's contents immediately after the dir's name in the list. (Previously an
3417 item named `foo.txt` would sort in between directory `foo/` and `foo/bar`.)
3419 - When talking to a protocol 29 rsync daemon, a list-only request is able to
3420 note this before the options are sent over the wire and the new
3421 `--list-only` option is included in the options.
3423 - When the `--stats` bytes are sent over the wire (or stored in a batch), they
3424 now include two elapsed-time values: one for how long it took to build the
3425 file-list, and one for how long it took to send it over the wire (each
3426 expressed in thousandths of a second).
3428 - When `--delete-excluded` is specified with some filter rules (AKA excludes),
3429 a client sender will now initiate a send of the rules to the receiver (older
3430 protocols used to omit the sending of excludes in this situation since there
3431 were no receiver-specific rules that survived `--delete-excluded` back
3432 then). Note that, as with all the filter-list sending, only items that are
3433 significant to the other side will actually be sent over the wire, so the
3434 filter-rule list that is sent in this scenario is often empty.
3436 - An index equal to the file-list count is sent as a keep-alive packet from
3437 the generator to the sender, which then forwards it on to the receiver. This
3438 normally invalid index is only a valid keep-alive packet if the 16-bit
3439 flag-word that follows it contains a single bit (`ITEM_IS_NEW`, which is
3440 normally an illegal flag to appear alone).
3442 - A protocol-29 batch file includes a bit for the setting of the `--dirs`
3443 option and for the setting of the `--compress` option. Also, the shell
3444 script created by `--write-batch` will use the `--filter` option instead of
3445 `--exclude-from` to capture any filter rules.
3449 - Handle an operating system that use mkdev() in place of makedev().
3451 - Improved configure to better handle cross-compiling.
3453 ------------------------------------------------------------------------------
3455 # NEWS for rsync 2.6.3 (30 Sep 2004)
3457 ## Changes in this version:
3461 - A bug in the `sanitize_path` routine (which affects a non-chrooted rsync
3462 daemon) could allow a user to craft a pathname that would get transformed
3463 into an absolute path for certain options (but not for file-transfer names).
3464 If you're running an rsync daemon with chroot disabled, **please upgrade**,
3465 ESPECIALLY if the user privs you run rsync under is anything above `nobody`.
3467 OUTPUT CHANGES (ATTN: those using a script to parse the verbose output):
3469 - Please note that the 2-line footer (output when verbose) now uses the term
3470 `sent` instead of `wrote` and `received` instead of `read`. If you are not
3471 parsing the numeric values out of this footer, a script would be better off
3472 using the empty line prior to the footer as the indicator that the verbose
3475 - The output from the `--stats` option was similarly affected to change
3476 `written` to `sent` and `read` to `received`.
3478 - Rsync ensures that a filename that contains a newline gets mentioned with
3479 each newline transformed into a question mark (which prevents a filename
3480 from causing an empty line to be output).
3482 - The `backed up ...` message that is output when at least 2 `--verbose`
3483 options are specified is now the same both with and without the
3484 `--backup-dir` option.
3488 - Fixed a crash bug that might appear when `--delete` was used and multiple
3489 source directories were specified.
3491 - Fixed a 32-bit truncation of the file length when generating the checksums.
3493 - The `--backup` code no longer attempts to create some directories over and
3494 over again (generating warnings along the way).
3496 - Fixed a bug in the reading of the secrets file (by the daemon) and the
3497 password file (by the client): the files no longer need to be terminated by
3498 a newline for their content to be read in.
3500 - If a file has a read error on the sending side or the reconstructed data
3501 doesn't match the expected checksum (perhaps due to the basis file changing
3502 during the transfer), the receiver will no longer retain the resulting file
3503 unless the `--partial` option was specified. (Note: for the read-error
3504 detection to work, neither side can be older than 2.6.3 -- older receivers
3505 will always retain the file, and older senders don't tell the receiver that
3506 the file had a read error.)
3508 - If a file gets resent in a single transfer and the `--backup` option is
3509 enabled, rsync no longer performs a duplicate backup (it used to overwrite
3510 the original file in the backup area).
3512 - Files specified in the daemon's `exclude` or `exclude from` config items are
3513 now excluded from being uploaded (assuming that the module allows uploading
3514 at all) in addition to the old download exclusion.
3516 - Got rid of a potential hang in the receiver when near the end of a phase.
3518 - When using `--backup` without a `--backup-dir`, rsync no longer preserves
3519 the modify time on directories. This avoids confusing NFS.
3521 - When `--copy-links` (`-L`) is specified, we now output a separate error for
3522 a symlink that has no referent instead of claiming that a file `vanished`.
3524 - The `--copy-links` (`-L`) option no longer has the side-effect of telling
3525 the receiving side to follow symlinks. See the `--keep-dirlinks` option
3526 (mentioned below) for a way to specify that behavior.
3528 - Error messages from the daemon server's option-parsing (such as refused
3529 options) are now successfully transferred back to the client (the server
3530 used to fail to send the message because the socket wasn't in the right
3531 state for the message to get through).
3533 - Most transfer errors that occur during a daemon transfer are now returned to
3534 the user in addition to being logged (some messages are intended to be
3535 daemon-only and are not affected by this).
3537 - Fixed a bug in the daemon authentication code when using one of the
3538 batch-processing options.
3540 - We try to work around some buggy IPv6 implementations that fail to implement
3541 `IPV6_V6ONLY`. This should fix the `address in use` error that some daemons
3542 get when running on an OS with a buggy IPv6 implementation. Also, if the new
3543 code gets this error, we might suggest that the user specify `--ipv4` or
3544 `--ipv6` (if we think it will help).
3546 - When the remote rsync dies, make a better effort to recover any error
3547 messages it may have sent before dying (the local rsync used to just die
3548 with a socket-write error).
3550 - When using `--delete` and a `--backup-dir` that contains files that are
3551 hard-linked to their destination equivalents, rsync now makes sure that
3552 removed files really get removed (avoids a really weird rename() behavior).
3554 - Avoid a bogus run-time complaint about a lack of 64-bit integers when the
3555 int64 type is defined as an `off_t` and it actually has 64-bits.
3557 - Added a configure check for open64() without mkstemp64() so that we can
3558 avoid using mkstemp() when such a combination is encountered. This bypasses
3559 a problem writing out large temp files on OSes such as AIX and HP-UX.
3561 - Fixed an age-old crash problem with `--read-batch` on a local copy (rsync
3562 was improperly assuming `--whole-file` for the local copy).
3564 - When `--dry-run` (`-n`) is used and the destination directory does not
3565 exist, rsync now produces a correct report of files that would be sent
3566 instead of dying with a chdir() error.
3568 - Fixed a bug that could cause a slow-to-connect rsync daemon to die with an
3569 error instead of waiting for the connection to finish.
3571 - Fixed an ssh interaction that could cause output to be lost when the user
3572 chose to combine the output of rsync's stdout and stderr (e.g. using the
3575 - Fixed an option-parsing bug when `--files-from` got passed to a daemon.
3579 - Added the `--partial-dir=DIR` option that lets you specify where to
3580 (temporarily) put a partially transferred file (instead of overwriting the
3581 destination file). E.g. `--partial-dir=.rsync-partial` Also added support
3582 for the `RSYNC_PARTIAL_DIR` environment variable that, when found,
3583 transforms a regular `--partial` option (such as the convenient `-P` option)
3584 into one that also specifies a directory.
3586 - Added `--keep-dirlinks` (`-K`), which allows you to symlink a directory onto
3587 another partition on the receiving side and have rsync treat it as matching
3588 a normal directory from the sender.
3590 - Added the `--inplace` option that tells rsync to write each destination file
3591 without using a temporary file. The matching of existing data in the
3592 destination file can be severely limited by this, but there are also cases
3593 where this is more efficient (such as appending data). Use only when needed
3594 (see the manpage for more details).
3596 - Added the `write only` option for the daemon's config file.
3598 - Added long-option names for `-4` and `-6` (namely `--ipv4` and `--ipv6`) and
3599 documented all these options in the manpage.
3601 - Improved the handling of the `--bwlimit` option so that it's less bursty,
3602 more accurate, and works properly over a larger range of values.
3604 - The rsync daemon-over-ssh code now looks for `SSH_CONNECTION` and
3605 `SSH2_CLIENT` in addition to `SSH_CLIENT` to figure out the IP address.
3607 - Added the `--checksum-seed=N` option for advanced users.
3609 - Batch writing/reading has a brand-new implementation that is simpler, fixes
3610 a few weird problems with the old code (such as no longer sprinkling the
3611 batch files into different dirs or even onto different systems), and is much
3612 less intrusive into the code (making it easier to maintain for the future).
3613 The new code generates just one data file instead of three, which makes it
3614 possible to read the batch on stdin via a remote shell. Also, the old
3615 requirement of forcing the same fixed checksum-seed for all batch processing
3618 - If an rsync daemon has a module set with `list = no` (which hides its
3619 presence in the list of available modules), a user that fails to
3620 authenticate gets the same `unknown module` error that they would get if the
3621 module were actually unknown (while still logging the real error to the
3622 daemon's log file). This prevents fishing for module names.
3624 - The daemon's `refuse options` config item now allows you to match option
3625 names using wildcards and/or the single-letter option names.
3627 - Each transferred file now gets its permissions and modified-time updated
3628 before the temp-file gets moved into place. Previously, the finished file
3629 would have a very brief window where its permissions disallowed all group
3632 - Added the ability to parse a literal IPv6 address in an `rsync:` URL (e.g.
3633 rsync://[2001:638:500:101::21]:873/module/dir).
3635 - The daemon's wildcard expanding code can now handle more than 1000 filenames
3636 (it's now limited by memory instead of having a hard-wired limit).
3640 - Some cleanup in the exclude code has saved some per-exclude memory and made
3641 the code easier to maintain.
3643 - Improved the argv-overflow checking for a remote command that has a lot of
3646 - Use rsyserr() in the various places that were still calling rprintf() with
3647 strerror() as an arg.
3649 - If an rsync daemon is listening on multiple sockets (to handle both IPv4 and
3650 IPv6 to a single port), we now close all the unneeded file handles after we
3651 accept a connection (we used to close just one of them).
3653 - Optimized the handling of larger block sizes (rsync used to slow to a crawl
3654 if the block size got too large).
3656 - Optimized away a loop in `hash_search()`.
3658 - Some improvements to the `sanitize_path()` and `clean_fname()` functions
3659 makes them more efficient and produce better results (while still being
3660 compatible with the file-name cleaning that gets done on both sides when
3661 sending the file-list).
3663 - Got rid of `alloc_sanitize_path()` after adding a destination-buffer arg to
3664 `sanitize_path()` made it possible to put all the former's functionality
3667 - The file-list that is output when at least 4 verbose options are specified
3668 reports the uid value on the sender even when rsync is not running as root
3669 (since we might be sending to a root receiver).
3673 - Added a `gen` target to rebuild most of the generated files, including
3674 configure, config.h.in, the manpages, and proto.h.
3676 - If `make proto` doesn't find some changes in the prototypes, the proto.h
3677 file is left untouched (its time-stamp used to always be updated).
3679 - The variable `$STRIP` (that is optionally set by the install-strip target's
3680 rule) was changed to `$INSTALL_STRIP` because some systems have `$STRIP`
3681 already set in the environment.
3683 - Fixed a build problem when `SUPPORT_HARD_LINKS` isn't defined.
3685 - When cross-compiling, the gettimeofday() function is now assumed to be a
3686 modern version that takes two-args (since we can't test it).
3688 ### DEVELOPER RELATED:
3690 - The scripts in the testsuite dir were cleaned up a bit and a few new tests
3693 - Some new diffs were added to the patches dir, and some accepted ones were
3696 ------------------------------------------------------------------------------
3698 # NEWS for rsync 2.6.2 (30 Apr 2004)
3700 ## Changes in this version:
3704 - Fixed a major bug in the sorting of the filenames when `--relative` is used
3705 for some sources (just sources such as `/` and `/*` were affected). This fix
3706 ensures that we ask for the right file-list item when requesting changes
3709 - Rsync now checks the return value of the close() function to better report
3710 disk-full problems on an NFS file system.
3712 - Restored the old daemon-server behavior of logging error messages rather
3713 than returning them to the user. (A better long-term fix will be sought in
3716 - An obscure uninitialized-variable bug was fixed in the uid/gid code. (This
3717 bug probably had no ill effects.)
3721 - Got rid of the configure check for sys/sysctl.h (it wasn't used and was
3722 causing a problem on some systems). Also improved the
3723 broken-largefile-locking test to try to avoid failure due to an NFS
3726 - Fixed a compile problem on systems that don't define `AI_NUMERICHOST`.
3728 - Fixed a compile problem in the popt source for compilers that don't support
3731 ### DEVELOPER RELATED:
3733 - Improved the testsuite's `merge` test to work on OSF1.
3735 - Two new diffs were added to the patches dir.
3737 ------------------------------------------------------------------------------
3739 # NEWS for rsync 2.6.1 (26 Apr 2004)
3741 ## Changes in this version:
3743 ### PROTOCOL NUMBER:
3745 - The protocol number was changed to 28.
3749 - Paths sent to an rsync daemon are more thoroughly sanitized when chroot is
3750 not used. If you're running a non-read-only rsync daemon with chroot
3751 disabled, **please upgrade**, ESPECIALLY if the user privs you run rsync
3752 under is anything above `nobody`.
3756 - Lower memory use, more optimal transfer of data over the socket, and lower
3757 CPU usage (see the INTERNAL section for details).
3759 - The `RSYNC_PROXY` environment variable can now contain a `USER:PASS@` prefix
3760 before the `HOST:PORT` information. (Bardur Arantsson)
3762 - The `--progress` output now mentions how far along in the transfer we are,
3763 including both a count of files transferred and a percentage of the total
3764 file-count that we've processed. It also shows better
3765 current-rate-of-transfer and remaining-transfer-time values.
3767 - Documentation changes now attempt to describe some often misunderstood
3768 features more clearly.
3772 - When `-x` (`--one-file-system`) is combined with `-L` (`--copy-links`) or
3773 `--copy-unsafe-links,` no symlinked files are skipped, even if the referent
3774 file is on a different filesystem.
3776 - The `--link-dest` code now works properly for a non-root user when (1) the
3777 UIDs of the source and destination differ and `-o` was specified, or (2)
3778 when the group of the source can't be used on the destination and `-g` was
3781 - Fixed a bug in the handling of `-H` (hard-links) that might cause the
3782 expanded PATH/NAME value of the current item to get overwritten (due to an
3783 expanded-name caching bug).
3785 - We now reset the `new data has been sent` flag at the start of each file we
3786 send. This makes sure that an interrupted transfer with the `--partial`
3787 option set doesn't keep a shorter temp file than the current basis file when
3788 no new data has been transferred over the wire for that file.
3790 - Fixed a byte-order problem in `--batch-mode` on big-endian machines. (Jay
3793 - When using `--cvs-exclude`, the exclude items we get from a per-directory's
3794 .cvsignore file once again only affect that one directory (not all following
3795 directories too). The items are also now properly word-split and parsed
3796 without any +/- prefix parsing.
3798 - When specifying the USER@HOST: prefix for a file, the USER part can now
3799 contain an '@', if needed (i.e. the last '@' is used to find the HOST, not
3802 - Fixed some bugs in the handling of group IDs for non-root users: (1) It
3803 properly handles a group that the sender didn't have a name for (it would
3804 previously skip changing the group on any files in that group). (2) If
3805 `--numeric-ids` is used, rsync no longer attempts to set groups that the
3806 user doesn't have the permission to set.
3808 - Fixed the `refuse options` setting in the rsyncd.conf file.
3810 - Improved the `-x` (`--one-file-system`) flag's handling of any mount-point
3811 directories we encounter. It is both more optimal (in that it no longer does
3812 a useless scan of the contents of the mount-point dirs) and also fixes a
3813 bug where a remapped mount of the original filesystem could get discovered
3814 in a subdir we should be ignoring.
3816 - Rsync no longer discards a double-slash at the start of a filename when
3817 trying to open the file. It also no longer constructs names that start with
3818 a double slash (unless the user supplied them).
3820 - Path-specifying options to a daemon should now work the same with or without
3821 chroot turned on. Previously, such a option (such as `--link-dest`) would
3822 get its absolute path munged into a relative one if chroot was not on,
3823 making that setting fairly useless. Rsync now transforms the path into one
3824 that is based on the module's base dir when chroot is not enabled.
3826 - Fixed a compatibility problem interacting with older rsync versions that
3827 might send us an empty `--suffix` value without telling us that
3828 `--backup-dir` was specified.
3830 - The `hosts allow` option for a daemon-over-remote-shell process now has
3831 improved support for IPv6 addresses and a fix for systems that have a length
3832 field in their socket structs.
3834 - Fixed the ability to request an empty backup `--suffix` when sending files
3837 - Fixed an option-parsing bug when `--files-from` was sent to a server sender.
3841 - Most of the I/O is now buffered, which results in a pretty large speedup
3842 when running under MS Windows. (Craig Barratt)
3844 - Optimizations to the name-handling/comparing code have made some significant
3845 reductions in user-CPU time for large file sets.
3847 - Some cleanup of the variable types make the code more consistent.
3849 - Reduced memory requirements of hard link preservation. (J.W. Schultz)
3851 - Implemented a new algorithm for hard-link handling that speeds up the code
3852 significantly. (J.W. Schultz and Wayne Davison)
3854 - The `--hard-link` option now uses the first existing file in the group of
3855 linked files as the basis for the transfer. This prevents the sub-optimal
3856 transfer of a file's data when a new hardlink is added on the sending side
3857 and it sorts alphabetically earlier in the list than the files that are
3858 already present on the receiving side.
3860 - Dropped support for protocol versions less than 20 (2.3.0 released 15 Mar
3861 1999) and activated warnings for protocols less than 25 (2.5.0 released 23
3862 Aug 2001). (Wayne Davison and J.W. Schultz, severally)
3864 - More optimal data transmission for `--hard-links` (protocol 28).
3866 - More optimal data transmission for `--checksum` (protocol 28).
3868 - Less memory is used when `--checksum` is specified.
3870 - Less memory is used in the file list (a per-file savings).
3872 - The generator is now better about not modifying the file list during the
3873 transfer in order to avoid a copy-on-write memory bifurcation (on systems
3874 where fork() uses shared memory). Previously, rsync's shared memory would
3875 slowly become unshared, resulting in real memory usage nearly doubling on
3876 the receiving side by the end of the transfer. Now, as long as permissions
3877 are being preserved, the shared memory should remain that way for the entire
3880 - Changed hardlink info and `file_struct` + strings to use allocation pools.
3881 This reduces memory use for large file-sets and permits freeing memory to
3882 the OS. (J.W. Schultz)
3884 - The 2 pipes used between the receiver and generator processes (which are
3885 forked on the same machine) were reduced to 1 pipe and the protocol improved
3886 so that (1) it is now impossible to have the `redo` pipe fill up and hang
3887 rsync, and (2) trailing messages from the receiver don't get lost on their
3888 way through the generator over to the sender (which mainly affected
3889 hard-link messages and verbose `--stats` output).
3891 - Improved the internal uid/gid code to be more portable and a little more
3894 - The device numbers sent when using `--devices` are now sent as separate
3895 major/minor values with 32-bit accuracy (protocol 28). Previously, the
3896 copied devices were sent as a single 32-bit number. This will make
3897 inter-operation of 64-bit binaries more compatible with their 32-bit
3898 brethren (with both ends of the connection are using protocol 28). Note that
3899 optimizations in the binary protocol for sending the device numbers often
3900 results in fewer bytes being used than before, even though more precision is
3903 - Some cleanup of the exclude/include structures and its code made things
3904 clearer (internally), simpler, and more efficient.
3906 - The reading & writing of the file-list in batch-mode is now handled by the
3907 same code that sends & receives the list over the wire. This makes it much
3908 easier to maintain. (Note that the batch code is still considered to be
3913 - The configure script now accepts `--with-rsyncd-conf=PATH` to override the
3914 default value of the /etc/rsyncd.conf file.
3916 - Fixed configure bug when running `./configure --disable-ipv6`.
3918 - Fixed compilation problem on Tru64 Unix (having to do with `sockaddr.sa_len`
3919 and `sockaddr.sin_len`).
3921 ### DEVELOPER RELATED:
3923 - Fixed `make test` bug when build dir is not the source dir.
3925 - Added a couple extra diffs in the `patches` dir, removed the ones that got
3926 applied, and rebuilt the rest.
3928 ------------------------------------------------------------------------------
3930 # NEWS for rsync 2.6.0 (1 Jan 2004)
3932 ## Changes in this version:
3934 ### PROTOCOL NUMBER:
3936 - The protocol number was changed to 27. The maximum accepted protocol number
3937 was increased from 30 to 40.
3941 - `ssh` is now the default remote shell for rsync. If you want to change this,
3942 configure like this: `./configure --with-rsh=rsh`.
3944 - Added `--files-from`, `--no-relative`, `--no-implied-dirs`, and `--from0`.
3945 Note that `--from0` affects the line-ending character for all the files read
3946 by the `--*-from` options. (Wayne Davison)
3948 - Length of csum2 is now per-file starting with protocol version
3951 - Per-file dynamic block size is now sqrt(file length). The per-file checksum
3952 size is determined according to an algorithm provided by Donovan Baarda
3953 which reduces the probability of rsync algorithm corrupting data and falling
3954 back using the whole md4 checksums. (J.W. Schultz, Donovan Baarda)
3956 - The `--stats` option no longer includes the (debug) malloc summary unless
3957 the verbose option was specified at least twice.
3959 - Added a new error/warning code for when files vanish from the sending side.
3960 Made vanished source files not interfere with the file-deletion pass when
3961 `--delete-after` was specified.
3963 - Various trailing-info sections are now preceded by a newline.
3967 - Fixed several exclude/include matching bugs when using wild-cards. This has
3968 a several user-visible effects, all of which make the matching more
3969 consistent and intuitive. This should hopefully not cause anyone problems
3970 since it makes the matching work more like what people are expecting. (Wayne
3973 - A pattern with a `**` no longer causes a `*` to match slashes. For example,
3974 with `/*/foo/**`, `foo` must be 2 levels deep. [If your string has BOTH `*`
3975 and `**` wildcards, changing the `*` wildcards to `**` will provide the old
3976 behavior in all versions.]
3978 - `**/foo` now matches at the base of the transfer (like /foo does). [Use
3979 `/**/foo` to get the old behavior in all versions.]
3981 - A non-anchored wildcard term floats to match beyond the base of the
3982 transfer. E.g. `CVS/R*` matches at the end of the path, just like the
3983 non-wildcard term `CVS/Root` does. [Use `/CVS/R*` to get the old behavior in
3986 - Including a `**` in the match term causes it to be matched against the
3987 entire path, not just the name portion, even if there aren't any interior
3988 slashes in the term. E.g. `foo**bar` would exclude `/path/foo-bar` (just
3989 like before) as well as `/foo-path/baz-bar` (unlike before). [Use `foo*bar`
3990 to get the old behavior in all versions.]
3992 - The exclude list specified in the daemon's config file is now properly
3993 applied to the pulled items no matter how deep the user's file-args are in
3994 the source tree. (Wayne Davison)
3996 - For protocol version >= 27, `mdfour_tail()` is called when the block size
3997 (including `checksum_seed`) is a multiple of 64. Previously it was not
3998 called, giving the wrong MD4 checksum. (Craig Barratt)
4000 - For protocol version >= 27, a 64 bit bit counter is used in mdfour.c as
4001 required by the RFC. Previously only a 32 bit bit counter was used, causing
4002 incorrect MD4 file checksums for file sizes >= 512MB - 4. (Craig Barratt)
4004 - Fixed a crash bug when interacting with older rsync versions and multiple
4005 files of the same name are destined for the same dir. (Wayne Davison)
4007 - Keep tmp names from overflowing MAXPATHLEN.
4009 - Make `--link-dest` honor the absence of `-p`, `-o`, and `-g`.
4011 - Made rsync treat a trailing slash in the destination in a more consistent
4014 - Fixed file I/O error detection. (John Van Essen)
4016 - Fixed bogus `malformed address {hostname}` message in rsyncd log when
4017 checking IP address against hostnames from `hosts allow` and `hosts deny`
4018 parameters in config file.
4020 - Print heap statistics when verbose >= 2 instead of when >= 1.
4022 - Fixed a compression (`-z`) bug when syncing a mostly-matching file that
4023 contains already-compressed data. (Yasuoka Masahiko and Wayne Davison)
4025 - Fixed a bug in the `--backup` code that could cause deleted files to not get
4028 - When the backup code makes new directories, create them with mode 0700
4029 instead of 0755 (since the directory permissions in the backup tree are not
4030 yet copied from the main tree).
4032 - Call setgroups() in a more portable manner.
4034 - Improved file-related error messages to better indicate exactly what
4035 pathname failed. (Wayne Davison)
4037 - Fixed some bugs in the handling of `--delete` and `--exclude` when using the
4038 `--relative` (`-R`) option. (Wayne Davison)
4040 - Fixed bug that prevented regular files from replacing special files and
4041 caused a directory in `--link-dest` or `--compare-dest` to block the
4042 creation of a file with the same path. A directory still cannot be replaced
4043 by a regular file unless `--delete` specified. (J.W. Schultz)
4045 - Detect and report when open or opendir succeed but read and readdir fail
4046 caused by network filesystem issues and truncated files. (David Norwood,
4047 Michael Brown, J.W. Schultz)
4049 - Added a fix that should give ssh time to restore the tty settings if the
4050 user presses Ctrl-C at an ssh password prompt.
4054 - Eliminated vestigial support for old versions that we stopped supporting.
4057 - Simplified some of the option-parsing code. (Wayne Davison)
4059 - Some cleanup made to the exclude code, as well as some new defines added to
4060 enhance readability. (Wayne Davison)
4062 - Changed the protocol-version code so that it can interact at a lower
4063 protocol level than the maximum supported by both sides. Added an
4064 undocumented option, `--protocol=N`, to force the value we advertise to the
4065 other side (primarily for testing purposes). (Wayne Davison)

4075 - Fix buffer handling bugs. (Andrew Tridgell, Martin Pool, Paul Russell,
4078 ------------------------------------------------------------------------------
4080 # NEWS for rsync 2.5.6, aka "the dwd-between-jobs release" (26 Jan 2003)
4082 ## Changes in this version:
4086 - The `--delete-after` option now implies `--delete`. (Wayne Davison)
4088 - The `--suffix` option can now be used with `--backup-dir`. (Michael
4091 - Combining `::` syntax with the `--rsh`/`-e` option now uses the specified
4092 remote-shell as a transport to talk to a (newly-spawned) server-daemon. This
4093 allows someone to use daemon features, such as modules, over a secure
4094 protocol, such as ssh. (JD Paul)
4096 - The rsync:// syntax for daemon connections is now accepted in the
4099 - If the file name given to `--include-from` or `--exclude-from` is `-`, rsync
4100 will read from standard input. (J.W. Schultz)
4102 - New option `--link-dest` which is like `--compare-dest` except that
4103 unchanged files are hard-linked in to the destination directory. (J.W.
4106 - Don't report an error if an excluded file disappears during an rsync run.
4107 (Eugene Chupriyanov and Bo Kersey)
4109 - Added .svn to `--cvs-exclude` list to support subversion. (Jon Middleton)
4111 - Properly support IPv6 addresses in the rsyncd.conf `hosts allow` and `hosts
4112 deny` fields. (Hideaki Yoshifuji)
4114 - Changed exclude file handling to permit DOS or MAC style line terminations.
4117 - Ignore errors from chmod when `-p`/`-a`/`--preserve-perms` is not set.
4122 - Fix `forward name lookup failed` errors on AIX 4.3.3. (John L. Allen, Martin
4125 - Generate each file's rolling-checksum data as we send it, not in a separate
4126 (memory-eating) pass before hand. This prevents timeout errors on really
4127 large files. (Stefan Nehlsen)
4129 - Fix compilation on Tru64. (Albert Chin, Zoong Pham)
4131 - Better handling of some client-server errors. (Martin Pool)
4133 - Fixed a crash that would occur when sending a list of files that contains a
4134 duplicate name (if it sorts to the end of the file list) and using
4135 `--delete`. (Wayne Davison)
4137 - Fixed the file-name duplicate-removal code when dealing with multiple dups
4138 in a row. (Wayne Davison)
4140 - Fixed a bug that caused rsync to lose the exit status of its child processes
4141 and sometimes return an exit code of 0 instead of showing an error. (David
4142 R. Staples, Dave Dykstra)
4144 - Fixed bug in `--copy-unsafe-links` that caused it to be completely broken.
4147 - Prevent infinite recursion in cleanup code under certain circumstances.
4148 (Sviatoslav Sviridov and Marc Espie)
4150 - Fixed a bug that prevented rsync from creating intervening directories when
4151 `--relative-paths`/`-R` is set. (Craig Barratt)
4153 - Prevent `Connection reset by peer` messages from Cygwin. (Randy O'Meara)
4157 - Many code cleanups and improved internal documentation. (Martin Pool, Nelson
4160 - Portability fixes. (Dave Dykstra and Wayne Davison)
4162 - More test cases. (Martin Pool)
4164 - Some test-case fixes. (Brian Poole, Wayne Davison)
4166 - Updated included popt to the latest vendor drop, version 1.6.4. (Jos
4169 - Updated config.guess and config.sub to latest versions; this means rsync
4170 should build on more platforms. (Paul Green)
4172 ------------------------------------------------------------------------------
4174 # NEWS for rsync 2.5.5, aka Snowy River (2 Apr 2002)
4176 ## Changes in this version:
4180 - With `--progress`, when a transfer is complete show the time taken;
4181 otherwise show expected time to complete. (Cameron Simpson)
4183 - Make `make install-strip` works properly, and `make install` accepts a
4184 DESTDIR variable for help in building binary packages. (Peter
4185 Breitenlohner, Greg Louis)
4187 - If configured with `--enable-maintainer-mode`, then on receipt of a fatal
4188 signal rsync will try to open an xterm running gdb, similarly to Samba's
4189 `panic action` or GNOME's bug-buddy. (Martin Pool)
4193 - Fix situation where failure to fork (e.g. because out of process slots)
4194 would cause rsync to kill all processes owned by the current user. Yes,
4195 really! (Paul Haas, Martin Pool)
4197 - Fix test suite on Solaris. (Jos Backus, Martin Pool)
4199 - Fix minor memory leak in socket code. (Dave Dykstra, Martin Pool.)
4201 - Fix `--whole-file` problem that caused it to be the default even for remote
4202 connections. (Martin Pool, Frank Schulz)
4204 - Work around bug in Mac OS X mkdir(2), which cannot handle trailing slashes.
4205 <http://www.opensource.apple.com/bugs/X/BSD%20Kernel/2734739.html> (Martin
4208 - Improved network error handling. (Greg A. Woods)
4210 ------------------------------------------------------------------------------
4212 # NEWS for rsync 2.5.4, aka "Imitation lizard skin" (13 Mar 2002)
4214 ## Changes in this version:
4218 - Additional fix for zlib double-free bug. (Martin Pool, Andrew Tridgell) (CVE
4223 - Merge in changes from zlib 1.1.3 to zlib 1.1.4. (Jos Backus) (Note that
4224 rsync still uses a custom version of zlib; you can not just link against a
4225 system library. See zlib/README.rsync)
4227 - Additional test cases for `--compress`. (Martin Pool)
4229 ------------------------------------------------------------------------------
4231 # NEWS for rsync 2.5.3, aka "Happy 26" (11 Mar 2002)
4233 ## Changes in this version:
4237 - Make sure that supplementary groups are removed from a server
4238 process after changing uid and gid. (Ethan Benson) (Debian bug
4239 #132272, CVE CAN-2002-0080)
4243 - Fix zlib double-free bug. (Owen Taylor, Mark J Cox) (CVE CAN-2002-0059)
4245 - Fixed problem that in many cases caused the error message unexpected read
4246 size of 0 in `map_ptr` and resulted in the wrong data being copied.
4248 - Fixed compilation errors on some systems caused by the use of `unsigned
4251 - Fixed problem on systems such as Sunos4 that do not support realloc on a
4252 NULL pointer; error was 'out of memory in "flist_expand"'.
4254 - Fix for rsync server processes hanging around after the client unexpectedly
4255 disconnects. (Colin Walters) (Debian bug #128632)
4257 - Cope with BSD systems on which mkdir() will not accept a trailing slash.
4261 - Merge in changes from zlib 1.1.2 to zlib 1.1.3. (Note that rsync still uses
4262 a custom version of zlib; you can not just link against a system library.
4263 See zlib/README.rsync)
4265 - Command to initiate connections is only shown with `-vv`, rather than `-v`
4266 as in 2.5.2. Output from plain `-v` is more similar to what was historically
4267 used so as not to break scripts that try to parse the output.
4269 - Added `--no-whole-file` and `--no-blocking-io` options (Dave Dykstra)
4271 - Made the `--write-batch` and `--read-batch` options actually work and added
4272 documentation in the manpage (Jos Backus)
4274 - If the daemon is unable to fork a child to accept a connection, print an
4275 error message. (Colin Walters)
4277 ------------------------------------------------------------------------------
4279 # NEWS for rsync 2.5.2 (26 Jan 2002)
4281 ## Changes in this version:
4285 - Signedness security patch from Sebastian Krahmer <krahmer@suse.de> -- in
4286 some cases we were not sufficiently careful about reading integers from the
4289 ### PROTOCOL NUMBER:
4291 - The protocol number was changed to 26.
4295 - Fix possible string mangling in log files.
4297 - Fix for setting local address of outgoing sockets.
4299 - Better handling of hardlinks and devices on platforms with 64-bit `dev_t` or
4302 - Name resolution on machines supporting IPv6 is improved.
4304 - Fix for device nodes. (dann frazier) (Debian #129135)
4308 - With `-v`, rsync now shows the command used to initiate an ssh/rsh
4311 - `--statistics` now shows memory heap usage on platforms that support
4314 - "The Ted T'so school of program optimization": make progress visible and
4315 people will think it's faster. (With `--progress`, rsync will show you how
4316 many files it has seen as it builds the `file_list`, giving some indication
4317 that it has not hung.)
4319 - Improvements to batch mode support. This is still experimental but testing
4320 would be welcome. (Jos Backus)
4322 - New `--ignore-existing` option, patch previously distributed with Vipul's
4323 Razor. (Debian #124286)
4325 ------------------------------------------------------------------------------
4327 # NEWS for rsync 2.5.1 (3 Jan 2002)
4329 ## Changes in this version:

4336 SUMIKAWA Munechika and Jun-ichiro `itojun` Hagino)
4338 - Various fixes for IPv6 support. (Dave Dykstra)
4340 - rsync.1 typo fix. (Matt Kraai)
4342 - Test suite typo fixes. (Tom Schmidt)
4344 - rsync.1 grammar and clarity improvements. (Edward Welbourne)
4346 - Correction to ./configure tests for `inet_ntop`. (Jeff Garzik)
4350 - `--progress` and `-P` now show estimated data transfer rate (in a multiple
4351 of bytes/s) and estimated time to completion. (Rik Faith)
4353 - `--no-detach` option, required to run as a W32 service and also useful when
4354 running on Unix under daemontools, AIX's SRC, or a debugger. (Max Bowsher,
4357 - Clearer error messages for some conditions.
4359 ------------------------------------------------------------------------------
4361 # NEWS for rsync 2.5.0 (30 Nov 2001)
4363 ## Changes in this version:
4365 ### PROTOCOL NUMBER:
4367 - The protocol number was changed to 25.
4371 - Martin Pool <mbp@samba.org> is now a co-maintainer.
4375 - Support for LSB-compliant packaging <http://www.linuxbase.org/>
4377 - Shell wildcards are allowed in `auth users` lines.
4379 - Merged UNC rsync+ patch to support creation of standalone patch sets. By
4380 Bert J. Dempsey and Debra Weiss, updated by Jos Backus.
4381 <http://www.ils.unc.edu/i2dsi/unc_rsync+.html>
4383 - IPv6 support based on a patch from KAME.net, on systems including modern
4384 versions of Linux, Solaris, and HP-UX. Also includes IPv6 compatibility
4385 functions for old OSs by the Internet Software Consortium, Paul Vixie, the
4386 OpenSSH portability project, and OpenBSD.
4390 - Include/exclude cluestick: with `-vv`, print out whether files are included
4391 or excluded and why.
4393 - Many error messages have more friendly explanations and more details.
4395 - Manual page improvements plus scanty protocol documentation.
4397 - When running as `--daemon` in the background and using a `log file`
4398 rsyncd.conf directive, close the log file every time it is open when going
4399 to sleep on the socket. This allows the log file to get cleaned out by
4402 - Change to using libpopt rather than getopt for processing options. This
4403 makes the code cleaner and the behaviour more consistent across platforms.
4404 popt is included and built if not installed on the platform.
4406 - More details in `--version`, including note about whether 64-bit files,
4407 symlinks and hardlinks are supported.
4409 - MD4 code may use less CPU cycles.
4411 - Use mkstemp on systems where it is secure. If we use mktemp, explain that we
4412 do it in a secure way.
4414 - `--whole-file` is the default when source and target are on the local
4419 - Fix for various bugs causing rsync to hang.
4421 - Attempt to fix Large File Summit support on AIX.
4423 - Attempt to fix error handling lockup bug.
4425 - Give a non-0 exit code if **any** of the files we have been asked to
4426 transfer fail to transfer.
4428 - For log messages containing ridiculously long strings that might overflow a
4429 buffer rsync no longer aborts, but rather prints an ellipsis at the end of
4430 the string. (Patch from Ed Santiago.)
4434 - Improved support for UNICOS (tested on Cray T3E and Cray SV1)
4436 - autoconf2.52 (or later) is now required to rebuild the autoconf scripts. It
4437 is not required to simply build rsync.
4439 - Platforms thought to work in this release:
