2 # NEWS for rsync 3.2.4 (UNRELEASED)
4 ## Changes in this version:
8 - A new form of arg protection was added that works similarly to the older
9 `--protect-args` (`-s`) option but in a way that avoids breaking things like
10 rrsync (the restricted rsync script): rsync now uses backslash escaping for
11 sending "shell-active" characters to the remote shell. This includes spaces,
12 so fetching a remote file via a simple quoted filename value now works by
13 default without any extra quoting:
16 rsync -aiv host:'a simple file.pdf' .
19 Wildcards are not escaped in filename args, but they are escaped in options
20 like the `--suffix` and `--usermap` values. If your rsync script depends on
21 the old arg-splitting behavior, either run it with the `--old-args` option
22 or `export RSYNC_OLD_ARGS=1` in the script's environment.
24 - A long-standing bug was preventing rsync from figuring out the current
25 locale's decimal point character, which made rsync always output numbers
26 using the "C" locale. Since this is now fixed in 3.2.4, a script that
27 parses rsync's decimal numbers (e.g. from the verbose footer) should be sure
28 to setup the environment in a way that the output continues to be in the C
29 locale. For instance, one of the following should work fine:
35 or if iconv translations are needed:
38 if [ "${LC_ALL:-}" ]; then
40 export LC_CTYPE="$LC_ALL"
43 export LC_NUMERIC=C.UTF-8
48 - Fixed a bug with `--inplace` + `--sparse` (and a lack of `--whole-file`)
49 where the destination file could get reconstructed with bogus data. Since
50 the bug can also be avoided by using (the seemingly redundant) `--no-W` on
51 the receiving side, the latest rsync will now send `--no-W` to a remote
52 receiver when this option combination occurs. If your client rsync is not
53 new enough to do this for you (or if you're just paranoid), you can manually
54 specify `--no-W -M--no-W` (when not using `--whole-file`) to make sure the
57 - Fixed a bug with `--mkpath` if a single-file copy specifies an existing
58 destination dir with a non-existing destination filename.
60 - Fixed `--update -vv` to output "is uptodate" instead of "is newer" messages
61 for files that are being skipped due to an identical modify time. (This
62 was a new output quirk in 3.2.3.)
64 - When doing an append transfer, the sending side's file must not get shorter
65 or it is skipped. Fixes a crash that could occur when the size changes to 0
66 in the middle of the send negotiations.
68 - When dealing with special files (see `--specials`) in an alt-dest hierarchy,
69 rsync now checks the non-permission mode bits to ensure that the 2 special
70 files are really the same before hard-linking them together.
72 - Fixed a bug where `--delay-updates` with stale partial data could cause a
73 file to fail to update.
75 - Fixed a few places that would output an INFO message with `--info=NAME` that
76 should only have been output given `--verbose` or `--itemize-changes`.
78 - Avoid a weird failure if you run a local copy with a (useless) `--rsh`
79 option that contains a `V` in the command.
81 - Fixed a long-standing compression bug where the compression level of the
82 first file transferred affected the level for all future files. Also, the
83 per-file compression skipping has apparently never worked, so it is now
84 documented as being ineffective.
86 - Improved how the `--stop-at`, `--stop-after`, and `--time-limit` options
87 check to see if the allowed time is over, which should make rsync exit more
90 - Tweak --progress to display "??:??:??" when the time-remaining value is
91 so large as to be meaningless.
95 - Use openssl's `-verify_hostname` option in the rsync-ssl script.
97 - Added extra info to the "FILENAME exists" output of `--ignore-existing` when
98 `--info=skip2` is used. The skip message becomes "FILENAME exists (INFO)"
99 where the INFO is one of "type change", "sum change" (requires `-c`), "file
100 change" (based on the quick check), "attr change", or "uptodate". Prior
101 versions only supported `--info=skip1`.
103 - Added the `--fsync` option (promoted from the patches repo).
105 - Reduced memory usage for an incremental transfer that has a bunch of small
108 - The rsync daemon can now handle a client address with an implied "%scope"
111 - Added support for `--atimes` on macOS and fixed a bug where it wouldn't work
114 - Rsync can now update the xattrs on a read-only file when your user can
115 temporarily add user-write permission to the file. (It always worked for a
118 - Rsync can now work around an `--inplace` update of a file that is being
119 refused due to the Linux fs.protected_regular sysctl setting.
121 - When `--chown`, `--usermap`, or `--groupmap` is specified, rsync now makes
122 sure that the appropriate `--owner` and/or `--group` option is enabled.
124 - Added the `--info=NONREG` setting to control if rsync should warn about
125 non-regular files in the transfer. This is enabled by default (keeping the
126 behavior the same as before), so specifying `--info=nonreg0` can be used to
127 turn the warnings off.
129 - More ASM optimizations from Shark64.
131 - Transformed rrsync into a python script with improvements:
132 - Security has been beefed up.
133 - The known rsync options were updated to include recent additions.
134 - Make rrsync reject `-L`, `-K`, & `-k` by default to make it harder to
135 exploit any out-of-subdir symlinks.
136 - A new rrsync option of `-munge` tells rrsync to always enable rsync's
137 `--munge-links` option on the server side.
138 - A new rrsync option of `-no-lock` disables a new single-use locking idiom
139 that is the default when `-ro` is not used (useful with `-munge`).
140 - A new rrsync option of `-no-del` disables all `--remove*` and `--delete*`
141 options on the server side.
142 - The log format has been tweaked slightly to add seconds to the timestamp
143 and to output the command executed as a tuple (making the args clearer).
144 - An rrsync.1 man page was added (in the support dir with rrsync).
146 - Added options to the lsh script to facilitate rrsync testing. (See the
149 - Transformed the atomic-rsync script into a python script and added the
150 ability to ignore one or more non-zero exit codes. By default, it now
151 ignores code 24, the file-vanished exit code. (See the support dir.)
153 - Transformed the munge-symlinks script into python. (See the support dir.)
155 - Improved the rsync-no-vanished script to not join stdout & stderr together.
156 (See the support dir.)
158 - Work around a glibc bug where lchmod() breaks in a chroot w/o /proc mounted.
160 - Try to support a client that sent a remote rsync a wacko stderr file handle
161 (such as an older File::RsyncP perl library used by BackupPC).
163 - Some man page improvements.
165 ### PACKAGING RELATED:
167 - Give configure the `--with-rrsync` option if you want `make install` to
168 install the (now python3) rrsync script and its new man page.
170 - If the rrsync script is installed, its package should be changed to depend
171 on python3 and the (suggested but not mandatory) python3 braceexpand lib.
173 - When creating a package from a non-release version (w/o a git checkout), the
174 packager can elect to create git-version.h and define RSYNC_GITVER to the
175 string they want `--version` to output. (The file is still auto-generated
176 using the output of `git describe` when building inside a non-shallow git
179 - Improved the IPv6 determination in configure.
181 - Made SIMD & ASM configure default to "no" on non-Linux hosts due to various
182 reports of problems on NetBSD & macOS hosts. These tests were also tweaked
183 to allow enabling the feature on a host_cpu of amd64 (was only x86_64).
185 - Fixed configure to not fail at the SIMD check when cross-compiling.
187 - Compile the C files with `-pedantic-errors` (when possible) so that we will
188 get warned if a static initialization overflows in the future (among other
191 - Added a SECURITY.md file.
193 ### DEVELOPER RELATED:
195 - Made it easier to write rsync tests that diff the output while also checking
196 the status code, and used the idiom to improve the existing tests. (See the
197 `checkdiff` and `checkdiff2` idioms in the `testsuite/*.test` files.
199 - The packaging scripts & related python lib got some minor enhancements.
203 - Use setenv() instead of putenv() when it is available.
205 - Improve the logic in compat.c so that we don't need to try to remember to
206 sprinkle `!local_server` exceptions throughout the protocol logic.
208 - One more C99 Flexible Array improvement (started in the last release) and
209 make use of the C99 `%zd` format string when printing size_t values (when
212 - Use mallinfo2() instead of mallinfo(), when available.
215 ------------------------------------------------------------------------------
217 # NEWS for rsync 3.2.3 (6 Aug 2020)
219 ## Changes in this version:
223 - Fixed a bug in the xattr code that was freeing the wrong object when trying
224 to cleanup the xattr list.
226 - Fixed a bug in the xattr code that was not leaving room for the "rsync."
227 prefix in some instances where it needed to be added.
229 - Restored the ability to use `--bwlimit=0` to specify no bandwidth limit. (It
230 was accidentally broken in 3.2.2.)
232 - Fixed a bug when combining `--delete-missing-args` with `--no-implied-dirs` &
233 `-R` where rsync might create the destination path of a missing arg. The
234 code also avoids some superfluous warnings for nested paths of removed args.
236 - Fixed an issue where hard-linked devices could cause the rdev_major value to
237 get out of sync between the sender and the receiver, which could cause a
238 device to get created with the wrong major value in its major,minor pair.
240 - Rsync now complains about a missing `--temp-dir` before starting any file
243 - A completely empty source arg is now a fatal error. This doesn't change
244 the handling of implied dot-dir args such as "localhost:" and such.
248 - Allow `--max-alloc=0` to specify no limit to the alloc sanity check.
250 - Allow `--block-size=SIZE` to specify the size using units (e.g. "100K").
252 - The name of the id-0 user & group are now sent to the receiver along with
253 the other user/group names in the transfer (instead of assuming that both
254 sides have the same id-0 names).
256 - Added the `--stop-after=MINS` and `--stop-at=DATE_TIME` options (with the
257 `--time-limit=MINS` option accepted as an alias for `--stop-after`). This
258 is an enhanced version of the time-limit patch from the patches repo.
260 - Added the `name converter` daemon parameter to make it easier to convert
261 user & group names inside a chrooted daemon module. This is based on the
262 nameconverter patch with some improvements, including a tweak to the request
263 protocol (so if you used this patch in the past, be sure to update your
264 converter script to use newlines instead of null chars).
266 - Added `--crtimes` (`-N`) option for preserving the file's create time (I
267 believe that this is macOS only at the moment).
269 - Added `--mkpath` option to tell rsync that it should create a non-existing
270 path component of the destination arg.
272 - Added `--stderr=errors|all|client` to replace the `--msgs2stderr` and
273 `--no-msgs2stderr` options (which are still accepted). The default use of
274 stderr was changed to be `--stderr=errors` where all the processes that have
275 stderr available output directly to stderr, which should help error messages
276 get to the user more quickly, especially when doing a push (which includes
277 local copying). This also allows rsync to exit quickly when a receiver
278 failure occurs, since rsync doesn't need to try to keep the connection alive
279 long enough for the fatal error to go from the receiver to the generator to
280 the sender. The old default can be requested via `--stderr=client`. Also
281 changed is that a non-default stderr mode is conveyed to the remote rsync
282 (using the older option names) instead of requiring the user to use
283 `--remote-option` (`-M`) to tell the remote rsync what to do.
285 - Added the ability to specify "@netgroup" names to the `hosts allow` and
286 `hosts deny` daemon parameters. This is a finalized version of the
287 netgroup-auth patch from the patches repo.
289 - Rsync can now hard-link symlinks on FreeBSD due to it making use of the
290 linkat() function when it is available.
292 - Output file+line info on out-of-memory & overflow errors while also avoiding
293 the output of alternate build-dir path info that is not useful to the user.
295 - Change configure to know that Cygwin supports Linux xattrs.
297 - Improved the testsuite on FreeBSD & Cygwin.
299 - Added some compatibility code for HPE NonStop platforms.
301 - Improved the INSTALL.md info.
303 - Added a few more suffixes to the default skip-compress list.
305 - Improved configure's error handling to notify about several issues at once
306 instead of one by one (for the newest optional features).
310 - Use a simpler overflow check idiom in a few spots.
312 - Use a C99 Flexible Array for a trailing variable-size filename in a struct
313 (with a fallback to the old 1-char string kluge for older compilers).
315 ------------------------------------------------------------------------------
317 # NEWS for rsync 3.2.2 (4 Jul 2020)
319 ## Changes in this version:
323 - Avoid a crash when a daemon module enables `transfer logging` without
324 setting a `log format` value.
326 - Fixed installing rsync-ssl script from an alternate build dir.
328 - Fixed the updating of configure.sh from an alternate build dir.
330 - Apple requires the asm function name to begin with an underscore.
332 - Avoid a test failure in the daemon test when `--atimes` is disabled.
336 - Allow the server side to restrict checksum & compression choices via the
337 same environment variables the client uses. The env vars can be divided
338 into "client list & server list" by the "`&`" char or the same list can
341 - Simplify how the negotiation environment variables apply when interacting
342 with an older rsync and also when a list contains only invalid names.
344 - Do not allow a negotiated checksum or compression choice of "none" unless
345 the user authorized it via an environment variable or command-line option.
347 - Added the `--max-alloc=SIZE` option to be able to override the memory
348 allocator's sanity-check limit. It defaults to 1G (as before) but the error
349 message when exceeding it specifically mentions the new option so that you
350 can differentiate an out-of-memory error from a failure of this limit. It
351 also allows you to specify the value via the RSYNC_MAX_ALLOC environment
354 - Add the "open atime" daemon parameter to allow a daemon to always enable or
355 disable the use of O_NOATIME (the default is to let the user control it).
357 - The default systemd config was changed to remove the `ProtectHome=on`
358 setting since rsync is often used to serve files in /home and /root and this
359 seemed a bit too strict. Feel free to use `systemctl edit rsync` to add
360 that restriction (or maybe `ProtectHome=read-only`), if you like. See the
361 3.2.0 NEWS for the other restrictions that were added compared to 3.1.3.
363 - The memory allocation functions now automatically check for a failure and
364 die when out of memory. This eliminated some caller-side check-and-die
365 code and added some missing sanity-checking of allocations.
367 - Put optimizations into their own list in the `--version` output.
369 - Improved the man page a bit more.
371 ### PACKAGING RELATED:
373 - Prepared the checksum code for an upcoming xxHash release that provides new
374 XXH3 (64-bit) & XXH128 (128-bit) checksum routines. These will not be
375 compiled into rsync until the xxhash v0.8.0 include files are installed on
376 the build host, and that release is a few weeks away at the time this was
377 written. So, if it's now the future and you have packaged and installed
378 xxhash-0.8.0-devel, a fresh rebuild of rsync 3.2.2 will give you the new
379 checksum routines. Just make sure that the new rsync package depends on
382 ### DEVELOPER RELATED:
384 - Moved the version number out of configure.ac into its own version.h file so
385 that we don't need to reconfigure just because the version number changes.
387 - Moved the daemon parameter list into daemon-parm.txt so that an awk script
388 can create the interrelated structs and accessors that loadparm.c needs.
390 ------------------------------------------------------------------------------
392 # NEWS for rsync 3.2.1 (22 Jun 2020)
394 ## Changes in this version:
398 - Fixed a potential build issue with the MD5 assembly-language code by
399 removing some non-portable directives.
401 - Use the preprocessor with the asm file to ensure that if the code is
402 unneeded, it doesn't get built.
404 - Avoid the stack getting set to executable when including the asm code.
406 - Some improvements in the SIMD configure testing to try to avoid build
407 issues, such as avoiding a clang++ core dump when `-g` is combined with
408 `-O2`. Note that clang++ is quite buggy in this area, and it does still
409 crash for some folks, so just use `--disable-simd` if you need to avoid
410 their buggy compiler (since the configure test is apparently not finding
411 all the compilers that will to crash and burn).
413 - Fixed an issue in the md2man script when building from an alternate dir.
415 - Disable `--atimes` on macOS (it apparently just ignores the atime change).
419 - The use of `--backup-dir=STR` now implies `--backup`.
421 - Added `--zl=NUM` as a short-hand for `--compress-level=NUM`.
423 - Added `--early-input=FILE` option that allows the client to send some
424 data to a daemon's (optional) "early exec" script on its stdin.
426 - Mention atimes in the capabilities list that `--version` outputs.
428 - Mention either "default protect-args" or "optional protect-args" in the
429 `--version` capabilities depending on how rsync was configured.
431 - Some info on optimizations is now elided from the `--version` capabilities
432 since they aren't really user-facing capabilities. You can still see the
433 info (plus the status of a couple extra optimizations) by repeating the
434 `--version` option (e.g. `-VV`).
436 - Updated various URLs to be https instead of http.
438 - Some documentation improvements.
440 ### PACKAGING RELATED:
442 - If you had to use `--disable-simd` for 3.2.0, you might want to try removing
443 that and see if it will succeed or auto-disable. Some buggy clang++
444 compilers are still not auto disabled, though.
446 - The MD5 asm code is now under its own configure flag (not shared with the
447 SIMD setting), so if you have any issues compiling it, re-run configure with
450 - Merged the OLDNEWS.md file into NEWS.md.
452 ------------------------------------------------------------------------------
454 # NEWS for rsync 3.2.0 (19 Jun 2020)
456 ## Changes in this version:
460 - Avoid a potential out-of-bounds read in daemon mode if argc can be made to
463 - Fix the default list of skip-compress files for non-daemon transfers.
465 - Fix xattr filter rules losing an 'x' attribute in a non-local transfer.
467 - Avoid an error when a check for a potential fuzzy file happens to reference
470 - Make the atomic-rsync helper script have a more consistent error-exit.
472 - Make sure that a signal handler's use of exit_cleanup() calls `_exit()`
475 - Various zlib fixes, including security fixes for CVE-2016-9843,
476 CVE-2016-9842, CVE-2016-9841, and CVE-2016-9840.
478 - Fixed an issue with `--remove-source-files` not removing a source symlink
479 when combined with `--copy-links`.
481 - Fixed a bug where the daemon would fail to write early fatal error messages
482 to the client, such as refused or unknown command-line options.
484 - Fixed the block-size validation logic when dealing with older protocols.
486 - Some rrsync fixes and enhancements to handle the latest options.
488 - Fixed a problem with the `--link-dest`|`--copy-dest` code when `--xattrs`
489 was specified along with multiple alternate-destination directories (it
490 could possibly choose a bad file match while trying to find a better xattr
493 - Fixed a couple bugs in the handling of files with the `--sparse` option.
495 - Fixed a bug in the writing of the batch.sh file (w/`--write-batch`) when the
496 source & destination args were not last on the command-line.
498 - Avoid a hang when an overabundance of messages clogs up all the I/O buffers.
500 - Fixed a mismatch in the RSYNC_PID values put into the environment of
501 `pre-xfer exec` and a `post-xfer exec`.
503 - Fixed a crash in the `--iconv` code.
505 - Fixed a rare crash in the popt_unalias() code.
509 - The default systemd config was made stricter by default. For instance,
510 `ProtectHome=on` (which hides content in /root and /home/USER dirs),
511 `ProtectSystem=full` (which makes /usr, /boot, & /etc dirs read-only), and
512 `PrivateDevices=on` (which hides devices). You can override any of these
513 using the standard `systemctl edit rsync` and add one or more directives
514 under a `[Service]` heading (and restart the rsync service).
516 - Various checksum enhancements, including the optional use of openssl's MD4 &
517 MD5 checksum algorithms, some x86-64 optimizations for the rolling checksum,
518 some x86-64 optimizations for the (non-openssl) MD5 checksum, the addition
519 of xxHash checksum support, and a negotiation heuristic that ensures that it
520 is easier to add new checksum algorithms in the future. The environment
521 variable `RSYNC_CHECKSUM_LIST` can be used to customize the preference order
522 of the negotiation, or use `--checksum-choice` (`--cc`) to force a choice.
524 - Various compression enhancements, including the addition of zstd and lz4
525 compression algorithms and a negotiation heuristic that picks the best
526 compression option supported by both sides. The environment variable
527 `RSYNC_COMPRESS_LIST` can be used to customize the preference order of the
528 negotiation, or use `--compress-choice` (`--zc`) to force a choice.
530 - Added a `--debug=NSTR` option that outputs details of the new negotiation
531 strings (for checksums and compression). The first level just outputs the
532 result of each negotiation on the client, level 2 outputs the values of the
533 strings that were sent to and received from the server, and level 3 outputs
534 all those values on the server side too (when the server was given the debug
537 - The `--debug=OPTS` command-line option is no longer auto-forwarded to the
538 remote rsync which allows for the client and server to have different levels
539 of debug specified. This also allows for newer debug options to be
540 specified, such as using `--debug=NSTR` to see the negotiated hash result,
541 without having the command fail if the server version is too old to handle
542 that debug item. Use `-M--debug=OPTS` to send the options to the remote side.
544 - Added the `--atimes` option based on the long-standing patch (just with some
545 fixes that the patch has been needing).
547 - Added `--open-noatime` option to open files using `O_NOATIME`.
549 - Added the `--write-devices` option based on the long-standing patch.
551 - Added openssl & preliminary gnutls support to the rsync-ssl script, which is
552 now installed by default. This was unified with the old stunnel-rsync
553 helper script to simplify packaging. Note that the script accepts the use
554 of `--type=gnutls` for gnutls testing, but does not look for gnutls-cli on
555 the path yet. The use of `--type=gnutls` will not work right until
556 gnutls-cli no longer drops data.
558 - Rsync was enhanced to set the `RSYNC_PORT` environment variable when running
559 a daemon-over-rsh script. Its value is the user-specified port number (set
560 via `--port` or an rsync:// URL) or 0 if the user didn't override the port.
562 - Added the `proxy protocol` daemon parameter that allows your rsyncd to know
563 the real remote IP when it is setup behind a proxy.
565 - Added negated matching to the daemon's `refuse options` setting by using
566 match strings that start with a `!` (such as `!compress*`). This lets you
567 refuse all options except for a particular approved list, for example. It
568 also lets rsync refuse certain options by default (such as `write-devices`)
569 while allowing the config to override that, as desired.
571 - Added the `early exec` daemon parameter that runs a script before the
572 transfer parameters are known, allowing some early setup based on module
575 - Added status output in response to a signal (via both SIGINFO & SIGVTALRM).
577 - Added `--copy-as=USER` option to give some extra security to root-run rsync
578 commands into/from untrusted directories (such as backups and restores).
580 - When resuming the transfer of a file in the `--partial-dir`, rsync will now
581 update that partial file in-place instead of creating yet another tmp file
582 copy. This requires both sender & receiver to be at least v3.2.0.
584 - Added support for `RSYNC_SHELL` & `RSYNC_NO_XFER_EXEC` environment variables
585 that affect the early, pre-xfer, and post-xfer exec rsync daemon parameters.
587 - Optimize the `--fuzzy --fuzzy` heuristic to avoid the fuzzy directory scan
588 until all other basis-file options are exhausted (such as `--link-dest`).
590 - Have the daemon log include the normal-exit sent/received stats when the
591 transfer exited with an error when possible (i.e. if it is the sender).
593 - The daemon now locks its pid file (when configured to use one) so that it
594 will not fail to start when the file exists but no daemon is running.
596 - Various man page improvements, including some html representations (that
597 aren't installed by default).
599 - Made `-V` the short option for `--version` and improved its information.
601 - Pass the `-4` or `-6` option to the ssh command, making it easier to type
602 than `--rsh='ssh -4'` (or the `-6` equivalent).
604 - Added example config for rsyncd SSL proxy configs to rsyncd.conf.
606 - More errors messages now mention if the error is coming from the sender or
609 ### PACKAGING RELATED:
611 - Add installed bash script: /usr/bin/rsync-ssl
613 - Add installed man page: /usr/man/man1/rsync-ssl.1
615 - Tweak auxiliary doc file names, such as: README.md, INSTALL.md, & NEWS.md.
617 - The rsync-ssl script wants to run openssl or stunnel4, so consider adding a
618 dependency for one of those options (though it's probably fine to just let
619 it complain about being unable to find the program and let the user decide
620 if they want to install one or the other).
622 - If you packaged rsync + rsync-ssl + rsync-ssl-daemon as separate packages,
623 the rsync-ssl package is now gone (rsync-ssl should be considered to be
624 mainstream now that Samba requires SSL for its rsync daemon).
626 - Add _build_ dependency for liblz4-dev, libxxhash-dev, libzstd-dev, and
627 libssl-dev. These development libraries will give rsync extra compression
628 algorithms, extra checksum algorithms, and allow use of openssl's crypto
629 lib for (potentially) faster MD4/MD5 checksums.
631 - Add _build_ dependency for g++ or clang++ on x86_64 systems to enable the
632 SIMD checksum optimizations.
634 - Add _build_ dependency for _either_ python3-cmarkcfm or python3-commonmark
635 to allow for patching of man pages or building a git release. This is not
636 required for a release-tar build, since it comes with pre-built man pages.
637 Note that cmarkcfm is faster than commonmark, but they generate the same
638 data. The commonmark dependency is easiest to install since it's native
639 python, and can even be installed via `pip3 install --user commonmark` if
640 you want to just install it for the build user.
642 - Remove yodl _build_ dependency (if it was even listed before).
644 ### DEVELOPER RELATED:
646 - Silenced some annoying warnings about major() & minor() by improving an
647 autoconf include-file check.
649 - Converted the man pages from yodl to markdown. They are now processed via a
650 simple python3 script using the cmarkgfm **or** commonmark library. This
651 should make it easier to package rsync, since yodl is rather obscure.
653 - Improved some configure checks to work better with strict C99 compilers.
655 - Some perl building/packaging scripts were recoded into awk and python3.
657 - Some defines in byteorder.h were changed into static inline functions that
658 will help to ensure that the args don't get evaluated multiple times on
659 "careful alignment" hosts.
661 - Some code typos were fixed (as pointed out by a Fossies run).
663 ------------------------------------------------------------------------------
665 # NEWS for rsync 3.1.3 (28 Jan 2018)
667 ## Changes in this version:
671 - Fixed a buffer overrun in the protocol's handling of xattr names and ensure
672 that the received name is null terminated.
674 - Fix an issue with `--protect-args` where the user could specify the arg in the
675 protected-arg list and short-circuit some of the arg-sanitizing code.
679 - Don't output about a new backup dir without appropriate info verbosity.
681 - Fixed some issues with the sort functions in the rsyncstats script (in the
684 - Added a way to specify daemon config lists (e.g. users, groups, etc) that
685 contain spaces (see `auth users` in the latest rsyncd.conf manpage).
687 - If a backup fails (e.g. full disk) rsync exits with an error.
689 - Fixed a problem with a doubled `--fuzzy` option combined with `--link-dest`.
691 - Avoid invalid output in the summary if either the start or end time had an
694 - We don't allow a popt alias to affect the `--daemon` or `--server` options.
696 - Fix daemon exclude code to disallow attribute changes in addition to
697 disallowing transfers.
699 - Don't force nanoseconds to match if a non-transferred, non-checksummed file
700 only passed the quick-check w/o comparing nanoseconds.
704 - Added the ability for rsync to compare nanosecond times in its file-check
705 comparisons, and added support nanosecond times on Mac OS X.
707 - Added a short-option (`-@`) for `--modify-window`.
709 - Added the `--checksum-choice=NAME[,NAME]` option to choose the checksum
712 - Added hashing of xattr names (with using `-X`) to improve the handling of
713 files with large numbers of xattrs.
715 - Added a way to filter xattr names using include/exclude/filter rules (see
716 the `--xattrs` option in the manpage for details).
718 - Added `daemon chroot|uid|gid` to the daemon config (in addition to the old
719 chroot|uid|gid settings that affect the daemon's transfer process).
721 - Added `syslog tag` to the daemon configuration.
723 - Some manpage improvements.
725 ### DEVELOPER RELATED:
727 - Tweak the `make` output when yodl isn't around to create the man pages.
729 - Changed an obsolete autoconf compile macro.
731 - Support newer yodl versions when converting man pages.
733 ------------------------------------------------------------------------------
735 # NEWS for rsync 3.1.2 (21 Dec 2015)
737 ## Changes in this version:
741 - Make sure that all transferred files use only path names from inside the
742 transfer. This makes it impossible for a malicious sender to try to make the
743 receiver use an unsafe destination path for a transferred file, such as a
748 - Change the checksum seed order in the per-block checksums. This prevents
749 someone from trying to create checksum blocks that match in sum but not
752 - Fixed a with the per-dir filter files (using `-FF`) that could trigger an
755 - Only skip `set_modtime()` on a transferred file if the time is exactly
758 - Don't create an empty backup dir for a transferred file that doesn't exist
761 - Fixed a bug where `--link-dest` and `--xattrs` could cause rsync to exit if
762 a filename had a matching dir of the same name in the alt-dest area.
764 - Allow more than 32 group IDs per user in the daemon's gid=LIST config.
766 - Fix the logging of %b & %c via `--log-file` (daemon logging was already
767 correct, as was `--out-format='%b/%c'`).
769 - Fix erroneous acceptance of `--info=5` & `--debug=5` (an empty flag name is
774 - Added `(DRY RUN)` info to the `--debug=exit` output line.
776 - Use usleep() for our msleep() function if it is available.
778 - Added a few extra long-option names to rrsync script, which will make
781 - Made configure choose to use Linux xattrs on NetBSD (rather than not
784 - Added `-wo` (write-only) option to rrsync support script.
786 - Misc. manpage tweaks.
788 ### DEVELOPER RELATED:
790 - Fixed a bug with the Makefile's use of `INSTALL_STRIP`.
792 - Improve a test in the suite that could get an erroneous timestamp error.
794 - Tweaks for newer versions of git in the packaging tools.
796 - Improved the m4 generation rules and some autoconf idioms.
798 ------------------------------------------------------------------------------
800 # NEWS for rsync 3.1.1 (22 Jun 2014)
802 ## Changes in this version:
806 - If the receiver gets bogus filenames from the sender (an unexpected leading
807 slash or a `..` infix dir), exit with an error. This prevents a malicious
808 sender from trying to inject filenames that would affect an area outside the
809 destination directories.
811 - Fixed a failure to remove the partial-transfer temp file when interrupted
812 (and rsync is not saving the partial files).
814 - Changed the chown/group/xattr-set order to avoid losing some security-
815 related xattr info (that would get cleared by a chown).
817 - Fixed a bug in the xattr-finding code that could make a non-root-run
818 receiver not able to find some xattr numbers.
820 - Fixed a bug in the early daemon protocol where a timeout failed to be
821 honored (e.g. if the remote side fails to send us the initial protocol
824 - Fixed unintended inclusion of commas in file numbers in the daemon log.
826 - We once again send the 'f' sub-flag (of `-e`) to the server side so it knows
827 that we can handle incremental-recursion directory errors properly in older
830 - Fixed an issue with too-aggressive keep-alive messages causing a problem for
831 older rsync versions early in the transfer.
833 - Fixed an incorrect message about backup-directory-creation when using
834 `--dry-run` and the backup dir is not an absolute path.
836 - Fixed a bug where a failed deletion and/or a failed sender-side removal
837 would not affect the exit code.
839 - Fixed a bug that caused a failure when combining `--delete-missing-args`
840 with `--xattrs` and/or `--acls`.
842 - Fixed a strange `dir_depth` assertion error that was caused by empty-dir
843 removals and/or duplicate files in the transfer.
845 - Fixed a problem with `--info=progress2`'s output stats where rsync would
846 only update the stats at the end of each file's transfer. It now uses the
847 data that is flowing for the current file, making the stats more accurate
850 - Fixed an itemize bug that affected the combo of `--link-dest`, `-X`, and
853 - Fixed a problem with delete messages not appearing in the log file when the
854 user didn't use `--verbose`.
856 - Improve chunked xattr reading for OS X.
858 - Removed an attempted hard-link xattr optimization that was causing a
859 transfer failure. This removal is flagged in the compatibility code, so if a
860 better fix can be discovered, we have a way to flip it on again.
862 - Fixed a bug when the receiver is not configured to be able to hard link
863 symlimks/devices/special-file items but the sender sent some of these items
864 flagged as hard-linked.
866 - We now generate a better error if the buffer overflows in `do_mknod()`.
868 - Fixed a problem reading more than 16 ACLs on some OSes.
870 - Fixed the reading of the secrets file to avoid an infinite wait when the
873 - Fixed a parsing problem in the `--usermap`/`--groupmap` options when using
876 - Switched Cygwin back to using socketpair `pipes` to try to speed it up.
878 - Added knowledge of a few new options to rrsync.
882 - Tweaked the temp-file naming when `--temp-dir=DIR` is used: the temp-file
883 names will not get a '.' prepended.
885 - Added support for a new-compression idiom that does not compress all the
886 matching data in a transfer. This can help rsync to use less cpu when a
887 transfer has a lot of matching data, and also makes rsync compatible with a
888 non-bundled zlib. See the `--new-compress` and `--old-compress` options in
891 - Added the rsync-no-vanished shell script. (See the support dir.)
893 - Made configure more prominently mention when we failed to find yodl (in case
894 the user wants to be able to generate manpages from `*.yo` files).
896 - Have manpage mention how a daemon's max-verbosity setting affects info and
897 debug options. Also added more clarification on backslash removals for
898 excludes that contain wildcards.
900 - Have configure check if for the attr lib (for getxattr) for those systems
901 that need to link against it explicitly.
903 - Change the early dir-creation logic to only use that idiom in an
904 inc-recursive copy that is preserving directory times. e.g. using
905 `--omit-dir-times` will avoid these early directories being created.
907 - Fix a bug in `cmp_time()` that would return a wrong result if the 2 times
908 differed by an amount greater than what a `time_t` can hold.
910 ### DEVELOPER RELATED:
912 - We now include an example systemd file (in packaging/systemd).
914 - Tweaked configure to make sure that any intended use of the included popt
915 and/or zlib code is put early in the CFLAGS.
917 ------------------------------------------------------------------------------
919 # NEWS for rsync 3.1.0 (28 Sep 2013)
921 ## Changes in this version:
925 - The protocol number was changed to 31.
929 - Output numbers in 3-digit groups by default (e.g. 1,234,567). See the
930 `--human-readable` option for a way to turn it off. See also the daemon's
931 `log format` parameter and related command-line options (including
932 `--out-format`) for a modifier that can be used to request digit-grouping or
933 human-readable output in log escapes. (Note that log output is unchanged by
936 - The `--list-only` option is now affected by the `--human-readable` setting.
937 It will display digit groupings by default, and unit suffixes if higher
938 levels of readability are requested. Also, the column width for the size
939 output has increased from 11 to 14 characters when human readability is
940 enabled. Use `--no-h` to get the old-style output and column size.
942 - The output of the `--progress` option has changed: the string `xfer` was
943 shortened to `xfr`, and the string `to-check` was shortened to `to-chk`,
944 both designed to make room for the (by default) wider display of file size
945 numbers without making the total line-length longer. Also, when incremental
946 recursion is enabled, the string `ir-chk` will be used instead of `to-chk`
947 up until the incremental-recursion scan is done, letting you know that the
948 value to check and the total value will still be increasing as new files are
951 - Enhanced the `--stats` output: 1) to mention how many files were created
952 (protocol >= 28), 2) to mention how many files were deleted (a new line for
953 protocol 31, but only output when `--delete` is in effect), and 3) to follow
954 the file-count, created-count, and deleted-count with a subcount list that
955 shows the counts by type. The wording of the transferred count has also
956 changed so that it is clearer that it is only a count of regular files.
960 - Fixed a bug in the iconv code when EINVAL or EILSEQ is returned with a full
963 - Fixed some rare bugs in `--iconv` processing that might cause a multi-byte
964 character to get translated incorrectly.
966 - Fixed a bogus `vanished file` error if some files were specified with `./`
967 prefixes and others were not.
969 - Fixed a bug in `--sparse` where an extra gap could get inserted after a
972 - Changed the way `--progress` overwrites its prior output in order to make it
973 nearly impossible for the progress to get overwritten by an error.
975 - Improved the propagation of abnormal-exit error messages. This should help
976 the client side to receive errors from the server when it is exiting
977 abnormally, and should also avoid dying with an `connection unexpectedly
978 closed` exit when the closed connection is really expected.
980 - The sender now checks each file it plans to remove to ensure that it hasn't
981 changed from the first stat's info. This helps to avoid losing file data
982 when the user is not using the option in a safe manner.
984 - Fixed a data-duplication bug in the compress option that made compression
985 less efficient. This improves protocol 31 onward, while behaving in a
986 compatible (buggy) manner with older rsync protocols.
988 - When creating a temp-file, rsync is now a bit smarter about it dot-char
989 choices, which can fix a problem on OS X with names that start with `..`.
991 - Rsync now sets a cleanup flag for `--inplace` and `--append` transfers that
992 will flush the write buffer if the transfer aborts. This ensures that more
993 received data gets written out to the disk on an aborted transfer (which is
994 quite helpful on a slow, flaky connection).
996 - The reads that `map_ptr()` now does are aligned on 1K boundaries. This helps
997 some filesystems and/or files that don't like unaligned reads.
999 - Fix an issue in the msleep() function if time jumps backwards.
1001 - Fix daemon-server module-name splitting bug where an arg would get split
1002 even if `--protect-args` was used.
1006 - Added the `--remote-option=OPT` (`-M OPT`) command-line option that is
1007 useful for things like sending a remote `--log-file=FILE` or `--fake-super`
1010 - Added the `--info=FLAGS` and `--debug=FLAGS` options to allow finer-grained
1011 control over what is output. Added an extra type of `--progress` output
1012 using `--info=progress2`.
1014 - The `--msgs2stderr` option can help with debugging rsync by allowing the
1015 debug messages to get output to stderr rather than travel via the socket
1018 - Added the `--delete-missing-args` and `--ignore-missing-args` options to
1019 either delete or ignore user-specified files on the receiver that are
1020 missing on the sender (normally the absence of user-specified files
1021 generates an error).
1023 - Added a `T` (terabyte) category to the `--human-readable` size suffixes.
1025 - Added the `--usermap`/`--groupmap`/`--chown` options for manipulating file
1026 ownership during the copy.
1028 - Added the `%C` escape to the log-output handling, which will output the MD5
1029 checksum of any transferred file, or all files if `--checksum` was specified
1030 (when protocol 30 or above is in effect).
1032 - Added the `reverse lookup` parameter to the rsync daemon config file to
1033 allow reverse-DNS lookups to be disabled.
1035 - Added a forward-DNS lookup for the daemon's hosts allow/deny config. Can be
1036 disabled via `forward lookup` parameter (defaults to enabled).
1038 - Added a way for more than one group to be specified in the daemon's config
1039 file, including a way to specify that you want all of the specified user's
1040 groups without having to name them. Also changed the daemon to complain
1041 about an inability to set explicitly-specified uid/gid values, even when not
1042 run by a super-user.
1044 - The daemon now tries to send the user the error messages from the pre-xfer
1045 exec script when it fails.
1047 - Improved the use of alt-dest options into an existing hierarchy of files: If
1048 a match is found in an alt-dir, it takes precedence over an existing file.
1049 (We'll need to wait for a future version before attribute-changes on
1050 otherwise unchanged files are safe when using an existing hierarchy.)
1052 - Added per-user authorization options and group-authorization support to the
1053 daemon's `auth users` parameter.
1055 - Added a way to reference environment variables in a daemon's config file
1056 (using %VAR% references).
1058 - When replacing a non-dir with a symlink/hard-link/device/special-file, the
1059 update should now be done in an atomic manner.
1061 - Avoid re-sending xattr info for hard-linked files w/the same xattrs
1064 - The backup code was improved to use better logic maintaining the backup
1065 directory hierarchy. Also, when a file is being backed up, rsync tries to
1066 hard-link it into place so that the upcoming replacement of the destination
1067 file will be atomic (for the normal, non-inplace logic).
1069 - Added the ability to synchronize nanosecond modified times.
1071 - Added a few more default suffixes for the `dont compress` settings.
1073 - Added the checking of the `RSYNC_PROTECT_ARGS` environment variable to allow
1074 the default for the `--protect-args` command-line option to be overridden.
1076 - Added the `--preallocate` command-line option.
1078 - Allow `--password-file=-` to read the password from stdin (filename `-`).
1080 - Rsync now comes packaged with an rsync-ssl helper script that can be used to
1081 contact a remote rsync daemon using a piped-stunnel command. It also
1082 includes an stunnel config file to run the server side to support ssl daemon
1083 connections. See the packaging/lsb/rsync.spec file for one way to package
1084 the resulting files. (Suggestions for how to make this even easier to
1085 install & use are welcomed.)
1087 - Improved the speed of some `--inplace` updates when there are lots of
1088 identical checksum blocks that end up being unusable.
1090 - Added the `--outbuf=N|L|B` option for choosing the output buffering.
1092 - Repeating the `--fuzzy` option now causes the code to look for fuzzy matches
1093 inside alt-dest directories too.
1095 - The `--chmod` option now supports numeric modes, e.g. `--chmod=644,D755`
1097 - Added some Solaris xattr code.
1099 - Made an rsync daemon (the listening process) exit with a 0 status when it
1100 was signaled to die. This helps launchd.
1102 - Improved the `RSYNC_*` environment variables for the pre-xfer exec script:
1103 when a daemon is sent multiple request args, they are now joined into a
1104 single return value (separated by spaces) so that the `RSYNC_REQUEST`
1105 environment variable is accurate for any `pre-xfer exec`. The values in
1106 `RSYNC_ARG#` vars are no longer truncated at the `.` arg (prior to the
1107 request dirs/files), so that all the requested values are also listed
1108 (separately) in `RSYNC_ARG#` variables.
1112 - Added an `instant-rsyncd` script to the support directory, which makes it
1113 easy to configure a simple rsync daemon in the current directory.
1115 - Added the `mapfrom` and `mapto` scripts to the support directory, which
1116 makes it easier to do user/group mapping in a local transfer based on
1117 passwd/group files from another machine.
1119 - There's a new, improved version of the lsh script in the support dir: it's
1120 written in perl and supports `-u` without resorting to using sudo (when run
1121 as root). The old shell version is now named lsh.sh.
1123 - There is a helper script named rsync-slash-strip in the support directory
1124 for anyone that wants to change the way rsync handles args with trailing
1125 slashes. (e.g. arg/ would get stripped to arg while arg/. would turn into
1130 - The I/O code was rewritten to be simpler and do bigger buffered reads over
1131 the socket. The I/O between the receiver and the generator was changed to be
1132 standard multiplexed-I/O (like that over the socket).
1134 - The sender tries to use any dead time while the generator is looking for
1135 files to transfer in order to do sender-side directory scanning in a more
1138 - A daemon can now inform a client about a daemon-configured timeout value so
1139 that the client can assist in the keep-alive activity (protocol 31).
1141 - The filter code received some refactoring to make it more extendable, to
1142 read better, and do better sanity checking.
1144 - Really big numbers are now output using our own big-num routine rather than
1145 casting them to a double and using a %.0f conversion.
1147 - The `pool_alloc` library has received some minor improvements in alignment
1150 - Added `init_stat_x()` function to avoid duplication of acl/xattr init code.
1152 - The included zlib was upgraded from 1.2.3 to 1.2.8.
1154 - Rsync can now be compiled to use an unmodified zlib library instead of the
1155 tweaked one that is included with rsync. This will eventually become the
1156 default, at which point we'll start the countdown to removing the included
1157 zlib. Until then, feel free to configure using:
1159 ./configure `--with-included-zlib=no`
1161 ### DEVELOPER RELATED:
1163 - Added more conditional debug output.
1165 - Fixed some build issues for Android and Minix.
1167 ------------------------------------------------------------------------------
1169 # NEWS for rsync 3.0.9 (23 Sep 2011)
1171 ## Changes in this version:
1175 - Fix a crash bug in checksum scanning when `--inplace` is used.
1177 - Fix a hang if a hard-linked file cannot be opened by the sender (e.g. if it
1178 has no read permission).
1180 - Fix preservation of a symlink's system xattrs (e.g. selinux) on Linux.
1182 - Fix a memory leak in the xattr code.
1184 - Fixed a bug with `--delete-excluded` when a filter merge file has a rule
1185 that specifies a receiver-only side restriction.
1187 - Fix a bug with the modifying of unwritable directories.
1189 - Fix `--fake-super`'s interaction with `--link-dest` same-file comparisons.
1191 - Fix the updating of the `curr_dir` buffer to avoid a duplicate slash.
1193 - Fix the directory permissions on an implied dot-dir when using `--relative`
1194 (e.g. /outside/path/././send/path).
1196 - Fixed some too-long sleeping instances when using `--bwlimit`.
1198 - Fixed when symlink ownership difference-checking gets compiled into
1199 `unchanged_attrs()`.
1201 - Improved the socket-error reporting when multiple protocols fail.
1203 - Fixed a case where a socket error could reference just-freed memory.
1205 - Failing to use a password file that was specified on the command-line is now
1208 - Fix the non-root updating of directories that don't have the read and/or
1211 - Make daemon-excluded file errors more error-like.
1213 - Fix a compilation issue on older C compilers (due to a misplaced var
1216 - Make configure avoid finding socketpair on Cygwin.
1218 - Avoid trying to reference `SO_BROADCAST` if the OS doesn't support it.
1220 - Fix some issues with the post-processing of the man pages.
1222 - Fixed the user home-dir handling in the lsh script. (See the support dir.)
1224 - Some minor manpage improvements.
1226 ------------------------------------------------------------------------------
1228 # NEWS for rsync 3.0.8 (26 Mar 2011)
1230 ## Changes in this version:
1234 - Fixed two buffer-overflow issues: one where a directory path that is exactly
1235 MAXPATHLEN was not handled correctly, and one handling a `--backup-dir` that
1236 is extra extra large.
1238 - Fixed a data-corruption issue when preserving hard-links without preserving
1239 file ownership, and doing deletions either before or during the transfer
1240 (CVE-2011-1097). This fixes some assert errors in the hard-linking code, and
1241 some potential failed checksums (via `-c`) that should have matched.
1243 - Fixed a potential crash when an rsync daemon has a filter/exclude list and
1244 the transfer is using ACLs or xattrs.
1246 - Fixed a hang if a really large file is being processed by an rsync that
1247 can't handle 64-bit numbers. Rsync will now complain about the file being
1248 too big and skip it.
1250 - For devices and special files, we now avoid gathering useless ACL and/or
1251 xattr information for files that aren't being copied. (The un-copied files
1252 are still put into the file list, but there's no need to gather data that is
1253 not going to be used.) This ensures that if the user uses `--no-D`, that
1254 rsync can't possibly complain about being unable to gather extended
1255 information from special files that are in the file list (but not in the
1258 - Properly handle requesting remote filenames that start with a dash. This
1259 avoids a potential error where a filename could be interpreted as a (usually
1262 - Fixed a bug in the comparing of upper-case letters in file suffixes for
1265 - If an rsync daemon has a module configured without a path setting, rsync
1266 will now disallow access to that module.
1268 - If the destination arg is an empty string, it will be treated as a reference
1269 to the current directory (as 2.x used to do).
1271 - If rsync was compiled with a newer time-setting function (such as lutimes),
1272 rsync will fall-back to an older function (such as utimes) on a system where
1273 the newer function is not around. This helps to make the rsync binary more
1274 portable in mixed-OS-release situations.
1276 - Fixed a batch-file writing bug that would not write out the full set of
1277 compatibility flags that the transfer was using. This fixes a potential
1278 protocol problem for a batch file that contains a sender-side I/O error: it
1279 would have been sent in a way that the batch-reader wasn't expecting.
1281 - Some improvements to the hard-linking code to ensure that device-number
1282 hashing is working right, and to supply more information if the hard-link
1285 - The `--inplace` code was improved to not search for an impossible checksum
1286 position. The quadruple-verbose chunk[N] message will now mention when an
1287 inplace chunk was handled by a seek rather than a read+write.
1289 - Improved ACL mask handling, e.g. for Solaris.
1291 - Fixed a bug that prevented `--numeric-ids` from disabling the translation of
1292 user/group IDs for ACLs.
1294 - Fixed an issue where an xattr and/or ACL transfer that used an alt-dest
1295 option (e.g. `--link-dest`) could output an error trying to itemize the
1296 changes against the alt-dest directory's xattr/ACL info but was instead
1297 trying to access the not-yet-existing new destination directory.
1299 - Improved xattr system-error messages to mention the full path to the file.
1301 - The `--link-dest` checking for identical symlinks now avoids considering
1302 attribute differences that cannot be changed on the receiver.
1304 - Avoid trying to read/write xattrs on certain file types for certain OSes.
1305 Improved configure to set `NO_SYMLINK_XATTRS`, `NO_DEVICE_XATTRS`, and/or
1306 `NO_SPECIAL_XATTRS` defines in config.h.
1308 - Improved the unsafe-symlink errors messages.
1310 - Fixed a bug setting xattrs on new files that aren't user writable.
1312 - Avoid re-setting xattrs on a hard-linked file w/the same xattrs.
1314 - Fixed a bug with `--fake-super` when copying files and dirs that aren't user
1317 - Fixed a bug where a sparse file could have its last sparse block turned into
1318 a real block when rsync sets the file size (requires ftruncate).
1320 - If a temp-file name is too long, rsync now avoids truncating the name in the
1321 middle of adjacent high-bit characters. This prevents a potential filename
1322 error if the filesystem doesn't allow a name to contain an invalid
1323 multi-byte sequence.
1325 - If a muli-protocol socket connection fails (i.e., when contacting a daemon),
1326 we now report all the failures, not just the last one. This avoids losing a
1327 relevant error (e.g. an IPv4 connection-refused error) that happened before
1328 the final error (e.g. an IPv6 protocol-not-supported error).
1330 - Generate a transfer error if we try to call chown with a `-1` for a uid or a
1331 gid (which is not settable).
1333 - Fixed the working of `--force` when used with `--one-file-system`.
1335 - Fix the popt arg parsing so that an option that doesn't take an arg will
1336 reject an attempt to supply one (can configure `--with-included-popt` if
1337 your system's popt library doesn't yet have this fix).
1339 - A couple minor option tweaks to the rrsync script, and also some regex
1340 changes that make vim highlighting happier. (See the support dir.)
1342 - Fixed some issues in the mnt-excl script. (See the support dir.)
1344 - Various manpage improvements.
1348 - Added `.hg/` to the default cvs excludes (see `-C` & `--cvs-exclude`).
1350 ### DEVELOPER RELATED:
1352 - Use lchmod() whenever it is available (not just on symlinks).
1354 - A couple fixes to the `socketpair_tcp()` routine.
1356 - Updated the helper scripts in the packaging subdirectory.
1358 - Renamed configure.in to configure.ac.
1360 - Fixed configure's checking for iconv routines for newer OS X versions.
1362 - Fixed the testsuite/xattrs.test script on OS X.
1364 ------------------------------------------------------------------------------
1366 # NEWS for rsync 3.0.7 (31 Dec 2009)
1368 ## Changes in this version:
1372 - Fixed a bogus free when using `--xattrs` with `--backup`.
1374 - Avoid an error when `--dry-run` was trying to stat a prior hard-link file
1375 that hasn't really been created.
1377 - Fixed a problem with `--compress` (`-z`) where the receiving side could
1378 return the error "`inflate (token) returned -5`".
1380 - Fixed a bug where `--delete-during` could delete in a directory before it
1381 noticed that the sending side sent an I/O error for that directory (both
1382 sides of the transfer must be at least 3.0.7).
1384 - Improved `--skip-compress`'s error handling of bad character-sets and got
1385 rid of a lingering debug fprintf().
1387 - Fixed the daemon's conveyance of `io_error` value from the sender.
1389 - An rsync daemon use seteuid() (when available) if it used setuid().
1391 - Get the permissions right on a `--fake-super` transferred directory that
1392 needs more owner permissions to emulate root behavior.
1394 - An absolute-path filter rule (i.e. with a '/' modifier) no longer loses its
1395 modifier when sending the filter rules to the remote rsync.
1397 - Improved the "`--delete does not work without -r or -d`" message.
1399 - Improved rsync's handling of `--timeout` to avoid a weird timeout case where
1400 the sender could timeout even though it has recently written data to the
1401 socket (but hasn't read data recently, due to the writing).
1403 - Some misc manpage improvements.
1405 - Fixed the chmod-temp-dir testsuite on a system without /var/tmp.
1407 - Make sure that a timeout specified in the daemon's config is used as a
1408 maximum timeout value when the user also specifies a timeout.
1410 - Improved the error-exit reporting when rsync gets an error trying to cleanup
1411 after an error: the initial error is reported.
1413 - Improved configure's detection of IPv6 for Solaris and Cygwin.
1415 - The AIX sysacls routines will now return ENOSYS if ENOTSUP is missing.
1417 - Made our (only used if missing) getaddrinfo() routine use `inet_pton()`
1418 (which we also provide) instead of `inet_aton()`.
1420 - The exit-related debug messages now mention the program's role so it is
1421 clear who output what message.
1423 ### DEVELOPER RELATED:
1425 - Got rid of type-punned compiler warnings output by newer gcc versions.
1427 - The Makefile now ensures that proto.h will be rebuilt if config.h changes.
1429 - The testsuite no longer uses `id -u`, so it works better on Solaris.
1431 ------------------------------------------------------------------------------
1433 # NEWS for rsync 3.0.6 (8 May 2009)
1435 ## Changes in this version:
1439 - Fixed a `--read-batch` hang when rsync is reading a batch file that was
1440 created from an incremental-recursion transfer.
1442 - Fixed the daemon's socket code to handle the simultaneous arrival of
1443 multiple connections.
1445 - Fix `--safe-links`/`--copy-unsafe-links` to properly handle symlinks that
1446 have consecutive slashes in the value.
1448 - Fixed the parsing of an `[IPv6_LITERAL_ADDR]` when a USER@ is prefixed.
1450 - The sender now skips a (bogus) symlink that has a 0-length value, which
1451 avoids a transfer error in the receiver.
1453 - Fixed a case where the sender could die with a tag-0 error if there was an
1454 I/O during the sending of the file list.
1456 - Fixed the rrsync script to avoid a server-side problem when `-e` is at the
1457 start of the short options.
1459 - Fixed a problem where a vanished directory could turn into an exit code 23
1460 instead of the proper exit code 24.
1462 - Fixed the `--iconv` conversion of symlinks when doing a local copy.
1464 - Fixed a problem where `--one-file-system` was not stopping deletions on the
1465 receiving side when a mount-point directory did not match a directory in the
1468 - Fixed the dropping of an ACL mask when no named ACL values were present.
1470 - Fixed an ACL/xattr corruption issue where the `--backup` option could cause
1471 rsync to associate the wrong ACL/xattr information with received files.
1473 - Fixed the use of `--xattrs` with `--only-write-batch`.
1475 - Fixed the use of `--dry-run` with `--read-batch`.
1477 - Fixed configure's erroneous use of target.
1479 - Fixed configure's `--disable-debug` option.
1481 - Fixed a run-time issue for systems that can't find `iconv_open()` by adding
1482 the `--disable-iconv-open` configure option.
1484 - Complain and die if the user tries to combine `--remove-source-files` (or
1485 the deprecated `--remove-sent-files`) with `--read-batch`.
1487 - Fixed an failure transferring special files from Solaris to Linux.
1489 ------------------------------------------------------------------------------
1491 # NEWS for rsync 3.0.5 (28 Dec 2008)
1493 ## Changes in this version:
1497 - Initialize xattr data in a couple spots in the hlink code, which avoids a
1498 crash when the xattr pointer's memory happens to start out non-zero. Also
1499 fixed the itemizing of an alt-dest file's xattrs when hard-linking.
1501 - Don't send a bogus `-` option to an older server if there were no short
1504 - Fixed skipping of unneeded updates in a batch file when incremental
1505 recursion is active. Added a test for this. Made batch-mode handle `redo`
1506 files properly (and without hanging).
1508 - Fix the %P logfile escape when the daemon logs from inside a chroot.
1510 - Fixed the use of `-s` (`--protect-args`) when used with a remote source or
1511 destination that had an empty path (e.g. `host:`). Also fixed a problem when
1512 `-s` was used when accessing a daemon via a remote-shell.
1514 - Fixed the use of a dot-dir path (e.g. foo/./bar) inside a `--files-from`
1515 file when the root of the transfer isn't the current directory.
1517 - Fixed a bug with `-K --delete` removing symlinks to directories when
1518 incremental recursion is active.
1520 - Fixed a hard to trigger hang when using `--remove-source-files`.
1522 - Got rid of an annoying delay when accessing a daemon via a remote-shell.
1524 - Properly ignore (superfluous) source args on a `--read-batch` command.
1526 - Improved the manpage's description of the `*` wildcard to remove the
1527 confusing `non-empty` qualifier.
1529 - Fixed reverse lookups in the compatibility-library version of getnameinfo().
1531 - Fixed a bug when using `--sparse` on a sparse file that has over 2GB of
1532 consecutive sparse data.
1534 - Avoid a hang when using at least 3 `--verbose` options on a transfer with a
1535 client sender (which includes local copying).
1537 - Fixed a problem with `--delete-delay` reporting an error when it was ready
1538 to remove a directory that was now gone.
1540 - Got rid of a bunch of `warn_unused_result` compiler warnings.
1542 - If an ftruncate() on a received file fails, it now causes a partial-
1545 - Allow a path with a leading `//` to be preserved (CYGWIN only).
1549 - Made the atomic-rsync script able to perform a fully atomic update of the
1550 copied hierarchy when the destination is setup using a particular symlink
1551 idiom. (See the support dir.)
1553 ------------------------------------------------------------------------------
1555 # NEWS for rsync 3.0.4 (6 Sep 2008)
1557 ## Changes in this version:
1561 - Fixed a bug in the hard-linking code where it would sometimes try to
1562 allocate 0 bytes of memory (which fails on some OSes, such as AIX).
1564 - Fixed the hard-linking of files from a device that has a device number of 0
1565 (which seems to be a common device number on NetBSD).
1567 - Fixed the handling of a `--partial-dir` that cannot be created. This
1568 particularly impacts the `--delay-updates` option (since the files cannot be
1569 delayed without a partial-dir), and was potentially destructive if the
1570 `--remove-source-files` was also specified.
1572 - Fixed a couple issues in the `--fake-super` handling of xattrs when the
1573 destination files have root-level attributes (e.g. selinux values) that a
1574 non-root copy can't affect.
1576 - Improved the keep-alive check in the generator to fire consistently in
1577 incremental-recursion mode when `--timeout` is enabled.
1579 - The `--iconv` option now converts the content of a symlink too, instead of
1580 leaving it in the wrong character-set (requires 3.0.4 on both sides of the
1583 - When using `--iconv`, if a filename fails to convert on the receiving side,
1584 this no longer makes deletions in the root-dir of the transfer fail silently
1585 (the user now gets a warning about deletions being disabled due to IO error
1586 as long as `--ignore-errors` was not specified).
1588 - When using `--iconv`, if a server-side receiver can't convert a filename,
1589 the error message sent back to the client no longer mangles the name with
1590 the wrong charset conversion.
1592 - Fixed a potential alignment issue in the IRIX ACL code when allocating the
1593 initial `struct acl` object. Also, cast mallocs to avoid warnings.
1595 - Changed some errors that were going to stdout to go to stderr.
1597 - Made `human_num()` and `human_dnum()` able to output a negative number
1598 (rather than outputting a cryptic string of punctuation).
1602 - Rsync will avoid sending an `-e` option to the server if an older protocol
1603 is requested (and thus the option would not be useful). This lets the user
1604 specify the `--protocol=29` option to access an overly-restrictive server
1605 that is rejecting the protocol-30 use of `-e` to the server.
1607 - Improved the message output for an `RERR_PARTIAL` exit.
1609 ### DEVELOPER RELATED:
1611 - The Makefile will not halt for just a timestamp change on the Makefile or
1612 the configure files, only for actual changes in content.
1614 - Changed some commands in the testsuite's xattrs.test that called `rsync`
1615 instead of `$RSYNC`.
1617 - Enhanced the release scripts to be able to handle a branch release and to do
1618 even more consistency checks on the files.
1620 ------------------------------------------------------------------------------
1622 # NEWS for rsync 3.0.3 (29 Jun 2008)
1624 ## Changes in this version:
1628 - Fixed a wildcard matching problem in the daemon when a module has `use
1631 - Fixed a crash bug in the hard-link code.
1633 - Fixed the sending of xattr directory information when the code finds a
1634 `--link-dest` or `--copy-dest` directory with unchanged xattrs -- the
1635 destination directory now gets these unchanged xattrs properly applied.
1637 - Fixed an xattr-sending glitch that could cause an `Internal abbrev` error.
1639 - Fixed the combination of `--xattrs` and `--backup`.
1641 - The generator no longer allows a '.' dir to be excluded by a daemon-exclude
1644 - Fixed deletion handling when copying a single, empty directory (with no
1645 files) to a differently named, non-existent directory.
1647 - Fixed the conversion of spaces into dashes in the %M log escape.
1649 - Fixed several places in the code that were not returning the right errno
1650 when a function failed.
1652 - Fixed the backing up of a device or special file into a backup dir.
1654 - Moved the setting of the socket options prior to the connect().
1656 - If rsync exits in the middle of a `--progress` output, it now outputs a
1657 newline to help prevent the progress line from being overwritten.
1659 - Fixed a problem with how a destination path with a trailing slash or a
1660 trailing dot-dir was compared against the daemon excludes.
1662 - Fixed the sending of large (size > 16GB) files when talking to an older
1663 rsync (protocols < 30): we now use a compatible block size limit.
1665 - If a file's length is so huge that we overflow a checksum buffer count (i.e.
1666 several hundred TB), warn the user and avoid sending an invalid checksum
1667 struct over the wire.
1669 - If a source arg is excluded, `--relative` no longer adds the excluded arg's
1670 implied dirs to the transfer. This fix also made the exclude check happen in
1671 the better place in the sending code.
1673 - Use the `overflow_exit()` function for overflows, not `out_of_memory()`.
1675 - Improved the code to better handle a system that has only 32-bit file
1680 - The rsyncd.conf manpage now consistently refers to the parameters in the
1681 daemon config file as `parameters`.
1683 - The description of the `--inplace` option was improved.
1687 - Added a new script in the support directory, deny-rsync, which allows an
1688 admin to (temporarily) replace the rsync command with a script that sends an
1689 error message to the remote client via the rsync protocol.
1691 ### DEVELOPER RELATED:
1693 - Fixed a testcase failure if the tests are run as root and made some
1694 compatibility improvements.
1696 - Improved the daemon tests, including checking module comments, the listing
1697 of files, and the ensuring that daemon excludes can't affect a dot-dir arg.
1699 - Improved some build rules for those that build in a separate directory from
1700 the source, including better install rules for the man pages, and the fixing
1701 of a proto.h-tstamp rule that could make the binaries get rebuild without
1704 - Improved the testsuite to work around a problem with some utilities (e.g.
1705 `cp -p` & `touch -r`) rounding sub-second timestamps.
1707 - Ensure that the early patches don't cause any generated-file hunks to
1708 bleed-over into patches that follow.

1712 # NEWS for rsync 3.0.2 (8 Apr 2008)
1714 ## Changes in this version:

1733 # NEWS for rsync 3.0.1 (3 Apr 2008)
1735 ## Changes in this version:
1737 ### NOTABLE CHANGES IN BEHAVIOR:
1739 - Added the 'c'-flag to the itemizing of non-regular files so that the
1740 itemized output doesn't get hidden if there were no attribute changes, and
1741 also so that the itemizing of a `--copy-links` run will distinguish between
1742 copying an identical non-regular file and the creation of a revised version
1743 with a new value (e.g. a changed symlink referent, a new device number,
1748 - Fixed a crash bug when a single-use rsync daemon (via remote shell) was run
1749 without specifying a `--config=FILE` option.
1751 - Fixed a crash when backing up a directory that has a default ACL.
1753 - Fixed a bug in the handling of xattr values that could cause rsync to not
1754 think that a file's extended attributes are up-to-date.
1756 - Fixed the working of `--fake-super` with `--link-dest` and `--xattrs`.
1758 - Fixed a hang when combining `--dry-run` with `--remove-source-files`.
1760 - Fixed a bug with `--iconv`'s handling of files that cannot be converted: a
1761 failed name can no longer cause a transfer failure.
1763 - Fixed the building of the rounding.h file on systems that need custom
1764 CPPFLAGS to be used. Also improved the error reporting if the building of
1767 - Fixed the use of the `--protect-args` (`-s`) option when talking to a
1770 - Fixed the `--ignore-existing` option's protection of files on the receiver
1771 that are non-regular files on the sender (e.g. if a symlink or a dir on the
1772 sender is trying to replace a file on the receiver). The reverse protection
1773 (protecting a dir/symlink/device from being replaced by a file) was already
1776 - Fixed an assert failure if `--hard-links` is combined with an option that
1777 can skip a file in a set of hard-linked files (i.e. `--ignore-existing`,
1778 `--append`, etc.), without skipping all the files in the set.
1780 - Avoid setting the modify time on a directory that already has the right
1781 modify time set. This avoids tweaking the dir's ctime.
1783 - Improved the daemon-exclude handling to do a better job of applying the
1784 exclude rules to path entries. It also sends the user an error just as if
1785 the files were actually missing (instead of silently ignoring the user's
1786 args), and avoids sending the user the filter-action messages for these
1787 non-user-initiated rules.
1789 - Fixed some glitches with the dry-run code's missing-directory handling,
1790 including a problem when combined with `--fuzzy`.
1792 - Fixed some glitches with the skipped-directory handling.
1794 - Fixed the 'T'-flag itemizing of symlinks when `--time` isn't preserved.
1796 - Fixed a glitch in the itemizing of permissions with the `-E` option.
1798 - The `--append` option's restricting of transfers to those that add data no
1799 longer prevents the updating of non-content changes to otherwise up-to-date
1800 files (i.e. those with the same content but differing permissions,
1801 ownership, xattrs, etc.).
1803 - Don't allow `--fake-super` to be specified with `-XX` (double `--xattrs`)
1804 because the options conflict. If a daemon has `fake super` enabled, it
1805 automatically downgrades a `-XX` request to `-X`.
1807 - Fixed a couple bugs in the parsing of daemon-config excludes that could make
1808 a floating exclude rule get treated as matching an absolute path.
1810 - A daemon doesn't try to auto-refuse the `iconv` option if iconv-support
1811 wasn't compiled in to the daemon (avoiding a warning in the logs).
1813 - Fixed the inclusion of per-dir merge files from implied dirs.
1815 - Fixed the rrsync script to work with the latest options that rsync sends,
1816 including its flag-specifying use of `-e` to the server. (See the support
1821 - Added the `--old-dirs` (`--old-d`) option to make it easier for a user to
1822 ask for file-listings with older rsync versions (this is easier than having
1823 to type `-r --exclude='/*/*'` manually).
1825 - When getting an error while asking an older rsync daemon for a file listing,
1826 rsync will try to notice if the error is a rejection of the `--dirs` (`-d`)
1827 option and let the user know how to work around the issue.
1829 - Added a few more `--no-OPTION` overrides.
1831 - Improved the documentation of the `--append` option.
1833 - Improved the documentation of the filter/exclude/include daemon parameters.
1837 - Fixed a couple minor bugs in the included popt library (ones which I sent to
1838 the official popt project for inclusion in the 1.14 release).
1840 - Fixed a stat() call that should have been `do_stat()` so that the proper
1841 normal/64-bit stat() function gets called. (Was in an area that should not
1842 have caused problems, though.)
1844 - Changed the file-glob code to do a directory scan without using the `glob`
1845 and `glob.h`. This lets us do the globbing with less memory churn, and also
1846 avoid adding daemon-excluded items to the returned args.
1848 ### DEVELOPER RELATED:
1850 - The configure script tries to get the user's compiler to not warn about
1851 unused function parameters if the build is not including one or more of the
1852 ACL/xattrs/iconv features.
1854 - The configure script now has better checks for figuring out if the included
1855 popt code should be used or not.
1857 - Fixed two testsuite glitches: avoid a failure if someone's `cd` command
1858 outputs the current directory when cd-ing to a relative path, and made the
1859 itemized test query how rsync was built to determine if it should expect
1860 hard-linked symlinks or not.
1862 - Updated the testsuite to verify that various bug fixes remain fixed.
1864 - The RPM spec file was updated to have: (1) comments for how to use the
1865 rsync-patch tar file, and (2) an /etc/xinetd.d/rsync file.
1867 - Updated the build scripts to work with a revised FTP directory structure.

1871 # NEWS for rsync 3.0.0 (1 Mar 2008)
1873 ## Changes in this version:
1875 ### PROTOCOL NUMBER:
1877 - The protocol number was changed to 30.
1879 ### NOTABLE CHANGES IN BEHAVIOR:
1881 - The handling of implied directories when using `--relative` has changed to
1882 send them as directories (e.g. no implied dir is ever sent as a symlink).
1883 This avoids unexpected behavior and should not adversely affect most people.
1884 If you're one of those rare individuals who relied upon having an implied
1885 dir be duplicated as a symlink, you should specify the transfer of the
1886 symlink and the transfer of the referent directory as separate args. (See
1887 also `--keep-dirlinks` and `--no-implied-dirs`.) Also, exclude rules no
1888 longer have a partial effect on implied dirs.
1890 - Requesting a remote file-listing without specifying `-r` (`--recursive`) now
1891 sends the `-d` (`--dirs`) option to the remote rsync rather than sending
1892 `-r` along with an extra exclude of `/*/*`. If the remote rsync does not
1893 understand the `-d` option (i.e. it is 2.6.3 or older), you will need to
1894 either turn off `-d` (`--no-d`), or specify `-r --exclude='/*/*'` manually.
1896 - In `--dry-run` mode, the last line of the verbose summary text is output
1897 with a "(DRY RUN)" suffix to help remind you that no updates were made.
1898 Similarly, `--only-write-batch` outputs `(BATCH ONLY)`.
1900 - A writable rsync daemon with `use chroot` disabled now defaults to a
1901 symlink-munging behavior designed to make symlinks safer while also allowing
1902 absolute symlinks to be stored and retrieved. This also has the effect of
1903 making symlinks unusable while they're in the daemon's hierarchy. See the
1904 daemon's `munge symlinks` parameter for details.
1906 - Starting up an extra copy of an rsync daemon will not clobber the pidfile
1907 for the running daemon -- if the pidfile exists, the new daemon will exit
1908 with an error. This means that your wrapper script that starts the rsync
1909 daemon should be made to handle lock-breaking (if you want any automatic
1910 breaking of locks to be done).
1914 - A daemon with `use chroot = no` and excluded items listed in the daemon
1915 config file now properly checks an absolute-path arg specified for these
1916 options: `--compare-dest`, `--link-dest`, `--copy-dest`, `--partial-dir`,
1917 `--backup-dir`, `--temp-dir`, and `--files-from`.
1919 - A daemon can now be told to disable all user- and group-name translation on
1920 a per-module basis. This avoids a potential problem with a writable daemon
1921 module that has `use chroot` enabled -- if precautions weren't taken, a user
1922 could try to add a missing library and get rsync to use it. This makes rsync
1923 safer by default, and more configurable when id-translation is not desired.
1924 See the daemon's `numeric ids` parameter for full details.
1926 - A chroot daemon can now indicate which part of its path should affect the
1927 chroot call, and which part should become an inside-chroot path for the
1928 module. This allows you to have outside-the-transfer paths (such as for
1929 libraries) even when you enable chroot protection. The idiom used in the
1930 rsyncd.conf file is: `path = /chroot/dirs/./dirs/inside`
1932 - If a file's data arrived successfully on the receiving side but the rename
1933 of the temporary file to the destination file failed AND the
1934 `--remove-source-files` (or the deprecated `--remove-sent-files`) option was
1935 specified, rsync no longer erroneously removes the associated source file.
1937 - Fixed the output of `-ii` when combined with one of the `--*-dest` options:
1938 it now itemizes all the items, not just the changed ones.
1940 - Made the output of all file types consistent when using a `--*-dest` option.
1941 Prior versions would output too many creation events for matching items.
1943 - The code that waits for a child pid now handles being interrupted by a
1944 signal. This fixes a problem with the pre-xfer exec function not being able
1945 to get the exit status from the script.
1947 - A negated filter rule (i.e. with a '!' modifier) no longer loses the
1948 negation when sending the filter rules to the remote rsync.
1950 - Fixed a problem with the `--out-format` (aka `--log-format`) option %f: it
1951 no longer outputs superfluous directory info for a non-daemon rsync.
1953 - Fixed a problem with `-vv` (double `--verbose`) and `--stats` when `pushing`
1954 files (which includes local copies). Version 2.6.9 would complete the copy,
1955 but exit with an error when the receiver output its memory stats.
1957 - If `--password-file` is used on a non-daemon transfer, rsync now complains
1958 and exits. This should help users figure out that they can't use this option
1959 to control a remote shell's password prompt.
1961 - Make sure that directory permissions of a newly-created destination
1962 directory are handled right when `--perms` is left off.
1964 - The itemized output of a newly-created destination directory is now output
1965 as a creation event, not a change event.
1967 - Improved `--hard-link` so that more corner cases are handled correctly when
1968 combined with options such as `--link-dest` and/or `--ignore-existing`.
1970 - The `--append` option no longer updates a file that has the same size.
1972 - Fixed a bug when combining `--backup` and `--backup-dir` with `--inplace`:
1973 any missing backup directories are now created.
1975 - Fixed a bug when using `--backup` and `--inplace` with `--whole-file` or
1976 `--read-batch`: backup files are actually created now.
1978 - The daemon pidfile is checked and created sooner in the startup sequence.
1980 - If a daemon module's `path` value is not an absolute pathname, the code now
1981 makes it absolute internally (making it work properly).
1983 - Ensure that a temporary file always has owner-write permission while we are
1984 writing to it. This avoids problems with some network filesystems when
1985 transferring read-only files.
1987 - Any errors output about password-file reading no longer cause an error at
1988 the end of the run about a partial transfer.
1990 - The `--read-batch` option for protocol 30 now ensures that several more
1991 options are set correctly for the current batch file: `--iconv`, `--acls`,
1992 `--xattrs`, `--inplace`, `--append`, and `--append-verify`.
1994 - Using `--only-write-batch` to a daemon receiver now works properly (older
1995 versions would update some files while writing the batch).
1997 - Avoid outputting a "file has vanished" message when the file is a broken
1998 symlink and `--copy-unsafe-links` or `--copy-dirlinks` is used (the code
1999 already handled this for `--copy-links`).
2001 - Fixed the combination of `--only-write-batch` and `--dry-run`.
2003 - Fixed rsync's ability to remove files that are not writable by the file's
2004 owner when rsync is running as the same user.
2006 - When transferring large files, the sender's hashtable of checksums is kept
2007 at a more reasonable state of fullness (no more than 80% full) so that the
2008 scanning of the hashtable will not bog down as the number of blocks
2013 - A new incremental-recursion algorithm is now used when rsync is talking to
2014 another 3.x version. This starts the transfer going more quickly (before all
2015 the files have been found), and requires much less memory. See the
2016 `--recursive` option in the manpage for some restrictions.
2018 - Lowered memory use in the non-incremental-recursion algorithm for typical
2019 option values (usually saving from 21-29 bytes per file).
2021 - The default `--delete` algorithm is now `--delete-during` when talking to a
2022 3.x rsync. This is a faster scan than using `--delete-before` (which is the
2023 default when talking to older rsync versions), and is compatible with the
2024 new incremental recursion mode.
2026 - Rsync now allows multiple remote-source args to be specified rather than
2027 having to rely on a special space-splitting side-effect of the remote-
2028 shell. Additional remote args must specify the same host or an empty one
2029 (e.g. empty: `:file1` or `::module/file2`). For example, this means that
2030 local use of brace expansion now works: `rsync -av host:dir/{f1,f2} .`
2032 - Added the `--protect-args` (`-s`) option, that tells rsync to send most of
2033 the command-line args at the start of the transfer rather than as args to
2034 the remote-shell command. This protects them from space-splitting, and only
2035 interprets basic wildcard special shell characters (`*?[`).
2037 - Added the `--delete-delay` option, which is a more efficient way to delete
2038 files at the end of the transfer without needing a separate delete pass.
2040 - Added the `--acls` (`-A`) option to preserve Access Control Lists. This is
2041 an improved version of the prior patch that was available, and it even
2042 supports OS X ACLs. If you need to have backward compatibility with old,
2043 ACL-patched versions of rsync, apply the acls.diff file from the patches
2046 - Added the `--xattrs` (`-X`) option to preserve extended attributes. This is
2047 an improved version of the prior patch that was available, and it even
2048 supports OS X xattrs (which includes their resource fork data). If you need
2049 to have backward compatibility with old, xattr-patched versions of rsync,
2050 apply the xattrs.diff file from the patches dir.
2052 - Added the `--fake-super` option that allows a non-super user to preserve all
2053 attributes of a file by using a special extended-attribute idiom. It even
2054 supports the storing of foreign ACL data on your backup server. There is
2055 also an analogous `fake super` parameter for an rsync daemon.
2057 - Added the `--iconv` option, which allows rsync to convert filenames from one
2058 character-set to another during the transfer. The default is to make this
2059 feature available as long as your system has `iconv_open()`. If compilation
2060 fails, specify `--disable-iconv` to configure, and then rebuild. If you want
2061 rsync to perform character-set conversions by default, you can specify
2062 `--enable-iconv=CONVERT_STRING` with the default value for the `--iconv`
2063 option that you wish to use. For example, `--enable-iconv=.` is a good
2064 choice. See the rsync manpage for an explanation of the `--iconv` option's
2067 - A new daemon config parameter, `charset`, lets you control the character-
2068 set that is used during an `--iconv` transfer to/from a daemon module. You
2069 can also set your daemon to refuse `no-iconv` if you want to force the
2070 client to use an `--iconv` transfer (requiring an rsync 3.x client).
2072 - Added the `--skip-compress=LIST` option to override the default list of file
2073 suffixes that will not be compressed when using `--compress` (`-z`).
2075 - The daemon's default for `dont compress` was extended to include: `*.7z`
2076 `*.mp[34]` `*.mov` `*.avi` `*.ogg` `*.jpg` `*.jpeg` and the name-matching routine was also
2077 optimized to run more quickly.
2079 - The `--max-delete` option now outputs a warning if it skipped any file
2080 deletions, including a count of how many deletions were skipped. (Older
2081 versions just silently stopped deleting things.)
2083 - You may specify `--max-delete=0` to a 3.0.0 client to request that it warn
2084 about extraneous files without deleting anything. If you're not sure what
2085 version the client is, you can use the less-obvious `--max-delete=-1`, as
2086 both old and new versions will treat that as the same request (though older
2087 versions don't warn).
2089 - The `--hard-link` option now uses less memory on both the sending and
2090 receiving side for all protocol versions. For protocol 30, the use of a
2091 hashtable on the sending side allows us to more efficiently convey to the
2092 receiver what files are linked together. This reduces the amount of data
2093 sent over the socket by a considerable margin (rather than adding more
2094 data), and limits the in-memory storage of the device+inode information to
2095 just the sending side for the new protocol 30, or to the receiving side when
2096 speaking an older protocol (note that older rsync versions kept the
2097 device+inode information on both sides).
2099 - The filter rules now support a perishable (`p`) modifier that marks rules
2100 that should not have an effect in a directory that is being deleted. e.g.
2101 `-f '-p .svn/'` would only affect `live` .svn directories.
2103 - Rsync checks all the alternate-destination args for validity (e.g.
2104 `--link-dest`). This lets the user know when they specified a directory that
2107 - If we get an ENOSYS error setting the time on a symlink, we don't complain
2108 about it anymore (for those systems that even support the setting of the
2109 modify-time on a symlink).
2111 - Protocol 30 now uses MD5 checksums instead of MD4.
2113 - Changed the `--append` option to not checksum the existing data in the
2114 destination file, which speeds up file appending.
2116 - Added the `--append-verify` option, which works like the older `--append`
2117 option (verifying the existing data in the destination file). For
2118 compatibility with older rsync versions, any use of `--append` that is
2119 talking protocol 29 or older will revert to the `--append-verify` method.
2121 - Added the `--contimeout=SECONDS` option that lets the user specify a
2122 connection timeout for rsync daemon access.
2124 - Documented and extended the support for the `RSYNC_CONNECT_PROG` variable
2125 that can be used to enhance the client side of a daemon connection.
2127 - Improved the dashes and double-quotes in the nroff manpage output.
2129 - Rsync now supports a lot more `--no-OPTION` override options.
2133 - The file-list sorting algorithm now uses a sort that keeps any same-named
2134 items in the same order as they were specified. This allows rsync to always
2135 ensure that the first of the duplicates is the one that will be included in
2136 the copy. The new sort is also faster than the glibc version of qsort() and
2139 - Rsync now supports the transfer of 64-bit timestamps (`time_t` values).
2141 - Made the file-deletion code use a little less stack when recursing through a
2142 directory hierarchy of extraneous files.
2144 - Fixed a build problem with older (2.x) versions of gcc.
2146 - Added some isType() functions that make dealing with signed characters
2147 easier without forcing variables via casts.
2149 - Changed strcat/strcpy/sprintf function calls to use safer versions.
2151 - Upgraded the included popt version to 1.10.2 and improved its use of
2152 string-handling functions.
2154 - Added missing prototypes for compatibility functions from the lib dir.
2156 - Configure determines if iconv() has a const arg, allowing us to avoid a
2159 - Made the sending of some numbers more efficient for protocol 30.
2161 - Make sure that a daemon process doesn't mind if the client was weird and
2162 omitted the `--server` option.
2164 - There are more internal logging categories available in protocol 30 than the
2165 age-old FINFO and FERROR, including `FERROR_XFER` and FWARN. These new
2166 categories allow some errors and warnings to go to stderr without causing an
2167 erroneous end-of-run warning about some files not being able to be
2170 - Improved the use of `const` on pointers.
2172 - Improved J.W.'s `pool_alloc` routines to add a way of incrementally freeing
2173 older sections of a pool's memory.
2175 - The getaddrinfo.c compatibility code in the `lib` dir was replaced with some
2176 new code (derived from samba, derived from PostgreSQL) that has a better
2177 license than the old code.
2179 ### DEVELOPER RELATED:
2181 - Rsync is now licensed under the GPLv3 or later.
2183 - Rsync is now being maintained in a `git` repository instead of CVS (though
2184 the old CVS repository still exists for historical access). Several
2185 maintenance scripts were updated to work with git.
2187 - Generated files are no longer committed into the source repository. The
2188 autoconf and autoheader commands are now automatically run during the normal
2189 use of `configure` and `make`. The latest dev versions of all generated
2190 files can also be copied from the samba.org web site (see the prepare-source
2191 script's fetch option).
2193 - The `patches` directory of diff files is now built from branches in the
2194 rsync git repository (branch patch/FOO creates file patches/FOO.diff). This
2195 directory is now distributed in a separate separate tar file named
2196 rsync-patches-VERSION.tar.gz instead of the main rsync-VERSION.tar.gz.
2198 - The proto.h file is now built using a simple perl script rather than a
2199 complex awk script, which proved to be more widely compatible.
2201 - When running the tests, we now put our per-test temp dirs into a sub-
2202 directory named testtmp (which is created, if missing). This allows someone
2203 to symlink the testtmp directory to another filesystem (which is useful if
2204 the build dir's filesystem does not support ACLs and xattrs, but another
2207 - Rsync now has a way of handling protocol-version changes during the
2208 development of a new protocol version. This causes any out-of-sync versions
2209 to speak an older protocol rather than fail in a cryptic manner. This
2210 addition makes it safer to deploy a pre-release version that may interact
2211 with the public. This new exchange of sub-version info does not interfere
2212 with the `{MIN,MAX}_PROTOCOL_VERSION` checking algorithm (which does not
2213 have enough range to allow the main protocol number to be incremented for
2214 every minor tweak in that happens during development).
2216 - The csprotocol.txt file was updated to mention the daemon protocol change in
2219 ------------------------------------------------------------------------------
2221 # NEWS for rsync 2.6.9 (6 Nov 2006)
2223 ## Changes in this version:
2227 - If rsync is interrupted via a handled signal (such as SIGINT), it will once
2228 again clean-up its temp file from the destination dir.
2230 - Fixed an overzealous sanitizing bug in the handling of the `--link-dest`,
2231 `--copy-dest`, and `--compare-dest` options to a daemon without chroot: if
2232 the copy's destination dir is deeper than the top of the module's path,
2233 these options now accept a safe number of parent-dir (../) references (since
2234 these options are relative to the destination dir). The old code incorrectly
2235 chopped off all `../` prefixes for these options, no matter how deep the
2236 destination directory was in the module's hierarchy.
2238 - Fixed a bug where a deferred info/error/log message could get sent directly
2239 to the sender instead of being handled by rwrite() in the generator. This
2240 fixes an `unexpected tag 3` fatal error, and should also fix a potential
2241 problem where a deferred info/error message from the receiver might bypass
2242 the log file and get sent only to the client process. (These problems could
2243 only affect an rsync daemon that was receiving files.)
2245 - Fixed a bug when `--inplace` was combined with a `--*-dest` option and we
2246 update a file's data using an alternate basis file. The code now notices
2247 that it needs to copy the matching data from the basis file instead of
2248 (wrongly) assuming that it was already present in the file.
2250 - Fixed a bug where using `--dry-run` with a `--*-dest` option with a path
2251 relative to a directory that does not yet exist: the affected option gets
2252 its proper path value so that the output of the dry-run is right.
2254 - Fixed a bug in the %f logfile escape when receiving files: the destination
2255 path is now included in the output (e.g. you can now tell when a user
2256 specifies a subdir inside a module).
2258 - If the receiving side fails to create a directory, it will now skip trying
2259 to update everything that is inside that directory.
2261 - If `--link-dest` is specified with `--checksum` but without `--times`, rsync
2262 will now allow a hard-link to be created to a matching link-dest file even
2263 when the file's modify-time doesn't match the server's file.
2265 - The daemon now calls more timezone-using functions prior to doing a chroot.
2266 This should help some C libraries to generate proper timestamps from inside
2267 a chrooted daemon (and to not try to access /etc/timezone over and over
2270 - Fixed a bug in the handling of an absolute `--partial-dir=ABS_PATH` option:
2271 it now deletes an alternate basis file from the partial-dir that was used to
2272 successfully update a destination file.
2274 - Fixed a bug in the handling of `--delete-excluded` when using a per-dir
2275 merge file: the merge file is now honored on the receiving side, and only
2276 its unqualified include/exclude commands are ignored (just as is done for
2277 global include/excludes).
2279 - Fixed a recent bug where `--delete` was not working when transferring from
2280 the root (/) of the filesystem with `--relative` enabled.
2282 - Fixed a recent bug where an `--exclude='*'` could affect the root (/) of the
2283 filesystem with `--relative` enabled.
2285 - When `--inplace` creates a file, it is now created with owner read/write
2286 permissions (0600) instead of no permissions at all. This avoids a problem
2287 continuing a transfer that was interrupted (since `--inplace` will not
2288 update a file that has no write permissions).
2290 - If either `--remove-source-files` or `--remove-sent-files` is enabled and we
2291 are unable to remove the source file, rsync now outputs an error.
2293 - Fixed a bug in the daemon's `incoming chmod` rule: newly-created directories
2294 no longer get the 'F' (file) rules applied to them.
2296 - Fixed an infinite loop bug when a filter rule was rejected due to being
2299 - When the server receives a `--partial-dir` option from the client, it no
2300 longer runs the client-side code that adds an assumed filter rule (since the
2301 client will be sending us the rules in the usual manner, and they may have
2302 chosen to override the auto-added rule).
2306 - Added the `--log-file=FILE` and `--log-file-format=FORMAT` options. These
2307 can be used to tell any rsync to output what it is doing to a log file.
2308 They work with a client rsync, a non-daemon server rsync (see the man page
2309 for instructions), and also allows the overriding of rsyncd.conf settings
2310 when starting a daemon.
2312 - The `--log-format` option was renamed to be `--out-format` to avoid
2313 confusing it with affecting the log-file output. (The old option remains as
2314 an alias for the new to preserve backward compatibility.)
2316 - Made `log file` and `syslog facility` settable on a per-module basis in the
2317 daemon's config file.
2319 - Added the `--remove-source-files` option as a replacement for the (now
2320 deprecated) `--remove-sent-files` option. This new option removes all
2321 non-dirs from the source directories, even if the file was already
2322 up-to-date. This fixes a problem where interrupting an rsync that was using
2323 `--remove-sent-files` and restarting it could leave behind a file that the
2324 earlier rsync synchronized, but didn't get to remove. (The deprecated
2325 `--remove-sent-files` is still understood for now, and still behaves in the
2326 same way as before.)
2328 - Added the option `--no-motd` to suppress the message-of-the-day output from
2329 a daemon when doing a copy. (See the manpage for a caveat.)
2331 - Added a new environment variable to the pre-/post-xfer exec commands (in the
2332 daemon's config file): `RSYNC_PID`. This value will be the same in both the
2333 pre- and post-xfer commands, so it can be used as a unique ID if the
2334 pre-xfer command wants to cache some arg/request info for the post-xfer
2339 - Did a code audit using IBM's code-checker program and made several changes,
2340 including: replacing most of the strcpy() and sprintf() calls with
2341 strlcpy(), snprintf(), and memcpy(), adding a 0-value to an enum that had
2342 been intermingling a literal 0 with the defined enum values, silencing some
2343 uninitialized memory checks, marking some functions with a `noreturn`
2344 attribute, and changing an `if` that could never succeed on some platforms
2345 into a pre-processor directive that conditionally compiles the code.
2347 - Fixed a potential bug in `f_name_cmp()` when both the args are a top-level
2348 `.` dir (which doesn't happen in normal operations).
2350 - Changed `exit_cleanup()` so that it can never return instead of exit. The
2351 old code might return if it found the `exit_cleanup()` function was being
2352 called recursively. The new code is segmented so that any recursive calls
2353 move on to the next step of the exit-processing.
2355 - The macro WIFEXITED(stat) will now be defined if the OS didn't already
2358 ### DEVELOPER RELATED:
2360 - The acls.diff and xattrs.diff patches have received a bunch of work to make
2361 them much closer to being acceptable in the main distribution. The xattrs
2362 patch also has some preliminary Mac OS X and FreeBSD compatibility code that
2363 various system types to exchange extended file-attributes.
2365 - A new diff in the patches dir, fake-root.diff, allows rsync to maintain a
2366 backup hierarchy with full owner, group, and device info without actually
2367 running as root. It does this using a special extended attribute, so it
2368 depends on xattrs.diff (which depends on acls.diff).
2370 - The rsync.yo and rsyncd.conf.yo files have been updated to work better with
2371 the latest yodl 2.x releases.
2373 - Updated config.guess and config.sub to their 2006-07-02 versions.
2375 - Updated various files to include the latest FSF address and to have
2376 consistent opening comments.
2378 ------------------------------------------------------------------------------
2380 # NEWS for rsync 2.6.8 (22 Apr 2006)
2382 ## Changes in this version:
2386 - Fixed a bug in the exclude code where an anchored exclude without any
2387 wildcards fails to match an absolute source arg, but only when `--relative`
2390 - Improved the I/O code for the generator to fix a potential hang when the
2391 receiver gets an EOF on the socket but the generator's select() call never
2392 indicates that the socket is writable for it to be notified about the EOF.
2393 (This can happen when using stunnel).
2395 - Fixed a problem with the file-reading code where a failed read (such as that
2396 caused by a bad sector) would not advance the file's read-position beyond
2397 the failed read's data.
2399 - Fixed a logging bug where the `log file` directive was not being honored in
2400 a single-use daemon (one spawned by a remote-shell connection or by init).
2402 - If rsync cannot honor the `--delete` option, we output an error and exit
2403 instead of silently ignoring the option.
2405 - Fixed a bug in the `--link-dest` code that prevented special files (such as
2406 fifos) from being linked.
2408 - The ability to hard-link symlinks and special files is now determined at
2409 configure time instead of at runtime. This fixes a bug with `--link-dest`
2410 creating a hard-link to a symlink's referent on a BSD system.
2414 - In daemon mode, if rsync fails to bind to the requested port, the error(s)
2415 returned by socket() and/or bind() are now logged.
2417 - When we output a fatal error, we now output the version of rsync in the
2420 - Improved the documentation for the `--owner` and `--group` options.
2422 - The rsyncstats script in `support` has an improved line-parsing regex that
2423 is easier to read and also makes it to parse syslog-generated lines.
2425 - A new script in `support`: file-attr-restore, can be used to restore the
2426 attributes of a file-set (the permissions, ownership, and group info) taken
2427 from the cached output of a `find ARG... -ls` command.
2429 ### DEVELOPER RELATED:
2431 - Removed the unused function `write_int_named()`, the unused variable
2432 `io_read_phase`, and the rarely used variable `io_write_phase`. This also
2433 elides the confusing 'phase "unknown"' part of one error message.
2435 - Removed two unused configure checks and two related (also unused)
2436 compatibility functions.
2438 - The xattrs.diff patch received a security fix that prevents a potential
2439 buffer overflow in the `receive_xattr()` code.
2441 - The acls.diff patch has been improved quite a bit, with more to come.
2443 - A new patch was added: log-file.diff. This contains an early version of a
2444 future option, `--log-file=FILE`, that will allow any rsync to log its
2445 actions to a file (something that only a daemon supports at present).

2449 # NEWS for rsync 2.6.7 (11 Mar 2006)
2451 ## Changes in this version:
2455 - The letter 'D' in the itemized output was being used for both devices
2456 (character or block) as well as other special files (such as fifos and named
2457 sockets). This has changed to separate non-device special files under the
2458 'S' designation (e.g. `cS+++++++ path/fifo`). See also the `--specials`
2461 - The way rsync escapes unreadable characters has changed. First, rsync now
2462 has support for recognizing valid multi-byte character sequences in your
2463 current locale, allowing it to escape fewer characters than before for a
2464 locale such as UTF-8. Second, it now uses an escape idiom of `\#123`, which
2465 is the literal string `\#` followed by exactly 3 octal digits. Rsync no
2466 longer doubles a backslash character in a filename (e.g. it used to output
2467 `foo\\bar` when copying `foo\bar`) -- now it only escapes a backslash that
2468 is followed by a hash-sign and 3 digits (0-9) (e.g. it will output
2469 `foo\#134#789` when copying `foo\#789`). See also the `--8-bit-output`
2470 (`-8`) option, mentioned below.
2472 Script writers: the local rsync is the one that outputs escaped names, so if
2473 you need to support unescaping of filenames for older rsyncs, I'd suggest
2474 that you parse the output of `rsync --version` and only use the old
2475 unescaping rules for 2.6.5 and 2.6.6.
2479 - Fixed a really old bug that caused `--checksum` (`-c`) to checksum all the
2480 files encountered during the delete scan (ouch).
2482 - Fixed a potential hang in a remote generator: when the receiver gets a
2483 read-error on the socket, it now signals the generator about this so that
2484 the generator does not try to send any of the terminating error messages to
2485 the client (avoiding a potential hang in some setups).
2487 - Made hard-links work with symlinks and devices again.
2489 - If the sender gets an early EOF reading a source file, we propagate this
2490 error to the receiver so that it can discard the file and try requesting it
2491 again (which is the existing behavior for other kinds of read errors).
2493 - If a device-file/special-file changes permissions, rsync now updates the
2494 permissions without recreating the file.
2496 - If the user specifies a remote-host for both the source and destination, we
2497 now output a syntax error rather than trying to open the destination
2498 hostspec as a filename.
2500 - When `--inplace` creates a new destination file, rsync now creates it with
2501 permissions 0600 instead of 0000 -- this makes restarting possible when the
2502 transfer gets interrupted in the middle of sending a new file.
2504 - Reject the combination of `--inplace` and `--sparse` since the sparse-output
2505 algorithm doesn't work when overwriting existing data.
2507 - Fixed the directory name in the error that is output when `pop_dir()` fails.
2509 - Really fixed the parsing of a `!` entry in .cvsignore files this time.
2511 - If the generator gets a stat() error on a file, output it (this used to
2512 require at least `-vv` for the error to be seen).
2514 - If waitpid() fails or the child rsync didn't exit cleanly, we now handle the
2515 exit status properly and generate a better error.
2517 - Fixed some glitches in the double-verbose output when using `--copy-dest`,
2518 `--link-dest`, or `--compare-dest`. Also improved how the verbose output
2519 handles hard-links (within the transfer) that had an up-to-date alternate
2520 `dest` file, and copied files (via `--copy-dest`).
2522 - Fixed the matching of the dont-compress items (e.g. `*.gz`) against files
2523 that have a path component containing a slash.
2525 - If the code reading a filter/exclude file gets an EINTR error, rsync now
2526 clears the error flag on the file handle so it can keep on reading.
2528 - If `--relative` is active, the sending side cleans up trailing `/` or `/.`
2529 suffixes to avoid triggering a bug in older rsync versions. Also, we now
2530 reject a `..` dir if it would be sent as a relative dir.
2532 - If a non-directory is in the way of a directory and rsync is run with
2533 `--dry-run` and `--delete`, rsync no longer complains about not being able
2534 to opendir() the not-yet present directory.
2536 - When `--list-only` is used and a non-existent local destination dir was also
2537 specified as a destination, rsync no longer generates a warning about being
2538 unable to create the missing directory.
2540 - Fixed some problems with `--relative --no-implied-dirs` when the destination
2541 directory did not yet exist: we can now create a symlink or device when it
2542 is the first thing in the missing dir, and `--fuzzy` no longer complains
2543 about being unable to open the missing dir.
2545 - Fixed a bug where the `--copy-links` option would not affect implied
2546 directories without `--copy-unsafe-links` (see `--relative`).
2548 - Got rid of the need for `--force` to be used in some circumstances with
2549 `--delete-after` (making it consistent with
2550 `--delete-before`/`--delete-during`).
2552 - Rsync now ignores the SIGXFSZ signal, just in case your OS sends this when a
2553 file is too large (rsync handles the write error).
2555 - Fixed a bug in the Proxy-Authorization header's base64-encoded value: it was
2556 not properly padded with trailing '=' chars. This only affects a user that
2557 need to use a password-authenticated proxy for an outgoing daemon-rsync
2560 - If we're transferring an empty directory to a new name, rsync no longer
2561 forces `S_IWUSR` if it wasn't already set, nor does it accidentally leave it
2564 - Fixed a bug in the debug output (`-vvvvv`) that could mention the wrong
2565 checksum for the current file offset.
2567 - Rsync no longer allows a single directory to be copied over a non-directory
2572 - Added the `--append` option that makes rsync append data onto files that are
2573 longer on the source than the destination (this includes new files).
2575 - Added the `--min-size=SIZE` option to exclude small files from the transfer.
2577 - Added the `--compress-level` option to allow you to set how aggressive
2578 rsync's compression should be (this option implies `--compress`).
2580 - Enhanced the parsing of the SIZE value for `--min-size` and `--max-size` to
2581 allow easy entry of multiples of 1000 (instead of just multiples of 1024)
2582 and off-by-one values too (e.g. `--max-size=8mb-1`).
2584 - Added the `--8-bit-output` (`-8`) option, which tells rsync to avoid
2585 escaping high-bit characters that it thinks are unreadable in the current
2588 - The new option `--human-readable` (`-h`) changes the output of `--progress`,
2589 `--stats`, and the end-of-run summary to be easier to read. If repeated, the
2590 units become powers of 1024 instead of powers of 1000. (The old meaning of
2591 `-h`, as a shorthand for `--help`, still works as long as you just use it on
2592 its own, as in `rsync -h`.)
2594 - If lutimes() and/or lchmod() are around, use them to allow the preservation
2595 of attributes on symlinks.
2597 - The `--link-dest` option now affects symlinks and devices (when possible).
2599 - Added two config items to the rsyncd.conf parsing: `pre-xfer exec` and
2600 `post-xfer exec`. These allow a command to be specified on a per-module
2601 basis that will be run before and/or after a daemon-mode transfer. (See the
2602 man page for a list of the environment variables that are set with
2603 information about the transfer.)
2605 - When using the `--relative` option, you can now insert a dot dir in the
2606 source path to indicate where the replication of the source dirs should
2607 start. For example, if you specify a source path of
2608 rsync://host/module/foo/bar/./baz/dir with `-R`, rsync will now only
2609 replicate the `baz/dir` part of the source path (note: a trailing dot dir is
2610 unaffected unless it also has a trailing slash).
2612 - Added some new `--no-FOO` options that make it easier to override unwanted
2613 implied or default options. For example, `-a --no-o` (aka `--archive
2614 --no-owner`) can be used to turn off the preservation of file ownership that
2617 - Added the `--chmod=MODE` option that allows the destination permissions to
2618 be changed from the source permissions. E.g. `--chmod=g+w,o-rwx`
2620 - Added the `incoming chmod` and `outgoing chmod` daemon options that allow a
2621 module to specify what permissions changes should be applied to all files
2622 copied to and from the daemon.
2624 - Allow the `--temp-dir` option to be specified when starting a daemon, which
2625 sets the default temporary directory for incoming files.
2627 - If `--delete` is combined with `--dirs` without `--recursive`, rsync will
2628 now delete in any directory whose content is being synchronized.
2630 - If `--backup` is combined with `--delete` without `--backup-dir` (and
2631 without `--delete-excluded`), we add a `protect` filter-rule to ensure that
2632 files with the backup suffix are not deleted.
2634 - The file-count stats that are output by `--progress` were improved to better
2635 indicate what the numbers mean. For instance, the output: `(xfer#5,
2636 to-check=8383/9999)` indicates that this was the fifth file to be
2637 transferred, and we still need to check 8383 more files out of a total of
2640 - The include/exclude code now allows a `dir/***` directive (with 3 trailing
2641 stars) to match both the dir itself as well as all the content below the dir
2642 (`dir/**` would not match the dir).
2644 - Added the `--prune-empty-dirs` (`-m`) option that makes the receiving rsync
2645 discard empty chains of directories from the file-list. This makes it easier
2646 to selectively copy files from a source hierarchy and end up with just the
2647 directories needed to hold the resulting files.
2649 - If the `--itemize-changes` (`-i`) option is repeated, rsync now includes
2650 unchanged files in the itemized output (similar to `-vv`, but without all
2651 the other verbose messages that can get in the way). Of course, the client
2652 must be version 2.6.7 for this to work, but the remote rsync only needs to
2653 be 2.6.7 if you're pushing files.
2655 - Added the `--specials` option to tell rsync to copy non-device special files
2656 (which rsync now attempts even as a normal user). The `--devices` option now
2657 requests the copying of just devices (character and block). The `-D` option
2658 still requests both (e.g. `--devices` and `--specials`), `-a` still implies
2659 `-D`, and non-root users still get a silent downgrade that omits device
2662 - Added the `--super` option to make the receiver always attempt super-user
2663 activities. This is useful for systems that allow things such as devices to
2664 be created or ownership to be set without being UID 0, and is also useful
2665 for someone who wants to ensure that errors will be output if the receiving
2666 rsync isn't being run as root.
2668 - Added the `--sockopts` option for those few who want to customize the TCP
2669 options used to contact a daemon rsync.
2671 - Added a way for the `--temp-dir` option to be combined with a partial-dir
2672 setting that lets rsync avoid non-atomic updates (for those times when
2673 `--temp-dir` is not being used because space is tight).
2675 - A new support script, files-to-excludes, will transform a list of files into
2676 a set of include/exclude directives that will copy those files.
2678 - A new option, `--executability` (`-E`) can be used to preserve just the
2679 execute bit on files, for those times when using the `--perms` option is not
2682 - The daemon now logs each connection and also each module-list request that
2685 - New log-format options: %M (modtime), %U (uid), %G (gid), and %B (permission
2686 bits, e.g. `rwxr-xrwt`).
2688 - The `--dry-run` option no longer forces the enabling of `--verbose`.
2690 - The `--remove-sent-files` option now does a better job of incrementally
2691 removing the sent files on the sending side (older versions tended to clump
2692 up all the removals at the end).
2694 - A daemon now supersedes its minimal SIGCHLD handler with the standard
2695 PID-remembering version after forking. This ensures that the generator can
2696 get the child-exit status from the receiver.
2698 - Use of the `--bwlimit` option no longer interferes with the remote rsync
2699 sending error messages about invalid/refused options.
2701 - Rsync no longer returns a usage error when used with one local source arg
2702 and no destination: this now implies the `--list-only` option, just like the
2703 comparable situation with a remote source arg.
2705 - Added the `--copy-dirlinks` option, a more limited version of
2708 - Various documentation improvements, including: a better synopsis, some
2709 improved examples, a better discussion of the presence and absence of
2710 `--perms` (including how it interacts with the new `--executability` and
2711 `--chmod` options), an extended discussion of `--temp-dir`, an improved
2712 discussion of `--partial-dir`, a better description of rsync's pattern
2713 matching characters, an improved `--no-implied-dirs` section, and the
2714 documenting of what the `--stats` option outputs.
2716 - Various new and updated diffs in the patches dir, including: acls.diff,
2717 xattrs.diff, atimes.diff, detect-renamed.diff, and slp.diff.
2721 - We now use sigaction() and sigprocmask() if possible, and fall back on
2722 signal() if not. Using sigprocmask() ensures that rsync enables all the
2723 signals that it needs, just in case it was started in a masked state.
2725 - Some buffer sizes were expanded a bit, particularly on systems where
2726 MAXPATHLEN is overly small (e.g. Cygwin).
2728 - If `io_printf()` tries to format more data than fits in the buffer, exit
2729 with an error instead of transmitting a truncated buffer.
2731 - If a `va_copy` macro is defined, lib/snprintf.c will use it when defining
2732 the `VA_COPY` macro.
2734 - Reduced the amount of stack memory needed for each level of directory
2735 recursion by nearly MAXPATHLEN bytes.
2737 - The wildmatch function was extended to allow an array of strings to be
2738 supplied as the string to match. This allows the exclude code to do less
2741 - Got rid of the `safe_fname()` function (and all the myriad calls) and
2742 replaced it with a new function in the log.c code that filters all the
2743 output going to the terminal.
2745 - Unified the `f_name()` and the `f_name_to()` functions.
2747 - Improved the hash-table code the sender uses to handle checksums to make it
2748 use slightly less memory and run just a little faster.
2750 ### DEVELOPER RELATED:
2752 - The diffs in the patches dir now require `patch -p1 <DIFF` instead of the
2753 previous `-p0`. Also, the version included in the release tar now affect
2754 generated files (e.g. configure, rsync.1, proto.h, etc.), so it is no longer
2755 necessary to run autoconf and/or yodl unless you're applying a patch that
2756 was checked out from CVS.
2758 - Several diffs in the patches dir now use the proper `--enable-FOO` configure
2759 option instead of `--with-FOO` to turn on the inclusion of the newly patched
2762 - There is a new script, `prepare-source` than can be used to update the
2763 various generated files (proto.h, configure, etc.) even before configure has
2764 created the Makefile (this is mainly useful when patching the source with a
2765 patch that doesn't affect generated files).
2767 - The testsuite now sets HOME so that it won't be affected by a file such as
2770 ------------------------------------------------------------------------------
2772 # NEWS for rsync 2.6.6 (28 Jul 2005)
2774 ## Changes in this version:
2778 - The zlib code was upgraded to version 1.2.3 in order to make it more secure.
2779 While the widely-publicized security problem in zlib 1.2.2 did not affect
2780 rsync, another security problem surfaced that affects rsync's zlib 1.1.4.
2784 - The setting of `flist->high` in `clean_flist()` was wrong for an empty list.
2785 This could cause `flist_find()` to crash in certain rare circumstances (e.g.
2786 if just the right directory setup was around when `--fuzzy` was combined
2787 with `--link-dest`).
2789 - The outputting of hard-linked files when verbosity was > 1 was not right:
2790 (1) Without `-i` it would output the name of each hard-linked file as though
2791 it had been changed; it now outputs a `is hard linked` message for the file.
2792 (2) With `-i` it would output all dots for the unchanged attributes of a
2793 hard-link; it now changes those dots to spaces, as is done for other totally
2796 - When backing up a changed symlink or device, get rid of any old backup item
2797 so that we don't get an `already exists` error.
2799 - A couple places that were comparing a local and a remote modification-time
2800 were not honoring the `--modify-window` option.
2802 - Fixed a bug where the 'p' (permissions) itemized-changes flag might get set
2803 too often (if some non-significant mode bits differed).
2805 - Fixed a really old, minor bug that could cause rsync to warn about being
2806 unable to mkdir() a path that ends in `/.` because it just created the
2807 directory (required `--relative`, `--no-implied-dirs`, a source path that
2808 ended in either a trailing slash or a trailing `/.`, and a non-existing
2809 destination dir to tickle the bug in a recent version).
2813 - Made the `max verbosity` setting in the rsyncd.conf file settable on a
2814 per-module basis (which now matches the documentation).
2816 - The rrsync script has been upgraded to verify the args of options that take
2817 args (instead of rejecting any such options). It was also changed to try to
2818 be more secure and to fix a problem in the parsing of a pull operation that
2819 has multiple source args. (See the support dir.)
2821 - Improved the documentation that explains the difference between a normal
2822 daemon transfer and a daemon-over remote-shell transfer.
2824 - Some of the diffs supplied in the patches dir were fixed and/or improved.
2828 - Made configure define `NOBODY_USER` (currently hard-wired to `nobody`) and
2829 `NOBODY_GROUP` (set to either `nobody` or `nogroup` depending on what we
2830 find in the /etc/group file).
2832 - Added a test to the test suite, itemized.test, that tests the output of `-i`
2833 (log-format w/%i) and some double-verbose messages.
2835 ------------------------------------------------------------------------------
2837 # NEWS for rsync 2.6.5 (1 Jun 2005)
2839 ## Changes in this version:
2843 - Non-printable chars in filenames are now output using backslash-escaped
2844 characters rather than '?'s. Any non-printable character is output using 3
2845 digits of octal (e.g. `\n` -> `\012`), and a backslash is now output as
2846 `\\`. Rsync also uses your locale setting, which can make it treat fewer
2847 high-bit characters as non-printable.
2849 - If rsync received an empty file-list when pulling files, it would output a
2850 `nothing to do` message and exit with a 0 (success) exit status, even if the
2851 remote rsync returned an error (it did not do this under the same conditions
2852 when pushing files). This was changed to make the pulling behavior the same
2853 as the pushing behavior: we now do the normal end-of-run outputting
2854 (depending on options) and exit with the appropriate exit status.
2858 - A crash bug was fixed when a daemon had its `path` set to `/`, did not have
2859 chroot enabled, and used some anchored excludes in the rsyncd.conf file.
2861 - Fixed a bug in the transfer of a single file when `-H` is specified (rsync
2862 would either infinite loop or perhaps crash).
2864 - Fixed a case where the generator might try (and fail) to tweak the
2865 write-permissions of a read-only directory in list-only mode (this only
2866 caused an annoying warning message).
2868 - If `--compare-dest` or `--link-dest` uses a locally-copied file as the basis
2869 for an updated version, log this better when `--verbose` or `-i` is in
2872 - Fixed the accidental disabling of `--backup` during the `--delete-after`
2875 - Restored the ability to use the `--address` option in client mode (in
2876 addition to its use in daemon mode).
2878 - Make sure that some temporary progress information from the delete
2879 processing does not get left on the screen when it is followed by a newline.
2881 - When `--existing` skips a directory with extra verbosity, refer to it as a
2882 `directory`, not a `file`.
2884 - When transferring a single file to a different-named file, any generator
2885 messages that are source-file related no longer refer to the file by the
2886 destination filename.
2888 - Fixed a bug where hard-linking a group of files might fail if the generator
2889 hasn't created a needed destination directory yet.
2891 - Fixed a bug where a hard-linked group of files that is newly-linked to a
2892 file in a `--link-dest` dir doesn't link the files from the rest of the
2895 - When deleting files with the `--one-file-system` (`-x`) option set, rsync no
2896 longer tries to remove files from inside a mount-point on the receiving
2897 side. Also, we don't complain about being unable to remove the mount-point
2900 - Fixed a compatibility problem when using `--cvs-ignore` (`-C`) and sending
2901 files to an older rsync without using `--delete`.
2903 - Make sure that a `- !` or `+ !` include/exclude pattern does not trigger the
2904 list-clearing action that is reserved for `!`.
2906 - Avoid a timeout in the generator when the sender/receiver aren't handling
2907 the generator's checksum output quickly enough.
2909 - Fixed the omission of some directories in the delete processing when
2910 `--relative` (`-R`) was combined with a source path that had a trailing
2913 - Fixed a case where rsync would erroneously delete some files and then
2914 re-transfer them when the options `--relative` (`-R`) and `--recursive`
2915 (`-r`) were both enabled (along with `--delete`) and a source path had a
2918 - Make sure that `--max-size` doesn't affect a device or a symlink.
2920 - Make sure that a system with a really small MAXPATHLEN does not cause the
2921 buffers in `readfd_unbuffered()` to be too small to receive normal messages.
2922 (This mainly affected Cygwin.)
2924 - If a source pathname ends with a filename of `..`, treat it as if `../` had
2925 been specified (so that we don't copy files to the parent dir of the
2928 - If `--delete` is combined with a file-listing rsync command (i.e. no
2929 transfer is happening), avoid outputting a warning that we couldn't delete
2932 - If `--stats` is specified with `--delete-after`, ensure that all the
2933 `deleting` messages are output before the statistics.
2935 - Improved one `if` in the deletion code that was only checking errno for
2936 ENOTEMPTY when it should have also been checking for EEXIST (for
2937 compatibility with OS variations).
2941 - Added the `--only-write-batch=FILE` option that may be used (instead of
2942 `--write-batch=FILE`) to create a batch file without doing any actual
2943 updating of the destination. This allows you to divert all the file-updating
2944 data away from a slow data link (as long as you are pushing the data to the
2945 remote server when creating the batch).
2947 - When the generator is taking a long time to fill up its output buffer (e.g.
2948 if the transferred files are few, small, or missing), it now periodically
2949 flushes the output buffer so that the sender/receiver can get started on the
2950 files sooner rather than later.
2952 - Improved the keep-alive code to handle a long silence between the sender and
2953 the receiver that can occur when the sender is receiving the checksum data
2956 - Improved the auth-errors that are logged by the daemon to include some
2957 information on why the authorization failed: wrong user, password mismatch,
2958 etc. (The client-visible message is unchanged!)
2960 - Improved the client's handling of an `@ERROR` from a daemon so that it does
2961 not complain about an unexpectedly closed socket (since we really did expect
2962 the socket to close).
2964 - If the daemon can't open the log-file specified in rsyncd.conf, fall back to
2965 using syslog and log an appropriate warning. This is better than what was
2966 typically a totally silent (and fatal) failure (since a daemon is not
2967 usually run with the `--no-detach` option that was necessary to see the
2970 - The man pages now consistently refer to an rsync daemon as a `daemon`
2971 instead of a `server` (to distinguish it from the server process in a
2972 non-daemon transfer).
2974 - Made a small change to the rrsync script (restricted rsync -- in the support
2975 dir) to make a read-only server reject all `--remove-*` options when sending
2976 files (to future-proof it against the possibility of other similar options
2977 being added at some point).
2981 - Rsync now calls `setlocale(LC_CTYPE, "")`. This enables isprint() to better
2982 discern which filename characters need to be escaped in messages (which
2983 should result in fewer escaped characters in some locales).
2985 - Improved the naming of the log-file open/reopen/close functions.
2987 - Removed some protocol-compatibility code that was only needed to help
2988 someone running a pre-release of 2.6.4.
2992 - Added configure option `--disable-locale` to disable any use of setlocale()
2995 - Fixed a bug in the `SUPPORT{,_HARD}_LINKS` #defines which prevented rsync
2996 from being built without symlink or hard-link support.
2998 - Only #define `HAVE_REMSH` if it is going to be set to 1.
3000 - Configure now disables the use of mkstemp() under HP-UX (since they refuse
3001 to fix its broken handling of large files).
3003 - Configure now explicitly checks for the lseek64() function so that the code
3004 can use `HAVE_LSEEK64` instead of inferring lseek64()'s presence based on
3005 the presence of the `off64_t` type.
3007 - Configure no longer mentions the change in the default remote-shell (from
3008 rsh to ssh) that occurred for the 2.6.0 release.
3010 - Some minor enhancements to the test scripts.
3012 - Added a few new `*.diff` files to the patches dir, including a patch that
3013 enables the optional copying of extended attributes.

3017 # NEWS for rsync 2.6.4 (30 March 2005)
3019 ## Changes in this version:
3021 ### PROTOCOL NUMBER:
3023 - The protocol number was changed to 29.
3027 - When rsync deletes a directory and outputs a verbose message about it, it
3028 now appends a trailing slash to the name instead of (only sometimes)
3029 outputting a preceding "directory " string.
3031 - The `--stats` output will contain file-list time-statistics if both sides
3032 are 2.6.4, or if the local side is 2.6.4 and the files are being pushed
3033 (since the stats come from the sending side). (Requires protocol 29 for a
3036 - The `%o` (operation) log-format escape now has a third value (besides `send`
3037 and `recv`): `del.` (with trailing dot to make it 4 chars). This changes
3038 the way deletions are logged in the daemon's log file.
3040 - When the `--log-format` option is combined with `--verbose`, rsync now
3041 avoids outputting the name of the file twice in most circumstances. As long
3042 as the `--log-format` item does not refer to any post-transfer items (such
3043 as %b or %c), the `--log-format` message is output prior to the transfer, so
3044 `--verbose` is now the equivalent of a `--log-format` of '%n%L' (which
3045 outputs the name and any link info). If the log output must occur after the
3046 transfer to be complete, the only time the name is also output prior to the
3047 transfer is when `--progress` was specified (so that the name will precede
3048 the progress stats, and the full `--log-format` output will come after).
3050 - Non-printable characters in filenames are replaced with a '?' to avoid
3051 corrupting the screen or generating empty lines in the output.
3055 - Restore the list-clearing behavior of `!` in a .cvsignore file (2.6.3 was
3056 only treating it as a special token in an rsync include/exclude file).
3058 - The combination of `--verbose` and `--dry-run` now mentions the full list of
3059 changes that would be output without `--dry-run`.
3061 - Avoid a mkdir warning when removing a directory in the destination that
3062 already exists in the `--backup-dir`.
3064 - An OS that has a binary mode for its files (such as Cygwin) needed
3065 `setmode(fd, O_BINARY)` called on the temp-file we opened with mkstemp().
3066 (Fix derived from Cygwin's 2.6.3 rsync package.)
3068 - Fixed a potential hang when verbosity is high, the client side is the
3069 sender, and the file-list is large.
3071 - Fixed a potential protocol-corrupting bug where the generator could merge a
3072 message from the receiver into the middle of a multiplexed packet of data if
3073 only part of that data had been written out to the socket when the message
3074 from the generator arrived.
3076 - We now check if the OS doesn't support using mknod() for creating FIFOs and
3077 sockets, and compile-in some compatibility code using mkfifo() and socket()
3080 - Fixed an off-by-one error in the handling of `--max-delete=N`. Also, if the
3081 `--max-delete` limit is exceeded during a run, we now output a warning about
3082 this at the end of the run and exit with a new error code (25).
3084 - One place in the code wasn't checking if fork() failed.
3086 - The `ignore nonreadable` daemon parameter used to erroneously affect
3087 readable symlinks that pointed to a non-existent file.
3089 - If the OS does not have lchown() and a chown() of a symlink will affect the
3090 referent of a symlink (as it should), we no longer try to set the user and
3093 - The generator now properly runs the hard-link loop and the dir-time
3094 rewriting loop after we're sure that the redo phase is complete.
3096 - When `--backup` was specified with `--partial-dir=DIR`, where DIR is a
3097 relative path, the backup code was erroneously trying to backup a file that
3098 was put into the partial-dir.
3100 - If a file gets resent in a single transfer and the `--backup` option is
3101 enabled along with `--inplace`, rsync no longer performs a duplicate backup
3102 (it used to overwrite the first backup with the failed file).
3104 - One call to `flush_write_file()` was not being checked for an error.
3106 - The `--no-relative` option was not being sent from the client to a server
3109 - If an rsync daemon specified `dont compress = ...` for a file and the client
3110 tried to specify `--compress`, the libz code was not handling a compression
3111 level of 0 properly. This could cause a transfer failure if the block-size
3112 for a file was large enough (e.g. rsync might have exited with an error for
3115 - Fixed a bug that would sometimes surface when using `--compress` and sending
3116 a file with a block-size larger than 64K (either manually specified, or
3117 computed due to the file being really large). Prior versions of rsync would
3118 sometimes fail to decompress the data properly, and thus the transferred
3119 file would fail its verification.
3121 - If a daemon can't open the specified log file (i.e. syslog is not being
3122 used), die without crashing. We also output an error about the failure on
3123 stderr (which will only be seen if `--no-detach` was specified) and exit
3124 with a new error code (6).
3126 - A local transfer no longer duplicates all its include/exclude options (since
3127 the forked process already has a copy of the exclude list, there's no need
3128 to send them a set of duplicates).
3130 - The output of the items that are being updated by the generator (dirs,
3131 symlinks, devices) is now intermingled in the proper order with the output
3132 from the items that the receiver is updating (regular files) when pulling.
3133 This misordering was particularly bad when `--progress` was specified.
3134 (Requires protocol 29.)
3136 - When `--timeout` is specified, lulls that occur in the transfer while the
3137 generator is doing work that does not generate socket traffic (looking for
3138 changed files, deleting files, doing directory-time touch-ups, etc.) will
3139 cause a new keep-alive packet to be sent that should keep the transfer going
3140 as long as the generator continues to make progress. (Requires protocol 29.)
3142 - The stat size of a device is not added to the total file size of the items
3143 in the transfer (the size might be undefined on some OSes).
3145 - Fixed a problem with refused-option messages sometimes not making it back to
3146 the client side when a remote `--files-from` was in effect and the daemon
3149 - The `--compare-dest` option was not updating a file that differed in (the
3150 preserved) attributes from the version in the compare-dest DIR.
3152 - When rsync is copying files into a write-protected directory, fixed the
3153 change-report output for the directory so that we don't report an identical
3154 directory as changed.
3158 - Rsync now supports popt's option aliases, which means that you can use
3159 /etc/popt and/or ~/.popt to create your own option aliases.
3161 - Added the `--delete-during` (`--del`) option which will delete files from
3162 the receiving side incrementally as each directory in the transfer is being
3163 processed. This makes it more efficient than the default,
3164 before-the-transfer behavior, which is now also available as
3165 `--delete-before` (and is still the default `--delete-WHEN` option that will
3166 be chosen if `--delete` or `--delete-excluded` is specified without a
3167 `--delete-WHEN` choice). All the `--del*` options infer `--delete`, so an
3168 rsync daemon that refuses `delete` will still refuse to allow any
3169 file-deleting options (including the new `--remove-sent-files` option).
3171 - All the `--delete-WHEN` options are now more memory efficient: Previously an
3172 duplicate set of file-list objects was created on the receiving side for the
3173 entire destination hierarchy. The new algorithm only creates one directory
3174 of objects at a time (for files inside the transfer).
3176 - Added the `--copy-dest` option, which works like `--link-dest` except that
3177 it locally copies identical files instead of hard-linking them.
3179 - Added support for specifying multiple `--compare-dest`, `--copy-dest`, or
3180 `--link-dest` options, but only of a single type. (Promoted from the patches
3181 dir and enhanced.) (Requires protocol 29.)
3183 - Added the `--max-size` option. (Promoted from the patches dir.)
3185 - The daemon-mode options are now separated from the normal rsync options so
3186 that they can't be mixed together. This makes it impossible to start a
3187 daemon that has improper default option values (which could cause problems
3188 when a client connects, such as hanging or crashing).
3190 - The `--bwlimit` option may now be used in combination with `--daemon` to
3191 specify both a default value for the daemon side and a value that cannot be
3192 exceeded by a user-specified `--bwlimit` option.
3194 - Added the `port` parameter to the rsyncd.conf file. (Promoted from the
3195 patches dir.) Also added `address`. The command-line options take precedence
3196 over a config-file option, as expected.
3198 - In `_exit_cleanup()`: when we are exiting with a partially-received file, we
3199 now flush any data in the write-cache before closing the partial file.
3201 - The `--inplace` support was enhanced to work with `--compare-dest`,
3202 `--link-dest`, and (the new) `--copy-dest` options. (Requires protocol 29.)
3204 - Added the `--dirs` (`-d`) option for an easier way to copy directories
3205 without recursion. Any directories that are encountered are created on the
3206 destination. Specifying a directory with a trailing slash copies its
3207 immediate contents to the destination.
3209 - The `--files-from` option now implies `--dirs` (`-d`).
3211 - Added the `--list-only` option, which is mainly a way for the client to put
3212 the server into listing mode without needing to resort to any internal
3213 option kluges (e.g. the age-old use of `-r --exclude='/*/*'` for a
3214 non-recursive listing). This option is used automatically (behind the
3215 scenes) when a modern rsync speaks to a modern daemon, but may also be
3216 specified manually if you want to force the use of the `--list-only` option
3217 over a remote-shell connection.
3219 - Added the `--omit-dir-times` (`-O`) option, which will avoid updating the
3220 modified time for directories when `--times` was specified. This option will
3221 avoid an extra pass through the file-list at the end of the transfer (to
3222 tweak all the directory times), which may provide an appreciable speedup for
3223 a really large transfer. (Promoted from the patches dir.)
3225 - Added the `--filter` (`-f`) option and its helper option, `-F`. Filter rules
3226 are an extension to the existing include/exclude handling that also supports
3227 nested filter files as well as per-directory filter files (like .cvsignore,
3228 but with full filter-rule parsing). This new option was chosen in order to
3229 ensure that all existing include/exclude processing remained 100% compatible
3230 with older versions. Protocol 29 is needed for full filter-rule support, but
3231 backward-compatible rules work with earlier protocol versions. (Promoted
3232 from the patches dir and enhanced.)
3234 - Added the `--delay-updates` option that puts all updated files into a
3235 temporary directory (by default `.~tmp~`, but settable via the
3236 `--partial-dir=DIR` option) until the end of the transfer. This makes the
3237 updates a little more atomic for a large transfer.
3239 - If rsync is put into the background, any output from `--progress` is
3242 - Documented the `max verbosity` setting for rsyncd.conf. (This setting was
3243 added a couple releases ago, but left undocumented.)
3245 - The sender and the generator now double-check the file-list index they are
3246 given, and refuse to try to do a file transfer on a non-file index (since
3247 that would indicate that something had gone very wrong).
3249 - Added the `--itemize-changes` (`-i`) option, which is a way to output a more
3250 detailed list of what files changed and in what way. The effect is the same
3251 as specifying a `--log-format` of `%i %n%L` (see both the rsync and
3252 rsyncd.conf manpages). Works with `--dry-run` too.
3254 - Added the `--fuzzy` (`-y`) option, which attempts to find a basis file for a
3255 file that is being created from scratch. The current algorithm only looks in
3256 the destination directory for the created file, but it does attempt to find
3257 a match based on size/mod-time (in case the file was renamed with no other
3258 changes) as well as based on a fuzzy name-matching algorithm. This option
3259 requires protocol 29 because it needs the new file-sorting order. (Promoted
3260 from patches dir and enhanced.) (Requires protocol 29.)
3262 - Added the `--remove-sent-files` option, which lets you move files between
3265 - The hostname in HOST:PATH or HOST::PATH may now be an IPv6 literal enclosed
3266 in '[' and ']' (e.g. `[::1]`). (We already allowed IPv6 literals in the
3267 rsync://HOST:PORT/PATH format.)
3269 - When rsync recurses to build the file list, it no longer keeps open one or
3270 more directory handles from the dir's parent dirs.
3272 - When building under windows, the default for `--daemon` is now to avoid
3273 detaching, requiring the new `--detach` option to force rsync to detach.
3275 - The `--dry-run` option can now be combined with either `--write-batch` or
3276 `--read-batch`, allowing you to run a do-nothing test command to see what
3277 would happen without `--dry-run`.
3279 - The daemon's `read only` config item now sets an internal `read_only`
3280 variable that makes extra sure that no write/delete calls on the read-only
3283 - The log-format % escapes can now have a numeric field width in between the %
3284 and the escape letter (e.g. `%-40n %08p`).
3286 - Improved the option descriptions in the `--help` text.
3290 - Added atomic-rsync to the support dir: a perl script that will transfer some
3291 files using rsync, and then move the updated files into place all at once at
3292 the end of the transfer. Only works when pulling, and uses `--link-dest` and
3293 a parallel hierarchy of files to effect its update.
3295 - Added mnt-excl to the support dir: a perl script that takes the /proc/mounts
3296 file and translates it into a set of excludes that will exclude all mount
3297 points (even mapped mounts to the same disk). The excludes are made relative
3298 to the specified source dir and properly anchored.
3300 - Added savetransfer.c to the support dir: a C program that can make a copy of
3301 all the data that flows over the wire. This lets you test for data
3302 corruption (by saving the data on both the sending side and the receiving
3303 side) and provides one way to debug a protocol error.
3305 - Added rrsync to the support dir: this is an updated version of Joe Smith's
3306 restricted rsync perl script. This helps to ensure that only certain rsync
3307 commands can be run by an ssh invocation.
3311 - Added better checking of the checksum-header values that come over the
3314 - Merged a variety of file-deleting functions into a single function so that
3315 it is easier to maintain.
3317 - Improved the type of some variables (particularly blocksize vars) for
3318 consistency and proper size.
3320 - Got rid of the uint64 type (which we didn't need).
3322 - Use a slightly more compatible set of core #include directives.
3324 - Defined int32 in a way that ensures that the build dies if we can't find a
3325 variable with at least 32 bits.
3327 ### PROTOCOL DIFFERENCES FOR VERSION 29:
3329 - A 16-bit flag-word is transmitted after every file-list index. This
3330 indicates what is changing between the sender and the receiver. The
3331 generator now transmits an index and a flag-word to indicate when dirs and
3332 symlinks have changed (instead of producing a message), which makes the
3333 outputting of the information more consistent and less prone to screen
3334 corruption (because the local receiver/sender is now outputting all the
3335 file-change info messages).
3337 - If a file is being hard-linked, the `ITEM_XNAME_FOLLOWS` bit is enabled in
3338 the flag-word and the name of the file that was linked immediately follows
3339 in vstring format (see below).
3341 - If a file is being transferred with an alternate-basis file, the
3342 `ITEM_BASIS_TYPE_FOLLOWS` bit is enabled in the flag-word and a single byte
3343 follows, indicating what type of basis file was chosen. If that indicates
3344 that a fuzzy-match was selected, the `ITEM_XNAME_FOLLOWS` bit is set in the
3345 flag-word and the name of the match in vstring format follows the basis
3346 byte. A vstring is a variable length string that has its size written prior
3347 to the string, and no terminating null. If the string is from 1-127 bytes,
3348 the length is a single byte. If it is from 128-32767 bytes, the length is
3349 written as ((len >> 8) | 0x80) followed by (len % 0x100).
3351 - The sending of exclude names is done using filter-rule syntax. This means
3352 that all names have a prefixed rule indicator, even excludes (which used to
3353 be sent as a bare pattern, when possible). The `-C` option will include the
3354 per-dir .cvsignore merge file in the list of filter rules so it is
3355 positioned correctly (unlike in some older transfer scenarios).
3357 - Rsync sorts the filename list in a different way: it sorts the subdir names
3358 after the non-subdir names for each dir's contents, and it always puts a
3359 dir's contents immediately after the dir's name in the list. (Previously an
3360 item named `foo.txt` would sort in between directory `foo/` and `foo/bar`.)
3362 - When talking to a protocol 29 rsync daemon, a list-only request is able to
3363 note this before the options are sent over the wire and the new
3364 `--list-only` option is included in the options.
3366 - When the `--stats` bytes are sent over the wire (or stored in a batch), they
3367 now include two elapsed-time values: one for how long it took to build the
3368 file-list, and one for how long it took to send it over the wire (each
3369 expressed in thousandths of a second).
3371 - When `--delete-excluded` is specified with some filter rules (AKA excludes),
3372 a client sender will now initiate a send of the rules to the receiver (older
3373 protocols used to omit the sending of excludes in this situation since there
3374 were no receiver-specific rules that survived `--delete-excluded` back
3375 then). Note that, as with all the filter-list sending, only items that are
3376 significant to the other side will actually be sent over the wire, so the
3377 filter-rule list that is sent in this scenario is often empty.
3379 - An index equal to the file-list count is sent as a keep-alive packet from
3380 the generator to the sender, which then forwards it on to the receiver. This
3381 normally invalid index is only a valid keep-alive packet if the 16-bit
3382 flag-word that follows it contains a single bit (`ITEM_IS_NEW`, which is
3383 normally an illegal flag to appear alone).
3385 - A protocol-29 batch file includes a bit for the setting of the `--dirs`
3386 option and for the setting of the `--compress` option. Also, the shell
3387 script created by `--write-batch` will use the `--filter` option instead of
3388 `--exclude-from` to capture any filter rules.
3392 - Handle an operating system that use mkdev() in place of makedev().
3394 - Improved configure to better handle cross-compiling.
3396 ------------------------------------------------------------------------------
3398 # NEWS for rsync 2.6.3 (30 Sep 2004)
3400 ## Changes in this version:
3404 - A bug in the `sanitize_path` routine (which affects a non-chrooted rsync
3405 daemon) could allow a user to craft a pathname that would get transformed
3406 into an absolute path for certain options (but not for file-transfer names).
3407 If you're running an rsync daemon with chroot disabled, **please upgrade**,
3408 ESPECIALLY if the user privs you run rsync under is anything above `nobody`.
3410 OUTPUT CHANGES (ATTN: those using a script to parse the verbose output):
3412 - Please note that the 2-line footer (output when verbose) now uses the term
3413 `sent` instead of `wrote` and `received` instead of `read`. If you are not
3414 parsing the numeric values out of this footer, a script would be better off
3415 using the empty line prior to the footer as the indicator that the verbose
3418 - The output from the `--stats` option was similarly affected to change
3419 `written` to `sent` and `read` to `received`.
3421 - Rsync ensures that a filename that contains a newline gets mentioned with
3422 each newline transformed into a question mark (which prevents a filename
3423 from causing an empty line to be output).
3425 - The `backed up ...` message that is output when at least 2 `--verbose`
3426 options are specified is now the same both with and without the
3427 `--backup-dir` option.
3431 - Fixed a crash bug that might appear when `--delete` was used and multiple
3432 source directories were specified.
3434 - Fixed a 32-bit truncation of the file length when generating the checksums.
3436 - The `--backup` code no longer attempts to create some directories over and
3437 over again (generating warnings along the way).
3439 - Fixed a bug in the reading of the secrets file (by the daemon) and the
3440 password file (by the client): the files no longer need to be terminated by
3441 a newline for their content to be read in.
3443 - If a file has a read error on the sending side or the reconstructed data
3444 doesn't match the expected checksum (perhaps due to the basis file changing
3445 during the transfer), the receiver will no longer retain the resulting file
3446 unless the `--partial` option was specified. (Note: for the read-error
3447 detection to work, neither side can be older than 2.6.3 -- older receivers
3448 will always retain the file, and older senders don't tell the receiver that
3449 the file had a read error.)
3451 - If a file gets resent in a single transfer and the `--backup` option is
3452 enabled, rsync no longer performs a duplicate backup (it used to overwrite
3453 the original file in the backup area).
3455 - Files specified in the daemon's `exclude` or `exclude from` config items are
3456 now excluded from being uploaded (assuming that the module allows uploading
3457 at all) in addition to the old download exclusion.
3459 - Got rid of a potential hang in the receiver when near the end of a phase.
3461 - When using `--backup` without a `--backup-dir`, rsync no longer preserves
3462 the modify time on directories. This avoids confusing NFS.
3464 - When `--copy-links` (`-L`) is specified, we now output a separate error for
3465 a symlink that has no referent instead of claiming that a file `vanished`.
3467 - The `--copy-links` (`-L`) option no longer has the side-effect of telling
3468 the receiving side to follow symlinks. See the `--keep-dirlinks` option
3469 (mentioned below) for a way to specify that behavior.
3471 - Error messages from the daemon server's option-parsing (such as refused
3472 options) are now successfully transferred back to the client (the server
3473 used to fail to send the message because the socket wasn't in the right
3474 state for the message to get through).
3476 - Most transfer errors that occur during a daemon transfer are now returned to
3477 the user in addition to being logged (some messages are intended to be
3478 daemon-only and are not affected by this).
3480 - Fixed a bug in the daemon authentication code when using one of the
3481 batch-processing options.
3483 - We try to work around some buggy IPv6 implementations that fail to implement
3484 `IPV6_V6ONLY`. This should fix the `address in use` error that some daemons
3485 get when running on an OS with a buggy IPv6 implementation. Also, if the new
3486 code gets this error, we might suggest that the user specify `--ipv4` or
3487 `--ipv6` (if we think it will help).
3489 - When the remote rsync dies, make a better effort to recover any error
3490 messages it may have sent before dying (the local rsync used to just die
3491 with a socket-write error).
3493 - When using `--delete` and a `--backup-dir` that contains files that are
3494 hard-linked to their destination equivalents, rsync now makes sure that
3495 removed files really get removed (avoids a really weird rename() behavior).
3497 - Avoid a bogus run-time complaint about a lack of 64-bit integers when the
3498 int64 type is defined as an `off_t` and it actually has 64-bits.
3500 - Added a configure check for open64() without mkstemp64() so that we can
3501 avoid using mkstemp() when such a combination is encountered. This bypasses
3502 a problem writing out large temp files on OSes such as AIX and HP-UX.
3504 - Fixed an age-old crash problem with `--read-batch` on a local copy (rsync
3505 was improperly assuming `--whole-file` for the local copy).
3507 - When `--dry-run` (`-n`) is used and the destination directory does not
3508 exist, rsync now produces a correct report of files that would be sent
3509 instead of dying with a chdir() error.
3511 - Fixed a bug that could cause a slow-to-connect rsync daemon to die with an
3512 error instead of waiting for the connection to finish.
3514 - Fixed an ssh interaction that could cause output to be lost when the user
3515 chose to combine the output of rsync's stdout and stderr (e.g. using the
3518 - Fixed an option-parsing bug when `--files-from` got passed to a daemon.
3522 - Added the `--partial-dir=DIR` option that lets you specify where to
3523 (temporarily) put a partially transferred file (instead of overwriting the
3524 destination file). E.g. `--partial-dir=.rsync-partial` Also added support
3525 for the `RSYNC_PARTIAL_DIR` environment variable that, when found,
3526 transforms a regular `--partial` option (such as the convenient `-P` option)
3527 into one that also specifies a directory.
3529 - Added `--keep-dirlinks` (`-K`), which allows you to symlink a directory onto
3530 another partition on the receiving side and have rsync treat it as matching
3531 a normal directory from the sender.
3533 - Added the `--inplace` option that tells rsync to write each destination file
3534 without using a temporary file. The matching of existing data in the
3535 destination file can be severely limited by this, but there are also cases
3536 where this is more efficient (such as appending data). Use only when needed
3537 (see the man page for more details).
3539 - Added the `write only` option for the daemon's config file.
3541 - Added long-option names for `-4` and `-6` (namely `--ipv4` and `--ipv6`) and
3542 documented all these options in the man page.
3544 - Improved the handling of the `--bwlimit` option so that it's less bursty,
3545 more accurate, and works properly over a larger range of values.
3547 - The rsync daemon-over-ssh code now looks for `SSH_CONNECTION` and
3548 `SSH2_CLIENT` in addition to `SSH_CLIENT` to figure out the IP address.
3550 - Added the `--checksum-seed=N` option for advanced users.
3552 - Batch writing/reading has a brand-new implementation that is simpler, fixes
3553 a few weird problems with the old code (such as no longer sprinkling the
3554 batch files into different dirs or even onto different systems), and is much
3555 less intrusive into the code (making it easier to maintain for the future).
3556 The new code generates just one data file instead of three, which makes it
3557 possible to read the batch on stdin via a remote shell. Also, the old
3558 requirement of forcing the same fixed checksum-seed for all batch processing
3561 - If an rsync daemon has a module set with `list = no` (which hides its
3562 presence in the list of available modules), a user that fails to
3563 authenticate gets the same `unknown module` error that they would get if the
3564 module were actually unknown (while still logging the real error to the
3565 daemon's log file). This prevents fishing for module names.
3567 - The daemon's `refuse options` config item now allows you to match option
3568 names using wildcards and/or the single-letter option names.
3570 - Each transferred file now gets its permissions and modified-time updated
3571 before the temp-file gets moved into place. Previously, the finished file
3572 would have a very brief window where its permissions disallowed all group
3575 - Added the ability to parse a literal IPv6 address in an `rsync:` URL (e.g.
3576 rsync://[2001:638:500:101::21]:873/module/dir).
3578 - The daemon's wildcard expanding code can now handle more than 1000 filenames
3579 (it's now limited by memory instead of having a hard-wired limit).
3583 - Some cleanup in the exclude code has saved some per-exclude memory and made
3584 the code easier to maintain.
3586 - Improved the argv-overflow checking for a remote command that has a lot of
3589 - Use rsyserr() in the various places that were still calling rprintf() with
3590 strerror() as an arg.
3592 - If an rsync daemon is listening on multiple sockets (to handle both IPv4 and
3593 IPv6 to a single port), we now close all the unneeded file handles after we
3594 accept a connection (we used to close just one of them).
3596 - Optimized the handling of larger block sizes (rsync used to slow to a crawl
3597 if the block size got too large).
3599 - Optimized away a loop in `hash_search()`.
3601 - Some improvements to the `sanitize_path()` and `clean_fname()` functions
3602 makes them more efficient and produce better results (while still being
3603 compatible with the file-name cleaning that gets done on both sides when
3604 sending the file-list).
3606 - Got rid of `alloc_sanitize_path()` after adding a destination-buffer arg to
3607 `sanitize_path()` made it possible to put all the former's functionality
3610 - The file-list that is output when at least 4 verbose options are specified
3611 reports the uid value on the sender even when rsync is not running as root
3612 (since we might be sending to a root receiver).
3616 - Added a `gen` target to rebuild most of the generated files, including
3617 configure, config.h.in, the man pages, and proto.h.
3619 - If `make proto` doesn't find some changes in the prototypes, the proto.h
3620 file is left untouched (its time-stamp used to always be updated).
3622 - The variable `$STRIP` (that is optionally set by the install-strip target's
3623 rule) was changed to `$INSTALL_STRIP` because some systems have `$STRIP`
3624 already set in the environment.
3626 - Fixed a build problem when `SUPPORT_HARD_LINKS` isn't defined.
3628 - When cross-compiling, the gettimeofday() function is now assumed to be a
3629 modern version that takes two-args (since we can't test it).

3639 ------------------------------------------------------------------------------
3641 # NEWS for rsync 2.6.2 (30 Apr 2004)
3643 ## Changes in this version:
3647 - Fixed a major bug in the sorting of the filenames when `--relative` is used
3648 for some sources (just sources such as `/` and `/*` were affected). This fix
3649 ensures that we ask for the right file-list item when requesting changes
3652 - Rsync now checks the return value of the close() function to better report
3653 disk-full problems on an NFS file system.
3655 - Restored the old daemon-server behavior of logging error messages rather
3656 than returning them to the user. (A better long-term fix will be sought in
3659 - An obscure uninitialized-variable bug was fixed in the uid/gid code. (This
3660 bug probably had no ill effects.)
3664 - Got rid of the configure check for sys/sysctl.h (it wasn't used and was
3665 causing a problem on some systems). Also improved the
3666 broken-largefile-locking test to try to avoid failure due to an NFS
3669 - Fixed a compile problem on systems that don't define `AI_NUMERICHOST`.
3671 - Fixed a compile problem in the popt source for compilers that don't support
3674 ### DEVELOPER RELATED:
3676 - Improved the testsuite's `merge` test to work on OSF1.

3682 # NEWS for rsync 2.6.1 (26 Apr 2004)
3684 ## Changes in this version:
3686 ### PROTOCOL NUMBER:
3688 - The protocol number was changed to 28.
3692 - Paths sent to an rsync daemon are more thoroughly sanitized when chroot is
3693 not used. If you're running a non-read-only rsync daemon with chroot
3694 disabled, **please upgrade**, ESPECIALLY if the user privs you run rsync
3695 under is anything above `nobody`.
3699 - Lower memory use, more optimal transfer of data over the socket, and lower
3700 CPU usage (see the INTERNAL section for details).
3702 - The `RSYNC_PROXY` environment variable can now contain a `USER:PASS@` prefix
3703 before the `HOST:PORT` information. (Bardur Arantsson)
3705 - The `--progress` output now mentions how far along in the transfer we are,
3706 including both a count of files transferred and a percentage of the total
3707 file-count that we've processed. It also shows better
3708 current-rate-of-transfer and remaining-transfer-time values.
3710 - Documentation changes now attempt to describe some often misunderstood
3711 features more clearly.
3715 - When `-x` (`--one-file-system`) is combined with `-L` (`--copy-links`) or
3716 `--copy-unsafe-links,` no symlinked files are skipped, even if the referent
3717 file is on a different filesystem.
3719 - The `--link-dest` code now works properly for a non-root user when (1) the
3720 UIDs of the source and destination differ and `-o` was specified, or (2)
3721 when the group of the source can't be used on the destination and `-g` was
3724 - Fixed a bug in the handling of `-H` (hard-links) that might cause the
3725 expanded PATH/NAME value of the current item to get overwritten (due to an
3726 expanded-name caching bug).
3728 - We now reset the `new data has been sent` flag at the start of each file we
3729 send. This makes sure that an interrupted transfer with the `--partial`
3730 option set doesn't keep a shorter temp file than the current basis file when
3731 no new data has been transferred over the wire for that file.
3733 - Fixed a byte-order problem in `--batch-mode` on big-endian machines. (Jay
3736 - When using `--cvs-exclude`, the exclude items we get from a per-directory's
3737 .cvsignore file once again only affect that one directory (not all following
3738 directories too). The items are also now properly word-split and parsed
3739 without any +/- prefix parsing.
3741 - When specifying the USER@HOST: prefix for a file, the USER part can now
3742 contain an '@', if needed (i.e. the last '@' is used to find the HOST, not
3745 - Fixed some bugs in the handling of group IDs for non-root users: (1) It
3746 properly handles a group that the sender didn't have a name for (it would
3747 previously skip changing the group on any files in that group). (2) If
3748 `--numeric-ids` is used, rsync no longer attempts to set groups that the
3749 user doesn't have the permission to set.
3751 - Fixed the `refuse options` setting in the rsyncd.conf file.
3753 - Improved the `-x` (`--one-file-system`) flag's handling of any mount-point
3754 directories we encounter. It is both more optimal (in that it no longer does
3755 a useless scan of the contents of the mount-point dirs) and also fixes a
3756 bug where a remapped mount of the original filesystem could get discovered
3757 in a subdir we should be ignoring.
3759 - Rsync no longer discards a double-slash at the start of a filename when
3760 trying to open the file. It also no longer constructs names that start with
3761 a double slash (unless the user supplied them).
3763 - Path-specifying options to a daemon should now work the same with or without
3764 chroot turned on. Previously, such a option (such as `--link-dest`) would
3765 get its absolute path munged into a relative one if chroot was not on,
3766 making that setting fairly useless. Rsync now transforms the path into one
3767 that is based on the module's base dir when chroot is not enabled.
3769 - Fixed a compatibility problem interacting with older rsync versions that
3770 might send us an empty `--suffix` value without telling us that
3771 `--backup-dir` was specified.
3773 - The `hosts allow` option for a daemon-over-remote-shell process now has
3774 improved support for IPv6 addresses and a fix for systems that have a length
3775 field in their socket structs.
3777 - Fixed the ability to request an empty backup `--suffix` when sending files
3780 - Fixed an option-parsing bug when `--files-from` was sent to a server sender.
3784 - Most of the I/O is now buffered, which results in a pretty large speedup
3785 when running under MS Windows. (Craig Barratt)
3787 - Optimizations to the name-handling/comparing code have made some significant
3788 reductions in user-CPU time for large file sets.
3790 - Some cleanup of the variable types make the code more consistent.
3792 - Reduced memory requirements of hard link preservation. (J.W. Schultz)
3794 - Implemented a new algorithm for hard-link handling that speeds up the code
3795 significantly. (J.W. Schultz and Wayne Davison)
3797 - The `--hard-link` option now uses the first existing file in the group of
3798 linked files as the basis for the transfer. This prevents the sub-optimal
3799 transfer of a file's data when a new hardlink is added on the sending side
3800 and it sorts alphabetically earlier in the list than the files that are
3801 already present on the receiving side.
3803 - Dropped support for protocol versions less than 20 (2.3.0 released 15 Mar
3804 1999) and activated warnings for protocols less than 25 (2.5.0 released 23
3805 Aug 2001). (Wayne Davison and J.W. Schultz, severally)
3807 - More optimal data transmission for `--hard-links` (protocol 28).
3809 - More optimal data transmission for `--checksum` (protocol 28).
3811 - Less memory is used when `--checksum` is specified.
3813 - Less memory is used in the file list (a per-file savings).
3815 - The generator is now better about not modifying the file list during the
3816 transfer in order to avoid a copy-on-write memory bifurcation (on systems
3817 where fork() uses shared memory). Previously, rsync's shared memory would
3818 slowly become unshared, resulting in real memory usage nearly doubling on
3819 the receiving side by the end of the transfer. Now, as long as permissions
3820 are being preserved, the shared memory should remain that way for the entire
3823 - Changed hardlink info and `file_struct` + strings to use allocation pools.
3824 This reduces memory use for large file-sets and permits freeing memory to
3825 the OS. (J.W. Schultz)
3827 - The 2 pipes used between the receiver and generator processes (which are
3828 forked on the same machine) were reduced to 1 pipe and the protocol improved
3829 so that (1) it is now impossible to have the `redo` pipe fill up and hang
3830 rsync, and (2) trailing messages from the receiver don't get lost on their
3831 way through the generator over to the sender (which mainly affected
3832 hard-link messages and verbose `--stats` output).
3834 - Improved the internal uid/gid code to be more portable and a little more
3837 - The device numbers sent when using `--devices` are now sent as separate
3838 major/minor values with 32-bit accuracy (protocol 28). Previously, the
3839 copied devices were sent as a single 32-bit number. This will make
3840 inter-operation of 64-bit binaries more compatible with their 32-bit
3841 brethren (with both ends of the connection are using protocol 28). Note that
3842 optimizations in the binary protocol for sending the device numbers often
3843 results in fewer bytes being used than before, even though more precision is
3846 - Some cleanup of the exclude/include structures and its code made things
3847 clearer (internally), simpler, and more efficient.
3849 - The reading & writing of the file-list in batch-mode is now handled by the
3850 same code that sends & receives the list over the wire. This makes it much
3851 easier to maintain. (Note that the batch code is still considered to be
3856 - The configure script now accepts `--with-rsyncd-conf=PATH` to override the
3857 default value of the /etc/rsyncd.conf file.
3859 - Fixed configure bug when running `./configure --disable-ipv6`.
3861 - Fixed compilation problem on Tru64 Unix (having to do with `sockaddr.sa_len`
3862 and `sockaddr.sin_len`).
3864 ### DEVELOPER RELATED:
3866 - Fixed `make test` bug when build dir is not the source dir.
3868 - Added a couple extra diffs in the `patches` dir, removed the ones that got
3869 applied, and rebuilt the rest.
3871 ------------------------------------------------------------------------------
3873 # NEWS for rsync 2.6.0 (1 Jan 2004)
3875 ## Changes in this version:
3877 ### PROTOCOL NUMBER:
3879 - The protocol number was changed to 27. The maximum accepted protocol number
3880 was increased from 30 to 40.
3884 - `ssh` is now the default remote shell for rsync. If you want to change this,
3885 configure like this: `./configure --with-rsh=rsh`.
3887 - Added `--files-from`, `--no-relative`, `--no-implied-dirs`, and `--from0`.
3888 Note that `--from0` affects the line-ending character for all the files read
3889 by the `--*-from` options. (Wayne Davison)
3891 - Length of csum2 is now per-file starting with protocol version
3894 - Per-file dynamic block size is now sqrt(file length). The per-file checksum
3895 size is determined according to an algorithm provided by Donovan Baarda
3896 which reduces the probability of rsync algorithm corrupting data and falling
3897 back using the whole md4 checksums. (J.W. Schultz, Donovan Baarda)
3899 - The `--stats` option no longer includes the (debug) malloc summary unless
3900 the verbose option was specified at least twice.
3902 - Added a new error/warning code for when files vanish from the sending side.
3903 Made vanished source files not interfere with the file-deletion pass when
3904 `--delete-after` was specified.
3906 - Various trailing-info sections are now preceded by a newline.
3910 - Fixed several exclude/include matching bugs when using wild-cards. This has
3911 a several user-visible effects, all of which make the matching more
3912 consistent and intuitive. This should hopefully not cause anyone problems
3913 since it makes the matching work more like what people are expecting. (Wayne
3916 - A pattern with a `**` no longer causes a `*` to match slashes. For example,
3917 with `/*/foo/**`, `foo` must be 2 levels deep. [If your string has BOTH `*`
3918 and `**` wildcards, changing the `*` wildcards to `**` will provide the old
3919 behavior in all versions.]
3921 - `**/foo` now matches at the base of the transfer (like /foo does). [Use
3922 `/**/foo` to get the old behavior in all versions.]
3924 - A non-anchored wildcard term floats to match beyond the base of the
3925 transfer. E.g. `CVS/R*` matches at the end of the path, just like the
3926 non-wildcard term `CVS/Root` does. [Use `/CVS/R*` to get the old behavior in
3929 - Including a `**` in the match term causes it to be matched against the
3930 entire path, not just the name portion, even if there aren't any interior
3931 slashes in the term. E.g. `foo**bar` would exclude `/path/foo-bar` (just
3932 like before) as well as `/foo-path/baz-bar` (unlike before). [Use `foo*bar`
3933 to get the old behavior in all versions.]
3935 - The exclude list specified in the daemon's config file is now properly
3936 applied to the pulled items no matter how deep the user's file-args are in
3937 the source tree. (Wayne Davison)
3939 - For protocol version >= 27, `mdfour_tail()` is called when the block size
3940 (including `checksum_seed`) is a multiple of 64. Previously it was not
3941 called, giving the wrong MD4 checksum. (Craig Barratt)
3943 - For protocol version >= 27, a 64 bit bit counter is used in mdfour.c as
3944 required by the RFC. Previously only a 32 bit bit counter was used, causing
3945 incorrect MD4 file checksums for file sizes >= 512MB - 4. (Craig Barratt)
3947 - Fixed a crash bug when interacting with older rsync versions and multiple
3948 files of the same name are destined for the same dir. (Wayne Davison)
3950 - Keep tmp names from overflowing MAXPATHLEN.
3952 - Make `--link-dest` honor the absence of `-p`, `-o`, and `-g`.
3954 - Made rsync treat a trailing slash in the destination in a more consistent
3957 - Fixed file I/O error detection. (John Van Essen)
3959 - Fixed bogus `malformed address {hostname}` message in rsyncd log when
3960 checking IP address against hostnames from `hosts allow` and `hosts deny`
3961 parameters in config file.
3963 - Print heap statistics when verbose >= 2 instead of when >= 1.
3965 - Fixed a compression (`-z`) bug when syncing a mostly-matching file that
3966 contains already-compressed data. (Yasuoka Masahiko and Wayne Davison)
3968 - Fixed a bug in the `--backup` code that could cause deleted files to not get
3971 - When the backup code makes new directories, create them with mode 0700
3972 instead of 0755 (since the directory permissions in the backup tree are not
3973 yet copied from the main tree).
3975 - Call setgroups() in a more portable manner.
3977 - Improved file-related error messages to better indicate exactly what
3978 pathname failed. (Wayne Davison)
3980 - Fixed some bugs in the handling of `--delete` and `--exclude` when using the
3981 `--relative` (`-R`) option. (Wayne Davison)
3983 - Fixed bug that prevented regular files from replacing special files and
3984 caused a directory in `--link-dest` or `--compare-dest` to block the
3985 creation of a file with the same path. A directory still cannot be replaced
3986 by a regular file unless `--delete` specified. (J.W. Schultz)
3988 - Detect and report when open or opendir succeed but read and readdir fail
3989 caused by network filesystem issues and truncated files. (David Norwood,
3990 Michael Brown, J.W. Schultz)
3992 - Added a fix that should give ssh time to restore the tty settings if the
3993 user presses Ctrl-C at an ssh password prompt.
3997 - Eliminated vestigial support for old versions that we stopped supporting.
4000 - Simplified some of the option-parsing code. (Wayne Davison)
4002 - Some cleanup made to the exclude code, as well as some new defines added to
4003 enhance readability. (Wayne Davison)
4005 - Changed the protocol-version code so that it can interact at a lower
4006 protocol level than the maximum supported by both sides. Added an
4007 undocumented option, `--protocol=N`, to force the value we advertise to the
4008 other side (primarily for testing purposes). (Wayne Davison)

4023 # NEWS for rsync 2.5.6, aka "the dwd-between-jobs release" (26 Jan 2003)
4025 ## Changes in this version:
4029 - The `--delete-after` option now implies `--delete`. (Wayne Davison)
4031 - The `--suffix` option can now be used with `--backup-dir`. (Michael
4034 - Combining `::` syntax with the `--rsh`/`-e` option now uses the specified
4035 remote-shell as a transport to talk to a (newly-spawned) server-daemon. This
4036 allows someone to use daemon features, such as modules, over a secure
4037 protocol, such as ssh. (JD Paul)
4039 - The rsync:// syntax for daemon connections is now accepted in the
4042 - If the file name given to `--include-from` or `--exclude-from` is `-`, rsync
4043 will read from standard input. (J.W. Schultz)
4045 - New option `--link-dest` which is like `--compare-dest` except that
4046 unchanged files are hard-linked in to the destination directory. (J.W.
4049 - Don't report an error if an excluded file disappears during an rsync run.
4050 (Eugene Chupriyanov and Bo Kersey)
4052 - Added .svn to `--cvs-exclude` list to support subversion. (Jon Middleton)
4054 - Properly support IPv6 addresses in the rsyncd.conf `hosts allow` and `hosts
4055 deny` fields. (Hideaki Yoshifuji)
4057 - Changed exclude file handling to permit DOS or MAC style line terminations.
4060 - Ignore errors from chmod when `-p`/`-a`/`--preserve-perms` is not set.
4065 - Fix `forward name lookup failed` errors on AIX 4.3.3. (John L. Allen, Martin
4068 - Generate each file's rolling-checksum data as we send it, not in a separate
4069 (memory-eating) pass before hand. This prevents timeout errors on really
4070 large files. (Stefan Nehlsen)
4072 - Fix compilation on Tru64. (Albert Chin, Zoong Pham)
4074 - Better handling of some client-server errors. (Martin Pool)
4076 - Fixed a crash that would occur when sending a list of files that contains a
4077 duplicate name (if it sorts to the end of the file list) and using
4078 `--delete`. (Wayne Davison)
4080 - Fixed the file-name duplicate-removal code when dealing with multiple dups
4081 in a row. (Wayne Davison)
4083 - Fixed a bug that caused rsync to lose the exit status of its child processes
4084 and sometimes return an exit code of 0 instead of showing an error. (David
4085 R. Staples, Dave Dykstra)
4087 - Fixed bug in `--copy-unsafe-links` that caused it to be completely broken.
4090 - Prevent infinite recursion in cleanup code under certain circumstances.
4091 (Sviatoslav Sviridov and Marc Espie)
4093 - Fixed a bug that prevented rsync from creating intervening directories when
4094 `--relative-paths`/`-R` is set. (Craig Barratt)
4096 - Prevent `Connection reset by peer` messages from Cygwin. (Randy O'Meara)
4100 - Many code cleanups and improved internal documentation. (Martin Pool, Nelson
4103 - Portability fixes. (Dave Dykstra and Wayne Davison)
4105 - More test cases. (Martin Pool)
4107 - Some test-case fixes. (Brian Poole, Wayne Davison)
4109 - Updated included popt to the latest vendor drop, version 1.6.4. (Jos
4112 - Updated config.guess and config.sub to latest versions; this means rsync
4113 should build on more platforms. (Paul Green)
4115 ------------------------------------------------------------------------------
4117 # NEWS for rsync 2.5.5, aka Snowy River (2 Apr 2002)
4119 ## Changes in this version:
4123 - With `--progress`, when a transfer is complete show the time taken;
4124 otherwise show expected time to complete. (Cameron Simpson)
4126 - Make `make install-strip` works properly, and `make install` accepts a
4127 DESTDIR variable for help in building binary packages. (Peter
4128 Breitenlohner, Greg Louis)
4130 - If configured with `--enable-maintainer-mode`, then on receipt of a fatal
4131 signal rsync will try to open an xterm running gdb, similarly to Samba's
4132 `panic action` or GNOME's bug-buddy. (Martin Pool)
4136 - Fix situation where failure to fork (e.g. because out of process slots)
4137 would cause rsync to kill all processes owned by the current user. Yes,
4138 really! (Paul Haas, Martin Pool)
4140 - Fix test suite on Solaris. (Jos Backus, Martin Pool)
4142 - Fix minor memory leak in socket code. (Dave Dykstra, Martin Pool.)
4144 - Fix `--whole-file` problem that caused it to be the default even for remote
4145 connections. (Martin Pool, Frank Schulz)
4147 - Work around bug in Mac OS X mkdir(2), which cannot handle trailing slashes.
4148 <http://www.opensource.apple.com/bugs/X/BSD%20Kernel/2734739.html> (Martin
4151 - Improved network error handling. (Greg A. Woods)
4153 ------------------------------------------------------------------------------
4155 # NEWS for rsync 2.5.4, aka "Imitation lizard skin" (13 Mar 2002)
4157 ## Changes in this version:
4161 - Additional fix for zlib double-free bug. (Martin Pool, Andrew Tridgell) (CVE
4166 - Merge in changes from zlib 1.1.3 to zlib 1.1.4. (Jos Backus) (Note that
4167 rsync still uses a custom version of zlib; you can not just link against a
4168 system library. See zlib/README.rsync)
4170 - Additional test cases for `--compress`. (Martin Pool)
4172 ------------------------------------------------------------------------------
4174 # NEWS for rsync 2.5.3, aka "Happy 26" (11 Mar 2002)
4176 ## Changes in this version:
4180 - Make sure that supplementary groups are removed from a server
4181 process after changing uid and gid. (Ethan Benson) (Debian bug
4182 #132272, CVE CAN-2002-0080)
4186 - Fix zlib double-free bug. (Owen Taylor, Mark J Cox) (CVE CAN-2002-0059)
4188 - Fixed problem that in many cases caused the error message unexpected read
4189 size of 0 in `map_ptr` and resulted in the wrong data being copied.
4191 - Fixed compilation errors on some systems caused by the use of `unsigned
4194 - Fixed problem on systems such as Sunos4 that do not support realloc on a
4195 NULL pointer; error was 'out of memory in "flist_expand"'.
4197 - Fix for rsync server processes hanging around after the client unexpectedly
4198 disconnects. (Colin Walters) (Debian bug #128632)
4200 - Cope with BSD systems on which mkdir() will not accept a trailing slash.
4204 - Merge in changes from zlib 1.1.2 to zlib 1.1.3. (Note that rsync still uses
4205 a custom version of zlib; you can not just link against a system library.
4206 See zlib/README.rsync)
4208 - Command to initiate connections is only shown with `-vv`, rather than `-v`
4209 as in 2.5.2. Output from plain `-v` is more similar to what was historically
4210 used so as not to break scripts that try to parse the output.
4212 - Added `--no-whole-file` and `--no-blocking-io` options (Dave Dykstra)
4214 - Made the `--write-batch` and `--read-batch` options actually work and added
4215 documentation in the man page (Jos Backus)
4217 - If the daemon is unable to fork a child to accept a connection, print an
4218 error message. (Colin Walters)
4220 ------------------------------------------------------------------------------
4222 # NEWS for rsync 2.5.2 (26 Jan 2002)
4224 ## Changes in this version:
4228 - Signedness security patch from Sebastian Krahmer <krahmer@suse.de> -- in
4229 some cases we were not sufficiently careful about reading integers from the
4232 ### PROTOCOL NUMBER:
4234 - The protocol number was changed to 26.
4238 - Fix possible string mangling in log files.
4240 - Fix for setting local address of outgoing sockets.
4242 - Better handling of hardlinks and devices on platforms with 64-bit `dev_t` or
4245 - Name resolution on machines supporting IPv6 is improved.
4247 - Fix for device nodes. (dann frazier) (Debian #129135)
4251 - With `-v`, rsync now shows the command used to initiate an ssh/rsh
4254 - `--statistics` now shows memory heap usage on platforms that support
4257 - "The Ted T'so school of program optimization": make progress visible and
4258 people will think it's faster. (With `--progress`, rsync will show you how
4259 many files it has seen as it builds the `file_list`, giving some indication
4260 that it has not hung.)
4262 - Improvements to batch mode support. This is still experimental but testing
4263 would be welcome. (Jos Backus)
4265 - New `--ignore-existing` option, patch previously distributed with Vipul's
4266 Razor. (Debian #124286)
4268 ------------------------------------------------------------------------------
4270 # NEWS for rsync 2.5.1 (3 Jan 2002)
4272 ## Changes in this version:
4276 - Fix for segfault in `--daemon` mode configuration parser. (Paul Mackerras)

4279 SUMIKAWA Munechika and Jun-ichiro `itojun` Hagino)
4281 - Various fixes for IPv6 support. (Dave Dykstra)
4283 - rsync.1 typo fix. (Matt Kraai)
4285 - Test suite typo fixes. (Tom Schmidt)
4287 - rsync.1 grammar and clarity improvements. (Edward Welbourne)
4289 - Correction to ./configure tests for `inet_ntop`. (Jeff Garzik)
4293 - `--progress` and `-P` now show estimated data transfer rate (in a multiple
4294 of bytes/s) and estimated time to completion. (Rik Faith)
4296 - `--no-detach` option, required to run as a W32 service and also useful when
4297 running on Unix under daemontools, AIX's SRC, or a debugger. (Max Bowsher,
4300 - Clearer error messages for some conditions.
4302 ------------------------------------------------------------------------------
4304 # NEWS for rsync 2.5.0 (30 Nov 2001)
4306 ## Changes in this version:
4308 ### PROTOCOL NUMBER:
4310 - The protocol number was changed to 25.
4314 - Martin Pool <mbp@samba.org> is now a co-maintainer.
4318 - Support for LSB-compliant packaging <http://www.linuxbase.org/>
4320 - Shell wildcards are allowed in `auth users` lines.
4322 - Merged UNC rsync+ patch to support creation of standalone patch sets. By
4323 Bert J. Dempsey and Debra Weiss, updated by Jos Backus.
4324 <http://www.ils.unc.edu/i2dsi/unc_rsync+.html>
4326 - IPv6 support based on a patch from KAME.net, on systems including modern
4327 versions of Linux, Solaris, and HP-UX. Also includes IPv6 compatibility
4328 functions for old OSs by the Internet Software Consortium, Paul Vixie, the
4329 OpenSSH portability project, and OpenBSD.
4333 - Include/exclude cluestick: with `-vv`, print out whether files are included
4334 or excluded and why.
4336 - Many error messages have more friendly explanations and more details.
4338 - Manual page improvements plus scanty protocol documentation.
4340 - When running as `--daemon` in the background and using a `log file`
4341 rsyncd.conf directive, close the log file every time it is open when going
4342 to sleep on the socket. This allows the log file to get cleaned out by
4345 - Change to using libpopt rather than getopt for processing options. This
4346 makes the code cleaner and the behaviour more consistent across platforms.
4347 popt is included and built if not installed on the platform.
4349 - More details in `--version`, including note about whether 64-bit files,
4350 symlinks and hardlinks are supported.
4352 - MD4 code may use less CPU cycles.
4354 - Use mkstemp on systems where it is secure. If we use mktemp, explain that we
4355 do it in a secure way.
4357 - `--whole-file` is the default when source and target are on the local
4362 - Fix for various bugs causing rsync to hang.
4364 - Attempt to fix Large File Summit support on AIX.
4366 - Attempt to fix error handling lockup bug.
4368 - Give a non-0 exit code if **any** of the files we have been asked to
4369 transfer fail to transfer.
4371 - For log messages containing ridiculously long strings that might overflow a
4372 buffer rsync no longer aborts, but rather prints an ellipsis at the end of
4373 the string. (Patch from Ed Santiago.)
4377 - Improved support for UNICOS (tested on Cray T3E and Cray SV1)
4379 - autoconf2.52 (or later) is now required to rebuild the autoconf scripts. It
4380 is not required to simply build rsync.
4382 - Platforms thought to work in this release:
