3 # NEWS for rsync 3.2.3 (UNRELEASED)
5 ## Changes in this version:
9 - Fixed a bug in the xattr code that was freeing the wrong object when trying
10 to cleanup the xattr list.
12 - Fixed a bug in the xattr code that was not leaving room for the "rsync."
13 prefix in some instances where it needed to be added.
15 - Restored the ability to use --bwlimit=0 to specify no bandwidth limit. (It
16 was accidentally broken in 3.2.2.)
20 - Allow `--max-alloc=0` to specify no limit to the alloc sanity check.
22 - Allow `--block-size=SIZE` to specify the size using units such as "100K".
24 - The name of the id-0 user & group is now sent to the receiver along with the
25 other user/group names in the transfer (instead of assuming that both sides
26 have the same id-0 names).
28 - Added the `--stop-after=MINS` and `--stop-at=DATE_TIME` options (with the
29 `--time-limit=MINS` option accepted as an alias for `--stop-after`). This
30 is an enhanced version of the time-limit patch from the patches repo.
32 - Added the ability to specify "@netgroup" names to the `hosts allow` and
33 `hosts deny` daemon parameters. This is a finalized version of the
34 netgroup-auth patch from the patches repo.
36 - Output file+line info on out-of-memory & overflow errors while also avoiding
37 the output of alternate build-dir path info that is not useful to the user.
39 - Improved the testsuite on FreeBSD.
41 - Added some compatibility code for HPE NonStop platforms.
45 - Use a simpler overflow check idiom in a few spots.
47 - Use a C99 Flexible Array for a trailing variable-size filename in a struct
48 (with a fallback to the old 1-char string kluge for older compilers).
50 ------------------------------------------------------------------------------
53 # NEWS for rsync 3.2.2 (4 Jul 2020)
55 ## Changes in this version:
59 - Avoid a crash when a daemon module enables `transfer logging` without
60 setting a `log format` value.
62 - Fixed installing rsync-ssl script from an alternate build dir.
64 - Fixed the updating of configure.sh from an alternate build dir.
66 - Apple requires the asm function name to begin with an underscore.
68 - Avoid a test failure in the daemon test when --atimes is disabled.
72 - Allow the server side to restrict checksum & compression choices via the
73 same environment variables the client uses. The env vars can be divided
74 into "client list & server list" by the "`&`" char or the same list can
77 - Simplify how the negotiation environment variables apply when interacting
78 with an older rsync and also when a list contains only invalid names.
80 - Do not allow a negotiated checksum or compression choice of "none" unless
81 the user authorized it via an environment variable or command-line option.
83 - Added the `--max-alloc=SIZE` option to be able to override the memory
84 allocator's sanity-check limit. It defaults to 1G (as before) but the error
85 message when exceeding it specifically mentions the new option so that you
86 can differentiate an out-of-memory error from a failure of this limit. It
87 also allows you to specify the value via the RSYNC_MAX_ALLOC environment
90 - Add the "open atime" daemon parameter to allow a daemon to always enable or
91 disable the use of O_NOATIME (the default is to let the user control it).
93 - The default systemd config was changed to remove the `ProtectHome=on`
94 setting since rsync is often used to serve files in /home and /root and this
95 seemed a bit too strict. Feel free to use `systemctl edit rsync` to add
96 that restriction (or maybe `ProtectHome=read-only`), if you like. See the
97 3.2.0 NEWS for the other restrictions that were added compared to 3.1.3.
99 - The memory allocation functions now automatically check for a failure and
100 die when out of memory. This eliminated some caller-side check-and-die
101 code and added some missing sanity-checking of allocations.
103 - Put optimizations into their own list in the `--version` output.
105 - Improved the man page a bit more.
107 ### PACKAGING RELATED:
109 - Prepared the checksum code for an upcoming xxHash release that provides new
110 XXH3 (64-bit) & XXH128 (128-bit) checksum routines. These will not be
111 compiled into rsync until the xxhash v0.8.0 include files are installed on
112 the build host, and that release is a few weeks away at the time this was
113 written. So, if it's now the future and you have packaged and installed
114 xxhash-0.8.0-devel, a fresh rebuild of rsync 3.2.2 will give you the new
115 checksum routines. Just make sure that the new rsync package depends on
118 ### DEVELOPER RELATED:
120 - Moved the version number out of configure.ac into its own version.h file so
121 that we don't need to reconfigure just because the version number changes.
123 - Moved the daemon parameter list into daemon-parm.txt so that an awk script
124 can create the interrelated structs and accessors that loadparm.c needs.
126 ------------------------------------------------------------------------------
129 # NEWS for rsync 3.2.1 (22 Jun 2020)
131 ## Changes in this version:
135 - Fixed a potential build issue with the MD5 assembly-language code by
136 removing some non-portable directives.
138 - Use the preprocessor with the asm file to ensure that if the code is
139 unneeded, it doesn't get built.
141 - Avoid the stack getting set to executable when including the asm code.
143 - Some improvements in the SIMD configure testing to try to avoid build
144 issues, such as avoiding a clang++ core dump when `-g` is combined with
145 `-O2`. Note that clang++ is quite buggy in this area, and it does still
146 crash for some folks, so just use `--disable-simd` if you need to avoid
147 their buggy compiler (since the configure test is apparently not finding
148 all the compilers that will to crash and burn).
150 - Fixed an issue in the md2man script when building from an alternate dir.
152 - Disable `--atimes` on macOS (it apparently just ignores the atime change).
156 - The use of `--backup-dir=STR` now implies `--backup`.
158 - Added `--zl=NUM` as a short-hand for `--compress-level=NUM`.
160 - Added `--early-input=FILE` option that allows the client to send some
161 data to a daemon's (optional) "early exec" script on its stdin.
163 - Mention atimes in the capabilities list that `--version` outputs.
165 - Mention either "default protect-args" or "optional protect-args" in the
166 `--version` capabilities depending on how rsync was configured.
168 - Some info on optimizations is now elided from the `--version` capabilities
169 since they aren't really user-facing capabilities. You can still see the
170 info (plus the status of a couple extra optimizations) by repeating the
171 `--version` option (e.g. `-VV`).
173 - Updated various URLs to be https instead of http.
175 - Some documentation improvements.
177 ### PACKAGING RELATED:
179 - If you had to use `--disable-simd` for 3.2.0, you might want to try removing
180 that and see if it will succeed or auto-disable. Some buggy clang++
181 compilers are still not auto disabled, though.
183 - The MD5 asm code is now under its own configure flag (not shared with the
184 SIMD setting), so if you have any issues compiling it, re-run configure with
187 - Merged the OLDNEWS.md file into NEWS.md.
189 ------------------------------------------------------------------------------
192 # NEWS for rsync 3.2.0 (19 Jun 2020)
194 ## Changes in this version:
198 - Avoid a potential out-of-bounds read in daemon mode if argc can be made to
201 - Fix the default list of skip-compress files for non-daemon transfers.
203 - Fix xattr filter rules losing an 'x' attribute in a non-local transfer.
205 - Avoid an error when a check for a potential fuzzy file happens to reference
208 - Make the atomic-rsync helper script have a more consistent error-exit.
210 - Make sure that a signal handler's use of exit_cleanup() calls `_exit()`
213 - Various zlib fixes, including security fixes for CVE-2016-9843,
214 CVE-2016-9842, CVE-2016-9841, and CVE-2016-9840.
216 - Fixed an issue with `--remove-source-files` not removing a source symlink
217 when combined with `--copy-links`.
219 - Fixed a bug where the daemon would fail to write early fatal error messages
220 to the client, such as refused or unknown command-line options.
222 - Fixed the block-size validation logic when dealing with older protocols.
224 - Some rrsync fixes and enhancements to handle the latest options.
226 - Fixed a problem with the `--link-dest`|`--copy-dest` code when `--xattrs`
227 was specified along with multiple alternate-destination directories (it
228 could possibly choose a bad file match while trying to find a better xattr
231 - Fixed a couple bugs in the handling of files with the `--sparse` option.
233 - Fixed a bug in the writing of the batch.sh file (w/`--write-batch`) when the
234 source & destination args were not last on the command-line.
236 - Avoid a hang when an overabundance of messages clogs up all the I/O buffers.
238 - Fixed a mismatch in the RSYNC_PID values put into the environment of
239 `pre-xfer exec` and a `post-xfer exec`.
241 - Fixed a crash in the `--iconv` code.
243 - Fixed a rare crash in the popt_unalias() code.
247 - The default systemd config was made stricter by default. For instance,
248 `ProtectHome=on` (which hides content in /root and /home/USER dirs),
249 `ProtectSystem=full` (which makes /usr, /boot, & /etc dirs read-only), and
250 `PrivateDevices=on` (which hides devices). You can override any of these
251 using the standard `systemctl edit rsync` and add one or more directives
252 under a `[Service]` heading (and restart the rsync service).
254 - Various checksum enhancements, including the optional use of openssl's MD4 &
255 MD5 checksum algorithms, some x86-64 optimizations for the rolling checksum,
256 some x86-64 optimizations for the (non-openssl) MD5 checksum, the addition
257 of xxHash checksum support, and a negotiation heuristic that ensures that it
258 is easier to add new checksum algorithms in the future. The environment
259 variable `RSYNC_CHECKSUM_LIST` can be used to customize the preference order
260 of the negotiation, or use `--checksum-choice` (`--cc`) to force a choice.
262 - Various compression enhancements, including the addition of zstd and lz4
263 compression algorithms and a negotiation heuristic that picks the best
264 compression option supported by both sides. The environment variable
265 `RSYNC_COMPRESS_LIST` can be used to customize the preference order of the
266 negotiation, or use `--compress-choice` (`--zc`) to force a choice.
268 - Added a `--debug=NSTR` option that outputs details of the new negotiation
269 strings (for checksums and compression). The first level just outputs the
270 result of each negotiation on the client, level 2 outputs the values of the
271 strings that were sent to and received from the server, and level 3 outputs
272 all those values on the server side too (when the server was given the debug
275 - The `--debug=OPTS` command-line option is no longer auto-forwarded to the
276 remote rsync which allows for the client and server to have different levels
277 of debug specified. This also allows for newer debug options to be
278 specified, such as using `--debug=NSTR` to see the negotiated hash result,
279 without having the command fail if the server version is too old to handle
280 that debug item. Use `-M--debug=OPTS` to send the options to the remote side.
282 - Added the `--atimes` option based on the long-standing patch (just with some
283 fixes that the patch has been needing).
285 - Added `--open-noatime` option to open files using `O_NOATIME`.
287 - Added the `--write-devices` option based on the long-standing patch.
289 - Added openssl & preliminary gnutls support to the rsync-ssl script, which is
290 now installed by default. This was unified with the old stunnel-rsync
291 helper script to simplify packaging. Note that the script accepts the use
292 of `--type=gnutls` for gnutls testing, but does not look for gnutls-cli on
293 the path yet. The use of `--type=gnutls` will not work right until
294 gnutls-cli no longer drops data.
296 - Rsync was enhanced to set the `RSYNC_PORT` environment variable when running
297 a daemon-over-rsh script. Its value is the user-specified port number (set
298 via `--port` or an rsync:// URL) or 0 if the user didn't override the port.
300 - Added the `proxy protocol` daemon parameter that allows your rsyncd to know
301 the real remote IP when it is setup behind a proxy.
303 - Added negated matching to the daemon's `refuse options` setting by using
304 match strings that start with a `!` (such as `!compress*`). This lets you
305 refuse all options except for a particular approved list, for example. It
306 also lets rsync refuse certain options by default (such as `write-devices`)
307 while allowing the config to override that, as desired.
309 - Added the `early exec` daemon parameter that runs a script before the
310 transfer parameters are known, allowing some early setup based on module
313 - Added status output in response to a signal (via both SIGINFO & SIGVTALRM).
315 - Added `--copy-as=USER` option to give some extra security to root-run rsync
316 commands into/from untrusted directories (such as backups and restores).
318 - When resuming the transfer of a file in the `--partial-dir`, rsync will now
319 update that partial file in-place instead of creating yet another tmp file
320 copy. This requires both sender & receiver to be at least v3.2.0.
322 - Added support for `RSYNC_SHELL` & `RSYNC_NO_XFER_EXEC` environment variables
323 that affect the early, pre-xfer, and post-xfer exec rsync daemon parameters.
325 - Optimize the `--fuzzy --fuzzy` heuristic to avoid the fuzzy directory scan
326 until all other basis-file options are exhausted (such as `--link-dest`).
328 - Have the daemon log include the normal-exit sent/received stats when the
329 transfer exited with an error when possible (i.e. if it is the sender).
331 - The daemon now locks its pid file (when configured to use one) so that it
332 will not fail to start when the file exists but no daemon is running.
334 - Various man page improvements, including some html representations (that
335 aren't installed by default).
337 - Made `-V` the short option for `--version` and improved its information.
339 - Pass the `-4` or `-6` option to the ssh command, making it easier to type
340 than `--rsh='ssh -4'` (or the `-6` equivalent).
342 - Added example config for rsyncd SSL proxy configs to rsyncd.conf.
344 - More errors messages now mention if the error is coming from the sender or
347 ### PACKAGING RELATED:
349 - Add installed bash script: /usr/bin/rsync-ssl
351 - Add installed man page: /usr/man/man1/rsync-ssl.1
353 - Tweak auxiliary doc file names, such as: README.md, INSTALL.md, & NEWS.md.
355 - The rsync-ssl script wants to run openssl or stunnel4, so consider adding a
356 dependency for one of those options (though it's probably fine to just let
357 it complain about being unable to find the program and let the user decide
358 if they want to install one or the other).
360 - If you packaged rsync + rsync-ssl + rsync-ssl-daemon as separate packages,
361 the rsync-ssl package is now gone (rsync-ssl should be considered to be
362 mainstream now that Samba requires SSL for its rsync daemon).
364 - Add _build_ dependency for liblz4-dev, libxxhash-dev, libzstd-dev, and
365 libssl-dev. These development libraries will give rsync extra compression
366 algorithms, extra checksum algorithms, and allow use of openssl's crypto
367 lib for (potentially) faster MD4/MD5 checksums.
369 - Add _build_ dependency for g++ or clang++ on x86_64 systems to enable the
370 SIMD checksum optimizations.
372 - Add _build_ dependency for _either_ python3-cmarkcfm or python3-commonmark
373 to allow for patching of man pages or building a git release. This is not
374 required for a release-tar build, since it comes with pre-built man pages.
375 Note that cmarkcfm is faster than commonmark, but they generate the same
376 data. The commonmark dependency is easiest to install since it's native
377 python, and can even be installed via `pip3 install --user commonmark` if
378 you want to just install it for the build user.
380 - Remove yodl _build_ dependency (if it was even listed before).
382 ### DEVELOPER RELATED:
384 - Silenced some annoying warnings about major() & minor() by improving an
385 autoconf include-file check.
387 - Converted the man pages from yodl to markdown. They are now processed via a
388 simple python3 script using the cmarkgfm **or** commonmark library. This
389 should make it easier to package rsync, since yodl is rather obscure.
391 - Improved some configure checks to work better with strict C99 compilers.
393 - Some perl building/packaging scripts were recoded into awk and python3.
395 - Some defines in byteorder.h were changed into static inline functions that
396 will help to ensure that the args don't get evaluated multiple times on
397 "careful alignment" hosts.
399 - Some code typos were fixed (as pointed out by a Fossies run).
401 ------------------------------------------------------------------------------
404 # NEWS for rsync 3.1.3 (28 Jan 2018)
406 ## Changes in this version:
410 - Fixed a buffer overrun in the protocol's handling of xattr names and ensure
411 that the received name is null terminated.
413 - Fix an issue with `--protect-args` where the user could specify the arg in the
414 protected-arg list and short-circuit some of the arg-sanitizing code.
418 - Don't output about a new backup dir without appropriate info verbosity.
420 - Fixed some issues with the sort functions in support/rsyncstats script.
422 - Added a way to specify daemon config lists (e.g. users, groups, etc) that
423 contain spaces (see `auth users` in the latest rsyncd.conf manpage).
425 - If a backup fails (e.g. full disk) rsync exits with an error.
427 - Fixed a problem with a doubled `--fuzzy` option combined with `--link-dest`.
429 - Avoid invalid output in the summary if either the start or end time had an
432 - We don't allow a popt alias to affect the `--daemon` or `--server` options.
434 - Fix daemon exclude code to disallow attribute changes in addition to
435 disallowing transfers.
437 - Don't force nanoseconds to match if a non-transferred, non-checksummed file
438 only passed the quick-check w/o comparing nanosecods.
442 - Added the ability for rsync to compare nanosecond times in its file-check
443 comparisons, and added support nanosecond times on Mac OS X.
445 - Added a short-option (`-@`) for `--modify-window`.
447 - Added the `--checksum-choice=NAME[,NAME]` option to choose the checksum
450 - Added hashing of xattr names (with using `-X`) to improve the handling of
451 files with large numbers of xattrs.
453 - Added a way to filter xattr names using include/exclude/filter rules (see
454 the `--xattrs` option in the manpage for details).
456 - Added `daemon chroot|uid|gid` to the daemon config (in addition to the old
457 chroot|uid|gid settings that affect the daemon's transfer process).
459 - Added `syslog tag` to the daemon configuration.
461 - Some manpage improvements.
463 ### DEVELOPER RELATED:
465 - Tweak the `make` output when yodl isn't around to create the man pages.
467 - Changed an obsolete autoconf compile macro.
469 - Support newer yodl versions when converting man pages.
471 ------------------------------------------------------------------------------
474 # NEWS for rsync 3.1.2 (21 Dec 2015)
476 ## Changes in this version:
480 - Make sure that all transferred files use only path names from inside the
481 transfer. This makes it impossible for a malicious sender to try to make the
482 receiver use an unsafe destination path for a transferred file, such as a
487 - Change the checksum seed order in the per-block checksums. This prevents
488 someone from trying to create checksum blocks that match in sum but not
491 - Fixed a with the per-dir filter files (using `-FF`) that could trigger an
494 - Only skip `set_modtime()` on a transferred file if the time is exactly
497 - Don't create an empty backup dir for a transferred file that doesn't exist
500 - Fixed a bug where `--link-dest` and `--xattrs` could cause rsync to exit if
501 a filename had a matching dir of the same name in the alt-dest area.
503 - Allow more than 32 group IDs per user in the daemon's gid=LIST config.
505 - Fix the logging of %b & %c via `--log-file` (daemon logging was already
506 correct, as was `--out-format='%b/%c'`).
508 - Fix erroneous acceptance of `--info=5` & `--debug=5` (an empty flag name is
513 - Added `(DRY RUN)` info to the `--debug=exit` output line.
515 - Use usleep() for our msleep() function if it is available.
517 - Added a few extra long-option names to rrsync script, which will make
520 - Made configure choose to use linux xattrs on netbsd (rather than not
523 - Added `-wo` (write-only) option to rrsync support script.
525 - Misc. manpage tweaks.
527 ### DEVELOPER RELATED:
529 - Fixed a bug with the Makefile's use of `INSTALL_STRIP`.
531 - Improve a test in the suite that could get an erroneous timestamp error.
533 - Tweaks for newer versions of git in the packaging tools.
535 - Improved the m4 generation rules and some autoconf idioms.
537 ------------------------------------------------------------------------------
540 # NEWS for rsync 3.1.1 (22 Jun 2014)
542 ## Changes in this version:
546 - If the receiver gets bogus filenames from the sender (an unexpected leading
547 slash or a `..` infix dir), exit with an error. This prevents a malicious
548 sender from trying to inject filenames that would affect an area outside the
549 destination directories.
551 - Fixed a failure to remove the partial-transfer temp file when interrupted
552 (and rsync is not saving the partial files).
554 - Changed the chown/group/xattr-set order to avoid losing some security-
555 related xattr info (that would get cleared by a chown).
557 - Fixed a bug in the xattr-finding code that could make a non-root-run
558 receiver not able to find some xattr numbers.
560 - Fixed a bug in the early daemon protocol where a timeout failed to be
561 honored (e.g. if the remote side fails to send us the initial protocol
564 - Fixed unintended inclusion of commas in file numbers in the daemon log.
566 - We once again send the 'f' sub-flag (of `-e`) to the server side so it knows
567 that we can handle incremental-recursion directory errors properly in older
570 - Fixed an issue with too-aggressive keep-alive messages causing a problem for
571 older rsync versions early in the transfer.
573 - Fixed an incorrect message about backup-directory-creation when using
574 `--dry-run` and the backup dir is not an absolute path.
576 - Fixed a bug where a failed deletion and/or a failed sender-side removal
577 would not affect the exit code.
579 - Fixed a bug that caused a failure when combining `--delete-missing-args`
580 with `--xattrs` and/or `--acls`.
582 - Fixed a strange `dir_depth` assertion error that was caused by empty-dir
583 removals and/or duplicate files in the transfer.
585 - Fixed a problem with `--info=progress2`'s output stats where rsync would
586 only update the stats at the end of each file's transfer. It now uses the
587 data that is flowing for the current file, making the stats more accurate
590 - Fixed an itemize bug that affected the combo of `--link-dest`, `-X`, and
593 - Fixed a problem with delete messages not appearing in the log file when the
594 user didn't use `--verbose`.
596 - Improve chunked xattr reading for OS X.
598 - Removed an attempted hard-link xattr optimization that was causing a
599 transfer failure. This removal is flagged in the compatibility code, so if a
600 better fix can be discovered, we have a way to flip it on again.
602 - Fixed a bug when the receiver is not configured to be able to hard link
603 symlimks/devices/special-file items but the sender sent some of these items
604 flagged as hard-linked.
606 - We now generate a better error if the buffer overflows in `do_mknod()`.
608 - Fixed a problem reading more than 16 ACLs on some OSes.
610 - Fixed the reading of the secrets file to avoid an infinite wait when the
613 - Fixed a parsing problem in the `--usermap`/`--groupmap` options when using
616 - Switched Cygwin back to using socketpair `pipes` to try to speed it up.
618 - Added knowledge of a few new options to rrsync.
622 - Tweaked the temp-file naming when `--temp-dir=DIR` is used: the temp-file
623 names will not get a '.' prepended.
625 - Added support for a new-compression idiom that does not compress all the
626 matching data in a transfer. This can help rsync to use less cpu when a
627 transfer has a lot of matching data, and also makes rsync compatible with a
628 non-bundled zlib. See the `--new-compress` and `--old-compress` options in
631 - Added the support/rsync-no-vanished wrapper script.
633 - Made configure more prominently mention when we failed to find yodl (in case
634 the user wants to be able to generate manpages from `*.yo` files).
636 - Have manpage mention how a daemon's max-verbosity setting affects info and
637 debug options. Also added more clarification on backslash removals for
638 excludes that contain wildcards.
640 - Have configure check if for the attr lib (for getxattr) for those systems
641 that need to link against it explicitly.
643 - Change the early dir-creation logic to only use that idiom in an
644 inc-recursive copy that is preserving directory times. e.g. using
645 `--omit-dir-times` will avoid these early directories being created.
647 - Fix a bug in `cmp_time()` that would return a wrong result if the 2 times
648 differed by an amount greater than what a `time_t` can hold.
650 ### DEVELOPER RELATED:
652 - We now include an example systemd file (in packaging/systemd).
654 - Tweaked configure to make sure that any intended use of the included popt
655 and/or zlib code is put early in the CFLAGS.
657 ------------------------------------------------------------------------------
660 # NEWS for rsync 3.1.0 (28 Sep 2013)
662 ## Changes in this version:
666 - The protocol number was changed to 31.
670 - Output numbers in 3-digit groups by default (e.g. 1,234,567). See the
671 `--human-readable` option for a way to turn it off. See also the daemon's
672 `log format` parameter and related command-line options (including
673 `--out-format`) for a modifier that can be used to request digit-grouping or
674 human-readable output in log escapes. (Note that log output is unchanged by
677 - The `--list-only` option is now affected by the `--human-readable` setting.
678 It will display digit groupings by default, and unit suffixes if higher
679 levels of readability are requested. Also, the column width for the size
680 output has increased from 11 to 14 characters when human readability is
681 enabled. Use `--no-h` to get the old-style output and column size.
683 - The output of the `--progress` option has changed: the string `xfer` was
684 shortened to `xfr`, and the string `to-check` was shortened to `to-chk`,
685 both designed to make room for the (by default) wider display of file size
686 numbers without making the total line-length longer. Also, when incremental
687 recursion is enabled, the string `ir-chk` will be used instead of `to-chk`
688 up until the incremental-recursion scan is done, letting you know that the
689 value to check and the total value will still be increasing as new files are
692 - Enhanced the `--stats` output: 1) to mention how many files were created
693 (protocol >= 28), 2) to mention how many files were deleted (a new line for
694 protocol 31, but only output when `--delete` is in effect), and 3) to follow
695 the file-count, created-count, and deleted-count with a subcount list that
696 shows the counts by type. The wording of the transferred count has also
697 changed so that it is clearer that it is only a count of regular files.
701 - Fixed a bug in the iconv code when EINVAL or EILSEQ is returned with a full
704 - Fixed some rare bugs in `--iconv` processing that might cause a multibyte
705 character to get translated incorrectly.
707 - Fixed a bogus `vanished file` error if some files were specified with `./`
708 prefixes and others were not.
710 - Fixed a bug in `--sparse` where an extra gap could get inserted after a
713 - Changed the way `--progress` overwrites its prior output in order to make it
714 nearly impossible for the progress to get overwritten by an error.
716 - Improved the propagation of abnormal-exit error messages. This should help
717 the client side to receive errors from the server when it is exiting
718 abnormally, and should also avoid dying with an `connection unexpectedly
719 closed` exit when the closed connection is really expected.
721 - The sender now checks each file it plans to remove to ensure that it hasn't
722 changed from the first stat's info. This helps to avoid losing file data
723 when the user is not using the option in a safe manner.
725 - Fixed a data-duplication bug in the compress option that made compression
726 less efficient. This improves protocol 31 onward, while behaving in a
727 compatible (buggy) manner with older rsync protocols.
729 - When creating a temp-file, rsync is now a bit smarter about it dot-char
730 choices, which can fix a problem on OS X with names that start with `..`.
732 - Rsync now sets a cleanup flag for `--inplace` and `--append` transfers that
733 will flush the write buffer if the transfer aborts. This ensures that more
734 received data gets written out to the disk on an aborted transfer (which is
735 quite helpful on a slow, flaky connection).
737 - The reads that `map_ptr()` now does are aligned on 1K boundaries. This helps
738 some filesystems and/or files that don't like unaligned reads.
740 - Fix an issue in the msleep() function if time jumps backwards.
742 - Fix daemon-server module-name splitting bug where an arg would get split
743 even if `--protect-args` was used.
747 - Added the `--remote-option=OPT` (`-M OPT`) command-line option that is
748 useful for things like sending a remote `--log-file=FILE` or `--fake-super`
751 - Added the `--info=FLAGS` and `--debug=FLAGS` options to allow finer-grained
752 control over what is output. Added an extra type of `--progress` output
753 using `--info=progress2`.
755 - The `--msgs2stderr` option can help with debugging rsync by allowing the
756 debug messages to get output to stderr rather than travel via the socket
759 - Added the `--delete-missing-args` and `--ignore-missing-args` options to
760 either delete or ignore user-specified files on the receiver that are
761 missing on the sender (normally the absence of user-specified files
764 - Added a `T` (terabyte) category to the `--human-readable` size suffixes.
766 - Added the `--usermap`/`--groupmap`/`--chown` options for manipulating file
767 ownership during the copy.
769 - Added the `%C` escape to the log-output handling, which will output the MD5
770 checksum of any transferred file, or all files if `--checksum` was specified
771 (when protocol 30 or above is in effect).
773 - Added the `reverse lookup` parameter to the rsync daemon config file to
774 allow reverse-DNS lookups to be disabled.
776 - Added a forward-DNS lookup for the daemon's hosts allow/deny config. Can be
777 disabled via `forward lookup` parameter (defaults to enabled).
779 - Added a way for more than one group to be specified in the daemon's config
780 file, including a way to specify that you want all of the specified user's
781 groups without having to name them. Also changed the daemon to complain
782 about an inability to set explicitly-specified uid/gid values, even when not
785 - The daemon now tries to send the user the error messages from the pre-xfer
786 exec script when it fails.
788 - Improved the use of alt-dest options into an existing hierarchy of files: If
789 a match is found in an alt-dir, it takes precedence over an existing file.
790 (We'll need to wait for a future version before attribute-changes on
791 otherwise unchanged files are safe when using an existing hierarchy.)
793 - Added per-user authorization options and group-authorization support to the
794 daemon's `auth users` parameter.
796 - Added a way to reference environment variables in a daemon's config file
797 (using %VAR% references).
799 - When replacing a non-dir with a symlink/hard-link/device/special-file, the
800 update should now be done in an atomic manner.
802 - Avoid re-sending xattr info for hard-linked files w/the same xattrs
805 - The backup code was improved to use better logic maintaining the backup
806 directory hierarchy. Also, when a file is being backed up, rsync tries to
807 hard-link it into place so that the upcoming replacement of the destination
808 file will be atomic (for the normal, non-inplace logic).
810 - Added the ability to synchronize nano-second modified times.
812 - Added a few more default suffixes for the `dont compress` settings.
814 - Added the checking of the `RSYNC_PROTECT_ARGS` environment variable to allow
815 the default for the `--protect-args` command-line option to be overridden.
817 - Added the `--preallocate` command-line option.
819 - Allow `--password-file=-` to read the password from stdin (filename `-`).
821 - Rsync now comes packaged with an rsync-ssl helper script that can be used to
822 contact a remote rsync daemon using a piped-stunnel command. It also
823 includes an stunnel config file to run the server side to support ssl daemon
824 connections. See the packaging/lsb/rsync.spec file for one way to package
825 the resulting files. (Suggestions for how to make this even easier to
826 install & use are welcomed.)
828 - Improved the speed of some `--inplace` updates when there are lots of
829 identical checksum blocks that end up being unusable.
831 - Added the `--outbuf=N|L|B` option for choosing the output buffering.
833 - Repeating the `--fuzzy` option now causes the code to look for fuzzy matches
834 inside alt-dest directories too.
836 - The `--chmod` option now supports numeric modes, e.g. `--chmod=644,D755`
838 - Added some Solaris xattr code.
840 - Made an rsync daemon (the listening process) exit with a 0 status when it
841 was signaled to die. This helps launchd.
843 - Improved the `RSYNC_*` environment variables for the pre-xfer exec script:
844 when a daemon is sent multiple request args, they are now joined into a
845 single return value (separated by spaces) so that the `RSYNC_REQUEST`
846 environment variable is accurate for any `pre-xfer exec`. The values in
847 `RSYNC_ARG#` vars are no longer truncated at the `.` arg (prior to the
848 request dirs/files), so that all the requested values are also listed
849 (separately) in `RSYNC_ARG#` variables.
853 - Added an `instant-rsyncd` script to the support directory, which makes it
854 easy to configure a simple rsync daemon in the current directory.
856 - Added the `mapfrom` and `mapto` scripts to the support directory, which
857 makes it easier to do user/group mapping in a local transfer based on
858 passwd/group files from another machine.
860 - There's a new, improved version of the lsh script in the support dir: it's
861 written in perl and supports `-u` without resorting to using sudo (when run
862 as root). The old shell version is now named lsh.sh.
864 - There is a helper script named rsync-slash-strip in the support directory
865 for anyone that wants to change the way rsync handles args with trailing
866 slashes. (e.g. arg/ would get stripped to arg while arg/. would turn into
871 - The I/O code was rewritten to be simpler and do bigger buffered reads over
872 the socket. The I/O between the receiver and the generator was changed to be
873 standard multiplexed-I/O (like that over the socket).
875 - The sender tries to use any dead time while the generator is looking for
876 files to transfer in order to do sender-side directory scanning in a more
879 - A daemon can now inform a client about a daemon-configured timeout value so
880 that the client can assist in the keep-alive activity (protocol 31).
882 - The filter code received some refactoring to make it more extendible, to
883 read better, and do better sanity checking.
885 - Really big numbers are now output using our own big-num routine rather than
886 casting them to a double and using a %.0f conversion.
888 - The `pool_alloc` library has received some minor improvements in alignment
891 - Added `init_stat_x()` function to avoid duplication of acl/xattr init code.
893 - The included zlib was upgraded from 1.2.3 to 1.2.8.
895 - Rsync can now be compiled to use an unmodified zlib library instead of the
896 tweaked one that is included with rsync. This will eventually become the
897 default, at which point we'll start the countdown to removing the included
898 zlib. Until then, feel free to configure using:
900 ./configure `--with-included-zlib=no`
902 ### DEVELOPER RELATED:
904 - Added more conditional debug output.
906 - Fixed some build issues for android and minix.

911 # NEWS for rsync 3.0.9 (23 Sep 2011)
913 ## Changes in this version:
917 - Fix a crash bug in checksum scanning when `--inplace` is used.
919 - Fix a hang if a hard-linked file cannot be opened by the sender (e.g. if it
920 has no read permission).
922 - Fix preservation of a symlink's system xattrs (e.g. selinux) on Linux.
924 - Fix a memory leak in the xattr code.
926 - Fixed a bug with `--delete-excluded` when a filter merge file has a rule
927 that specifies a receiver-only side restriction.
929 - Fix a bug with the modifying of unwritable directories.
931 - Fix `--fake-super`'s interaction with `--link-dest` same-file comparisons.
933 - Fix the updating of the `curr_dir` buffer to avoid a duplicate slash.
935 - Fix the directory permissions on an implied dot-dir when using `--relative`
936 (e.g. /outside/path/././send/path).
938 - Fixed some too-long sleeping instances when using `--bwlimit`.
940 - Fixed when symlink ownership difference-checking gets compiled into
943 - Improved the socket-error reporting when multiple protocols fail.
945 - Fixed a case where a socket error could reference just-freed memory.
947 - Failing to use a password file that was specified on the command-line is now
950 - Fix the non-root updating of directories that don't have the read and/or
953 - Make daemon-excluded file errors more error-like.
955 - Fix a compilation issue on older C compilers (due to a misplaced var
958 - Make configure avoid finding socketpair on cygwin.
960 - Avoid trying to reference `SO_BROADCAST` if the OS doesn't support it.
962 - Fix some issues with the post-processing of the man pages.
964 - Fixed the user home-dir handling in the support/lsh script.
966 - Some minor manpage improvements.
968 ------------------------------------------------------------------------------
971 # NEWS for rsync 3.0.8 (26 Mar 2011)
973 ## Changes in this version:
977 - Fixed two buffer-overflow issues: one where a directory path that is exactly
978 MAXPATHLEN was not handled correctly, and one handling a `--backup-dir` that
979 is extra extra large.
981 - Fixed a data-corruption issue when preserving hard-links without preserving
982 file ownership, and doing deletions either before or during the transfer
983 (CVE-2011-1097). This fixes some assert errors in the hard-linking code, and
984 some potential failed checksums (via `-c`) that should have matched.
986 - Fixed a potential crash when an rsync daemon has a filter/exclude list and
987 the transfer is using ACLs or xattrs.
989 - Fixed a hang if a really large file is being processed by an rsync that
990 can't handle 64-bit numbers. Rsync will now complain about the file being
993 - For devices and special files, we now avoid gathering useless ACL and/or
994 xattr information for files that aren't being copied. (The un-copied files
995 are still put into the file list, but there's no need to gather data that is
996 not going to be used.) This ensures that if the user uses `--no-D`, that
997 rsync can't possibly complain about being unable to gather extended
998 information from special files that are in the file list (but not in the
1001 - Properly handle requesting remote filenames that start with a dash. This
1002 avoids a potential error where a filename could be interpreted as a (usually
1005 - Fixed a bug in the comparing of upper-case letters in file suffixes for
1008 - If an rsync daemon has a module configured without a path setting, rsync
1009 will now disallow access to that module.
1011 - If the destination arg is an empty string, it will be treated as a reference
1012 to the current directory (as 2.x used to do).
1014 - If rsync was compiled with a newer time-setting function (such as lutimes),
1015 rsync will fall-back to an older function (such as utimes) on a system where
1016 the newer function is not around. This helps to make the rsync binary more
1017 portable in mixed-OS-release situations.
1019 - Fixed a batch-file writing bug that would not write out the full set of
1020 compatibility flags that the transfer was using. This fixes a potential
1021 protocol problem for a batch file that contains a sender-side I/O error: it
1022 would have been sent in a way that the batch-reader wasn't expecting.
1024 - Some improvements to the hard-linking code to ensure that device-number
1025 hashing is working right, and to supply more information if the hard-link
1028 - The `--inplace` code was improved to not search for an impossible checksum
1029 position. The quadruple-verbose chunk[N] message will now mention when an
1030 inplace chunk was handled by a seek rather than a read+write.
1032 - Improved ACL mask handling, e.g. for Solaris.
1034 - Fixed a bug that prevented `--numeric-ids` from disabling the translation of
1035 user/group IDs for ACLs.
1037 - Fixed an issue where an xattr and/or ACL transfer that used an alt-dest
1038 option (e.g. `--link-dest`) could output an error trying to itemize the
1039 changes against the alt-dest directory's xattr/ACL info but was instead
1040 trying to access the not-yet-existing new destination directory.
1042 - Improved xattr system-error messages to mention the full path to the file.
1044 - The `--link-dest` checking for identical symlinks now avoids considering
1045 attribute differences that cannot be changed on the receiver.
1047 - Avoid trying to read/write xattrs on certain file types for certain OSes.
1048 Improved configure to set `NO_SYMLINK_XATTRS`, `NO_DEVICE_XATTRS`, and/or
1049 `NO_SPECIAL_XATTRS` defines in config.h.
1051 - Improved the unsafe-symlink errors messages.
1053 - Fixed a bug setting xattrs on new files that aren't user writable.
1055 - Avoid re-setting xattrs on a hard-linked file w/the same xattrs.
1057 - Fixed a bug with `--fake-super` when copying files and dirs that aren't user
1060 - Fixed a bug where a sparse file could have its last sparse block turned into
1061 a real block when rsync sets the file size (requires ftruncate).
1063 - If a temp-file name is too long, rsync now avoids truncating the name in the
1064 middle of adjacent high-bit characters. This prevents a potential filename
1065 error if the filesystem doesn't allow a name to contain an invalid
1066 multi-byte sequence.
1068 - If a muli-protocol socket connection fails (i.e., when contacting a daemon),
1069 we now report all the failures, not just the last one. This avoids losing a
1070 relevant error (e.g. an IPv4 connection-refused error) that happened before
1071 the final error (e.g. an IPv6 protocol-not-supported error).
1073 - Generate a transfer error if we try to call chown with a `-1` for a uid or a
1074 gid (which is not settable).
1076 - Fixed the working of `--force` when used with `--one-file-system`.
1078 - Fix the popt arg parsing so that an option that doesn't take an arg will
1079 reject an attempt to supply one (can configure `--with-included-popt` if
1080 your system's popt library doesn't yet have this fix).
1082 - A couple minor option tweaks to the support/rrsync script, and also some
1083 regex changes that make vim highlighting happier.
1085 - Fixed some issues in the support/mnt-excl script.
1087 - Various manpage improvements.
1091 - Added `.hg/` to the default cvs excludes (see `-C` & `--cvs-exclude`).
1093 ### DEVELOPER RELATED:
1095 - Use lchmod() whenever it is available (not just on symlinks).
1097 - A couple fixes to the `socketpair_tcp()` routine.
1099 - Updated the helper scripts in the packaging subdirectory.
1101 - Renamed configure.in to configure.ac.
1103 - Fixed configure's checking for iconv routines for newer OS X versions.
1105 - Fixed the testsuite/xattrs.test script on OS X.

1110 # NEWS for rsync 3.0.7 (31 Dec 2009)
1112 ## Changes in this version:
1116 - Fixed a bogus free when using `--xattrs` with `--backup`.
1118 - Avoid an error when `--dry-run` was trying to stat a prior hard-link file
1119 that hasn't really been created.
1121 - Fixed a problem with `--compress` (`-z`) where the receiving side could
1122 return the error "inflate (token) returned -5".
1124 - Fixed a bug where `--delete-during` could delete in a directory before it
1125 noticed that the sending side sent an I/O error for that directory (both
1126 sides of the transfer must be at least 3.0.7).
1128 - Improved `--skip-compress`'s error handling of bad character-sets and got
1129 rid of a lingering debug fprintf().
1131 - Fixed the daemon's conveyance of `io_error` value from the sender.
1133 - An rsync daemon use seteuid() (when available) if it used setuid().
1135 - Get the permissions right on a `--fake-super` transferred directory that
1136 needs more owner permissions to emulate root behavior.
1138 - An absolute-path filter rule (i.e. with a '/' modifier) no longer loses its
1139 modifier when sending the filter rules to the remote rsync.
1141 - Improved the "--delete does not work without -r or -d" message.
1143 - Improved rsync's handling of `--timeout` to avoid a weird timeout case where
1144 the sender could timeout even though it has recently written data to the
1145 socket (but hasn't read data recently, due to the writing).
1147 - Some misc manpage improvements.
1149 - Fixed the chmod-temp-dir testsuite on a system without /var/tmp.
1151 - Make sure that a timeout specified in the daemon's config is used as a
1152 maximum timeout value when the user also specifies a timeout.
1154 - Improved the error-exit reporting when rsync gets an error trying to cleanup
1155 after an error: the initial error is reported.
1157 - Improved configure's detection of IPv6 for solaris and cygwin.
1159 - The AIX sysacls routines will now return ENOSYS if ENOTSUP is missing.
1161 - Made our (only used if missing) getaddrinfo() routine use `inet_pton()`
1162 (which we also provide) instead of `inet_aton()`.
1164 - The exit-related debug messages now mention the program's role so it is
1165 clear who output what message.
1167 ### DEVELOPER RELATED:
1169 - Got rid of type-punned compiler warnings output by newer gcc versions.
1171 - The Makefile now ensures that proto.h will be rebuilt if config.h changes.
1173 - The testsuite no longer uses `id -u`, so it works better on solaris.

1178 # NEWS for rsync 3.0.6 (8 May 2009)
1180 ## Changes in this version:
1184 - Fixed a `--read-batch` hang when rsync is reading a batch file that was
1185 created from an incremental-recursion transfer.
1187 - Fixed the daemon's socket code to handle the simultaneous arrival of
1188 multiple connections.
1190 - Fix `--safe-links`/`--copy-unsafe-links` to properly handle symlinks that
1191 have consecutive slashes in the value.
1193 - Fixed the parsing of an `[IPv6_LITERAL_ADDR]` when a USER@ is prefixed.
1195 - The sender now skips a (bogus) symlink that has a 0-length value, which
1196 avoids a transfer error in the receiver.
1198 - Fixed a case where the sender could die with a tag-0 error if there was an
1199 I/O during the sending of the file list.
1201 - Fixed the rrsync script to avoid a server-side problem when `-e` is at the
1202 start of the short options.
1204 - Fixed a problem where a vanished directory could turn into an exit code 23
1205 instead of the proper exit code 24.
1207 - Fixed the `--iconv` conversion of symlinks when doing a local copy.
1209 - Fixed a problem where `--one-file-system` was not stopping deletions on the
1210 receiving side when a mount-point directory did not match a directory in the
1213 - Fixed the dropping of an ACL mask when no named ACL values were present.
1215 - Fixed an ACL/xattr corruption issue where the `--backup` option could cause
1216 rsync to associate the wrong ACL/xattr information with received files.
1218 - Fixed the use of `--xattrs` with `--only-write-batch`.
1220 - Fixed the use of `--dry-run` with `--read-batch`.
1222 - Fixed configure's erroneous use of target.
1224 - Fixed configure's `--disable-debug` option.
1226 - Fixed a run-time issue for systems that can't find `iconv_open()` by adding
1227 the `--disable-iconv-open` configure option.
1229 - Complain and die if the user tries to combine `--remove-source-files` (or
1230 the deprecated `--remove-sent-files`) with `--read-batch`.
1232 - Fixed an failure transferring special files from Solaris to Linux.

1237 # NEWS for rsync 3.0.5 (28 Dec 2008)
1239 ## Changes in this version:
1243 - Initialize xattr data in a couple spots in the hlink code, which avoids a
1244 crash when the xattr pointer's memory happens to start out non-zero. Also
1245 fixed the itemizing of an alt-dest file's xattrs when hard-linking.
1247 - Don't send a bogus `-` option to an older server if there were no short
1250 - Fixed skipping of unneeded updates in a batch file when incremental
1251 recursion is active. Added a test for this. Made batch-mode handle `redo`
1252 files properly (and without hanging).
1254 - Fix the %P logfile escape when the daemon logs from inside a chroot.
1256 - Fixed the use of `-s` (`--protect-args`) when used with a remote source or
1257 destination that had an empty path (e.g. `host:`). Also fixed a problem when
1258 `-s` was used when accessing a daemon via a remote-shell.
1260 - Fixed the use of a dot-dir path (e.g. foo/./bar) inside a `--files-from`
1261 file when the root of the transfer isn't the current directory.
1263 - Fixed a bug with `-K --delete` removing symlinks to directories when
1264 incremental recursion is active.
1266 - Fixed a hard to trigger hang when using `--remove-source-files`.
1268 - Got rid of an annoying delay when accessing a daemon via a remote-shell.
1270 - Properly ignore (superfluous) source args on a `--read-batch` command.
1272 - Improved the manpage's description of the `*` wildcard to remove the
1273 confusing `non-empty` qualifier.
1275 - Fixed reverse lookups in the compatibility-library version of getnameinfo().
1277 - Fixed a bug when using `--sparse` on a sparse file that has over 2GB of
1278 consecutive sparse data.
1280 - Avoid a hang when using at least 3 `--verbose` options on a transfer with a
1281 client sender (which includes local copying).
1283 - Fixed a problem with `--delete-delay` reporting an error when it was ready
1284 to remove a directory that was now gone.
1286 - Got rid of a bunch of `warn_unused_result` compiler warnings.
1288 - If an ftruncate() on a received file fails, it now causes a partial-
1291 - Allow a path with a leading `//` to be preserved (CYGWIN only).

1302 # NEWS for rsync 3.0.4 (6 Sep 2008)
1304 ## Changes in this version:
1308 - Fixed a bug in the hard-linking code where it would sometimes try to
1309 allocate 0 bytes of memory (which fails on some OSes, such as AIX).
1311 - Fixed the hard-linking of files from a device that has a device number of 0
1312 (which seems to be a common device number on NetBSD).
1314 - Fixed the handling of a `--partial-dir` that cannot be created. This
1315 particularly impacts the `--delay-updates` option (since the files cannot be
1316 delayed without a partial-dir), and was potentially destructive if the
1317 `--remove-source-files` was also specified.
1319 - Fixed a couple issues in the `--fake-super` handling of xattrs when the
1320 destination files have root-level attributes (e.g. selinux values) that a
1321 non-root copy can't affect.
1323 - Improved the keep-alive check in the generator to fire consistently in
1324 incremental-recursion mode when `--timeout` is enabled.
1326 - The `--iconv` option now converts the content of a symlink too, instead of
1327 leaving it in the wrong character-set (requires 3.0.4 on both sides of the
1330 - When using `--iconv`, if a filename fails to convert on the receiving side,
1331 this no longer makes deletions in the root-dir of the transfer fail silently
1332 (the user now gets a warning about deletions being disabled due to IO error
1333 as long as `--ignore-errors` was not specified).
1335 - When using `--iconv`, if a server-side receiver can't convert a filename,
1336 the error message sent back to the client no longer mangles the name with
1337 the wrong charset conversion.
1339 - Fixed a potential alignment issue in the IRIX ACL code when allocating the
1340 initial `struct acl` object. Also, cast mallocs to avoid warnings.
1342 - Changed some errors that were going to stdout to go to stderr.
1344 - Made `human_num()` and `human_dnum()` able to output a negative number
1345 (rather than outputting a cryptic string of punctuation).
1349 - Rsync will avoid sending an `-e` option to the server if an older protocol
1350 is requested (and thus the option would not be useful). This lets the user
1351 specify the `--protocol=29` option to access an overly-restrictive server
1352 that is rejecting the protocol-30 use of `-e` to the server.
1354 - Improved the message output for an `RERR_PARTIAL` exit.
1356 ### DEVELOPER RELATED:
1358 - The Makefile will not halt for just a timestamp change on the Makefile or
1359 the configure files, only for actual changes in content.
1361 - Changed some commands in the testsuite's xattrs.test that called `rsync`
1362 instead of `$RSYNC`.
1364 - Enhanced the release scripts to be able to handle a branch release and to do
1365 even more consistency checks on the files.

1370 # NEWS for rsync 3.0.3 (29 Jun 2008)
1372 ## Changes in this version:
1376 - Fixed a wildcard matching problem in the daemon when a module has `use
1379 - Fixed a crash bug in the hard-link code.
1381 - Fixed the sending of xattr directory information when the code finds a
1382 `--link-dest` or `--copy-dest` directory with unchanged xattrs -- the
1383 destination directory now gets these unchanged xattrs properly applied.
1385 - Fixed an xattr-sending glitch that could cause an `Internal abbrev` error.
1387 - Fixed the combination of `--xattrs` and `--backup`.
1389 - The generator no longer allows a '.' dir to be excluded by a daemon- exclude
1392 - Fixed deletion handling when copying a single, empty directory (with no
1393 files) to a differently named, non-existent directory.
1395 - Fixed the conversion of spaces into dashes in the %M log escape.
1397 - Fixed several places in the code that were not returning the right errno
1398 when a function failed.
1400 - Fixed the backing up of a device or special file into a backup dir.
1402 - Moved the setting of the socket options prior to the connect().
1404 - If rsync exits in the middle of a `--progress` output, it now outputs a
1405 newline to help prevent the progress line from being overwritten.
1407 - Fixed a problem with how a destination path with a trailing slash or a
1408 trailing dot-dir was compared against the daemon excludes.
1410 - Fixed the sending of large (size > 16GB) files when talking to an older
1411 rsync (protocols < 30): we now use a compatible block size limit.
1413 - If a file's length is so huge that we overflow a checksum buffer count (i.e.
1414 several hundred TB), warn the user and avoid sending an invalid checksum
1415 struct over the wire.
1417 - If a source arg is excluded, `--relative` no longer adds the excluded arg's
1418 implied dirs to the transfer. This fix also made the exclude check happen in
1419 the better place in the sending code.
1421 - Use the `overflow_exit()` function for overflows, not `out_of_memory()`.
1423 - Improved the code to better handle a system that has only 32-bit file
1428 - The rsyncd.conf manpage now consistently refers to the parameters in the
1429 daemon config file as `parameters`.
1431 - The description of the `--inplace` option was improved.
1435 - Added a new script in the support directory, deny-rsync, which allows an
1436 admin to (temporarily) replace the rsync command with a script that sends an
1437 error message to the remote client via the rsync protocol.
1439 ### DEVELOPER RELATED:
1441 - Fixed a testcase failure if the tests are run as root and made some
1442 compatibility improvements.
1444 - Improved the daemon tests, including checking module comments, the listing
1445 of files, and the ensuring that daemon excludes can't affect a dot-dir arg.
1447 - Improved some build rules for those that build in a separate directory from
1448 the source, including better install rules for the man pages, and the fixing
1449 of a proto.h-tstamp rule that could make the binaries get rebuild without
1452 - Improved the testsuite to work around a problem with some utilities (e.g. cp
1453 -p & touch -r) rounding sub-second timestamps.
1455 - Ensure that the early patches don't cause any generated-file hunks to
1456 bleed-over into patches that follow.

1483 # NEWS for rsync 3.0.1 (3 Apr 2008)
1485 ## Changes in this version:
1487 ### NOTABLE CHANGES IN BEHAVIOR:
1489 - Added the 'c'-flag to the itemizing of non-regular files so that the
1490 itemized output doesn't get hidden if there were no attribute changes, and
1491 also so that the itemizing of a `--copy-links` run will distinguish between
1492 copying an identical non-regular file and the creation of a revised version
1493 with a new value (e.g. a changed symlink referent, a new device number,
1498 - Fixed a crash bug when a single-use rsync daemon (via remote shell) was run
1499 without specifying a `--config=FILE` option.
1501 - Fixed a crash when backing up a directory that has a default ACL.
1503 - Fixed a bug in the handling of xattr values that could cause rsync to not
1504 think that a file's extended attributes are up-to-date.
1506 - Fixed the working of `--fake-super` with `--link-dest` and `--xattrs`.
1508 - Fixed a hang when combining `--dry-run` with `--remove-source-files`.
1510 - Fixed a bug with `--iconv`'s handling of files that cannot be converted: a
1511 failed name can no longer cause a transfer failure.
1513 - Fixed the building of the rounding.h file on systems that need custom
1514 CPPFLAGS to be used. Also improved the error reporting if the building of
1517 - Fixed the use of the `--protect-args` (`-s`) option when talking to a
1520 - Fixed the `--ignore-existing` option's protection of files on the receiver
1521 that are non-regular files on the sender (e.g. if a symlink or a dir on the
1522 sender is trying to replace a file on the receiver). The reverse protection
1523 (protecting a dir/symlink/device from being replaced by a file) was already
1526 - Fixed an assert failure if `--hard-links` is combined with an option that
1527 can skip a file in a set of hard-linked files (i.e. `--ignore-existing`,
1528 `--append`, etc.), without skipping all the files in the set.
1530 - Avoid setting the modify time on a directory that already has the right
1531 modify time set. This avoids tweaking the dir's ctime.
1533 - Improved the daemon-exclude handling to do a better job of applying the
1534 exclude rules to path entries. It also sends the user an error just as if
1535 the files were actually missing (instead of silently ignoring the user's
1536 args), and avoids sending the user the filter-action messages for these
1537 non-user-initiated rules.
1539 - Fixed some glitches with the dry-run code's missing-directory handling,
1540 including a problem when combined with `--fuzzy`.
1542 - Fixed some glitches with the skipped-directory handling.
1544 - Fixed the 'T'-flag itemizing of symlinks when `--time` isn't preserved.
1546 - Fixed a glitch in the itemizing of permissions with the `-E` option.
1548 - The `--append` option's restricting of transfers to those that add data no
1549 longer prevents the updating of non-content changes to otherwise up-to- date
1550 files (i.e. those with the same content but differing permissions,
1551 ownership, xattrs, etc.).
1553 - Don't allow `--fake-super` to be specified with `-XX` (double `--xattrs`)
1554 because the options conflict. If a daemon has `fake super` enabled, it
1555 automatically downgrades a `-XX` request to `-X`.
1557 - Fixed a couple bugs in the parsing of daemon-config excludes that could make
1558 a floating exclude rule get treated as matching an absolute path.
1560 - A daemon doesn't try to auto-refuse the `iconv` option if iconv-support
1561 wasn't compiled in to the daemon (avoiding a warning in the logs).
1563 - Fixed the inclusion of per-dir merge files from implied dirs.
1565 - Fixed the support/rrsync script to work with the latest options that rsync
1566 sends (including its flag-specifying use of `-e` to the server).
1570 - Added the `--old-dirs` (`--old-d`) option to make it easier for a user to
1571 ask for file-listings with older rsync versions (this is easier than having
1572 to type `-r --exclude='/*/*'` manually).
1574 - When getting an error while asking an older rsync daemon for a file listing,
1575 rsync will try to notice if the error is a rejection of the `--dirs` (`-d`)
1576 option and let the user know how to work around the issue.
1578 - Added a few more `--no-OPTION` overrides.
1580 - Improved the documentation of the `--append` option.
1582 - Improved the documentation of the filter/exclude/include daemon parameters.
1586 - Fixed a couple minor bugs in the included popt library (ones which I sent to
1587 the official popt project for inclusion in the 1.14 release).
1589 - Fixed a stat() call that should have been `do_stat()` so that the proper
1590 normal/64-bit stat() function gets called. (Was in an area that should not
1591 have caused problems, though.)
1593 - Changed the file-glob code to do a directory scan without using the `glob`
1594 and `glob.h`. This lets us do the globbing with less memory churn, and also
1595 avoid adding daemon-excluded items to the returned args.
1597 ### DEVELOPER RELATED:
1599 - The configure script tries to get the user's compiler to not warn about
1600 unused function parameters if the build is not including one or more of the
1601 ACL/xattrs/iconv features.
1603 - The configure script now has better checks for figuring out if the included
1604 popt code should be used or not.
1606 - Fixed two testsuite glitches: avoid a failure if someone's `cd` command
1607 outputs the current directory when cd-ing to a relative path, and made the
1608 itemized test query how rsync was built to determine if it should expect
1609 hard-linked symlinks or not.
1611 - Updated the testsuite to verify that various bug fixes remain fixed.
1613 - The RPM spec file was updated to have: (1) comments for how to use the
1614 rsync-patch tar file, and (2) an /etc/xinetd.d/rsync file.
1616 - Updated the build scripts to work with a revised FTP directory structure.

1621 # NEWS for rsync 3.0.0 (1 Mar 2008)
1623 ## Changes in this version:
1625 ### PROTOCOL NUMBER:
1627 - The protocol number was changed to 30.
1629 ### NOTABLE CHANGES IN BEHAVIOR:
1631 - The handling of implied directories when using `--relative` has changed to
1632 send them as directories (e.g. no implied dir is ever sent as a symlink).
1633 This avoids unexpected behavior and should not adversely affect most people.
1634 If you're one of those rare individuals who relied upon having an implied
1635 dir be duplicated as a symlink, you should specify the transfer of the
1636 symlink and the transfer of the referent directory as separate args. (See
1637 also `--keep-dirlinks` and `--no-implied-dirs`.) Also, exclude rules no
1638 longer have a partial effect on implied dirs.
1640 - Requesting a remote file-listing without specifying `-r` (`--recursive`) now
1641 sends the `-d` (`--dirs`) option to the remote rsync rather than sending
1642 `-r` along with an extra exclude of `/*/*`. If the remote rsync does not
1643 understand the `-d` option (i.e. it is 2.6.3 or older), you will need to
1644 either turn off `-d` (`--no-d`), or specify `-r --exclude='/*/*'` manually.
1646 - In `--dry-run` mode, the last line of the verbose summary text is output
1647 with a "(DRY RUN)" suffix to help remind you that no updates were made.
1648 Similarly, `--only-write-batch` outputs `(BATCH ONLY)`.
1650 - A writable rsync daemon with `use chroot` disabled now defaults to a
1651 symlink-munging behavior designed to make symlinks safer while also allowing
1652 absolute symlinks to be stored and retrieved. This also has the effect of
1653 making symlinks unusable while they're in the daemon's hierarchy. See the
1654 daemon's `munge symlinks` parameter for details.
1656 - Starting up an extra copy of an rsync daemon will not clobber the pidfile
1657 for the running daemon -- if the pidfile exists, the new daemon will exit
1658 with an error. This means that your wrapper script that starts the rsync
1659 daemon should be made to handle lock-breaking (if you want any automatic
1660 breaking of locks to be done).
1664 - A daemon with `use chroot = no` and excluded items listed in the daemon
1665 config file now properly checks an absolute-path arg specified for these
1666 options: `--compare-dest`, `--link-dest`, `--copy-dest`, `--partial-dir`,
1667 `--backup-dir`, `--temp-dir`, and `--files-from`.
1669 - A daemon can now be told to disable all user- and group-name translation on
1670 a per-module basis. This avoids a potential problem with a writable daemon
1671 module that has `use chroot` enabled -- if precautions weren't taken, a user
1672 could try to add a missing library and get rsync to use it. This makes rsync
1673 safer by default, and more configurable when id- translation is not desired.
1674 See the daemon's `numeric ids` parameter for full details.
1676 - A chroot daemon can now indicate which part of its path should affect the
1677 chroot call, and which part should become an inside-chroot path for the
1678 module. This allows you to have outside-the-transfer paths (such as for
1679 libraries) even when you enable chroot protection. The idiom used in the
1680 rsyncd.conf file is: `path = /chroot/dirs/./dirs/inside`
1682 - If a file's data arrived successfully on the receiving side but the rename
1683 of the temporary file to the destination file failed AND the
1684 `--remove-source-files` (or the deprecated `--remove-sent-files`) option was
1685 specified, rsync no longer erroneously removes the associated source file.
1687 - Fixed the output of `-ii` when combined with one of the `--*-dest` options:
1688 it now itemizes all the items, not just the changed ones.
1690 - Made the output of all file types consistent when using a `--*-dest` option.
1691 Prior versions would output too many creation events for matching items.
1693 - The code that waits for a child pid now handles being interrupted by a
1694 signal. This fixes a problem with the pre-xfer exec function not being able
1695 to get the exit status from the script.
1697 - A negated filter rule (i.e. with a '!' modifier) no longer loses the
1698 negation when sending the filter rules to the remote rsync.
1700 - Fixed a problem with the `--out-format` (aka `--log-format`) option %f: it
1701 no longer outputs superfluous directory info for a non-daemon rsync.
1703 - Fixed a problem with `-vv` (double `--verbose`) and `--stats` when `pushing`
1704 files (which includes local copies). Version 2.6.9 would complete the copy,
1705 but exit with an error when the receiver output its memory stats.
1707 - If `--password-file` is used on a non-daemon transfer, rsync now complains
1708 and exits. This should help users figure out that they can't use this option
1709 to control a remote shell's password prompt.
1711 - Make sure that directory permissions of a newly-created destination
1712 directory are handled right when `--perms` is left off.
1714 - The itemized output of a newly-created destination directory is now output
1715 as a creation event, not a change event.
1717 - Improved `--hard-link` so that more corner cases are handled correctly when
1718 combined with options such as `--link-dest` and/or `--ignore-existing`.
1720 - The `--append` option no longer updates a file that has the same size.
1722 - Fixed a bug when combining `--backup` and `--backup-dir` with `--inplace`:
1723 any missing backup directories are now created.
1725 - Fixed a bug when using `--backup` and `--inplace` with `--whole-file` or
1726 `--read-batch`: backup files are actually created now.
1728 - The daemon pidfile is checked and created sooner in the startup sequence.
1730 - If a daemon module's `path` value is not an absolute pathname, the code now
1731 makes it absolute internally (making it work properly).
1733 - Ensure that a temporary file always has owner-write permission while we are
1734 writing to it. This avoids problems with some network filesystems when
1735 transferring read-only files.
1737 - Any errors output about password-file reading no longer cause an error at
1738 the end of the run about a partial transfer.
1740 - The `--read-batch` option for protocol 30 now ensures that several more
1741 options are set correctly for the current batch file: `--iconv`, `--acls`,
1742 `--xattrs`, `--inplace`, `--append`, and `--append-verify`.
1744 - Using `--only-write-batch` to a daemon receiver now works properly (older
1745 versions would update some files while writing the batch).
1747 - Avoid outputting a "file has vanished" message when the file is a broken
1748 symlink and `--copy-unsafe-links` or `--copy-dirlinks` is used (the code
1749 already handled this for `--copy-links`).
1751 - Fixed the combination of `--only-write-batch` and `--dry-run`.
1753 - Fixed rsync's ability to remove files that are not writable by the file's
1754 owner when rsync is running as the same user.
1756 - When transferring large files, the sender's hashtable of checksums is kept
1757 at a more reasonable state of fullness (no more than 80% full) so that the
1758 scanning of the hashtable will not bog down as the number of blocks
1763 - A new incremental-recursion algorithm is now used when rsync is talking to
1764 another 3.x version. This starts the transfer going more quickly (before all
1765 the files have been found), and requires much less memory. See the
1766 `--recursive` option in the manpage for some restrictions.
1768 - Lowered memory use in the non-incremental-recursion algorithm for typical
1769 option values (usually saving from 21-29 bytes per file).
1771 - The default `--delete` algorithm is now `--delete-during` when talking to a
1772 3.x rsync. This is a faster scan than using `--delete-before` (which is the
1773 default when talking to older rsync versions), and is compatible with the
1774 new incremental recursion mode.
1776 - Rsync now allows multiple remote-source args to be specified rather than
1777 having to rely on a special space-splitting side-effect of the remote-
1778 shell. Additional remote args must specify the same host or an empty one
1779 (e.g. empty: `:file1` or `::module/file2`). For example, this means that
1780 local use of brace expansion now works: `rsync -av host:dir/{f1,f2} .`
1782 - Added the `--protect-args` (`-s`) option, that tells rsync to send most of
1783 the command-line args at the start of the transfer rather than as args to
1784 the remote-shell command. This protects them from space-splitting, and only
1785 interprets basic wildcard special shell characters (`*?[`).
1787 - Added the `--delete-delay` option, which is a more efficient way to delete
1788 files at the end of the transfer without needing a separate delete pass.
1790 - Added the `--acls` (`-A`) option to preserve Access Control Lists. This is
1791 an improved version of the prior patch that was available, and it even
1792 supports OS X ACLs. If you need to have backward compatibility with old,
1793 ACL-patched versions of rsync, apply the acls.diff file from the patches
1796 - Added the `--xattrs` (`-X`) option to preserve extended attributes. This is
1797 an improved version of the prior patch that was available, and it even
1798 supports OS X xattrs (which includes their resource fork data). If you need
1799 to have backward compatibility with old, xattr-patched versions of rsync,
1800 apply the xattrs.diff file from the patches dir.
1802 - Added the `--fake-super` option that allows a non-super user to preserve all
1803 attributes of a file by using a special extended-attribute idiom. It even
1804 supports the storing of foreign ACL data on your backup server. There is
1805 also an analogous `fake super` parameter for an rsync daemon.
1807 - Added the `--iconv` option, which allows rsync to convert filenames from one
1808 character-set to another during the transfer. The default is to make this
1809 feature available as long as your system has `iconv_open()`. If compilation
1810 fails, specify `--disable-iconv` to configure, and then rebuild. If you want
1811 rsync to perform character-set conversions by default, you can specify
1812 `--enable-iconv=CONVERT_STRING` with the default value for the `--iconv`
1813 option that you wish to use. For example, `--enable-iconv=.` is a good
1814 choice. See the rsync manpage for an explanation of the `--iconv` option's
1817 - A new daemon config parameter, `charset`, lets you control the character-
1818 set that is used during an `--iconv` transfer to/from a daemon module. You
1819 can also set your daemon to refuse `no-iconv` if you want to force the
1820 client to use an `--iconv` transfer (requiring an rsync 3.x client).
1822 - Added the `--skip-compress=LIST` option to override the default list of file
1823 suffixes that will not be compressed when using `--compress` (`-z`).
1825 - The daemon's default for `dont compress` was extended to include: `*.7z`
1826 `*.mp[34]` `*.mov` `*.avi` `*.ogg` `*.jpg` `*.jpeg` and the name-matching routine was also
1827 optimized to run more quickly.
1829 - The `--max-delete` option now outputs a warning if it skipped any file
1830 deletions, including a count of how many deletions were skipped. (Older
1831 versions just silently stopped deleting things.)
1833 - You may specify `--max-delete=0` to a 3.0.0 client to request that it warn
1834 about extraneous files without deleting anything. If you're not sure what
1835 version the client is, you can use the less-obvious `--max-delete=-1`, as
1836 both old and new versions will treat that as the same request (though older
1837 versions don't warn).
1839 - The `--hard-link` option now uses less memory on both the sending and
1840 receiving side for all protocol versions. For protocol 30, the use of a
1841 hashtable on the sending side allows us to more efficiently convey to the
1842 receiver what files are linked together. This reduces the amount of data
1843 sent over the socket by a considerable margin (rather than adding more
1844 data), and limits the in-memory storage of the device+inode information to
1845 just the sending side for the new protocol 30, or to the receiving side when
1846 speaking an older protocol (note that older rsync versions kept the
1847 device+inode information on both sides).
1849 - The filter rules now support a perishable (`p`) modifier that marks rules
1850 that should not have an effect in a directory that is being deleted. e.g.
1851 `-f '-p .svn/'` would only affect `live` .svn directories.
1853 - Rsync checks all the alternate-destination args for validity (e.g.
1854 `--link-dest`). This lets the user know when they specified a directory that
1857 - If we get an ENOSYS error setting the time on a symlink, we don't complain
1858 about it anymore (for those systems that even support the setting of the
1859 modify-time on a symlink).
1861 - Protocol 30 now uses MD5 checksums instead of MD4.
1863 - Changed the `--append` option to not checksum the existing data in the
1864 destination file, which speeds up file appending.
1866 - Added the `--append-verify` option, which works like the older `--append`
1867 option (verifying the existing data in the destination file). For
1868 compatibility with older rsync versions, any use of `--append` that is
1869 talking protocol 29 or older will revert to the `--append-verify` method.
1871 - Added the `--contimeout=SECONDS` option that lets the user specify a
1872 connection timeout for rsync daemon access.
1874 - Documented and extended the support for the `RSYNC_CONNECT_PROG` variable
1875 that can be used to enhance the client side of a daemon connection.
1877 - Improved the dashes and double-quotes in the nroff manpage output.
1879 - Rsync now supports a lot more `--no-OPTION` override options.
1883 - The file-list sorting algorithm now uses a sort that keeps any same- named
1884 items in the same order as they were specified. This allows rsync to always
1885 ensure that the first of the duplicates is the one that will be included in
1886 the copy. The new sort is also faster than the glibc version of qsort() and
1889 - Rsync now supports the transfer of 64-bit timestamps (`time_t` values).
1891 - Made the file-deletion code use a little less stack when recursing through a
1892 directory hierarchy of extraneous files.
1894 - Fixed a build problem with older (2.x) versions of gcc.
1896 - Added some isType() functions that make dealing with signed characters
1897 easier without forcing variables via casts.
1899 - Changed strcat/strcpy/sprintf function calls to use safer versions.
1901 - Upgraded the included popt version to 1.10.2 and improved its use of
1902 string-handling functions.
1904 - Added missing prototypes for compatibility functions from the lib dir.
1906 - Configure determines if iconv() has a const arg, allowing us to avoid a
1909 - Made the sending of some numbers more efficient for protocol 30.
1911 - Make sure that a daemon process doesn't mind if the client was weird and
1912 omitted the `--server` option.
1914 - There are more internal logging categories available in protocol 30 than the
1915 age-old FINFO and FERROR, including `FERROR_XFER` and FWARN. These new
1916 categories allow some errors and warnings to go to stderr without causing an
1917 erroneous end-of-run warning about some files not being able to be
1920 - Improved the use of `const` on pointers.
1922 - Improved J.W.'s `pool_alloc` routines to add a way of incrementally freeing
1923 older sections of a pool's memory.
1925 - The getaddrinfo.c compatibility code in the `lib` dir was replaced with some
1926 new code (derived from samba, derived from PostgreSQL) that has a better
1927 license than the old code.
1929 ### DEVELOPER RELATED:
1931 - Rsync is now licensed under the GPLv3 or later.
1933 - Rsync is now being maintained in a `git` repository instead of CVS (though
1934 the old CVS repository still exists for historical access). Several
1935 maintenance scripts were updated to work with git.
1937 - Generated files are no longer committed into the source repository. The
1938 autoconf and autoheader commands are now automatically run during the normal
1939 use of `configure` and `make`. The latest dev versions of all generated
1940 files can also be copied from the samba.org web site (see the prepare-source
1941 script's fetch option).
1943 - The `patches` directory of diff files is now built from branches in the
1944 rsync git repository (branch patch/FOO creates file patches/FOO.diff). This
1945 directory is now distributed in a separate separate tar file named
1946 rsync-patches-VERSION.tar.gz instead of the main rsync-VERSION.tar.gz.
1948 - The proto.h file is now built using a simple perl script rather than a
1949 complex awk script, which proved to be more widely compatible.
1951 - When running the tests, we now put our per-test temp dirs into a sub-
1952 directory named testtmp (which is created, if missing). This allows someone
1953 to symlink the testtmp directory to another filesystem (which is useful if
1954 the build dir's filesystem does not support ACLs and xattrs, but another
1957 - Rsync now has a way of handling protocol-version changes during the
1958 development of a new protocol version. This causes any out-of-sync versions
1959 to speak an older protocol rather than fail in a cryptic manner. This
1960 addition makes it safer to deploy a pre-release version that may interact
1961 with the public. This new exchange of sub-version info does not interfere
1962 with the `{MIN,MAX}_PROTOCOL_VERSION` checking algorithm (which does not
1963 have enough range to allow the main protocol number to be incremented for
1964 every minor tweak in that happens during development).
1966 - The csprotocol.txt file was updated to mention the daemon protocol change in

1972 # NEWS for rsync 2.6.9 (6 Nov 2006)
1974 ## Changes in this version:
1978 - If rsync is interrupted via a handled signal (such as SIGINT), it will once
1979 again clean-up its temp file from the destination dir.
1981 - Fixed an overzealous sanitizing bug in the handling of the `--link-dest`,
1982 `--copy-dest`, and `--compare-dest` options to a daemon without chroot: if
1983 the copy's destination dir is deeper than the top of the module's path,
1984 these options now accept a safe number of parent-dir (../) references (since
1985 these options are relative to the destination dir). The old code incorrectly
1986 chopped off all `../` prefixes for these options, no matter how deep the
1987 destination directory was in the module's hierarchy.
1989 - Fixed a bug where a deferred info/error/log message could get sent directly
1990 to the sender instead of being handled by rwrite() in the generator. This
1991 fixes an `unexpected tag 3` fatal error, and should also fix a potential
1992 problem where a deferred info/error message from the receiver might bypass
1993 the log file and get sent only to the client process. (These problems could
1994 only affect an rsync daemon that was receiving files.)
1996 - Fixed a bug when `--inplace` was combined with a `--*-dest` option and we
1997 update a file's data using an alternate basis file. The code now notices
1998 that it needs to copy the matching data from the basis file instead of
1999 (wrongly) assuming that it was already present in the file.
2001 - Fixed a bug where using `--dry-run` with a `--*-dest` option with a path
2002 relative to a directory that does not yet exist: the affected option gets
2003 its proper path value so that the output of the dry-run is right.
2005 - Fixed a bug in the %f logfile escape when receiving files: the destination
2006 path is now included in the output (e.g. you can now tell when a user
2007 specifies a subdir inside a module).
2009 - If the receiving side fails to create a directory, it will now skip trying
2010 to update everything that is inside that directory.
2012 - If `--link-dest` is specified with `--checksum` but without `--times`, rsync
2013 will now allow a hard-link to be created to a matching link-dest file even
2014 when the file's modify-time doesn't match the server's file.
2016 - The daemon now calls more timezone-using functions prior to doing a chroot.
2017 This should help some C libraries to generate proper timestamps from inside
2018 a chrooted daemon (and to not try to access /etc/timezone over and over
2021 - Fixed a bug in the handling of an absolute `--partial-dir=ABS_PATH` option:
2022 it now deletes an alternate basis file from the partial-dir that was used to
2023 successfully update a destination file.
2025 - Fixed a bug in the handling of `--delete-excluded` when using a per-dir
2026 merge file: the merge file is now honored on the receiving side, and only
2027 its unqualified include/exclude commands are ignored (just as is done for
2028 global include/excludes).
2030 - Fixed a recent bug where `--delete` was not working when transferring from
2031 the root (/) of the filesystem with `--relative` enabled.
2033 - Fixed a recent bug where an `--exclude='*'` could affect the root (/) of the
2034 filesystem with `--relative` enabled.
2036 - When `--inplace` creates a file, it is now created with owner read/write
2037 permissions (0600) instead of no permissions at all. This avoids a problem
2038 continuing a transfer that was interrupted (since `--inplace` will not
2039 update a file that has no write permissions).
2041 - If either `--remove-source-files` or `--remove-sent-files` is enabled and we
2042 are unable to remove the source file, rsync now outputs an error.
2044 - Fixed a bug in the daemon's `incoming chmod` rule: newly-created directories
2045 no longer get the 'F' (file) rules applied to them.
2047 - Fixed an infinite loop bug when a filter rule was rejected due to being
2050 - When the server receives a `--partial-dir` option from the client, it no
2051 longer runs the client-side code that adds an assumed filter rule (since the
2052 client will be sending us the rules in the usual manner, and they may have
2053 chosen to override the auto-added rule).
2057 - Added the `--log-file=FILE` and `--log-file-format=FORMAT` options. These
2058 can be used to tell any rsync to output what it is doing to a log file.
2059 They work with a client rsync, a non-daemon server rsync (see the man page
2060 for instructions), and also allows the overriding of rsyncd.conf settings
2061 when starting a daemon.
2063 - The `--log-format` option was renamed to be `--out-format` to avoid
2064 confusing it with affecting the log-file output. (The old option remains as
2065 an alias for the new to preserve backward compatibility.)
2067 - Made `log file` and `syslog facility` settable on a per-module basis in the
2068 daemon's config file.
2070 - Added the `--remove-source-files` option as a replacement for the (now
2071 deprecated) `--remove-sent-files` option. This new option removes all
2072 non-dirs from the source directories, even if the file was already
2073 up-to-date. This fixes a problem where interrupting an rsync that was using
2074 `--remove-sent-files` and restarting it could leave behind a file that the
2075 earlier rsync synchronized, but didn't get to remove. (The deprecated
2076 `--remove-sent-files` is still understood for now, and still behaves in the
2077 same way as before.)
2079 - Added the option `--no-motd` to suppress the message-of-the-day output from
2080 a daemon when doing a copy. (See the manpage for a caveat.)
2082 - Added a new environment variable to the pre-/post-xfer exec commands (in the
2083 daemon's config file): `RSYNC_PID`. This value will be the same in both the
2084 pre- and post-xfer commands, so it can be used as a unique ID if the
2085 pre-xfer command wants to cache some arg/request info for the post-xfer
2090 - Did a code audit using IBM's code-checker program and made several changes,
2091 including: replacing most of the strcpy() and sprintf() calls with
2092 strlcpy(), snprintf(), and memcpy(), adding a 0-value to an enum that had
2093 been intermingling a literal 0 with the defined enum values, silencing some
2094 uninitialized memory checks, marking some functions with a `noreturn`
2095 attribute, and changing an `if` that could never succeed on some platforms
2096 into a pre-processor directive that conditionally compiles the code.
2098 - Fixed a potential bug in `f_name_cmp()` when both the args are a top-level
2099 `.` dir (which doesn't happen in normal operations).
2101 - Changed `exit_cleanup()` so that it can never return instead of exit. The
2102 old code might return if it found the `exit_cleanup()` function was being
2103 called recursively. The new code is segmented so that any recursive calls
2104 move on to the next step of the exit-processing.
2106 - The macro WIFEXITED(stat) will now be defined if the OS didn't already
2109 ### DEVELOPER RELATED:
2111 - The acls.diff and xattrs.diff patches have received a bunch of work to make
2112 them much closer to being acceptable in the main distribution. The xattrs
2113 patch also has some preliminary Mac OS X and FreeBSD compatibility code that
2114 various system types to exchange extended file-attributes.
2116 - A new diff in the patches dir, fake-root.diff, allows rsync to maintain a
2117 backup hierarchy with full owner, group, and device info without actually
2118 running as root. It does this using a special extended attribute, so it
2119 depends on xattrs.diff (which depends on acls.diff).
2121 - The rsync.yo and rsyncd.conf.yo files have been updated to work better with
2122 the latest yodl 2.x releases.
2124 - Updated config.guess and config.sub to their 2006-07-02 versions.
2126 - Updated various files to include the latest FSF address and to have
2127 consistent opening comments.

2132 # NEWS for rsync 2.6.8 (22 Apr 2006)
2134 ## Changes in this version:
2138 - Fixed a bug in the exclude code where an anchored exclude without any
2139 wildcards fails to match an absolute source arg, but only when `--relative`
2142 - Improved the I/O code for the generator to fix a potential hang when the
2143 receiver gets an EOF on the socket but the generator's select() call never
2144 indicates that the socket is writable for it to be notified about the EOF.
2145 (This can happen when using stunnel).
2147 - Fixed a problem with the file-reading code where a failed read (such as that
2148 caused by a bad sector) would not advance the file's read-position beyond
2149 the failed read's data.
2151 - Fixed a logging bug where the `log file` directive was not being honored in
2152 a single-use daemon (one spawned by a remote-shell connection or by init).
2154 - If rsync cannot honor the `--delete` option, we output an error and exit
2155 instead of silently ignoring the option.
2157 - Fixed a bug in the `--link-dest` code that prevented special files (such as
2158 fifos) from being linked.
2160 - The ability to hard-link symlinks and special files is now determined at
2161 configure time instead of at runtime. This fixes a bug with `--link-dest`
2162 creating a hard-link to a symlink's referent on a BSD system.
2166 - In daemon mode, if rsync fails to bind to the requested port, the error(s)
2167 returned by socket() and/or bind() are now logged.
2169 - When we output a fatal error, we now output the version of rsync in the
2172 - Improved the documentation for the `--owner` and `--group` options.
2174 - The rsyncstats script in `support` has an improved line-parsing regex that
2175 is easier to read and also makes it to parse syslog-generated lines.
2177 - A new script in `support`: file-attr-restore, can be used to restore the
2178 attributes of a file-set (the permissions, ownership, and group info) taken
2179 from the cached output of a `find ARG... -ls` command.
2181 ### DEVELOPER RELATED:
2183 - Removed the unused function `write_int_named()`, the unused variable
2184 `io_read_phase`, and the rarely used variable `io_write_phase`. This also
2185 elides the confusing 'phase "unknown"' part of one error message.
2187 - Removed two unused configure checks and two related (also unused)
2188 compatibility functions.
2190 - The xattrs.diff patch received a security fix that prevents a potential
2191 buffer overflow in the `receive_xattr()` code.
2193 - The acls.diff patch has been improved quite a bit, with more to come.
2195 - A new patch was added: log-file.diff. This contains an early version of a
2196 future option, `--log-file=FILE`, that will allow any rsync to log its
2197 actions to a file (something that only a daemon supports at present).

2202 # NEWS for rsync 2.6.7 (11 Mar 2006)
2204 ## Changes in this version:
2208 - The letter 'D' in the itemized output was being used for both devices
2209 (character or block) as well as other special files (such as fifos and named
2210 sockets). This has changed to separate non-device special files under the
2211 'S' designation (e.g. `cS+++++++ path/fifo`). See also the `--specials`
2214 - The way rsync escapes unreadable characters has changed. First, rsync now
2215 has support for recognizing valid multibyte character sequences in your
2216 current locale, allowing it to escape fewer characters than before for a
2217 locale such as UTF-8. Second, it now uses an escape idiom of `\#123`, which
2218 is the literal string `\#` followed by exactly 3 octal digits. Rsync no
2219 longer doubles a backslash character in a filename (e.g. it used to output
2220 `foo\\bar` when copying `foo\bar`) -- now it only escapes a backslash that
2221 is followed by a hash-sign and 3 digits (0-9) (e.g. it will output
2222 `foo\#134#789` when copying `foo\#789`). See also the `--8-bit-output`
2223 (`-8`) option, mentioned below.
2225 Script writers: the local rsync is the one that outputs escaped names, so if
2226 you need to support unescaping of filenames for older rsyncs, I'd suggest
2227 that you parse the output of `rsync --version` and only use the old
2228 unescaping rules for 2.6.5 and 2.6.6.
2232 - Fixed a really old bug that caused `--checksum` (`-c`) to checksum all the
2233 files encountered during the delete scan (ouch).
2235 - Fixed a potential hang in a remote generator: when the receiver gets a
2236 read-error on the socket, it now signals the generator about this so that
2237 the generator does not try to send any of the terminating error messages to
2238 the client (avoiding a potential hang in some setups).
2240 - Made hard-links work with symlinks and devices again.
2242 - If the sender gets an early EOF reading a source file, we propagate this
2243 error to the receiver so that it can discard the file and try requesting it
2244 again (which is the existing behavior for other kinds of read errors).
2246 - If a device-file/special-file changes permissions, rsync now updates the
2247 permissions without recreating the file.
2249 - If the user specifies a remote-host for both the source and destination, we
2250 now output a syntax error rather than trying to open the destination
2251 hostspec as a filename.
2253 - When `--inplace` creates a new destination file, rsync now creates it with
2254 permissions 0600 instead of 0000 -- this makes restarting possible when the
2255 transfer gets interrupted in the middle of sending a new file.
2257 - Reject the combination of `--inplace` and `--sparse` since the sparse-output
2258 algorithm doesn't work when overwriting existing data.
2260 - Fixed the directory name in the error that is output when `pop_dir()` fails.
2262 - Really fixed the parsing of a `!` entry in .cvsignore files this time.
2264 - If the generator gets a stat() error on a file, output it (this used to
2265 require at least `-vv` for the error to be seen).
2267 - If waitpid() fails or the child rsync didn't exit cleanly, we now handle the
2268 exit status properly and generate a better error.
2270 - Fixed some glitches in the double-verbose output when using `--copy-dest`,
2271 `--link-dest`, or `--compare-dest`. Also improved how the verbose output
2272 handles hard-links (within the transfer) that had an up-to-date alternate
2273 `dest` file, and copied files (via `--copy-dest`).
2275 - Fixed the matching of the dont-compress items (e.g. `*.gz`) against files
2276 that have a path component containing a slash.
2278 - If the code reading a filter/exclude file gets an EINTR error, rsync now
2279 clears the error flag on the file handle so it can keep on reading.
2281 - If `--relative` is active, the sending side cleans up trailing `/` or `/.`
2282 suffixes to avoid triggering a bug in older rsync versions. Also, we now
2283 reject a `..` dir if it would be sent as a relative dir.
2285 - If a non-directory is in the way of a directory and rsync is run with
2286 `--dry-run` and `--delete`, rsync no longer complains about not being able
2287 to opendir() the not-yet present directory.
2289 - When `--list-only` is used and a non-existent local destination dir was also
2290 specified as a destination, rsync no longer generates a warning about being
2291 unable to create the missing directory.
2293 - Fixed some problems with `--relative --no-implied-dirs` when the destination
2294 directory did not yet exist: we can now create a symlink or device when it
2295 is the first thing in the missing dir, and `--fuzzy` no longer complains
2296 about being unable to open the missing dir.
2298 - Fixed a bug where the `--copy-links` option would not affect implied
2299 directories without `--copy-unsafe-links` (see `--relative`).
2301 - Got rid of the need for `--force` to be used in some circumstances with
2302 `--delete-after` (making it consistent with
2303 `--delete-before`/`--delete-during`).
2305 - Rsync now ignores the SIGXFSZ signal, just in case your OS sends this when a
2306 file is too large (rsync handles the write error).
2308 - Fixed a bug in the Proxy-Authorization header's base64-encoded value: it was
2309 not properly padded with trailing '=' chars. This only affects a user that
2310 need to use a password-authenticated proxy for an outgoing daemon-rsync
2313 - If we're transferring an empty directory to a new name, rsync no longer
2314 forces `S_IWUSR` if it wasn't already set, nor does it accidentally leave it
2317 - Fixed a bug in the debug output (`-vvvvv`) that could mention the wrong
2318 checksum for the current file offset.
2320 - Rsync no longer allows a single directory to be copied over a non- directory
2325 - Added the `--append` option that makes rsync append data onto files that are
2326 longer on the source than the destination (this includes new files).
2328 - Added the `--min-size=SIZE` option to exclude small files from the transfer.
2330 - Added the `--compress-level` option to allow you to set how aggressive
2331 rsync's compression should be (this option implies `--compress`).
2333 - Enhanced the parsing of the SIZE value for `--min-size` and `--max-size` to
2334 allow easy entry of multiples of 1000 (instead of just multiples of 1024)
2335 and off-by-one values too (e.g. `--max-size=8mb-1`).
2337 - Added the `--8-bit-output` (`-8`) option, which tells rsync to avoid
2338 escaping high-bit characters that it thinks are unreadable in the current
2341 - The new option `--human-readable` (`-h`) changes the output of `--progress`,
2342 `--stats`, and the end-of-run summary to be easier to read. If repeated, the
2343 units become powers of 1024 instead of powers of 1000. (The old meaning of
2344 `-h`, as a shorthand for `--help`, still works as long as you just use it on
2345 its own, as in `rsync -h`.)
2347 - If lutimes() and/or lchmod() are around, use them to allow the preservation
2348 of attributes on symlinks.
2350 - The `--link-dest` option now affects symlinks and devices (when possible).
2352 - Added two config items to the rsyncd.conf parsing: `pre-xfer exec` and
2353 `post-xfer exec`. These allow a command to be specified on a per-module
2354 basis that will be run before and/or after a daemon-mode transfer. (See the
2355 man page for a list of the environment variables that are set with
2356 information about the transfer.)
2358 - When using the `--relative` option, you can now insert a dot dir in the
2359 source path to indicate where the replication of the source dirs should
2360 start. For example, if you specify a source path of
2361 rsync://host/module/foo/bar/./baz/dir with `-R`, rsync will now only
2362 replicate the `baz/dir` part of the source path (note: a trailing dot dir is
2363 unaffected unless it also has a trailing slash).
2365 - Added some new `--no-FOO` options that make it easier to override unwanted
2366 implied or default options. For example, `-a --no-o` (aka `--archive
2367 --no-owner`) can be used to turn off the preservation of file ownership that
2370 - Added the `--chmod=MODE` option that allows the destination permissions to
2371 be changed from the source permissions. E.g. `--chmod=g+w,o-rwx`
2373 - Added the `incoming chmod` and `outgoing chmod` daemon options that allow a
2374 module to specify what permissions changes should be applied to all files
2375 copied to and from the daemon.
2377 - Allow the `--temp-dir` option to be specified when starting a daemon, which
2378 sets the default temporary directory for incoming files.
2380 - If `--delete` is combined with `--dirs` without `--recursive`, rsync will
2381 now delete in any directory whose content is being synchronized.
2383 - If `--backup` is combined with `--delete` without `--backup-dir` (and
2384 without `--delete-excluded`), we add a `protect` filter-rule to ensure that
2385 files with the backup suffix are not deleted.
2387 - The file-count stats that are output by `--progress` were improved to better
2388 indicate what the numbers mean. For instance, the output: `(xfer#5,
2389 to-check=8383/9999)` indicates that this was the fifth file to be
2390 transferred, and we still need to check 8383 more files out of a total of
2393 - The include/exclude code now allows a `dir/***` directive (with 3 trailing
2394 stars) to match both the dir itself as well as all the content below the dir
2395 (`dir/**` would not match the dir).
2397 - Added the `--prune-empty-dirs` (`-m`) option that makes the receiving rsync
2398 discard empty chains of directories from the file-list. This makes it easier
2399 to selectively copy files from a source hierarchy and end up with just the
2400 directories needed to hold the resulting files.
2402 - If the `--itemize-changes` (`-i`) option is repeated, rsync now includes
2403 unchanged files in the itemized output (similar to `-vv`, but without all
2404 the other verbose messages that can get in the way). Of course, the client
2405 must be version 2.6.7 for this to work, but the remote rsync only needs to
2406 be 2.6.7 if you're pushing files.
2408 - Added the `--specials` option to tell rsync to copy non-device special files
2409 (which rsync now attempts even as a normal user). The `--devices` option now
2410 requests the copying of just devices (character and block). The `-D` option
2411 still requests both (e.g. `--devices` and `--specials`), `-a` still implies
2412 `-D`, and non-root users still get a silent downgrade that omits device
2415 - Added the `--super` option to make the receiver always attempt super-user
2416 activities. This is useful for systems that allow things such as devices to
2417 be created or ownership to be set without being UID 0, and is also useful
2418 for someone who wants to ensure that errors will be output if the receiving
2419 rsync isn't being run as root.
2421 - Added the `--sockopts` option for those few who want to customize the TCP
2422 options used to contact a daemon rsync.
2424 - Added a way for the `--temp-dir` option to be combined with a partial-dir
2425 setting that lets rsync avoid non-atomic updates (for those times when
2426 `--temp-dir` is not being used because space is tight).
2428 - A new support script, files-to-excludes, will transform a list of files into
2429 a set of include/exclude directives that will copy those files.
2431 - A new option, `--executability` (`-E`) can be used to preserve just the
2432 execute bit on files, for those times when using the `--perms` option is not
2435 - The daemon now logs each connection and also each module-list request that
2438 - New log-format options: %M (modtime), %U (uid), %G (gid), and %B (permission
2439 bits, e.g. `rwxr-xrwt`).
2441 - The `--dry-run` option no longer forces the enabling of `--verbose`.
2443 - The `--remove-sent-files` option now does a better job of incrementally
2444 removing the sent files on the sending side (older versions tended to clump
2445 up all the removals at the end).
2447 - A daemon now supersedes its minimal SIGCHLD handler with the standard
2448 PID-remembering version after forking. This ensures that the generator can
2449 get the child-exit status from the receiver.
2451 - Use of the `--bwlimit` option no longer interferes with the remote rsync
2452 sending error messages about invalid/refused options.
2454 - Rsync no longer returns a usage error when used with one local source arg
2455 and no destination: this now implies the `--list-only` option, just like the
2456 comparable situation with a remote source arg.
2458 - Added the `--copy-dirlinks` option, a more limited version of
2461 - Various documentation improvements, including: a better synopsis, some
2462 improved examples, a better discussion of the presence and absence of
2463 `--perms` (including how it interacts with the new `--executability` and
2464 `--chmod` options), an extended discussion of `--temp-dir`, an improved
2465 discussion of `--partial-dir`, a better description of rsync's pattern
2466 matching characters, an improved `--no-implied-dirs` section, and the
2467 documenting of what the `--stats` option outputs.
2469 - Various new and updated diffs in the patches dir, including: acls.diff,
2470 xattrs.diff, atimes.diff, detect-renamed.diff, and slp.diff.
2474 - We now use sigaction() and sigprocmask() if possible, and fall back on
2475 signal() if not. Using sigprocmask() ensures that rsync enables all the
2476 signals that it needs, just in case it was started in a masked state.
2478 - Some buffer sizes were expanded a bit, particularly on systems where
2479 MAXPATHLEN is overly small (e.g. cygwin).
2481 - If `io_printf()` tries to format more data than fits in the buffer, exit
2482 with an error instead of transmitting a truncated buffer.
2484 - If a `va_copy` macro is defined, lib/snprintf.c will use it when defining
2485 the `VA_COPY` macro.
2487 - Reduced the amount of stack memory needed for each level of directory
2488 recursion by nearly MAXPATHLEN bytes.
2490 - The wildmatch function was extended to allow an array of strings to be
2491 supplied as the string to match. This allows the exclude code to do less
2494 - Got rid of the `safe_fname()` function (and all the myriad calls) and
2495 replaced it with a new function in the log.c code that filters all the
2496 output going to the terminal.
2498 - Unified the `f_name()` and the `f_name_to()` functions.
2500 - Improved the hash-table code the sender uses to handle checksums to make it
2501 use slightly less memory and run just a little faster.
2503 ### DEVELOPER RELATED:
2505 - The diffs in the patches dir now require `patch -p1 <DIFF` instead of the
2506 previous `-p0`. Also, the version included in the release tar now affect
2507 generated files (e.g. configure, rsync.1, proto.h, etc.), so it is no longer
2508 necessary to run autoconf and/or yodl unless you're applying a patch that
2509 was checked out from CVS.
2511 - Several diffs in the patches dir now use the proper `--enable-FOO` configure
2512 option instead of `--with-FOO` to turn on the inclusion of the newly patched
2515 - There is a new script, `prepare-source` than can be used to update the
2516 various generated files (proto.h, configure, etc.) even before configure has
2517 created the Makefile (this is mainly useful when patching the source with a
2518 patch that doesn't affect generated files).
2520 - The testsuite now sets HOME so that it won't be affected by a file such as

2526 # NEWS for rsync 2.6.6 (28 Jul 2005)
2528 ## Changes in this version:
2532 - The zlib code was upgraded to version 1.2.3 in order to make it more secure.
2533 While the widely-publicized security problem in zlib 1.2.2 did not affect
2534 rsync, another security problem surfaced that affects rsync's zlib 1.1.4.
2538 - The setting of `flist->high` in `clean_flist()` was wrong for an empty list.
2539 This could cause `flist_find()` to crash in certain rare circumstances (e.g.
2540 if just the right directory setup was around when `--fuzzy` was combined
2541 with `--link-dest`).
2543 - The outputting of hard-linked files when verbosity was > 1 was not right:
2544 (1) Without `-i` it would output the name of each hard-linked file as though
2545 it had been changed; it now outputs a `is hard linked` message for the file.
2546 (2) With `-i` it would output all dots for the unchanged attributes of a
2547 hard-link; it now changes those dots to spaces, as is done for other totally
2550 - When backing up a changed symlink or device, get rid of any old backup item
2551 so that we don't get an `already exists` error.
2553 - A couple places that were comparing a local and a remote modification- time
2554 were not honoring the `--modify-window` option.
2556 - Fixed a bug where the 'p' (permissions) itemized-changes flag might get set
2557 too often (if some non-significant mode bits differed).
2559 - Fixed a really old, minor bug that could cause rsync to warn about being
2560 unable to mkdir() a path that ends in `/.` because it just created the
2561 directory (required `--relative`, `--no-implied-dirs`, a source path that
2562 ended in either a trailing slash or a trailing `/.`, and a non-existing
2563 destination dir to tickle the bug in a recent version).
2567 - Made the `max verbosity` setting in the rsyncd.conf file settable on a
2568 per-module basis (which now matches the documentation).
2570 - The support/rrsync script has been upgraded to verify the args of options
2571 that take args (instead of rejecting any such options). The script was also
2572 changed to try to be more secure and to fix a problem in the parsing of a
2573 pull operation that has multiple sources.
2575 - Improved the documentation that explains the difference between a normal
2576 daemon transfer and a daemon-over remote-shell transfer.
2578 - Some of the diffs supplied in the patches dir were fixed and/or improved.
2582 - Made configure define `NOBODY_USER` (currently hard-wired to `nobody`) and
2583 `NOBODY_GROUP` (set to either `nobody` or `nogroup` depending on what we
2584 find in the /etc/group file).
2586 - Added a test to the test suite, itemized.test, that tests the output of `-i`
2587 (log-format w/%i) and some double-verbose messages.
2589 ------------------------------------------------------------------------------

2592 # NEWS for rsync 2.6.5 (1 Jun 2005)
2594 ## Changes in this version:
2598 - Non-printable chars in filenames are now output using backslash- escaped
2599 characters rather than '?'s. Any non-printable character is output using 3
2600 digits of octal (e.g. `\n` -> `\012`), and a backslash is now output as
2601 `\\`. Rsync also uses your locale setting, which can make it treat fewer
2602 high-bit characters as non-printable.
2604 - If rsync received an empty file-list when pulling files, it would output a
2605 `nothing to do` message and exit with a 0 (success) exit status, even if the
2606 remote rsync returned an error (it did not do this under the same conditions
2607 when pushing files). This was changed to make the pulling behavior the same
2608 as the pushing behavior: we now do the normal end-of-run outputting
2609 (depending on options) and exit with the appropriate exit status.
2613 - A crash bug was fixed when a daemon had its `path` set to `/`, did not have
2614 chroot enabled, and used some anchored excludes in the rsyncd.conf file.
2616 - Fixed a bug in the transfer of a single file when `-H` is specified (rsync
2617 would either infinite loop or perhaps crash).
2619 - Fixed a case where the generator might try (and fail) to tweak the
2620 write-permissions of a read-only directory in list-only mode (this only
2621 caused an annoying warning message).
2623 - If `--compare-dest` or `--link-dest` uses a locally-copied file as the basis
2624 for an updated version, log this better when `--verbose` or `-i` is in
2627 - Fixed the accidental disabling of `--backup` during the `--delete-after`
2630 - Restored the ability to use the `--address` option in client mode (in
2631 addition to its use in daemon mode).
2633 - Make sure that some temporary progress information from the delete
2634 processing does not get left on the screen when it is followed by a newline.
2636 - When `--existing` skips a directory with extra verbosity, refer to it as a
2637 `directory`, not a `file`.
2639 - When transferring a single file to a different-named file, any generator
2640 messages that are source-file related no longer refer to the file by the
2641 destination filename.
2643 - Fixed a bug where hard-linking a group of files might fail if the generator
2644 hasn't created a needed destination directory yet.
2646 - Fixed a bug where a hard-linked group of files that is newly-linked to a
2647 file in a `--link-dest` dir doesn't link the files from the rest of the
2650 - When deleting files with the `--one-file-system` (`-x`) option set, rsync no
2651 longer tries to remove files from inside a mount-point on the receiving
2652 side. Also, we don't complain about being unable to remove the mount-point
2655 - Fixed a compatibility problem when using `--cvs-ignore` (`-C`) and sending
2656 files to an older rsync without using `--delete`.
2658 - Make sure that a `- !` or `+ !` include/exclude pattern does not trigger the
2659 list-clearing action that is reserved for `!`.
2661 - Avoid a timeout in the generator when the sender/receiver aren't handling
2662 the generator's checksum output quickly enough.
2664 - Fixed the omission of some directories in the delete processing when
2665 `--relative` (`-R`) was combined with a source path that had a trailing
2668 - Fixed a case where rsync would erroneously delete some files and then
2669 re-transfer them when the options `--relative` (`-R`) and `--recursive`
2670 (`-r`) were both enabled (along with `--delete`) and a source path had a
2673 - Make sure that `--max-size` doesn't affect a device or a symlink.
2675 - Make sure that a system with a really small MAXPATHLEN does not cause the
2676 buffers in `readfd_unbuffered()` to be too small to receive normal messages.
2677 (This mainly affected Cygwin.)
2679 - If a source pathname ends with a filename of `..`, treat it as if `../` had
2680 been specified (so that we don't copy files to the parent dir of the
2683 - If `--delete` is combined with a file-listing rsync command (i.e. no
2684 transfer is happening), avoid outputting a warning that we couldn't delete
2687 - If `--stats` is specified with `--delete-after`, ensure that all the
2688 `deleting` messages are output before the statistics.
2690 - Improved one `if` in the deletion code that was only checking errno for
2691 ENOTEMPTY when it should have also been checking for EEXIST (for
2692 compatibility with OS variations).
2696 - Added the `--only-write-batch=FILE` option that may be used (instead of
2697 `--write-batch=FILE`) to create a batch file without doing any actual
2698 updating of the destination. This allows you to divert all the file-updating
2699 data away from a slow data link (as long as you are pushing the data to the
2700 remote server when creating the batch).
2702 - When the generator is taking a long time to fill up its output buffer (e.g.
2703 if the transferred files are few, small, or missing), it now periodically
2704 flushes the output buffer so that the sender/receiver can get started on the
2705 files sooner rather than later.
2707 - Improved the keep-alive code to handle a long silence between the sender and
2708 the receiver that can occur when the sender is receiving the checksum data
2711 - Improved the auth-errors that are logged by the daemon to include some
2712 information on why the authorization failed: wrong user, password mismatch,
2713 etc. (The client-visible message is unchanged!)
2715 - Improved the client's handling of an `@ERROR` from a daemon so that it does
2716 not complain about an unexpectedly closed socket (since we really did expect
2717 the socket to close).
2719 - If the daemon can't open the log-file specified in rsyncd.conf, fall back to
2720 using syslog and log an appropriate warning. This is better than what was
2721 typically a totally silent (and fatal) failure (since a daemon is not
2722 usually run with the `--no-detach` option that was necessary to see the
2725 - The man pages now consistently refer to an rsync daemon as a `daemon`
2726 instead of a `server` (to distinguish it from the server process in a
2727 non-daemon transfer).
2729 - Made a small change to the rrsync script (restricted rsync -- in the support
2730 dir) to make a read-only server reject all `--remove-*` options when sending
2731 files (to future-proof it against the possibility of other similar options
2732 being added at some point).
2736 - Rsync now calls `setlocale(LC_CTYPE, "")`. This enables isprint() to better
2737 discern which filename characters need to be escaped in messages (which
2738 should result in fewer escaped characters in some locales).
2740 - Improved the naming of the log-file open/reopen/close functions.
2742 - Removed some protocol-compatibility code that was only needed to help
2743 someone running a pre-release of 2.6.4.
2747 - Added configure option `--disable-locale` to disable any use of setlocale()
2750 - Fixed a bug in the `SUPPORT{,_HARD}_LINKS` #defines which prevented rsync
2751 from being built without symlink or hard-link support.
2753 - Only #define `HAVE_REMSH` if it is going to be set to 1.
2755 - Configure now disables the use of mkstemp() under HP-UX (since they refuse
2756 to fix its broken handling of large files).
2758 - Configure now explicitly checks for the lseek64() function so that the code
2759 can use `HAVE_LSEEK64` instead of inferring lseek64()'s presence based on
2760 the presence of the `off64_t` type.
2762 - Configure no longer mentions the change in the default remote-shell (from
2763 rsh to ssh) that occurred for the 2.6.0 release.
2765 - Some minor enhancements to the test scripts.
2767 - Added a few new `*.diff` files to the patches dir, including a patch that
2768 enables the optional copying of extended attributes.

2773 # NEWS for rsync 2.6.4 (30 March 2005)
2775 ## Changes in this version:
2777 ### PROTOCOL NUMBER:
2779 - The protocol number was changed to 29.
2783 - When rsync deletes a directory and outputs a verbose message about it, it
2784 now appends a trailing slash to the name instead of (only sometimes)
2785 outputting a preceding "directory " string.
2787 - The `--stats` output will contain file-list time-statistics if both sides
2788 are 2.6.4, or if the local side is 2.6.4 and the files are being pushed
2789 (since the stats come from the sending side). (Requires protocol 29 for a
2792 - The `%o` (operation) log-format escape now has a third value (besides `send`
2793 and `recv`): `del.` (with trailing dot to make it 4 chars). This changes
2794 the way deletions are logged in the daemon's log file.
2796 - When the `--log-format` option is combined with `--verbose`, rsync now
2797 avoids outputting the name of the file twice in most circumstances. As long
2798 as the `--log-format` item does not refer to any post-transfer items (such
2799 as %b or %c), the `--log-format` message is output prior to the transfer, so
2800 `--verbose` is now the equivalent of a `--log-format` of '%n%L' (which
2801 outputs the name and any link info). If the log output must occur after the
2802 transfer to be complete, the only time the name is also output prior to the
2803 transfer is when `--progress` was specified (so that the name will precede
2804 the progress stats, and the full `--log-format` output will come after).
2806 - Non-printable characters in filenames are replaced with a '?' to avoid
2807 corrupting the screen or generating empty lines in the output.
2811 - Restore the list-clearing behavior of `!` in a .cvsignore file (2.6.3 was
2812 only treating it as a special token in an rsync include/exclude file).
2814 - The combination of `--verbose` and `--dry-run` now mentions the full list of
2815 changes that would be output without `--dry-run`.
2817 - Avoid a mkdir warning when removing a directory in the destination that
2818 already exists in the `--backup-dir`.
2820 - An OS that has a binary mode for its files (such as cygwin) needed
2821 `setmode(fd, O_BINARY)` called on the temp-file we opened with mkstemp().
2822 (Fix derived from cygwin's 2.6.3 rsync package.)
2824 - Fixed a potential hang when verbosity is high, the client side is the
2825 sender, and the file-list is large.
2827 - Fixed a potential protocol-corrupting bug where the generator could merge a
2828 message from the receiver into the middle of a multiplexed packet of data if
2829 only part of that data had been written out to the socket when the message
2830 from the generator arrived.
2832 - We now check if the OS doesn't support using mknod() for creating FIFOs and
2833 sockets, and compile-in some compatibility code using mkfifo() and socket()
2836 - Fixed an off-by-one error in the handling of `--max-delete=N`. Also, if the
2837 `--max-delete` limit is exceeded during a run, we now output a warning about
2838 this at the end of the run and exit with a new error code (25).
2840 - One place in the code wasn't checking if fork() failed.
2842 - The `ignore nonreadable` daemon parameter used to erroneously affect
2843 readable symlinks that pointed to a non-existent file.
2845 - If the OS does not have lchown() and a chown() of a symlink will affect the
2846 referent of a symlink (as it should), we no longer try to set the user and
2849 - The generator now properly runs the hard-link loop and the dir-time
2850 rewriting loop after we're sure that the redo phase is complete.
2852 - When `--backup` was specified with `--partial-dir=DIR`, where DIR is a
2853 relative path, the backup code was erroneously trying to backup a file that
2854 was put into the partial-dir.
2856 - If a file gets resent in a single transfer and the `--backup` option is
2857 enabled along with `--inplace`, rsync no longer performs a duplicate backup
2858 (it used to overwrite the first backup with the failed file).
2860 - One call to `flush_write_file()` was not being checked for an error.
2862 - The `--no-relative` option was not being sent from the client to a server
2865 - If an rsync daemon specified `dont compress = ...` for a file and the client
2866 tried to specify `--compress`, the libz code was not handling a compression
2867 level of 0 properly. This could cause a transfer failure if the block-size
2868 for a file was large enough (e.g. rsync might have exited with an error for
2871 - Fixed a bug that would sometimes surface when using `--compress` and sending
2872 a file with a block-size larger than 64K (either manually specified, or
2873 computed due to the file being really large). Prior versions of rsync would
2874 sometimes fail to decompress the data properly, and thus the transferred
2875 file would fail its verification.
2877 - If a daemon can't open the specified log file (i.e. syslog is not being
2878 used), die without crashing. We also output an error about the failure on
2879 stderr (which will only be seen if `--no-detach` was specified) and exit
2880 with a new error code (6).
2882 - A local transfer no longer duplicates all its include/exclude options (since
2883 the forked process already has a copy of the exclude list, there's no need
2884 to send them a set of duplicates).
2886 - The output of the items that are being updated by the generator (dirs,
2887 symlinks, devices) is now intermingled in the proper order with the output
2888 from the items that the receiver is updating (regular files) when pulling.
2889 This misordering was particularly bad when `--progress` was specified.
2890 (Requires protocol 29.)
2892 - When `--timeout` is specified, lulls that occur in the transfer while the
2893 generator is doing work that does not generate socket traffic (looking for
2894 changed files, deleting files, doing directory-time touch-ups, etc.) will
2895 cause a new keep-alive packet to be sent that should keep the transfer going
2896 as long as the generator continues to make progress. (Requires protocol 29.)
2898 - The stat size of a device is not added to the total file size of the items
2899 in the transfer (the size might be undefined on some OSes).
2901 - Fixed a problem with refused-option messages sometimes not making it back to
2902 the client side when a remote `--files-from` was in effect and the daemon
2905 - The `--compare-dest` option was not updating a file that differed in (the
2906 preserved) attributes from the version in the compare-dest DIR.
2908 - When rsync is copying files into a write-protected directory, fixed the
2909 change-report output for the directory so that we don't report an identical
2910 directory as changed.
2914 - Rsync now supports popt's option aliases, which means that you can use
2915 /etc/popt and/or ~/.popt to create your own option aliases.
2917 - Added the `--delete-during` (`--del`) option which will delete files from
2918 the receiving side incrementally as each directory in the transfer is being
2919 processed. This makes it more efficient than the default,
2920 before-the-transfer behavior, which is now also available as
2921 `--delete-before` (and is still the default `--delete-WHEN` option that will
2922 be chosen if `--delete` or `--delete-excluded` is specified without a
2923 `--delete-WHEN` choice). All the `--del*` options infer `--delete`, so an
2924 rsync daemon that refuses `delete` will still refuse to allow any
2925 file-deleting options (including the new `--remove-sent-files` option).
2927 - All the `--delete-WHEN` options are now more memory efficient: Previously an
2928 duplicate set of file-list objects was created on the receiving side for the
2929 entire destination hierarchy. The new algorithm only creates one directory
2930 of objects at a time (for files inside the transfer).
2932 - Added the `--copy-dest` option, which works like `--link-dest` except that
2933 it locally copies identical files instead of hard-linking them.
2935 - Added support for specifying multiple `--compare-dest`, `--copy-dest`, or
2936 `--link-dest` options, but only of a single type. (Promoted from the patches
2937 dir and enhanced.) (Requires protocol 29.)
2939 - Added the `--max-size` option. (Promoted from the patches dir.)
2941 - The daemon-mode options are now separated from the normal rsync options so
2942 that they can't be mixed together. This makes it impossible to start a
2943 daemon that has improper default option values (which could cause problems
2944 when a client connects, such as hanging or crashing).
2946 - The `--bwlimit` option may now be used in combination with `--daemon` to
2947 specify both a default value for the daemon side and a value that cannot be
2948 exceeded by a user-specified `--bwlimit` option.
2950 - Added the `port` parameter to the rsyncd.conf file. (Promoted from the
2951 patches dir.) Also added `address`. The command-line options take precedence
2952 over a config-file option, as expected.
2954 - In `_exit_cleanup()`: when we are exiting with a partially-received file, we
2955 now flush any data in the write-cache before closing the partial file.
2957 - The `--inplace` support was enhanced to work with `--compare-dest`,
2958 `--link-dest`, and (the new) `--copy-dest` options. (Requires protocol 29.)
2960 - Added the `--dirs` (`-d`) option for an easier way to copy directories
2961 without recursion. Any directories that are encountered are created on the
2962 destination. Specifying a directory with a trailing slash copies its
2963 immediate contents to the destination.
2965 - The `--files-from` option now implies `--dirs` (`-d`).
2967 - Added the `--list-only` option, which is mainly a way for the client to put
2968 the server into listing mode without needing to resort to any internal
2969 option kluges (e.g. the age-old use of `-r --exclude='/*/*'` for a
2970 non-recursive listing). This option is used automatically (behind the
2971 scenes) when a modern rsync speaks to a modern daemon, but may also be
2972 specified manually if you want to force the use of the `--list-only` option
2973 over a remote-shell connection.
2975 - Added the `--omit-dir-times` (`-O`) option, which will avoid updating the
2976 modified time for directories when `--times` was specified. This option will
2977 avoid an extra pass through the file-list at the end of the transfer (to
2978 tweak all the directory times), which may provide an appreciable speedup for
2979 a really large transfer. (Promoted from the patches dir.)
2981 - Added the `--filter` (`-f`) option and its helper option, `-F`. Filter rules
2982 are an extension to the existing include/exclude handling that also supports
2983 nested filter files as well as per-directory filter files (like .cvsignore,
2984 but with full filter-rule parsing). This new option was chosen in order to
2985 ensure that all existing include/exclude processing remained 100% compatible
2986 with older versions. Protocol 29 is needed for full filter-rule support, but
2987 backward-compatible rules work with earlier protocol versions. (Promoted
2988 from the patches dir and enhanced.)
2990 - Added the `--delay-updates` option that puts all updated files into a
2991 temporary directory (by default `.~tmp~`, but settable via the
2992 `--partial-dir=DIR` option) until the end of the transfer. This makes the
2993 updates a little more atomic for a large transfer.
2995 - If rsync is put into the background, any output from `--progress` is
2998 - Documented the `max verbosity` setting for rsyncd.conf. (This setting was
2999 added a couple releases ago, but left undocumented.)
3001 - The sender and the generator now double-check the file-list index they are
3002 given, and refuse to try to do a file transfer on a non-file index (since
3003 that would indicate that something had gone very wrong).
3005 - Added the `--itemize-changes` (`-i`) option, which is a way to output a more
3006 detailed list of what files changed and in what way. The effect is the same
3007 as specifying a `--log-format` of `%i %n%L` (see both the rsync and
3008 rsyncd.conf manpages). Works with `--dry-run` too.
3010 - Added the `--fuzzy` (`-y`) option, which attempts to find a basis file for a
3011 file that is being created from scratch. The current algorithm only looks in
3012 the destination directory for the created file, but it does attempt to find
3013 a match based on size/mod-time (in case the file was renamed with no other
3014 changes) as well as based on a fuzzy name-matching algorithm. This option
3015 requires protocol 29 because it needs the new file-sorting order. (Promoted
3016 from patches dir and enhanced.) (Requires protocol 29.)
3018 - Added the `--remove-sent-files` option, which lets you move files between
3021 - The hostname in HOST:PATH or HOST::PATH may now be an IPv6 literal enclosed
3022 in '[' and ']' (e.g. `[::1]`). (We already allowed IPv6 literals in the
3023 rsync://HOST:PORT/PATH format.)
3025 - When rsync recurses to build the file list, it no longer keeps open one or
3026 more directory handles from the dir's parent dirs.
3028 - When building under windows, the default for `--daemon` is now to avoid
3029 detaching, requiring the new `--detach` option to force rsync to detach.
3031 - The `--dry-run` option can now be combined with either `--write-batch` or
3032 `--read-batch`, allowing you to run a do-nothing test command to see what
3033 would happen without `--dry-run`.
3035 - The daemon's `read only` config item now sets an internal `read_only`
3036 variable that makes extra sure that no write/delete calls on the read-only
3039 - The log-format % escapes can now have a numeric field width in between the %
3040 and the escape letter (e.g. `%-40n %08p`).
3042 - Improved the option descriptions in the `--help` text.
3046 - Added atomic-rsync to the support dir: a perl script that will transfer some
3047 files using rsync, and then move the updated files into place all at once at
3048 the end of the transfer. Only works when pulling, and uses `--link-dest` and
3049 a parallel hierarchy of files to effect its update.
3051 - Added mnt-excl to the support dir: a perl script that takes the /proc/mounts
3052 file and translates it into a set of excludes that will exclude all mount
3053 points (even mapped mounts to the same disk). The excludes are made relative
3054 to the specified source dir and properly anchored.
3056 - Added savetransfer.c to the support dir: a C program that can make a copy of
3057 all the data that flows over the wire. This lets you test for data
3058 corruption (by saving the data on both the sending side and the receiving
3059 side) and provides one way to debug a protocol error.
3061 - Added rrsync to the support dir: this is an updated version of Joe Smith's
3062 restricted rsync perl script. This helps to ensure that only certain rsync
3063 commands can be run by an ssh invocation.
3067 - Added better checking of the checksum-header values that come over the
3070 - Merged a variety of file-deleting functions into a single function so that
3071 it is easier to maintain.
3073 - Improved the type of some variables (particularly blocksize vars) for
3074 consistency and proper size.
3076 - Got rid of the uint64 type (which we didn't need).
3078 - Use a slightly more compatible set of core #include directives.
3080 - Defined int32 in a way that ensures that the build dies if we can't find a
3081 variable with at least 32 bits.
3083 ### PROTOCOL DIFFERENCES FOR VERSION 29:
3085 - A 16-bit flag-word is transmitted after every file-list index. This
3086 indicates what is changing between the sender and the receiver. The
3087 generator now transmits an index and a flag-word to indicate when dirs and
3088 symlinks have changed (instead of producing a message), which makes the
3089 outputting of the information more consistent and less prone to screen
3090 corruption (because the local receiver/sender is now outputting all the
3091 file-change info messages).
3093 - If a file is being hard-linked, the `ITEM_XNAME_FOLLOWS` bit is enabled in
3094 the flag-word and the name of the file that was linked immediately follows
3095 in vstring format (see below).
3097 - If a file is being transferred with an alternate-basis file, the
3098 `ITEM_BASIS_TYPE_FOLLOWS` bit is enabled in the flag-word and a single byte
3099 follows, indicating what type of basis file was chosen. If that indicates
3100 that a fuzzy-match was selected, the `ITEM_XNAME_FOLLOWS` bit is set in the
3101 flag-word and the name of the match in vstring format follows the basis
3102 byte. A vstring is a variable length string that has its size written prior
3103 to the string, and no terminating null. If the string is from 1-127 bytes,
3104 the length is a single byte. If it is from 128-32767 bytes, the length is
3105 written as ((len >> 8) | 0x80) followed by (len % 0x100).
3107 - The sending of exclude names is done using filter-rule syntax. This means
3108 that all names have a prefixed rule indicator, even excludes (which used to
3109 be sent as a bare pattern, when possible). The `-C` option will include the
3110 per-dir .cvsignore merge file in the list of filter rules so it is
3111 positioned correctly (unlike in some older transfer scenarios).
3113 - Rsync sorts the filename list in a different way: it sorts the subdir names
3114 after the non-subdir names for each dir's contents, and it always puts a
3115 dir's contents immediately after the dir's name in the list. (Previously an
3116 item named `foo.txt` would sort in between directory `foo/` and `foo/bar`.)
3118 - When talking to a protocol 29 rsync daemon, a list-only request is able to
3119 note this before the options are sent over the wire and the new
3120 `--list-only` option is included in the options.
3122 - When the `--stats` bytes are sent over the wire (or stored in a batch), they
3123 now include two elapsed-time values: one for how long it took to build the
3124 file-list, and one for how long it took to send it over the wire (each
3125 expressed in thousandths of a second).
3127 - When `--delete-excluded` is specified with some filter rules (AKA excludes),
3128 a client sender will now initiate a send of the rules to the receiver (older
3129 protocols used to omit the sending of excludes in this situation since there
3130 were no receiver-specific rules that survived `--delete-excluded` back
3131 then). Note that, as with all the filter-list sending, only items that are
3132 significant to the other side will actually be sent over the wire, so the
3133 filter-rule list that is sent in this scenario is often empty.
3135 - An index equal to the file-list count is sent as a keep-alive packet from
3136 the generator to the sender, which then forwards it on to the receiver. This
3137 normally invalid index is only a valid keep-alive packet if the 16-bit
3138 flag-word that follows it contains a single bit (`ITEM_IS_NEW`, which is
3139 normally an illegal flag to appear alone).
3141 - A protocol-29 batch file includes a bit for the setting of the `--dirs`
3142 option and for the setting of the `--compress` option. Also, the shell
3143 script created by `--write-batch` will use the `--filter` option instead of
3144 `--exclude-from` to capture any filter rules.
3148 - Handle an operating system that use mkdev() in place of makedev().
3150 - Improved configure to better handle cross-compiling.

3155 # NEWS for rsync 2.6.3 (30 Sep 2004)
3157 ## Changes in this version:
3161 - A bug in the `sanitize_path` routine (which affects a non-chrooted rsync
3162 daemon) could allow a user to craft a pathname that would get transformed
3163 into an absolute path for certain options (but not for file-transfer names).
3164 If you're running an rsync daemon with chroot disabled, **please upgrade**,
3165 ESPECIALLY if the user privs you run rsync under is anything above `nobody`.
3167 OUTPUT CHANGES (ATTN: those using a script to parse the verbose output):
3169 - Please note that the 2-line footer (output when verbose) now uses the term
3170 `sent` instead of `wrote` and `received` instead of `read`. If you are not
3171 parsing the numeric values out of this footer, a script would be better off
3172 using the empty line prior to the footer as the indicator that the verbose
3175 - The output from the `--stats` option was similarly affected to change
3176 `written` to `sent` and `read` to `received`.
3178 - Rsync ensures that a filename that contains a newline gets mentioned with
3179 each newline transformed into a question mark (which prevents a filename
3180 from causing an empty line to be output).
3182 - The `backed up ...` message that is output when at least 2 `--verbose`
3183 options are specified is now the same both with and without the
3184 `--backup-dir` option.
3188 - Fixed a crash bug that might appear when `--delete` was used and multiple
3189 source directories were specified.
3191 - Fixed a 32-bit truncation of the file length when generating the checksums.
3193 - The `--backup` code no longer attempts to create some directories over and
3194 over again (generating warnings along the way).
3196 - Fixed a bug in the reading of the secrets file (by the daemon) and the
3197 password file (by the client): the files no longer need to be terminated by
3198 a newline for their content to be read in.
3200 - If a file has a read error on the sending side or the reconstructed data
3201 doesn't match the expected checksum (perhaps due to the basis file changing
3202 during the transfer), the receiver will no longer retain the resulting file
3203 unless the `--partial` option was specified. (Note: for the read-error
3204 detection to work, neither side can be older than 2.6.3 -- older receivers
3205 will always retain the file, and older senders don't tell the receiver that
3206 the file had a read error.)
3208 - If a file gets resent in a single transfer and the `--backup` option is
3209 enabled, rsync no longer performs a duplicate backup (it used to overwrite
3210 the original file in the backup area).
3212 - Files specified in the daemon's `exclude` or `exclude from` config items are
3213 now excluded from being uploaded (assuming that the module allows uploading
3214 at all) in addition to the old download exclusion.
3216 - Got rid of a potential hang in the receiver when near the end of a phase.
3218 - When using `--backup` without a `--backup-dir`, rsync no longer preserves
3219 the modify time on directories. This avoids confusing NFS.
3221 - When `--copy-links` (`-L`) is specified, we now output a separate error for
3222 a symlink that has no referent instead of claiming that a file `vanished`.
3224 - The `--copy-links` (`-L`) option no longer has the side-effect of telling
3225 the receiving side to follow symlinks. See the `--keep-dirlinks` option
3226 (mentioned below) for a way to specify that behavior.
3228 - Error messages from the daemon server's option-parsing (such as refused
3229 options) are now successfully transferred back to the client (the server
3230 used to fail to send the message because the socket wasn't in the right
3231 state for the message to get through).
3233 - Most transfer errors that occur during a daemon transfer are now returned to
3234 the user in addition to being logged (some messages are intended to be
3235 daemon-only and are not affected by this).
3237 - Fixed a bug in the daemon authentication code when using one of the
3238 batch-processing options.
3240 - We try to work around some buggy IPv6 implementations that fail to implement
3241 `IPV6_V6ONLY`. This should fix the `address in use` error that some daemons
3242 get when running on an OS with a buggy IPv6 implementation. Also, if the new
3243 code gets this error, we might suggest that the user specify `--ipv4` or
3244 `--ipv6` (if we think it will help).
3246 - When the remote rsync dies, make a better effort to recover any error
3247 messages it may have sent before dying (the local rsync used to just die
3248 with a socket-write error).
3250 - When using `--delete` and a `--backup-dir` that contains files that are
3251 hard-linked to their destination equivalents, rsync now makes sure that
3252 removed files really get removed (avoids a really weird rename() behavior).
3254 - Avoid a bogus run-time complaint about a lack of 64-bit integers when the
3255 int64 type is defined as an `off_t` and it actually has 64-bits.
3257 - Added a configure check for open64() without mkstemp64() so that we can
3258 avoid using mkstemp() when such a combination is encountered. This bypasses
3259 a problem writing out large temp files on OSes such as AIX and HP-UX.
3261 - Fixed an age-old crash problem with `--read-batch` on a local copy (rsync
3262 was improperly assuming `--whole-file` for the local copy).
3264 - When `--dry-run` (`-n`) is used and the destination directory does not
3265 exist, rsync now produces a correct report of files that would be sent
3266 instead of dying with a chdir() error.
3268 - Fixed a bug that could cause a slow-to-connect rsync daemon to die with an
3269 error instead of waiting for the connection to finish.
3271 - Fixed an ssh interaction that could cause output to be lost when the user
3272 chose to combine the output of rsync's stdout and stderr (e.g. using the
3275 - Fixed an option-parsing bug when `--files-from` got passed to a daemon.
3279 - Added the `--partial-dir=DIR` option that lets you specify where to
3280 (temporarily) put a partially transferred file (instead of over- writing the
3281 destination file). E.g. `--partial-dir=.rsync-partial` Also added support
3282 for the `RSYNC_PARTIAL_DIR` environment variable that, when found,
3283 transforms a regular `--partial` option (such as the convenient `-P` option)
3284 into one that also specifies a directory.
3286 - Added `--keep-dirlinks` (`-K`), which allows you to symlink a directory onto
3287 another partition on the receiving side and have rsync treat it as matching
3288 a normal directory from the sender.
3290 - Added the `--inplace` option that tells rsync to write each destination file
3291 without using a temporary file. The matching of existing data in the
3292 destination file can be severely limited by this, but there are also cases
3293 where this is more efficient (such as appending data). Use only when needed
3294 (see the man page for more details).
3296 - Added the `write only` option for the daemon's config file.
3298 - Added long-option names for `-4` and `-6` (namely `--ipv4` and `--ipv6`) and
3299 documented all these options in the man page.
3301 - Improved the handling of the `--bwlimit` option so that it's less bursty,
3302 more accurate, and works properly over a larger range of values.
3304 - The rsync daemon-over-ssh code now looks for `SSH_CONNECTION` and
3305 `SSH2_CLIENT` in addition to `SSH_CLIENT` to figure out the IP address.
3307 - Added the `--checksum-seed=N` option for advanced users.
3309 - Batch writing/reading has a brand-new implementation that is simpler, fixes
3310 a few weird problems with the old code (such as no longer sprinkling the
3311 batch files into different dirs or even onto different systems), and is much
3312 less intrusive into the code (making it easier to maintain for the future).
3313 The new code generates just one data file instead of three, which makes it
3314 possible to read the batch on stdin via a remote shell. Also, the old
3315 requirement of forcing the same fixed checksum-seed for all batch processing
3318 - If an rsync daemon has a module set with `list = no` (which hides its
3319 presence in the list of available modules), a user that fails to
3320 authenticate gets the same `unknown module` error that they would get if the
3321 module were actually unknown (while still logging the real error to the
3322 daemon's log file). This prevents fishing for module names.
3324 - The daemon's `refuse options` config item now allows you to match option
3325 names using wildcards and/or the single-letter option names.
3327 - Each transferred file now gets its permissions and modified-time updated
3328 before the temp-file gets moved into place. Previously, the finished file
3329 would have a very brief window where its permissions disallowed all group
3332 - Added the ability to parse a literal IPv6 address in an `rsync:` URL (e.g.
3333 rsync://[2001:638:500:101::21]:873/module/dir).
3335 - The daemon's wildcard expanding code can now handle more than 1000 filenames
3336 (it's now limited by memory instead of having a hard-wired limit).
3340 - Some cleanup in the exclude code has saved some per-exclude memory and made
3341 the code easier to maintain.
3343 - Improved the argv-overflow checking for a remote command that has a lot of
3346 - Use rsyserr() in the various places that were still calling rprintf() with
3347 strerror() as an arg.
3349 - If an rsync daemon is listening on multiple sockets (to handle both IPv4 and
3350 IPv6 to a single port), we now close all the unneeded file handles after we
3351 accept a connection (we used to close just one of them).
3353 - Optimized the handling of larger block sizes (rsync used to slow to a crawl
3354 if the block size got too large).
3356 - Optimized away a loop in `hash_search()`.
3358 - Some improvements to the `sanitize_path()` and `clean_fname()` functions
3359 makes them more efficient and produce better results (while still being
3360 compatible with the file-name cleaning that gets done on both sides when
3361 sending the file-list).
3363 - Got rid of `alloc_sanitize_path()` after adding a destination-buffer arg to
3364 `sanitize_path()` made it possible to put all the former's functionality
3367 - The file-list that is output when at least 4 verbose options are specified
3368 reports the uid value on the sender even when rsync is not running as root
3369 (since we might be sending to a root receiver).
3373 - Added a `gen` target to rebuild most of the generated files, including
3374 configure, config.h.in, the man pages, and proto.h.
3376 - If `make proto` doesn't find some changes in the prototypes, the proto.h
3377 file is left untouched (its time-stamp used to always be updated).
3379 - The variable `$STRIP` (that is optionally set by the install-strip target's
3380 rule) was changed to `$INSTALL_STRIP` because some systems have `$STRIP`
3381 already set in the environment.
3383 - Fixed a build problem when `SUPPORT_HARD_LINKS` isn't defined.
3385 - When cross-compiling, the gettimeofday() function is now assumed to be a
3386 modern version that takes two-args (since we can't test it).
3388 ### DEVELOPER RELATED:
3390 - The scripts in the testsuite dir were cleaned up a bit and a few new tests

3399 # NEWS for rsync 2.6.2 (30 Apr 2004)
3401 ## Changes in this version:
3405 - Fixed a major bug in the sorting of the filenames when `--relative` is used
3406 for some sources (just sources such as `/` and `/*` were affected). This fix
3407 ensures that we ask for the right file-list item when requesting changes
3410 - Rsync now checks the return value of the close() function to better report
3411 disk-full problems on an NFS file system.
3413 - Restored the old daemon-server behavior of logging error messages rather
3414 than returning them to the user. (A better long-term fix will be sought in
3417 - An obscure uninitialized-variable bug was fixed in the uid/gid code. (This
3418 bug probably had no ill effects.)
3422 - Got rid of the configure check for sys/sysctl.h (it wasn't used and was
3423 causing a problem on some systems). Also improved the
3424 broken-largefile-locking test to try to avoid failure due to an NFS
3427 - Fixed a compile problem on systems that don't define `AI_NUMERICHOST`.
3429 - Fixed a compile problem in the popt source for compilers that don't support

3441 # NEWS for rsync 2.6.1 (26 Apr 2004)
3443 ## Changes in this version:
3445 ### PROTOCOL NUMBER:
3447 - The protocol number was changed to 28.
3451 - Paths sent to an rsync daemon are more thoroughly sanitized when chroot is
3452 not used. If you're running a non-read-only rsync daemon with chroot
3453 disabled, **please upgrade**, ESPECIALLY if the user privs you run rsync
3454 under is anything above `nobody`.
3458 - Lower memory use, more optimal transfer of data over the socket, and lower
3459 CPU usage (see the INTERNAL section for details).
3461 - The `RSYNC_PROXY` environment variable can now contain a `USER:PASS@` prefix
3462 before the `HOST:PORT` information. (Bardur Arantsson)
3464 - The `--progress` output now mentions how far along in the transfer we are,
3465 including both a count of files transferred and a percentage of the total
3466 file-count that we've processed. It also shows better
3467 current-rate-of-transfer and remaining-transfer-time values.
3469 - Documentation changes now attempt to describe some often mis- understood
3470 features more clearly.
3474 - When `-x` (`--one-file-system`) is combined with `-L` (`--copy-links`) or
3475 `--copy-unsafe-links,` no symlinked files are skipped, even if the referent
3476 file is on a different filesystem.
3478 - The `--link-dest` code now works properly for a non-root user when (1) the
3479 UIDs of the source and destination differ and `-o` was specified, or (2)
3480 when the group of the source can't be used on the destination and `-g` was
3483 - Fixed a bug in the handling of `-H` (hard-links) that might cause the
3484 expanded PATH/NAME value of the current item to get overwritten (due to an
3485 expanded-name caching bug).
3487 - We now reset the `new data has been sent` flag at the start of each file we
3488 send. This makes sure that an interrupted transfer with the `--partial`
3489 option set doesn't keep a shorter temp file than the current basis file when
3490 no new data has been transferred over the wire for that file.
3492 - Fixed a byte-order problem in `--batch-mode` on big-endian machines. (Jay
3495 - When using `--cvs-exclude`, the exclude items we get from a per-directory's
3496 .cvsignore file once again only affect that one directory (not all following
3497 directories too). The items are also now properly word-split and parsed
3498 without any +/- prefix parsing.
3500 - When specifying the USER@HOST: prefix for a file, the USER part can now
3501 contain an '@', if needed (i.e. the last '@' is used to find the HOST, not
3504 - Fixed some bugs in the handling of group IDs for non-root users: (1) It
3505 properly handles a group that the sender didn't have a name for (it would
3506 previously skip changing the group on any files in that group). (2) If
3507 `--numeric-ids` is used, rsync no longer attempts to set groups that the
3508 user doesn't have the permission to set.
3510 - Fixed the `refuse options` setting in the rsyncd.conf file.
3512 - Improved the `-x` (`--one-file-system`) flag's handling of any mount- point
3513 directories we encounter. It is both more optimal (in that it no longer does
3514 a useless scan of the contents of the mount- point dirs) and also fixes a
3515 bug where a remapped mount of the original filesystem could get discovered
3516 in a subdir we should be ignoring.
3518 - Rsync no longer discards a double-slash at the start of a filename when
3519 trying to open the file. It also no longer constructs names that start with
3520 a double slash (unless the user supplied them).
3522 - Path-specifying options to a daemon should now work the same with or without
3523 chroot turned on. Previously, such a option (such as `--link-dest`) would
3524 get its absolute path munged into a relative one if chroot was not on,
3525 making that setting fairly useless. Rsync now transforms the path into one
3526 that is based on the module's base dir when chroot is not enabled.
3528 - Fixed a compatibility problem interacting with older rsync versions that
3529 might send us an empty `--suffix` value without telling us that
3530 `--backup-dir` was specified.
3532 - The `hosts allow` option for a daemon-over-remote-shell process now has
3533 improved support for IPv6 addresses and a fix for systems that have a length
3534 field in their socket structs.
3536 - Fixed the ability to request an empty backup `--suffix` when sending files
3539 - Fixed an option-parsing bug when `--files-from` was sent to a server sender.
3543 - Most of the I/O is now buffered, which results in a pretty large speedup
3544 when running under MS Windows. (Craig Barratt)
3546 - Optimizations to the name-handling/comparing code have made some significant
3547 reductions in user-CPU time for large file sets.
3549 - Some cleanup of the variable types make the code more consistent.
3551 - Reduced memory requirements of hard link preservation. (J.W. Schultz)
3553 - Implemented a new algorithm for hard-link handling that speeds up the code
3554 significantly. (J.W. Schultz and Wayne Davison)
3556 - The `--hard-link` option now uses the first existing file in the group of
3557 linked files as the basis for the transfer. This prevents the sub-optimal
3558 transfer of a file's data when a new hardlink is added on the sending side
3559 and it sorts alphabetically earlier in the list than the files that are
3560 already present on the receiving side.
3562 - Dropped support for protocol versions less than 20 (2.3.0 released 15 Mar
3563 1999) and activated warnings for protocols less than 25 (2.5.0 released 23
3564 Aug 2001). (Wayne Davison and J.W. Schultz, severally)
3566 - More optimal data transmission for `--hard-links` (protocol 28).
3568 - More optimal data transmission for `--checksum` (protocol 28).
3570 - Less memory is used when `--checksum` is specified.
3572 - Less memory is used in the file list (a per-file savings).
3574 - The generator is now better about not modifying the file list during the
3575 transfer in order to avoid a copy-on-write memory bifurcation (on systems
3576 where fork() uses shared memory). Previously, rsync's shared memory would
3577 slowly become unshared, resulting in real memory usage nearly doubling on
3578 the receiving side by the end of the transfer. Now, as long as permissions
3579 are being preserved, the shared memory should remain that way for the entire
3582 - Changed hardlink info and `file_struct` + strings to use allocation pools.
3583 This reduces memory use for large file-sets and permits freeing memory to
3584 the OS. (J.W. Schultz)
3586 - The 2 pipes used between the receiver and generator processes (which are
3587 forked on the same machine) were reduced to 1 pipe and the protocol improved
3588 so that (1) it is now impossible to have the `redo` pipe fill up and hang
3589 rsync, and (2) trailing messages from the receiver don't get lost on their
3590 way through the generator over to the sender (which mainly affected
3591 hard-link messages and verbose `--stats` output).
3593 - Improved the internal uid/gid code to be more portable and a little more
3596 - The device numbers sent when using `--devices` are now sent as separate
3597 major/minor values with 32-bit accuracy (protocol 28). Previously, the
3598 copied devices were sent as a single 32-bit number. This will make
3599 inter-operation of 64-bit binaries more compatible with their 32-bit
3600 brethren (with both ends of the connection are using protocol 28). Note that
3601 optimizations in the binary protocol for sending the device numbers often
3602 results in fewer bytes being used than before, even though more precision is
3605 - Some cleanup of the exclude/include structures and its code made things
3606 clearer (internally), simpler, and more efficient.
3608 - The reading & writing of the file-list in batch-mode is now handled by the
3609 same code that sends & receives the list over the wire. This makes it much
3610 easier to maintain. (Note that the batch code is still considered to be
3615 - The configure script now accepts `--with-rsyncd-conf=PATH` to override the
3616 default value of the /etc/rsyncd.conf file.
3618 - Fixed configure bug when running `./configure --disable-ipv6`.
3620 - Fixed compilation problem on Tru64 Unix (having to do with `sockaddr.sa_len`
3621 and `sockaddr.sin_len`).
3623 ### DEVELOPER RELATED:
3625 - Fixed `make test` bug when build dir is not the source dir.
3627 - Added a couple extra diffs in the `patches` dir, removed the ones that got
3628 applied, and rebuilt the rest.

3633 # NEWS for rsync 2.6.0 (1 Jan 2004)
3635 ## Changes in this version:
3637 ### PROTOCOL NUMBER:
3639 - The protocol number was changed to 27. The maximum accepted protocol number
3640 was increased from 30 to 40.
3644 - `ssh` is now the default remote shell for rsync. If you want to change this,
3645 configure like this: `./configure --with-rsh=rsh`.
3647 - Added `--files-from`, `--no-relative`, `--no-implied-dirs`, and `--from0`.
3648 Note that `--from0` affects the line-ending character for all the files read
3649 by the `--*-from` options. (Wayne Davison)
3651 - Length of csum2 is now per-file starting with protocol version
3654 - Per-file dynamic block size is now sqrt(file length). The per-file checksum
3655 size is determined according to an algorithm provided by Donovan Baarda
3656 which reduces the probability of rsync algorithm corrupting data and falling
3657 back using the whole md4 checksums. (J.W. Schultz, Donovan Baarda)
3659 - The `--stats` option no longer includes the (debug) malloc summary unless
3660 the verbose option was specified at least twice.
3662 - Added a new error/warning code for when files vanish from the sending side.
3663 Made vanished source files not interfere with the file-deletion pass when
3664 `--delete-after` was specified.
3666 - Various trailing-info sections are now preceded by a newline.
3670 - Fixed several exclude/include matching bugs when using wild-cards. This has
3671 a several user-visible effects, all of which make the matching more
3672 consistent and intuitive. This should hopefully not cause anyone problems
3673 since it makes the matching work more like what people are expecting. (Wayne
3676 - A pattern with a `**` no longer causes a `*` to match slashes. For example,
3677 with `/*/foo/**`, `foo` must be 2 levels deep. [If your string has BOTH `*`
3678 and `**` wildcards, changing the `*` wildcards to `**` will provide the old
3679 behavior in all versions.]
3681 - `**/foo` now matches at the base of the transfer (like /foo does). [Use
3682 `/**/foo` to get the old behavior in all versions.]
3684 - A non-anchored wildcard term floats to match beyond the base of the
3685 transfer. E.g. `CVS/R*` matches at the end of the path, just like the
3686 non-wildcard term `CVS/Root` does. [Use `/CVS/R*` to get the old behavior in
3689 - Including a `**` in the match term causes it to be matched against the
3690 entire path, not just the name portion, even if there aren't any interior
3691 slashes in the term. E.g. `foo**bar` would exclude `/path/foo-bar` (just
3692 like before) as well as `/foo-path/baz-bar` (unlike before). [Use `foo*bar`
3693 to get the old behavior in all versions.]
3695 - The exclude list specified in the daemon's config file is now properly
3696 applied to the pulled items no matter how deep the user's file-args are in
3697 the source tree. (Wayne Davison)
3699 - For protocol version >= 27, `mdfour_tail()` is called when the block size
3700 (including `checksum_seed`) is a multiple of 64. Previously it was not
3701 called, giving the wrong MD4 checksum. (Craig Barratt)
3703 - For protocol version >= 27, a 64 bit bit counter is used in mdfour.c as
3704 required by the RFC. Previously only a 32 bit bit counter was used, causing
3705 incorrect MD4 file checksums for file sizes >= 512MB - 4. (Craig Barratt)
3707 - Fixed a crash bug when interacting with older rsync versions and multiple
3708 files of the same name are destined for the same dir. (Wayne Davison)
3710 - Keep tmp names from overflowing MAXPATHLEN.
3712 - Make `--link-dest` honor the absence of `-p`, `-o`, and `-g`.
3714 - Made rsync treat a trailing slash in the destination in a more consistent
3717 - Fixed file I/O error detection. (John Van Essen)
3719 - Fixed bogus `malformed address {hostname}` message in rsyncd log when
3720 checking IP address against hostnames from `hosts allow` and `hosts deny`
3721 parameters in config file.
3723 - Print heap statistics when verbose >= 2 instead of when >= 1.
3725 - Fixed a compression (`-z`) bug when syncing a mostly-matching file that
3726 contains already-compressed data. (Yasuoka Masahiko and Wayne Davison)
3728 - Fixed a bug in the `--backup` code that could cause deleted files to not get
3731 - When the backup code makes new directories, create them with mode 0700
3732 instead of 0755 (since the directory permissions in the backup tree are not
3733 yet copied from the main tree).
3735 - Call setgroups() in a more portable manner.
3737 - Improved file-related error messages to better indicate exactly what
3738 pathname failed. (Wayne Davison)
3740 - Fixed some bugs in the handling of `--delete` and `--exclude` when using the
3741 `--relative` (`-R`) option. (Wayne Davison)
3743 - Fixed bug that prevented regular files from replacing special files and
3744 caused a directory in `--link-dest` or `--compare-dest` to block the
3745 creation of a file with the same path. A directory still cannot be replaced
3746 by a regular file unless `--delete` specified. (J.W. Schultz)
3748 - Detect and report when open or opendir succeed but read and readdir fail
3749 caused by network filesystem issues and truncated files. (David Norwood,
3750 Michael Brown, J.W. Schultz)
3752 - Added a fix that should give ssh time to restore the tty settings if the
3753 user presses Ctrl-C at an ssh password prompt.
3757 - Eliminated vestigial support for old versions that we stopped supporting.
3760 - Simplified some of the option-parsing code. (Wayne Davison)
3762 - Some cleanup made to the exclude code, as well as some new defines added to
3763 enhance readability. (Wayne Davison)
3765 - Changed the protocol-version code so that it can interact at a lower
3766 protocol level than the maximum supported by both sides. Added an
3767 undocumented option, `--protocol=N`, to force the value we advertise to the
3768 other side (primarily for testing purposes). (Wayne Davison)

3787 ## Changes in this version:
3791 - The `--delete-after` option now implies `--delete`. (Wayne Davison)
3793 - The `--suffix` option can now be used with `--backup-dir`. (Michael
3796 - Combining `::` syntax with the `--rsh`/`-e` option now uses the specified
3797 remote-shell as a transport to talk to a (newly-spawned) server-daemon. This
3798 allows someone to use daemon features, such as modules, over a secure
3799 protocol, such as ssh. (JD Paul)
3801 - The rsync:// syntax for daemon connections is now accepted in the
3804 - If the file name given to `--include-from` or `--exclude-from` is `-`, rsync
3805 will read from standard input. (J.W. Schultz)
3807 - New option `--link-dest` which is like `--compare-dest` except that
3808 unchanged files are hard-linked in to the destination directory. (J.W.
3811 - Don't report an error if an excluded file disappears during an rsync run.
3812 (Eugene Chupriyanov and Bo Kersey)
3814 - Added .svn to `--cvs-exclude` list to support subversion. (Jon Middleton)
3816 - Properly support IPv6 addresses in the rsyncd.conf `hosts allow` and `hosts
3817 deny` fields. (Hideaki Yoshifuji)
3819 - Changed exclude file handling to permit DOS or MAC style line terminations.
3822 - Ignore errors from chmod when `-p`/`-a`/`--preserve-perms` is not set.
3827 - Fix `forward name lookup failed` errors on AIX 4.3.3. (John L. Allen, Martin
3830 - Generate each file's rolling-checksum data as we send it, not in a separate
3831 (memory-eating) pass before hand. This prevents timeout errors on really
3832 large files. (Stefan Nehlsen)
3834 - Fix compilation on Tru64. (Albert Chin, Zoong Pham)
3836 - Better handling of some client-server errors. (Martin Pool)
3838 - Fixed a crash that would occur when sending a list of files that contains a
3839 duplicate name (if it sorts to the end of the file list) and using
3840 `--delete`. (Wayne Davison)
3842 - Fixed the file-name duplicate-removal code when dealing with multiple dups
3843 in a row. (Wayne Davison)
3845 - Fixed a bug that caused rsync to lose the exit status of its child processes
3846 and sometimes return an exit code of 0 instead of showing an error. (David
3847 R. Staples, Dave Dykstra)
3849 - Fixed bug in `--copy-unsafe-links` that caused it to be completely broken.
3852 - Prevent infinite recursion in cleanup code under certain circumstances.
3853 (Sviatoslav Sviridov and Marc Espie)
3855 - Fixed a bug that prevented rsync from creating intervening directories when
3856 `--relative-paths`/`-R` is set. (Craig Barratt)
3858 - Prevent `Connection reset by peer` messages from Cygwin. (Randy O'Meara)
3862 - Many code cleanups and improved internal documentation. (Martin Pool, Nelson
3865 - Portability fixes. (Dave Dykstra and Wayne Davison)
3867 - More test cases. (Martin Pool)
3869 - Some test-case fixes. (Brian Poole, Wayne Davison)
3871 - Updated included popt to the latest vendor drop, version 1.6.4. (Jos
3874 - Updated config.guess and config.sub to latest versions; this means rsync
3875 should build on more platforms. (Paul Green)

3880 # NEWS for rsync 2.5.5, aka Snowy River (2 Apr 2002)
3882 ## Changes in this version:
3886 - With `--progress`, when a transfer is complete show the time taken;
3887 otherwise show expected time to complete. (Cameron Simpson)
3889 - Make `make install-strip` works properly, and `make install` accepts a
3890 DESTDIR variable for help in building binary packages. (Peter
3891 Breitenlohner, Greg Louis)
3893 - If configured with `--enable-maintainer-mode`, then on receipt of a fatal
3894 signal rsync will try to open an xterm running gdb, similarly to Samba's
3895 `panic action` or GNOME's bug-buddy. (Martin Pool)
3899 - Fix situation where failure to fork (e.g. because out of process slots)
3900 would cause rsync to kill all processes owned by the current user. Yes,
3901 really! (Paul Haas, Martin Pool)
3903 - Fix test suite on Solaris. (Jos Backus, Martin Pool)
3905 - Fix minor memory leak in socket code. (Dave Dykstra, Martin Pool.)
3907 - Fix `--whole-file` problem that caused it to be the default even for remote
3908 connections. (Martin Pool, Frank Schulz)

3946 process after changing uid and gid. (Ethan Benson) (Debian bug
3947 #132272, CVE CAN-2002-0080)
3951 - Fix zlib double-free bug. (Owen Taylor, Mark J Cox) (CVE CAN-2002-0059)
3953 - Fixed problem that in many cases caused the error message unexpected read
3954 size of 0 in `map_ptr` and resulted in the wrong data being copied.
3956 - Fixed compilation errors on some systems caused by the use of `unsigned
3959 - Fixed problem on systems such as Sunos4 that do not support realloc on a
3960 NULL pointer; error was 'out of memory in "flist_expand"'.
3962 - Fix for rsync server processes hanging around after the client unexpectedly
3963 disconnects. (Colin Walters) (Debian bug #128632)
3965 - Cope with BSD systems on which mkdir() will not accept a trailing slash.
3969 - Merge in changes from zlib 1.1.2 to zlib 1.1.3. (Note that rsync still uses
3970 a custom version of zlib; you can not just link against a system library.
3971 See zlib/README.rsync)
3973 - Command to initiate connections is only shown with `-vv`, rather than `-v`
3974 as in 2.5.2. Output from plain `-v` is more similar to what was historically
3975 used so as not to break scripts that try to parse the output.
3977 - Added `--no-whole-file` and `--no-blocking-io` options (Dave Dykstra)
3979 - Made the `--write-batch` and `--read-batch` options actually work and added
3980 documentation in the man page (Jos Backus)

4101 - Include/exclude cluestick: with `-vv`, print out whether files are included
4102 or excluded and why.
4104 - Many error messages have more friendly explanations and more details.
4106 - Manual page improvements plus scanty protocol documentation.
4108 - When running as `--daemon` in the background and using a `log file`
4109 rsyncd.conf directive, close the log file every time it is open when going
4110 to sleep on the socket. This allows the log file to get cleaned out by
4113 - Change to using libpopt rather than getopt for processing options. This
4114 makes the code cleaner and the behaviour more consistent across platforms.
4115 popt is included and built if not installed on the platform.
4117 - More details in `--version`, including note about whether 64-bit files,
4118 symlinks and hardlinks are supported.
4120 - MD4 code may use less CPU cycles.
4122 - Use mkstemp on systems where it is secure. If we use mktemp, explain that we
4123 do it in a secure way.
4125 - `--whole-file` is the default when source and target are on the local
4130 - Fix for various bugs causing rsync to hang.
4132 - Attempt to fix Large File Summit support on AIX.
4134 - Attempt to fix error handling lockup bug.
4136 - Give a non-0 exit code if **any** of the files we have been asked to
4137 transfer fail to transfer.
4139 - For log messages containing ridiculously long strings that might overflow a
4140 buffer rsync no longer aborts, but rather prints an ellipsis at the end of
4141 the string. (Patch from Ed Santiago.)
4145 - Improved support for UNICOS (tested on Cray T3E and Cray SV1)
4147 - autoconf2.52 (or later) is now required to rebuild the autoconf scripts. It
4148 is not required to simply build rsync.
