1 NEWS for rsync 2.6.5 (1 Jun 2005)
2 Protocol: 29 (unchanged)
7 - Non-printable chars in filenames are now output using backslash-
8 escaped characters rather than '?'s. Any non-printable character is
9 output using 3 digits of octal (e.g. "\n" -> "\012"), and a backslash
10 is now output as "\\". Rsync also uses your locale setting, which
11 can make it treat fewer high-bit characters as non-printable.
13 - If rsync received an empty file-list when pulling files, it would
14 output a "nothing to do" message and exit with a 0 (success) exit
15 status, even if the remote rsync returned an error (it did not do
16 this under the same conditions when pushing files). This was changed
17 to make the pulling behavior the same as the pushing behavior: we
18 now do the normal end-of-run outputting (depending on options) and
19 exit with the appropriate exit status.
23 - A crash bug was fixed when a daemon had its "path" set to "/", did
24 not have chroot enabled, and used some anchored excludes in the
27 - Fixed a bug in the transfer of a single file when -H is specified
28 (rsync would either infinite loop or perhaps crash).
30 - Fixed a case where the generator might try (and fail) to tweak the
31 write-permissions of a read-only directory in list-only mode (this
32 only caused an annoying warning message).
34 - If --compare-dest or --link-dest uses a locally-copied file as the
35 basis for an updated version, log this better when --verbose or -i
38 - Fixed the accidental disabling of --backup during the --delete-after
41 - Restored the ability to use the --address option in client mode (in
42 addition to its use in daemon mode).
44 - Make sure that some temporary progress information from the delete
45 processing does not get left on the screen when it is followed by a
48 - When --existing skips a directory with extra verbosity, refer to it
49 as a "directory", not a "file".
51 - When transferring a single file to a different-named file, any
52 generator messages that are source-file related no longer refer to
53 the file by the destination filename.
55 - Fixed a bug where hard-linking a group of files might fail if the
56 generator hasn't created a needed destination directory yet.
58 - Fixed a bug where a hard-linked group of files that is newly-linked
59 to a file in a --link-dest dir doesn't link the files from the rest
62 - When deleting files with the --one-file-system (-x) option set, rsync
63 no longer tries to remove files from inside a mount-point on the
64 receiving side. Also, we don't complain about being unable to remove
67 - Fixed a compatibility problem when using --cvs-ignore (-C) and
68 sending files to an older rsync without using --delete.
70 - Make sure that a "- !" or "+ !" include/exclude pattern does not
71 trigger the list-clearing action that is reserved for "!".
73 - Avoid a timeout in the generator when the sender/receiver aren't
74 handling the generator's checksum output quickly enough.
76 - Fixed the omission of some directories in the delete processing when
77 --relative (-R) was combined with a source path that had a trailing
80 - Fixed a case where rsync would erroneously delete some files and then
81 re-transfer them when the options --relative (-R) and --recursive
82 (-r) were both enabled (along with --delete) and a source path had a
85 - Make sure that --max-size doesn't affect a device or a symlink.
87 - Make sure that a system with a really small MAXPATHLEN does not cause
88 the buffers in readfd_unbuffered() to be too small to receive normal
89 messages. (This mainly affected Cygwin.)
91 - If a source pathname ends with a filename of "..", treat it as if
92 "../" had been specified (so that we don't copy files to the parent
93 dir of the destination).
95 - If --delete is combined with a file-listing rsync command (i.e. no
96 transfer is happening), avoid outputting a warning that we couldn't
99 - If --stats is specified with --delete-after, ensure that all the
100 "deleting" messages are output before the statistics.
102 - Improved one "if" in the deletion code that was only checking errno
103 for ENOTEMPTY when it should have also been checking for EEXIST (for
104 compatibility with OS variations).
108 - Added the --only-write-batch=FILE option that may be used (instead
109 of --write-batch=FILE) to create a batch file without doing any
110 actual updating of the destination. This allows you to divert all
111 the file-updating data away from a slow data link (as long as you
112 are pushing the data to the remote server when creating the batch).
114 - When the generator is taking a long time to fill up its output buffer
115 (e.g. if the transferred files are few, small, or missing), it now
116 periodically flushes the output buffer so that the sender/receiver
117 can get started on the files sooner rather than later.
119 - Improved the keep-alive code to handle a long silence between the
120 sender and the receiver that can occur when the sender is receiving
121 the checksum data for a large file.
123 - Improved the auth-errors that are logged by the daemon to include
124 some information on why the authorization failed: wrong user,
125 password mismatch, etc. (The client-visible message is unchanged!)
127 - Improved the client's handling of an "@ERROR" from a daemon so that
128 it does not complain about an unexpectedly closed socket (since we
129 really did expect the socket to close).
131 - If the daemon can't open the log-file specified in rsyncd.conf, fall
132 back to using syslog and log an appropriate warning. This is better
133 than what was typically a totally silent (and fatal) failure (since a
134 daemon is not usually run with the --no-detach option that was
135 necessary to see the error on stderr).
137 - The man pages now consistently refer to an rsync daemon as a "daemon"
138 instead of a "server" (to distinguish it from the server process in a
139 non-daemon transfer).
141 - Made a small change to the rrsync script (restricted rsync -- in the
142 support dir) to make a read-only server reject all --remove-* options
143 when sending files (to future-proof it against the possibility of
144 other similar options being added at some point).
148 - Rsync now calls setlocale(LC_CTYPE, ""). This enables isprint() to
149 better discern which filename characters need to be escaped in
150 messages (which should result in fewer escaped characters in some
153 - Improved the naming of the log-file open/reopen/close functions.
155 - Removed some protocol-compatibility code that was only needed to help
156 someone running a pre-release of 2.6.4.
160 - Added configure option "--disable-locale" to disable any use of
161 setlocale() in the binary.
163 - Fixed a bug in the SUPPORT{,_HARD}_LINKS #defines which prevented
164 rsync from being built without symlink or hard-link support.
166 - Only #define HAVE_REMSH if it is going to be set to 1.
168 - Configure now disables the use of mkstemp() under HP-UX (since they
169 refuse to fix its broken handling of large files).
171 - Configure now explicitly checks for the lseek64() function so that
172 the code can use HAVE_LSEEK64 instead of inferring lseek64()'s
173 presence based on the presence of the off64_t type.
175 - Configure no longer mentions the change in the default remote-shell
176 (from rsh to ssh) that occurred for the 2.6.0 release.
178 - Some minor enhancements to the test scripts.
180 - Added a few new *.diff files to the patches dir, including a patch
181 that enables the optional copying of extended attributes.
184 NEWS for rsync 2.6.4 (30 March 2005)
185 Protocol: 29 (changed)
190 - When rsync deletes a directory and outputs a verbose message about
191 it, it now appends a trailing slash to the name instead of (only
192 sometimes) outputting a preceding "directory " string.
194 - The --stats output will contain file-list time-statistics if both
195 sides are 2.6.4, or if the local side is 2.6.4 and the files are
196 being pushed (since the stats come from the sending side).
197 (Requires protocol 29 for a pull.)
199 - The "%o" (operation) log-format escape now has a third value (besides
200 "send" and "recv"): "del." (with trailing dot to make it 4 chars).
201 This changes the way deletions are logged in the daemon's log file.
203 - When the --log-format option is combined with --verbose, rsync now
204 avoids outputting the name of the file twice in most circumstances.
205 As long as the --log-format item does not refer to any post-transfer
206 items (such as %b or %c), the --log-format message is output prior to
207 the transfer, so --verbose is now the equivalent of a --log-format of
208 '%n%L' (which outputs the name and any link info). If the log output
209 must occur after the transfer to be complete, the only time the name
210 is also output prior to the transfer is when --progress was specified
211 (so that the name will precede the progress stats, and the full
212 --log-format output will come after).
214 - Non-printable characters in filenames are replaced with a '?' to
215 avoid corrupting the screen or generating empty lines in the output.
219 - Restore the list-clearing behavior of "!" in a .cvsignore file (2.6.3
220 was only treating it as a special token in an rsync include/exclude
223 - The combination of --verbose and --dry-run now mentions the full list
224 of changes that would be output without --dry-run.
226 - Avoid a mkdir warning when removing a directory in the destination
227 that already exists in the --backup-dir.
229 - An OS that has a binary mode for its files (such as cygwin) needed
230 setmode(fd, O_BINARY) called on the temp-file we opened with
231 mkstemp(). (Fix derived from the cygwin's 2.6.3 rsync package.)
233 - Fixed a potential hang when verbosity is high, the client side is
234 the sender, and the file-list is large.
236 - Fixed a potential protocol-corrupting bug where the generator could
237 merge a message from the receiver into the middle of a multiplexed
238 packet of data if only part of that data had been written out to the
239 socket when the message from the generator arrived.
241 - We now check if the OS doesn't support using mknod() for creating
242 FIFOs and sockets, and compile-in some compatibility code using
243 mkfifo() and socket() when necessary.
245 - Fixed an off-by-one error in the handling of --max-delete=N. Also,
246 if the --max-delete limit is exceeded during a run, we now output a
247 warning about this at the end of the run and exit with a new error
250 - One place in the code wasn't checking if fork() failed.
252 - The "ignore nonreadable" daemon parameter used to erroneously affect
253 readable symlinks that pointed to a non-existent file.
255 - If the OS does not have lchown() and a chown() of a symlink will
256 affect the referent of a symlink (as it should), we no longer try
257 to set the user and group of a symlink.
259 - The generator now properly runs the hard-link loop and the dir-time
260 rewriting loop after we're sure that the redo phase is complete.
262 - When --backup was specified with --partial-dir=DIR, where DIR is a
263 relative path, the backup code was erroneously trying to backup a
264 file that was put into the partial-dir.
266 - If a file gets resent in a single transfer and the --backup option is
267 enabled along with --inplace, rsync no longer performs a duplicate
268 backup (it used to overwrite the first backup with the failed file).
270 - One call to flush_write_file() was not being checked for an error.
272 - The --no-relative option was not being sent from the client to a
275 - If an rsync daemon specified "dont compress = ..." for a file and the
276 client tried to specify --compress, the libz code was not handling a
277 compression level of 0 properly. This could cause a transfer failure
278 if the block-size for a file was large enough (e.g. rsync might have
279 exited with an error for large files).
281 - Fixed a bug that would sometimes surface when using --compress and
282 sending a file with a block-size larger than 64K (either manually
283 specified, or computed due to the file being really large). Prior
284 versions of rsync would sometimes fail to decompress the data
285 properly, and thus the transferred file would fail its verification.
287 - If a daemon can't open the specified log file (i.e. syslog is not
288 being used), die without crashing. We also output an error about
289 the failure on stderr (which will only be seen if --no-detach was
290 specified) and exit with a new error code (6).
292 - A local transfer no longer duplicates all its include/exclude options
293 (since the forked process already has a copy of the exclude list,
294 there's no need to send them a set of duplicates).
296 - When --progress is specified, the output of items that the generator
297 is creating (e.g. dirs, symlinks) is now integrated into the progress
298 output without overlapping it. (Requires protocol 29.)
300 - When --timeout is specified, lulls that occur in the transfer while
301 the generator is doing work that does not generate socket traffic
302 (looking for changed files, deleting files, doing directory-time
303 touch-ups, etc.) will cause a new keep-alive packet to be sent that
304 should keep the transfer going as long as the generator continues to
305 make progress. (Requires protocol 29.)
307 - The stat size of a device is not added to the total file size of the
308 items in the transfer (the size might be undefined on some OSes).
310 - Fixed a problem with refused-option messages sometimes not making it
311 back to the client side when a remote --files-from was in effect and
312 the daemon was the receiver.
314 - The --compare-dest option was not updating a file that differed in
315 (the preserved) attributes from the version in the compare-dest DIR.
317 - When rsync is copying files into a write-protected directory, fixed
318 the change-report output for the directory so that we don't report
319 an identical directory as changed.
323 - Rsync now supports popt's option aliases, which means that you can
324 use /etc/popt and/or ~/.popt to create your own option aliases.
326 - Added the --delete-during (--del) option which will delete files
327 from the receiving side incrementally as each directory in the
328 transfer is being processed. This makes it more efficient than the
329 default, before-the-transfer behavior, which is now also available as
330 --delete-before (and is still the default --delete-WHEN option that
331 will be chosen if --delete or --delete-excluded is specified without
332 a --delete-WHEN choice). All the --del* options infer --delete, so
333 an rsync daemon that refuses "delete" will still refuse to allow any
334 file-deleting options (including the new --remove-sent-files option).
336 - All the --delete-WHEN options are now more memory efficient:
337 Previously an duplicate set of file-list objects was created on the
338 receiving side for the entire destination hierarchy. The new
339 algorithm only creates one directory of objects at a time (for files
340 inside the transfer).
342 - Added the --copy-dest option, which works like --link-dest except
343 that it locally copies identical files instead of hard-linking them.
345 - Added support for specifying multiple --compare-dest, --copy-dest, or
346 --link-dest options, but only of a single type. (Promoted from the
347 patches dir and enhanced.) (Requires protocol 29.)
349 - Added the --max-size option. (Promoted from the patches dir.)
351 - The daemon-mode options are now separated from the normal rsync
352 options so that they can't be mixed together. This makes it
353 impossible to start a daemon that has improper default option values
354 (which could cause problems when a client connects, such as hanging
357 - The --bwlimit option may now be used in combination with --daemon
358 to specify both a default value for the daemon side and a value
359 that cannot be exceeded by a user-specified --bwlimit option.
361 - Added the "port" parameter to the rsyncd.conf file. (Promoted from
362 the patches dir.) Also added "address". The command-line options
363 take precedence over a config-file option, as expected.
365 - In _exit_cleanup(): when we are exiting with a partially-received
366 file, we now flush any data in the write-cache before closing the
369 - The --inplace support was enhanced to work with --compare-dest,
370 --link-dest, and (the new) --copy-dest options. (Requires protocol
373 - Added the --dirs (-d) option for an easier way to copy directories
374 without recursion. Any directories that are encountered are created
375 on the destination. Specifying a directory with a trailing slash
376 copies its immediate contents to the destination.
378 - The --files-from option now implies --dirs (-d).
380 - Added the --list-only option, which is mainly a way for the client to
381 put the server into listing mode without needing to resort to any
382 internal option kluges (e.g. the age-old use of "-r --exclude="/*/*"
383 for a non-recursive listing). This option is used automatically
384 (behind the scenes) when a modern rsync speaks to a modern daemon,
385 but may also be specified manually if you want to force the use of
386 the --list-only option over a remote-shell connection.
388 - Added the --omit-dir-times (-O) option, which will avoid updating
389 the modified time for directories when --times was specified. This
390 option will avoid an extra pass through the file-list at the end of
391 the transfer (to tweak all the directory times), which may provide
392 an appreciable speedup for a really large transfer. (Promoted from
395 - Added the --filter (-f) option and its helper option, -F. Filter
396 rules are an extension to the existing include/exclude handling
397 that also supports nested filter files as well as per-directory
398 filter files (like .cvsignore, but with full filter-rule parsing).
399 This new option was chosen in order to ensure that all existing
400 include/exclude processing remained 100% compatible with older
401 versions. Protocol 29 is needed for full filter-rule support, but
402 backward-compatible rules work with earlier protocol versions.
403 (Promoted from the patches dir and enhanced.)
405 - Added the --delay-updates option that puts all updated files into
406 a temporary directory (by default ".~tmp~", but settable via the
407 --partial-dir=DIR option) until the end of the transfer. This
408 makes the updates a little more atomic for a large transfer.
410 - If rsync is put into the background, any output from --progress is
413 - Documented the "max verbosity" setting for rsyncd.conf. (This
414 setting was added a couple releases ago, but left undocumented.)
416 - The sender and the generator now double-check the file-list index
417 they are given, and refuse to try to do a file transfer on a
418 non-file index (since that would indicate that something had gone
421 - Added the --itemize-changes (-i) option, which is a way to output a
422 more detailed list of what files changed and in what way. The effect
423 is the same as specifying a --log-format of "%i %n%L" (see both the
424 rsync and rsyncd.conf manpages). Works with --dry-run too.
426 - Added the --fuzzy (-y) option, which attempts to find a basis file
427 for a file that is being created from scratch. The current algorithm
428 only looks in the destination directory for the created file, but it
429 does attempt to find a match based on size/mod-time (in case the file
430 was renamed with no other changes) as well as based on a fuzzy
431 name-matching algorithm. This option requires protocol 29 because it
432 needs the new file-sorting order. (Promoted from patches dir and
433 enhanced.) (Requires protocol 29.)
435 - Added the --remove-sent-files option, which lets you move files
438 - The hostname in HOST:PATH or HOST::PATH may now be an IPv6 literal
439 enclosed in '[' and ']' (e.g. "[::1]"). (We already allowed IPv6
440 literals in the rsync://HOST:PORT/PATH format.)
442 - When rsync recurses to build the file list, it no longer keeps open
443 one or more directory handles from the dir's parent dirs.
445 - When building under windows, the default for --daemon is now to
446 avoid detaching, requiring the new --detach option to force rsync
449 - The --dry-run option can now be combined with either --write-batch or
450 --read-batch, allowing you to run a do-nothing test command to see
451 what would happen without --dry-run.
453 - The daemon's "read only" config item now sets an internal read_only
454 variable that makes extra sure that no write/delete calls on the
455 read-only side can succeed.
457 - The log-format % escapes can now have a numeric field width in
458 between the % and the escape letter (e.g. "%-40n %08p").
460 - Improved the option descriptions in the --help text.
464 - Added atomic-rsync to the support dir: a perl script that will
465 transfer some files using rsync, and then move the updated files into
466 place all at once at the end of the transfer. Only works when
467 pulling, and uses --link-dest and a parallel hierarchy of files to
470 - Added mnt-excl to the support dir: a perl script that takes the
471 /proc/mounts file and translates it into a set of excludes that will
472 exclude all mount points (even mapped mounts to the same disk). The
473 excludes are made relative to the specified source dir and properly
476 - Added savetransfer.c to the support dir: a C program that can make
477 a copy of all the data that flows over the wire. This lets you test
478 for data corruption (by saving the data on both the sending side and
479 the receiving side) and provides one way to debug a protocol error.
481 - Added rrsync to the support dir: this is an updated version of Joe
482 Smith's restricted rsync perl script. This helps to ensure that only
483 certain rsync commands can be run by an ssh invocation.
487 - Added better checking of the checksum-header values that come over
490 - Merged a variety of file-deleting functions into a single function so
491 that it is easier to maintain.
493 - Improved the type of some variables (particularly blocksize vars) for
494 consistency and proper size.
496 - Got rid of the uint64 type (which we didn't need).
498 - Use a slightly more compatible set of core #include directives.
500 - Defined int32 in a way that ensures that the build dies if we can't
501 find a variable with at least 32 bits.
503 PROTOCOL DIFFERENCES FOR VERSION 29:
505 - A 16-bit flag-word is transmitted after every file-list index. This
506 indicates what is changing between the sender and the receiver. The
507 generator now transmits an index and a flag-word to indicate when
508 dirs and symlinks have changed (instead of producing a message),
509 which makes the outputting of the information more consistent and
510 less prone to screen corruption (because the local receiver/sender is
511 now outputting all the file-change info messages).
513 - If a file is being hard-linked, the ITEM_XNAME_FOLLOWS bit is enabled
514 in the flag-word and the name of the file that was linked immediately
515 follows in vstring format (see below).
517 - If a file is being transferred with an alternate-basis file, the
518 ITEM_BASIS_TYPE_FOLLOWS bit is enabled in the flag-word and a single
519 byte follows, indicating what type of basis file was chosen. If that
520 indicates that a fuzzy-match was selected, the ITEM_XNAME_FOLLOWS bit
521 is set in the flag-word and the name of the match in vstring format
522 follows the basis byte. A vstring is a variable length string that
523 has its size written prior to the string, and no terminating null.
524 If the string is from 1-127 bytes, the length is a single byte. If
525 it is from 128-32767 bytes, the length is written as ((len >> 8) |
526 0x80) followed by (len % 0x100).
528 - The sending of exclude names is done using filter-rule syntax. This
529 means that all names have a prefixed rule indicator, even excludes
530 (which used to be sent as a bare pattern, when possible). The -C
531 option will include the per-dir .cvsignore merge file in the list of
532 filter rules so it is positioned correctly (unlike in some older
535 - Rsync sorts the filename list in a different way: it sorts the subdir
536 names after the non-subdir names for each dir's contents, and it
537 always puts a dir's contents immediately after the dir's name in the
538 list. (Previously an item named "foo.txt" would sort in between
539 directory "foo/" and "foo/bar".)
541 - When talking to a protocol 29 rsync daemon, a list-only request
542 is able to note this before the options are sent over the wire and
543 the new --list-only option is included in the options.
545 - When the --stats bytes are sent over the wire (or stored in a batch),
546 they now include two elapsed-time values: one for how long it took to
547 build the file-list, and one for how long it took to send it over the
548 wire (each expressed in thousandths of a second).
550 - When --delete-excluded is specified with some filter rules (AKA
551 excludes), a client sender will now initiate a send of the rules to
552 the receiver (older protocols used to omit the sending of excludes in
553 this situation since there were no receiver-specific rules that
554 survived --delete-excluded back then). Note that, as with all the
555 filter-list sending, only items that are significant to the other
556 side will actually be sent over the wire, so the filter-rule list
557 that is sent in this scenario is often empty.
559 - An index equal to the file-list count is sent as a keep-alive packet
560 from the generator to the sender, which then forwards it on to the
561 receiver. This normally invalid index is only a valid keep-alive
562 packet if the 16-bit flag-word that follows it contains a single bit
563 (ITEM_IS_NEW, which is normally an illegal flag to appear alone).
565 - A protocol-29 batch file includes a bit for the setting of the --dirs
566 option and for the setting of the --compress option. Also, the shell
567 script created by --write-batch will use the --filter option instead
568 of --exclude-from to capture any filter rules.
572 - Handle an operating system that use mkdev() in place of makedev().
574 - Improved configure to better handle cross-compiling.
577 NEWS for rsync 2.6.3 (30 Sep 2004)
578 Protocol: 28 (unchanged)
583 - A bug in the sanitize_path routine (which affects a non-chrooted
584 rsync daemon) could allow a user to craft a pathname that would get
585 transformed into an absolute path for certain options (but not for
586 file-transfer names). If you're running an rsync daemon with chroot
587 disabled, *please upgrade*, ESPECIALLY if the user privs you run
588 rsync under is anything above "nobody".
590 OUTPUT CHANGES (ATTN: those using a script to parse the verbose output):
592 - Please note that the 2-line footer (output when verbose) now uses the
593 term "sent" instead of "wrote" and "received" instead of "read". If
594 you are not parsing the numeric values out of this footer, a script
595 would be better off using the empty line prior to the footer as the
596 indicator that the verbose output is over.
598 - The output from the --stats option was similarly affected to change
599 "written" to "sent" and "read" to "received".
601 - Rsync ensures that a filename that contains a newline gets mentioned
602 with each newline transformed into a question mark (which prevents a
603 filename from causing an empty line to be output).
605 - The "backed up ..." message that is output when at least 2 --verbose
606 options are specified is now the same both with and without the
611 - Fixed a crash bug that might appear when --delete was used and
612 multiple source directories were specified.
614 - Fixed a 32-bit truncation of the file length when generating the
617 - The --backup code no longer attempts to create some directories
618 over and over again (generating warnings along the way).
620 - Fixed a bug in the reading of the secrets file (by the daemon) and
621 the password file (by the client): the files no longer need to be
622 terminated by a newline for their content to be read in.
624 - If a file has a read error on the sending side or the reconstructed
625 data doesn't match the expected checksum (perhaps due to the basis
626 file changing during the transfer), the receiver will no longer
627 retain the resulting file unless the --partial option was specified.
628 (Note: for the read-error detection to work, neither side can be
629 older than 2.6.3 -- older receivers will always retain the file, and
630 older senders don't tell the receiver that the file had a read
633 - If a file gets resent in a single transfer and the --backup option
634 is enabled, rsync no longer performs a duplicate backup (it used to
635 overwrite the original file in the backup area).
637 - Files specified in the daemon's "exclude" or "exclude from" config
638 items are now excluded from being uploaded (assuming that the module
639 allows uploading at all) in addition to the old download exclusion.
641 - Got rid of a potential hang in the receiver when near the end of a
644 - When using --backup without a --backup-dir, rsync no longer preserves
645 the modify time on directories. This avoids confusing NFS.
647 - When --copy-links (-L) is specified, we now output a separate error
648 for a symlink that has no referent instead of claiming that a file
651 - The --copy-links (-L) option no longer has the side-effect of telling
652 the receiving side to follow symlinks. See the --keep-dirlinks
653 option (mentioned below) for a way to specify that behavior.
655 - Error messages from the daemon server's option-parsing (such as
656 refused options) are now successfully transferred back to the client
657 (the server used to fail to send the message because the socket
658 wasn't in the right state for the message to get through).
660 - Most transfer errors that occur during a daemon transfer are now
661 returned to the user in addition to being logged (some messages are
662 intended to be daemon-only and are not affected by this).
664 - Fixed a bug in the daemon authentication code when using one of the
665 batch-processing options.
667 - We try to work around some buggy IPv6 implementations that fail to
668 implement IPV6_V6ONLY. This should fix the "address in use" error
669 that some daemons get when running on an OS with a buggy IPv6
670 implementation. Also, if the new code gets this error, we might
671 suggest that the user specify --ipv4 or --ipv6 (if we think it will
674 - When the remote rsync dies, make a better effort to recover any error
675 messages it may have sent before dying (the local rsync used to just
676 die with a socket-write error).
678 - When using --delete and a --backup-dir that contains files that are
679 hard-linked to their destination equivalents, rsync now makes sure
680 that removed files really get removed (avoids a really weird rename()
683 - Avoid a bogus run-time complaint about a lack of 64-bit integers when
684 the int64 type is defined as an off_t and it actually has 64-bits.
686 - Added a configure check for open64() without mkstemp64() so that we
687 can avoid using mkstemp() when such a combination is encountered.
688 This bypasses a problem writing out large temp files on OSes such as
691 - Fixed an age-old crash problem with --read-batch on a local copy
692 (rsync was improperly assuming --whole-file for the local copy).
694 - When --dry-run (-n) is used and the destination directory does not
695 exist, rsync now produces a correct report of files that would be
696 sent instead of dying with a chdir() error.
698 - Fixed a bug that could cause a slow-to-connect rsync daemon to die
699 with an error instead of waiting for the connection to finish.
701 - Fixed an ssh interaction that could cause output to be lost when the
702 user chose to combine the output of rsync's stdout and stderr (e.g.
707 - Added the --partial-dir=DIR option that lets you specify where to
708 (temporarily) put a partially transferred file (instead of over-
709 writing the destination file). E.g. --partial-dir=.rsync-partial
710 Also added support for the RSYNC_PARTIAL_DIR environment variable
711 that, when found, transforms a regular --partial option (such as
712 the convenient -P option) into one that also specifies a directory.
714 - Added --keep-dirlinks (-K), which allows you to symlink a directory
715 onto another partition on the receiving side and have rsync treat it
716 as matching a normal directory from the sender.
718 - Added the --inplace option that tells rsync to write each destination
719 file without using a temporary file. The matching of existing data
720 in the destination file can be severely limited by this, but there
721 are also cases where this is more efficient (such as appending data).
722 Use only when needed (see the man page for more details).
724 - Added the "write only" option for the daemon's config file.
726 - Added long-option names for -4 and -6 (namely --ipv4 and --ipv6)
727 and documented all these options in the man page.
729 - Improved the handling of the --bwlimit option so that it's less
730 bursty, more accurate, and works properly over a larger range of
733 - The rsync daemon-over-ssh code now looks for SSH_CONNECTION and
734 SSH2_CLIENT in addition to SSH_CLIENT to figure out the IP address.
736 - Added the --checksum-seed=N option for advanced users.
738 - Batch writing/reading has a brand-new implementation that is simpler,
739 fixes a few weird problems with the old code (such as no longer
740 sprinkling the batch files into different dirs or even onto different
741 systems), and is much less intrusive into the code (making it easier
742 to maintain for the future). The new code generates just one data
743 file instead of three, which makes it possible to read the batch on
744 stdin via a remote shell. Also, the old requirement of forcing the
745 same fixed checksum-seed for all batch processing has been removed.
747 - If an rsync daemon has a module set with "list = no" (which hides its
748 presence in the list of available modules), a user that fails to
749 authenticate gets the same "unknown module" error that they would get
750 if the module were actually unknown (while still logging the real
751 error to the daemon's log file). This prevents fishing for module
754 - The daemon's "refuse options" config item now allows you to match
755 option names using wildcards and/or the single-letter option names.
757 - Each transferred file now gets its permissions and modified-time
758 updated before the temp-file gets moved into place. Previously, the
759 finished file would have a very brief window where its permissions
760 disallowed all group and world access.
762 - Added the ability to parse a literal IPv6 address in an "rsync:" URL
763 (e.g. rsync://[2001:638:500:101::21]:873/module/dir).
765 - The daemon's wildcard expanding code can now handle more than 1000
766 filenames (it's now limited by memory instead of having a hard-wired
771 - Some cleanup in the exclude code has saved some per-exclude memory
772 and made the code easier to maintain.
774 - Improved the argv-overflow checking for a remote command that has a
777 - Use rsyserr() in the various places that were still calling rprintf()
778 with strerror() as an arg.
780 - If an rsync daemon is listening on multiple sockets (to handle both
781 IPv4 and IPv6 to a single port), we now close all the unneeded file
782 handles after we accept a connection (we used to close just one of
785 - Optimized the handling of larger block sizes (rsync used to slow to a
786 crawl if the block size got too large).
788 - Optimized away a loop in hash_search().
790 - Some improvements to the sanitize_path() and clean_fname() functions
791 makes them more efficient and produce better results (while still
792 being compatible with the file-name cleaning that gets done on both
793 sides when sending the file-list).
795 - Got rid of alloc_sanitize_path() after adding a destination-buffer
796 arg to sanitize_path() made it possible to put all the former's
797 functionality into the latter.
799 - The file-list that is output when at least 4 verbose options are
800 specified reports the uid value on the sender even when rsync is
801 not running as root (since we might be sending to a root receiver).
805 - Added a "gen" target to rebuild most of the generated files,
806 including configure, config.h.in, the man pages, and proto.h.
808 - If "make proto" doesn't find some changes in the prototypes, the
809 proto.h file is left untouched (its time-stamp used to always be
812 - The variable $STRIP (that is optionally set by the install-strip
813 target's rule) was changed to $INSTALL_STRIP because some systems
814 have $STRIP already set in the environment.
816 - Fixed a build problem when SUPPORT_HARD_LINKS isn't defined.
818 - When cross-compiling, the gettimeofday() function is now assumed to
819 be a modern version that takes two-args (since we can't test it).
823 - The scripts in the testsuite dir were cleaned up a bit and a few
826 - Some new diffs were added to the patches dir, and some accepted
830 NEWS for rsync 2.6.2 (30 Apr 2004)
831 Protocol: 28 (unchanged)
836 - Fixed a major bug in the sorting of the filenames when --relative
837 is used for some sources (just sources such as "/" and "/*" were
838 affected). This fix ensures that we ask for the right file-list
839 item when requesting changes from the sender.
841 - Rsync now checks the return value of the close() function to
842 better report disk-full problems on an NFS file system.
844 - Restored the old daemon-server behavior of logging error messages
845 rather than returning them to the user. (A better long-term fix
846 will be sought in the future.)
848 - An obscure uninitialized-variable bug was fixed in the uid/gid
849 code. (This bug probably had no ill effects.)
853 - Got rid of the configure check for sys/sysctl.h (it wasn't used
854 and was causing a problem on some systems). Also improved the
855 broken-largefile-locking test to try to avoid failure due to an
858 - Fixed a compile problem on systems that don't define
861 - Fixed a compile problem in the popt source for compilers that
862 don't support __attribute__.
866 - Improved the testsuite's "merge" test to work on OSF1.
868 - Two new diffs were added to the patches dir.
871 NEWS for rsync 2.6.1 (26 Apr 2004)
872 Protocol: 28 (changed)
877 - Paths sent to an rsync daemon are more thoroughly sanitized when
878 chroot is not used. If you're running a non-read-only rsync
879 daemon with chroot disabled, *please upgrade*, ESPECIALLY if the
880 user privs you run rsync under is anything above "nobody".
884 - Lower memory use, more optimal transfer of data over the socket,
885 and lower CPU usage (see the INTERNAL section for details).
887 - The RSYNC_PROXY environment variable can now contain a
888 "USER:PASS@" prefix before the "HOST:PORT" information.
891 - The --progress output now mentions how far along in the transfer
892 we are, including both a count of files transferred and a
893 percentage of the total file-count that we've processed. It also
894 shows better current-rate-of-transfer and remaining-transfer-time
897 - Documentation changes now attempt to describe some often mis-
898 understood features more clearly.
902 - When -x (--one-file-system) is combined with -L (--copy-links) or
903 --copy-unsafe-links, no symlinked files are skipped, even if the
904 referent file is on a different filesystem.
906 - The --link-dest code now works properly for a non-root user when
907 (1) the UIDs of the source and destination differ and -o was
908 specified, or (2) when the group of the source can't be used on
909 the destination and -g was specified.
911 - Fixed a bug in the handling of -H (hard-links) that might cause
912 the expanded PATH/NAME value of the current item to get
913 overwritten (due to an expanded-name caching bug).
915 - We now reset the "new data has been sent" flag at the start of
916 each file we send. This makes sure that an interrupted transfer
917 with the --partial option set doesn't keep a shorter temp file
918 than the current basis file when no new data has been transfered
919 over the wire for that file.
921 - Fixed a byte-order problem in --batch-mode on big-endian machines.
924 - When using --cvs-exclude, the exclude items we get from a
925 per-directory's .cvsignore file once again only affect that one
926 directory (not all following directories too). The items are also
927 now properly word-split and parsed without any +/- prefix parsing.
929 - When specifying the USER@HOST: prefix for a file, the USER part
930 can now contain an '@', if needed (i.e. the last '@' is used to
931 find the HOST, not the first).
933 - Fixed some bugs in the handling of group IDs for non-root users:
934 (1) It properly handles a group that the sender didn't have a name
935 for (it would previously skip changing the group on any files in
936 that group). (2) If --numeric-ids is used, rsync no longer
937 attempts to set groups that the user doesn't have the permission
940 - Fixed the "refuse options" setting in the rsyncd.conf file.
942 - Improved the -x (--one-file-system) flag's handling of any mount-
943 point directories we encounter. It is both more optimal (in that
944 it no longer does a useless scan of the contents of the mount-
945 point dirs) and also fixes a bug where a remapped mount of the
946 original filesystem could get discovered in a subdir we should be
949 - Rsync no longer discards a double-slash at the start of a filename
950 when trying to open the file. It also no longer constructs names
951 that start with a double slash (unless the user supplied them).
953 - Path-specifying options to a daemon should now work the same with
954 or without chroot turned on. Previously, such a option (such as
955 --link-dest) would get its absolute path munged into a relative
956 one if chroot was not on, making that setting fairly useless.
957 Rsync now transforms the path into one that is based on the
958 module's base dir when chroot is not enabled.
960 - Fixed a compatibility problem interacting with older rsync
961 versions that might send us an empty --suffix value without
962 telling us that --backup-dir was specified.
964 - The "hosts allow" option for a daemon-over-remote-shell process
965 now has improved support for IPv6 addresses and a fix for systems
966 that have a length field in their socket structs.
968 - Fixed the ability to request an empty backup --suffix when sending
969 files to an rsync daemon.
973 - Most of the I/O is now buffered, which results in a pretty large
974 speedup when running under MS Windows. (Craig Barratt)
976 - Optimizations to the name-handling/comparing code have made some
977 significant reductions in user-CPU time for large file sets.
979 - Some cleanup of the variable types make the code more consistent.
981 - Reduced memory requirements of hard link preservation.
984 - Implemented a new algorithm for hard-link handling that speeds up
985 the code significantly. (J.W. Schultz and Wayne Davison)
987 - The --hard-link option now uses the first existing file in the
988 group of linked files as the basis for the transfer. This
989 prevents the sub-optimal transfer of a file's data when a new
990 hardlink is added on the sending side and it sorts alphabetically
991 earlier in the list than the files that are already present on the
994 - Dropped support for protocol versions less than 20 (2.3.0 released
995 15 Mar 1999) and activated warnings for protocols less than 25
996 (2.5.0 released 23 Aug 2001). (Wayne Davison and J.W. Schultz,
999 - More optimal data transmission for --hard-links (protocol 28).
1001 - More optimal data transmission for --checksum (protocol 28).
1003 - Less memory is used when --checksum is specified.
1005 - Less memory is used in the file list (a per-file savings).
1007 - The generator is now better about not modifying the file list
1008 during the transfer in order to avoid a copy-on-write memory
1009 bifurcation (on systems where fork() uses shared memory).
1010 Previously, rsync's shared memory would slowly become unshared,
1011 resulting in real memory usage nearly doubling on the receiving
1012 side by the end of the transfer. Now, as long as permissions
1013 are being preserved, the shared memory should remain that way
1014 for the entire transfer.
1016 - Changed hardlink info and file_struct + strings to use allocation
1017 pools. This reduces memory use for large file-sets and permits
1018 freeing memory to the OS. (J.W. Schultz)
1020 - The 2 pipes used between the receiver and generator processes
1021 (which are forked on the same machine) were reduced to 1 pipe and
1022 the protocol improved so that (1) it is now impossible to have the
1023 "redo" pipe fill up and hang rsync, and (2) trailing messages from
1024 the receiver don't get lost on their way through the generator
1025 over to the sender (which mainly affected hard-link messages and
1026 verbose --stats output).
1028 - Improved the internal uid/gid code to be more portable and a
1029 little more optimized.
1031 - The device numbers sent when using --devices are now sent as
1032 separate major/minor values with 32-bit accuracy (protocol 28).
1033 Previously, the copied devices were sent as a single 32-bit
1034 number. This will make inter-operation of 64-bit binaries more
1035 compatible with their 32-bit brethren (with both ends of the
1036 connection are using protocol 28). Note that optimizations in the
1037 binary protocol for sending the device numbers often results in
1038 fewer bytes being used than before, even though more precision is
1041 - Some cleanup of the exclude/include structures and its code made
1042 things clearer (internally), simpler, and more efficient.
1044 - The reading & writing of the file-list in batch-mode is now
1045 handled by the same code that sends & receives the list over the
1046 wire. This makes it much easier to maintain. (Note that the
1047 batch code is still considered to be experimental.)
1051 - The configure script now accepts --with-rsyncd-conf=PATH to
1052 override the default value of the /etc/rsyncd.conf file.
1054 - Fixed configure bug when running "./configure --disable-ipv6".
1056 - Fixed compilation problem on Tru64 Unix (having to do with
1057 sockaddr.sa_len and sockaddr.sin_len).
1061 - Fixed "make test" bug when build dir is not the source dir.
1063 - Added a couple extra diffs in the "patches" dir, removed the ones
1064 that got applied, and rebuilt the rest.
1067 NEWS for rsync 2.6.0 (1 Jan 2004)
1068 Protocol: 27 (changed)
1069 Changes since 2.5.7:
1073 * "ssh" is now the default remote shell for rsync. If you want to
1074 change this, configure like this: "./configure --with-rsh=rsh".
1076 * Added --files-from, --no-relative, --no-implied-dirs, and --from0.
1077 Note that --from0 affects the line-ending character for all the
1078 files read by the --*-from options. (Wayne Davison)
1080 * Length of csum2 is now per-file starting with protocol version
1083 * Per-file dynamic block size is now sqrt(file length). The
1084 per-file checksum size is determined according to an algorithm
1085 provided by Donovan Baarda which reduces the probability of rsync
1086 algorithm corrupting data and falling back using the whole md4
1087 checksums. (J.W. Schultz, Donovan Baarda)
1089 * The --stats option no longer includes the (debug) malloc summary
1090 unless the verbose option was specified at least twice.
1092 * Added a new error/warning code for when files vanish from the
1093 sending side. Made vanished source files not interfere with the
1094 file-deletion pass when --delete-after was specified.
1096 * Various trailing-info sections are now preceded by a newline.
1100 * Fixed several exclude/include matching bugs when using wild-cards.
1101 This has a several user-visible effects, all of which make the
1102 matching more consistent and intuitive. This should hopefully not
1103 cause anyone problems since it makes the matching work more like
1104 what people are expecting. (Wayne Davison)
1106 - A pattern with a "**" no longer causes a "*" to match slashes.
1107 For example, with "/*/foo/**", "foo" must be 2 levels deep.
1108 [If your string has BOTH "*" and "**" wildcards, changing the
1109 "*" wildcards to "**" will provide the old behavior in all
1112 - "**/foo" now matches at the base of the transfer (like /foo
1113 does). [Use "/**/foo" to get the old behavior in all versions.]
1115 - A non-anchored wildcard term floats to match beyond the base of
1116 the transfer. E.g. "CVS/R*" matches at the end of the path,
1117 just like the non-wildcard term "CVS/Root" does. [Use "/CVS/R*"
1118 to get the old behavior in all versions.]
1120 - Including a "**" in the match term causes it to be matched
1121 against the entire path, not just the name portion, even if
1122 there aren't any interior slashes in the term. E.g. "foo**bar"
1123 would exclude "/path/foo-bar" (just like before) as well as
1124 "/foo-path/baz-bar" (unlike before). [Use "foo*bar" to get the
1125 old behavior in all versions.]
1127 * The exclude list specified in the daemon's config file is now
1128 properly applied to the pulled items no matter how deep the
1129 user's file-args are in the source tree. (Wayne Davison)
1131 * For protocol version >= 27, mdfour_tail() is called when the
1132 block size (including checksum_seed) is a multiple of 64.
1133 Previously it was not called, giving the wrong MD4 checksum.
1136 * For protocol version >= 27, a 64 bit bit counter is used in
1137 mdfour.c as required by the RFC. Previously only a 32 bit bit
1138 counter was used, causing incorrect MD4 file checksums for
1139 file sizes >= 512MB - 4. (Craig Barratt)
1141 * Fixed a crash bug when interacting with older rsync versions and
1142 multiple files of the same name are destined for the same dir.
1145 * Keep tmp names from overflowing MAXPATHLEN.
1147 * Make --link-dest honor the absence of -p, -o, and -g.
1149 * Made rsync treat a trailing slash in the destination in a more
1152 * Fixed file I/O error detection. (John Van Essen)
1154 * Fixed bogus "malformed address {hostname}" message in rsyncd log
1155 when checking IP address against hostnames from "hosts allow"
1156 and "hosts deny" parameters in config file.
1158 * Print heap statistics when verbose >= 2 instead of when >= 1.
1160 * Fixed a compression (-z) bug when syncing a mostly-matching file
1161 that contains already-compressed data. (Yasuoka Masahiko and
1164 * Fixed a bug in the --backup code that could cause deleted files
1165 to not get backed up.
1167 * When the backup code makes new directories, create them with mode
1168 0700 instead of 0755 (since the directory permissions in the
1169 backup tree are not yet copied from the main tree).
1171 * Call setgroups() in a more portable manner.
1173 * Improved file-related error messages to better indicate exactly
1174 what pathname failed. (Wayne Davison)
1176 * Fixed some bugs in the handling of --delete and --exclude when
1177 using the --relative (-R) option. (Wayne Davison)
1179 * Fixed bug that prevented regular files from replacing
1180 special files and caused a directory in --link-dest or
1181 --compare-dest to block the creation of a file with the
1182 same path. A directory still cannot be replaced by a
1183 regular file unless --delete specified. (J.W. Schultz)
1185 * Detect and report when open or opendir succeed but read and
1186 readdir fail caused by network filesystem issues and truncated
1187 files. (David Norwood, Michael Brown, J.W. Schultz)
1189 * Added a fix that should give ssh time to restore the tty settings
1190 if the user presses Ctrl-C at an ssh password prompt.
1194 * Eliminated vestigial support for old versions that we stopped
1195 supporting. (J.W. Schultz)
1197 * Simplified some of the option-parsing code. (Wayne Davison)
1199 * Some cleanup made to the exclude code, as well as some new
1200 defines added to enhance readability. (Wayne Davison)
1202 * Changed the protocol-version code so that it can interact at a
1203 lower protocol level than the maximum supported by both sides.
1204 Added an undocumented option, --protocol=N, to force the value
1205 we advertise to the other side (primarily for testing purposes).

1220 Protocol: 26 (unchanged)
1221 Changes since 2.5.5:
1225 * The --delete-after option now implies --delete. (Wayne Davison)
1227 * The --suffix option can now be used with --backup-dir. (Michael
1230 * Combining "::" syntax with the -rsh/-e option now uses the
1231 specified remote-shell as a transport to talk to a (newly-spawned)
1232 server-daemon. This allows someone to use daemon features, such
1233 as modules, over a secure protocol, such as ssh. (JD Paul)
1235 * The rsync:// syntax for daemon connections is now accepted in the
1238 * If the file name given to --include-from or --exclude-from is "-",
1239 rsync will read from standard input. (J.W. Schultz)
1241 * New option --link-dest which is like --compare-dest except that
1242 unchanged files are hard-linked in to the destination directory.
1245 * Don't report an error if an excluded file disappears during an
1246 rsync run. (Eugene Chupriyanov and Bo Kersey)
1248 * Added .svn to --cvs-exclude list to support subversion. (Jon
1251 * Properly support IPv6 addresses in the rsyncd.conf "hosts allow"
1252 and "hosts deny" fields. (Hideaki Yoshifuji)
1254 * Changed exclude file handling to permit DOS or MAC style line
1255 terminations. (J.W. Schultz)
1257 * Ignore errors from chmod when -p/-a/--preserve-perms is not set.
1262 * Fix "forward name lookup failed" errors on AIX 4.3.3. (John
1263 L. Allen, Martin Pool)
1265 * Generate each file's rolling-checksum data as we send it, not
1266 in a separate (memory-eating) pass before hand. This prevents
1267 timeout errors on really large files. (Stefan Nehlsen)
1269 * Fix compilation on Tru64. (Albert Chin, Zoong Pham)
1271 * Better handling of some client-server errors. (Martin Pool)
1273 * Fixed a crash that would occur when sending a list of files that
1274 contains a duplicate name (if it sorts to the end of the file
1275 list) and using --delete. (Wayne Davison)
1277 * Fixed the file-name duplicate-removal code when dealing with multiple
1278 dups in a row. (Wayne Davison)
1280 * Fixed a bug that caused rsync to lose the exit status of its child
1281 processes and sometimes return an exit code of 0 instead of showing
1282 an error. (David R. Staples, Dave Dykstra)
1284 * Fixed bug in --copy-unsafe-links that caused it to be completely
1285 broken. (Dave Dykstra)
1287 * Prevent infinite recursion in cleanup code under certain circumstances.
1288 (Sviatoslav Sviridov and Marc Espie)
1290 * Fixed a bug that prevented rsync from creating intervening directories
1291 when --relative-paths/-R is set. (Craig Barratt)
1293 * Prevent "Connection reset by peer" messages from Cygwin. (Randy O'Meara)
1297 * Many code cleanups and improved internal documentation. (Martin
1300 * Portability fixes. (Dave Dykstra and Wayne Davison)
1302 * More test cases. (Martin Pool)
1304 * Some test-case fixes. (Brian Poole, Wayne Davison)
1306 * Updated included popt to the latest vendor drop, version 1.6.4.
1309 * Updated config.guess and config.sub to latest versions; this
1310 means rsync should build on more platforms. (Paul Green)
1313 NEWS for rsync 2.5.5, aka Snowy River (2 Apr 2002)
1314 Protocol: 26 (unchanged)
1315 Changes since 2.5.4:
1319 * With --progress, when a transfer is complete show the time taken;
1320 otherwise show expected time to complete. (Cameron Simpson)
1322 * Make "make install-strip" works properly, and "make install"
1323 accepts a DESTDIR variable for help in building binary packages.
1324 (Peter Breitenlohner, Greg Louis)
1326 * If configured with --enable-maintainer-mode, then on receipt of
1327 a fatal signal rsync will try to open an xterm running gdb,
1328 similarly to Samba's "panic action" or GNOME's bug-buddy.
1334 * Fix situation where failure to fork (e.g. because out of process
1335 slots) would cause rsync to kill all processes owned by the
1336 current user. Yes, really! (Paul Haas, Martin Pool)
1338 * Fix test suite on Solaris. (Jos Backus, Martin Pool)
1340 * Fix minor memory leak in socket code. (Dave Dykstra, Martin
1343 * Fix --whole-file problem that caused it to be the default even
1344 for remote connections. (Martin Pool, Frank Schulz)
1346 * Work around bug in Mac OS X mkdir(2), which cannot handle
1348 <http://www.opensource.apple.com/bugs/X/BSD%20Kernel/2734739.html>
1351 * Improved network error handling. (Greg A. Woods)

1360 * Additional fix for zlib double-free bug. (Martin Pool, Andrew
1361 Tridgell) (CVE CAN-2002-0059)
1365 * Merge in changes from zlib 1.1.3 to zlib 1.1.4. (Jos Backus)
1366 (Note that rsync still uses a custom version of zlib; you can
1367 not just link against a system library. See zlib/README.rsync)

1373 Protocol: 26 (unchanged)
1374 Changes since 2.5.2:
1378 * Make sure that supplementary groups are removed from a server
1379 process after changing uid and gid. (Ethan Benson) (Debian bug
1380 #132272, CVE CAN-2002-0080)
1384 * Fix zlib double-free bug. (Owen Taylor, Mark J Cox) (CVE
1387 * Fixed problem that in many cases caused the error message
1388 unexpected read size of 0 in map_ptr
1389 and resulted in the wrong data being copied.
1391 * Fixed compilation errors on some systems caused by the use of
1392 "unsigned int64" in rsync.h.
1394 * Fixed problem on systems such as Sunos4 that do not support realloc
1395 on a NULL pointer; error was "out of memory in flist_expand".
1397 * Fix for rsync server processes hanging around after the client
1398 unexpectedly disconnects. (Colin Walters) (Debian bug #128632)
1400 * Cope with BSD systems on which mkdir() will not accept a trailing
1405 * Merge in changes from zlib 1.1.2 to zlib 1.1.3. (Note that
1406 rsync still uses a custom version of zlib; you can not just link
1407 against a system library. See zlib/README.rsync)
1409 * Command to initiate connections is only shown with -vv, rather
1410 than -v as in 2.5.2. Output from plain -v is more similar to
1411 what was historically used so as not to break scripts that try
1412 to parse the output.
1414 * Added --no-whole-file and --no-blocking-io options (Dave Dykstra)
1416 * Made the --write-batch and --read-batch options actually work
1417 and added documentation in the man page (Jos Backus)
1419 * If the daemon is unable to fork a child to accept a connection,
1420 print an error message. (Colin Walters)
1423 NEWS for rsync 2.5.2 (26 Jan 2002)
1424 Protocol: 26 (changed)
1425 Changes since 2.5.1:
1429 * Signedness security patch from Sebastian Krahmer
1430 <krahmer@suse.de> -- in some cases we were not sufficiently
1431 careful about reading integers from the network.
1435 * Fix possible string mangling in log files.
1437 * Fix for setting local address of outgoing sockets.
1439 * Better handling of hardlinks and devices on platforms with
1440 64-bit dev_t or ino_t.
1442 * Name resolution on machines supporting IPv6 is improved.
1444 * Fix for device nodes. (dann frazier) (Debian #129135)
1448 * With -v, rsync now shows the command used to initiate an ssh/rsh
1451 * --statistics now shows memory heap usage on platforms that
1454 * "The Ted T'so school of program optimization": make progress
1455 visible and people will think it's faster. (With --progress,
1456 rsync will show you how many files it has seen as it builds the
1457 file_list, giving some indication that it has not hung.)
1459 * Improvements to batch mode support. This is still experimental
1460 but testing would be welcome. (Jos Backus)
1462 * New --ignore-existing option, patch previously distributed with
1463 Vipul's Razor. (Debian #124286)

1475 * Correct string<->address parsing for both IPv4 and 6.
1476 (YOSHIFUJI Hideaki, SUMIKAWA Munechika and Jun-ichiro "itojun"
1479 * Various fixes for IPv6 support. (Dave Dykstra)
1481 * rsync.1 typo fix. (Matt Kraai)
1483 * Test suite typo fixes. (Tom Schmidt)
1485 * rsync.1 grammar and clarity improvements. (Edward
1488 * Correction to ./configure tests for inet_ntop. (Jeff Garzik)
1492 * --progress and -P now show estimated data transfer rate (in a
1493 multiple of bytes/s) and estimated time to completion. (Rik
1496 * --no-detach option, required to run as a W32 service and also
1497 useful when running on Unix under daemontools, AIX's SRC, or a
1498 debugger. (Max Bowsher, Jos Backus)
1500 * Clearer error messages for some conditions.
1503 NEWS for rsync 2.5.0 (30 Nov 2001)
1504 Protocol: 25 (changed)
1505 Changes since 2.4.6:
1509 * Martin Pool <mbp@samba.org> is now a co-maintainer.
1513 * Support for LSB-compliant packaging <http://www.linuxbase.org/>
1515 * Shell wildcards are allowed in "auth users" lines.
1517 * Merged UNC rsync+ patch to support creation of standalone patch
1518 sets. By Bert J. Dempsey and Debra Weiss, updated by Jos
1519 Backus. <http://www.ils.unc.edu/i2dsi/unc_rsync+.html>
1521 * IPv6 support based on a patch from KAME.net, on systems
1522 including modern versions of Linux, Solaris, and HP-UX. Also
1523 includes IPv6 compatibility functions for old OSs by the
1524 Internet Software Consortium, Paul Vixie, the OpenSSH
1525 portability project, and OpenBSD.
1529 * Include/exclude cluestick: with -vv, print out whether files are
1530 included or excluded and why.
1532 * Many error messages have more friendly explanations and more
1535 * Manual page improvements plus scanty protocol documentation.
1537 * When running as --daemon in the background and using a "log
1538 file" rsyncd.conf directive, close the log file every time it is
1539 open when going to sleep on the socket. This allows the log
1540 file to get cleaned out by another process.
1542 * Change to using libpopt rather than getopt for processing
1543 options. This makes the code cleaner and the behaviour more
1544 consistent across platforms. popt is included and built if not
1545 installed on the platform.
1547 * More details in --version, including note about whether 64-bit
1548 files, symlinks and hardlinks are supported.
1550 * MD4 code may use less CPU cycles.
1552 * Use mkstemp on systems where it is secure. If we use mktemp,
1553 explain that we do it in a secure way.
1555 * --whole-file is the default when source and target are on the
1560 * Fix for various bugs causing rsync to hang.
1562 * Attempt to fix Large File Summit support on AIX.
1564 * Attempt to fix error handling lockup bug.
1566 * Give a non-0 exit code if *any* of the files we have been asked
1567 to transfer fail to transfer.
1569 * For log messages containing ridiculously long strings that might
1570 overflow a buffer rsync no longer aborts, but rather prints an
1571 ellipsis at the end of the string. (Patch from Ed Santiago.)
1575 * Improved support for UNICOS (tested on Cray T3E and Cray SV1)
1577 * autoconf2.52 (or later) is now required to rebuild the autoconf
1578 scripts. It is not required to simply build rsync.
