1.1 misho 1: NEWS for rsync 3.0.8 (26 Mar 2011)
2: Protocol: 30 (unchanged)
3: Changes since 3.0.7:
4:
5: BUG FIXES:
6:
7: - Fixed two buffer-overflow issues: one where a directory path that is
8: exactly MAXPATHLEN was not handled correctly, and one handling a
9: --backup-dir that is extra extra large.
10:
11: - Fixed a data-corruption issue when preserving hard-links without
12: preserving file ownership, and doing deletions either before or during
13: the transfer (CVE-2011-1097). This fixes some assert errors in the
14: hard-linking code, and some potential failed checksums (via -c) that
15: should have matched.
16:
17: - Fixed a potential crash when an rsync daemon has a filter/exclude list
18: and the transfer is using ACLs or xattrs.
19:
20: - Fixed a hang if a really large file is being processed by an rsync that
21: can't handle 64-bit numbers. Rsync will now complain about the file
22: being too big and skip it.
23:
24: - For devices and special files, we now avoid gathering useless ACL and/or
25: xattr information for files that aren't being copied. (The un-copied
26: files are still put into the file list, but there's no need to gather
27: data that is not going to be used.) This ensures that if the user uses
28: --no-D, that rsync can't possibly complain about being unable to gather
29: extended information from special files that are in the file list (but
30: not in the transfer).
31:
32: - Properly handle requesting remote filenames that start with a dash. This
33: avoids a potential error where a filename could be interpreted as a
34: (usually invalid) option.
35:
36: - Fixed a bug in the comparing of upper-case letters in file suffixes for
37: --skip-compress.
38:
39: - If an rsync daemon has a module configured without a path setting, rsync
40: will now disallow access to that module.
41:
42: - If the destination arg is an empty string, it will be treated as a
43: reference to the current directory (as 2.x used to do).
44:
45: - If rsync was compiled with a newer time-setting function (such as
46: lutimes), rsync will fall-back to an older function (such as utimes) on a
47: system where the newer function is not around. This helps to make the
48: rsync binary more portable in mixed-OS-release situations.
49:
50: - Fixed a batch-file writing bug that would not write out the full set of
51: compatibility flags that the transfer was using. This fixes a potential
52: protocol problem for a batch file that contains a sender-side I/O error:
53: it would have been sent in a way that the batch-reader wasn't expecting.
54:
55: - Some improvements to the hard-linking code to ensure that device-number
56: hashing is working right, and to supply more information if the hard-link
57: code fails.
58:
59: - The --inplace code was improved to not search for an impossible checksum
60: position. The quadruple-verbose chunk[N] message will now mention when
61: an inplace chunk was handled by a seek rather than a read+write.
62:
63: - Improved ACL mask handling, e.g. for Solaris.
64:
65: - Fixed a bug that prevented --numeric-ids from disabling the translation
66: of user/group IDs for ACLs.
67:
68: - Fixed an issue where an xattr and/or ACL transfer that used an alt-dest
69: option (e.g. --link-dest) could output an error trying to itemize the
70: changes against the alt-dest directory's xattr/ACL info but was instead
71: trying to access the not-yet-existing new destination directory.
72:
73: - Improved xattr system-error messages to mention the full path to the
74: file.
75:
76: - The --link-dest checking for identical symlinks now avoids considering
77: attribute differences that cannot be changed on the receiver.
78:
79: - Avoid trying to read/write xattrs on certain file types for certain OSes.
80: Improved configure to set NO_SYMLINK_XATTRS, NO_DEVICE_XATTRS, and/or
81: NO_SPECIAL_XATTRS defines in config.h.
82:
83: - Improved the unsafe-symlink errors messages.
84:
85: - Fixed a bug setting xattrs on new files that aren't user writable.
86:
87: - Avoid re-setting xattrs on a hard-linked file w/the same xattrs.
88:
89: - Fixed a bug with --fake-super when copying files and dirs that aren't
90: user writable.
91:
92: - Fixed a bug where a sparse file could have its last sparse block turned
93: into a real block when rsync sets the file size (requires ftruncate).
94:
95: - If a temp-file name is too long, rsync now avoids truncating the name in
96: the middle of adjacent high-bit characters. This prevents a potential
97: filename error if the filesystem doesn't allow a name to contain an
98: invalid multi-byte sequence.
99:
100: - If a muli-protocol socket connection fails (i.e., when contacting a
101: daemon), we now report all the failures, not just the last one. This
102: avoids losing a relevant error (e.g. an IPv4 connection-refused error)
103: that happened before the final error (e.g. an IPv6 protocol-not-supported
104: error).
105:
106: - Generate a transfer error if we try to call chown with a -1 for a uid or
107: a gid (which is not settable).
108:
109: - Fixed the working of --force when used with --one-file-system.
110:
111: - Fix the popt arg parsing so that an option that doesn't take an arg will
112: reject an attempt to supply one (can configure --with-included-popt if
113: your system's popt library doesn't yet have this fix).
114:
115: - A couple minor option tweaks to the support/rrsync script, and also some
116: regex changes that make vim highlighting happier.
117:
118: - Fixed some issues in the support/mnt-excl script.
119:
120: - Various manpage improvements.
121:
122: ENHANCEMENTS:
123:
124: - Added ".hg/" to the default cvs excludes (see -C & --cvs-exclude).
125:
126: DEVELOPER RELATED:
127:
128: - Use lchmod() whenever it is available (not just on symlinks).
129:
130: - A couple fixes to the socketpair_tcp() routine.
131:
132: - Updated the helper scripts in the packaging subdirectory.
133:
134: - Renamed configure.in to configure.ac.
135:
136: - Fixed configure's checking for iconv routines for newer OS X versions.
137:
138: - Fixed the testsuite/xattrs.test script on OS X.
139:
140:
141: NEWS for rsync 3.0.7 (31 Dec 2009)
142: Protocol: 30 (unchanged)
143: Changes since 3.0.6:
144:
145: BUG FIXES:
146:
147: - Fixed a bogus free when using --xattrs with --backup.
148:
149: - Avoid an error when --dry-run was trying to stat a prior hard-link file
150: that hasn't really been created.
151:
152: - Fixed a problem with --compress (-z) where the receiving side could
153: return the error "inflate (token) returned -5".
154:
155: - Fixed a bug where --delete-during could delete in a directory before it
156: noticed that the sending side sent an I/O error for that directory (both
157: sides of the transfer must be at least 3.0.7).
158:
159: - Improved --skip-compress's error handling of bad character-sets and got
160: rid of a lingering debug fprintf().
161:
162: - Fixed the daemon's conveyance of io_error value from the sender.
163:
164: - An rsync daemon use seteuid() (when available) if it used setuid().
165:
166: - Get the permissions right on a --fake-super transferred directory that
167: needs more owner permissions to emulate root behavior.
168:
169: - An absolute-path filter rule (i.e. with a '/' modifier) no longer loses
170: its modifier when sending the filter rules to the remote rsync.
171:
172: - Improved the "--delete does not work without -r or -d" message.
173:
174: - Improved rsync's handling of --timeout to avoid a weird timeout case
175: where the sender could timeout even though it has recently written data
176: to the socket (but hasn't read data recently, due to the writing).
177:
178: - Some misc manpage improvements.
179:
180: - Fixed the chmod-temp-dir testsuite on a system without /var/tmp.
181:
182: - Make sure that a timeout specified in the daemon's config is used as a
183: maximum timeout value when the user also specifies a timeout.
184:
185: - Improved the error-exit reporting when rsync gets an error trying to
186: cleanup after an error: the initial error is reported.
187:
188: - Improved configure's detection of IPv6 for solaris and cygwin.
189:
190: - The AIX sysacls routines will now return ENOSYS if ENOTSUP is missing.
191:
192: - Made our (only used if missing) getaddrinfo() routine use inet_pton()
193: (which we also provide) instead of inet_aton().
194:
195: - The exit-related debug messages now mention the program's role so it is
196: clear who output what message.
197:
198: DEVELOPER RELATED:
199:
200: - Got rid of type-punned compiler warnings output by newer gcc versions.
201:
202: - The Makefile now ensures that proto.h will be rebuilt if config.h changes.
203:
204: - The testsuite no longer uses "id -u", so it works better on solaris.
205:
206:
207: NEWS for rsync 3.0.6 (8 May 2009)
208: Protocol: 30 (unchanged)
209: Changes since 3.0.5:
210:
211: BUG FIXES:
212:
213: - Fixed a --read-batch hang when rsync is reading a batch file that was
214: created from an incremental-recursion transfer.
215:
216: - Fixed the daemon's socket code to handle the simultaneous arrival of
217: multiple connections.
218:
219: - Fix --safe-links/--copy-unsafe-links to properly handle symlinks that
220: have consecutive slashes in the value.
221:
222: - Fixed the parsing of an [IPv6_LITERAL_ADDR] when a USER@ is prefixed.
223:
224: - The sender now skips a (bogus) symlink that has a 0-length value, which
225: avoids a transfer error in the receiver.
226:
227: - Fixed a case where the sender could die with a tag-0 error if there was
228: an I/O during the sending of the file list.
229:
230: - Fixed the rrsync script to avoid a server-side problem when -e is at the
231: start of the short options.
232:
233: - Fixed a problem where a vanished directory could turn into an exit code
234: 23 instead of the proper exit code 24.
235:
236: - Fixed the --iconv conversion of symlinks when doing a local copy.
237:
238: - Fixed a problem where --one-file-system was not stopping deletions on the
239: receiving side when a mount-point directory did not match a directory in
240: the transfer.
241:
242: - Fixed the dropping of an ACL mask when no named ACL values were present.
243:
244: - Fixed an ACL/xattr corruption issue where the --backup option could cause
245: rsync to associate the wrong ACL/xattr information with received files.
246:
247: - Fixed the use of --xattrs with --only-write-batch.
248:
249: - Fixed the use of --dry-run with --read-batch.
250:
251: - Fixed configure's erroneous use of target.
252:
253: - Fixed configure's --disable-debug option.
254:
255: - Fixed a run-time issue for systems that can't find iconv_open() by adding
256: the --disable-iconv-open configure option.
257:
258: - Complain and die if the user tries to combine --remove-source-files (or
259: the deprecated --remove-sent-files) with --read-batch.
260:
261: - Fixed an failure transferring special files from Solaris to Linux.
262:
263:
264: NEWS for rsync 3.0.5 (28 Dec 2008)
265: Protocol: 30 (unchanged)
266: Changes since 3.0.4:
267:
268: BUG FIXES:
269:
270: - Initialize xattr data in a couple spots in the hlink code, which avoids a
271: crash when the xattr pointer's memory happens to start out non-zero.
272: Also fixed the itemizing of an alt-dest file's xattrs when hard-linking.
273:
274: - Don't send a bogus "-" option to an older server if there were no short
275: options specified.
276:
277: - Fixed skipping of unneeded updates in a batch file when incremental
278: recursion is active. Added a test for this. Made batch-mode handle
279: "redo" files properly (and without hanging).
280:
281: - Fix the %P logfile escape when the daemon logs from inside a chroot.
282:
283: - Fixed the use of -s (--protect-args) when used with a remote source or
284: destination that had an empty path (e.g. "host:"). Also fixed a problem
285: when -s was used when accessing a daemon via a remote-shell.
286:
287: - Fixed the use of a dot-dir path (e.g. foo/./bar) inside a --files-from
288: file when the root of the transfer isn't the current directory.
289:
290: - Fixed a bug with "-K --delete" removing symlinks to directories when
291: incremental recursion is active.
292:
293: - Fixed a hard to trigger hang when using --remove-source-files.
294:
295: - Got rid of an annoying delay when accessing a daemon via a remote-shell.
296:
297: - Properly ignore (superfluous) source args on a --read-batch command.
298:
299: - Improved the manpage's description of the '*' wildcard to remove the
300: confusing "non-empty" qualifier.
301:
302: - Fixed reverse lookups in the compatibility-library version of
303: getnameinfo().
304:
305: - Fixed a bug when using --sparse on a sparse file that has over 2GB of
306: consecutive sparse data.
307:
308: - Avoid a hang when using at least 3 --verbose options on a transfer with a
309: client sender (which includes local copying).
310:
311: - Fixed a problem with --delete-delay reporting an error when it was ready
312: to remove a directory that was now gone.
313:
314: - Got rid of a bunch of "warn_unused_result" compiler warnings.
315:
316: - If an ftruncate() on a received file fails, it now causes a partial-
317: transfer warning.
318:
319: - Allow a path with a leading "//" to be preserved (CYGWIN only).
320:
321: ENHANCEMENTS:
322:
323: - Made the support/atomic-rsync script able to perform a fully atomic
324: update of the copied hierarchy when the destination is setup using a
325: particular symlink idiom.
326:
327:
328: NEWS for rsync 3.0.4 (6 Sep 2008)
329: Protocol: 30 (unchanged)
330: Changes since 3.0.3:
331:
332: BUG FIXES:
333:
334: - Fixed a bug in the hard-linking code where it would sometimes try to
335: allocate 0 bytes of memory (which fails on some OSes, such as AIX).
336:
337: - Fixed the hard-linking of files from a device that has a device number
338: of 0 (which seems to be a common device number on NetBSD).
339:
340: - Fixed the handling of a --partial-dir that cannot be created. This
341: particularly impacts the --delay-updates option (since the files cannot
342: be delayed without a partial-dir), and was potentially destructive if
343: the --remove-source-files was also specified.
344:
345: - Fixed a couple issues in the --fake-super handling of xattrs when the
346: destination files have root-level attributes (e.g. selinux values) that
347: a non-root copy can't affect.
348:
349: - Improved the keep-alive check in the generator to fire consistently in
350: incremental-recursion mode when --timeout is enabled.
351:
352: - The --iconv option now converts the content of a symlink too, instead
353: of leaving it in the wrong character-set (requires 3.0.4 on both sides
354: of the transfer).
355:
356: - When using --iconv, if a filename fails to convert on the receiving side,
357: this no longer makes deletions in the root-dir of the transfer fail
358: silently (the user now gets a warning about deletions being disabled
359: due to IO error as long as --ignore-errors was not specified).
360:
361: - When using --iconv, if a server-side receiver can't convert a filename,
362: the error message sent back to the client no longer mangles the name
363: with the wrong charset conversion.
364:
365: - Fixed a potential alignment issue in the IRIX ACL code when allocating
366: the initial "struct acl" object. Also, cast mallocs to avoid warnings.
367:
368: - Changed some errors that were going to stdout to go to stderr.
369:
370: - Made human_num() and human_dnum() able to output a negative number
371: (rather than outputting a cryptic string of punctuation).
372:
373: ENHANCEMENTS:
374:
375: - Rsync will avoid sending an -e option to the server if an older protocol
376: is requested (and thus the option would not be useful). This lets the
377: user specify the --protocol=29 option to access an overly-restrictive
378: server that is rejecting the protocol-30 use of -e to the server.
379:
380: - Improved the message output for an RERR_PARTIAL exit.
381:
382: DEVELOPER RELATED:
383:
384: - The Makefile will not halt for just a timestamp change on the Makefile
385: or the configure files, only for actual changes in content.
386:
387: - Changed some commands in the testsuite's xattrs.test that called "rsync"
388: instead of "$RSYNC".
389:
390: - Enhanced the release scripts to be able to handle a branch release and
391: to do even more consistency checks on the files.
392:
393:
394: NEWS for rsync 3.0.3 (29 Jun 2008)
395: Protocol: 30 (unchanged)
396: Changes since 3.0.2:
397:
398: BUG FIXES:
399:
400: - Fixed a wildcard matching problem in the daemon when a module has
401: "use chroot" enabled.
402:
403: - Fixed a crash bug in the hard-link code.
404:
405: - Fixed the sending of xattr directory information when the code finds a
406: --link-dest or --copy-dest directory with unchanged xattrs -- the
407: destination directory now gets these unchanged xattrs properly applied.
408:
409: - Fixed an xattr-sending glitch that could cause an "Internal abbrev"
410: error.
411:
412: - Fixed the combination of --xattrs and --backup.
413:
414: - The generator no longer allows a '.' dir to be excluded by a daemon-
415: exclude rule.
416:
417: - Fixed deletion handling when copying a single, empty directory (with no
418: files) to a differently named, non-existent directory.
419:
420: - Fixed the conversion of spaces into dashes in the %M log escape.
421:
422: - Fixed several places in the code that were not returning the right
423: errno when a function failed.
424:
425: - Fixed the backing up of a device or special file into a backup dir.
426:
427: - Moved the setting of the socket options prior to the connect().
428:
429: - If rsync exits in the middle of a --progress output, it now outputs a
430: newline to help prevent the progress line from being overwritten.
431:
432: - Fixed a problem with how a destination path with a trailing slash or
433: a trailing dot-dir was compared against the daemon excludes.
434:
435: - Fixed the sending of large (size > 16GB) files when talking to an older
436: rsync (protocols < 30): we now use a compatible block size limit.
437:
438: - If a file's length is so huge that we overflow a checksum buffer count
439: (i.e. several hundred TB), warn the user and avoid sending an invalid
440: checksum struct over the wire.
441:
442: - If a source arg is excluded, --relative no longer adds the excluded
443: arg's implied dirs to the transfer. This fix also made the exclude
444: check happen in the better place in the sending code.
445:
446: - Use the overflow_exit() function for overflows, not out_of_memory().
447:
448: - Improved the code to better handle a system that has only 32-bit file
449: offsets.
450:
451: ENHANCEMENTS:
452:
453: - The rsyncd.conf manpage now consistently refers to the parameters in
454: the daemon config file as "parameters".
455:
456: - The description of the --inplace option was improved.
457:
458: EXTRAS:
459:
460: - Added a new script in the support directory, deny-rsync, which allows
461: an admin to (temporarily) replace the rsync command with a script that
462: sends an error message to the remote client via the rsync protocol.
463:
464: DEVELOPER RELATED:
465:
466: - Fixed a testcase failure if the tests are run as root and made some
467: compatibility improvements.
468:
469: - Improved the daemon tests, including checking module comments, the
470: listing of files, and the ensuring that daemon excludes can't affect
471: a dot-dir arg.
472:
473: - Improved some build rules for those that build in a separate directory
474: from the source, including better install rules for the man pages, and
475: the fixing of a proto.h-tstamp rule that could make the binaries get
476: rebuild without cause.
477:
478: - Improved the testsuite to work around a problem with some utilities
479: (e.g. cp -p & touch -r) rounding sub-second timestamps.
480:
481: - Ensure that the early patches don't cause any generated-file hunks to
482: bleed-over into patches that follow.

485: NEWS for rsync 3.0.2 (8 Apr 2008)
486: Protocol: 30 (unchanged)
487: Changes since 3.0.1:
488:
489: BUG FIXES:
490:
491: - Fixed a potential buffer overflow in the xattr code.
492:
493: ENHANCEMENTS:
494:
495: - None.
496:
497: DEVELOPER RELATED:
498:
499: - The RPM spec file was improved to install more useful files.
500:
501: - A few developer-oriented scripts were moved from the support dir
502: to the packaging dir.
503:
504:
505: NEWS for rsync 3.0.1 (3 Apr 2008)
506: Protocol: 30 (unchanged)
507: Changes since 3.0.0:
508:
509: NOTABLE CHANGES IN BEHAVIOR:
510:
511: - Added the 'c'-flag to the itemizing of non-regular files so that the
512: itemized output doesn't get hidden if there were no attribute changes,
513: and also so that the itemizing of a --copy-links run will distinguish
514: between copying an identical non-regular file and the creation of a
515: revised version with a new value (e.g. a changed symlink referent, a
516: new device number, etc.).
517:
518: BUG FIXES:
519:
520: - Fixed a crash bug when a single-use rsync daemon (via remote shell) was
521: run without specifying a --config=FILE option.
522:
523: - Fixed a crash when backing up a directory that has a default ACL.
524:
525: - Fixed a bug in the handling of xattr values that could cause rsync to
526: not think that a file's extended attributes are up-to-date.
527:
528: - Fixed the working of --fake-super with --link-dest and --xattrs.
529:
530: - Fixed a hang when combining --dry-run with --remove-source-files.
531:
532: - Fixed a bug with --iconv's handling of files that cannot be converted:
533: a failed name can no longer cause a transfer failure.
534:
535: - Fixed the building of the rounding.h file on systems that need custom
536: CPPFLAGS to be used. Also improved the error reporting if the building
537: of rounding.h fails.
538:
539: - Fixed the use of the --protect-args (-s) option when talking to a daemon.
540:
541: - Fixed the --ignore-existing option's protection of files on the receiver
542: that are non-regular files on the sender (e.g. if a symlink or a dir on
543: the sender is trying to replace a file on the receiver). The reverse
544: protection (protecting a dir/symlink/device from being replaced by a
545: file) was already working.
546:
547: - Fixed an assert failure if --hard-links is combined with an option that
548: can skip a file in a set of hard-linked files (i.e. --ignore-existing,
549: --append, etc.), without skipping all the files in the set.
550:
551: - Avoid setting the modify time on a directory that already has the right
552: modify time set. This avoids tweaking the dir's ctime.
553:
554: - Improved the daemon-exclude handling to do a better job of applying the
555: exclude rules to path entries. It also sends the user an error just as
556: if the files were actually missing (instead of silently ignoring the
557: user's args), and avoids sending the user the filter-action messages
558: for these non-user-initiated rules.
559:
560: - Fixed some glitches with the dry-run code's missing-directory
561: handling, including a problem when combined with --fuzzy.
562:
563: - Fixed some glitches with the skipped-directory handling.
564:
565: - Fixed the 'T'-flag itemizing of symlinks when --time isn't preserved.
566:
567: - Fixed a glitch in the itemizing of permissions with the -E option.
568:
569: - The --append option's restricting of transfers to those that add data no
570: longer prevents the updating of non-content changes to otherwise up-to-
571: date files (i.e. those with the same content but differing permissions,
572: ownership, xattrs, etc.).
573:
574: - Don't allow --fake-super to be specified with -XX (double --xattrs)
575: because the options conflict. If a daemon has "fake super" enabled,
576: it automatically downgrades a -XX request to -X.
577:
578: - Fixed a couple bugs in the parsing of daemon-config excludes that could
579: make a floating exclude rule get treated as matching an absolute path.
580:
581: - A daemon doesn't try to auto-refuse the "iconv" option if iconv-support
582: wasn't compiled in to the daemon (avoiding a warning in the logs).
583:
584: - Fixed the inclusion of per-dir merge files from implied dirs.
585:
586: - Fixed the support/rrsync script to work with the latest options that
587: rsync sends (including its flag-specifying use of -e to the server).
588:
589: ENHANCEMENTS:
590:
591: - Added the --old-dirs (--old-d) option to make it easier for a user to
592: ask for file-listings with older rsync versions (this is easier than
593: having to type "-r --exclude='/*/*'" manually).
594:
595: - When getting an error while asking an older rsync daemon for a file
596: listing, rsync will try to notice if the error is a rejection of the
597: --dirs (-d) option and let the user know how to work around the issue.
598:
599: - Added a few more --no-OPTION overrides.
600:
601: - Improved the documentation of the --append option.
602:
603: - Improved the documentation of the filter/exclude/include daemon
604: parameters.
605:
606: INTERNAL:
607:
608: - Fixed a couple minor bugs in the included popt library (ones which I
609: sent to the official popt project for inclusion in the 1.14 release).
610:
611: - Fixed a stat() call that should have been do_stat() so that the proper
612: normal/64-bit stat() function gets called. (Was in an area that should
613: not have caused problems, though.)
614:
615: - Changed the file-glob code to do a directory scan without using the
616: "glob" and "glob.h". This lets us do the globbing with less memory
617: churn, and also avoid adding daemon-excluded items to the returned
618: args.
619:
620: DEVELOPER RELATED:
621:
622: - The configure script tries to get the user's compiler to not warn about
623: unused function parameters if the build is not including one or more of
624: the ACL/xattrs/iconv features.
625:
626: - The configure script now has better checks for figuring out if the
627: included popt code should be used or not.
628:
629: - Fixed two testsuite glitches: avoid a failure if someone's "cd" command
630: outputs the current directory when cd-ing to a relative path, and made
631: the itemized test query how rsync was built to determine if it should
632: expect hard-linked symlinks or not.
633:
634: - Updated the testsuite to verify that various bug fixes remain fixed.
635:
636: - The RPM spec file was updated to have: (1) comments for how to use the
637: rsync-patch tar file, and (2) an /etc/xinetd.d/rsync file.
638:
639: - Updated the build scripts to work with a revised FTP directory
640: structure.

643: NEWS for rsync 3.0.0 (1 Mar 2008)
644: Protocol: 30 (changed)
645: Changes since 2.6.9:
646:
647: NOTABLE CHANGES IN BEHAVIOR:
648:
649: - The handling of implied directories when using --relative has changed to
650: send them as directories (e.g. no implied dir is ever sent as a symlink).
651: This avoids unexpected behavior and should not adversely affect most
652: people. If you're one of those rare individuals who relied upon having
653: an implied dir be duplicated as a symlink, you should specify the
654: transfer of the symlink and the transfer of the referent directory as
655: separate args. (See also --keep-dirlinks and --no-implied-dirs.)
656: Also, exclude rules no longer have a partial effect on implied dirs.
657:
658: - Requesting a remote file-listing without specifying -r (--recursive) now
659: sends the -d (--dirs) option to the remote rsync rather than sending -r
660: along with an extra exclude of /*/*. If the remote rsync does not
661: understand the -d option (i.e. it is 2.6.3 or older), you will need to
662: either turn off -d (--no-d), or specify -r --exclude='/*/*' manually.
663:
664: - In --dry-run mode, the last line of the verbose summary text is output
665: with a "(DRY RUN)" suffix to help remind you that no updates were made.
666: Similarly, --only-write-batch outputs "(BATCH ONLY)".
667:
668: - A writable rsync daemon with "use chroot" disabled now defaults to a
669: symlink-munging behavior designed to make symlinks safer while also
670: allowing absolute symlinks to be stored and retrieved. This also has
671: the effect of making symlinks unusable while they're in the daemon's
672: hierarchy. See the daemon's "munge symlinks" parameter for details.
673:
674: - Starting up an extra copy of an rsync daemon will not clobber the pidfile
675: for the running daemon -- if the pidfile exists, the new daemon will exit
676: with an error. This means that your wrapper script that starts the rsync
677: daemon should be made to handle lock-breaking (if you want any automatic
678: breaking of locks to be done).
679:
680: BUG FIXES:
681:
682: - A daemon with "use chroot = no" and excluded items listed in the daemon
683: config file now properly checks an absolute-path arg specified for these
684: options: --compare-dest, --link-dest, --copy-dest, --partial-dir,
685: --backup-dir, --temp-dir, and --files-from.
686:
687: - A daemon can now be told to disable all user- and group-name translation
688: on a per-module basis. This avoids a potential problem with a writable
689: daemon module that has "use chroot" enabled -- if precautions weren't
690: taken, a user could try to add a missing library and get rsync to use
691: it. This makes rsync safer by default, and more configurable when id-
692: translation is not desired. See the daemon's "numeric ids" parameter
693: for full details.
694:
695: - A chroot daemon can now indicate which part of its path should affect the
696: chroot call, and which part should become an inside-chroot path for the
697: module. This allows you to have outside-the-transfer paths (such as for
698: libraries) even when you enable chroot protection. The idiom used in the
699: rsyncd.conf file is: path = /chroot/dirs/./dirs/inside
700:
701: - If a file's data arrived successfully on the receiving side but the
702: rename of the temporary file to the destination file failed AND the
703: --remove-source-files (or the deprecated --remove-sent-files) option
704: was specified, rsync no longer erroneously removes the associated
705: source file.
706:
707: - Fixed the output of -ii when combined with one of the --*-dest options:
708: it now itemizes all the items, not just the changed ones.
709:
710: - Made the output of all file types consistent when using a --*-dest
711: option. Prior versions would output too many creation events for
712: matching items.
713:
714: - The code that waits for a child pid now handles being interrupted by a
715: signal. This fixes a problem with the pre-xfer exec function not being
716: able to get the exit status from the script.
717:
718: - A negated filter rule (i.e. with a '!' modifier) no longer loses the
719: negation when sending the filter rules to the remote rsync.
720:
721: - Fixed a problem with the --out-format (aka --log-format) option %f: it
722: no longer outputs superfluous directory info for a non-daemon rsync.
723:
724: - Fixed a problem with -vv (double --verbose) and --stats when "pushing"
725: files (which includes local copies). Version 2.6.9 would complete the
726: copy, but exit with an error when the receiver output its memory stats.
727:
728: - If --password-file is used on a non-daemon transfer, rsync now complains
729: and exits. This should help users figure out that they can't use this
730: option to control a remote shell's password prompt.
731:
732: - Make sure that directory permissions of a newly-created destination
733: directory are handled right when --perms is left off.
734:
735: - The itemized output of a newly-created destination directory is now
736: output as a creation event, not a change event.
737:
738: - Improved --hard-link so that more corner cases are handled correctly
739: when combined with options such as --link-dest and/or --ignore-existing.
740:
741: - The --append option no longer updates a file that has the same size.
742:
743: - Fixed a bug when combining --backup and --backup-dir with --inplace:
744: any missing backup directories are now created.
745:
746: - Fixed a bug when using --backup and --inplace with --whole-file or
747: --read-batch: backup files are actually created now.
748:
749: - The daemon pidfile is checked and created sooner in the startup sequence.
750:
751: - If a daemon module's "path" value is not an absolute pathname, the code
752: now makes it absolute internally (making it work properly).
753:
754: - Ensure that a temporary file always has owner-write permission while we
755: are writing to it. This avoids problems with some network filesystems
756: when transfering read-only files.
757:
758: - Any errors output about password-file reading no longer cause an error at
759: the end of the run about a partial transfer.
760:
761: - The --read-batch option for protocol 30 now ensures that several more
762: options are set correctly for the current batch file: --iconv, --acls,
763: --xattrs, --inplace, --append, and --append-verify.
764:
765: - Using --only-write-batch to a daemon receiver now works properly (older
766: versions would update some files while writing the batch).
767:
768: - Avoid outputting a "file has vanished" message when the file is a broken
769: symlink and --copy-unsafe-links or --copy-dirlinks is used (the code
770: already handled this for --copy-links).
771:
772: - Fixed the combination of --only-write-batch and --dry-run.
773:
774: - Fixed rsync's ability to remove files that are not writable by the file's
775: owner when rsync is running as the same user.
776:
777: - When transferring large files, the sender's hashtable of checksums is
778: kept at a more reasonable state of fullness (no more than 80% full) so
779: that the scanning of the hashtable will not bog down as the number of
780: blocks increases.
781:
782: ENHANCEMENTS:
783:
784: - A new incremental-recursion algorithm is now used when rsync is talking
785: to another 3.x version. This starts the transfer going more quickly
786: (before all the files have been found), and requires much less memory.
787: See the --recursive option in the manpage for some restrictions.
788:
789: - Lowered memory use in the non-incremental-recursion algorithm for typical
790: option values (usually saving from 21-29 bytes per file).
791:
792: - The default --delete algorithm is now --delete-during when talking to a
793: 3.x rsync. This is a faster scan than using --delete-before (which is
794: the default when talking to older rsync versions), and is compatible with
795: the new incremental recursion mode.
796:
797: - Rsync now allows multiple remote-source args to be specified rather than
798: having to rely on a special space-splitting side-effect of the remote-
799: shell. Additional remote args must specify the same host or an empty one
800: (e.g. empty: :file1 or ::module/file2). For example, this means that
801: local use of brace expansion now works: rsync -av host:dir/{f1,f2} .
802:
803: - Added the --protect-args (-s) option, that tells rsync to send most of
804: the command-line args at the start of the transfer rather than as args
805: to the remote-shell command. This protects them from space-splitting,
806: and only interprets basic wildcard special shell characters (*?[).
807:
808: - Added the --delete-delay option, which is a more efficient way to delete
809: files at the end of the transfer without needing a separate delete pass.
810:
811: - Added the --acls (-A) option to preserve Access Control Lists. This is
812: an improved version of the prior patch that was available, and it even
813: supports OS X ACLs. If you need to have backward compatibility with old,
814: ACL-patched versions of rsync, apply the acls.diff file from the patches
815: dir.
816:
817: - Added the --xattrs (-X) option to preserve extended attributes. This is
818: an improved version of the prior patch that was available, and it even
819: supports OS X xattrs (which includes their resource fork data). If you
820: need to have backward compatibility with old, xattr-patched versions of
821: rsync, apply the xattrs.diff file from the patches dir.
822:
823: - Added the --fake-super option that allows a non-super user to preserve
824: all attributes of a file by using a special extended-attribute idiom.
825: It even supports the storing of foreign ACL data on your backup server.
826: There is also an analogous "fake super" parameter for an rsync daemon.
827:
828: - Added the --iconv option, which allows rsync to convert filenames from
829: one character-set to another during the transfer. The default is to
830: make this feature available as long as your system has iconv_open().
831: If compilation fails, specify --disable-iconv to configure, and then
832: rebuild. If you want rsync to perform character-set conversions by
833: default, you can specify --enable-iconv=CONVERT_STRING with the default
834: value for the --iconv option that you wish to use. For example,
835: "--enable-iconv=." is a good choice. See the rsync manpage for an
836: explanation of the --iconv option's settings.
837:
838: - A new daemon config parameter, "charset", lets you control the character-
839: set that is used during an --iconv transfer to/from a daemon module. You
840: can also set your daemon to refuse "no-iconv" if you want to force the
841: client to use an --iconv transfer (requiring an rsync 3.x client).
842:
843: - Added the --skip-compress=LIST option to override the default list of
844: file suffixes that will not be compressed when using --compress (-z).
845:
846: - The daemon's default for "dont compress" was extended to include:
847: *.7z *.mp[34] *.mov *.avi *.ogg *.jpg *.jpeg
848: The name-matching routine was also optimized to run more quickly.
849:
850: - The --max-delete option now outputs a warning if it skipped any file
851: deletions, including a count of how many deletions were skipped. (Older
852: versions just silently stopped deleting things.)
853:
854: - You may specify --max-delete=0 to a 3.0.0 client to request that it warn
855: about extraneous files without deleting anything. If you're not sure
856: what version the client is, you can use the less-obvious --max-delete=-1,
857: as both old and new versions will treat that as the same request (though
858: older versions don't warn).
859:
860: - The --hard-link option now uses less memory on both the sending and
861: receiving side for all protocol versions. For protocol 30, the use of a
862: hashtable on the sending side allows us to more efficiently convey to the
863: receiver what files are linked together. This reduces the amount of data
864: sent over the socket by a considerable margin (rather than adding more
865: data), and limits the in-memory storage of the device+inode information
866: to just the sending side for the new protocol 30, or to the receiving
867: side when speaking an older protocol (note that older rsync versions kept
868: the device+inode information on both sides).
869:
870: - The filter rules now support a perishable ("p") modifier that marks rules
871: that should not have an effect in a directory that is being deleted. e.g.
872: -f '-p .svn/' would only affect "live" .svn directories.
873:
874: - Rsync checks all the alternate-destination args for validity (e.g.
875: --link-dest). This lets the user know when they specified a directory
876: that does not exist.
877:
878: - If we get an ENOSYS error setting the time on a symlink, we don't
879: complain about it anymore (for those systems that even support the
880: setting of the modify-time on a symlink).
881:
882: - Protocol 30 now uses MD5 checksums instead of MD4.
883:
884: - Changed the --append option to not checksum the existing data in the
885: destination file, which speeds up file appending.
886:
887: - Added the --append-verify option, which works like the older --append
888: option (verifying the existing data in the destination file). For
889: compatibility with older rsync versions, any use of --append that is
890: talking protocol 29 or older will revert to the --append-verify method.
891:
892: - Added the --contimeout=SECONDS option that lets the user specify a
893: connection timeout for rsync daemon access.
894:
895: - Documented and extended the support for the RSYNC_CONNECT_PROG variable
896: that can be used to enhance the client side of a daemon connection.
897:
898: - Improved the dashes and double-quotes in the nroff manpage output.
899:
900: - Rsync now supports a lot more --no-OPTION override options.
901:
902: INTERNAL:
903:
904: - The file-list sorting algorithm now uses a sort that keeps any same-
905: named items in the same order as they were specified. This allows
906: rsync to always ensure that the first of the duplicates is the one
907: that will be included in the copy. The new sort is also faster
908: than the glibc version of qsort() and mergesort().
909:
910: - Rsync now supports the transfer of 64-bit timestamps (time_t values).
911:
912: - Made the file-deletion code use a little less stack when recursing
913: through a directory hierarchy of extraneous files.
914:
915: - Fixed a build problem with older (2.x) versions of gcc.
916:
917: - Added some isType() functions that make dealing with signed characters
918: easier without forcing variables via casts.
919:
920: - Changed strcat/strcpy/sprintf function calls to use safer versions.
921:
922: - Upgraded the included popt version to 1.10.2 and improved its use of
923: string-handling functions.
924:
925: - Added missing prototypes for compatibility functions from the lib dir.
926:
927: - Configure determines if iconv() has a const arg, allowing us to avoid a
928: compiler warning.
929:
930: - Made the sending of some numbers more efficient for protocol 30.
931:
932: - Make sure that a daemon process doesn't mind if the client was weird and
933: omitted the --server option.
934:
935: - There are more internal logging categories available in protocol 30 than
936: the age-old FINFO and FERROR, including FERROR_XFER and FWARN. These new
937: categories allow some errors and warnings to go to stderr without causing
938: an erroneous end-of-run warning about some files not being able to be
939: transferred.
940:
941: - Improved the use of "const" on pointers.
942:
943: - Improved J.W.'s pool_alloc routines to add a way of incrementally freeing
944: older sections of a pool's memory.
945:
946: - The getaddrinfo.c compatibility code in the "lib" dir was replaced with
947: some new code (derived from samba, derived from PostgreSQL) that has a
948: better license than the old code.
949:
950: DEVELOPER RELATED:
951:
952: - Rsync is now licensed under the GPLv3 or later.
953:
954: - Rsync is now being maintained in a "git" repository instead of CVS
955: (though the old CVS repository still exists for historical access).
956: Several maintenance scripts were updated to work with git.
957:
958: - Generated files are no longer committed into the source repository. The
959: autoconf and autoheader commands are now automatically run during the
960: normal use of "configure" and "make". The latest dev versions of all
961: generated files can also be copied from the samba.org web site (see the
962: prepare-source script's fetch option).
963:
964: - The "patches" directory of diff files is now built from branches in the
965: rsync git repository (branch patch/FOO creates file patches/FOO.diff).
966: This directory is now distributed in a separate separate tar file named
967: rsync-patches-VERSION.tar.gz instead of the main rsync-VERSION.tar.gz.
968:
969: - The proto.h file is now built using a simple perl script rather than a
970: complex awk script, which proved to be more widely compatible.
971:
972: - When running the tests, we now put our per-test temp dirs into a sub-
973: directory named testtmp (which is created, if missing). This allows
974: someone to symlink the testtmp directory to another filesystem (which is
975: useful if the build dir's filesystem does not support ACLs and xattrs,
976: but another filesystem does).
977:
978: - Rsync now has a way of handling protocol-version changes during the
979: development of a new protocol version. This causes any out-of-sync
980: versions to speak an older protocol rather than fail in a cryptic manner.
981: This addition makes it safer to deploy a pre-release version that may
982: interact with the public. This new exchange of sub-version info does not
983: interfere with the {MIN,MAX}_PROTOCOL_VERSION checking algorithm (which
984: does not have enough range to allow the main protocol number to be
985: incremented for every minor tweak in that happens during development).
986:
987: - The csprotocol.txt file was updated to mention the daemon protocol change
988: in the 3.0.0 release.
989:
990:
991: NEWS for rsync 2.6.9 (6 Nov 2006)
992: Protocol: 29 (unchanged)
993: Changes since 2.6.8:
994:
995: BUG FIXES:
996:
997: - If rsync is interrupted via a handled signal (such as SIGINT), it will
998: once again clean-up its temp file from the destination dir.
999:
1000: - Fixed an overzealous sanitizing bug in the handling of the --link-dest,
1001: --copy-dest, and --compare-dest options to a daemon without chroot: if
1002: the copy's destination dir is deeper than the top of the module's path,
1003: these options now accept a safe number of parent-dir (../) references
1004: (since these options are relative to the destination dir). The old code
1005: incorrectly chopped off all "../" prefixes for these options, no matter
1006: how deep the destination directory was in the module's hierarchy.
1007:
1008: - Fixed a bug where a deferred info/error/log message could get sent
1009: directly to the sender instead of being handled by rwrite() in the
1010: generator. This fixes an "unexpected tag 3" fatal error, and should
1011: also fix a potential problem where a deferred info/error message from
1012: the receiver might bypass the log file and get sent only to the client
1013: process. (These problems could only affect an rsync daemon that was
1014: receiving files.)
1015:
1016: - Fixed a bug when --inplace was combined with a --*-dest option and we
1017: update a file's data using an alternate basis file. The code now
1018: notices that it needs to copy the matching data from the basis file
1019: instead of (wrongly) assuming that it was already present in the file.
1020:
1021: - Fixed a bug where using --dry-run with a --*-dest option with a path
1022: relative to a directory that does not yet exist: the affected option
1023: gets its proper path value so that the output of the dry-run is right.
1024:
1025: - Fixed a bug in the %f logfile escape when receiving files: the
1026: destination path is now included in the output (e.g. you can now tell
1027: when a user specifies a subdir inside a module).
1028:
1029: - If the receiving side fails to create a directory, it will now skip
1030: trying to update everything that is inside that directory.
1031:
1032: - If --link-dest is specified with --checksum but without --times, rsync
1033: will now allow a hard-link to be created to a matching link-dest file
1034: even when the file's modify-time doesn't match the server's file.
1035:
1036: - The daemon now calls more timezone-using functions prior to doing a
1037: chroot. This should help some C libraries to generate proper timestamps
1038: from inside a chrooted daemon (and to not try to access /etc/timezone
1039: over and over again).
1040:
1041: - Fixed a bug in the handling of an absolute --partial-dir=ABS_PATH option:
1042: it now deletes an alternate basis file from the partial-dir that was used
1043: to successfully update a destination file.
1044:
1045: - Fixed a bug in the handling of --delete-excluded when using a per-dir
1046: merge file: the merge file is now honored on the receiving side, and
1047: only its unqualified include/exclude commands are ignored (just as is
1048: done for global include/excludes).
1049:
1050: - Fixed a recent bug where --delete was not working when transferring from
1051: the root (/) of the filesystem with --relative enabled.
1052:
1053: - Fixed a recent bug where an --exclude='*' could affect the root (/) of
1054: the filesystem with --relative enabled.
1055:
1056: - When --inplace creates a file, it is now created with owner read/write
1057: permissions (0600) instead of no permissions at all. This avoids a
1058: problem continuing a transfer that was interrupted (since --inplace
1059: will not update a file that has no write permissions).
1060:
1061: - If either --remove-source-files or --remove-sent-files is enabled and we
1062: are unable to remove the source file, rsync now outputs an error.
1063:
1064: - Fixed a bug in the daemon's "incoming chmod" rule: newly-created
1065: directories no longer get the 'F' (file) rules applied to them.
1066:
1067: - Fixed an infinite loop bug when a filter rule was rejected due to being
1068: overly long.
1069:
1070: - When the server receives a --partial-dir option from the client, it no
1071: longer runs the client-side code that adds an assumed filter rule (since
1072: the client will be sending us the rules in the usual manner, and they
1073: may have chosen to override the auto-added rule).
1074:
1075: ENHANCEMENTS:
1076:
1077: - Added the --log-file=FILE and --log-file-format=FORMAT options. These
1078: can be used to tell any rsync to output what it is doing to a log file.
1079: They work with a client rsync, a non-daemon server rsync (see the man
1080: page for instructions), and also allows the overriding of rsyncd.conf
1081: settings when starting a daemon.
1082:
1083: - The --log-format option was renamed to be --out-format to avoid confusing
1084: it with affecting the log-file output. (The old option remains as an
1085: alias for the new to preserve backward compatibility.)
1086:
1087: - Made "log file" and "syslog facility" settable on a per-module basis in
1088: the daemon's config file.
1089:
1090: - Added the --remove-source-files option as a replacement for the (now
1091: deprecated) --remove-sent-files option. This new option removes all
1092: non-dirs from the source directories, even if the file was already
1093: up-to-date. This fixes a problem where interrupting an rsync that
1094: was using --remove-sent-files and restarting it could leave behind
1095: a file that the earlier rsync synchronized, but didn't get to remove.
1096: (The deprecated --remove-sent-files is still understood for now, and
1097: still behaves in the same way as before.)
1098:
1099: - Added the option --no-motd to suppress the message-of-the-day output
1100: from a daemon when doing a copy. (See the manpage for a caveat.)
1101:
1102: - Added a new environment variable to the pre-/post-xfer exec commands (in
1103: the daemon's config file): RSYNC_PID. This value will be the same in
1104: both the pre- and post-xfer commands, so it can be used as a unique ID
1105: if the pre-xfer command wants to cache some arg/request info for the
1106: post-xfer command.
1107:
1108: INTERNAL:
1109:
1110: - Did a code audit using IBM's code-checker program and made several
1111: changes, including: replacing most of the strcpy() and sprintf()
1112: calls with strlcpy(), snprintf(), and memcpy(), adding a 0-value to
1113: an enum that had been intermingling a literal 0 with the defined enum
1114: values, silencing some uninitialized memory checks, marking some
1115: functions with a "noreturn" attribute, and changing an "if" that
1116: could never succeed on some platforms into a pre-processor directive
1117: that conditionally compiles the code.
1118:
1119: - Fixed a potential bug in f_name_cmp() when both the args are a
1120: top-level "." dir (which doesn't happen in normal operations).
1121:
1122: - Changed exit_cleanup() so that it can never return instead of exit.
1123: The old code might return if it found the exit_cleanup() function
1124: was being called recursively. The new code is segmented so that
1125: any recursive calls move on to the next step of the exit-processing.
1126:
1127: - The macro WIFEXITED(stat) will now be defined if the OS didn't already
1128: define it.
1129:
1130: DEVELOPER RELATED:
1131:
1132: - The acls.diff and xattrs.diff patches have received a bunch of work to
1133: make them much closer to being acceptable in the main distribution.
1134: The xattrs patch also has some preliminary Mac OS X and FreeBSD
1135: compatibility code that various system types to exchange extended
1136: file-attributes.
1137:
1138: - A new diff in the patches dir, fake-root.diff, allows rsync to
1139: maintain a backup hierarchy with full owner, group, and device info
1140: without actually running as root. It does this using a special
1141: extended attribute, so it depends on xattrs.diff (which depends on
1142: acls.diff).
1143:
1144: - The rsync.yo and rsyncd.conf.yo files have been updated to work
1145: better with the latest yodl 2.x releases.
1146:
1147: - Updated config.guess and config.sub to their 2006-07-02 versions.
1148:
1149: - Updated various files to include the latest FSF address and to have
1150: consistent opening comments.

1153: NEWS for rsync 2.6.8 (22 Apr 2006)
1154: Protocol: 29 (unchanged)
1155: Changes since 2.6.7:
1156:
1157: BUG FIXES:
1158:
1159: - Fixed a bug in the exclude code where an anchored exclude without any
1160: wildcards fails to match an absolute source arg, but only when --relative
1161: is in effect.
1162:
1163: - Improved the I/O code for the generator to fix a potential hang when the
1164: receiver gets an EOF on the socket but the generator's select() call
1165: never indicates that the socket is writable for it to be notified about
1166: the EOF. (This can happen when using stunnel).
1167:
1168: - Fixed a problem with the file-reading code where a failed read (such as
1169: that caused by a bad sector) would not advance the file's read-position
1170: beyond the failed read's data.
1171:
1172: - Fixed a logging bug where the "log file" directive was not being honored
1173: in a single-use daemon (one spawned by a remote-shell connection or by
1174: init).
1175:
1176: - If rsync cannot honor the --delete option, we output an error and exit
1177: instead of silently ignoring the option.
1178:
1179: - Fixed a bug in the --link-dest code that prevented special files (such as
1180: fifos) from being linked.
1181:
1182: - The ability to hard-link symlinks and special files is now determined at
1183: configure time instead of at runtime. This fixes a bug with --link-dest
1184: creating a hard-link to a symlink's referent on a BSD system.
1185:
1186: ENHANCEMENTS:
1187:
1188: - In daemon mode, if rsync fails to bind to the requested port, the
1189: error(s) returned by socket() and/or bind() are now logged.
1190:
1191: - When we output a fatal error, we now output the version of rsync in the
1192: message.
1193:
1194: - Improved the documentation for the --owner and --group options.
1195:
1196: - The rsyncstats script in "support" has an improved line-parsing regex
1197: that is easier to read and also makes it to parse syslog-generated lines.
1198:
1199: - A new script in "support": file-attr-restore, can be used to restore the
1200: attributes of a file-set (the permissions, ownership, and group info)
1201: taken from the cached output of a "find ARG... -ls" command.
1202:
1203: DEVELOPER RELATED:
1204:
1205: - Removed the unused function write_int_named(), the unused variable
1206: io_read_phase, and the rarely used variable io_write_phase. This also
1207: elides the confusing 'phase "unknown"' part of one error message.
1208:
1209: - Removed two unused configure checks and two related (also unused)
1210: compatibility functions.
1211:
1212: - The xattrs.diff patch received a security fix that prevents a potential
1213: buffer overflow in the receive_xattr() code.
1214:
1215: - The acls.diff patch has been improved quite a bit, with more to come.
1216:
1217: - A new patch was added: log-file.diff. This contains an early version of
1218: a future option, --log-file=FILE, that will allow any rsync to log its
1219: actions to a file (something that only a daemon supports at present).
1220:
1221:
1222: NEWS for rsync 2.6.7 (11 Mar 2006)
1223: Protocol: 29 (unchanged)
1224: Changes since 2.6.6:
1225:
1226: OUTPUT CHANGES:
1227:
1228: - The letter 'D' in the itemized output was being used for both devices
1229: (character or block) as well as other special files (such as fifos and
1230: named sockets). This has changed to separate non-device special files
1231: under the 'S' designation (e.g. "cS+++++++ path/fifo"). See also the
1232: "--specials" option, below.
1233:
1234: - The way rsync escapes unreadable characters has changed. First, rsync
1235: now has support for recognizing valid multibyte character sequences in
1236: your current locale, allowing it to escape fewer characters than before
1237: for a locale such as UTF-8. Second, it now uses an escape idiom of
1238: "\#123", which is the literal string "\#" followed by exactly 3 octal
1239: digits. Rsync no longer doubles a backslash character in a filename
1240: (e.g. it used to output "foo\\bar" when copying "foo\bar") -- now it only
1241: escapes a backslash that is followed by a hash-sign and 3 digits (0-9)
1242: (e.g. it will output "foo\#134#789" when copying "foo\#789"). See also
1243: the --8-bit-output (-8) option, mentioned below.
1244:
1245: Script writers: the local rsync is the one that outputs escaped names,
1246: so if you need to support unescaping of filenames for older rsyncs, I'd
1247: suggest that you parse the output of "rsync --version" and only use the
1248: old unescaping rules for 2.6.5 and 2.6.6.
1249:
1250: BUG FIXES:
1251:
1252: - Fixed a really old bug that caused --checksum (-c) to checksum all the
1253: files encountered during the delete scan (ouch).
1254:
1255: - Fixed a potential hang in a remote generator: when the receiver gets a
1256: read-error on the socket, it now signals the generator about this so that
1257: the generator does not try to send any of the terminating error messages
1258: to the client (avoiding a potential hang in some setups).
1259:
1260: - Made hard-links work with symlinks and devices again.
1261:
1262: - If the sender gets an early EOF reading a source file, we propagate this
1263: error to the receiver so that it can discard the file and try requesting
1264: it again (which is the existing behavior for other kinds of read errors).
1265:
1266: - If a device-file/special-file changes permissions, rsync now updates the
1267: permissions without recreating the file.
1268:
1269: - If the user specifies a remote-host for both the source and destination,
1270: we now output a syntax error rather than trying to open the destination
1271: hostspec as a filename.
1272:
1273: - When --inplace creates a new destination file, rsync now creates it with
1274: permissions 0600 instead of 0000 -- this makes restarting possible when
1275: the transfer gets interrupted in the middle of sending a new file.
1276:
1277: - Reject the combination of --inplace and --sparse since the sparse-output
1278: algorithm doesn't work when overwriting existing data.
1279:
1280: - Fixed the directory name in the error that is output when pop_dir()
1281: fails.
1282:
1283: - Really fixed the parsing of a "!" entry in .cvsignore files this time.
1284:
1285: - If the generator gets a stat() error on a file, output it (this used to
1286: require at least -vv for the error to be seen).
1287:
1288: - If waitpid() fails or the child rsync didn't exit cleanly, we now handle
1289: the exit status properly and generate a better error.
1290:
1291: - Fixed some glitches in the double-verbose output when using --copy-dest,
1292: --link-dest, or --compare-dest. Also improved how the verbose output
1293: handles hard-links (within the transfer) that had an up-to-date alternate
1294: "dest" file, and copied files (via --copy-dest).
1295:
1296: - Fixed the matching of the dont-compress items (e.g. *.gz) against files
1297: that have a path component containing a slash.
1298:
1299: - If the code reading a filter/exclude file gets an EINTR error, rsync now
1300: clears the error flag on the file handle so it can keep on reading.
1301:
1302: - If --relative is active, the sending side cleans up trailing "/" or "/."
1303: suffixes to avoid triggering a bug in older rsync versions. Also, we now
1304: reject a ".." dir if it would be sent as a relative dir.
1305:
1306: - If a non-directory is in the way of a directory and rsync is run with
1307: --dry-run and --delete, rsync no longer complains about not being able
1308: to opendir() the not-yet present directory.
1309:
1310: - When --list-only is used and a non-existent local destination dir was
1311: also specified as a destination, rsync no longer generates a warning
1312: about being unable to create the missing directory.
1313:
1314: - Fixed some problems with --relative --no-implied-dirs when the
1315: destination directory did not yet exist: we can now create a symlink or
1316: device when it is the first thing in the missing dir, and --fuzzy no
1317: longer complains about being unable to open the missing dir.
1318:
1319: - Fixed a bug where the --copy-links option would not affect implied
1320: directories without --copy-unsafe-links (see --relative).
1321:
1322: - Got rid of the need for --force to be used in some circumstances with
1323: --delete-after (making it consistent with --delete-before/-during).
1324:
1325: - Rsync now ignores the SIGXFSZ signal, just in case your OS sends this
1326: when a file is too large (rsync handles the write error).
1327:
1328: - Fixed a bug in the Proxy-Authorization header's base64-encoded value: it
1329: was not properly padded with trailing '=' chars. This only affects a
1330: user that need to use a password-authenticated proxy for an outgoing
1331: daemon-rsync connection.
1332:
1333: - If we're transferring an empty directory to a new name, rsync no longer
1334: forces S_IWUSR if it wasn't already set, nor does it accidentally leave
1335: it set.
1336:
1337: - Fixed a bug in the debug output (-vvvvv) that could mention the wrong
1338: checksum for the current file offset.
1339:
1340: - Rsync no longer allows a single directory to be copied over a non-
1341: directory destination arg.
1342:
1343: ENHANCEMENTS:
1344:
1345: - Added the --append option that makes rsync append data onto files that
1346: are longer on the source than the destination (this includes new files).
1347:
1348: - Added the --min-size=SIZE option to exclude small files from the
1349: transfer.
1350:
1351: - Added the --compress-level option to allow you to set how aggressive
1352: rsync's compression should be (this option implies --compress).
1353:
1354: - Enhanced the parsing of the SIZE value for --min-size and --max-size to
1355: allow easy entry of multiples of 1000 (instead of just multiples of 1024)
1356: and off-by-one values too (e.g. --max-size=8mb-1).
1357:
1358: - Added the --8-bit-output (-8) option, which tells rsync to avoid escaping
1359: high-bit characters that it thinks are unreadable in the current locale.
1360:
1361: - The new option --human-readable (-h) changes the output of --progress,
1362: --stats, and the end-of-run summary to be easier to read. If repeated,
1363: the units become powers of 1024 instead of powers of 1000. (The old
1364: meaning of -h, as a shorthand for --help, still works as long as you
1365: just use it on its own, as in "rsync -h".)
1366:
1367: - If lutimes() and/or lchmod() are around, use them to allow the
1368: preservation of attributes on symlinks.
1369:
1370: - The --link-dest option now affects symlinks and devices (when possible).
1371:
1372: - Added two config items to the rsyncd.conf parsing: "pre-xfer exec" and
1373: "post-xfer exec". These allow a command to be specified on a per-module
1374: basis that will be run before and/or after a daemon-mode transfer. (See
1375: the man page for a list of the environment variables that are set with
1376: information about the transfer.)
1377:
1378: - When using the --relative option, you can now insert a dot dir in
1379: the source path to indicate where the replication of the source dirs
1380: should start. For example, if you specify a source path of
1381: rsync://host/module/foo/bar/./baz/dir with -R, rsync will now only
1382: replicate the "baz/dir" part of the source path (note: a trailing
1383: dot dir is unaffected unless it also has a trailing slash).
1384:
1385: - Added some new --no-FOO options that make it easier to override unwanted
1386: implied or default options. For example, "-a --no-o" (aka "--archive
1387: --no-owner") can be used to turn off the preservation of file ownership
1388: that is implied by -a.
1389:
1390: - Added the --chmod=MODE option that allows the destination permissions to
1391: be changed from the source permissions. E.g. --chmod=g+w,o-rwx
1392:
1393: - Added the "incoming chmod" and "outgoing chmod" daemon options that allow
1394: a module to specify what permissions changes should be applied to all
1395: files copied to and from the daemon.
1396:
1397: - Allow the --temp-dir option to be specified when starting a daemon, which
1398: sets the default temporary directory for incoming files.
1399:
1400: - If --delete is combined with --dirs without --recursive, rsync will now
1401: delete in any directory whose content is being synchronized.
1402:
1403: - If --backup is combined with --delete without --backup-dir (and without
1404: --delete-excluded), we add a "protect" filter-rule to ensure that files
1405: with the backup suffix are not deleted.
1406:
1407: - The file-count stats that are output by --progress were improved to
1408: better indicate what the numbers mean. For instance, the output:
1409: "(xfer#5, to-check=8383/9999)" indicates that this was the fifth file
1410: to be transferred, and we still need to check 8383 more files out of
1411: a total of 9999.
1412:
1413: - The include/exclude code now allows a dir/*** directive (with 3 trailing
1414: stars) to match both the dir itself as well as all the content below the
1415: dir (dir/** would not match the dir).
1416:
1417: - Added the --prune-empty-dirs (-m) option that makes the receiving rsync
1418: discard empty chains of directories from the file-list. This makes it
1419: easier to selectively copy files from a source hierarchy and end up with
1420: just the directories needed to hold the resulting files.
1421:
1422: - If the --itemize-changes (-i) option is repeated, rsync now includes
1423: unchanged files in the itemized output (similar to -vv, but without all
1424: the other verbose messages that can get in the way). Of course, the
1425: client must be version 2.6.7 for this to work, but the remote rsync only
1426: needs to be 2.6.7 if you're pushing files.
1427:
1428: - Added the --specials option to tell rsync to copy non-device special
1429: files (which rsync now attempts even as a normal user). The --devices
1430: option now requests the copying of just devices (character and block).
1431: The -D option still requests both (e.g. --devices and --specials), -a
1432: still implies -D, and non-root users still get a silent downgrade that
1433: omits device copying.
1434:
1435: - Added the --super option to make the receiver always attempt super-user
1436: activities. This is useful for systems that allow things such as devices
1437: to be created or ownership to be set without being UID 0, and is also
1438: useful for someone who wants to ensure that errors will be output if the
1439: receiving rsync isn't being run as root.
1440:
1441: - Added the --sockopts option for those few who want to customize the TCP
1442: options used to contact a daemon rsync.
1443:
1444: - Added a way for the --temp-dir option to be combined with a partial-dir
1445: setting that lets rsync avoid non-atomic updates (for those times when
1446: --temp-dir is not being used because space is tight).
1447:
1448: - A new support script, files-to-excludes, will transform a list of files
1449: into a set of include/exclude directives that will copy those files.
1450:
1451: - A new option, --executability (-E) can be used to preserve just the
1452: execute bit on files, for those times when using the --perms option is
1453: not desired.
1454:
1455: - The daemon now logs each connection and also each module-list request
1456: that it receives.
1457:
1458: - New log-format options: %M (modtime), %U (uid), %G (gid), and %B
1459: (permission bits, e.g. "rwxr-xrwt").
1460:
1461: - The --dry-run option no longer forces the enabling of --verbose.
1462:
1463: - The --remove-sent-files option now does a better job of incrementally
1464: removing the sent files on the sending side (older versions tended to
1465: clump up all the removals at the end).
1466:
1467: - A daemon now supersedes its minimal SIGCHLD handler with the standard
1468: PID-remembering version after forking. This ensures that the generator
1469: can get the child-exit status from the receiver.
1470:
1471: - Use of the --bwlimit option no longer interferes with the remote rsync
1472: sending error messages about invalid/refused options.
1473:
1474: - Rsync no longer returns a usage error when used with one local source arg
1475: and no destination: this now implies the --list-only option, just like
1476: the comparable situation with a remote source arg.
1477:
1478: - Added the --copy-dirlinks option, a more limited version of --copy-links.
1479:
1480: - Various documentation improvements, including: a better synopsis, some
1481: improved examples, a better discussion of the presence and absence of
1482: --perms (including how it interacts with the new --executability and
1483: --chmod options), an extended discussion of --temp-dir, an improved
1484: discussion of --partial-dir, a better description of rsync's pattern
1485: matching characters, an improved --no-implied-dirs section, and the
1486: documenting of what the --stats option outputs.
1487:
1488: - Various new and updated diffs in the patches dir, including: acls.diff,
1489: xattrs.diff, atimes.diff, detect-renamed.diff, and slp.diff.
1490:
1491: INTERNAL:
1492:
1493: - We now use sigaction() and sigprocmask() if possible, and fall back on
1494: signal() if not. Using sigprocmask() ensures that rsync enables all the
1495: signals that it needs, just in case it was started in a masked state.
1496:
1497: - Some buffer sizes were expanded a bit, particularly on systems where
1498: MAXPATHLEN is overly small (e.g. cygwin).
1499:
1500: - If io_printf() tries to format more data than fits in the buffer, exit
1501: with an error instead of transmitting a truncated buffer.
1502:
1503: - If a va_copy macro is defined, lib/snprintf.c will use it when defining
1504: the VA_COPY macro.
1505:
1506: - Reduced the amount of stack memory needed for each level of directory
1507: recursion by nearly MAXPATHLEN bytes.
1508:
1509: - The wildmatch function was extended to allow an array of strings to be
1510: supplied as the string to match. This allows the exclude code to do less
1511: string copying.
1512:
1513: - Got rid of the safe_fname() function (and all the myriad calls) and
1514: replaced it with a new function in the log.c code that filters all the
1515: output going to the terminal.
1516:
1517: - Unified the f_name() and the f_name_to() functions.
1518:
1519: - Improved the hash-table code the sender uses to handle checksums to make
1520: it use slightly less memory and run just a little faster.
1521:
1522: DEVELOPER RELATED:
1523:
1524: - The diffs in the patches dir now require "patch -p1 <DIFF" instead of
1525: the previous -p0. Also, the version included in the release tar now
1526: affect generated files (e.g. configure, rsync.1, proto.h, etc.), so
1527: it is no longer necessary to run autoconf and/or yodl unless you're
1528: applying a patch that was checked out from CVS.
1529:
1530: - Several diffs in the patches dir now use the proper --enable-FOO
1531: configure option instead of --with-FOO to turn on the inclusion of
1532: the newly patched feature.
1533:
1534: - There is a new script, "prepare-source" than can be used to update the
1535: various generated files (proto.h, configure, etc.) even before configure
1536: has created the Makefile (this is mainly useful when patching the source
1537: with a patch that doesn't affect generated files).
1538:
1539: - The testsuite now sets HOME so that it won't be affected by a file such
1540: as ~/.popt.
1541:
1542:
1543: NEWS for rsync 2.6.6 (28 Jul 2005)
1544: Protocol: 29 (unchanged)
1545: Changes since 2.6.5:
1546:
1547: SECURITY FIXES:
1548:
1549: - The zlib code was upgraded to version 1.2.3 in order to make it more
1550: secure. While the widely-publicized security problem in zlib 1.2.2 did
1551: not affect rsync, another security problem surfaced that affects rsync's
1552: zlib 1.1.4.
1553:
1554: BUG FIXES:
1555:
1556: - The setting of flist->high in clean_flist() was wrong for an empty list.
1557: This could cause flist_find() to crash in certain rare circumstances
1558: (e.g. if just the right directory setup was around when --fuzzy was
1559: combined with --link-dest).
1560:
1561: - The outputting of hard-linked files when verbosity was > 1 was not right:
1562: (1) Without -i it would output the name of each hard-linked file as
1563: though it had been changed; it now outputs a "is hard linked" message for
1564: the file. (2) With -i it would output all dots for the unchanged
1565: attributes of a hard-link; it now changes those dots to spaces, as is
1566: done for other totally unchanged items.
1567:
1568: - When backing up a changed symlink or device, get rid of any old backup
1569: item so that we don't get an "already exists" error.
1570:
1571: - A couple places that were comparing a local and a remote modification-
1572: time were not honoring the --modify-window option.
1573:
1574: - Fixed a bug where the 'p' (permissions) itemized-changes flag might get
1575: set too often (if some non-significant mode bits differed).
1576:
1577: - Fixed a really old, minor bug that could cause rsync to warn about being
1578: unable to mkdir() a path that ends in "/." because it just created the
1579: directory (required --relative, --no-implied-dirs, a source path that
1580: ended in either a trailing slash or a trailing "/.", and a non-existing
1581: destination dir to tickle the bug in a recent version).
1582:
1583: ENHANCEMENTS:
1584:
1585: - Made the "max verbosity" setting in the rsyncd.conf file settable on a
1586: per-module basis (which now matches the documentation).
1587:
1588: - The support/rrsync script has been upgraded to verify the args of options
1589: that take args (instead of rejecting any such options). The script was
1590: also changed to try to be more secure and to fix a problem in the parsing
1591: of a pull operation that has multiple sources.
1592:
1593: - Improved the documentation that explains the difference between a
1594: normal daemon transfer and a daemon-over remote-shell transfer.
1595:
1596: - Some of the diffs supplied in the patches dir were fixed and/or
1597: improved.
1598:
1599: BUILD CHANGES:
1600:
1601: - Made configure define NOBODY_USER (currently hard-wired to "nobody") and
1602: NOBODY_GROUP (set to either "nobody" or "nogroup" depending on what we
1603: find in the /etc/group file).
1604:
1605: - Added a test to the test suite, itemized.test, that tests the output of
1606: -i (log-format w/%i) and some double-verbose messages.
1607:
1608:
1609: NEWS for rsync 2.6.5 (1 Jun 2005)
1610: Protocol: 29 (unchanged)
1611: Changes since 2.6.4:
1612:
1613: OUTPUT CHANGES:
1614:
1615: - Non-printable chars in filenames are now output using backslash-
1616: escaped characters rather than '?'s. Any non-printable character is
1617: output using 3 digits of octal (e.g. "\n" -> "\012"), and a backslash
1618: is now output as "\\". Rsync also uses your locale setting, which
1619: can make it treat fewer high-bit characters as non-printable.
1620:
1621: - If rsync received an empty file-list when pulling files, it would
1622: output a "nothing to do" message and exit with a 0 (success) exit
1623: status, even if the remote rsync returned an error (it did not do
1624: this under the same conditions when pushing files). This was changed
1625: to make the pulling behavior the same as the pushing behavior: we
1626: now do the normal end-of-run outputting (depending on options) and
1627: exit with the appropriate exit status.
1628:
1629: BUG FIXES:
1630:
1631: - A crash bug was fixed when a daemon had its "path" set to "/", did
1632: not have chroot enabled, and used some anchored excludes in the
1633: rsyncd.conf file.
1634:
1635: - Fixed a bug in the transfer of a single file when -H is specified
1636: (rsync would either infinite loop or perhaps crash).
1637:
1638: - Fixed a case where the generator might try (and fail) to tweak the
1639: write-permissions of a read-only directory in list-only mode (this
1640: only caused an annoying warning message).
1641:
1642: - If --compare-dest or --link-dest uses a locally-copied file as the
1643: basis for an updated version, log this better when --verbose or -i
1644: is in effect.
1645:
1646: - Fixed the accidental disabling of --backup during the --delete-after
1647: processing.
1648:
1649: - Restored the ability to use the --address option in client mode (in
1650: addition to its use in daemon mode).
1651:
1652: - Make sure that some temporary progress information from the delete
1653: processing does not get left on the screen when it is followed by a
1654: newline.
1655:
1656: - When --existing skips a directory with extra verbosity, refer to it
1657: as a "directory", not a "file".
1658:
1659: - When transferring a single file to a different-named file, any
1660: generator messages that are source-file related no longer refer to
1661: the file by the destination filename.
1662:
1663: - Fixed a bug where hard-linking a group of files might fail if the
1664: generator hasn't created a needed destination directory yet.
1665:
1666: - Fixed a bug where a hard-linked group of files that is newly-linked
1667: to a file in a --link-dest dir doesn't link the files from the rest
1668: of the cluster.
1669:
1670: - When deleting files with the --one-file-system (-x) option set, rsync
1671: no longer tries to remove files from inside a mount-point on the
1672: receiving side. Also, we don't complain about being unable to remove
1673: the mount-point dir.
1674:
1675: - Fixed a compatibility problem when using --cvs-ignore (-C) and
1676: sending files to an older rsync without using --delete.
1677:
1678: - Make sure that a "- !" or "+ !" include/exclude pattern does not
1679: trigger the list-clearing action that is reserved for "!".
1680:
1681: - Avoid a timeout in the generator when the sender/receiver aren't
1682: handling the generator's checksum output quickly enough.
1683:
1684: - Fixed the omission of some directories in the delete processing when
1685: --relative (-R) was combined with a source path that had a trailing
1686: slash.
1687:
1688: - Fixed a case where rsync would erroneously delete some files and then
1689: re-transfer them when the options --relative (-R) and --recursive
1690: (-r) were both enabled (along with --delete) and a source path had a
1691: trailing slash.
1692:
1693: - Make sure that --max-size doesn't affect a device or a symlink.
1694:
1695: - Make sure that a system with a really small MAXPATHLEN does not cause
1696: the buffers in readfd_unbuffered() to be too small to receive normal
1697: messages. (This mainly affected Cygwin.)
1698:
1699: - If a source pathname ends with a filename of "..", treat it as if
1700: "../" had been specified (so that we don't copy files to the parent
1701: dir of the destination).
1702:
1703: - If --delete is combined with a file-listing rsync command (i.e. no
1704: transfer is happening), avoid outputting a warning that we couldn't
1705: delete anything.
1706:
1707: - If --stats is specified with --delete-after, ensure that all the
1708: "deleting" messages are output before the statistics.
1709:
1710: - Improved one "if" in the deletion code that was only checking errno
1711: for ENOTEMPTY when it should have also been checking for EEXIST (for
1712: compatibility with OS variations).
1713:
1714: ENHANCEMENTS:
1715:
1716: - Added the --only-write-batch=FILE option that may be used (instead
1717: of --write-batch=FILE) to create a batch file without doing any
1718: actual updating of the destination. This allows you to divert all
1719: the file-updating data away from a slow data link (as long as you
1720: are pushing the data to the remote server when creating the batch).
1721:
1722: - When the generator is taking a long time to fill up its output buffer
1723: (e.g. if the transferred files are few, small, or missing), it now
1724: periodically flushes the output buffer so that the sender/receiver
1725: can get started on the files sooner rather than later.
1726:
1727: - Improved the keep-alive code to handle a long silence between the
1728: sender and the receiver that can occur when the sender is receiving
1729: the checksum data for a large file.
1730:
1731: - Improved the auth-errors that are logged by the daemon to include
1732: some information on why the authorization failed: wrong user,
1733: password mismatch, etc. (The client-visible message is unchanged!)
1734:
1735: - Improved the client's handling of an "@ERROR" from a daemon so that
1736: it does not complain about an unexpectedly closed socket (since we
1737: really did expect the socket to close).
1738:
1739: - If the daemon can't open the log-file specified in rsyncd.conf, fall
1740: back to using syslog and log an appropriate warning. This is better
1741: than what was typically a totally silent (and fatal) failure (since a
1742: daemon is not usually run with the --no-detach option that was
1743: necessary to see the error on stderr).
1744:
1745: - The man pages now consistently refer to an rsync daemon as a "daemon"
1746: instead of a "server" (to distinguish it from the server process in a
1747: non-daemon transfer).
1748:
1749: - Made a small change to the rrsync script (restricted rsync -- in the
1750: support dir) to make a read-only server reject all --remove-* options
1751: when sending files (to future-proof it against the possibility of
1752: other similar options being added at some point).
1753:
1754: INTERNAL:
1755:
1756: - Rsync now calls setlocale(LC_CTYPE, ""). This enables isprint() to
1757: better discern which filename characters need to be escaped in
1758: messages (which should result in fewer escaped characters in some
1759: locales).
1760:
1761: - Improved the naming of the log-file open/reopen/close functions.
1762:
1763: - Removed some protocol-compatibility code that was only needed to help
1764: someone running a pre-release of 2.6.4.
1765:
1766: BUILD CHANGES:
1767:
1768: - Added configure option "--disable-locale" to disable any use of
1769: setlocale() in the binary.
1770:
1771: - Fixed a bug in the SUPPORT{,_HARD}_LINKS #defines which prevented
1772: rsync from being built without symlink or hard-link support.
1773:
1774: - Only #define HAVE_REMSH if it is going to be set to 1.
1775:
1776: - Configure now disables the use of mkstemp() under HP-UX (since they
1777: refuse to fix its broken handling of large files).
1778:
1779: - Configure now explicitly checks for the lseek64() function so that
1780: the code can use HAVE_LSEEK64 instead of inferring lseek64()'s
1781: presence based on the presence of the off64_t type.
1782:
1783: - Configure no longer mentions the change in the default remote-shell
1784: (from rsh to ssh) that occurred for the 2.6.0 release.
1785:
1786: - Some minor enhancements to the test scripts.
1787:
1788: - Added a few new *.diff files to the patches dir, including a patch
1789: that enables the optional copying of extended attributes.
1790:
1791:
1792: NEWS for rsync 2.6.4 (30 March 2005)
1793: Protocol: 29 (changed)
1794: Changes since 2.6.3:
1795:
1796: OUTPUT CHANGES:
1797:
1798: - When rsync deletes a directory and outputs a verbose message about
1799: it, it now appends a trailing slash to the name instead of (only
1800: sometimes) outputting a preceding "directory " string.
1801:
1802: - The --stats output will contain file-list time-statistics if both
1803: sides are 2.6.4, or if the local side is 2.6.4 and the files are
1804: being pushed (since the stats come from the sending side).
1805: (Requires protocol 29 for a pull.)
1806:
1807: - The "%o" (operation) log-format escape now has a third value (besides
1808: "send" and "recv"): "del." (with trailing dot to make it 4 chars).
1809: This changes the way deletions are logged in the daemon's log file.
1810:
1811: - When the --log-format option is combined with --verbose, rsync now
1812: avoids outputting the name of the file twice in most circumstances.
1813: As long as the --log-format item does not refer to any post-transfer
1814: items (such as %b or %c), the --log-format message is output prior to
1815: the transfer, so --verbose is now the equivalent of a --log-format of
1816: '%n%L' (which outputs the name and any link info). If the log output
1817: must occur after the transfer to be complete, the only time the name
1818: is also output prior to the transfer is when --progress was specified
1819: (so that the name will precede the progress stats, and the full
1820: --log-format output will come after).
1821:
1822: - Non-printable characters in filenames are replaced with a '?' to
1823: avoid corrupting the screen or generating empty lines in the output.
1824:
1825: BUG FIXES:
1826:
1827: - Restore the list-clearing behavior of "!" in a .cvsignore file (2.6.3
1828: was only treating it as a special token in an rsync include/exclude
1829: file).
1830:
1831: - The combination of --verbose and --dry-run now mentions the full list
1832: of changes that would be output without --dry-run.
1833:
1834: - Avoid a mkdir warning when removing a directory in the destination
1835: that already exists in the --backup-dir.
1836:
1837: - An OS that has a binary mode for its files (such as cygwin) needed
1838: setmode(fd, O_BINARY) called on the temp-file we opened with
1839: mkstemp(). (Fix derived from cygwin's 2.6.3 rsync package.)
1840:
1841: - Fixed a potential hang when verbosity is high, the client side is
1842: the sender, and the file-list is large.
1843:
1844: - Fixed a potential protocol-corrupting bug where the generator could
1845: merge a message from the receiver into the middle of a multiplexed
1846: packet of data if only part of that data had been written out to the
1847: socket when the message from the generator arrived.
1848:
1849: - We now check if the OS doesn't support using mknod() for creating
1850: FIFOs and sockets, and compile-in some compatibility code using
1851: mkfifo() and socket() when necessary.
1852:
1853: - Fixed an off-by-one error in the handling of --max-delete=N. Also,
1854: if the --max-delete limit is exceeded during a run, we now output a
1855: warning about this at the end of the run and exit with a new error
1856: code (25).
1857:
1858: - One place in the code wasn't checking if fork() failed.
1859:
1860: - The "ignore nonreadable" daemon parameter used to erroneously affect
1861: readable symlinks that pointed to a non-existent file.
1862:
1863: - If the OS does not have lchown() and a chown() of a symlink will
1864: affect the referent of a symlink (as it should), we no longer try
1865: to set the user and group of a symlink.
1866:
1867: - The generator now properly runs the hard-link loop and the dir-time
1868: rewriting loop after we're sure that the redo phase is complete.
1869:
1870: - When --backup was specified with --partial-dir=DIR, where DIR is a
1871: relative path, the backup code was erroneously trying to backup a
1872: file that was put into the partial-dir.
1873:
1874: - If a file gets resent in a single transfer and the --backup option is
1875: enabled along with --inplace, rsync no longer performs a duplicate
1876: backup (it used to overwrite the first backup with the failed file).
1877:
1878: - One call to flush_write_file() was not being checked for an error.
1879:
1880: - The --no-relative option was not being sent from the client to a
1881: server sender.
1882:
1883: - If an rsync daemon specified "dont compress = ..." for a file and the
1884: client tried to specify --compress, the libz code was not handling a
1885: compression level of 0 properly. This could cause a transfer failure
1886: if the block-size for a file was large enough (e.g. rsync might have
1887: exited with an error for large files).
1888:
1889: - Fixed a bug that would sometimes surface when using --compress and
1890: sending a file with a block-size larger than 64K (either manually
1891: specified, or computed due to the file being really large). Prior
1892: versions of rsync would sometimes fail to decompress the data
1893: properly, and thus the transferred file would fail its verification.
1894:
1895: - If a daemon can't open the specified log file (i.e. syslog is not
1896: being used), die without crashing. We also output an error about
1897: the failure on stderr (which will only be seen if --no-detach was
1898: specified) and exit with a new error code (6).
1899:
1900: - A local transfer no longer duplicates all its include/exclude options
1901: (since the forked process already has a copy of the exclude list,
1902: there's no need to send them a set of duplicates).
1903:
1904: - The output of the items that are being updated by the generator (dirs,
1905: symlinks, devices) is now intermingled in the proper order with the
1906: output from the items that the receiver is updating (regular files)
1907: when pulling. This misordering was particularly bad when --progress
1908: was specified. (Requires protocol 29.)
1909:
1910: - When --timeout is specified, lulls that occur in the transfer while
1911: the generator is doing work that does not generate socket traffic
1912: (looking for changed files, deleting files, doing directory-time
1913: touch-ups, etc.) will cause a new keep-alive packet to be sent that
1914: should keep the transfer going as long as the generator continues to
1915: make progress. (Requires protocol 29.)
1916:
1917: - The stat size of a device is not added to the total file size of the
1918: items in the transfer (the size might be undefined on some OSes).
1919:
1920: - Fixed a problem with refused-option messages sometimes not making it
1921: back to the client side when a remote --files-from was in effect and
1922: the daemon was the receiver.
1923:
1924: - The --compare-dest option was not updating a file that differed in
1925: (the preserved) attributes from the version in the compare-dest DIR.
1926:
1927: - When rsync is copying files into a write-protected directory, fixed
1928: the change-report output for the directory so that we don't report
1929: an identical directory as changed.
1930:
1931: ENHANCEMENTS:
1932:
1933: - Rsync now supports popt's option aliases, which means that you can
1934: use /etc/popt and/or ~/.popt to create your own option aliases.
1935:
1936: - Added the --delete-during (--del) option which will delete files
1937: from the receiving side incrementally as each directory in the
1938: transfer is being processed. This makes it more efficient than the
1939: default, before-the-transfer behavior, which is now also available as
1940: --delete-before (and is still the default --delete-WHEN option that
1941: will be chosen if --delete or --delete-excluded is specified without
1942: a --delete-WHEN choice). All the --del* options infer --delete, so
1943: an rsync daemon that refuses "delete" will still refuse to allow any
1944: file-deleting options (including the new --remove-sent-files option).
1945:
1946: - All the --delete-WHEN options are now more memory efficient:
1947: Previously an duplicate set of file-list objects was created on the
1948: receiving side for the entire destination hierarchy. The new
1949: algorithm only creates one directory of objects at a time (for files
1950: inside the transfer).
1951:
1952: - Added the --copy-dest option, which works like --link-dest except
1953: that it locally copies identical files instead of hard-linking them.
1954:
1955: - Added support for specifying multiple --compare-dest, --copy-dest, or
1956: --link-dest options, but only of a single type. (Promoted from the
1957: patches dir and enhanced.) (Requires protocol 29.)
1958:
1959: - Added the --max-size option. (Promoted from the patches dir.)
1960:
1961: - The daemon-mode options are now separated from the normal rsync
1962: options so that they can't be mixed together. This makes it
1963: impossible to start a daemon that has improper default option values
1964: (which could cause problems when a client connects, such as hanging
1965: or crashing).
1966:
1967: - The --bwlimit option may now be used in combination with --daemon
1968: to specify both a default value for the daemon side and a value
1969: that cannot be exceeded by a user-specified --bwlimit option.
1970:
1971: - Added the "port" parameter to the rsyncd.conf file. (Promoted from
1972: the patches dir.) Also added "address". The command-line options
1973: take precedence over a config-file option, as expected.
1974:
1975: - In _exit_cleanup(): when we are exiting with a partially-received
1976: file, we now flush any data in the write-cache before closing the
1977: partial file.
1978:
1979: - The --inplace support was enhanced to work with --compare-dest,
1980: --link-dest, and (the new) --copy-dest options. (Requires protocol
1981: 29.)
1982:
1983: - Added the --dirs (-d) option for an easier way to copy directories
1984: without recursion. Any directories that are encountered are created
1985: on the destination. Specifying a directory with a trailing slash
1986: copies its immediate contents to the destination.
1987:
1988: - The --files-from option now implies --dirs (-d).
1989:
1990: - Added the --list-only option, which is mainly a way for the client to
1991: put the server into listing mode without needing to resort to any
1992: internal option kluges (e.g. the age-old use of "-r --exclude="/*/*"
1993: for a non-recursive listing). This option is used automatically
1994: (behind the scenes) when a modern rsync speaks to a modern daemon,
1995: but may also be specified manually if you want to force the use of
1996: the --list-only option over a remote-shell connection.
1997:
1998: - Added the --omit-dir-times (-O) option, which will avoid updating
1999: the modified time for directories when --times was specified. This
2000: option will avoid an extra pass through the file-list at the end of
2001: the transfer (to tweak all the directory times), which may provide
2002: an appreciable speedup for a really large transfer. (Promoted from
2003: the patches dir.)
2004:
2005: - Added the --filter (-f) option and its helper option, -F. Filter
2006: rules are an extension to the existing include/exclude handling
2007: that also supports nested filter files as well as per-directory
2008: filter files (like .cvsignore, but with full filter-rule parsing).
2009: This new option was chosen in order to ensure that all existing
2010: include/exclude processing remained 100% compatible with older
2011: versions. Protocol 29 is needed for full filter-rule support, but
2012: backward-compatible rules work with earlier protocol versions.
2013: (Promoted from the patches dir and enhanced.)
2014:
2015: - Added the --delay-updates option that puts all updated files into
2016: a temporary directory (by default ".~tmp~", but settable via the
2017: --partial-dir=DIR option) until the end of the transfer. This
2018: makes the updates a little more atomic for a large transfer.
2019:
2020: - If rsync is put into the background, any output from --progress is
2021: reduced.
2022:
2023: - Documented the "max verbosity" setting for rsyncd.conf. (This
2024: setting was added a couple releases ago, but left undocumented.)
2025:
2026: - The sender and the generator now double-check the file-list index
2027: they are given, and refuse to try to do a file transfer on a
2028: non-file index (since that would indicate that something had gone
2029: very wrong).
2030:
2031: - Added the --itemize-changes (-i) option, which is a way to output a
2032: more detailed list of what files changed and in what way. The effect
2033: is the same as specifying a --log-format of "%i %n%L" (see both the
2034: rsync and rsyncd.conf manpages). Works with --dry-run too.
2035:
2036: - Added the --fuzzy (-y) option, which attempts to find a basis file
2037: for a file that is being created from scratch. The current algorithm
2038: only looks in the destination directory for the created file, but it
2039: does attempt to find a match based on size/mod-time (in case the file
2040: was renamed with no other changes) as well as based on a fuzzy
2041: name-matching algorithm. This option requires protocol 29 because it
2042: needs the new file-sorting order. (Promoted from patches dir and
2043: enhanced.) (Requires protocol 29.)
2044:
2045: - Added the --remove-sent-files option, which lets you move files
2046: between systems.
2047:
2048: - The hostname in HOST:PATH or HOST::PATH may now be an IPv6 literal
2049: enclosed in '[' and ']' (e.g. "[::1]"). (We already allowed IPv6
2050: literals in the rsync://HOST:PORT/PATH format.)
2051:
2052: - When rsync recurses to build the file list, it no longer keeps open
2053: one or more directory handles from the dir's parent dirs.
2054:
2055: - When building under windows, the default for --daemon is now to
2056: avoid detaching, requiring the new --detach option to force rsync
2057: to detach.
2058:
2059: - The --dry-run option can now be combined with either --write-batch or
2060: --read-batch, allowing you to run a do-nothing test command to see
2061: what would happen without --dry-run.
2062:
2063: - The daemon's "read only" config item now sets an internal read_only
2064: variable that makes extra sure that no write/delete calls on the
2065: read-only side can succeed.
2066:
2067: - The log-format % escapes can now have a numeric field width in
2068: between the % and the escape letter (e.g. "%-40n %08p").
2069:
2070: - Improved the option descriptions in the --help text.
2071:
2072: SUPPORT FILES:
2073:
2074: - Added atomic-rsync to the support dir: a perl script that will
2075: transfer some files using rsync, and then move the updated files into
2076: place all at once at the end of the transfer. Only works when
2077: pulling, and uses --link-dest and a parallel hierarchy of files to
2078: effect its update.
2079:
2080: - Added mnt-excl to the support dir: a perl script that takes the
2081: /proc/mounts file and translates it into a set of excludes that will
2082: exclude all mount points (even mapped mounts to the same disk). The
2083: excludes are made relative to the specified source dir and properly
2084: anchored.
2085:
2086: - Added savetransfer.c to the support dir: a C program that can make
2087: a copy of all the data that flows over the wire. This lets you test
2088: for data corruption (by saving the data on both the sending side and
2089: the receiving side) and provides one way to debug a protocol error.
2090:
2091: - Added rrsync to the support dir: this is an updated version of Joe
2092: Smith's restricted rsync perl script. This helps to ensure that only
2093: certain rsync commands can be run by an ssh invocation.
2094:
2095: INTERNAL:
2096:
2097: - Added better checking of the checksum-header values that come over
2098: the socket.
2099:
2100: - Merged a variety of file-deleting functions into a single function so
2101: that it is easier to maintain.
2102:
2103: - Improved the type of some variables (particularly blocksize vars) for
2104: consistency and proper size.
2105:
2106: - Got rid of the uint64 type (which we didn't need).
2107:
2108: - Use a slightly more compatible set of core #include directives.
2109:
2110: - Defined int32 in a way that ensures that the build dies if we can't
2111: find a variable with at least 32 bits.
2112:
2113: PROTOCOL DIFFERENCES FOR VERSION 29:
2114:
2115: - A 16-bit flag-word is transmitted after every file-list index. This
2116: indicates what is changing between the sender and the receiver. The
2117: generator now transmits an index and a flag-word to indicate when
2118: dirs and symlinks have changed (instead of producing a message),
2119: which makes the outputting of the information more consistent and
2120: less prone to screen corruption (because the local receiver/sender is
2121: now outputting all the file-change info messages).
2122:
2123: - If a file is being hard-linked, the ITEM_XNAME_FOLLOWS bit is enabled
2124: in the flag-word and the name of the file that was linked immediately
2125: follows in vstring format (see below).
2126:
2127: - If a file is being transferred with an alternate-basis file, the
2128: ITEM_BASIS_TYPE_FOLLOWS bit is enabled in the flag-word and a single
2129: byte follows, indicating what type of basis file was chosen. If that
2130: indicates that a fuzzy-match was selected, the ITEM_XNAME_FOLLOWS bit
2131: is set in the flag-word and the name of the match in vstring format
2132: follows the basis byte. A vstring is a variable length string that
2133: has its size written prior to the string, and no terminating null.
2134: If the string is from 1-127 bytes, the length is a single byte. If
2135: it is from 128-32767 bytes, the length is written as ((len >> 8) |
2136: 0x80) followed by (len % 0x100).
2137:
2138: - The sending of exclude names is done using filter-rule syntax. This
2139: means that all names have a prefixed rule indicator, even excludes
2140: (which used to be sent as a bare pattern, when possible). The -C
2141: option will include the per-dir .cvsignore merge file in the list of
2142: filter rules so it is positioned correctly (unlike in some older
2143: transfer scenarios).
2144:
2145: - Rsync sorts the filename list in a different way: it sorts the subdir
2146: names after the non-subdir names for each dir's contents, and it
2147: always puts a dir's contents immediately after the dir's name in the
2148: list. (Previously an item named "foo.txt" would sort in between
2149: directory "foo/" and "foo/bar".)
2150:
2151: - When talking to a protocol 29 rsync daemon, a list-only request
2152: is able to note this before the options are sent over the wire and
2153: the new --list-only option is included in the options.
2154:
2155: - When the --stats bytes are sent over the wire (or stored in a batch),
2156: they now include two elapsed-time values: one for how long it took to
2157: build the file-list, and one for how long it took to send it over the
2158: wire (each expressed in thousandths of a second).
2159:
2160: - When --delete-excluded is specified with some filter rules (AKA
2161: excludes), a client sender will now initiate a send of the rules to
2162: the receiver (older protocols used to omit the sending of excludes in
2163: this situation since there were no receiver-specific rules that
2164: survived --delete-excluded back then). Note that, as with all the
2165: filter-list sending, only items that are significant to the other
2166: side will actually be sent over the wire, so the filter-rule list
2167: that is sent in this scenario is often empty.
2168:
2169: - An index equal to the file-list count is sent as a keep-alive packet
2170: from the generator to the sender, which then forwards it on to the
2171: receiver. This normally invalid index is only a valid keep-alive
2172: packet if the 16-bit flag-word that follows it contains a single bit
2173: (ITEM_IS_NEW, which is normally an illegal flag to appear alone).
2174:
2175: - A protocol-29 batch file includes a bit for the setting of the --dirs
2176: option and for the setting of the --compress option. Also, the shell
2177: script created by --write-batch will use the --filter option instead
2178: of --exclude-from to capture any filter rules.
2179:
2180: BUILD CHANGES:
2181:
2182: - Handle an operating system that use mkdev() in place of makedev().
2183:
2184: - Improved configure to better handle cross-compiling.
2185:
2186:
2187: NEWS for rsync 2.6.3 (30 Sep 2004)
2188: Protocol: 28 (unchanged)
2189: Changes since 2.6.2:
2190:
2191: SECURITY FIXES:
2192:
2193: - A bug in the sanitize_path routine (which affects a non-chrooted
2194: rsync daemon) could allow a user to craft a pathname that would get
2195: transformed into an absolute path for certain options (but not for
2196: file-transfer names). If you're running an rsync daemon with chroot
2197: disabled, *please upgrade*, ESPECIALLY if the user privs you run
2198: rsync under is anything above "nobody".
2199:
2200: OUTPUT CHANGES (ATTN: those using a script to parse the verbose output):
2201:
2202: - Please note that the 2-line footer (output when verbose) now uses the
2203: term "sent" instead of "wrote" and "received" instead of "read". If
2204: you are not parsing the numeric values out of this footer, a script
2205: would be better off using the empty line prior to the footer as the
2206: indicator that the verbose output is over.
2207:
2208: - The output from the --stats option was similarly affected to change
2209: "written" to "sent" and "read" to "received".
2210:
2211: - Rsync ensures that a filename that contains a newline gets mentioned
2212: with each newline transformed into a question mark (which prevents a
2213: filename from causing an empty line to be output).
2214:
2215: - The "backed up ..." message that is output when at least 2 --verbose
2216: options are specified is now the same both with and without the
2217: --backup-dir option.
2218:
2219: BUG FIXES:
2220:
2221: - Fixed a crash bug that might appear when --delete was used and
2222: multiple source directories were specified.
2223:
2224: - Fixed a 32-bit truncation of the file length when generating the
2225: checksums.
2226:
2227: - The --backup code no longer attempts to create some directories
2228: over and over again (generating warnings along the way).
2229:
2230: - Fixed a bug in the reading of the secrets file (by the daemon) and
2231: the password file (by the client): the files no longer need to be
2232: terminated by a newline for their content to be read in.
2233:
2234: - If a file has a read error on the sending side or the reconstructed
2235: data doesn't match the expected checksum (perhaps due to the basis
2236: file changing during the transfer), the receiver will no longer
2237: retain the resulting file unless the --partial option was specified.
2238: (Note: for the read-error detection to work, neither side can be
2239: older than 2.6.3 -- older receivers will always retain the file, and
2240: older senders don't tell the receiver that the file had a read
2241: error.)
2242:
2243: - If a file gets resent in a single transfer and the --backup option
2244: is enabled, rsync no longer performs a duplicate backup (it used to
2245: overwrite the original file in the backup area).
2246:
2247: - Files specified in the daemon's "exclude" or "exclude from" config
2248: items are now excluded from being uploaded (assuming that the module
2249: allows uploading at all) in addition to the old download exclusion.
2250:
2251: - Got rid of a potential hang in the receiver when near the end of a
2252: phase.
2253:
2254: - When using --backup without a --backup-dir, rsync no longer preserves
2255: the modify time on directories. This avoids confusing NFS.
2256:
2257: - When --copy-links (-L) is specified, we now output a separate error
2258: for a symlink that has no referent instead of claiming that a file
2259: "vanished".
2260:
2261: - The --copy-links (-L) option no longer has the side-effect of telling
2262: the receiving side to follow symlinks. See the --keep-dirlinks
2263: option (mentioned below) for a way to specify that behavior.
2264:
2265: - Error messages from the daemon server's option-parsing (such as
2266: refused options) are now successfully transferred back to the client
2267: (the server used to fail to send the message because the socket
2268: wasn't in the right state for the message to get through).
2269:
2270: - Most transfer errors that occur during a daemon transfer are now
2271: returned to the user in addition to being logged (some messages are
2272: intended to be daemon-only and are not affected by this).
2273:
2274: - Fixed a bug in the daemon authentication code when using one of the
2275: batch-processing options.
2276:
2277: - We try to work around some buggy IPv6 implementations that fail to
2278: implement IPV6_V6ONLY. This should fix the "address in use" error
2279: that some daemons get when running on an OS with a buggy IPv6
2280: implementation. Also, if the new code gets this error, we might
2281: suggest that the user specify --ipv4 or --ipv6 (if we think it will
2282: help).
2283:
2284: - When the remote rsync dies, make a better effort to recover any error
2285: messages it may have sent before dying (the local rsync used to just
2286: die with a socket-write error).
2287:
2288: - When using --delete and a --backup-dir that contains files that are
2289: hard-linked to their destination equivalents, rsync now makes sure
2290: that removed files really get removed (avoids a really weird rename()
2291: behavior).
2292:
2293: - Avoid a bogus run-time complaint about a lack of 64-bit integers when
2294: the int64 type is defined as an off_t and it actually has 64-bits.
2295:
2296: - Added a configure check for open64() without mkstemp64() so that we
2297: can avoid using mkstemp() when such a combination is encountered.
2298: This bypasses a problem writing out large temp files on OSes such as
2299: AIX and HP-UX.
2300:
2301: - Fixed an age-old crash problem with --read-batch on a local copy
2302: (rsync was improperly assuming --whole-file for the local copy).
2303:
2304: - When --dry-run (-n) is used and the destination directory does not
2305: exist, rsync now produces a correct report of files that would be
2306: sent instead of dying with a chdir() error.
2307:
2308: - Fixed a bug that could cause a slow-to-connect rsync daemon to die
2309: with an error instead of waiting for the connection to finish.
2310:
2311: - Fixed an ssh interaction that could cause output to be lost when the
2312: user chose to combine the output of rsync's stdout and stderr (e.g.
2313: using the "2>&1").
2314:
2315: - Fixed an option-parsing bug when --files-from got passed to a daemon.
2316:
2317: ENHANCEMENTS:
2318:
2319: - Added the --partial-dir=DIR option that lets you specify where to
2320: (temporarily) put a partially transferred file (instead of over-
2321: writing the destination file). E.g. --partial-dir=.rsync-partial
2322: Also added support for the RSYNC_PARTIAL_DIR environment variable
2323: that, when found, transforms a regular --partial option (such as
2324: the convenient -P option) into one that also specifies a directory.
2325:
2326: - Added --keep-dirlinks (-K), which allows you to symlink a directory
2327: onto another partition on the receiving side and have rsync treat it
2328: as matching a normal directory from the sender.
2329:
2330: - Added the --inplace option that tells rsync to write each destination
2331: file without using a temporary file. The matching of existing data
2332: in the destination file can be severely limited by this, but there
2333: are also cases where this is more efficient (such as appending data).
2334: Use only when needed (see the man page for more details).
2335:
2336: - Added the "write only" option for the daemon's config file.
2337:
2338: - Added long-option names for -4 and -6 (namely --ipv4 and --ipv6)
2339: and documented all these options in the man page.
2340:
2341: - Improved the handling of the --bwlimit option so that it's less
2342: bursty, more accurate, and works properly over a larger range of
2343: values.
2344:
2345: - The rsync daemon-over-ssh code now looks for SSH_CONNECTION and
2346: SSH2_CLIENT in addition to SSH_CLIENT to figure out the IP address.
2347:
2348: - Added the --checksum-seed=N option for advanced users.
2349:
2350: - Batch writing/reading has a brand-new implementation that is simpler,
2351: fixes a few weird problems with the old code (such as no longer
2352: sprinkling the batch files into different dirs or even onto different
2353: systems), and is much less intrusive into the code (making it easier
2354: to maintain for the future). The new code generates just one data
2355: file instead of three, which makes it possible to read the batch on
2356: stdin via a remote shell. Also, the old requirement of forcing the
2357: same fixed checksum-seed for all batch processing has been removed.
2358:
2359: - If an rsync daemon has a module set with "list = no" (which hides its
2360: presence in the list of available modules), a user that fails to
2361: authenticate gets the same "unknown module" error that they would get
2362: if the module were actually unknown (while still logging the real
2363: error to the daemon's log file). This prevents fishing for module
2364: names.
2365:
2366: - The daemon's "refuse options" config item now allows you to match
2367: option names using wildcards and/or the single-letter option names.
2368:
2369: - Each transferred file now gets its permissions and modified-time
2370: updated before the temp-file gets moved into place. Previously, the
2371: finished file would have a very brief window where its permissions
2372: disallowed all group and world access.
2373:
2374: - Added the ability to parse a literal IPv6 address in an "rsync:" URL
2375: (e.g. rsync://[2001:638:500:101::21]:873/module/dir).
2376:
2377: - The daemon's wildcard expanding code can now handle more than 1000
2378: filenames (it's now limited by memory instead of having a hard-wired
2379: limit).
2380:
2381: INTERNAL:
2382:
2383: - Some cleanup in the exclude code has saved some per-exclude memory
2384: and made the code easier to maintain.
2385:
2386: - Improved the argv-overflow checking for a remote command that has a
2387: lot of args.
2388:
2389: - Use rsyserr() in the various places that were still calling rprintf()
2390: with strerror() as an arg.
2391:
2392: - If an rsync daemon is listening on multiple sockets (to handle both
2393: IPv4 and IPv6 to a single port), we now close all the unneeded file
2394: handles after we accept a connection (we used to close just one of
2395: them).
2396:
2397: - Optimized the handling of larger block sizes (rsync used to slow to a
2398: crawl if the block size got too large).
2399:
2400: - Optimized away a loop in hash_search().
2401:
2402: - Some improvements to the sanitize_path() and clean_fname() functions
2403: makes them more efficient and produce better results (while still
2404: being compatible with the file-name cleaning that gets done on both
2405: sides when sending the file-list).
2406:
2407: - Got rid of alloc_sanitize_path() after adding a destination-buffer
2408: arg to sanitize_path() made it possible to put all the former's
2409: functionality into the latter.
2410:
2411: - The file-list that is output when at least 4 verbose options are
2412: specified reports the uid value on the sender even when rsync is
2413: not running as root (since we might be sending to a root receiver).
2414:
2415: BUILD CHANGES:
2416:
2417: - Added a "gen" target to rebuild most of the generated files,
2418: including configure, config.h.in, the man pages, and proto.h.
2419:
2420: - If "make proto" doesn't find some changes in the prototypes, the
2421: proto.h file is left untouched (its time-stamp used to always be
2422: updated).
2423:
2424: - The variable $STRIP (that is optionally set by the install-strip
2425: target's rule) was changed to $INSTALL_STRIP because some systems
2426: have $STRIP already set in the environment.
2427:
2428: - Fixed a build problem when SUPPORT_HARD_LINKS isn't defined.
2429:
2430: - When cross-compiling, the gettimeofday() function is now assumed to
2431: be a modern version that takes two-args (since we can't test it).
2432:
2433: DEVELOPER RELATED:
2434:
2435: - The scripts in the testsuite dir were cleaned up a bit and a few
2436: new tests added.
2437:
2438: - Some new diffs were added to the patches dir, and some accepted
2439: ones were removed.

2442: NEWS for rsync 2.6.2 (30 Apr 2004)
2443: Protocol: 28 (unchanged)
2444: Changes since 2.6.1:
2445:
2446: BUG FIXES:
2447:
2448: - Fixed a major bug in the sorting of the filenames when --relative
2449: is used for some sources (just sources such as "/" and "/*" were
2450: affected). This fix ensures that we ask for the right file-list
2451: item when requesting changes from the sender.
2452:
2453: - Rsync now checks the return value of the close() function to
2454: better report disk-full problems on an NFS file system.
2455:
2456: - Restored the old daemon-server behavior of logging error messages
2457: rather than returning them to the user. (A better long-term fix
2458: will be sought in the future.)
2459:
2460: - An obscure uninitialized-variable bug was fixed in the uid/gid
2461: code. (This bug probably had no ill effects.)
2462:
2463: BUILD CHANGES:
2464:
2465: - Got rid of the configure check for sys/sysctl.h (it wasn't used
2466: and was causing a problem on some systems). Also improved the
2467: broken-largefile-locking test to try to avoid failure due to an
2468: NFS build-dir.
2469:
2470: - Fixed a compile problem on systems that don't define
2471: AI_NUMERICHOST.
2472:
2473: - Fixed a compile problem in the popt source for compilers that
2474: don't support __attribute__.
2475:
2476: DEVELOPER RELATED:
2477:
2478: - Improved the testsuite's "merge" test to work on OSF1.
2479:
2480: - Two new diffs were added to the patches dir.
2481:
2482:
2483: NEWS for rsync 2.6.1 (26 Apr 2004)
2484: Protocol: 28 (changed)
2485: Changes since 2.6.0:
2486:
2487: SECURITY FIXES:
2488:
2489: - Paths sent to an rsync daemon are more thoroughly sanitized when
2490: chroot is not used. If you're running a non-read-only rsync
2491: daemon with chroot disabled, *please upgrade*, ESPECIALLY if the
2492: user privs you run rsync under is anything above "nobody".
2493:
2494: ENHANCEMENTS:
2495:
2496: - Lower memory use, more optimal transfer of data over the socket,
2497: and lower CPU usage (see the INTERNAL section for details).
2498:
2499: - The RSYNC_PROXY environment variable can now contain a
2500: "USER:PASS@" prefix before the "HOST:PORT" information.
2501: (Bardur Arantsson)
2502:
2503: - The --progress output now mentions how far along in the transfer
2504: we are, including both a count of files transferred and a
2505: percentage of the total file-count that we've processed. It also
2506: shows better current-rate-of-transfer and remaining-transfer-time
2507: values.
2508:
2509: - Documentation changes now attempt to describe some often mis-
2510: understood features more clearly.
2511:
2512: BUG FIXES:
2513:
2514: - When -x (--one-file-system) is combined with -L (--copy-links) or
2515: --copy-unsafe-links, no symlinked files are skipped, even if the
2516: referent file is on a different filesystem.
2517:
2518: - The --link-dest code now works properly for a non-root user when
2519: (1) the UIDs of the source and destination differ and -o was
2520: specified, or (2) when the group of the source can't be used on
2521: the destination and -g was specified.
2522:
2523: - Fixed a bug in the handling of -H (hard-links) that might cause
2524: the expanded PATH/NAME value of the current item to get
2525: overwritten (due to an expanded-name caching bug).
2526:
2527: - We now reset the "new data has been sent" flag at the start of
2528: each file we send. This makes sure that an interrupted transfer
2529: with the --partial option set doesn't keep a shorter temp file
2530: than the current basis file when no new data has been transferred
2531: over the wire for that file.
2532:
2533: - Fixed a byte-order problem in --batch-mode on big-endian machines.
2534: (Jay Fenlason)
2535:
2536: - When using --cvs-exclude, the exclude items we get from a
2537: per-directory's .cvsignore file once again only affect that one
2538: directory (not all following directories too). The items are also
2539: now properly word-split and parsed without any +/- prefix parsing.
2540:
2541: - When specifying the USER@HOST: prefix for a file, the USER part
2542: can now contain an '@', if needed (i.e. the last '@' is used to
2543: find the HOST, not the first).
2544:
2545: - Fixed some bugs in the handling of group IDs for non-root users:
2546: (1) It properly handles a group that the sender didn't have a name
2547: for (it would previously skip changing the group on any files in
2548: that group). (2) If --numeric-ids is used, rsync no longer
2549: attempts to set groups that the user doesn't have the permission
2550: to set.
2551:
2552: - Fixed the "refuse options" setting in the rsyncd.conf file.
2553:
2554: - Improved the -x (--one-file-system) flag's handling of any mount-
2555: point directories we encounter. It is both more optimal (in that
2556: it no longer does a useless scan of the contents of the mount-
2557: point dirs) and also fixes a bug where a remapped mount of the
2558: original filesystem could get discovered in a subdir we should be
2559: ignoring.
2560:
2561: - Rsync no longer discards a double-slash at the start of a filename
2562: when trying to open the file. It also no longer constructs names
2563: that start with a double slash (unless the user supplied them).
2564:
2565: - Path-specifying options to a daemon should now work the same with
2566: or without chroot turned on. Previously, such a option (such as
2567: --link-dest) would get its absolute path munged into a relative
2568: one if chroot was not on, making that setting fairly useless.
2569: Rsync now transforms the path into one that is based on the
2570: module's base dir when chroot is not enabled.
2571:
2572: - Fixed a compatibility problem interacting with older rsync
2573: versions that might send us an empty --suffix value without
2574: telling us that --backup-dir was specified.
2575:
2576: - The "hosts allow" option for a daemon-over-remote-shell process
2577: now has improved support for IPv6 addresses and a fix for systems
2578: that have a length field in their socket structs.
2579:
2580: - Fixed the ability to request an empty backup --suffix when sending
2581: files to an rsync daemon.
2582:
2583: - Fixed an option-parsing bug when --files-from was sent to a server
2584: sender.
2585:
2586: INTERNAL:
2587:
2588: - Most of the I/O is now buffered, which results in a pretty large
2589: speedup when running under MS Windows. (Craig Barratt)
2590:
2591: - Optimizations to the name-handling/comparing code have made some
2592: significant reductions in user-CPU time for large file sets.
2593:
2594: - Some cleanup of the variable types make the code more consistent.
2595:
2596: - Reduced memory requirements of hard link preservation.
2597: (J.W. Schultz)
2598:
2599: - Implemented a new algorithm for hard-link handling that speeds up
2600: the code significantly. (J.W. Schultz and Wayne Davison)
2601:
2602: - The --hard-link option now uses the first existing file in the
2603: group of linked files as the basis for the transfer. This
2604: prevents the sub-optimal transfer of a file's data when a new
2605: hardlink is added on the sending side and it sorts alphabetically
2606: earlier in the list than the files that are already present on the
2607: receiving side.
2608:
2609: - Dropped support for protocol versions less than 20 (2.3.0 released
2610: 15 Mar 1999) and activated warnings for protocols less than 25
2611: (2.5.0 released 23 Aug 2001). (Wayne Davison and J.W. Schultz,
2612: severally)
2613:
2614: - More optimal data transmission for --hard-links (protocol 28).
2615:
2616: - More optimal data transmission for --checksum (protocol 28).
2617:
2618: - Less memory is used when --checksum is specified.
2619:
2620: - Less memory is used in the file list (a per-file savings).
2621:
2622: - The generator is now better about not modifying the file list
2623: during the transfer in order to avoid a copy-on-write memory
2624: bifurcation (on systems where fork() uses shared memory).
2625: Previously, rsync's shared memory would slowly become unshared,
2626: resulting in real memory usage nearly doubling on the receiving
2627: side by the end of the transfer. Now, as long as permissions
2628: are being preserved, the shared memory should remain that way
2629: for the entire transfer.
2630:
2631: - Changed hardlink info and file_struct + strings to use allocation
2632: pools. This reduces memory use for large file-sets and permits
2633: freeing memory to the OS. (J.W. Schultz)
2634:
2635: - The 2 pipes used between the receiver and generator processes
2636: (which are forked on the same machine) were reduced to 1 pipe and
2637: the protocol improved so that (1) it is now impossible to have the
2638: "redo" pipe fill up and hang rsync, and (2) trailing messages from
2639: the receiver don't get lost on their way through the generator
2640: over to the sender (which mainly affected hard-link messages and
2641: verbose --stats output).
2642:
2643: - Improved the internal uid/gid code to be more portable and a
2644: little more optimized.
2645:
2646: - The device numbers sent when using --devices are now sent as
2647: separate major/minor values with 32-bit accuracy (protocol 28).
2648: Previously, the copied devices were sent as a single 32-bit
2649: number. This will make inter-operation of 64-bit binaries more
2650: compatible with their 32-bit brethren (with both ends of the
2651: connection are using protocol 28). Note that optimizations in the
2652: binary protocol for sending the device numbers often results in
2653: fewer bytes being used than before, even though more precision is
2654: now available.
2655:
2656: - Some cleanup of the exclude/include structures and its code made
2657: things clearer (internally), simpler, and more efficient.
2658:
2659: - The reading & writing of the file-list in batch-mode is now
2660: handled by the same code that sends & receives the list over the
2661: wire. This makes it much easier to maintain. (Note that the
2662: batch code is still considered to be experimental.)
2663:
2664: BUILD CHANGES:
2665:
2666: - The configure script now accepts --with-rsyncd-conf=PATH to
2667: override the default value of the /etc/rsyncd.conf file.
2668:
2669: - Fixed configure bug when running "./configure --disable-ipv6".
2670:
2671: - Fixed compilation problem on Tru64 Unix (having to do with
2672: sockaddr.sa_len and sockaddr.sin_len).
2673:
2674: DEVELOPER RELATED:
2675:
2676: - Fixed "make test" bug when build dir is not the source dir.
2677:
2678: - Added a couple extra diffs in the "patches" dir, removed the ones
2679: that got applied, and rebuilt the rest.
2680:
2681:
2682: NEWS for rsync 2.6.0 (1 Jan 2004)
2683: Protocol: 27 (changed)
2684: Changes since 2.5.7:
2685:
2686: ENHANCEMENTS:
2687:
2688: * "ssh" is now the default remote shell for rsync. If you want to
2689: change this, configure like this: "./configure --with-rsh=rsh".
2690:
2691: * Added --files-from, --no-relative, --no-implied-dirs, and --from0.
2692: Note that --from0 affects the line-ending character for all the
2693: files read by the --*-from options. (Wayne Davison)
2694:
2695: * Length of csum2 is now per-file starting with protocol version
2696: 27. (J.W. Schultz)
2697:
2698: * Per-file dynamic block size is now sqrt(file length). The
2699: per-file checksum size is determined according to an algorithm
2700: provided by Donovan Baarda which reduces the probability of rsync
2701: algorithm corrupting data and falling back using the whole md4
2702: checksums. (J.W. Schultz, Donovan Baarda)
2703:
2704: * The --stats option no longer includes the (debug) malloc summary
2705: unless the verbose option was specified at least twice.
2706:
2707: * Added a new error/warning code for when files vanish from the
2708: sending side. Made vanished source files not interfere with the
2709: file-deletion pass when --delete-after was specified.
2710:
2711: * Various trailing-info sections are now preceded by a newline.
2712:
2713: BUG FIXES:
2714:
2715: * Fixed several exclude/include matching bugs when using wild-cards.
2716: This has a several user-visible effects, all of which make the
2717: matching more consistent and intuitive. This should hopefully not
2718: cause anyone problems since it makes the matching work more like
2719: what people are expecting. (Wayne Davison)
2720:
2721: - A pattern with a "**" no longer causes a "*" to match slashes.
2722: For example, with "/*/foo/**", "foo" must be 2 levels deep.
2723: [If your string has BOTH "*" and "**" wildcards, changing the
2724: "*" wildcards to "**" will provide the old behavior in all
2725: versions.]
2726:
2727: - "**/foo" now matches at the base of the transfer (like /foo
2728: does). [Use "/**/foo" to get the old behavior in all versions.]
2729:
2730: - A non-anchored wildcard term floats to match beyond the base of
2731: the transfer. E.g. "CVS/R*" matches at the end of the path,
2732: just like the non-wildcard term "CVS/Root" does. [Use "/CVS/R*"
2733: to get the old behavior in all versions.]
2734:
2735: - Including a "**" in the match term causes it to be matched
2736: against the entire path, not just the name portion, even if
2737: there aren't any interior slashes in the term. E.g. "foo**bar"
2738: would exclude "/path/foo-bar" (just like before) as well as
2739: "/foo-path/baz-bar" (unlike before). [Use "foo*bar" to get the
2740: old behavior in all versions.]
2741:
2742: * The exclude list specified in the daemon's config file is now
2743: properly applied to the pulled items no matter how deep the
2744: user's file-args are in the source tree. (Wayne Davison)
2745:
2746: * For protocol version >= 27, mdfour_tail() is called when the
2747: block size (including checksum_seed) is a multiple of 64.
2748: Previously it was not called, giving the wrong MD4 checksum.
2749: (Craig Barratt)
2750:
2751: * For protocol version >= 27, a 64 bit bit counter is used in
2752: mdfour.c as required by the RFC. Previously only a 32 bit bit
2753: counter was used, causing incorrect MD4 file checksums for
2754: file sizes >= 512MB - 4. (Craig Barratt)
2755:
2756: * Fixed a crash bug when interacting with older rsync versions and
2757: multiple files of the same name are destined for the same dir.
2758: (Wayne Davison)
2759:
2760: * Keep tmp names from overflowing MAXPATHLEN.
2761:
2762: * Make --link-dest honor the absence of -p, -o, and -g.
2763:
2764: * Made rsync treat a trailing slash in the destination in a more
2765: consistent manner.
2766:
2767: * Fixed file I/O error detection. (John Van Essen)
2768:
2769: * Fixed bogus "malformed address {hostname}" message in rsyncd log
2770: when checking IP address against hostnames from "hosts allow"
2771: and "hosts deny" parameters in config file.
2772:
2773: * Print heap statistics when verbose >= 2 instead of when >= 1.
2774:
2775: * Fixed a compression (-z) bug when syncing a mostly-matching file
2776: that contains already-compressed data. (Yasuoka Masahiko and
2777: Wayne Davison)
2778:
2779: * Fixed a bug in the --backup code that could cause deleted files
2780: to not get backed up.
2781:
2782: * When the backup code makes new directories, create them with mode
2783: 0700 instead of 0755 (since the directory permissions in the
2784: backup tree are not yet copied from the main tree).
2785:
2786: * Call setgroups() in a more portable manner.
2787:
2788: * Improved file-related error messages to better indicate exactly
2789: what pathname failed. (Wayne Davison)
2790:
2791: * Fixed some bugs in the handling of --delete and --exclude when
2792: using the --relative (-R) option. (Wayne Davison)
2793:
2794: * Fixed bug that prevented regular files from replacing
2795: special files and caused a directory in --link-dest or
2796: --compare-dest to block the creation of a file with the
2797: same path. A directory still cannot be replaced by a
2798: regular file unless --delete specified. (J.W. Schultz)
2799:
2800: * Detect and report when open or opendir succeed but read and
2801: readdir fail caused by network filesystem issues and truncated
2802: files. (David Norwood, Michael Brown, J.W. Schultz)
2803:
2804: * Added a fix that should give ssh time to restore the tty settings
2805: if the user presses Ctrl-C at an ssh password prompt.
2806:
2807: INTERNAL:
2808:
2809: * Eliminated vestigial support for old versions that we stopped
2810: supporting. (J.W. Schultz)
2811:
2812: * Simplified some of the option-parsing code. (Wayne Davison)
2813:
2814: * Some cleanup made to the exclude code, as well as some new
2815: defines added to enhance readability. (Wayne Davison)
2816:
2817: * Changed the protocol-version code so that it can interact at a
2818: lower protocol level than the maximum supported by both sides.
2819: Added an undocumented option, --protocol=N, to force the value
2820: we advertise to the other side (primarily for testing purposes).

2838: ENHANCEMENTS:
2839:
2840: * The --delete-after option now implies --delete. (Wayne Davison)
2841:
2842: * The --suffix option can now be used with --backup-dir. (Michael
2843: Zimmerman)
2844:
2845: * Combining "::" syntax with the --rsh/-e option now uses the
2846: specified remote-shell as a transport to talk to a (newly-spawned)
2847: server-daemon. This allows someone to use daemon features, such
2848: as modules, over a secure protocol, such as ssh. (JD Paul)
2849:
2850: * The rsync:// syntax for daemon connections is now accepted in the
2851: destination field.
2852:
2853: * If the file name given to --include-from or --exclude-from is "-",
2854: rsync will read from standard input. (J.W. Schultz)
2855:
2856: * New option --link-dest which is like --compare-dest except that
2857: unchanged files are hard-linked in to the destination directory.
2858: (J.W. Schultz)
2859:
2860: * Don't report an error if an excluded file disappears during an
2861: rsync run. (Eugene Chupriyanov and Bo Kersey)
2862:
2863: * Added .svn to --cvs-exclude list to support subversion. (Jon
2864: Middleton)
2865:
2866: * Properly support IPv6 addresses in the rsyncd.conf "hosts allow"
2867: and "hosts deny" fields. (Hideaki Yoshifuji)
2868:
2869: * Changed exclude file handling to permit DOS or MAC style line
2870: terminations. (J.W. Schultz)
2871:
2872: * Ignore errors from chmod when -p/-a/--preserve-perms is not set.
2873: (Dave Dykstra)
2874:
2875: BUG FIXES:
2876:
2877: * Fix "forward name lookup failed" errors on AIX 4.3.3. (John
2878: L. Allen, Martin Pool)
2879:
2880: * Generate each file's rolling-checksum data as we send it, not
2881: in a separate (memory-eating) pass before hand. This prevents
2882: timeout errors on really large files. (Stefan Nehlsen)
2883:
2884: * Fix compilation on Tru64. (Albert Chin, Zoong Pham)
2885:
2886: * Better handling of some client-server errors. (Martin Pool)
2887:
2888: * Fixed a crash that would occur when sending a list of files that
2889: contains a duplicate name (if it sorts to the end of the file
2890: list) and using --delete. (Wayne Davison)
2891:
2892: * Fixed the file-name duplicate-removal code when dealing with multiple
2893: dups in a row. (Wayne Davison)
2894:
2895: * Fixed a bug that caused rsync to lose the exit status of its child
2896: processes and sometimes return an exit code of 0 instead of showing
2897: an error. (David R. Staples, Dave Dykstra)
2898:
2899: * Fixed bug in --copy-unsafe-links that caused it to be completely
2900: broken. (Dave Dykstra)
2901:
2902: * Prevent infinite recursion in cleanup code under certain circumstances.
2903: (Sviatoslav Sviridov and Marc Espie)
2904:
2905: * Fixed a bug that prevented rsync from creating intervening directories
2906: when --relative-paths/-R is set. (Craig Barratt)
2907:
2908: * Prevent "Connection reset by peer" messages from Cygwin. (Randy O'Meara)

2935: otherwise show expected time to complete. (Cameron Simpson)
2936:
2937: * Make "make install-strip" works properly, and "make install"
2938: accepts a DESTDIR variable for help in building binary packages.
2939: (Peter Breitenlohner, Greg Louis)
2940:
2941: * If configured with --enable-maintainer-mode, then on receipt of
2942: a fatal signal rsync will try to open an xterm running gdb,
2943: similarly to Samba's "panic action" or GNOME's bug-buddy.
2944: (Martin Pool)
2945:
2946:
2947: BUG FIXES:
2948:
2949: * Fix situation where failure to fork (e.g. because out of process

2952:

2959: for remote connections. (Martin Pool, Frank Schulz)
2960:
2961: * Work around bug in Mac OS X mkdir(2), which cannot handle
2962: trailing slashes.

2979:
2980: * Merge in changes from zlib 1.1.3 to zlib 1.1.4. (Jos Backus)
2981: (Note that rsync still uses a custom version of zlib; you can

2998:
2999: * Fix zlib double-free bug. (Owen Taylor, Mark J Cox) (CVE
3000: CAN-2002-0059)
3001:
3002: * Fixed problem that in many cases caused the error message
3003: unexpected read size of 0 in map_ptr
3004: and resulted in the wrong data being copied.
3005:
3006: * Fixed compilation errors on some systems caused by the use of
3007: "unsigned int64" in rsync.h.
3008:
3009: * Fixed problem on systems such as Sunos4 that do not support realloc
3010: on a NULL pointer; error was "out of memory in flist_expand".
3011:
3012: * Fix for rsync server processes hanging around after the client
3013: unexpectedly disconnects. (Colin Walters) (Debian bug #128632)
3014:

3016: slash.
3017:
3018: ENHANCEMENTS:
3019:
3020: * Merge in changes from zlib 1.1.2 to zlib 1.1.3. (Note that
3021: rsync still uses a custom version of zlib; you can not just link
3022: against a system library. See zlib/README.rsync)
3023:
3024: * Command to initiate connections is only shown with -vv, rather
3025: than -v as in 2.5.2. Output from plain -v is more similar to
3026: what was historically used so as not to break scripts that try
3027: to parse the output.
3028:
3029: * Added --no-whole-file and --no-blocking-io options (Dave Dykstra)
3030:
3031: * Made the --write-batch and --read-batch options actually work
3032: and added documentation in the man page (Jos Backus)
3033:
3034: * If the daemon is unable to fork a child to accept a connection,
3035: print an error message. (Colin Walters)

3043:
3044: * Signedness security patch from Sebastian Krahmer
3045: <krahmer@suse.de> -- in some cases we were not sufficiently
3046: careful about reading integers from the network.
3047:
3048: BUG FIXES:
3049:
3050: * Fix possible string mangling in log files.
3051:
3052: * Fix for setting local address of outgoing sockets.
3053:
3054: * Better handling of hardlinks and devices on platforms with
3055: 64-bit dev_t or ino_t.

3060:
3061: ENHANCEMENTS:
3062:
3063: * With -v, rsync now shows the command used to initiate an ssh/rsh
3064: connection.
3065:
3066: * --statistics now shows memory heap usage on platforms that
3067: support mallinfo().
3068:
3069: * "The Ted T'so school of program optimization": make progress
3070: visible and people will think it's faster. (With --progress,
3071: rsync will show you how many files it has seen as it builds the
3072: file_list, giving some indication that it has not hung.)
3073:
3074: * Improvements to batch mode support. This is still experimental
3075: but testing would be welcome. (Jos Backus)
3076:

3078: Vipul's Razor. (Debian #124286)

3108: multiple of bytes/s) and estimated time to completion. (Rik
3109: Faith)
3110:
3111: * --no-detach option, required to run as a W32 service and also
3112: useful when running on Unix under daemontools, AIX's SRC, or a
3113: debugger. (Max Bowsher, Jos Backus)
3114:

3123:
3124: * Martin Pool <mbp@samba.org> is now a co-maintainer.
3125:
3126: NEW FEATURES
3127:

3129:
3130: * Shell wildcards are allowed in "auth users" lines.
3131:
3132: * Merged UNC rsync+ patch to support creation of standalone patch
3133: sets. By Bert J. Dempsey and Debra Weiss, updated by Jos
3134: Backus. <http://www.ils.unc.edu/i2dsi/unc_rsync+.html>
3135:
3136: * IPv6 support based on a patch from KAME.net, on systems
3137: including modern versions of Linux, Solaris, and HP-UX. Also
3138: includes IPv6 compatibility functions for old OSs by the
3139: Internet Software Consortium, Paul Vixie, the OpenSSH
3140: portability project, and OpenBSD.
3141:
3142: ENHANCEMENTS
3143:
3144: * Include/exclude cluestick: with -vv, print out whether files are
3145: included or excluded and why.
3146:
3147: * Many error messages have more friendly explanations and more
3148: details.
3149:
3150: * Manual page improvements plus scanty protocol documentation.
3151:
3152: * When running as --daemon in the background and using a "log
3153: file" rsyncd.conf directive, close the log file every time it is
3154: open when going to sleep on the socket. This allows the log
3155: file to get cleaned out by another process.
3156:
3157: * Change to using libpopt rather than getopt for processing
3158: options. This makes the code cleaner and the behaviour more
3159: consistent across platforms. popt is included and built if not
3160: installed on the platform.
3161:
3162: * More details in --version, including note about whether 64-bit
3163: files, symlinks and hardlinks are supported.
3164:
3165: * MD4 code may use less CPU cycles.
3166:
3167: * Use mkstemp on systems where it is secure. If we use mktemp,
3168: explain that we do it in a secure way.
3169:
3170: * --whole-file is the default when source and target are on the
3171: local machine.
3172:
3173: BUG FIXES:

3176:
3177: * Attempt to fix Large File Summit support on AIX.
3178:
3179: * Attempt to fix error handling lockup bug.
3180:
3181: * Give a non-0 exit code if *any* of the files we have been asked
3182: to transfer fail to transfer.
3183:
3184: * For log messages containing ridiculously long strings that might
3185: overflow a buffer rsync no longer aborts, but rather prints an
3186: ellipsis at the end of the string. (Patch from Ed Santiago.)
3187:
3188: PLATFORMS:
3189:
3190: * Improved support for UNICOS (tested on Cray T3E and Cray SV1)
3191:
3192: * autoconf2.52 (or later) is now required to rebuild the autoconf
3193: scripts. It is not required to simply build rsync.
