1NEWS for rsync 2.6.9 (6 Nov 2006)
2Protocol: 29 (unchanged)
3Changes since 2.6.8:
4
5 BUG FIXES:
6
7 - If rsync is interrupted via a handled signal (such as SIGINT), it will
8 once again clean-up its temp file from the destination dir.
9
10 - Fixed an overzealous sanitizing bug in the handling of the --link-dest,
11 --copy-dest, and --compare-dest options to a daemon without chroot: if
12 the copy's destination dir is deeper than the top of the module's path,
13 these options now accept a safe number of parent-dir (../) references
14 (since these options are relative to the destination dir). The old code
15 incorrectly chopped off all "../" prefixes for these options, no matter
16 how deep the destination directory was in the module's hierarchy.
17
18 - Fixed a bug where a deferred info/error/log message could get sent
19 directly to the sender instead of being handled by rwrite() in the
20 generator. This fixes an "unexpected tag 3" fatal error, and should
21 also fix a potential problem where a deferred info/error message from
22 the receiver might bypass the log file and get sent only to the client
23 process. (These problems could only affect an rsync daemon that was
24 receiving files.)
25
26 - Fixed a bug when --inplace was combined with a --*-dest option and we
27 update a file's data using an alternate basis file. The code now
28 notices that it needs to copy the matching data from the basis file
29 instead of (wrongly) assuming that it was already present in the file.
30
31 - Fixed a bug where using --dry-run with a --*-dest option with a path
32 relative to a directory that does not yet exist: the affected option
33 gets its proper path value so that the output of the dry-run is right.
34
35 - Fixed a bug in the %f logfile escape when receiving files: the
36 destination path is now included in the output (e.g. you can now tell
37 when a user specifies a subdir inside a module).
38
39 - If the receiving side fails to create a directory, it will now skip
40 trying to update everything that is inside that directory.
41
42 - If --link-dest is specified with --checksum but without --times, rsync
43 will now allow a hard-link to be created to a matching link-dest file
44 even when the file's modify-time doesn't match the server's file.
45
46 - The daemon now calls more timezone-using functions prior to doing a
47 chroot. This should help some C libraries to generate proper timestamps
48 from inside a chrooted daemon (and to not try to access /etc/timezone
49 over and over again).
50
51 - Fixed a bug in the handling of an absolute --partial-dir=ABS_PATH option:
52 it now deletes an alternate basis file from the partial-dir that was used
53 to successfully update a destination file.
54
55 - Fixed a bug in the handling of --delete-excluded when using a per-dir
56 merge file: the merge file is now honored on the receiving side, and
57 only its unqualified include/exclude commands are ignored (just as is
58 done for global include/excludes).
59
60 - Fixed a recent bug where --delete was not working when transferring from
61 the root (/) of the filesystem with --relative enabled.
62
63 - Fixed a recent bug where an --exclude='*' could affect the root (/) of
64 the filesystem with --relative enabled.
65
66 - When --inplace creates a file, it is now created with owner read/write
67 permissions (0600) instead of no permissions at all. This avoids a
68 problem continuing a transfer that was interrupted (since --inplace
69 will not update a file that has no write permissions).
70
71 - If either --remove-source-files or --remove-sent-files is enabled and we
72 are unable to remove the source file, rsync now outputs an error.
73
74 - Fixed a bug in the daemon's "incoming chmod" rule: newly-created
75 directories no longer get the 'F' (file) rules applied to them.
76
77 - Fixed an infinite loop bug when a filter rule was rejected due to being
78 overly long.
79
80 - When the server receives a --partial-dir option from the client, it no
81 longer runs the client-side code that adds an assumed filter rule (since
82 the client will be sending us the rules in the usual manner, and they
83 may have chosen to override the auto-added rule).
84
85 ENHANCEMENTS:
86
87 - Added the --log-file=FILE and --log-file-format=FORMAT options. These
88 can be used to tell any rsync to output what it is doing to a log file.
89 They work with a client rsync, a non-daemon server rsync (see the man
90 page for instructions), and also allows the overriding of rsyncd.conf
91 settings when starting a daemon.
92
93 - The --log-format option was renamed to be --out-format to avoid confusing
94 it with affecting the log-file output. (The old option remains as an
95 alias for the new to preserve backward compatibility.)
96
97 - Made "log file" and "syslog facility" settable on a per-module basis in
98 the daemon's config file.
99
100 - Added the --remove-source-files option as a replacement for the (now
101 deprecated) --remove-sent-files option. This new option removes all
102 non-dirs from the source directories, even if the file was already
103 up-to-date. This fixes a problem where interrupting an rsync that
104 was using --remove-sent-files and restarting it could leave behind
105 a file that the earlier rsync synchronized, but didn't get to remove.
106 (The deprecated --remove-sent-files is still understood for now, and
107 still behaves in the same way as before.)
108
109 - Added the option --no-motd to suppress the message-of-the-day output
110 from a daemon when doing a copy. (See the manpage for a caveat.)
111
112 - Added a new environment variable to the pre-/post-xfer exec commands (in
113 the daemon's config file): RSYNC_PID. This value will be the same in
4eeaa162
WD
114 both the pre- and post-xfer commands, so it can be used as a unique ID
115 if the pre-xfer command wants to cache some arg/request info for the
116 post-xfer command.

117
118 INTERNAL:
119
120 - Did a code audit using IBM's code-checker program and made several
121 changes, including: replacing most of the strcpy() and sprintf()
122 calls with strlcpy(), snprintf(), and memcpy(), adding a 0-value to
123 an enum that had been intermingling a literal 0 with the defined enum
124 values, silencing some uninitialized memory checks, marking some
125 functions with a "noreturn" attribute, and changing an "if" that
126 could never succeed on some platforms into a pre-processor directive
127 that conditionally compiles the code.
128
129 - Fixed a potential bug in f_name_cmp() when both the args are a
130 top-level "." dir (which doesn't happen in normal operations).
131
132 - Changed exit_cleanup() so that it can never return instead of exit.
133 The old code might return if it found the exit_cleanup() function
134 was being called recursively. The new code is segmented so that
135 any recursive calls move on to the next step of the exit-processing.
136
137 - The macro WIFEXITED(stat) will now be defined if the OS didn't already
138 define it.
139
140 DEVELOPER RELATED:
141
142 - The acls.diff and xattrs.diff patches have received a bunch of work to
143 make them much closer to being acceptable in the main distribution.
144 The xattrs patch also has some preliminary Mac OS X and FreeBSD
145 compatibility code that various system types to exchange extended
146 file-attributes.
147
148 - A new diff in the patches dir, fake-root.diff, allows rsync to
149 maintain a backup hierarchy with full owner, group, and device info
150 without actually running as root. It does this using a special
151 extended attribute, so it depends on xattrs.diff (which depends on
152 acls.diff).
153
154 - The rsync.yo and rsyncd.conf.yo files have been updated to work
155 better with the latest yodl 2.x releases.
156
157 - Updated config.guess and config.sub to their 2006-07-02 versions.
158
159 - Updated various files to include the latest FSF address and to have

163NEWS for rsync 2.6.8 (22 Apr 2006)
164Protocol: 29 (unchanged)
165Changes since 2.6.7:
166
167 BUG FIXES:
168
169 - Fixed a bug in the exclude code where an anchored exclude without any
170 wildcards fails to match an absolute source arg, but only when --relative
171 is in effect.
172
173 - Improved the I/O code for the generator to fix a potential hang when the
174 receiver gets an EOF on the socket but the generator's select() call
175 never indicates that the socket is writable for it to be notified about
176 the EOF. (This can happen when using stunnel).
177
178 - Fixed a problem with the file-reading code where a failed read (such as
180 beyond the failed read's data.
181
182 - Fixed a logging bug where the "log file" directive was not being honored
183 in a single-use daemon (one spawned by a remote-shell connection or by
184 init).
185
186 - If rsync cannot honor the --delete option, we output an error and exit
187 instead of silently ignoring the option.
188
189 - Fixed a bug in the --link-dest code that prevented special files (such as
191
192 - The ability to hard-link symlinks and special files is now determined at
193 configure time instead of at runtime. This fixes a bug with --link-dest
194 creating a hard-link to a symlink's referent on a BSD system.
195
196 ENHANCEMENTS:
197
198 - In daemon mode, if rsync fails to bind to the requested port, the
199 error(s) returned by socket() and/or bind() are now logged.
200
201 - When we output a fatal error, we now output the version of rsync in the
202 message.
203
204 - Improved the documentation for the --owner and --group options.
205
206 - The rsyncstats script in "support" has an improved line-parsing regex
207 that is easier to read and also makes it to parse syslog-generated lines.
208
209 - A new script in "support": file-attr-restore, can be used to restore the
210 attributes of a file-set (the permissions, ownership, and group info)
211 taken from the cached output of a "find ARG... -ls" command.
212
213 DEVELOPER RELATED:
214
215 - Removed the unused function write_int_named(), the unused variable
216 io_read_phase, and the rarely used variable io_write_phase. This also
217 elides the confusing 'phase "unknown"' part of one error message.
218
219 - Removed two unused configure checks and two related (also unused)
220 compatibility functions.
221
222 - The xattrs.diff patch received a security fix that prevents a potential
223 buffer overflow in the receive_xattr() code.
224
225 - The acls.diff patch has been improved quite a bit, with more to come.
226
227 - A new patch was added: log-file.diff. This contains an early version of
228 a future option, --log-file=FILE, that will allow any rsync to log its
229 actions to a file (something that only a daemon supports at present).

232NEWS for rsync 2.6.7 (11 Mar 2006)
233Protocol: 29 (unchanged)
234Changes since 2.6.6:
235
236 OUTPUT CHANGES:
237
238 - The letter 'D' in the itemized output was being used for both devices
239 (character or block) as well as other special files (such as fifos and
240 named sockets). This has changed to separate non-device special files
242 "--specials" option, below.
243
244 - The way rsync escapes unreadable characters has changed. First, rsync
245 now has support for recognizing valid multibyte character sequences in
246 your current locale, allowing it to escape fewer characters than before
247 for a locale such as UTF-8. Second, it now uses an escape idiom of
248 "\#123", which is the literal string "\#" followed by exactly 3 octal
249 digits. Rsync no longer doubles a backslash character in a filename
250 (e.g. it used to output "foo\\bar" when copying "foo\bar") -- now it only
251 escapes a backslash that is followed by a hash-sign and 3 digits (0-9)
253 the --8-bit-output (-8) option, mentioned below.
254
255 Script writers: the local rsync is the one that outputs escaped names,
256 so if you need to support unescaping of filenames for older rsyncs, I'd
257 suggest that you parse the output of "rsync --version" and only use the
258 old unescaping rules for 2.6.5 and 2.6.6.
259
260 BUG FIXES:
261
262 - Fixed a really old bug that caused --checksum (-c) to checksum all the
263 files encountered during the delete scan (ouch).
264
265 - Fixed a potential hang in a remote generator: when the receiver gets a
267 the generator does not try to send any of the terminating error messages
268 to the client (avoiding a potential hang in some setups).
269
271
272 - If the sender gets an early EOF reading a source file, we propagate this
273 error to the receiver so that it can discard the file and try requesting
274 it again (which is the existing behavior for other kinds of read errors).
275
276 - If a device-file/special-file changes permissions, rsync now updates the
277 permissions without recreating the file.
278
279 - If the user specifies a remote-host for both the source and destination,
280 we now output a syntax error rather than trying to open the destination
281 hostspec as a filename.
282
283 - When --inplace creates a new destination file, rsync now creates it with
284 permissions 0600 instead of 0000 -- this makes restarting possible when
285 the transfer gets interrupted in the middle of sending a new file.
286
287 - Reject the combination of --inplace and --sparse since the sparse-output
288 algorithm doesn't work when overwriting existing data.
289
290 - Fixed the directory name in the error that is output when pop_dir()
291 fails.
292
293 - Really fixed the parsing of a "!" entry in .cvsignore files this time.
294
295 - If the generator gets a stat() error on a file, output it (this used to
296 require at least -vv for the error to be seen).
297
298 - If waitpid() fails or the child rsync didn't exit cleanly, we now handle
299 the exit status properly and generate a better error.
300
301 - Fixed some glitches in the double-verbose output when using --copy-dest,
302 --link-dest, or --compare-dest. Also improved how the verbose output
304 "dest" file, and copied files (via --copy-dest).
305
306 - Fixed the matching of the dont-compress items (e.g. *.gz) against files
307 that have a path component containing a slash.
308
549a3efb
WD
309 - If the code reading a filter/exclude file gets an EINTR error, rsync now
310 clears the error flag on the file handle so it can keep on reading.
f171bf5b
WD
311
312 - If --relative is active, the sending side cleans up trailing "/" or "/."
313 suffixes to avoid triggering a bug in older rsync versions. Also, we now
314 reject a ".." dir if it would be sent as a relative dir.
315
316 - If a non-directory is in the way of a directory and rsync is run with
317 --dry-run and --delete, rsync no longer complains about not being able
318 to opendir() the not-yet present directory.
319
320 - When --list-only is used and a non-existent local destination dir was
321 also specified as a destination, rsync no longer generates a warning
322 about being unable to create the missing directory.
323
324 - Fixed some problems with --relative --no-implied-dirs when the
325 destination directory did not yet exist: we can now create a symlink or
326 device when it is the first thing in the missing dir, and --fuzzy no
327 longer complains about being unable to open the missing dir.
328
329 - Fixed a bug where the --copy-links option would not affect implied
330 directories without --copy-unsafe-links (see --relative).
331
332 - Got rid of the need for --force to be used in some circumstances with
333 --delete-after (making it consistent with --delete-before/-during).
334
335 - Rsync now ignores the SIGXFSZ signal, just in case your OS sends this
336 when a file is too large (rsync handles the write error).
337
338 - Fixed a bug in the Proxy-Authorization header's base64-encoded value: it
339 was not properly padded with trailing '=' chars. This only affects a
340 user that need to use a password-authenticated proxy for an outgoing
341 daemon-rsync connection.
342
343 - If we're transferring an empty directory to a new name, rsync no longer
344 forces S_IWUSR if it wasn't already set, nor does it accidentally leave
345 it set.
346
347 - Fixed a bug in the debug output (-vvvvv) that could mention the wrong
348 checksum for the current file offset.
349
350 - Rsync no longer allows a single directory to be copied over a non-
351 directory destination arg.
352
353 ENHANCEMENTS:
354
355 - Added the --append option that makes rsync append data onto files that
356 are longer on the source than the destination (this includes new files).
357
358 - Added the --min-size=SIZE option to exclude small files from the
359 transfer.
360
361 - Added the --compress-level option to allow you to set how aggressive
362 rsync's compression should be (this option implies --compress).
363
364 - Enhanced the parsing of the SIZE value for --min-size and --max-size to
365 allow easy entry of multiples of 1000 (instead of just multiples of 1024)
366 and off-by-one values too (e.g. --max-size=8mb-1).
367
368 - Added the --8-bit-output (-8) option, which tells rsync to avoid escaping
369 high-bit characters that it thinks are unreadable in the current locale.
370
371 - The new option --human-readable (-h) changes the output of --progress,
372 --stats, and the end-of-run summary to be easier to read. If repeated,
373 the units become powers of 1024 instead of powers of 1000. (The old
374 meaning of -h, as a shorthand for --help, still works as long as you
375 just use it on its own, as in "rsync -h".)
376
377 - If lutimes() and/or lchmod() are around, use them to allow the
378 preservation of attributes on symlinks.
379
380 - The --link-dest option now affects symlinks and devices (when possible).
381
382 - Added two config items to the rsyncd.conf parsing: "pre-xfer exec" and
383 "post-xfer exec". These allow a command to be specified on a per-module
384 basis that will be run before and/or after a daemon-mode transfer. (See
385 the man page for a list of the environment variables that are set with
387
388 - When using the --relative option, you can now insert a dot dir in
389 the source path to indicate where the replication of the source dirs
390 should start. For example, if you specify a source path of
391 rsync://host/module/foo/bar/./baz/dir with -R, rsync will now only
392 replicate the "baz/dir" part of the source path (note: a trailing
393 dot dir is unaffected unless it also has a trailing slash).
394
395 - Added some new --no-FOO options that make it easier to override unwanted
396 implied or default options. For example, "-a --no-o" (aka "--archive
397 --no-owner") can be used to turn off the preservation of file ownership
398 that is implied by -a.
399
400 - Added the --chmod=MODE option that allows the destination permissions to
401 be changed from the source permissions. E.g. --chmod=g+w,o-rwx
402
403 - Added the "incoming chmod" and "outgoing chmod" daemon options that allow
404 a module to specify what permissions changes should be applied to all
405 files copied to and from the daemon.
406
407 - Allow the --temp-dir option to be specified when starting a daemon, which
408 sets the default temporary directory for incoming files.
409
410 - If --delete is combined with --dirs without --recursive, rsync will now
411 delete in any directory whose content is being synchronized.
412
413 - If --backup is combined with --delete without --backup-dir (and without
414 --delete-excluded), we add a "protect" filter-rule to ensure that files
415 with the backup suffix are not deleted.
416
417 - The file-count stats that are output by --progress were improved to
418 better indicate what the numbers mean. For instance, the output:
419 "(xfer#5, to-check=8383/9999)" indicates that this was the fifth file
420 to be transferred, and we still need to check 8383 more files out of
421 a total of 9999.
422
423 - The include/exclude code now allows a dir/*** directive (with 3 trailing
424 stars) to match both the dir itself as well as all the content below the
425 dir (dir/** would not match the dir).
426
427 - Added the --prune-empty-dirs (-m) option that makes the receiving rsync
428 discard empty chains of directories from the file-list. This makes it
429 easier to selectively copy files from a source hierarchy and end up with
430 just the directories needed to hold the resulting files.
431
432 - If the --itemize-changes (-i) option is repeated, rsync now includes
433 unchanged files in the itemized output (similar to -vv, but without all
434 the other verbose messages that can get in the way). Of course, the
435 client must be version 2.6.7 for this to work, but the remote rsync only
436 needs to be 2.6.7 if you're pushing files.
437
438 - Added the --specials option to tell rsync to copy non-device special
439 files (which rsync now attempts even as a normal user). The --devices
440 option now requests the copying of just devices (character and block).
441 The -D option still requests both (e.g. --devices and --specials), -a
442 still implies -D, and non-root users still get a silent downgrade that
443 omits device copying.
444
445 - Added the --super option to make the receiver always attempt super-user
446 activities. This is useful for systems that allow things such as devices
447 to be created or ownership to be set without being UID 0, and is also
448 useful for someone who wants to ensure that errors will be output if the
449 receiving rsync isn't being run as root.
450
451 - Added the --sockopts option for those few who want to customize the TCP
452 options used to contact a daemon rsync.
453
454 - Added a way for the --temp-dir option to be combined with a partial-dir
455 setting that lets rsync avoid non-atomic updates (for those times when
456 --temp-dir is not being used because space is tight).
457
458 - A new support script, files-to-excludes, will transform a list of files
459 into a set of include/exclude directives that will copy those files.
460
461 - A new option, --executability (-E) can be used to preserve just the
462 execute bit on files, for those times when using the --perms option is
463 not desired.
464
465 - The daemon now logs each connection and also each module-list request
467
468 - New log-format options: %M (modtime), %U (uid), %G (gid), and %B
469 (permission bits, e.g. "rwxr-xrwt").
470
471 - The --dry-run option no longer forces the enabling of --verbose.
472
473 - The --remove-sent-files option now does a better job of incrementally
474 removing the sent files on the sending side (older versions tended to
475 clump up all the removals at the end).
476
477 - A daemon now supersedes its minimal SIGCHLD handler with the standard
478 PID-remembering version after forking. This ensures that the generator
479 can get the child-exit status from the receiver.
480
481 - Use of the --bwlimit option no longer interferes with the remote rsync
482 sending error messages about invalid/refused options.
483
484 - Rsync no longer returns a usage error when used with one local source arg
485 and no destination: this now implies the --list-only option, just like
486 the comparable situation with a remote source arg.
487
489
490 - Various documentation improvements, including: a better synopsis, some
491 improved examples, a better discussion of the presence and absence of
492 --perms (including how it interacts with the new --executability and
493 --chmod options), an extended discussion of --temp-dir, an improved
494 discussion of --partial-dir, a better description of rsync's pattern
495 matching characters, an improved --no-implied-dirs section, and the
496 documenting of what the --stats option outputs.
497
498 - Various new and updated diffs in the patches dir, including: acls.diff,
499 xattrs.diff, atimes.diff, detect-renamed.diff, and slp.diff.
500
501 INTERNAL:
502
503 - We now use sigaction() and sigprocmask() if possible, and fall back on
504 signal() if not. Using sigprocmask() ensures that rsync enables all the
505 signals that it needs, just in case it was started in a masked state.
506
507 - Some buffer sizes were expanded a bit, particularly on systems where
508 MAXPATHLEN is overly small (e.g. cygwin).
509
510 - If io_printf() tries to format more data than fits in the buffer, exit
511 with an error instead of transmitting a truncated buffer.
512
513 - If a va_copy macro is defined, lib/snprintf.c will use it when defining
514 the VA_COPY macro.
515
516 - Reduced the amount of stack memory needed for each level of directory
517 recursion by nearly MAXPATHLEN bytes.
518
519 - The wildmatch function was extended to allow an array of strings to be
520 supplied as the string to match. This allows the exclude code to do less
521 string copying.
522
523 - Got rid of the safe_fname() function (and all the myriad calls) and
524 replaced it with a new function in the log.c code that filters all the
525 output going to the terminal.
526
527 - Unified the f_name() and the f_name_to() functions.
528
529 - Improved the hash-table code the sender uses to handle checksums to make
530 it use slightly less memory and run just a little faster.
531
532 DEVELOPER RELATED:
533
534 - The diffs in the patches dir now require "patch -p1 <DIFF" instead of
535 the previous -p0. Also, the version included in the release tar now
536 affect generated files (e.g. configure, rsync.1, proto.h, etc.), so
537 it is no longer necessary to run autoconf and/or yodl unless you're
538 applying a patch that was checked out from CVS.
539
540 - Several diffs in the patches dir now use the proper --enable-FOO
541 configure option instead of --with-FOO to turn on the inclusion of
542 the newly patched feature.
543
544 - There is a new script, "prepare-source" than can be used to update the
545 various generated files (proto.h, configure, etc.) even before configure
546 has created the Makefile (this is mainly useful when patching the source
547 with a patch that doesn't affect generated files).
548
549 - The testsuite now sets HOME so that it won't be affected by a file such
550 as ~/.popt.

553NEWS for rsync 2.6.6 (28 Jul 2005)
554Protocol: 29 (unchanged)
555Changes since 2.6.5:
556
557 SECURITY FIXES:
558
559 - The zlib code was upgraded to version 1.2.3 in order to make it more
560 secure. While the widely-publicized security problem in zlib 1.2.2 did
561 not affect rsync, another security problem surfaced that affects rsync's
562 zlib 1.1.4.
563
564 BUG FIXES:
565
566 - The setting of flist->high in clean_flist() was wrong for an empty list.
567 This could cause flist_find() to crash in certain rare circumstances
568 (e.g. if just the right directory setup was around when --fuzzy was
570
571 - The outputting of hard-linked files when verbosity was > 1 was not right:
1578919c
WD
572 (1) Without -i it would output the name of each hard-linked file as
573 though it had been changed; it now outputs a "is hard linked" message for
574 the file. (2) With -i it would output all dots for the unchanged
575 attributes of a hard-link; it now changes those dots to spaces, as is
576 done for other totally unchanged items.
f90f7149
WD
577
578 - When backing up a changed symlink or device, get rid of any old backup
579 item so that we don't get an "already exists" error.
580
581 - A couple places that were comparing a local and a remote modification-
582 time were not honoring the --modify-window option.
583
584 - Fixed a bug where the 'p' (permissions) itemized-changes flag might get
585 set too often (if some non-significant mode bits differed).
586
587 - Fixed a really old, minor bug that could cause rsync to warn about being
588 unable to mkdir() a path that ends in "/." because it just created the
589 directory (required --relative, --no-implied-dirs, a source path that
590 ended in either a trailing slash or a trailing "/.", and a non-existing
592
593 ENHANCEMENTS:
594
595 - Made the "max verbosity" setting in the rsyncd.conf file settable on a
596 per-module basis (which now matches the documentation).
597
598 - The support/rrsync script has been upgraded to verify the args of options
599 that take args (instead of rejecting any such options). The script was
600 also changed to try to be more secure and to fix a problem in the parsing
601 of a pull operation that has multiple sources.
602
603 - Improved the documentation that explains the difference between a
604 normal daemon transfer and a daemon-over remote-shell transfer.
605
606 - Some of the diffs supplied in the patches dir were fixed and/or
607 improved.
608
609 BUILD CHANGES:
610
611 - Made configure define NOBODY_USER (currently hard-wired to "nobody") and
612 NOBODY_GROUP (set to either "nobody" or "nogroup" depending on what we
613 find in the /etc/group file).
614
615 - Added a test to the test suite, itemized.test, that tests the output of
616 -i (log-format w/%i) and some double-verbose messages.

619NEWS for rsync 2.6.5 (1 Jun 2005)
620Protocol: 29 (unchanged)
621Changes since 2.6.4:
622
623 OUTPUT CHANGES:
624
625 - Non-printable chars in filenames are now output using backslash-
626 escaped characters rather than '?'s. Any non-printable character is
627 output using 3 digits of octal (e.g. "\n" -> "\012"), and a backslash
628 is now output as "\\". Rsync also uses your locale setting, which
629 can make it treat fewer high-bit characters as non-printable.
630
631 - If rsync received an empty file-list when pulling files, it would
632 output a "nothing to do" message and exit with a 0 (success) exit
633 status, even if the remote rsync returned an error (it did not do
634 this under the same conditions when pushing files). This was changed
635 to make the pulling behavior the same as the pushing behavior: we
636 now do the normal end-of-run outputting (depending on options) and
637 exit with the appropriate exit status.
638
639 BUG FIXES:
640
641 - A crash bug was fixed when a daemon had its "path" set to "/", did
642 not have chroot enabled, and used some anchored excludes in the
643 rsyncd.conf file.
644
645 - Fixed a bug in the transfer of a single file when -H is specified
646 (rsync would either infinite loop or perhaps crash).
647
648 - Fixed a case where the generator might try (and fail) to tweak the
649 write-permissions of a read-only directory in list-only mode (this
650 only caused an annoying warning message).
651
652 - If --compare-dest or --link-dest uses a locally-copied file as the
653 basis for an updated version, log this better when --verbose or -i
654 is in effect.
655
656 - Fixed the accidental disabling of --backup during the --delete-after
657 processing.
658
659 - Restored the ability to use the --address option in client mode (in
660 addition to its use in daemon mode).
661
662 - Make sure that some temporary progress information from the delete
663 processing does not get left on the screen when it is followed by a
664 newline.
665
666 - When --existing skips a directory with extra verbosity, refer to it
667 as a "directory", not a "file".
668
669 - When transferring a single file to a different-named file, any
670 generator messages that are source-file related no longer refer to
671 the file by the destination filename.
672
673 - Fixed a bug where hard-linking a group of files might fail if the
674 generator hasn't created a needed destination directory yet.
675
676 - Fixed a bug where a hard-linked group of files that is newly-linked
677 to a file in a --link-dest dir doesn't link the files from the rest
678 of the cluster.
679
680 - When deleting files with the --one-file-system (-x) option set, rsync
681 no longer tries to remove files from inside a mount-point on the
682 receiving side. Also, we don't complain about being unable to remove
683 the mount-point dir.
684
685 - Fixed a compatibility problem when using --cvs-ignore (-C) and
686 sending files to an older rsync without using --delete.
687
688 - Make sure that a "- !" or "+ !" include/exclude pattern does not
689 trigger the list-clearing action that is reserved for "!".
690
691 - Avoid a timeout in the generator when the sender/receiver aren't
692 handling the generator's checksum output quickly enough.
693
694 - Fixed the omission of some directories in the delete processing when
695 --relative (-R) was combined with a source path that had a trailing
696 slash.
697
698 - Fixed a case where rsync would erroneously delete some files and then
699 re-transfer them when the options --relative (-R) and --recursive
700 (-r) were both enabled (along with --delete) and a source path had a
701 trailing slash.
702
703 - Make sure that --max-size doesn't affect a device or a symlink.
704
705 - Make sure that a system with a really small MAXPATHLEN does not cause
706 the buffers in readfd_unbuffered() to be too small to receive normal
707 messages. (This mainly affected Cygwin.)
708
709 - If a source pathname ends with a filename of "..", treat it as if
710 "../" had been specified (so that we don't copy files to the parent
711 dir of the destination).
712
713 - If --delete is combined with a file-listing rsync command (i.e. no
714 transfer is happening), avoid outputting a warning that we couldn't
715 delete anything.
716
717 - If --stats is specified with --delete-after, ensure that all the
718 "deleting" messages are output before the statistics.
719
720 - Improved one "if" in the deletion code that was only checking errno
721 for ENOTEMPTY when it should have also been checking for EEXIST (for
722 compatibility with OS variations).
723
724 ENHANCEMENTS:
725
727 of --write-batch=FILE) to create a batch file without doing any
728 actual updating of the destination. This allows you to divert all
729 the file-updating data away from a slow data link (as long as you
730 are pushing the data to the remote server when creating the batch).
731
732 - When the generator is taking a long time to fill up its output buffer
733 (e.g. if the transferred files are few, small, or missing), it now
734 periodically flushes the output buffer so that the sender/receiver
735 can get started on the files sooner rather than later.
736
737 - Improved the keep-alive code to handle a long silence between the
738 sender and the receiver that can occur when the sender is receiving
739 the checksum data for a large file.
740
741 - Improved the auth-errors that are logged by the daemon to include
742 some information on why the authorization failed: wrong user,
743 password mismatch, etc. (The client-visible message is unchanged!)
744
745 - Improved the client's handling of an "@ERROR" from a daemon so that
746 it does not complain about an unexpectedly closed socket (since we
747 really did expect the socket to close).
748
749 - If the daemon can't open the log-file specified in rsyncd.conf, fall
750 back to using syslog and log an appropriate warning. This is better
751 than what was typically a totally silent (and fatal) failure (since a
752 daemon is not usually run with the --no-detach option that was
753 necessary to see the error on stderr).
754
755 - The man pages now consistently refer to an rsync daemon as a "daemon"
756 instead of a "server" (to distinguish it from the server process in a
757 non-daemon transfer).
758
759 - Made a small change to the rrsync script (restricted rsync -- in the
760 support dir) to make a read-only server reject all --remove-* options
761 when sending files (to future-proof it against the possibility of
762 other similar options being added at some point).
763
764 INTERNAL:
765
766 - Rsync now calls setlocale(LC_CTYPE, ""). This enables isprint() to
767 better discern which filename characters need to be escaped in
768 messages (which should result in fewer escaped characters in some
769 locales).
770
771 - Improved the naming of the log-file open/reopen/close functions.
772
773 - Removed some protocol-compatibility code that was only needed to help
774 someone running a pre-release of 2.6.4.
775
776 BUILD CHANGES:
777
778 - Added configure option "--disable-locale" to disable any use of
779 setlocale() in the binary.
780
781 - Fixed a bug in the SUPPORT{,_HARD}_LINKS #defines which prevented
783
784 - Only #define HAVE_REMSH if it is going to be set to 1.
785
786 - Configure now disables the use of mkstemp() under HP-UX (since they
787 refuse to fix its broken handling of large files).
788
789 - Configure now explicitly checks for the lseek64() function so that
790 the code can use HAVE_LSEEK64 instead of inferring lseek64()'s
791 presence based on the presence of the off64_t type.
792
793 - Configure no longer mentions the change in the default remote-shell
794 (from rsh to ssh) that occurred for the 2.6.0 release.
795
796 - Some minor enhancements to the test scripts.
797
798 - Added a few new *.diff files to the patches dir, including a patch
799 that enables the optional copying of extended attributes.

802NEWS for rsync 2.6.4 (30 March 2005)
803Protocol: 29 (changed)
804Changes since 2.6.3:
805
806 OUTPUT CHANGES:
807
808 - When rsync deletes a directory and outputs a verbose message about
809 it, it now appends a trailing slash to the name instead of (only
810 sometimes) outputting a preceding "directory " string.
811
812 - The --stats output will contain file-list time-statistics if both
813 sides are 2.6.4, or if the local side is 2.6.4 and the files are
814 being pushed (since the stats come from the sending side).
815 (Requires protocol 29 for a pull.)
816
817 - The "%o" (operation) log-format escape now has a third value (besides
818 "send" and "recv"): "del." (with trailing dot to make it 4 chars).
819 This changes the way deletions are logged in the daemon's log file.
820
821 - When the --log-format option is combined with --verbose, rsync now
822 avoids outputting the name of the file twice in most circumstances.
823 As long as the --log-format item does not refer to any post-transfer
824 items (such as %b or %c), the --log-format message is output prior to
825 the transfer, so --verbose is now the equivalent of a --log-format of
826 '%n%L' (which outputs the name and any link info). If the log output
827 must occur after the transfer to be complete, the only time the name
828 is also output prior to the transfer is when --progress was specified
829 (so that the name will precede the progress stats, and the full
830 --log-format output will come after).
97e3c50c 831
7c2a83c6
WD
832 - Non-printable characters in filenames are replaced with a '?' to
833 avoid corrupting the screen or generating empty lines in the output.
WD
834
835 BUG FIXES:
836
837 - Restore the list-clearing behavior of "!" in a .cvsignore file (2.6.3
838 was only treating it as a special token in an rsync include/exclude
839 file).
840
841 - The combination of --verbose and --dry-run now mentions the full list
842 of changes that would be output without --dry-run.
843
844 - Avoid a mkdir warning when removing a directory in the destination
845 that already exists in the --backup-dir.
846
847 - An OS that has a binary mode for its files (such as cygwin) needed
848 setmode(fd, O_BINARY) called on the temp-file we opened with
10a1a3f5 849 mkstemp(). (Fix derived from cygwin's 2.6.3 rsync package.)
WD
850
851 - Fixed a potential hang when verbosity is high, the client side is
852 the sender, and the file-list is large.
853
854 - Fixed a potential protocol-corrupting bug where the generator could
855 merge a message from the receiver into the middle of a multiplexed
856 packet of data if only part of that data had been written out to the
857 socket when the message from the generator arrived.
858
859 - We now check if the OS doesn't support using mknod() for creating
860 FIFOs and sockets, and compile-in some compatibility code using
861 mkfifo() and socket() when necessary.
862
863 - Fixed an off-by-one error in the handling of --max-delete=N. Also,
864 if the --max-delete limit is exceeded during a run, we now output a
866 code (25).
867
868 - One place in the code wasn't checking if fork() failed.
869
870 - The "ignore nonreadable" daemon parameter used to erroneously affect
872
873 - If the OS does not have lchown() and a chown() of a symlink will
874 affect the referent of a symlink (as it should), we no longer try
875 to set the user and group of a symlink.
876
877 - The generator now properly runs the hard-link loop and the dir-time
878 rewriting loop after we're sure that the redo phase is complete.
879
880 - When --backup was specified with --partial-dir=DIR, where DIR is a
881 relative path, the backup code was erroneously trying to backup a
882 file that was put into the partial-dir.
883
884 - If a file gets resent in a single transfer and the --backup option is
885 enabled along with --inplace, rsync no longer performs a duplicate
886 backup (it used to overwrite the first backup with the failed file).
887
888 - One call to flush_write_file() was not being checked for an error.
889
890 - The --no-relative option was not being sent from the client to a
891 server sender.
892
893 - If an rsync daemon specified "dont compress = ..." for a file and the
894 client tried to specify --compress, the libz code was not handling a
895 compression level of 0 properly. This could cause a transfer failure
896 if the block-size for a file was large enough (e.g. rsync might have
897 exited with an error for large files).
898
899 - Fixed a bug that would sometimes surface when using --compress and
900 sending a file with a block-size larger than 64K (either manually
901 specified, or computed due to the file being really large). Prior
902 versions of rsync would sometimes fail to decompress the data
903 properly, and thus the transferred file would fail its verification.
904
905 - If a daemon can't open the specified log file (i.e. syslog is not
906 being used), die without crashing. We also output an error about
907 the failure on stderr (which will only be seen if --no-detach was
908 specified) and exit with a new error code (6).
909
910 - A local transfer no longer duplicates all its include/exclude options
911 (since the forked process already has a copy of the exclude list,
912 there's no need to send them a set of duplicates).
913
7eb2ecda
WD
914 - The output of the items that are being updated by the generator (dirs,
915 symlinks, devices) is now intermingled in the proper order with the
916 output from the items that the receiver is updating (regular files)
917 when pulling. This misordering was particularly bad when --progress
918 was specified. (Requires protocol 29.)
WD
919
920 - When --timeout is specified, lulls that occur in the transfer while
921 the generator is doing work that does not generate socket traffic
922 (looking for changed files, deleting files, doing directory-time
923 touch-ups, etc.) will cause a new keep-alive packet to be sent that
924 should keep the transfer going as long as the generator continues to
925 make progress. (Requires protocol 29.)
926
927 - The stat size of a device is not added to the total file size of the
928 items in the transfer (the size might be undefined on some OSes).
929
930 - Fixed a problem with refused-option messages sometimes not making it
931 back to the client side when a remote --files-from was in effect and
932 the daemon was the receiver.
933
0f9941dc 934 - The --compare-dest option was not updating a file that differed in
WD
935 (the preserved) attributes from the version in the compare-dest DIR.
936
937 - When rsync is copying files into a write-protected directory, fixed
938 the change-report output for the directory so that we don't report
939 an identical directory as changed.
940
941 ENHANCEMENTS:
942
943 - Rsync now supports popt's option aliases, which means that you can
944 use /etc/popt and/or ~/.popt to create your own option aliases.
945
946 - Added the --delete-during (--del) option which will delete files
947 from the receiving side incrementally as each directory in the
948 transfer is being processed. This makes it more efficient than the
949 default, before-the-transfer behavior, which is now also available as
950 --delete-before (and is still the default --delete-WHEN option that
951 will be chosen if --delete or --delete-excluded is specified without
952 a --delete-WHEN choice). All the --del* options infer --delete, so
953 an rsync daemon that refuses "delete" will still refuse to allow any
954 file-deleting options (including the new --remove-sent-files option).
955
956 - All the --delete-WHEN options are now more memory efficient:
957 Previously an duplicate set of file-list objects was created on the
958 receiving side for the entire destination hierarchy. The new
959 algorithm only creates one directory of objects at a time (for files
960 inside the transfer).
961
964
965 - Added support for specifying multiple --compare-dest, --copy-dest, or
966 --link-dest options, but only of a single type. (Promoted from the
967 patches dir and enhanced.) (Requires protocol 29.)
968
969 - Added the --max-size option. (Promoted from the patches dir.)
970
971 - The daemon-mode options are now separated from the normal rsync
972 options so that they can't be mixed together. This makes it
973 impossible to start a daemon that has improper default option values
974 (which could cause problems when a client connects, such as hanging
975 or crashing).
976
977 - The --bwlimit option may now be used in combination with --daemon
978 to specify both a default value for the daemon side and a value
979 that cannot be exceeded by a user-specified --bwlimit option.
980
981 - Added the "port" parameter to the rsyncd.conf file. (Promoted from
983 take precedence over a config-file option, as expected.
984
985 - In _exit_cleanup(): when we are exiting with a partially-received
986 file, we now flush any data in the write-cache before closing the
987 partial file.
988
989 - The --inplace support was enhanced to work with --compare-dest,
990 --link-dest, and (the new) --copy-dest options. (Requires protocol
991 29.)
992
993 - Added the --dirs (-d) option for an easier way to copy directories
af6155bb
WD
994 without recursion. Any directories that are encountered are created
995 on the destination. Specifying a directory with a trailing slash
996 copies its immediate contents to the destination.
997
998 - The --files-from option now implies --dirs (-d).
WD
999
1000 - Added the --list-only option, which is mainly a way for the client to
1001 put the server into listing mode without needing to resort to any
1002 internal option kluges (e.g. the age-old use of "-r --exclude="/*/*"
1003 for a non-recursive listing). This option is used automatically
1004 (behind the scenes) when a modern rsync speaks to a modern daemon,
1005 but may also be specified manually if you want to force the use of
1006 the --list-only option over a remote-shell connection.
1007
1008 - Added the --omit-dir-times (-O) option, which will avoid updating
1009 the modified time for directories when --times was specified. This
1010 option will avoid an extra pass through the file-list at the end of
1011 the transfer (to tweak all the directory times), which may provide
1012 an appreciable speedup for a really large transfer. (Promoted from
1013 the patches dir.)
1014
1015 - Added the --filter (-f) option and its helper option, -F. Filter
1016 rules are an extension to the existing include/exclude handling
1017 that also supports nested filter files as well as per-directory
1018 filter files (like .cvsignore, but with full filter-rule parsing).
1019 This new option was chosen in order to ensure that all existing
1020 include/exclude processing remained 100% compatible with older
1021 versions. Protocol 29 is needed for full filter-rule support, but
1022 backward-compatible rules work with earlier protocol versions.
1023 (Promoted from the patches dir and enhanced.)
1024
1025 - Added the --delay-updates option that puts all updated files into
1026 a temporary directory (by default ".~tmp~", but settable via the
1027 --partial-dir=DIR option) until the end of the transfer. This
1028 makes the updates a little more atomic for a large transfer.
1029
1030 - If rsync is put into the background, any output from --progress is
1031 reduced.
1032
1033 - Documented the "max verbosity" setting for rsyncd.conf. (This
1034 setting was added a couple releases ago, but left undocumented.)
1035
1036 - The sender and the generator now double-check the file-list index
1037 they are given, and refuse to try to do a file transfer on a
1038 non-file index (since that would indicate that something had gone
1039 very wrong).
1040
1041 - Added the --itemize-changes (-i) option, which is a way to output a
1042 more detailed list of what files changed and in what way. The effect
1043 is the same as specifying a --log-format of "%i %n%L" (see both the
1044 rsync and rsyncd.conf manpages). Works with --dry-run too.
1045
1046 - Added the --fuzzy (-y) option, which attempts to find a basis file
1047 for a file that is being created from scratch. The current algorithm
1048 only looks in the destination directory for the created file, but it
1049 does attempt to find a match based on size/mod-time (in case the file
1050 was renamed with no other changes) as well as based on a fuzzy
1051 name-matching algorithm. This option requires protocol 29 because it
1052 needs the new file-sorting order. (Promoted from patches dir and
1053 enhanced.) (Requires protocol 29.)
1054
1055 - Added the --remove-sent-files option, which lets you move files
1056 between systems.
1057
1058 - The hostname in HOST:PATH or HOST::PATH may now be an IPv6 literal
1059 enclosed in '[' and ']' (e.g. "[::1]"). (We already allowed IPv6
1060 literals in the rsync://HOST:PORT/PATH format.)
1061
1062 - When rsync recurses to build the file list, it no longer keeps open
1063 one or more directory handles from the dir's parent dirs.
1064
1065 - When building under windows, the default for --daemon is now to
1066 avoid detaching, requiring the new --detach option to force rsync
1067 to detach.
1068
1069 - The --dry-run option can now be combined with either --write-batch or
1070 --read-batch, allowing you to run a do-nothing test command to see
1071 what would happen without --dry-run.
1072
1073 - The daemon's "read only" config item now sets an internal read_only
1074 variable that makes extra sure that no write/delete calls on the
1076
1077 - The log-format % escapes can now have a numeric field width in
1078 between the % and the escape letter (e.g. "%-40n %08p").
1079
1080 - Improved the option descriptions in the --help text.
1081
1082 SUPPORT FILES:
1083
1084 - Added atomic-rsync to the support dir: a perl script that will
1085 transfer some files using rsync, and then move the updated files into
1086 place all at once at the end of the transfer. Only works when
1087 pulling, and uses --link-dest and a parallel hierarchy of files to
1088 effect its update.
1089
1090 - Added mnt-excl to the support dir: a perl script that takes the
1091 /proc/mounts file and translates it into a set of excludes that will
1092 exclude all mount points (even mapped mounts to the same disk). The
1093 excludes are made relative to the specified source dir and properly
1094 anchored.
1095
1096 - Added savetransfer.c to the support dir: a C program that can make
1097 a copy of all the data that flows over the wire. This lets you test
1098 for data corruption (by saving the data on both the sending side and
1099 the receiving side) and provides one way to debug a protocol error.
1100
1101 - Added rrsync to the support dir: this is an updated version of Joe
1102 Smith's restricted rsync perl script. This helps to ensure that only
1103 certain rsync commands can be run by an ssh invocation.
1104
1105 INTERNAL:
1106
1107 - Added better checking of the checksum-header values that come over
1108 the socket.
1109
1110 - Merged a variety of file-deleting functions into a single function so
1111 that it is easier to maintain.
1112
1113 - Improved the type of some variables (particularly blocksize vars) for
1114 consistency and proper size.
1115
1116 - Got rid of the uint64 type (which we didn't need).
1117
1118 - Use a slightly more compatible set of core #include directives.
1119
1120 - Defined int32 in a way that ensures that the build dies if we can't
1121 find a variable with at least 32 bits.
1122
1123 PROTOCOL DIFFERENCES FOR VERSION 29:
1124
1125 - A 16-bit flag-word is transmitted after every file-list index. This
1126 indicates what is changing between the sender and the receiver. The
1127 generator now transmits an index and a flag-word to indicate when
1129 which makes the outputting of the information more consistent and
1130 less prone to screen corruption (because the local receiver/sender is
1131 now outputting all the file-change info messages).
1132
1133 - If a file is being hard-linked, the ITEM_XNAME_FOLLOWS bit is enabled
1134 in the flag-word and the name of the file that was linked immediately
1135 follows in vstring format (see below).
1136
1137 - If a file is being transferred with an alternate-basis file, the
1138 ITEM_BASIS_TYPE_FOLLOWS bit is enabled in the flag-word and a single
1139 byte follows, indicating what type of basis file was chosen. If that
1140 indicates that a fuzzy-match was selected, the ITEM_XNAME_FOLLOWS bit
1141 is set in the flag-word and the name of the match in vstring format
1142 follows the basis byte. A vstring is a variable length string that
1143 has its size written prior to the string, and no terminating null.
1144 If the string is from 1-127 bytes, the length is a single byte. If
1145 it is from 128-32767 bytes, the length is written as ((len >> 8) |
1146 0x80) followed by (len % 0x100).
1147
1148 - The sending of exclude names is done using filter-rule syntax. This
1149 means that all names have a prefixed rule indicator, even excludes
1150 (which used to be sent as a bare pattern, when possible). The -C
1151 option will include the per-dir .cvsignore merge file in the list of
1152 filter rules so it is positioned correctly (unlike in some older
1153 transfer scenarios).
1154
1155 - Rsync sorts the filename list in a different way: it sorts the subdir
1156 names after the non-subdir names for each dir's contents, and it
1157 always puts a dir's contents immediately after the dir's name in the
1158 list. (Previously an item named "foo.txt" would sort in between
1159 directory "foo/" and "foo/bar".)
1160
1161 - When talking to a protocol 29 rsync daemon, a list-only request
1162 is able to note this before the options are sent over the wire and
1163 the new --list-only option is included in the options.
1164
1165 - When the --stats bytes are sent over the wire (or stored in a batch),
1166 they now include two elapsed-time values: one for how long it took to
1167 build the file-list, and one for how long it took to send it over the
1168 wire (each expressed in thousandths of a second).
1169
1170 - When --delete-excluded is specified with some filter rules (AKA
1171 excludes), a client sender will now initiate a send of the rules to
1172 the receiver (older protocols used to omit the sending of excludes in
1173 this situation since there were no receiver-specific rules that
1174 survived --delete-excluded back then). Note that, as with all the
1175 filter-list sending, only items that are significant to the other
1176 side will actually be sent over the wire, so the filter-rule list
1177 that is sent in this scenario is often empty.
1178
1179 - An index equal to the file-list count is sent as a keep-alive packet
1180 from the generator to the sender, which then forwards it on to the
1181 receiver. This normally invalid index is only a valid keep-alive
1182 packet if the 16-bit flag-word that follows it contains a single bit
1183 (ITEM_IS_NEW, which is normally an illegal flag to appear alone).
1184
1185 - A protocol-29 batch file includes a bit for the setting of the --dirs
1186 option and for the setting of the --compress option. Also, the shell
1187 script created by --write-batch will use the --filter option instead
1188 of --exclude-from to capture any filter rules.
1189
1190 BUILD CHANGES:
1191
1192 - Handle an operating system that use mkdev() in place of makedev().
1193
1194 - Improved configure to better handle cross-compiling.

1197NEWS for rsync 2.6.3 (30 Sep 2004)
1198Protocol: 28 (unchanged)
1199Changes since 2.6.2:
1200
1201 SECURITY FIXES:
1202
1203 - A bug in the sanitize_path routine (which affects a non-chrooted
1204 rsync daemon) could allow a user to craft a pathname that would get
1205 transformed into an absolute path for certain options (but not for
1206 file-transfer names). If you're running an rsync daemon with chroot
1208 rsync under is anything above "nobody".
1209
1210 OUTPUT CHANGES (ATTN: those using a script to parse the verbose output):
1211
1212 - Please note that the 2-line footer (output when verbose) now uses the
1214 you are not parsing the numeric values out of this footer, a script
1215 would be better off using the empty line prior to the footer as the
1216 indicator that the verbose output is over.
1217
1218 - The output from the --stats option was similarly affected to change
1220
1221 - Rsync ensures that a filename that contains a newline gets mentioned
1222 with each newline transformed into a question mark (which prevents a
1223 filename from causing an empty line to be output).
1224
1225 - The "backed up ..." message that is output when at least 2 --verbose
1226 options are specified is now the same both with and without the
1227 --backup-dir option.
1228
1229 BUG FIXES:
1230
1231 - Fixed a crash bug that might appear when --delete was used and
1232 multiple source directories were specified.
1233
1234 - Fixed a 32-bit truncation of the file length when generating the
1235 checksums.
1236
1237 - The --backup code no longer attempts to create some directories
1238 over and over again (generating warnings along the way).
1239
1240 - Fixed a bug in the reading of the secrets file (by the daemon) and
1241 the password file (by the client): the files no longer need to be
1242 terminated by a newline for their content to be read in.
1243
1244 - If a file has a read error on the sending side or the reconstructed
1245 data doesn't match the expected checksum (perhaps due to the basis
1246 file changing during the transfer), the receiver will no longer
1247 retain the resulting file unless the --partial option was specified.
1248 (Note: for the read-error detection to work, neither side can be
1249 older than 2.6.3 -- older receivers will always retain the file, and
1251 error.)
1252
1253 - If a file gets resent in a single transfer and the --backup option
1254 is enabled, rsync no longer performs a duplicate backup (it used to
1255 overwrite the original file in the backup area).
1256
1257 - Files specified in the daemon's "exclude" or "exclude from" config
1258 items are now excluded from being uploaded (assuming that the module
1260
1261 - Got rid of a potential hang in the receiver when near the end of a
1262 phase.
1263
1264 - When using --backup without a --backup-dir, rsync no longer preserves
1265 the modify time on directories. This avoids confusing NFS.
1266
1267 - When --copy-links (-L) is specified, we now output a separate error
1268 for a symlink that has no referent instead of claiming that a file
1269 "vanished".
1270
1271 - The --copy-links (-L) option no longer has the side-effect of telling
1273 option (mentioned below) for a way to specify that behavior.
1274
1275 - Error messages from the daemon server's option-parsing (such as
1276 refused options) are now successfully transferred back to the client
1277 (the server used to fail to send the message because the socket
1278 wasn't in the right state for the message to get through).
1279
1280 - Most transfer errors that occur during a daemon transfer are now
1281 returned to the user in addition to being logged (some messages are
1282 intended to be daemon-only and are not affected by this).
1283
1284 - Fixed a bug in the daemon authentication code when using one of the
1285 batch-processing options.
1286
1287 - We try to work around some buggy IPv6 implementations that fail to
1288 implement IPV6_V6ONLY. This should fix the "address in use" error
1289 that some daemons get when running on an OS with a buggy IPv6
1290 implementation. Also, if the new code gets this error, we might
1291 suggest that the user specify --ipv4 or --ipv6 (if we think it will
1292 help).
1293
1294 - When the remote rsync dies, make a better effort to recover any error
1295 messages it may have sent before dying (the local rsync used to just
1296 die with a socket-write error).
1297
1298 - When using --delete and a --backup-dir that contains files that are
1299 hard-linked to their destination equivalents, rsync now makes sure
1300 that removed files really get removed (avoids a really weird rename()
1301 behavior).
1302
1303 - Avoid a bogus run-time complaint about a lack of 64-bit integers when
1304 the int64 type is defined as an off_t and it actually has 64-bits.
1305
1306 - Added a configure check for open64() without mkstemp64() so that we
1307 can avoid using mkstemp() when such a combination is encountered.
1308 This bypasses a problem writing out large temp files on OSes such as
1309 AIX and HP-UX.
1310
1311 - Fixed an age-old crash problem with --read-batch on a local copy
1312 (rsync was improperly assuming --whole-file for the local copy).
1313
1314 - When --dry-run (-n) is used and the destination directory does not
1315 exist, rsync now produces a correct report of files that would be
1316 sent instead of dying with a chdir() error.
1317
1318 - Fixed a bug that could cause a slow-to-connect rsync daemon to die
1319 with an error instead of waiting for the connection to finish.
1320
1321 - Fixed an ssh interaction that could cause output to be lost when the
1322 user chose to combine the output of rsync's stdout and stderr (e.g.
1323 using the "2>&1").
1324
920240a6
WD
1325 - Fixed an option-parsing bug when --files-from got passed to a daemon.
1326

1327 ENHANCEMENTS:
1328
1329 - Added the --partial-dir=DIR option that lets you specify where to
1330 (temporarily) put a partially transferred file (instead of over-
1331 writing the destination file). E.g. --partial-dir=.rsync-partial
1332 Also added support for the RSYNC_PARTIAL_DIR environment variable
1333 that, when found, transforms a regular --partial option (such as
1334 the convenient -P option) into one that also specifies a directory.
1335
1337 onto another partition on the receiving side and have rsync treat it
1338 as matching a normal directory from the sender.
1339
1340 - Added the --inplace option that tells rsync to write each destination
1341 file without using a temporary file. The matching of existing data
1342 in the destination file can be severely limited by this, but there
1343 are also cases where this is more efficient (such as appending data).
1344 Use only when needed (see the man page for more details).
1345
1346 - Added the "write only" option for the daemon's config file.
1347
1348 - Added long-option names for -4 and -6 (namely --ipv4 and --ipv6)
1349 and documented all these options in the man page.
1350
1351 - Improved the handling of the --bwlimit option so that it's less
1352 bursty, more accurate, and works properly over a larger range of
1353 values.
1354
1355 - The rsync daemon-over-ssh code now looks for SSH_CONNECTION and
1356 SSH2_CLIENT in addition to SSH_CLIENT to figure out the IP address.
1357
1359
1360 - Batch writing/reading has a brand-new implementation that is simpler,
1361 fixes a few weird problems with the old code (such as no longer
1362 sprinkling the batch files into different dirs or even onto different
1363 systems), and is much less intrusive into the code (making it easier
1364 to maintain for the future). The new code generates just one data
1365 file instead of three, which makes it possible to read the batch on
1366 stdin via a remote shell. Also, the old requirement of forcing the
1367 same fixed checksum-seed for all batch processing has been removed.
1368
1369 - If an rsync daemon has a module set with "list = no" (which hides its
1370 presence in the list of available modules), a user that fails to
1371 authenticate gets the same "unknown module" error that they would get
1372 if the module were actually unknown (while still logging the real
1373 error to the daemon's log file). This prevents fishing for module
1374 names.
1375
1376 - The daemon's "refuse options" config item now allows you to match
1377 option names using wildcards and/or the single-letter option names.
1378
1379 - Each transferred file now gets its permissions and modified-time
1380 updated before the temp-file gets moved into place. Previously, the
1381 finished file would have a very brief window where its permissions
1382 disallowed all group and world access.
1383
1384 - Added the ability to parse a literal IPv6 address in an "rsync:" URL
1385 (e.g. rsync://[2001:638:500:101::21]:873/module/dir).
1386
1387 - The daemon's wildcard expanding code can now handle more than 1000
1388 filenames (it's now limited by memory instead of having a hard-wired
1389 limit).
1390
1391 INTERNAL:
1392
1393 - Some cleanup in the exclude code has saved some per-exclude memory
1394 and made the code easier to maintain.
1395
1396 - Improved the argv-overflow checking for a remote command that has a
1397 lot of args.
1398
1399 - Use rsyserr() in the various places that were still calling rprintf()
1400 with strerror() as an arg.
1401
1402 - If an rsync daemon is listening on multiple sockets (to handle both
1403 IPv4 and IPv6 to a single port), we now close all the unneeded file
1404 handles after we accept a connection (we used to close just one of
1405 them).
1406
1407 - Optimized the handling of larger block sizes (rsync used to slow to a
1408 crawl if the block size got too large).
1409
1410 - Optimized away a loop in hash_search().
1411
1412 - Some improvements to the sanitize_path() and clean_fname() functions
1413 makes them more efficient and produce better results (while still
1414 being compatible with the file-name cleaning that gets done on both
1415 sides when sending the file-list).
1416
1417 - Got rid of alloc_sanitize_path() after adding a destination-buffer
1418 arg to sanitize_path() made it possible to put all the former's
1419 functionality into the latter.
1420
1421 - The file-list that is output when at least 4 verbose options are
1422 specified reports the uid value on the sender even when rsync is
1423 not running as root (since we might be sending to a root receiver).
1424
1425 BUILD CHANGES:
1426
1427 - Added a "gen" target to rebuild most of the generated files,
1428 including configure, config.h.in, the man pages, and proto.h.
1429
1430 - If "make proto" doesn't find some changes in the prototypes, the
1431 proto.h file is left untouched (its time-stamp used to always be
1432 updated).
1433
1434 - The variable $STRIP (that is optionally set by the install-strip 1435 target's rule) was changed to$INSTALL_STRIP because some systems
1436 have \$STRIP already set in the environment.
1437
1438 - Fixed a build problem when SUPPORT_HARD_LINKS isn't defined.
1439
1440 - When cross-compiling, the gettimeofday() function is now assumed to
1441 be a modern version that takes two-args (since we can't test it).
1442
1443 DEVELOPER RELATED:
1444
1445 - The scripts in the testsuite dir were cleaned up a bit and a few
1447
1448 - Some new diffs were added to the patches dir, and some accepted
1449 ones were removed.

1452NEWS for rsync 2.6.2 (30 Apr 2004)
1453Protocol: 28 (unchanged)
1454Changes since 2.6.1:
1455
1456 BUG FIXES:
1457
1458 - Fixed a major bug in the sorting of the filenames when --relative
1459 is used for some sources (just sources such as "/" and "/*" were
1460 affected). This fix ensures that we ask for the right file-list
1461 item when requesting changes from the sender.
1462
1463 - Rsync now checks the return value of the close() function to
1464 better report disk-full problems on an NFS file system.
1465
1466 - Restored the old daemon-server behavior of logging error messages
1467 rather than returning them to the user. (A better long-term fix
1468 will be sought in the future.)
1469
1470 - An obscure uninitialized-variable bug was fixed in the uid/gid
1471 code. (This bug probably had no ill effects.)
1472
1473 BUILD CHANGES:
1474
1475 - Got rid of the configure check for sys/sysctl.h (it wasn't used
1476 and was causing a problem on some systems). Also improved the
1477 broken-largefile-locking test to try to avoid failure due to an
1478 NFS build-dir.
1479
1480 - Fixed a compile problem on systems that don't define
1481 AI_NUMERICHOST.
1482
1483 - Fixed a compile problem in the popt source for compilers that
1484 don't support __attribute__.
1485
1486 DEVELOPER RELATED:
1487
1488 - Improved the testsuite's "merge" test to work on OSF1.
1489
1490 - Two new diffs were added to the patches dir.

1493NEWS for rsync 2.6.1 (26 Apr 2004)
1494Protocol: 28 (changed)
1495Changes since 2.6.0:
1496
1497 SECURITY FIXES:
1498
1499 - Paths sent to an rsync daemon are more thoroughly sanitized when
1500 chroot is not used. If you're running a non-read-only rsync
1502 user privs you run rsync under is anything above "nobody".
1503
1504 ENHANCEMENTS:
1505
1506 - Lower memory use, more optimal transfer of data over the socket,
1507 and lower CPU usage (see the INTERNAL section for details).
1508
1509 - The RSYNC_PROXY environment variable can now contain a
1510 "USER:PASS@" prefix before the "HOST:PORT" information.
1511 (Bardur Arantsson)
1512
1513 - The --progress output now mentions how far along in the transfer
1514 we are, including both a count of files transferred and a
1515 percentage of the total file-count that we've processed. It also
1516 shows better current-rate-of-transfer and remaining-transfer-time
1517 values.
1518
1519 - Documentation changes now attempt to describe some often mis-
1520 understood features more clearly.
1521
1522 BUG FIXES:
1523
1524 - When -x (--one-file-system) is combined with -L (--copy-links) or
1526 referent file is on a different filesystem.
1527
1528 - The --link-dest code now works properly for a non-root user when
1529 (1) the UIDs of the source and destination differ and -o was
1530 specified, or (2) when the group of the source can't be used on
1531 the destination and -g was specified.
1532
1533 - Fixed a bug in the handling of -H (hard-links) that might cause
1534 the expanded PATH/NAME value of the current item to get
1535 overwritten (due to an expanded-name caching bug).
1536
1537 - We now reset the "new data has been sent" flag at the start of
1538 each file we send. This makes sure that an interrupted transfer
1539 with the --partial option set doesn't keep a shorter temp file
10a1a3f5 1540 than the current basis file when no new data has been transferred
c7be6dec
WD
1541 over the wire for that file.
1542
1543 - Fixed a byte-order problem in --batch-mode on big-endian machines.
1544 (Jay Fenlason)
1545
1546 - When using --cvs-exclude, the exclude items we get from a
1547 per-directory's .cvsignore file once again only affect that one
1548 directory (not all following directories too). The items are also
1549 now properly word-split and parsed without any +/- prefix parsing.
1550
1551 - When specifying the USER@HOST: prefix for a file, the USER part
1552 can now contain an '@', if needed (i.e. the last '@' is used to
1553 find the HOST, not the first).
1554
1555 - Fixed some bugs in the handling of group IDs for non-root users:
1556 (1) It properly handles a group that the sender didn't have a name
1557 for (it would previously skip changing the group on any files in
1558 that group). (2) If --numeric-ids is used, rsync no longer
1559 attempts to set groups that the user doesn't have the permission
1560 to set.
1561
1562 - Fixed the "refuse options" setting in the rsyncd.conf file.
1563
1564 - Improved the -x (--one-file-system) flag's handling of any mount-
1565 point directories we encounter. It is both more optimal (in that
1566 it no longer does a useless scan of the contents of the mount-
1567 point dirs) and also fixes a bug where a remapped mount of the
1568 original filesystem could get discovered in a subdir we should be
1569 ignoring.
1570
1571 - Rsync no longer discards a double-slash at the start of a filename
1572 when trying to open the file. It also no longer constructs names
1573 that start with a double slash (unless the user supplied them).
1574
1575 - Path-specifying options to a daemon should now work the same with
1576 or without chroot turned on. Previously, such a option (such as
1577 --link-dest) would get its absolute path munged into a relative
1578 one if chroot was not on, making that setting fairly useless.
1579 Rsync now transforms the path into one that is based on the
1580 module's base dir when chroot is not enabled.
1581
1582 - Fixed a compatibility problem interacting with older rsync
1583 versions that might send us an empty --suffix value without
1584 telling us that --backup-dir was specified.
1585
1586 - The "hosts allow" option for a daemon-over-remote-shell process
1587 now has improved support for IPv6 addresses and a fix for systems
1588 that have a length field in their socket structs.
1589
1590 - Fixed the ability to request an empty backup --suffix when sending
1591 files to an rsync daemon.
1592

1593 - Fixed an option-parsing bug when --files-from was sent to a server
1594 sender.

1596 INTERNAL:
1597
1598 - Most of the I/O is now buffered, which results in a pretty large
1599 speedup when running under MS Windows. (Craig Barratt)
1600
1601 - Optimizations to the name-handling/comparing code have made some
1602 significant reductions in user-CPU time for large file sets.
1603
1604 - Some cleanup of the variable types make the code more consistent.
1605
1606 - Reduced memory requirements of hard link preservation.
1607 (J.W. Schultz)
1608
1609 - Implemented a new algorithm for hard-link handling that speeds up
1610 the code significantly. (J.W. Schultz and Wayne Davison)
1611
1612 - The --hard-link option now uses the first existing file in the
1613 group of linked files as the basis for the transfer. This
1614 prevents the sub-optimal transfer of a file's data when a new
1615 hardlink is added on the sending side and it sorts alphabetically
1616 earlier in the list than the files that are already present on the
1617 receiving side.
1618
1619 - Dropped support for protocol versions less than 20 (2.3.0 released
1620 15 Mar 1999) and activated warnings for protocols less than 25
1621 (2.5.0 released 23 Aug 2001). (Wayne Davison and J.W. Schultz,
1622 severally)
1623
1624 - More optimal data transmission for --hard-links (protocol 28).
1625
1626 - More optimal data transmission for --checksum (protocol 28).
1627
1628 - Less memory is used when --checksum is specified.
1629
1630 - Less memory is used in the file list (a per-file savings).
1631
1632 - The generator is now better about not modifying the file list
1633 during the transfer in order to avoid a copy-on-write memory
1634 bifurcation (on systems where fork() uses shared memory).
1635 Previously, rsync's shared memory would slowly become unshared,
1636 resulting in real memory usage nearly doubling on the receiving
1637 side by the end of the transfer. Now, as long as permissions
1638 are being preserved, the shared memory should remain that way
1639 for the entire transfer.
1640
1641 - Changed hardlink info and file_struct + strings to use allocation
1642 pools. This reduces memory use for large file-sets and permits
1643 freeing memory to the OS. (J.W. Schultz)
1644
1645 - The 2 pipes used between the receiver and generator processes
1646 (which are forked on the same machine) were reduced to 1 pipe and
1647 the protocol improved so that (1) it is now impossible to have the
1648 "redo" pipe fill up and hang rsync, and (2) trailing messages from
1649 the receiver don't get lost on their way through the generator
1650 over to the sender (which mainly affected hard-link messages and
1651 verbose --stats output).
1652
1653 - Improved the internal uid/gid code to be more portable and a
1654 little more optimized.
1655
1656 - The device numbers sent when using --devices are now sent as
1657 separate major/minor values with 32-bit accuracy (protocol 28).
1658 Previously, the copied devices were sent as a single 32-bit
1659 number. This will make inter-operation of 64-bit binaries more
1660 compatible with their 32-bit brethren (with both ends of the
1661 connection are using protocol 28). Note that optimizations in the
1662 binary protocol for sending the device numbers often results in
1663 fewer bytes being used than before, even though more precision is
1664 now available.
1665
1666 - Some cleanup of the exclude/include structures and its code made
1667 things clearer (internally), simpler, and more efficient.
1668
1669 - The reading & writing of the file-list in batch-mode is now
1670 handled by the same code that sends & receives the list over the
1671 wire. This makes it much easier to maintain. (Note that the
1672 batch code is still considered to be experimental.)
1673
1674 BUILD CHANGES:
1675
1676 - The configure script now accepts --with-rsyncd-conf=PATH to
1677 override the default value of the /etc/rsyncd.conf file.
1678
1679 - Fixed configure bug when running "./configure --disable-ipv6".
1680
1681 - Fixed compilation problem on Tru64 Unix (having to do with
1683
1684 DEVELOPER RELATED:
1685
1686 - Fixed "make test" bug when build dir is not the source dir.
1687
1688 - Added a couple extra diffs in the "patches" dir, removed the ones
1689 that got applied, and rebuilt the rest.

1692NEWS for rsync 2.6.0 (1 Jan 2004)
1693Protocol: 27 (changed)
1694Changes since 2.5.7:
1695
1696 ENHANCEMENTS:
1697
1698 * "ssh" is now the default remote shell for rsync. If you want to
1699 change this, configure like this: "./configure --with-rsh=rsh".
1700
1701 * Added --files-from, --no-relative, --no-implied-dirs, and --from0.
1702 Note that --from0 affects the line-ending character for all the
1703 files read by the --*-from options. (Wayne Davison)
1704
1705 * Length of csum2 is now per-file starting with protocol version
1706 27. (J.W. Schultz)
1707
1708 * Per-file dynamic block size is now sqrt(file length). The
1709 per-file checksum size is determined according to an algorithm
1710 provided by Donovan Baarda which reduces the probability of rsync
1711 algorithm corrupting data and falling back using the whole md4
1712 checksums. (J.W. Schultz, Donovan Baarda)
1713
1714 * The --stats option no longer includes the (debug) malloc summary
1715 unless the verbose option was specified at least twice.
1716
1717 * Added a new error/warning code for when files vanish from the
1718 sending side. Made vanished source files not interfere with the
1719 file-deletion pass when --delete-after was specified.
1720
1721 * Various trailing-info sections are now preceded by a newline.
1722
1723 BUG FIXES:
1724
1725 * Fixed several exclude/include matching bugs when using wild-cards.
1726 This has a several user-visible effects, all of which make the
1727 matching more consistent and intuitive. This should hopefully not
1728 cause anyone problems since it makes the matching work more like
1729 what people are expecting. (Wayne Davison)
1730
1731 - A pattern with a "**" no longer causes a "*" to match slashes.
1732 For example, with "/*/foo/**", "foo" must be 2 levels deep.
1733 [If your string has BOTH "*" and "**" wildcards, changing the
1734 "*" wildcards to "**" will provide the old behavior in all
1735 versions.]
1736
1737 - "**/foo" now matches at the base of the transfer (like /foo
1738 does). [Use "/**/foo" to get the old behavior in all versions.]
1739
1740 - A non-anchored wildcard term floats to match beyond the base of
1741 the transfer. E.g. "CVS/R*" matches at the end of the path,
1742 just like the non-wildcard term "CVS/Root" does. [Use "/CVS/R*"
1743 to get the old behavior in all versions.]
1744
1745 - Including a "**" in the match term causes it to be matched
1746 against the entire path, not just the name portion, even if
1747 there aren't any interior slashes in the term. E.g. "foo**bar"
1748 would exclude "/path/foo-bar" (just like before) as well as
1749 "/foo-path/baz-bar" (unlike before). [Use "foo*bar" to get the
1750 old behavior in all versions.]
1751
1752 * The exclude list specified in the daemon's config file is now
1753 properly applied to the pulled items no matter how deep the
1754 user's file-args are in the source tree. (Wayne Davison)
1755
1756 * For protocol version >= 27, mdfour_tail() is called when the
1757 block size (including checksum_seed) is a multiple of 64.
1758 Previously it was not called, giving the wrong MD4 checksum.
1759 (Craig Barratt)
1760
1761 * For protocol version >= 27, a 64 bit bit counter is used in
1762 mdfour.c as required by the RFC. Previously only a 32 bit bit
1763 counter was used, causing incorrect MD4 file checksums for
1764 file sizes >= 512MB - 4. (Craig Barratt)
1765
1766 * Fixed a crash bug when interacting with older rsync versions and
1767 multiple files of the same name are destined for the same dir.
1768 (Wayne Davison)
1769
1770 * Keep tmp names from overflowing MAXPATHLEN.
1771
1772 * Make --link-dest honor the absence of -p, -o, and -g.
1773
1774 * Made rsync treat a trailing slash in the destination in a more
1775 consistent manner.
1776
1777 * Fixed file I/O error detection. (John Van Essen)
1778
1779 * Fixed bogus "malformed address {hostname}" message in rsyncd log
1780 when checking IP address against hostnames from "hosts allow"
1781 and "hosts deny" parameters in config file.
1782
1783 * Print heap statistics when verbose >= 2 instead of when >= 1.
1784
1785 * Fixed a compression (-z) bug when syncing a mostly-matching file
1786 that contains already-compressed data. (Yasuoka Masahiko and
1787 Wayne Davison)
1788
1789 * Fixed a bug in the --backup code that could cause deleted files
1790 to not get backed up.
1791
1792 * When the backup code makes new directories, create them with mode
1793 0700 instead of 0755 (since the directory permissions in the
1794 backup tree are not yet copied from the main tree).
1795
1796 * Call setgroups() in a more portable manner.
1797
1798 * Improved file-related error messages to better indicate exactly
1799 what pathname failed. (Wayne Davison)
1800
1801 * Fixed some bugs in the handling of --delete and --exclude when
1802 using the --relative (-R) option. (Wayne Davison)
1803
1804 * Fixed bug that prevented regular files from replacing
1805 special files and caused a directory in --link-dest or
1806 --compare-dest to block the creation of a file with the
1807 same path. A directory still cannot be replaced by a
1808 regular file unless --delete specified. (J.W. Schultz)
1809
1810 * Detect and report when open or opendir succeed but read and
1811 readdir fail caused by network filesystem issues and truncated
1812 files. (David Norwood, Michael Brown, J.W. Schultz)
1813
1814 * Added a fix that should give ssh time to restore the tty settings
1815 if the user presses Ctrl-C at an ssh password prompt.
1816
1817 INTERNAL:
1818
1819 * Eliminated vestigial support for old versions that we stopped
1820 supporting. (J.W. Schultz)
1821
1822 * Simplified some of the option-parsing code. (Wayne Davison)
1823
1824 * Some cleanup made to the exclude code, as well as some new
1826
1827 * Changed the protocol-version code so that it can interact at a
1828 lower protocol level than the maximum supported by both sides.
1829 Added an undocumented option, --protocol=N, to force the value
1830 we advertise to the other side (primarily for testing purposes).

1888 L. Allen, Martin Pool)
1889
1890 * Generate each file's rolling-checksum data as we send it, not
1891 in a separate (memory-eating) pass before hand. This prevents
1892 timeout errors on really large files. (Stefan Nehlsen)
1893

2027
2028 ENHANCEMENTS:
2029
2030 * Merge in changes from zlib 1.1.2 to zlib 1.1.3. (Note that
2031 rsync still uses a custom version of zlib; you can not just link
2032 against a system library. See zlib/README.rsync)

2034 * Command to initiate connections is only shown with -vv, rather
2035 than -v as in 2.5.2. Output from plain -v is more similar to
2036 what was historically used so as not to break scripts that try
2037 to parse the output.
2038
2039 * Added --no-whole-file and --no-blocking-io options (Dave Dykstra)
2040
2042 and added documentation in the man page (Jos Backus)
2043
2044 * If the daemon is unable to fork a child to accept a connection,
2045 print an error message. (Colin Walters)

2051
2052 SECURITY FIXES:
2053
2054 * Signedness security patch from Sebastian Krahmer
2055 <krahmer@suse.de> -- in some cases we were not sufficiently
2057
2058 BUG FIXES:
2059
2060 * Fix possible string mangling in log files.
2061
2062 * Fix for setting local address of outgoing sockets.
2063
2064 * Better handling of hardlinks and devices on platforms with
2065 64-bit dev_t or ino_t.
2066
2067 * Name resolution on machines supporting IPv6 is improved.
2068
2069 * Fix for device nodes. (dann frazier) (Debian #129135)
2070
2071 ENHANCEMENTS:
2072
2073 * With -v, rsync now shows the command used to initiate an ssh/rsh
2074 connection.
2075
2076 * --statistics now shows memory heap usage on platforms that
276877cf 2077 support mallinfo().
97efa5c3
MP
2078
2079 * "The Ted T'so school of program optimization": make progress
2080 visible and people will think it's faster. (With --progress,
2081 rsync will show you how many files it has seen as it builds the
2082 file_list, giving some indication that it has not hung.)
2083
2084 * Improvements to batch mode support. This is still experimental
2085 but testing would be welcome. (Jos Backus)
276877cf 2086

2101 (YOSHIFUJI Hideaki, SUMIKAWA Munechika and Jun-ichiro "itojun"
2102 Hagino)
2103
2104 * Various fixes for IPv6 support. (Dave Dykstra)

2118 multiple of bytes/s) and estimated time to completion. (Rik
2119 Faith)
2120
499957d9 2121 * --no-detach option, required to run as a W32 service and also
276877cf

2122 useful when running on Unix under daemontools, AIX's SRC, or a
2123 debugger. (Max Bowsher, Jos Backus)

2131
2132 ANNOUNCEMENTS
2133
2134 * Martin Pool <mbp@samba.org> is now a co-maintainer.
2135
2136 NEW FEATURES
2137
2138 * Support for LSB-compliant packaging <http://www.linuxbase.org/>
2139
2140 * Shell wildcards are allowed in "auth users" lines.
2141
2142 * Merged UNC rsync+ patch to support creation of standalone patch
2143 sets. By Bert J. Dempsey and Debra Weiss, updated by Jos
2144 Backus. <http://www.ils.unc.edu/i2dsi/unc_rsync+.html>
2145
2146 * IPv6 support based on a patch from KAME.net, on systems
2147 including modern versions of Linux, Solaris, and HP-UX. Also
2148 includes IPv6 compatibility functions for old OSs by the
2149 Internet Software Consortium, Paul Vixie, the OpenSSH
2150 portability project, and OpenBSD.
2151
2152 ENHANCEMENTS
2153
2154 * Include/exclude cluestick: with -vv, print out whether files are
2155 included or excluded and why.
2156
2157 * Many error messages have more friendly explanations and more
2158 details.
2159
2160 * Manual page improvements plus scanty protocol documentation.
2161
2162 * When running as --daemon in the background and using a "log
2163 file" rsyncd.conf directive, close the log file every time it is
2164 open when going to sleep on the socket. This allows the log
2165 file to get cleaned out by another process.
2166
2167 * Change to using libpopt rather than getopt for processing
2168 options. This makes the code cleaner and the behaviour more
2169 consistent across platforms. popt is included and built if not
2170 installed on the platform.
2171
2172 * More details in --version, including note about whether 64-bit
2174
2175 * MD4 code may use less CPU cycles.
2176
2177 * Use mkstemp on systems where it is secure. If we use mktemp,
2178 explain that we do it in a secure way.
2179
2180 * --whole-file is the default when source and target are on the
2181 local machine.
2182
2183 BUG FIXES:
2184
2185 * Fix for various bugs causing rsync to hang.
2186
2187 * Attempt to fix Large File Summit support on AIX.
2188
2189 * Attempt to fix error handling lockup bug.
2190
2191 * Give a non-0 exit code if *any* of the files we have been asked
276877cf 2192 to transfer fail to transfer.

2193
2194 * For log messages containing ridiculously long strings that might
2195 overflow a buffer rsync no longer aborts, but rather prints an
2196 ellipsis at the end of the string. (Patch from Ed Santiago.)
2197
2198 PLATFORMS:
2199
2200 * Improved support for UNICOS (tested on Cray T3E and Cray SV1)
2201
2202 * autoconf2.52 (or later) is now required to rebuild the autoconf
276877cf 2203 scripts. It is not required to simply build rsync.
