1 | NEWS for rsync 2.6.9 (6 Nov 2006) |
2 | Protocol: 29 (unchanged) | |
3 | Changes 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. | |
2955529b WD |
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 | |
160 | consistent opening comments. | |

163 | NEWS for rsync 2.6.8 (22 Apr 2006) |
164 | Protocol: 29 (unchanged) | |
165 | Changes 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 | |
179 | that caused by a bad sector) would not advance the file's read-position | |
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 | |
190 | fifos) from being linked. | |
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). | |

232 | NEWS for rsync 2.6.7 (11 Mar 2006) |
233 | Protocol: 29 (unchanged) | |
234 | Changes 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 | |
241 | under the 'S' designation (e.g. "cS+++++++ path/fifo"). See also the | |
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) | |
252 | (e.g. it will output "foo\#134#789" when copying "foo\#789"). See also | |
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 | |
266 | read-error on the socket, it now signals the generator about this so that | |
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 | ||
270 | - Made hard-links work with symlinks and devices again. | |
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 | |
303 | handles hard-links (within the transfer) that had an up-to-date alternate | |
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 | |
386 | information about the transfer.) | |
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 | |
466 | that it receives. | |
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 | ||
488 | - Added the --copy-dirlinks option, a more limited version of --copy-links. | |
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. | |

553 | NEWS for rsync 2.6.6 (28 Jul 2005) |
554 | Protocol: 29 (unchanged) | |
555 | Changes 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 | |
569 | combined with --link-dest). | |
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 | |
591 | destination dir to tickle the bug in a recent version). | |
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. | |

619 | NEWS for rsync 2.6.5 (1 Jun 2005) |
620 | Protocol: 29 (unchanged) | |
621 | Changes 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 | ||
726 | - Added the --only-write-batch=FILE option that may be used (instead | |
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 | |
782 | rsync from being built without symlink or hard-link support. | |
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. | |

802 | NEWS for rsync 2.6.4 (30 March 2005) |
803 | Protocol: 29 (changed) | |
804 | Changes 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. | |
1ad6a7f6 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.) |
1ad6a7f6 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 | |
865 | warning about this at the end of the run and exit with a new error | |
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 | |
871 | readable symlinks that pointed to a non-existent file. | |
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.) | |
1ad6a7f6 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 |
1ad6a7f6 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 | ||
962 | - Added the --copy-dest option, which works like --link-dest except | |
963 | that it locally copies identical files instead of hard-linking them. | |
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 | |
982 | the patches dir.) Also added "address". The command-line options | |
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). | |
1ad6a7f6 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 | |
1075 | read-only side can succeed. | |
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 | |
1128 | dirs and symlinks have changed (instead of producing a message), | |
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. | |

1197 | NEWS for rsync 2.6.3 (30 Sep 2004) |
1198 | Protocol: 28 (unchanged) | |
1199 | Changes 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 | |
1207 | disabled, *please upgrade*, ESPECIALLY if the user privs you run | |
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 | |
1213 | term "sent" instead of "wrote" and "received" instead of "read". If | |
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 | |
1219 | "written" to "sent" and "read" to "received". | |
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 | |
1250 | older senders don't tell the receiver that the file had a read | |
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 | |
1259 | allows uploading at all) in addition to the old download exclusion. | |
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 | |
1272 | the receiving side to follow symlinks. See the --keep-dirlinks | |
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 | ||
ca39ebf9 WD |
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 | ||
1336 | - Added --keep-dirlinks (-K), which allows you to symlink a directory | |
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 | ||
1358 | - Added the --checksum-seed=N option for advanced users. | |
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 | |
1446 | new tests added. | |
1447 | ||
1448 | - Some new diffs were added to the patches dir, and some accepted | |
1449 | ones were removed. | |

1452 | NEWS for rsync 2.6.2 (30 Apr 2004) |
1453 | Protocol: 28 (unchanged) | |
1454 | Changes 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. | |
1491 | ||
1492 | \f | |
1493 | NEWS for rsync 2.6.1 (26 Apr 2004) | |
1494 | Protocol: 28 (changed) | |
1495 | Changes 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 | |
1501 | daemon with chroot disabled, *please upgrade*, ESPECIALLY if the | |
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 | |
1525 | --copy-unsafe-links, no symlinked files are skipped, even if the | |
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 | ||
920240a6 WD |
1593 | - Fixed an option-parsing bug when --files-from was sent to a server |
1594 | sender. | |
1595 | ||
c7be6dec WD |
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 | |
1682 | sockaddr.sa_len and sockaddr.sin_len). | |
1683 | ||
1684 | DEVELOPER RELATED: | |
1685 | ||
1686 | - Fixed "make test" bug when build dir is not the source dir. | |

1692 | NEWS for rsync 2.6.0 (1 Jan 2004) |
1693 | Protocol: 27 (changed) | |
1694 | Changes 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 | |
1825 | defines added to enhance readability. (Wayne Davison) | |
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). | |

1850 | * The --delete-after option now implies --delete. (Wayne Davison) | |
1851 | ||
1852 | * The --suffix option can now be used with --backup-dir. (Michael | |
1853 | Zimmerman) | |
1854 | ||
a923437b | 1855 | * Combining "::" syntax with the --rsh/-e option now uses the |
276877cf WD |
1856 | specified remote-shell as a transport to talk to a (newly-spawned) |
1857 | server-daemon. This allows someone to use daemon features, such | |
1858 | as modules, over a secure protocol, such as ssh. (JD Paul) | |
1859 | ||
1860 | * The rsync:// syntax for daemon connections is now accepted in the | |
1861 | destination field. | |
1862 | ||
1863 | * If the file name given to --include-from or --exclude-from is "-", | |
1864 | rsync will read from standard input. (J.W. Schultz) | |
1865 | ||
1866 | * New option --link-dest which is like --compare-dest except that | |
1867 | unchanged files are hard-linked in to the destination directory. | |
1868 | (J.W. Schultz) | |
1869 | ||

1871 | rsync run. (Eugene Chupriyanov and Bo Kersey) | |
1872 | ||
1873 | * Added .svn to --cvs-exclude list to support subversion. (Jon | |
1874 | Middleton) | |
1875 | ||
1876 | * Properly support IPv6 addresses in the rsyncd.conf "hosts allow" | |
1877 | and "hosts deny" fields. (Hideaki Yoshifuji) | |
1878 | ||
1879 | * Changed exclude file handling to permit DOS or MAC style line | |
1880 | terminations. (J.W. Schultz) | |
1881 | ||
1882 | * Ignore errors from chmod when -p/-a/--preserve-perms is not set. | |
1883 | (Dave Dykstra) | |
1884 | ||
1885 | BUG FIXES: | |
1886 | ||
1887 | * Fix "forward name lookup failed" errors on AIX 4.3.3. (John | |
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 | ||
1894 | * Fix compilation on Tru64. (Albert Chin, Zoong Pham) | |
1895 | ||
1896 | * Better handling of some client-server errors. (Martin Pool) | |
1897 | ||
1898 | * Fixed a crash that would occur when sending a list of files that | |
1899 | contains a duplicate name (if it sorts to the end of the file | |
1900 | list) and using --delete. (Wayne Davison) | |
1901 | ||
1902 | * Fixed the file-name duplicate-removal code when dealing with multiple | |
1903 | dups in a row. (Wayne Davison) | |
1904 | ||
1905 | * Fixed a bug that caused rsync to lose the exit status of its child | |
1906 | processes and sometimes return an exit code of 0 instead of showing | |
1907 | an error. (David R. Staples, Dave Dykstra) | |
1908 | ||
1909 | * Fixed bug in --copy-unsafe-links that caused it to be completely | |
1910 | broken. (Dave Dykstra) | |
1911 | ||
1912 | * Prevent infinite recursion in cleanup code under certain circumstances. | |

1916 | when --relative-paths/-R is set. (Craig Barratt) | |

2128 | NEWS for rsync 2.5.0 (30 Nov 2001) |
2129 | Protocol: 25 (changed) | |
2130 | Changes since 2.4.6: | |
d313ae7d MP |
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 | |
2173 | files, symlinks and hardlinks are supported. | |
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. |
d313ae7d MP |
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. |
