1 | NEWS for rsync 2.6.4 (30 March 2005) |
2 | Protocol: 29 (changed) | |
3 | Changes since 2.6.3: | |
4 | ||
5 | OUTPUT CHANGES: | |
6 | ||
7 | - When rsync deletes a directory and outputs a verbose message about | |
8 | it, it now appends a trailing slash to the name instead of (only | |
9 | sometimes) outputting a preceding "directory " string. | |
10 | ||
11 | - The --stats output will contain file-list time-statistics if both | |
12 | sides are 2.6.4, or if the local side is 2.6.4 and the files are | |
13 | being pushed (since the stats come from the sending side). | |
14 | (Requires protocol 29 for a pull.) | |
15 | ||
16 | - The "%o" (operation) log-format escape now has a third value (besides | |
17 | "send" and "recv"): "del." (with trailing dot to make it 4 chars). | |
18 | This changes the way deletions are logged in the daemon's log file. | |
19 | ||
20 | - When the --log-format option is combined with --verbose, rsync now | |
21 | avoids outputting the name of the file twice in most circumstances. | |
22 | As long as the --log-format item does not refer to any post-transfer | |
23 | items (such as %b or %c), the --log-format message is output prior to | |
24 | the transfer, so --verbose is now the equivalent of a --log-format of | |
25 | '%n%L' (which outputs the name and any link info). If the log output | |
26 | must occur after the transfer to be complete, the only time the name | |
27 | is also output prior to the transfer is when --progress was specified | |
28 | (so that the name will precede the progress stats, and the full | |
29 | --log-format output will come after). | |
30 | ||
31 | BUG FIXES: | |
32 | ||
33 | - Restore the list-clearing behavior of "!" in a .cvsignore file (2.6.3 | |
34 | was only treating it as a special token in an rsync include/exclude | |
35 | file). | |
36 | ||
37 | - The combination of --verbose and --dry-run now mentions the full list | |
38 | of changes that would be output without --dry-run. | |
39 | ||
40 | - Avoid a mkdir warning when removing a directory in the destination | |
41 | that already exists in the --backup-dir. | |
42 | ||
43 | - An OS that has a binary mode for its files (such as cygwin) needed | |
44 | setmode(fd, O_BINARY) called on the temp-file we opened with | |
45 | mkstemp(). (Fix derived from the cygwin's 2.6.3 rsync package.) | |
46 | ||
47 | - Fixed a potential hang when verbosity is high, the client side is | |
48 | the sender, and the file-list is large. | |
49 | ||
50 | - Fixed a potential protocol-corrupting bug where the generator could | |
51 | merge a message from the receiver into the middle of a multiplexed | |
52 | packet of data if only part of that data had been written out to the | |
53 | socket when the message from the generator arrived. | |
54 | ||
55 | - We now check if the OS doesn't support using mknod() for creating | |
56 | FIFOs and sockets, and compile-in some compatibility code using | |
57 | mkfifo() and socket() when necessary. | |
58 | ||
59 | - Fixed an off-by-one error in the handling of --max-delete=N. Also, | |
60 | if the --max-delete limit is exceeded during a run, we now output a | |
61 | warning about this at the end of the run and exit with a new error | |
62 | code (25). | |
63 | ||
64 | - One place in the code wasn't checking if fork() failed. | |
65 | ||
66 | - The "ignore nonreadable" daemon parameter used to erroneously affect | |
67 | readable symlinks that pointed to a non-existent file. | |
68 | ||
69 | - If the OS does not have lchown() and a chown() of a symlink will | |
70 | affect the referent of a symlink (as it should), we no longer try | |
71 | to set the user and group of a symlink. | |
72 | ||
73 | - The generator now properly runs the hard-link loop and the dir-time | |
74 | rewriting loop after we're sure that the redo phase is complete. | |
75 | ||
76 | - When --backup was specified with --partial-dir=DIR, where DIR is a | |
77 | relative path, the backup code was erroneously trying to backup a | |
78 | file that was put into the partial-dir. | |
79 | ||
80 | - If a file gets resent in a single transfer and the --backup option is | |
81 | enabled along with --inplace, rsync no longer performs a duplicate | |
82 | backup (it used to overwrite the first backup with the failed file). | |
83 | ||
84 | - One call to flush_write_file() was not being checked for an error. | |
85 | ||
86 | - The --no-relative option was not being sent from the client to a | |
87 | server sender. | |
88 | ||
89 | - If an rsync daemon specified "dont compress = ..." for a file and the | |
90 | client tried to specify --compress, the libz code was not handling a | |
91 | compression level of 0 properly. This could cause a transfer failure | |
92 | if the block-size for a file was large enough (e.g. rsync might have | |
93 | exited with an error for large files). | |
94 | ||
95 | - Fixed a bug that would sometimes surface when using --compress and | |
96 | sending a file with a block-size larger than 64K (either manually | |
97 | specified, or computed due to the file being really large). Prior | |
98 | versions of rsync would sometimes fail to decompress the data | |
99 | properly, and thus the transferred file would fail its verification. | |
100 | ||
101 | - If a daemon can't open the specified log file (i.e. syslog is not | |
102 | being used), die without crashing. We also output an error about | |
103 | the failure on stderr (which will only be seen if --no-detach was | |
104 | specified) and exit with a new error code (6). | |
105 | ||
106 | - A local transfer no longer duplicates all its include/exclude options | |
107 | (since the forked process already has a copy of the exclude list, | |
108 | there's no need to send them a set of duplicates). | |
109 | ||
110 | - When --progress is specified, the output of items that the generator | |
111 | is creating (e.g. dirs, symlinks) is now integrated into the progress | |
112 | output without overlapping it. (Requires protocol 29.) | |
113 | ||
114 | - When --timeout is specified, lulls that occur in the transfer while | |
115 | the generator is doing work that does not generate socket traffic | |
116 | (looking for changed files, deleting files, doing directory-time | |
117 | touch-ups, etc.) will cause a new keep-alive packet to be sent that | |
118 | should keep the transfer going as long as the generator continues to | |
119 | make progress. (Requires protocol 29.) | |
120 | ||
121 | - The stat size of a device is not added to the total file size of the | |
122 | items in the transfer (the size might be undefined on some OSes). | |
123 | ||
124 | - Fixed a problem with refused-option messages sometimes not making it | |
125 | back to the client side when a remote --files-from was in effect and | |
126 | the daemon was the receiver. | |
127 | ||
128 | - The --compare-dest option was not updating a file that differred in | |
129 | (the preserved) attributes from the version in the compare-dest DIR. | |
130 | ||
131 | - When rsync is copying files into a write-protected directory, fixed | |
132 | the change-report output for the directory so that we don't report | |
133 | an identical directory as changed. | |
134 | ||
135 | ENHANCEMENTS: | |
136 | ||
137 | - Rsync now supports popt's option aliases, which means that you can | |
138 | use /etc/popt and/or ~/.popt to create your own option aliases. | |
139 | ||
140 | - Added the --delete-during (--del) option which will delete files | |
141 | from the receiving side incrementally as each directory in the | |
142 | transfer is being processed. This makes it more efficient than the | |
143 | default, before-the-transfer behavior, which is now also available as | |
144 | --delete-before (and is still the default --delete-WHEN option that | |
145 | will be chosen if --delete or --delete-excluded is specified without | |
146 | a --delete-WHEN choice). All the --del* options infer --delete, so | |
147 | an rsync daemon that refuses "delete" will still refuse to allow any | |
148 | file-deleting options (including the new --remove-sent-files option). | |
149 | ||
150 | - All the --delete-WHEN options are now more memory efficient: | |
151 | Previously an duplicate set of file-list objects was created on the | |
152 | receiving side for the entire destination hierarchy. The new | |
153 | algorithm only creates one directory of objects at a time (for files | |
154 | inside the transfer). | |
155 | ||
156 | - Added the --copy-dest option, which works like --link-dest except | |
157 | that it locally copies identical files instead of hard-linking them. | |
158 | ||
159 | - Added support for specifying multiple --compare-dest, --copy-dest, or | |
160 | --link-dest options, but only of a single type. (Promoted from the | |
161 | patches dir and enhanced.) (Requires protocol 29.) | |
162 | ||
163 | - Added the --max-size option. (Promoted from the patches dir.) | |
164 | ||
165 | - The daemon-mode options are now separated from the normal rsync | |
166 | options so that they can't be mixed together. This makes it | |
167 | impossible to start a daemon that has improper default option values | |
168 | (which could cause problems when a client connects, such as hanging | |
169 | or crashing). | |
170 | ||
171 | - The --bwlimit option may now be used in combination with --daemon | |
172 | to specify both a default value for the daemon side and a value | |
173 | that cannot be exceeded by a user-specified --bwlimit option. | |
174 | ||
175 | - Added the "port" parameter to the rsyncd.conf file. (Promoted from | |
176 | the patches dir.) Also added "address". The command-line options | |
177 | take precedence over a config-file option, as expected. | |
178 | ||
179 | - In _exit_cleanup(): when we are exiting with a partially-received | |
180 | file, we now flush any data in the write-cache before closing the | |
181 | partial file. | |
182 | ||
183 | - The --inplace support was enhanced to work with --compare-dest, | |
184 | --link-dest, and (the new) --copy-dest options. (Requires protocol | |
185 | 29.) | |
186 | ||
187 | - Added the --dirs (-d) option for an easier way to copy directories | |
188 | without recursion. | |
189 | ||
190 | - Added the --list-only option, which is mainly a way for the client to | |
191 | put the server into listing mode without needing to resort to any | |
192 | internal option kluges (e.g. the age-old use of "-r --exclude="/*/*" | |
193 | for a non-recursive listing). This option is used automatically | |
194 | (behind the scenes) when a modern rsync speaks to a modern daemon, | |
195 | but may also be specified manually if you want to force the use of | |
196 | the --list-only option over a remote-shell connection. | |
197 | ||
198 | - Added the --omit-dir-times (-O) option, which will avoid updating | |
199 | the modified time for directories when --times was specified. This | |
200 | option will avoid an extra pass through the file-list at the end of | |
201 | the transfer (to tweak all the directory times), which may provide | |
202 | an appreciable speedup for a really large transfer. (Promoted from | |
203 | the patches dir.) | |
204 | ||
205 | - Added the --filter (-f) option and its helper option, -F. Filter | |
206 | rules are an extension to the existing include/exclude handling | |
207 | that also supports nested filter files as well as per-directory | |
208 | filter files (like .cvsignore, but with full filter-rule parsing). | |
209 | This new option was chosen in order to ensure that all existing | |
210 | include/exclude processing remained 100% compatible with older | |
211 | versions. Protocol 29 is needed for full filter-rule support, but | |
212 | backward-compatible rules work with earlier protocol versions. | |
213 | (Promoted from the patches dir and enhanced.) | |
214 | ||
215 | - Added the --delay-updates option that puts all updated files into | |
216 | a temporary directory (by default ".~tmp~", but settable via the | |
217 | --partial-dir=DIR option) until the end of the transfer. This | |
218 | makes the updates a little more atomic for a large transfer. | |
219 | ||
220 | - If rsync is put into the background, any output from --progress is | |
221 | reduced. | |
222 | ||
223 | - Documented the "max verbosity" setting for rsyncd.conf. (This | |
224 | setting was added a couple releases ago, but left undocumented.) | |
225 | ||
226 | - The sender and the generator now double-check the file-list index | |
227 | they are given, and refuse to try to do a file transfer on a | |
228 | non-file index (since that would indicate that something had gone | |
229 | very wrong). | |
230 | ||
231 | - Added the --itemize-changes (-i) option, which is a way to output a | |
232 | more detailed list of what files changed and in what way. The effect | |
233 | is the same as specifying a --log-format of "%i %n%L" (see both the | |
234 | rsync and rsyncd.conf manpages). Works with --dry-run too. | |
235 | ||
236 | - Added the --fuzzy (-y) option, which attempts to find a basis file | |
237 | for a file that is being created from scratch. The current algorithm | |
238 | only looks in the destination directory for the created file, but it | |
239 | does attempt to find a match based on size/mod-time (in case the file | |
240 | was renamed with no other changes) as well as based on a fuzzy | |
241 | name-matching algorithm. This option requires protocol 29 because it | |
242 | needs the new file-sorting order. (Promoted from patches dir and | |
243 | enhanced.) (Requires protocol 29.) | |
244 | ||
245 | - Added the --remove-sent-files option, which lets you move files | |
246 | between systems. | |
247 | ||
248 | - The hostname in HOST:PATH or HOST::PATH may now be an IPv6 literal | |
249 | enclosed in '[' and ']' (e.g. "[::1]"). (We already allowed IPv6 | |
250 | literals in the rsync://HOST:PORT/PATH format.) | |
251 | ||
252 | - When rsync recurses to build the file list, it no longer keeps open | |
253 | one or more directory handles from the dir's parent dirs. | |
254 | ||
255 | - When building under windows, the default for --daemon is now to | |
256 | avoid detaching, requiring the new --detach option to force rsync | |
257 | to detach. | |
258 | ||
259 | - The --dry-run option can now be combined with either --write-batch or | |
260 | --read-batch, allowing you to run a do-nothing test command to see | |
261 | what would happen without --dry-run. | |
262 | ||
263 | - The daemon's "read only" config item now sets an internal read_only | |
264 | variable that makes extra sure that no write/delete calls on the | |
265 | read-only side can succeed. | |
266 | ||
267 | - The log-format % escapes can now have a numeric field width in | |
268 | between the % and the escape letter (e.g. "%-40n %08p"). | |
269 | ||
270 | - Improved the option descriptions in the --help text. | |
271 | ||
272 | SUPPORT FILES: | |
273 | ||
274 | - Added atomic-rsync to the support dir: a perl script that will | |
275 | transfer some files using rsync, and then move the updated files into | |
276 | place all at once at the end of the transfer. Only works when | |
277 | pulling, and uses --link-dest and a parallel hierarchy of files to | |
278 | effect its update. | |
279 | ||
280 | - Added mnt-excl to the support dir: a perl script that takes the | |
281 | /proc/mounts file and translates it into a set of excludes that will | |
282 | exclude all mount points (even mapped mounts to the same disk). The | |
283 | excludes are made relative to the specified source dir and properly | |
284 | anchored. | |
285 | ||
286 | - Added savetransfer.c to the support dir: a C program that can make | |
287 | a copy of all the data that flows over the wire. This lets you test | |
288 | for data corruption (by saving the data on both the sending side and | |
289 | the receiving side) and provides one way to debug a protocol error. | |
290 | ||
291 | - Added rrsync to the support dir: this is an updated version of Joe | |
292 | Smith's restricted rsync perl script. This helps to ensure that only | |
293 | certain rsync commands can be run by an ssh invocation. | |
294 | ||
295 | INTERNAL: | |
296 | ||
297 | - Added better checking of the checksum-header values that come over | |
298 | the socket. | |
299 | ||
300 | - Merged a variety of file-deleting functions into a single function so | |
301 | that it is easier to maintain. | |
302 | ||
303 | - Improved the type of some variables (particularly blocksize vars) for | |
304 | consistency and proper size. | |
305 | ||
306 | - Got rid of the uint64 type (which we didn't need). | |
307 | ||
308 | - Use a slightly more compatible set of core #include directives. | |
309 | ||
310 | - Defined int32 in a way that ensures that the build dies if we can't | |
311 | find a variable with at least 32 bits. | |
312 | ||
313 | PROTOCOL DIFFERENCES FOR VERSION 29: | |
314 | ||
315 | - A 16-bit flag-word is transmitted after every file-list index. This | |
316 | indicates what is changing between the sender and the receiver. The | |
317 | generator now transmits an index and a flag-word to indicate when | |
318 | dirs and symlinks have changed (instead of producing a message), | |
319 | which makes the outputting of the information more consistent and | |
320 | less prone to screen corruption (because the local receiver/sender is | |
321 | now outputting all the file-change info messages). | |
322 | ||
323 | - If a file is being hard-linked, the ITEM_XNAME_FOLLOWS bit is enabled | |
324 | in the flag-word and the name of the file that was linked immediately | |
325 | follows in vstring format (see below). | |
326 | ||
327 | - If a file is being transferred with an alternate-basis file, the | |
328 | ITEM_BASIS_TYPE_FOLLOWS bit is enabled in the flag-word and a single | |
329 | byte follows, indicating what type of basis file was chosen. If that | |
330 | indicates that a fuzzy-match was selected, the ITEM_XNAME_FOLLOWS bit | |
331 | is set in the flag-word and the name of the match in vstring format | |
332 | follows the basis byte. A vstring is a variable length string that | |
333 | has its size written prior to the string, and no terminating null. | |
334 | If the string is from 1-127 bytes, the length is a single byte. If | |
335 | it is from 128-32767 bytes, the length is written as ((len >> 8) | | |
336 | 0x80) followed by (len % 0x100). | |
337 | ||
338 | - The sending of exclude names is done using filter-rule syntax. This | |
339 | means that all names have a prefixed rule indicator, even excludes | |
340 | (which used to be sent as a bare pattern, when possible). The -C | |
341 | option will include the per-dir .cvsignore merge file in the list of | |
342 | filter rules so it is positioned correctly (unlike in some older | |
343 | transfer scenarios). | |
344 | ||
345 | - Rsync sorts the filename list in a different way: it sorts the subdir | |
346 | names after the non-subdir names for each dir's contents, and it | |
347 | always puts a dir's contents immediately after the dir's name in the | |
348 | list. (Previously an item named "foo.txt" would sort in between | |
349 | directory "foo/" and "foo/bar".) | |
350 | ||
351 | - When talking to a protocol 29 rsync daemon, a list-only request | |
352 | is able to note this before the options are sent over the wire and | |
353 | the new --list-only option is included in the options. | |
354 | ||
355 | - When the --stats bytes are sent over the wire (or stored in a batch), | |
356 | they now include two elapsed-time values: one for how long it took to | |
357 | build the file-list, and one for how long it took to send it over the | |
358 | wire (each expressed in thousandths of a second). | |
359 | ||
360 | - When --delete-excluded is specified with some filter rules (AKA | |
361 | excludes), a client sender will now initiate a send of the rules to | |
362 | the receiver (older protocols used to omit the sending of excludes in | |
363 | this situation since there were no receiver-specific rules that | |
364 | survived --delete-excluded back then). Note that, as with all the | |
365 | filter-list sending, only items that are significant to the other | |
366 | side will actually be sent over the wire, so the filter-rule list | |
367 | that is sent in this scenario is often empty. | |
368 | ||
369 | - An index equal to the file-list count is sent as a keep-alive packet | |
370 | from the generator to the sender, which then forwards it on to the | |
371 | receiver. This normally invalid index is only a valid keep-alive | |
372 | packet if the 16-bit flag-word that follows it contains a single bit | |
373 | (ITEM_IS_NEW, which is normally an illegal flag to appear alone). | |
374 | ||
375 | - A protocol-29 batch file includes a bit for the setting of the --dirs | |
376 | option and for the setting of the --compress option. Also, the shell | |
377 | script created by --write-batch will use the --filter option instead | |
378 | of --exclude-from to capture any filter rules. | |
379 | ||
380 | BUILD CHANGES: | |
381 | ||
382 | - Handle an operating system that use mkdev() in place of makedev(). | |
383 | ||
384 | - Improved configure to better handle cross-compiling. | |

385 | NEWS for rsync 2.6.3 (30 Sep 2004) |
386 | Protocol: 28 (unchanged) | |
387 | Changes since 2.6.2: | |
388 | ||
389 | SECURITY FIXES: | |
390 | ||
391 | - A bug in the sanitize_path routine (which affects a non-chrooted | |
392 | rsync daemon) could allow a user to craft a pathname that would get | |
393 | transformed into an absolute path for certain options (but not for | |
394 | file-transfer names). If you're running an rsync daemon with chroot | |
395 | disabled, *please upgrade*, ESPECIALLY if the user privs you run | |
396 | rsync under is anything above "nobody". | |
397 | ||
398 | OUTPUT CHANGES (ATTN: those using a script to parse the verbose output): | |
399 | ||
400 | - Please note that the 2-line footer (output when verbose) now uses the | |
401 | term "sent" instead of "wrote" and "received" instead of "read". If | |
402 | you are not parsing the numeric values out of this footer, a script | |
403 | would be better off using the empty line prior to the footer as the | |
404 | indicator that the verbose output is over. | |
405 | ||
406 | - The output from the --stats option was similarly affected to change | |
407 | "written" to "sent" and "read" to "received". | |
408 | ||
409 | - Rsync ensures that a filename that contains a newline gets mentioned | |
410 | with each newline transformed into a question mark (which prevents a | |
411 | filename from causing an empty line to be output). | |
412 | ||
413 | - The "backed up ..." message that is output when at least 2 --verbose | |
414 | options are specified is now the same both with and without the | |
415 | --backup-dir option. | |
416 | ||
417 | BUG FIXES: | |
418 | ||
419 | - Fixed a crash bug that might appear when --delete was used and | |
420 | multiple source directories were specified. | |
421 | ||
422 | - Fixed a 32-bit truncation of the file length when generating the | |
423 | checksums. | |
424 | ||
425 | - The --backup code no longer attempts to create some directories | |
426 | over and over again (generating warnings along the way). | |
427 | ||
428 | - Fixed a bug in the reading of the secrets file (by the daemon) and | |
429 | the password file (by the client): the files no longer need to be | |
430 | terminated by a newline for their content to be read in. | |
431 | ||
432 | - If a file has a read error on the sending side or the reconstructed | |
433 | data doesn't match the expected checksum (perhaps due to the basis | |
434 | file changing during the transfer), the receiver will no longer | |
435 | retain the resulting file unless the --partial option was specified. | |
436 | (Note: for the read-error detection to work, neither side can be | |
437 | older than 2.6.3 -- older receivers will always retain the file, and | |
438 | older senders don't tell the receiver that the file had a read | |
439 | error.) | |
440 | ||
441 | - If a file gets resent in a single transfer and the --backup option | |
442 | is enabled, rsync no longer performs a duplicate backup (it used to | |
443 | overwrite the original file in the backup area). | |
444 | ||
445 | - Files specified in the daemon's "exclude" or "exclude from" config | |
446 | items are now excluded from being uploaded (assuming that the module | |
447 | allows uploading at all) in addition to the old download exclusion. | |
448 | ||
449 | - Got rid of a potential hang in the receiver when near the end of a | |
450 | phase. | |
451 | ||
452 | - When using --backup without a --backup-dir, rsync no longer preserves | |
453 | the modify time on directories. This avoids confusing NFS. | |
454 | ||
455 | - When --copy-links (-L) is specified, we now output a separate error | |
456 | for a symlink that has no referent instead of claiming that a file | |
457 | "vanished". | |
458 | ||
459 | - The --copy-links (-L) option no longer has the side-effect of telling | |
460 | the receiving side to follow symlinks. See the --keep-dirlinks | |
461 | option (mentioned below) for a way to specify that behavior. | |
462 | ||
463 | - Error messages from the daemon server's option-parsing (such as | |
464 | refused options) are now successfully transferred back to the client | |
465 | (the server used to fail to send the message because the socket | |
466 | wasn't in the right state for the message to get through). | |
467 | ||
468 | - Most transfer errors that occur during a daemon transfer are now | |
469 | returned to the user in addition to being logged (some messages are | |
470 | intended to be daemon-only and are not affected by this). | |
471 | ||
472 | - Fixed a bug in the daemon authentication code when using one of the | |
473 | batch-processing options. | |
474 | ||
475 | - We try to work around some buggy IPv6 implementations that fail to | |
476 | implement IPV6_V6ONLY. This should fix the "address in use" error | |
477 | that some daemons get when running on an OS with a buggy IPv6 | |
478 | implementation. Also, if the new code gets this error, we might | |
479 | suggest that the user specify --ipv4 or --ipv6 (if we think it will | |
480 | help). | |
481 | ||
482 | - When the remote rsync dies, make a better effort to recover any error | |
483 | messages it may have sent before dying (the local rsync used to just | |
484 | die with a socket-write error). | |
485 | ||
486 | - When using --delete and a --backup-dir that contains files that are | |
487 | hard-linked to their destination equivalents, rsync now makes sure | |
488 | that removed files really get removed (avoids a really weird rename() | |
489 | behavior). | |
490 | ||
491 | - Avoid a bogus run-time complaint about a lack of 64-bit integers when | |
492 | the int64 type is defined as an off_t and it actually has 64-bits. | |
493 | ||
494 | - Added a configure check for open64() without mkstemp64() so that we | |
495 | can avoid using mkstemp() when such a combination is encountered. | |
496 | This bypasses a problem writing out large temp files on OSes such as | |
497 | AIX and HP-UX. | |
498 | ||
499 | - Fixed an age-old crash problem with --read-batch on a local copy | |
500 | (rsync was improperly assuming --whole-file for the local copy). | |
501 | ||
502 | - When --dry-run (-n) is used and the destination directory does not | |
503 | exist, rsync now produces a correct report of files that would be | |
504 | sent instead of dying with a chdir() error. | |
505 | ||
506 | - Fixed a bug that could cause a slow-to-connect rsync daemon to die | |
507 | with an error instead of waiting for the connection to finish. | |
508 | ||
509 | - Fixed an ssh interaction that could cause output to be lost when the | |
510 | user chose to combine the output of rsync's stdout and stderr (e.g. | |
511 | using the "2>&1"). | |
512 | ||
513 | ENHANCEMENTS: | |
514 | ||
515 | - Added the --partial-dir=DIR option that lets you specify where to | |
516 | (temporarily) put a partially transferred file (instead of over- | |
517 | writing the destination file). E.g. --partial-dir=.rsync-partial | |
518 | Also added support for the RSYNC_PARTIAL_DIR environment variable | |
519 | that, when found, transforms a regular --partial option (such as | |
520 | the convenient -P option) into one that also specifies a directory. | |
521 | ||
522 | - Added --keep-dirlinks (-K), which allows you to symlink a directory | |
523 | onto another partition on the receiving side and have rsync treat it | |
524 | as matching a normal directory from the sender. | |
525 | ||
526 | - Added the --inplace option that tells rsync to write each destination | |
527 | file without using a temporary file. The matching of existing data | |
528 | in the destination file can be severely limited by this, but there | |
529 | are also cases where this is more efficient (such as appending data). | |
530 | Use only when needed (see the man page for more details). | |
531 | ||
532 | - Added the "write only" option for the daemon's config file. | |
533 | ||
534 | - Added long-option names for -4 and -6 (namely --ipv4 and --ipv6) | |
535 | and documented all these options in the man page. | |
536 | ||
537 | - Improved the handling of the --bwlimit option so that it's less | |
538 | bursty, more accurate, and works properly over a larger range of | |
539 | values. | |
540 | ||
541 | - The rsync daemon-over-ssh code now looks for SSH_CONNECTION and | |
542 | SSH2_CLIENT in addition to SSH_CLIENT to figure out the IP address. | |
543 | ||
544 | - Added the --checksum-seed=N option for advanced users. | |
545 | ||
546 | - Batch writing/reading has a brand-new implementation that is simpler, | |
547 | fixes a few weird problems with the old code (such as no longer | |
548 | sprinkling the batch files into different dirs or even onto different | |
549 | systems), and is much less intrusive into the code (making it easier | |
550 | to maintain for the future). The new code generates just one data | |
551 | file instead of three, which makes it possible to read the batch on | |
552 | stdin via a remote shell. Also, the old requirement of forcing the | |
553 | same fixed checksum-seed for all batch processing has been removed. | |
554 | ||
555 | - If an rsync daemon has a module set with "list = no" (which hides its | |
556 | presence in the list of available modules), a user that fails to | |
557 | authenticate gets the same "unknown module" error that they would get | |
558 | if the module were actually unknown (while still logging the real | |
559 | error to the daemon's log file). This prevents fishing for module | |
560 | names. | |
561 | ||
562 | - The daemon's "refuse options" config item now allows you to match | |
563 | option names using wildcards and/or the single-letter option names. | |
564 | ||
565 | - Each transferred file now gets its permissions and modified-time | |
566 | updated before the temp-file gets moved into place. Previously, the | |
567 | finished file would have a very brief window where its permissions | |
568 | disallowed all group and world access. | |
569 | ||
570 | - Added the ability to parse a literal IPv6 address in an "rsync:" URL | |
571 | (e.g. rsync://[2001:638:500:101::21]:873/module/dir). | |
572 | ||
573 | - The daemon's wildcard expanding code can now handle more than 1000 | |
574 | filenames (it's now limited by memory instead of having a hard-wired | |
575 | limit). | |
576 | ||
577 | INTERNAL: | |
578 | ||
579 | - Some cleanup in the exclude code has saved some per-exclude memory | |
580 | and made the code easier to maintain. | |
581 | ||
582 | - Improved the argv-overflow checking for a remote command that has a | |
583 | lot of args. | |
584 | ||
585 | - Use rsyserr() in the various places that were still calling rprintf() | |
586 | with strerror() as an arg. | |
587 | ||
588 | - If an rsync daemon is listening on multiple sockets (to handle both | |
589 | IPv4 and IPv6 to a single port), we now close all the unneeded file | |
590 | handles after we accept a connection (we used to close just one of | |
591 | them). | |
592 | ||
593 | - Optimized the handling of larger block sizes (rsync used to slow to a | |
594 | crawl if the block size got too large). | |
595 | ||
596 | - Optimized away a loop in hash_search(). | |
597 | ||
598 | - Some improvements to the sanitize_path() and clean_fname() functions | |
599 | makes them more efficient and produce better results (while still | |
600 | being compatible with the file-name cleaning that gets done on both | |
601 | sides when sending the file-list). | |
602 | ||
603 | - Got rid of alloc_sanitize_path() after adding a destination-buffer | |
604 | arg to sanitize_path() made it possible to put all the former's | |
605 | functionality into the latter. | |
606 | ||
607 | - The file-list that is output when at least 4 verbose options are | |
608 | specified reports the uid value on the sender even when rsync is | |
609 | not running as root (since we might be sending to a root receiver). | |
610 | ||
611 | BUILD CHANGES: | |
612 | ||
613 | - Added a "gen" target to rebuild most of the generated files, | |
614 | including configure, config.h.in, the man pages, and proto.h. | |
615 | ||
616 | - If "make proto" doesn't find some changes in the prototypes, the | |
617 | proto.h file is left untouched (its time-stamp used to always be | |
618 | updated). | |
619 | ||
620 | - The variable $STRIP (that is optionally set by the install-strip | |
621 | target's rule) was changed to $INSTALL_STRIP because some systems | |
622 | have $STRIP already set in the environment. | |
623 | ||
624 | - Fixed a build problem when SUPPORT_HARD_LINKS isn't defined. | |
625 | ||
626 | - When cross-compiling, the gettimeofday() function is now assumed to | |
627 | be a modern version that takes two-args (since we can't test it). | |
628 | ||
629 | DEVELOPER RELATED: | |
630 | ||
631 | - The scripts in the testsuite dir were cleaned up a bit and a few | |
632 | new tests added. | |
633 | ||
634 | - Some new diffs were added to the patches dir, and some accepted | |
635 | ones were removed. | |

638 | NEWS for rsync 2.6.2 (30 Apr 2004) |
639 | Protocol: 28 (unchanged) | |
640 | Changes since 2.6.1: | |
641 | ||
642 | BUG FIXES: | |
643 | ||
644 | - Fixed a major bug in the sorting of the filenames when --relative | |
645 | is used for some sources (just sources such as "/" and "/*" were | |
646 | affected). This fix ensures that we ask for the right file-list | |
647 | item when requesting changes from the sender. | |
648 | ||
649 | - Rsync now checks the return value of the close() function to | |
650 | better report disk-full problems on an NFS file system. | |
651 | ||
652 | - Restored the old daemon-server behavior of logging error messages | |
653 | rather than returning them to the user. (A better long-term fix | |
654 | will be sought in the future.) | |
655 | ||
656 | - An obscure uninitialized-variable bug was fixed in the uid/gid | |
657 | code. (This bug probably had no ill effects.) | |
658 | ||
659 | BUILD CHANGES: | |
660 | ||
661 | - Got rid of the configure check for sys/sysctl.h (it wasn't used | |
662 | and was causing a problem on some systems). Also improved the | |
663 | broken-largefile-locking test to try to avoid failure due to an | |
664 | NFS build-dir. | |
665 | ||
666 | - Fixed a compile problem on systems that don't define | |
667 | AI_NUMERICHOST. | |
668 | ||
669 | - Fixed a compile problem in the popt source for compilers that | |
670 | don't support __attribute__. | |
671 | ||
672 | DEVELOPER RELATED: | |
673 | ||
674 | - Improved the testsuite's "merge" test to work on OSF1. | |
675 | ||
676 | - Two new diffs were added to the patches dir. | |
677 | ||
678 | \f | |
679 | NEWS for rsync 2.6.1 (26 Apr 2004) | |
680 | Protocol: 28 (changed) | |
681 | Changes since 2.6.0: | |
682 | ||
683 | SECURITY FIXES: | |
684 | ||
685 | - Paths sent to an rsync daemon are more thoroughly sanitized when | |
686 | chroot is not used. If you're running a non-read-only rsync | |
687 | daemon with chroot disabled, *please upgrade*, ESPECIALLY if the | |
688 | user privs you run rsync under is anything above "nobody". | |
689 | ||
690 | ENHANCEMENTS: | |
691 | ||
692 | - Lower memory use, more optimal transfer of data over the socket, | |
693 | and lower CPU usage (see the INTERNAL section for details). | |
694 | ||
695 | - The RSYNC_PROXY environment variable can now contain a | |
696 | "USER:PASS@" prefix before the "HOST:PORT" information. | |
697 | (Bardur Arantsson) | |
698 | ||
699 | - The --progress output now mentions how far along in the transfer | |
700 | we are, including both a count of files transferred and a | |
701 | percentage of the total file-count that we've processed. It also | |
702 | shows better current-rate-of-transfer and remaining-transfer-time | |
703 | values. | |
704 | ||
705 | - Documentation changes now attempt to describe some often mis- | |
706 | understood features more clearly. | |
707 | ||
708 | BUG FIXES: | |
709 | ||
710 | - When -x (--one-file-system) is combined with -L (--copy-links) or | |
711 | --copy-unsafe-links, no symlinked files are skipped, even if the | |
712 | referent file is on a different filesystem. | |
713 | ||
714 | - The --link-dest code now works properly for a non-root user when | |
715 | (1) the UIDs of the source and destination differ and -o was | |
716 | specified, or (2) when the group of the source can't be used on | |
717 | the destination and -g was specified. | |
718 | ||
719 | - Fixed a bug in the handling of -H (hard-links) that might cause | |
720 | the expanded PATH/NAME value of the current item to get | |
721 | overwritten (due to an expanded-name caching bug). | |
722 | ||
723 | - We now reset the "new data has been sent" flag at the start of | |
724 | each file we send. This makes sure that an interrupted transfer | |
725 | with the --partial option set doesn't keep a shorter temp file | |
726 | than the current basis file when no new data has been transfered | |
727 | over the wire for that file. | |
728 | ||
729 | - Fixed a byte-order problem in --batch-mode on big-endian machines. | |
730 | (Jay Fenlason) | |
731 | ||
732 | - When using --cvs-exclude, the exclude items we get from a | |
733 | per-directory's .cvsignore file once again only affect that one | |
734 | directory (not all following directories too). The items are also | |
735 | now properly word-split and parsed without any +/- prefix parsing. | |
736 | ||
737 | - When specifying the USER@HOST: prefix for a file, the USER part | |
738 | can now contain an '@', if needed (i.e. the last '@' is used to | |
739 | find the HOST, not the first). | |
740 | ||
741 | - Fixed some bugs in the handling of group IDs for non-root users: | |
742 | (1) It properly handles a group that the sender didn't have a name | |
743 | for (it would previously skip changing the group on any files in | |
744 | that group). (2) If --numeric-ids is used, rsync no longer | |
745 | attempts to set groups that the user doesn't have the permission | |
746 | to set. | |
747 | ||
748 | - Fixed the "refuse options" setting in the rsyncd.conf file. | |
749 | ||
750 | - Improved the -x (--one-file-system) flag's handling of any mount- | |
751 | point directories we encounter. It is both more optimal (in that | |
752 | it no longer does a useless scan of the contents of the mount- | |
753 | point dirs) and also fixes a bug where a remapped mount of the | |
754 | original filesystem could get discovered in a subdir we should be | |
755 | ignoring. | |
756 | ||
757 | - Rsync no longer discards a double-slash at the start of a filename | |
758 | when trying to open the file. It also no longer constructs names | |
759 | that start with a double slash (unless the user supplied them). | |
760 | ||
761 | - Path-specifying options to a daemon should now work the same with | |
762 | or without chroot turned on. Previously, such a option (such as | |
763 | --link-dest) would get its absolute path munged into a relative | |
764 | one if chroot was not on, making that setting fairly useless. | |
765 | Rsync now transforms the path into one that is based on the | |
766 | module's base dir when chroot is not enabled. | |
767 | ||
768 | - Fixed a compatibility problem interacting with older rsync | |
769 | versions that might send us an empty --suffix value without | |
770 | telling us that --backup-dir was specified. | |
771 | ||
772 | - The "hosts allow" option for a daemon-over-remote-shell process | |
773 | now has improved support for IPv6 addresses and a fix for systems | |
774 | that have a length field in their socket structs. | |
775 | ||
776 | - Fixed the ability to request an empty backup --suffix when sending | |
777 | files to an rsync daemon. | |
778 | ||
779 | INTERNAL: | |
780 | ||
781 | - Most of the I/O is now buffered, which results in a pretty large | |
782 | speedup when running under MS Windows. (Craig Barratt) | |
783 | ||
784 | - Optimizations to the name-handling/comparing code have made some | |
785 | significant reductions in user-CPU time for large file sets. | |
786 | ||
787 | - Some cleanup of the variable types make the code more consistent. | |
788 | ||
789 | - Reduced memory requirements of hard link preservation. | |
790 | (J.W. Schultz) | |
791 | ||
792 | - Implemented a new algorithm for hard-link handling that speeds up | |
793 | the code significantly. (J.W. Schultz and Wayne Davison) | |
794 | ||
795 | - The --hard-link option now uses the first existing file in the | |
796 | group of linked files as the basis for the transfer. This | |
797 | prevents the sub-optimal transfer of a file's data when a new | |
798 | hardlink is added on the sending side and it sorts alphabetically | |
799 | earlier in the list than the files that are already present on the | |
800 | receiving side. | |
801 | ||
802 | - Dropped support for protocol versions less than 20 (2.3.0 released | |
803 | 15 Mar 1999) and activated warnings for protocols less than 25 | |
804 | (2.5.0 released 23 Aug 2001). (Wayne Davison and J.W. Schultz, | |
805 | severally) | |
806 | ||
807 | - More optimal data transmission for --hard-links (protocol 28). | |
808 | ||
809 | - More optimal data transmission for --checksum (protocol 28). | |
810 | ||
811 | - Less memory is used when --checksum is specified. | |
812 | ||
813 | - Less memory is used in the file list (a per-file savings). | |
814 | ||
815 | - The generator is now better about not modifying the file list | |
816 | during the transfer in order to avoid a copy-on-write memory | |
817 | bifurcation (on systems where fork() uses shared memory). | |
818 | Previously, rsync's shared memory would slowly become unshared, | |
819 | resulting in real memory usage nearly doubling on the receiving | |
820 | side by the end of the transfer. Now, as long as permissions | |
821 | are being preserved, the shared memory should remain that way | |
822 | for the entire transfer. | |
823 | ||
824 | - Changed hardlink info and file_struct + strings to use allocation | |
825 | pools. This reduces memory use for large file-sets and permits | |
826 | freeing memory to the OS. (J.W. Schultz) | |
827 | ||
828 | - The 2 pipes used between the receiver and generator processes | |
829 | (which are forked on the same machine) were reduced to 1 pipe and | |
830 | the protocol improved so that (1) it is now impossible to have the | |
831 | "redo" pipe fill up and hang rsync, and (2) trailing messages from | |
832 | the receiver don't get lost on their way through the generator | |
833 | over to the sender (which mainly affected hard-link messages and | |
834 | verbose --stats output). | |
835 | ||
836 | - Improved the internal uid/gid code to be more portable and a | |
837 | little more optimized. | |
838 | ||
839 | - The device numbers sent when using --devices are now sent as | |
840 | separate major/minor values with 32-bit accuracy (protocol 28). | |
841 | Previously, the copied devices were sent as a single 32-bit | |
842 | number. This will make inter-operation of 64-bit binaries more | |
843 | compatible with their 32-bit brethren (with both ends of the | |
844 | connection are using protocol 28). Note that optimizations in the | |
845 | binary protocol for sending the device numbers often results in | |
846 | fewer bytes being used than before, even though more precision is | |
847 | now available. | |
848 | ||
849 | - Some cleanup of the exclude/include structures and its code made | |
850 | things clearer (internally), simpler, and more efficient. | |
851 | ||
852 | - The reading & writing of the file-list in batch-mode is now | |
853 | handled by the same code that sends & receives the list over the | |
854 | wire. This makes it much easier to maintain. (Note that the | |
855 | batch code is still considered to be experimental.) | |
856 | ||
857 | BUILD CHANGES: | |
858 | ||
859 | - The configure script now accepts --with-rsyncd-conf=PATH to | |
860 | override the default value of the /etc/rsyncd.conf file. | |
861 | ||
862 | - Fixed configure bug when running "./configure --disable-ipv6". | |
863 | ||
864 | - Fixed compilation problem on Tru64 Unix (having to do with | |
865 | sockaddr.sa_len and sockaddr.sin_len). | |
866 | ||
867 | DEVELOPER RELATED: | |
868 | ||
869 | - Fixed "make test" bug when build dir is not the source dir. | |
870 | ||
871 | - Added a couple extra diffs in the "patches" dir, removed the ones | |
872 | that got applied, and rebuilt the rest. | |

879 | ENHANCEMENTS: | |
880 | ||
881 | * "ssh" is now the default remote shell for rsync. If you want to | |
882 | change this, configure like this: "./configure --with-rsh=rsh". | |
883 | ||
884 | * Added --files-from, --no-relative, --no-implied-dirs, and --from0. | |
885 | Note that --from0 affects the line-ending character for all the | |
886 | files read by the --*-from options. (Wayne Davison) | |
887 | ||
888 | * Length of csum2 is now per-file starting with protocol version | |
889 | 27. (J.W. Schultz) | |
890 | ||
891 | * Per-file dynamic block size is now sqrt(file length). The | |
892 | per-file checksum size is determined according to an algorithm | |
893 | provided by Donovan Baarda which reduces the probability of rsync | |
894 | algorithm corrupting data and falling back using the whole md4 | |
895 | checksums. (J.W. Schultz, Donovan Baarda) | |
896 | ||
897 | * The --stats option no longer includes the (debug) malloc summary | |
898 | unless the verbose option was specified at least twice. | |
899 | ||
900 | * Added a new error/warning code for when files vanish from the | |
901 | sending side. Made vanished source files not interfere with the | |
902 | file-deletion pass when --delete-after was specified. | |
903 | ||
904 | * Various trailing-info sections are now preceded by a newline. | |
905 | ||
906 | BUG FIXES: | |
907 | ||
908 | * Fixed several exclude/include matching bugs when using wild-cards. | |
909 | This has a several user-visible effects, all of which make the | |
910 | matching more consistent and intuitive. This should hopefully not | |
911 | cause anyone problems since it makes the matching work more like | |
912 | what people are expecting. (Wayne Davison) | |
913 | ||
914 | - A pattern with a "**" no longer causes a "*" to match slashes. | |
915 | For example, with "/*/foo/**", "foo" must be 2 levels deep. | |
916 | [If your string has BOTH "*" and "**" wildcards, changing the | |
917 | "*" wildcards to "**" will provide the old behavior in all | |
918 | versions.] | |
919 | ||
920 | - "**/foo" now matches at the base of the transfer (like /foo | |
921 | does). [Use "/**/foo" to get the old behavior in all versions.] | |
922 | ||
923 | - A non-anchored wildcard term floats to match beyond the base of | |
924 | the transfer. E.g. "CVS/R*" matches at the end of the path, | |
925 | just like the non-wildcard term "CVS/Root" does. [Use "/CVS/R*" | |
926 | to get the old behavior in all versions.] | |
927 | ||
928 | - Including a "**" in the match term causes it to be matched | |
929 | against the entire path, not just the name portion, even if | |
930 | there aren't any interior slashes in the term. E.g. "foo**bar" | |
931 | would exclude "/path/foo-bar" (just like before) as well as | |
932 | "/foo-path/baz-bar" (unlike before). [Use "foo*bar" to get the | |
933 | old behavior in all versions.] | |
934 | ||
935 | * The exclude list specified in the daemon's config file is now | |
936 | properly applied to the pulled items no matter how deep the | |
937 | user's file-args are in the source tree. (Wayne Davison) | |
938 | ||
939 | * For protocol version >= 27, mdfour_tail() is called when the | |
940 | block size (including checksum_seed) is a multiple of 64. | |
941 | Previously it was not called, giving the wrong MD4 checksum. | |
942 | (Craig Barratt) | |
943 | ||
944 | * For protocol version >= 27, a 64 bit bit counter is used in | |
945 | mdfour.c as required by the RFC. Previously only a 32 bit bit | |
946 | counter was used, causing incorrect MD4 file checksums for | |
947 | file sizes >= 512MB - 4. (Craig Barratt) | |
948 | ||
949 | * Fixed a crash bug when interacting with older rsync versions and | |
950 | multiple files of the same name are destined for the same dir. | |
951 | (Wayne Davison) | |
952 | ||
953 | * Keep tmp names from overflowing MAXPATHLEN. | |
954 | ||
955 | * Make --link-dest honor the absence of -p, -o, and -g. | |
956 | ||
957 | * Made rsync treat a trailing slash in the destination in a more | |
958 | consistent manner. | |
959 | ||
960 | * Fixed file I/O error detection. (John Van Essen) | |
961 | ||
962 | * Fixed bogus "malformed address {hostname}" message in rsyncd log | |
963 | when checking IP address against hostnames from "hosts allow" | |
964 | and "hosts deny" parameters in config file. | |
965 | ||
966 | * Print heap statistics when verbose >= 2 instead of when >= 1. | |
967 | ||
968 | * Fixed a compression (-z) bug when syncing a mostly-matching file | |
969 | that contains already-compressed data. (Yasuoka Masahiko and | |
970 | Wayne Davison) | |
971 | ||
972 | * Fixed a bug in the --backup code that could cause deleted files | |
973 | to not get backed up. | |
974 | ||
975 | * When the backup code makes new directories, create them with mode | |
976 | 0700 instead of 0755 (since the directory permissions in the | |
977 | backup tree are not yet copied from the main tree). | |
978 | ||
979 | * Call setgroups() in a more portable manner. | |
980 | ||
981 | * Improved file-related error messages to better indicate exactly | |
982 | what pathname failed. (Wayne Davison) | |
983 | ||
984 | * Fixed some bugs in the handling of --delete and --exclude when | |
985 | using the --relative (-R) option. (Wayne Davison) | |
986 | ||
987 | * Fixed bug that prevented regular files from replacing | |
988 | special files and caused a directory in --link-dest or | |
989 | --compare-dest to block the creation of a file with the | |
990 | same path. A directory still cannot be replaced by a | |
991 | regular file unless --delete specified. (J.W. Schultz) | |
992 | ||
993 | * Detect and report when open or opendir succeed but read and | |
994 | readdir fail caused by network filesystem issues and truncated | |
995 | files. (David Norwood, Michael Brown, J.W. Schultz) | |
996 | ||
997 | * Added a fix that should give ssh time to restore the tty settings | |
998 | if the user presses Ctrl-C at an ssh password prompt. | |
999 | ||
1000 | INTERNAL: | |
1001 | ||
1002 | * Eliminated vestigial support for old versions that we stopped | |
1003 | supporting. (J.W. Schultz) | |
1004 | ||
1005 | * Simplified some of the option-parsing code. (Wayne Davison) | |
1006 | ||
1007 | * Some cleanup made to the exclude code, as well as some new | |
1008 | defines added to enhance readability. (Wayne Davison) | |
1009 | ||
1010 | * Changed the protocol-version code so that it can interact at a | |
1011 | lower protocol level than the maximum supported by both sides. | |
1012 | Added an undocumented option, --protocol=N, to force the value | |
1013 | we advertise to the other side (primarily for testing purposes). | |

1033 | * The --delete-after option now implies --delete. (Wayne Davison) | |
1034 | ||
1035 | * The --suffix option can now be used with --backup-dir. (Michael | |
1036 | Zimmerman) | |
1037 | ||
1038 | * Combining "::" syntax with the -rsh/-e option now uses the | |
1039 | specified remote-shell as a transport to talk to a (newly-spawned) | |
1040 | server-daemon. This allows someone to use daemon features, such | |
1041 | as modules, over a secure protocol, such as ssh. (JD Paul) | |
1042 | ||
1043 | * The rsync:// syntax for daemon connections is now accepted in the | |
1044 | destination field. | |
1045 | ||
1046 | * If the file name given to --include-from or --exclude-from is "-", | |
1047 | rsync will read from standard input. (J.W. Schultz) | |
1048 | ||
1049 | * New option --link-dest which is like --compare-dest except that | |
1050 | unchanged files are hard-linked in to the destination directory. | |
1051 | (J.W. Schultz) | |
1052 | ||

1054 | rsync run. (Eugene Chupriyanov and Bo Kersey) | |
1055 | ||
1056 | * Added .svn to --cvs-exclude list to support subversion. (Jon | |
1057 | Middleton) | |
1058 | ||
1059 | * Properly support IPv6 addresses in the rsyncd.conf "hosts allow" | |
1060 | and "hosts deny" fields. (Hideaki Yoshifuji) | |

1067 | ||
1068 | BUG FIXES: | |
1069 | ||
1070 | * Fix "forward name lookup failed" errors on AIX 4.3.3. (John | |
1071 | L. Allen, Martin Pool) | |
1072 | ||
1073 | * Generate each file's rolling-checksum data as we send it, not | |
1074 | in a separate (memory-eating) pass before hand. This prevents | |
1075 | timeout errors on really large files. (Stefan Nehlsen) | |
1076 | ||

1078 | ||

1082 | contains a duplicate name (if it sorts to the end of the file | |
1083 | list) and using --delete. (Wayne Davison) | |
1084 | ||
1085 | * Fixed the file-name duplicate-removal code when dealing with multiple | |
1086 | dups in a row. (Wayne Davison) | |
1087 | ||
1088 | * Fixed a bug that caused rsync to lose the exit status of its child | |
1089 | processes and sometimes return an exit code of 0 instead of showing | |
1090 | an error. (David R. Staples, Dave Dykstra) | |
1091 | ||
1092 | * Fixed bug in --copy-unsafe-links that caused it to be completely | |
1093 | broken. (Dave Dykstra) | |

1128 | otherwise show expected time to complete. (Cameron Simpson) | |
1129 | ||
1130 | * Make "make install-strip" works properly, and "make install" | |
1131 | accepts a DESTDIR variable for help in building binary packages. | |
1132 | (Peter Breitenlohner, Greg Louis) | |
1133 | ||
1134 | * If configured with --enable-maintainer-mode, then on receipt of | |

1321 | * Support for LSB-compliant packaging <http://www.linuxbase.org/> | |
1322 | ||
1323 | * Shell wildcards are allowed in "auth users" lines. | |
1324 | ||
1325 | * Merged UNC rsync+ patch to support creation of standalone patch | |
1326 | sets. By Bert J. Dempsey and Debra Weiss, updated by Jos | |
1327 | Backus. <http://www.ils.unc.edu/i2dsi/unc_rsync+.html> | |
1328 | ||
1329 | * IPv6 support based on a patch from KAME.net, on systems | |
1330 | including modern versions of Linux, Solaris, and HP-UX. Also | |
1331 | includes IPv6 compatibility functions for old OSs by the | |
1332 | Internet Software Consortium, Paul Vixie, the OpenSSH | |
1333 | portability project, and OpenBSD. | |
1334 | ||
1335 | ENHANCEMENTS | |
1336 | ||
1337 | * Include/exclude cluestick: with -vv, print out whether files are | |
1338 | included or excluded and why. | |
1339 | ||
1340 | * Many error messages have more friendly explanations and more | |
1341 | details. | |
1342 | ||
1343 | * Manual page improvements plus scanty protocol documentation. | |
1344 | ||
1345 | * When running as --daemon in the background and using a "log | |
1346 | file" rsyncd.conf directive, close the log file every time it is | |
1347 | open when going to sleep on the socket. This allows the log | |
1348 | file to get cleaned out by another process. | |
1349 | ||
1350 | * Change to using libpopt rather than getopt for processing | |
1351 | options. This makes the code cleaner and the behaviour more | |
1352 | consistent across platforms. popt is included and built if not | |
1353 | installed on the platform. | |
1354 | ||
1355 | * More details in --version, including note about whether 64-bit | |
1356 | files, symlinks and hardlinks are supported. | |
1357 | ||
1358 | * MD4 code may use less CPU cycles. | |
1359 | ||
1360 | * Use mkstemp on systems where it is secure. If we use mktemp, | |
1361 | explain that we do it in a secure way. | |
1362 | ||
1363 | * --whole-file is the default when source and target are on the | |
1364 | local machine. | |
1365 | ||
1366 | BUG FIXES: | |
1367 | ||
1368 | * Fix for various bugs causing rsync to hang. | |
1369 | ||
1370 | * Attempt to fix Large File Summit support on AIX. | |
1371 | ||
1372 | * Attempt to fix error handling lockup bug. | |
1373 | ||
1374 | * Give a non-0 exit code if *any* of the files we have been asked | |
276877cf | 1375 | to transfer fail to transfer. |

1376 | |
1377 | * For log messages containing ridiculously long strings that might | |
1378 | overflow a buffer rsync no longer aborts, but rather prints an | |
1379 | ellipsis at the end of the string. (Patch from Ed Santiago.) | |
1380 | ||
1381 | PLATFORMS: | |
1382 | ||
1383 | * Improved support for UNICOS (tested on Cray T3E and Cray SV1) | |
1384 | ||
1385 | * autoconf2.52 (or later) is now required to rebuild the autoconf | |
276877cf | 1386 | scripts. It is not required to simply build rsync. |
