| 1 | NEWS for rsync 3.0.0 (1 Mar 2008) |
| 2 | Protocol: 30 (changed) |
| 3 | Changes since 2.6.9: |
| 4 | |
| 5 | NOTABLE CHANGES IN BEHAVIOR: |
| 6 | |
| 7 | - The handling of implied directories when using --relative has changed to |
| 8 | send them as directories (e.g. no implied dir is ever sent as a symlink). |
| 9 | This avoids unexpected behavior and should not adversely affect most |
| 10 | people. If you're one of those rare individuals who relied upon having |
| 11 | an implied dir be duplicated as a symlink, you should specify the |
| 12 | transfer of the symlink and the transfer of the referent directory as |
| 13 | separate args. (See also --keep-dirlinks and --no-implied-dirs.) |
| 14 | Also, exclude rules no longer have a partial effect on implied dirs. |
| 15 | |
| 16 | - Requesting a remote file-listing without specifying -r (--recursive) now |
| 17 | sends the -d (--dirs) option to the remote rsync rather than sending -r |
| 18 | along with an extra exclude of /*/*. If the remote rsync does not |
| 19 | understand the -d option (i.e. it is 2.6.3 or older), you will need to |
| 20 | either turn off -d (--no-d), or specify -r --exclude='/*/*' manually. |
| 21 | |
| 22 | - In --dry-run mode, the last line of the verbose summary text is output |
| 23 | with a "(DRY RUN)" suffix to help remind you that no updates were made. |
| 24 | Similarly, --only-write-batch outputs "(BATCH ONLY)". |
| 25 | |
| 26 | - A writable rsync daemon with "use chroot" disabled now defaults to a |
| 27 | symlink-munging behavior designed to make symlinks safer while also |
| 28 | allowing absolute symlinks to be stored and retrieved. This also has |
| 29 | the effect of making symlinks unusable while they're in the daemon's |
| 30 | hierarchy. See the daemon's "munge symlinks" parameter for details. |
| 31 | |
| 32 | - Starting up an extra copy of an rsync daemon will not clobber the pidfile |
| 33 | for the running daemon -- if the pidfile exists, the new daemon will exit |
| 34 | with an error. This means that your wrapper script that starts the rsync |
| 35 | daemon should be made to handle lock-breaking (if you want any automatic |
| 36 | breaking of locks to be done). |
| 37 | |
| 38 | BUG FIXES: |
| 39 | |
| 40 | - A daemon with "use chroot = no" and excluded items listed in the daemon |
| 41 | config file now properly checks an absolute-path arg specified for these |
| 42 | options: --compare-dest, --link-dest, --copy-dest, --partial-dir, |
| 43 | --backup-dir, --temp-dir, and --files-from. |
| 44 | |
| 45 | - A daemon can now be told to disable all user- and group-name translation |
| 46 | on a per-module basis. This avoids a potential problem with a writable |
| 47 | daemon module that has "use chroot" enabled -- if precautions weren't |
| 48 | taken, a user could try to add a missing library and get rsync to use |
| 49 | it. This makes rsync safer by default, and more configurable when id- |
| 50 | translation is not desired. See the daemon's "numeric ids" parameter |
| 51 | for full details. |
| 52 | |
| 53 | - A chroot daemon can now indicate which part of its path should affect the |
| 54 | chroot call, and which part should become an inside-chroot path for the |
| 55 | module. This allows you to have outside-the-transfer paths (such as for |
| 56 | libraries) even when you enable chroot protection. The idiom used in the |
| 57 | rsyncd.conf file is: path = /chroot/dirs/./dirs/inside |
| 58 | |
| 59 | - If a file's data arrived successfully on the receiving side but the |
| 60 | rename of the temporary file to the destination file failed AND the |
| 61 | --remove-source-files (or the deprecated --remove-sent-files) option |
| 62 | was specified, rsync no longer erroneously removes the associated |
| 63 | source file. |
| 64 | |
| 65 | - Fixed the output of -ii when combined with one of the --*-dest options: |
| 66 | it now itemizes all the items, not just the changed ones. |
| 67 | |
| 68 | - Made the output of all file types consistent when using a --*-dest |
| 69 | option. Prior versions would output too many creation events for |
| 70 | matching items. |
| 71 | |
| 72 | - The code that waits for a child pid now handles being interrupted by a |
| 73 | signal. This fixes a problem with the pre-xfer exec function not being |
| 74 | able to get the exit status from the script. |
| 75 | |
| 76 | - A negated filter rule (i.e. with a '!' modifier) no longer loses the |
| 77 | negation when sending the filter rules to the remote rsync. |
| 78 | |
| 79 | - Fixed a problem with the --out-format (aka --log-format) option %f: it |
| 80 | no longer outputs superfluous directory info for a non-daemon rsync. |
| 81 | |
| 82 | - Fixed a problem with -vv (double --verbose) and --stats when "pushing" |
| 83 | files (which includes local copies). Version 2.6.9 would complete the |
| 84 | copy, but exit with an error when the receiver output its memory stats. |
| 85 | |
| 86 | - If --password-file is used on a non-daemon transfer, rsync now complains |
| 87 | and exits. This should help users figure out that they can't use this |
| 88 | option to control a remote shell's password prompt. |
| 89 | |
| 90 | - Make sure that directory permissions of a newly-created destination |
| 91 | directory are handled right when --perms is left off. |
| 92 | |
| 93 | - The itemized output of a newly-created destination directory is now |
| 94 | output as a creation event, not a change event. |
| 95 | |
| 96 | - Improved --hard-link so that more corner cases are handled correctly |
| 97 | when combined with options such as --link-dest and/or --ignore-existing. |
| 98 | |
| 99 | - The --append option no longer updates a file that has the same size. |
| 100 | |
| 101 | - Fixed a bug when combining --backup and --backup-dir with --inplace: |
| 102 | any missing backup directories are now created. |
| 103 | |
| 104 | - Fixed a bug when using --backup and --inplace with --whole-file or |
| 105 | --read-batch: backup files are actually created now. |
| 106 | |
| 107 | - The daemon pidfile is checked and created sooner in the startup sequence. |
| 108 | |
| 109 | - If a daemon module's "path" value is not an absolute pathname, the code |
| 110 | now makes it absolute internally (making it work properly). |
| 111 | |
| 112 | - Ensure that a temporary file always has owner-write permission while we |
| 113 | are writing to it. This avoids problems with some network filesystems |
| 114 | when transfering read-only files. |
| 115 | |
| 116 | - Any errors output about password-file reading no longer cause an error at |
| 117 | the end of the run about a partial transfer. |
| 118 | |
| 119 | - The --read-batch option for protocol 30 now ensures that several more |
| 120 | options are set correctly for the current batch file: --iconv, --acls, |
| 121 | --xattrs, --inplace, --append, and --append-verify. |
| 122 | |
| 123 | - Using --only-write-batch to a daemon receiver now works properly (older |
| 124 | versions would update some files while writing the batch). |
| 125 | |
| 126 | - Avoid outputting a "file has vanished" message when the file is a broken |
| 127 | symlink and --copy-unsafe-links or --copy-dirlinks is used (the code |
| 128 | already handled this for --copy-links). |
| 129 | |
| 130 | - Fixed the combination of --only-write-batch and --dry-run. |
| 131 | |
| 132 | - Fixed rsync's ability to remove files that are not writable by the file's |
| 133 | owner when rsync is running as the same user. |
| 134 | |
| 135 | ENHANCEMENTS: |
| 136 | |
| 137 | - A new incremental-recursion algorithm is now used when rsync is talking |
| 138 | to another 3.x version. This starts the transfer going more quickly |
| 139 | (before all the files have been found), and requires much less memory. |
| 140 | See the --recursive option in the manpage for some restrictions. |
| 141 | |
| 142 | - Lowered memory use in the non-incremental-recursion algorithm for typical |
| 143 | option values (usually saving from 21-29 bytes per file). |
| 144 | |
| 145 | - The default --delete algorithm is now --delete-during when talking to a |
| 146 | 3.x rsync. This is a faster scan than using --delete-before (which is |
| 147 | the default when talking to older rsync versions), and is compatible with |
| 148 | the new incremental recursion mode. |
| 149 | |
| 150 | - Rsync now allows multiple remote-source args to be specified rather than |
| 151 | having to rely on a special space-splitting side-effect of the remote- |
| 152 | shell. Additional remote args must specify the same host or an empty one |
| 153 | (e.g. empty: :file1 or ::module/file2). For example, this means that |
| 154 | local use of brace expansion now works: rsync -av host:dir/{f1,f2} . |
| 155 | |
| 156 | - Added the --protect-args (-s) option, that tells rsync to send most of |
| 157 | the command-line args at the start of the transfer rather than as args |
| 158 | to the remote-shell command. This protects them from space-splitting, |
| 159 | and only interprets basic wildcard special shell characters (*?[). |
| 160 | |
| 161 | - Added the --delete-delay option, which is a more efficient way to delete |
| 162 | files at the end of the transfer without needing a separate delete pass. |
| 163 | |
| 164 | - Added the --acls (-A) option to preserve Access Control Lists. This is |
| 165 | an improved version of the prior patch that was available, and it even |
| 166 | supports OS X ACLs. If you need to have backward compatibility with old, |
| 167 | ACL-patched versions of rsync, apply the acls.diff file from the patches |
| 168 | dir. |
| 169 | |
| 170 | - Added the --xattrs (-X) option to preserve extended attributes. This is |
| 171 | an improved version of the prior patch that was available, and it even |
| 172 | supports OS X xattrs (which includes their resource fork data). If you |
| 173 | need to have backward compatibility with old, xattr-patched versions of |
| 174 | rsync, apply the xattrs.diff file from the patches dir. |
| 175 | |
| 176 | - Added the --fake-super option that allows a non-super user to preserve |
| 177 | all attributes of a file by using a special extended-attribute idiom. |
| 178 | It even supports the storing of foreign ACL data on your backup server. |
| 179 | There is also an analogous "fake super" parameter for an rsync daemon. |
| 180 | |
| 181 | - Added the --iconv option, which allows rsync to convert filenames from |
| 182 | one character-set to another during the transfer. The default is to |
| 183 | make this feature available as long as your system has iconv_open(). |
| 184 | If compilation fails, specify --disable-iconv to configure, and then |
| 185 | rebuild. If you want rsync to perform character-set conversions by |
| 186 | default, you can specify --enable-iconv=CONVERT_STRING with the default |
| 187 | value for the --iconv option that you wish to use. For example, |
| 188 | "--enable-iconv=." is a good choice. See the rsync manpage for an |
| 189 | explanation of the --iconv option's settings. |
| 190 | |
| 191 | - A new daemon config parameter, "charset", lets you control the character- |
| 192 | set that is used during an --iconv transfer to/from a daemon module. You |
| 193 | can also set your daemon to refuse "no-iconv" if you want to force the |
| 194 | client to use an --iconv transfer (requiring an rsync 3.x client). |
| 195 | |
| 196 | - Added the --skip-compress=LIST option to override the default list of |
| 197 | file suffixes that will not be compressed when using --compress (-z). |
| 198 | |
| 199 | - The daemon's default for "dont compress" was extended to include: |
| 200 | *.7z *.mp[34] *.mov *.avi *.ogg *.jpg *.jpeg |
| 201 | The name-matching routine was also optimized to run more quickly. |
| 202 | |
| 203 | - The --max-delete option now outputs a warning if it skipped any file |
| 204 | deletions, including a count of how many deletions were skipped. (Older |
| 205 | versions just silently stopped deleting things.) |
| 206 | |
| 207 | - You may specify --max-delete=0 to a 3.0.0 client to request that it warn |
| 208 | about extraneous files without deleting anything. If you're not sure |
| 209 | what version the client is, you can use the less-obvious --max-delete=-1, |
| 210 | as both old and new versions will treat that as the same request (though |
| 211 | older versions don't warn). |
| 212 | |
| 213 | - The --hard-link option now uses less memory on both the sending and |
| 214 | receiving side for all protocol versions. For protocol 30, the use of a |
| 215 | hashtable on the sending side allows us to more efficiently convey to the |
| 216 | receiver what files are linked together. This reduces the amount of data |
| 217 | sent over the socket by a considerable margin (rather than adding more |
| 218 | data), and limits the in-memory storage of the device+inode information |
| 219 | to just the sending side for the new protocol 30, or to the receiving |
| 220 | side when speaking an older protocol (note that older rsync versions kept |
| 221 | the device+inode information on both sides). |
| 222 | |
| 223 | - The filter rules now support a perishable ("p") modifier that marks rules |
| 224 | that should not have an effect in a directory that is being deleted. e.g. |
| 225 | -f '-p .svn/' would only affect "live" .svn directories. |
| 226 | |
| 227 | - Rsync checks all the alternate-destination args for validity (e.g. |
| 228 | --link-dest). This lets the user know when they specified a directory |
| 229 | that does not exist. |
| 230 | |
| 231 | - If we get an ENOSYS error setting the time on a symlink, we don't |
| 232 | complain about it anymore (for those systems that even support the |
| 233 | setting of the modify-time on a symlink). |
| 234 | |
| 235 | - Protocol 30 now uses MD5 checksums instead of MD4. |
| 236 | |
| 237 | - Changed the --append option to not checksum the existing data in the |
| 238 | destination file, which speeds up file appending. |
| 239 | |
| 240 | - Added the --append-verify option, which works like the older --append |
| 241 | option (verifying the existing data in the destination file). For |
| 242 | compatibility with older rsync versions, any use of --append that is |
| 243 | talking protocol 29 or older will revert to the --append-verify method. |
| 244 | |
| 245 | - Added the --contimeout=SECONDS option that lets the user specify a |
| 246 | connection timeout for rsync daemon access. |
| 247 | |
| 248 | - Documented and extended the support for the RSYNC_CONNECT_PROG variable |
| 249 | that can be used to enhance the client side of a daemon connection. |
| 250 | |
| 251 | - Improved the dashes and double-quotes in the nroff manpage output. |
| 252 | |
| 253 | - Rsync now supports a lot more --no-OPTION override options. |
| 254 | |
| 255 | INTERNAL: |
| 256 | |
| 257 | - The file-list sorting algorithm now uses a sort that keeps any same- |
| 258 | named items in the same order as they were specified. This allows |
| 259 | rsync to always ensure that the first of the duplicates is the one |
| 260 | that will be included in the copy. The new sort is also faster |
| 261 | than the glibc version of qsort() and mergesort(). |
| 262 | |
| 263 | - Rsync now supports the transfer of 64-bit timestamps (time_t values). |
| 264 | |
| 265 | - Made the file-deletion code use a little less stack when recursing |
| 266 | through a directory hierarchy of extraneous files. |
| 267 | |
| 268 | - Fixed a build problem with older (2.x) versions of gcc. |
| 269 | |
| 270 | - Added some isType() functions that make dealing with signed characters |
| 271 | easier without forcing variables via casts. |
| 272 | |
| 273 | - Changed strcat/strcpy/sprintf function calls to use safer versions. |
| 274 | |
| 275 | - Upgraded the included popt version to 1.10.2 and improved its use of |
| 276 | string-handling functions. |
| 277 | |
| 278 | - Added missing prototypes for compatibility functions from the lib dir. |
| 279 | |
| 280 | - Configure determines if iconv() has a const arg, allowing us to avoid a |
| 281 | compiler warning. |
| 282 | |
| 283 | - Made the sending of some numbers more efficient for protocol 30. |
| 284 | |
| 285 | - Make sure that a daemon process doesn't mind if the client was weird and |
| 286 | omitted the --server option. |
| 287 | |
| 288 | - There are more internal logging categories available in protocol 30 than |
| 289 | the age-old FINFO and FERROR, including FERROR_XFER and FWARN. These new |
| 290 | categories allow some errors and warnings to go to stderr without causing |
| 291 | an erroneous end-of-run warning about some files not being able to be |
| 292 | transferred. |
| 293 | |
| 294 | - Improved the use of "const" on pointers. |
| 295 | |
| 296 | - Improved J.W.'s pool_alloc routines to add a way of incrementally freeing |
| 297 | older sections of a pool's memory. |
| 298 | |
| 299 | - The getaddrinfo.c compatibility code in the "lib" dir was replaced with |
| 300 | some new code (derived from samba, derived from PostgreSQL) that has a |
| 301 | better license than the old code. |
| 302 | |
| 303 | DEVELOPER RELATED: |
| 304 | |
| 305 | - Rsync is now licensed under the GPLv3 or later. |
| 306 | |
| 307 | - Rsync is now being maintained in a "git" repository instead of CVS |
| 308 | (though the old CVS repository still exists for historical access). |
| 309 | Several maintenance scripts were updated to work with git. |
| 310 | |
| 311 | - Generated files are no longer committed into the source repository. The |
| 312 | autoconf and autoheader commands are now automatically run during the |
| 313 | normal use of "configure" and "make". The latest dev versions of all |
| 314 | generated files can also be copied from the samba.org web site (see the |
| 315 | prepare-source script's fetch option). |
| 316 | |
| 317 | - The "patches" directory of diff files is now built from branches in the |
| 318 | rsync git repository (branch patch/FOO creates file patches/FOO.diff). |
| 319 | This directory is now distributed in a separate separate tar file named |
| 320 | rsync-patches-VERSION.tar.gz instead of the main rsync-VERSION.tar.gz. |
| 321 | |
| 322 | - The proto.h file is now built using a simple perl script rather than a |
| 323 | complex awk script, which proved to be more widely compatible. |
| 324 | |
| 325 | - When running the tests, we now put our per-test temp dirs into a sub- |
| 326 | directory named testtmp (which is created, if missing). This allows |
| 327 | someone to symlink the testtmp directory to another filesystem (which is |
| 328 | useful if the build dir's filesystem does not support ACLs and xattrs, |
| 329 | but another filesystem does). |
| 330 | |
| 331 | - Rsync now has a way of handling protocol-version changes during the |
| 332 | development of a new protocol version. This causes any out-of-sync |
| 333 | versions to speak an older protocol rather than fail in a cryptic manner. |
| 334 | This addition makes it safer to deploy a pre-release version that may |
| 335 | interact with the public. This new exchange of sub-version info does not |
| 336 | interfere with the {MIN,MAX}_PROTOCOL_VERSION checking algorithm (which |
| 337 | does not have enough range to allow the main protocol number to be |
| 338 | incremented for every minor tweak in that happens during development). |
| 339 | |
| 340 | - The csprotocol.txt file was updated to mention the daemon protocol change |
| 341 | in the 3.0.0 release. |
| 342 | |
| 343 | \f |
| 344 | NEWS for rsync 2.6.9 (6 Nov 2006) |
| 345 | Protocol: 29 (unchanged) |
| 346 | Changes since 2.6.8: |
| 347 | |
| 348 | BUG FIXES: |
| 349 | |
| 350 | - If rsync is interrupted via a handled signal (such as SIGINT), it will |
| 351 | once again clean-up its temp file from the destination dir. |
| 352 | |
| 353 | - Fixed an overzealous sanitizing bug in the handling of the --link-dest, |
| 354 | --copy-dest, and --compare-dest options to a daemon without chroot: if |
| 355 | the copy's destination dir is deeper than the top of the module's path, |
| 356 | these options now accept a safe number of parent-dir (../) references |
| 357 | (since these options are relative to the destination dir). The old code |
| 358 | incorrectly chopped off all "../" prefixes for these options, no matter |
| 359 | how deep the destination directory was in the module's hierarchy. |
| 360 | |
| 361 | - Fixed a bug where a deferred info/error/log message could get sent |
| 362 | directly to the sender instead of being handled by rwrite() in the |
| 363 | generator. This fixes an "unexpected tag 3" fatal error, and should |
| 364 | also fix a potential problem where a deferred info/error message from |
| 365 | the receiver might bypass the log file and get sent only to the client |
| 366 | process. (These problems could only affect an rsync daemon that was |
| 367 | receiving files.) |
| 368 | |
| 369 | - Fixed a bug when --inplace was combined with a --*-dest option and we |
| 370 | update a file's data using an alternate basis file. The code now |
| 371 | notices that it needs to copy the matching data from the basis file |
| 372 | instead of (wrongly) assuming that it was already present in the file. |
| 373 | |
| 374 | - Fixed a bug where using --dry-run with a --*-dest option with a path |
| 375 | relative to a directory that does not yet exist: the affected option |
| 376 | gets its proper path value so that the output of the dry-run is right. |
| 377 | |
| 378 | - Fixed a bug in the %f logfile escape when receiving files: the |
| 379 | destination path is now included in the output (e.g. you can now tell |
| 380 | when a user specifies a subdir inside a module). |
| 381 | |
| 382 | - If the receiving side fails to create a directory, it will now skip |
| 383 | trying to update everything that is inside that directory. |
| 384 | |
| 385 | - If --link-dest is specified with --checksum but without --times, rsync |
| 386 | will now allow a hard-link to be created to a matching link-dest file |
| 387 | even when the file's modify-time doesn't match the server's file. |
| 388 | |
| 389 | - The daemon now calls more timezone-using functions prior to doing a |
| 390 | chroot. This should help some C libraries to generate proper timestamps |
| 391 | from inside a chrooted daemon (and to not try to access /etc/timezone |
| 392 | over and over again). |
| 393 | |
| 394 | - Fixed a bug in the handling of an absolute --partial-dir=ABS_PATH option: |
| 395 | it now deletes an alternate basis file from the partial-dir that was used |
| 396 | to successfully update a destination file. |
| 397 | |
| 398 | - Fixed a bug in the handling of --delete-excluded when using a per-dir |
| 399 | merge file: the merge file is now honored on the receiving side, and |
| 400 | only its unqualified include/exclude commands are ignored (just as is |
| 401 | done for global include/excludes). |
| 402 | |
| 403 | - Fixed a recent bug where --delete was not working when transferring from |
| 404 | the root (/) of the filesystem with --relative enabled. |
| 405 | |
| 406 | - Fixed a recent bug where an --exclude='*' could affect the root (/) of |
| 407 | the filesystem with --relative enabled. |
| 408 | |
| 409 | - When --inplace creates a file, it is now created with owner read/write |
| 410 | permissions (0600) instead of no permissions at all. This avoids a |
| 411 | problem continuing a transfer that was interrupted (since --inplace |
| 412 | will not update a file that has no write permissions). |
| 413 | |
| 414 | - If either --remove-source-files or --remove-sent-files is enabled and we |
| 415 | are unable to remove the source file, rsync now outputs an error. |
| 416 | |
| 417 | - Fixed a bug in the daemon's "incoming chmod" rule: newly-created |
| 418 | directories no longer get the 'F' (file) rules applied to them. |
| 419 | |
| 420 | - Fixed an infinite loop bug when a filter rule was rejected due to being |
| 421 | overly long. |
| 422 | |
| 423 | - When the server receives a --partial-dir option from the client, it no |
| 424 | longer runs the client-side code that adds an assumed filter rule (since |
| 425 | the client will be sending us the rules in the usual manner, and they |
| 426 | may have chosen to override the auto-added rule). |
| 427 | |
| 428 | ENHANCEMENTS: |
| 429 | |
| 430 | - Added the --log-file=FILE and --log-file-format=FORMAT options. These |
| 431 | can be used to tell any rsync to output what it is doing to a log file. |
| 432 | They work with a client rsync, a non-daemon server rsync (see the man |
| 433 | page for instructions), and also allows the overriding of rsyncd.conf |
| 434 | settings when starting a daemon. |
| 435 | |
| 436 | - The --log-format option was renamed to be --out-format to avoid confusing |
| 437 | it with affecting the log-file output. (The old option remains as an |
| 438 | alias for the new to preserve backward compatibility.) |
| 439 | |
| 440 | - Made "log file" and "syslog facility" settable on a per-module basis in |
| 441 | the daemon's config file. |
| 442 | |
| 443 | - Added the --remove-source-files option as a replacement for the (now |
| 444 | deprecated) --remove-sent-files option. This new option removes all |
| 445 | non-dirs from the source directories, even if the file was already |
| 446 | up-to-date. This fixes a problem where interrupting an rsync that |
| 447 | was using --remove-sent-files and restarting it could leave behind |
| 448 | a file that the earlier rsync synchronized, but didn't get to remove. |
| 449 | (The deprecated --remove-sent-files is still understood for now, and |
| 450 | still behaves in the same way as before.) |
| 451 | |
| 452 | - Added the option --no-motd to suppress the message-of-the-day output |
| 453 | from a daemon when doing a copy. (See the manpage for a caveat.) |
| 454 | |
| 455 | - Added a new environment variable to the pre-/post-xfer exec commands (in |
| 456 | the daemon's config file): RSYNC_PID. This value will be the same in |
| 457 | both the pre- and post-xfer commands, so it can be used as a unique ID |
| 458 | if the pre-xfer command wants to cache some arg/request info for the |
| 459 | post-xfer command. |
| 460 | |
| 461 | INTERNAL: |
| 462 | |
| 463 | - Did a code audit using IBM's code-checker program and made several |
| 464 | changes, including: replacing most of the strcpy() and sprintf() |
| 465 | calls with strlcpy(), snprintf(), and memcpy(), adding a 0-value to |
| 466 | an enum that had been intermingling a literal 0 with the defined enum |
| 467 | values, silencing some uninitialized memory checks, marking some |
| 468 | functions with a "noreturn" attribute, and changing an "if" that |
| 469 | could never succeed on some platforms into a pre-processor directive |
| 470 | that conditionally compiles the code. |
| 471 | |
| 472 | - Fixed a potential bug in f_name_cmp() when both the args are a |
| 473 | top-level "." dir (which doesn't happen in normal operations). |
| 474 | |
| 475 | - Changed exit_cleanup() so that it can never return instead of exit. |
| 476 | The old code might return if it found the exit_cleanup() function |
| 477 | was being called recursively. The new code is segmented so that |
| 478 | any recursive calls move on to the next step of the exit-processing. |
| 479 | |
| 480 | - The macro WIFEXITED(stat) will now be defined if the OS didn't already |
| 481 | define it. |
| 482 | |
| 483 | DEVELOPER RELATED: |
| 484 | |
| 485 | - The acls.diff and xattrs.diff patches have received a bunch of work to |
| 486 | make them much closer to being acceptable in the main distribution. |
| 487 | The xattrs patch also has some preliminary Mac OS X and FreeBSD |
| 488 | compatibility code that various system types to exchange extended |
| 489 | file-attributes. |
| 490 | |
| 491 | - A new diff in the patches dir, fake-root.diff, allows rsync to |
| 492 | maintain a backup hierarchy with full owner, group, and device info |
| 493 | without actually running as root. It does this using a special |
| 494 | extended attribute, so it depends on xattrs.diff (which depends on |
| 495 | acls.diff). |
| 496 | |
| 497 | - The rsync.yo and rsyncd.conf.yo files have been updated to work |
| 498 | better with the latest yodl 2.x releases. |
| 499 | |
| 500 | - Updated config.guess and config.sub to their 2006-07-02 versions. |
| 501 | |
| 502 | - Updated various files to include the latest FSF address and to have |
| 503 | consistent opening comments. |

| 506 | NEWS for rsync 2.6.8 (22 Apr 2006) |
| 507 | Protocol: 29 (unchanged) |
| 508 | Changes since 2.6.7: |
| 509 | |
| 510 | BUG FIXES: |
| 511 | |
| 512 | - Fixed a bug in the exclude code where an anchored exclude without any |
| 513 | wildcards fails to match an absolute source arg, but only when --relative |
| 514 | is in effect. |
| 515 | |
| 516 | - Improved the I/O code for the generator to fix a potential hang when the |
| 517 | receiver gets an EOF on the socket but the generator's select() call |
| 518 | never indicates that the socket is writable for it to be notified about |
| 519 | the EOF. (This can happen when using stunnel). |
| 520 | |
| 521 | - Fixed a problem with the file-reading code where a failed read (such as |
| 522 | that caused by a bad sector) would not advance the file's read-position |
| 523 | beyond the failed read's data. |
| 524 | |
| 525 | - Fixed a logging bug where the "log file" directive was not being honored |
| 526 | in a single-use daemon (one spawned by a remote-shell connection or by |
| 527 | init). |
| 528 | |
| 529 | - If rsync cannot honor the --delete option, we output an error and exit |
| 530 | instead of silently ignoring the option. |
| 531 | |
| 532 | - Fixed a bug in the --link-dest code that prevented special files (such as |
| 533 | fifos) from being linked. |
| 534 | |
| 535 | - The ability to hard-link symlinks and special files is now determined at |
| 536 | configure time instead of at runtime. This fixes a bug with --link-dest |
| 537 | creating a hard-link to a symlink's referent on a BSD system. |
| 538 | |
| 539 | ENHANCEMENTS: |
| 540 | |
| 541 | - In daemon mode, if rsync fails to bind to the requested port, the |
| 542 | error(s) returned by socket() and/or bind() are now logged. |
| 543 | |
| 544 | - When we output a fatal error, we now output the version of rsync in the |
| 545 | message. |
| 546 | |
| 547 | - Improved the documentation for the --owner and --group options. |
| 548 | |
| 549 | - The rsyncstats script in "support" has an improved line-parsing regex |
| 550 | that is easier to read and also makes it to parse syslog-generated lines. |
| 551 | |
| 552 | - A new script in "support": file-attr-restore, can be used to restore the |
| 553 | attributes of a file-set (the permissions, ownership, and group info) |
| 554 | taken from the cached output of a "find ARG... -ls" command. |
| 555 | |
| 556 | DEVELOPER RELATED: |
| 557 | |
| 558 | - Removed the unused function write_int_named(), the unused variable |
| 559 | io_read_phase, and the rarely used variable io_write_phase. This also |
| 560 | elides the confusing 'phase "unknown"' part of one error message. |
| 561 | |
| 562 | - Removed two unused configure checks and two related (also unused) |
| 563 | compatibility functions. |
| 564 | |
| 565 | - The xattrs.diff patch received a security fix that prevents a potential |
| 566 | buffer overflow in the receive_xattr() code. |
| 567 | |
| 568 | - The acls.diff patch has been improved quite a bit, with more to come. |
| 569 | |
| 570 | - A new patch was added: log-file.diff. This contains an early version of |
| 571 | a future option, --log-file=FILE, that will allow any rsync to log its |
| 572 | actions to a file (something that only a daemon supports at present). |
| 573 | |
| 574 | \f |
| 575 | NEWS for rsync 2.6.7 (11 Mar 2006) |
| 576 | Protocol: 29 (unchanged) |
| 577 | Changes since 2.6.6: |
| 578 | |
| 579 | OUTPUT CHANGES: |
| 580 | |
| 581 | - The letter 'D' in the itemized output was being used for both devices |
| 582 | (character or block) as well as other special files (such as fifos and |
| 583 | named sockets). This has changed to separate non-device special files |
| 584 | under the 'S' designation (e.g. "cS+++++++ path/fifo"). See also the |
| 585 | "--specials" option, below. |
| 586 | |
| 587 | - The way rsync escapes unreadable characters has changed. First, rsync |
| 588 | now has support for recognizing valid multibyte character sequences in |
| 589 | your current locale, allowing it to escape fewer characters than before |
| 590 | for a locale such as UTF-8. Second, it now uses an escape idiom of |
| 591 | "\#123", which is the literal string "\#" followed by exactly 3 octal |
| 592 | digits. Rsync no longer doubles a backslash character in a filename |
| 593 | (e.g. it used to output "foo\\bar" when copying "foo\bar") -- now it only |
| 594 | escapes a backslash that is followed by a hash-sign and 3 digits (0-9) |
| 595 | (e.g. it will output "foo\#134#789" when copying "foo\#789"). See also |
| 596 | the --8-bit-output (-8) option, mentioned below. |
| 597 | |
| 598 | Script writers: the local rsync is the one that outputs escaped names, |
| 599 | so if you need to support unescaping of filenames for older rsyncs, I'd |
| 600 | suggest that you parse the output of "rsync --version" and only use the |
| 601 | old unescaping rules for 2.6.5 and 2.6.6. |
| 602 | |
| 603 | BUG FIXES: |
| 604 | |
| 605 | - Fixed a really old bug that caused --checksum (-c) to checksum all the |
| 606 | files encountered during the delete scan (ouch). |
| 607 | |
| 608 | - Fixed a potential hang in a remote generator: when the receiver gets a |
| 609 | read-error on the socket, it now signals the generator about this so that |
| 610 | the generator does not try to send any of the terminating error messages |
| 611 | to the client (avoiding a potential hang in some setups). |
| 612 | |
| 613 | - Made hard-links work with symlinks and devices again. |
| 614 | |
| 615 | - If the sender gets an early EOF reading a source file, we propagate this |
| 616 | error to the receiver so that it can discard the file and try requesting |
| 617 | it again (which is the existing behavior for other kinds of read errors). |
| 618 | |
| 619 | - If a device-file/special-file changes permissions, rsync now updates the |
| 620 | permissions without recreating the file. |
| 621 | |
| 622 | - If the user specifies a remote-host for both the source and destination, |
| 623 | we now output a syntax error rather than trying to open the destination |
| 624 | hostspec as a filename. |
| 625 | |
| 626 | - When --inplace creates a new destination file, rsync now creates it with |
| 627 | permissions 0600 instead of 0000 -- this makes restarting possible when |
| 628 | the transfer gets interrupted in the middle of sending a new file. |
| 629 | |
| 630 | - Reject the combination of --inplace and --sparse since the sparse-output |
| 631 | algorithm doesn't work when overwriting existing data. |
| 632 | |
| 633 | - Fixed the directory name in the error that is output when pop_dir() |
| 634 | fails. |
| 635 | |
| 636 | - Really fixed the parsing of a "!" entry in .cvsignore files this time. |
| 637 | |
| 638 | - If the generator gets a stat() error on a file, output it (this used to |
| 639 | require at least -vv for the error to be seen). |
| 640 | |
| 641 | - If waitpid() fails or the child rsync didn't exit cleanly, we now handle |
| 642 | the exit status properly and generate a better error. |
| 643 | |
| 644 | - Fixed some glitches in the double-verbose output when using --copy-dest, |
| 645 | --link-dest, or --compare-dest. Also improved how the verbose output |
| 646 | handles hard-links (within the transfer) that had an up-to-date alternate |
| 647 | "dest" file, and copied files (via --copy-dest). |
| 648 | |
| 649 | - Fixed the matching of the dont-compress items (e.g. *.gz) against files |
| 650 | that have a path component containing a slash. |
| 651 | |
| 652 | - If the code reading a filter/exclude file gets an EINTR error, rsync now |
| 653 | clears the error flag on the file handle so it can keep on reading. |
| 654 | |
| 655 | - If --relative is active, the sending side cleans up trailing "/" or "/." |
| 656 | suffixes to avoid triggering a bug in older rsync versions. Also, we now |
| 657 | reject a ".." dir if it would be sent as a relative dir. |
| 658 | |
| 659 | - If a non-directory is in the way of a directory and rsync is run with |
| 660 | --dry-run and --delete, rsync no longer complains about not being able |
| 661 | to opendir() the not-yet present directory. |
| 662 | |
| 663 | - When --list-only is used and a non-existent local destination dir was |
| 664 | also specified as a destination, rsync no longer generates a warning |
| 665 | about being unable to create the missing directory. |
| 666 | |
| 667 | - Fixed some problems with --relative --no-implied-dirs when the |
| 668 | destination directory did not yet exist: we can now create a symlink or |
| 669 | device when it is the first thing in the missing dir, and --fuzzy no |
| 670 | longer complains about being unable to open the missing dir. |
| 671 | |
| 672 | - Fixed a bug where the --copy-links option would not affect implied |
| 673 | directories without --copy-unsafe-links (see --relative). |
| 674 | |
| 675 | - Got rid of the need for --force to be used in some circumstances with |
| 676 | --delete-after (making it consistent with --delete-before/-during). |
| 677 | |
| 678 | - Rsync now ignores the SIGXFSZ signal, just in case your OS sends this |
| 679 | when a file is too large (rsync handles the write error). |
| 680 | |
| 681 | - Fixed a bug in the Proxy-Authorization header's base64-encoded value: it |
| 682 | was not properly padded with trailing '=' chars. This only affects a |
| 683 | user that need to use a password-authenticated proxy for an outgoing |
| 684 | daemon-rsync connection. |
| 685 | |
| 686 | - If we're transferring an empty directory to a new name, rsync no longer |
| 687 | forces S_IWUSR if it wasn't already set, nor does it accidentally leave |
| 688 | it set. |
| 689 | |
| 690 | - Fixed a bug in the debug output (-vvvvv) that could mention the wrong |
| 691 | checksum for the current file offset. |
| 692 | |
| 693 | - Rsync no longer allows a single directory to be copied over a non- |
| 694 | directory destination arg. |
| 695 | |
| 696 | ENHANCEMENTS: |
| 697 | |
| 698 | - Added the --append option that makes rsync append data onto files that |
| 699 | are longer on the source than the destination (this includes new files). |
| 700 | |
| 701 | - Added the --min-size=SIZE option to exclude small files from the |
| 702 | transfer. |
| 703 | |
| 704 | - Added the --compress-level option to allow you to set how aggressive |
| 705 | rsync's compression should be (this option implies --compress). |
| 706 | |
| 707 | - Enhanced the parsing of the SIZE value for --min-size and --max-size to |
| 708 | allow easy entry of multiples of 1000 (instead of just multiples of 1024) |
| 709 | and off-by-one values too (e.g. --max-size=8mb-1). |
| 710 | |
| 711 | - Added the --8-bit-output (-8) option, which tells rsync to avoid escaping |
| 712 | high-bit characters that it thinks are unreadable in the current locale. |
| 713 | |
| 714 | - The new option --human-readable (-h) changes the output of --progress, |
| 715 | --stats, and the end-of-run summary to be easier to read. If repeated, |
| 716 | the units become powers of 1024 instead of powers of 1000. (The old |
| 717 | meaning of -h, as a shorthand for --help, still works as long as you |
| 718 | just use it on its own, as in "rsync -h".) |
| 719 | |
| 720 | - If lutimes() and/or lchmod() are around, use them to allow the |
| 721 | preservation of attributes on symlinks. |
| 722 | |
| 723 | - The --link-dest option now affects symlinks and devices (when possible). |
| 724 | |
| 725 | - Added two config items to the rsyncd.conf parsing: "pre-xfer exec" and |
| 726 | "post-xfer exec". These allow a command to be specified on a per-module |
| 727 | basis that will be run before and/or after a daemon-mode transfer. (See |
| 728 | the man page for a list of the environment variables that are set with |
| 729 | information about the transfer.) |
| 730 | |
| 731 | - When using the --relative option, you can now insert a dot dir in |
| 732 | the source path to indicate where the replication of the source dirs |
| 733 | should start. For example, if you specify a source path of |
| 734 | rsync://host/module/foo/bar/./baz/dir with -R, rsync will now only |
| 735 | replicate the "baz/dir" part of the source path (note: a trailing |
| 736 | dot dir is unaffected unless it also has a trailing slash). |
| 737 | |
| 738 | - Added some new --no-FOO options that make it easier to override unwanted |
| 739 | implied or default options. For example, "-a --no-o" (aka "--archive |
| 740 | --no-owner") can be used to turn off the preservation of file ownership |
| 741 | that is implied by -a. |
| 742 | |
| 743 | - Added the --chmod=MODE option that allows the destination permissions to |
| 744 | be changed from the source permissions. E.g. --chmod=g+w,o-rwx |
| 745 | |
| 746 | - Added the "incoming chmod" and "outgoing chmod" daemon options that allow |
| 747 | a module to specify what permissions changes should be applied to all |
| 748 | files copied to and from the daemon. |
| 749 | |
| 750 | - Allow the --temp-dir option to be specified when starting a daemon, which |
| 751 | sets the default temporary directory for incoming files. |
| 752 | |
| 753 | - If --delete is combined with --dirs without --recursive, rsync will now |
| 754 | delete in any directory whose content is being synchronized. |
| 755 | |
| 756 | - If --backup is combined with --delete without --backup-dir (and without |
| 757 | --delete-excluded), we add a "protect" filter-rule to ensure that files |
| 758 | with the backup suffix are not deleted. |
| 759 | |
| 760 | - The file-count stats that are output by --progress were improved to |
| 761 | better indicate what the numbers mean. For instance, the output: |
| 762 | "(xfer#5, to-check=8383/9999)" indicates that this was the fifth file |
| 763 | to be transferred, and we still need to check 8383 more files out of |
| 764 | a total of 9999. |
| 765 | |
| 766 | - The include/exclude code now allows a dir/*** directive (with 3 trailing |
| 767 | stars) to match both the dir itself as well as all the content below the |
| 768 | dir (dir/** would not match the dir). |
| 769 | |
| 770 | - Added the --prune-empty-dirs (-m) option that makes the receiving rsync |
| 771 | discard empty chains of directories from the file-list. This makes it |
| 772 | easier to selectively copy files from a source hierarchy and end up with |
| 773 | just the directories needed to hold the resulting files. |
| 774 | |
| 775 | - If the --itemize-changes (-i) option is repeated, rsync now includes |
| 776 | unchanged files in the itemized output (similar to -vv, but without all |
| 777 | the other verbose messages that can get in the way). Of course, the |
| 778 | client must be version 2.6.7 for this to work, but the remote rsync only |
| 779 | needs to be 2.6.7 if you're pushing files. |
| 780 | |
| 781 | - Added the --specials option to tell rsync to copy non-device special |
| 782 | files (which rsync now attempts even as a normal user). The --devices |
| 783 | option now requests the copying of just devices (character and block). |
| 784 | The -D option still requests both (e.g. --devices and --specials), -a |
| 785 | still implies -D, and non-root users still get a silent downgrade that |
| 786 | omits device copying. |
| 787 | |
| 788 | - Added the --super option to make the receiver always attempt super-user |
| 789 | activities. This is useful for systems that allow things such as devices |
| 790 | to be created or ownership to be set without being UID 0, and is also |
| 791 | useful for someone who wants to ensure that errors will be output if the |
| 792 | receiving rsync isn't being run as root. |
| 793 | |
| 794 | - Added the --sockopts option for those few who want to customize the TCP |
| 795 | options used to contact a daemon rsync. |
| 796 | |
| 797 | - Added a way for the --temp-dir option to be combined with a partial-dir |
| 798 | setting that lets rsync avoid non-atomic updates (for those times when |
| 799 | --temp-dir is not being used because space is tight). |
| 800 | |
| 801 | - A new support script, files-to-excludes, will transform a list of files |
| 802 | into a set of include/exclude directives that will copy those files. |
| 803 | |
| 804 | - A new option, --executability (-E) can be used to preserve just the |
| 805 | execute bit on files, for those times when using the --perms option is |
| 806 | not desired. |
| 807 | |
| 808 | - The daemon now logs each connection and also each module-list request |
| 809 | that it receives. |
| 810 | |
| 811 | - New log-format options: %M (modtime), %U (uid), %G (gid), and %B |
| 812 | (permission bits, e.g. "rwxr-xrwt"). |
| 813 | |
| 814 | - The --dry-run option no longer forces the enabling of --verbose. |
| 815 | |
| 816 | - The --remove-sent-files option now does a better job of incrementally |
| 817 | removing the sent files on the sending side (older versions tended to |
| 818 | clump up all the removals at the end). |
| 819 | |
| 820 | - A daemon now supersedes its minimal SIGCHLD handler with the standard |
| 821 | PID-remembering version after forking. This ensures that the generator |
| 822 | can get the child-exit status from the receiver. |
| 823 | |
| 824 | - Use of the --bwlimit option no longer interferes with the remote rsync |
| 825 | sending error messages about invalid/refused options. |
| 826 | |
| 827 | - Rsync no longer returns a usage error when used with one local source arg |
| 828 | and no destination: this now implies the --list-only option, just like |
| 829 | the comparable situation with a remote source arg. |
| 830 | |
| 831 | - Added the --copy-dirlinks option, a more limited version of --copy-links. |
| 832 | |
| 833 | - Various documentation improvements, including: a better synopsis, some |
| 834 | improved examples, a better discussion of the presence and absence of |
| 835 | --perms (including how it interacts with the new --executability and |
| 836 | --chmod options), an extended discussion of --temp-dir, an improved |
| 837 | discussion of --partial-dir, a better description of rsync's pattern |
| 838 | matching characters, an improved --no-implied-dirs section, and the |
| 839 | documenting of what the --stats option outputs. |
| 840 | |
| 841 | - Various new and updated diffs in the patches dir, including: acls.diff, |
| 842 | xattrs.diff, atimes.diff, detect-renamed.diff, and slp.diff. |
| 843 | |
| 844 | INTERNAL: |
| 845 | |
| 846 | - We now use sigaction() and sigprocmask() if possible, and fall back on |
| 847 | signal() if not. Using sigprocmask() ensures that rsync enables all the |
| 848 | signals that it needs, just in case it was started in a masked state. |
| 849 | |
| 850 | - Some buffer sizes were expanded a bit, particularly on systems where |
| 851 | MAXPATHLEN is overly small (e.g. cygwin). |
| 852 | |
| 853 | - If io_printf() tries to format more data than fits in the buffer, exit |
| 854 | with an error instead of transmitting a truncated buffer. |
| 855 | |
| 856 | - If a va_copy macro is defined, lib/snprintf.c will use it when defining |
| 857 | the VA_COPY macro. |
| 858 | |
| 859 | - Reduced the amount of stack memory needed for each level of directory |
| 860 | recursion by nearly MAXPATHLEN bytes. |
| 861 | |
| 862 | - The wildmatch function was extended to allow an array of strings to be |
| 863 | supplied as the string to match. This allows the exclude code to do less |
| 864 | string copying. |
| 865 | |
| 866 | - Got rid of the safe_fname() function (and all the myriad calls) and |
| 867 | replaced it with a new function in the log.c code that filters all the |
| 868 | output going to the terminal. |
| 869 | |
| 870 | - Unified the f_name() and the f_name_to() functions. |
| 871 | |
| 872 | - Improved the hash-table code the sender uses to handle checksums to make |
| 873 | it use slightly less memory and run just a little faster. |
| 874 | |
| 875 | DEVELOPER RELATED: |
| 876 | |
| 877 | - The diffs in the patches dir now require "patch -p1 <DIFF" instead of |
| 878 | the previous -p0. Also, the version included in the release tar now |
| 879 | affect generated files (e.g. configure, rsync.1, proto.h, etc.), so |
| 880 | it is no longer necessary to run autoconf and/or yodl unless you're |
| 881 | applying a patch that was checked out from CVS. |
| 882 | |
| 883 | - Several diffs in the patches dir now use the proper --enable-FOO |
| 884 | configure option instead of --with-FOO to turn on the inclusion of |
| 885 | the newly patched feature. |
| 886 | |
| 887 | - There is a new script, "prepare-source" than can be used to update the |
| 888 | various generated files (proto.h, configure, etc.) even before configure |
| 889 | has created the Makefile (this is mainly useful when patching the source |
| 890 | with a patch that doesn't affect generated files). |
| 891 | |
| 892 | - The testsuite now sets HOME so that it won't be affected by a file such |
| 893 | as ~/.popt. |

| 896 | NEWS for rsync 2.6.6 (28 Jul 2005) |
| 897 | Protocol: 29 (unchanged) |
| 898 | Changes since 2.6.5: |
| 899 | |
| 900 | SECURITY FIXES: |
| 901 | |
| 902 | - The zlib code was upgraded to version 1.2.3 in order to make it more |
| 903 | secure. While the widely-publicized security problem in zlib 1.2.2 did |
| 904 | not affect rsync, another security problem surfaced that affects rsync's |
| 905 | zlib 1.1.4. |
| 906 | |
| 907 | BUG FIXES: |
| 908 | |
| 909 | - The setting of flist->high in clean_flist() was wrong for an empty list. |
| 910 | This could cause flist_find() to crash in certain rare circumstances |
| 911 | (e.g. if just the right directory setup was around when --fuzzy was |
| 912 | combined with --link-dest). |
| 913 | |
| 914 | - The outputting of hard-linked files when verbosity was > 1 was not right: |
| 915 | (1) Without -i it would output the name of each hard-linked file as |
| 916 | though it had been changed; it now outputs a "is hard linked" message for |
| 917 | the file. (2) With -i it would output all dots for the unchanged |
| 918 | attributes of a hard-link; it now changes those dots to spaces, as is |
| 919 | done for other totally unchanged items. |
| 920 | |
| 921 | - When backing up a changed symlink or device, get rid of any old backup |
| 922 | item so that we don't get an "already exists" error. |
| 923 | |
| 924 | - A couple places that were comparing a local and a remote modification- |
| 925 | time were not honoring the --modify-window option. |
| 926 | |
| 927 | - Fixed a bug where the 'p' (permissions) itemized-changes flag might get |
| 928 | set too often (if some non-significant mode bits differed). |
| 929 | |
| 930 | - Fixed a really old, minor bug that could cause rsync to warn about being |
| 931 | unable to mkdir() a path that ends in "/." because it just created the |
| 932 | directory (required --relative, --no-implied-dirs, a source path that |
| 933 | ended in either a trailing slash or a trailing "/.", and a non-existing |
| 934 | destination dir to tickle the bug in a recent version). |
| 935 | |
| 936 | ENHANCEMENTS: |
| 937 | |
| 938 | - Made the "max verbosity" setting in the rsyncd.conf file settable on a |
| 939 | per-module basis (which now matches the documentation). |
| 940 | |
| 941 | - The support/rrsync script has been upgraded to verify the args of options |
| 942 | that take args (instead of rejecting any such options). The script was |
| 943 | also changed to try to be more secure and to fix a problem in the parsing |
| 944 | of a pull operation that has multiple sources. |
| 945 | |
| 946 | - Improved the documentation that explains the difference between a |
| 947 | normal daemon transfer and a daemon-over remote-shell transfer. |
| 948 | |
| 949 | - Some of the diffs supplied in the patches dir were fixed and/or |
| 950 | improved. |
| 951 | |
| 952 | BUILD CHANGES: |
| 953 | |
| 954 | - Made configure define NOBODY_USER (currently hard-wired to "nobody") and |
| 955 | NOBODY_GROUP (set to either "nobody" or "nogroup" depending on what we |
| 956 | find in the /etc/group file). |
| 957 | |
| 958 | - Added a test to the test suite, itemized.test, that tests the output of |
| 959 | -i (log-format w/%i) and some double-verbose messages. |
| 960 | |
| 961 | \f |
| 962 | NEWS for rsync 2.6.5 (1 Jun 2005) |
| 963 | Protocol: 29 (unchanged) |
| 964 | Changes since 2.6.4: |
| 965 | |
| 966 | OUTPUT CHANGES: |
| 967 | |
| 968 | - Non-printable chars in filenames are now output using backslash- |
| 969 | escaped characters rather than '?'s. Any non-printable character is |
| 970 | output using 3 digits of octal (e.g. "\n" -> "\012"), and a backslash |
| 971 | is now output as "\\". Rsync also uses your locale setting, which |
| 972 | can make it treat fewer high-bit characters as non-printable. |
| 973 | |
| 974 | - If rsync received an empty file-list when pulling files, it would |
| 975 | output a "nothing to do" message and exit with a 0 (success) exit |
| 976 | status, even if the remote rsync returned an error (it did not do |
| 977 | this under the same conditions when pushing files). This was changed |
| 978 | to make the pulling behavior the same as the pushing behavior: we |
| 979 | now do the normal end-of-run outputting (depending on options) and |
| 980 | exit with the appropriate exit status. |
| 981 | |
| 982 | BUG FIXES: |
| 983 | |
| 984 | - A crash bug was fixed when a daemon had its "path" set to "/", did |
| 985 | not have chroot enabled, and used some anchored excludes in the |
| 986 | rsyncd.conf file. |
| 987 | |
| 988 | - Fixed a bug in the transfer of a single file when -H is specified |
| 989 | (rsync would either infinite loop or perhaps crash). |
| 990 | |
| 991 | - Fixed a case where the generator might try (and fail) to tweak the |
| 992 | write-permissions of a read-only directory in list-only mode (this |
| 993 | only caused an annoying warning message). |
| 994 | |
| 995 | - If --compare-dest or --link-dest uses a locally-copied file as the |
| 996 | basis for an updated version, log this better when --verbose or -i |
| 997 | is in effect. |
| 998 | |
| 999 | - Fixed the accidental disabling of --backup during the --delete-after |
| 1000 | processing. |
| 1001 | |
| 1002 | - Restored the ability to use the --address option in client mode (in |
| 1003 | addition to its use in daemon mode). |
| 1004 | |
| 1005 | - Make sure that some temporary progress information from the delete |
| 1006 | processing does not get left on the screen when it is followed by a |
| 1007 | newline. |
| 1008 | |
| 1009 | - When --existing skips a directory with extra verbosity, refer to it |
| 1010 | as a "directory", not a "file". |
| 1011 | |
| 1012 | - When transferring a single file to a different-named file, any |
| 1013 | generator messages that are source-file related no longer refer to |
| 1014 | the file by the destination filename. |
| 1015 | |
| 1016 | - Fixed a bug where hard-linking a group of files might fail if the |
| 1017 | generator hasn't created a needed destination directory yet. |
| 1018 | |
| 1019 | - Fixed a bug where a hard-linked group of files that is newly-linked |
| 1020 | to a file in a --link-dest dir doesn't link the files from the rest |
| 1021 | of the cluster. |
| 1022 | |
| 1023 | - When deleting files with the --one-file-system (-x) option set, rsync |
| 1024 | no longer tries to remove files from inside a mount-point on the |
| 1025 | receiving side. Also, we don't complain about being unable to remove |
| 1026 | the mount-point dir. |
| 1027 | |
| 1028 | - Fixed a compatibility problem when using --cvs-ignore (-C) and |
| 1029 | sending files to an older rsync without using --delete. |
| 1030 | |
| 1031 | - Make sure that a "- !" or "+ !" include/exclude pattern does not |
| 1032 | trigger the list-clearing action that is reserved for "!". |
| 1033 | |
| 1034 | - Avoid a timeout in the generator when the sender/receiver aren't |
| 1035 | handling the generator's checksum output quickly enough. |
| 1036 | |
| 1037 | - Fixed the omission of some directories in the delete processing when |
| 1038 | --relative (-R) was combined with a source path that had a trailing |
| 1039 | slash. |
| 1040 | |
| 1041 | - Fixed a case where rsync would erroneously delete some files and then |
| 1042 | re-transfer them when the options --relative (-R) and --recursive |
| 1043 | (-r) were both enabled (along with --delete) and a source path had a |
| 1044 | trailing slash. |
| 1045 | |
| 1046 | - Make sure that --max-size doesn't affect a device or a symlink. |
| 1047 | |
| 1048 | - Make sure that a system with a really small MAXPATHLEN does not cause |
| 1049 | the buffers in readfd_unbuffered() to be too small to receive normal |
| 1050 | messages. (This mainly affected Cygwin.) |
| 1051 | |
| 1052 | - If a source pathname ends with a filename of "..", treat it as if |
| 1053 | "../" had been specified (so that we don't copy files to the parent |
| 1054 | dir of the destination). |
| 1055 | |
| 1056 | - If --delete is combined with a file-listing rsync command (i.e. no |
| 1057 | transfer is happening), avoid outputting a warning that we couldn't |
| 1058 | delete anything. |
| 1059 | |
| 1060 | - If --stats is specified with --delete-after, ensure that all the |
| 1061 | "deleting" messages are output before the statistics. |
| 1062 | |
| 1063 | - Improved one "if" in the deletion code that was only checking errno |
| 1064 | for ENOTEMPTY when it should have also been checking for EEXIST (for |
| 1065 | compatibility with OS variations). |
| 1066 | |
| 1067 | ENHANCEMENTS: |
| 1068 | |
| 1069 | - Added the --only-write-batch=FILE option that may be used (instead |
| 1070 | of --write-batch=FILE) to create a batch file without doing any |
| 1071 | actual updating of the destination. This allows you to divert all |
| 1072 | the file-updating data away from a slow data link (as long as you |
| 1073 | are pushing the data to the remote server when creating the batch). |
| 1074 | |
| 1075 | - When the generator is taking a long time to fill up its output buffer |
| 1076 | (e.g. if the transferred files are few, small, or missing), it now |
| 1077 | periodically flushes the output buffer so that the sender/receiver |
| 1078 | can get started on the files sooner rather than later. |
| 1079 | |
| 1080 | - Improved the keep-alive code to handle a long silence between the |
| 1081 | sender and the receiver that can occur when the sender is receiving |
| 1082 | the checksum data for a large file. |
| 1083 | |
| 1084 | - Improved the auth-errors that are logged by the daemon to include |
| 1085 | some information on why the authorization failed: wrong user, |
| 1086 | password mismatch, etc. (The client-visible message is unchanged!) |
| 1087 | |
| 1088 | - Improved the client's handling of an "@ERROR" from a daemon so that |
| 1089 | it does not complain about an unexpectedly closed socket (since we |
| 1090 | really did expect the socket to close). |
| 1091 | |
| 1092 | - If the daemon can't open the log-file specified in rsyncd.conf, fall |
| 1093 | back to using syslog and log an appropriate warning. This is better |
| 1094 | than what was typically a totally silent (and fatal) failure (since a |
| 1095 | daemon is not usually run with the --no-detach option that was |
| 1096 | necessary to see the error on stderr). |
| 1097 | |
| 1098 | - The man pages now consistently refer to an rsync daemon as a "daemon" |
| 1099 | instead of a "server" (to distinguish it from the server process in a |
| 1100 | non-daemon transfer). |
| 1101 | |
| 1102 | - Made a small change to the rrsync script (restricted rsync -- in the |
| 1103 | support dir) to make a read-only server reject all --remove-* options |
| 1104 | when sending files (to future-proof it against the possibility of |
| 1105 | other similar options being added at some point). |
| 1106 | |
| 1107 | INTERNAL: |
| 1108 | |
| 1109 | - Rsync now calls setlocale(LC_CTYPE, ""). This enables isprint() to |
| 1110 | better discern which filename characters need to be escaped in |
| 1111 | messages (which should result in fewer escaped characters in some |
| 1112 | locales). |
| 1113 | |
| 1114 | - Improved the naming of the log-file open/reopen/close functions. |
| 1115 | |
| 1116 | - Removed some protocol-compatibility code that was only needed to help |
| 1117 | someone running a pre-release of 2.6.4. |
| 1118 | |
| 1119 | BUILD CHANGES: |
| 1120 | |
| 1121 | - Added configure option "--disable-locale" to disable any use of |
| 1122 | setlocale() in the binary. |
| 1123 | |
| 1124 | - Fixed a bug in the SUPPORT{,_HARD}_LINKS #defines which prevented |
| 1125 | rsync from being built without symlink or hard-link support. |
| 1126 | |
| 1127 | - Only #define HAVE_REMSH if it is going to be set to 1. |
| 1128 | |
| 1129 | - Configure now disables the use of mkstemp() under HP-UX (since they |
| 1130 | refuse to fix its broken handling of large files). |
| 1131 | |
| 1132 | - Configure now explicitly checks for the lseek64() function so that |
| 1133 | the code can use HAVE_LSEEK64 instead of inferring lseek64()'s |
| 1134 | presence based on the presence of the off64_t type. |
| 1135 | |
| 1136 | - Configure no longer mentions the change in the default remote-shell |
| 1137 | (from rsh to ssh) that occurred for the 2.6.0 release. |
| 1138 | |
| 1139 | - Some minor enhancements to the test scripts. |
| 1140 | |
| 1141 | - Added a few new *.diff files to the patches dir, including a patch |
| 1142 | that enables the optional copying of extended attributes. |

| 1145 | NEWS for rsync 2.6.4 (30 March 2005) |
| 1146 | Protocol: 29 (changed) |
| 1147 | Changes since 2.6.3: |
| 1148 | |
| 1149 | OUTPUT CHANGES: |
| 1150 | |
| 1151 | - When rsync deletes a directory and outputs a verbose message about |
| 1152 | it, it now appends a trailing slash to the name instead of (only |
| 1153 | sometimes) outputting a preceding "directory " string. |
| 1154 | |
| 1155 | - The --stats output will contain file-list time-statistics if both |
| 1156 | sides are 2.6.4, or if the local side is 2.6.4 and the files are |
| 1157 | being pushed (since the stats come from the sending side). |
| 1158 | (Requires protocol 29 for a pull.) |
| 1159 | |
| 1160 | - The "%o" (operation) log-format escape now has a third value (besides |
| 1161 | "send" and "recv"): "del." (with trailing dot to make it 4 chars). |
| 1162 | This changes the way deletions are logged in the daemon's log file. |
| 1163 | |
| 1164 | - When the --log-format option is combined with --verbose, rsync now |
| 1165 | avoids outputting the name of the file twice in most circumstances. |
| 1166 | As long as the --log-format item does not refer to any post-transfer |
| 1167 | items (such as %b or %c), the --log-format message is output prior to |
| 1168 | the transfer, so --verbose is now the equivalent of a --log-format of |
| 1169 | '%n%L' (which outputs the name and any link info). If the log output |
| 1170 | must occur after the transfer to be complete, the only time the name |
| 1171 | is also output prior to the transfer is when --progress was specified |
| 1172 | (so that the name will precede the progress stats, and the full |
| 1173 | --log-format output will come after). |
| 1174 | |
| 1175 | - Non-printable characters in filenames are replaced with a '?' to |
| 1176 | avoid corrupting the screen or generating empty lines in the output. |
| 1177 | |
| 1178 | BUG FIXES: |
| 1179 | |
| 1180 | - Restore the list-clearing behavior of "!" in a .cvsignore file (2.6.3 |
| 1181 | was only treating it as a special token in an rsync include/exclude |
| 1182 | file). |
| 1183 | |
| 1184 | - The combination of --verbose and --dry-run now mentions the full list |
| 1185 | of changes that would be output without --dry-run. |
| 1186 | |
| 1187 | - Avoid a mkdir warning when removing a directory in the destination |
| 1188 | that already exists in the --backup-dir. |
| 1189 | |
| 1190 | - An OS that has a binary mode for its files (such as cygwin) needed |
| 1191 | setmode(fd, O_BINARY) called on the temp-file we opened with |
| 1192 | mkstemp(). (Fix derived from cygwin's 2.6.3 rsync package.) |
| 1193 | |
| 1194 | - Fixed a potential hang when verbosity is high, the client side is |
| 1195 | the sender, and the file-list is large. |
| 1196 | |
| 1197 | - Fixed a potential protocol-corrupting bug where the generator could |
| 1198 | merge a message from the receiver into the middle of a multiplexed |
| 1199 | packet of data if only part of that data had been written out to the |
| 1200 | socket when the message from the generator arrived. |
| 1201 | |
| 1202 | - We now check if the OS doesn't support using mknod() for creating |
| 1203 | FIFOs and sockets, and compile-in some compatibility code using |
| 1204 | mkfifo() and socket() when necessary. |
| 1205 | |
| 1206 | - Fixed an off-by-one error in the handling of --max-delete=N. Also, |
| 1207 | if the --max-delete limit is exceeded during a run, we now output a |
| 1208 | warning about this at the end of the run and exit with a new error |
| 1209 | code (25). |
| 1210 | |
| 1211 | - One place in the code wasn't checking if fork() failed. |
| 1212 | |
| 1213 | - The "ignore nonreadable" daemon parameter used to erroneously affect |
| 1214 | readable symlinks that pointed to a non-existent file. |
| 1215 | |
| 1216 | - If the OS does not have lchown() and a chown() of a symlink will |
| 1217 | affect the referent of a symlink (as it should), we no longer try |
| 1218 | to set the user and group of a symlink. |
| 1219 | |
| 1220 | - The generator now properly runs the hard-link loop and the dir-time |
| 1221 | rewriting loop after we're sure that the redo phase is complete. |
| 1222 | |
| 1223 | - When --backup was specified with --partial-dir=DIR, where DIR is a |
| 1224 | relative path, the backup code was erroneously trying to backup a |
| 1225 | file that was put into the partial-dir. |
| 1226 | |
| 1227 | - If a file gets resent in a single transfer and the --backup option is |
| 1228 | enabled along with --inplace, rsync no longer performs a duplicate |
| 1229 | backup (it used to overwrite the first backup with the failed file). |
| 1230 | |
| 1231 | - One call to flush_write_file() was not being checked for an error. |
| 1232 | |
| 1233 | - The --no-relative option was not being sent from the client to a |
| 1234 | server sender. |
| 1235 | |
| 1236 | - If an rsync daemon specified "dont compress = ..." for a file and the |
| 1237 | client tried to specify --compress, the libz code was not handling a |
| 1238 | compression level of 0 properly. This could cause a transfer failure |
| 1239 | if the block-size for a file was large enough (e.g. rsync might have |
| 1240 | exited with an error for large files). |
| 1241 | |
| 1242 | - Fixed a bug that would sometimes surface when using --compress and |
| 1243 | sending a file with a block-size larger than 64K (either manually |
| 1244 | specified, or computed due to the file being really large). Prior |
| 1245 | versions of rsync would sometimes fail to decompress the data |
| 1246 | properly, and thus the transferred file would fail its verification. |
| 1247 | |
| 1248 | - If a daemon can't open the specified log file (i.e. syslog is not |
| 1249 | being used), die without crashing. We also output an error about |
| 1250 | the failure on stderr (which will only be seen if --no-detach was |
| 1251 | specified) and exit with a new error code (6). |
| 1252 | |
| 1253 | - A local transfer no longer duplicates all its include/exclude options |
| 1254 | (since the forked process already has a copy of the exclude list, |
| 1255 | there's no need to send them a set of duplicates). |
| 1256 | |
| 1257 | - The output of the items that are being updated by the generator (dirs, |
| 1258 | symlinks, devices) is now intermingled in the proper order with the |
| 1259 | output from the items that the receiver is updating (regular files) |
| 1260 | when pulling. This misordering was particularly bad when --progress |
| 1261 | was specified. (Requires protocol 29.) |
| 1262 | |
| 1263 | - When --timeout is specified, lulls that occur in the transfer while |
| 1264 | the generator is doing work that does not generate socket traffic |
| 1265 | (looking for changed files, deleting files, doing directory-time |
| 1266 | touch-ups, etc.) will cause a new keep-alive packet to be sent that |
| 1267 | should keep the transfer going as long as the generator continues to |
| 1268 | make progress. (Requires protocol 29.) |
| 1269 | |
| 1270 | - The stat size of a device is not added to the total file size of the |
| 1271 | items in the transfer (the size might be undefined on some OSes). |
| 1272 | |
| 1273 | - Fixed a problem with refused-option messages sometimes not making it |
| 1274 | back to the client side when a remote --files-from was in effect and |
| 1275 | the daemon was the receiver. |
| 1276 | |
| 1277 | - The --compare-dest option was not updating a file that differed in |
| 1278 | (the preserved) attributes from the version in the compare-dest DIR. |
| 1279 | |
| 1280 | - When rsync is copying files into a write-protected directory, fixed |
| 1281 | the change-report output for the directory so that we don't report |
| 1282 | an identical directory as changed. |
| 1283 | |
| 1284 | ENHANCEMENTS: |
| 1285 | |
| 1286 | - Rsync now supports popt's option aliases, which means that you can |
| 1287 | use /etc/popt and/or ~/.popt to create your own option aliases. |
| 1288 | |
| 1289 | - Added the --delete-during (--del) option which will delete files |
| 1290 | from the receiving side incrementally as each directory in the |
| 1291 | transfer is being processed. This makes it more efficient than the |
| 1292 | default, before-the-transfer behavior, which is now also available as |
| 1293 | --delete-before (and is still the default --delete-WHEN option that |
| 1294 | will be chosen if --delete or --delete-excluded is specified without |
| 1295 | a --delete-WHEN choice). All the --del* options infer --delete, so |
| 1296 | an rsync daemon that refuses "delete" will still refuse to allow any |
| 1297 | file-deleting options (including the new --remove-sent-files option). |
| 1298 | |
| 1299 | - All the --delete-WHEN options are now more memory efficient: |
| 1300 | Previously an duplicate set of file-list objects was created on the |
| 1301 | receiving side for the entire destination hierarchy. The new |
| 1302 | algorithm only creates one directory of objects at a time (for files |
| 1303 | inside the transfer). |
| 1304 | |
| 1305 | - Added the --copy-dest option, which works like --link-dest except |
| 1306 | that it locally copies identical files instead of hard-linking them. |
| 1307 | |
| 1308 | - Added support for specifying multiple --compare-dest, --copy-dest, or |
| 1309 | --link-dest options, but only of a single type. (Promoted from the |
| 1310 | patches dir and enhanced.) (Requires protocol 29.) |
| 1311 | |
| 1312 | - Added the --max-size option. (Promoted from the patches dir.) |
| 1313 | |
| 1314 | - The daemon-mode options are now separated from the normal rsync |
| 1315 | options so that they can't be mixed together. This makes it |
| 1316 | impossible to start a daemon that has improper default option values |
| 1317 | (which could cause problems when a client connects, such as hanging |
| 1318 | or crashing). |
| 1319 | |
| 1320 | - The --bwlimit option may now be used in combination with --daemon |
| 1321 | to specify both a default value for the daemon side and a value |
| 1322 | that cannot be exceeded by a user-specified --bwlimit option. |
| 1323 | |
| 1324 | - Added the "port" parameter to the rsyncd.conf file. (Promoted from |
| 1325 | the patches dir.) Also added "address". The command-line options |
| 1326 | take precedence over a config-file option, as expected. |
| 1327 | |
| 1328 | - In _exit_cleanup(): when we are exiting with a partially-received |
| 1329 | file, we now flush any data in the write-cache before closing the |
| 1330 | partial file. |
| 1331 | |
| 1332 | - The --inplace support was enhanced to work with --compare-dest, |
| 1333 | --link-dest, and (the new) --copy-dest options. (Requires protocol |
| 1334 | 29.) |
| 1335 | |
| 1336 | - Added the --dirs (-d) option for an easier way to copy directories |
| 1337 | without recursion. Any directories that are encountered are created |
| 1338 | on the destination. Specifying a directory with a trailing slash |
| 1339 | copies its immediate contents to the destination. |
| 1340 | |
| 1341 | - The --files-from option now implies --dirs (-d). |
| 1342 | |
| 1343 | - Added the --list-only option, which is mainly a way for the client to |
| 1344 | put the server into listing mode without needing to resort to any |
| 1345 | internal option kluges (e.g. the age-old use of "-r --exclude="/*/*" |
| 1346 | for a non-recursive listing). This option is used automatically |
| 1347 | (behind the scenes) when a modern rsync speaks to a modern daemon, |
| 1348 | but may also be specified manually if you want to force the use of |
| 1349 | the --list-only option over a remote-shell connection. |
| 1350 | |
| 1351 | - Added the --omit-dir-times (-O) option, which will avoid updating |
| 1352 | the modified time for directories when --times was specified. This |
| 1353 | option will avoid an extra pass through the file-list at the end of |
| 1354 | the transfer (to tweak all the directory times), which may provide |
| 1355 | an appreciable speedup for a really large transfer. (Promoted from |
| 1356 | the patches dir.) |
| 1357 | |
| 1358 | - Added the --filter (-f) option and its helper option, -F. Filter |
| 1359 | rules are an extension to the existing include/exclude handling |
| 1360 | that also supports nested filter files as well as per-directory |
| 1361 | filter files (like .cvsignore, but with full filter-rule parsing). |
| 1362 | This new option was chosen in order to ensure that all existing |
| 1363 | include/exclude processing remained 100% compatible with older |
| 1364 | versions. Protocol 29 is needed for full filter-rule support, but |
| 1365 | backward-compatible rules work with earlier protocol versions. |
| 1366 | (Promoted from the patches dir and enhanced.) |
| 1367 | |
| 1368 | - Added the --delay-updates option that puts all updated files into |
| 1369 | a temporary directory (by default ".~tmp~", but settable via the |
| 1370 | --partial-dir=DIR option) until the end of the transfer. This |
| 1371 | makes the updates a little more atomic for a large transfer. |
| 1372 | |
| 1373 | - If rsync is put into the background, any output from --progress is |
| 1374 | reduced. |
| 1375 | |
| 1376 | - Documented the "max verbosity" setting for rsyncd.conf. (This |
| 1377 | setting was added a couple releases ago, but left undocumented.) |
| 1378 | |
| 1379 | - The sender and the generator now double-check the file-list index |
| 1380 | they are given, and refuse to try to do a file transfer on a |
| 1381 | non-file index (since that would indicate that something had gone |
| 1382 | very wrong). |
| 1383 | |
| 1384 | - Added the --itemize-changes (-i) option, which is a way to output a |
| 1385 | more detailed list of what files changed and in what way. The effect |
| 1386 | is the same as specifying a --log-format of "%i %n%L" (see both the |
| 1387 | rsync and rsyncd.conf manpages). Works with --dry-run too. |
| 1388 | |
| 1389 | - Added the --fuzzy (-y) option, which attempts to find a basis file |
| 1390 | for a file that is being created from scratch. The current algorithm |
| 1391 | only looks in the destination directory for the created file, but it |
| 1392 | does attempt to find a match based on size/mod-time (in case the file |
| 1393 | was renamed with no other changes) as well as based on a fuzzy |
| 1394 | name-matching algorithm. This option requires protocol 29 because it |
| 1395 | needs the new file-sorting order. (Promoted from patches dir and |
| 1396 | enhanced.) (Requires protocol 29.) |
| 1397 | |
| 1398 | - Added the --remove-sent-files option, which lets you move files |
| 1399 | between systems. |
| 1400 | |
| 1401 | - The hostname in HOST:PATH or HOST::PATH may now be an IPv6 literal |
| 1402 | enclosed in '[' and ']' (e.g. "[::1]"). (We already allowed IPv6 |
| 1403 | literals in the rsync://HOST:PORT/PATH format.) |
| 1404 | |
| 1405 | - When rsync recurses to build the file list, it no longer keeps open |
| 1406 | one or more directory handles from the dir's parent dirs. |
| 1407 | |
| 1408 | - When building under windows, the default for --daemon is now to |
| 1409 | avoid detaching, requiring the new --detach option to force rsync |
| 1410 | to detach. |
| 1411 | |
| 1412 | - The --dry-run option can now be combined with either --write-batch or |
| 1413 | --read-batch, allowing you to run a do-nothing test command to see |
| 1414 | what would happen without --dry-run. |
| 1415 | |
| 1416 | - The daemon's "read only" config item now sets an internal read_only |
| 1417 | variable that makes extra sure that no write/delete calls on the |
| 1418 | read-only side can succeed. |
| 1419 | |
| 1420 | - The log-format % escapes can now have a numeric field width in |
| 1421 | between the % and the escape letter (e.g. "%-40n %08p"). |
| 1422 | |
| 1423 | - Improved the option descriptions in the --help text. |
| 1424 | |
| 1425 | SUPPORT FILES: |
| 1426 | |
| 1427 | - Added atomic-rsync to the support dir: a perl script that will |
| 1428 | transfer some files using rsync, and then move the updated files into |
| 1429 | place all at once at the end of the transfer. Only works when |
| 1430 | pulling, and uses --link-dest and a parallel hierarchy of files to |
| 1431 | effect its update. |
| 1432 | |
| 1433 | - Added mnt-excl to the support dir: a perl script that takes the |
| 1434 | /proc/mounts file and translates it into a set of excludes that will |
| 1435 | exclude all mount points (even mapped mounts to the same disk). The |
| 1436 | excludes are made relative to the specified source dir and properly |
| 1437 | anchored. |
| 1438 | |
| 1439 | - Added savetransfer.c to the support dir: a C program that can make |
| 1440 | a copy of all the data that flows over the wire. This lets you test |
| 1441 | for data corruption (by saving the data on both the sending side and |
| 1442 | the receiving side) and provides one way to debug a protocol error. |
| 1443 | |
| 1444 | - Added rrsync to the support dir: this is an updated version of Joe |
| 1445 | Smith's restricted rsync perl script. This helps to ensure that only |
| 1446 | certain rsync commands can be run by an ssh invocation. |
| 1447 | |
| 1448 | INTERNAL: |
| 1449 | |
| 1450 | - Added better checking of the checksum-header values that come over |
| 1451 | the socket. |
| 1452 | |
| 1453 | - Merged a variety of file-deleting functions into a single function so |
| 1454 | that it is easier to maintain. |
| 1455 | |
| 1456 | - Improved the type of some variables (particularly blocksize vars) for |
| 1457 | consistency and proper size. |
| 1458 | |
| 1459 | - Got rid of the uint64 type (which we didn't need). |
| 1460 | |
| 1461 | - Use a slightly more compatible set of core #include directives. |
| 1462 | |
| 1463 | - Defined int32 in a way that ensures that the build dies if we can't |
| 1464 | find a variable with at least 32 bits. |
| 1465 | |
| 1466 | PROTOCOL DIFFERENCES FOR VERSION 29: |
| 1467 | |
| 1468 | - A 16-bit flag-word is transmitted after every file-list index. This |
| 1469 | indicates what is changing between the sender and the receiver. The |
| 1470 | generator now transmits an index and a flag-word to indicate when |
| 1471 | dirs and symlinks have changed (instead of producing a message), |
| 1472 | which makes the outputting of the information more consistent and |
| 1473 | less prone to screen corruption (because the local receiver/sender is |
| 1474 | now outputting all the file-change info messages). |
| 1475 | |
| 1476 | - If a file is being hard-linked, the ITEM_XNAME_FOLLOWS bit is enabled |
| 1477 | in the flag-word and the name of the file that was linked immediately |
| 1478 | follows in vstring format (see below). |
| 1479 | |
| 1480 | - If a file is being transferred with an alternate-basis file, the |
| 1481 | ITEM_BASIS_TYPE_FOLLOWS bit is enabled in the flag-word and a single |
| 1482 | byte follows, indicating what type of basis file was chosen. If that |
| 1483 | indicates that a fuzzy-match was selected, the ITEM_XNAME_FOLLOWS bit |
| 1484 | is set in the flag-word and the name of the match in vstring format |
| 1485 | follows the basis byte. A vstring is a variable length string that |
| 1486 | has its size written prior to the string, and no terminating null. |
| 1487 | If the string is from 1-127 bytes, the length is a single byte. If |
| 1488 | it is from 128-32767 bytes, the length is written as ((len >> 8) | |
| 1489 | 0x80) followed by (len % 0x100). |
| 1490 | |
| 1491 | - The sending of exclude names is done using filter-rule syntax. This |
| 1492 | means that all names have a prefixed rule indicator, even excludes |
| 1493 | (which used to be sent as a bare pattern, when possible). The -C |
| 1494 | option will include the per-dir .cvsignore merge file in the list of |
| 1495 | filter rules so it is positioned correctly (unlike in some older |
| 1496 | transfer scenarios). |
| 1497 | |
| 1498 | - Rsync sorts the filename list in a different way: it sorts the subdir |
| 1499 | names after the non-subdir names for each dir's contents, and it |
| 1500 | always puts a dir's contents immediately after the dir's name in the |
| 1501 | list. (Previously an item named "foo.txt" would sort in between |
| 1502 | directory "foo/" and "foo/bar".) |
| 1503 | |
| 1504 | - When talking to a protocol 29 rsync daemon, a list-only request |
| 1505 | is able to note this before the options are sent over the wire and |
| 1506 | the new --list-only option is included in the options. |
| 1507 | |
| 1508 | - When the --stats bytes are sent over the wire (or stored in a batch), |
| 1509 | they now include two elapsed-time values: one for how long it took to |
| 1510 | build the file-list, and one for how long it took to send it over the |
| 1511 | wire (each expressed in thousandths of a second). |
| 1512 | |
| 1513 | - When --delete-excluded is specified with some filter rules (AKA |
| 1514 | excludes), a client sender will now initiate a send of the rules to |
| 1515 | the receiver (older protocols used to omit the sending of excludes in |
| 1516 | this situation since there were no receiver-specific rules that |
| 1517 | survived --delete-excluded back then). Note that, as with all the |
| 1518 | filter-list sending, only items that are significant to the other |
| 1519 | side will actually be sent over the wire, so the filter-rule list |
| 1520 | that is sent in this scenario is often empty. |
| 1521 | |
| 1522 | - An index equal to the file-list count is sent as a keep-alive packet |
| 1523 | from the generator to the sender, which then forwards it on to the |
| 1524 | receiver. This normally invalid index is only a valid keep-alive |
| 1525 | packet if the 16-bit flag-word that follows it contains a single bit |
| 1526 | (ITEM_IS_NEW, which is normally an illegal flag to appear alone). |
| 1527 | |
| 1528 | - A protocol-29 batch file includes a bit for the setting of the --dirs |
| 1529 | option and for the setting of the --compress option. Also, the shell |
| 1530 | script created by --write-batch will use the --filter option instead |
| 1531 | of --exclude-from to capture any filter rules. |
| 1532 | |
| 1533 | BUILD CHANGES: |
| 1534 | |
| 1535 | - Handle an operating system that use mkdev() in place of makedev(). |
| 1536 | |
| 1537 | - Improved configure to better handle cross-compiling. |
| 1538 | |

| 1540 | NEWS for rsync 2.6.3 (30 Sep 2004) |
| 1541 | Protocol: 28 (unchanged) |
| 1542 | Changes since 2.6.2: |
| 1543 | |
| 1544 | SECURITY FIXES: |
| 1545 | |
| 1546 | - A bug in the sanitize_path routine (which affects a non-chrooted |
| 1547 | rsync daemon) could allow a user to craft a pathname that would get |
| 1548 | transformed into an absolute path for certain options (but not for |
| 1549 | file-transfer names). If you're running an rsync daemon with chroot |
| 1550 | disabled, *please upgrade*, ESPECIALLY if the user privs you run |
| 1551 | rsync under is anything above "nobody". |
| 1552 | |
| 1553 | OUTPUT CHANGES (ATTN: those using a script to parse the verbose output): |
| 1554 | |
| 1555 | - Please note that the 2-line footer (output when verbose) now uses the |
| 1556 | term "sent" instead of "wrote" and "received" instead of "read". If |
| 1557 | you are not parsing the numeric values out of this footer, a script |
| 1558 | would be better off using the empty line prior to the footer as the |
| 1559 | indicator that the verbose output is over. |
| 1560 | |
| 1561 | - The output from the --stats option was similarly affected to change |
| 1562 | "written" to "sent" and "read" to "received". |
| 1563 | |
| 1564 | - Rsync ensures that a filename that contains a newline gets mentioned |
| 1565 | with each newline transformed into a question mark (which prevents a |
| 1566 | filename from causing an empty line to be output). |
| 1567 | |
| 1568 | - The "backed up ..." message that is output when at least 2 --verbose |
| 1569 | options are specified is now the same both with and without the |
| 1570 | --backup-dir option. |
| 1571 | |
| 1572 | BUG FIXES: |
| 1573 | |
| 1574 | - Fixed a crash bug that might appear when --delete was used and |
| 1575 | multiple source directories were specified. |
| 1576 | |
| 1577 | - Fixed a 32-bit truncation of the file length when generating the |
| 1578 | checksums. |
| 1579 | |
| 1580 | - The --backup code no longer attempts to create some directories |
| 1581 | over and over again (generating warnings along the way). |
| 1582 | |
| 1583 | - Fixed a bug in the reading of the secrets file (by the daemon) and |
| 1584 | the password file (by the client): the files no longer need to be |
| 1585 | terminated by a newline for their content to be read in. |
| 1586 | |
| 1587 | - If a file has a read error on the sending side or the reconstructed |
| 1588 | data doesn't match the expected checksum (perhaps due to the basis |
| 1589 | file changing during the transfer), the receiver will no longer |
| 1590 | retain the resulting file unless the --partial option was specified. |
| 1591 | (Note: for the read-error detection to work, neither side can be |
| 1592 | older than 2.6.3 -- older receivers will always retain the file, and |
| 1593 | older senders don't tell the receiver that the file had a read |
| 1594 | error.) |
| 1595 | |
| 1596 | - If a file gets resent in a single transfer and the --backup option |
| 1597 | is enabled, rsync no longer performs a duplicate backup (it used to |
| 1598 | overwrite the original file in the backup area). |
| 1599 | |
| 1600 | - Files specified in the daemon's "exclude" or "exclude from" config |
| 1601 | items are now excluded from being uploaded (assuming that the module |
| 1602 | allows uploading at all) in addition to the old download exclusion. |
| 1603 | |
| 1604 | - Got rid of a potential hang in the receiver when near the end of a |
| 1605 | phase. |
| 1606 | |
| 1607 | - When using --backup without a --backup-dir, rsync no longer preserves |
| 1608 | the modify time on directories. This avoids confusing NFS. |
| 1609 | |
| 1610 | - When --copy-links (-L) is specified, we now output a separate error |
| 1611 | for a symlink that has no referent instead of claiming that a file |
| 1612 | "vanished". |
| 1613 | |
| 1614 | - The --copy-links (-L) option no longer has the side-effect of telling |
| 1615 | the receiving side to follow symlinks. See the --keep-dirlinks |
| 1616 | option (mentioned below) for a way to specify that behavior. |
| 1617 | |
| 1618 | - Error messages from the daemon server's option-parsing (such as |
| 1619 | refused options) are now successfully transferred back to the client |
| 1620 | (the server used to fail to send the message because the socket |
| 1621 | wasn't in the right state for the message to get through). |
| 1622 | |
| 1623 | - Most transfer errors that occur during a daemon transfer are now |
| 1624 | returned to the user in addition to being logged (some messages are |
| 1625 | intended to be daemon-only and are not affected by this). |
| 1626 | |
| 1627 | - Fixed a bug in the daemon authentication code when using one of the |
| 1628 | batch-processing options. |
| 1629 | |
| 1630 | - We try to work around some buggy IPv6 implementations that fail to |
| 1631 | implement IPV6_V6ONLY. This should fix the "address in use" error |
| 1632 | that some daemons get when running on an OS with a buggy IPv6 |
| 1633 | implementation. Also, if the new code gets this error, we might |
| 1634 | suggest that the user specify --ipv4 or --ipv6 (if we think it will |
| 1635 | help). |
| 1636 | |
| 1637 | - When the remote rsync dies, make a better effort to recover any error |
| 1638 | messages it may have sent before dying (the local rsync used to just |
| 1639 | die with a socket-write error). |
| 1640 | |
| 1641 | - When using --delete and a --backup-dir that contains files that are |
| 1642 | hard-linked to their destination equivalents, rsync now makes sure |
| 1643 | that removed files really get removed (avoids a really weird rename() |
| 1644 | behavior). |
| 1645 | |
| 1646 | - Avoid a bogus run-time complaint about a lack of 64-bit integers when |
| 1647 | the int64 type is defined as an off_t and it actually has 64-bits. |
| 1648 | |
| 1649 | - Added a configure check for open64() without mkstemp64() so that we |
| 1650 | can avoid using mkstemp() when such a combination is encountered. |
| 1651 | This bypasses a problem writing out large temp files on OSes such as |
| 1652 | AIX and HP-UX. |
| 1653 | |
| 1654 | - Fixed an age-old crash problem with --read-batch on a local copy |
| 1655 | (rsync was improperly assuming --whole-file for the local copy). |
| 1656 | |
| 1657 | - When --dry-run (-n) is used and the destination directory does not |
| 1658 | exist, rsync now produces a correct report of files that would be |
| 1659 | sent instead of dying with a chdir() error. |
| 1660 | |
| 1661 | - Fixed a bug that could cause a slow-to-connect rsync daemon to die |
| 1662 | with an error instead of waiting for the connection to finish. |
| 1663 | |
| 1664 | - Fixed an ssh interaction that could cause output to be lost when the |
| 1665 | user chose to combine the output of rsync's stdout and stderr (e.g. |
| 1666 | using the "2>&1"). |
| 1667 | |
| 1668 | - Fixed an option-parsing bug when --files-from got passed to a daemon. |
| 1669 | |
| 1670 | ENHANCEMENTS: |
| 1671 | |
| 1672 | - Added the --partial-dir=DIR option that lets you specify where to |
| 1673 | (temporarily) put a partially transferred file (instead of over- |
| 1674 | writing the destination file). E.g. --partial-dir=.rsync-partial |
| 1675 | Also added support for the RSYNC_PARTIAL_DIR environment variable |
| 1676 | that, when found, transforms a regular --partial option (such as |
| 1677 | the convenient -P option) into one that also specifies a directory. |
| 1678 | |
| 1679 | - Added --keep-dirlinks (-K), which allows you to symlink a directory |
| 1680 | onto another partition on the receiving side and have rsync treat it |
| 1681 | as matching a normal directory from the sender. |
| 1682 | |
| 1683 | - Added the --inplace option that tells rsync to write each destination |
| 1684 | file without using a temporary file. The matching of existing data |
| 1685 | in the destination file can be severely limited by this, but there |
| 1686 | are also cases where this is more efficient (such as appending data). |
| 1687 | Use only when needed (see the man page for more details). |
| 1688 | |
| 1689 | - Added the "write only" option for the daemon's config file. |
| 1690 | |
| 1691 | - Added long-option names for -4 and -6 (namely --ipv4 and --ipv6) |
| 1692 | and documented all these options in the man page. |
| 1693 | |
| 1694 | - Improved the handling of the --bwlimit option so that it's less |
| 1695 | bursty, more accurate, and works properly over a larger range of |
| 1696 | values. |
| 1697 | |
| 1698 | - The rsync daemon-over-ssh code now looks for SSH_CONNECTION and |
| 1699 | SSH2_CLIENT in addition to SSH_CLIENT to figure out the IP address. |
| 1700 | |
| 1701 | - Added the --checksum-seed=N option for advanced users. |
| 1702 | |
| 1703 | - Batch writing/reading has a brand-new implementation that is simpler, |
| 1704 | fixes a few weird problems with the old code (such as no longer |
| 1705 | sprinkling the batch files into different dirs or even onto different |
| 1706 | systems), and is much less intrusive into the code (making it easier |
| 1707 | to maintain for the future). The new code generates just one data |
| 1708 | file instead of three, which makes it possible to read the batch on |
| 1709 | stdin via a remote shell. Also, the old requirement of forcing the |
| 1710 | same fixed checksum-seed for all batch processing has been removed. |
| 1711 | |
| 1712 | - If an rsync daemon has a module set with "list = no" (which hides its |
| 1713 | presence in the list of available modules), a user that fails to |
| 1714 | authenticate gets the same "unknown module" error that they would get |
| 1715 | if the module were actually unknown (while still logging the real |
| 1716 | error to the daemon's log file). This prevents fishing for module |
| 1717 | names. |
| 1718 | |
| 1719 | - The daemon's "refuse options" config item now allows you to match |
| 1720 | option names using wildcards and/or the single-letter option names. |
| 1721 | |
| 1722 | - Each transferred file now gets its permissions and modified-time |
| 1723 | updated before the temp-file gets moved into place. Previously, the |
| 1724 | finished file would have a very brief window where its permissions |
| 1725 | disallowed all group and world access. |
| 1726 | |
| 1727 | - Added the ability to parse a literal IPv6 address in an "rsync:" URL |
| 1728 | (e.g. rsync://[2001:638:500:101::21]:873/module/dir). |
| 1729 | |
| 1730 | - The daemon's wildcard expanding code can now handle more than 1000 |
| 1731 | filenames (it's now limited by memory instead of having a hard-wired |
| 1732 | limit). |
| 1733 | |
| 1734 | INTERNAL: |
| 1735 | |
| 1736 | - Some cleanup in the exclude code has saved some per-exclude memory |
| 1737 | and made the code easier to maintain. |
| 1738 | |
| 1739 | - Improved the argv-overflow checking for a remote command that has a |
| 1740 | lot of args. |
| 1741 | |
| 1742 | - Use rsyserr() in the various places that were still calling rprintf() |
| 1743 | with strerror() as an arg. |
| 1744 | |
| 1745 | - If an rsync daemon is listening on multiple sockets (to handle both |
| 1746 | IPv4 and IPv6 to a single port), we now close all the unneeded file |
| 1747 | handles after we accept a connection (we used to close just one of |
| 1748 | them). |
| 1749 | |
| 1750 | - Optimized the handling of larger block sizes (rsync used to slow to a |
| 1751 | crawl if the block size got too large). |
| 1752 | |
| 1753 | - Optimized away a loop in hash_search(). |
| 1754 | |
| 1755 | - Some improvements to the sanitize_path() and clean_fname() functions |
| 1756 | makes them more efficient and produce better results (while still |
| 1757 | being compatible with the file-name cleaning that gets done on both |
| 1758 | sides when sending the file-list). |
| 1759 | |
| 1760 | - Got rid of alloc_sanitize_path() after adding a destination-buffer |
| 1761 | arg to sanitize_path() made it possible to put all the former's |
| 1762 | functionality into the latter. |
| 1763 | |
| 1764 | - The file-list that is output when at least 4 verbose options are |
| 1765 | specified reports the uid value on the sender even when rsync is |
| 1766 | not running as root (since we might be sending to a root receiver). |
| 1767 | |
| 1768 | BUILD CHANGES: |
| 1769 | |
| 1770 | - Added a "gen" target to rebuild most of the generated files, |
| 1771 | including configure, config.h.in, the man pages, and proto.h. |
| 1772 | |
| 1773 | - If "make proto" doesn't find some changes in the prototypes, the |
| 1774 | proto.h file is left untouched (its time-stamp used to always be |
| 1775 | updated). |
| 1776 | |
| 1777 | - The variable $STRIP (that is optionally set by the install-strip |
| 1778 | target's rule) was changed to $INSTALL_STRIP because some systems |
| 1779 | have $STRIP already set in the environment. |
| 1780 | |
| 1781 | - Fixed a build problem when SUPPORT_HARD_LINKS isn't defined. |
| 1782 | |
| 1783 | - When cross-compiling, the gettimeofday() function is now assumed to |
| 1784 | be a modern version that takes two-args (since we can't test it). |
| 1785 | |
| 1786 | DEVELOPER RELATED: |
| 1787 | |
| 1788 | - The scripts in the testsuite dir were cleaned up a bit and a few |
| 1789 | new tests added. |
| 1790 | |
| 1791 | - Some new diffs were added to the patches dir, and some accepted |
| 1792 | ones were removed. |

| 1795 | NEWS for rsync 2.6.2 (30 Apr 2004) |
| 1796 | Protocol: 28 (unchanged) |
| 1797 | Changes since 2.6.1: |
| 1798 | |
| 1799 | BUG FIXES: |
| 1800 | |
| 1801 | - Fixed a major bug in the sorting of the filenames when --relative |
| 1802 | is used for some sources (just sources such as "/" and "/*" were |
| 1803 | affected). This fix ensures that we ask for the right file-list |
| 1804 | item when requesting changes from the sender. |
| 1805 | |
| 1806 | - Rsync now checks the return value of the close() function to |
| 1807 | better report disk-full problems on an NFS file system. |
| 1808 | |
| 1809 | - Restored the old daemon-server behavior of logging error messages |
| 1810 | rather than returning them to the user. (A better long-term fix |
| 1811 | will be sought in the future.) |
| 1812 | |
| 1813 | - An obscure uninitialized-variable bug was fixed in the uid/gid |
| 1814 | code. (This bug probably had no ill effects.) |
| 1815 | |
| 1816 | BUILD CHANGES: |
| 1817 | |
| 1818 | - Got rid of the configure check for sys/sysctl.h (it wasn't used |
| 1819 | and was causing a problem on some systems). Also improved the |
| 1820 | broken-largefile-locking test to try to avoid failure due to an |
| 1821 | NFS build-dir. |
| 1822 | |
| 1823 | - Fixed a compile problem on systems that don't define |
| 1824 | AI_NUMERICHOST. |
| 1825 | |
| 1826 | - Fixed a compile problem in the popt source for compilers that |
| 1827 | don't support __attribute__. |
| 1828 | |
| 1829 | DEVELOPER RELATED: |
| 1830 | |
| 1831 | - Improved the testsuite's "merge" test to work on OSF1. |
| 1832 | |
| 1833 | - Two new diffs were added to the patches dir. |
| 1834 | |
| 1835 | \f |
| 1836 | NEWS for rsync 2.6.1 (26 Apr 2004) |
| 1837 | Protocol: 28 (changed) |
| 1838 | Changes since 2.6.0: |
| 1839 | |
| 1840 | SECURITY FIXES: |
| 1841 | |
| 1842 | - Paths sent to an rsync daemon are more thoroughly sanitized when |
| 1843 | chroot is not used. If you're running a non-read-only rsync |
| 1844 | daemon with chroot disabled, *please upgrade*, ESPECIALLY if the |
| 1845 | user privs you run rsync under is anything above "nobody". |
| 1846 | |
| 1847 | ENHANCEMENTS: |
| 1848 | |
| 1849 | - Lower memory use, more optimal transfer of data over the socket, |
| 1850 | and lower CPU usage (see the INTERNAL section for details). |
| 1851 | |
| 1852 | - The RSYNC_PROXY environment variable can now contain a |
| 1853 | "USER:PASS@" prefix before the "HOST:PORT" information. |
| 1854 | (Bardur Arantsson) |
| 1855 | |
| 1856 | - The --progress output now mentions how far along in the transfer |
| 1857 | we are, including both a count of files transferred and a |
| 1858 | percentage of the total file-count that we've processed. It also |
| 1859 | shows better current-rate-of-transfer and remaining-transfer-time |
| 1860 | values. |
| 1861 | |
| 1862 | - Documentation changes now attempt to describe some often mis- |
| 1863 | understood features more clearly. |
| 1864 | |
| 1865 | BUG FIXES: |
| 1866 | |
| 1867 | - When -x (--one-file-system) is combined with -L (--copy-links) or |
| 1868 | --copy-unsafe-links, no symlinked files are skipped, even if the |
| 1869 | referent file is on a different filesystem. |
| 1870 | |
| 1871 | - The --link-dest code now works properly for a non-root user when |
| 1872 | (1) the UIDs of the source and destination differ and -o was |
| 1873 | specified, or (2) when the group of the source can't be used on |
| 1874 | the destination and -g was specified. |
| 1875 | |
| 1876 | - Fixed a bug in the handling of -H (hard-links) that might cause |
| 1877 | the expanded PATH/NAME value of the current item to get |
| 1878 | overwritten (due to an expanded-name caching bug). |
| 1879 | |
| 1880 | - We now reset the "new data has been sent" flag at the start of |
| 1881 | each file we send. This makes sure that an interrupted transfer |
| 1882 | with the --partial option set doesn't keep a shorter temp file |
| 1883 | than the current basis file when no new data has been transferred |
| 1884 | over the wire for that file. |
| 1885 | |
| 1886 | - Fixed a byte-order problem in --batch-mode on big-endian machines. |
| 1887 | (Jay Fenlason) |
| 1888 | |
| 1889 | - When using --cvs-exclude, the exclude items we get from a |
| 1890 | per-directory's .cvsignore file once again only affect that one |
| 1891 | directory (not all following directories too). The items are also |
| 1892 | now properly word-split and parsed without any +/- prefix parsing. |
| 1893 | |
| 1894 | - When specifying the USER@HOST: prefix for a file, the USER part |
| 1895 | can now contain an '@', if needed (i.e. the last '@' is used to |
| 1896 | find the HOST, not the first). |
| 1897 | |
| 1898 | - Fixed some bugs in the handling of group IDs for non-root users: |
| 1899 | (1) It properly handles a group that the sender didn't have a name |
| 1900 | for (it would previously skip changing the group on any files in |
| 1901 | that group). (2) If --numeric-ids is used, rsync no longer |
| 1902 | attempts to set groups that the user doesn't have the permission |
| 1903 | to set. |
| 1904 | |
| 1905 | - Fixed the "refuse options" setting in the rsyncd.conf file. |
| 1906 | |
| 1907 | - Improved the -x (--one-file-system) flag's handling of any mount- |
| 1908 | point directories we encounter. It is both more optimal (in that |
| 1909 | it no longer does a useless scan of the contents of the mount- |
| 1910 | point dirs) and also fixes a bug where a remapped mount of the |
| 1911 | original filesystem could get discovered in a subdir we should be |
| 1912 | ignoring. |
| 1913 | |
| 1914 | - Rsync no longer discards a double-slash at the start of a filename |
| 1915 | when trying to open the file. It also no longer constructs names |
| 1916 | that start with a double slash (unless the user supplied them). |
| 1917 | |
| 1918 | - Path-specifying options to a daemon should now work the same with |
| 1919 | or without chroot turned on. Previously, such a option (such as |
| 1920 | --link-dest) would get its absolute path munged into a relative |
| 1921 | one if chroot was not on, making that setting fairly useless. |
| 1922 | Rsync now transforms the path into one that is based on the |
| 1923 | module's base dir when chroot is not enabled. |
| 1924 | |
| 1925 | - Fixed a compatibility problem interacting with older rsync |
| 1926 | versions that might send us an empty --suffix value without |
| 1927 | telling us that --backup-dir was specified. |
| 1928 | |
| 1929 | - The "hosts allow" option for a daemon-over-remote-shell process |
| 1930 | now has improved support for IPv6 addresses and a fix for systems |
| 1931 | that have a length field in their socket structs. |
| 1932 | |
| 1933 | - Fixed the ability to request an empty backup --suffix when sending |
| 1934 | files to an rsync daemon. |
| 1935 | |
| 1936 | - Fixed an option-parsing bug when --files-from was sent to a server |
| 1937 | sender. |
| 1938 | |
| 1939 | INTERNAL: |
| 1940 | |
| 1941 | - Most of the I/O is now buffered, which results in a pretty large |
| 1942 | speedup when running under MS Windows. (Craig Barratt) |
| 1943 | |
| 1944 | - Optimizations to the name-handling/comparing code have made some |
| 1945 | significant reductions in user-CPU time for large file sets. |
| 1946 | |
| 1947 | - Some cleanup of the variable types make the code more consistent. |
| 1948 | |
| 1949 | - Reduced memory requirements of hard link preservation. |
| 1950 | (J.W. Schultz) |
| 1951 | |
| 1952 | - Implemented a new algorithm for hard-link handling that speeds up |
| 1953 | the code significantly. (J.W. Schultz and Wayne Davison) |
| 1954 | |
| 1955 | - The --hard-link option now uses the first existing file in the |
| 1956 | group of linked files as the basis for the transfer. This |
| 1957 | prevents the sub-optimal transfer of a file's data when a new |
| 1958 | hardlink is added on the sending side and it sorts alphabetically |
| 1959 | earlier in the list than the files that are already present on the |
| 1960 | receiving side. |
| 1961 | |
| 1962 | - Dropped support for protocol versions less than 20 (2.3.0 released |
| 1963 | 15 Mar 1999) and activated warnings for protocols less than 25 |
| 1964 | (2.5.0 released 23 Aug 2001). (Wayne Davison and J.W. Schultz, |
| 1965 | severally) |
| 1966 | |
| 1967 | - More optimal data transmission for --hard-links (protocol 28). |
| 1968 | |
| 1969 | - More optimal data transmission for --checksum (protocol 28). |
| 1970 | |
| 1971 | - Less memory is used when --checksum is specified. |
| 1972 | |
| 1973 | - Less memory is used in the file list (a per-file savings). |
| 1974 | |
| 1975 | - The generator is now better about not modifying the file list |
| 1976 | during the transfer in order to avoid a copy-on-write memory |
| 1977 | bifurcation (on systems where fork() uses shared memory). |
| 1978 | Previously, rsync's shared memory would slowly become unshared, |
| 1979 | resulting in real memory usage nearly doubling on the receiving |
| 1980 | side by the end of the transfer. Now, as long as permissions |
| 1981 | are being preserved, the shared memory should remain that way |
| 1982 | for the entire transfer. |
| 1983 | |
| 1984 | - Changed hardlink info and file_struct + strings to use allocation |
| 1985 | pools. This reduces memory use for large file-sets and permits |
| 1986 | freeing memory to the OS. (J.W. Schultz) |
| 1987 | |
| 1988 | - The 2 pipes used between the receiver and generator processes |
| 1989 | (which are forked on the same machine) were reduced to 1 pipe and |
| 1990 | the protocol improved so that (1) it is now impossible to have the |
| 1991 | "redo" pipe fill up and hang rsync, and (2) trailing messages from |
| 1992 | the receiver don't get lost on their way through the generator |
| 1993 | over to the sender (which mainly affected hard-link messages and |
| 1994 | verbose --stats output). |
| 1995 | |
| 1996 | - Improved the internal uid/gid code to be more portable and a |
| 1997 | little more optimized. |
| 1998 | |
| 1999 | - The device numbers sent when using --devices are now sent as |
| 2000 | separate major/minor values with 32-bit accuracy (protocol 28). |
| 2001 | Previously, the copied devices were sent as a single 32-bit |
| 2002 | number. This will make inter-operation of 64-bit binaries more |
| 2003 | compatible with their 32-bit brethren (with both ends of the |
| 2004 | connection are using protocol 28). Note that optimizations in the |
| 2005 | binary protocol for sending the device numbers often results in |
| 2006 | fewer bytes being used than before, even though more precision is |
| 2007 | now available. |
| 2008 | |
| 2009 | - Some cleanup of the exclude/include structures and its code made |
| 2010 | things clearer (internally), simpler, and more efficient. |
| 2011 | |
| 2012 | - The reading & writing of the file-list in batch-mode is now |
| 2013 | handled by the same code that sends & receives the list over the |
| 2014 | wire. This makes it much easier to maintain. (Note that the |
| 2015 | batch code is still considered to be experimental.) |
| 2016 | |
| 2017 | BUILD CHANGES: |
| 2018 | |
| 2019 | - The configure script now accepts --with-rsyncd-conf=PATH to |
| 2020 | override the default value of the /etc/rsyncd.conf file. |
| 2021 | |
| 2022 | - Fixed configure bug when running "./configure --disable-ipv6". |
| 2023 | |
| 2024 | - Fixed compilation problem on Tru64 Unix (having to do with |
| 2025 | sockaddr.sa_len and sockaddr.sin_len). |
| 2026 | |
| 2027 | DEVELOPER RELATED: |
| 2028 | |
| 2029 | - Fixed "make test" bug when build dir is not the source dir. |
| 2030 | |
| 2031 | - Added a couple extra diffs in the "patches" dir, removed the ones |
| 2032 | that got applied, and rebuilt the rest. |

| 2035 | NEWS for rsync 2.6.0 (1 Jan 2004) |
| 2036 | Protocol: 27 (changed) |
| 2037 | Changes since 2.5.7: |
| 2038 | |
| 2039 | ENHANCEMENTS: |
| 2040 | |
| 2041 | * "ssh" is now the default remote shell for rsync. If you want to |
| 2042 | change this, configure like this: "./configure --with-rsh=rsh". |
| 2043 | |
| 2044 | * Added --files-from, --no-relative, --no-implied-dirs, and --from0. |
| 2045 | Note that --from0 affects the line-ending character for all the |
| 2046 | files read by the --*-from options. (Wayne Davison) |
| 2047 | |
| 2048 | * Length of csum2 is now per-file starting with protocol version |
| 2049 | 27. (J.W. Schultz) |
| 2050 | |
| 2051 | * Per-file dynamic block size is now sqrt(file length). The |
| 2052 | per-file checksum size is determined according to an algorithm |
| 2053 | provided by Donovan Baarda which reduces the probability of rsync |
| 2054 | algorithm corrupting data and falling back using the whole md4 |
| 2055 | checksums. (J.W. Schultz, Donovan Baarda) |
| 2056 | |
| 2057 | * The --stats option no longer includes the (debug) malloc summary |
| 2058 | unless the verbose option was specified at least twice. |
| 2059 | |
| 2060 | * Added a new error/warning code for when files vanish from the |
| 2061 | sending side. Made vanished source files not interfere with the |
| 2062 | file-deletion pass when --delete-after was specified. |
| 2063 | |
| 2064 | * Various trailing-info sections are now preceded by a newline. |
| 2065 | |
| 2066 | BUG FIXES: |
| 2067 | |
| 2068 | * Fixed several exclude/include matching bugs when using wild-cards. |
| 2069 | This has a several user-visible effects, all of which make the |
| 2070 | matching more consistent and intuitive. This should hopefully not |
| 2071 | cause anyone problems since it makes the matching work more like |
| 2072 | what people are expecting. (Wayne Davison) |
| 2073 | |
| 2074 | - A pattern with a "**" no longer causes a "*" to match slashes. |
| 2075 | For example, with "/*/foo/**", "foo" must be 2 levels deep. |
| 2076 | [If your string has BOTH "*" and "**" wildcards, changing the |
| 2077 | "*" wildcards to "**" will provide the old behavior in all |
| 2078 | versions.] |
| 2079 | |
| 2080 | - "**/foo" now matches at the base of the transfer (like /foo |
| 2081 | does). [Use "/**/foo" to get the old behavior in all versions.] |
| 2082 | |
| 2083 | - A non-anchored wildcard term floats to match beyond the base of |
| 2084 | the transfer. E.g. "CVS/R*" matches at the end of the path, |
| 2085 | just like the non-wildcard term "CVS/Root" does. [Use "/CVS/R*" |
| 2086 | to get the old behavior in all versions.] |
| 2087 | |
| 2088 | - Including a "**" in the match term causes it to be matched |
| 2089 | against the entire path, not just the name portion, even if |
| 2090 | there aren't any interior slashes in the term. E.g. "foo**bar" |
| 2091 | would exclude "/path/foo-bar" (just like before) as well as |
| 2092 | "/foo-path/baz-bar" (unlike before). [Use "foo*bar" to get the |
| 2093 | old behavior in all versions.] |
| 2094 | |
| 2095 | * The exclude list specified in the daemon's config file is now |
| 2096 | properly applied to the pulled items no matter how deep the |
| 2097 | user's file-args are in the source tree. (Wayne Davison) |
| 2098 | |
| 2099 | * For protocol version >= 27, mdfour_tail() is called when the |
| 2100 | block size (including checksum_seed) is a multiple of 64. |
| 2101 | Previously it was not called, giving the wrong MD4 checksum. |
| 2102 | (Craig Barratt) |
| 2103 | |
| 2104 | * For protocol version >= 27, a 64 bit bit counter is used in |
| 2105 | mdfour.c as required by the RFC. Previously only a 32 bit bit |
| 2106 | counter was used, causing incorrect MD4 file checksums for |
| 2107 | file sizes >= 512MB - 4. (Craig Barratt) |
| 2108 | |
| 2109 | * Fixed a crash bug when interacting with older rsync versions and |
| 2110 | multiple files of the same name are destined for the same dir. |
| 2111 | (Wayne Davison) |
| 2112 | |
| 2113 | * Keep tmp names from overflowing MAXPATHLEN. |
| 2114 | |
| 2115 | * Make --link-dest honor the absence of -p, -o, and -g. |
| 2116 | |
| 2117 | * Made rsync treat a trailing slash in the destination in a more |
| 2118 | consistent manner. |
| 2119 | |
| 2120 | * Fixed file I/O error detection. (John Van Essen) |
| 2121 | |
| 2122 | * Fixed bogus "malformed address {hostname}" message in rsyncd log |
| 2123 | when checking IP address against hostnames from "hosts allow" |
| 2124 | and "hosts deny" parameters in config file. |
| 2125 | |
| 2126 | * Print heap statistics when verbose >= 2 instead of when >= 1. |
| 2127 | |
| 2128 | * Fixed a compression (-z) bug when syncing a mostly-matching file |
| 2129 | that contains already-compressed data. (Yasuoka Masahiko and |
| 2130 | Wayne Davison) |
| 2131 | |
| 2132 | * Fixed a bug in the --backup code that could cause deleted files |
| 2133 | to not get backed up. |
| 2134 | |
| 2135 | * When the backup code makes new directories, create them with mode |
| 2136 | 0700 instead of 0755 (since the directory permissions in the |
| 2137 | backup tree are not yet copied from the main tree). |
| 2138 | |
| 2139 | * Call setgroups() in a more portable manner. |
| 2140 | |
| 2141 | * Improved file-related error messages to better indicate exactly |
| 2142 | what pathname failed. (Wayne Davison) |
| 2143 | |
| 2144 | * Fixed some bugs in the handling of --delete and --exclude when |
| 2145 | using the --relative (-R) option. (Wayne Davison) |
| 2146 | |
| 2147 | * Fixed bug that prevented regular files from replacing |
| 2148 | special files and caused a directory in --link-dest or |
| 2149 | --compare-dest to block the creation of a file with the |
| 2150 | same path. A directory still cannot be replaced by a |
| 2151 | regular file unless --delete specified. (J.W. Schultz) |
| 2152 | |
| 2153 | * Detect and report when open or opendir succeed but read and |
| 2154 | readdir fail caused by network filesystem issues and truncated |
| 2155 | files. (David Norwood, Michael Brown, J.W. Schultz) |
| 2156 | |
| 2157 | * Added a fix that should give ssh time to restore the tty settings |
| 2158 | if the user presses Ctrl-C at an ssh password prompt. |
| 2159 | |
| 2160 | INTERNAL: |
| 2161 | |
| 2162 | * Eliminated vestigial support for old versions that we stopped |
| 2163 | supporting. (J.W. Schultz) |
| 2164 | |
| 2165 | * Simplified some of the option-parsing code. (Wayne Davison) |
| 2166 | |
| 2167 | * Some cleanup made to the exclude code, as well as some new |
| 2168 | defines added to enhance readability. (Wayne Davison) |
| 2169 | |
| 2170 | * Changed the protocol-version code so that it can interact at a |
| 2171 | lower protocol level than the maximum supported by both sides. |
| 2172 | Added an undocumented option, --protocol=N, to force the value |
| 2173 | we advertise to the other side (primarily for testing purposes). |

| 2195 | * The --suffix option can now be used with --backup-dir. (Michael |
| 2196 | Zimmerman) |
| 2197 | |
| 2198 | * Combining "::" syntax with the --rsh/-e option now uses the |
| 2199 | specified remote-shell as a transport to talk to a (newly-spawned) |
| 2200 | server-daemon. This allows someone to use daemon features, such |
| 2201 | as modules, over a secure protocol, such as ssh. (JD Paul) |
| 2202 | |
| 2203 | * The rsync:// syntax for daemon connections is now accepted in the |

| 2205 | |
| 2206 | * If the file name given to --include-from or --exclude-from is "-", |
| 2207 | rsync will read from standard input. (J.W. Schultz) |
| 2208 | |

| 2211 | (J.W. Schultz) |
| 2212 | |

| 2217 | Middleton) |
| 2218 | |
| 2219 | * Properly support IPv6 addresses in the rsyncd.conf "hosts allow" |
| 2220 | and "hosts deny" fields. (Hideaki Yoshifuji) |
| 2221 | |
| 2222 | * Changed exclude file handling to permit DOS or MAC style line |

| 2227 | |
| 2228 | BUG FIXES: |

| 2231 | L. Allen, Martin Pool) |
| 2232 | |
| 2233 | * Generate each file's rolling-checksum data as we send it, not |
| 2234 | in a separate (memory-eating) pass before hand. This prevents |
| 2235 | timeout errors on really large files. (Stefan Nehlsen) |
| 2236 | |
| 2237 | * Fix compilation on Tru64. (Albert Chin, Zoong Pham) |
| 2238 | |
| 2239 | * Better handling of some client-server errors. (Martin Pool) |
| 2240 | |
| 2241 | * Fixed a crash that would occur when sending a list of files that |
| 2242 | contains a duplicate name (if it sorts to the end of the file |
| 2243 | list) and using --delete. (Wayne Davison) |
| 2244 | |
| 2245 | * Fixed the file-name duplicate-removal code when dealing with multiple |
| 2246 | dups in a row. (Wayne Davison) |
| 2247 | |
| 2248 | * Fixed a bug that caused rsync to lose the exit status of its child |
| 2249 | processes and sometimes return an exit code of 0 instead of showing |
| 2250 | an error. (David R. Staples, Dave Dykstra) |
| 2251 | |
| 2252 | * Fixed bug in --copy-unsafe-links that caused it to be completely |
| 2253 | broken. (Dave Dykstra) |
| 2254 | |
| 2255 | * Prevent infinite recursion in cleanup code under certain circumstances. |
| 2256 | (Sviatoslav Sviridov and Marc Espie) |
| 2257 | |

| 2259 | when --relative-paths/-R is set. (Craig Barratt) |

| 2269 | |

| 2275 | (Jos Backus) |
| 2276 | |
| 2277 | * Updated config.guess and config.sub to latest versions; this |

| 2292 | (Peter Breitenlohner, Greg Louis) |
| 2293 | |

| 2357 | and resulted in the wrong data being copied. |
| 2358 | |
| 2359 | * Fixed compilation errors on some systems caused by the use of |

| 2361 | |
| 2362 | * Fixed problem on systems such as Sunos4 that do not support realloc |
| 2363 | on a NULL pointer; error was "out of memory in flist_expand". |
| 2364 | |
| 2365 | * Fix for rsync server processes hanging around after the client |
| 2366 | unexpectedly disconnects. (Colin Walters) (Debian bug #128632) |

| 2385 | and added documentation in the man page (Jos Backus) |

| 2485 | * Merged UNC rsync+ patch to support creation of standalone patch |
| 2486 | sets. By Bert J. Dempsey and Debra Weiss, updated by Jos |
| 2487 | Backus. <http://www.ils.unc.edu/i2dsi/unc_rsync+.html> |
| 2488 | |
| 2489 | * IPv6 support based on a patch from KAME.net, on systems |
| 2490 | including modern versions of Linux, Solaris, and HP-UX. Also |
| 2491 | includes IPv6 compatibility functions for old OSs by the |
| 2492 | Internet Software Consortium, Paul Vixie, the OpenSSH |

| 2498 | included or excluded and why. |
| 2499 | |
| 2500 | * Many error messages have more friendly explanations and more |
| 2501 | details. |
| 2502 | |
| 2503 | * Manual page improvements plus scanty protocol documentation. |
| 2504 | |
| 2505 | * When running as --daemon in the background and using a "log |
| 2506 | file" rsyncd.conf directive, close the log file every time it is |
| 2507 | open when going to sleep on the socket. This allows the log |
| 2508 | file to get cleaned out by another process. |
| 2509 | |
| 2510 | * Change to using libpopt rather than getopt for processing |
| 2511 | options. This makes the code cleaner and the behaviour more |
| 2512 | consistent across platforms. popt is included and built if not |
| 2513 | installed on the platform. |
| 2514 | |
| 2515 | * More details in --version, including note about whether 64-bit |
| 2516 | files, symlinks and hardlinks are supported. |
| 2517 | |
| 2518 | * MD4 code may use less CPU cycles. |
| 2519 | |

| 2521 | explain that we do it in a secure way. |
| 2522 | |
| 2523 | * --whole-file is the default when source and target are on the |
| 2524 | local machine. |

| 2528 | * Fix for various bugs causing rsync to hang. |
| 2529 | |
| 2530 | * Attempt to fix Large File Summit support on AIX. |
| 2531 | |
| 2532 | * Attempt to fix error handling lockup bug. |
| 2533 | |
| 2534 | * Give a non-0 exit code if *any* of the files we have been asked |
| 2535 | to transfer fail to transfer. |
| 2536 | |
| 2537 | * For log messages containing ridiculously long strings that might |
| 2538 | overflow a buffer rsync no longer aborts, but rather prints an |
| 2539 | ellipsis at the end of the string. (Patch from Ed Santiago.) |
| 2540 | |
| 2541 | PLATFORMS: |
| 2542 | |
| 2543 | * Improved support for UNICOS (tested on Cray T3E and Cray SV1) |
| 2544 | |
| 2545 | * autoconf2.52 (or later) is now required to rebuild the autoconf |
| 2546 | scripts. It is not required to simply build rsync. |
