1.1.1.3 ! misho 1: NEWS for rsync 3.1.1 (22 Jun 2014)
! 2: Protocol: 31 (unchanged)
! 3: Changes since 3.1.0:
! 4:
! 5: BUG FIXES:
! 6:
! 7: - If the receiver gets bogus filenames from the sender (an unexpected
! 8: leading slash or a ".." infix dir), exit with an error. This prevents a
! 9: malicious sender from trying to inject filenames that would affect an
! 10: area outside the destination directories.
! 11:
! 12: - Fixed a failure to remove the partial-transfer temp file when interrupted
! 13: (and rsync is not saving the partial files).
! 14:
! 15: - Changed the chown/group/xattr-set order to avoid losing some security-
! 16: related xattr info (that would get cleared by a chown).
! 17:
! 18: - Fixed a bug in the xattr-finding code that could make a non-root-run
! 19: receiver not able to find some xattr numbers.
! 20:
! 21: - Fixed a bug in the early daemon protocol where a timeout failed to be
! 22: honored (e.g. if the remote side fails to send us the initial protocol
! 23: greeting).
! 24:
! 25: - Fixed unintended inclusion of commas in file numbers in the daemon log.
! 26:
! 27: - We once again send the 'f' sub-flag (of -e) to the server side so it
! 28: knows that we can handle incremental-recursion directory errors properly
! 29: in older protocols.
! 30:
! 31: - Fixed an issue with too-aggressive keep-alive messages causing a problem
! 32: for older rsync versions early in the transfer.
! 33:
! 34: - Fixed an incorrect message about backup-directory-creation when using
! 35: --dry-run and the backup dir is not an absolute path.
! 36:
! 37: - Fixed a bug where a failed deletion and/or a failed sender-side removal
! 38: would not affect the exit code.
! 39:
! 40: - Fixed a bug that caused a failure when combining --delete-missing-args
! 41: with --xattrs and/or --acls.
! 42:
! 43: - Fixed a strange dir_depth assertion error that was caused by empty-dir
! 44: removals and/or duplicate files in the transfer.
! 45:
! 46: - Fixed a problem with --info=progress2's output stats where rsync would
! 47: only update the stats at the end of each file's transfer. It now uses
! 48: the data that is flowing for the current file, making the stats more
! 49: accurate and less jumpy.
! 50:
! 51: - Fixed an itemize bug that affected the combo of --link-dest, -X, and -n.
! 52:
! 53: - Fixed a problem with delete messages not appearing in the log file when
! 54: the user didn't use --verbose.
! 55:
! 56: - Improve chunked xattr reading for OS X.
! 57:
! 58: - Removed an attempted hard-link xattr optimization that was causing a
! 59: transfer failure. This removal is flagged in the compatibility code, so
! 60: if a better fix can be discovered, we have a way to flip it on again.
! 61:
! 62: - Fixed a bug when the receiver is not configured to be able to hard link
! 63: symlimks/devices/special-file items but the sender sent some of these
! 64: items flagged as hard-linked.
! 65:
! 66: - We now generate a better error if the buffer overflows in do_mknod().
! 67:
! 68: - Fixed a problem reading more than 16 ACLs on some OSes.
! 69:
! 70: - Fixed the reading of the secrets file to avoid an infinite wait when
! 71: the username is missing.
! 72:
! 73: - Fixed a parsing problem in the --usermap/--groupmap options when using
! 74: MIN-MAX numbers.
! 75:
! 76: - Switched Cygwin back to using socketpair "pipes" to try to speed it up.
! 77:
! 78: - Added knowledge of a few new options to rrsync.
! 79:
! 80: ENHANCEMENTS:
! 81:
! 82: - Tweaked the temp-file naming when --temp-dir=DIR is used: the temp-file
! 83: names will not get a '.' prepended.
! 84:
! 85: - Added support for a new-compression idiom that does not compress all the
! 86: matching data in a transfer. This can help rsync to use less cpu when a
! 87: transfer has a lot of matching data, and also makes rsync compatible with
! 88: a non-bundled zlib. See the --new-compress and --old-compress options in
! 89: the manpage.
! 90:
! 91: - Added the support/rsync-no-vanished wrapper script.
! 92:
! 93: - Made configure more prominently mention when we failed to find yodl (in
! 94: case the user wants to be able to generate manpages from *.yo files).
! 95:
! 96: - Have manpage mention how a daemon's max-verbosity setting affects info
! 97: and debug options. Also added more clarification on backslash removals
! 98: for excludes that contain wildcards.
! 99:
! 100: - Have configure check if for the attr lib (for getxattr) for those systems
! 101: that need to link against it explicitly.
! 102:
! 103: - Change the early dir-creation logic to only use that idiom in an
! 104: inc-recursive copy that is preserving directory times. e.g. using
! 105: --omit-dir-times will avoid these early directories being created.
! 106:
! 107: - Fix a bug in cmp_time() that would return a wrong result if the 2 times
! 108: differed by an amount greater than what a time_t can hold.
! 109:
! 110: DEVELOPER RELATED:
! 111:
! 112: - We now include an example systemd file (in packaging/systemd).
! 113:
! 114: - Tweaked configure to make sure that any intended use of the included popt
! 115: and/or zlib code is put early in the CFLAGS.
! 116:
! 117: NEWS for rsync 3.1.0 (28 Sep 2013)
! 118: Protocol: 31 (changed)
! 119: Changes since 3.0.9:
! 120:
! 121: OUTPUT CHANGES:
! 122:
! 123: - Output numbers in 3-digit groups by default (e.g. 1,234,567). See the
! 124: --human-readable option for a way to turn it off. See also the daemon's
! 125: "log format" parameter and related command-line options (including
! 126: --out-format) for a modifier that can be used to request digit-grouping
! 127: or human-readable output in log escapes. (Note that log output is
! 128: unchanged by default.)
! 129:
! 130: - The --list-only option is now affected by the --human-readable setting.
! 131: It will display digit groupings by default, and unit suffixes if higher
! 132: levels of readability are requested. Also, the column width for the size
! 133: output has increased from 11 to 14 characters when human readability is
! 134: enabled. Use --no-h to get the old-style output and column size.
! 135:
! 136: - The output of the --progress option has changed: the string "xfer" was
! 137: shortened to "xfr", and the string "to-check" was shortened to "to-chk",
! 138: both designed to make room for the (by default) wider display of file
! 139: size numbers without making the total line-length longer. Also, when
! 140: incremental recursion is enabled, the string "ir-chk" will be used
! 141: instead of "to-chk" up until the incremental-recursion scan is done,
! 142: letting you know that the value to check and the total value will still
! 143: be increasing as new files are found.
! 144:
! 145: - Enhanced the --stats output: 1) to mention how many files were created
! 146: (protocol >= 28), 2) to mention how many files were deleted (a new line
! 147: for protocol 31, but only output when --delete is in effect), and 3) to
! 148: follow the file-count, created-count, and deleted-count with a subcount
! 149: list that shows the counts by type. The wording of the transferred count
! 150: has also changed so that it is clearer that it is only a count of regular
! 151: files.
! 152:
! 153: BUG FIXES:
! 154:
! 155: - Fixed a bug in the iconv code when EINVAL or EILSEQ is returned with a
! 156: full output buffer.
! 157:
! 158: - Fixed some rare bugs in --iconv processing that might cause a multibyte
! 159: character to get translated incorrectly.
! 160:
! 161: - Fixed a bogus "vanished file" error if some files were specified with
! 162: "./" prefixes and others were not.
! 163:
! 164: - Fixed a bug in --sparse where an extra gap could get inserted after a
! 165: partial write.
! 166:
! 167: - Changed the way --progress overwrites its prior output in order to make
! 168: it nearly impossible for the progress to get overwritten by an error.
! 169:
! 170: - Improved the propagation of abnormal-exit error messages. This should
! 171: help the client side to receive errors from the server when it is exiting
! 172: abnormally, and should also avoid dying with an "connection unexpectedly
! 173: closed" exit when the closed connection is really expected.
! 174:
! 175: - The sender now checks each file it plans to remove to ensure that it
! 176: hasn't changed from the first stat's info. This helps to avoid losing
! 177: file data when the user is not using the option in a safe manner.
! 178:
! 179: - Fixed a data-duplication bug in the compress option that made compression
! 180: less efficient. This improves protocol 31 onward, while behaving in a
! 181: compatible (buggy) manner with older rsync protocols.
! 182:
! 183: - When creating a temp-file, rsync is now a bit smarter about it dot-char
! 184: choices, which can fix a problem on OS X with names that start with "..".
! 185:
! 186: - Rsync now sets a cleanup flag for --inplace and --append transfers that
! 187: will flush the write buffer if the transfer aborts. This ensures that
! 188: more received data gets written out to the disk on an aborted transfer
! 189: (which is quite helpful on a slow, flaky connection).
! 190:
! 191: - The reads that map_ptr() now does are aligned on 1K boundaries. This
! 192: helps some filesystems and/or files that don't like unaligned reads.
! 193:
! 194: - Fix an issue in the msleep() function if time jumps backwards.
! 195:
! 196: - Fix daemon-server module-name splitting bug where an arg would get split
! 197: even if --protect-args was used.
! 198:
! 199: ENHANCEMENTS:
! 200:
! 201: - Added the --remote-option=OPT (-M OPT) command-line option that is useful
! 202: for things like sending a remote --log-file=FILE or --fake-super option.
! 203:
! 204: - Added the --info=FLAGS and --debug=FLAGS options to allow finer-grained
! 205: control over what is output. Added an extra type of --progress output
! 206: using --info=progress2.
! 207:
! 208: - The --msgs2stderr option can help with debugging rsync by allowing the
! 209: debug messages to get output to stderr rather than travel via the socket
! 210: protocol.
! 211:
! 212: - Added the --delete-missing-args and --ignore-missing-args options to
! 213: either delete or ignore user-specified files on the receiver that are
! 214: missing on the sender (normally the absence of user-specified files
! 215: generates an error).
! 216:
! 217: - Added a "T" (terabyte) category to the --human-readable size suffixes.
! 218:
! 219: - Added the --usermap/--groupmap/--chown options for manipulating file
! 220: ownership during the copy.
! 221:
! 222: - Added the "%C" escape to the log-output handling, which will output the
! 223: MD5 checksum of any transferred file, or all files if --checksum was
! 224: specified (when protocol 30 or above is in effect).
! 225:
! 226: - Added the "reverse lookup" parameter to the rsync daemon config file to
! 227: allow reverse-DNS lookups to be disabled.
! 228:
! 229: - Added a forward-DNS lookup for the daemon's hosts allow/deny config. Can
! 230: be disabled via "forward lookup" parameter (defaults to enabled).
! 231:
! 232: - Added a way for more than one group to be specified in the daemon's
! 233: config file, including a way to specify that you want all of the
! 234: specified user's groups without having to name them. Also changed the
! 235: daemon to complain about an inability to set explicitly-specified uid/gid
! 236: values, even when not run by a super-user.
! 237:
! 238: - The daemon now tries to send the user the error messages from the
! 239: pre-xfer exec script when it fails.
! 240:
! 241: - Improved the use of alt-dest options into an existing hierarchy of files:
! 242: If a match is found in an alt-dir, it takes precedence over an existing
! 243: file. (We'll need to wait for a future version before attribute-changes
! 244: on otherwise unchanged files are safe when using an existing hierarchy.)
! 245:
! 246: - Added per-user authorization options and group-authorization support to
! 247: the daemon's "auth users" parameter.
! 248:
! 249: - Added a way to reference environment variables in a daemon's config file
! 250: (using %VAR% references).
! 251:
! 252: - When replacing a non-dir with a symlink/hard-link/device/special-file,
! 253: the update should now be done in an atomic manner.
! 254:
! 255: - Avoid re-sending xattr info for hard-linked files w/the same xattrs
! 256: (protocol 31).
! 257:
! 258: - The backup code was improved to use better logic maintaining the backup
! 259: directory hierarchy. Also, when a file is being backed up, rsync tries
! 260: to hard-link it into place so that the upcoming replacement of the
! 261: destination file will be atomic (for the normal, non-inplace logic).
! 262:
! 263: - Added the ability to synchronize nano-second modified times.
! 264:
! 265: - Added a few more default suffixes for the "dont compress" settings.
! 266:
! 267: - Added the checking of the RSYNC_PROTECT_ARGS environment variable to allow
! 268: the default for the --protect-args command-line option to be overridden.
! 269:
! 270: - Added the --preallocate command-line option.
! 271:
! 272: - Allow --password-file=- to read the password from stdin (filename "-").
! 273:
! 274: - Rsync now comes packaged with an rsync-ssl helper script that can be
! 275: used to contact a remote rsync daemon using a piped-stunnel command.
! 276: It also includes an stunnel config file to run the server side to
! 277: support ssl daemon connections. See the packaging/lsb/rsync.spec
! 278: file for one way to package the resulting files. (Suggestions for
! 279: how to make this even easier to install & use are welcomed.)
! 280:
! 281: - Improved the speed of some --inplace updates when there are lots of
! 282: identical checksum blocks that end up being unusable.
! 283:
! 284: - Added the --outbuf=N|L|B option for choosing the output buffering.
! 285:
! 286: - Repeating the --fuzzy option now causes the code to look for fuzzy
! 287: matches inside alt-dest directories too.
! 288:
! 289: - The --chmod option now supports numeric modes, e.g. --chmod=644,D755
! 290:
! 291: - Added some Solaris xattr code.
! 292:
! 293: - Made an rsync daemon (the listening process) exit with a 0 status when
! 294: it was signaled to die. This helps launchd.
! 295:
! 296: - Improved the RSYNC_* environment variables for the pre-xfer exec script:
! 297: when a daemon is sent multiple request args, they are now joined into a
! 298: single return value (separated by spaces) so that the RSYNC_REQUEST
! 299: environment variable is accurate for any "pre-xfer exec". The values in
! 300: RSYNC_ARG# vars are no longer truncated at the "." arg (prior to the
! 301: request dirs/files), so that all the requested values are also listed
! 302: (separately) in RSYNC_ARG# variables.
! 303:
! 304: EXTRAS:
! 305:
! 306: - Added an "instant-rsyncd" script to the support directory, which makes
! 307: it easy to configure a simple rsync daemon in the current directory.
! 308:
! 309: - Added the "mapfrom" and "mapto" scripts to the support directory, which
! 310: makes it easier to do user/group mapping in a local transfer based on
! 311: passwd/group files from another machine.
! 312:
! 313: - There's a new, improved version of the lsh script in the support dir:
! 314: it's written in perl and supports -u without resorting to using sudo
! 315: (when run as root). The old shell version is now named lsh.sh.
! 316:
! 317: - There is a helper script named rsync-slash-strip in the support directory
! 318: for anyone that wants to change the way rsync handles args with trailing
! 319: slashes. (e.g. arg/ would get stripped to arg while arg/. would turn into
! 320: arg/).
! 321:
! 322: INTERNAL:
! 323:
! 324: - The I/O code was rewritten to be simpler and do bigger buffered reads
! 325: over the socket. The I/O between the receiver and the generator was
! 326: changed to be standard multiplexed-I/O (like that over the socket).
! 327:
! 328: - The sender tries to use any dead time while the generator is looking for
! 329: files to transfer in order to do sender-side directory scanning in a more
! 330: parallel manner.
! 331:
! 332: - A daemon can now inform a client about a daemon-configured timeout value
! 333: so that the client can assist in the keep-alive activity (protocol 31).
! 334:
! 335: - The filter code received some refactoring to make it more extendible, to
! 336: read better, and do better sanity checking.
! 337:
! 338: - Really big numbers are now output using our own big-num routine rather
! 339: than casting them to a double and using a %.0f conversion.
! 340:
! 341: - The pool_alloc library has received some minor improvements in alignment
! 342: handling.
! 343:
! 344: - Added init_stat_x() function to avoid duplication of acl/xattr init code.
! 345:
! 346: - The included zlib was upgraded from 1.2.3 to 1.2.8.
! 347:
! 348: - Rsync can now be compiled to use an unmodified zlib library instead of
! 349: the tweaked one that is included with rsync. This will eventually
! 350: become the default, at which point we'll start the countdown to removing
! 351: the included zlib. Until then, feel free to configure using:
! 352:
! 353: ./configure --with-included-zlib=no
! 354:
! 355: DEVELOPER RELATED:
! 356:
! 357: - Added more conditional debug output.
! 358:
! 359: - Fixed some build issues for android and minix.
! 360:
1.1.1.2 misho 361: NEWS for rsync 3.0.9 (23 Sep 2011)
362: Protocol: 30 (unchanged)
363: Changes since 3.0.8:
364:
365: BUG FIXES:
366:
367: - Fix a crash bug in checksum scanning when --inplace is used.
368:
369: - Fix a hang if a hard-linked file cannot be opened by the sender (e.g.
370: if it has no read permission).
371:
372: - Fix preservation of a symlink's system xattrs (e.g. selinux) on Linux.
373:
374: - Fix a memory leak in the xattr code.
375:
376: - Fixed a bug with --delete-excluded when a filter merge file has a rule
377: that specifies a receiver-only side restriction.
378:
379: - Fix a bug with the modifying of unwritable directories.
380:
381: - Fix --fake-super's interaction with --link-dest same-file comparisons.
382:
383: - Fix the updating of the curr_dir buffer to avoid a duplicate slash.
384:
385: - Fix the directory permissions on an implied dot-dir when using --relative
386: (e.g. /outside/path/././send/path).
387:
388: - Fixed some too-long sleeping instances when using --bwlimit.
389:
390: - Fixed when symlink ownership difference-checking gets compiled into
391: unchanged_attrs().
392:
393: - Improved the socket-error reporting when multiple protocols fail.
394:
395: - Fixed a case where a socket error could reference just-freed memory.
396:
397: - Failing to use a password file that was specified on the command-line is
398: now a fatal error.
399:
400: - Fix the non-root updating of directories that don't have the read and/or
401: execute permission.
402:
403: - Make daemon-excluded file errors more error-like.
404:
405: - Fix a compilation issue on older C compilers (due to a misplaced var
406: declaration).
407:
408: - Make configure avoid finding socketpair on cygwin.
409:
410: - Avoid trying to reference SO_BROADCAST if the OS doesn't support it.
411:
412: - Fix some issues with the post-processing of the man pages.
413:
414: - Fixed the user home-dir handling in the support/lsh script.
415:
416: - Some minor manpage improvements.
417:
1.1 misho 418: NEWS for rsync 3.0.8 (26 Mar 2011)
419: Protocol: 30 (unchanged)
420: Changes since 3.0.7:
421:
422: BUG FIXES:
423:
424: - Fixed two buffer-overflow issues: one where a directory path that is
425: exactly MAXPATHLEN was not handled correctly, and one handling a
426: --backup-dir that is extra extra large.
427:
428: - Fixed a data-corruption issue when preserving hard-links without
429: preserving file ownership, and doing deletions either before or during
430: the transfer (CVE-2011-1097). This fixes some assert errors in the
431: hard-linking code, and some potential failed checksums (via -c) that
432: should have matched.
433:
434: - Fixed a potential crash when an rsync daemon has a filter/exclude list
435: and the transfer is using ACLs or xattrs.
436:
437: - Fixed a hang if a really large file is being processed by an rsync that
438: can't handle 64-bit numbers. Rsync will now complain about the file
439: being too big and skip it.
440:
441: - For devices and special files, we now avoid gathering useless ACL and/or
442: xattr information for files that aren't being copied. (The un-copied
443: files are still put into the file list, but there's no need to gather
444: data that is not going to be used.) This ensures that if the user uses
445: --no-D, that rsync can't possibly complain about being unable to gather
446: extended information from special files that are in the file list (but
447: not in the transfer).
448:
449: - Properly handle requesting remote filenames that start with a dash. This
450: avoids a potential error where a filename could be interpreted as a
451: (usually invalid) option.
452:
453: - Fixed a bug in the comparing of upper-case letters in file suffixes for
454: --skip-compress.
455:
456: - If an rsync daemon has a module configured without a path setting, rsync
457: will now disallow access to that module.
458:
459: - If the destination arg is an empty string, it will be treated as a
460: reference to the current directory (as 2.x used to do).
461:
462: - If rsync was compiled with a newer time-setting function (such as
463: lutimes), rsync will fall-back to an older function (such as utimes) on a
464: system where the newer function is not around. This helps to make the
465: rsync binary more portable in mixed-OS-release situations.
466:
467: - Fixed a batch-file writing bug that would not write out the full set of
468: compatibility flags that the transfer was using. This fixes a potential
469: protocol problem for a batch file that contains a sender-side I/O error:
470: it would have been sent in a way that the batch-reader wasn't expecting.
471:
472: - Some improvements to the hard-linking code to ensure that device-number
473: hashing is working right, and to supply more information if the hard-link
474: code fails.
475:
476: - The --inplace code was improved to not search for an impossible checksum
477: position. The quadruple-verbose chunk[N] message will now mention when
478: an inplace chunk was handled by a seek rather than a read+write.
479:
480: - Improved ACL mask handling, e.g. for Solaris.
481:
482: - Fixed a bug that prevented --numeric-ids from disabling the translation
483: of user/group IDs for ACLs.
484:
485: - Fixed an issue where an xattr and/or ACL transfer that used an alt-dest
486: option (e.g. --link-dest) could output an error trying to itemize the
487: changes against the alt-dest directory's xattr/ACL info but was instead
488: trying to access the not-yet-existing new destination directory.
489:
490: - Improved xattr system-error messages to mention the full path to the
491: file.
492:
493: - The --link-dest checking for identical symlinks now avoids considering
494: attribute differences that cannot be changed on the receiver.
495:
496: - Avoid trying to read/write xattrs on certain file types for certain OSes.
497: Improved configure to set NO_SYMLINK_XATTRS, NO_DEVICE_XATTRS, and/or
498: NO_SPECIAL_XATTRS defines in config.h.
499:
500: - Improved the unsafe-symlink errors messages.
501:
502: - Fixed a bug setting xattrs on new files that aren't user writable.
503:
504: - Avoid re-setting xattrs on a hard-linked file w/the same xattrs.
505:
506: - Fixed a bug with --fake-super when copying files and dirs that aren't
507: user writable.
508:
509: - Fixed a bug where a sparse file could have its last sparse block turned
510: into a real block when rsync sets the file size (requires ftruncate).
511:
512: - If a temp-file name is too long, rsync now avoids truncating the name in
513: the middle of adjacent high-bit characters. This prevents a potential
514: filename error if the filesystem doesn't allow a name to contain an
515: invalid multi-byte sequence.
516:
517: - If a muli-protocol socket connection fails (i.e., when contacting a
518: daemon), we now report all the failures, not just the last one. This
519: avoids losing a relevant error (e.g. an IPv4 connection-refused error)
520: that happened before the final error (e.g. an IPv6 protocol-not-supported
521: error).
522:
523: - Generate a transfer error if we try to call chown with a -1 for a uid or
524: a gid (which is not settable).
525:
526: - Fixed the working of --force when used with --one-file-system.
527:
528: - Fix the popt arg parsing so that an option that doesn't take an arg will
529: reject an attempt to supply one (can configure --with-included-popt if
530: your system's popt library doesn't yet have this fix).
531:
532: - A couple minor option tweaks to the support/rrsync script, and also some
533: regex changes that make vim highlighting happier.
534:
535: - Fixed some issues in the support/mnt-excl script.
536:
537: - Various manpage improvements.
538:
539: ENHANCEMENTS:
540:
541: - Added ".hg/" to the default cvs excludes (see -C & --cvs-exclude).
542:
543: DEVELOPER RELATED:
544:
545: - Use lchmod() whenever it is available (not just on symlinks).
546:
547: - A couple fixes to the socketpair_tcp() routine.
548:
549: - Updated the helper scripts in the packaging subdirectory.
550:
551: - Renamed configure.in to configure.ac.
552:
553: - Fixed configure's checking for iconv routines for newer OS X versions.
554:
555: - Fixed the testsuite/xattrs.test script on OS X.
556:
557: NEWS for rsync 3.0.7 (31 Dec 2009)
558: Protocol: 30 (unchanged)
559: Changes since 3.0.6:
560:
561: BUG FIXES:
562:
563: - Fixed a bogus free when using --xattrs with --backup.
564:
565: - Avoid an error when --dry-run was trying to stat a prior hard-link file
566: that hasn't really been created.
567:
568: - Fixed a problem with --compress (-z) where the receiving side could
569: return the error "inflate (token) returned -5".
570:
571: - Fixed a bug where --delete-during could delete in a directory before it
572: noticed that the sending side sent an I/O error for that directory (both
573: sides of the transfer must be at least 3.0.7).
574:
575: - Improved --skip-compress's error handling of bad character-sets and got
576: rid of a lingering debug fprintf().
577:
578: - Fixed the daemon's conveyance of io_error value from the sender.
579:
580: - An rsync daemon use seteuid() (when available) if it used setuid().
581:
582: - Get the permissions right on a --fake-super transferred directory that
583: needs more owner permissions to emulate root behavior.
584:
585: - An absolute-path filter rule (i.e. with a '/' modifier) no longer loses
586: its modifier when sending the filter rules to the remote rsync.
587:
588: - Improved the "--delete does not work without -r or -d" message.
589:
590: - Improved rsync's handling of --timeout to avoid a weird timeout case
591: where the sender could timeout even though it has recently written data
592: to the socket (but hasn't read data recently, due to the writing).
593:
594: - Some misc manpage improvements.
595:
596: - Fixed the chmod-temp-dir testsuite on a system without /var/tmp.
597:
598: - Make sure that a timeout specified in the daemon's config is used as a
599: maximum timeout value when the user also specifies a timeout.
600:
601: - Improved the error-exit reporting when rsync gets an error trying to
602: cleanup after an error: the initial error is reported.
603:
604: - Improved configure's detection of IPv6 for solaris and cygwin.
605:
606: - The AIX sysacls routines will now return ENOSYS if ENOTSUP is missing.
607:
608: - Made our (only used if missing) getaddrinfo() routine use inet_pton()
609: (which we also provide) instead of inet_aton().
610:
611: - The exit-related debug messages now mention the program's role so it is
612: clear who output what message.
613:
614: DEVELOPER RELATED:
615:
616: - Got rid of type-punned compiler warnings output by newer gcc versions.
617:
618: - The Makefile now ensures that proto.h will be rebuilt if config.h changes.
619:
620: - The testsuite no longer uses "id -u", so it works better on solaris.
621:
622:
623: NEWS for rsync 3.0.6 (8 May 2009)
624: Protocol: 30 (unchanged)
625: Changes since 3.0.5:
626:
627: BUG FIXES:
628:
629: - Fixed a --read-batch hang when rsync is reading a batch file that was
630: created from an incremental-recursion transfer.
631:
632: - Fixed the daemon's socket code to handle the simultaneous arrival of
633: multiple connections.
634:
635: - Fix --safe-links/--copy-unsafe-links to properly handle symlinks that
636: have consecutive slashes in the value.
637:
638: - Fixed the parsing of an [IPv6_LITERAL_ADDR] when a USER@ is prefixed.
639:
640: - The sender now skips a (bogus) symlink that has a 0-length value, which
641: avoids a transfer error in the receiver.
642:
643: - Fixed a case where the sender could die with a tag-0 error if there was
644: an I/O during the sending of the file list.
645:
646: - Fixed the rrsync script to avoid a server-side problem when -e is at the
647: start of the short options.
648:
649: - Fixed a problem where a vanished directory could turn into an exit code
650: 23 instead of the proper exit code 24.
651:
652: - Fixed the --iconv conversion of symlinks when doing a local copy.
653:
654: - Fixed a problem where --one-file-system was not stopping deletions on the
655: receiving side when a mount-point directory did not match a directory in
656: the transfer.
657:
658: - Fixed the dropping of an ACL mask when no named ACL values were present.
659:
660: - Fixed an ACL/xattr corruption issue where the --backup option could cause
661: rsync to associate the wrong ACL/xattr information with received files.
662:
663: - Fixed the use of --xattrs with --only-write-batch.
664:
665: - Fixed the use of --dry-run with --read-batch.
666:
667: - Fixed configure's erroneous use of target.
668:
669: - Fixed configure's --disable-debug option.
670:
671: - Fixed a run-time issue for systems that can't find iconv_open() by adding
672: the --disable-iconv-open configure option.
673:
674: - Complain and die if the user tries to combine --remove-source-files (or
675: the deprecated --remove-sent-files) with --read-batch.
676:
677: - Fixed an failure transferring special files from Solaris to Linux.
678:
679:
680: NEWS for rsync 3.0.5 (28 Dec 2008)
681: Protocol: 30 (unchanged)
682: Changes since 3.0.4:
683:
684: BUG FIXES:
685:
686: - Initialize xattr data in a couple spots in the hlink code, which avoids a
687: crash when the xattr pointer's memory happens to start out non-zero.
688: Also fixed the itemizing of an alt-dest file's xattrs when hard-linking.
689:
690: - Don't send a bogus "-" option to an older server if there were no short
691: options specified.
692:
693: - Fixed skipping of unneeded updates in a batch file when incremental
694: recursion is active. Added a test for this. Made batch-mode handle
695: "redo" files properly (and without hanging).
696:
697: - Fix the %P logfile escape when the daemon logs from inside a chroot.
698:
699: - Fixed the use of -s (--protect-args) when used with a remote source or
700: destination that had an empty path (e.g. "host:"). Also fixed a problem
701: when -s was used when accessing a daemon via a remote-shell.
702:
703: - Fixed the use of a dot-dir path (e.g. foo/./bar) inside a --files-from
704: file when the root of the transfer isn't the current directory.
705:
706: - Fixed a bug with "-K --delete" removing symlinks to directories when
707: incremental recursion is active.
708:
709: - Fixed a hard to trigger hang when using --remove-source-files.
710:
711: - Got rid of an annoying delay when accessing a daemon via a remote-shell.
712:
713: - Properly ignore (superfluous) source args on a --read-batch command.
714:
715: - Improved the manpage's description of the '*' wildcard to remove the
716: confusing "non-empty" qualifier.
717:
718: - Fixed reverse lookups in the compatibility-library version of
719: getnameinfo().
720:
721: - Fixed a bug when using --sparse on a sparse file that has over 2GB of
722: consecutive sparse data.
723:
724: - Avoid a hang when using at least 3 --verbose options on a transfer with a
725: client sender (which includes local copying).
726:
727: - Fixed a problem with --delete-delay reporting an error when it was ready
728: to remove a directory that was now gone.
729:
730: - Got rid of a bunch of "warn_unused_result" compiler warnings.
731:
732: - If an ftruncate() on a received file fails, it now causes a partial-
733: transfer warning.
734:
735: - Allow a path with a leading "//" to be preserved (CYGWIN only).
736:
737: ENHANCEMENTS:
738:
739: - Made the support/atomic-rsync script able to perform a fully atomic
740: update of the copied hierarchy when the destination is setup using a
741: particular symlink idiom.
742:
743:
744: NEWS for rsync 3.0.4 (6 Sep 2008)
745: Protocol: 30 (unchanged)
746: Changes since 3.0.3:
747:
748: BUG FIXES:
749:
750: - Fixed a bug in the hard-linking code where it would sometimes try to
751: allocate 0 bytes of memory (which fails on some OSes, such as AIX).
752:
753: - Fixed the hard-linking of files from a device that has a device number
754: of 0 (which seems to be a common device number on NetBSD).
755:
756: - Fixed the handling of a --partial-dir that cannot be created. This
757: particularly impacts the --delay-updates option (since the files cannot
758: be delayed without a partial-dir), and was potentially destructive if
759: the --remove-source-files was also specified.
760:
761: - Fixed a couple issues in the --fake-super handling of xattrs when the
762: destination files have root-level attributes (e.g. selinux values) that
763: a non-root copy can't affect.
764:
765: - Improved the keep-alive check in the generator to fire consistently in
766: incremental-recursion mode when --timeout is enabled.
767:
768: - The --iconv option now converts the content of a symlink too, instead
769: of leaving it in the wrong character-set (requires 3.0.4 on both sides
770: of the transfer).
771:
772: - When using --iconv, if a filename fails to convert on the receiving side,
773: this no longer makes deletions in the root-dir of the transfer fail
774: silently (the user now gets a warning about deletions being disabled
775: due to IO error as long as --ignore-errors was not specified).
776:
777: - When using --iconv, if a server-side receiver can't convert a filename,
778: the error message sent back to the client no longer mangles the name
779: with the wrong charset conversion.
780:
781: - Fixed a potential alignment issue in the IRIX ACL code when allocating
782: the initial "struct acl" object. Also, cast mallocs to avoid warnings.
783:
784: - Changed some errors that were going to stdout to go to stderr.
785:
786: - Made human_num() and human_dnum() able to output a negative number
787: (rather than outputting a cryptic string of punctuation).
788:
789: ENHANCEMENTS:
790:
791: - Rsync will avoid sending an -e option to the server if an older protocol
792: is requested (and thus the option would not be useful). This lets the
793: user specify the --protocol=29 option to access an overly-restrictive
794: server that is rejecting the protocol-30 use of -e to the server.
795:
796: - Improved the message output for an RERR_PARTIAL exit.
797:
798: DEVELOPER RELATED:
799:
800: - The Makefile will not halt for just a timestamp change on the Makefile
801: or the configure files, only for actual changes in content.
802:
803: - Changed some commands in the testsuite's xattrs.test that called "rsync"
804: instead of "$RSYNC".
805:
806: - Enhanced the release scripts to be able to handle a branch release and
807: to do even more consistency checks on the files.
808:
809:
810: NEWS for rsync 3.0.3 (29 Jun 2008)
811: Protocol: 30 (unchanged)
812: Changes since 3.0.2:
813:
814: BUG FIXES:
815:
816: - Fixed a wildcard matching problem in the daemon when a module has
817: "use chroot" enabled.
818:
819: - Fixed a crash bug in the hard-link code.
820:
821: - Fixed the sending of xattr directory information when the code finds a
822: --link-dest or --copy-dest directory with unchanged xattrs -- the
823: destination directory now gets these unchanged xattrs properly applied.
824:
825: - Fixed an xattr-sending glitch that could cause an "Internal abbrev"
826: error.
827:
828: - Fixed the combination of --xattrs and --backup.
829:
830: - The generator no longer allows a '.' dir to be excluded by a daemon-
831: exclude rule.
832:
833: - Fixed deletion handling when copying a single, empty directory (with no
834: files) to a differently named, non-existent directory.
835:
836: - Fixed the conversion of spaces into dashes in the %M log escape.
837:
838: - Fixed several places in the code that were not returning the right
839: errno when a function failed.
840:
841: - Fixed the backing up of a device or special file into a backup dir.
842:
843: - Moved the setting of the socket options prior to the connect().
844:
845: - If rsync exits in the middle of a --progress output, it now outputs a
846: newline to help prevent the progress line from being overwritten.
847:
848: - Fixed a problem with how a destination path with a trailing slash or
849: a trailing dot-dir was compared against the daemon excludes.
850:
851: - Fixed the sending of large (size > 16GB) files when talking to an older
852: rsync (protocols < 30): we now use a compatible block size limit.
853:
854: - If a file's length is so huge that we overflow a checksum buffer count
855: (i.e. several hundred TB), warn the user and avoid sending an invalid
856: checksum struct over the wire.
857:
858: - If a source arg is excluded, --relative no longer adds the excluded
859: arg's implied dirs to the transfer. This fix also made the exclude
860: check happen in the better place in the sending code.
861:
862: - Use the overflow_exit() function for overflows, not out_of_memory().
863:
864: - Improved the code to better handle a system that has only 32-bit file
865: offsets.
866:
867: ENHANCEMENTS:
868:
869: - The rsyncd.conf manpage now consistently refers to the parameters in
870: the daemon config file as "parameters".
871:
872: - The description of the --inplace option was improved.
873:
874: EXTRAS:
875:
876: - Added a new script in the support directory, deny-rsync, which allows
877: an admin to (temporarily) replace the rsync command with a script that
878: sends an error message to the remote client via the rsync protocol.
879:
880: DEVELOPER RELATED:
881:
882: - Fixed a testcase failure if the tests are run as root and made some
883: compatibility improvements.
884:
885: - Improved the daemon tests, including checking module comments, the
886: listing of files, and the ensuring that daemon excludes can't affect
887: a dot-dir arg.
888:
889: - Improved some build rules for those that build in a separate directory
890: from the source, including better install rules for the man pages, and
891: the fixing of a proto.h-tstamp rule that could make the binaries get
892: rebuild without cause.
893:
894: - Improved the testsuite to work around a problem with some utilities
895: (e.g. cp -p & touch -r) rounding sub-second timestamps.
896:
897: - Ensure that the early patches don't cause any generated-file hunks to
898: bleed-over into patches that follow.

910:
911: - None.

913: DEVELOPER RELATED:

920:
921: NEWS for rsync 3.0.1 (3 Apr 2008)
922: Protocol: 30 (unchanged)
923: Changes since 3.0.0:
924:
925: NOTABLE CHANGES IN BEHAVIOR:
926:
927: - Added the 'c'-flag to the itemizing of non-regular files so that the
928: itemized output doesn't get hidden if there were no attribute changes,
929: and also so that the itemizing of a --copy-links run will distinguish
930: between copying an identical non-regular file and the creation of a
931: revised version with a new value (e.g. a changed symlink referent, a
932: new device number, etc.).
933:
934: BUG FIXES:
935:
936: - Fixed a crash bug when a single-use rsync daemon (via remote shell) was
937: run without specifying a --config=FILE option.
938:
939: - Fixed a crash when backing up a directory that has a default ACL.
940:
941: - Fixed a bug in the handling of xattr values that could cause rsync to
942: not think that a file's extended attributes are up-to-date.
943:
944: - Fixed the working of --fake-super with --link-dest and --xattrs.
945:
946: - Fixed a hang when combining --dry-run with --remove-source-files.
947:
948: - Fixed a bug with --iconv's handling of files that cannot be converted:
949: a failed name can no longer cause a transfer failure.
950:
951: - Fixed the building of the rounding.h file on systems that need custom
952: CPPFLAGS to be used. Also improved the error reporting if the building
953: of rounding.h fails.
954:
955: - Fixed the use of the --protect-args (-s) option when talking to a daemon.
956:
957: - Fixed the --ignore-existing option's protection of files on the receiver
958: that are non-regular files on the sender (e.g. if a symlink or a dir on
959: the sender is trying to replace a file on the receiver). The reverse
960: protection (protecting a dir/symlink/device from being replaced by a
961: file) was already working.
962:
963: - Fixed an assert failure if --hard-links is combined with an option that
964: can skip a file in a set of hard-linked files (i.e. --ignore-existing,
965: --append, etc.), without skipping all the files in the set.
966:
967: - Avoid setting the modify time on a directory that already has the right
968: modify time set. This avoids tweaking the dir's ctime.
969:
970: - Improved the daemon-exclude handling to do a better job of applying the
971: exclude rules to path entries. It also sends the user an error just as
972: if the files were actually missing (instead of silently ignoring the
973: user's args), and avoids sending the user the filter-action messages
974: for these non-user-initiated rules.
975:
976: - Fixed some glitches with the dry-run code's missing-directory
977: handling, including a problem when combined with --fuzzy.
978:
979: - Fixed some glitches with the skipped-directory handling.
980:
981: - Fixed the 'T'-flag itemizing of symlinks when --time isn't preserved.
982:
983: - Fixed a glitch in the itemizing of permissions with the -E option.
984:
985: - The --append option's restricting of transfers to those that add data no
986: longer prevents the updating of non-content changes to otherwise up-to-
987: date files (i.e. those with the same content but differing permissions,
988: ownership, xattrs, etc.).
989:
990: - Don't allow --fake-super to be specified with -XX (double --xattrs)
991: because the options conflict. If a daemon has "fake super" enabled,
992: it automatically downgrades a -XX request to -X.
993:
994: - Fixed a couple bugs in the parsing of daemon-config excludes that could
995: make a floating exclude rule get treated as matching an absolute path.
996:
997: - A daemon doesn't try to auto-refuse the "iconv" option if iconv-support
998: wasn't compiled in to the daemon (avoiding a warning in the logs).
999:
1000: - Fixed the inclusion of per-dir merge files from implied dirs.
1001:
1002: - Fixed the support/rrsync script to work with the latest options that
1003: rsync sends (including its flag-specifying use of -e to the server).
1004:
1005: ENHANCEMENTS:
1006:
1007: - Added the --old-dirs (--old-d) option to make it easier for a user to
1008: ask for file-listings with older rsync versions (this is easier than
1009: having to type "-r --exclude='/*/*'" manually).
1010:
1011: - When getting an error while asking an older rsync daemon for a file
1012: listing, rsync will try to notice if the error is a rejection of the
1013: --dirs (-d) option and let the user know how to work around the issue.
1014:
1015: - Added a few more --no-OPTION overrides.
1016:
1017: - Improved the documentation of the --append option.
1018:
1019: - Improved the documentation of the filter/exclude/include daemon
1020: parameters.
1021:
1022: INTERNAL:
1023:
1024: - Fixed a couple minor bugs in the included popt library (ones which I
1025: sent to the official popt project for inclusion in the 1.14 release).
1026:
1027: - Fixed a stat() call that should have been do_stat() so that the proper
1028: normal/64-bit stat() function gets called. (Was in an area that should
1029: not have caused problems, though.)
1030:
1031: - Changed the file-glob code to do a directory scan without using the
1032: "glob" and "glob.h". This lets us do the globbing with less memory
1033: churn, and also avoid adding daemon-excluded items to the returned
1034: args.
1035:
1036: DEVELOPER RELATED:
1037:
1038: - The configure script tries to get the user's compiler to not warn about
1039: unused function parameters if the build is not including one or more of
1040: the ACL/xattrs/iconv features.
1041:
1042: - The configure script now has better checks for figuring out if the
1043: included popt code should be used or not.
1044:
1045: - Fixed two testsuite glitches: avoid a failure if someone's "cd" command
1046: outputs the current directory when cd-ing to a relative path, and made
1047: the itemized test query how rsync was built to determine if it should
1048: expect hard-linked symlinks or not.
1049:
1050: - Updated the testsuite to verify that various bug fixes remain fixed.
1051:
1052: - The RPM spec file was updated to have: (1) comments for how to use the
1053: rsync-patch tar file, and (2) an /etc/xinetd.d/rsync file.
1054:
1055: - Updated the build scripts to work with a revised FTP directory
1056: structure.

1059: NEWS for rsync 3.0.0 (1 Mar 2008)
1060: Protocol: 30 (changed)
1061: Changes since 2.6.9:
1062:
1063: NOTABLE CHANGES IN BEHAVIOR:
1064:
1065: - The handling of implied directories when using --relative has changed to
1066: send them as directories (e.g. no implied dir is ever sent as a symlink).
1067: This avoids unexpected behavior and should not adversely affect most
1068: people. If you're one of those rare individuals who relied upon having
1069: an implied dir be duplicated as a symlink, you should specify the
1070: transfer of the symlink and the transfer of the referent directory as
1071: separate args. (See also --keep-dirlinks and --no-implied-dirs.)
1072: Also, exclude rules no longer have a partial effect on implied dirs.
1073:
1074: - Requesting a remote file-listing without specifying -r (--recursive) now
1075: sends the -d (--dirs) option to the remote rsync rather than sending -r
1076: along with an extra exclude of /*/*. If the remote rsync does not
1077: understand the -d option (i.e. it is 2.6.3 or older), you will need to
1078: either turn off -d (--no-d), or specify -r --exclude='/*/*' manually.
1079:
1080: - In --dry-run mode, the last line of the verbose summary text is output
1081: with a "(DRY RUN)" suffix to help remind you that no updates were made.
1082: Similarly, --only-write-batch outputs "(BATCH ONLY)".
1083:
1084: - A writable rsync daemon with "use chroot" disabled now defaults to a
1085: symlink-munging behavior designed to make symlinks safer while also
1086: allowing absolute symlinks to be stored and retrieved. This also has
1087: the effect of making symlinks unusable while they're in the daemon's
1088: hierarchy. See the daemon's "munge symlinks" parameter for details.
1089:
1090: - Starting up an extra copy of an rsync daemon will not clobber the pidfile
1091: for the running daemon -- if the pidfile exists, the new daemon will exit
1092: with an error. This means that your wrapper script that starts the rsync
1093: daemon should be made to handle lock-breaking (if you want any automatic
1094: breaking of locks to be done).
1095:
1096: BUG FIXES:
1097:
1098: - A daemon with "use chroot = no" and excluded items listed in the daemon
1099: config file now properly checks an absolute-path arg specified for these
1100: options: --compare-dest, --link-dest, --copy-dest, --partial-dir,
1101: --backup-dir, --temp-dir, and --files-from.
1102:
1103: - A daemon can now be told to disable all user- and group-name translation
1104: on a per-module basis. This avoids a potential problem with a writable
1105: daemon module that has "use chroot" enabled -- if precautions weren't
1106: taken, a user could try to add a missing library and get rsync to use
1107: it. This makes rsync safer by default, and more configurable when id-
1108: translation is not desired. See the daemon's "numeric ids" parameter
1109: for full details.
1110:
1111: - A chroot daemon can now indicate which part of its path should affect the
1112: chroot call, and which part should become an inside-chroot path for the
1113: module. This allows you to have outside-the-transfer paths (such as for
1114: libraries) even when you enable chroot protection. The idiom used in the
1115: rsyncd.conf file is: path = /chroot/dirs/./dirs/inside
1116:
1117: - If a file's data arrived successfully on the receiving side but the
1118: rename of the temporary file to the destination file failed AND the
1119: --remove-source-files (or the deprecated --remove-sent-files) option
1120: was specified, rsync no longer erroneously removes the associated
1121: source file.
1122:
1123: - Fixed the output of -ii when combined with one of the --*-dest options:
1124: it now itemizes all the items, not just the changed ones.
1125:
1126: - Made the output of all file types consistent when using a --*-dest
1127: option. Prior versions would output too many creation events for
1128: matching items.
1129:
1130: - The code that waits for a child pid now handles being interrupted by a
1131: signal. This fixes a problem with the pre-xfer exec function not being
1132: able to get the exit status from the script.
1133:
1134: - A negated filter rule (i.e. with a '!' modifier) no longer loses the
1135: negation when sending the filter rules to the remote rsync.
1136:
1137: - Fixed a problem with the --out-format (aka --log-format) option %f: it
1138: no longer outputs superfluous directory info for a non-daemon rsync.
1139:
1140: - Fixed a problem with -vv (double --verbose) and --stats when "pushing"
1141: files (which includes local copies). Version 2.6.9 would complete the
1142: copy, but exit with an error when the receiver output its memory stats.
1143:
1144: - If --password-file is used on a non-daemon transfer, rsync now complains
1145: and exits. This should help users figure out that they can't use this
1146: option to control a remote shell's password prompt.
1147:
1148: - Make sure that directory permissions of a newly-created destination
1149: directory are handled right when --perms is left off.
1150:
1151: - The itemized output of a newly-created destination directory is now
1152: output as a creation event, not a change event.
1153:
1154: - Improved --hard-link so that more corner cases are handled correctly
1155: when combined with options such as --link-dest and/or --ignore-existing.
1156:
1157: - The --append option no longer updates a file that has the same size.
1158:
1159: - Fixed a bug when combining --backup and --backup-dir with --inplace:
1160: any missing backup directories are now created.
1161:
1162: - Fixed a bug when using --backup and --inplace with --whole-file or
1163: --read-batch: backup files are actually created now.
1164:
1165: - The daemon pidfile is checked and created sooner in the startup sequence.
1166:
1167: - If a daemon module's "path" value is not an absolute pathname, the code
1168: now makes it absolute internally (making it work properly).
1169:
1170: - Ensure that a temporary file always has owner-write permission while we
1171: are writing to it. This avoids problems with some network filesystems
1172: when transfering read-only files.
1173:
1174: - Any errors output about password-file reading no longer cause an error at
1175: the end of the run about a partial transfer.
1176:
1177: - The --read-batch option for protocol 30 now ensures that several more
1178: options are set correctly for the current batch file: --iconv, --acls,
1179: --xattrs, --inplace, --append, and --append-verify.
1180:
1181: - Using --only-write-batch to a daemon receiver now works properly (older
1182: versions would update some files while writing the batch).
1183:
1184: - Avoid outputting a "file has vanished" message when the file is a broken
1185: symlink and --copy-unsafe-links or --copy-dirlinks is used (the code
1186: already handled this for --copy-links).
1187:
1188: - Fixed the combination of --only-write-batch and --dry-run.
1189:
1190: - Fixed rsync's ability to remove files that are not writable by the file's
1191: owner when rsync is running as the same user.
1192:
1193: - When transferring large files, the sender's hashtable of checksums is
1194: kept at a more reasonable state of fullness (no more than 80% full) so
1195: that the scanning of the hashtable will not bog down as the number of
1196: blocks increases.
1197:
1198: ENHANCEMENTS:
1199:
1200: - A new incremental-recursion algorithm is now used when rsync is talking
1201: to another 3.x version. This starts the transfer going more quickly
1202: (before all the files have been found), and requires much less memory.
1203: See the --recursive option in the manpage for some restrictions.
1204:
1205: - Lowered memory use in the non-incremental-recursion algorithm for typical
1206: option values (usually saving from 21-29 bytes per file).
1207:
1208: - The default --delete algorithm is now --delete-during when talking to a
1209: 3.x rsync. This is a faster scan than using --delete-before (which is
1210: the default when talking to older rsync versions), and is compatible with
1211: the new incremental recursion mode.
1212:
1213: - Rsync now allows multiple remote-source args to be specified rather than
1214: having to rely on a special space-splitting side-effect of the remote-
1215: shell. Additional remote args must specify the same host or an empty one
1216: (e.g. empty: :file1 or ::module/file2). For example, this means that
1217: local use of brace expansion now works: rsync -av host:dir/{f1,f2} .
1218:
1219: - Added the --protect-args (-s) option, that tells rsync to send most of
1220: the command-line args at the start of the transfer rather than as args
1221: to the remote-shell command. This protects them from space-splitting,
1222: and only interprets basic wildcard special shell characters (*?[).
1223:
1224: - Added the --delete-delay option, which is a more efficient way to delete
1225: files at the end of the transfer without needing a separate delete pass.
1226:
1227: - Added the --acls (-A) option to preserve Access Control Lists. This is
1228: an improved version of the prior patch that was available, and it even
1229: supports OS X ACLs. If you need to have backward compatibility with old,
1230: ACL-patched versions of rsync, apply the acls.diff file from the patches
1231: dir.
1232:
1233: - Added the --xattrs (-X) option to preserve extended attributes. This is
1234: an improved version of the prior patch that was available, and it even
1235: supports OS X xattrs (which includes their resource fork data). If you
1236: need to have backward compatibility with old, xattr-patched versions of
1237: rsync, apply the xattrs.diff file from the patches dir.
1238:
1239: - Added the --fake-super option that allows a non-super user to preserve
1240: all attributes of a file by using a special extended-attribute idiom.
1241: It even supports the storing of foreign ACL data on your backup server.
1242: There is also an analogous "fake super" parameter for an rsync daemon.
1243:
1244: - Added the --iconv option, which allows rsync to convert filenames from
1245: one character-set to another during the transfer. The default is to
1246: make this feature available as long as your system has iconv_open().
1247: If compilation fails, specify --disable-iconv to configure, and then
1248: rebuild. If you want rsync to perform character-set conversions by
1249: default, you can specify --enable-iconv=CONVERT_STRING with the default
1250: value for the --iconv option that you wish to use. For example,
1251: "--enable-iconv=." is a good choice. See the rsync manpage for an
1252: explanation of the --iconv option's settings.
1253:
1254: - A new daemon config parameter, "charset", lets you control the character-
1255: set that is used during an --iconv transfer to/from a daemon module. You
1256: can also set your daemon to refuse "no-iconv" if you want to force the
1257: client to use an --iconv transfer (requiring an rsync 3.x client).
1258:
1259: - Added the --skip-compress=LIST option to override the default list of
1260: file suffixes that will not be compressed when using --compress (-z).
1261:
1262: - The daemon's default for "dont compress" was extended to include:
1263: *.7z *.mp[34] *.mov *.avi *.ogg *.jpg *.jpeg
1264: The name-matching routine was also optimized to run more quickly.
1265:
1266: - The --max-delete option now outputs a warning if it skipped any file
1267: deletions, including a count of how many deletions were skipped. (Older
1268: versions just silently stopped deleting things.)
1269:
1270: - You may specify --max-delete=0 to a 3.0.0 client to request that it warn
1271: about extraneous files without deleting anything. If you're not sure
1272: what version the client is, you can use the less-obvious --max-delete=-1,
1273: as both old and new versions will treat that as the same request (though
1274: older versions don't warn).
1275:
1276: - The --hard-link option now uses less memory on both the sending and
1277: receiving side for all protocol versions. For protocol 30, the use of a
1278: hashtable on the sending side allows us to more efficiently convey to the
1279: receiver what files are linked together. This reduces the amount of data
1280: sent over the socket by a considerable margin (rather than adding more
1281: data), and limits the in-memory storage of the device+inode information
1282: to just the sending side for the new protocol 30, or to the receiving
1283: side when speaking an older protocol (note that older rsync versions kept
1284: the device+inode information on both sides).
1285:
1286: - The filter rules now support a perishable ("p") modifier that marks rules
1287: that should not have an effect in a directory that is being deleted. e.g.
1288: -f '-p .svn/' would only affect "live" .svn directories.
1289:
1290: - Rsync checks all the alternate-destination args for validity (e.g.
1291: --link-dest). This lets the user know when they specified a directory
1292: that does not exist.
1293:
1294: - If we get an ENOSYS error setting the time on a symlink, we don't
1295: complain about it anymore (for those systems that even support the
1296: setting of the modify-time on a symlink).
1297:
1298: - Protocol 30 now uses MD5 checksums instead of MD4.
1299:
1300: - Changed the --append option to not checksum the existing data in the
1301: destination file, which speeds up file appending.
1302:
1303: - Added the --append-verify option, which works like the older --append
1304: option (verifying the existing data in the destination file). For
1305: compatibility with older rsync versions, any use of --append that is
1306: talking protocol 29 or older will revert to the --append-verify method.
1307:
1308: - Added the --contimeout=SECONDS option that lets the user specify a
1309: connection timeout for rsync daemon access.
1310:
1311: - Documented and extended the support for the RSYNC_CONNECT_PROG variable
1312: that can be used to enhance the client side of a daemon connection.
1313:
1314: - Improved the dashes and double-quotes in the nroff manpage output.
1315:
1316: - Rsync now supports a lot more --no-OPTION override options.
1317:
1318: INTERNAL:
1319:
1320: - The file-list sorting algorithm now uses a sort that keeps any same-
1321: named items in the same order as they were specified. This allows
1322: rsync to always ensure that the first of the duplicates is the one
1323: that will be included in the copy. The new sort is also faster
1324: than the glibc version of qsort() and mergesort().
1325:
1326: - Rsync now supports the transfer of 64-bit timestamps (time_t values).
1327:
1328: - Made the file-deletion code use a little less stack when recursing
1329: through a directory hierarchy of extraneous files.
1330:
1331: - Fixed a build problem with older (2.x) versions of gcc.
1332:
1333: - Added some isType() functions that make dealing with signed characters
1334: easier without forcing variables via casts.
1335:
1336: - Changed strcat/strcpy/sprintf function calls to use safer versions.
1337:
1338: - Upgraded the included popt version to 1.10.2 and improved its use of
1339: string-handling functions.
1340:
1341: - Added missing prototypes for compatibility functions from the lib dir.
1342:
1343: - Configure determines if iconv() has a const arg, allowing us to avoid a
1344: compiler warning.
1345:
1346: - Made the sending of some numbers more efficient for protocol 30.
1347:
1348: - Make sure that a daemon process doesn't mind if the client was weird and
1349: omitted the --server option.
1350:
1351: - There are more internal logging categories available in protocol 30 than
1352: the age-old FINFO and FERROR, including FERROR_XFER and FWARN. These new
1353: categories allow some errors and warnings to go to stderr without causing
1354: an erroneous end-of-run warning about some files not being able to be
1355: transferred.
1356:
1357: - Improved the use of "const" on pointers.
1358:
1359: - Improved J.W.'s pool_alloc routines to add a way of incrementally freeing
1360: older sections of a pool's memory.
1361:
1362: - The getaddrinfo.c compatibility code in the "lib" dir was replaced with
1363: some new code (derived from samba, derived from PostgreSQL) that has a
1364: better license than the old code.
1365:
1366: DEVELOPER RELATED:
1367:
1368: - Rsync is now licensed under the GPLv3 or later.
1369:
1370: - Rsync is now being maintained in a "git" repository instead of CVS
1371: (though the old CVS repository still exists for historical access).
1372: Several maintenance scripts were updated to work with git.
1373:
1374: - Generated files are no longer committed into the source repository. The
1375: autoconf and autoheader commands are now automatically run during the
1376: normal use of "configure" and "make". The latest dev versions of all
1377: generated files can also be copied from the samba.org web site (see the
1378: prepare-source script's fetch option).
1379:
1380: - The "patches" directory of diff files is now built from branches in the
1381: rsync git repository (branch patch/FOO creates file patches/FOO.diff).
1382: This directory is now distributed in a separate separate tar file named
1383: rsync-patches-VERSION.tar.gz instead of the main rsync-VERSION.tar.gz.
1384:
1385: - The proto.h file is now built using a simple perl script rather than a
1386: complex awk script, which proved to be more widely compatible.
1387:
1388: - When running the tests, we now put our per-test temp dirs into a sub-
1389: directory named testtmp (which is created, if missing). This allows
1390: someone to symlink the testtmp directory to another filesystem (which is
1391: useful if the build dir's filesystem does not support ACLs and xattrs,
1392: but another filesystem does).
1393:
1394: - Rsync now has a way of handling protocol-version changes during the
1395: development of a new protocol version. This causes any out-of-sync
1396: versions to speak an older protocol rather than fail in a cryptic manner.
1397: This addition makes it safer to deploy a pre-release version that may
1398: interact with the public. This new exchange of sub-version info does not
1399: interfere with the {MIN,MAX}_PROTOCOL_VERSION checking algorithm (which
1400: does not have enough range to allow the main protocol number to be
1401: incremented for every minor tweak in that happens during development).
1402:
1403: - The csprotocol.txt file was updated to mention the daemon protocol change
1404: in the 3.0.0 release.
1405:
1406:
1407: NEWS for rsync 2.6.9 (6 Nov 2006)
1408: Protocol: 29 (unchanged)
1409: Changes since 2.6.8:
1410:
1411: BUG FIXES:
1412:
1413: - If rsync is interrupted via a handled signal (such as SIGINT), it will
1414: once again clean-up its temp file from the destination dir.
1415:
1416: - Fixed an overzealous sanitizing bug in the handling of the --link-dest,
1417: --copy-dest, and --compare-dest options to a daemon without chroot: if
1418: the copy's destination dir is deeper than the top of the module's path,
1419: these options now accept a safe number of parent-dir (../) references
1420: (since these options are relative to the destination dir). The old code
1421: incorrectly chopped off all "../" prefixes for these options, no matter
1422: how deep the destination directory was in the module's hierarchy.
1423:
1424: - Fixed a bug where a deferred info/error/log message could get sent
1425: directly to the sender instead of being handled by rwrite() in the
1426: generator. This fixes an "unexpected tag 3" fatal error, and should
1427: also fix a potential problem where a deferred info/error message from
1428: the receiver might bypass the log file and get sent only to the client
1429: process. (These problems could only affect an rsync daemon that was
1430: receiving files.)
1431:
1432: - Fixed a bug when --inplace was combined with a --*-dest option and we
1433: update a file's data using an alternate basis file. The code now
1434: notices that it needs to copy the matching data from the basis file
1435: instead of (wrongly) assuming that it was already present in the file.
1436:
1437: - Fixed a bug where using --dry-run with a --*-dest option with a path
1438: relative to a directory that does not yet exist: the affected option
1439: gets its proper path value so that the output of the dry-run is right.
1440:
1441: - Fixed a bug in the %f logfile escape when receiving files: the
1442: destination path is now included in the output (e.g. you can now tell
1443: when a user specifies a subdir inside a module).
1444:
1445: - If the receiving side fails to create a directory, it will now skip
1446: trying to update everything that is inside that directory.
1447:
1448: - If --link-dest is specified with --checksum but without --times, rsync
1449: will now allow a hard-link to be created to a matching link-dest file
1450: even when the file's modify-time doesn't match the server's file.
1451:
1452: - The daemon now calls more timezone-using functions prior to doing a
1453: chroot. This should help some C libraries to generate proper timestamps
1454: from inside a chrooted daemon (and to not try to access /etc/timezone
1455: over and over again).
1456:
1457: - Fixed a bug in the handling of an absolute --partial-dir=ABS_PATH option:
1458: it now deletes an alternate basis file from the partial-dir that was used
1459: to successfully update a destination file.
1460:
1461: - Fixed a bug in the handling of --delete-excluded when using a per-dir
1462: merge file: the merge file is now honored on the receiving side, and
1463: only its unqualified include/exclude commands are ignored (just as is
1464: done for global include/excludes).
1465:
1466: - Fixed a recent bug where --delete was not working when transferring from
1467: the root (/) of the filesystem with --relative enabled.
1468:
1469: - Fixed a recent bug where an --exclude='*' could affect the root (/) of
1470: the filesystem with --relative enabled.
1471:
1472: - When --inplace creates a file, it is now created with owner read/write
1473: permissions (0600) instead of no permissions at all. This avoids a
1474: problem continuing a transfer that was interrupted (since --inplace
1475: will not update a file that has no write permissions).
1476:
1477: - If either --remove-source-files or --remove-sent-files is enabled and we
1478: are unable to remove the source file, rsync now outputs an error.
1479:
1480: - Fixed a bug in the daemon's "incoming chmod" rule: newly-created
1481: directories no longer get the 'F' (file) rules applied to them.
1482:
1483: - Fixed an infinite loop bug when a filter rule was rejected due to being
1484: overly long.
1485:
1486: - When the server receives a --partial-dir option from the client, it no
1487: longer runs the client-side code that adds an assumed filter rule (since
1488: the client will be sending us the rules in the usual manner, and they
1489: may have chosen to override the auto-added rule).
1490:
1491: ENHANCEMENTS:
1492:
1493: - Added the --log-file=FILE and --log-file-format=FORMAT options. These
1494: can be used to tell any rsync to output what it is doing to a log file.
1495: They work with a client rsync, a non-daemon server rsync (see the man
1496: page for instructions), and also allows the overriding of rsyncd.conf
1497: settings when starting a daemon.
1498:
1499: - The --log-format option was renamed to be --out-format to avoid confusing
1500: it with affecting the log-file output. (The old option remains as an
1501: alias for the new to preserve backward compatibility.)
1502:
1503: - Made "log file" and "syslog facility" settable on a per-module basis in
1504: the daemon's config file.
1505:
1506: - Added the --remove-source-files option as a replacement for the (now
1507: deprecated) --remove-sent-files option. This new option removes all
1508: non-dirs from the source directories, even if the file was already
1509: up-to-date. This fixes a problem where interrupting an rsync that
1510: was using --remove-sent-files and restarting it could leave behind
1511: a file that the earlier rsync synchronized, but didn't get to remove.
1512: (The deprecated --remove-sent-files is still understood for now, and
1513: still behaves in the same way as before.)
1514:
1515: - Added the option --no-motd to suppress the message-of-the-day output
1516: from a daemon when doing a copy. (See the manpage for a caveat.)
1517:
1518: - Added a new environment variable to the pre-/post-xfer exec commands (in
1519: the daemon's config file): RSYNC_PID. This value will be the same in
1520: both the pre- and post-xfer commands, so it can be used as a unique ID
1521: if the pre-xfer command wants to cache some arg/request info for the
1522: post-xfer command.
1523:
1524: INTERNAL:
1525:
1526: - Did a code audit using IBM's code-checker program and made several
1527: changes, including: replacing most of the strcpy() and sprintf()
1528: calls with strlcpy(), snprintf(), and memcpy(), adding a 0-value to
1529: an enum that had been intermingling a literal 0 with the defined enum
1530: values, silencing some uninitialized memory checks, marking some
1531: functions with a "noreturn" attribute, and changing an "if" that
1532: could never succeed on some platforms into a pre-processor directive
1533: that conditionally compiles the code.
1534:
1535: - Fixed a potential bug in f_name_cmp() when both the args are a
1536: top-level "." dir (which doesn't happen in normal operations).
1537:
1538: - Changed exit_cleanup() so that it can never return instead of exit.
1539: The old code might return if it found the exit_cleanup() function
1540: was being called recursively. The new code is segmented so that
1541: any recursive calls move on to the next step of the exit-processing.
1542:
1543: - The macro WIFEXITED(stat) will now be defined if the OS didn't already
1544: define it.
1545:
1546: DEVELOPER RELATED:
1547:
1548: - The acls.diff and xattrs.diff patches have received a bunch of work to
1549: make them much closer to being acceptable in the main distribution.
1550: The xattrs patch also has some preliminary Mac OS X and FreeBSD
1551: compatibility code that various system types to exchange extended
1552: file-attributes.
1553:
1554: - A new diff in the patches dir, fake-root.diff, allows rsync to
1555: maintain a backup hierarchy with full owner, group, and device info
1556: without actually running as root. It does this using a special
1557: extended attribute, so it depends on xattrs.diff (which depends on
1558: acls.diff).
1559:
1560: - The rsync.yo and rsyncd.conf.yo files have been updated to work
1561: better with the latest yodl 2.x releases.
1562:
1563: - Updated config.guess and config.sub to their 2006-07-02 versions.
1564:
1565: - Updated various files to include the latest FSF address and to have
1566: consistent opening comments.

1569: NEWS for rsync 2.6.8 (22 Apr 2006)
1570: Protocol: 29 (unchanged)
1571: Changes since 2.6.7:
1572:
1573: BUG FIXES:
1574:
1575: - Fixed a bug in the exclude code where an anchored exclude without any
1576: wildcards fails to match an absolute source arg, but only when --relative
1577: is in effect.
1578:
1579: - Improved the I/O code for the generator to fix a potential hang when the
1580: receiver gets an EOF on the socket but the generator's select() call
1581: never indicates that the socket is writable for it to be notified about
1582: the EOF. (This can happen when using stunnel).
1583:
1584: - Fixed a problem with the file-reading code where a failed read (such as
1585: that caused by a bad sector) would not advance the file's read-position
1586: beyond the failed read's data.
1587:
1588: - Fixed a logging bug where the "log file" directive was not being honored
1589: in a single-use daemon (one spawned by a remote-shell connection or by
1590: init).
1591:
1592: - If rsync cannot honor the --delete option, we output an error and exit
1593: instead of silently ignoring the option.
1594:
1595: - Fixed a bug in the --link-dest code that prevented special files (such as
1596: fifos) from being linked.
1597:
1598: - The ability to hard-link symlinks and special files is now determined at
1599: configure time instead of at runtime. This fixes a bug with --link-dest
1600: creating a hard-link to a symlink's referent on a BSD system.
1601:
1602: ENHANCEMENTS:
1603:
1604: - In daemon mode, if rsync fails to bind to the requested port, the
1605: error(s) returned by socket() and/or bind() are now logged.
1606:
1607: - When we output a fatal error, we now output the version of rsync in the
1608: message.
1609:
1610: - Improved the documentation for the --owner and --group options.
1611:
1612: - The rsyncstats script in "support" has an improved line-parsing regex
1613: that is easier to read and also makes it to parse syslog-generated lines.
1614:
1615: - A new script in "support": file-attr-restore, can be used to restore the
1616: attributes of a file-set (the permissions, ownership, and group info)
1617: taken from the cached output of a "find ARG... -ls" command.
1618:
1619: DEVELOPER RELATED:
1620:
1621: - Removed the unused function write_int_named(), the unused variable
1622: io_read_phase, and the rarely used variable io_write_phase. This also
1623: elides the confusing 'phase "unknown"' part of one error message.
1624:
1625: - Removed two unused configure checks and two related (also unused)
1626: compatibility functions.
1627:
1628: - The xattrs.diff patch received a security fix that prevents a potential
1629: buffer overflow in the receive_xattr() code.
1630:
1631: - The acls.diff patch has been improved quite a bit, with more to come.
1632:
1633: - A new patch was added: log-file.diff. This contains an early version of
1634: a future option, --log-file=FILE, that will allow any rsync to log its
1635: actions to a file (something that only a daemon supports at present).
1636:
1637:
1638: NEWS for rsync 2.6.7 (11 Mar 2006)
1639: Protocol: 29 (unchanged)
1640: Changes since 2.6.6:
1641:
1642: OUTPUT CHANGES:
1643:
1644: - The letter 'D' in the itemized output was being used for both devices
1645: (character or block) as well as other special files (such as fifos and
1646: named sockets). This has changed to separate non-device special files
1647: under the 'S' designation (e.g. "cS+++++++ path/fifo"). See also the
1648: "--specials" option, below.
1649:
1650: - The way rsync escapes unreadable characters has changed. First, rsync
1651: now has support for recognizing valid multibyte character sequences in
1652: your current locale, allowing it to escape fewer characters than before
1653: for a locale such as UTF-8. Second, it now uses an escape idiom of
1654: "\#123", which is the literal string "\#" followed by exactly 3 octal
1655: digits. Rsync no longer doubles a backslash character in a filename
1656: (e.g. it used to output "foo\\bar" when copying "foo\bar") -- now it only
1657: escapes a backslash that is followed by a hash-sign and 3 digits (0-9)
1658: (e.g. it will output "foo\#134#789" when copying "foo\#789"). See also
1659: the --8-bit-output (-8) option, mentioned below.
1660:
1661: Script writers: the local rsync is the one that outputs escaped names,
1662: so if you need to support unescaping of filenames for older rsyncs, I'd
1663: suggest that you parse the output of "rsync --version" and only use the
1664: old unescaping rules for 2.6.5 and 2.6.6.
1665:
1666: BUG FIXES:
1667:
1668: - Fixed a really old bug that caused --checksum (-c) to checksum all the
1669: files encountered during the delete scan (ouch).
1670:
1671: - Fixed a potential hang in a remote generator: when the receiver gets a
1672: read-error on the socket, it now signals the generator about this so that
1673: the generator does not try to send any of the terminating error messages
1674: to the client (avoiding a potential hang in some setups).
1675:
1676: - Made hard-links work with symlinks and devices again.
1677:
1678: - If the sender gets an early EOF reading a source file, we propagate this
1679: error to the receiver so that it can discard the file and try requesting
1680: it again (which is the existing behavior for other kinds of read errors).
1681:
1682: - If a device-file/special-file changes permissions, rsync now updates the
1683: permissions without recreating the file.
1684:
1685: - If the user specifies a remote-host for both the source and destination,
1686: we now output a syntax error rather than trying to open the destination
1687: hostspec as a filename.
1688:
1689: - When --inplace creates a new destination file, rsync now creates it with
1690: permissions 0600 instead of 0000 -- this makes restarting possible when
1691: the transfer gets interrupted in the middle of sending a new file.
1692:
1693: - Reject the combination of --inplace and --sparse since the sparse-output
1694: algorithm doesn't work when overwriting existing data.
1695:
1696: - Fixed the directory name in the error that is output when pop_dir()
1697: fails.
1698:
1699: - Really fixed the parsing of a "!" entry in .cvsignore files this time.
1700:
1701: - If the generator gets a stat() error on a file, output it (this used to
1702: require at least -vv for the error to be seen).
1703:
1704: - If waitpid() fails or the child rsync didn't exit cleanly, we now handle
1705: the exit status properly and generate a better error.
1706:
1707: - Fixed some glitches in the double-verbose output when using --copy-dest,
1708: --link-dest, or --compare-dest. Also improved how the verbose output
1709: handles hard-links (within the transfer) that had an up-to-date alternate
1710: "dest" file, and copied files (via --copy-dest).
1711:
1712: - Fixed the matching of the dont-compress items (e.g. *.gz) against files
1713: that have a path component containing a slash.
1714:
1715: - If the code reading a filter/exclude file gets an EINTR error, rsync now
1716: clears the error flag on the file handle so it can keep on reading.
1717:
1718: - If --relative is active, the sending side cleans up trailing "/" or "/."
1719: suffixes to avoid triggering a bug in older rsync versions. Also, we now
1720: reject a ".." dir if it would be sent as a relative dir.
1721:
1722: - If a non-directory is in the way of a directory and rsync is run with
1723: --dry-run and --delete, rsync no longer complains about not being able
1724: to opendir() the not-yet present directory.
1725:
1726: - When --list-only is used and a non-existent local destination dir was
1727: also specified as a destination, rsync no longer generates a warning
1728: about being unable to create the missing directory.
1729:
1730: - Fixed some problems with --relative --no-implied-dirs when the
1731: destination directory did not yet exist: we can now create a symlink or
1732: device when it is the first thing in the missing dir, and --fuzzy no
1733: longer complains about being unable to open the missing dir.
1734:
1735: - Fixed a bug where the --copy-links option would not affect implied
1736: directories without --copy-unsafe-links (see --relative).
1737:
1738: - Got rid of the need for --force to be used in some circumstances with
1739: --delete-after (making it consistent with --delete-before/-during).
1740:
1741: - Rsync now ignores the SIGXFSZ signal, just in case your OS sends this
1742: when a file is too large (rsync handles the write error).
1743:
1744: - Fixed a bug in the Proxy-Authorization header's base64-encoded value: it
1745: was not properly padded with trailing '=' chars. This only affects a
1746: user that need to use a password-authenticated proxy for an outgoing
1747: daemon-rsync connection.
1748:
1749: - If we're transferring an empty directory to a new name, rsync no longer
1750: forces S_IWUSR if it wasn't already set, nor does it accidentally leave
1751: it set.
1752:
1753: - Fixed a bug in the debug output (-vvvvv) that could mention the wrong
1754: checksum for the current file offset.
1755:
1756: - Rsync no longer allows a single directory to be copied over a non-
1757: directory destination arg.
1758:
1759: ENHANCEMENTS:
1760:
1761: - Added the --append option that makes rsync append data onto files that
1762: are longer on the source than the destination (this includes new files).
1763:
1764: - Added the --min-size=SIZE option to exclude small files from the
1765: transfer.
1766:
1767: - Added the --compress-level option to allow you to set how aggressive
1768: rsync's compression should be (this option implies --compress).
1769:
1770: - Enhanced the parsing of the SIZE value for --min-size and --max-size to
1771: allow easy entry of multiples of 1000 (instead of just multiples of 1024)
1772: and off-by-one values too (e.g. --max-size=8mb-1).
1773:
1774: - Added the --8-bit-output (-8) option, which tells rsync to avoid escaping
1775: high-bit characters that it thinks are unreadable in the current locale.
1776:
1777: - The new option --human-readable (-h) changes the output of --progress,
1778: --stats, and the end-of-run summary to be easier to read. If repeated,
1779: the units become powers of 1024 instead of powers of 1000. (The old
1780: meaning of -h, as a shorthand for --help, still works as long as you
1781: just use it on its own, as in "rsync -h".)
1782:
1783: - If lutimes() and/or lchmod() are around, use them to allow the
1784: preservation of attributes on symlinks.
1785:
1786: - The --link-dest option now affects symlinks and devices (when possible).
1787:
1788: - Added two config items to the rsyncd.conf parsing: "pre-xfer exec" and
1789: "post-xfer exec". These allow a command to be specified on a per-module
1790: basis that will be run before and/or after a daemon-mode transfer. (See
1791: the man page for a list of the environment variables that are set with
1792: information about the transfer.)
1793:
1794: - When using the --relative option, you can now insert a dot dir in
1795: the source path to indicate where the replication of the source dirs
1796: should start. For example, if you specify a source path of
1797: rsync://host/module/foo/bar/./baz/dir with -R, rsync will now only
1798: replicate the "baz/dir" part of the source path (note: a trailing
1799: dot dir is unaffected unless it also has a trailing slash).
1800:
1801: - Added some new --no-FOO options that make it easier to override unwanted
1802: implied or default options. For example, "-a --no-o" (aka "--archive
1803: --no-owner") can be used to turn off the preservation of file ownership
1804: that is implied by -a.
1805:
1806: - Added the --chmod=MODE option that allows the destination permissions to
1807: be changed from the source permissions. E.g. --chmod=g+w,o-rwx
1808:
1809: - Added the "incoming chmod" and "outgoing chmod" daemon options that allow
1810: a module to specify what permissions changes should be applied to all
1811: files copied to and from the daemon.
1812:
1813: - Allow the --temp-dir option to be specified when starting a daemon, which
1814: sets the default temporary directory for incoming files.
1815:
1816: - If --delete is combined with --dirs without --recursive, rsync will now
1817: delete in any directory whose content is being synchronized.
1818:
1819: - If --backup is combined with --delete without --backup-dir (and without
1820: --delete-excluded), we add a "protect" filter-rule to ensure that files
1821: with the backup suffix are not deleted.
1822:
1823: - The file-count stats that are output by --progress were improved to
1824: better indicate what the numbers mean. For instance, the output:
1825: "(xfer#5, to-check=8383/9999)" indicates that this was the fifth file
1826: to be transferred, and we still need to check 8383 more files out of
1827: a total of 9999.
1828:
1829: - The include/exclude code now allows a dir/*** directive (with 3 trailing
1830: stars) to match both the dir itself as well as all the content below the
1831: dir (dir/** would not match the dir).
1832:
1833: - Added the --prune-empty-dirs (-m) option that makes the receiving rsync
1834: discard empty chains of directories from the file-list. This makes it
1835: easier to selectively copy files from a source hierarchy and end up with
1836: just the directories needed to hold the resulting files.
1837:
1838: - If the --itemize-changes (-i) option is repeated, rsync now includes
1839: unchanged files in the itemized output (similar to -vv, but without all
1840: the other verbose messages that can get in the way). Of course, the
1841: client must be version 2.6.7 for this to work, but the remote rsync only
1842: needs to be 2.6.7 if you're pushing files.
1843:
1844: - Added the --specials option to tell rsync to copy non-device special
1845: files (which rsync now attempts even as a normal user). The --devices
1846: option now requests the copying of just devices (character and block).
1847: The -D option still requests both (e.g. --devices and --specials), -a
1848: still implies -D, and non-root users still get a silent downgrade that
1849: omits device copying.
1850:
1851: - Added the --super option to make the receiver always attempt super-user
1852: activities. This is useful for systems that allow things such as devices
1853: to be created or ownership to be set without being UID 0, and is also
1854: useful for someone who wants to ensure that errors will be output if the
1855: receiving rsync isn't being run as root.
1856:
1857: - Added the --sockopts option for those few who want to customize the TCP
1858: options used to contact a daemon rsync.
1859:
1860: - Added a way for the --temp-dir option to be combined with a partial-dir
1861: setting that lets rsync avoid non-atomic updates (for those times when
1862: --temp-dir is not being used because space is tight).
1863:
1864: - A new support script, files-to-excludes, will transform a list of files
1865: into a set of include/exclude directives that will copy those files.
1866:
1867: - A new option, --executability (-E) can be used to preserve just the
1868: execute bit on files, for those times when using the --perms option is
1869: not desired.
1870:
1871: - The daemon now logs each connection and also each module-list request
1872: that it receives.
1873:
1874: - New log-format options: %M (modtime), %U (uid), %G (gid), and %B
1875: (permission bits, e.g. "rwxr-xrwt").
1876:
1877: - The --dry-run option no longer forces the enabling of --verbose.
1878:
1879: - The --remove-sent-files option now does a better job of incrementally
1880: removing the sent files on the sending side (older versions tended to
1881: clump up all the removals at the end).
1882:
1883: - A daemon now supersedes its minimal SIGCHLD handler with the standard
1884: PID-remembering version after forking. This ensures that the generator
1885: can get the child-exit status from the receiver.
1886:
1887: - Use of the --bwlimit option no longer interferes with the remote rsync
1888: sending error messages about invalid/refused options.
1889:
1890: - Rsync no longer returns a usage error when used with one local source arg
1891: and no destination: this now implies the --list-only option, just like
1892: the comparable situation with a remote source arg.
1893:
1894: - Added the --copy-dirlinks option, a more limited version of --copy-links.
1895:
1896: - Various documentation improvements, including: a better synopsis, some
1897: improved examples, a better discussion of the presence and absence of
1898: --perms (including how it interacts with the new --executability and
1899: --chmod options), an extended discussion of --temp-dir, an improved
1900: discussion of --partial-dir, a better description of rsync's pattern
1901: matching characters, an improved --no-implied-dirs section, and the
1902: documenting of what the --stats option outputs.
1903:
1904: - Various new and updated diffs in the patches dir, including: acls.diff,
1905: xattrs.diff, atimes.diff, detect-renamed.diff, and slp.diff.
1906:
1907: INTERNAL:
1908:
1909: - We now use sigaction() and sigprocmask() if possible, and fall back on
1910: signal() if not. Using sigprocmask() ensures that rsync enables all the
1911: signals that it needs, just in case it was started in a masked state.
1912:
1913: - Some buffer sizes were expanded a bit, particularly on systems where
1914: MAXPATHLEN is overly small (e.g. cygwin).
1915:
1916: - If io_printf() tries to format more data than fits in the buffer, exit
1917: with an error instead of transmitting a truncated buffer.
1918:
1919: - If a va_copy macro is defined, lib/snprintf.c will use it when defining
1920: the VA_COPY macro.
1921:
1922: - Reduced the amount of stack memory needed for each level of directory
1923: recursion by nearly MAXPATHLEN bytes.
1924:
1925: - The wildmatch function was extended to allow an array of strings to be
1926: supplied as the string to match. This allows the exclude code to do less
1927: string copying.
1928:
1929: - Got rid of the safe_fname() function (and all the myriad calls) and
1930: replaced it with a new function in the log.c code that filters all the
1931: output going to the terminal.
1932:
1933: - Unified the f_name() and the f_name_to() functions.
1934:
1935: - Improved the hash-table code the sender uses to handle checksums to make
1936: it use slightly less memory and run just a little faster.
1937:
1938: DEVELOPER RELATED:
1939:
1940: - The diffs in the patches dir now require "patch -p1 <DIFF" instead of
1941: the previous -p0. Also, the version included in the release tar now
1942: affect generated files (e.g. configure, rsync.1, proto.h, etc.), so
1943: it is no longer necessary to run autoconf and/or yodl unless you're
1944: applying a patch that was checked out from CVS.
1945:
1946: - Several diffs in the patches dir now use the proper --enable-FOO
1947: configure option instead of --with-FOO to turn on the inclusion of
1948: the newly patched feature.
1949:
1950: - There is a new script, "prepare-source" than can be used to update the
1951: various generated files (proto.h, configure, etc.) even before configure
1952: has created the Makefile (this is mainly useful when patching the source
1953: with a patch that doesn't affect generated files).
1954:
1955: - The testsuite now sets HOME so that it won't be affected by a file such
1956: as ~/.popt.
1957:
1958:
1959: NEWS for rsync 2.6.6 (28 Jul 2005)
1960: Protocol: 29 (unchanged)
1961: Changes since 2.6.5:
1962:
1963: SECURITY FIXES:
1964:
1965: - The zlib code was upgraded to version 1.2.3 in order to make it more
1966: secure. While the widely-publicized security problem in zlib 1.2.2 did
1967: not affect rsync, another security problem surfaced that affects rsync's
1968: zlib 1.1.4.
1969:
1970: BUG FIXES:
1971:
1972: - The setting of flist->high in clean_flist() was wrong for an empty list.
1973: This could cause flist_find() to crash in certain rare circumstances
1974: (e.g. if just the right directory setup was around when --fuzzy was
1975: combined with --link-dest).
1976:
1977: - The outputting of hard-linked files when verbosity was > 1 was not right:
1978: (1) Without -i it would output the name of each hard-linked file as
1979: though it had been changed; it now outputs a "is hard linked" message for
1980: the file. (2) With -i it would output all dots for the unchanged
1981: attributes of a hard-link; it now changes those dots to spaces, as is
1982: done for other totally unchanged items.
1983:
1984: - When backing up a changed symlink or device, get rid of any old backup
1985: item so that we don't get an "already exists" error.
1986:
1987: - A couple places that were comparing a local and a remote modification-
1988: time were not honoring the --modify-window option.
1989:
1990: - Fixed a bug where the 'p' (permissions) itemized-changes flag might get
1991: set too often (if some non-significant mode bits differed).
1992:
1993: - Fixed a really old, minor bug that could cause rsync to warn about being
1994: unable to mkdir() a path that ends in "/." because it just created the
1995: directory (required --relative, --no-implied-dirs, a source path that
1996: ended in either a trailing slash or a trailing "/.", and a non-existing
1997: destination dir to tickle the bug in a recent version).
1998:
1999: ENHANCEMENTS:
2000:
2001: - Made the "max verbosity" setting in the rsyncd.conf file settable on a
2002: per-module basis (which now matches the documentation).
2003:
2004: - The support/rrsync script has been upgraded to verify the args of options
2005: that take args (instead of rejecting any such options). The script was
2006: also changed to try to be more secure and to fix a problem in the parsing
2007: of a pull operation that has multiple sources.
2008:
2009: - Improved the documentation that explains the difference between a
2010: normal daemon transfer and a daemon-over remote-shell transfer.
2011:
2012: - Some of the diffs supplied in the patches dir were fixed and/or
2013: improved.
2014:
2015: BUILD CHANGES:
2016:
2017: - Made configure define NOBODY_USER (currently hard-wired to "nobody") and
2018: NOBODY_GROUP (set to either "nobody" or "nogroup" depending on what we
2019: find in the /etc/group file).
2020:
2021: - Added a test to the test suite, itemized.test, that tests the output of
2022: -i (log-format w/%i) and some double-verbose messages.
2023:
2024:
2025: NEWS for rsync 2.6.5 (1 Jun 2005)
2026: Protocol: 29 (unchanged)
2027: Changes since 2.6.4:
2028:
2029: OUTPUT CHANGES:
2030:
2031: - Non-printable chars in filenames are now output using backslash-
2032: escaped characters rather than '?'s. Any non-printable character is
2033: output using 3 digits of octal (e.g. "\n" -> "\012"), and a backslash
2034: is now output as "\\". Rsync also uses your locale setting, which
2035: can make it treat fewer high-bit characters as non-printable.
2036:
2037: - If rsync received an empty file-list when pulling files, it would
2038: output a "nothing to do" message and exit with a 0 (success) exit
2039: status, even if the remote rsync returned an error (it did not do
2040: this under the same conditions when pushing files). This was changed
2041: to make the pulling behavior the same as the pushing behavior: we
2042: now do the normal end-of-run outputting (depending on options) and
2043: exit with the appropriate exit status.
2044:
2045: BUG FIXES:
2046:
2047: - A crash bug was fixed when a daemon had its "path" set to "/", did
2048: not have chroot enabled, and used some anchored excludes in the
2049: rsyncd.conf file.
2050:
2051: - Fixed a bug in the transfer of a single file when -H is specified
2052: (rsync would either infinite loop or perhaps crash).
2053:
2054: - Fixed a case where the generator might try (and fail) to tweak the
2055: write-permissions of a read-only directory in list-only mode (this
2056: only caused an annoying warning message).
2057:
2058: - If --compare-dest or --link-dest uses a locally-copied file as the
2059: basis for an updated version, log this better when --verbose or -i
2060: is in effect.
2061:
2062: - Fixed the accidental disabling of --backup during the --delete-after
2063: processing.
2064:
2065: - Restored the ability to use the --address option in client mode (in
2066: addition to its use in daemon mode).
2067:
2068: - Make sure that some temporary progress information from the delete
2069: processing does not get left on the screen when it is followed by a
2070: newline.
2071:
2072: - When --existing skips a directory with extra verbosity, refer to it
2073: as a "directory", not a "file".
2074:
2075: - When transferring a single file to a different-named file, any
2076: generator messages that are source-file related no longer refer to
2077: the file by the destination filename.
2078:
2079: - Fixed a bug where hard-linking a group of files might fail if the
2080: generator hasn't created a needed destination directory yet.
2081:
2082: - Fixed a bug where a hard-linked group of files that is newly-linked
2083: to a file in a --link-dest dir doesn't link the files from the rest
2084: of the cluster.
2085:
2086: - When deleting files with the --one-file-system (-x) option set, rsync
2087: no longer tries to remove files from inside a mount-point on the
2088: receiving side. Also, we don't complain about being unable to remove
2089: the mount-point dir.
2090:
2091: - Fixed a compatibility problem when using --cvs-ignore (-C) and
2092: sending files to an older rsync without using --delete.
2093:
2094: - Make sure that a "- !" or "+ !" include/exclude pattern does not
2095: trigger the list-clearing action that is reserved for "!".
2096:
2097: - Avoid a timeout in the generator when the sender/receiver aren't
2098: handling the generator's checksum output quickly enough.
2099:
2100: - Fixed the omission of some directories in the delete processing when
2101: --relative (-R) was combined with a source path that had a trailing
2102: slash.
2103:
2104: - Fixed a case where rsync would erroneously delete some files and then
2105: re-transfer them when the options --relative (-R) and --recursive
2106: (-r) were both enabled (along with --delete) and a source path had a
2107: trailing slash.
2108:
2109: - Make sure that --max-size doesn't affect a device or a symlink.
2110:
2111: - Make sure that a system with a really small MAXPATHLEN does not cause
2112: the buffers in readfd_unbuffered() to be too small to receive normal
2113: messages. (This mainly affected Cygwin.)
2114:
2115: - If a source pathname ends with a filename of "..", treat it as if
2116: "../" had been specified (so that we don't copy files to the parent
2117: dir of the destination).
2118:
2119: - If --delete is combined with a file-listing rsync command (i.e. no
2120: transfer is happening), avoid outputting a warning that we couldn't
2121: delete anything.
2122:
2123: - If --stats is specified with --delete-after, ensure that all the
2124: "deleting" messages are output before the statistics.
2125:
2126: - Improved one "if" in the deletion code that was only checking errno
2127: for ENOTEMPTY when it should have also been checking for EEXIST (for
2128: compatibility with OS variations).
2129:
2130: ENHANCEMENTS:
2131:
2132: - Added the --only-write-batch=FILE option that may be used (instead
2133: of --write-batch=FILE) to create a batch file without doing any
2134: actual updating of the destination. This allows you to divert all
2135: the file-updating data away from a slow data link (as long as you
2136: are pushing the data to the remote server when creating the batch).
2137:
2138: - When the generator is taking a long time to fill up its output buffer
2139: (e.g. if the transferred files are few, small, or missing), it now
2140: periodically flushes the output buffer so that the sender/receiver
2141: can get started on the files sooner rather than later.
2142:
2143: - Improved the keep-alive code to handle a long silence between the
2144: sender and the receiver that can occur when the sender is receiving
2145: the checksum data for a large file.
2146:
2147: - Improved the auth-errors that are logged by the daemon to include
2148: some information on why the authorization failed: wrong user,
2149: password mismatch, etc. (The client-visible message is unchanged!)
2150:
2151: - Improved the client's handling of an "@ERROR" from a daemon so that
2152: it does not complain about an unexpectedly closed socket (since we
2153: really did expect the socket to close).
2154:
2155: - If the daemon can't open the log-file specified in rsyncd.conf, fall
2156: back to using syslog and log an appropriate warning. This is better
2157: than what was typically a totally silent (and fatal) failure (since a
2158: daemon is not usually run with the --no-detach option that was
2159: necessary to see the error on stderr).
2160:
2161: - The man pages now consistently refer to an rsync daemon as a "daemon"
2162: instead of a "server" (to distinguish it from the server process in a
2163: non-daemon transfer).
2164:
2165: - Made a small change to the rrsync script (restricted rsync -- in the
2166: support dir) to make a read-only server reject all --remove-* options
2167: when sending files (to future-proof it against the possibility of
2168: other similar options being added at some point).
2169:
2170: INTERNAL:
2171:
2172: - Rsync now calls setlocale(LC_CTYPE, ""). This enables isprint() to
2173: better discern which filename characters need to be escaped in
2174: messages (which should result in fewer escaped characters in some
2175: locales).
2176:
2177: - Improved the naming of the log-file open/reopen/close functions.
2178:
2179: - Removed some protocol-compatibility code that was only needed to help
2180: someone running a pre-release of 2.6.4.
2181:
2182: BUILD CHANGES:
2183:
2184: - Added configure option "--disable-locale" to disable any use of
2185: setlocale() in the binary.
2186:
2187: - Fixed a bug in the SUPPORT{,_HARD}_LINKS #defines which prevented
2188: rsync from being built without symlink or hard-link support.
2189:
2190: - Only #define HAVE_REMSH if it is going to be set to 1.
2191:
2192: - Configure now disables the use of mkstemp() under HP-UX (since they
2193: refuse to fix its broken handling of large files).
2194:
2195: - Configure now explicitly checks for the lseek64() function so that
2196: the code can use HAVE_LSEEK64 instead of inferring lseek64()'s
2197: presence based on the presence of the off64_t type.
2198:
2199: - Configure no longer mentions the change in the default remote-shell
2200: (from rsh to ssh) that occurred for the 2.6.0 release.
2201:
2202: - Some minor enhancements to the test scripts.
2203:
2204: - Added a few new *.diff files to the patches dir, including a patch
2205: that enables the optional copying of extended attributes.
2206:
2207:
2208: NEWS for rsync 2.6.4 (30 March 2005)
2209: Protocol: 29 (changed)
2210: Changes since 2.6.3:
2211:
2212: OUTPUT CHANGES:
2213:
2214: - When rsync deletes a directory and outputs a verbose message about
2215: it, it now appends a trailing slash to the name instead of (only
2216: sometimes) outputting a preceding "directory " string.
2217:
2218: - The --stats output will contain file-list time-statistics if both
2219: sides are 2.6.4, or if the local side is 2.6.4 and the files are
2220: being pushed (since the stats come from the sending side).
2221: (Requires protocol 29 for a pull.)
2222:
2223: - The "%o" (operation) log-format escape now has a third value (besides
2224: "send" and "recv"): "del." (with trailing dot to make it 4 chars).
2225: This changes the way deletions are logged in the daemon's log file.
2226:
2227: - When the --log-format option is combined with --verbose, rsync now
2228: avoids outputting the name of the file twice in most circumstances.
2229: As long as the --log-format item does not refer to any post-transfer
2230: items (such as %b or %c), the --log-format message is output prior to
2231: the transfer, so --verbose is now the equivalent of a --log-format of
2232: '%n%L' (which outputs the name and any link info). If the log output
2233: must occur after the transfer to be complete, the only time the name
2234: is also output prior to the transfer is when --progress was specified
2235: (so that the name will precede the progress stats, and the full
2236: --log-format output will come after).
2237:
2238: - Non-printable characters in filenames are replaced with a '?' to
2239: avoid corrupting the screen or generating empty lines in the output.
2240:
2241: BUG FIXES:
2242:
2243: - Restore the list-clearing behavior of "!" in a .cvsignore file (2.6.3
2244: was only treating it as a special token in an rsync include/exclude
2245: file).
2246:
2247: - The combination of --verbose and --dry-run now mentions the full list
2248: of changes that would be output without --dry-run.
2249:
2250: - Avoid a mkdir warning when removing a directory in the destination
2251: that already exists in the --backup-dir.
2252:
2253: - An OS that has a binary mode for its files (such as cygwin) needed
2254: setmode(fd, O_BINARY) called on the temp-file we opened with
2255: mkstemp(). (Fix derived from cygwin's 2.6.3 rsync package.)
2256:
2257: - Fixed a potential hang when verbosity is high, the client side is
2258: the sender, and the file-list is large.
2259:
2260: - Fixed a potential protocol-corrupting bug where the generator could
2261: merge a message from the receiver into the middle of a multiplexed
2262: packet of data if only part of that data had been written out to the
2263: socket when the message from the generator arrived.
2264:
2265: - We now check if the OS doesn't support using mknod() for creating
2266: FIFOs and sockets, and compile-in some compatibility code using
2267: mkfifo() and socket() when necessary.
2268:
2269: - Fixed an off-by-one error in the handling of --max-delete=N. Also,
2270: if the --max-delete limit is exceeded during a run, we now output a
2271: warning about this at the end of the run and exit with a new error
2272: code (25).
2273:
2274: - One place in the code wasn't checking if fork() failed.
2275:
2276: - The "ignore nonreadable" daemon parameter used to erroneously affect
2277: readable symlinks that pointed to a non-existent file.
2278:
2279: - If the OS does not have lchown() and a chown() of a symlink will
2280: affect the referent of a symlink (as it should), we no longer try
2281: to set the user and group of a symlink.
2282:
2283: - The generator now properly runs the hard-link loop and the dir-time
2284: rewriting loop after we're sure that the redo phase is complete.
2285:
2286: - When --backup was specified with --partial-dir=DIR, where DIR is a
2287: relative path, the backup code was erroneously trying to backup a
2288: file that was put into the partial-dir.
2289:
2290: - If a file gets resent in a single transfer and the --backup option is
2291: enabled along with --inplace, rsync no longer performs a duplicate
2292: backup (it used to overwrite the first backup with the failed file).
2293:
2294: - One call to flush_write_file() was not being checked for an error.
2295:
2296: - The --no-relative option was not being sent from the client to a
2297: server sender.
2298:
2299: - If an rsync daemon specified "dont compress = ..." for a file and the
2300: client tried to specify --compress, the libz code was not handling a
2301: compression level of 0 properly. This could cause a transfer failure
2302: if the block-size for a file was large enough (e.g. rsync might have
2303: exited with an error for large files).
2304:
2305: - Fixed a bug that would sometimes surface when using --compress and
2306: sending a file with a block-size larger than 64K (either manually
2307: specified, or computed due to the file being really large). Prior
2308: versions of rsync would sometimes fail to decompress the data
2309: properly, and thus the transferred file would fail its verification.
2310:
2311: - If a daemon can't open the specified log file (i.e. syslog is not
2312: being used), die without crashing. We also output an error about
2313: the failure on stderr (which will only be seen if --no-detach was
2314: specified) and exit with a new error code (6).
2315:
2316: - A local transfer no longer duplicates all its include/exclude options
2317: (since the forked process already has a copy of the exclude list,
2318: there's no need to send them a set of duplicates).
2319:
2320: - The output of the items that are being updated by the generator (dirs,
2321: symlinks, devices) is now intermingled in the proper order with the
2322: output from the items that the receiver is updating (regular files)
2323: when pulling. This misordering was particularly bad when --progress
2324: was specified. (Requires protocol 29.)
2325:
2326: - When --timeout is specified, lulls that occur in the transfer while
2327: the generator is doing work that does not generate socket traffic
2328: (looking for changed files, deleting files, doing directory-time
2329: touch-ups, etc.) will cause a new keep-alive packet to be sent that
2330: should keep the transfer going as long as the generator continues to
2331: make progress. (Requires protocol 29.)
2332:
2333: - The stat size of a device is not added to the total file size of the
2334: items in the transfer (the size might be undefined on some OSes).
2335:
2336: - Fixed a problem with refused-option messages sometimes not making it
2337: back to the client side when a remote --files-from was in effect and
2338: the daemon was the receiver.
2339:
2340: - The --compare-dest option was not updating a file that differed in
2341: (the preserved) attributes from the version in the compare-dest DIR.
2342:
2343: - When rsync is copying files into a write-protected directory, fixed
2344: the change-report output for the directory so that we don't report
2345: an identical directory as changed.
2346:
2347: ENHANCEMENTS:
2348:
2349: - Rsync now supports popt's option aliases, which means that you can
2350: use /etc/popt and/or ~/.popt to create your own option aliases.
2351:
2352: - Added the --delete-during (--del) option which will delete files
2353: from the receiving side incrementally as each directory in the
2354: transfer is being processed. This makes it more efficient than the
2355: default, before-the-transfer behavior, which is now also available as
2356: --delete-before (and is still the default --delete-WHEN option that
2357: will be chosen if --delete or --delete-excluded is specified without
2358: a --delete-WHEN choice). All the --del* options infer --delete, so
2359: an rsync daemon that refuses "delete" will still refuse to allow any
2360: file-deleting options (including the new --remove-sent-files option).
2361:
2362: - All the --delete-WHEN options are now more memory efficient:
2363: Previously an duplicate set of file-list objects was created on the
2364: receiving side for the entire destination hierarchy. The new
2365: algorithm only creates one directory of objects at a time (for files
2366: inside the transfer).
2367:
2368: - Added the --copy-dest option, which works like --link-dest except
2369: that it locally copies identical files instead of hard-linking them.
2370:
2371: - Added support for specifying multiple --compare-dest, --copy-dest, or
2372: --link-dest options, but only of a single type. (Promoted from the
2373: patches dir and enhanced.) (Requires protocol 29.)
2374:
2375: - Added the --max-size option. (Promoted from the patches dir.)
2376:
2377: - The daemon-mode options are now separated from the normal rsync
2378: options so that they can't be mixed together. This makes it
2379: impossible to start a daemon that has improper default option values
2380: (which could cause problems when a client connects, such as hanging
2381: or crashing).
2382:
2383: - The --bwlimit option may now be used in combination with --daemon
2384: to specify both a default value for the daemon side and a value
2385: that cannot be exceeded by a user-specified --bwlimit option.
2386:
2387: - Added the "port" parameter to the rsyncd.conf file. (Promoted from
2388: the patches dir.) Also added "address". The command-line options
2389: take precedence over a config-file option, as expected.
2390:
2391: - In _exit_cleanup(): when we are exiting with a partially-received
2392: file, we now flush any data in the write-cache before closing the
2393: partial file.
2394:
2395: - The --inplace support was enhanced to work with --compare-dest,
2396: --link-dest, and (the new) --copy-dest options. (Requires protocol
2397: 29.)
2398:
2399: - Added the --dirs (-d) option for an easier way to copy directories
2400: without recursion. Any directories that are encountered are created
2401: on the destination. Specifying a directory with a trailing slash
2402: copies its immediate contents to the destination.
2403:
2404: - The --files-from option now implies --dirs (-d).
2405:
2406: - Added the --list-only option, which is mainly a way for the client to
2407: put the server into listing mode without needing to resort to any
2408: internal option kluges (e.g. the age-old use of "-r --exclude="/*/*"
2409: for a non-recursive listing). This option is used automatically
2410: (behind the scenes) when a modern rsync speaks to a modern daemon,
2411: but may also be specified manually if you want to force the use of
2412: the --list-only option over a remote-shell connection.
2413:
2414: - Added the --omit-dir-times (-O) option, which will avoid updating
2415: the modified time for directories when --times was specified. This
2416: option will avoid an extra pass through the file-list at the end of
2417: the transfer (to tweak all the directory times), which may provide
2418: an appreciable speedup for a really large transfer. (Promoted from
2419: the patches dir.)
2420:
2421: - Added the --filter (-f) option and its helper option, -F. Filter
2422: rules are an extension to the existing include/exclude handling
2423: that also supports nested filter files as well as per-directory
2424: filter files (like .cvsignore, but with full filter-rule parsing).
2425: This new option was chosen in order to ensure that all existing
2426: include/exclude processing remained 100% compatible with older
2427: versions. Protocol 29 is needed for full filter-rule support, but
2428: backward-compatible rules work with earlier protocol versions.
2429: (Promoted from the patches dir and enhanced.)
2430:
2431: - Added the --delay-updates option that puts all updated files into
2432: a temporary directory (by default ".~tmp~", but settable via the
2433: --partial-dir=DIR option) until the end of the transfer. This
2434: makes the updates a little more atomic for a large transfer.
2435:
2436: - If rsync is put into the background, any output from --progress is
2437: reduced.
2438:
2439: - Documented the "max verbosity" setting for rsyncd.conf. (This
2440: setting was added a couple releases ago, but left undocumented.)
2441:
2442: - The sender and the generator now double-check the file-list index
2443: they are given, and refuse to try to do a file transfer on a
2444: non-file index (since that would indicate that something had gone
2445: very wrong).
2446:
2447: - Added the --itemize-changes (-i) option, which is a way to output a
2448: more detailed list of what files changed and in what way. The effect
2449: is the same as specifying a --log-format of "%i %n%L" (see both the
2450: rsync and rsyncd.conf manpages). Works with --dry-run too.
2451:
2452: - Added the --fuzzy (-y) option, which attempts to find a basis file
2453: for a file that is being created from scratch. The current algorithm
2454: only looks in the destination directory for the created file, but it
2455: does attempt to find a match based on size/mod-time (in case the file
2456: was renamed with no other changes) as well as based on a fuzzy
2457: name-matching algorithm. This option requires protocol 29 because it
2458: needs the new file-sorting order. (Promoted from patches dir and
2459: enhanced.) (Requires protocol 29.)
2460:
2461: - Added the --remove-sent-files option, which lets you move files
2462: between systems.
2463:
2464: - The hostname in HOST:PATH or HOST::PATH may now be an IPv6 literal
2465: enclosed in '[' and ']' (e.g. "[::1]"). (We already allowed IPv6
2466: literals in the rsync://HOST:PORT/PATH format.)
2467:
2468: - When rsync recurses to build the file list, it no longer keeps open
2469: one or more directory handles from the dir's parent dirs.
2470:
2471: - When building under windows, the default for --daemon is now to
2472: avoid detaching, requiring the new --detach option to force rsync
2473: to detach.
2474:
2475: - The --dry-run option can now be combined with either --write-batch or
2476: --read-batch, allowing you to run a do-nothing test command to see
2477: what would happen without --dry-run.
2478:
2479: - The daemon's "read only" config item now sets an internal read_only
2480: variable that makes extra sure that no write/delete calls on the
2481: read-only side can succeed.
2482:
2483: - The log-format % escapes can now have a numeric field width in
2484: between the % and the escape letter (e.g. "%-40n %08p").
2485:
2486: - Improved the option descriptions in the --help text.
2487:
2488: SUPPORT FILES:
2489:
2490: - Added atomic-rsync to the support dir: a perl script that will
2491: transfer some files using rsync, and then move the updated files into
2492: place all at once at the end of the transfer. Only works when
2493: pulling, and uses --link-dest and a parallel hierarchy of files to
2494: effect its update.
2495:
2496: - Added mnt-excl to the support dir: a perl script that takes the
2497: /proc/mounts file and translates it into a set of excludes that will
2498: exclude all mount points (even mapped mounts to the same disk). The
2499: excludes are made relative to the specified source dir and properly
2500: anchored.
2501:
2502: - Added savetransfer.c to the support dir: a C program that can make
2503: a copy of all the data that flows over the wire. This lets you test
2504: for data corruption (by saving the data on both the sending side and
2505: the receiving side) and provides one way to debug a protocol error.
2506:
2507: - Added rrsync to the support dir: this is an updated version of Joe
2508: Smith's restricted rsync perl script. This helps to ensure that only
2509: certain rsync commands can be run by an ssh invocation.
2510:
2511: INTERNAL:
2512:
2513: - Added better checking of the checksum-header values that come over
2514: the socket.
2515:
2516: - Merged a variety of file-deleting functions into a single function so
2517: that it is easier to maintain.
2518:
2519: - Improved the type of some variables (particularly blocksize vars) for
2520: consistency and proper size.
2521:
2522: - Got rid of the uint64 type (which we didn't need).
2523:
2524: - Use a slightly more compatible set of core #include directives.
2525:
2526: - Defined int32 in a way that ensures that the build dies if we can't
2527: find a variable with at least 32 bits.
2528:
2529: PROTOCOL DIFFERENCES FOR VERSION 29:
2530:
2531: - A 16-bit flag-word is transmitted after every file-list index. This
2532: indicates what is changing between the sender and the receiver. The
2533: generator now transmits an index and a flag-word to indicate when
2534: dirs and symlinks have changed (instead of producing a message),
2535: which makes the outputting of the information more consistent and
2536: less prone to screen corruption (because the local receiver/sender is
2537: now outputting all the file-change info messages).
2538:
2539: - If a file is being hard-linked, the ITEM_XNAME_FOLLOWS bit is enabled
2540: in the flag-word and the name of the file that was linked immediately
2541: follows in vstring format (see below).
2542:
2543: - If a file is being transferred with an alternate-basis file, the
2544: ITEM_BASIS_TYPE_FOLLOWS bit is enabled in the flag-word and a single
2545: byte follows, indicating what type of basis file was chosen. If that
2546: indicates that a fuzzy-match was selected, the ITEM_XNAME_FOLLOWS bit
2547: is set in the flag-word and the name of the match in vstring format
2548: follows the basis byte. A vstring is a variable length string that
2549: has its size written prior to the string, and no terminating null.
2550: If the string is from 1-127 bytes, the length is a single byte. If
2551: it is from 128-32767 bytes, the length is written as ((len >> 8) |
2552: 0x80) followed by (len % 0x100).
2553:
2554: - The sending of exclude names is done using filter-rule syntax. This
2555: means that all names have a prefixed rule indicator, even excludes
2556: (which used to be sent as a bare pattern, when possible). The -C
2557: option will include the per-dir .cvsignore merge file in the list of
2558: filter rules so it is positioned correctly (unlike in some older
2559: transfer scenarios).
2560:
2561: - Rsync sorts the filename list in a different way: it sorts the subdir
2562: names after the non-subdir names for each dir's contents, and it
2563: always puts a dir's contents immediately after the dir's name in the
2564: list. (Previously an item named "foo.txt" would sort in between
2565: directory "foo/" and "foo/bar".)
2566:
2567: - When talking to a protocol 29 rsync daemon, a list-only request
2568: is able to note this before the options are sent over the wire and
2569: the new --list-only option is included in the options.
2570:
2571: - When the --stats bytes are sent over the wire (or stored in a batch),
2572: they now include two elapsed-time values: one for how long it took to
2573: build the file-list, and one for how long it took to send it over the
2574: wire (each expressed in thousandths of a second).
2575:
2576: - When --delete-excluded is specified with some filter rules (AKA
2577: excludes), a client sender will now initiate a send of the rules to
2578: the receiver (older protocols used to omit the sending of excludes in
2579: this situation since there were no receiver-specific rules that
2580: survived --delete-excluded back then). Note that, as with all the
2581: filter-list sending, only items that are significant to the other
2582: side will actually be sent over the wire, so the filter-rule list
2583: that is sent in this scenario is often empty.
2584:
2585: - An index equal to the file-list count is sent as a keep-alive packet
2586: from the generator to the sender, which then forwards it on to the
2587: receiver. This normally invalid index is only a valid keep-alive
2588: packet if the 16-bit flag-word that follows it contains a single bit
2589: (ITEM_IS_NEW, which is normally an illegal flag to appear alone).
2590:
2591: - A protocol-29 batch file includes a bit for the setting of the --dirs
2592: option and for the setting of the --compress option. Also, the shell
2593: script created by --write-batch will use the --filter option instead
2594: of --exclude-from to capture any filter rules.
2595:
2596: BUILD CHANGES:
2597:
2598: - Handle an operating system that use mkdev() in place of makedev().
2599:
2600: - Improved configure to better handle cross-compiling.
2601:
2602:
2603: NEWS for rsync 2.6.3 (30 Sep 2004)
2604: Protocol: 28 (unchanged)
2605: Changes since 2.6.2:
2606:
2607: SECURITY FIXES:
2608:
2609: - A bug in the sanitize_path routine (which affects a non-chrooted
2610: rsync daemon) could allow a user to craft a pathname that would get
2611: transformed into an absolute path for certain options (but not for
2612: file-transfer names). If you're running an rsync daemon with chroot
2613: disabled, *please upgrade*, ESPECIALLY if the user privs you run
2614: rsync under is anything above "nobody".
2615:
2616: OUTPUT CHANGES (ATTN: those using a script to parse the verbose output):
2617:
2618: - Please note that the 2-line footer (output when verbose) now uses the
2619: term "sent" instead of "wrote" and "received" instead of "read". If
2620: you are not parsing the numeric values out of this footer, a script
2621: would be better off using the empty line prior to the footer as the
2622: indicator that the verbose output is over.
2623:
2624: - The output from the --stats option was similarly affected to change
2625: "written" to "sent" and "read" to "received".
2626:
2627: - Rsync ensures that a filename that contains a newline gets mentioned
2628: with each newline transformed into a question mark (which prevents a
2629: filename from causing an empty line to be output).
2630:
2631: - The "backed up ..." message that is output when at least 2 --verbose
2632: options are specified is now the same both with and without the
2633: --backup-dir option.
2634:
2635: BUG FIXES:
2636:
2637: - Fixed a crash bug that might appear when --delete was used and
2638: multiple source directories were specified.
2639:
2640: - Fixed a 32-bit truncation of the file length when generating the
2641: checksums.
2642:
2643: - The --backup code no longer attempts to create some directories
2644: over and over again (generating warnings along the way).
2645:
2646: - Fixed a bug in the reading of the secrets file (by the daemon) and
2647: the password file (by the client): the files no longer need to be
2648: terminated by a newline for their content to be read in.
2649:
2650: - If a file has a read error on the sending side or the reconstructed
2651: data doesn't match the expected checksum (perhaps due to the basis
2652: file changing during the transfer), the receiver will no longer
2653: retain the resulting file unless the --partial option was specified.
2654: (Note: for the read-error detection to work, neither side can be
2655: older than 2.6.3 -- older receivers will always retain the file, and
2656: older senders don't tell the receiver that the file had a read
2657: error.)
2658:
2659: - If a file gets resent in a single transfer and the --backup option
2660: is enabled, rsync no longer performs a duplicate backup (it used to
2661: overwrite the original file in the backup area).
2662:
2663: - Files specified in the daemon's "exclude" or "exclude from" config
2664: items are now excluded from being uploaded (assuming that the module
2665: allows uploading at all) in addition to the old download exclusion.
2666:
2667: - Got rid of a potential hang in the receiver when near the end of a
2668: phase.
2669:
2670: - When using --backup without a --backup-dir, rsync no longer preserves
2671: the modify time on directories. This avoids confusing NFS.
2672:
2673: - When --copy-links (-L) is specified, we now output a separate error
2674: for a symlink that has no referent instead of claiming that a file
2675: "vanished".
2676:
2677: - The --copy-links (-L) option no longer has the side-effect of telling
2678: the receiving side to follow symlinks. See the --keep-dirlinks
2679: option (mentioned below) for a way to specify that behavior.
2680:
2681: - Error messages from the daemon server's option-parsing (such as
2682: refused options) are now successfully transferred back to the client
2683: (the server used to fail to send the message because the socket
2684: wasn't in the right state for the message to get through).
2685:
2686: - Most transfer errors that occur during a daemon transfer are now
2687: returned to the user in addition to being logged (some messages are
2688: intended to be daemon-only and are not affected by this).
2689:
2690: - Fixed a bug in the daemon authentication code when using one of the
2691: batch-processing options.
2692:
2693: - We try to work around some buggy IPv6 implementations that fail to
2694: implement IPV6_V6ONLY. This should fix the "address in use" error
2695: that some daemons get when running on an OS with a buggy IPv6
2696: implementation. Also, if the new code gets this error, we might
2697: suggest that the user specify --ipv4 or --ipv6 (if we think it will
2698: help).
2699:
2700: - When the remote rsync dies, make a better effort to recover any error
2701: messages it may have sent before dying (the local rsync used to just
2702: die with a socket-write error).
2703:
2704: - When using --delete and a --backup-dir that contains files that are
2705: hard-linked to their destination equivalents, rsync now makes sure
2706: that removed files really get removed (avoids a really weird rename()
2707: behavior).
2708:
2709: - Avoid a bogus run-time complaint about a lack of 64-bit integers when
2710: the int64 type is defined as an off_t and it actually has 64-bits.
2711:
2712: - Added a configure check for open64() without mkstemp64() so that we
2713: can avoid using mkstemp() when such a combination is encountered.
2714: This bypasses a problem writing out large temp files on OSes such as
2715: AIX and HP-UX.
2716:
2717: - Fixed an age-old crash problem with --read-batch on a local copy
2718: (rsync was improperly assuming --whole-file for the local copy).
2719:
2720: - When --dry-run (-n) is used and the destination directory does not
2721: exist, rsync now produces a correct report of files that would be
2722: sent instead of dying with a chdir() error.
2723:
2724: - Fixed a bug that could cause a slow-to-connect rsync daemon to die
2725: with an error instead of waiting for the connection to finish.
2726:
2727: - Fixed an ssh interaction that could cause output to be lost when the
2728: user chose to combine the output of rsync's stdout and stderr (e.g.
2729: using the "2>&1").
2730:
2731: - Fixed an option-parsing bug when --files-from got passed to a daemon.
2732:
2733: ENHANCEMENTS:
2734:
2735: - Added the --partial-dir=DIR option that lets you specify where to
2736: (temporarily) put a partially transferred file (instead of over-
2737: writing the destination file). E.g. --partial-dir=.rsync-partial
2738: Also added support for the RSYNC_PARTIAL_DIR environment variable
2739: that, when found, transforms a regular --partial option (such as
2740: the convenient -P option) into one that also specifies a directory.
2741:
2742: - Added --keep-dirlinks (-K), which allows you to symlink a directory
2743: onto another partition on the receiving side and have rsync treat it
2744: as matching a normal directory from the sender.
2745:
2746: - Added the --inplace option that tells rsync to write each destination
2747: file without using a temporary file. The matching of existing data
2748: in the destination file can be severely limited by this, but there
2749: are also cases where this is more efficient (such as appending data).
2750: Use only when needed (see the man page for more details).
2751:
2752: - Added the "write only" option for the daemon's config file.
2753:
2754: - Added long-option names for -4 and -6 (namely --ipv4 and --ipv6)
2755: and documented all these options in the man page.
2756:
2757: - Improved the handling of the --bwlimit option so that it's less
2758: bursty, more accurate, and works properly over a larger range of
2759: values.
2760:
2761: - The rsync daemon-over-ssh code now looks for SSH_CONNECTION and
2762: SSH2_CLIENT in addition to SSH_CLIENT to figure out the IP address.
2763:
2764: - Added the --checksum-seed=N option for advanced users.
2765:
2766: - Batch writing/reading has a brand-new implementation that is simpler,
2767: fixes a few weird problems with the old code (such as no longer
2768: sprinkling the batch files into different dirs or even onto different
2769: systems), and is much less intrusive into the code (making it easier
2770: to maintain for the future). The new code generates just one data
2771: file instead of three, which makes it possible to read the batch on
2772: stdin via a remote shell. Also, the old requirement of forcing the
2773: same fixed checksum-seed for all batch processing has been removed.
2774:
2775: - If an rsync daemon has a module set with "list = no" (which hides its
2776: presence in the list of available modules), a user that fails to
2777: authenticate gets the same "unknown module" error that they would get
2778: if the module were actually unknown (while still logging the real
2779: error to the daemon's log file). This prevents fishing for module
2780: names.
2781:
2782: - The daemon's "refuse options" config item now allows you to match
2783: option names using wildcards and/or the single-letter option names.
2784:
2785: - Each transferred file now gets its permissions and modified-time
2786: updated before the temp-file gets moved into place. Previously, the
2787: finished file would have a very brief window where its permissions
2788: disallowed all group and world access.
2789:
2790: - Added the ability to parse a literal IPv6 address in an "rsync:" URL
2791: (e.g. rsync://[2001:638:500:101::21]:873/module/dir).
2792:
2793: - The daemon's wildcard expanding code can now handle more than 1000
2794: filenames (it's now limited by memory instead of having a hard-wired
2795: limit).
2796:
2797: INTERNAL:
2798:
2799: - Some cleanup in the exclude code has saved some per-exclude memory
2800: and made the code easier to maintain.
2801:
2802: - Improved the argv-overflow checking for a remote command that has a
2803: lot of args.
2804:
2805: - Use rsyserr() in the various places that were still calling rprintf()
2806: with strerror() as an arg.
2807:
2808: - If an rsync daemon is listening on multiple sockets (to handle both
2809: IPv4 and IPv6 to a single port), we now close all the unneeded file
2810: handles after we accept a connection (we used to close just one of
2811: them).
2812:
2813: - Optimized the handling of larger block sizes (rsync used to slow to a
2814: crawl if the block size got too large).
2815:
2816: - Optimized away a loop in hash_search().
2817:
2818: - Some improvements to the sanitize_path() and clean_fname() functions
2819: makes them more efficient and produce better results (while still
2820: being compatible with the file-name cleaning that gets done on both
2821: sides when sending the file-list).
2822:
2823: - Got rid of alloc_sanitize_path() after adding a destination-buffer
2824: arg to sanitize_path() made it possible to put all the former's
2825: functionality into the latter.
2826:
2827: - The file-list that is output when at least 4 verbose options are
2828: specified reports the uid value on the sender even when rsync is
2829: not running as root (since we might be sending to a root receiver).
2830:
2831: BUILD CHANGES:
2832:
2833: - Added a "gen" target to rebuild most of the generated files,
2834: including configure, config.h.in, the man pages, and proto.h.
2835:
2836: - If "make proto" doesn't find some changes in the prototypes, the
2837: proto.h file is left untouched (its time-stamp used to always be
2838: updated).
2839:
2840: - The variable $STRIP (that is optionally set by the install-strip
2841: target's rule) was changed to $INSTALL_STRIP because some systems
2842: have $STRIP already set in the environment.
2843:
2844: - Fixed a build problem when SUPPORT_HARD_LINKS isn't defined.
2845:
2846: - When cross-compiling, the gettimeofday() function is now assumed to
2847: be a modern version that takes two-args (since we can't test it).
2848:
2849: DEVELOPER RELATED:
2850:
2851: - The scripts in the testsuite dir were cleaned up a bit and a few
2852: new tests added.
2853:
2854: - Some new diffs were added to the patches dir, and some accepted
2855: ones were removed.

2858: NEWS for rsync 2.6.2 (30 Apr 2004)
2859: Protocol: 28 (unchanged)
2860: Changes since 2.6.1:
2861:
2862: BUG FIXES:
2863:
2864: - Fixed a major bug in the sorting of the filenames when --relative
2865: is used for some sources (just sources such as "/" and "/*" were
2866: affected). This fix ensures that we ask for the right file-list
2867: item when requesting changes from the sender.
2868:
2869: - Rsync now checks the return value of the close() function to
2870: better report disk-full problems on an NFS file system.
2871:
2872: - Restored the old daemon-server behavior of logging error messages
2873: rather than returning them to the user. (A better long-term fix
2874: will be sought in the future.)
2875:
2876: - An obscure uninitialized-variable bug was fixed in the uid/gid
2877: code. (This bug probably had no ill effects.)
2878:
2879: BUILD CHANGES:
2880:
2881: - Got rid of the configure check for sys/sysctl.h (it wasn't used
2882: and was causing a problem on some systems). Also improved the
2883: broken-largefile-locking test to try to avoid failure due to an
2884: NFS build-dir.
2885:
2886: - Fixed a compile problem on systems that don't define
2887: AI_NUMERICHOST.
2888:
2889: - Fixed a compile problem in the popt source for compilers that
2890: don't support __attribute__.
2891:
2892: DEVELOPER RELATED:
2893:
2894: - Improved the testsuite's "merge" test to work on OSF1.
2895:
2896: - Two new diffs were added to the patches dir.
2897:
2898:
2899: NEWS for rsync 2.6.1 (26 Apr 2004)
2900: Protocol: 28 (changed)
2901: Changes since 2.6.0:
2902:
2903: SECURITY FIXES:
2904:
2905: - Paths sent to an rsync daemon are more thoroughly sanitized when
2906: chroot is not used. If you're running a non-read-only rsync
2907: daemon with chroot disabled, *please upgrade*, ESPECIALLY if the
2908: user privs you run rsync under is anything above "nobody".
2909:
2910: ENHANCEMENTS:
2911:
2912: - Lower memory use, more optimal transfer of data over the socket,
2913: and lower CPU usage (see the INTERNAL section for details).
2914:
2915: - The RSYNC_PROXY environment variable can now contain a
2916: "USER:PASS@" prefix before the "HOST:PORT" information.
2917: (Bardur Arantsson)
2918:
2919: - The --progress output now mentions how far along in the transfer
2920: we are, including both a count of files transferred and a
2921: percentage of the total file-count that we've processed. It also
2922: shows better current-rate-of-transfer and remaining-transfer-time
2923: values.
2924:
2925: - Documentation changes now attempt to describe some often mis-
2926: understood features more clearly.
2927:
2928: BUG FIXES:
2929:
2930: - When -x (--one-file-system) is combined with -L (--copy-links) or
2931: --copy-unsafe-links, no symlinked files are skipped, even if the
2932: referent file is on a different filesystem.
2933:
2934: - The --link-dest code now works properly for a non-root user when
2935: (1) the UIDs of the source and destination differ and -o was
2936: specified, or (2) when the group of the source can't be used on
2937: the destination and -g was specified.
2938:
2939: - Fixed a bug in the handling of -H (hard-links) that might cause
2940: the expanded PATH/NAME value of the current item to get
2941: overwritten (due to an expanded-name caching bug).
2942:
2943: - We now reset the "new data has been sent" flag at the start of
2944: each file we send. This makes sure that an interrupted transfer
2945: with the --partial option set doesn't keep a shorter temp file
2946: than the current basis file when no new data has been transferred
2947: over the wire for that file.
2948:
2949: - Fixed a byte-order problem in --batch-mode on big-endian machines.
2950: (Jay Fenlason)
2951:
2952: - When using --cvs-exclude, the exclude items we get from a
2953: per-directory's .cvsignore file once again only affect that one
2954: directory (not all following directories too). The items are also
2955: now properly word-split and parsed without any +/- prefix parsing.
2956:
2957: - When specifying the USER@HOST: prefix for a file, the USER part
2958: can now contain an '@', if needed (i.e. the last '@' is used to
2959: find the HOST, not the first).
2960:
2961: - Fixed some bugs in the handling of group IDs for non-root users:
2962: (1) It properly handles a group that the sender didn't have a name
2963: for (it would previously skip changing the group on any files in
2964: that group). (2) If --numeric-ids is used, rsync no longer
2965: attempts to set groups that the user doesn't have the permission
2966: to set.
2967:
2968: - Fixed the "refuse options" setting in the rsyncd.conf file.
2969:
2970: - Improved the -x (--one-file-system) flag's handling of any mount-
2971: point directories we encounter. It is both more optimal (in that
2972: it no longer does a useless scan of the contents of the mount-
2973: point dirs) and also fixes a bug where a remapped mount of the
2974: original filesystem could get discovered in a subdir we should be
2975: ignoring.
2976:
2977: - Rsync no longer discards a double-slash at the start of a filename
2978: when trying to open the file. It also no longer constructs names
2979: that start with a double slash (unless the user supplied them).
2980:
2981: - Path-specifying options to a daemon should now work the same with
2982: or without chroot turned on. Previously, such a option (such as
2983: --link-dest) would get its absolute path munged into a relative
2984: one if chroot was not on, making that setting fairly useless.
2985: Rsync now transforms the path into one that is based on the
2986: module's base dir when chroot is not enabled.
2987:
2988: - Fixed a compatibility problem interacting with older rsync
2989: versions that might send us an empty --suffix value without
2990: telling us that --backup-dir was specified.
2991:
2992: - The "hosts allow" option for a daemon-over-remote-shell process
2993: now has improved support for IPv6 addresses and a fix for systems
2994: that have a length field in their socket structs.
2995:
2996: - Fixed the ability to request an empty backup --suffix when sending
2997: files to an rsync daemon.
2998:
2999: - Fixed an option-parsing bug when --files-from was sent to a server
3000: sender.
3001:
3002: INTERNAL:
3003:
3004: - Most of the I/O is now buffered, which results in a pretty large
3005: speedup when running under MS Windows. (Craig Barratt)
3006:
3007: - Optimizations to the name-handling/comparing code have made some
3008: significant reductions in user-CPU time for large file sets.
3009:
3010: - Some cleanup of the variable types make the code more consistent.
3011:
3012: - Reduced memory requirements of hard link preservation.
3013: (J.W. Schultz)
3014:
3015: - Implemented a new algorithm for hard-link handling that speeds up
3016: the code significantly. (J.W. Schultz and Wayne Davison)
3017:
3018: - The --hard-link option now uses the first existing file in the
3019: group of linked files as the basis for the transfer. This
3020: prevents the sub-optimal transfer of a file's data when a new
3021: hardlink is added on the sending side and it sorts alphabetically
3022: earlier in the list than the files that are already present on the
3023: receiving side.
3024:
3025: - Dropped support for protocol versions less than 20 (2.3.0 released
3026: 15 Mar 1999) and activated warnings for protocols less than 25
3027: (2.5.0 released 23 Aug 2001). (Wayne Davison and J.W. Schultz,
3028: severally)
3029:
3030: - More optimal data transmission for --hard-links (protocol 28).
3031:
3032: - More optimal data transmission for --checksum (protocol 28).
3033:
3034: - Less memory is used when --checksum is specified.
3035:
3036: - Less memory is used in the file list (a per-file savings).
3037:
3038: - The generator is now better about not modifying the file list
3039: during the transfer in order to avoid a copy-on-write memory
3040: bifurcation (on systems where fork() uses shared memory).
3041: Previously, rsync's shared memory would slowly become unshared,
3042: resulting in real memory usage nearly doubling on the receiving
3043: side by the end of the transfer. Now, as long as permissions
3044: are being preserved, the shared memory should remain that way
3045: for the entire transfer.
3046:
3047: - Changed hardlink info and file_struct + strings to use allocation
3048: pools. This reduces memory use for large file-sets and permits
3049: freeing memory to the OS. (J.W. Schultz)
3050:
3051: - The 2 pipes used between the receiver and generator processes
3052: (which are forked on the same machine) were reduced to 1 pipe and
3053: the protocol improved so that (1) it is now impossible to have the
3054: "redo" pipe fill up and hang rsync, and (2) trailing messages from
3055: the receiver don't get lost on their way through the generator
3056: over to the sender (which mainly affected hard-link messages and
3057: verbose --stats output).
3058:
3059: - Improved the internal uid/gid code to be more portable and a
3060: little more optimized.
3061:
3062: - The device numbers sent when using --devices are now sent as
3063: separate major/minor values with 32-bit accuracy (protocol 28).
3064: Previously, the copied devices were sent as a single 32-bit
3065: number. This will make inter-operation of 64-bit binaries more
3066: compatible with their 32-bit brethren (with both ends of the
3067: connection are using protocol 28). Note that optimizations in the
3068: binary protocol for sending the device numbers often results in
3069: fewer bytes being used than before, even though more precision is
3070: now available.
3071:
3072: - Some cleanup of the exclude/include structures and its code made
3073: things clearer (internally), simpler, and more efficient.
3074:
3075: - The reading & writing of the file-list in batch-mode is now
3076: handled by the same code that sends & receives the list over the
3077: wire. This makes it much easier to maintain. (Note that the
3078: batch code is still considered to be experimental.)
3079:
3080: BUILD CHANGES:
3081:
3082: - The configure script now accepts --with-rsyncd-conf=PATH to
3083: override the default value of the /etc/rsyncd.conf file.
3084:
3085: - Fixed configure bug when running "./configure --disable-ipv6".
3086:
3087: - Fixed compilation problem on Tru64 Unix (having to do with
3088: sockaddr.sa_len and sockaddr.sin_len).
3089:
3090: DEVELOPER RELATED:
3091:
3092: - Fixed "make test" bug when build dir is not the source dir.
3093:
3094: - Added a couple extra diffs in the "patches" dir, removed the ones
3095: that got applied, and rebuilt the rest.

3097:
3098: NEWS for rsync 2.6.0 (1 Jan 2004)
3099: Protocol: 27 (changed)
3100: Changes since 2.5.7:
3101:
3102: ENHANCEMENTS:
3103:
3104: * "ssh" is now the default remote shell for rsync. If you want to
3105: change this, configure like this: "./configure --with-rsh=rsh".
3106:
3107: * Added --files-from, --no-relative, --no-implied-dirs, and --from0.
3108: Note that --from0 affects the line-ending character for all the
3109: files read by the --*-from options. (Wayne Davison)
3110:
3111: * Length of csum2 is now per-file starting with protocol version
3112: 27. (J.W. Schultz)
3113:
3114: * Per-file dynamic block size is now sqrt(file length). The
3115: per-file checksum size is determined according to an algorithm
3116: provided by Donovan Baarda which reduces the probability of rsync
3117: algorithm corrupting data and falling back using the whole md4
3118: checksums. (J.W. Schultz, Donovan Baarda)
3119:
3120: * The --stats option no longer includes the (debug) malloc summary
3121: unless the verbose option was specified at least twice.
3122:
3123: * Added a new error/warning code for when files vanish from the
3124: sending side. Made vanished source files not interfere with the
3125: file-deletion pass when --delete-after was specified.
3126:
3127: * Various trailing-info sections are now preceded by a newline.
3128:
3129: BUG FIXES:
3130:
3131: * Fixed several exclude/include matching bugs when using wild-cards.
3132: This has a several user-visible effects, all of which make the
3133: matching more consistent and intuitive. This should hopefully not
3134: cause anyone problems since it makes the matching work more like
3135: what people are expecting. (Wayne Davison)
3136:
3137: - A pattern with a "**" no longer causes a "*" to match slashes.
3138: For example, with "/*/foo/**", "foo" must be 2 levels deep.
3139: [If your string has BOTH "*" and "**" wildcards, changing the
3140: "*" wildcards to "**" will provide the old behavior in all
3141: versions.]
3142:
3143: - "**/foo" now matches at the base of the transfer (like /foo
3144: does). [Use "/**/foo" to get the old behavior in all versions.]
3145:
3146: - A non-anchored wildcard term floats to match beyond the base of
3147: the transfer. E.g. "CVS/R*" matches at the end of the path,
3148: just like the non-wildcard term "CVS/Root" does. [Use "/CVS/R*"
3149: to get the old behavior in all versions.]
3150:
3151: - Including a "**" in the match term causes it to be matched
3152: against the entire path, not just the name portion, even if
3153: there aren't any interior slashes in the term. E.g. "foo**bar"
3154: would exclude "/path/foo-bar" (just like before) as well as
3155: "/foo-path/baz-bar" (unlike before). [Use "foo*bar" to get the
3156: old behavior in all versions.]
3157:
3158: * The exclude list specified in the daemon's config file is now
3159: properly applied to the pulled items no matter how deep the
3160: user's file-args are in the source tree. (Wayne Davison)
3161:
3162: * For protocol version >= 27, mdfour_tail() is called when the
3163: block size (including checksum_seed) is a multiple of 64.
3164: Previously it was not called, giving the wrong MD4 checksum.
3165: (Craig Barratt)
3166:
3167: * For protocol version >= 27, a 64 bit bit counter is used in
3168: mdfour.c as required by the RFC. Previously only a 32 bit bit
3169: counter was used, causing incorrect MD4 file checksums for
3170: file sizes >= 512MB - 4. (Craig Barratt)
3171:
3172: * Fixed a crash bug when interacting with older rsync versions and
3173: multiple files of the same name are destined for the same dir.
3174: (Wayne Davison)
3175:
3176: * Keep tmp names from overflowing MAXPATHLEN.
3177:
3178: * Make --link-dest honor the absence of -p, -o, and -g.
3179:
3180: * Made rsync treat a trailing slash in the destination in a more
3181: consistent manner.
3182:
3183: * Fixed file I/O error detection. (John Van Essen)
3184:
3185: * Fixed bogus "malformed address {hostname}" message in rsyncd log
3186: when checking IP address against hostnames from "hosts allow"
3187: and "hosts deny" parameters in config file.
3188:
3189: * Print heap statistics when verbose >= 2 instead of when >= 1.
3190:
3191: * Fixed a compression (-z) bug when syncing a mostly-matching file
3192: that contains already-compressed data. (Yasuoka Masahiko and
3193: Wayne Davison)
3194:
3195: * Fixed a bug in the --backup code that could cause deleted files
3196: to not get backed up.
3197:
3198: * When the backup code makes new directories, create them with mode
3199: 0700 instead of 0755 (since the directory permissions in the
3200: backup tree are not yet copied from the main tree).
3201:
3202: * Call setgroups() in a more portable manner.
3203:
3204: * Improved file-related error messages to better indicate exactly
3205: what pathname failed. (Wayne Davison)
3206:
3207: * Fixed some bugs in the handling of --delete and --exclude when
3208: using the --relative (-R) option. (Wayne Davison)
3209:
3210: * Fixed bug that prevented regular files from replacing
3211: special files and caused a directory in --link-dest or
3212: --compare-dest to block the creation of a file with the
3213: same path. A directory still cannot be replaced by a
3214: regular file unless --delete specified. (J.W. Schultz)
3215:
3216: * Detect and report when open or opendir succeed but read and
3217: readdir fail caused by network filesystem issues and truncated
3218: files. (David Norwood, Michael Brown, J.W. Schultz)
3219:
3220: * Added a fix that should give ssh time to restore the tty settings
3221: if the user presses Ctrl-C at an ssh password prompt.
3222:
3223: INTERNAL:
3224:
3225: * Eliminated vestigial support for old versions that we stopped
3226: supporting. (J.W. Schultz)
3227:
3228: * Simplified some of the option-parsing code. (Wayne Davison)
3229:
3230: * Some cleanup made to the exclude code, as well as some new
3231: defines added to enhance readability. (Wayne Davison)
3232:
3233: * Changed the protocol-version code so that it can interact at a
3234: lower protocol level than the maximum supported by both sides.
3235: Added an undocumented option, --protocol=N, to force the value
3236: we advertise to the other side (primarily for testing purposes).

3259: Zimmerman)
3260:
3261: * Combining "::" syntax with the --rsh/-e option now uses the
3262: specified remote-shell as a transport to talk to a (newly-spawned)
3263: server-daemon. This allows someone to use daemon features, such
3264: as modules, over a secure protocol, such as ssh. (JD Paul)
3265:
3266: * The rsync:// syntax for daemon connections is now accepted in the
3267: destination field.
3268:
3269: * If the file name given to --include-from or --exclude-from is "-",
3270: rsync will read from standard input. (J.W. Schultz)
3271:
3272: * New option --link-dest which is like --compare-dest except that
3273: unchanged files are hard-linked in to the destination directory.
3274: (J.W. Schultz)
3275:
3276: * Don't report an error if an excluded file disappears during an
3277: rsync run. (Eugene Chupriyanov and Bo Kersey)
3278:
3279: * Added .svn to --cvs-exclude list to support subversion. (Jon
3280: Middleton)
3281:
3282: * Properly support IPv6 addresses in the rsyncd.conf "hosts allow"
3283: and "hosts deny" fields. (Hideaki Yoshifuji)
3284:
3285: * Changed exclude file handling to permit DOS or MAC style line
3286: terminations. (J.W. Schultz)
3287:
3288: * Ignore errors from chmod when -p/-a/--preserve-perms is not set.
3289: (Dave Dykstra)
3290:
3291: BUG FIXES:
3292:
3293: * Fix "forward name lookup failed" errors on AIX 4.3.3. (John
3294: L. Allen, Martin Pool)
3295:
3296: * Generate each file's rolling-checksum data as we send it, not
3297: in a separate (memory-eating) pass before hand. This prevents
3298: timeout errors on really large files. (Stefan Nehlsen)
3299:
3300: * Fix compilation on Tru64. (Albert Chin, Zoong Pham)
3301:
3302: * Better handling of some client-server errors. (Martin Pool)
3303:
3304: * Fixed a crash that would occur when sending a list of files that
3305: contains a duplicate name (if it sorts to the end of the file
3306: list) and using --delete. (Wayne Davison)
3307:
3308: * Fixed the file-name duplicate-removal code when dealing with multiple
3309: dups in a row. (Wayne Davison)
3310:
3311: * Fixed a bug that caused rsync to lose the exit status of its child
3312: processes and sometimes return an exit code of 0 instead of showing
3313: an error. (David R. Staples, Dave Dykstra)
3314:
3315: * Fixed bug in --copy-unsafe-links that caused it to be completely
3316: broken. (Dave Dykstra)
3317:
3318: * Prevent infinite recursion in cleanup code under certain circumstances.
3319: (Sviatoslav Sviridov and Marc Espie)
3320:
3321: * Fixed a bug that prevented rsync from creating intervening directories
3322: when --relative-paths/-R is set. (Craig Barratt)
3323:
3324: * Prevent "Connection reset by peer" messages from Cygwin. (Randy O'Meara)
3325:
3326: INTERNAL:
3327:

3332:
3333: * More test cases. (Martin Pool)

3338: (Jos Backus)
3339:
3340: * Updated config.guess and config.sub to latest versions; this
3341: means rsync should build on more platforms. (Paul Green)

3348: ENHANCEMENTS:
3349:
3350: * With --progress, when a transfer is complete show the time taken;
3351: otherwise show expected time to complete. (Cameron Simpson)
3352:
3353: * Make "make install-strip" works properly, and "make install"
3354: accepts a DESTDIR variable for help in building binary packages.
3355: (Peter Breitenlohner, Greg Louis)
3356:
3357: * If configured with --enable-maintainer-mode, then on receipt of
3358: a fatal signal rsync will try to open an xterm running gdb,
3359: similarly to Samba's "panic action" or GNOME's bug-buddy.
3360: (Martin Pool)
3361:
3362:
3363: BUG FIXES:
3364:
3365: * Fix situation where failure to fork (e.g. because out of process
3366: slots) would cause rsync to kill all processes owned by the
3367: current user. Yes, really! (Paul Haas, Martin Pool)
3368:
3369: * Fix test suite on Solaris. (Jos Backus, Martin Pool)

3372: Pool.)
3373:

3375: for remote connections. (Martin Pool, Frank Schulz)
3376:
3377: * Work around bug in Mac OS X mkdir(2), which cannot handle
3378: trailing slashes.

3392: Tridgell) (CVE CAN-2002-0059)
3393:
3394: ENHANCEMENTS:
3395:
3396: * Merge in changes from zlib 1.1.3 to zlib 1.1.4. (Jos Backus)
3397: (Note that rsync still uses a custom version of zlib; you can
3398: not just link against a system library. See zlib/README.rsync)

3407: SECURITY FIXES:
3408:
3409: * Make sure that supplementary groups are removed from a server
3410: process after changing uid and gid. (Ethan Benson) (Debian bug
3411: #132272, CVE CAN-2002-0080)
3412:
3413: BUG FIXES:
3414:
3415: * Fix zlib double-free bug. (Owen Taylor, Mark J Cox) (CVE
3416: CAN-2002-0059)
3417:
3418: * Fixed problem that in many cases caused the error message
3419: unexpected read size of 0 in map_ptr
3420: and resulted in the wrong data being copied.
3421:
3422: * Fixed compilation errors on some systems caused by the use of
3423: "unsigned int64" in rsync.h.
3424:
3425: * Fixed problem on systems such as Sunos4 that do not support realloc
3426: on a NULL pointer; error was "out of memory in flist_expand".
3427:
3428: * Fix for rsync server processes hanging around after the client
3429: unexpectedly disconnects. (Colin Walters) (Debian bug #128632)
3430:
3431: * Cope with BSD systems on which mkdir() will not accept a trailing
3432: slash.
3433:
3434: ENHANCEMENTS:
3435:
3436: * Merge in changes from zlib 1.1.2 to zlib 1.1.3. (Note that
3437: rsync still uses a custom version of zlib; you can not just link
3438: against a system library. See zlib/README.rsync)
3439:
3440: * Command to initiate connections is only shown with -vv, rather
3441: than -v as in 2.5.2. Output from plain -v is more similar to
3442: what was historically used so as not to break scripts that try
3443: to parse the output.
3444:
3445: * Added --no-whole-file and --no-blocking-io options (Dave Dykstra)
3446:
3447: * Made the --write-batch and --read-batch options actually work
3448: and added documentation in the man page (Jos Backus)
3449:
3450: * If the daemon is unable to fork a child to accept a connection,
3451: print an error message. (Colin Walters)

3458: SECURITY FIXES:
3459:
3460: * Signedness security patch from Sebastian Krahmer
3461: <krahmer@suse.de> -- in some cases we were not sufficiently
3462: careful about reading integers from the network.
3463:
3464: BUG FIXES:
3465:
3466: * Fix possible string mangling in log files.
3467:
3468: * Fix for setting local address of outgoing sockets.
3469:
3470: * Better handling of hardlinks and devices on platforms with
3471: 64-bit dev_t or ino_t.
3472:
3473: * Name resolution on machines supporting IPv6 is improved.
3474:
3475: * Fix for device nodes. (dann frazier) (Debian #129135)
3476:
3477: ENHANCEMENTS:
3478:
3479: * With -v, rsync now shows the command used to initiate an ssh/rsh
3480: connection.
3481:
3482: * --statistics now shows memory heap usage on platforms that
3483: support mallinfo().
3484:
3485: * "The Ted T'so school of program optimization": make progress
3486: visible and people will think it's faster. (With --progress,
3487: rsync will show you how many files it has seen as it builds the
3488: file_list, giving some indication that it has not hung.)
3489:
3490: * Improvements to batch mode support. This is still experimental
3491: but testing would be welcome. (Jos Backus)
3492:
3493: * New --ignore-existing option, patch previously distributed with
3494: Vipul's Razor. (Debian #124286)

3504: Mackerras)

3524: multiple of bytes/s) and estimated time to completion. (Rik
3525: Faith)
3526:
3527: * --no-detach option, required to run as a W32 service and also
3528: useful when running on Unix under daemontools, AIX's SRC, or a
3529: debugger. (Max Bowsher, Jos Backus)
3530:
3531: * Clearer error messages for some conditions.

3538: ANNOUNCEMENTS
3539:
3540: * Martin Pool <mbp@samba.org> is now a co-maintainer.
3541:
3542: NEW FEATURES
3543:
3544: * Support for LSB-compliant packaging <http://www.linuxbase.org/>
3545:
3546: * Shell wildcards are allowed in "auth users" lines.
3547:
3548: * Merged UNC rsync+ patch to support creation of standalone patch
3549: sets. By Bert J. Dempsey and Debra Weiss, updated by Jos
3550: Backus. <http://www.ils.unc.edu/i2dsi/unc_rsync+.html>
3551:
3552: * IPv6 support based on a patch from KAME.net, on systems
3553: including modern versions of Linux, Solaris, and HP-UX. Also
3554: includes IPv6 compatibility functions for old OSs by the
3555: Internet Software Consortium, Paul Vixie, the OpenSSH
3556: portability project, and OpenBSD.
3557:
3558: ENHANCEMENTS
3559:
3560: * Include/exclude cluestick: with -vv, print out whether files are
3561: included or excluded and why.
3562:
3563: * Many error messages have more friendly explanations and more
3564: details.
3565:
3566: * Manual page improvements plus scanty protocol documentation.
3567:
3568: * When running as --daemon in the background and using a "log
3569: file" rsyncd.conf directive, close the log file every time it is
3570: open when going to sleep on the socket. This allows the log
3571: file to get cleaned out by another process.
3572:
3573: * Change to using libpopt rather than getopt for processing
3574: options. This makes the code cleaner and the behaviour more
3575: consistent across platforms. popt is included and built if not
3576: installed on the platform.
3577:
3578: * More details in --version, including note about whether 64-bit
3579: files, symlinks and hardlinks are supported.
3580:
3581: * MD4 code may use less CPU cycles.
3582:
3583: * Use mkstemp on systems where it is secure. If we use mktemp,
3584: explain that we do it in a secure way.
3585:
3586: * --whole-file is the default when source and target are on the
3587: local machine.
3588:
3589: BUG FIXES:

3592:
3593: * Attempt to fix Large File Summit support on AIX.
3594:
3595: * Attempt to fix error handling lockup bug.
3596:
3597: * Give a non-0 exit code if *any* of the files we have been asked
3598: to transfer fail to transfer.
3599:
3600: * For log messages containing ridiculously long strings that might
3601: overflow a buffer rsync no longer aborts, but rather prints an
3602: ellipsis at the end of the string. (Patch from Ed Santiago.)
3603:
3604: PLATFORMS:
3605:
3606: * Improved support for UNICOS (tested on Cray T3E and Cray SV1)
3607:
3608: * autoconf2.52 (or later) is now required to rebuild the autoconf
3609: scripts. It is not required to simply build rsync.
