    1: NEWS for rsync 3.0.8 (26 Mar 2011)
    2: Protocol: 30 (unchanged)
    3: Changes since 3.0.7:
    4: 
    5:   BUG FIXES:
    6: 
    7:     - Fixed two buffer-overflow issues: one where a directory path that is
    8:       exactly MAXPATHLEN was not handled correctly, and one handling a
    9:       --backup-dir that is extra extra large.
   10: 
   11:     - Fixed a data-corruption issue when preserving hard-links without
   12:       preserving file ownership, and doing deletions either before or during
   13:       the transfer (CVE-2011-1097).  This fixes some assert errors in the
   14:       hard-linking code, and some potential failed checksums (via -c) that
   15:       should have matched.
   16: 
   17:     - Fixed a potential crash when an rsync daemon has a filter/exclude list
   18:       and the transfer is using ACLs or xattrs.
   19: 
   20:     - Fixed a hang if a really large file is being processed by an rsync that
   21:       can't handle 64-bit numbers.  Rsync will now complain about the file
   22:       being too big and skip it.
   23: 
   24:     - For devices and special files, we now avoid gathering useless ACL and/or
   25:       xattr information for files that aren't being copied.  (The un-copied
   26:       files are still put into the file list, but there's no need to gather
   27:       data that is not going to be used.)  This ensures that if the user uses
   28:       --no-D, that rsync can't possibly complain about being unable to gather
   29:       extended information from special files that are in the file list (but
   30:       not in the transfer).
   31: 
   32:     - Properly handle requesting remote filenames that start with a dash.  This
   33:       avoids a potential error where a filename could be interpreted as a
   34:       (usually invalid) option.
   35: 
   36:     - Fixed a bug in the comparing of upper-case letters in file suffixes for
   37:       --skip-compress.
   38: 
   39:     - If an rsync daemon has a module configured without a path setting, rsync
   40:       will now disallow access to that module.
   41: 
   42:     - If the destination arg is an empty string, it will be treated as a
   43:       reference to the current directory (as 2.x used to do).
   44: 
   45:     - If rsync was compiled with a newer time-setting function (such as
   46:       lutimes), rsync will fall-back to an older function (such as utimes) on a
   47:       system where the newer function is not around.  This helps to make the
   48:       rsync binary more portable in mixed-OS-release situations.
   49: 
   50:     - Fixed a batch-file writing bug that would not write out the full set of
   51:       compatibility flags that the transfer was using.  This fixes a potential
   52:       protocol problem for a batch file that contains a sender-side I/O error:
   53:       it would have been sent in a way that the batch-reader wasn't expecting.
   54: 
   55:     - Some improvements to the hard-linking code to ensure that device-number
   56:       hashing is working right, and to supply more information if the hard-link
   57:       code fails.
   58: 
   59:     - The --inplace code was improved to not search for an impossible checksum
   60:       position.  The quadruple-verbose chunk[N] message will now mention when
   61:       an inplace chunk was handled by a seek rather than a read+write.
   62: 
   63:     - Improved ACL mask handling, e.g. for Solaris.
   64: 
   65:     - Fixed a bug that prevented --numeric-ids from disabling the translation
   66:       of user/group IDs for ACLs.
   67: 
   68:     - Fixed an issue where an xattr and/or ACL transfer that used an alt-dest
   69:       option (e.g. --link-dest) could output an error trying to itemize the
   70:       changes against the alt-dest directory's xattr/ACL info but was instead
   71:       trying to access the not-yet-existing new destination directory.
   72: 
   73:     - Improved xattr system-error messages to mention the full path to the
   74:       file.
   75: 
   76:     - The --link-dest checking for identical symlinks now avoids considering
   77:       attribute differences that cannot be changed on the receiver.
   78: 
   79:     - Avoid trying to read/write xattrs on certain file types for certain OSes.
   80:       Improved configure to set NO_SYMLINK_XATTRS, NO_DEVICE_XATTRS, and/or
   81:       NO_SPECIAL_XATTRS defines in config.h.
   82: 
   83:     - Improved the unsafe-symlink errors messages.
   84: 
   85:     - Fixed a bug setting xattrs on new files that aren't user writable.
   86: 
   87:     - Avoid re-setting xattrs on a hard-linked file w/the same xattrs.
   88: 
   89:     - Fixed a bug with --fake-super when copying files and dirs that aren't
   90:       user writable.
   91: 
   92:     - Fixed a bug where a sparse file could have its last sparse block turned
   93:       into a real block when rsync sets the file size (requires ftruncate).
   94: 
   95:     - If a temp-file name is too long, rsync now avoids truncating the name in
   96:       the middle of adjacent high-bit characters.  This prevents a potential
   97:       filename error if the filesystem doesn't allow a name to contain an
   98:       invalid multi-byte sequence.
   99: 
  100:     - If a muli-protocol socket connection fails (i.e., when contacting a
  101:       daemon), we now report all the failures, not just the last one.  This
  102:       avoids losing a relevant error (e.g. an IPv4 connection-refused error)
  103:       that happened before the final error (e.g. an IPv6 protocol-not-supported
  104:       error).
  105: 
  106:     - Generate a transfer error if we try to call chown with a -1 for a uid or
  107:       a gid (which is not settable).
  108: 
  109:     - Fixed the working of --force when used with --one-file-system.
  110: 
  111:     - Fix the popt arg parsing so that an option that doesn't take an arg will
  112:       reject an attempt to supply one (can configure --with-included-popt if
  113:       your system's popt library doesn't yet have this fix).
  114: 
  115:     - A couple minor option tweaks to the support/rrsync script, and also some
  116:       regex changes that make vim highlighting happier.
  117: 
  118:     - Fixed some issues in the support/mnt-excl script.
  119: 
  120:     - Various manpage improvements.
  121: 
  122:   ENHANCEMENTS:
  123: 
  124:     - Added ".hg/" to the default cvs excludes (see -C & --cvs-exclude).
  125: 
  126:   DEVELOPER RELATED:
  127: 
  128:     - Use lchmod() whenever it is available (not just on symlinks).
  129: 
  130:     - A couple fixes to the socketpair_tcp() routine.
  131: 
  132:     - Updated the helper scripts in the packaging subdirectory.
  133: 
  134:     - Renamed configure.in to configure.ac.
  135: 
  136:     - Fixed configure's checking for iconv routines for newer OS X versions.
  137: 
  138:     - Fixed the testsuite/xattrs.test script on OS X.

  141: NEWS for rsync 3.0.7 (31 Dec 2009)
  142: Protocol: 30 (unchanged)
  143: Changes since 3.0.6:
  144: 
  145:   BUG FIXES:
  146: 
  147:     - Fixed a bogus free when using --xattrs with --backup.
  148: 
  149:     - Avoid an error when --dry-run  was trying to stat a prior hard-link file
  150:       that hasn't really been created.
  151: 
  152:     - Fixed a problem with --compress (-z) where the receiving side could
  153:       return the error "inflate (token) returned -5".
  154: 
  155:     - Fixed a bug where --delete-during could delete in a directory before it
  156:       noticed that the sending side sent an I/O error for that directory (both
  157:       sides of the transfer must be at least 3.0.7).
  158: 
  159:     - Improved --skip-compress's error handling of bad character-sets and got
  160:       rid of a lingering debug fprintf().
  161: 
  162:     - Fixed the daemon's conveyance of io_error value from the sender.
  163: 
  164:     - An rsync daemon use seteuid() (when available) if it used setuid().
  165: 
  166:     - Get the permissions right on a --fake-super transferred directory that
  167:       needs more owner permissions to emulate root behavior.
  168: 
  169:     - An absolute-path filter rule (i.e. with a '/' modifier) no longer loses
  170:       its modifier when sending the filter rules to the remote rsync.
  171: 
  172:     - Improved the "--delete does not work without -r or -d" message.
  173: 
  174:     - Improved rsync's handling of --timeout to avoid a weird timeout case
  175:       where the sender could timeout even though it has recently written data
  176:       to the socket (but hasn't read data recently, due to the writing).
  177: 
  178:     - Some misc manpage improvements.
  179: 
  180:     - Fixed the chmod-temp-dir testsuite on a system without /var/tmp.
  181: 
  182:     - Make sure that a timeout specified in the daemon's config is used as a
  183:       maximum timeout value when the user also specifies a timeout.
  184: 
  185:     - Improved the error-exit reporting when rsync gets an error trying to
  186:       cleanup after an error:  the initial error is reported.
  187: 
  188:     - Improved configure's detection of IPv6 for solaris and cygwin.
  189: 
  190:     - The AIX sysacls routines will now return ENOSYS if ENOTSUP is missing.
  191: 
  192:     - Made our (only used if missing) getaddrinfo() routine use inet_pton()
  193:       (which we also provide) instead of inet_aton().
  194: 
  195:     - The exit-related debug messages now mention the program's role so it is
  196:       clear who output what message.
  197: 
  198:   DEVELOPER RELATED:
  199: 
  200:     - Got rid of type-punned compiler warnings output by newer gcc versions.
  201: 
  202:     - The Makefile now ensures that proto.h will be rebuilt if config.h changes.
  203: 
  204:     - The testsuite no longer uses "id -u", so it works better on solaris.

  207: NEWS for rsync 3.0.6 (8 May 2009)
  208: Protocol: 30 (unchanged)
  209: Changes since 3.0.5:
  210: 
  211:   BUG FIXES:
  212: 
  213:     - Fixed a --read-batch hang when rsync is reading a batch file that was
  214:       created from an incremental-recursion transfer.
  215: 
  216:     - Fixed the daemon's socket code to handle the simultaneous arrival of
  217:       multiple connections.
  218: 
  219:     - Fix --safe-links/--copy-unsafe-links to properly handle symlinks that
  220:       have consecutive slashes in the value.
  221: 
  222:     - Fixed the parsing of an [IPv6_LITERAL_ADDR] when a USER@ is prefixed.
  223: 
  224:     - The sender now skips a (bogus) symlink that has a 0-length value, which
  225:       avoids a transfer error in the receiver.
  226: 
  227:     - Fixed a case where the sender could die with a tag-0 error if there was
  228:       an I/O during the sending of the file list.
  229: 
  230:     - Fixed the rrsync script to avoid a server-side problem when -e is at the
  231:       start of the short options.
  232: 
  233:     - Fixed a problem where a vanished directory could turn into an exit code
  234:       23 instead of the proper exit code 24.
  235: 
  236:     - Fixed the --iconv conversion of symlinks when doing a local copy.
  237: 
  238:     - Fixed a problem where --one-file-system was not stopping deletions on the
  239:       receiving side when a mount-point directory did not match a directory in
  240:       the transfer.
  241: 
  242:     - Fixed the dropping of an ACL mask when no named ACL values were present.
  243: 
  244:     - Fixed an ACL/xattr corruption issue where the --backup option could cause
  245:       rsync to associate the wrong ACL/xattr information with received files.
  246: 
  247:     - Fixed the use of --xattrs with --only-write-batch.
  248: 
  249:     - Fixed the use of --dry-run with --read-batch.
  250: 
  251:     - Fixed configure's erroneous use of target.
  252: 
  253:     - Fixed configure's --disable-debug option.
  254: 
  255:     - Fixed a run-time issue for systems that can't find iconv_open() by adding
  256:       the --disable-iconv-open configure option.
  257: 
  258:     - Complain and die if the user tries to combine --remove-source-files (or
  259:       the deprecated --remove-sent-files) with --read-batch.
  260: 
  261:     - Fixed an failure transferring special files from Solaris to Linux.
  262: 
  263: 
  264: NEWS for rsync 3.0.5 (28 Dec 2008)
  265: Protocol: 30 (unchanged)
  266: Changes since 3.0.4:
  267: 
  268:   BUG FIXES:
  269: 
  270:     - Initialize xattr data in a couple spots in the hlink code, which avoids a
  271:       crash when the xattr pointer's memory happens to start out non-zero.
  272:       Also fixed the itemizing of an alt-dest file's xattrs when hard-linking.
  273: 
  274:     - Don't send a bogus "-" option to an older server if there were no short
  275:       options specified.
  276: 
  277:     - Fixed skipping of unneeded updates in a batch file when incremental
  278:       recursion is active.  Added a test for this.  Made batch-mode handle
  279:       "redo" files properly (and without hanging).
  280: 
  281:     - Fix the %P logfile escape when the daemon logs from inside a chroot.
  282: 
  283:     - Fixed the use of -s (--protect-args) when used with a remote source or
  284:       destination that had an empty path (e.g. "host:").  Also fixed a problem
  285:       when -s was used when accessing a daemon via a remote-shell.
  286: 
  287:     - Fixed the use of a dot-dir path (e.g. foo/./bar) inside a --files-from
  288:       file when the root of the transfer isn't the current directory.
  289: 
  290:     - Fixed a bug with "-K --delete" removing symlinks to directories when
  291:       incremental recursion is active.
  292: 
  293:     - Fixed a hard to trigger hang when using --remove-source-files.
  294: 
  295:     - Got rid of an annoying delay when accessing a daemon via a remote-shell.
  296: 
  297:     - Properly ignore (superfluous) source args on a --read-batch command.
  298: 
  299:     - Improved the manpage's description of the '*' wildcard to remove the
  300:       confusing "non-empty" qualifier.
  301: 
  302:     - Fixed reverse lookups in the compatibility-library version of
  303:       getnameinfo().
  304: 
  305:     - Fixed a bug when using --sparse on a sparse file that has over 2GB of
  306:       consecutive sparse data.
  307: 
  308:     - Avoid a hang when using at least 3 --verbose options on a transfer with a
  309:       client sender (which includes local copying).
  310: 
  311:     - Fixed a problem with --delete-delay reporting an error when it was ready
  312:       to remove a directory that was now gone.
  313: 
  314:     - Got rid of a bunch of "warn_unused_result" compiler warnings.
  315: 
  316:     - If an ftruncate() on a received file fails, it now causes a partial-
  317:       transfer warning.
  318: 
  319:     - Allow a path with a leading "//" to be preserved (CYGWIN only).
  320: 
  321:   ENHANCEMENTS:
  322: 
  323:     - Made the support/atomic-rsync script able to perform a fully atomic
  324:       update of the copied hierarchy when the destination is setup using a
  325:       particular symlink idiom.
  326: 
  327: 
  328: NEWS for rsync 3.0.4 (6 Sep 2008)
  329: Protocol: 30 (unchanged)
  330: Changes since 3.0.3:
  331: 
  332:   BUG FIXES:
  333: 
  334:     - Fixed a bug in the hard-linking code where it would sometimes try to
  335:       allocate 0 bytes of memory (which fails on some OSes, such as AIX).
  336: 
  337:     - Fixed the hard-linking of files from a device that has a device number
  338:       of 0 (which seems to be a common device number on NetBSD).
  339: 
  340:     - Fixed the handling of a --partial-dir that cannot be created.  This
  341:       particularly impacts the --delay-updates option (since the files cannot
  342:       be delayed without a partial-dir), and was potentially destructive if
  343:       the --remove-source-files was also specified.
  344: 
  345:     - Fixed a couple issues in the --fake-super handling of xattrs when the
  346:       destination files have root-level attributes (e.g. selinux values) that
  347:       a non-root copy can't affect.
  348: 
  349:     - Improved the keep-alive check in the generator to fire consistently in
  350:       incremental-recursion mode when --timeout is enabled.
  351: 
  352:     - The --iconv option now converts the content of a symlink too, instead
  353:       of leaving it in the wrong character-set (requires 3.0.4 on both sides
  354:       of the transfer).
  355: 
  356:     - When using --iconv, if a filename fails to convert on the receiving side,
  357:       this no longer makes deletions in the root-dir of the transfer fail
  358:       silently (the user now gets a warning about deletions being disabled
  359:       due to IO error as long as --ignore-errors was not specified).
  360: 
  361:     - When using --iconv, if a server-side receiver can't convert a filename,
  362:       the error message sent back to the client no longer mangles the name
  363:       with the wrong charset conversion.
  364: 
  365:     - Fixed a potential alignment issue in the IRIX ACL code when allocating
  366:       the initial "struct acl" object.  Also, cast mallocs to avoid warnings.
  367: 
  368:     - Changed some errors that were going to stdout to go to stderr.
  369: 
  370:     - Made human_num() and human_dnum() able to output a negative number
  371:       (rather than outputting a cryptic string of punctuation).
  372: 
  373:   ENHANCEMENTS:
  374: 
  375:     - Rsync will avoid sending an -e option to the server if an older protocol
  376:       is requested (and thus the option would not be useful).  This lets the
  377:       user specify the --protocol=29 option to access an overly-restrictive
  378:       server that is rejecting the protocol-30 use of -e to the server.
  379: 
  380:     - Improved the message output for an RERR_PARTIAL exit.
  381: 
  382:   DEVELOPER RELATED:
  383: 
  384:     - The Makefile will not halt for just a timestamp change on the Makefile
  385:       or the configure files, only for actual changes in content.
  386: 
  387:     - Changed some commands in the testsuite's xattrs.test that called "rsync"
  388:       instead of "$RSYNC".
  389: 
  390:     - Enhanced the release scripts to be able to handle a branch release and
  391:       to do even more consistency checks on the files.

  403:     - Fixed a crash bug in the hard-link code.
  404: 
  405:     - Fixed the sending of xattr directory information when the code finds a
  406:       --link-dest or --copy-dest directory with unchanged xattrs -- the
  407:       destination directory now gets these unchanged xattrs properly applied.
  408: 
  409:     - Fixed an xattr-sending glitch that could cause an "Internal abbrev"
  410:       error.
  411: 
  412:     - Fixed the combination of --xattrs and --backup.
  413: 
  414:     - The generator no longer allows a '.' dir to be excluded by a daemon-
  415:       exclude rule.
  416: 
  417:     - Fixed deletion handling when copying a single, empty directory (with no
  418:       files) to a differently named, non-existent directory.
  419: 
  420:     - Fixed the conversion of spaces into dashes in the %M log escape.
  421: 
  422:     - Fixed several places in the code that were not returning the right
  423:       errno when a function failed.
  424: 
  425:     - Fixed the backing up of a device or special file into a backup dir.
  426: 
  427:     - Moved the setting of the socket options prior to the connect().
  428: 
  429:     - If rsync exits in the middle of a --progress output, it now outputs a
  430:       newline to help prevent the progress line from being overwritten.
  431: 
  432:     - Fixed a problem with how a destination path with a trailing slash or
  433:       a trailing dot-dir was compared against the daemon excludes.
  434: 
  435:     - Fixed the sending of large (size > 16GB) files when talking to an older
  436:       rsync (protocols < 30):  we now use a compatible block size limit.
  437: 
  438:     - If a file's length is so huge that we overflow a checksum buffer count
  439:       (i.e. several hundred TB), warn the user and avoid sending an invalid
  440:       checksum struct over the wire.
  441: 
  442:     - If a source arg is excluded, --relative no longer adds the excluded
  443:       arg's implied dirs to the transfer.  This fix also made the exclude
  444:       check happen in the better place in the sending code.
  445: 
  446:     - Use the overflow_exit() function for overflows, not out_of_memory().
  447: 
  448:     - Improved the code to better handle a system that has only 32-bit file
  449:       offsets.
  450: 
  451:   ENHANCEMENTS:
  452: 
  453:     - The rsyncd.conf manpage now consistently refers to the parameters in
  454:       the daemon config file as "parameters".
  455: 
  456:     - The description of the --inplace option was improved.
  457: 
  458:   EXTRAS:
  459: 
  460:     - Added a new script in the support directory, deny-rsync, which allows
  461:       an admin to (temporarily) replace the rsync command with a script that
  462:       sends an error message to the remote client via the rsync protocol.
  463: 
  464:   DEVELOPER RELATED:
  465: 
  466:     - Fixed a testcase failure if the tests are run as root and made some
  467:       compatibility improvements.
  468: 
  469:     - Improved the daemon tests, including checking module comments, the
  470:       listing of files, and the ensuring that daemon excludes can't affect
  471:       a dot-dir arg.
  472: 
  473:     - Improved some build rules for those that build in a separate directory
  474:       from the source, including better install rules for the man pages, and
  475:       the fixing of a proto.h-tstamp rule that could make the binaries get
  476:       rebuild without cause.
  477: 
  478:     - Improved the testsuite to work around a problem with some utilities
  479:       (e.g. cp -p & touch -r) rounding sub-second timestamps.
  480: 
  481:     - Ensure that the early patches don't cause any generated-file hunks to
  482:       bleed-over into patches that follow.

  505: NEWS for rsync 3.0.1 (3 Apr 2008)
  506: Protocol: 30 (unchanged)
  507: Changes since 3.0.0:
  508: 
  509:   NOTABLE CHANGES IN BEHAVIOR:
  510: 
  511:     - Added the 'c'-flag to the itemizing of non-regular files so that the
  512:       itemized output doesn't get hidden if there were no attribute changes,
  513:       and also so that the itemizing of a --copy-links run will distinguish
  514:       between copying an identical non-regular file and the creation of a
  515:       revised version with a new value (e.g. a changed symlink referent, a
  516:       new device number, etc.).
  517: 
  518:   BUG FIXES:
  519: 
  520:     - Fixed a crash bug when a single-use rsync daemon (via remote shell) was
  521:       run without specifying a --config=FILE option.
  522: 
  523:     - Fixed a crash when backing up a directory that has a default ACL.
  524: 
  525:     - Fixed a bug in the handling of xattr values that could cause rsync to
  526:       not think that a file's extended attributes are up-to-date.
  527: 
  528:     - Fixed the working of --fake-super with --link-dest and --xattrs.
  529: 
  530:     - Fixed a hang when combining --dry-run with --remove-source-files.
  531: 
  532:     - Fixed a bug with --iconv's handling of files that cannot be converted:
  533:       a failed name can no longer cause a transfer failure.
  534: 
  535:     - Fixed the building of the rounding.h file on systems that need custom
  536:       CPPFLAGS to be used.  Also improved the error reporting if the building
  537:       of rounding.h fails.
  538: 
  539:     - Fixed the use of the --protect-args (-s) option when talking to a daemon.
  540: 
  541:     - Fixed the --ignore-existing option's protection of files on the receiver
  542:       that are non-regular files on the sender (e.g. if a symlink or a dir on
  543:       the sender is trying to replace a file on the receiver).  The reverse
  544:       protection (protecting a dir/symlink/device from being replaced by a
  545:       file) was already working.
  546: 
  547:     - Fixed an assert failure if --hard-links is combined with an option that
  548:       can skip a file in a set of hard-linked files (i.e. --ignore-existing,
  549:       --append, etc.), without skipping all the files in the set.
  550: 
  551:     - Avoid setting the modify time on a directory that already has the right
  552:       modify time set.  This avoids tweaking the dir's ctime.
  553: 
  554:     - Improved the daemon-exclude handling to do a better job of applying the
  555:       exclude rules to path entries.  It also sends the user an error just as
  556:       if the files were actually missing (instead of silently ignoring the
  557:       user's args), and avoids sending the user the filter-action messages
  558:       for these non-user-initiated rules.
  559: 
  560:     - Fixed some glitches with the dry-run code's missing-directory
  561:       handling, including a problem when combined with --fuzzy.
  562: 
  563:     - Fixed some glitches with the skipped-directory handling.
  564: 
  565:     - Fixed the 'T'-flag itemizing of symlinks when --time isn't preserved.
  566: 
  567:     - Fixed a glitch in the itemizing of permissions with the -E option.
  568: 
  569:     - The --append option's restricting of transfers to those that add data no
  570:       longer prevents the updating of non-content changes to otherwise up-to-
  571:       date files (i.e. those with the same content but differing permissions,
  572:       ownership, xattrs, etc.).
  573: 
  574:     - Don't allow --fake-super to be specified with -XX (double --xattrs)
  575:       because the options conflict.  If a daemon has "fake super" enabled,
  576:       it automatically downgrades a -XX request to -X.
  577: 
  578:     - Fixed a couple bugs in the parsing of daemon-config excludes that could
  579:       make a floating exclude rule get treated as matching an absolute path.
  580: 
  581:     - A daemon doesn't try to auto-refuse the "iconv" option if iconv-support
  582:       wasn't compiled in to the daemon (avoiding a warning in the logs).
  583: 
  584:     - Fixed the inclusion of per-dir merge files from implied dirs.
  585: 
  586:     - Fixed the support/rrsync script to work with the latest options that
  587:       rsync sends (including its flag-specifying use of -e to the server).
  588: 
  589:   ENHANCEMENTS:
  590: 
  591:     - Added the --old-dirs (--old-d) option to make it easier for a user to
  592:       ask for file-listings with older rsync versions (this is easier than
  593:       having to type "-r --exclude='/*/*'" manually).
  594: 
  595:     - When getting an error while asking an older rsync daemon for a file
  596:       listing, rsync will try to notice if the error is a rejection of the
  597:       --dirs (-d) option and let the user know how to work around the issue.
  598: 
  599:     - Added a few more --no-OPTION overrides.
  600: 
  601:     - Improved the documentation of the --append option.
  602: 
  603:     - Improved the documentation of the filter/exclude/include daemon
  604:       parameters.
  605: 
  606:   INTERNAL:
  607: 
  608:     - Fixed a couple minor bugs in the included popt library (ones which I
  609:       sent to the official popt project for inclusion in the 1.14 release).
  610: 
  611:     - Fixed a stat() call that should have been do_stat() so that the proper
  612:       normal/64-bit stat() function gets called.  (Was in an area that should
  613:       not have caused problems, though.)
  614: 
  615:     - Changed the file-glob code to do a directory scan without using the
  616:       "glob" and "glob.h".  This lets us do the globbing with less memory
  617:       churn, and also avoid adding daemon-excluded items to the returned
  618:       args.
  619: 
  620:   DEVELOPER RELATED:
  621: 
  622:     - The configure script tries to get the user's compiler to not warn about
  623:       unused function parameters if the build is not including one or more of
  624:       the ACL/xattrs/iconv features.
  625: 
  626:     - The configure script now has better checks for figuring out if the
  627:       included popt code should be used or not.
  628: 
  629:     - Fixed two testsuite glitches: avoid a failure if someone's "cd" command
  630:       outputs the current directory when cd-ing to a relative path, and made
  631:       the itemized test query how rsync was built to determine if it should
  632:       expect hard-linked symlinks or not.
  633: 
  634:     - Updated the testsuite to verify that various bug fixes remain fixed.
  635: 
  636:     - The RPM spec file was updated to have: (1) comments for how to use the
  637:       rsync-patch tar file, and (2) an /etc/xinetd.d/rsync file.
  638: 
  639:     - Updated the build scripts to work with a revised FTP directory
  640:       structure.

  643: NEWS for rsync 3.0.0 (1 Mar 2008)
  644: Protocol: 30 (changed)
  645: Changes since 2.6.9:
  646: 
  647:   NOTABLE CHANGES IN BEHAVIOR:
  648: 
  649:     - The handling of implied directories when using --relative has changed to
  650:       send them as directories (e.g. no implied dir is ever sent as a symlink).
  651:       This avoids unexpected behavior and should not adversely affect most
  652:       people.  If you're one of those rare individuals who relied upon having
  653:       an implied dir be duplicated as a symlink, you should specify the
  654:       transfer of the symlink and the transfer of the referent directory as
  655:       separate args.  (See also --keep-dirlinks and --no-implied-dirs.)
  656:       Also, exclude rules no longer have a partial effect on implied dirs.
  657: 
  658:     - Requesting a remote file-listing without specifying -r (--recursive) now
  659:       sends the -d (--dirs) option to the remote rsync rather than sending -r
  660:       along with an extra exclude of /*/*.  If the remote rsync does not
  661:       understand the -d option (i.e. it is 2.6.3 or older), you will need to
  662:       either turn off -d (--no-d), or specify  -r --exclude='/*/*'  manually.
  663: 
  664:     - In --dry-run mode, the last line of the verbose summary text is output
  665:       with a "(DRY RUN)" suffix to help remind you that no updates were made.
  666:       Similarly, --only-write-batch outputs "(BATCH ONLY)".
  667: 
  668:     - A writable rsync daemon with "use chroot" disabled now defaults to a
  669:       symlink-munging behavior designed to make symlinks safer while also
  670:       allowing absolute symlinks to be stored and retrieved.  This also has
  671:       the effect of making symlinks unusable while they're in the daemon's
  672:       hierarchy.  See the daemon's "munge symlinks" parameter for details.
  673: 
  674:     - Starting up an extra copy of an rsync daemon will not clobber the pidfile
  675:       for the running daemon -- if the pidfile exists, the new daemon will exit
  676:       with an error.  This means that your wrapper script that starts the rsync
  677:       daemon should be made to handle lock-breaking (if you want any automatic
  678:       breaking of locks to be done).
  679: 
  680:   BUG FIXES:
  681: 
  682:     - A daemon with "use chroot = no" and excluded items listed in the daemon
  683:       config file now properly checks an absolute-path arg specified for these
  684:       options:  --compare-dest, --link-dest, --copy-dest, --partial-dir,
  685:       --backup-dir, --temp-dir, and --files-from.
  686: 
  687:     - A daemon can now be told to disable all user- and group-name translation
  688:       on a per-module basis.  This avoids a potential problem with a writable
  689:       daemon module that has "use chroot" enabled -- if precautions weren't
  690:       taken, a user could try to add a missing library and get rsync to use
  691:       it.  This makes rsync safer by default, and more configurable when id-
  692:       translation is not desired.  See the daemon's "numeric ids" parameter
  693:       for full details.
  694: 
  695:     - A chroot daemon can now indicate which part of its path should affect the
  696:       chroot call, and which part should become an inside-chroot path for the
  697:       module.  This allows you to have outside-the-transfer paths (such as for
  698:       libraries) even when you enable chroot protection.  The idiom used in the
  699:       rsyncd.conf file is:  path = /chroot/dirs/./dirs/inside
  700: 
  701:     - If a file's data arrived successfully on the receiving side but the
  702:       rename of the temporary file to the destination file failed AND the
  703:       --remove-source-files (or the deprecated --remove-sent-files) option
  704:       was specified, rsync no longer erroneously removes the associated
  705:       source file.
  706: 
  707:     - Fixed the output of -ii when combined with one of the --*-dest options:
  708:       it now itemizes all the items, not just the changed ones.
  709: 
  710:     - Made the output of all file types consistent when using a --*-dest
  711:       option.  Prior versions would output too many creation events for
  712:       matching items.
  713: 
  714:     - The code that waits for a child pid now handles being interrupted by a
  715:       signal.  This fixes a problem with the pre-xfer exec function not being
  716:       able to get the exit status from the script.
  717: 
  718:     - A negated filter rule (i.e. with a '!' modifier) no longer loses the
  719:       negation when sending the filter rules to the remote rsync.
  720: 
  721:     - Fixed a problem with the --out-format (aka --log-format) option %f:  it
  722:       no longer outputs superfluous directory info for a non-daemon rsync.
  723: 
  724:     - Fixed a problem with -vv (double --verbose) and --stats when "pushing"
  725:       files (which includes local copies).  Version 2.6.9 would complete the
  726:       copy, but exit with an error when the receiver output its memory stats.
  727: 
  728:     - If --password-file is used on a non-daemon transfer, rsync now complains
  729:       and exits.  This should help users figure out that they can't use this
  730:       option to control a remote shell's password prompt.
  731: 
  732:     - Make sure that directory permissions of a newly-created destination
  733:       directory are handled right when --perms is left off.
  734: 
  735:     - The itemized output of a newly-created destination directory is now
  736:       output as a creation event, not a change event.
  737: 
  738:     - Improved --hard-link so that more corner cases are handled correctly
  739:       when combined with options such as --link-dest and/or --ignore-existing.
  740: 
  741:     - The --append option no longer updates a file that has the same size.
  742: 
  743:     - Fixed a bug when combining --backup and --backup-dir with --inplace:
  744:       any missing backup directories are now created.
  745: 
  746:     - Fixed a bug when using --backup and --inplace with --whole-file or
  747:       --read-batch: backup files are actually created now.
  748: 
  749:     - The daemon pidfile is checked and created sooner in the startup sequence.
  750: 
  751:     - If a daemon module's "path" value is not an absolute pathname, the code
  752:       now makes it absolute internally (making it work properly).
  753: 
  754:     - Ensure that a temporary file always has owner-write permission while we
  755:       are writing to it.  This avoids problems with some network filesystems
  756:       when transfering read-only files.
  757: 
  758:     - Any errors output about password-file reading no longer cause an error at
  759:       the end of the run about a partial transfer.
  760: 
  761:     - The --read-batch option for protocol 30 now ensures that several more
  762:       options are set correctly for the current batch file:  --iconv, --acls,
  763:       --xattrs, --inplace, --append, and --append-verify.
  764: 
  765:     - Using --only-write-batch to a daemon receiver now works properly (older
  766:       versions would update some files while writing the batch).
  767: 
  768:     - Avoid outputting a "file has vanished" message when the file is a broken
  769:       symlink and --copy-unsafe-links or --copy-dirlinks is used (the code
  770:       already handled this for --copy-links).
  771: 
  772:     - Fixed the combination of --only-write-batch and --dry-run.
  773: 
  774:     - Fixed rsync's ability to remove files that are not writable by the file's
  775:       owner when rsync is running as the same user.
  776: 
  777:     - When transferring large files, the sender's hashtable of checksums is
  778:       kept at a more reasonable state of fullness (no more than 80% full) so
  779:       that the scanning of the hashtable will not bog down as the number of
  780:       blocks increases.
  781: 
  782:   ENHANCEMENTS:
  783: 
  784:     - A new incremental-recursion algorithm is now used when rsync is talking
  785:       to another 3.x version.  This starts the transfer going more quickly
  786:       (before all the files have been found), and requires much less memory.
  787:       See the --recursive option in the manpage for some restrictions.
  788: 
  789:     - Lowered memory use in the non-incremental-recursion algorithm for typical
  790:       option values (usually saving from 21-29 bytes per file).
  791: 
  792:     - The default --delete algorithm is now --delete-during when talking to a
  793:       3.x rsync.  This is a faster scan than using --delete-before (which is
  794:       the default when talking to older rsync versions), and is compatible with
  795:       the new incremental recursion mode.
  796: 
  797:     - Rsync now allows multiple remote-source args to be specified rather than
  798:       having to rely on a special space-splitting side-effect of the remote-
  799:       shell.  Additional remote args must specify the same host or an empty one
  800:       (e.g. empty:  :file1  or  ::module/file2).  For example, this means that
  801:       local use of brace expansion now works:  rsync -av host:dir/{f1,f2} .
  802: 
  803:     - Added the --protect-args (-s) option, that tells rsync to send most of
  804:       the command-line args at the start of the transfer rather than as args
  805:       to the remote-shell command.  This protects them from space-splitting,
  806:       and only interprets basic wildcard special shell characters (*?[).
  807: 
  808:     - Added the --delete-delay option, which is a more efficient way to delete
  809:       files at the end of the transfer without needing a separate delete pass.
  810: 
  811:     - Added the --acls (-A) option to preserve Access Control Lists.  This is
  812:       an improved version of the prior patch that was available, and it even
  813:       supports OS X ACLs.  If you need to have backward compatibility with old,
  814:       ACL-patched versions of rsync, apply the acls.diff file from the patches
  815:       dir.
  816: 
  817:     - Added the --xattrs (-X) option to preserve extended attributes.  This is
  818:       an improved version of the prior patch that was available, and it even
  819:       supports OS X xattrs (which includes their resource fork data).  If you
  820:       need to have backward compatibility with old, xattr-patched versions of
  821:       rsync, apply the xattrs.diff file from the patches dir.
  822: 
  823:     - Added the --fake-super option that allows a non-super user to preserve
  824:       all attributes of a file by using a special extended-attribute idiom.
  825:       It even supports the storing of foreign ACL data on your backup server.
  826:       There is also an analogous "fake super" parameter for an rsync daemon.
  827: 
  828:     - Added the --iconv option, which allows rsync to convert filenames from
  829:       one character-set to another during the transfer.  The default is to
  830:       make this feature available as long as your system has iconv_open().
  831:       If compilation fails, specify --disable-iconv to configure, and then
  832:       rebuild.  If you want rsync to perform character-set conversions by
  833:       default, you can specify --enable-iconv=CONVERT_STRING with the default
  834:       value for the --iconv option that you wish to use.  For example,
  835:       "--enable-iconv=." is a good choice.  See the rsync manpage for an
  836:       explanation of the --iconv option's settings.
  837: 
  838:     - A new daemon config parameter, "charset", lets you control the character-
  839:       set that is used during an --iconv transfer to/from a daemon module.  You
  840:       can also set your daemon to refuse "no-iconv" if you want to force the
  841:       client to use an --iconv transfer (requiring an rsync 3.x client).
  842: 
  843:     - Added the --skip-compress=LIST option to override the default list of
  844:       file suffixes that will not be compressed when using --compress (-z).
  845: 
  846:     - The daemon's default for "dont compress" was extended to include:
  847: 	  *.7z *.mp[34] *.mov *.avi *.ogg *.jpg *.jpeg
  848:       The name-matching routine was also optimized to run more quickly.
  849: 
  850:     - The --max-delete option now outputs a warning if it skipped any file
  851:       deletions, including a count of how many deletions were skipped.  (Older
  852:       versions just silently stopped deleting things.)
  853: 
  854:     - You may specify --max-delete=0 to a 3.0.0 client to request that it warn
  855:       about extraneous files without deleting anything.  If you're not sure
  856:       what version the client is, you can use the less-obvious --max-delete=-1,
  857:       as both old and new versions will treat that as the same request (though
  858:       older versions don't warn).
  859: 
  860:     - The --hard-link option now uses less memory on both the sending and
  861:       receiving side for all protocol versions.  For protocol 30, the use of a
  862:       hashtable on the sending side allows us to more efficiently convey to the
  863:       receiver what files are linked together.  This reduces the amount of data
  864:       sent over the socket by a considerable margin (rather than adding more
  865:       data), and limits the in-memory storage of the device+inode information
  866:       to just the sending side for the new protocol 30, or to the receiving
  867:       side when speaking an older protocol (note that older rsync versions kept
  868:       the device+inode information on both sides).
  869: 
  870:     - The filter rules now support a perishable ("p") modifier that marks rules
  871:       that should not have an effect in a directory that is being deleted.  e.g.
  872:       -f '-p .svn/' would only affect "live" .svn directories.
  873: 
  874:     - Rsync checks all the alternate-destination args for validity (e.g.
  875:       --link-dest).  This lets the user know when they specified a directory
  876:       that does not exist.
  877: 
  878:     - If we get an ENOSYS error setting the time on a symlink, we don't
  879:       complain about it anymore (for those systems that even support the
  880:       setting of the modify-time on a symlink).
  881: 
  882:     - Protocol 30 now uses MD5 checksums instead of MD4.
  883: 
  884:     - Changed the --append option to not checksum the existing data in the
  885:       destination file, which speeds up file appending.
  886: 
  887:     - Added the --append-verify option, which works like the older --append
  888:       option (verifying the existing data in the destination file).  For
  889:       compatibility with older rsync versions, any use of --append that is
  890:       talking protocol 29 or older will revert to the --append-verify method.
  891: 
  892:     - Added the --contimeout=SECONDS option that lets the user specify a
  893:       connection timeout for rsync daemon access.
  894: 
  895:     - Documented and extended the support for the RSYNC_CONNECT_PROG variable
  896:       that can be used to enhance the client side of a daemon connection.
  897: 
  898:     - Improved the dashes and double-quotes in the nroff manpage output.
  899: 
  900:     - Rsync now supports a lot more --no-OPTION override options.
  901: 
  902:   INTERNAL:
  903: 
  904:     - The file-list sorting algorithm now uses a sort that keeps any same-
  905:       named items in the same order as they were specified.  This allows
  906:       rsync to always ensure that the first of the duplicates is the one
  907:       that will be included in the copy.  The new sort is also faster
  908:       than the glibc version of qsort() and mergesort().
  909: 
  910:     - Rsync now supports the transfer of 64-bit timestamps (time_t values).
  911: 
  912:     - Made the file-deletion code use a little less stack when recursing
  913:       through a directory hierarchy of extraneous files.
  914: 
  915:     - Fixed a build problem with older (2.x) versions of gcc.
  916: 
  917:     - Added some isType() functions that make dealing with signed characters
  918:       easier without forcing variables via casts.
  919: 
  920:     - Changed strcat/strcpy/sprintf function calls to use safer versions.
  921: 
  922:     - Upgraded the included popt version to 1.10.2 and improved its use of
  923:       string-handling functions.
  924: 
  925:     - Added missing prototypes for compatibility functions from the lib dir.
  926: 
  927:     - Configure determines if iconv() has a const arg, allowing us to avoid a
  928:       compiler warning.
  929: 
  930:     - Made the sending of some numbers more efficient for protocol 30.
  931: 
  932:     - Make sure that a daemon process doesn't mind if the client was weird and
  933:       omitted the --server option.
  934: 
  935:     - There are more internal logging categories available in protocol 30 than
  936:       the age-old FINFO and FERROR, including FERROR_XFER and FWARN.  These new
  937:       categories allow some errors and warnings to go to stderr without causing
  938:       an erroneous end-of-run warning about some files not being able to be
  939:       transferred.
  940: 
  941:     - Improved the use of "const" on pointers.
  942: 
  943:     - Improved J.W.'s pool_alloc routines to add a way of incrementally freeing
  944:       older sections of a pool's memory.
  945: 
  946:     - The getaddrinfo.c compatibility code in the "lib" dir was replaced with
  947:       some new code (derived from samba, derived from PostgreSQL) that has a
  948:       better license than the old code.
  949: 
  950:   DEVELOPER RELATED:
  951: 
  952:     - Rsync is now licensed under the GPLv3 or later.
  953: 
  954:     - Rsync is now being maintained in a "git" repository instead of CVS
  955:       (though the old CVS repository still exists for historical access).
  956:       Several maintenance scripts were updated to work with git.
  957: 
  958:     - Generated files are no longer committed into the source repository.  The
  959:       autoconf and autoheader commands are now automatically run during the
  960:       normal use of "configure" and "make".  The latest dev versions of all
  961:       generated files can also be copied from the samba.org web site (see the
  962:       prepare-source script's fetch option).
  963: 
  964:     - The "patches" directory of diff files is now built from branches in the
  965:       rsync git repository (branch patch/FOO creates file patches/FOO.diff).
  966:       This directory is now distributed in a separate separate tar file named
  967:       rsync-patches-VERSION.tar.gz instead of the main rsync-VERSION.tar.gz.
  968: 
  969:     - The proto.h file is now built using a simple perl script rather than a
  970:       complex awk script, which proved to be more widely compatible.
  971: 
  972:     - When running the tests, we now put our per-test temp dirs into a sub-
  973:       directory named testtmp (which is created, if missing).  This allows
  974:       someone to symlink the testtmp directory to another filesystem (which is
  975:       useful if the build dir's filesystem does not support ACLs and xattrs,
  976:       but another filesystem does).
  977: 
  978:     - Rsync now has a way of handling protocol-version changes during the
  979:       development of a new protocol version.  This causes any out-of-sync
  980:       versions to speak an older protocol rather than fail in a cryptic manner.
  981:       This addition makes it safer to deploy a pre-release version that may
  982:       interact with the public.  This new exchange of sub-version info does not
  983:       interfere with the {MIN,MAX}_PROTOCOL_VERSION checking algorithm (which
  984:       does not have enough range to allow the main protocol number to be
  985:       incremented for every minor tweak in that happens during development).
  986: 
  987:     - The csprotocol.txt file was updated to mention the daemon protocol change
  988:       in the 3.0.0 release.

  991: NEWS for rsync 2.6.9 (6 Nov 2006)
  992: Protocol: 29 (unchanged)
  993: Changes since 2.6.8:
  994: 
  995:   BUG FIXES:
  996: 
  997:     - If rsync is interrupted via a handled signal (such as SIGINT), it will
  998:       once again clean-up its temp file from the destination dir.
  999: 
 1000:     - Fixed an overzealous sanitizing bug in the handling of the --link-dest,
 1001:       --copy-dest, and --compare-dest options to a daemon without chroot: if
 1002:       the copy's destination dir is deeper than the top of the module's path,
 1003:       these options now accept a safe number of parent-dir (../) references
 1004:       (since these options are relative to the destination dir).  The old code
 1005:       incorrectly chopped off all "../" prefixes for these options, no matter
 1006:       how deep the destination directory was in the module's hierarchy.
 1007: 
 1008:     - Fixed a bug where a deferred info/error/log message could get sent
 1009:       directly to the sender instead of being handled by rwrite() in the
 1010:       generator.  This fixes an "unexpected tag 3" fatal error, and should
 1011:       also fix a potential problem where a deferred info/error message from
 1012:       the receiver might bypass the log file and get sent only to the client
 1013:       process.  (These problems could only affect an rsync daemon that was
 1014:       receiving files.)
 1015: 
 1016:     - Fixed a bug when --inplace was combined with a --*-dest option and we
 1017:       update a file's data using an alternate basis file.  The code now
 1018:       notices that it needs to copy the matching data from the basis file
 1019:       instead of (wrongly) assuming that it was already present in the file.
 1020: 
 1021:     - Fixed a bug where using --dry-run with a --*-dest option with a path
 1022:       relative to a directory that does not yet exist:  the affected option
 1023:       gets its proper path value so that the output of the dry-run is right.
 1024: 
 1025:     - Fixed a bug in the %f logfile escape when receiving files: the
 1026:       destination path is now included in the output (e.g. you can now tell
 1027:       when a user specifies a subdir inside a module).
 1028: 
 1029:     - If the receiving side fails to create a directory, it will now skip
 1030:       trying to update everything that is inside that directory.
 1031: 
 1032:     - If --link-dest is specified with --checksum but without --times, rsync
 1033:       will now allow a hard-link to be created to a matching link-dest file
 1034:       even when the file's modify-time doesn't match the server's file.
 1035: 
 1036:     - The daemon now calls more timezone-using functions prior to doing a
 1037:       chroot.  This should help some C libraries to generate proper timestamps
 1038:       from inside a chrooted daemon (and to not try to access /etc/timezone
 1039:       over and over again).
 1040: 
 1041:     - Fixed a bug in the handling of an absolute --partial-dir=ABS_PATH option:
 1042:       it now deletes an alternate basis file from the partial-dir that was used
 1043:       to successfully update a destination file.
 1044: 
 1045:     - Fixed a bug in the handling of --delete-excluded when using a per-dir
 1046:       merge file:  the merge file is now honored on the receiving side, and
 1047:       only its unqualified include/exclude commands are ignored (just as is
 1048:       done for global include/excludes).
 1049: 
 1050:     - Fixed a recent bug where --delete was not working when transferring from
 1051:       the root (/) of the filesystem with --relative enabled.
 1052: 
 1053:     - Fixed a recent bug where an --exclude='*' could affect the root (/) of
 1054:       the filesystem with --relative enabled.
 1055: 
 1056:     - When --inplace creates a file, it is now created with owner read/write
 1057:       permissions (0600) instead of no permissions at all.  This avoids a
 1058:       problem continuing a transfer that was interrupted (since --inplace
 1059:       will not update a file that has no write permissions).
 1060: 
 1061:     - If either --remove-source-files or --remove-sent-files is enabled and we
 1062:       are unable to remove the source file, rsync now outputs an error.
 1063: 
 1064:     - Fixed a bug in the daemon's "incoming chmod" rule:  newly-created
 1065:       directories no longer get the 'F' (file) rules applied to them.
 1066: 
 1067:     - Fixed an infinite loop bug when a filter rule was rejected due to being
 1068:       overly long.
 1069: 
 1070:     - When the server receives a --partial-dir option from the client, it no
 1071:       longer runs the client-side code that adds an assumed filter rule (since
 1072:       the client will be sending us the rules in the usual manner, and they
 1073:       may have chosen to override the auto-added rule).
 1074: 
 1075:   ENHANCEMENTS:
 1076: 
 1077:     - Added the --log-file=FILE and --log-file-format=FORMAT options.  These
 1078:       can be used to tell any rsync to output what it is doing to a log file.
 1079:       They work with a client rsync, a non-daemon server rsync (see the man
 1080:       page for instructions), and also allows the overriding of rsyncd.conf
 1081:       settings when starting a daemon.
 1082: 
 1083:     - The --log-format option was renamed to be --out-format to avoid confusing
 1084:       it with affecting the log-file output.  (The old option remains as an
 1085:       alias for the new to preserve backward compatibility.)
 1086: 
 1087:     - Made "log file" and "syslog facility" settable on a per-module basis in
 1088:       the daemon's config file.
 1089: 
 1090:     - Added the --remove-source-files option as a replacement for the (now
 1091:       deprecated) --remove-sent-files option.  This new option removes all
 1092:       non-dirs from the source directories, even if the file was already
 1093:       up-to-date.  This fixes a problem where interrupting an rsync that
 1094:       was using --remove-sent-files and restarting it could leave behind
 1095:       a file that the earlier rsync synchronized, but didn't get to remove.
 1096:       (The deprecated --remove-sent-files is still understood for now, and
 1097:       still behaves in the same way as before.)
 1098: 
 1099:     - Added the option --no-motd to suppress the message-of-the-day output
 1100:       from a daemon when doing a copy.  (See the manpage for a caveat.)
 1101: 
 1102:     - Added a new environment variable to the pre-/post-xfer exec commands (in
 1103:       the daemon's config file):  RSYNC_PID.  This value will be the same in
 1104:       both the pre- and post-xfer commands, so it can be used as a unique ID
 1105:       if the pre-xfer command wants to cache some arg/request info for the
 1106:       post-xfer command.
 1107: 
 1108:   INTERNAL:
 1109: 
 1110:     - Did a code audit using IBM's code-checker program and made several
 1111:       changes, including: replacing most of the strcpy() and sprintf()
 1112:       calls with strlcpy(), snprintf(), and memcpy(), adding a 0-value to
 1113:       an enum that had been intermingling a literal 0 with the defined enum
 1114:       values, silencing some uninitialized memory checks, marking some
 1115:       functions with a "noreturn" attribute, and changing an "if" that
 1116:       could never succeed on some platforms into a pre-processor directive
 1117:       that conditionally compiles the code.
 1118: 
 1119:     - Fixed a potential bug in f_name_cmp() when both the args are a
 1120:       top-level "." dir (which doesn't happen in normal operations).
 1121: 
 1122:     - Changed exit_cleanup() so that it can never return instead of exit.
 1123:       The old code might return if it found the exit_cleanup() function
 1124:       was being called recursively.  The new code is segmented so that
 1125:       any recursive calls move on to the next step of the exit-processing.
 1126: 
 1127:     - The macro WIFEXITED(stat) will now be defined if the OS didn't already
 1128:       define it.
 1129: 
 1130:   DEVELOPER RELATED:
 1131: 
 1132:     - The acls.diff and xattrs.diff patches have received a bunch of work to
 1133:       make them much closer to being acceptable in the main distribution.
 1134:       The xattrs patch also has some preliminary Mac OS X and FreeBSD
 1135:       compatibility code that various system types to exchange extended
 1136:       file-attributes.
 1137: 
 1138:     - A new diff in the patches dir, fake-root.diff, allows rsync to
 1139:       maintain a backup hierarchy with full owner, group, and device info
 1140:       without actually running as root.  It does this using a special
 1141:       extended attribute, so it depends on xattrs.diff (which depends on
 1142:       acls.diff).
 1143: 
 1144:     - The rsync.yo and rsyncd.conf.yo files have been updated to work
 1145:       better with the latest yodl 2.x releases.
 1146: 
 1147:     - Updated config.guess and config.sub to their 2006-07-02 versions.
 1148: 
 1149:     - Updated various files to include the latest FSF address and to have
 1150:       consistent opening comments.

 1153: NEWS for rsync 2.6.8 (22 Apr 2006)
 1154: Protocol: 29 (unchanged)
 1155: Changes since 2.6.7:
 1156: 
 1157:   BUG FIXES:
 1158: 
 1159:     - Fixed a bug in the exclude code where an anchored exclude without any
 1160:       wildcards fails to match an absolute source arg, but only when --relative
 1161:       is in effect.
 1162: 
 1163:     - Improved the I/O code for the generator to fix a potential hang when the
 1164:       receiver gets an EOF on the socket but the generator's select() call
 1165:       never indicates that the socket is writable for it to be notified about
 1166:       the EOF.  (This can happen when using stunnel).
 1167: 
 1168:     - Fixed a problem with the file-reading code where a failed read (such as
 1169:       that caused by a bad sector) would not advance the file's read-position
 1170:       beyond the failed read's data.
 1171: 
 1172:     - Fixed a logging bug where the "log file" directive was not being honored
 1173:       in a single-use daemon (one spawned by a remote-shell connection or by
 1174:       init).
 1175: 
 1176:     - If rsync cannot honor the --delete option, we output an error and exit
 1177:       instead of silently ignoring the option.
 1178: 
 1179:     - Fixed a bug in the --link-dest code that prevented special files (such as
 1180:       fifos) from being linked.
 1181: 
 1182:     - The ability to hard-link symlinks and special files is now determined at
 1183:       configure time instead of at runtime.  This fixes a bug with --link-dest
 1184:       creating a hard-link to a symlink's referent on a BSD system.
 1185: 
 1186:   ENHANCEMENTS:
 1187: 
 1188:     - In daemon mode, if rsync fails to bind to the requested port, the
 1189:       error(s) returned by socket() and/or bind() are now logged.
 1190: 
 1191:     - When we output a fatal error, we now output the version of rsync in the
 1192:       message.
 1193: 
 1194:     - Improved the documentation for the --owner and --group options.
 1195: 
 1196:     - The rsyncstats script in "support" has an improved line-parsing regex
 1197:       that is easier to read and also makes it to parse syslog-generated lines.
 1198: 
 1199:     - A new script in "support": file-attr-restore, can be used to restore the
 1200:       attributes of a file-set (the permissions, ownership, and group info)
 1201:       taken from the cached output of a "find ARG... -ls" command.
 1202: 
 1203:   DEVELOPER RELATED:
 1204: 
 1205:     - Removed the unused function write_int_named(), the unused variable
 1206:       io_read_phase, and the rarely used variable io_write_phase.  This also
 1207:       elides the confusing 'phase "unknown"' part of one error message.
 1208: 
 1209:     - Removed two unused configure checks and two related (also unused)
 1210:       compatibility functions.
 1211: 
 1212:     - The xattrs.diff patch received a security fix that prevents a potential
 1213:       buffer overflow in the receive_xattr() code.
 1214: 
 1215:     - The acls.diff patch has been improved quite a bit, with more to come.
 1216: 
 1217:     - A new patch was added: log-file.diff.  This contains an early version of
 1218:       a future option, --log-file=FILE, that will allow any rsync to log its
 1219:       actions to a file (something that only a daemon supports at present).
 1220: 
 1221: 
 1222: NEWS for rsync 2.6.7 (11 Mar 2006)
 1223: Protocol: 29 (unchanged)
 1224: Changes since 2.6.6:
 1225: 
 1226:   OUTPUT CHANGES:
 1227: 
 1228:     - The letter 'D' in the itemized output was being used for both devices
 1229:       (character or block) as well as other special files (such as fifos and
 1230:       named sockets).  This has changed to separate non-device special files
 1231:       under the 'S' designation (e.g. "cS+++++++ path/fifo").  See also the
 1232:       "--specials" option, below.
 1233: 
 1234:     - The way rsync escapes unreadable characters has changed.  First, rsync
 1235:       now has support for recognizing valid multibyte character sequences in
 1236:       your current locale, allowing it to escape fewer characters than before
 1237:       for a locale such as UTF-8.  Second, it now uses an escape idiom of
 1238:       "\#123", which is the literal string "\#" followed by exactly 3 octal
 1239:       digits.  Rsync no longer doubles a backslash character in a filename
 1240:       (e.g. it used to output "foo\\bar" when copying "foo\bar") -- now it only
 1241:       escapes a backslash that is followed by a hash-sign and 3 digits (0-9)
 1242:       (e.g. it will output "foo\#134#789" when copying "foo\#789").  See also
 1243:       the --8-bit-output (-8) option, mentioned below.
 1244: 
 1245:       Script writers: the local rsync is the one that outputs escaped names,
 1246:       so if you need to support unescaping of filenames for older rsyncs, I'd
 1247:       suggest that you parse the output of "rsync --version" and only use the
 1248:       old unescaping rules for 2.6.5 and 2.6.6.
 1249: 
 1250:   BUG FIXES:
 1251: 
 1252:     - Fixed a really old bug that caused --checksum (-c) to checksum all the
 1253:       files encountered during the delete scan (ouch).
 1254: 
 1255:     - Fixed a potential hang in a remote generator:  when the receiver gets a
 1256:       read-error on the socket, it now signals the generator about this so that
 1257:       the generator does not try to send any of the terminating error messages
 1258:       to the client (avoiding a potential hang in some setups).
 1259: 
 1260:     - Made hard-links work with symlinks and devices again.
 1261: 
 1262:     - If the sender gets an early EOF reading a source file, we propagate this
 1263:       error to the receiver so that it can discard the file and try requesting
 1264:       it again (which is the existing behavior for other kinds of read errors).
 1265: 
 1266:     - If a device-file/special-file changes permissions, rsync now updates the
 1267:       permissions without recreating the file.
 1268: 
 1269:     - If the user specifies a remote-host for both the source and destination,
 1270:       we now output a syntax error rather than trying to open the destination
 1271:       hostspec as a filename.
 1272: 
 1273:     - When --inplace creates a new destination file, rsync now creates it with
 1274:       permissions 0600 instead of 0000 -- this makes restarting possible when
 1275:       the transfer gets interrupted in the middle of sending a new file.
 1276: 
 1277:     - Reject the combination of --inplace and --sparse since the sparse-output
 1278:       algorithm doesn't work when overwriting existing data.
 1279: 
 1280:     - Fixed the directory name in the error that is output when pop_dir()
 1281:       fails.
 1282: 
 1283:     - Really fixed the parsing of a "!" entry in .cvsignore files this time.
 1284: 
 1285:     - If the generator gets a stat() error on a file, output it (this used to
 1286:       require at least -vv for the error to be seen).
 1287: 
 1288:     - If waitpid() fails or the child rsync didn't exit cleanly, we now handle
 1289:       the exit status properly and generate a better error.
 1290: 
 1291:     - Fixed some glitches in the double-verbose output when using --copy-dest,
 1292:       --link-dest, or --compare-dest.  Also improved how the verbose output
 1293:       handles hard-links (within the transfer) that had an up-to-date alternate
 1294:       "dest" file, and copied files (via --copy-dest).
 1295: 
 1296:     - Fixed the matching of the dont-compress items (e.g. *.gz) against files
 1297:       that have a path component containing a slash.
 1298: 
 1299:     - If the code reading a filter/exclude file gets an EINTR error, rsync now
 1300:       clears the error flag on the file handle so it can keep on reading.
 1301: 
 1302:     - If --relative is active, the sending side cleans up trailing "/" or "/."
 1303:       suffixes to avoid triggering a bug in older rsync versions.  Also, we now
 1304:       reject a ".." dir if it would be sent as a relative dir.
 1305: 
 1306:     - If a non-directory is in the way of a directory and rsync is run with
 1307:       --dry-run and --delete, rsync no longer complains about not being able
 1308:       to opendir() the not-yet present directory.
 1309: 
 1310:     - When --list-only is used and a non-existent local destination dir was
 1311:       also specified as a destination, rsync no longer generates a warning
 1312:       about being unable to create the missing directory.
 1313: 
 1314:     - Fixed some problems with --relative --no-implied-dirs when the
 1315:       destination directory did not yet exist:  we can now create a symlink or
 1316:       device when it is the first thing in the missing dir, and --fuzzy no
 1317:       longer complains about being unable to open the missing dir.
 1318: 
 1319:     - Fixed a bug where the --copy-links option would not affect implied
 1320:       directories without --copy-unsafe-links (see --relative).
 1321: 
 1322:     - Got rid of the need for --force to be used in some circumstances with
 1323:       --delete-after (making it consistent with --delete-before/-during).
 1324: 
 1325:     - Rsync now ignores the SIGXFSZ signal, just in case your OS sends this
 1326:       when a file is too large (rsync handles the write error).
 1327: 
 1328:     - Fixed a bug in the Proxy-Authorization header's base64-encoded value: it
 1329:       was not properly padded with trailing '=' chars.  This only affects a
 1330:       user that need to use a password-authenticated proxy for an outgoing
 1331:       daemon-rsync connection.
 1332: 
 1333:     - If we're transferring an empty directory to a new name, rsync no longer
 1334:       forces S_IWUSR if it wasn't already set, nor does it accidentally leave
 1335:       it set.
 1336: 
 1337:     - Fixed a bug in the debug output (-vvvvv) that could mention the wrong
 1338:       checksum for the current file offset.
 1339: 
 1340:     - Rsync no longer allows a single directory to be copied over a non-
 1341:       directory destination arg.
 1342: 
 1343:   ENHANCEMENTS:
 1344: 
 1345:     - Added the --append option that makes rsync append data onto files that
 1346:       are longer on the source than the destination (this includes new files).
 1347: 
 1348:     - Added the --min-size=SIZE option to exclude small files from the
 1349:       transfer.
 1350: 
 1351:     - Added the --compress-level option to allow you to set how aggressive
 1352:       rsync's compression should be (this option implies --compress).
 1353: 
 1354:     - Enhanced the parsing of the SIZE value for --min-size and --max-size to
 1355:       allow easy entry of multiples of 1000 (instead of just multiples of 1024)
 1356:       and off-by-one values too (e.g. --max-size=8mb-1).
 1357: 
 1358:     - Added the --8-bit-output (-8) option, which tells rsync to avoid escaping
 1359:       high-bit characters that it thinks are unreadable in the current locale.
 1360: 
 1361:     - The new option --human-readable (-h) changes the output of --progress,
 1362:       --stats, and the end-of-run summary to be easier to read.  If repeated,
 1363:       the units become powers of 1024 instead of powers of 1000.  (The old
 1364:       meaning of -h, as a shorthand for --help, still works as long as you
 1365:       just use it on its own, as in "rsync -h".)
 1366: 
 1367:     - If lutimes() and/or lchmod() are around, use them to allow the
 1368:       preservation of attributes on symlinks.
 1369: 
 1370:     - The --link-dest option now affects symlinks and devices (when possible).
 1371: 
 1372:     - Added two config items to the rsyncd.conf parsing:  "pre-xfer exec" and
 1373:       "post-xfer exec".  These allow a command to be specified on a per-module
 1374:       basis that will be run before and/or after a daemon-mode transfer.  (See
 1375:       the man page for a list of the environment variables that are set with
 1376:       information about the transfer.)
 1377: 
 1378:     - When using the --relative option, you can now insert a dot dir in
 1379:       the source path to indicate where the replication of the source dirs
 1380:       should start.  For example, if you specify a source path of
 1381:       rsync://host/module/foo/bar/./baz/dir with -R, rsync will now only
 1382:       replicate the "baz/dir" part of the source path (note: a trailing
 1383:       dot dir is unaffected unless it also has a trailing slash).
 1384: 
 1385:     - Added some new --no-FOO options that make it easier to override unwanted
 1386:       implied or default options.  For example, "-a --no-o" (aka "--archive
 1387:       --no-owner") can be used to turn off the preservation of file ownership
 1388:       that is implied by -a.
 1389: 
 1390:     - Added the --chmod=MODE option that allows the destination permissions to
 1391:       be changed from the source permissions.  E.g. --chmod=g+w,o-rwx
 1392: 
 1393:     - Added the "incoming chmod" and "outgoing chmod" daemon options that allow
 1394:       a module to specify what permissions changes should be applied to all
 1395:       files copied to and from the daemon.
 1396: 
 1397:     - Allow the --temp-dir option to be specified when starting a daemon, which
 1398:       sets the default temporary directory for incoming files.
 1399: 
 1400:     - If --delete is combined with --dirs without --recursive, rsync will now
 1401:       delete in any directory whose content is being synchronized.
 1402: 
 1403:     - If --backup is combined with --delete without --backup-dir (and without
 1404:       --delete-excluded), we add a "protect" filter-rule to ensure that files
 1405:       with the backup suffix are not deleted.
 1406: 
 1407:     - The file-count stats that are output by --progress were improved to
 1408:       better indicate what the numbers mean.  For instance, the output:
 1409:       "(xfer#5, to-check=8383/9999)" indicates that this was the fifth file
 1410:       to be transferred, and we still need to check 8383 more files out of
 1411:       a total of 9999.
 1412: 
 1413:     - The include/exclude code now allows a dir/*** directive (with 3 trailing
 1414:       stars) to match both the dir itself as well as all the content below the
 1415:       dir (dir/** would not match the dir).
 1416: 
 1417:     - Added the --prune-empty-dirs (-m) option that makes the receiving rsync
 1418:       discard empty chains of directories from the file-list.  This makes it
 1419:       easier to selectively copy files from a source hierarchy and end up with
 1420:       just the directories needed to hold the resulting files.
 1421: 
 1422:     - If the --itemize-changes (-i) option is repeated, rsync now includes
 1423:       unchanged files in the itemized output (similar to -vv, but without all
 1424:       the other verbose messages that can get in the way).  Of course, the
 1425:       client must be version 2.6.7 for this to work, but the remote rsync only
 1426:       needs to be 2.6.7 if you're pushing files.
 1427: 
 1428:     - Added the --specials option to tell rsync to copy non-device special
 1429:       files (which rsync now attempts even as a normal user).  The --devices
 1430:       option now requests the copying of just devices (character and block).
 1431:       The -D option still requests both (e.g. --devices and --specials), -a
 1432:       still implies -D, and non-root users still get a silent downgrade that
 1433:       omits device copying.
 1434: 
 1435:     - Added the --super option to make the receiver always attempt super-user
 1436:       activities.  This is useful for systems that allow things such as devices
 1437:       to be created or ownership to be set without being UID 0, and is also
 1438:       useful for someone who wants to ensure that errors will be output if the
 1439:       receiving rsync isn't being run as root.
 1440: 
 1441:     - Added the --sockopts option for those few who want to customize the TCP
 1442:       options used to contact a daemon rsync.
 1443: 
 1444:     - Added a way for the --temp-dir option to be combined with a partial-dir
 1445:       setting that lets rsync avoid non-atomic updates (for those times when
 1446:       --temp-dir is not being used because space is tight).
 1447: 
 1448:     - A new support script, files-to-excludes, will transform a list of files
 1449:       into a set of include/exclude directives that will copy those files.
 1450: 
 1451:     - A new option, --executability (-E) can be used to preserve just the
 1452:       execute bit on files, for those times when using the --perms option is
 1453:       not desired.
 1454: 
 1455:     - The daemon now logs each connection and also each module-list request
 1456:       that it receives.
 1457: 
 1458:     - New log-format options: %M (modtime), %U (uid), %G (gid), and %B
 1459:       (permission bits, e.g. "rwxr-xrwt").
 1460: 
 1461:     - The --dry-run option no longer forces the enabling of --verbose.
 1462: 
 1463:     - The --remove-sent-files option now does a better job of incrementally
 1464:       removing the sent files on the sending side (older versions tended to
 1465:       clump up all the removals at the end).
 1466: 
 1467:     - A daemon now supersedes its minimal SIGCHLD handler with the standard
 1468:       PID-remembering version after forking.  This ensures that the generator
 1469:       can get the child-exit status from the receiver.
 1470: 
 1471:     - Use of the --bwlimit option no longer interferes with the remote rsync
 1472:       sending error messages about invalid/refused options.
 1473: 
 1474:     - Rsync no longer returns a usage error when used with one local source arg
 1475:       and no destination: this now implies the --list-only option, just like
 1476:       the comparable situation with a remote source arg.
 1477: 
 1478:     - Added the --copy-dirlinks option, a more limited version of --copy-links.
 1479: 
 1480:     - Various documentation improvements, including: a better synopsis, some
 1481:       improved examples, a better discussion of the presence and absence of
 1482:       --perms (including how it interacts with the new --executability and
 1483:       --chmod options), an extended discussion of --temp-dir, an improved
 1484:       discussion of --partial-dir, a better description of rsync's pattern
 1485:       matching characters, an improved --no-implied-dirs section, and the
 1486:       documenting of what the --stats option outputs.
 1487: 
 1488:     - Various new and updated diffs in the patches dir, including: acls.diff,
 1489:       xattrs.diff, atimes.diff, detect-renamed.diff, and slp.diff.
 1490: 
 1491:   INTERNAL:
 1492: 
 1493:     - We now use sigaction() and sigprocmask() if possible, and fall back on
 1494:       signal() if not.  Using sigprocmask() ensures that rsync enables all the
 1495:       signals that it needs, just in case it was started in a masked state.
 1496: 
 1497:     - Some buffer sizes were expanded a bit, particularly on systems where
 1498:       MAXPATHLEN is overly small (e.g. cygwin).
 1499: 
 1500:     - If io_printf() tries to format more data than fits in the buffer, exit
 1501:       with an error instead of transmitting a truncated buffer.
 1502: 
 1503:     - If a va_copy macro is defined, lib/snprintf.c will use it when defining
 1504:       the VA_COPY macro.
 1505: 
 1506:     - Reduced the amount of stack memory needed for each level of directory
 1507:       recursion by nearly MAXPATHLEN bytes.
 1508: 
 1509:     - The wildmatch function was extended to allow an array of strings to be
 1510:       supplied as the string to match.  This allows the exclude code to do less
 1511:       string copying.
 1512: 
 1513:     - Got rid of the safe_fname() function (and all the myriad calls) and
 1514:       replaced it with a new function in the log.c code that filters all the
 1515:       output going to the terminal.
 1516: 
 1517:     - Unified the f_name() and the f_name_to() functions.
 1518: 
 1519:     - Improved the hash-table code the sender uses to handle checksums to make
 1520:       it use slightly less memory and run just a little faster.
 1521: 
 1522:   DEVELOPER RELATED:
 1523: 
 1524:     - The diffs in the patches dir now require "patch -p1 <DIFF" instead of
 1525:       the previous -p0.  Also, the version included in the release tar now
 1526:       affect generated files (e.g. configure, rsync.1, proto.h, etc.), so
 1527:       it is no longer necessary to run autoconf and/or yodl unless you're
 1528:       applying a patch that was checked out from CVS.
 1529: 
 1530:     - Several diffs in the patches dir now use the proper --enable-FOO
 1531:       configure option instead of --with-FOO to turn on the inclusion of
 1532:       the newly patched feature.
 1533: 
 1534:     - There is a new script, "prepare-source" than can be used to update the
 1535:       various generated files (proto.h, configure, etc.) even before configure
 1536:       has created the Makefile (this is mainly useful when patching the source
 1537:       with a patch that doesn't affect generated files).
 1538: 
 1539:     - The testsuite now sets HOME so that it won't be affected by a file such
 1540:       as ~/.popt.

 1543: NEWS for rsync 2.6.6 (28 Jul 2005)
 1544: Protocol: 29 (unchanged)
 1545: Changes since 2.6.5:
 1546: 
 1547:   SECURITY FIXES:
 1548: 
 1549:     - The zlib code was upgraded to version 1.2.3 in order to make it more
 1550:       secure.  While the widely-publicized security problem in zlib 1.2.2 did
 1551:       not affect rsync, another security problem surfaced that affects rsync's
 1552:       zlib 1.1.4.
 1553: 
 1554:   BUG FIXES:
 1555: 
 1556:     - The setting of flist->high in clean_flist() was wrong for an empty list.
 1557:       This could cause flist_find() to crash in certain rare circumstances
 1558:       (e.g. if just the right directory setup was around when --fuzzy was
 1559:       combined with --link-dest).
 1560: 
 1561:     - The outputting of hard-linked files when verbosity was > 1 was not right:
 1562:       (1) Without -i it would output the name of each hard-linked file as
 1563:       though it had been changed; it now outputs a "is hard linked" message for
 1564:       the file. (2) With -i it would output all dots for the unchanged
 1565:       attributes of a hard-link; it now changes those dots to spaces, as is
 1566:       done for other totally unchanged items.
 1567: 
 1568:     - When backing up a changed symlink or device, get rid of any old backup
 1569:       item so that we don't get an "already exists" error.
 1570: 
 1571:     - A couple places that were comparing a local and a remote modification-
 1572:       time were not honoring the --modify-window option.
 1573: 
 1574:     - Fixed a bug where the 'p' (permissions) itemized-changes flag might get
 1575:       set too often (if some non-significant mode bits differed).
 1576: 
 1577:     - Fixed a really old, minor bug that could cause rsync to warn about being
 1578:       unable to mkdir() a path that ends in "/." because it just created the
 1579:       directory (required --relative, --no-implied-dirs, a source path that
 1580:       ended in either a trailing slash or a trailing "/.", and a non-existing
 1581:       destination dir to tickle the bug in a recent version).
 1582: 
 1583:   ENHANCEMENTS:
 1584: 
 1585:     - Made the "max verbosity" setting in the rsyncd.conf file settable on a
 1586:       per-module basis (which now matches the documentation).
 1587: 
 1588:     - The support/rrsync script has been upgraded to verify the args of options
 1589:       that take args (instead of rejecting any such options).  The script was
 1590:       also changed to try to be more secure and to fix a problem in the parsing
 1591:       of a pull operation that has multiple sources.
 1592: 
 1593:     - Improved the documentation that explains the difference between a
 1594:       normal daemon transfer and a daemon-over remote-shell transfer.
 1595: 
 1596:     - Some of the diffs supplied in the patches dir were fixed and/or
 1597:       improved.
 1598: 
 1599:   BUILD CHANGES:
 1600: 
 1601:     - Made configure define NOBODY_USER (currently hard-wired to "nobody") and
 1602:       NOBODY_GROUP (set to either "nobody" or "nogroup" depending on what we
 1603:       find in the /etc/group file).
 1604: 
 1605:     - Added a test to the test suite, itemized.test, that tests the output of
 1606:       -i (log-format w/%i) and some double-verbose messages.
 1607:

 1609: NEWS for rsync 2.6.5 (1 Jun 2005)
 1610: Protocol: 29 (unchanged)
 1611: Changes since 2.6.4:
 1612: 
 1613:   OUTPUT CHANGES:
 1614: 
 1615:     - Non-printable chars in filenames are now output using backslash-
 1616:       escaped characters rather than '?'s.  Any non-printable character is
 1617:       output using 3 digits of octal (e.g. "\n" -> "\012"), and a backslash
 1618:       is now output as "\\".  Rsync also uses your locale setting, which
 1619:       can make it treat fewer high-bit characters as non-printable.
 1620: 
 1621:     - If rsync received an empty file-list when pulling files, it would
 1622:       output a "nothing to do" message and exit with a 0 (success) exit
 1623:       status, even if the remote rsync returned an error (it did not do
 1624:       this under the same conditions when pushing files).  This was changed
 1625:       to make the pulling behavior the same as the pushing behavior:  we
 1626:       now do the normal end-of-run outputting (depending on options) and
 1627:       exit with the appropriate exit status.
 1628: 
 1629:   BUG FIXES:
 1630: 
 1631:     - A crash bug was fixed when a daemon had its "path" set to "/", did
 1632:       not have chroot enabled, and used some anchored excludes in the
 1633:       rsyncd.conf file.
 1634: 
 1635:     - Fixed a bug in the transfer of a single file when -H is specified
 1636:       (rsync would either infinite loop or perhaps crash).
 1637: 
 1638:     - Fixed a case where the generator might try (and fail) to tweak the
 1639:       write-permissions of a read-only directory in list-only mode (this
 1640:       only caused an annoying warning message).
 1641: 
 1642:     - If --compare-dest or --link-dest uses a locally-copied file as the
 1643:       basis for an updated version, log this better when --verbose or -i
 1644:       is in effect.
 1645: 
 1646:     - Fixed the accidental disabling of --backup during the --delete-after
 1647:       processing.
 1648: 
 1649:     - Restored the ability to use the --address option in client mode (in
 1650:       addition to its use in daemon mode).
 1651: 
 1652:     - Make sure that some temporary progress information from the delete
 1653:       processing does not get left on the screen when it is followed by a
 1654:       newline.
 1655: 
 1656:     - When --existing skips a directory with extra verbosity, refer to it
 1657:       as a "directory", not a "file".
 1658: 
 1659:     - When transferring a single file to a different-named file, any
 1660:       generator messages that are source-file related no longer refer to
 1661:       the file by the destination filename.
 1662: 
 1663:     - Fixed a bug where hard-linking a group of files might fail if the
 1664:       generator hasn't created a needed destination directory yet.
 1665: 
 1666:     - Fixed a bug where a hard-linked group of files that is newly-linked
 1667:       to a file in a --link-dest dir doesn't link the files from the rest
 1668:       of the cluster.
 1669: 
 1670:     - When deleting files with the --one-file-system (-x) option set, rsync
 1671:       no longer tries to remove files from inside a mount-point on the
 1672:       receiving side.  Also, we don't complain about being unable to remove
 1673:       the mount-point dir.
 1674: 
 1675:     - Fixed a compatibility problem when using --cvs-ignore (-C) and
 1676:       sending files to an older rsync without using --delete.
 1677: 
 1678:     - Make sure that a "- !" or "+ !" include/exclude pattern does not
 1679:       trigger the list-clearing action that is reserved for "!".
 1680: 
 1681:     - Avoid a timeout in the generator when the sender/receiver aren't
 1682:       handling the generator's checksum output quickly enough.
 1683: 
 1684:     - Fixed the omission of some directories in the delete processing when
 1685:       --relative (-R) was combined with a source path that had a trailing
 1686:       slash.
 1687: 
 1688:     - Fixed a case where rsync would erroneously delete some files and then
 1689:       re-transfer them when the options --relative (-R) and --recursive
 1690:       (-r) were both enabled (along with --delete) and a source path had a
 1691:       trailing slash.
 1692: 
 1693:     - Make sure that --max-size doesn't affect a device or a symlink.
 1694: 
 1695:     - Make sure that a system with a really small MAXPATHLEN does not cause
 1696:       the buffers in readfd_unbuffered() to be too small to receive normal
 1697:       messages.  (This mainly affected Cygwin.)
 1698: 
 1699:     - If a source pathname ends with a filename of "..", treat it as if
 1700:       "../" had been specified (so that we don't copy files to the parent
 1701:       dir of the destination).
 1702: 
 1703:     - If --delete is combined with a file-listing rsync command (i.e. no
 1704:       transfer is happening), avoid outputting a warning that we couldn't
 1705:       delete anything.
 1706: 
 1707:     - If --stats is specified with --delete-after, ensure that all the
 1708:       "deleting" messages are output before the statistics.
 1709: 
 1710:     - Improved one "if" in the deletion code that was only checking errno
 1711:       for ENOTEMPTY when it should have also been checking for EEXIST (for
 1712:       compatibility with OS variations).
 1713: 
 1714:   ENHANCEMENTS:
 1715: 
 1716:     - Added the --only-write-batch=FILE option that may be used (instead
 1717:       of --write-batch=FILE) to create a batch file without doing any
 1718:       actual updating of the destination.  This allows you to divert all
 1719:       the file-updating data away from a slow data link (as long as you
 1720:       are pushing the data to the remote server when creating the batch).
 1721: 
 1722:     - When the generator is taking a long time to fill up its output buffer
 1723:       (e.g. if the transferred files are few, small, or missing), it now
 1724:       periodically flushes the output buffer so that the sender/receiver
 1725:       can get started on the files sooner rather than later.
 1726: 
 1727:     - Improved the keep-alive code to handle a long silence between the
 1728:       sender and the receiver that can occur when the sender is receiving
 1729:       the checksum data for a large file.
 1730: 
 1731:     - Improved the auth-errors that are logged by the daemon to include
 1732:       some information on why the authorization failed:  wrong user,
 1733:       password mismatch, etc.  (The client-visible message is unchanged!)
 1734: 
 1735:     - Improved the client's handling of an "@ERROR" from a daemon so that
 1736:       it does not complain about an unexpectedly closed socket (since we
 1737:       really did expect the socket to close).
 1738: 
 1739:     - If the daemon can't open the log-file specified in rsyncd.conf, fall
 1740:       back to using syslog and log an appropriate warning.  This is better
 1741:       than what was typically a totally silent (and fatal) failure (since a
 1742:       daemon is not usually run with the --no-detach option that was
 1743:       necessary to see the error on stderr).
 1744: 
 1745:     - The man pages now consistently refer to an rsync daemon as a "daemon"
 1746:       instead of a "server" (to distinguish it from the server process in a
 1747:       non-daemon transfer).
 1748: 
 1749:     - Made a small change to the rrsync script (restricted rsync -- in the
 1750:       support dir) to make a read-only server reject all --remove-* options
 1751:       when sending files (to future-proof it against the possibility of
 1752:       other similar options being added at some point).
 1753: 
 1754:   INTERNAL:
 1755: 
 1756:     - Rsync now calls setlocale(LC_CTYPE, "").  This enables isprint() to
 1757:       better discern which filename characters need to be escaped in
 1758:       messages (which should result in fewer escaped characters in some
 1759:       locales).
 1760: 
 1761:     - Improved the naming of the log-file open/reopen/close functions.
 1762: 
 1763:     - Removed some protocol-compatibility code that was only needed to help
 1764:       someone running a pre-release of 2.6.4.
 1765: 
 1766:   BUILD CHANGES:
 1767: 
 1768:     - Added configure option "--disable-locale" to disable any use of
 1769:       setlocale() in the binary.
 1770: 
 1771:     - Fixed a bug in the SUPPORT{,_HARD}_LINKS #defines which prevented
 1772:       rsync from being built without symlink or hard-link support.
 1773: 
 1774:     - Only #define HAVE_REMSH if it is going to be set to 1.
 1775: 
 1776:     - Configure now disables the use of mkstemp() under HP-UX (since they
 1777:       refuse to fix its broken handling of large files).
 1778: 
 1779:     - Configure now explicitly checks for the lseek64() function so that
 1780:       the code can use HAVE_LSEEK64 instead of inferring lseek64()'s
 1781:       presence based on the presence of the off64_t type.
 1782: 
 1783:     - Configure no longer mentions the change in the default remote-shell
 1784:       (from rsh to ssh) that occurred for the 2.6.0 release.
 1785: 
 1786:     - Some minor enhancements to the test scripts.
 1787: 
 1788:     - Added a few new *.diff files to the patches dir, including a patch
 1789:       that enables the optional copying of extended attributes.

 1792: NEWS for rsync 2.6.4 (30 March 2005)
 1793: Protocol: 29 (changed)
 1794: Changes since 2.6.3:
 1795: 
 1796:   OUTPUT CHANGES:
 1797: 
 1798:     - When rsync deletes a directory and outputs a verbose message about
 1799:       it, it now appends a trailing slash to the name instead of (only
 1800:       sometimes) outputting a preceding "directory " string.
 1801: 
 1802:     - The --stats output will contain file-list time-statistics if both
 1803:       sides are 2.6.4, or if the local side is 2.6.4 and the files are
 1804:       being pushed (since the stats come from the sending side).
 1805:       (Requires protocol 29 for a pull.)
 1806: 
 1807:     - The "%o" (operation) log-format escape now has a third value (besides
 1808:       "send" and "recv"):  "del." (with trailing dot to make it 4 chars).
 1809:       This changes the way deletions are logged in the daemon's log file.
 1810: 
 1811:     - When the --log-format option is combined with --verbose, rsync now
 1812:       avoids outputting the name of the file twice in most circumstances.
 1813:       As long as the --log-format item does not refer to any post-transfer
 1814:       items (such as %b or %c), the --log-format message is output prior to
 1815:       the transfer, so --verbose is now the equivalent of a --log-format of
 1816:       '%n%L' (which outputs the name and any link info).  If the log output
 1817:       must occur after the transfer to be complete, the only time the name
 1818:       is also output prior to the transfer is when --progress was specified
 1819:       (so that the name will precede the progress stats, and the full
 1820:       --log-format output will come after).
 1821: 
 1822:     - Non-printable characters in filenames are replaced with a '?' to
 1823:       avoid corrupting the screen or generating empty lines in the output.
 1824:   
 1825:   BUG FIXES:
 1826: 
 1827:     - Restore the list-clearing behavior of "!" in a .cvsignore file (2.6.3
 1828:       was only treating it as a special token in an rsync include/exclude
 1829:       file).
 1830: 
 1831:     - The combination of --verbose and --dry-run now mentions the full list
 1832:       of changes that would be output without --dry-run.
 1833: 
 1834:     - Avoid a mkdir warning when removing a directory in the destination
 1835:       that already exists in the --backup-dir.
 1836: 
 1837:     - An OS that has a binary mode for its files (such as cygwin) needed
 1838:       setmode(fd, O_BINARY) called on the temp-file we opened with
 1839:       mkstemp().  (Fix derived from cygwin's 2.6.3 rsync package.)
 1840: 
 1841:     - Fixed a potential hang when verbosity is high, the client side is
 1842:       the sender, and the file-list is large.
 1843: 
 1844:     - Fixed a potential protocol-corrupting bug where the generator could
 1845:       merge a message from the receiver into the middle of a multiplexed
 1846:       packet of data if only part of that data had been written out to the
 1847:       socket when the message from the generator arrived.
 1848: 
 1849:     - We now check if the OS doesn't support using mknod() for creating
 1850:       FIFOs and sockets, and compile-in some compatibility code using
 1851:       mkfifo() and socket() when necessary.
 1852: 
 1853:     - Fixed an off-by-one error in the handling of --max-delete=N.  Also,
 1854:       if the --max-delete limit is exceeded during a run, we now output a
 1855:       warning about this at the end of the run and exit with a new error
 1856:       code (25).
 1857: 
 1858:     - One place in the code wasn't checking if fork() failed.
 1859: 
 1860:     - The "ignore nonreadable" daemon parameter used to erroneously affect
 1861:       readable symlinks that pointed to a non-existent file.
 1862: 
 1863:     - If the OS does not have lchown() and a chown() of a symlink will
 1864:       affect the referent of a symlink (as it should), we no longer try
 1865:       to set the user and group of a symlink.
 1866: 
 1867:     - The generator now properly runs the hard-link loop and the dir-time
 1868:       rewriting loop after we're sure that the redo phase is complete.
 1869: 
 1870:     - When --backup was specified with --partial-dir=DIR, where DIR is a
 1871:       relative path, the backup code was erroneously trying to backup a
 1872:       file that was put into the partial-dir.
 1873: 
 1874:     - If a file gets resent in a single transfer and the --backup option is
 1875:       enabled along with --inplace, rsync no longer performs a duplicate
 1876:       backup (it used to overwrite the first backup with the failed file).
 1877: 
 1878:     - One call to flush_write_file() was not being checked for an error.
 1879: 
 1880:     - The --no-relative option was not being sent from the client to a
 1881:       server sender.
 1882: 
 1883:     - If an rsync daemon specified "dont compress = ..." for a file and the
 1884:       client tried to specify --compress, the libz code was not handling a
 1885:       compression level of 0 properly.  This could cause a transfer failure
 1886:       if the block-size for a file was large enough (e.g. rsync might have
 1887:       exited with an error for large files).
 1888: 
 1889:     - Fixed a bug that would sometimes surface when using --compress and
 1890:       sending a file with a block-size larger than 64K (either manually
 1891:       specified, or computed due to the file being really large).  Prior
 1892:       versions of rsync would sometimes fail to decompress the data
 1893:       properly, and thus the transferred file would fail its verification.
 1894: 
 1895:     - If a daemon can't open the specified log file (i.e. syslog is not
 1896:       being used), die without crashing.  We also output an error about
 1897:       the failure on stderr (which will only be seen if --no-detach was
 1898:       specified) and exit with a new error code (6).
 1899: 
 1900:     - A local transfer no longer duplicates all its include/exclude options
 1901:       (since the forked process already has a copy of the exclude list,
 1902:       there's no need to send them a set of duplicates).
 1903: 
 1904:     - The output of the items that are being updated by the generator (dirs,
 1905:       symlinks, devices) is now intermingled in the proper order with the
 1906:       output from the items that the receiver is updating (regular files)
 1907:       when pulling.  This misordering was particularly bad when --progress
 1908:       was specified.  (Requires protocol 29.)
 1909: 
 1910:     - When --timeout is specified, lulls that occur in the transfer while
 1911:       the generator is doing work that does not generate socket traffic
 1912:       (looking for changed files, deleting files, doing directory-time
 1913:       touch-ups, etc.) will cause a new keep-alive packet to be sent that
 1914:       should keep the transfer going as long as the generator continues to
 1915:       make progress.  (Requires protocol 29.)
 1916: 
 1917:     - The stat size of a device is not added to the total file size of the
 1918:       items in the transfer (the size might be undefined on some OSes).
 1919: 
 1920:     - Fixed a problem with refused-option messages sometimes not making it
 1921:       back to the client side when a remote --files-from was in effect and
 1922:       the daemon was the receiver.
 1923: 
 1924:     - The --compare-dest option was not updating a file that differed in
 1925:       (the preserved) attributes from the version in the compare-dest DIR.
 1926: 
 1927:     - When rsync is copying files into a write-protected directory, fixed
 1928:       the change-report output for the directory so that we don't report
 1929:       an identical directory as changed.
 1930: 
 1931:   ENHANCEMENTS:
 1932: 
 1933:     - Rsync now supports popt's option aliases, which means that you can
 1934:       use /etc/popt and/or ~/.popt to create your own option aliases.
 1935: 
 1936:     - Added the --delete-during (--del) option which will delete files
 1937:       from the receiving side incrementally as each directory in the
 1938:       transfer is being processed.  This makes it more efficient than the
 1939:       default, before-the-transfer behavior, which is now also available as
 1940:       --delete-before (and is still the default --delete-WHEN option that
 1941:       will be chosen if --delete or --delete-excluded is specified without
 1942:       a --delete-WHEN choice).  All the --del* options infer --delete, so
 1943:       an rsync daemon that refuses "delete" will still refuse to allow any
 1944:       file-deleting options (including the new --remove-sent-files option).
 1945: 
 1946:     - All the --delete-WHEN options are now more memory efficient:
 1947:       Previously an duplicate set of file-list objects was created on the
 1948:       receiving side for the entire destination hierarchy.  The new
 1949:       algorithm only creates one directory of objects at a time (for files
 1950:       inside the transfer).
 1951: 
 1952:     - Added the --copy-dest option, which works like --link-dest except
 1953:       that it locally copies identical files instead of hard-linking them.
 1954: 
 1955:     - Added support for specifying multiple --compare-dest, --copy-dest, or
 1956:       --link-dest options, but only of a single type. (Promoted from the
 1957:       patches dir and enhanced.) (Requires protocol 29.)
 1958: 
 1959:     - Added the --max-size option. (Promoted from the patches dir.)
 1960: 
 1961:     - The daemon-mode options are now separated from the normal rsync
 1962:       options so that they can't be mixed together.  This makes it
 1963:       impossible to start a daemon that has improper default option values
 1964:       (which could cause problems when a client connects, such as hanging
 1965:       or crashing).
 1966: 
 1967:     - The --bwlimit option may now be used in combination with --daemon
 1968:       to specify both a default value for the daemon side and a value
 1969:       that cannot be exceeded by a user-specified --bwlimit option.
 1970: 
 1971:     - Added the "port" parameter to the rsyncd.conf file. (Promoted from
 1972:       the patches dir.)  Also added "address".  The command-line options
 1973:       take precedence over a config-file option, as expected.
 1974: 
 1975:     - In _exit_cleanup(): when we are exiting with a partially-received
 1976:       file, we now flush any data in the write-cache before closing the
 1977:       partial file.
 1978: 
 1979:     - The --inplace support was enhanced to work with --compare-dest,
 1980:       --link-dest, and (the new) --copy-dest options. (Requires protocol
 1981:       29.)
 1982: 
 1983:     - Added the --dirs (-d) option for an easier way to copy directories
 1984:       without recursion.  Any directories that are encountered are created
 1985:       on the destination.  Specifying a directory with a trailing slash
 1986:       copies its immediate contents to the destination.
 1987: 
 1988:     - The --files-from option now implies --dirs (-d).
 1989: 
 1990:     - Added the --list-only option, which is mainly a way for the client to
 1991:       put the server into listing mode without needing to resort to any
 1992:       internal option kluges (e.g. the age-old use of "-r --exclude="/*/*"
 1993:       for a non-recursive listing).  This option is used automatically
 1994:       (behind the scenes) when a modern rsync speaks to a modern daemon,
 1995:       but may also be specified manually if you want to force the use of
 1996:       the --list-only option over a remote-shell connection.
 1997: 
 1998:     - Added the --omit-dir-times (-O) option, which will avoid updating
 1999:       the modified time for directories when --times was specified.  This
 2000:       option will avoid an extra pass through the file-list at the end of
 2001:       the transfer (to tweak all the directory times), which may provide
 2002:       an appreciable speedup for a really large transfer. (Promoted from
 2003:       the patches dir.)
 2004: 
 2005:     - Added the --filter (-f) option and its helper option, -F.  Filter
 2006:       rules are an extension to the existing include/exclude handling
 2007:       that also supports nested filter files as well as per-directory
 2008:       filter files (like .cvsignore, but with full filter-rule parsing).
 2009:       This new option was chosen in order to ensure that all existing
 2010:       include/exclude processing remained 100% compatible with older
 2011:       versions.  Protocol 29 is needed for full filter-rule support, but
 2012:       backward-compatible rules work with earlier protocol versions.
 2013:       (Promoted from the patches dir and enhanced.)
 2014: 
 2015:     - Added the --delay-updates option that puts all updated files into
 2016:       a temporary directory (by default ".~tmp~", but settable via the
 2017:       --partial-dir=DIR option) until the end of the transfer.  This
 2018:       makes the updates a little more atomic for a large transfer.
 2019: 
 2020:     - If rsync is put into the background, any output from --progress is
 2021:       reduced.
 2022: 
 2023:     - Documented the "max verbosity" setting for rsyncd.conf.  (This
 2024:       setting was added a couple releases ago, but left undocumented.)
 2025: 
 2026:     - The sender and the generator now double-check the file-list index
 2027:       they are given, and refuse to try to do a file transfer on a
 2028:       non-file index (since that would indicate that something had gone
 2029:       very wrong).
 2030: 
 2031:     - Added the --itemize-changes (-i) option, which is a way to output a
 2032:       more detailed list of what files changed and in what way.  The effect
 2033:       is the same as specifying a --log-format of "%i %n%L" (see both the
 2034:       rsync and rsyncd.conf manpages).  Works with --dry-run too.
 2035: 
 2036:     - Added the --fuzzy (-y) option, which attempts to find a basis file
 2037:       for a file that is being created from scratch.  The current algorithm
 2038:       only looks in the destination directory for the created file, but it
 2039:       does attempt to find a match based on size/mod-time (in case the file
 2040:       was renamed with no other changes) as well as based on a fuzzy
 2041:       name-matching algorithm.  This option requires protocol 29 because it
 2042:       needs the new file-sorting order.  (Promoted from patches dir and
 2043:       enhanced.) (Requires protocol 29.)
 2044: 
 2045:     - Added the --remove-sent-files option, which lets you move files
 2046:       between systems.
 2047: 
 2048:     - The hostname in HOST:PATH or HOST::PATH may now be an IPv6 literal
 2049:       enclosed in '[' and ']' (e.g. "[::1]").  (We already allowed IPv6
 2050:       literals in the rsync://HOST:PORT/PATH format.)
 2051: 
 2052:     - When rsync recurses to build the file list, it no longer keeps open
 2053:       one or more directory handles from the dir's parent dirs.
 2054: 
 2055:     - When building under windows, the default for --daemon is now to
 2056:       avoid detaching, requiring the new --detach option to force rsync
 2057:       to detach.
 2058: 
 2059:     - The --dry-run option can now be combined with either --write-batch or
 2060:       --read-batch, allowing you to run a do-nothing test command to see
 2061:       what would happen without --dry-run.
 2062: 
 2063:     - The daemon's "read only" config item now sets an internal read_only
 2064:       variable that makes extra sure that no write/delete calls on the
 2065:       read-only side can succeed.
 2066: 
 2067:     - The log-format % escapes can now have a numeric field width in
 2068:       between the % and the escape letter (e.g. "%-40n %08p").
 2069: 
 2070:     - Improved the option descriptions in the --help text.
 2071: 
 2072:   SUPPORT FILES:
 2073: 
 2074:     - Added atomic-rsync to the support dir: a perl script that will
 2075:       transfer some files using rsync, and then move the updated files into
 2076:       place all at once at the end of the transfer.  Only works when
 2077:       pulling, and uses --link-dest and a parallel hierarchy of files to
 2078:       effect its update.
 2079: 
 2080:     - Added mnt-excl to the support dir: a perl script that takes the
 2081:       /proc/mounts file and translates it into a set of excludes that will
 2082:       exclude all mount points (even mapped mounts to the same disk).  The
 2083:       excludes are made relative to the specified source dir and properly
 2084:       anchored.
 2085: 
 2086:     - Added savetransfer.c to the support dir: a C program that can make
 2087:       a copy of all the data that flows over the wire.  This lets you test
 2088:       for data corruption (by saving the data on both the sending side and
 2089:       the receiving side) and provides one way to debug a protocol error.
 2090: 
 2091:     - Added rrsync to the support dir: this is an updated version of Joe
 2092:       Smith's restricted rsync perl script.  This helps to ensure that only
 2093:       certain rsync commands can be run by an ssh invocation.
 2094: 
 2095:   INTERNAL:
 2096: 
 2097:     - Added better checking of the checksum-header values that come over
 2098:       the socket.
 2099: 
 2100:     - Merged a variety of file-deleting functions into a single function so
 2101:       that it is easier to maintain.
 2102: 
 2103:     - Improved the type of some variables (particularly blocksize vars) for
 2104:       consistency and proper size.
 2105: 
 2106:     - Got rid of the uint64 type (which we didn't need).
 2107: 
 2108:     - Use a slightly more compatible set of core #include directives.
 2109: 
 2110:     - Defined int32 in a way that ensures that the build dies if we can't
 2111:       find a variable with at least 32 bits.
 2112: 
 2113:   PROTOCOL DIFFERENCES FOR VERSION 29:
 2114: 
 2115:     - A 16-bit flag-word is transmitted after every file-list index.  This
 2116:       indicates what is changing between the sender and the receiver.  The
 2117:       generator now transmits an index and a flag-word to indicate when
 2118:       dirs and symlinks have changed (instead of producing a message),
 2119:       which makes the outputting of the information more consistent and
 2120:       less prone to screen corruption (because the local receiver/sender is
 2121:       now outputting all the file-change info messages).
 2122: 
 2123:     - If a file is being hard-linked, the ITEM_XNAME_FOLLOWS bit is enabled
 2124:       in the flag-word and the name of the file that was linked immediately
 2125:       follows in vstring format (see below).
 2126: 
 2127:     - If a file is being transferred with an alternate-basis file, the
 2128:       ITEM_BASIS_TYPE_FOLLOWS bit is enabled in the flag-word and a single
 2129:       byte follows, indicating what type of basis file was chosen.  If that
 2130:       indicates that a fuzzy-match was selected, the ITEM_XNAME_FOLLOWS bit
 2131:       is set in the flag-word and the name of the match in vstring format
 2132:       follows the basis byte.  A vstring is a variable length string that
 2133:       has its size written prior to the string, and no terminating null.
 2134:       If the string is from 1-127 bytes, the length is a single byte.  If
 2135:       it is from 128-32767 bytes, the length is written as ((len >> 8) |
 2136:       0x80) followed by (len % 0x100).
 2137: 
 2138:     - The sending of exclude names is done using filter-rule syntax.  This
 2139:       means that all names have a prefixed rule indicator, even excludes
 2140:       (which used to be sent as a bare pattern, when possible).  The -C
 2141:       option will include the per-dir .cvsignore merge file in the list of
 2142:       filter rules so it is positioned correctly (unlike in some older
 2143:       transfer scenarios).
 2144: 
 2145:     - Rsync sorts the filename list in a different way: it sorts the subdir
 2146:       names after the non-subdir names for each dir's contents, and it
 2147:       always puts a dir's contents immediately after the dir's name in the
 2148:       list.  (Previously an item named "foo.txt" would sort in between
 2149:       directory "foo/" and "foo/bar".)
 2150: 
 2151:     - When talking to a protocol 29 rsync daemon, a list-only request
 2152:       is able to note this before the options are sent over the wire and
 2153:       the new --list-only option is included in the options.
 2154: 
 2155:     - When the --stats bytes are sent over the wire (or stored in a batch),
 2156:       they now include two elapsed-time values: one for how long it took to
 2157:       build the file-list, and one for how long it took to send it over the
 2158:       wire (each expressed in thousandths of a second).
 2159: 
 2160:     - When --delete-excluded is specified with some filter rules (AKA
 2161:       excludes), a client sender will now initiate a send of the rules to
 2162:       the receiver (older protocols used to omit the sending of excludes in
 2163:       this situation since there were no receiver-specific rules that
 2164:       survived --delete-excluded back then).  Note that, as with all the
 2165:       filter-list sending, only items that are significant to the other
 2166:       side will actually be sent over the wire, so the filter-rule list
 2167:       that is sent in this scenario is often empty.
 2168: 
 2169:     - An index equal to the file-list count is sent as a keep-alive packet
 2170:       from the generator to the sender, which then forwards it on to the
 2171:       receiver.  This normally invalid index is only a valid keep-alive
 2172:       packet if the 16-bit flag-word that follows it contains a single bit
 2173:       (ITEM_IS_NEW, which is normally an illegal flag to appear alone).
 2174: 
 2175:     - A protocol-29 batch file includes a bit for the setting of the --dirs
 2176:       option and for the setting of the --compress option.  Also, the shell
 2177:       script created by --write-batch will use the --filter option instead
 2178:       of --exclude-from to capture any filter rules.
 2179: 
 2180:   BUILD CHANGES:
 2181: 
 2182:     - Handle an operating system that use mkdev() in place of makedev().
 2183: 
 2184:     - Improved configure to better handle cross-compiling.
 2185:

 2187: NEWS for rsync 2.6.3 (30 Sep 2004)
 2188: Protocol: 28 (unchanged)
 2189: Changes since 2.6.2:
 2190: 
 2191:   SECURITY FIXES:
 2192: 
 2193:     - A bug in the sanitize_path routine (which affects a non-chrooted
 2194:       rsync daemon) could allow a user to craft a pathname that would get
 2195:       transformed into an absolute path for certain options (but not for
 2196:       file-transfer names).  If you're running an rsync daemon with chroot
 2197:       disabled, *please upgrade*, ESPECIALLY if the user privs you run
 2198:       rsync under is anything above "nobody".
 2199: 
 2200:   OUTPUT CHANGES (ATTN: those using a script to parse the verbose output):
 2201: 
 2202:     - Please note that the 2-line footer (output when verbose) now uses the
 2203:       term "sent" instead of "wrote" and "received" instead of "read".  If
 2204:       you are not parsing the numeric values out of this footer, a script
 2205:       would be better off using the empty line prior to the footer as the
 2206:       indicator that the verbose output is over.
 2207:       
 2208:     - The output from the --stats option was similarly affected to change
 2209:       "written" to "sent" and "read" to "received".
 2210: 
 2211:     - Rsync ensures that a filename that contains a newline gets mentioned
 2212:       with each newline transformed into a question mark (which prevents a
 2213:       filename from causing an empty line to be output).
 2214: 
 2215:     - The "backed up ..." message that is output when at least 2 --verbose
 2216:       options are specified is now the same both with and without the
 2217:       --backup-dir option.
 2218: 
 2219:   BUG FIXES:
 2220: 
 2221:     - Fixed a crash bug that might appear when --delete was used and
 2222:       multiple source directories were specified.
 2223: 
 2224:     - Fixed a 32-bit truncation of the file length when generating the
 2225:       checksums.
 2226: 
 2227:     - The --backup code no longer attempts to create some directories
 2228:       over and over again (generating warnings along the way).
 2229: 
 2230:     - Fixed a bug in the reading of the secrets file (by the daemon) and
 2231:       the password file (by the client):  the files no longer need to be
 2232:       terminated by a newline for their content to be read in.
 2233: 
 2234:     - If a file has a read error on the sending side or the reconstructed
 2235:       data doesn't match the expected checksum (perhaps due to the basis
 2236:       file changing during the transfer), the receiver will no longer
 2237:       retain the resulting file unless the --partial option was specified.
 2238:       (Note: for the read-error detection to work, neither side can be
 2239:       older than 2.6.3 -- older receivers will always retain the file, and
 2240:       older senders don't tell the receiver that the file had a read
 2241:       error.)
 2242: 
 2243:     - If a file gets resent in a single transfer and the --backup option
 2244:       is enabled, rsync no longer performs a duplicate backup (it used to
 2245:       overwrite the original file in the backup area).
 2246: 
 2247:     - Files specified in the daemon's "exclude" or "exclude from" config
 2248:       items are now excluded from being uploaded (assuming that the module
 2249:       allows uploading at all) in addition to the old download exclusion.
 2250: 
 2251:     - Got rid of a potential hang in the receiver when near the end of a
 2252:       phase.
 2253: 
 2254:     - When using --backup without a --backup-dir, rsync no longer preserves
 2255:       the modify time on directories.  This avoids confusing NFS.
 2256: 
 2257:     - When --copy-links (-L) is specified, we now output a separate error
 2258:       for a symlink that has no referent instead of claiming that a file
 2259:       "vanished".
 2260: 
 2261:     - The --copy-links (-L) option no longer has the side-effect of telling
 2262:       the receiving side to follow symlinks.  See the --keep-dirlinks
 2263:       option (mentioned below) for a way to specify that behavior.
 2264: 
 2265:     - Error messages from the daemon server's option-parsing (such as
 2266:       refused options) are now successfully transferred back to the client
 2267:       (the server used to fail to send the message because the socket
 2268:       wasn't in the right state for the message to get through).
 2269: 
 2270:     - Most transfer errors that occur during a daemon transfer are now
 2271:       returned to the user in addition to being logged (some messages are
 2272:       intended to be daemon-only and are not affected by this).
 2273: 
 2274:     - Fixed a bug in the daemon authentication code when using one of the
 2275:       batch-processing options.
 2276: 
 2277:     - We try to work around some buggy IPv6 implementations that fail to
 2278:       implement IPV6_V6ONLY.  This should fix the "address in use" error
 2279:       that some daemons get when running on an OS with a buggy IPv6
 2280:       implementation.  Also, if the new code gets this error, we might
 2281:       suggest that the user specify --ipv4 or --ipv6 (if we think it will
 2282:       help).
 2283: 
 2284:     - When the remote rsync dies, make a better effort to recover any error
 2285:       messages it may have sent before dying (the local rsync used to just
 2286:       die with a socket-write error).
 2287: 
 2288:     - When using --delete and a --backup-dir that contains files that are
 2289:       hard-linked to their destination equivalents, rsync now makes sure
 2290:       that removed files really get removed (avoids a really weird rename()
 2291:       behavior).
 2292: 
 2293:     - Avoid a bogus run-time complaint about a lack of 64-bit integers when
 2294:       the int64 type is defined as an off_t and it actually has 64-bits.
 2295: 
 2296:     - Added a configure check for open64() without mkstemp64() so that we
 2297:       can avoid using mkstemp() when such a combination is encountered.
 2298:       This bypasses a problem writing out large temp files on OSes such as
 2299:       AIX and HP-UX.
 2300: 
 2301:     - Fixed an age-old crash problem with --read-batch on a local copy
 2302:       (rsync was improperly assuming --whole-file for the local copy).
 2303: 
 2304:     - When --dry-run (-n) is used and the destination directory does not
 2305:       exist, rsync now produces a correct report of files that would be
 2306:       sent instead of dying with a chdir() error.
 2307: 
 2308:     - Fixed a bug that could cause a slow-to-connect rsync daemon to die
 2309:       with an error instead of waiting for the connection to finish.
 2310: 
 2311:     - Fixed an ssh interaction that could cause output to be lost when the
 2312:       user chose to combine the output of rsync's stdout and stderr (e.g.
 2313:       using the "2>&1").
 2314: 
 2315:     - Fixed an option-parsing bug when --files-from got passed to a daemon.
 2316: 
 2317:   ENHANCEMENTS:
 2318: 
 2319:     - Added the --partial-dir=DIR option that lets you specify where to
 2320:       (temporarily) put a partially transferred file (instead of over-
 2321:       writing the destination file).  E.g.  --partial-dir=.rsync-partial
 2322:       Also added support for the RSYNC_PARTIAL_DIR environment variable
 2323:       that, when found, transforms a regular --partial option (such as
 2324:       the convenient -P option) into one that also specifies a directory.
 2325: 
 2326:     - Added --keep-dirlinks (-K), which allows you to symlink a directory
 2327:       onto another partition on the receiving side and have rsync treat it
 2328:       as matching a normal directory from the sender.
 2329: 
 2330:     - Added the --inplace option that tells rsync to write each destination
 2331:       file without using a temporary file.  The matching of existing data
 2332:       in the destination file can be severely limited by this, but there
 2333:       are also cases where this is more efficient (such as appending data).
 2334:       Use only when needed (see the man page for more details).
 2335: 
 2336:     - Added the "write only" option for the daemon's config file.
 2337: 
 2338:     - Added long-option names for -4 and -6 (namely --ipv4 and --ipv6)
 2339:       and documented all these options in the man page.
 2340: 
 2341:     - Improved the handling of the --bwlimit option so that it's less
 2342:       bursty, more accurate, and works properly over a larger range of
 2343:       values.
 2344: 
 2345:     - The rsync daemon-over-ssh code now looks for SSH_CONNECTION and
 2346:       SSH2_CLIENT in addition to SSH_CLIENT to figure out the IP address.
 2347: 
 2348:     - Added the --checksum-seed=N option for advanced users.
 2349: 
 2350:     - Batch writing/reading has a brand-new implementation that is simpler,
 2351:       fixes a few weird problems with the old code (such as no longer
 2352:       sprinkling the batch files into different dirs or even onto different
 2353:       systems), and is much less intrusive into the code (making it easier
 2354:       to maintain for the future).  The new code generates just one data
 2355:       file instead of three, which makes it possible to read the batch on
 2356:       stdin via a remote shell.  Also, the old requirement of forcing the
 2357:       same fixed checksum-seed for all batch processing has been removed.
 2358: 
 2359:     - If an rsync daemon has a module set with "list = no" (which hides its
 2360:       presence in the list of available modules), a user that fails to
 2361:       authenticate gets the same "unknown module" error that they would get
 2362:       if the module were actually unknown (while still logging the real
 2363:       error to the daemon's log file).  This prevents fishing for module
 2364:       names.
 2365: 
 2366:     - The daemon's "refuse options" config item now allows you to match
 2367:       option names using wildcards and/or the single-letter option names.
 2368: 
 2369:     - Each transferred file now gets its permissions and modified-time
 2370:       updated before the temp-file gets moved into place.  Previously, the
 2371:       finished file would have a very brief window where its permissions
 2372:       disallowed all group and world access.
 2373: 
 2374:     - Added the ability to parse a literal IPv6 address in an "rsync:" URL
 2375:       (e.g. rsync://[2001:638:500:101::21]:873/module/dir).
 2376: 
 2377:     - The daemon's wildcard expanding code can now handle more than 1000
 2378:       filenames (it's now limited by memory instead of having a hard-wired
 2379:       limit).
 2380: 
 2381:   INTERNAL:
 2382: 
 2383:     - Some cleanup in the exclude code has saved some per-exclude memory
 2384:       and made the code easier to maintain.
 2385: 
 2386:     - Improved the argv-overflow checking for a remote command that has a
 2387:       lot of args.
 2388: 
 2389:     - Use rsyserr() in the various places that were still calling rprintf()
 2390:       with strerror() as an arg.
 2391: 
 2392:     - If an rsync daemon is listening on multiple sockets (to handle both
 2393:       IPv4 and IPv6 to a single port), we now close all the unneeded file
 2394:       handles after we accept a connection (we used to close just one of
 2395:       them).
 2396: 
 2397:     - Optimized the handling of larger block sizes (rsync used to slow to a
 2398:       crawl if the block size got too large).
 2399: 
 2400:     - Optimized away a loop in hash_search().
 2401: 
 2402:     - Some improvements to the sanitize_path() and clean_fname() functions
 2403:       makes them more efficient and produce better results (while still
 2404:       being compatible with the file-name cleaning that gets done on both
 2405:       sides when sending the file-list).
 2406: 
 2407:     - Got rid of alloc_sanitize_path() after adding a destination-buffer
 2408:       arg to sanitize_path() made it possible to put all the former's
 2409:       functionality into the latter.
 2410: 
 2411:     - The file-list that is output when at least 4 verbose options are
 2412:       specified reports the uid value on the sender even when rsync is
 2413:       not running as root (since we might be sending to a root receiver).
 2414: 
 2415:   BUILD CHANGES:
 2416: 
 2417:     - Added a "gen" target to rebuild most of the generated files,
 2418:       including configure, config.h.in, the man pages, and proto.h.
 2419: 
 2420:     - If "make proto" doesn't find some changes in the prototypes, the
 2421:       proto.h file is left untouched (its time-stamp used to always be
 2422:       updated).
 2423: 
 2424:     - The variable $STRIP (that is optionally set by the install-strip
 2425:       target's rule) was changed to $INSTALL_STRIP because some systems
 2426:       have $STRIP already set in the environment.
 2427: 
 2428:     - Fixed a build problem when SUPPORT_HARD_LINKS isn't defined.
 2429: 
 2430:     - When cross-compiling, the gettimeofday() function is now assumed to
 2431:       be a modern version that takes two-args (since we can't test it).
 2432: 
 2433:   DEVELOPER RELATED:
 2434: 
 2435:     - The scripts in the testsuite dir were cleaned up a bit and a few
 2436:       new tests added.
 2437: 
 2438:     - Some new diffs were added to the patches dir, and some accepted
 2439:       ones were removed.

 2442: NEWS for rsync 2.6.2 (30 Apr 2004)
 2443: Protocol: 28 (unchanged)
 2444: Changes since 2.6.1:
 2445: 
 2446:   BUG FIXES:
 2447: 
 2448:     - Fixed a major bug in the sorting of the filenames when --relative
 2449:       is used for some sources (just sources such as "/" and "/*" were
 2450:       affected).  This fix ensures that we ask for the right file-list
 2451:       item when requesting changes from the sender.
 2452: 
 2453:     - Rsync now checks the return value of the close() function to
 2454:       better report disk-full problems on an NFS file system.
 2455: 
 2456:     - Restored the old daemon-server behavior of logging error messages
 2457:       rather than returning them to the user.  (A better long-term fix
 2458:       will be sought in the future.)
 2459: 
 2460:     - An obscure uninitialized-variable bug was fixed in the uid/gid
 2461:       code.  (This bug probably had no ill effects.)
 2462: 
 2463:   BUILD CHANGES:
 2464: 
 2465:     - Got rid of the configure check for sys/sysctl.h (it wasn't used
 2466:       and was causing a problem on some systems).  Also improved the
 2467:       broken-largefile-locking test to try to avoid failure due to an
 2468:       NFS build-dir.
 2469: 
 2470:     - Fixed a compile problem on systems that don't define
 2471:       AI_NUMERICHOST.
 2472: 
 2473:     - Fixed a compile problem in the popt source for compilers that
 2474:       don't support __attribute__.
 2475: 
 2476:   DEVELOPER RELATED:
 2477: 
 2478:     - Improved the testsuite's "merge" test to work on OSF1.
 2479: 
 2480:     - Two new diffs were added to the patches dir.
 2481: 
 2482: 
 2483: NEWS for rsync 2.6.1 (26 Apr 2004)
 2484: Protocol: 28 (changed)
 2485: Changes since 2.6.0:
 2486: 
 2487:   SECURITY FIXES:
 2488: 
 2489:     - Paths sent to an rsync daemon are more thoroughly sanitized when
 2490:       chroot is not used.  If you're running a non-read-only rsync
 2491:       daemon with chroot disabled, *please upgrade*, ESPECIALLY if the
 2492:       user privs you run rsync under is anything above "nobody".
 2493: 
 2494:   ENHANCEMENTS:
 2495: 
 2496:     - Lower memory use, more optimal transfer of data over the socket,
 2497:       and lower CPU usage (see the INTERNAL section for details).
 2498: 
 2499:     - The RSYNC_PROXY environment variable can now contain a
 2500:       "USER:PASS@" prefix before the "HOST:PORT" information.
 2501:       (Bardur Arantsson)
 2502: 
 2503:     - The --progress output now mentions how far along in the transfer
 2504:       we are, including both a count of files transferred and a
 2505:       percentage of the total file-count that we've processed.  It also
 2506:       shows better current-rate-of-transfer and remaining-transfer-time
 2507:       values.
 2508: 
 2509:     - Documentation changes now attempt to describe some often mis-
 2510:       understood features more clearly.
 2511: 
 2512:   BUG FIXES:
 2513: 
 2514:     - When -x (--one-file-system) is combined with -L (--copy-links) or
 2515:       --copy-unsafe-links, no symlinked files are skipped, even if the
 2516:       referent file is on a different filesystem.
 2517: 
 2518:     - The --link-dest code now works properly for a non-root user when
 2519:       (1) the UIDs of the source and destination differ and -o was
 2520:       specified, or (2) when the group of the source can't be used on
 2521:       the destination and -g was specified.
 2522: 
 2523:     - Fixed a bug in the handling of -H (hard-links) that might cause
 2524:       the expanded PATH/NAME value of the current item to get
 2525:       overwritten (due to an expanded-name caching bug).
 2526:       
 2527:     - We now reset the "new data has been sent" flag at the start of
 2528:       each file we send.  This makes sure that an interrupted transfer
 2529:       with the --partial option set doesn't keep a shorter temp file
 2530:       than the current basis file when no new data has been transferred
 2531:       over the wire for that file.
 2532: 
 2533:     - Fixed a byte-order problem in --batch-mode on big-endian machines.
 2534:       (Jay Fenlason)
 2535: 
 2536:     - When using --cvs-exclude, the exclude items we get from a
 2537:       per-directory's .cvsignore file once again only affect that one
 2538:       directory (not all following directories too).  The items are also
 2539:       now properly word-split and parsed without any +/- prefix parsing.
 2540: 
 2541:     - When specifying the USER@HOST: prefix for a file, the USER part
 2542:       can now contain an '@', if needed (i.e. the last '@' is used to
 2543:       find the HOST, not the first).
 2544: 
 2545:     - Fixed some bugs in the handling of group IDs for non-root users:
 2546:       (1) It properly handles a group that the sender didn't have a name
 2547:       for (it would previously skip changing the group on any files in
 2548:       that group).  (2) If --numeric-ids is used, rsync no longer
 2549:       attempts to set groups that the user doesn't have the permission
 2550:       to set.
 2551: 
 2552:     - Fixed the "refuse options" setting in the rsyncd.conf file.
 2553: 
 2554:     - Improved the -x (--one-file-system) flag's handling of any mount-
 2555:       point directories we encounter.  It is both more optimal (in that
 2556:       it no longer does a useless scan of the contents of the mount-
 2557:       point dirs) and also fixes a bug where a remapped mount of the
 2558:       original filesystem could get discovered in a subdir we should be
 2559:       ignoring.
 2560: 
 2561:     - Rsync no longer discards a double-slash at the start of a filename
 2562:       when trying to open the file.  It also no longer constructs names
 2563:       that start with a double slash (unless the user supplied them).
 2564: 
 2565:     - Path-specifying options to a daemon should now work the same with
 2566:       or without chroot turned on.  Previously, such a option (such as
 2567:       --link-dest) would get its absolute path munged into a relative
 2568:       one if chroot was not on, making that setting fairly useless.
 2569:       Rsync now transforms the path into one that is based on the
 2570:       module's base dir when chroot is not enabled.
 2571: 
 2572:     - Fixed a compatibility problem interacting with older rsync
 2573:       versions that might send us an empty --suffix value without
 2574:       telling us that --backup-dir was specified.
 2575: 
 2576:     - The "hosts allow" option for a daemon-over-remote-shell process
 2577:       now has improved support for IPv6 addresses and a fix for systems
 2578:       that have a length field in their socket structs.
 2579: 
 2580:     - Fixed the ability to request an empty backup --suffix when sending
 2581:       files to an rsync daemon.
 2582: 
 2583:     - Fixed an option-parsing bug when --files-from was sent to a server
 2584:       sender.
 2585: 
 2586:   INTERNAL:
 2587: 
 2588:     - Most of the I/O is now buffered, which results in a pretty large
 2589:       speedup when running under MS Windows.  (Craig Barratt)
 2590: 
 2591:     - Optimizations to the name-handling/comparing code have made some
 2592:       significant reductions in user-CPU time for large file sets.
 2593: 
 2594:     - Some cleanup of the variable types make the code more consistent.
 2595: 
 2596:     - Reduced memory requirements of hard link preservation.
 2597:       (J.W. Schultz)
 2598: 
 2599:     - Implemented a new algorithm for hard-link handling that speeds up
 2600:       the code significantly.  (J.W. Schultz and Wayne Davison)
 2601: 
 2602:     - The --hard-link option now uses the first existing file in the
 2603:       group of linked files as the basis for the transfer.  This
 2604:       prevents the sub-optimal transfer of a file's data when a new
 2605:       hardlink is added on the sending side and it sorts alphabetically
 2606:       earlier in the list than the files that are already present on the
 2607:       receiving side.
 2608: 
 2609:     - Dropped support for protocol versions less than 20 (2.3.0 released
 2610:       15 Mar 1999) and activated warnings for protocols less than 25
 2611:       (2.5.0 released 23 Aug 2001). (Wayne Davison and J.W. Schultz,
 2612:       severally)
 2613: 
 2614:     - More optimal data transmission for --hard-links (protocol 28).
 2615: 
 2616:     - More optimal data transmission for --checksum (protocol 28).
 2617: 
 2618:     - Less memory is used when --checksum is specified.
 2619: 
 2620:     - Less memory is used in the file list (a per-file savings).
 2621: 
 2622:     - The generator is now better about not modifying the file list
 2623:       during the transfer in order to avoid a copy-on-write memory
 2624:       bifurcation (on systems where fork() uses shared memory).
 2625:       Previously, rsync's shared memory would slowly become unshared,
 2626:       resulting in real memory usage nearly doubling on the receiving
 2627:       side by the end of the transfer.  Now, as long as permissions
 2628:       are being preserved, the shared memory should remain that way
 2629:       for the entire transfer.
 2630: 
 2631:     - Changed hardlink info and file_struct + strings to use allocation
 2632:       pools.  This reduces memory use for large file-sets and permits
 2633:       freeing memory to the OS.  (J.W. Schultz) 
 2634: 
 2635:     - The 2 pipes used between the receiver and generator processes
 2636:       (which are forked on the same machine) were reduced to 1 pipe and
 2637:       the protocol improved so that (1) it is now impossible to have the
 2638:       "redo" pipe fill up and hang rsync, and (2) trailing messages from
 2639:       the receiver don't get lost on their way through the generator
 2640:       over to the sender (which mainly affected hard-link messages and
 2641:       verbose --stats output).
 2642: 
 2643:     - Improved the internal uid/gid code to be more portable and a
 2644:       little more optimized.
 2645: 
 2646:     - The device numbers sent when using --devices are now sent as
 2647:       separate major/minor values with 32-bit accuracy (protocol 28).
 2648:       Previously, the copied devices were sent as a single 32-bit
 2649:       number.  This will make inter-operation of 64-bit binaries more
 2650:       compatible with their 32-bit brethren (with both ends of the
 2651:       connection are using protocol 28).  Note that optimizations in the
 2652:       binary protocol for sending the device numbers often results in
 2653:       fewer bytes being used than before, even though more precision is
 2654:       now available.
 2655: 
 2656:     - Some cleanup of the exclude/include structures and its code made
 2657:       things clearer (internally), simpler, and more efficient.
 2658: 
 2659:     - The reading & writing of the file-list in batch-mode is now
 2660:       handled by the same code that sends & receives the list over the
 2661:       wire.  This makes it much easier to maintain.  (Note that the
 2662:       batch code is still considered to be experimental.)
 2663: 
 2664:   BUILD CHANGES:
 2665: 
 2666:     - The configure script now accepts --with-rsyncd-conf=PATH to
 2667:       override the default value of the /etc/rsyncd.conf file.
 2668: 
 2669:     - Fixed configure bug when running "./configure --disable-ipv6".
 2670: 
 2671:     - Fixed compilation problem on Tru64 Unix (having to do with
 2672:       sockaddr.sa_len and sockaddr.sin_len).
 2673: 
 2674:   DEVELOPER RELATED:
 2675: 
 2676:     - Fixed "make test" bug when build dir is not the source dir.
 2677: 
 2678:     - Added a couple extra diffs in the "patches" dir, removed the ones
 2679:       that got applied, and rebuilt the rest.

 2682: NEWS for rsync 2.6.0 (1 Jan 2004)
 2683: Protocol: 27 (changed)
 2684: Changes since 2.5.7:
 2685: 
 2686:   ENHANCEMENTS:
 2687: 
 2688:     * "ssh" is now the default remote shell for rsync.  If you want to
 2689:       change this, configure like this:  "./configure --with-rsh=rsh".
 2690: 
 2691:     * Added --files-from, --no-relative, --no-implied-dirs, and --from0.
 2692:       Note that --from0 affects the line-ending character for all the
 2693:       files read by the --*-from options. (Wayne Davison)
 2694: 
 2695:     * Length of csum2 is now per-file starting with protocol version
 2696:       27. (J.W. Schultz)
 2697: 
 2698:     * Per-file dynamic block size is now sqrt(file length).  The
 2699:       per-file checksum size is determined according to an algorithm
 2700:       provided by Donovan Baarda which reduces the probability of rsync
 2701:       algorithm corrupting data and falling back using the whole md4
 2702:       checksums. (J.W. Schultz, Donovan Baarda)
 2703: 
 2704:     * The --stats option no longer includes the (debug) malloc summary
 2705:       unless the verbose option was specified at least twice.
 2706: 
 2707:     * Added a new error/warning code for when files vanish from the
 2708:       sending side.  Made vanished source files not interfere with the
 2709:       file-deletion pass when --delete-after was specified.
 2710: 
 2711:     * Various trailing-info sections are now preceded by a newline.
 2712: 
 2713:   BUG FIXES:
 2714: 
 2715:     * Fixed several exclude/include matching bugs when using wild-cards.
 2716:       This has a several user-visible effects, all of which make the
 2717:       matching more consistent and intuitive.  This should hopefully not
 2718:       cause anyone problems since it makes the matching work more like
 2719:       what people are expecting. (Wayne Davison)
 2720: 
 2721:       - A pattern with a "**" no longer causes a "*" to match slashes.
 2722:         For example, with "/*/foo/**", "foo" must be 2 levels deep.
 2723: 	[If your string has BOTH "*" and "**" wildcards, changing the
 2724: 	"*" wildcards to "**" will provide the old behavior in all
 2725: 	versions.]
 2726: 
 2727:       - "**/foo" now matches at the base of the transfer (like /foo
 2728:         does).  [Use "/**/foo" to get the old behavior in all versions.]
 2729: 
 2730:       - A non-anchored wildcard term floats to match beyond the base of
 2731:         the transfer.  E.g. "CVS/R*" matches at the end of the path,
 2732:         just like the non-wildcard term "CVS/Root" does. [Use "/CVS/R*"
 2733:         to get the old behavior in all versions.]
 2734: 
 2735:       - Including a "**" in the match term causes it to be matched
 2736:         against the entire path, not just the name portion, even if
 2737:         there aren't any interior slashes in the term.  E.g. "foo**bar"
 2738:         would exclude "/path/foo-bar" (just like before) as well as
 2739:         "/foo-path/baz-bar" (unlike before).  [Use "foo*bar" to get the
 2740:         old behavior in all versions.]
 2741: 
 2742:     * The exclude list specified in the daemon's config file is now
 2743:       properly applied to the pulled items no matter how deep the
 2744:       user's file-args are in the source tree.  (Wayne Davison)
 2745: 
 2746:     * For protocol version >= 27, mdfour_tail() is called when the
 2747:       block size (including checksum_seed) is a multiple of 64.
 2748:       Previously it was not called, giving the wrong MD4 checksum.
 2749:       (Craig Barratt)
 2750: 
 2751:     * For protocol version >= 27, a 64 bit bit counter is used in
 2752:       mdfour.c as required by the RFC.  Previously only a 32 bit bit
 2753:       counter was used, causing incorrect MD4 file checksums for
 2754:       file sizes >= 512MB - 4.  (Craig Barratt)
 2755: 
 2756:     * Fixed a crash bug when interacting with older rsync versions and
 2757:       multiple files of the same name are destined for the same dir.
 2758:       (Wayne Davison)
 2759: 
 2760:     * Keep tmp names from overflowing MAXPATHLEN.
 2761: 
 2762:     * Make --link-dest honor the absence of -p, -o, and -g.
 2763: 
 2764:     * Made rsync treat a trailing slash in the destination in a more
 2765:       consistent manner.
 2766: 
 2767:     * Fixed file I/O error detection.  (John Van Essen)
 2768: 
 2769:     * Fixed bogus "malformed address {hostname}" message in rsyncd log
 2770:       when checking IP address against hostnames from "hosts allow"
 2771:       and "hosts deny" parameters in config file.
 2772: 
 2773:     * Print heap statistics when verbose >= 2 instead of when >= 1.
 2774: 
 2775:     * Fixed a compression (-z) bug when syncing a mostly-matching file
 2776:       that contains already-compressed data.  (Yasuoka Masahiko and
 2777:       Wayne Davison)
 2778: 
 2779:     * Fixed a bug in the --backup code that could cause deleted files
 2780:       to not get backed up.
 2781: 
 2782:     * When the backup code makes new directories, create them with mode
 2783:       0700 instead of 0755 (since the directory permissions in the
 2784:       backup tree are not yet copied from the main tree).
 2785: 
 2786:     * Call setgroups() in a more portable manner.
 2787: 
 2788:     * Improved file-related error messages to better indicate exactly
 2789:       what pathname failed. (Wayne Davison)
 2790: 
 2791:     * Fixed some bugs in the handling of --delete and --exclude when
 2792:       using the --relative (-R) option. (Wayne Davison)
 2793: 
 2794:     * Fixed bug that prevented regular files from replacing
 2795:       special files and caused a directory in --link-dest or
 2796:       --compare-dest to block the creation of a file with the
 2797:       same path.  A directory still cannot be replaced by a
 2798:       regular file unless --delete specified.  (J.W. Schultz)
 2799: 
 2800:     * Detect and report when open or opendir succeed but read and
 2801:       readdir fail caused by network filesystem issues and truncated
 2802:       files.  (David Norwood, Michael Brown, J.W. Schultz)
 2803: 
 2804:     * Added a fix that should give ssh time to restore the tty settings
 2805:       if the user presses Ctrl-C at an ssh password prompt.
 2806: 
 2807:   INTERNAL:
 2808: 
 2809:     * Eliminated vestigial support for old versions that we stopped
 2810:       supporting. (J.W. Schultz)
 2811: 
 2812:     * Simplified some of the option-parsing code. (Wayne Davison)
 2813: 
 2814:     * Some cleanup made to the exclude code, as well as some new
 2815:       defines added to enhance readability. (Wayne Davison)
 2816: 
 2817:     * Changed the protocol-version code so that it can interact at a
 2818:       lower protocol level than the maximum supported by both sides.
 2819:       Added an undocumented option, --protocol=N, to force the value
 2820:       we advertise to the other side (primarily for testing purposes).

 2837: 
 2838:   ENHANCEMENTS:
 2839: 
 2840:     * The --delete-after option now implies --delete.  (Wayne Davison)
 2841: 
 2842:     * The --suffix option can now be used with --backup-dir.  (Michael
 2843:       Zimmerman)
 2844: 
 2845:     * Combining "::" syntax with the --rsh/-e option now uses the
 2846:       specified remote-shell as a transport to talk to a (newly-spawned)
 2847:       server-daemon.  This allows someone to use daemon features, such
 2848:       as modules, over a secure protocol, such as ssh.  (JD Paul)

 2859:

 2868: 
 2869:     * Changed exclude file handling to permit DOS or MAC style line

 2878:       L. Allen, Martin Pool)
 2879: 
 2880:     * Generate each file's rolling-checksum data as we send it, not

 2887: 
 2888:     * Fixed a crash that would occur when sending a list of files that

 3007:       "unsigned int64" in rsync.h.
 3008: 
 3009:     * Fixed problem on systems such as Sunos4 that do not support realloc
 3010:       on a NULL pointer; error was "out of memory in flist_expand".
 3011: 
 3012:     * Fix for rsync server processes hanging around after the client
 3013:       unexpectedly disconnects.  (Colin Walters) (Debian bug #128632)
 3014: 
 3015:     * Cope with BSD systems on which mkdir() will not accept a trailing
 3016:       slash.
 3017: 
 3018:   ENHANCEMENTS:
 3019: 
 3020:     * Merge in changes from zlib 1.1.2 to zlib 1.1.3.  (Note that
 3021:       rsync still uses a custom version of zlib; you can not just link
 3022:       against a system library.  See zlib/README.rsync)
 3023: 
 3024:     * Command to initiate connections is only shown with -vv, rather
 3025:       than -v as in 2.5.2.  Output from plain -v is more similar to
 3026:       what was historically used so as not to break scripts that try
 3027:       to parse the output.
 3028: 
 3029:     * Added --no-whole-file and --no-blocking-io options (Dave Dykstra)
 3030: 
 3031:     * Made the --write-batch and --read-batch options actually work
 3032:       and added documentation in the man page (Jos Backus)
 3033: 
 3034:     * If the daemon is unable to fork a child to accept a connection,
 3035:       print an error message.  (Colin Walters)

 3039: Protocol: 26 (changed)
 3040: Changes since 2.5.1:
 3041: 
 3042:   SECURITY FIXES:
 3043: 
 3044:     * Signedness security patch from Sebastian Krahmer
 3045:       <krahmer@suse.de> -- in some cases we were not sufficiently
 3046:       careful about reading integers from the network.
 3047: 
 3048:   BUG FIXES:
 3049: 
 3050:     * Fix possible string mangling in log files.
 3051: 
 3052:     * Fix for setting local address of outgoing sockets.
 3053: 
 3054:     * Better handling of hardlinks and devices on platforms with
 3055:       64-bit dev_t or ino_t.
 3056: 
 3057:     * Name resolution on machines supporting IPv6 is improved.
 3058: 
 3059:     * Fix for device nodes.  (dann frazier)   (Debian #129135)
 3060: 
 3061:   ENHANCEMENTS:
 3062: 
 3063:     * With -v, rsync now shows the command used to initiate an ssh/rsh
 3064:       connection.
 3065: 
 3066:     * --statistics now shows memory heap usage on platforms that
 3067:       support mallinfo().
 3068: 
 3069:     * "The Ted T'so school of program optimization": make progress
 3070:       visible and people will think it's faster.  (With --progress,
 3071:       rsync will show you how many files it has seen as it builds the
 3072:       file_list, giving some indication that it has not hung.)
 3073: 
 3074:     * Improvements to batch mode support.  This is still experimental
 3075:       but testing would be welcome.   (Jos Backus)
 3076: 
 3077:     * New --ignore-existing option, patch previously distributed with
 3078:       Vipul's Razor.  (Debian #124286)

 3083: Changes since 2.5.0:
 3084: 
 3085:   BUG FIXES:
 3086: 
 3087:     * Fix for segfault in --daemon mode configuration parser.  (Paul
 3088:       Mackerras)
 3089: 
 3090:     * Correct string<->address parsing for both IPv4 and 6.
 3091:       (YOSHIFUJI Hideaki, SUMIKAWA Munechika and Jun-ichiro "itojun"
 3092:       Hagino)
 3093: 
 3094:     * Various fixes for IPv6 support.  (Dave Dykstra)
 3095: 
 3096:     * rsync.1 typo fix.  (Matt Kraai)
 3097: 
 3098:     * Test suite typo fixes.  (Tom Schmidt)
 3099: 
 3100:     * rsync.1 grammar and clarity improvements.  (Edward
 3101:       Welbourne)
 3102: 
 3103:     * Correction to ./configure tests for inet_ntop.  (Jeff Garzik)
 3104: 
 3105:   ENHANCEMENTS:
 3106: 
 3107:     * --progress and -P now show estimated data transfer rate (in a
 3108:       multiple of bytes/s) and estimated time to completion.  (Rik
 3109:       Faith)
 3110: 
 3111:     * --no-detach option, required to run as a W32 service and also
 3112:       useful when running on Unix under daemontools, AIX's SRC, or a
 3113:       debugger.  (Max Bowsher, Jos Backus)
 3114: 
 3115:     * Clearer error messages for some conditions.

 3118: NEWS for rsync 2.5.0 (30 Nov 2001)
 3119: Protocol: 25 (changed)
 3120: Changes since 2.4.6:
 3121: 
 3122:   ANNOUNCEMENTS
 3123: 
 3124:     * Martin Pool <mbp@samba.org> is now a co-maintainer.
 3125: 
 3126:   NEW FEATURES
 3127: 
 3128:     * Support for LSB-compliant packaging <http://www.linuxbase.org/>
 3129: 
 3130:     * Shell wildcards are allowed in "auth users" lines.
 3131: 
 3132:     * Merged UNC rsync+ patch to support creation of standalone patch
 3133:       sets.  By Bert J. Dempsey and Debra Weiss, updated by Jos
 3134:       Backus.  <http://www.ils.unc.edu/i2dsi/unc_rsync+.html>
 3135: 
 3136:     * IPv6 support based on a patch from KAME.net, on systems
 3137:       including modern versions of Linux, Solaris, and HP-UX.  Also
 3138:       includes IPv6 compatibility functions for old OSs by the
 3139:       Internet Software Consortium, Paul Vixie, the OpenSSH
 3140:       portability project, and OpenBSD.
 3141: 
 3142:   ENHANCEMENTS
 3143: 
 3144:     * Include/exclude cluestick: with -vv, print out whether files are
 3145:       included or excluded and why.
 3146: 
 3147:     * Many error messages have more friendly explanations and more
 3148:       details.
 3149: 
 3150:     * Manual page improvements plus scanty protocol documentation.
 3151: 
 3152:     * When running as --daemon in the background and using a "log
 3153:       file" rsyncd.conf directive, close the log file every time it is
 3154:       open when going to sleep on the socket.  This allows the log
 3155:       file to get cleaned out by another process.
 3156: 
 3157:     * Change to using libpopt rather than getopt for processing
 3158:       options.	This makes the code cleaner and the behaviour more
 3159:       consistent across platforms.  popt is included and built if not
 3160:       installed on the platform.
 3161: 
 3162:     * More details in --version, including note about whether 64-bit
 3163:       files, symlinks and hardlinks are supported.
 3164: 
 3165:     * MD4 code may use less CPU cycles.
 3166: 
 3167:     * Use mkstemp on systems where it is secure.  If we use mktemp,
 3168:       explain that we do it in a secure way.
 3169: 
 3170:     * --whole-file is the default when source and target are on the
 3171: 	local machine.
 3172: 
 3173:   BUG FIXES:
 3174: 
 3175:     * Fix for various bugs causing rsync to hang.
 3176: 
 3177:     * Attempt to fix Large File Summit support on AIX.
 3178: 
 3179:     * Attempt to fix error handling lockup bug.
 3180: 
 3181:     * Give a non-0 exit code if *any* of the files we have been asked
 3182:       to transfer fail to transfer.
 3183: 
 3184:     * For log messages containing ridiculously long strings that might
 3185:       overflow a buffer rsync no longer aborts, but rather prints an
 3186:       ellipsis at the end of the string.  (Patch from Ed Santiago.)
 3187: 
 3188:   PLATFORMS:
 3189: 
 3190:     * Improved support for UNICOS (tested on Cray T3E and Cray SV1)
 3191: 
 3192:     * autoconf2.52 (or later) is now required to rebuild the autoconf
 3193:       scripts.  It is not required to simply build rsync.
