-NEWS for rsync version 2.6.0
-Protocol: 27 (changed)
-Changes since version 2.5.7:
+NEWS for rsync 2.6.3 (30 Sep 2004)
+Protocol: 28 (unchanged)
+Changes since 2.6.2:
 
-  ENHANCEMENTS:
+  SECURITY FIXES:
 
-    * "ssh" is now the default remote shell for rsync.  If you want to
-      change this, configure like this:  "./configure --with-rsh=rsh".
+    - A bug in the sanitize_path routine (which affects a non-chrooted
+      rsync daemon) could allow a user to craft a pathname that would get
+      transformed into an absolute path for certain options (but not for
+      file-transfer names).  If you're running an rsync daemon with chroot
+      disabled, *please upgrade*, ESPECIALLY if the user privs you run
+      rsync under is anything above "nobody".
 
-    * Added --files-from, --no-relative, --no-implied-dirs, and --from0.
-      Note that --from0 affects the line-ending character for all the
-      files read by the --*-from options. (Wayne Davison)
+  OUTPUT CHANGES (ATTN: those using a script to parse the verbose output):
 
-    * Length of csum2 is now per-file starting with protocol verison
-      27. (J.W. Schultz)
+    - Please note that the 2-line footer (output when verbose) now uses the
+      term "sent" instead of "wrote" and "received" instead of "read".  If
+      you are not parsing the numeric values out of this footer, a script
+      would be better off using the empty line prior to the footer as the
+      indicator that the verbose output is over.
+      
+    - The output from the --stats option was similarly affected to change
+      "written" to "sent" and "read" to "received".
 
-    * Per-file dynamic block size is now sqrt(file length).
-      The per-file checksum size is determined according
-      to an algorythm provided by Donovan Baarda which
-      reduces the probability of rsync algorithm
-      corrupting data and falling back using the whole md4
-      checksums. (J.W. Schultz, Donovan Baarda)
+    - Rsync ensures that a filename that contains a newline gets mentioned
+      with each newline transformed into a question mark (which prevents a
+      filename from causing an empty line to be output).
 
-    * The --stats option no longer includes the (debug) malloc summary
-      unless the verbose option was specified at least twice.
-
-    * Added a new error/warning code for when files vanish from the
-      sending side.  Made vanished source files not interfere with the
-      file-deletion pass when --delete-after was specified.
+    - The "backed up ..." message that is output when at least 2 --verbose
+      options are specified is now the same both with and without the
+      --backup-dir option.
 
   BUG FIXES:
 
-    * Fixed several exclude/include matching bugs when using wild-cards.
-      This has a several user-visible effects, all of which make the
-      matching more consistent and intuitive.  This should hopefully not
-      cause anyone problems since it makes the matching work more like
-      what people are expecting. (Wayne Davison)
+    - Fixed a crash bug that might appear when --delete was used and
+      multiple source directories were specified.
 
-      - A pattern with a "**" no longer causes a "*" to match slashes.
-        For example, with "/*/foo/**", "foo" must be 2 levels deep.
+    - Fixed a 32-bit truncation of the file length when generating the
+      checksums.
 
-      - "**/foo" now matches at the base of the transfer (i.e. /foo).
+    - The --backup code no longer attempts to create some directories
+      over and over again (generating warnings along the way).
 
-      - An non-anchored wildcard term floats to match beyond the base of
-        the transfer.  E.g. "CVS/R*" matches at the end of the path,
-        just like the non-wildcard term "CVS/Root" does.
+    - Fixed a bug in the reading of the secrets file (by the daemon) and
+      the password file (by the client):  the files no longer need to be
+      terminated by a newline for their content to be read in.
 
-      - Including a "**" in the match term causes it to be matched
-        against the entire path, not just the name portion, even if
-        there aren't any interior slashes in the term.  E.g. "foo**bar"
-        would exclude "/path/foo-bar" (just like before) as well as
-        "/foo-path/baz-bar" (for instance).
+    - If a file has a read error on the sending side or the reconstructed
+      data doesn't match the expected checksum (perhaps due to the basis
+      file changing during the transfer), the receiver will no longer
+      retain the resulting file unless the --partial option was specified.
+      (Note: for the read-error detection to work, neither side can be
+      older than 2.6.3 -- older receivers will always retain the file, and
+      older senders don't tell the receiver that the file had a read
+      error.)
 
-    * The exclude list specified in the daemon's config file is now
-      properly applied to the pulled items no matter how deep the
-      user's file-args are in the source tree.  (Wayne Davison)
+    - If a file gets resent in a single transfer and the --backup option
+      is enabled, rsync no longer performs a duplicate backup (it used to
+      overwrite the original file in the backup area).
 
-    * For protocol version >= 27, mdfour_tail() is called when the
-      block size (including checksum_seed) is a multiple of 64.
-      Previously it was not called, giving the wrong MD4 checksum.
-      (Craig Barratt)
-  
-    * For protocol version >= 27, a 64 bit bit counter is used in
-      mdfour.c as required by the RFC.  Previously only a 32 bit bit
-      counter was used, causing incorrect MD4 file checksums for
-      file sizes >= 512MB - 4.  (Craig Barratt)
+    - Files specified in the daemon's "exclude" or "exclude from" config
+      items are now excluded from being uploaded (assuming that the module
+      allows uploading at all) in addition to the old download exclusion.
 
-    * Fixed a crash bug when interacting with older rsync versions and
-      multiple files of the same name are destined for the same dir.
-      (Wayne Davison)
+    - Got rid of a potential hang in the receiver when near the end of a
+      phase.
 
-    * Keep tmp names from overflowing MAXPATHLEN.
+    - When using --backup without a --backup-dir, rsync no longer preserves
+      the modify time on directories.  This avoids confusing NFS.
 
-    * Make --link-dest honor the absence of -p, -o, and -g.
+    - When --copy-links (-L) is specified, we now output a separate error
+      for a symlink that has no referent instead of claiming that a file
+      "vanished".
 
-    * Made rsync treat a trailing slash in the destination in a more
-      consistent manner.
+    - The --copy-links (-L) option no longer has the side-effect of telling
+      the receiving side to follow symlinks.  See the --keep-dirlinks
+      option (mentioned below) for a way to specify that behavior.
 
-    * Fixed file I/O error detection.  (John Van Essen)
+    - Error messages from the daemon server's option-parsing (such as
+      refused options) are now successfully transferred back to the client
+      (the server used to fail to send the message because the socket
+      wasn't in the right state for the message to get through).
 
-    * Fixed a compression (-z) bug when syncing a mostly-matching file
-      that contains already-compressed data.  (Yasuoka Masahiko and
-      Wayne Davison)
+    - Most transfer errors that occur during a daemon transfer are now
+      returned to the user in addition to being logged (some messages are
+      intended to be daemon-only and are not affected by this).
 
-    * Fixed a bug in the --backup code that could cause deleted files
-      to not get backed up.
+    - Fixed a bug in the daemon authentication code when using one of the
+      batch-processing options.
 
-    * Call setgroups() in a more portable manner.
+    - We try to work around some buggy IPv6 implementations that fail to
+      implement IPV6_V6ONLY.  This should fix the "address in use" error
+      that some daemons get when running on an OS with a buggy IPv6
+      implementation.  Also, if the new code gets this error, we might
+      suggest that the user specify --ipv4 or --ipv6 (if we think it will
+      help).
 
-    * Improved file-related error messages to better indicate exactly
-      what pathname failed. (Wayne Davison)
+    - When the remote rsync dies, make a better effort to recover any error
+      messages it may have sent before dying (the local rsync used to just
+      die with a socket-write error).
 
-    * Fixed some bugs in the handling of --delete and --exclude when
-      using the --relative (-R) option. (Wayne Davison)
+    - When using --delete and a --backup-dir that contains files that are
+      hard-linked to their destination equivalents, rsync now makes sure
+      that removed files really get removed (avoids a really weird rename()
+      behavior).
 
-    * Fixed bug that prevented regular files from replacing
-      special files and caused a directory in --link-dest or
-      --compare-dest to block the creation of a file with the
-      same path.  A directory still cannot be replaced by a
-      regular file unless --delete specified.  (J.W. Schultz)
+    - Avoid a bogus run-time complaint about a lack of 64-bit integers when
+      the int64 type is defined as an off_t and it actually has 64-bits.
 
-    * Detect and report when open or opendir succeed but read and
-      readdir fail caused by network filesystems issues and truncated
-      files.  (David Norwood, Michael Brown, J.W. Schultz)
+    - Added a configure check for open64() without mkstemp64() so that we
+      can avoid using mkstemp() when such a combination is encountered.
+      This bypasses a problem writing out large temp files on OSes such as
+      AIX and HP-UX.
 
-    * Added a fix that should give ssh time to restore the tty settings
-      if the user presses Ctrl-C at an ssh password prompt.
+    - Fixed an age-old crash problem with --read-batch on a local copy
+      (rsync was improperly assuming --whole-file for the local copy).
 
-  INTERNAL:
+    - When --dry-run (-n) is used and the destination directory does not
+      exist, rsync now produces a correct report of files that would be
+      sent instead of dying with a chdir() error.
 
-    * Eliminated vestigial support for old versions that we stopped
-      supporting. (J.W. Schultz)
+    - Fixed a bug that could cause a slow-to-connect rsync daemon to die
+      with an error instead of waiting for the connection to finish.
 
-    * Simplified some of the option-parsing code. (Wayne Davison)
-
-    * Some cleanup made to the exclude code, as well as some new
-      defines added to enhance readability. (Wayne Davison)
-
-    * Changed the protocol-version code so that it can interact at a
-      lower protocol level than the maximum supported by both sides.
-      Added an undocumented option, --protocol=N, to force the value
-      we advertise to the other side (primarily for testing purposes).
-      (Wayne Davison)

-NEWS for rsync version 2.5.6, aka the dwd-between-jobs release
-Protocol: 26 (unchanged)
-Changes since version 2.5.5:
+    - Fixed an ssh interaction that could cause output to be lost when the
+      user chose to combine the output of rsync's stdout and stderr (e.g.
+      using the "2>&1").
 
   ENHANCEMENTS:
 
-    * The --delete-after option now implies --delete.  (Wayne Davison)
+    - Added the --partial-dir=DIR option that lets you specify where to
+      (temporarily) put a partially transferred file (instead of over-
+      writing the destination file).  E.g.  --partial-dir=.rsync-partial
+      Also added support for the RSYNC_PARTIAL_DIR environment variable
+      that, when found, transforms a regular --partial option (such as
+      the convenient -P option) into one that also specifies a directory.
 
-    * The --suffix option can now be used with --backup-dir.  (Michael
-      Zimmerman)
+    - Added --keep-dirlinks (-K), which allows you to symlink a directory
+      onto another partition on the receiving side and have rsync treat it
+      as matching a normal directory from the sender.
 
-    * Combining "::" syntax with the -rsh/-e option now uses the
-      specified remote-shell as a transport to talk to a (newly-spawned)
-      server-daemon.  This allows someone to use daemon features, such
-      as modules, over a secure protocol, such as ssh.  (JD Paul)
+    - Added the --inplace option that tells rsync to write each destination
+      file without using a temporary file.  The matching of existing data
+      in the destination file can be severely limited by this, but there
+      are also cases where this is more efficient (such as appending data).
+      Use only when needed (see the man page for more details).
 
-    * The rsync:// syntax for daemon connections is now accepted in the
-      destination field.
+    - Added the "write only" option for the daemon's config file.
 
-    * If the file name given to --include-from or --exclude-from is "-",
-      rsync will read from standard input.  (J.W. Schultz)
+    - Added long-option names for -4 and -6 (namely --ipv4 and --ipv6)
+      and documented all these options in the man page.
 
-    * New option --link-dest which is like --compare-dest except that
-      unchanged files are hard-linked in to the destination directory.
-      (J.W. Schultz)
+    - Improved the handling of the --bwlimit option so that it's less
+      bursty, more accurate, and works properly over a larger range of
+      values.
 
-    * Don't report an error if an excluded file disappears during an
-      rsync run.  (Eugene Chupriyanov and Bo Kersey)
+    - The rsync daemon-over-ssh code now looks for SSH_CONNECTION and
+      SSH2_CLIENT in addition to SSH_CLIENT to figure out the IP address.
 
-    * Added .svn to --cvs-exclude list to support subversion.  (Jon
-      Middleton)
+    - Added the --checksum-seed=N option for advanced users.
 
-    * Properly support IPv6 addresses in the rsyncd.conf "hosts allow"
-      and "hosts deny" fields.  (Hideaki Yoshifuji)
+    - Batch writing/reading has a brand-new implementation that is simpler,
+      fixes a few weird problems with the old code (such as no longer
+      sprinkling the batch files into different dirs or even onto different
+      systems), and is much less intrusive into the code (making it easier
+      to maintain for the future).  The new code generates just one data
+      file instead of three, which makes it possible to read the batch on
+      stdin via a remote shell.  Also, the old requirement of forcing the
+      same fixed checksum-seed for all batch processing has been removed.
 
-    * Changed exclude file handling to permit DOS or MAC style line
-      terminations.  (J.W. Schultz)
+    - If an rsync daemon has a module set with "list = no" (which hides its
+      presence in the list of available modules), a user that fails to
+      authenticate gets the same "unknown module" error that they would get
+      if the module were actually unknown (while still logging the real
+      error to the daemon's log file).  This prevents fishing for module
+      names.
 
-    * Ignore errors from chmod when -p/-a/--preserve-perms is not set.
-      (Dave Dykstra)
+    - The daemon's "refuse options" config item now allows you to match
+      option names using wildcards and/or the single-letter option names.
 
-  BUG FIXES:
+    - Each transferred file now gets its permissions and modified-time
+      updated before the temp-file gets moved into place.  Previously, the
+      finished file would have a very brief window where its permissions
+      disallowed all group and world access.
 
-    * Fix "forward name lookup failed" errors on AIX 4.3.3.  (John
-      L. Allen, Martin Pool)
+    - Added the ability to parse a literal IPv6 address in an "rsync:" URL
+      (e.g. rsync://[2001:638:500:101::21]:873/module/dir).
 
-    * Generate each file's rolling-checksum data as we send it, not
-      in a separate (memory-eating) pass before hand.  This prevents
-      timeout errors on really large files. (Stefan Nehlsen)
-
-    * Fix compilation on Tru64.  (Albert Chin, Zoong Pham)
-
-    * Better handling of some client-server errors.  (Martin Pool)
-
-    * Fixed a crash that would occur when sending a list of files that
-      contains a duplicate name (if it sorts to the end of the file
-      list) and using --delete.  (Wayne Davison)
-
-    * Fixed the file-name duplicate-removal code when dealing with multiple
-      dups in a row. (Wayne Davison)
-
-    * Fixed a bug that caused rsync to lose the exit status of its child
-      processes and sometimes return an exit code of 0 instead of showing
-      an error.  (David R. Staples, Dave Dykstra)
-
-    * Fixed bug in --copy-unsafe-links that caused it to be completely
-      broken.  (Dave Dykstra)
-
-    * Prevent infinite recursion in cleanup code under certain circumstances.
-      (Sviatoslav Sviridov and Marc Espie)
-
-    * Fixed a bug that prevented rsync from creating intervening directories
-      when --relative-paths/-R is set.  (Craig Barratt)
-
-    * Prevent "Connection reset by peer" messages from Cygwin. (Randy O'Meara)
+    - The daemon's wildcard expanding code can now handle more than 1000
+      filenames (it's now limited by memory instead of having a hard-wired
+      limit).
 
   INTERNAL:
 
-    * Many code cleanups and improved internal documentation.  (Martin
-      Pool, Nelson Beebe)
+    - Some cleanup in the exclude code has saved some per-exclude memory
+      and made the code easier to maintain.
 
-    * Portability fixes. (Dave Dykstra and Wayne Davison)
+    - Improved the argv-overflow checking for a remote command that has a
+      lot of args.
 
-    * More test cases.  (Martin Pool)
+    - Use rsyserr() in the various places that were still calling rprintf()
+      with strerror() as an arg.
 
-    * Some test-case fixes.  (Brian Poole, Wayne Davison)
+    - If an rsync daemon is listening on multiple sockets (to handle both
+      IPv4 and IPv6 to a single port), we now close all the unneeded file
+      handles after we accept a connection (we used to close just one of
+      them).
 
-    * Updated included popt to the latest vendor drop, version 1.6.4.
-      (Jos Backus)
+    - Optimized the handling of larger block sizes (rsync used to slow to a
+      crawl if the block size got too large).
+
+    - Optimized away a loop in hash_search().
+
+    - Some improvements to the sanitize_path() and clean_fname() functions
+      makes them more efficient and produce better results (while still
+      being compatible with the file-name cleaning that gets done on both
+      sides when sending the file-list).
+
+    - Got rid of alloc_sanitize_path() after adding a destination-buffer
+      arg to sanitize_path() made it possible to put all the former's
+      functionality into the latter.
+
+    - The file-list that is output when at least 4 verbose options are
+      specified reports the uid value on the sender even when rsync is
+      not running as root (since we might be sending to a root receiver).
+
+  BUILD CHANGES:
+
+    - Added a "gen" target to rebuild most of the generated files,
+      including configure, config.h.in, the man pages, and proto.h.
+
+    - If "make proto" doesn't find some changes in the prototypes, the
+      proto.h file is left untouched (its time-stamp used to always be
+      updated).
+
+    - The variable $STRIP (that is optionally set by the install-strip
+      target's rule) was changed to $INSTALL_STRIP because some systems
+      have $STRIP already set in the environment.
+
+    - Fixed a build problem when SUPPORT_HARD_LINKS isn't defined.
+
+    - When cross-compiling, the gettimeofday() function is now assumed to
+      be a modern version that takes two-args (since we can't test it).
+
+  DEVELOPER RELATED:
+
+    - The scripts in the testsuite dir were cleaned up a bit and a few
+      new tests added.
+
+    - Some new diffs were added to the patches dir, and some accepted
+      ones were removed.
 
-    * Updated config.guess and config.sub to latest versions; this
-      means rsync should build on more platforms.  (Paul Green)

-rsync 2.5.5 "Snowy River" (2 April 2002)
-protocol: 26 (unchanged)
+NEWS for rsync 2.6.2 (30 Apr 2004)
+Protocol: 28 (unchanged)
+Changes since 2.6.1:
+
+  BUG FIXES:
+
+    - Fixed a major bug in the sorting of the filenames when --relative
+      is used for some sources (just sources such as "/" and "/*" were
+      affected).  This fix ensures that we ask for the right file-list
+      item when requesting changes from the sender.
+
+    - Rsync now checks the return value of the close() function to
+      better report disk-full problems on an NFS file system.
+
+    - Restored the old daemon-server behavior of logging error messages
+      rather than returning them to the user.  (A better long-term fix
+      will be sought in the future.)
+
+    - An obscure uninitialized-variable bug was fixed in the uid/gid
+      code.  (This bug probably had no ill effects.)
+
+  BUILD CHANGES:
+
+    - Got rid of the configure check for sys/sysctl.h (it wasn't used
+      and was causing a problem on some systems).  Also improved the
+      broken-largefile-locking test to try to avoid failure due to an
+      NFS build-dir.
+
+    - Fixed a compile problem on systems that don't define
+      AI_NUMERICHOST.
+
+    - Fixed a compile problem in the popt source for compilers that
+      don't support __attribute__.
+
+  DEVELOPER RELATED:
+
+    - Improved the testsuite's "merge" test to work on OSF1.
+
+    - Two new diffs were added to the patches dir.

+NEWS for rsync 2.6.1 (26 Apr 2004)
+Protocol: 28 (changed)
+Changes since 2.6.0:
+
+  SECURITY FIXES:
+
+    - Paths sent to an rsync daemon are more thoroughly sanitized when
+      chroot is not used.  If you're running a non-read-only rsync
+      daemon with chroot disabled, *please upgrade*, ESPECIALLY if the
+      user privs you run rsync under is anything above "nobody".
+
+  ENHANCEMENTS:
+
+    - Lower memory use, more optimal transfer of data over the socket,
+      and lower CPU usage (see the INTERNAL section for details).
+
+    - The RSYNC_PROXY environment variable can now contain a
+      "USER:PASS@" prefix before the "HOST:PORT" information.
+      (Bardur Arantsson)
+
+    - The --progress output now mentions how far along in the transfer
+      we are, including both a count of files transferred and a
+      percentage of the total file-count that we've processed.  It also
+      shows better current-rate-of-transfer and remaining-transfer-time
+      values.
+
+    - Documentation changes now attempt to describe some often mis-
+      understood features more clearly.
+
+  BUG FIXES:
+
+    - When -x (--one-file-system) is combined with -L (--copy-links) or
+      --copy-unsafe-links, no symlinked files are skipped, even if the
+      referent file is on a different filesystem.
+
+    - The --link-dest code now works properly for a non-root user when
+      (1) the UIDs of the source and destination differ and -o was
+      specified, or (2) when the group of the source can't be used on
+      the destination and -g was specified.
+
+    - Fixed a bug in the handling of -H (hard-links) that might cause
+      the expanded PATH/NAME value of the current item to get
+      overwritten (due to an expanded-name caching bug).
+      
+    - We now reset the "new data has been sent" flag at the start of
+      each file we send.  This makes sure that an interrupted transfer
+      with the --partial option set doesn't keep a shorter temp file
+      than the current basis file when no new data has been transfered
+      over the wire for that file.
+
+    - Fixed a byte-order problem in --batch-mode on big-endian machines.
+      (Jay Fenlason)
+
+    - When using --cvs-exclude, the exclude items we get from a
+      per-directory's .cvsignore file once again only affect that one
+      directory (not all following directories too).  The items are also
+      now properly word-split and parsed without any +/- prefix parsing.
+
+    - When specifying the USER@HOST: prefix for a file, the USER part
+      can now contain an '@', if needed (i.e. the last '@' is used to
+      find the HOST, not the first).
+
+    - Fixed some bugs in the handling of group IDs for non-root users:
+      (1) It properly handles a group that the sender didn't have a name
+      for (it would previously skip changing the group on any files in
+      that group).  (2) If --numeric-ids is used, rsync no longer
+      attempts to set groups that the user doesn't have the permission
+      to set.
+
+    - Fixed the "refuse options" setting in the rsyncd.conf file.
+
+    - Improved the -x (--one-file-system) flag's handling of any mount-
+      point directories we encounter.  It is both more optimal (in that
+      it no longer does a useless scan of the contents of the mount-
+      point dirs) and also fixes a bug where a remapped mount of the
+      original filesystem could get discovered in a subdir we should be
+      ignoring.
+
+    - Rsync no longer discards a double-slash at the start of a filename
+      when trying to open the file.  It also no longer constructs names
+      that start with a double slash (unless the user supplied them).
+
+    - Path-specifying options to a daemon should now work the same with
+      or without chroot turned on.  Previously, such a option (such as
+      --link-dest) would get its absolute path munged into a relative
+      one if chroot was not on, making that setting fairly useless.
+      Rsync now transforms the path into one that is based on the
+      module's base dir when chroot is not enabled.
+
+    - Fixed a compatibility problem interacting with older rsync
+      versions that might send us an empty --suffix value without
+      telling us that --backup-dir was specified.
+
+    - The "hosts allow" option for a daemon-over-remote-shell process
+      now has improved support for IPv6 addresses and a fix for systems
+      that have a length field in their socket structs.
+
+    - Fixed the ability to request an empty backup --suffix when sending
+      files to an rsync daemon.
+
+  INTERNAL:
+
+    - Most of the I/O is now buffered, which results in a pretty large
+      speedup when running under MS Windows.  (Craig Barratt)
+
+    - Optimizations to the name-handling/comparing code have made some
+      significant reductions in user-CPU time for large file sets.
+
+    - Some cleanup of the variable types make the code more consistent.
+
+    - Reduced memory requirements of hard link preservation.
+      (J.W. Schultz)
+
+    - Implemented a new algorithm for hard-link handling that speeds up
+      the code significantly.  (J.W. Schultz and Wayne Davison)
+
+    - The --hard-link option now uses the first existing file in the
+      group of linked files as the basis for the transfer.  This
+      prevents the sub-optimal transfer of a file's data when a new
+      hardlink is added on the sending side and it sorts alphabetically
+      earlier in the list than the files that are already present on the
+      receiving side.
+
+    - Dropped support for protocol versions less than 20 (2.3.0 released
+      15 Mar 1999) and activated warnings for protocols less than 25
+      (2.5.0 released 23 Aug 2001). (Wayne Davison and J.W. Schultz,
+      severally)
+
+    - More optimal data transmission for --hard-links (protocol 28).
+
+    - More optimal data transmission for --checksum (protocol 28).
+
+    - Less memory is used when --checksum is specified.
+
+    - Less memory is used in the file list (a per-file savings).
+
+    - The generator is now better about not modifying the file list
+      during the transfer in order to avoid a copy-on-write memory
+      bifurcation (on systems where fork() uses shared memory).
+      Previously, rsync's shared memory would slowly become unshared,
+      resulting in real memory usage nearly doubling on the receiving
+      side by the end of the transfer.  Now, as long as permissions
+      are being preserved, the shared memory should remain that way
+      for the entire transfer.
+
+    - Changed hardlink info and file_struct + strings to use allocation
+      pools.  This reduces memory use for large file-sets and permits
+      freeing memory to the OS.  (J.W. Schultz) 
+
+    - The 2 pipes used between the receiver and generator processes
+      (which are forked on the same machine) were reduced to 1 pipe and
+      the protocol improved so that (1) it is now impossible to have the
+      "redo" pipe fill up and hang rsync, and (2) trailing messages from
+      the receiver don't get lost on their way through the generator
+      over to the sender (which mainly affected hard-link messages and
+      verbose --stats output).
+
+    - Improved the internal uid/gid code to be more portable and a
+      little more optimized.
+
+    - The device numbers sent when using --devices are now sent as
+      separate major/minor values with 32-bit accuracy (protocol 28).
+      Previously, the copied devices were sent as a single 32-bit
+      number.  This will make inter-operation of 64-bit binaries more
+      compatible with their 32-bit brethren (with both ends of the
+      connection are using protocol 28).  Note that optimizations in the
+      binary protocol for sending the device numbers often results in
+      fewer bytes being used than before, even though more precision is
+      now available.
+
+    - Some cleanup of the exclude/include structures and its code made
+      things clearer (internally), simpler, and more efficient.
+
+    - The reading & writing of the file-list in batch-mode is now
+      handled by the same code that sends & receives the list over the
+      wire.  This makes it much easier to maintain.  (Note that the
+      batch code is still considered to be experimental.)
+
+  BUILD CHANGES:
+
+    - The configure script now accepts --with-rsyncd-conf=PATH to
+      override the default value of the /etc/rsyncd.conf file.
+
+    - Fixed configure bug when running "./configure --disable-ipv6".
+
+    - Fixed compilation problem on Tru64 Unix (having to do with
+      sockaddr.sa_len and sockaddr.sin_len).
+
+  DEVELOPER RELATED:
+
+    - Fixed "make test" bug when build dir is not the source dir.
+
+    - Added a couple extra diffs in the "patches" dir, removed the ones
+      that got applied, and rebuilt the rest.

+NEWS for rsync 2.6.0 (1 Jan 2004)
+Protocol: 27 (changed)
+Changes since 2.5.7:
+
+  ENHANCEMENTS:
+
+    * "ssh" is now the default remote shell for rsync.  If you want to
+      change this, configure like this:  "./configure --with-rsh=rsh".
+
+    * Added --files-from, --no-relative, --no-implied-dirs, and --from0.
+      Note that --from0 affects the line-ending character for all the
+      files read by the --*-from options. (Wayne Davison)
+
+    * Length of csum2 is now per-file starting with protocol version
+      27. (J.W. Schultz)
+
+    * Per-file dynamic block size is now sqrt(file length).  The
+      per-file checksum size is determined according to an algorithm
+      provided by Donovan Baarda which reduces the probability of rsync
+      algorithm corrupting data and falling back using the whole md4
+      checksums. (J.W. Schultz, Donovan Baarda)
+
+    * The --stats option no longer includes the (debug) malloc summary
+      unless the verbose option was specified at least twice.
+
+    * Added a new error/warning code for when files vanish from the
+      sending side.  Made vanished source files not interfere with the
+      file-deletion pass when --delete-after was specified.
+
+    * Various trailing-info sections are now preceded by a newline.
+
+  BUG FIXES:
+
+    * Fixed several exclude/include matching bugs when using wild-cards.
+      This has a several user-visible effects, all of which make the
+      matching more consistent and intuitive.  This should hopefully not
+      cause anyone problems since it makes the matching work more like
+      what people are expecting. (Wayne Davison)
+
+      - A pattern with a "**" no longer causes a "*" to match slashes.
+        For example, with "/*/foo/**", "foo" must be 2 levels deep.
+	[If your string has BOTH "*" and "**" wildcards, changing the
+	"*" wildcards to "**" will provide the old behavior in all
+	versions.]
+
+      - "**/foo" now matches at the base of the transfer (like /foo
+        does).  [Use "/**/foo" to get the old behavior in all versions.]
+
+      - A non-anchored wildcard term floats to match beyond the base of
+        the transfer.  E.g. "CVS/R*" matches at the end of the path,
+        just like the non-wildcard term "CVS/Root" does. [Use "/CVS/R*"
+        to get the old behavior in all versions.]
+
+      - Including a "**" in the match term causes it to be matched
+        against the entire path, not just the name portion, even if
+        there aren't any interior slashes in the term.  E.g. "foo**bar"
+        would exclude "/path/foo-bar" (just like before) as well as
+        "/foo-path/baz-bar" (unlike before).  [Use "foo*bar" to get the
+        old behavior in all versions.]
+
+    * The exclude list specified in the daemon's config file is now
+      properly applied to the pulled items no matter how deep the
+      user's file-args are in the source tree.  (Wayne Davison)
+
+    * For protocol version >= 27, mdfour_tail() is called when the
+      block size (including checksum_seed) is a multiple of 64.
+      Previously it was not called, giving the wrong MD4 checksum.
+      (Craig Barratt)
+
+    * For protocol version >= 27, a 64 bit bit counter is used in
+      mdfour.c as required by the RFC.  Previously only a 32 bit bit
+      counter was used, causing incorrect MD4 file checksums for
+      file sizes >= 512MB - 4.  (Craig Barratt)
+
+    * Fixed a crash bug when interacting with older rsync versions and
+      multiple files of the same name are destined for the same dir.
+      (Wayne Davison)
+
+    * Keep tmp names from overflowing MAXPATHLEN.
+
+    * Make --link-dest honor the absence of -p, -o, and -g.
+
+    * Made rsync treat a trailing slash in the destination in a more
+      consistent manner.
+
+    * Fixed file I/O error detection.  (John Van Essen)
+
+    * Fixed bogus "malformed address {hostname}" message in rsyncd log
+      when checking IP address against hostnames from "hosts allow"
+      and "hosts deny" parameters in config file.
+
+    * Print heap statistics when verbose >= 2 instead of when >= 1.
+
+    * Fixed a compression (-z) bug when syncing a mostly-matching file
+      that contains already-compressed data.  (Yasuoka Masahiko and
+      Wayne Davison)
+
+    * Fixed a bug in the --backup code that could cause deleted files
+      to not get backed up.
+
+    * When the backup code makes new directories, create them with mode
+      0700 instead of 0755 (since the directory permissions in the
+      backup tree are not yet copied from the main tree).
+
+    * Call setgroups() in a more portable manner.
+
+    * Improved file-related error messages to better indicate exactly
+      what pathname failed. (Wayne Davison)
+
+    * Fixed some bugs in the handling of --delete and --exclude when
+      using the --relative (-R) option. (Wayne Davison)
+
+    * Fixed bug that prevented regular files from replacing
+      special files and caused a directory in --link-dest or
+      --compare-dest to block the creation of a file with the
+      same path.  A directory still cannot be replaced by a
+      regular file unless --delete specified.  (J.W. Schultz)
+
+    * Detect and report when open or opendir succeed but read and
+      readdir fail caused by network filesystem issues and truncated
+      files.  (David Norwood, Michael Brown, J.W. Schultz)
+
+    * Added a fix that should give ssh time to restore the tty settings
+      if the user presses Ctrl-C at an ssh password prompt.
+
+  INTERNAL:
+
+    * Eliminated vestigial support for old versions that we stopped
+      supporting. (J.W. Schultz)
+
+    * Simplified some of the option-parsing code. (Wayne Davison)
+
+    * Some cleanup made to the exclude code, as well as some new
+      defines added to enhance readability. (Wayne Davison)
+
+    * Changed the protocol-version code so that it can interact at a
+      lower protocol level than the maximum supported by both sides.
+      Added an undocumented option, --protocol=N, to force the value
+      we advertise to the other side (primarily for testing purposes).

-Hard-link handling
-
-  At the moment hardlink handling is very expensive, so it's off by
-  default.  It does not need to be so.
-
-  Since most of the solutions are rather intertwined with the file
-  list it is probably better to fix that first, although fixing
-  hardlinks is possibly simpler.
-
-  We can rule out hardlinked directories since they will probably
-  screw us up in all kinds of ways.  They simply should not be used.
-
-  At the moment rsync only cares about hardlinks to regular files.  I
-  guess you could also use them for sockets, devices and other beasts,
-  but I have not seen them.
-
-  When trying to reproduce hard links, we only need to worry about
-  files that have more than one name (nlinks>1 && !S_ISDIR).
-
-  The basic point of this is to discover alternate names that refer to
-  the same file.  All operations, including creating the file and
-  writing modifications to it need only to be done for the first name.
-  For all later names, we just create the link and then leave it
-  alone.
-
-  If hard links are to be preserved:
-
-    Before the generator/receiver fork, the list of files is received
-    from the sender (recv_file_list), and a table for detecting hard
-    links is built.
-
-    The generator looks for hard links within the file list and does
-    not send checksums for them, though it does send other metadata.
-
-    The sender sends the device number and inode with file entries, so
-    that files are uniquely identified.
-
-    The receiver goes through and creates hard links (do_hard_links)
-    after all data has been written, but before directory permissions
-    are set.
-
-  At the moment device and inum are sent as 4-byte integers, which
-  will probably cause problems on large filesystems.  On Linux the
-  kernel uses 64-bit ino_t's internally, and people will soon have
-  filesystems big enough to use them.  We ought to follow NFS4 in
-  using 64-bit device and inode identification, perhaps with a
-  protocol version bump.
-
-  Once we've seen all the names for a particular file, we no longer
-  need to think about it and we can deallocate the memory.
-
-  We can also have the case where there are links to a file that are
-  not in the tree being transferred.  There's nothing we can do about
-  that.  Because we rename the destination into place after writing,
-  any hardlinks to the old file are always going to be orphaned.  In
-  fact that is almost necessary because otherwise we'd get really
-  confused if we were generating checksums for one name of a file and
-  modifying another.
-
-  At the moment the code seems to make a whole second copy of the file
-  list, which seems unnecessary.
-
-  We should have a test case that exercises hard links.  Since it
-  might be hard to compare ./tls output where the inodes change we
-  might need a little program to check whether several names refer to
-  the same file.

+.SH DESCRIPTION
+.P
+The pool allocation routines use
+.B malloc()
+for underlying memory management.
+What allocation pools do is cause
+memory within a given pool to be in large contigious blocks
+(called extents) that when freed will be reusable.  Unlike
+.B malloc()
+the allocations are not managed individually.
+Instead each extent tracks the total free memory within the
+extent.  Each extent can either be used to allocate memory
+or to manage the freeing of memory within that extent.
+When an extent has less free memory than a given
+allocation request or when the first request to free
+memory within that extent is received the extent ceases to
+be used for allocation.
+.P
+This form of memory management is suited to large numbers of small
+related allocations that are held for a while
+and then freed as a group.
+Because the
+underlying allocations are done in large contigious extents
+when an extent is freed it releases a large enough
+contigious block of memory to be useful to subsequent
+.B malloc()
+and
+.B pool_alloc()
+calls even if allocations from other pools or from
+.B malloc()
+are made between allocations from a given pool.
+.P
+.B pool_create()
+Creates an allocation pool for subsequent calls to the pool
+allocation functions.
+When an extent is created for allocations it will be
+.I size 
+bytes.
+Allocations from the pool have their sizes rounded up to a
+multiple of
+.I quantum
+bytes in length.
+Specifying
+.B 0
+for
+.I quantum
+Will produce a quantum that should meet maximal allignment
+on most platforms.
+If the
+.B POOL_QALIGN
+.I flag
+is set allocations will be aligned to addresses that are a
+multiple of
+.IR quantum .
+If the
+.B POOL_CLEAR
+.I flag
+is set all allocations from the pool will be zero filled.
+.P
+.B pool_destroy()
+destroys an allocation pool and frees all memory allocated
+in that pool.
+.P
+.B pool_alloc()
+allocates
+.I size
+bytes from the specified
+.IR pool .
+If
+.I size
+is
+.B 0
+.I quantum
+bytes will be freed.
+If the requested memory cannot be allocated
+.B pool_alloc()
+will call
+.I bomb()
+function, if defined, with
+.I msg
+as it's sole argument and
+.B NULL
+will be returned.
+.P
+.B pool_free()
+frees
+.I size
+bytes pointed to by
+.I addr
+previously allocated in the specified
+.IR pool .
+The memory freed within an extent will not be reusable until
+all of the memory in that extent has been freed but 
+depending on the order in which the
+allocations are freed some extents may be released for reuse
+while others are still in use.
+If
+.I size
+is
+.B 0
+.I quantum
+bytes will be freed.
+If
+.I addr
+is
+.B 0
+no memory will be freed but subsequent allocations will come
+from a new extent.
+.P
+.B pool_talloc()
+is a macro that take a
+.I type
+and
+.I count
+instead of
+.I size
+and will cast the return value to the correct type.
+.P
+.B pool_tfree
+is a macro to free memory previously allocated in the
+specified
+.IR pool .
+.SH RETURN VALUE
+.B pool_create()
+returns a pointer to
+.BR "struct alloc_pool" .
+.P
+.B pool_alloc()
+and
+.B pool_talloc()
+return pointers to the allocated memory,
+or NULL if the request fails.
+For each extent so long as no allocations are smaller than varaible
+allignment requirements this pointer will be suitably
+alligned for any kind of variable.
+The return type of
+.B pool_alloc()
+will normally require casting to the desired type but
+.B pool_talloc()
+will returns a pointer of the requested
+.IR type .
+.P
+.BR pool_free() ,
+.B pool_tfree()
+and
+.B pool_destroy()
+return no value.

-%description
-rsync is a replacement for rcp that has many more features.
-
-rsync uses the "rsync algorithm" which provides a very fast method for
-bringing remote files into sync. It does this by sending just the
-differences in the files across the link, without requiring that both
-sets of files are present at one of the ends of the link beforehand.
-
-A technical report describing the rsync algorithm is included with
-this package. 
-
-%changelog
-* Thu Jan 30 2003 Horst von Brand <vonbrand@inf.utfsm.cl>
-  Fixed "Sept" date in %changelog here
-  Use %{_mandir} to point to manpages
-  Support for compressed manpages (* at end catches them in %files)
-  Add doc/README-SGML and doc/rsync.sgml to %doc
-
-* Mon Sep 11 2000 John H Terpstra <jht@turbolinux.com>
-  Changed target paths to be Linux Standards Base compliant
-
-* Mon Jan 25 1999 Stefan Hornburg <racke@linuxia.de>
-  quoted RPM_OPT_FLAGS for the sake of robustness
-
-* Mon May 18 1998 Andrew Tridgell <tridge@samba.anu.edu.au>
-  reworked for auto-building when I release rsync (tridge@samba.anu.edu.au)
-
-* Sat May 16 1998 John H Terpstra <jht@aquasoft.com.au>
-  Upgraded to Rsync 2.0.6
-    -new feature anonymous rsync
-
-* Mon Apr  6 1998 Douglas N. Arnold <dna@math.psu.edu>
-
-Upgrade to rsync version 1.7.2.
-
-* Sun Mar  1 1998 Douglas N. Arnold <dna@math.psu.edu>
-
-Built 1.6.9-1 based on the 1.6.3-2 spec file of John A. Martin.
-Changes from 1.6.3-2 packaging: added latex and dvips commands
-to create tech_report.ps.
-
-* Mon Aug 25 1997 John A. Martin <jam@jamux.com>
-
-Built 1.6.3-2 after finding no rsync-1.6.3-1.src.rpm although there
-was an ftp://ftp.redhat.com/pub/contrib/alpha/rsync-1.6.3-1.alpha.rpm
-showing no packager nor signature but giving 
-"Source RPM: rsync-1.6.3-1.src.rpm".
-
-Changes from 1.6.2-1 packaging: added '$RPM_OPT_FLAGS' to make, strip
-to '%build', removed '%prefix'.
-
-* Thu Apr 10 1997 Michael De La Rue <miked@ed.ac.uk>

+In order to preserve usernames and groupnames, rsync needs to be able to
+use the standard library functions for looking up names and IDs (i.e.
+getpwuid(), getgrgid(), getpwname(), and getgrnam()).  This means a
