  mention what kind of a message it was trying to write, but the
  'phase "unknown"' output was ubiquitous and confusing.

-NEWS for rsync 2.6.3 (30 Sep 2004)
-Protocol: 28 (unchanged)
-Changes since 2.6.2:
-
-  SECURITY FIXES:
-
-    - 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".
-
-  OUTPUT CHANGES (ATTN: those using a script to parse the verbose output):
-
-    - 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".
-
-    - 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 "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.
+NEWS for rsync 2.6.8 (22 Apr 2006)
+Protocol: 29 (unchanged)
+Changes since 2.6.7:
 
   BUG FIXES:
 
-    - Fixed a crash bug that might appear when --delete was used and
-      multiple source directories were specified.
+    - Fixed a bug in the exclude code where an anchored exclude without any
+      wildcards fails to match an absolute source arg, but only when --relative
+      is in effect.
 
-    - Fixed a 32-bit truncation of the file length when generating the
-      checksums.
+    - Improved the I/O code for the generator to fix a potential hang when the
+      receiver gets an EOF on the socket but the generator's select() call
+      never indicates that the socket is writable for it to be notified about
+      the EOF.  (This can happen when using stunnel).
 
-    - The --backup code no longer attempts to create some directories
-      over and over again (generating warnings along the way).
+    - Fixed a problem with the file-reading code where a failed read (such as
+      that caused by a bad sector) would not advance the file's read-position
+      beyond the failed read's data.
 
-    - 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.
+    - Fixed a logging bug where the "log file" directive was not being honored
+      in a single-use daemon (one spawned by a remote-shell connection or by
+      init).
 
-    - 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.)
+    - If rsync cannot honor the --delete option, we output an error and exit
+      instead of silently ignoring the option.
 
-    - 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).
+    - Fixed a bug in the --link-dest code that prevented special files (such as
+      fifos) from being linked.
 
-    - 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.
-
-    - Got rid of a potential hang in the receiver when near the end of a
-      phase.
-
-    - When using --backup without a --backup-dir, rsync no longer preserves
-      the modify time on directories.  This avoids confusing NFS.
-
-    - 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".
-
-    - 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.
-
-    - 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).
-
-    - 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 daemon authentication code when using one of the
-      batch-processing options.
-
-    - 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).
-
-    - 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).
-
-    - 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).
-
-    - 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.
-
-    - 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.
-
-    - Fixed an age-old crash problem with --read-batch on a local copy
-      (rsync was improperly assuming --whole-file for the local copy).
-
-    - 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.
-
-    - 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.
-
-    - 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").
+    - The ability to hard-link symlinks and special files is now determined at
+      configure time instead of at runtime.  This fixes a bug with --link-dest
+      creating a hard-link to a symlink's referent on a BSD system.
 
   ENHANCEMENTS:
 
-    - 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.
+    - In daemon mode, if rsync fails to bind to the requested port, the
+      error(s) returned by socket() and/or bind() are now logged.
 
-    - 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.
+    - When we output a fatal error, we now output the version of rsync in the
+      message.
 
-    - 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).
+    - Improved the documentation for the --owner and --group options.
 
-    - Added the "write only" option for the daemon's config file.
+    - The rsyncstats script in "support" has an improved line-parsing regex
+      that is easier to read and also makes it to parse syslog-generated lines.
 
-    - Added long-option names for -4 and -6 (namely --ipv4 and --ipv6)
-      and documented all these options in the man page.
-
-    - Improved the handling of the --bwlimit option so that it's less
-      bursty, more accurate, and works properly over a larger range of
-      values.
-
-    - 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 the --checksum-seed=N option for advanced users.
-
-    - 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.
-
-    - 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.
-
-    - The daemon's "refuse options" config item now allows you to match
-      option names using wildcards and/or the single-letter option names.
-
-    - 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.
-
-    - Added the ability to parse a literal IPv6 address in an "rsync:" URL
-      (e.g. rsync://[2001:638:500:101::21]:873/module/dir).
-
-    - 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:
-
-    - Some cleanup in the exclude code has saved some per-exclude memory
-      and made the code easier to maintain.
-
-    - Improved the argv-overflow checking for a remote command that has a
-      lot of args.
-
-    - Use rsyserr() in the various places that were still calling rprintf()
-      with strerror() as an arg.
-
-    - 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).
-
-    - 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).
+    - A new script in "support": file-attr-restore, can be used to restore the
+      attributes of a file-set (the permissions, ownership, and group info)
+      taken from the cached output of a "find ARG... -ls" command.
 
   DEVELOPER RELATED:
 
-    - The scripts in the testsuite dir were cleaned up a bit and a few
-      new tests added.
+    - Removed the unused function write_int_named(), the unused variable
+      io_read_phase, and the rarely used variable io_write_phase.  This also
+      elides the confusing 'phase "unknown"' part of one error message.
 
-    - Some new diffs were added to the patches dir, and some accepted
-      ones were removed.
+    - Removed two unused configure checks and two related (also unused)
+      compatibility functions.
 
+    - The xattrs.diff patch received a security fix that prevents a potential
+      buffer overflow in the receive_xattr() code.
+
+    - The acls.diff patch has been improved quite a bit, with more to come.
+
+    - A new patch was added: log-file.diff.  This contains an early version of
+      a future option, --log-file=FILE, that will allow any rsync to log its
+      actions to a file (something that only a daemon supports at present).

 Handling duplicate names
 
-  We need to be careful of duplicate names getting into the file list.
-  See clean_flist().  This could happen if multiple arguments include
-  the same file.  Bad.
-
-  I think duplicates are only a problem if they're both flowing
-  through the pipeline at the same time.  For example we might have
-  updated the first occurrence after reading the checksums for the
-  second.  So possibly we just need to make sure that we don't have
-  both in the pipeline at the same time.
-
-  Possibly if we did one directory at a time that would be sufficient.
-
-  Alternatively we could pre-process the arguments to make sure no
-  duplicates will ever be inserted.  There could be some bad cases
-  when we're collapsing symlinks.
-
-  We could have a hash table.
-
-  The root of the problem is that we do not want more than one file
-  list entry referring to the same file.  At first glance there are
-  several ways this could happen: symlinks, hardlinks, and repeated
-  names on the command line.
-
-  If names are repeated on the command line, they may be present in
-  different forms, perhaps by traversing directory paths in different
-  ways, traversing paths including symlinks.  Also we need to allow
-  for expansion of globs by rsync.
-
-  At the moment, clean_flist() requires having the entire file list in
-  memory.  Duplicate names are detected just by a string comparison.
-
-  We don't need to worry about hard links causing duplicates because
-  files are never updated in place.  Similarly for symlinks.
-
-  I think even if we're using a different symlink mode we don't need
-  to worry.
-
-  Unless we're really clever this will introduce a protocol
-  incompatibility, so we need to be able to accept the old format as
-  well.
+  Some folks would like rsync to be deterministic in how it handles
+  duplicate names that come from mering multiple source directories
+  into a single destination directory; e.g. the last name wins.  We
+  could do this by switching our sort algorithm to one that will
+  guarantee that the names won't be reordered.  Alternately, we could
+  assign an ever-increasing number to each item as we insert it into
+  the list and then make sure that we leave the largest number when
+  cleaning the file list (see clean_flist()).  Another solution would
+  be to add a hash table, and thus never put any duplicate names into
+  the file list (and bump the protocol to handle this).

 %description
-rsync is a replacement for rcp that has many more features.
+Rsync uses a reliable algorithm to bring remote and host files into
+sync very quickly. Rsync is fast because it just sends the differences
+in the files over the network instead of sending the complete
+files. Rsync is often used as a very powerful mirroring process or
+just as a more capable replacement for the rcp command. A technical
+report which describes the rsync algorithm is included in this
+package.
 
-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.

-manpagesection(RUNNING AN RSYNC SERVER OVER A REMOTE SHELL PROGRAM)
-
-If rsync is run with both the --daemon and --rsh (-e) options, it will
-spawn an rsync daemon using a remote shell connection.  Several
-configuration options will not be available unless the remote user is
-root (e.g. chroot, setuid/setgid, etc.).  There is no need to configure
-inetd or the services map to include the rsync server port if you run an
-rsync server only via a remote shell program.
-
-ADVANCED: To run an rsync server out of a single-use ssh key, use the
-"command=em(COMMAND)" syntax in the remote user's authorized_keys entry,
-where command would be
-
-quote(rsync --server --daemon .)
-
-NOTE: rsync's argument parsing expects the trailing ".", so make sure
-that it's there.  If you want to use an rsyncd.conf(5)-style
-configuration file other than the default, you can added a
---config option to the em(command):
-
-quote(rsync --server --daemon --config=em(file) .)
-
-Note that the "--server" here is the internal option that rsync uses to
-run the remote version of rsync that it communicates with, and thus you
-should not be using the --server option under normal circumstances.

+
+This script lets you update a hierarchy of files in an atomic way by first
+creating a new hierarchy (using hard-links to leverage the existing files),
+and then swapping the new hierarchy into place.  You must be pulling files
+to a local directory, and that directory must already exist.  For example:
+
+    atomic-rsync -av host:/remote/files/ /local/files/
+
+This would make the transfer to the directory /local/files~new~ and then
+swap out /local/files at the end of the transfer by renaming it to
+/local/files~old~ and putting the new directory into its place.  The
+/local/files~old~ directory will be preserved until the next update, at
+which point it will be deleted.
+
+Do NOT specify this command:
+
+    atomic-rsync -av host:/remote/files /local/
+
+... UNLESS you want the entire /local dir to be swapped out!
+
+See the "rsync" command for its list of options.  You may not use the
+--link-dest or --compare-dest options (since this script uses --link-dest
+to make the transfer efficient).  Also, the destination directory cannot
+be "/".

+ * Note that this program aborts after 30 seconds of inactivity, so you'll need
+ * to change it if that is not enough dead time for your transfer.  Also, some
+ * of the above commands will not notice that the transfer is done (if we're
