Preparing for release of 3.0.7

This will give 3.0.7 the standard timeout handling with just a few
improvements: a fix for the detection of recent sender I/O, the use
of MSG_DATA for really old rsync versions, and better setting of
select_timeout for shorter timeout settings.

-NEWS for rsync 3.0.0 (UNRELEASED)
-Protocol: 30 (changed)
-Changes since 2.6.9:
-
-  NOTABLE CHANGES IN BEHAVIOR:
-
-    - The handling of implied directories when using --relative has changed to
-      send them as directories (e.g. no implied dir is ever sent as a symlink).
-      This avoids unexpected behavior and should not adversely affect most
-      people.  If you're one of those rare individuals who relied upon having
-      an implied dir be duplicated as a symlink, you should specify the
-      transfer of the symlink and the transfer of the referent directory as
-      separate args.  (See also --keep-dirlinks and --no-implied-dirs.)
-
-    - Requesting a remote file list without specifying -r (--recursive) now
-      sends the -d (--dirs) option to the remote rsync rather than sending -r
-      along with an extra exclude of /*/*.  If the remote rsync does not
-      understand the -d option (i.e. it is 2.6.3 or older), you will need to
-      either turn off -d (--no-d), or specify  -r --exclude='/*/*'  manually.
+NEWS for rsync 3.0.7 (31 Dec 2009)
+Protocol: 30 (unchanged)
+Changes since 3.0.6:
 
   BUG FIXES:
 
-    - Fixed the output of -ii when combined with one of the --*-dest options:
-      it now itemizes all the items, not just the changed ones.
+    - Fixed a bogus free when using --xattrs with --backup.
 
-    - Made the output of all file types consistent when using a --*-dest
-      option.  Prior versions would output too many creation events for
-      matching items.
+    - Avoid an error when --dry-run  was trying to stat a prior hard-link file
+      that hasn't really been created.
 
-    - The code that waits for a child pid now handles being interrupted by a
-      signal.  This fixes a problem with the pre-xfer exec function not being
-      able to get the exit status from the script.
+    - Fixed a problem with --compress (-z) where the receiving side could
+      return the error "inflate (token) returned -5".
 
-    - A negated filter rule (i.e. with a '!' modifier) no longer loses the
-      negation when sending the filter rules to the remote rsync.
+    - Fixed a bug where --delete-during could delete in a directory before it
+      noticed that the sending side sent an I/O error for that directory (both
+      sides of the transfer must be at least 3.0.7).
 
-    - Fixed a problem with the --out-format (aka --log-format) option %f:  it
-      no longer outputs superfluous directory info for a non-daemon rsync.
+    - Improved --skip-compress's error handling of bad character-sets and got
+      rid of a lingering debug fprintf().
 
-    - Fixed a problem with -vv (double --verbose) and --stats when "pushing"
-      files (which includes local copies).  Version 2.6.9 would complete the
-      copy, but exit with an error when the receiver output its memory stats.
+    - Fixed the daemon's conveyance of io_error value from the sender.
 
-    - If --password-file is used on a non-daemon transfer, rsync now complains
-      and exits.  This should help users figure out that they can't use this
-      option to control a remote shell's password prompt.
+    - An rsync daemon use seteuid() (when available) if it used setuid().
 
-    - Make sure that directory permissions of a newly-created destination
-      directory are handled right when --perms is left off.
+    - Get the permissions right on a --fake-super transferred directory that
+      needs more owner permissions to emulate root behavior.
 
-    - The itemized output of a newly-created destination directory is now
-      output as a creation event, not a change event.
+    - An absolute-path filter rule (i.e. with a '/' modifier) no longer loses
+      its modifier when sending the filter rules to the remote rsync.
 
-    - Improved --hard-link so that more corner cases are handled correctly
-      when combined with options such as --link-dest and/or --ignore-existing.
+    - Improved the "--delete does not work without -r or -d" message.
 
-    - The --append option no longer updates a file that has the same size.
+    - Improved rsync's handling of --timeout to avoid a weird timeout case
+      where the sender could timeout even though it has recently written data
+      to the socket (but hasn't read data recently, due to the writing).
 
-    - Fixed a bug when combining --backup and --backup-dir with --inplace:
-      any missing backup directories are now created.
+    - Some misc manpage improvements.
 
-    - Fixed a bug when using --backup and --inplace with --whole-file or
-      --read-batch: backup files are actually created now.
+    - Fixed the chmod-temp-dir testsuite on a system without /var/tmp.
 
-    - Starting up an extra copy of an rsync daemon will not clobber the pidfile
-      for the running daemon -- if the pidfile exists, the new daemon will exit
-      with an error.
+    - Make sure that a timeout specified in the daemon's config is used as a
+      maximum timeout value when the user also specifies a timeout.
 
-    - The daemon pidfile is checked and created sooner in the startup sequence.
+    - Improved the error-exit reporting when rsync gets an error trying to
+      cleanup after an error:  the initial error is reported.
 
-    - If a daemon module's "path" value is not an absolute pathname, the code
-      now makes it absolute internally (making it work properly).
+    - Improved configure's detection of IPv6 for solaris and cygwin.
 
-  ENHANCEMENTS:
+    - The AIX sysacls routines will now return ENOSYS if ENOTSUP is missing.
 
-    - A new incremental-recursion algorithm is now used when rsync is talking
-      to another 3.x version.  This starts the transfer going more quickly
-      (before all the files have been found), and requires much less memory.
-      See the --recursive option in the manpage for some restrictions.
+    - Made our (only used if missing) getaddrinfo() routine use inet_pton()
+      (which we also provide) instead of inet_aton().
 
-    - Lowered memory use in the non-incremental-recursion algorithm for typical
-      option values (usually saving from 21-29 bytes per file).
-
-    - The default --delete algorithm is now --delete-during when talking to a
-      3.x rsync.  This is a faster scan than using --delete-before (which is
-      the default when talking to older rsync versions), and is compatible with
-      the new incremental recursion mode.
-
-    - Rsync now allows multiple remote-source args to be specified rather than
-      having to rely on a special space-splitting side-effect of the remote-
-      shell.  Additional remote args must specify the same host or an empty one
-      (e.g. empty:  :file1  or  ::module/file2).  This means that local use of
-      brace expansion now works:  rsync -av host:dir/{f1,f2} .
-
-    - Added the --protect-args (-s) option, that tells rsync to send most of
-      the command-line args at the start of the transfer rather than as args
-      to the remote-shell command.  This protects them from space-splitting,
-      and only interprets basic wildcard special shell characters (*?[).
-
-    - Added the --delete-delay option, which is a more efficient way to delete
-      files at the end of the transfer without needing a separate delete pass.
-
-    - Added the --acls (-A) option to preserve Access Control Lists.  This is
-      an improved version of the prior patch that was available, and it even
-      supports OS X ACLs.  If you need to have backward compatibility with old,
-      acl-patched versions of rsync, apply the acls.diff file from the patches
-      dir.
-
-    - Added the --xattrs (-X) option to preserver extended attributes.  This is
-      an improved version of the prior patch that was available, and it even
-      supports OS X xattrs (which includes their resource fork data).  If you
-      need to have backward compatibility with old, xattr-patched versions of
-      rsync, apply the xattrs.diff file from the patches dir.
-
-    - Added the --fake-super option that allows a non-super user to preserve
-      all attributes of a file by using a special extended-attribute idiom.
-      It even supports the storing of foreign ACL data on your backup server.
-      There is also an analogous "fake super" option for an rsync daemon.
-
-    - Added the --iconv option, which allows rsync to convert filenames from
-      one character-set to another during the transfer.  The default is to make
-      this feature available as long as your system has iconv_open().  If
-      compilation fails, specify --disable-iconv to configure, and then
-      rebuild.  If you want rsync to perform character-set conversions by
-      default, you can specify --enable-iconv=CONVERT_STRING with the default
-      value for the --iconv option that you wish to use.  For example,
-      "--enable-iconv=." is a good choice.  See the rsync manpage for an
-      explanation of the --iconv option's settings.
-
-    - Added the --skip-compress=LIST option to override the default list of
-      file suffixes that will not be compressed when using --compress.
-      
-    - The daemon's default for "dont compress" was extended to include:
-	  *.7z *.mp[34] *.mov *.avi *.ogg *.jpg *.jpeg
-      The matching routine was also optimized to run more quickly.
-
-    - The --max-delete option now outputs a warning if it skipped any file
-      deletions, including a count of how many deletions were skipped.  (Older
-      versions just silently stopped deleting things.)
-
-    - You may specify --max-delete=0 to a 3.0.0 client to request that it warn
-      about extraneous files without deleting anything.  If you're not sure
-      what version the client is, you can use the less-obvious --max-delete=-1,
-      as both old and new versions will treat that as the same request (though
-      older versions don't warn).
-
-    - The --hard-link option now uses less memory on both the sending and
-      receiving side for all protocol versions.  For protocol 30, the use of a
-      hashtable on the sending side allows us to more efficiently convey to the
-      receiver what files are linked together.  This reduces the amount of data
-      sent over the socket by a considerable margin (rather than adding more
-      data), and limits the in-memory storage of the device+inode information
-      to just the sending side for the new protocol 30, or to the receiving
-      side when speaking an older protocol (note that older rsync versions kept
-      the device+inode information on both sides).
-
-    - The filter rules now support a perishable ("p") modifier that marks rules
-      that should not have an effect in a directory that is being deleted.  e.g.
-      -f '-p .svn/' would only affect "live" .svn directories.
-
-    - If we get an error setting the time on a symlink, we don't complain about
-      it anymore (since some operating systems don't support that, and it's not
-      that important).
-
-    - Protocol 30 now uses MD5 checksums instead of MD4.
-
-    - Changed the --append option to not checksum the existing data in the
-      destination file, which speeds up file appending.
-
-    - Added the --append-verify option, which works like the older --append
-      option (verifying the existing data in the destination file).  For
-      compatibility with older rsync versions, any use of --append that is
-      talking protocol 29 or older will revert to the --append-verify method.
-
-    - Documented and extended the support for the RSYNC_CONNECT_PROG variable
-      that can be used to enhance the client side of a daemon connection.
-
-    - Improved the dashes and double-quotes in the nroff manpage output.
-
-    - We now support a lot more --no-OPTION override options.
-
-  INTERNAL:
-
-    - The file-list sorting algorithm now uses a sort that keeps any same-
-      named items in the same order as they were specified.  This allows
-      rsync to always ensure that the first of the duplicates is the one
-      that will be included in the copy.  The new sort was also faster
-      than the glibc version of qsort() and mergesort() in my testing.
-
-    - Rsync now supports the transfer of 64-bit timestamps (time_t values).
-
-    - Fixed a build problem with older (2.x) versions of gcc.
-
-    - Added some isType() functions that make dealing with signed characters
-      easier without forcing variables via casts.
-
-    - Changed strcat/strcpy/sprintf function calls to use safer versions.
-
-    - Upgraded the included popt version to 1.10.2 and improved its use of
-      string-handling functions.
-
-    - Added missing prototypes for compatibility functions from the lib dir.
-
-    - Configure determines if iconv() has a const arg, allowing us to avoid a
-      compiler warning.
-
-    - Made the sending of some numbers more efficient for protocol 30.
-
-    - Make sure that a daemon process doesn't mind if the client was weird and
-      omitted the --server option.
-
-    - Improved the use of "const" on pointers.
-
-    - Improved J.W.'s pool_alloc routines to add a way of freeing older
-      sections of a pool's memory.
+    - The exit-related debug messages now mention the program's role so it is
+      clear who output what message.
 
   DEVELOPER RELATED:
 
-    - Rsync is now licensed under the GPLv3 or later.
+    - Got rid of type-punned compiler warnings output by newer gcc versions.
 
-    - When running the tests, we now put our per-test temp dirs into a sub-
-      directory named testtmp (which is created, if missing).  This allows
-      someone to symlink the testtmp directory to another filesystem (which is
-      useful if the build dir's filesystem does not support ACLs and xattrs,
-      but another file system does).
+    - The Makefile now ensures that proto.h will be rebuilt if config.h changes.
 
-    - Rsync now has a way of handling protocol-version changes during the
-      development of a new protocol version.  This causes any out-of-sync
-      versions to speak an older protocol rather than fail in a cryptic manner.
-      This addition makes it safe to deploy a pre-release version that may
-      interact with the public.  This new exchange of sub-version info does not
-      interfere with the {MIN,MAX}_PROTOCOL_VERSION checking algorithm (which
-      does not have enough range to allow the main protocol number to be
-      incremented for every minor tweak in that happens during development).
+    - The testsuite no longer uses "id -u", so it works better on solaris.

+NEWS for rsync 3.0.6 (8 May 2009)
+Protocol: 30 (unchanged)
+Changes since 3.0.5:
+
+  BUG FIXES:
+
+    - Fixed a --read-batch hang when rsync is reading a batch file that was
+      created from an incremental-recursion transfer.
+
+    - Fixed the daemon's socket code to handle the simultaneous arrival of
+      multiple connections.
+
+    - Fix --safe-links/--copy-unsafe-links to properly handle symlinks that
+      have consecutive slashes in the value.
+
+    - Fixed the parsing of an [IPv6_LITERAL_ADDR] when a USER@ is prefixed.
+
+    - The sender now skips a (bogus) symlink that has a 0-length value, which
+      avoids a transfer error in the receiver.
+
+    - Fixed a case where the sender could die with a tag-0 error if there was
+      an I/O during the sending of the file list.
+
+    - Fixed the rrsync script to avoid a server-side problem when -e is at the
+      start of the short options.
+
+    - Fixed a problem where a vanished directory could turn into an exit code
+      23 instead of the proper exit code 24.
+
+    - Fixed the --iconv conversion of symlinks when doing a local copy.
+
+    - Fixed a problem where --one-file-system was not stopping deletions on the
+      receiving side when a mount-point directory did not match a directory in
+      the transfer.
+
+    - Fixed the dropping of an ACL mask when no named ACL values were present.
+
+    - Fixed an ACL/xattr corruption issue where the --backup option could cause
+      rsync to associate the wrong ACL/xattr information with received files.
+
+    - Fixed the use of --xattrs with --only-write-batch.
+
+    - Fixed the use of --dry-run with --read-batch.
+
+    - Fixed configure's erroneous use of target.
+
+    - Fixed configure's --disable-debug option.
+
+    - Fixed a run-time issue for systems that can't find iconv_open() by adding
+      the --disable-iconv-open configure option.
+
+    - Complain and die if the user tries to combine --remove-source-files (or
+      the deprecated --remove-sent-files) with --read-batch.
+
+    - Fixed an failure transferring special files from Solaris to Linux.
+
+
+NEWS for rsync 3.0.5 (28 Dec 2008)
+Protocol: 30 (unchanged)
+Changes since 3.0.4:
+
+  BUG FIXES:
+
+    - Initialize xattr data in a couple spots in the hlink code, which avoids a
+      crash when the xattr pointer's memory happens to start out non-zero.
+      Also fixed the itemizing of an alt-dest file's xattrs when hard-linking.
+
+    - Don't send a bogus "-" option to an older server if there were no short
+      options specified.
+
+    - Fixed skipping of unneeded updates in a batch file when incremental
+      recursion is active.  Added a test for this.  Made batch-mode handle
+      "redo" files properly (and without hanging).
+
+    - Fix the %P logfile escape when the daemon logs from inside a chroot.
+
+    - Fixed the use of -s (--protect-args) when used with a remote source or
+      destination that had an empty path (e.g. "host:").  Also fixed a problem
+      when -s was used when accessing a daemon via a remote-shell.
+
+    - Fixed the use of a dot-dir path (e.g. foo/./bar) inside a --files-from
+      file when the root of the transfer isn't the current directory.
+
+    - Fixed a bug with "-K --delete" removing symlinks to directories when
+      incremental recursion is active.
+
+    - Fixed a hard to trigger hang when using --remove-source-files.
+
+    - Got rid of an annoying delay when accessing a daemon via a remote-shell.
+
+    - Properly ignore (superfluous) source args on a --read-batch command.
+
+    - Improved the manpage's description of the '*' wildcard to remove the
+      confusing "non-empty" qualifier.
+
+    - Fixed reverse lookups in the compatibility-library version of
+      getnameinfo().
+
+    - Fixed a bug when using --sparse on a sparse file that has over 2GB of
+      consecutive sparse data.
+
+    - Avoid a hang when using at least 3 --verbose options on a transfer with a
+      client sender (which includes local copying).
+
+    - Fixed a problem with --delete-delay reporting an error when it was ready
+      to remove a directory that was now gone.
+
+    - Got rid of a bunch of "warn_unused_result" compiler warnings.
+
+    - If an ftruncate() on a received file fails, it now causes a partial-
+      transfer warning.
+
+    - Allow a path with a leading "//" to be preserved (CYGWIN only).
+
+  ENHANCEMENTS:
+
+    - Made the support/atomic-rsync script able to perform a fully atomic
+      update of the copied hierarchy when the destination is setup using a
+      particular symlink idiom.
+
+
+NEWS for rsync 3.0.4 (6 Sep 2008)
+Protocol: 30 (unchanged)
+Changes since 3.0.3:
+
+  BUG FIXES:
+
+    - Fixed a bug in the hard-linking code where it would sometimes try to
+      allocate 0 bytes of memory (which fails on some OSes, such as AIX).
+
+    - Fixed the hard-linking of files from a device that has a device number
+      of 0 (which seems to be a common device number on NetBSD).
+
+    - Fixed the handling of a --partial-dir that cannot be created.  This
+      particularly impacts the --delay-updates option (since the files cannot
+      be delayed without a partial-dir), and was potentially destructive if
+      the --remove-source-files was also specified.
+
+    - Fixed a couple issues in the --fake-super handling of xattrs when the
+      destination files have root-level attributes (e.g. selinux values) that
+      a non-root copy can't affect.
+
+    - Improved the keep-alive check in the generator to fire consistently in
+      incremental-recursion mode when --timeout is enabled.
+
+    - The --iconv option now converts the content of a symlink too, instead
+      of leaving it in the wrong character-set (requires 3.0.4 on both sides
+      of the transfer).
+
+    - When using --iconv, if a filename fails to convert on the receiving side,
+      this no longer makes deletions in the root-dir of the transfer fail
+      silently (the user now gets a warning about deletions being disabled
+      due to IO error as long as --ignore-errors was not specified).
+
+    - When using --iconv, if a server-side receiver can't convert a filename,
+      the error message sent back to the client no longer mangles the name
+      with the wrong charset conversion.
+
+    - Fixed a potential alignment issue in the IRIX ACL code when allocating
+      the initial "struct acl" object.  Also, cast mallocs to avoid warnings.
+
+    - Changed some errors that were going to stdout to go to stderr.
+
+    - Made human_num() and human_dnum() able to output a negative number
+      (rather than outputting a cryptic string of punctuation).
+
+  ENHANCEMENTS:
+
+    - Rsync will avoid sending an -e option to the server if an older protocol
+      is requested (and thus the option would not be useful).  This lets the
+      user specify the --protocol=29 option to access an overly-restrictive
+      server that is rejecting the protocol-30 use of -e to the server.
+
+    - Improved the message output for an RERR_PARTIAL exit.
+
+  DEVELOPER RELATED:
+
+    - The Makefile will not halt for just a timestamp change on the Makefile
+      or the configure files, only for actual changes in content.
+
+    - Changed some commands in the testsuite's xattrs.test that called "rsync"
+      instead of "$RSYNC".
+
+    - Enhanced the release scripts to be able to handle a branch release and
+      to do even more consistency checks on the files.

+NEWS for rsync 3.0.3 (29 Jun 2008)
+Protocol: 30 (unchanged)
+Changes since 3.0.2:
+
+  BUG FIXES:
+
+    - Fixed a wildcard matching problem in the daemon when a module has
+      "use chroot" enabled.
+
+    - Fixed a crash bug in the hard-link code.
+
+    - Fixed the sending of xattr directory information when the code finds a
+      --link-dest or --copy-dest directory with unchanged xattrs -- the
+      destination directory now gets these unchanged xattrs properly applied.
+
+    - Fixed an xattr-sending glitch that could cause an "Internal abbrev"
+      error.
+
+    - Fixed the combination of --xattrs and --backup.
+
+    - The generator no longer allows a '.' dir to be excluded by a daemon-
+      exclude rule.
+
+    - Fixed deletion handling when copying a single, empty directory (with no
+      files) to a differently named, non-existent directory.
+
+    - Fixed the conversion of spaces into dashes in the %M log escape.
+
+    - Fixed several places in the code that were not returning the right
+      errno when a function failed.
+
+    - Fixed the backing up of a device or special file into a backup dir.
+
+    - Moved the setting of the socket options prior to the connect().
+
+    - If rsync exits in the middle of a --progress output, it now outputs a
+      newline to help prevent the progress line from being overwritten.
+
+    - Fixed a problem with how a destination path with a trailing slash or
+      a trailing dot-dir was compared against the daemon excludes.
+
+    - Fixed the sending of large (size > 16GB) files when talking to an older
+      rsync (protocols < 30):  we now use a compatible block size limit.
+
+    - If a file's length is so huge that we overflow a checksum buffer count
+      (i.e. several hundred TB), warn the user and avoid sending an invalid
+      checksum struct over the wire.
+
+    - If a source arg is excluded, --relative no longer adds the excluded
+      arg's implied dirs to the transfer.  This fix also made the exclude
+      check happen in the better place in the sending code.
+
+    - Use the overflow_exit() function for overflows, not out_of_memory().
+
+    - Improved the code to better handle a system that has only 32-bit file
+      offsets.
+
+  ENHANCEMENTS:
+
+    - The rsyncd.conf manpage now consistently refers to the parameters in
+      the daemon config file as "parameters".
+
+    - The description of the --inplace option was improved.
+
+  EXTRAS:
+
+    - Added a new script in the support directory, deny-rsync, which allows
+      an admin to (temporarily) replace the rsync command with a script that
+      sends an error message to the remote client via the rsync protocol.
+
+  DEVELOPER RELATED:
+
+    - Fixed a testcase failure if the tests are run as root and made some
+      compatibility improvements.
+
+    - Improved the daemon tests, including checking module comments, the
+      listing of files, and the ensuring that daemon excludes can't affect
+      a dot-dir arg.
+
+    - Improved some build rules for those that build in a separate directory
+      from the source, including better install rules for the man pages, and
+      the fixing of a proto.h-tstamp rule that could make the binaries get
+      rebuild without cause.
+
+    - Improved the testsuite to work around a problem with some utilities
+      (e.g. cp -p & touch -r) rounding sub-second timestamps.
+
+    - Ensure that the early patches don't cause any generated-file hunks to
+      bleed-over into patches that follow.

+
+  ENHANCEMENTS:
+
+    - None.
+
+  DEVELOPER RELATED:

+
+NEWS for rsync 3.0.1 (3 Apr 2008)
+Protocol: 30 (unchanged)
+Changes since 3.0.0:
+
+  NOTABLE CHANGES IN BEHAVIOR:
+
+    - Added the 'c'-flag to the itemizing of non-regular files so that the
+      itemized output doesn't get hidden if there were no attribute changes,
+      and also so that the itemizing of a --copy-links run will distinguish
+      between copying an identical non-regular file and the creation of a
+      revised version with a new value (e.g. a changed symlink referent, a
+      new device number, etc.).
+
+  BUG FIXES:
+
+    - Fixed a crash bug when a single-use rsync daemon (via remote shell) was
+      run without specifying a --config=FILE option.
+
+    - Fixed a crash when backing up a directory that has a default ACL.
+
+    - Fixed a bug in the handling of xattr values that could cause rsync to
+      not think that a file's extended attributes are up-to-date.
+
+    - Fixed the working of --fake-super with --link-dest and --xattrs.
+
+    - Fixed a hang when combining --dry-run with --remove-source-files.
+
+    - Fixed a bug with --iconv's handling of files that cannot be converted:
+      a failed name can no longer cause a transfer failure.
+
+    - Fixed the building of the rounding.h file on systems that need custom
+      CPPFLAGS to be used.  Also improved the error reporting if the building
+      of rounding.h fails.
+
+    - Fixed the use of the --protect-args (-s) option when talking to a daemon.
+
+    - Fixed the --ignore-existing option's protection of files on the receiver
+      that are non-regular files on the sender (e.g. if a symlink or a dir on
+      the sender is trying to replace a file on the receiver).  The reverse
+      protection (protecting a dir/symlink/device from being replaced by a
+      file) was already working.
+
+    - Fixed an assert failure if --hard-links is combined with an option that
+      can skip a file in a set of hard-linked files (i.e. --ignore-existing,
+      --append, etc.), without skipping all the files in the set.
+
+    - Avoid setting the modify time on a directory that already has the right
+      modify time set.  This avoids tweaking the dir's ctime.
+
+    - Improved the daemon-exclude handling to do a better job of applying the
+      exclude rules to path entries.  It also sends the user an error just as
+      if the files were actually missing (instead of silently ignoring the
+      user's args), and avoids sending the user the filter-action messages
+      for these non-user-initiated rules.
+
+    - Fixed some glitches with the dry-run code's missing-directory
+      handling, including a problem when combined with --fuzzy.
+
+    - Fixed some glitches with the skipped-directory handling.
+
+    - Fixed the 'T'-flag itemizing of symlinks when --time isn't preserved.
+
+    - Fixed a glitch in the itemizing of permissions with the -E option.
+
+    - The --append option's restricting of transfers to those that add data no
+      longer prevents the updating of non-content changes to otherwise up-to-
+      date files (i.e. those with the same content but differing permissions,
+      ownership, xattrs, etc.).
+
+    - Don't allow --fake-super to be specified with -XX (double --xattrs)
+      because the options conflict.  If a daemon has "fake super" enabled,
+      it automatically downgrades a -XX request to -X.
+
+    - Fixed a couple bugs in the parsing of daemon-config excludes that could
+      make a floating exclude rule get treated as matching an absolute path.
+
+    - A daemon doesn't try to auto-refuse the "iconv" option if iconv-support
+      wasn't compiled in to the daemon (avoiding a warning in the logs).
+
+    - Fixed the inclusion of per-dir merge files from implied dirs.
+
+    - Fixed the support/rrsync script to work with the latest options that
+      rsync sends (including its flag-specifying use of -e to the server).
+
+  ENHANCEMENTS:
+
+    - Added the --old-dirs (--old-d) option to make it easier for a user to
+      ask for file-listings with older rsync versions (this is easier than
+      having to type "-r --exclude='/*/*'" manually).
+
+    - When getting an error while asking an older rsync daemon for a file
+      listing, rsync will try to notice if the error is a rejection of the
+      --dirs (-d) option and let the user know how to work around the issue.
+
+    - Added a few more --no-OPTION overrides.
+
+    - Improved the documentation of the --append option.
+
+    - Improved the documentation of the filter/exclude/include daemon
+      parameters.
+
+  INTERNAL:
+
+    - Fixed a couple minor bugs in the included popt library (ones which I
+      sent to the official popt project for inclusion in the 1.14 release).
+
+    - Fixed a stat() call that should have been do_stat() so that the proper
+      normal/64-bit stat() function gets called.  (Was in an area that should
+      not have caused problems, though.)
+
+    - Changed the file-glob code to do a directory scan without using the
+      "glob" and "glob.h".  This lets us do the globbing with less memory
+      churn, and also avoid adding daemon-excluded items to the returned
+      args.
+
+  DEVELOPER RELATED:
+
+    - The configure script tries to get the user's compiler to not warn about
+      unused function parameters if the build is not including one or more of
+      the ACL/xattrs/iconv features.
+
+    - The configure script now has better checks for figuring out if the
+      included popt code should be used or not.
+
+    - Fixed two testsuite glitches: avoid a failure if someone's "cd" command
+      outputs the current directory when cd-ing to a relative path, and made
+      the itemized test query how rsync was built to determine if it should
+      expect hard-linked symlinks or not.
+
+    - Updated the testsuite to verify that various bug fixes remain fixed.
+
+    - The RPM spec file was updated to have: (1) comments for how to use the
+      rsync-patch tar file, and (2) an /etc/xinetd.d/rsync file.
+
+    - Updated the build scripts to work with a revised FTP directory
+      structure.
+
+
+NEWS for rsync 3.0.0 (1 Mar 2008)
+Protocol: 30 (changed)
+Changes since 2.6.9:
+
+  NOTABLE CHANGES IN BEHAVIOR:
+
+    - The handling of implied directories when using --relative has changed to
+      send them as directories (e.g. no implied dir is ever sent as a symlink).
+      This avoids unexpected behavior and should not adversely affect most
+      people.  If you're one of those rare individuals who relied upon having
+      an implied dir be duplicated as a symlink, you should specify the
+      transfer of the symlink and the transfer of the referent directory as
+      separate args.  (See also --keep-dirlinks and --no-implied-dirs.)
+      Also, exclude rules no longer have a partial effect on implied dirs.
+
+    - Requesting a remote file-listing without specifying -r (--recursive) now
+      sends the -d (--dirs) option to the remote rsync rather than sending -r
+      along with an extra exclude of /*/*.  If the remote rsync does not
+      understand the -d option (i.e. it is 2.6.3 or older), you will need to
+      either turn off -d (--no-d), or specify  -r --exclude='/*/*'  manually.
+
+    - In --dry-run mode, the last line of the verbose summary text is output
+      with a "(DRY RUN)" suffix to help remind you that no updates were made.
+      Similarly, --only-write-batch outputs "(BATCH ONLY)".
+
+    - A writable rsync daemon with "use chroot" disabled now defaults to a
+      symlink-munging behavior designed to make symlinks safer while also
+      allowing absolute symlinks to be stored and retrieved.  This also has
+      the effect of making symlinks unusable while they're in the daemon's
+      hierarchy.  See the daemon's "munge symlinks" parameter for details.
+
+    - Starting up an extra copy of an rsync daemon will not clobber the pidfile
+      for the running daemon -- if the pidfile exists, the new daemon will exit
+      with an error.  This means that your wrapper script that starts the rsync
+      daemon should be made to handle lock-breaking (if you want any automatic
+      breaking of locks to be done).
+
+  BUG FIXES:
+
+    - A daemon with "use chroot = no" and excluded items listed in the daemon
+      config file now properly checks an absolute-path arg specified for these
+      options:  --compare-dest, --link-dest, --copy-dest, --partial-dir,
+      --backup-dir, --temp-dir, and --files-from.
+
+    - A daemon can now be told to disable all user- and group-name translation
+      on a per-module basis.  This avoids a potential problem with a writable
+      daemon module that has "use chroot" enabled -- if precautions weren't
+      taken, a user could try to add a missing library and get rsync to use
+      it.  This makes rsync safer by default, and more configurable when id-
+      translation is not desired.  See the daemon's "numeric ids" parameter
+      for full details.
+
+    - A chroot daemon can now indicate which part of its path should affect the
+      chroot call, and which part should become an inside-chroot path for the
+      module.  This allows you to have outside-the-transfer paths (such as for
+      libraries) even when you enable chroot protection.  The idiom used in the
+      rsyncd.conf file is:  path = /chroot/dirs/./dirs/inside
+
+    - If a file's data arrived successfully on the receiving side but the
+      rename of the temporary file to the destination file failed AND the
+      --remove-source-files (or the deprecated --remove-sent-files) option
+      was specified, rsync no longer erroneously removes the associated
+      source file.
+
+    - Fixed the output of -ii when combined with one of the --*-dest options:
+      it now itemizes all the items, not just the changed ones.
+
+    - Made the output of all file types consistent when using a --*-dest
+      option.  Prior versions would output too many creation events for
+      matching items.
+
+    - The code that waits for a child pid now handles being interrupted by a
+      signal.  This fixes a problem with the pre-xfer exec function not being
+      able to get the exit status from the script.
+
+    - A negated filter rule (i.e. with a '!' modifier) no longer loses the
+      negation when sending the filter rules to the remote rsync.
+
+    - Fixed a problem with the --out-format (aka --log-format) option %f:  it
+      no longer outputs superfluous directory info for a non-daemon rsync.
+
+    - Fixed a problem with -vv (double --verbose) and --stats when "pushing"
+      files (which includes local copies).  Version 2.6.9 would complete the
+      copy, but exit with an error when the receiver output its memory stats.
+
+    - If --password-file is used on a non-daemon transfer, rsync now complains
+      and exits.  This should help users figure out that they can't use this
+      option to control a remote shell's password prompt.
+
+    - Make sure that directory permissions of a newly-created destination
+      directory are handled right when --perms is left off.
+
+    - The itemized output of a newly-created destination directory is now
+      output as a creation event, not a change event.
+
+    - Improved --hard-link so that more corner cases are handled correctly
+      when combined with options such as --link-dest and/or --ignore-existing.
+
+    - The --append option no longer updates a file that has the same size.
+
+    - Fixed a bug when combining --backup and --backup-dir with --inplace:
+      any missing backup directories are now created.
+
+    - Fixed a bug when using --backup and --inplace with --whole-file or
+      --read-batch: backup files are actually created now.
+
+    - The daemon pidfile is checked and created sooner in the startup sequence.
+
+    - If a daemon module's "path" value is not an absolute pathname, the code
+      now makes it absolute internally (making it work properly).
+
+    - Ensure that a temporary file always has owner-write permission while we
+      are writing to it.  This avoids problems with some network filesystems
+      when transfering read-only files.
+
+    - Any errors output about password-file reading no longer cause an error at
+      the end of the run about a partial transfer.
+
+    - The --read-batch option for protocol 30 now ensures that several more
+      options are set correctly for the current batch file:  --iconv, --acls,
+      --xattrs, --inplace, --append, and --append-verify.
+
+    - Using --only-write-batch to a daemon receiver now works properly (older
+      versions would update some files while writing the batch).
+
+    - Avoid outputting a "file has vanished" message when the file is a broken
+      symlink and --copy-unsafe-links or --copy-dirlinks is used (the code
+      already handled this for --copy-links).
+
+    - Fixed the combination of --only-write-batch and --dry-run.
+
+    - Fixed rsync's ability to remove files that are not writable by the file's
+      owner when rsync is running as the same user.
+
+    - When transferring large files, the sender's hashtable of checksums is
+      kept at a more reasonable state of fullness (no more than 80% full) so
+      that the scanning of the hashtable will not bog down as the number of
+      blocks increases.
+
+  ENHANCEMENTS:
+
+    - A new incremental-recursion algorithm is now used when rsync is talking
+      to another 3.x version.  This starts the transfer going more quickly
+      (before all the files have been found), and requires much less memory.
+      See the --recursive option in the manpage for some restrictions.
+
+    - Lowered memory use in the non-incremental-recursion algorithm for typical
+      option values (usually saving from 21-29 bytes per file).
+
+    - The default --delete algorithm is now --delete-during when talking to a
+      3.x rsync.  This is a faster scan than using --delete-before (which is
+      the default when talking to older rsync versions), and is compatible with
+      the new incremental recursion mode.
+
+    - Rsync now allows multiple remote-source args to be specified rather than
+      having to rely on a special space-splitting side-effect of the remote-
+      shell.  Additional remote args must specify the same host or an empty one
+      (e.g. empty:  :file1  or  ::module/file2).  For example, this means that
+      local use of brace expansion now works:  rsync -av host:dir/{f1,f2} .
+
+    - Added the --protect-args (-s) option, that tells rsync to send most of
+      the command-line args at the start of the transfer rather than as args
+      to the remote-shell command.  This protects them from space-splitting,
+      and only interprets basic wildcard special shell characters (*?[).
+
+    - Added the --delete-delay option, which is a more efficient way to delete
+      files at the end of the transfer without needing a separate delete pass.
+
+    - Added the --acls (-A) option to preserve Access Control Lists.  This is
+      an improved version of the prior patch that was available, and it even
+      supports OS X ACLs.  If you need to have backward compatibility with old,
+      ACL-patched versions of rsync, apply the acls.diff file from the patches
+      dir.
+
+    - Added the --xattrs (-X) option to preserve extended attributes.  This is
+      an improved version of the prior patch that was available, and it even
+      supports OS X xattrs (which includes their resource fork data).  If you
+      need to have backward compatibility with old, xattr-patched versions of
+      rsync, apply the xattrs.diff file from the patches dir.
+
+    - Added the --fake-super option that allows a non-super user to preserve
+      all attributes of a file by using a special extended-attribute idiom.
+      It even supports the storing of foreign ACL data on your backup server.
+      There is also an analogous "fake super" parameter for an rsync daemon.
+
+    - Added the --iconv option, which allows rsync to convert filenames from
+      one character-set to another during the transfer.  The default is to
+      make this feature available as long as your system has iconv_open().
+      If compilation fails, specify --disable-iconv to configure, and then
+      rebuild.  If you want rsync to perform character-set conversions by
+      default, you can specify --enable-iconv=CONVERT_STRING with the default
+      value for the --iconv option that you wish to use.  For example,
+      "--enable-iconv=." is a good choice.  See the rsync manpage for an
+      explanation of the --iconv option's settings.
+
+    - A new daemon config parameter, "charset", lets you control the character-
+      set that is used during an --iconv transfer to/from a daemon module.  You
+      can also set your daemon to refuse "no-iconv" if you want to force the
+      client to use an --iconv transfer (requiring an rsync 3.x client).
+
+    - Added the --skip-compress=LIST option to override the default list of
+      file suffixes that will not be compressed when using --compress (-z).
+
+    - The daemon's default for "dont compress" was extended to include:
+	  *.7z *.mp[34] *.mov *.avi *.ogg *.jpg *.jpeg
+      The name-matching routine was also optimized to run more quickly.
+
+    - The --max-delete option now outputs a warning if it skipped any file
+      deletions, including a count of how many deletions were skipped.  (Older
+      versions just silently stopped deleting things.)
+
+    - You may specify --max-delete=0 to a 3.0.0 client to request that it warn
+      about extraneous files without deleting anything.  If you're not sure
+      what version the client is, you can use the less-obvious --max-delete=-1,
+      as both old and new versions will treat that as the same request (though
+      older versions don't warn).
+
+    - The --hard-link option now uses less memory on both the sending and
+      receiving side for all protocol versions.  For protocol 30, the use of a
+      hashtable on the sending side allows us to more efficiently convey to the
+      receiver what files are linked together.  This reduces the amount of data
+      sent over the socket by a considerable margin (rather than adding more
+      data), and limits the in-memory storage of the device+inode information
+      to just the sending side for the new protocol 30, or to the receiving
+      side when speaking an older protocol (note that older rsync versions kept
+      the device+inode information on both sides).
+
+    - The filter rules now support a perishable ("p") modifier that marks rules
+      that should not have an effect in a directory that is being deleted.  e.g.
+      -f '-p .svn/' would only affect "live" .svn directories.
+
+    - Rsync checks all the alternate-destination args for validity (e.g.
+      --link-dest).  This lets the user know when they specified a directory
+      that does not exist.
+
+    - If we get an ENOSYS error setting the time on a symlink, we don't
+      complain about it anymore (for those systems that even support the
+      setting of the modify-time on a symlink).
+
+    - Protocol 30 now uses MD5 checksums instead of MD4.
+
+    - Changed the --append option to not checksum the existing data in the
+      destination file, which speeds up file appending.
+
+    - Added the --append-verify option, which works like the older --append
+      option (verifying the existing data in the destination file).  For
+      compatibility with older rsync versions, any use of --append that is
+      talking protocol 29 or older will revert to the --append-verify method.
+
+    - Added the --contimeout=SECONDS option that lets the user specify a
+      connection timeout for rsync daemon access.
+
+    - Documented and extended the support for the RSYNC_CONNECT_PROG variable
+      that can be used to enhance the client side of a daemon connection.
+
+    - Improved the dashes and double-quotes in the nroff manpage output.
+
+    - Rsync now supports a lot more --no-OPTION override options.
+
+  INTERNAL:
+
+    - The file-list sorting algorithm now uses a sort that keeps any same-
+      named items in the same order as they were specified.  This allows
+      rsync to always ensure that the first of the duplicates is the one
+      that will be included in the copy.  The new sort is also faster
+      than the glibc version of qsort() and mergesort().
+
+    - Rsync now supports the transfer of 64-bit timestamps (time_t values).
+
+    - Made the file-deletion code use a little less stack when recursing
+      through a directory hierarchy of extraneous files.
+
+    - Fixed a build problem with older (2.x) versions of gcc.
+
+    - Added some isType() functions that make dealing with signed characters
+      easier without forcing variables via casts.
+
+    - Changed strcat/strcpy/sprintf function calls to use safer versions.
+
+    - Upgraded the included popt version to 1.10.2 and improved its use of
+      string-handling functions.
+
+    - Added missing prototypes for compatibility functions from the lib dir.
+
+    - Configure determines if iconv() has a const arg, allowing us to avoid a
+      compiler warning.
+
+    - Made the sending of some numbers more efficient for protocol 30.
+
+    - Make sure that a daemon process doesn't mind if the client was weird and
+      omitted the --server option.
+
+    - There are more internal logging categories available in protocol 30 than
+      the age-old FINFO and FERROR, including FERROR_XFER and FWARN.  These new
+      categories allow some errors and warnings to go to stderr without causing
+      an erroneous end-of-run warning about some files not being able to be
+      transferred.
+
+    - Improved the use of "const" on pointers.
+
+    - Improved J.W.'s pool_alloc routines to add a way of incrementally freeing
+      older sections of a pool's memory.
+
+    - The getaddrinfo.c compatibility code in the "lib" dir was replaced with
+      some new code (derived from samba, derived from PostgreSQL) that has a
+      better license than the old code.
+
+  DEVELOPER RELATED:
+
+    - Rsync is now licensed under the GPLv3 or later.
+
+    - Rsync is now being maintained in a "git" repository instead of CVS
+      (though the old CVS repository still exists for historical access).
+      Several maintenance scripts were updated to work with git.
+
+    - Generated files are no longer committed into the source repository.  The
+      autoconf and autoheader commands are now automatically run during the
+      normal use of "configure" and "make".  The latest dev versions of all
+      generated files can also be copied from the samba.org web site (see the
+      prepare-source script's fetch option).
+
+    - The "patches" directory of diff files is now built from branches in the
+      rsync git repository (branch patch/FOO creates file patches/FOO.diff).
+      This directory is now distributed in a separate separate tar file named
+      rsync-patches-VERSION.tar.gz instead of the main rsync-VERSION.tar.gz.
+
+    - The proto.h file is now built using a simple perl script rather than a
+      complex awk script, which proved to be more widely compatible.
+
+    - When running the tests, we now put our per-test temp dirs into a sub-
+      directory named testtmp (which is created, if missing).  This allows
+      someone to symlink the testtmp directory to another filesystem (which is
+      useful if the build dir's filesystem does not support ACLs and xattrs,
+      but another filesystem does).
+
+    - Rsync now has a way of handling protocol-version changes during the
+      development of a new protocol version.  This causes any out-of-sync
+      versions to speak an older protocol rather than fail in a cryptic manner.
+      This addition makes it safer to deploy a pre-release version that may
+      interact with the public.  This new exchange of sub-version info does not
+      interfere with the {MIN,MAX}_PROTOCOL_VERSION checking algorithm (which
+      does not have enough range to allow the main protocol number to be
+      incremented for every minor tweak in that happens during development).
+
+    - The csprotocol.txt file was updated to mention the daemon protocol change
+      in the 3.0.0 release.

 WHAT IS RSYNC?
 --------------
 
-rsync is a replacement for scp/rcp that has many more features.
+Rsync is a fast and extraordinarily versatile file copying tool for
+both remote and local files.
 
-rsync uses the "rsync algorithm" which provides a very fast method for

 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.
-At first glance this may seem impossible because the calculation of
-diffs between two files normally requires local access to both

+
+When this parameter is enabled, rsync will not attempt to map users and groups
+by name (by default), but instead copy IDs as though bf(--numeric-ids) had
+been specified.  In order to enable name-mapping, rsync needs to be able to
 use the standard library functions for looking up names and IDs (i.e.

+If you copy the necessary resources into the module's chroot area, you

+
+dit(bf(numeric ids)) Enabling this parameter disables the mapping
+of users and groups by name for the current daemon module.  This prevents
+the daemon from trying to load any user/group-related files or libraries.
+This enabling makes the transfer behave as if the client had passed
+the bf(--numeric-ids) command-line option.  By default, this parameter is
+enabled for chroot modules and disabled for non-chroot modules.

+
+dit(bf(munge symlinks)) This parameter tells rsync to modify
+all incoming symlinks in a way that makes them unusable but recoverable
+(see below).  This should help protect your files from user trickery when
+your daemon module is writable.  The default is disabled when "use chroot"
+is on and the inside-chroot path is "/", otherwise it is enabled.
+
+If you disable this parameter on a daemon that is not read-only, there
+are tricks that a user can play with uploaded symlinks to access
+daemon-excluded items (if your module has any), and, if "use chroot"
+is off, rsync can even be tricked into showing or changing data that
+is outside the module's path (as access-permissions allow).
+
+The way rsync disables the use of symlinks is to prefix each one with
+the string "/rsyncd-munged/".  This prevents the links from being used
+as long as that directory does not exist.  When this parameter is enabled,
+rsync will refuse to run if that path is a directory or a symlink to
+a directory.  When using the "munge symlinks" parameter in a chroot area
+that has an inside-chroot path of "/", you should add "/rsyncd-munged/"
+to the exclude setting for the module so that
+a user can't try to create it.
+
+Note:  rsync makes no attempt to verify that any pre-existing symlinks in
+the module's hierarchy are as safe as you want them to be (unless, of
+course, it just copied in the whole hierarchy).  If you setup an rsync
+daemon on a new area or locally add symlinks, you can manually protect your
+symlinks from being abused by prefixing "/rsyncd-munged/" to the start of
+every symlink's value.  There is a perl script in the support directory
+of the source code named "munge-symlinks" that can be used to add or remove
+this prefix from your symlinks.
+
+When this parameter is disabled on a writable module and "use chroot" is off
+(or the inside-chroot path is not "/"),
+incoming symlinks will be modified to drop a leading slash and to remove ".."
+path elements that rsync believes will allow a symlink to escape the module's
+hierarchy.  There are tricky ways to work around this, though, so you had
+better trust your users if you choose this combination of parameters.
+
+dit(bf(charset)) This specifies the name of the character set in which the
+module's filenames are stored.  If the client uses an bf(--iconv) option,
+the daemon will use the value of the "charset" parameter regardless of the
+character set the client actually passed.  This allows the daemon to
+support charset conversion in a chroot module without extra files in the
+chroot area, and also ensures that name-translation is done in a consistent
+manner.  If the "charset" parameter is not set, the bf(--iconv) option is
+refused, just as if "iconv" had been specified via "refuse options".
+
+If you wish to force users to always use bf(--iconv) for a particular
