-      careful about reading integers from the network.
+    - The letter 'D' in the itemized output was being used for both devices
+      (character or block) as well as other special files (such as fifos and
+      named sockets).  This has changed to separate non-device special files
+      under the 'S' designation (e.g. "cS+++++++ path/fifo").  See also the
+      "--specials" option, below.
+
+    - The way rsync escapes unreadable characters has changed.  First, rsync
+      now has support for recognizing valid multibyte character sequences in
+      your current locale, allowing it to escape fewer characters than before
+      for a locale such as UTF-8.  Second, it now uses an escape idiom of
+      "\#123", which is the literal string "\#" followed by exactly 3 octal
+      digits.  Rsync no longer doubles a backslash character in a filename
+      (e.g. it used to output "foo\\bar" when copying "foo\bar") -- now it only
+      escapes a backslash that is followed by a hash-sign and 3 digits (0-9)
+      (e.g. it will output "foo\#134#789" when copying "foo\#789").  See also
+      the --8-bit-output (-8) option, mentioned below.
+
+      Script writers: the local rsync is the one that outputs escaped names,
+      so if you need to support unescaping of filenames for older rsyncs, I'd
+      suggest that you parse the output of "rsync --version" and only use the
+      old unescaping rules for 2.6.5 and 2.6.6.
 
   BUG FIXES:
 
-    * Fix possible string mangling in log files.
+    - Fixed a really old bug that caused --checksum (-c) to checksum all the
+      files encountered during the delete scan (ouch).
 
-    * Fix for setting local address of outgoing sockets.
+    - Fixed a potential hang in a remote generator:  when the receiver gets a
+      read-error on the socket, it now signals the generator about this so that
+      the generator does not try to send any of the terminating error messages
+      to the client (avoiding a potential hang in some setups).
 
-    * Better handling of hardlinks and devices on platforms with
-      64-bit dev_t or ino_t.
+    - Made hard-links work with symlinks and devices again.
 
-    * Name resolution on machines supporting IPv6 is improved.
+    - If the sender gets an early EOF reading a source file, we propagate this
+      error to the receiver so that it can discard the file and try requesting
+      it again (which is the existing behavior for other kinds of read errors).
 
-    * Fix for device nodes.  (dann frazier)   (Debian #129135)
+    - If a device-file/special-file changes permissions, rsync now updates the
+      permissions without recreating the file.
+
+    - If the user specifies a remote-host for both the source and destination,
+      we now output a syntax error rather than trying to open the destination
+      hostspec as a filename.
+
+    - When --inplace creates a new destination file, rsync now creates it with
+      permissions 0600 instead of 0000 -- this makes restarting possible when
+      the transfer gets interrupted in the middle of sending a new file.
+
+    - Reject the combination of --inplace and --sparse since the sparse-output
+      algorithm doesn't work when overwriting existing data.
+
+    - Fixed the directory name in the error that is output when pop_dir()
+      fails.
+
+    - Really fixed the parsing of a "!" entry in .cvsignore files this time.
+
+    - If the generator gets a stat() error on a file, output it (this used to
+      require at least -vv for the error to be seen).
+
+    - If waitpid() fails or the child rsync didn't exit cleanly, we now handle
+      the exit status properly and generate a better error.
+
+    - Fixed some glitches in the double-verbose output when using --copy-dest,
+      --link-dest, or --compare-dest.  Also improved how the verbose output
+      handles hard-links (within the transfer) that had an up-to-date alternate
+      "dest" file, and copied files (via --copy-dest).
+
+    - Fixed the matching of the dont-compress items (e.g. *.gz) against files
+      that have a path component containing a slash.
+
+    - If code reading a filter/exclude file an EINTR error, rsync now clears
+      the error flag on the file handle so it can keep on reading.
+
+    - If --relative is active, the sending side cleans up trailing "/" or "/."
+      suffixes to avoid triggering a bug in older rsync versions.  Also, we now
+      reject a ".." dir if it would be sent as a relative dir.
+
+    - If a non-directory is in the way of a directory and rsync is run with
+      --dry-run and --delete, rsync no longer complains about not being able
+      to opendir() the not-yet present directory.
+
+    - Got rid of the need for --force to be used in some circumstances with
+      --delete-after (making it consistent with --delete-before/-during).
+
+    - Rsync now ignores the SIGXFSZ signal, just in case your OS sends this
+      when a file is too large (rsync handles the write error).
 
   ENHANCEMENTS:
 
-    * With -v, rsync now shows the command used to initiate an ssh/rsh
-      connection.
+    - Added the --append option that makes rsync append data onto files that
+      are longer on the source than the destination (this includes new files).
 
-    * --statistics now shows memory heap usage on platforms that
-        support mallinfo().
+    - Added the --min-size=SIZE option to exclude small files from the
+      transfer.
 
-    * "The Ted T'so school of program optimization": make progress
-      visible and people will think it's faster.  (With --progress,
-      rsync will show you how many files it has seen as it builds the
-      file_list, giving some indication that it has not hung.)
+    - Added the --compress-level option to allow you to set how aggressive
+      rsync's compression should be (this option implies --compress).
 
-    * Improvements to batch mode support.  This is still experimental
-      but testing would be welcome.   (Jos Backus)
- 
-    * New --ignore-existing option, patch previously distributed with
-      Vipul's Razor.  (Debian #124286)
+    - Enhanced the parsing of the SIZE value for --min-size and --max-size to
+      allow easy entry of multiples of 1000 (instead of just multiples of 1024)
+      and off-by-one values too (e.g. --max-size=8mb-1).
+
+    - Added the --8-bit-output (-8) option, which tells rsync to avoid escaping
+      high-bit characters that it thinks are unreadable in the current locale.
+
+    - The new option --human-readable (-h) changes the output of --progress,
+      --stats, and the end-of-run summary to be easier to read.  If repeated,
+      the units become powers of 1024 instead of powers of 1000.  (The old
+      meaning of -h, as a shorthand for --help, still works as long as you
+      just use it on its own, as in "rsync -h".)
+
+    - If lutimes() and/or lchmod() are around, use them to allow the
+      preservation of attributes on symlinks.
+
+    - The --link-dest option now affects symlinks and devices (when possible).
+
+    - Added two config items to the rsyncd.conf parsing:  "pre-xfer exec" and
+      "post-xfer exec".  These allow a command to be specified on a per-module
+      basis that will be run before and/or after a daemon-mode transfer.  (See
+      the man page for a list of the environment variables that are set with
+      information about the transfer.)
+
+    - When using the --relative option, you can now insert a dot dir in
+      the source path to indicate where the replication of the source dirs
+      should start.  For example, if you specify a source path of
+      rsync://host/module/foo/bar/./baz/dir with -R, rsync will now only
+      replicate the "baz/dir" part of the source path (note: a trailing
+      dot dir is unaffected unless it also has a trailing slash).
+
+    - Added some new --no-FOO options that make it easier to override unwanted
+      implied or default options.  For example, "-a --no-o" (aka "--archive
+      --no-owner") can be used to turn off the preservation of file ownership
+      that is implied by -a.
+
+    - Added the --chmod=MODE option that allows the destination permissions to
+      be changed from the source permissions.  E.g. --chmod=g+w,o-rwx
+
+    - Added the "incoming chmod" and "outgoing chmod" daemon options that allow
+      a module to specify what permissions changes should be applied to all
+      files copied to and from the daemon.
+
+    - Allow the --temp-dir option to be specified when starting a daemon, which
+      sets the default temporary directory for incoming files.
+
+    - If --delete is combined with --dirs without --recursive, rsync will now
+      delete in any directory whose content is being synchronized.
+
+    - If --backup is combined with --delete without --backup-dir (and without
+      --delete-excluded), we add a "protect" filter-rule to ensure that files
+      with the backup suffix are not deleted.
+
+    - The file-count stats that are output by --progress were improved to
+      better indicate what the numbers mean.  For instance, the output:
+      "(xfer#5, to-check=8383/9999)" indicates that this was the fifth file
+      to be transferred, and we still need to check 8383 more files out of
+      a total of 9999.
+
+    - The include/exclude code now allows a dir/*** directive (with 3 trailing
+      stars) to match both the dir itself as well as all the content below the
+      dir (dir/** would not match the dir).
+
+    - Added the --prune-empty-dirs (-m) option that makes the receiving rsync
+      discard empty chains of directories from the file-list.  This makes it
+      easier to selectively copy files from a source hierarchy and end up with
+      just the directories needed to hold the resulting files.
+
+    - If the --itemize-changes (-i) option is repeated, rsync now includes
+      unchanged files in the itemized output (similar to -vv, but without all
+      the other verbose messages that can get in the way).  Of course, the
+      client must be version 2.6.7 for this to work, but the remote rsync only
+      needs to be 2.6.7 if you're pushing files.
+
+    - Added the --specials option to tell rsync to copy non-device special
+      files (which rsync now attempts even as a normal user).  The --devices
+      option now requests the copying of just devices (character and block).
+      The -D option still requests both (e.g. --devices and --specials), -a
+      still implies -D, and non-root users still get a silent downgrade that
+      omits device copying.
+
+    - Added the --super option to make the receiver always attempt super-user
+      activities.  This is useful for systems that allow things such as devices
+      to be created or ownership to be set without being UID 0, and is also
+      useful for someone who wants to ensure that errors will be output if the
+      receiving rsync isn't being run as root.
+
+    - Added the --sockopts option for those few who want to customize the TCP
+      options used to contact a daemon rsync.
+
+    - Added a way for the --temp-dir option to be combined with a partial-dir
+      setting that lets rsync avoid non-atomic updates (for those times when
+      --temp-dir is not being used because space is tight).
+
+    - A new support script, files-to-excludes, will transform a list of files
+      into a set of include/exclude directives that will copy those files.
+
+    - A new option, --executability (-E) can be used to preserve just the
+      execute bit on files, for those times when using the --perms option is
+      not desired.
+
+    - The daemon now logs each module-list request it receives.
+
+    - New log-format options: %M (modtime), %U (uid), %G (gid), and %B
+      (permission bits, e.g. "rwxr-xrwt").
+
+    - The --dry-run option no longer forces the enabling of --verbose.
+
+    - The --remove-sent-files option now does a better job of incrementally
+      removing the sent files on the sending side (older versions tended to
+      clump up all the removals at the end).
+
+    - Various documentation improvements, including: a better synopsis, some
+      improved examples, a better discussion of the presence and absence of
+      --perms (including how it interacts with the new --executability and
+      --chmod options), an extended discussion of --temp-dir, an improved
+      discussion of --partial-dir, a better description of rsync's pattern
+      matching characters, and the documenting of what the various items in
+      the --stats output mean.
+
+    - Various new and updated diffs in the patches dir, including: acls.diff,
+      xattrs.diff, atimes.diff, detect-renamed.diff, and slp.diff.
+
+  INTERNAL:
+
+    - We now use sigaction() and sigprocmask() if possible, and fall back on
+      signal() if not.  Using sigprocmask() ensures that rsync enables all the
+      signals that it needs, just in case it was started in a masked state.
+
+    - Some buffer sizes were expanded a bit, particularly on systems where
+      MAXPATHLEN is overly small (e.g. cygwin).
+
+    - If io_printf() tries to format more data than fits in the buffer, exit
+      with an error instead of transmitting a truncated buffer.
+
+    - If a va_copy macro is defined, lib/snprintf.c will use it when defining
+      the VA_COPY macro.
+
+    - Reduced the amount of stack memory needed for each level of directory
+      recursion by nearly MAXPATHLEN bytes.
+
+    - The wildmatch function was extended to allow an array of strings to be
+      supplied as the string to match.  This allows the exclude code to do less
+      string copying.
+
+    - Got rid of the safe_fname() function (and all the myriad calls) and
+      replaced it with a new function in the log.c code that filters all the
+      output going to the terminal.
+
+    - Unified the f_name() and the f_name_to() functions.
+
+  DEVELOPER RELATED:
+
+    - The diffs in the patches dir now require "patch -p1 <DIFF" instead of
+      the previous -p0.  Also, the version included in the release tar now
+      affect generated files (e.g. configure, rsync.1, proto.h, etc.), so
+      it is no longer necessary to run autoconf and/or yodl unless you're
+      applying a patch that was checked out from CVS.
+
+    - Several diffs in the patches dir now use the proper --enable-FOO
+      configure option instead of --with-FOO to turn on the inclusion of
+      the newly patched feature.
+
+    - There is a new script, "prepare-source" than can be used to update the
+      various generated files (proto.h, configure, etc.) even before configure
+      has created the Makefile (this is mainly useful when patching the source
+      with a patch that doesn't affect generated files).
+
+    - The testsuite now sets HOME so that it won't be affected by a file such
+      as ~/.popt.

-Handling duplicate names
+Allow supplementary groups in rsyncd.conf			2002/04/09
 
-  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.
+  Perhaps allow supplementary groups to be specified in rsyncd.conf;
+  then make the first one the primary gid and all the rest be
+  supplementary gids.
 
-  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.

-Memory accounting
+Handling IPv6 on old machines
 
-  At exit, show how much memory was used for the file list, etc.
+  The KAME IPv6 patch is nice in theory but has proved a bit of a
+  nightmare in practice.  The basic idea of their patch is that rsync
+  is rewritten to use the new getaddrinfo()/getnameinfo() interface,
+  rather than gethostbyname()/gethostbyaddr() as in rsync 2.4.6.
+  Systems that don't have the new interface are handled by providing
+  our own implementation in lib/, which is selectively linked in.
 
-  Also we do a wierd exponential-growth allocation in flist.c.  I'm
-  not sure this makes sense with modern mallocs.  At any rate it will
-  make us allocate a huge amount of memory for large file lists.
+  The problem with this is that it is really hard to get right on
+  platforms that have a half-working implementation, so redefining
+  these functions clashes with system headers, and leaving them out
+  breaks.  This affects at least OSF/1, RedHat 5, and Cobalt, which
+  are moderately improtant.
+
+  Perhaps the simplest solution would be to have two different files
+  implementing the same interface, and choose either the new or the
+  old API.  This is probably necessary for systems that e.g. have
+  IPv6, but gethostbyaddr() can't handle it.  The Linux manpage claims
+  this is currently the case.
+
+  In fact, our internal sockets interface (things like
+  open_socket_out(), etc) is much narrower than the getaddrinfo()
+  interface, and so probably simpler to get right.  In addition, the
+  old code is known to work well on old machines.
+
+  We could drop the rather large lib/getaddrinfo files.

-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.

+DEVELOPMENT --------------------------------------------------------
+
+Handling duplicate names
+
+  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).

+    - avoids people breaking rsync by trying to do this themselves and
+      messing up
+
+  Should we ship zlib for systems that don't have it, or require
+  people to install it separately?
+
+  Apparently this will make us incompatible with versions of rsync
+  that use the patched version of rsync.  Probably the simplest way to
+  do this is to just disable gzip (with a warning) when talking to old

+Handling the rsync SGML documentation
+
+rsync documentation is now primarily in Docbook format.  Docbook is an
+SGML/XML documentation format that is becoming standard on free
+operating systems.  It's also used for Samba documentation.
+
+The SGML files are source code that can be translated into various
+useful output formats, primarily PDF, HTML, Postscript and plain text.  
+
+To do this transformation on Debian, you should install the
+docbook-utils package.  Having done that, you can say 
+
+  docbook2pdf rsync.sgml
+
+and so on.
+
+On other systems you probably need James Clark's "sp" and "JadeTeX"
+packages.  Work it out for yourself and send a note to the mailing
+list.

+	<question>
+	  <para>Is rsync useful for a single large file like an ISO image?</para>
+	</question>
+	<answer>
+	  <para>
+	    Yes, but note the following:
+
+	  <para>
+   Background: A common use of rsync is to update a file (or set of files) in one location from a more
+   correct or up-to-date copy in another location, taking advantage of portions of the files that are
+   identical to speed up the process. (Note that rsync will transfer a file in its entirety if no copy
+   exists at the destination.)
+
+	  <para>
+   (This discussion is written in terms of updating a local copy of a file from a correct file in a
+   remote location, although rsync can work in either direction.)
+
+	  <para>
+   The file to be updated (the local file) must be in a destination directory that has enough space for
+   two copies of the file. (In addition, keep an extra copy of the file to be updated in a different
+   location for safety -- see the discussion (below) about rsync's behavior when the rsync process is
+   interrupted before completion.)
+
+	  <para>
+   The local file must have the same name as the remote file being sync'd to (I think?). If you are
+   trying to upgrade an iso from, for example, beta1 to beta2, rename the local file to the same name
+   as the beta2 file. *(This is a useful thing to do -- only the changed portions will be
+   transmitted.)*
+
+	  <para>
+   The extra copy of the local file kept in a different location is because of rsync's behavior if
+   interrupted before completion:
+
+	  <para>
+   * If you specify the --partial option and rsync is interrupted, rsync will save the partially
+   rsync'd file and throw away the original local copy. (The partially rsync'd file is correct but
+   truncated.) If rsync is restarted, it will not have a local copy of the file to check for duplicate
+   blocks beyond the section of the file that has already been rsync'd, thus the remainder of the rsync
+   process will be a "pure transfer" of the file rather than taking advantage of the rsync algorithm.
+
+	  <para>
+   * If you don't specify the --partial option and rsync is interrupted, rsync will throw away the
+   partially rsync'd file, and, when rsync is restarted starts the rsync process over from the
+   beginning.
+
+	  <para>
+   Which of these is most desirable depends on the degree of commonality between the local and remote
+   copies of the file *and how much progress was made before the interruption*.
+
+	  <para>
+   The ideal approach after an interruption would be to create a new file by taking the original file
+   and deleting a portion equal in size to the portion already rsync'd and then appending *the
+   remaining* portion to the portion of the file that has already been rsync'd. (There has been some
+   discussion about creating an option to do this automatically.)
+
+   The --compare-dest option is useful when transferring multiple files, but is of no benefit in
+   transferring a single file. (AFAIK)

+.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()

-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.

+rooted in the module's "path" dir, just as if chroot was specified).
+The default for "use chroot" is true.
+
+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
+process in the chroot namespace will need to have access to the resources

+able to copy the IDs, just as if the bf(--numeric-ids) option had been
+specified.
+
+Note that you are free to setup user/group information in the chroot area
+differently from your normal system.  For example, you could abbreviate
+the list of users and groups.  Also, you can protect this information from
+being downloaded/uploaded by adding an exclude rule to the rsyncd.conf file
+(e.g. "exclude = /etc/**").  Note that having the exclusion affect uploads
+is a relatively new feature in rsync, so make sure your daemon is
+at least 2.6.3 to effect this.  Also note that it is safest to exclude a
+directory and all its contents combining the rule "/some/dir/" with the

+merge files are included in the transfer).
 
-Note that this option is not designed with strong security in

+comma-separated chmod strings that will affect the permissions of all
+incoming files (files that are being received by the daemon).  These
+changes happen after any user-requested changes the client requested via
+bf(--chmod).  Note, however, the if the client didn't specify bf(--perms),

+
+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 "/".
