 423 <div class="sectionbody">
 424 <div class="paragraph"><p>This script is used to combine all objects that do not currently
 425 reside in a "pack", into a pack.  It can also be used to re-organize
 426 existing packs into a single, more efficient pack.</p></div>
 427 <div class="paragraph"><p>A pack is a collection of objects, individually compressed, with
 428 delta compression applied, stored in a single file, with an
 429 associated index file.</p></div>
 430 <div class="paragraph"><p>Packs are used to reduce the load on mirror systems, backup
 431 engines, disk storage, etc.</p></div>

 439 <dd>
 440 <p>
 441         Instead of incrementally packing the unpacked objects,
 442         pack everything referenced into a single pack.
 443         Especially useful when packing a repository that is used
 444         for private development. Use
 445         with <em>-d</em>.  This will clean up the objects that <tt>git prune</tt>
 446         leaves behind, but <tt>git fsck --full</tt> shows as
 447         dangling.
 448 </p>
 449 <div class="paragraph"><p>Note that users fetching over dumb protocols will have to fetch the
 450 whole new pack in order to get any contained object, no matter how many
 451 other objects in that pack they already have locally.</p></div>

 453 <dt class="hdlist1">

 456 <dd>
 457 <p>
 458         Same as <tt>-a</tt>, unless <em>-d</em> is used.  Then any unreachable
 459         objects in a previous pack become loose, unpacked objects,
 460         instead of being left in the old pack.  Unreachable objects
 461         are never intentionally added to a pack, even when repacking.
 462         This option prevents unreachable objects from being immediately
 463         deleted by way of being left in the old pack and then
 464         removed.  Instead, the loose unreachable objects
 465         will be pruned according to normal expiry rules
 466         with the next <em>git gc</em> invocation. See <a href="git-gc.html">git-gc(1)</a>.

 474         After packing, if the newly created packs make some

 476         Also run  <em>git prune-packed</em> to remove redundant
 477         loose object files.

 521         Do not update the server information with
 522         <em>git update-server-info</em>.  This option skips
 523         updating local catalog files needed to publish
 524         this repository (or a direct copy of it)
 525         over HTTP or FTP.  See <a href="git-update-server-info.html">git-update-server-info(1)</a>.

 535 <p>
 536         These two options affect how the objects contained in the pack are
 537         stored using delta compression. The objects are first internally
 538         sorted by type, size and optionally names and compared against the
 539         other objects within <tt>--window</tt> to see if using delta compression saves
 540         space. <tt>--depth</tt> limits the maximum delta depth; making it too deep
 541         affects the performance on the unpacker side, because delta data needs
 542         to be applied that many times to get to the necessary object.
 543         The default value for --window is 10 and --depth is 50.

 550 <p>
 551         This option provides an additional limit on top of <tt>--window</tt>;
 552         the window size will dynamically scale down so as to not take
 553         up more than <em>&lt;n&gt;</em> bytes in memory.  This is useful in
 554         repositories with a mix of large and small objects to not run
 555         out of memory with a large window, but still be able to take
 556         advantage of the large window for the smaller objects.  The
 557         size can be suffixed with "k", "m", or "g".
 558         <tt>--window-memory=0</tt> makes memory usage unlimited, which is the
 559         default.

 569         If specified,  multiple packfiles may be created.

 579 <em>git pack-objects</em>; this typically results in slightly smaller packs,
 580 but the generated packs are incompatible with versions of Git older than
 581 version 1.4.4. If you need to share your repository with such ancient Git
 582 versions, either directly or via the dumb http or rsync protocol, then you
 583 need to set the configuration variable <tt>repack.UseDeltaBaseOffset</tt> to
 584 "false" and repack. Access from old Git versions over the native protocol
 585 is unaffected by this option as the conversion is performed on the fly
 586 as needed in that case.</p></div>
