DESCRIPTION
-----------
This script is used to combine all objects that do not currently
-reside in a "pack", into a pack.
+reside in a "pack", into a pack. It can also be used to re-organize
+existing packs into a single, more efficient pack.
A pack is a collection of objects, individually compressed, with
delta compression applied, stored in a single file, with an
-a::
Instead of incrementally packing the unpacked objects,
- pack everything available into a single pack.
+ pack everything referenced into a single pack.
Especially useful when packing a repository that is used
- for private development and there is no need to worry
- about people fetching via dumb file transfer protocols
- from it. Use with '-d'.
+ for private development. Use
+ with '-d'. This will clean up the objects that `git prune`
+ leaves behind, but `git fsck --full` shows as
+ dangling.
++
+Note that users fetching over dumb protocols will have to fetch the
+whole new pack in order to get any contained object, no matter how many
+other objects in that pack they already have locally.
+
+-A::
+ Same as `-a`, unless '-d' is used. Then any unreachable
+ objects in a previous pack become loose, unpacked objects,
+ instead of being left in the old pack. Unreachable objects
+ are never intentionally added to a pack, even when repacking.
+ This option prevents unreachable objects from being immediately
+ deleted by way of being left in the old pack and then
+ removed. Instead, the loose unreachable objects
+ will be pruned according to normal expiry rules
+ with the next 'git-gc' invocation. See linkgit:git-gc[1].
-d::
After packing, if the newly created packs make some
existing packs redundant, remove the redundant packs.
- Also runs gitlink:git-prune-packed[1].
+ Also run 'git-prune-packed' to remove redundant
+ loose object files.
-l::
- Pass the `--local` option to `git pack-objects`, see
- gitlink:git-pack-objects[1].
+ Pass the `--local` option to 'git-pack-objects'. See
+ linkgit:git-pack-objects[1].
-f::
- Pass the `--no-reuse-delta` option to `git pack-objects`, see
- gitlink:git-pack-objects[1].
+ Pass the `--no-reuse-object` option to `git-pack-objects`, see
+ linkgit:git-pack-objects[1].
-q::
- Pass the `-q` option to `git pack-objects`, see
- gitlink:git-pack-objects[1].
+ Pass the `-q` option to 'git-pack-objects'. See
+ linkgit:git-pack-objects[1].
-n::
- Do not update the server information with
- `git update-server-info`.
-
---window=[N], --depth=[N]::
+ Do not update the server information with
+ 'git-update-server-info'. This option skips
+ updating local catalog files needed to publish
+ this repository (or a direct copy of it)
+ over HTTP or FTP. See linkgit:git-update-server-info[1].
+
+--window=[N]::
+--depth=[N]::
These two options affect how the objects contained in the pack are
stored using delta compression. The objects are first internally
sorted by type, size and optionally names and compared against the
space. `--depth` limits the maximum delta depth; making it too deep
affects the performance on the unpacker side, because delta data needs
to be applied that many times to get to the necessary object.
- The default value for both --window and --depth is 10.
+ The default value for --window is 10 and --depth is 50.
+
+--window-memory=[N]::
+ This option provides an additional limit on top of `--window`;
+ the window size will dynamically scale down so as to not take
+ up more than N bytes in memory. This is useful in
+ repositories with a mix of large and small objects to not run
+ out of memory with a large window, but still be able to take
+ advantage of the large window for the smaller objects. The
+ size can be suffixed with "k", "m", or "g".
+ `--window-memory=0` makes memory usage unlimited, which is the
+ default.
+
+--max-pack-size=<n>::
+ Maximum size of each output packfile, expressed in MiB.
+ If specified, multiple packfiles may be created.
+ The default is unlimited.
Configuration
When configuration variable `repack.UseDeltaBaseOffset` is set
for the repository, the command passes `--delta-base-offset`
-option to `git-pack-objects`; this typically results in slightly
+option to 'git-pack-objects'; this typically results in slightly
smaller packs, but the generated packs are incompatible with
versions of git older than (and including) v1.4.3; do not set
the variable in a repository that older version of git needs to
