pack.deltaCacheLimit::
The maximum size of a delta, that is cached in
linkgit:git-pack-objects[1]. This cache is used to speed up the
writing object phase by not having to recompute the final delta
result once the best match for all objects is found.
Defaults to 1000. Maximum value is 65535.
pack.threads::
Specifies the number of threads to spawn when searching for best
delta matches. This requires that linkgit:git-pack-objects[1]
be compiled with pthreads otherwise this option is ignored with a
warning. This is meant to reduce packing time on multiprocessor
machines. The required amount of memory for the delta search window
is however multiplied by the number of threads.
Specifying 0 will cause Git to auto-detect the number of CPUs
and set the number of threads accordingly.
pack.indexVersion::
Specify the default pack index version. Valid values are 1 for
legacy pack index used by Git versions prior to 1.5.2, and 2 for
the new pack index with capabilities for packs larger than 4 GB
as well as proper protection against the repacking of corrupted
packs. Version 2 is the default. Note that version 2 is enforced
and this config option is ignored whenever the corresponding pack is
larger than 2 GB.
+
If you have an old Git that does not understand the version 2 `*.idx` file,
cloning or fetching over a non-native protocol (e.g. "http")
that will copy both `*.pack` file and corresponding `*.idx` file from the
other side may give you a repository that cannot be accessed with your
older version of Git. If the `*.pack` file is smaller than 2 GB, however,
you can use linkgit:git-index-pack[1] on the *.pack file to regenerate
the `*.idx` file.
pack.packSizeLimit::
The maximum size of a pack. This setting only affects
packing to a file when repacking, i.e. the git:// protocol
is unaffected. It can be overridden by the `--max-pack-size`
option of linkgit:git-repack[1]. Reaching this limit results
in the creation of multiple packfiles.
+
Note that this option is rarely useful, and may result in a larger total
on-disk size (because Git will not store deltas between packs) and
worse runtime performance (object lookup within multiple packs is
slower than a single pack, and optimizations like reachability bitmaps
cannot cope with multiple packs).
+
If you need to actively run Git using smaller packfiles (e.g., because your
filesystem does not support large files), this option may help. But if
your goal is to transmit a packfile over a medium that supports limited
sizes (e.g., removable media that cannot store the whole repository),
you are likely better off creating a single large packfile and splitting
it using a generic multi-volume archive tool (e.g., Unix `split`).
+
The minimum size allowed is limited to 1 MiB. The default is unlimited.
Common unit suffixes of 'k', 'm', or 'g' are supported.
pack.useBitmaps::
When true, git will use pack bitmaps (if available) when packing
to stdout (e.g., during the server side of a fetch). Defaults to
true. You should not generally need to turn this off unless
you are debugging pack bitmaps.
pack.useBitmapBoundaryTraversal::
When true, Git will use an experimental algorithm for computing
reachability queries with bitmaps. Instead of building up
complete bitmaps for all
