pack.window::
The size of the window used by linkgit:git-pack-objects[1] when no
window size is given on the command line. Defaults to 10.
pack.depth::
The maximum delta depth used by linkgit:git-pack-objects[1] when no
maximum depth is given on the command line. Defaults to 50.
Maximum value is 4095.
pack.windowMemory::
The maximum size of memory that is consumed by each thread
in linkgit:git-pack-objects[1] for pack window memory when
no limit is given on the command line. The value can be
suffixed with "k", "m", or "g". When left unconfigured (or
set explicitly to 0), there will be no limit.
pack.compression::
An integer -1..9, indicating the compression level for objects
in a pack file. -1 is the zlib default. 0 means no
compression, and 1..9 are various speed/size tradeoffs, 9 being
slowest. If not set, defaults to core.compression. If that is
not set, defaults to -1, the zlib default, which is "a default
compromise between speed and compression (currently equivalent
to level 6)."
+
Note that changing the compression level will not automatically recompress
all existing objects. You can force recompression by passing the -F option
to linkgit:git-repack[1].
pack.allowPackReuse::
When true or "single", and when reachability bitmaps are
enabled, pack-objects will try to send parts of the bitmapped
packfile verbatim. When "multi", and when a multi-pack
reachability bitmap is available, pack-objects will try to send
parts of all packs in the MIDX.
+
If only a single pack bitmap is available, and `pack.allowPackReuse`
is set to "multi", reuse parts of just the bitmapped packfile. This
can reduce memory and CPU usage to serve fetches, but might result in
sending a slightly larger pack. Defaults to true.
pack.island::
An extended regular expression configuring a set of delta
islands. See "DELTA ISLANDS" in linkgit:git-pack-objects[1]
for details.
pack.islandCore::
Specify an island name which gets to have its objects be
packed first. This creates a kind of pseudo-pack at the front
of one pack, so that the objects from the specified island are
hopefully faster to copy into any pack that should be served
to a user requesting these objects. In practice this means
that the island specified should likely correspond to what is
the most commonly cloned in the repo. See also "DELTA ISLANDS"
in linkgit:git-pack-objects[1].
pack.deltaCacheSize::
The maximum memory in bytes used for caching deltas in
linkgit:git-pack-objects[1] before writing them out to a pack.
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. Repacking large repositories on machines
which are tight with memory might be badly impacted by this though,
especially if this cache pushes the system into swapping.
A value of 0 means no limit. The smallest size of 1 byte may be
used to virtually disable this cache. Defaults to 256 MiB.
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
