+ 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.
+ 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.
+ 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.
+ 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].
+ An extended regular expression configuring a set of delta
+ islands. See "DELTA ISLANDS" in linkgit:git-pack-objects[1]
+ for details.
+ 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].
+ 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.
+ 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.
+ 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 CPU's
+ and set the number of threads accordingly.
+ 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 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.
+ 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; which in turn prevents
+ bitmaps from being created.
+ The minimum size allowed is limited to 1 MiB.
+ The default is unlimited.
+ Common unit suffixes of 'k', 'm', or 'g' are
+ supported.
+ 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.writeBitmaps (deprecated)::
+ This is a deprecated synonym for `repack.writeBitmaps`.
+ When true, git will include a "hash cache" section in the bitmap
+ index (if one is written). This cache can be used to feed git's
+ delta heuristics, potentially leading to better deltas between
+ bitmapped and non-bitmapped objects (e.g., when serving a fetch
+ between an older, bitmapped pack and objects that have been
+ pushed since the last gc). The downside is that it consumes 4
+ bytes per object of disk space, and that JGit's bitmap
+ implementation does not understand it, causing it to complain if
+ Git and JGit are used on the same repository. Defaults to false.
