| 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.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 CPU's |
| 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 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; 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. |
| |
| 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.writeBitmaps (deprecated):: |
| This is a deprecated synonym for `repack.writeBitmaps`. |
| |
| pack.writeBitmapHashCache:: |
| 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. |
