and might match multiple refs in the .git/refs/ tree. True by default.
core.compression::
+ An integer -1..9, indicating a default compression level.
+ -1 is the zlib default. 0 means no compression,
+ and 1..9 are various speed/size tradeoffs, 9 being slowest.
+
+ core.loosecompression::
An integer -1..9, indicating the compression level for objects that
- are not in a pack file. -1 is the zlib and git default. 0 means no
+ are not in a pack file. -1 is the zlib default. 0 means no
compression, and 1..9 are various speed/size tradeoffs, 9 being
- slowest.
+ slowest. If not set, defaults to core.compression. If that is
+ not set, defaults to 0 (best speed).
-core.legacyheaders::
- A boolean which
- changes the format of loose objects so that they are more
- efficient to pack and to send out of the repository over git
- native protocol, since v1.4.2. However, loose objects
- written in the new format cannot be read by git older than
- that version; people fetching from your repository using
- older versions of git over dumb transports (e.g. http)
- will also be affected.
-+
-To let git use the new loose object format, you have to
-set core.legacyheaders to false.
-
core.packedGitWindowSize::
Number of bytes of a pack file to map into memory in a
single mapping operation. Larger window sizes may allow
`.patch`. Use this variable to change that suffix (make sure to
include the dot if you want it).
+gc.aggressiveWindow::
+ The window size parameter used in the delta compression
+ algorithm used by 'git gc --aggressive'. This defaults
+ to 10.
+
gc.packrefs::
`git gc` does not run `git pack-refs` in a bare repository by
default so that older dumb-transport clients can still fetch
The maximum delta depth used by gitlink:git-pack-objects[1] when no
maximum depth is given on the command line. Defaults to 50.
+ 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.
+
pull.octopus::
The default merge strategy to use when pulling multiple branches
at once.
