2 The depth parameter used in the delta compression
3 algorithm used by 'git gc --aggressive'. This defaults
4 to 50, which is the default for the `--depth` option when
5 `--aggressive` isn't in use.
7 See the documentation for the `--depth` option in
8 linkgit:git-repack[1] for more details.
11 The window size parameter used in the delta compression
12 algorithm used by 'git gc --aggressive'. This defaults
13 to 250, which is a much more aggressive window size than
14 the default `--window` of 10.
16 See the documentation for the `--window` option in
17 linkgit:git-repack[1] for more details.
20 When there are approximately more than this many loose
21 objects in the repository, `git gc --auto` will pack them.
22 Some Porcelain commands use this command to perform a
23 light-weight garbage collection from time to time. The
24 default value is 6700.
26 Setting this to 0 disables not only automatic packing based on the
27 number of loose objects, but any other heuristic `git gc --auto` will
28 otherwise use to determine if there's work to do, such as
32 When there are more than this many packs that are not
33 marked with `*.keep` file in the repository, `git gc
34 --auto` consolidates them into one larger pack. The
35 default value is 50. Setting this to 0 disables it.
36 Setting `gc.auto` to 0 will also disable this.
38 See the `gc.bigPackThreshold` configuration variable below. When in
39 use, it'll affect how the auto pack limit works.
42 Make `git gc --auto` return immediately and run in background
43 if the system supports it. Default is true.
46 If non-zero, all packs larger than this limit are kept when
47 `git gc` is run. This is very similar to `--keep-largest-pack`
48 except that all packs that meet the threshold are kept, not
49 just the largest pack. Defaults to zero. Common unit suffixes of
50 'k', 'm', or 'g' are supported.
52 Note that if the number of kept packs is more than gc.autoPackLimit,
53 this configuration variable is ignored, all packs except the base pack
54 will be repacked. After this the number of packs should go below
55 gc.autoPackLimit and gc.bigPackThreshold should be respected again.
57 If the amount of memory estimated for `git repack` to run smoothly is
58 not available and `gc.bigPackThreshold` is not set, the largest pack
59 will also be excluded (this is the equivalent of running `git gc` with
60 `--keep-largest-pack`).
63 If true, then gc will rewrite the commit-graph file when
64 linkgit:git-gc[1] is run. When using `git gc --auto`
65 the commit-graph will be updated if housekeeping is
66 required. Default is true. See linkgit:git-commit-graph[1]
70 If the file gc.log exists, then `git gc --auto` will print
71 its content and exit with status zero instead of running
72 unless that file is more than 'gc.logExpiry' old. Default is
73 "1.day". See `gc.pruneExpire` for more ways to specify its
77 Running `git pack-refs` in a repository renders it
78 unclonable by Git versions prior to 1.5.1.2 over dumb
79 transports such as HTTP. This variable determines whether
80 'git gc' runs `git pack-refs`. This can be set to `notbare`
81 to enable it within all non-bare repos or it can be set to a
82 boolean value. The default is `true`.
85 Store unreachable objects in a cruft pack (see
86 linkgit:git-repack[1]) instead of as loose objects. The default
90 When 'git gc' is run, it will call 'prune --expire 2.weeks.ago'
91 (and 'repack --cruft --cruft-expiration 2.weeks.ago' if using
92 cruft packs via `gc.cruftPacks` or `--cruft`). Override the
93 grace period with this config variable. The value "now" may be
94 used to disable this grace period and always prune unreachable
95 objects immediately, or "never" may be used to suppress pruning.
96 This feature helps prevent corruption when 'git gc' runs
97 concurrently with another process writing to the repository; see
98 the "NOTES" section of linkgit:git-gc[1].
100 gc.worktreePruneExpire::
101 When 'git gc' is run, it calls
102 'git worktree prune --expire 3.months.ago'.
103 This config variable can be used to set a different grace
104 period. The value "now" may be used to disable the grace
105 period and prune `$GIT_DIR/worktrees` immediately, or "never"
106 may be used to suppress pruning.
109 gc.<pattern>.reflogExpire::
110 'git reflog expire' removes reflog entries older than
111 this time; defaults to 90 days. The value "now" expires all
112 entries immediately, and "never" suppresses expiration
113 altogether. With "<pattern>" (e.g.
114 "refs/stash") in the middle the setting applies only to
115 the refs that match the <pattern>.
117 gc.reflogExpireUnreachable::
118 gc.<pattern>.reflogExpireUnreachable::
119 'git reflog expire' removes reflog entries older than
120 this time and are not reachable from the current tip;
121 defaults to 30 days. The value "now" expires all entries
122 immediately, and "never" suppresses expiration altogether.
123 With "<pattern>" (e.g. "refs/stash")
124 in the middle, the setting applies only to the refs that
127 These types of entries are generally created as a result of using `git
128 commit --amend` or `git rebase` and are the commits prior to the amend
129 or rebase occurring. Since these changes are not part of the current
130 project most users will want to expire them sooner, which is why the
131 default is more aggressive than `gc.reflogExpire`.
134 Records of conflicted merge you resolved earlier are
135 kept for this many days when 'git rerere gc' is run.
136 You can also use more human-readable "1.month.ago", etc.
137 The default is 60 days. See linkgit:git-rerere[1].
139 gc.rerereUnresolved::
140 Records of conflicted merge you have not resolved are
141 kept for this many days when 'git rerere gc' is run.
142 You can also use more human-readable "1.month.ago", etc.
143 The default is 15 days. See linkgit:git-rerere[1].
