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 When 'git gc' is run, it will call 'prune --expire 2.weeks.ago'.
86 Override the grace period with this config variable. The value
87 "now" may be used to disable this grace period and always prune
88 unreachable objects immediately, or "never" may be used to
89 suppress pruning. This feature helps prevent corruption when
90 'git gc' runs concurrently with another process writing to the
91 repository; see the "NOTES" section of linkgit:git-gc[1].
93 gc.worktreePruneExpire::
94 When 'git gc' is run, it calls
95 'git worktree prune --expire 3.months.ago'.
96 This config variable can be used to set a different grace
97 period. The value "now" may be used to disable the grace
98 period and prune `$GIT_DIR/worktrees` immediately, or "never"
99 may be used to suppress pruning.
102 gc.<pattern>.reflogExpire::
103 'git reflog expire' removes reflog entries older than
104 this time; defaults to 90 days. The value "now" expires all
105 entries immediately, and "never" suppresses expiration
106 altogether. With "<pattern>" (e.g.
107 "refs/stash") in the middle the setting applies only to
108 the refs that match the <pattern>.
110 gc.reflogExpireUnreachable::
111 gc.<pattern>.reflogExpireUnreachable::
112 'git reflog expire' removes reflog entries older than
113 this time and are not reachable from the current tip;
114 defaults to 30 days. The value "now" expires all entries
115 immediately, and "never" suppresses expiration altogether.
116 With "<pattern>" (e.g. "refs/stash")
117 in the middle, the setting applies only to the refs that
120 These types of entries are generally created as a result of using `git
121 commit --amend` or `git rebase` and are the commits prior to the amend
122 or rebase occurring. Since these changes are not part of the current
123 project most users will want to expire them sooner, which is why the
124 default is more aggressive than `gc.reflogExpire`.
127 Records of conflicted merge you resolved earlier are
128 kept for this many days when 'git rerere gc' is run.
129 You can also use more human-readable "1.month.ago", etc.
130 The default is 60 days. See linkgit:git-rerere[1].
132 gc.rerereUnresolved::
133 Records of conflicted merge you have not resolved are
134 kept for this many days when 'git rerere gc' is run.
135 You can also use more human-readable "1.month.ago", etc.
136 The default is 15 days. See linkgit:git-rerere[1].
