6 git-bundle - Move objects and refs by archive
9 SYNOPSIS
10 --------
11 'git-bundle' create <file> [git-rev-list args]
12 'git-bundle' verify <file>
13 'git-bundle' list-heads <file> [refname...]
14 'git-bundle' unbundle <file> [refname...]
16 DESCRIPTION
17 -----------
19 Some workflows require that one or more branches of development on one
20 machine be replicated on another machine, but the two machines cannot
21 be directly connected so the interactive git protocols (git, ssh,
22 rsync, http) cannot be used. This command provides support for
23 git-fetch and git-pull to operate by packaging objects and references
24 in an archive at the originating machine, then importing those into
25 another repository using gitlink:git-fetch[1] and gitlink:git-pull[1]
26 after moving the archive by some means (i.e., by sneakernet). As no
27 direct connection between repositories exists, the user must specify a
28 basis for the bundle that is held by the destination repository: the
29 bundle assumes that all objects in the basis are already in the
30 destination repository.
32 OPTIONS
33 -------
35 create <file>::
36 Used to create a bundle named 'file'. This requires the
37 git-rev-list arguments to define the bundle contents.
39 verify <file>::
40 Used to check that a bundle file is valid and will apply
41 cleanly to the current repository. This includes checks on the
42 bundle format itself as well as checking that the prerequisite
43 commits exist and are fully linked in the current repository.
44 git-bundle prints a list of missing commits, if any, and exits
45 with non-zero status.
47 list-heads <file>::
48 Lists the references defined in the bundle. If followed by a
49 list of references, only references matching those given are
50 printed out.
52 unbundle <file>::
53 Passes the objects in the bundle to gitlink:git-index-pack[1]
54 for storage in the repository, then prints the names of all
55 defined references. If a reflist is given, only references
56 matching those in the given list are printed. This command is
57 really plumbing, intended to be called only by
58 gitlink:git-fetch[1].
60 [git-rev-list-args...]::
61 A list of arguments, acceptable to git-rev-parse and
62 git-rev-list, that specify the specific objects and references
63 to transport. For example, "master~10..master" causes the
64 current master reference to be packaged along with all objects
65 added since its 10th ancestor commit. There is no explicit
66 limit to the number of references and objects that may be
67 packaged.
70 [refname...]::
71 A list of references used to limit the references reported as
72 available. This is principally of use to git-fetch, which
73 expects to receive only those references asked for and not
74 necessarily everything in the pack (in this case, git-bundle is
75 acting like gitlink:git-fetch-pack[1]).
77 SPECIFYING REFERENCES
78 ---------------------
80 git-bundle will only package references that are shown by
81 git-show-ref: this includes heads, tags, and remote heads. References
82 such as master~1 cannot be packaged, but are perfectly suitable for
83 defining the basis. More than one reference may be packaged, and more
84 than one basis can be specified. The objects packaged are those not
85 contained in the union of the given bases. Each basis can be
86 specified explicitly (e.g., ^master~10), or implicitly (e.g.,
87 master~10..master, master --since=10.days.ago).
89 It is very important that the basis used be held by the destination.
90 It is okay to err on the side of conservatism, causing the bundle file
91 to contain objects already in the destination as these are ignored
92 when unpacking at the destination.
94 EXAMPLE
95 -------
97 Assume two repositories exist as R1 on machine A, and R2 on machine B.
98 For whatever reason, direct connection between A and B is not allowed,
99 but we can move data from A to B via some mechanism (CD, email, etc).
100 We want to update R2 with developments made on branch master in R1.
101 We set a tag in R1 (lastR2bundle) after the previous such transport,
102 and move it afterwards to help build the bundle.
104 in R1 on A:
105 $ git-bundle create mybundle master ^lastR2bundle
106 $ git tag -f lastR2bundle master
108 (move mybundle from A to B by some mechanism)
110 in R2 on B:
111 $ git-bundle verify mybundle
112 $ git-fetch mybundle refspec
114 where refspec is refInBundle:localRef
117 Also, with something like this in your config:
119 [remote "bundle"]
120 url = /home/me/tmp/file.bdl
121 fetch = refs/heads/*:refs/remotes/origin/*
123 You can first sneakernet the bundle file to ~/tmp/file.bdl and
124 then these commands:
126 $ git ls-remote bundle
127 $ git fetch bundle
128 $ git pull bundle
130 would treat it as if it is talking with a remote side over the
131 network.
