15 'git-bundle' unbundle <file> [refname...]
20 Some workflows require that one or more branches of development on one
21 machine be replicated on another machine, but the two machines cannot
22 be directly connected so the interactive git protocols (git, ssh,
23 rsync, http) cannot be used. This command provides support for
24 git-fetch and git-pull to operate by packaging objects and references
25 in an archive at the originating machine, then importing those into
26 another repository using linkgit:git-fetch[1] and linkgit:git-pull[1]
27 after moving the archive by some means (i.e., by sneakernet). As no
28 direct connection between repositories exists, the user must specify a
29 basis for the bundle that is held by the destination repository: the
30 bundle assumes that all objects in the basis are already in the
31 destination repository.
37 Used to create a bundle named 'file'. This requires the
38 git-rev-list arguments to define the bundle contents.
41 Used to check that a bundle file is valid and will apply
42 cleanly to the current repository. This includes checks on the
43 bundle format itself as well as checking that the prerequisite
44 commits exist and are fully linked in the current repository.
45 git-bundle prints a list of missing commits, if any, and exits
49 Lists the references defined in the bundle. If followed by a
50 list of references, only references matching those given are
54 Passes the objects in the bundle to linkgit:git-index-pack[1]
55 for storage in the repository, then prints the names of all
56 defined references. If a reflist is given, only references
57 matching those in the given list are printed. This command is
58 really plumbing, intended to be called only by
61 [git-rev-list-args...]::
62 A list of arguments, acceptable to git-rev-parse and
63 git-rev-list, that specify the specific objects and references
64 to transport. For example, "master~10..master" causes the
65 current master reference to be packaged along with all objects
66 added since its 10th ancestor commit. There is no explicit
67 limit to the number of references and objects that may be
72 A list of references used to limit the references reported as
73 available. This is principally of use to git-fetch, which
74 expects to receive only those references asked for and not
75 necessarily everything in the pack (in this case, git-bundle is
76 acting like linkgit:git-fetch-pack[1]).
81 git-bundle will only package references that are shown by
82 git-show-ref: this includes heads, tags, and remote heads. References
83 such as master~1 cannot be packaged, but are perfectly suitable for
84 defining the basis. More than one reference may be packaged, and more
85 than one basis can be specified. The objects packaged are those not
86 contained in the union of the given bases. Each basis can be
87 specified explicitly (e.g., ^master~10), or implicitly (e.g.,
88 master~10..master, master --since=10.days.ago).
90 It is very important that the basis used be held by the destination.
91 It is okay to err on the side of conservatism, causing the bundle file
92 to contain objects already in the destination as these are ignored
93 when unpacking at the destination.
98 Assume two repositories exist as R1 on machine A, and R2 on machine B.
99 For whatever reason, direct connection between A and B is not allowed,
100 but we can move data from A to B via some mechanism (CD, email, etc).
101 We want to update R2 with developments made on branch master in R1.
103 To create the bundle you have to specify the basis. You have some options:
107 This is useful when sending the whole history.
110 $ git bundle create mybundle master
113 - Using temporally tags.
115 We set a tag in R1 (lastR2bundle) after the previous such transport,
116 and move it afterwards to help build the bundle.
119 $ git-bundle create mybundle master ^lastR2bundle
120 $ git tag -f lastR2bundle master
123 - Using a tag present in both repositories
126 $ git bundle create mybundle master ^v1.0.0
129 - A basis based on time.
132 $ git bundle create mybundle master --since=10.days.ago
135 - With a limit on the number of commits
138 $ git bundle create mybundle master -n 10
141 Then you move mybundle from A to B, and in R2 on B:
144 $ git-bundle verify mybundle
145 $ git-fetch mybundle master:localRef
148 With something like this in the config in R2:
150 ------------------------
152 url = /home/me/tmp/file.bdl
153 fetch = refs/heads/*:refs/remotes/origin/*
154 ------------------------
156 You can first sneakernet the bundle file to ~/tmp/file.bdl and
157 then these commands on machine B:
160 $ git ls-remote bundle
165 would treat it as if it is talking with a remote side over the
