6 git-bundle - Move objects and refs by archive
12 'git bundle' create <file> [--basis=ref] <git-rev-list args>
13 'git bundle' verify <file>
14 'git bundle' list-heads <file> [refname...]
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 'git-fetch' and 'git-pull'
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 'git-index-pack'
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 'git-fetch'.
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
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 'git-fetch-pack').
78 Specify a basis ref that already exists on the remote side. This
79 allows git-bundle to only write out objects that are newer, thus
85 'git-bundle' will only package references that are shown by
86 'git-show-ref': this includes heads, tags, and remote heads. References
87 such as master~1 cannot be packaged, but are perfectly suitable for
88 defining the basis. More than one reference may be packaged, and more
89 than one basis can be specified. The objects packaged are those not
90 contained in the union of the given bases. Each basis can be
91 specified explicitly (e.g., ^master~10), or implicitly (e.g.,
92 master~10..master, master --since=10.days.ago).
94 It is very important that the basis used be held by the destination.
95 It is okay to err on the side of conservatism, causing the bundle file
96 to contain objects already in the destination as these are ignored
97 when unpacking at the destination.
102 Assume two repositories exist as R1 on machine A, and R2 on machine B.
103 For whatever reason, direct connection between A and B is not allowed,
104 but we can move data from A to B via some mechanism (CD, email, etc).
105 We want to update R2 with developments made on branch master in R1.
107 To create the bundle you have to specify the basis. You have some options:
111 This is useful when sending the whole history.
114 $ git bundle create mybundle master
117 - Using temporally tags.
119 We set a tag in R1 (lastR2bundle) after the previous such transport,
120 and move it afterwards to help build the bundle.
123 $ git bundle create mybundle --basis=lastR2bundle master
124 $ git tag -f lastR2bundle master
127 - Using a tag present in both repositories
130 $ git bundle create mybundle --basis=v1.0.0 master
133 - A basis based on time.
136 $ git bundle create mybundle master --since=10.days.ago
139 - With a limit on the number of commits
142 $ git bundle create mybundle master -n 10
145 Then you move mybundle from A to B, and in R2 on B:
148 $ git bundle verify mybundle
149 $ git fetch mybundle master:localRef
152 With something like this in the config in R2:
154 ------------------------
156 url = /home/me/tmp/file.bdl
157 fetch = refs/heads/*:refs/remotes/origin/*
158 ------------------------
160 You can first sneakernet the bundle file to ~/tmp/file.bdl and
161 then these commands on machine B:
164 $ git ls-remote bundle
169 would treat it as if it is talking with a remote side over the
