<h2>NAME</h2> | |
<div class="sectionbody"> | |
<p>git-bundle - | |
Move objects and refs by archive | |
</p> | |
</div> | |
</div> | |
<h2>SYNOPSIS</h2> | |
<div class="sectionbody"> | |
<div class="verseblock"> | |
<div class="content"><em>git-bundle</em> create <file> [git-rev-list args] | |
<em>git-bundle</em> verify <file> | |
<em>git-bundle</em> list-heads <file> [refname…] | |
<em>git-bundle</em> unbundle <file> [refname…]</div></div> | |
</div> | |
<h2>DESCRIPTION</h2> | |
<div class="sectionbody"> | |
<p>Some workflows require that one or more branches of development on one | |
machine be replicated on another machine, but the two machines cannot | |
be directly connected so the interactive git protocols (git, ssh, | |
rsync, http) cannot be used. This command provides support for | |
git-fetch and git-pull to operate by packaging objects and references | |
in an archive at the originating machine, then importing those into | |
another repository using <a href="git-fetch.html">git-fetch(1)</a> and <a href="git-pull.html">git-pull(1)</a> | |
after moving the archive by some means (i.e., by sneakernet). As no | |
direct connection between repositories exists, the user must specify a | |
basis for the bundle that is held by the destination repository: the | |
bundle assumes that all objects in the basis are already in the | |
destination repository.</p> | |
</div> | |
<h2>OPTIONS</h2> | |
<div class="sectionbody"> | |
<dl> | |
<dt> | |
create <file> | |
</dt> | |
<dd> | |
<p> | |
Used to create a bundle named <em>file</em>. This requires the | |
git-rev-list arguments to define the bundle contents. | |
</p> | |
</dd> | |
<dt> | |
verify <file> | |
</dt> | |
<dd> | |
<p> | |
Used to check that a bundle file is valid and will apply | |
cleanly to the current repository. This includes checks on the | |
bundle format itself as well as checking that the prerequisite | |
commits exist and are fully linked in the current repository. | |
git-bundle prints a list of missing commits, if any, and exits | |
with non-zero status. | |
</p> | |
</dd> | |
<dt> | |
list-heads <file> | |
</dt> | |
<dd> | |
<p> | |
Lists the references defined in the bundle. If followed by a | |
list of references, only references matching those given are | |
printed out. | |
</p> | |
</dd> | |
<dt> | |
unbundle <file> | |
</dt> | |
<dd> | |
<p> | |
Passes the objects in the bundle to <a href="git-index-pack.html">git-index-pack(1)</a> | |
for storage in the repository, then prints the names of all | |
defined references. If a reflist is given, only references | |
matching those in the given list are printed. This command is | |
really plumbing, intended to be called only by | |
<a href="git-fetch.html">git-fetch(1)</a>. | |
</p> | |
</dd> | |
<dt> | |
[git-rev-list-args…] | |
</dt> | |
<dd> | |
<p> | |
A list of arguments, acceptable to git-rev-parse and | |
git-rev-list, that specify the specific objects and references | |
to transport. For example, "master~10..master" causes the | |
current master reference to be packaged along with all objects | |
added since its 10th ancestor commit. There is no explicit | |
limit to the number of references and objects that may be | |
packaged. | |
</p> | |
</dd> | |
<dt> | |
[refname…] | |
</dt> | |
<dd> | |
<p> | |
A list of references used to limit the references reported as | |
available. This is principally of use to git-fetch, which | |
expects to receive only those references asked for and not | |
necessarily everything in the pack (in this case, git-bundle is | |
acting like <a href="git-fetch-pack.html">git-fetch-pack(1)</a>). | |
</p> | |
</dd> | |
</dl> | |
</div> | |
<h2>SPECIFYING REFERENCES</h2> | |
<div class="sectionbody"> | |
<p>git-bundle will only package references that are shown by | |
git-show-ref: this includes heads, tags, and remote heads. References | |
such as master~1 cannot be packaged, but are perfectly suitable for | |
defining the basis. More than one reference may be packaged, and more | |
than one basis can be specified. The objects packaged are those not | |
contained in the union of the given bases. Each basis can be | |
specified explicitly (e.g., ^master~10), or implicitly (e.g., | |
master~10..master, master --since=10.days.ago).</p> | |
<p>It is very important that the basis used be held by the destination. | |
It is okay to err on the side of conservatism, causing the bundle file | |
to contain objects already in the destination as these are ignored | |
when unpacking at the destination.</p> | |
</div> | |
<h2>EXAMPLE</h2> | |
<div class="sectionbody"> | |
<p>Assume two repositories exist as R1 on machine A, and R2 on machine B. | |
For whatever reason, direct connection between A and B is not allowed, | |
but we can move data from A to B via some mechanism (CD, email, etc). | |
We want to update R2 with developments made on branch master in R1.</p> | |
<p>To create the bundle you have to specify the basis. You have some options:</p> | |
<ul> | |
<li> | |
<p> | |
Without basis. | |
</p> | |
<p>This is useful when sending the whole history.</p> | |
</li> | |
</ul> | |
<div class="listingblock"> | |
<div class="content"> | |
<pre><tt>$ git bundle create mybundle master</tt></pre> | |
</div></div> | |
<ul> | |
<li> | |
<p> | |
Using temporally tags. | |
</p> | |
<p>We set a tag in R1 (lastR2bundle) after the previous such transport, | |
and move it afterwards to help build the bundle.</p> | |
</li> | |
</ul> | |
<div class="listingblock"> | |
<div class="content"> | |
<pre><tt>$ git-bundle create mybundle master ^lastR2bundle | |
$ git tag -f lastR2bundle master</tt></pre> | |
</div></div> | |
<ul> | |
<li> | |
<p> | |
Using a tag present in both repositories | |
</p> | |
</li> | |
</ul> | |
<div class="listingblock"> | |
<div class="content"> | |
<pre><tt>$ git bundle create mybundle master ^v1.0.0</tt></pre> | |
</div></div> | |
<ul> | |
<li> | |
<p> | |
A basis based on time. | |
</p> | |
</li> | |
</ul> | |
<div class="listingblock"> | |
<div class="content"> | |
<pre><tt>$ git bundle create mybundle master --since=10.days.ago</tt></pre> | |
</div></div> | |
<ul> | |
<li> | |
<p> | |
With a limit on the number of commits | |
</p> | |
</li> | |
</ul> | |
<div class="listingblock"> | |
<div class="content"> | |
<pre><tt>$ git bundle create mybundle master -n 10</tt></pre> | |
</div></div> | |
<p>Then you move mybundle from A to B, and in R2 on B:</p> | |
<div class="listingblock"> | |
<div class="content"> | |
<pre><tt>$ git-bundle verify mybundle | |
$ git-fetch mybundle master:localRef</tt></pre> | |
</div></div> | |
<p>With something like this in the config in R2:</p> | |
<div class="listingblock"> | |
<div class="content"> | |
<pre><tt>[remote "bundle"] | |
url = /home/me/tmp/file.bdl | |
fetch = refs/heads/*:refs/remotes/origin/*</tt></pre> | |
</div></div> | |
<p>You can first sneakernet the bundle file to ~/tmp/file.bdl and | |
then these commands on machine B:</p> | |
<div class="listingblock"> | |
<div class="content"> | |
<pre><tt>$ git ls-remote bundle | |
$ git fetch bundle | |
$ git pull bundle</tt></pre> | |
</div></div> | |
<p>would treat it as if it is talking with a remote side over the | |
network.</p> | |
