|
|
<p>Jujutsu has two backends for storing commits. One of them uses a regular Git
|
|
repo, which means that you can collaborate with Git users without them even
|
|
knowing that you're not using the <code>git</code> CLI.</p>
|
|
<p>See <code>jj help git</code> for help about the <code>jj git</code> family of commands, and e.g.
|
|
<code>jj help git push</code> for help about a specific command (use <code>jj git push -h</code> for
|
|
briefer help).</p>
|
|
<h2 id="supported-features">Supported features<a class="headerlink" href="#supported-features" title="Permanent link">¶</a></h2>
|
|
<p>The following list describes which Git features Jujutsu is compatible with. For
|
|
a comparison with Git, including how workflows are different, see the
|
|
<a href="../git-comparison/">Git-comparison doc</a>.</p>
|
|
<ul>
|
|
<li><strong>Configuration: Partial.</strong> The only configuration from Git (e.g. in
|
|
<code>~/.gitconfig</code>) that's respected is the following. Feel free to file a bug if
|
|
you miss any particular configuration options.<ul>
|
|
<li>The configuration of remotes (<code>[remote "<name>"]</code>).</li>
|
|
<li><code>core.excludesFile</code></li>
|
|
</ul>
|
|
</li>
|
|
<li><strong>Authentication: Partial.</strong> Only <code>ssh-agent</code>, a password-less key (
|
|
only <code>~/.ssh/id_rsa</code>, <code>~/.ssh/id_ed25519</code> or <code>~/.ssh/id_ed25519_sk</code>), or
|
|
a <code>credential.helper</code>.</li>
|
|
<li><strong>Branches: Yes.</strong> You can read more about
|
|
<a href="../bookmarks/">how branches work in Jujutsu</a>
|
|
and <a href="#branches">how they interoperate with Git</a>.</li>
|
|
<li><strong>Tags: Partial.</strong> You can check out tagged commits by name (pointed to be
|
|
either annotated or lightweight tags), but you cannot create new tags.</li>
|
|
<li><strong>.gitignore: Yes.</strong> Ignores in <code>.gitignore</code> files are supported. So are
|
|
ignores in <code>.git/info/exclude</code> or configured via Git's <code>core.excludesfile</code>
|
|
config. The <code>.gitignore</code> support uses a native implementation, so please
|
|
report a bug if you notice any difference compared to <code>git</code>.</li>
|
|
<li><strong>.gitattributes: No.</strong> There's <a href="https://github.com/martinvonz/jj/issues/53">#53</a>
|
|
about adding support for at least the <code>eol</code> attribute.</li>
|
|
<li><strong>Hooks: No.</strong> There's <a href="https://github.com/martinvonz/jj/issues/405">#405</a>
|
|
specifically for providing the checks from https://pre-commit.com.</li>
|
|
<li><strong>Merge commits: Yes.</strong> Octopus merges (i.e. with more than 2 parents) are
|
|
also supported.</li>
|
|
<li><strong>Detached HEAD: Yes.</strong> Jujutsu supports anonymous branches, so this is a
|
|
natural state.</li>
|
|
<li><strong>Orphan branch: Yes.</strong> Jujutsu has a virtual root commit that appears as
|
|
parent of all commits Git would call "root commits".</li>
|
|
<li><strong>Staging area: Kind of.</strong> The staging area will be ignored. For example,
|
|
<code>jj diff</code> will show a diff from the Git HEAD to the working copy. There are
|
|
<a href="https://github.com/martinvonz/jj/blob/main/docs/git-comparison.md#the-index">ways of fulfilling your use cases without a staging
|
|
area</a>.</li>
|
|
<li><strong>Garbage collection: Yes.</strong> It should be safe to run <code>git gc</code> in the Git
|
|
repo, but it's not tested, so it's probably a good idea to make a backup of
|
|
the whole workspace first. There's <a href="https://github.com/martinvonz/jj/issues/12">no garbage collection and repacking of
|
|
Jujutsu's own data structures yet</a>,
|
|
however.</li>
|
|
<li><strong>Bare repositories: Yes.</strong> You can use <code>jj git init --git-repo=<path></code> to
|
|
create a repo backed by a bare Git repo.</li>
|
|
<li><strong>Submodules: No.</strong> They will not show up in the working copy, but they will
|
|
not be lost either.</li>
|
|
<li><strong>Partial clones: No.</strong> We use the <a href="https://libgit2.org/">libgit2</a> library,
|
|
which <a href="https://github.com/libgit2/libgit2/issues/5564">doesn't have support for partial clones</a>.</li>
|
|
<li><strong>Shallow clones: No.</strong> We use the <a href="https://libgit2.org/">libgit2</a> library,
|
|
which <a href="https://github.com/libgit2/libgit2/issues/3058">doesn't have support for shallow clones</a>.</li>
|
|
<li><strong>git-worktree: No.</strong> However, there's native support for multiple working
|
|
copies backed by a single repo. See the <code>jj workspace</code> family of commands.</li>
|
|
<li><strong>Sparse checkouts: No.</strong> However, there's native support for sparse
|
|
checkouts. See the <code>jj sparse</code> command.</li>
|
|
<li><strong>Signed commits: Partial.</strong>
|
|
So far only <a href="https://github.com/martinvonz/jj/blob/main/docs/config.md#commit-signing">by configuration</a>,
|
|
later perhaps <a href="https://github.com/martinvonz/jj/pull/3142">a command</a>.</li>
|
|
<li><strong>Git LFS: No.</strong> (<a href="https://github.com/martinvonz/jj/issues/80">#80</a>)</li>

<h2 id="creating-an-empty-repo">Creating an empty repo<a class="headerlink" href="#creating-an-empty-repo" title="Permanent link">¶</a></h2>
|
|
<p>To create an empty repo using the Git backend, use <code>jj init --git <name></code>. Since
|
|
the command creates a Jujutsu repo, it will have a <code>.jj/</code> directory. The
|
|
underlying Git repo will be inside of that directory (currently in
|
|
<code>.jj/repo/store/git/</code>).</p>
|
|
<h2 id="creating-a-repo-backed-by-an-existing-git-repo">Creating a repo backed by an existing Git repo<a class="headerlink" href="#creating-a-repo-backed-by-an-existing-git-repo" title="Permanent link">¶</a></h2>
|
|
<p>To create a Jujutsu repo backed by a Git repo you already have on disk, use
|
|
<code>jj git init --git-repo=<path to Git repo> <name></code>. The repo will work similar
|
|
to a <a href="https://git-scm.com/docs/git-worktree">Git worktree</a>, meaning that the
|
|
working copies files and the record of the working-copy commit will be separate,
|
|
but the commits will be accessible in both repos. Use <code>jj git import</code> to update
|
|
the Jujutsu repo with changes made in the Git repo. Use <code>jj git export</code> to
|
|
update the Git repo with changes made in the Jujutsu repo.</p>
|
|
<h2 id="creating-a-repo-by-cloning-a-git-repo">Creating a repo by cloning a Git repo<a class="headerlink" href="#creating-a-repo-by-cloning-a-git-repo" title="Permanent link">¶</a></h2>
|
|
<p>To create a Jujutsu repo from a remote Git URL, use <code>jj git clone <URL>
|
|
[<destination>]</code>. For example, <code>jj git clone
|
|
https://github.com/octocat/Hello-World</code> will clone GitHub's "Hello-World" repo
|
|
into a directory by the same name.</p>
|
|
<p>By default, the remote repository will be named <code>origin</code>. You can use
|
|
a name of your choice by adding <code>--remote <remote name></code> to the <code>jj
|
|
git clone</code> command.</p>
|
|
<h2 id="co-located-jujutsugit-repos">Co-located Jujutsu/Git repos<a class="headerlink" href="#co-located-jujutsugit-repos" title="Permanent link">¶</a></h2>
|
|
<p>A "co-located" Jujutsu repo is a hybrid Jujutsu/Git repo. These can be created
|
|
if you initialize the Jujutsu repo in an existing Git repo by running <code>jj git
|
|
init --colocate</code> or with <code>jj git clone --colocate</code>. The Git repo and the Jujutsu
|
|
repo then share the same working copy. Jujutsu will import and export from and
|
|
to the Git repo on every <code>jj</code> command automatically.</p>
|
|
<p>This mode is very convenient when tools (e.g. build tools) expect a Git repo to
|
|
be present.</p>
|
|
<p>It is allowed to mix <code>jj</code> and <code>git</code> commands in such a repo in any order.
|
|
However, it may be easier to keep track of what is going on if you mostly use
|
|
read-only <code>git</code> commands and use <code>jj</code> to make changes to the repo. One reason
|
|
for this (see below for more) is that <code>jj</code> commands will usually put the git
|
|
repo in a "detached HEAD" state, since in <code>jj</code> there is not concept of a
|
|
"currently tracked branch". Before doing mutating Git commands, you may need to
|
|
tell Git what the current branch should be with a <code>git switch</code> command.</p>
|
|
<p>You can undo the results of mutating <code>git</code> commands using <code>jj undo</code> and <code>jj op
|
|
restore</code>. Inside <code>jj op log</code>, changes by <code>git</code> will be represented as an "import
|
|
git refs" operation.</p>
|
|
<p>There are a few downsides to this mode of operation. Generally, using co-located
|
|
repos may require you to deal with more involved Jujutsu and Git concepts.</p>
|
|
<ul>
|
|
<li>
|
|
<p>Interleaving <code>jj</code> and <code>git</code> commands increases the chance of confusing branch
|
|
conflicts or <a href="../glossary/#divergent-change">conflicted (AKA divergent) change
|
|
ids</a>. These never lose data, but can be
|
|
annoying.</p>
|
|
<p>Such interleaving can happen unknowingly. For example, some IDEs can cause
|
|
it because they automatically run <code>git fetch</code> in the background from time to
|
|
time.</p>
|
|
</li>
|
|
<li>
|
|
<p>In co-located repos with a very large number of branches or other refs, <code>jj</code>
|
|
commands can get noticeably slower because of the automatic <code>jj git import</code>
|
|
executed on each command. This can be mitigated by occasionally running <code>jj util
|
|
gc</code> to speed up the import (that command includes packing the Git refs).</p>
|
|
</li>
|
|
<li>
|
|
<p>Git tools will have trouble with revisions that contain conflicted files. While
|
|
<code>jj</code> renders these files with conflict markers in the working copy, they are
|
|
stored in a non-human-readable fashion inside the repo. Git tools will often
|
|
see this non-human-readable representation.</p>
|
|
</li>
|
|
<li>
|
|
<p>When a <code>jj</code> branch is conflicted, the position of the branch in the Git repo
|
|
will disagree with one or more of the conflicted positions. The state of that
|
|
branch in git will be labeled as though it belongs to a remote named "git",
|
|
e.g. <code>branch@git</code>.</p>
|
|
</li>
|
|
<li>
|
|
<p>Jujutsu will ignore Git's staging area. It will not understand merge conflicts
|
|
as Git represents them, unfinished <code>git rebase</code> states, as well as other less
|
|
common states a Git repository can be in.</p>
|
|
</li>
|
|
<li>
|
|
<p>Colocated repositories are less resilient to
|
|
<a href="../technical/concurrency/#syncing-with-rsync-nfs-dropbox-etc">concurrency</a>
|
|
issues if you share the repo using an NFS filesystem or Dropbox. In general,
|
|
such use of Jujutsu is not currently thoroughly tested.</p>
|
|
</li>
|
|
<li>
|
|
<p>There may still be bugs when interleaving mutating <code>jj</code> and <code>git</code> commands,
|
|
usually having to do with a branch pointer ending up in the wrong place. We
|
|
are working on the known ones, and are not aware of any major ones. Please
|
|
report any new ones you find, or if any of the known bugs are less minor than
|
|
they appear.</p>

|
|
<p>A Jujutsu repo backed by a Git repo has a full Git repo inside, so it is
|
|
technically possible (though not officially supported) to convert it into a
|
|
co-located repo like so:</p>
|
|
<div class="highlight"><pre><span></span><code><span class="c1"># Move the Git repo</span>
|
|
mv<span class="w"> </span>.jj/repo/store/git<span class="w"> </span>.git

|
|
<span class="nb">echo</span><span class="w"> </span>-n<span class="w"> </span><span class="s1">'../../../.git'</span><span class="w"> </span>><span class="w"> </span>.jj/repo/store/git_target
|
|
<span class="c1"># Ignore the .jj directory in Git</span>
|
|
<span class="nb">echo</span><span class="w"> </span><span class="s1">'/*'</span><span class="w"> </span>><span class="w"> </span>.jj/.gitignore
|
|
<span class="c1"># Make the Git repository non-bare and set HEAD</span>
|
|
git<span class="w"> </span>config<span class="w"> </span>--unset<span class="w"> </span>core.bare
|
|
jj<span class="w"> </span>new<span class="w"> </span>@-
|
|
</code></pre></div>
|
|
<p>We may officially support this in the future. If you try this, we would
|
|
appreciate feedback and bug reports.</p>
|
|
<h2 id="branches">Branches<a class="headerlink" href="#branches" title="Permanent link">¶</a></h2>
|
|
<p>TODO: Describe how branches are mapped</p>
|
|
<h2 id="format-mapping-details">Format mapping details<a class="headerlink" href="#format-mapping-details" title="Permanent link">¶</a></h2>
|
|
<p>Paths are assumed to be UTF-8. I have no current plans to support paths with
|
|
other encodings.</p>
|
|
<p>Commits created by <code>jj</code> have a ref starting with <code>refs/jj/</code> to prevent GC.</p>
|
|
<p>Commit metadata that cannot be represented in Git commits (such as the Change
|
|
ID and information about conflicts) is stored outside of the Git repo (currently
|
|
in <code>.jj/store/extra/</code>).</p>
|
|
<p>Commits with conflicts cannot be represented in Git. They appear in the Git
|
|
commit as as root directories called<code>.jjconflict-base-*/</code> and
|
|
<code>.jjconflict-side-*/</code>. Note that the purpose of this representation is only to
|
|
prevent GC of the relevant trees; the authoritative information is in the
|
|
Git-external storage mentioned in the paragraph above. As long as you use <code>jj</code>
|
|
commands to work with them, you won't notice those paths. If, on the other hand,
|
|
you use e.g. <code>git switch</code> to check one of them out, you will see those
|
|
directories in your working copy. If you then run e.g. <code>jj status</code>, the
|
|
resulting snapshot will contain those directories, making it look like they
|
|
replaced all the other paths in your repo. You will probably want to run
|
|
<code>jj abandon</code> to get back to the state with the unresolved conflicts.</p>
