820 You can specify more than one --tags and/or --branches options, in case
821 your Subversion repository places tags or branches under multiple paths.
822 The option --stdlayout is
823 a shorthand way of setting trunk,tags,branches as the relative paths,

886 This allows one to specify a prefix which is prepended

888 specified. The prefix does not automatically include a
889 trailing slash, so be sure you include one in the
890 argument if that is what you want. If --branches/-b is
891 specified, the prefix must include a trailing slash.
892 Setting a prefix (with a trailing slash) is strongly
893 encouraged in any case, as your SVN-tracking refs will
894 then be located at "refs/remotes/$prefix/<strong>", which is
895 compatible with Git&#8217;s own remote-tracking ref layout
896 (refs/remotes/$remote/</strong>). Setting a prefix is also useful
897 if you wish to track multiple projects that share a common
898 repository.
899 By default, the prefix is set to <em>origin/</em>.

2019 This is especially helpful when we&#8217;re tracking a directory

2277 standard layout, it cannot yet represent merge history that happened
2278 inside git back upstream to SVN users. Therefore it is advised that

2284 <h2 id="_handling_of_svn_branches">HANDLING OF SVN BRANCHES</h2>
2285 <div class="sectionbody">
2286 <div class="paragraph"><p>If <em>git svn</em> is configured to fetch branches (and --follow-branches
2287 is in effect), it sometimes creates multiple Git branches for one
2288 SVN branch, where the additional branches have names of the form
2289 <em>branchname@nnn</em> (with nnn an SVN revision number). These additional
2290 branches are created if <em>git svn</em> cannot find a parent commit for the
2291 first commit in an SVN branch, to connect the branch to the history of
2292 the other branches.</p></div>
2293 <div class="paragraph"><p>Normally, the first commit in an SVN branch consists
2294 of a copy operation. <em>git svn</em> will read this commit to get the SVN
2295 revision the branch was created from. It will then try to find the
2296 Git commit that corresponds to this SVN revision, and use that as the
2297 parent of the branch. However, it is possible that there is no suitable
2298 Git commit to serve as parent. This will happen, among other reasons,
2299 if the SVN branch is a copy of a revision that was not fetched by <em>git
2300 svn</em> (e.g. because it is an old revision that was skipped with
2301 <code>--revision</code>), or if in SVN a directory was copied that is not tracked
2302 by <em>git svn</em> (such as a branch that is not tracked at all, or a
2303 subdirectory of a tracked branch). In these cases, <em>git svn</em> will still
2304 create a Git branch, but instead of using an existing Git commit as the
2305 parent of the branch, it will read the SVN history of the directory the
2306 branch was copied from and create appropriate Git commits. This is
2307 indicated by the message "Initializing parent: &lt;branchname&gt;".</p></div>
2308 <div class="paragraph"><p>Additionally, it will create a special branch named
2309 <em>&lt;branchname&gt;@&lt;SVN-Revision&gt;</em>, where &lt;SVN-Revision&gt; is the SVN revision
2310 number the branch was copied from. This branch will point to the newly
2311 created parent commit of the branch. If in SVN the branch was deleted
2312 and later recreated from a different version, there will be multiple
2313 such branches with an <em>@</em>.</p></div>
2314 <div class="paragraph"><p>Note that this may mean that multiple Git commits are created for a
2315 single SVN revision.</p></div>
2316 <div class="paragraph"><p>An example: in an SVN repository with a standard
2317 trunk/tags/branches layout, a directory trunk/sub is created in r.100.
2318 In r.200, trunk/sub is branched by copying it to branches/. <em>git svn
2319 clone -s</em> will then create a branch <em>sub</em>. It will also create new Git
2320 commits for r.100 through r.199 and use these as the history of branch
2321 <em>sub</em>. Thus there will be two Git commits for each revision from r.100
2322 to r.199 (one containing trunk/, one containing trunk/sub/). Finally,
2323 it will create a branch <em>sub@200</em> pointing to the new parent commit of
2324 branch <em>sub</em> (i.e. the commit for r.200 and trunk/sub/).</p></div>

2329 <div class="sectionbody">
2330 <div class="paragraph"><p>For the sake of simplicity and interoperating with Subversion,
2331 it is recommended that all <em>git svn</em> users clone, fetch and dcommit
2332 directly from the SVN server, and avoid all <em>git clone</em>/<em>pull</em>/<em>merge</em>/<em>push</em>
2333 operations between Git repositories and branches. The recommended
2334 method of exchanging code between Git branches and users is
2335 <em>git format-patch</em> and <em>git am</em>, or just 'dcommit&#8217;ing to the SVN repository.</p></div>
2336 <div class="paragraph"><p>Running <em>git merge</em> or <em>git pull</em> is NOT recommended on a branch you
2337 plan to <em>dcommit</em> from because Subversion users cannot see any
2338 merges you&#8217;ve made. Furthermore, if you merge or pull from a Git branch
2339 that is a mirror of an SVN branch, <em>dcommit</em> may commit to the wrong
2340 branch.</p></div>
2341 <div class="paragraph"><p>If you do merge, note the following rule: <em>git svn dcommit</em> will
2342 attempt to commit on top of the SVN commit named in</p></div>

2344 <div class="content">
2345 <pre><code>git log --grep=^git-svn-id: --first-parent -1</code></pre>

2347 <div class="paragraph"><p>You <em>must</em> therefore ensure that the most recent commit of the branch
2348 you want to dcommit to is the <em>first</em> parent of the merge. Chaos will
2349 ensue otherwise, especially if the first parent is an older commit on
2350 the same SVN branch.</p></div>
2351 <div class="paragraph"><p><em>git clone</em> does not clone branches under the refs/remotes/ hierarchy or
2352 any <em>git svn</em> metadata, or config. So repositories created and managed with
2353 using <em>git svn</em> should use <em>rsync</em> for cloning, if cloning is to be done
2354 at all.</p></div>
2355 <div class="paragraph"><p>Since <em>dcommit</em> uses rebase internally, any Git branches you <em>git push</em> to
2356 before <em>dcommit</em> on will require forcing an overwrite of the existing ref
2357 on the remote repository. This is generally considered bad practice,
2358 see the <a href="git-push.html">git-push(1)</a> documentation for details.</p></div>
2359 <div class="paragraph"><p>Do not use the --amend option of <a href="git-commit.html">git-commit(1)</a> on a change you&#8217;ve
2360 already dcommitted. It is considered bad practice to --amend commits
2361 you&#8217;ve already pushed to a remote repository for other users, and
2362 dcommit with SVN is analogous to that.</p></div>
2363 <div class="paragraph"><p>When cloning an SVN repository, if none of the options for describing
2364 the repository layout is used (--trunk, --tags, --branches,
2365 --stdlayout), <em>git svn clone</em> will create a Git repository with
2366 completely linear history, where branches and tags appear as separate
2367 directories in the working copy. While this is the easiest way to get a
2368 copy of a complete repository, for projects with many branches it will
2369 lead to a working copy many times larger than just the trunk. Thus for
2370 projects using the standard directory structure (trunk/branches/tags),
2371 it is recommended to clone with option <code>--stdlayout</code>. If the project
2372 uses a non-standard structure, and/or if branches and tags are not
2373 required, it is easiest to only clone one directory (typically trunk),
2374 without giving any repository layout options. If the full history with

2380 use <em>init</em> to set up your Git repository then, before your first <em>fetch</em>, edit
2381 the $GIT_DIR/config file so that the branches and tags are associated
2382 with different name spaces. For example:</p></div>
