+<h3 id="How_can_I_diff_and_patch_files.3F" name="How_can_I_diff_and_patch_files.3F">How can I diff and patch files?</h3>
+<ul>
+ <li><code>hg diff</code> diffs the entire tree by default. Use <code>hg diff &lt;dir&gt;</code> to diff only the given directory. Don't forget to <code>hg add</code> any new files you are adding before generating the patch.</li>
+ <li>If you are changing binary files or renaming files you may want to use git style patches with <code>hg diff -g</code> to retain that sort of information in the patch.</li>
+ <li>When applying a patch generated by Mercurial, use <code>patch -p1</code>, not <code>patch -p0</code>. (This is due to a quirk of Mercurial diff output—it refers to fictional "a" and "b" directories. Don't ask.).</li>
+ <li>If you have a git style patch with renames and/or binary changes you can use <code>hg import --no-commit</code> to apply the patch to your tree or use <code>hg qimport</code> to import the patch to mq.</li>
+ <li>There's <a class="link-https" href="https://hg.mozilla.org/users/robarnold_cmu.edu/qimportbz" title="https://hg.mozilla.org/users/robarnold_cmu.edu/qimportbz">hg qimportbz extension</a> (<a class="external" href="http://robarnold.org/2009/06/02/hg-qimport-my-bugzilla-patch-redux.html" title="http://robarnold.org/2009/06/02/hg-qimport-my-bugzilla-patch-redux.html">blog post</a>) that lets you import patches directly from bugzilla to mq.   (Since that blog post was written, the command syntax has changed.  It is now: <code>hg qimport <a class="external" rel="freelink">bz://1234567</a></code>)</li>
+ <li>If you have it, <code>git-apply</code> can also be used to apply patches. It can handle most forms of Mercurial diff output, but it won't automatically tell Mercurial about added, copied, removed or renamed files, and it cannot reverse binary changes (except to remove added binary files).</li>
+</ul>
+<p>Preferred diff options are <code>hg diff -p -U 8</code> which includes 8 lines of context and shows the relevant function for the block. You can make these options default in the <a class="internal" href="/en/Mercurial_FAQ#Configuration" title="en/Mercurial FAQ#Configuration">Mercurial configuration file</a>.</p>
+<h3 id="How_can_I_generate_a_patch_for_somebody_else_to_check-in_for_me.3F" name="How_can_I_generate_a_patch_for_somebody_else_to_check-in_for_me.3F">How can I generate a patch for somebody else to check-in for me?</h3>
+<p>If you don't have commit access yourself, you need to attach your patches to a bug for somebody to check in.  In order to do that, you should make sure that your patch has the following conditions:</p>
+<ol>
+ <li>It has a correctly formatted author name.</li>
+ <li>It has a correctly formatted commit message.</li>
+ <li>It is generated in git style.</li>
+</ol>
+<p>Here is a very easy way to get this setup working using <a class="external" href="http://www.selenic.com/mercurial/wiki/index.cgi/MqExtension" style="">mq</a>.  First, you need to edit your <code>~/.hgrc</code> file.  You only need to do this once.  Your hgrc file should have the following contents at least:</p>
+<pre>[ui]
+username = John Smith &lt;john@smith.com&gt;
+
+[defaults]
+qnew = -Ue
+
+[extensions]
+mq =
+
+[diff]
+git = 1
+showfunc = 1
+unified = 8
+</pre>
+<p>Now, in order to create a patch, you should enter:</p>
+<pre>hg qnew name.patch
+</pre>
+<p>which opens up your favorite editor so that you can enter a good commit message.  A good sample commit message looks like: "Bug 123456 - Change this thing to work better by doing something; r=reviewers".  You don't need to enter the final commit message (for example, if you haven't received reviews yet).  You can edit the commit message of the current <code>mq</code> patch at any time using <code>hg qref -e</code>.</p>
+<p>The <code>~/.hgrc</code> default <code>-U</code> argument for the qnew command add the author information to the patch (using a <code>From:</code> header), and the default <code>-e</code> argument opens up the editor for you to type in a commit message.</p>
+<p>Now, after editing some source code, you can use <code>hg qref</code> to update your patch file.</p>
+<p>To attach the patch to the bug, you can use the file named <code>name.patch</code> located in your <code>&lt;repository&gt;/.hg/patches</code> directory directly.</p>
+<h3 id="How_do_I_check_stuff_in.3F" name="How_do_I_check_stuff_in.3F">어떻게 변경 내용을 적용(check in)하나요?</h3>
+<h4 id="Required_configuration" name="Required_configuration">필수 설정</h4>
+<p>변경 내용을 커밋하기 전에 이 내용을 <code>~/.hgrc</code> 파일에 추가해야 합니다:</p>
+<pre class="eval">[ui]
+username = Your Name &lt;<a class="link-mailto" href="mailto:your.email@example.com" rel="freelink">your.email@example.com</a>&gt;
+</pre>
+<p><a href="/en/mozilla-central" title="en/mozilla-central">mozilla-central</a>이나 다른 mozilla-hosted 저장소에 변경내용을 올리기 위해서는 커밋 권한을 가지고 있어야 하고 <code><em>(your-local-hg-root)</em>/.hg/hgrc</code> (<code>~/.hgrc</code> 파일이 <strong>아닙니다</strong>) 파일에 다음의 내용을 넣어야 합니다:</p>
+<pre class="eval">[paths]
+default = <span class="nowiki">http://hg.mozilla.org/mozilla-central/</span>
+<strong>default-push = <span class="nowiki">ssh://hg.mozilla.org/mozilla-central/</span></strong>
+</pre>
+<p>또한 ssh에 hg.mozilla.org에 접속할 사용자 이름이 무엇인지 알려주어야 합니다. 이 이름은 Mozilla LDAP 계정과 연결된 사용자 이름이어야 합니다. 이를 위해서 위에 있는 default-push 경로는 좀 더 복잡하게 만들거나 (<code><span class="link-mailto">user@host.name</span>@hg.mozilla.org</code>) ~/.ssh/config에 다음 내용을 넣어서 해결할 수 있습니다:</p>
+<pre class="eval">Host hg.mozilla.org
+User <a class="link-mailto" href="mailto:user@host.domain" rel="freelink">user@host.domain</a>
+</pre>
+<h4 id="Check_what_you.27re_going_to_commit" name="Check_what_you.27re_going_to_commit">커밋하려고 하는 내용 확인</h4>
+<p>다음으로 정말로 커밋하고자 하는 내용을 커밋하게 될 것인지 확인합니다(특히나 다른 까다로운 커밋을 머지할 때에 중요합니다):</p>
+<pre class="eval">hg status
+hg diff
+</pre>
+<p><code>status</code> 명령어는 작업 디렉토리의 변경된 내용이 있는 파일과 저장소(부모 리비전으로서 <code>hg parents</code>를 이용해서 볼 수 있습니다)에 있는 내용을 비교해서 보여줍니다. <code>hg diff</code>는 이 파일들의 실제 변경 내역을 하나의 diff로 보여줍니다. 더 자세한 내용을 보기 위해서 -U8 옵션을 설정할 수 있습니다.</p>
+<h4 id="Commit_to_the_local_repository" name="Commit_to_the_local_repository">로컬 저장소에 커밋</h4>
+<p>다음 단계로 변경내용을 <em>로컬 저장소에 커밋</em>합니다:</p>
+<pre class="eval">hg commit
+</pre>
+<p>이렇게 하면 <code>hg status</code>로 보고된 변경내용을 매번 커밋합니다. <code>hg commit <em>filenames</em></code>을 이용해서 특정 파일이나 디렉토리만 커밋 할 수 있습니다. <code>hg commit -u "Someone Else &lt;<a class="link-mailto" href="mailto:someone@example.com" rel="freelink">someone@example.com</a>&gt;"를 사용해서 다른사람을 대신해서 커밋할 수도 있습니다</code>. 더 자세한 내용은 <code>hg help commit</code>을 살펴보세요.</p>
+<p>새로운 파일을 저장소에 추가된고 필요없는 파일을 지우려면 다음 명령어를 사용하세요.</p>
+<pre class="eval">hg addremove
+</pre>
+<h4 id="Check_what_you.27re_going_to_push" name="Check_what_you.27re_going_to_push">푸시하려는 내용 확인</h4>
+<p>푸시를 하기 전에 어떠한 변경내용(changeset)이 푸시될지 확인할 수 있습니다.<code> 이를 위해서 outgoing</code> 명령어를 사용합니다:</p>
+<pre class="eval">hg outgoing
+</pre>
+<p>이렇게 하면 기본 원격 저장소에 푸시할 변경내용의 목록을 보여줍니다. 다른 저장소에 푸시될 변경내용을 확인하려면 저장소 아규먼트를 추가합니다.</p>
+<h4 id="Push_to_the_central_repository" name="Push_to_the_central_repository">중앙 저장소에 푸시</h4>
+<p>중앙 저장소에 이 변경사항을들 푸시해서 올립니다:</p>
+<pre class="eval">hg push
+</pre>
+<h4 id="Preventing_accidental_pushes" name="Preventing_accidental_pushes">실수로 푸시하는 일 방지</h4>
+<p><code>qpush</code> 명령어가 쉽게 <code>push</code>로 잘못 입력될 수 있기 때문에, MQ 패치를 적용할 때 실수로 푸시를 하게될 수 있습니다. 실수로 푸시하는 일을 방지하기 위해서는 아래의 내용을 <code>~/.hgrc</code> 파일에 기입합니다:</p>
+<pre class="eval">[hooks]
+pre-push = read -p 'Are you sure you want to push to remote? (y/n): '; if test "$REPLY" != "y"; then echo 'Push cancelled'; exit 1; fi
+</pre>
+<p>이렇게 하면 <code>push</code> 명령어를 입력할 때 마다 사용자가 확인을 해야 하고 y 이외의 다른 내용을 입력하면 푸시가 취소됩니다.</p>
+<h3 id="How_do_I_deal_with_.22abort:_push_creates_new_remote_heads.21.22.3F" name="How_do_I_deal_with_.22abort:_push_creates_new_remote_heads.21.22.3F">How do I deal with "abort: push creates new remote heads!"?</h3>
+<p>Whatever you do, don't do 'push -f' like the message suggests. (It'll probably fail anyway, but don't try it.)</p>
+<p>Someone pushed new commits upstream since your last pull. You then committed your patch locally and are trying to push that commit upstream; that upstream has a different tip commit that you started from.</p>
+<pre> <strong>YOU</strong> ---&gt; o 9123b7791b52 - Kaitlin Jones <span class="plain">&lt;kaitlin@example.net&gt;</span> - Bug 123456 - Trebled fromps (r=gavin)

+<p>There are three things you can do. In all cases, you are strongly encouraged to take steps to back up your patch (perhaps by obtaining a diff: hg log -p -r 12345 to show the patch for rev 12345).</p>
+<h4 id="Using_hg_merge">Using <code>hg merge</code></h4>
+<p>Run <code>hg pull</code>, then <code>hg merge</code>. If there are any merge conflicts, hg will open a merge program to try to help you resolve them manually. (If you fail to make sense of the merge tool, that's OK.  Just close it; hg will detect that the conflicts weren't all resolved and spit out some <code>hg update -C</code> commands that you can use to undo and then retry the busted merge.)</p>
+<p>Even if there were no conflicts, you have to commit the merge: <code>hg commit -m "Merge bug 123456"</code>.</p>
+<pre> <strong>YOU</strong> ---&gt; <span style="background-color: rgb(255, 255, 0);">o</span> 1fe7659c29a9 - Kaitlin Jones <span class="plain">&lt;kaitlin@example.net&gt;</span> - Merge bug 123456.

+<p>Now you can <code>hg push</code> as normal.</p>
+<p>This leaves a merge commit in the log, which some people find annoying, so it's usually better to avoid this solution.</p>
+<p>If you decide to use this method, it is advantageous to enable the Mercurial <code>fetch</code> extension (by means of a <span style="background-color: #CCC;"><code>fetch =</code></span> line in the <span style="background-color: #CCC;"><code>[extensions]</code></span> section of your <code>&lt;repository&gt;/.hg/hgrc</code> or your <code>$HOME/.hgrc</code> file) so you can do the <code>pull + merge + commit</code> sequence in one step (assuming no merge conflicts) by using the <span style="background-color: #CCC;"><code>hg fetch</code></span> command.</p>
+<h4 id="Using_Mercurial_queues">Using Mercurial queues</h4>
+<p>A way to solve your problem without leaving a merge commit is to import your commit into <a class="external" href="http://www.selenic.com/mercurial/wiki/index.cgi/MqExtension" style="">mq</a> control, pop it off the queue, update, and then commit it again before pushing:</p>
+<pre class="eval">% <strong>hg log -l 5</strong>

+<em>Turn the new commit you made into a MQ patch</em>
+% <strong>hg qtop</strong>

+% <strong>hg qpop</strong>
+Patch queue now empty
+<em>Pop the MQ patch off the stack. At this point, the tip of your tree is also in the remote repository</em>
+% <strong>hg pull -u</strong>
+<em>... various pull/update messages ...</em>
+% <strong>hg qpush</strong>
+applying 415.diff
+Now at: 415.diff
+<em>Fix up conficts as necessary; if you fixed up any, run hg qrefresh first</em>
+% <strong>hg incoming</strong>

+<em>Make sure nobody pushed while you were merging. Otherwise, qpop, pull and qpush again</em>
+% <strong>hg qfinish 415.diff</strong>
+<em>Turn the MQ patch into a regular revision</em>
+% <strong>hg log -l 5</strong>
+<em>verify that the log looks good, with your commit on top</em>
+% <strong>hg push</strong>
+</pre>
+<p>If you already use mq to manage your patches, then just make sure you pull/update right before committing and pushing your patch. If you have problems with the above, it's ok to just do a simple merge as described previously.</p>
+<p>In this case, if there are merge conflicts, MQ will produce <code>.rej</code> files. Some people prefer this over being thrown into a merge program.</p>
+<h4 id="Using_hg_rebase">Using <code>hg rebase</code></h4>
+<p>(Requires Mercurial 1.1 or higher)</p>
+<p>This is the simplest and easiest way to deal with the problem. You can rebase your local changesets (including mq patches) on top of the tip using the <a class="external" href="http://www.selenic.com/mercurial/wiki/index.cgi/RebaseExtension" title="http://www.selenic.com/mercurial/wiki/index.cgi/RebaseExtension">rebase extension</a>. To do this, simply enable the extension by adding this to the following section of your <code>.hgrc</code>:</p>
+<pre class="eval">[extensions]
+hgext.rebase =
+</pre>
+<p>Now, type <code>hg pull --rebase <span style="font-family: sans-serif;">to pull and rebase your local changesets at the same time.</span></code> More details and options can be found at the <a class="external" href="http://www.selenic.com/mercurial/wiki/index.cgi/RebaseProject" title="http://www.selenic.com/mercurial/wiki/index.cgi/RebaseProject">Mercurial wiki</a>.</p>
+<p>If you have conflicting changes, you'll be thrown into your preferred merge tool.</p>
+<div class="note">
+ <strong>Note:</strong> As of Mercurial 1.1, rebasing (especially with mq patches) might lose rename data; this is a <a class="external" href="http://www.selenic.com/mercurial/bts/issue1423" title="http://www.selenic.com/mercurial/bts/issue1423">known bug</a> that has been fixed in Mercurial 1.3. </div>
+<div class="note">
+ <strong>Note:</strong> If you had done a normal <code>hg pull</code> without <code>--rebase</code> after your <code>hg commit</code>, you will have to first undo that by doing <code>hg rollback</code>. Only the very last action can be undone, so if you did anything else after the <code>hg pull</code>, you're out of luck.</div>
+<div class="note">
+ <strong>Note:</strong> If you have local changes, hg pull --rebase (just like hg merge) will refuse to work, so you'll have to revert your local changes first:</div>
+<pre class="note">hg diff &gt; old.diff
+hg revert .
+hg pull --rebase
+hg push
+patch -p 1 -i old.diff

+<p>If you want to see what <code>hg commit</code> will commit, run <code>hg diff</code> first.</p>
+<p>If you want to see what <code>hg push</code> will push, run <code>hg outgoing</code> first.</p>
+<p>If you want to see what <code>hg pull</code> will pull, run <code>hg incoming</code> first.</p>
+<p>These pairs of commands all take similar arguments, for good reason. These are a good idea to use all the time when you're learning mercurial. And even once you're an expert, always doing outgoing before push is a good idea.</p>
+<h3 id="How_can_I_customize_the_format_of_the_patches_Mercurial_creates.3F" name="How_can_I_customize_the_format_of_the_patches_Mercurial_creates.3F">How can I customize the format of the patches Mercurial creates?</h3>
+<p>Edit your <code>~/.hgrc</code> file and add some lines like these:</p>
+<pre class="eval">[defaults]
+diff=-U 8 -p
+qdiff=-U 8
+#for Mercurial 1.1 use:
+#qdiff=-U 8 -p</pre>
+<pre class="eval">[diff]
+git=true
+</pre>
+<p>The <code>{{ mediawiki.external('defaults') }}</code> section affects the default output of the <code>hg diff</code> and <code>hg qdiff</code> commands. The options behave the same as they would on the command line. Try <code>hg help diff</code> for more info.</p>
+<p>The <code>{{ mediawiki.external('diff') }}</code> section affects all patches generated by Mercurial, even <code>hg export</code> and those generated for Mercurial's internal use. You need to be a lot more careful with this, but <code>git=true</code> is recommended. Without it, Mercurial cannot diff binary files and does not track the execute mode bit.  You may want to add <code>showfunc=true</code> here to get diffs that show the function being changed in each hunk, and you may want to add <code>unified=8</code> to make all diffs (including the internal ones <a class="external" href="http://www.selenic.com/mercurial/wiki/index.cgi/MqExtension" style="">mq</a> uses) have 8 lines of context. Note that this may increase the risk of mq patches failing to apply!</p>
+<h3 id="How_do_I.C2.A0get_a_diff_-w.3F">How do I get a diff -w?</h3>
+<p>There is a <a class="external" href="http://www.selenic.com/mercurial/bts/issue127" title="http://www.selenic.com/mercurial/bts/issue127">known issue</a> where <code>hg diff -w</code> doesn't work.</p>
+<p>To get around this add the following to your <code>~/.hgrc</code> file, editing existing sections where applicable:</p>
+<pre>[extensions]
+hgext.extdiff =
+
+[extdiff]
+cmd.diffw = diff
+opts.diffw = -w -r -N -p -U 8
+</pre>
+<p>You can, of course, add your other favourite diff options to <code>opts.diffw</code>. Once you've added this, you will now have a new hg command, <code>hg diffw</code>.</p>
+<p>hg diffw -r -2 is the equivalent of hq qdiff -w for the topmost patch in the queue.</p>
+<h3 id="How_do_I_generate_a_bundle.3F">How do I generate a bundle?</h3>
+<p>Sometimes the tree will be under sheriff control, and they will specifically ask for a bundle.  If you don't have sufficient rights to push to mozilla-central, you might also generate bundles and attach them to bugs when you add checkin-needed to a bug after it has the necessary reviews and approval.</p>
+<p>Creating a bundle is quite simple.  Once you have your changes all done, commit them to your local repository.  You can also commit more than one changeset.  Once you have everything committed, instead of pushing you'll run <code>hg bundle</code>:</p>
+<pre>hg bundle outputfile.hg
+</pre>
+<p>By default, <code>hg bundle</code> will bundle everything that <code>hg outgoing</code> would display (and what you would push with <code>hg push</code>).  You can limit how far forward you want to bundle as well by specifying a revision with <code>-r</code>.  That will take all changes up until that revision.</p>

+<p>If you see this message:</p>

+<h2 id="Things_that_have_changed" name="Things_that_have_changed">Branch merges</h2>
+<p>As part of the rapid release process, the contents of e.g. mozilla-aurora and mozilla-beta are subject to merge events that happen according to the planned branch migration dates. After a branch merge event occurred, if you attempt to use "hg update" in your local tree, you may get error messages such as "abort: crosses branches". In order to fix it, first make sure you don't have local changes, then run "hg update -C -r default".</p>

+<p><code>hg pull</code> copies changesets from one repository to another.  It only brings changes into your local <em>repository</em>, not your working copy.  It will touch the network if you're pulling from a remote repository.</p>
+<p><code>hg update</code> updates your working copy.  It only modifies your working copy.  It will not touch the network (unless your directory is on a network filesystem).</p>

+<p>The Windows version of Mercurial does not automatically convert line endings between Windows and Unix styles. All our repositories use Unix line endings. We need a story for Windows, but right now I have no ideas.</p>
+<p>(How about a pre-commit hook that rejects pushes containing CR with a suitably informative error message? We possibly want to make exceptions for certain types of files (at least binary files of course), but we can tweak the hook as necessary as these crop up. Mercurial 1.0 adds a standard hook for this in the win32text extension that we could use/adapt. --jwatt)</p>
