&lt;h1&gt;How to separate topic branches&lt;/h1&gt;
&lt;/div&gt;
&lt;div id=&quot;content&quot;&gt;
&lt;div id=&quot;preamble&quot;&gt;
&lt;div class=&quot;sectionbody&quot;&gt;
&lt;div class=&quot;paragraph&quot;&gt;&lt;p&gt;This text was originally a footnote to a discussion about the
behaviour of the git diff commands.&lt;/p&gt;&lt;/div&gt;
&lt;div class=&quot;paragraph&quot;&gt;&lt;p&gt;Often I find myself doing that [running diff against something other
than HEAD] while rewriting messy development history.  For example, I
start doing some work without knowing exactly where it leads, and end
up with a history like this:&lt;/p&gt;&lt;/div&gt;
&lt;div class=&quot;literalblock&quot;&gt;
&lt;div class=&quot;content&quot;&gt;
&lt;pre&gt;&lt;code&gt;    &quot;master&quot;
o---o
     \                    &quot;topic&quot;
      o---o---o---o---o---o&lt;/code&gt;&lt;/pre&gt;
&lt;/div&gt;&lt;/div&gt;
&lt;div class=&quot;paragraph&quot;&gt;&lt;p&gt;At this point, &quot;topic&quot; contains something I know I want, but it
contains two concepts that turned out to be completely independent.
And often, one topic component is larger than the other.  It may
contain more than two topics.&lt;/p&gt;&lt;/div&gt;
&lt;div class=&quot;paragraph&quot;&gt;&lt;p&gt;In order to rewrite this mess to be more manageable, I would first do
&quot;diff master..topic&quot;, to extract the changes into a single patch, start
picking pieces from it to get logically self-contained units, and
start building on top of &quot;master&quot;:&lt;/p&gt;&lt;/div&gt;
&lt;div class=&quot;literalblock&quot;&gt;
&lt;div class=&quot;content&quot;&gt;
&lt;pre&gt;&lt;code&gt;$ git diff master..topic &amp;gt;P.diff
$ git checkout -b topicA master
... pick and apply pieces from P.diff to build
... commits on topicA branch.&lt;/code&gt;&lt;/pre&gt;
&lt;/div&gt;&lt;/div&gt;
&lt;div class=&quot;literalblock&quot;&gt;
&lt;div class=&quot;content&quot;&gt;
&lt;pre&gt;&lt;code&gt;      o---o---o
     /        &quot;topicA&quot;
o---o&quot;master&quot;
     \                    &quot;topic&quot;
      o---o---o---o---o---o&lt;/code&gt;&lt;/pre&gt;
&lt;/div&gt;&lt;/div&gt;
&lt;div class=&quot;paragraph&quot;&gt;&lt;p&gt;Before doing each commit on &quot;topicA&quot; HEAD, I run &quot;diff HEAD&quot;
before update-index the affected paths, or &quot;diff --cached HEAD&quot;
after.  Also I would run &quot;diff --cached master&quot; to make sure
that the changes are only the ones related to &quot;topicA&quot;.  Usually
I do this for smaller topics first.&lt;/p&gt;&lt;/div&gt;
&lt;div class=&quot;paragraph&quot;&gt;&lt;p&gt;After that, I&amp;#8217;d do the remainder of the original &quot;topic&quot;, but
for that, I do not start from the patchfile I extracted by
comparing &quot;master&quot; and &quot;topic&quot; I used initially.  Still on
&quot;topicA&quot;, I extract &quot;diff topic&quot;, and use it to rebuild the
other topic:&lt;/p&gt;&lt;/div&gt;
&lt;div class=&quot;literalblock&quot;&gt;
&lt;div class=&quot;content&quot;&gt;
&lt;pre&gt;&lt;code&gt;$ git diff -R topic &amp;gt;P.diff ;# --cached also would work fine
$ git checkout -b topicB master
... pick and apply pieces from P.diff to build
... commits on topicB branch.&lt;/code&gt;&lt;/pre&gt;
&lt;/div&gt;&lt;/div&gt;
&lt;div class=&quot;literalblock&quot;&gt;
&lt;div class=&quot;content&quot;&gt;
&lt;pre&gt;&lt;code&gt;                        &quot;topicB&quot;
       o---o---o---o---o
      /
     /o---o---o
    |/        &quot;topicA&quot;
o---o&quot;master&quot;
     \                    &quot;topic&quot;
      o---o---o---o---o---o&lt;/code&gt;&lt;/pre&gt;
&lt;/div&gt;&lt;/div&gt;
&lt;div class=&quot;paragraph&quot;&gt;&lt;p&gt;After I am done, I&amp;#8217;d try a pretend-merge between &quot;topicA&quot; and
&quot;topicB&quot; in order to make sure I have not missed anything:&lt;/p&gt;&lt;/div&gt;
&lt;div class=&quot;literalblock&quot;&gt;
&lt;div class=&quot;content&quot;&gt;
&lt;pre&gt;&lt;code&gt;$ git pull . topicA ;# merge it into current &quot;topicB&quot;
$ git diff topic
                        &quot;topicB&quot;
       o---o---o---o---o---* (pretend merge)
      /                   /
     /o---o---o----------'
    |/        &quot;topicA&quot;
o---o&quot;master&quot;
     \                    &quot;topic&quot;
      o---o---o---o---o---o&lt;/code&gt;&lt;/pre&gt;
&lt;/div&gt;&lt;/div&gt;
&lt;div class=&quot;paragraph&quot;&gt;&lt;p&gt;The last diff better not to show anything other than cleanups
for crufts.  Then I can finally clean things up:&lt;/p&gt;&lt;/div&gt;
&lt;div class=&quot;literalblock&quot;&gt;
&lt;div class=&quot;content&quot;&gt;
&lt;pre&gt;&lt;code&gt;$ git branch -D topic
$ git reset --hard HEAD^ ;# nuke pretend merge&lt;/code&gt;&lt;/pre&gt;
&lt;/div&gt;&lt;/div&gt;
&lt;div class=&quot;literalblock&quot;&gt;
&lt;div class=&quot;content&quot;&gt;
&lt;pre&gt;&lt;code&gt;                        &quot;topicB&quot;
       o---o---o---o---o
      /
     /o---o---o
    |/        &quot;topicA&quot;
o---o&quot;master&quot;&lt;/code&gt;&lt;/pre&gt;
&lt;/div&gt;&lt;/div&gt;
&lt;/div&gt;
&lt;/div&gt;
&lt;/div&gt;
