If you get to a point that is important and you want to forever remember
|
||||
that specific commit snapshot, you can tag it with <code>git tag</code>.
|
||||
The <code>tag</code> command will basically put a permanent bookmark at
|
||||
a specific commit so you can use it to compare to other commits in the
|
||||
future. This is often done when you cut a release or ship something.
|
||||
</p>
|
||||
|
||||
<p>Let's say we want to release our Hello World project as version "1.0".
|
||||
We can tag the last commit (<code>HEAD</code>) as "v1.0" by running
|
||||
<code>git tag -a v1.0</code>. The <code>-a</code> means "make an annotated
|
||||
tag", which allows you to add a tag message to it, which is what you almost
|
||||
always want to do. Running this without the <code>-a</code> works too, but
|
||||
it doesn't record when it was tagged, who tagged it, or let you add a tag
|
||||
message. I would recommend always creating annotated tags.</p>
|
||||
|
||||
<pre>
|
||||
<b>$ git tag -a v1.0 </b>
|
||||
</pre>
|
||||
|
||||
<p>When you run the <code>git tag -a</code> command, Git will open your editor
|
||||
and have you write a tag message, just like you would write a commit
|
||||
message.</p>
|
||||
|
||||
<p>Now, notice when we run <code>git log --decorate</code>, we can see our
|
||||
tag there.</p>

<p>If we do more commits, the tag will stay right at that commit, so we have

|

<p>We don't have to tag the commit that we're on, however. If we forgot to

tag a commit that we released, we can retroactively tag it by running the

same command, but with the commit SHA at the end. For example, say we had
|
||||
released commit <code>558151a</code> (several commits back) but forgot to
|
||||
tag it at the time. We can just tag it now:</p>

So now you have a bunch of branches that you are using for short lived
|
||||
topics, long lived features and what not. How do you keep track of them?
|
||||
Git has a couple of tools to help you figure out where work was done, what
|
||||
the difference between two branches are and more.

<p>Cool.</p>
|
||||
<p>We've already seen how to use <code>git log</code> to compare branches,
|
||||
by looking at the commits on one branch that are not reachable from another.
|
||||
(If you don't remember, it looks like this: <code>git log branchA ^branchB</code>.
|
||||
However, you can also use <code>git log</code> to look for specific commits.
|
||||
Here we'll be looking at some of the more commonly used <code>git log</code>
|
||||
options, but there are many. Take a look at the official docs for the whole
|
||||
list.

<h4>
|

git log --author
|
||||
<small>look for only commits from a specific author</small>
|
||||
</h4>
|
||||
|
||||
<p>
|
||||
To filter your commit history to only the ones done by a specific author,
|
||||
you can use the <code>--author</code> option. For example, let's say we're
|
||||
looking for the commits in the Git source code done by Linus. We would
|
||||
type something like <code>git log --author=Linus</code>. The search is
|
||||
case sensitive and also will search the email address. I'll do the
|
||||
example using the <code>-[number]</code> option, which will limit the
|
||||
results to the last [number] commits.
|
||||

|

<p>
|
||||
If you want to specify a date range that you're interested in filtering your
|
||||
commits down to, you can use a number of options - I use <code>--since</code>
|
||||
and <code>--before</code>, but you can also use <code>--until</code> and
|
||||
<code>--after</code>. For example, if I wanted to see all the commits in
|
||||
the Git project before 3 weeks ago but after April 18th, I could run this
|
||||
(I'm also going to use <code>--no-merges</code> to remove merge commits):

You may also want to look for commits with a certain phrase in the commit

modified anything that looked like the function name

'userformat_find_requirements', we would run this: (note there is no '='

pretty: Initialize notes if %N is used
|

|

When using git log --pretty='%N' without an explicit --show-notes, git
|
||||
would segfault. This patches fixes this behaviour by loading the needed
|
||||
notes datastructures if --pretty is used and the format contains %N.
|
||||
When --pretty='%N' is used together with --no-notes, %N won't be
|
||||
expanded.

This is an extension to a proposed patch by Jeff King.

|

Each commit is a snapshot of the project, but since each commit records the
|
||||
snapshot it was based off of, Git can always calculate the difference and
|
||||
show it to you as a patch. That means for any commit you can get the patch
|
||||
that commit introduced to the project. You can either do this by running
|
||||
<code>git show [SHA]</code> with a specific commit SHA, or you can run
|
||||
<code>git log -p</code>, which tells Git to put the patch after each commit.
|
||||
It is a great way to summarize what has happened on a branch or between
|
||||
commits.

<p>Just like <code>git log</code>, you can use the <code>--stat</code>
|
||||
option with it.</p>
|
||||
|
||||
<pre>
|
||||
<b>$ git diff v0.9 --stat</b>
|
||||
README | 2 +-
|
||||
ruby.rb | 4 ++--
|
||||
2 files changed, 3 insertions(+), 3 deletions(-)
|
||||
</pre>
|
||||
|
||||
<p>To compare two divergant branches, however, you can run something like
|
||||
<code>git diff branchA branchB</code> but the problem is that it will do
|
||||
exactly what you are asking - it will basically give you a patch file that
|
||||
would turn the snapshot at the tip of branchA into the snapshot at the tip
|
||||
of branchB. This means if the two branches have diverged - gone in different
|
||||
directions - it will remove all the work that was introduced into branchA
|
||||
and then add everything that was introduced into branchB. This is probably
|
||||
not what you want - you want the changes added to branchB that are not in
|
||||
branchA, so you really want the difference between where the two branches
|
||||
diverged and the tip of branchB. So, if our history looks like this:</p>
|
||||
|
||||
<pre>
|
||||
<b>$ git log --graph --oneline --decorate --all</b>
|
||||
* 594f90b (HEAD, tag: v1.0, master) reverted to old class name
|
||||
| * 1834130 (erlang) added haskell
|
||||
| * ab5ab4c added erlang
|
||||
|/
|
||||
* 8d585ea Merge branch 'fix_readme'
|
||||
...
|
||||
</pre>
|
||||
|
||||
<p>And we want to see what is on the "erlang" branch compared to the "master"
|
||||
branch, running <code>git diff master erlang</code> will give us the wrong
|
||||
thing.</p>
|
||||
|
||||
<pre>
|
||||
<b>$ git diff --stat master erlang</b>
|
||||
erlang_hw.erl | 5 +++++
|
||||
haskell.hs | 4 ++++
|
||||
ruby.rb | 4 ++--
|
||||
3 files changed, 11 insertions(+), 2 deletions(-)
|
||||
</pre>
|
||||
|
||||
<p>You see that it adds the erlang and haskell files, which is what we did
|
||||
in that branch, but then the output also reverts the changes to the ruby file
|
||||
that we did in the master branch. What we really want to see is just the
|
||||
changes that happened in the "erlang" branch (adding the two files). We can
|
||||
get the desired result by doing the diff from the common commit they diverged
|
||||
from:</p>
|
||||
|
||||
<pre>
|
||||
<b>$ git diff --stat 8d585ea erlang</b>
|
||||
erlang_hw.erl | 5 +++++
|
||||
haskell.hs | 4 ++++
|
||||
2 files changed, 9 insertions(+), 0 deletions(-)
|
||||
</pre>
|
||||
|
||||
<p>That's what we're looking for, but we don't want to have to figure out
|
||||
what commit the two branches diverged from every time. Luckily, Git has a
|
||||
shortcut for this. If you run <code>git diff master...erlang</code> (with three dots in between the branch names), Git will automatically figure out
|
||||
what the common commit (otherwise known as the "merge base") of the two
|
||||
commit is and do the diff off of that.</p>
|
||||
|
||||
<pre>
|
||||
<b>$ git diff --stat master erlang</b>
|
||||
erlang_hw.erl | 5 +++++
|
||||
haskell.hs | 4 ++++
|
||||
ruby.rb | 4 ++--
|
||||
3 files changed, 11 insertions(+), 2 deletions(-)
|
||||
<b>$ git diff --stat master...erlang</b>
|
||||
erlang_hw.erl | 5 +++++
|
||||
haskell.hs | 4 ++++
|
||||
2 files changed, 9 insertions(+), 0 deletions(-)
|
||||
</pre>
|
||||
|
||||
<p>Nearly every time you want to compare two branches, you'll want to use
|
||||
the triple-dot syntax, because it will almost always give you what you want.
|
||||
</p>
|
||||
|
||||
<p>As a bit of an aside, you can also have git manually calculate the
|
||||
merge-base (first common ancestor commit) of any two commits would be with
|
||||
the <code>git merge-base</code> command:</p>
|
||||
|
||||
<pre>
|
||||
<b>$ git merge-base master erlang</b>
|
||||
8d585ea6faf99facd39b55d6f6a3b3f481ad0d3d
|
||||
</pre>
|
||||
|
||||
<p>So, you can do the equivalent of <code>git diff master...erlang</code>
|
||||
by running this:</p>
|
||||
|
||||
<pre>
|
||||
<b>$ git diff --stat $(git merge-base master erlang) erlang</b>
|
||||
erlang_hw.erl | 5 +++++
|
||||
haskell.hs | 4 ++++
|
||||
2 files changed, 9 insertions(+), 0 deletions(-)
|
||||
</pre>
|
||||
|
||||
<p>I would of course recommend using the easier syntax, though.</p>
|
||||
|
||||
|
||||
<p class="nutshell">
|
||||
<b>In a nutshell</b> you can use <code>git diff</code> to see how a project
|
||||
has changed since a known point in the past or to see what unique work is
|
||||
in one branch since it diverged from another. Always use
|
||||
<code>git diff branchA...branchB</code> to inspect branchB relative to
|
||||
branchA to make things easier.
