<p>
|

You can examine build history output from the command line or
|
||
from a web interface.
|
||
</p>
|
||
<p>
|
||
To see any changes that have occurred (assuming you have
|
||
<code class="filename">BUILDHISTORY_COMMIT = "1"</code>), you can simply
|
||
use any Git command that allows you to view the history of
|
||
a repository.
|
||
Here is one method:
|
||
</p>
|
||
<pre class="literallayout">
|
||
$ git log -p
|
||
</pre>
|
||
<p>
|
||
You need to realize, however, that this method does show
|
||
changes that are not significant (e.g. a package's size
|
||
changing by a few bytes).
|
||
</p>
|
||
<p>
|
||
A command-line tool called <code class="filename">buildhistory-diff</code>
|
||
does exist though that queries the Git repository and prints just
|
||
the differences that might be significant in human-readable form.
|
||
Here is an example:
|
||
</p>
|
||
<pre class="literallayout">
|
||
$ ~/poky/poky/scripts/buildhistory-diff . HEAD^
|
||

|
||

|
||
* PV changed from "0.1.10" to "0.1.12"
|
||
</pre>
|
||
<p>
|
||
</p>
|
||
<p>
|
||
To see changes to the build history using a web interface, follow
|
||
the instruction in the <code class="filename">README</code> file here.
|
||
<a class="ulink" href="http://git.yoctoproject.org/cgit/cgit.cgi/buildhistory-web/" target="_self">http://git.yoctoproject.org/cgit/cgit.cgi/buildhistory-web/</a>.
|
||
</p>
|
||
<p>
|
||
Here is a sample screenshot of the interface:
