Looking at build history

Inspecting the Git directory with build history can be done in several ways:

Using Git tools such as gitk or git log
Using the buildhistory-diff command-line tool, which displays the differences in a human-readable format
Using a Django-1.8-based web interface

To install the Django web interface on a development machine, you first need to install some host dependencies:

$ sudo apt-get install python3-django 
$ sudo apt-get install python-django-registration

This will install Django 1.8 both for Python 2.7, and Python 3. The buildhistory-web interface will only currently work on Python 2.7 but the build history import script will need to run under Python 3 as that is what the Yocto 2.4 BitBake uses.

Now we can clone the web interface source and configure it:

$ cd /opt/yocto/fsl-community-bsp/sources
$ git clone git://git.yoctoproject.org/buildhistory-web
$ cd buildhistory-web/

Edit the settings.py file to change the path to the database engine:

    DATABASES = {                                                                   
        'default': {                                                                
            'ENGINE': 'django.db.backends.sqlite3',
            'NAME': '/opt/yocto/fsl-community-bsp/sources/buildhistory-web/bhtest.db3',
            'USER': '',
            'PASSWORD': '',
            'HOST': '',
            'PORT': '',
        }                                                                           
    }

You then need to set up the Django application with:

$ python manage.py migrate

Next, import buildhistory as follows:

$ python3 warningmgr/import.py  /opt/yocto/fsl-community-bsp/sources/poky/ /opt/yocto/fsl-community-bsp/wandboard/buildhistory/

The preceding command will need to be executed each time there is a new build.

And finally, start the web server on the localhost with:

$ python manage.py runserver

To bind it to a different IP address and port you can do:
$ python manage.py runserver <host>:<port> But you will need to configure your settings.py accordingly with:
ALLOWED_HOSTS = [u'<host>']
