[bitbake-devel] RFC: Web Hob development

[Lv, XiaotongX]

Hi,



We are developing Web based Hob for Yocto v1.3, and so far the initial demonstration is ready. The code repo is @ (http://git.yoctoproject.org/cgit/cgit.cgi/poky-contrib/log/?h=xtlv/webhob-v0.1 ).

With Web Hob, users can customize the image in a browser, but before that, administrators should follow the steps to set up the server for users.



 In the repo. it makes up of 2 parts. the 2 parts needs to run separately. one is for bitbake. another is the code based on django framework. django codes only for testing. so the codes is messy.



1. required software and python library.

         a. django python library(1.3.1 version, download link, http://www.djangoproject.com/download/1.3.1/tarball/)

         b. webpy python library( git clone git://github.com/webpy/webpy.git )

         c. Browse r(it must support html 5, we had better use firefox and chrome for the this demo)

         d. mysql (version >=5.0)

2. setup

         2.1 mysql configurations

                   a. If u have installed mysql. Pls find 'my.cnf' file to edit. fedora system in /etc/my.cnf, add this statement 'max_allowed_packet=50M' in this file.

                       [root at lxt ~]$ vim /etc/my.cnf

                       [mysqld]

                       datadir=/var/lib/mysql

                      socket=/var/lib/mysql/mysql.sock

                      user=mysql

                      max_allowed_packet=50M

                .............

       b. create a database named 'bitbake'. import database file in repo @/poky-contrib/bitbake/lib/bb/ui/django_webhob/bitbake.sql.

       c. modify 'settings.py' file in repo @/poky-contrib/bitbake/lib/bb/ui/django_webhob/settings.py.

         find 'STATIC_ROOT = /home/xiaotong/workspace/python/poky-contrib/bitbake/lib/bb/ui/django_webhob/static/'

                             'TEMPLATE_DIRS = ('/home/xiaotong/workspace/python/poky-contrib/bitbake/lib/bb/ui/django_webhob/template'

         Modify your real path, for example: '/home/xxxxxxxx/ poky-contrib/bitbake/lib/bb/ui/django_webhob/static/'

3. run bitbake with restful helper and django

         a. to start bitbake with webhob helper, the command is: bitbake 127.0.0.1:8080 -u webhob

         b. to run django web server. switch the directory to '@/poky-contrib/bitbake/lib/bb/ui/django_webhob/', then using the command:

             [xiaotong at lxt django_webhob] python manage.py runserver 127.0.0.1:8000



         If anything is OK. Open ur browser to visit http://localhost:8000<http://localhost:8000/>.

4. bitbake restful helper apis:

     start bitbake with bitbake 127.0.0.1:8080 -u webhob. then u can open the folllowing restful links.
