Dependencies

First you need to get all the dependencies installed

On Ubuntu, type the following:

   sudo apt-get install python python-gtk2 python-zopeinterface python-psycopg2 python-imaging \
     python-reportlab postgresql postgresql-client python-dateutil python-mako python-gudev \
     python-poppler python-webkit python-twisted-core python-twisted-web librsvg2-common python-xlwt \
     gettext intltool git git-review python-setuptools pep8 pyflakes python-mock pylint python-storm

Downloading the Stoq sources

This is easiest to do using is using the Repo instructions or you can try using the outdated Stoq plugin for git.

It'll download the source for stoq, stoqdrivers and kiwi and help you setup the environment variables and other things needed to run stoq smoothly:

Configuring postgresql

You can configure postgresql in a few different way, the easiest is to just create a new database user. To be compatible with the wizard you'll need to create a user with the same username as yours.

On a Debian/Ubuntu system this is accomplished with:

 sudo -u postgres createuser -ds $USER

For other systems, just su / sudo to the postgres user and run createuser -ds

Configuring stoq

When you created a user you need to create an initial stoq.conf, this is easiest to do by using the first time wizard in stoq. It will automatically run if you haven't started stoq before or if you have an empty ~/.stoq directory.

Starting stoq

Then it's enough to just start stoq

 stoq

Developer options:

 --sql = show all sql commands
 --debug = run in pdb and enable a few debugging only features

Administrating the database

stoqdbadmin contains a couple of commands that will help the development and administration of your stoq database

Pass in -v se be more verbose.

shell

Creates a database shell where you can type SQL commands.

console

Create a python console with a stoq environment fully setup where you for instance can manipulate domain objects.

updateschema

Update the database schema to the latest version

Pass in the -b option to avoid creating a backup

init

Creates a new database.

Pass in the -e option to also create a set of examples, good for developer testing.

This is also used to remove the existing database, when you need to reset it for some reason. But be careful.

Now when you're done here, head over to Documentation and start learning how the different Stoq components are related.

Working with Git

Submitting patches

  • Create an account on Gerrit
  • Add your SSH key
  • Change-Id

Gerrit adds a commit hook (in .git/hooks/commit-msg) to add a Change-Id line which is then used to identify the gerrit issue with a specific git commit. Gerrit will not add a Change-Id if one already exists in a commit.

Sometimes you need to remove the Change-Id manually, for example when you want to change the branch you submitted your patch to. Eg, it was first target to go into the branch release-1, but then it changed and you want to push it to release-2.

  • Uploading a patch

If you are using repo (Repo instructions), you can send your changes with the command:

 $ repo upload

Or if you used the git-stoq integration you will have a branch called review, then you can just do

 $ git review

to get the patch uploaded.

This is the same as doing (in a more verbose way):

 $ git push ssh://gerrit.async.com.br:29418/stoq.git HEAD:refs/for/master

That submits your current working tree (HEAD) for review (refs/for) in the master branch (/master)

  • git commit --amend

If you need to update a patch you first modify your source tree and then amend the patch to the previous commit. This is done so that the Change-Id gerrit added is the same.

Remember to git add all the modified files or add the -a flag to git commit (all files)

  • update for review

If you want to update patch, you just submit it again, via git-review

  • Gerrit: rebase button

If a patch you depended on changed somehow you might need to rebase it. That can be done by downloading the patch and running rebase normally.

Alternatively you can just click on the rebase button in the ui and it will do it for you.

Submitting code

  • Once the code has passed the tests (so the verified flag is set) and a reviewer has approved the code

it will be integrated. Someone has to push the 'submit' button for that to happen.
