Bazaar, the version control system¶
The new development process uses Bazaar via launchpad.net instead of Subversion. Bazaar offers flexibility with this distributed model. You can see our branches on https://code.launchpad.net/~openerp.
- Explanation of directories:
Two teams have been created on launchpad:
OpenERP quality teams --> they can commit on:
OpenERP-commiter --> They can commit on:
In this group, we include some of our partners who will be selected on merit by the quality team.
Contributors --> They can commit on:
- How can I be included in OpenERP-commiter team ?
To become a committer a contributor must show interest on working for openerp project and ability to do it properly as selection is based on merit. It can be by proposing bug fixes, features requested on our bug tracker system. You can even suggest additional modules and/or functionality on our bug tracker system.
- How can I suggest some additional modules or functionality ?
To create additional modules and/or functionality and include them in the project:
open a branch in launchpad
report and suggest your work via your new branch to our bug tracker system (there are two ways: bugs report for bug and blueprint for idea / functionality)
wait for approval by our quality team
Or the quality team approved your work and merge it into the official branch (like explained in the bug tracker section), or they refuse it and ask you to improve your work before merging it in our official branch.
Get Bazaar version control to pull the source from Launchpad.
To install bazaar on any ubuntu distribution, you can edit /etc/apt/sources.list by
sudo gedit /etc/apt/sources.list
and put these lines in it:
deb http://ppa.launchpad.net/bzr/ubuntu intrepid main deb-src http://ppa.launchpad.net/bzr/ubuntu intrepid main
Then, do the following
sudo apt-get install bzr
To work correctly, bzr version must be at least 1.3. Check it with the command:
If you have an older version check this url: http://bazaar-vcs.org/Download On debian, in any distribution, the 1.5 version is working, you can get it on this url: http://backports.org/debian/pool/main/b/bzr/bzr_1.5-1~bpo40+1_i386.deb
If you experience problems with Bazaar, please read the F.A.Q on Bazaar version control system before asking any questions.
This is the official and proposed way to contribute on OpenERP and OpenObject.
To download the latest sources and create your own local branches of OpenERP, do this:
mkdir openerp cd openerp bzr branch lp:~openerp/openobject-server/trunk server bzr branch lp:~openerp/openobject-addons/trunk addons bzr branch lp:~openerp-commiter/openobject-addons/trunk-extra-addons addons-extra bzr branch lp:~openerp-community/openobject-addons/trunk-addons-community addons-community bzr branch lp:~openerp/openerp-web/trunk web bzr branch lp:~openerp/openobject-client/trunk client bzr branch lp:~openerp-community/openobject-doc/6.1 doc
This will download all components of openerp (server, client, addons) and create links of modules in addons on your server so that you can use it directly. You can change the bzr_set.py file to select what you want to download exactly. Now, you can edit the code and commit in your local branch.:
EDIT addons/account/account.py cd addons bzr ci -m "Testing Modifications"
Once your code is good enough and follow the Coding Guidelines, you can push your branch in launchpad. You may have to create an account on launchpad first, register your public key, and subscribe to the openerp-community team. Then, you can push your branch. Suppose you want to push your addons:
cd addons bzr push lp:~openerp-community/openobject-addons/YOURLOGIN_YOURBRANCHNAME bzr bind lp:~openerp-community/openobject-addons/YOURLOGIN_YOURBRANCHNAME
After having done that, your branch is public on Launchpad, in the OpenObject project, and committers can work on it, review it and propose for integration in the official branch. The last line allows you to rebind your branch to the one which is on launchpad, after having done this, your commit will be applied on launchpad directly (unless you use --local):
bzr pull # Get modifications on your branch from others EDIT STUFF bzr ci # commit your changes on your public branch
If your changes fix a public bug on launchpad, you can use this to mark the bug as fixed by your branch:
bzr ci --fixes=lp:453123 # Where 453123 is a bug ID
Once your branch is mature, mark it as mature in the web interface of launchpad and request for merging in the official release. Your branch will be reviewed by a committer and then the quality team to be merged in the official release.
How to get the latest trunk source code¶
Get a clone of each repository:
bzr clone lp:~openerp/openobject-server/trunk server bzr clone lp:~openerp/openobject-client/trunk client bzr clone lp:~openerp/openobject-client-web/trunk client-web bzr clone lp:~openerp/openobject-addons/trunk addons
If you want to get a clone of the extra-addons repository, you can execute this command:
bzr clone lp:~openerp-commiter/openobject-addons/trunk-extra-addons extra-addons
run the setup scripts in the respective directories:
python2.5 setup.py build sudo python2.5 setup.py install
Currently the initialisation procedure of the server parameter --init=all to populate the database seems to be broken in trunk.
It is recommended to create a new database via the gtk-client. Until then the web-client will not work.
Start OpenERP server like this:
The bin/addons will be considered as default addons directory which can be overridden by the ~/home/workspace/stable/addons. That is if an addon exists in bin/addons as well as ~/home/workspace/stable/addons (custom path) the later one will be given preference over the bin/addons (default path).
How to commit Your Work¶
If you want to contribute on OpenERP or OpenObject, here is the proposed method:
You create a branch on launchpad on the project that interests you. It's important that you create your branch on launchpad and not on your local system so that we can easily merge, share code between projects and centralize future developments.
You develop your own features or bugfixes in your own branch on launchpad. Don't forget to set the status of your branch (new, experimental, development, mature, ...) so that contributors know what they can and cannot use.
Once your code is good enough, propose your branch for merging
Your work will be evaluated by a member of the committers team.
If they accept your branch for integration in the official version, they will submit to the quality team that will review and merge in the official branch.
If the commiter team refuses your branch, they will explain why so that you can review the code to better fit the guidelines (problem for future migrations, ...)
The extra-addons branch, that stores all extra modules, is directly accessible to all committers. If you are a committer, you can work directly on this branch and commit your own work. This branch does not require validation by the quality team. You should put there your special modules for your own customers.
If you want to propose or develop new modules, we suggest creating your own branch in the openobject-addons project and develop within your branch. You can fill in a bug to request that your modules are integrated in one of the two branches:
We invite all our partners and contributors to work in that way so that we can easily integrate and share the work done between the different projects.
Use Case Developers¶
This page presents the approach you should follow on how to contribute in OpenObject. Suppose you want to develop new features in the addons or simply correct some bugfixes.
If you have the right to modify the branch you plan to change, you can do it directly. For example, a quality team member doing a bugfix can do it directly on the main branch. Or committers can work directly on the extra-addons. If you don't have the right to modify the branch you plan to change or if you want to branch because you are starting big developments that may break the code, the first thing to do is to branch the repository you plan to modify:
bzr branch lp:openobject-addons lp:~openerp-commiter/openobject-addons/trunk-new-reporting
In that case, the branch created will be for the openerp-commiter team. If you are not a committer, you can create the branch for the community team openerp-community or just for yourself, depending if you allow others to directly commit on your branch or not. For all Tiny employees, we propose to create all branches for the team openerp-commiter. An OpenERP service company may create a team for their company and create branches at the name of their team. This prevents others changing their customer branch.
Once the branch is created, you must checkout a local copy to work on:
bzr co lp:~openerp-commiter/openobject-addons/trunk-new-reporting
This will download the branch on your local computer. You can then start developing on it. From time to time, you should commit the work done:
This will send your modification to the branch: lp:~openerp-commiter/openobject-addons/trunk-new-reporting. Don't forget to change the status of the branch to show other contributors the status of your current work on https://code.launchpad.net/~openerp-commiter/openobject-addons/trunk-new-reporting
For instance, you can switch the status to "In Development" to show you are working on it and put the status to "Mature" when you'd like to have your code integrated in the official release.
During your development, if you want to receive the latest modifications from the parent branches, you can merge it:
Once your development on this branch are OK, you can ask a committer to review and merge it or fill in a bug in the bugtracker. A committer will then review your work and merge it to the official branch if it's good enough.
When committing your work to Launchpad, please respect these policies:
The stable branch is for bugfixes¶
The stable branch must be used for bugfixes. Only bugfixes.
The new features (+the bugfixes on these new functionality) have to be done in the trunk branch.
We will periodically backport all the fixes from stable to trunk.
Write a helpful commit message¶
Use a commit tag in each message. This tag should be one of:
For bug fixes
For refactoring (improvements of the source code, without changing the functionality or behavior. See http://en.wikipedia.org/wiki/Refactoring for further details)
For adding new resources
For removing of resources
Always put a meaningful commit message. Commit message should be self explanatory including the name of the module that has been changed. No more "bugfix" or "improvements" anymore! (the only single word commit message accepted is "merge")
If you are fixing the bugs use --fixes=lp:<bug_number> instead of putting the number of the bug in the commit message.
Use the revision id instead of the revision number when you make reference to a revision in your commit message. You can get this revision id, by using the command bzr version-info.
e.g: Not Correct : bzr commit -m “[FIX]: reverted bad revision (cannot install new db) with revision number:525425” Correct : bzr commit -m “[FIX]: reverted bad revision (cannot install new db) with revision number id: firstname.lastname@example.org” Not Correct : bzr commit -m "Bug 568889 : typo corrected" Correct : bzr commit --fixes=lp:568889 -m "[FIX] account module: typo corrected"
How to handle translations ?
use [IMP] if you translated a message in a po file
use [ADD] if you added an new po file
Avoid big commits¶
Don't make a commit that will impact lots of modules. Try to split it into different commits where impacted modules are different (It will be helpful when we are going to revert that module separately).
