Hacking OfflineIMAP
|
||||
===================
|
||||
|
||||
Welcome to the `OfflineIMAP`_ project. You'll find here all the information you
|
||||
need to start hacking OfflineIMAP. Be aware there are a lot of very usefull tips
|
||||
in the mailing list. You may want to subscribe if you didn't, yet. This is
|
||||
where you'll get help.

Git: Branching Model And Workflow
|
||||
=================================
|
||||
|
||||
Introduction
|
||||
============
|
||||
|
||||
In order to involve into OfflineIMAP you need some knowledges about Git and our
|
||||
workflow. Don't be afraid if you don't know much, we would be pleased to help
|
||||
you.
|
||||
|
||||
You can find the API docs autogenerated on http://docs.offlineimap.org.
|
||||
|
||||
Release cycles
|
||||
==============
|
||||
|
||||
We use a classical cycle based workflow:
|
||||
|
||||
1. A stable release is out.
|
||||
|
||||
2. Feature topics are sent, discussed and merged.
|
||||
|
||||
3. When enough work was merged, we start the freeze cycle: the first release
|
||||
candidate is out.
|
||||
|
||||
4. During the freeze cycle, no more features are merged. It's time to test
|
||||
OfflineIMAP. New candidates version are released. The more we are late in -rc
|
||||
releases the less patches are merged but bug fixes.
|
||||
|
||||
5. When we think a release is stable enough, we restart from step 1.
|
||||
|
||||
|
||||
Branching model
|
||||
===============
|
||||
|
||||
The branching model with use in OfflineIMAP is very near from the Git project.
|
||||
We use a topic oriented workflow. A topic may be one or more patches.
|
||||
|
||||
The branches you'll find in the official repository are:
|
||||
|
||||
* gh-pages
|
||||
* master
|
||||
* next
|
||||
* pu
|
||||
* maint
|
||||
|
||||
gh-pages
|
||||
--------
|
||||
|
||||
This comes from a feature offered by Github. We maintain the online home github
|
||||
page using this branch.
|
||||
|
||||
master
|
||||
------
|
||||
|
||||
If you're not sure what branch you should use, this one is for you. This is the
|
||||
mainline. Simple users should use this branch to follow OfflineIMAP's evolution.
|
||||
|
||||
Usually, patches submitted to the mailing list should start off of this branch.
|
||||
|
||||
next
|
||||
----
|
||||
|
||||
Patches recently merged are good candidates for this branch. The content of next
|
||||
is merged into the mainline (master) at release time for both stable and -rc
|
||||
releases.
|
||||
|
||||
When patches are sent to the mailing list, contributors discuss about them. Once
|
||||
done and when patches looks ready for mainline, patches are first merged into
|
||||
next. Advanced users and testers use this branch to test last merged patches
|
||||
before they hit the mainline. This helps not introducing strong breackages
|
||||
directly in master.
|
||||
|
||||
pu
|
||||
--
|
||||
|
||||
pu stands for "proposed updates". If a topic is not ready for master nor next,
|
||||
it may be merged into pu. This branch only help developers to work on someone
|
||||
else topic or an earlier pending topic.
|
||||
|
||||
This branch is **not intended to be checkouted**; never. Even developers don't
|
||||
do that. Due to the way pu is built you can't expect content there to work in
|
||||
any way... unless you clearly want to run into troubles.
|
||||
|
||||
Developers can extract a topic from this branch to work on it. See the following
|
||||
section "Extract a topic from pu" in this documentation.
|
||||
|
||||
maint
|
||||
-----
|
||||
|
||||
This is the maintenance branch. It gets its own releases starting from an old
|
||||
stable release. It helps both users having troubles with last stable releases
|
||||
and users not wanting latest features or so to still benefit from strong bug
|
||||
fixes and security fixes.
|
||||
|
||||
|
||||
Working with Git
|
||||
================
|
||||
|
||||
Extract a topic from pu
|
||||
-----------------------
|
||||
|
||||
pu is built this way::
|
||||
|
||||
git checkout pu
|
||||
git reset --keep next
|
||||
git merge --no-ff -X theirs topic1
|
||||
git merge --no-ff -X theirs topic2
|
||||
git merge --no-ff -X theirs blue
|
||||
git merge --no-ff -X theirs orange
|
||||
...
|
||||
|
||||
As a consequence:
|
||||
|
||||
1. Each topic merged uses a merge commit. A merge commit is a commit having 2
|
||||
ancestors. Actually, Git allows more than 2 parents but we don't use this
|
||||
feature. It's intended.
|
||||
|
||||
2. Paths in pu may mix up multiple versions if all the topics don't use the same
|
||||
base commit. This is very often the case as topics aren't rebased: it guarantees
|
||||
each topic is strictly identical to the last version sent to the mailing list.
|
||||
No surprise.
|
||||
|
||||
|
||||
What you need to extract a particular topic is the sha1 of the tip of that
|
||||
branch (the last commit of the topic). Assume you want the branch of the topic
|
||||
called 'blue'. First, look at the log given by this command::
|
||||
|
||||
git log --reverse --merges --parents origin/next..origin/pu
|
||||
|
||||
With this command you ask for the log:
|
||||
|
||||
* from next to pu
|
||||
* in reverse order (older first)
|
||||
* merge commits only
|
||||
* with the sha1 of the ancestors
|
||||
|
||||
In this list, find the topic you're looking for, basing you search on the lines
|
||||
like::
|
||||
|
||||
Merge branch 'topic/name' into pu
|
||||
|
||||
By convention, it has the form <author_initials>/<brief_title>. When you're at
|
||||
it, pick the topic ancestor sha1. It's always the last sha1 in the line starting
|
||||
by 'commit'. For you to know:
|
||||
|
||||
* the first is the sha1 of the commit you see: the merge commit
|
||||
* the following sha1 is the ancestor of the branch checkouted at merge time
|
||||
(always the previous merged topic or the ancien next in our case)
|
||||
* last is the branch merged
|
||||
|
||||
Giving::
|
||||
|
||||
commit sha1_of_merge_commit sha1_of_ancient_pu sha1_of_topic_blue
|
||||
|
||||
Then, you only have to checkout the topic from there::
|
||||
|
||||
git checkout -b blue sha1_of_topic_blue
|
||||
|
||||
and you're done! You've just created a new branch called "blue" with the blue
|
||||
content. Be aware this topic is almostly not updated against current next
|
||||
branch. ,-)

Git: OfflineImap's branching Model And Workflow

Introduction
|
||||
------------
|
||||
|
||||
This optional section provides you with information on how we use git
|
||||
branches and do releases. You will need to know very little about git
|
||||
to get started.
|
||||
|
||||
For the impatient, see the :ref:`contribution checklist` below.
|
||||
|

Git Branching model
|
||||
--------------------
|
||||
|
||||
OfflineIMAP uses the following branches:
|
||||
|
||||
* master
|
||||
* next
|
||||
* maint
|
||||
* (pu)
|
||||
* & several topic oriented feature branches. A topic may consist of
|
||||
one or more patches.

|

--------------
|

A typical release cycle works like this:
|

1. A stable release is out.

|

2. Feature topics are sent, discussed and merged.
|
