Revision as of 11:03, 29 June 2009
The Maemo version of Qt lives here:
http://gitorious.org/+qt-maemo-developers/qt/qt-maemo
If you have a local clone you can use gitk --all
to see a visual representation of the branches, commits and merges.
lbt proposed this explanation of the branches/workflow based on the Mer gitorious workflow
Contents |
Origin
The branches are synced with upstream Qt changes. No Maemo changes are there at all.
master
represents the latest core Qt master branch (currently 4.6)
4.5
represents the latest core Qt branch for 4.5
Maemo master branches
Currently we have 4.5 master branch only.
master-maemo-qt-45
This branch is based on 4.5 and has all feature branches selected for maemo merged into it. Note that this branch is fairly plain Qt and should contains no packaging data and debian/* should not exist.
If an updates is made to 4.5 and 4.5 is merged into master-maemo-qt-4.5 then *all* conflicts with all feature/bug branches will be seen at once. To avoid this, 4.5 is merged into each bug/feature branch and conflicts resolved in focused feature areas. Now we need to merge the conflict-resolved features into master-maemo-qt-4.5. At this point it may seem reasonable to simply re-merge each feature branch into master-maemo-qt-4.5 however master-maemo-qt-4.5 contains all the other features from the last merge. So as soon as the first conflict-resolved feature is merged, all the conflicts from all the other features will be hit. The answer is to create a temporary local branch based on the latest 4.5 (see http://wiki.maemo.org/Mer/Build/UsingGitorious#Upstream_Updates) and merge each feature in turn into this branch. Then merge that into master-maemo-qt-4.5 (which should have no conflicts at all and, in the absence of any features/bugs is a simple fast-forward).
Maemo build branches
These branch should be built completely and used for regular release. There are based on master-maemo-qt-45 currently.
qt-diablo
Diablo branch
qt-fremantle
Fremantle branch, but this is not ready yet.
qt-mer
Currently there is no branch.
Maemo build script and debian folder
maemo-build-generic
This branch is based on and tracks ??(I suggest master-maemo-qt-4.5) It contains common packaging (ie debian/*) that allows Qt to build on various maemo-ish releases. A good rule is that no code is touched by non-merge commits to this branch It simply merges master-maemo-qt-4.5
maemo-build-diablo
Branched from maemo-build-generic and modified with packaging/configuration specifically used for diablo Note that maemo-build-diablo is not merged back
maemo-build-fremantle
Branched from maemo-build-generic and modified with packaging/configuration specifically used for fremantle
maemo-build-mer
Branched from maemo-build-generic and modified with packaging/configuration specifically used for Mer
maemo-qt-scripts
There are some scripts to manage maemo branches or create release pacakge etc.
Maemo fixes
These branches have each feature/ bug fix only. In the future, we will create a new maemo master branch, e.g. based on 4.6, at that time it is easy to chery-pick the modification to the new master branch.
bug-*
Representing potential bugs in Qt These branches hold fixes to specific bugs. The 4.5 branch will be merged into them to keep them up-to-date. If the bug is fixed upstream the branch will be deleted.
hildon-*
Each of these branches contain changes able to integrate Qt in the hildon environment. (Input method, menus, style). TO FIX: Actually the widget-* branches shoul be renamed in hildon-widget-*
hw-*
Contain changes that improve the usability of Qt with touchscreen device. Feature like right mouse button emulation, easy double click and so on. TO FIX: Actually the ts-* branches should be renamed in hw-ts-*
maemo-*
Representing features in various areas and branched from cloned 4.5 branch. Each branches adds only one feature-area.
The main covered areas are: - maemo-build-* - maemo-qt-scripts - others maemo related areas.
