OBS Project structure and promotion

The Mer projects on OBS look like this:

Maemo:Mer:Stable
Maemo:Mer:Stable:HW:Beagle
Maemo:Mer:Stable:HW:N8x0

This means all devices will have the main 'Stable' repository and an appropriate HW repository.

The development area is expanded slightly:

Maemo:Mer:Devel:Apps
Maemo:Mer:Devel:Base
Maemo:Mer:Devel:MaemoCommon
Maemo:Mer:Devel:MaemoCommon:L10n
Maemo:Mer:Devel:UI
Maemo:Mer:Devel:HW:Beagle:Devel
Maemo:Mer:Devel:HW:N8x0:Devel

Details of packages in each area is given in thePackages pages.

Packages in each of these Devel subproject areas can be hacked on and then, when they're kinda working they are consolidated into the :Devel area (which is used as a build target for the :Devel:* subprojects)

Maemo:Mer:Devel
Maemo:Mer:Devel:HW:N8x0
Maemo:Mer:Devel:HW:Beagle

Packages are placed in :Testing with the intention of including them in the next release subject to QA and bug fixes

 Maemo:Mer:Testing
 Maemo:Mer:Testing:HW:Beagle
 Maemo:Mer:Testing:HW:N8x0

Once :Testing is ready a release of all packages to a numbered version is made:

 Maemo:Mer:0.13
 Maemo:Mer:0.13:HW:Beagle
 Maemo:Mer:0.13:HW:N8x0

Note that the :HW promotion process is slightly different:

Maemo:Mer:Devel:HW:N8x0:Devel -> Maemo:Mer:Devel:HW:N8x0 -> Maemo:Mer:Testing:HW:N8x0 -> Maemo:Mer:Stable:HW:N8x0

Promotion Tasks

To promote a package:

 osc copypac <SOURCEPRJ> <SOURCEPAC> <DESTPRJ>

eg:

 osc copypac Maemo:Mer:Devel glib2.02 Maemo:Mer:Testing

Ensure that:

 osc meta prjconf <SOURCE>

is copied to the <TARGET> conf. This may contain things like package selection preferences. Currently the prjconf is:

 Prefer: hildon-fm-l10n-mr0
  Ignore: hildon-fm-l10n-mr

To Promote :Devel To :Testing

First pipe over the project metadata:

 osc meta prjconf Maemo:Mer:Devel  | osc meta prjconf Maemo:Mer:Testing -F - 

Then run:

 for i in $(osc ls Maemo:Mer:Devel); do echo $i; osc copypac Maemo:Mer:Devel $i Maemo:Mer:Testing ; done
 for HW in HW:N8x0 HW:SmartQ HW:Freerunner HW:Beagle; do
   for i in $(osc ls Maemo:Mer:Devel:$HW); do echo $i; osc copypac -k Maemo:Mer:Devel:$HW $i Maemo:Mer:Testing:$HW ; done
 done

To Promote :Testing to :Stable

The process here is to create a versioned repo; eg :0.14

 export STABLE=0.14

Create the projects (copied from 0.13):

 osc meta prj Maemo:Mer:0.13 | sed "s/0.13/$STABLE/" |osc meta prj Maemo:Mer:$STABLE -F -
 for HW in HW:N8x0 HW:SmartQ HW:Freerunner HW:Beagle; do
   osc meta prj Maemo:Mer:0.13:$HW | sed "s/0.13/$STABLE/" |osc meta prj Maemo:Mer:$STABLE:$HW -F -
 done

Pipe over the project metadata:

 osc meta prjconf Maemo:Mer:Testing  | osc meta prjconf Maemo:Mer:$STABLE -F - 

Then run:

 for i in $(osc ls Maemo:Mer:Testing); do echo $i; osc copypac Maemo:Mer:Testing $i Maemo:Mer:$STABLE ; done
 for HW in HW:N8x0 HW:SmartQ HW:Freerunner HW:Beagle; do
   for i in $(osc ls Maemo:Mer:Testing:$HW); do echo $i; osc copypac Maemo:Mer:Testing:$HW $i Maemo:Mer:$STABLE:$HW ; done
 done

Then, once it's built and stable, use _aggregate to link each package to :Stable

First clean out :Stable

 for i in $(osc ls Maemo:Mer:Stable); do osc deletepac Maemo:Mer:Stable $i ; done
 for HW in HW:N8x0 HW:SmartQ HW:Freerunner HW:Beagle; do
   for i in $(osc ls Maemo:Mer:Stable:$HW); do echo $i; osc deletepac Maemo:Mer:Stable:$HW $i; done
 done

NOTE The following uses -m in osc which is not accepted upstream yet. It will not work unless you have lbt's osc patches.

 for i in $(osc ls Maemo:Mer:$STABLE); do osc aggregatepac Maemo:Mer:$STABLE $i Maemo:Mer:Stable; done
 for HW in HW:N8x0 HW:SmartQ HW:Freerunner HW:Beagle; do
   for i in $(osc ls Maemo:Mer:$STABLE:$HW); do echo $i
     osc aggregatepac -m MerStable_Debian_5.0=Mer${STABLE}_Debian_5.0,MerStable_Ubuntu_9.04=Mer${STABLE}_Ubuntu_9.04 Maemo:Mer:${STABLE}:$HW $i Maemo:Mer:Stable:$HW
   done
 done

Note that :Stable project must be setup to publish and to build

Linking

To link to a source create a _link file containing:

 <link project="linked project name" package="linked package name">

optionally:

 <patches>
   <apply name="name of the first patch" />
 </patches>

Sadly these patches apply to the files in the source; so this means you need to apply the diff to the maemo-ised diff file.
