[FFe] standing freeze exception in trusty for Ubuntu Touch-specific packages

[Didier Roche-Tolomelli]

Dear Release Team,

I would like to request a blanket FFe wrt Ubuntu Touch, for those packages that are part of Ubuntu Touch but not part of Ubuntu Desktop. TTBOMK, the packages that are different between the two are not otherwise used in other flavor images.

I've assembled a list of 136 source packages, included inline below, that would be affected by this. The script used to generate the list is included at the bottom.

For the vast majority of these packages, there is no expectation of freeze-breaking changes; but since there is a high probability that some critical features will not be landed by Feature Freeze for some subset of these packages, I think it makes sense to deal with these as a whole rather than requesting exceptions package-by-package or feature-by-feature.

You will notice as well that I didn't include Qt5 from the list, as they are going to have another FFe for it (see discussions on the devel ML about update to Qt 5.2) to separate concerns. I did the same for autopilot and Mir (as it's used as a prerequisite in term of testing or build-dependency on the desktop, but not installed in the seed).

Finally, I added the "android" package which isn't installed on the seed per say, but is used to build the image and provide the android part of the Touch image.

Script stolen from slangasek:
$ wget http://cdimage.ubuntu.com/daily-live/pending/trusty-desktop-amd64.manifest
$ wget http://cdimage.ubuntu.com/ubuntu-touch/daily-preinstalled/pending/trusty-preinstalled-touch-armhf.manifest
$ for F in $(sed -e's/[:[:space:]].*//' trusty-desktop-amd64.manifest); do grep-dctrl -X -n -FPackage -sSource:Package $F /var/lib/apt/lists/*trusty*binary-armhf_Packages | head -n 1; done | sort -u > trusty-desktop-sources
$ for F in $(sed -e's/[:[:space:]].*//' trusty-preinstalled-touch-armhf.manifest); do G=$(grep-dctrl -X -n -FPackage -sSource:Package $F /var/lib/apt/lists/*trusty*binary-armhf_Packages | head -n 1); if [ -z "$G" ]; then G=$F; fi; echo $G; done | sort -u > trusty-touch-sources
$ join -j1 -v2 trusty-desktop-sources trusty-touch-sources > only_touch

+ I added some seed checks to take into account other flavor seeds:
for P in $(cat only_touch); do O=$(seeded-in-ubuntu $P | egrep -v 'seeded|ubuntu-touch|supported'); if [ -z "$O" ]; then echo $P; fi; done

There's nothing here that looks like a problem to me. The CI process used on the phone images should be sufficient to ensure release quality without a freeze, and given that these packages aren't used on any other images, that should suffice.

I diffed the package list with the output of `generate-freeze-block -u
ubuntu-touch' (lp:~laney/ubuntu-archive-tools/generate-freeze-block) &
got the following:

The '+' lines are ones present in this exception but not unique to touch
- the only problem I can see is gsettings-ubuntu-touch-schemas. -hybris
  is a binary package, so that's probably an error.

The '-' lines are missed packages, AFAICT. You might want to add them.

for android/xpathselect: look at the rational on top of this bug report and in https://bugs.launchpad.net/ubuntu/+source/mir/+bug/1282593.

I removed qtxmlpatterns-opensource-src as per rationale (will be included in the Qt 5.2 one)

click-update-manager -> not sure which manifest it's based on, but this one has been dropped recently (see the email on the phone ML)

I'm happy if we add the others (libunwind and clickmanager-plugin). I still think that gsettings-ubuntu-touch-schemas, the binary is only used in touch.

I'm unsure why gsettings-ubuntu-schemas has gsettings-ubuntu-touch-schemas as a source, can the desktop team work on removing that so that we are not blocked to do a schema changed due to that?

Thanks for the updates. +1 for adding those two.

The schemas are now shared between desktop and touch. The old names are
now transitional packages to the new ones (s/-touch//).

Anyway, it doesn't make much sense to have a FFe for GSettings /
AccountsService schemas alone. I'd say that any FFe already granted
should attach to the schemas package. So this blanket exception covers
schema additions too implicitly, and any desktop-impacting features need
to be FFed explicitly, as normal.

Thanks.

I'd like to include ubuntu-push to the list of packages included in this FFe. It's a new package, providing ubuntu-push-client.

The ubuntu push client is an upstart-activated service that talks to network manager, the url dispatcher, and the notifications service via dbus, and to the ubuntu push server over tcp when possible. Having it installed should have no impact beyond notifying the user of available system updates using the push notifications system. Just in case it isn't clear yet, it's only really usable on touch.

The code, both client and server, is extensively covered by a series of unit and acceptance tests; we'll be increasing that coverage to include integration tests as soon as reasonable. We've worked with QA to ensure it's acceptable (and our work has been very well received there).

Thank you.

[Thomas Strehl (strehl-t)]

Ted was asking for adding url-dispatcher to the FFe but added it to old standing touch FFe (https://bugs.launchpad.net/ubuntu/+bug/1208989):

Discussed in #ubuntu-release, agreed to add url-dispatcher with the additional restriction that any ABI changes require an FFE due to dependencies of converged indicators.

[Sergio Schvezov (sergiusens)]

I'd like to add nuntium (new package written in golang), this package integrates with the ubuntu-download-manager, telepathy-ofono and ofono; it registers an agent against ofono to which ofono would send push notifications; nuntium should be capable of delivering and working with any type of push; but it's initial goal is to deliver and send MMS application type messages , it uses the download manager's go bindings to download and upload towards the ofono configured message center and notifies telepathy-ofono of newly available messages.

The nature of this package implies it's only target is ubuntu touch only. It being written in go implies that's it's a drop in binary.

[Bill Filler (bfiller)]

I'd like to add sync-monitor package as part of this FFe. It is a new package and will be used on touch only and is necessary for contact and calendar syncing. didrocks has already done the archive admin review and it's ready to go.

The package needs to be uploaded as part of Silo 9 on the CI Train:
