Qt 5.1(.1) migration plans and blockers

Registered by Timo Jyrinki

Qt 5.1(.1) migration plans and blockers.

Saucy feature freeze is here, but there are known bugs with Qt 5.1 (ppa:canonical-qt5-edgers/qt5-beta-proper) / Qt 5.1.1 (ppa:canonical-qt5-edgers/qt5-beta2). Qt 5.1.1 snapshots are essentially identical to final tarballs being released.


Qt 5.1.1 (usable PPA): ppa:canonical-qt5-edgers/qt5-beta-proper
Work-In-Progress PPA:s ( rebuilding with final tarballs, released 20130828 with 1 MacOS related commit difference to ~20130820 )

Upgrade instructions for 5.1.1~20130820 (mobile & desktop):

sudo apt-add-repository ppa:canonical-qt5-edgers/qt5-beta-proper
sudo apt-get update
sudo apt-get dist-upgrade
sudo reboot

To revert back to archive versions:

sudo ppa-purge ppa:canonical-qt5-edgers/qt5-beta-proper

== Known Issues ==

Generally works, but some issues, see https://bugs.launchpad.net/bugs/+bugs?field.tag=qt5.1

Bug #1214374: Include patch to Correct geometry for "@2x" pixmaps Fix Committed
Bug #1217335: qmenumodel fails to build on i386/amd64 against Qt 5.1.1 Fix Released
Bug #1215414: CMake path error in Qt 5.1.1 Fix Committed
Bug #1217693: webbrowser-app crash with Qt 5.1.1 [fixed with rebuild] Invalid

[Needs developer work]
See work items

== Why we need 5.1.1 ==

- QML/Scene Graph event loop rewrite that's more trustworthy
- input support for accented characters
- possible to drop qtquick1 from SDK
- ...

== Potential Issues ==

- Additional issues may be found with more/formal testing like http://iso.qa.ubuntu.com/qatracker/milestones/270/builds/50650/testcases - will these be executed?
- Builds failing against 5.1.1? Looks quite good! Mostly everything builds: http://is.gd/5Calkj (builds against qt5-beta2, don't confuse with ongoing new 5.1.1 final builds / dependency waits) + http://is.gd/PuhaYi

== Status Document and Uploading ==

- Going forward with Qt 5.1.1? Consensus is yes. FFe will be needed.
- Detailed status document and upload order to Ubuntu:

4 rebuilds needed: qtubuntu, qtubuntu-sensors, unity8, webbrowser-app. https://code.launchpad.net/~canonical-qt5-edgers/+recipes
