[Merge] lp:~brian-murray/ubuntu-archive-tools/phased-updater into lp:ubuntu-archive-tools

[Brian Murray]

Brian Murray has proposed merging lp:~brian-murray/ubuntu-archive-tools/phased-updater into lp:ubuntu-archive-tools.

Requested reviews:
  Ubuntu Package Archive Administrators (ubuntu-archive)

This new tool, phased-updater, will be the glue between Launchpad (for setting the phased updater percentage) and the Ubuntu Error Tracker (for finding regressions in package from -updates).

In the event that no regressions (defined as errors about the version of the package in -updates that were not seen in the previous version, or an increased rate of crashes) are found about the package the phased-update-percentage for the package will be incremented by 10%.  If regressions are found the phased-update-percentage for the package will be set to 0%.  There is also a mechanism for indicating that individual buckets are not regressions in a particular version of the package.

In either case an html report (sample visible at http://people.canonical.com/~brian/tmp/phased-updates.html) will be generated that will display the phased update percentage for the package and any issues found with that package.  This will also be useful for seeing which packages are currently undergoing phasing.

In the event that a regression is found about a package in -updates the uploader and signer (if different from the uploader) wil be emailed of the regression or regressions in that upload.  There is a csv file used to keep track of email notifications sent to uploaders to ensure that we do not email them multiple times about the same issue.

Its possible to test this on dogfood by initially setting the phased update percentage to something less than one hundred percent and observe the script increment the phased update percentage.  However, this needs to be done using quantal and a start date in early May as the database for dogfood is rather old.
