[Merge] lp:~jtv/launchpad/katie-and-gina-are-bad-bad-girls into lp:launchpad
Jeroen T. Vermeulen has proposed merging lp:~jtv/launchpad/katie-and-gina-are-bad-bad-girls into lp:launchpad.
Requested reviews:
Launchpad code reviewers (launchpad-reviewers)
For more details, see:
https://code.launchpad.net/~jtv/launchpad/katie-and-gina-are-bad-bad-girls/+merge/75472
= Summary =
Katie and Gina are a bit of a mess. Very old code, basically unmaintained for years, full of sometimes puzzling XXX comments by people who no longer work here.
== Proposed fix ==
Remove some unneeded functions, parameters etc. Oh yes, and this revealed that the katie module was not only unclear and untested, it was unneeded as well.
Gina could do with more cleanups that will reverberate throughout the module. For example, it would help to look up the relevant distroseries once and pass that around, rather than passing distro and series name and expect every callee to look it up for themselves.
== Pre-implementation notes ==
We may be able to ditch the Katie database as well. The Katie celebrity may be slightly harder to get rid of, because Translations uses it as a special person to recognize items produced by a particular internal process.
We'll also want much more fine-grained transaction management in gina. It could run for far too long without committing its changes, and as far as I can see, without good reason. The code will behave fine if restarted after an abortive run that committed only a portion of its changes; it's integral to the design of incremental imports.
== Implementation details ==
I removed the bit in SourcePackageData that handles an Uploaders key in an incoming file and sets self.uploaders. I can do that because nothing references the value, and there is a catch-all (a dubious one though—need to look into that as well) that will naturally do the right thing for this item. It just won't parse the field, which is fine by me.
== Tests ==
{{{
./bin/test -vvc lp.soyuz -t katie -t gina
}}}
== Demo and Q/A ==
We can do this on dogfood; we have some experience running gina now. Run the old gina (“./scripts/gina.py -v sid”). Record resulting SourcePackagePublishingHistory and SourcePackageRelease information for Debian in a scratch table. Upgrade the codebase and run the new gina. Now compare: it should not affect SPPH and SPR statuses and versions.
This is not a very complete test, but since this is not a functional change, the main worry is something blowing up because of, for example, an incorrect argument count.
