[Bug 178102] Re: (Pro|De)motion loses arch: all binaries

[William Grant]

** Summary changed:

- (Quick) promotion and demotion can lose binaries
+ (Pro|De)motion loses arch: all binaries

** Description changed:

  For some reason, esound 0.2.38-0ubuntu4 was demoted almost 24 hours ago,
  and promoted again 3 hours later. Today we have massive uninstallability
  and FTBFSing, due to esound-common being... completely missing.
- 
- I suspect what happened is the following, though I can't see the code so it's a bit of an educated guess:
-  - Demotion requested
-  - Demotion sets the BinaryPackagePublishing in main to Superseded.
-  - Demotion checks if it's about to clobber an existing BinaryPackagePublishing in universe.
-  - Demotion doesn't find one, so creates a new Published one.
-  [3 hours pass]
-  - Promotion requested
-  - Promotion sets the universe one to Superseded.
-  - Promotion checks if it's about to clobber an existing BinaryPackagePublishing in main.
-  - Promotion finds the existing one (which was superseded 3 hours ago), so doesn't create a new one.
- 
- Here we have an unfortunate state where we (I presume) have two
- BinaryPackagePublishings which are marked Superseded. process-deathrow
- (or the binary equivalent) runs after a while, and obliterates both of
- them. I presume this situation won't occur (although it might - I'm not
- sure if a SourcePackageRelease has been demoted and promoted and just
- not been noticed) if deathrow is processed before the promotion, as the
- (de|pro)motion will hopefully realise that the BPP is deleted, and
- create a new one.
