Comment 2 for bug 588050

Yes, the getBuildSummariesForSourceIds() was originally created and exposed just for the PPA Ajax updating (which, by design, only shows you the one failed build in the UI, even if there are 4 successful), where we wanted the information only for the current batch of builds displayed on the page.

Now that it's being used for other things, I agree it should be generally useful (and the PPA page JS can be updated to only use the info it is interested in) - either that or we should think through a better solution to suit your needs... maybe simply: IArchive.getBuildSummaries() which returned a summary of the builds for all the currently published sources?
