The BackendPackage Cache

Each Package has one BackendPackage which serves as cache for additional backend Package data (srcmd5, verifymd5 etc.). For invalidating/refreshing this cache there are several jobs

UpdatePackageMetaJob

If an IssueTracker is saved:

• Creates BackendPackage if it does not exist for all Package that are links
• Deletes BackendPackage of all Package that are not links
• Schedules an UpdatePackagesIfDirtyJob for all Projects that contain Packages without BackendPackages

PackageUpdateIfDirtyJob(package)

Creates BackendPackage if it does not exist for Package if sources changed (Package.sources_changed is called manually)

UpdateBackendInfosJob(package)

Refreshes (deletes/creates) BackendPackage everytime the Backend changed the sources (New Event for new revision, service run, undelete).

UpdatePackagesIfDirtyJob(project)

Creates BackendPackage if it does not exist for all Packages in Project
