l.r.s.p.DSDUpdater(TunableLoop) : class documentation

Part of lp.registry.scripts.populate_distroseriesdiff View In Hierarchy

Call DistroSeriesDifference.update() where appropriate.

The DistroSeriesDifference records we create don't have their details filled out, such as base version or their diffs.

Since this is likely to be much, much slower than the rest of the work of creating and initializing DistroSeriesDifference`s, it is done in a `DBLoopTuner.

Method	__init__	See `TunableLoop`.
Method	isDone	See `ITunableLoop`.
Method	__call__	See `ITunableLoop`.
Method	_cutChunk	Cut a chunk of up to `chunk_size` items from the remaining work.
Method	_getBatch	Retrieve a batch of `DistroSeriesDifference`s with given ids.
