[Merge] lp:~adeuring/launchpad/cronscript-for-hwdb-report-fixes into lp:launchpad
Abel Deuring has proposed merging lp:~adeuring/launchpad/cronscript-for-hwdb-report-fixes into lp:launchpad.
Requested reviews:
Launchpad code reviewers (launchpad-reviewers)
For more details, see:

This branch converts scripts/reprocess-hwdb-submissions.py into cronscripts/reprocess-hwdb-submissions.py.
We need to reprocess a larger number of reports to the hardware database, coming from checkbox in Lucid, Marvierick and Natty, which could not be processed due to, well... a number of reasons. The core fixes which allow to process these submissions are already merged, but we want to include data from those reports that are marked as bad.
The number of these reports is in the order of 10**5 -- more than should be done in a single script run. The idea of the script simple: Run a query like
SELECT ... FROM HWSubmission WHERE id > (variable number) AND status=(bad) LIMIT whatever;
in a TunableLoop: The first run should begin with the first bad report that could come from Lucid; it tries to process a number of reports and records the ID of the last touched report. In the next run, it continues with higher IDs.
(variable number) above is stored in a file; when the script starts, it reads the value from the file; when it finishes, it writes a new value into the same file.
The test test_run_reprocessing_script_two_batches() turned out to be quite useful. It reveealed that the lines removed below:

were nonsense: The method __call__() can terminate before all submissions from a chunk have been processed: When the number of already processed submissions goes beyond self.max_submissions:
if self.max_submissions is not None:
if self.max_submissions <= (
self.valid_submissions + self.invalid_submissions):

The new tests look a bit odd: All except one are disabled. I described the reason in bug 849056...
