Mike Lang	b0ded641c3	Add a logging handler which counts logs for prometheus stats ... This isn't as good as having a full centralised logging system, but should suffice to know if anything funny is happening.	6 years ago

Mike Lang	6815924097	Fix some bugs and linter errors introduced by backfiller ... I ran `pyflakes` on the repo and found these bugs: ``` ./common/common.py:289: undefined name 'random' ./downloader/downloader/main.py:7: 'random' imported but unused ./backfiller/backfiller/main.py:150: undefined name 'variant' ./backfiller/backfiller/main.py:158: undefined name 'timedelta' ./backfiller/backfiller/main.py:171: undefined name 'sort' ./backfiller/backfiller/main.py:173: undefined name 'sort' ``` (ok, the "imported but unused" one isn't a bug, but the rest are) This fixes those, as well as a further issue I saw with sorting of hours. Iterables are not sortable. As an obvious example, what if your iterable was infinite? As a result, any attempt to sort an iterable that is not already a friendly type like a list or tuple will result in an error. We avoid this by coercing to list, fully realising the iterable and putting it into a form that python will let us sort. It also avoids the nasty side-effect of mutating the list that gets passed into us, which the caller may not expect. Consider this example: ``` >>> my_hours = ["one", "two", "three"] >>> print my_hours ["one", "two", "three"] >>> backfill_node(base_dir, node, stream, variants, hours=my_hours, order='forward') >>> print my_hours ["one", "three", "two"] ``` Also, one of the linter errors was non-trivial to fix - we were trying to get a list of hours (which is an api call for a particular variant), but at a time when we weren't dealing with a single variant. My solution was to get a list of hours for ALL variants, and take the union.	6 years ago
