TASK DESCRIPTION The line https://github.com/mineo/mb2wikidatabot/blob/master/bot/const.py#L36 sometimes causes the whole python interpreter to block, so it doesn't even exit on ^C anymore. Since this might be a very specific problem related to the order things are imported in etc., here's a rough overview of how that line is reached. https://github.com/mineo/mb2wikidatabot/blob/master/run.py is the main entry point of the bot, which imports https://github.com/mineo/mb2wikidatabot/blob/master/bot/common.py, which (in line 8) imports the `const.py` file. I've added print statements around every statement in `const.py` and the one before the creation of the ItemPage is the last one that gets executed. I have now found a reliable way to fix this and that is the execution of a file that contains only the following code (yes, this is basically a variation of the `const.py` file): ``` import pywikibot as wp WIKIDATA = wp.Site('wikidata', 'wikidata') WIKIDATA_DATASITE = WIKIDATA.data_repository() MUSICBRAINZ_WIKIDATAPAGE = wp.ItemPage(WIKIDATA_DATASITE, "Q14005") MUSICBRAINZ_CLAIM = wp.Claim(WIKIDATA_DATASITE, "P248") ``` Other ways to fix it include deletions of most files in the pywikibot user directory and/or random invokations of pywikibots `scripts/login.py` script. This happens on Python 2.6.5 on Ubuntu 10.04.4 in a virtual environment. This has happened over the last few year every once in a while with different revisions of pywikibot, but I feel like it's now happening way more often. The currently used pywikibot version is 6b2e416b1bd67d16cf70f3c02420bd9124217a13.
