Bug ID: 58976
Summary: PreloadingItemGenerator crashes with NoPage exception
Product: Pywikibot
Version: core (2.0)
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: Unprioritized
Component: Wikidata
Assignee: [email protected]
Reporter: [email protected]
Classification: Unclassified
Mobile Platform: ---
The PreloadingItemGenerator does what the name suggests: Preload Wikidata items
so that these can be processed quickly.
When it encounters an item that has been deleted it crashes with a
"pywikibot.exceptions.NoPage: Page [[wikidata:-1]] doesn't exist." exception.
It shouldn't crash. It should either:
* Not preload the item and pass the empty item (and let downstream check)
* Skip the item
Probably best to have the same behavior as with the PreloadingPageGenerator (or
does that one crash too?)
Full trace:
