Hi there, Hope I've found the correct list for asking this question.
I was setting up a CI test case for my MediaWiki Client Library to run a bot that will upload a file to https://en.wikipedia.beta.wmflabs.org in chunked stash mode. For most of the time, when I perform the final upload with filekey parameter, I will receive a fileexists-no-change error from the MW API server. This is expected, as there is already a same file with the same title on the site. However, today I received backend-fail-alreadyexists. The error message looks like backend-fail-alreadyexists: The file "mwstore://local-swift-eqiad/local-public/archive/9/95/20191116051316!Test_image.jpg" already exists. Does this error usually occurs when user tries to upload the same file? What's the difference between fileexists-no-change and backend-fail-alreadyexists? Thanks, Xinyan _______________________________________________ Wikitech-l mailing list Wikitechfirstname.lastname@example.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l
