[04:48:44] <bawolff>	 This is kind of interesting, [[File:OBR_Hannvoer_2024.webm]] has a different SHA-1, last modify date, and file size then what MW thinks the file should be. I think when the user tried to upload a new version, it failed part way through, and MW had a rollback but swift did not
[04:52:10] <bawolff>	 whole bunch of failed sync check in the log for that file
[05:02:33] <bawolff>	 And its actual length seems different then what a HEAD request says for content-length
[07:10:28] <Bsadowski1>	 weird
[07:59:11] <Nemo_bis>	 worrisome 
[08:01:46] <Nemo_bis>	 presumably it will cause an error for media backups? https://phabricator.wikimedia.org/T262668
[08:49:02] <bawolff>	 There's further context about the image on my commons talk page. But yeah definitely weird how this didn't exactly fail safe
[08:49:54] <bawolff>	 Or fail atomicly i guess i should say. The failure mode does seem safe
[08:50:50] <bawolff>	 I added more debugging to chunked upload which should go live on wed... maybe that will reveal what is going on with this person's attempted large uploads
[09:15:03] <p858snake|cloud>	 bawolff: broken images in swift? never!
[09:15:37] <bawolff>	 lol
[09:16:50] <tgr>	 bawolff: T153565 is the generic task
[09:16:51] <stashbot>	 T153565: MediaWiki file operations are fragile, causing occasional data loss - https://phabricator.wikimedia.org/T153565
[09:17:28] <tgr>	 FileBackend had some (untested) journaling functionality for a while, but it never got enabled on Wikimedia wikis and was eventually removed, IIRC
