MatthewVernon added a comment to T360589: De-fragment thumbnail sizes in mediawiki.

This seems broadly sensible - what's the concrete proposal in terms of which thumb sizes will be supported/generated?

MatthewVernon added a comment to T345334: Cache thumbs in our caching infrastructure (e.g. ATS).

One thing that was discussed at the SRE meeting in Warsaw was looking at turnilo data (which IIRC is the last 90 days' requests) to effectively simulate a cache and ask questions about the relationship between cache size/age and hit/miss ratios and so on.
[which might be a useful KR for the forthcoming quarter]

MatthewVernon added a comment to T360617: docker-pkg error messages are confusing.

(if you try and build any other image, you still get the same error, which led me to assume my docker-pkg setup was faulty somehow - again, in hindsight, the error message does say it's unhappy with the ceph image, but the naïve user will observe the same bad request for localhost/v1.41/images/docker-registry.wikimedia.org/ and get led down the garden path.)

MatthewVernon added a comment to T357547: ☂️ Northward Datacentre Switchover (March 2024) .

Noting here for future reference - we found that thumbor was incorrectly using the global discovery record for swift, which meant that codfw-thumbor was trying to talk to eqiad-swift after codfw-swift was depooled, resulting in a rise in TempAuth errors (and 401s):

MatthewVernon added a comment to T359176: Long-titled archived files can get its path metadata truncated due to not having enough storage space, leading to orphan, non accesible files (was: Two files on commons have invalid UTF-8 characters in path metadata).

The issue is that the path is stored as varbinary(255) and path length is checked at upload to not exceed that. But then archiving adds archive and a date string to the start of the path, resulting in truncation.

Apropos theory 3, we do run the swift object expirer, but the relevant headers are not set (except for some specific use cases e.g. phonos). So I don't think it can be that.

I'd be surprised (and unhappy!) were swift randomly losing objects. If you have object names (ideally plus timestamps) from a recent example I could go grobbling in the logs to check.

Looking at this briefly (it's Saturday and the moment has passed), the request rate goes up somewhat (so looks unusual, but not at the level I would expect to cause an issue), but both frontend and backend network utilisation is significantly elevated, which makes me wonder if this was a lot of hits on an original rather than a thumb or similar.

[it's not immediately obvious to me what the extra work of cfssl gets us over sslcert]

MatthewVernon added a comment to T355914: Change default image thumbnail size.

I think the main issue is likely that we'll melt Thumbor if we just switch enwiki to 250, because 250 isn't a pregenerated size, and last time someone looked (T211661#8377883) only about 2% of requests were for that size. So I would assume that for the vast majority of images on enwiki we don't currently have a 250 thumb.

MatthewVernon added a comment to P55685 Extract storagekey for deleted objects.

The sed transform is space to underscore (a standard change for object name -> database entry) and ' to '' which quotes the ' character for mysql use (in a '-quoted string); the equivalent backslash-based approach would have been s/'/\\\'/g which is uglier.

Right, those are all too far ago to still in the recent logs. Today's, however, I can find, and swift has done what was asked of it - that file was uploaded and subsequently deleted (before further requests got 404, which you'd expect after a successful delete).
