Hi Gilles,

Thank you for the very interesting read and generally for a job well done, as most of the users will never know that critical part of the infrastructure changed. :)

Where can we find more information about the thumb caching policy change that you mention in one of the posts?

Also, based on the bugs that you found in production and the solutions you implemented in order to prevent them, I was wondering if it would be feasible to reuse those in production: for instance, when the package is upgraded, try to regenerate all the thumbnails failed with the previous version; also, if a thumbnail that worked stops working, automatically notify the maintainers to look into the regression.

I wrote a blog series that just got picked up on the main Wikimedia blog about my work migrating Wikimedia wikis to Thumbor for media thumbnailing:

There's also a set of wiki pages with all the gory technical details of the setup: https://wikitech.wikimedia.org/wiki/Thumbor _______________________________________________ Wikitech-l mailing list Wikitech-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l
