Gilles added a comment to T172556: Images with embedded thumbnail whose orientation (rotation) is different than that of the main image render thumbnails wrong (smaller than they should be).

exiv2 seems to fare better and find that the image isn't rotated. Unfortunately exiv2's support of ICC profile is new (latest version, 0.26) and only lets us extract the profile, not check its name first. It's going to be difficult to use it as a drop-in replacement for exiftool right now. Thumbor uses pyexiv2 (wrapper for exiv2), which means we might be able to at least read the orientation with pyexiv2, and keep doing the rest with exiftool for now, until exiv2 supports all the features we need.

Stock Mediawiki, OS X and Chrome all seem to agree that this image isn't rotated. But exiftool, which Thumbor relies on, seems to think it should be rotated:

Gilles closed T153169: Grafana alerts for Navigation Timing and related as Resolved.

Sorry, we keep forgetting to acknowledge those in Icinga because the emails and IRC notifications are enough for us. This alert is well explained, it's the result of comparing to older data, in this case comparing to a period where our metric collection had issues. I wish there was a way to auto-acknowledge alerts in Icinga, because we really don't need that part, the notifications are enough for our need.

Something worth discussing here is whether the page queue *should* make visual progression worse. After all from the code's perspective, we already loading things low priority. But there's no option offered (out of the box) to load something low priority while being sure that it's not going to make the initial pageload worse in any way.

Gilles added a comment to T173804: Rotation parameters from EXIF fail in Mediawiki.

Unfortunately due to Mediawiki's filtering of EXIF before it reaches the image table, there's no way for us to compile a list of potentially affected files. Since this code has been running for 3 months now, purging all generated JPG thumbnails over that period is impractical. Which means that once the fix is deployed, affected files will have to be purged manually when encountered. Furthermore, once they fall out of Varnish cache eventually, they will fix themselves.
