Reading/Multimedia/Scrum notes/bawolff

Last update on: 2014-07-28

• Went through a significant portion of the back log of bugs in the MediaWiki/File management component.
  • Made a note of bugs that I think need looking into. Recategorized one's that were improperly categorized. Closed some bugs that were already fixed (14 less bugs in the component. Out of 282 bugs at the start)
• Fixed a bug in unit tests that decided to drop my user table (bugzilla:65654).

• Became acquainted with the situation surrounding the Fae thumbnail outage.
• Submitted a patch to make image renders for tiff files > 50 megapixels be no-ops instead of the current situation where they download the hundreds of MB big file only to throw away the download. I suspect this is a major part of the load issues on the image scalars since failed thumbnailing attempts have only a very short lived cache.

• Worked on adapting VipsScaler to work on tiff thumbnails so that we can scale larger files
• Locally this was successful, with the three biggest tiff files I could find on commons being scaled inside resource limits similar to Wikimedia's.

• Make unit tests work in PagedTiffHandler
• Add tests for my changes to PagedTiffHandler, VipsScaler
• Restructure some of the core media handler tests to avoid code duplication

• Small amount of code review/unit tests

• Did some code review
• Look into bugzilla:66143 (?embedplayer=yes broken)
• Added a unit test to my ogg metadata patch

• Read up around issues surounding resizing files in linear colour space (bugzilla:66337)
• Thumbnailing greyscale xcf files have output channels mixed up (bugzilla:66323)

• Adjust when pop up video viewer is used for large files
• Fun times with making TMH unit test do what I wanted it to do
• Minor fixes to Special:MIMESearch
  • Stop duplicate header output
  • Allow image/* type wild cards for the minor mime type

• Embedplayer=yes bug

• Checked to see what the state of the abandoned "sequencer" feature was, and if it still worked.
• Fixed warning about thumbnails of animated svg files (+unit tests)
