With bug 1678663 [1] now on central, web-platform-tests uses Python 3,
both locally under mach, and on Gecko CI. This matches upstream, where
the CI switched over a few weeks ago [2] and Google's CI which switched
at the end of last week.
For most users this change should be entirely transparent. It is however
relevant relevant to anyone writing a custom Python handler as part of
their tests:
* All python handlers must run under Python 3.6+ as well as Python 2.7 *
The requirement to maintain 2.7 compatibility is temporary to give all
wpt consumers a chance to migrate. The detailed timetable for the next
steps is as follows [3]:
* Jan 1st 2021, wpt consumers are expected to be using Python 3
* Feb 1st 2021, Python 2 no longer supported
Thanks for all the people who worked on this transition, and particular
thanks to Google/Igalia who took on the Sisyphean task of migrating all
the existing handler functions through the bytes/string changes without
altering the test behaviour. Unsurprisingly we have a lot of tests which
are very sensitive to the exact bytes sent over the wire, so this was a
big deal to get right.
As always please file bugs, or contact me on matrix [4] if you run into
any bugs as a result of these changes.
