Re: [webkit-dev] Huge improvement in Safari results on wpt.fyi

2018-10-12 Thread Philip Jägenstedt 
Hi Dean,

On the run of Safari that was used for this report, the infrastructure
test for ahem was actually passing:
https://wpt.fyi/results/infrastructure/assumptions?sha=67152fdecd&product=chrome[stable]&product=edge[stable]&product=firefox[stable]&product=safari[experimental]

Are you sure that Ahem is the explanation for the failures, do you
have a test that you think is actually passing and the wpt.fyi results
are wrong? Clearly, having screenshots would make it easier to
understand a situation like this, and it's something we've discussed a
bit today:
https://github.com/web-platform-tests/wpt.fyi/issues/57

I don't think we should change a bunch of tests, it's useful to be
able to depend on *some* system font existing across the board, and
Ahem is it. We already need root access in our CI systems because of
/etc/hosts, so just putting Ahem in /Library/Fonts as part of the
setup is fine.

I'd also like to know when this change happened, because in
https://github.com/foolip/wpt/pull/5 I had to work around it for Azure
Pipelines, which has macOS 10.13.6, while all the other CI systems I
tried worked with the code as-is. They are all running the same
version of STP. (This PR is still just me experimenting, but the goal
is to get Safari coverage for PRs pretty soon.)

See https://github.com/web-platform-tests/wpt/issues/9105 about this.

I don't have a strong opinion here, but: a) it certainly seems
annoying to flush layout and avoid triggering any layout invalidation
bugs; b) we have plenty of other (manual 🙁) tests for the font
matching algorithm (and parts of that obviously do need to use system
installed fonts).

As an aside: when did user installed fonts stop being allowed by
default? r226172 states nothing is using the SPI yet (though did it
already default to No? in which case it has been disallowed by default
since r225641). wpt.fyi seems to have Ahem being installed okay for
STP but not stable, based on infrastructure/assumptions/ahem.html, and
all that does it copy the font to ~/Library/Fonts, which confuses me!

I'd like to suggest to discuss this on the above linked WPT issue; the
CSS WG are far from the only stakeholder here (there are plenty of
reftests elsewhere in WPT!).
