Stream: t-compiler

Topic: pre-meeting triage 2019-07-18 #54818

This week the meeting will be run by yours truly. Starting the pre-triage early so that I can procrastinate from my procrastination leisurely.

nagisa (Jul 18 2019 at 12:16, on Zulip):

Forgone caching in cycles caused much overflow in trait solving #61960

Commented that I find it unlikely that anybody will work on this until the vacation spree is over. Especially since we raised the default recursion limit and it remediates this class of issues until an appropriate fix is made.

regression: rustdoc resolution changes #61560

Is weird, my kneejerk reaction is that this more of a rustdoc issue, than a rustc one. Need somebody to bisect where regression happened, I can do that.

nagisa (Jul 18 2019 at 12:23, on Zulip):

Compiler panic with generic-typed nested closures #59494

Unlikely to be looked at before the vacation spree is over.

nagisa (Jul 18 2019 at 12:27, on Zulip):

Unclear to me why Permit -> _ return types for improved diagnostics #56132 got marked as P-high.

nagisa (Jul 18 2019 at 12:33, on Zulip):

We have the following beta-nominated issues to look at:

Note that the two last issues are very closely related.

Furthermore these two isses are also nominated for backport to stable:

nagisa (Jul 18 2019 at 12:35, on Zulip):

It is likely that in the actual meeting I’ll dedicate most of the time for dealing with these nominations and we’ll do the rest if we end up having time.

nagisa (Jul 18 2019 at 12:36, on Zulip):

Mostly because it is the easy book-keeping that needs to be done sometime before the next train rollover that occurs in a month.

nagisa (Jul 18 2019 at 12:40, on Zulip):

Add a "diagnostic item" scheme for lints referring to libstd items #60966

Appears to be waiting for @oli to finalize their design. Removing I-nominated.

nagisa (Jul 18 2019 at 12:41, on Zulip):

Would be good if @oli did comment on the actual status of the PR.

nagisa (Jul 18 2019 at 12:42, on Zulip):

Turn HIR indexing into a query #59064

Has been visited before without notable changes since.

nagisa (Jul 18 2019 at 12:45, on Zulip):

1.30 -> 1.31 dylib late-binding regression with GNU binutils 2.28 or older. #61539

Removing nomination, as we discussed it briefly last week, albeit without conclusion.

nagisa (Jul 18 2019 at 12:51, on Zulip):

Encountered error Unimplemented selecting <...> during codegen #58375

Has a PR put up and approved for landing.

nagisa (Jul 18 2019 at 12:55, on Zulip):

ICE: Rust spins when referencing associated types in where clause #62430

@Esteban Küber managed to narrow this down to non-linear runtime, scheduling for a discussion at the actual meeting.

nagisa (Jul 18 2019 at 12:58, on Zulip):

Actually, since the cycle caching code is very related… referencing that issue in #62430 and un-nominating, as its status is essentially the same as for the other issues tracked by this meta-bug.

nagisa (Jul 18 2019 at 12:59, on Zulip):

Assigned to self to get an accurate bisection, though.

nagisa (Jul 18 2019 at 13:08, on Zulip):

ICE "no ImplicitCtxt stored in tls" in Servo on Windows and macOS #62717

Appears to have a solution already, so removed the nomination.
