Normalize opaques with late-bound vars again #113108

@compiler-errors compiler-errors commented Jun 27, 2023

We have a hack in the compiler where if an opaque has escaping late-bound vars, we skip revealing it even though we could reveal it from a technical perspective. First of all, this is weird, since we really should be revealing all opaques in Reveal::All mode. Second of all, it causes subtle bugs (linked below).

I attempted to fix this in #100980, which was unfortunately reverted due to perf regressions on codebases that used really deeply nested futures in some interesting ways. The worst of which was #103423, which caused the project to hang on build. Another one was #104842, which was just a slow-down, but not a hang. I took some time afterwards to investigate how to rework normalize_erasing_regions to take advantage of better caching, but that effort kinda fizzled out (#104133).

However, recently, I was made aware of more bugs whose root cause is not revealing opaques during codegen. That made me want to fix this again -- in the process, interestingly, I took the the minimized example from #103423 (comment), and it doesn't seem to hang any more...

Thinking about this harder, there have been some changes to the way we lower and typecheck async futures that may have reduced the pathologically large number of outlives obligations (see description of #103423) that we were encountering when normalizing opaques with bound vars the last time around:

... so given that I can see:

... and given that this PR:

I'm inclined to give this another shot at landing this. Best case, it just works -- worst case, we get more examples to study how we need to improve the compiler to make this work.

cc @rust-lang/types, I don't think this needs an FCP since this doesn't affect the type system in an observable way other than fixing potential ICEs -- I guess should be more of a T-compiler PR (but did r? for types because y'all have context). Just letting y'all know in case someone has strong opinions about this PR.

Maybe this is another case of this PR being impossible to land until #113065 is fixed, much like #112591

LeanderBB pushed a commit to LeanderBB/proton-api-rs that referenced this pull request Jul 9, 2023
Attempt to abstract sync and async requests by writing an abstraction
over the flow of data that encompasses a request. The requests fill out
a `RequestData` instance which then gets used as the source of future
transformations.

The login chain is a prime example of this. We define a series of steps
that are expressed as a series of sequences which will finally produce
the expected outcome.

The Session now produces a `Sequence` implementation which needs to be
driven by a client.

Unfortunately, due to lack of Async Trait support, the async
implementation is not as efficient as it could be. Attempt was made to
test the code on nightly, but ran into this bug
