Remove many RefCells from DocContext by camelid · Pull Request #82305 · rust-lang/rust

camelid · 2021-02-19T22:33:18Z

I left some of them so this change doesn't balloon in size and because
removing the RefCell in DocContext.resolver would require compiler
changes.

Thanks to @jyn514 for making this a lot easier with #82020!

Waiting for CI to pass and then will do perf run.

I left this one in because it seems the lifetimes get tricky because it's moved around.

Yeah, external_traits is a mess: https://rust-lang.zulipchat.com/#narrow/stream/266220-rustdoc/topic/Populating.20cache.20before.20intra-doc.20links

I left this one in because

It would require semi-significant changes

Ideally we're going to get rid of fake_def_ids at some point anyway (I think Joshua has an idea for that)

Well, "at some point" is probably pretty far off. But I'm fine with waiting for a follow-up PR.

Note to future readers: I was able to remove this one in #82382.

Might I say, LibEmbargoVisitor is one of the most interesting names I've seen in rust-lang/rust.

I've been eagerly watching the logs and the rustdoc testsuite just passed!

Finished benchmarking try commit (42c967a8b9046d57e776497be0724b4e1b1931c7): comparison url.

Benchmarking this pull request likely means that it is perf-sensitive, so we're automatically marking it as not fit for rolling up. Please note that if the perf results are neutral, you should likely undo the rollup=never given below by specifying rollup- to bors.

Importantly, though, if the results of this run are non-neutral do not roll this PR up -- it will mask other regressions or improvements in the roll up.

Fairly small improvements, but they're in the right direction, and it cleans up the code.
