Fix lifetime on LocalInternedString::get function by Zoxc · Pull Request #59227 · rust-lang/rust

Zoxc · 2019-03-16T07:52:08Z

Re-interning here was intentional (to get rid of possible gensyms before checking).

Hence the interned call.

petrochenkov · 2019-03-16T08:06:17Z

Hm, shouldn't this keep working with non-static lifetime?
Also, a typo "f64f64" below.

No, the LocalInternedString is dropped in the first statement here.

I assume this is going to ruin the fn ident_str API in #58899 then.
Treating an attribute name as &str (including matching on it, calling contains) is a common operation, so returning Option<LocalInternedString> instead and mapping on it every time would be a serious usability hit.

Yeah. fn ident_str won't work. We should really use symbols for attribute names instead of comparing strings all the time.

True, the issue is just that a lot of existing code across rustc uses strings.

Addressed in #59256

eddyb · 2019-03-16T09:28:36Z

Please add a comment and maybe an ui-fulldeps test, to ensure this doesn't happen again?
And maybe self.string should be *const str instead.

I made this use unsafe code. That should prevent people from modifying this without reading comments.

☔ The latest upstream changes (presumably #58899) made this pull request unmergeable. Please resolve the merge conflicts.

nnethercote · 2019-03-20T21:54:05Z

Thanks for fixing this, @Zoxc. It's certainly an interesting lesson for me in the potential non-local effects of unsafe.

eddyb · 2019-03-21T11:50:51Z

IMO one should write *other rather than .deref().

eddyb · 2019-03-21T11:51:10Z

Actually, isn't AsRef<str> common practice in these sort of situations?

eddyb · 2019-03-21T11:52:03Z

There are too many of these, maybe a macro should be used (which can do *other == *self, I think).

eddyb · 2019-03-21T11:52:58Z

r=me with nits fixed (if at all, they're kind of inconsequential)

eddyb · 2019-03-22T19:07:49Z

I just realized this should probably be NonNull<str>.
