When the unstable finterprint error was added, Rust was on fire, and we
needed a quick way for people to sort of understand what's going on,
follow the tracking issue, and leave some information without
overwhelming the issue tracker and focusing on getting their code
working.
This is what motivated the previous message. It called this a "known
issue", provided help on how to fix it, and only secondarily asked for a
bug report.
This is no longer true. These days incremental compilation is fairly
solid and these issues are supposed to be rare, we expect *none* of them
to exist (but obviously know that's not true). As such, it's time to
reword this message.
Recently someone mentioned how they didn't bother reporting this issue
because it said that it was a "known issue", and I only got awareness of
their problem because they complained about all the rustc-ice files
hanging around their directories. This is not at all what we want, we
want reports from people, ideally with a reproduction.
To get this, I reworded the error. It now explicitly asks for a
reproduction (and explaining what that means) and no longer calls it a
"known issue". It also does not link to the tracking issue anymore,
because I don't think this tracking issue is useful. It should probably
be closed.
I still mention the workaround, but explicitly call it a "workaround".
People should report a reproduction and only *then* use the workaround.
a more general version of https://github.com/rust-lang/rust/pull/146080.
after a bit of hacking in [`fluent.rs`](https://github.com/rust-lang/rust/blob/master/compiler/rustc_fluent_macro/src/fluent.rs), i discovered that i'm not the only one that is bad at following guidelines 😅. this pr lowercases the first letter of all the error messages in the codebase.
(i did not change things that are traditionally uppercased such as _MIR_, _ABI_ or _C_)
i think it's reasonable to run a `@bors try` so all the test suite is checked, as i cannot run some of the tests on my machine. i double checked (and replaced manually) all the old error messages, but better be safe than sorry.
in the future i will try to add a check in `x test tidy` that errors if an error message starts with an uppercase letter.
This makes it easier to open the messages file while developing on features.
