Add wrap/unwrap return type in Option
I pretty much just copied over the code and tests for wrapping/unwrapping return types in `Result` and then did a bunch of find and replace changes.
I handled unwrapping statements returning `None` by just replacing `None` with the unit type, but I'm open to suggestions for more intuitive behavior here.
Update rustc-hash to version 2
This brings in the new optimized algorithm that was shown to have small performance benefits for rustc. I haven't run the rust-analyzer benchmarks.
See https://github.com/rust-lang/rustc-hash/pull/37.
feat: initial support for safe_kw in extern blocks
This PR adds initial support for `safe` keywords in external blocks.
## Changes
1. Parsing static declarations with `safe` kw and `unsafe` kw, as well as functions with `safe` kw in extern_blocks
2. Add `HAS_SAFE_KW ` to `FnFlags`
3. Handle `safe` kw in `is_fn_unsafe_to_call` query
4. Handle safe_kw in unsafe diagnostics
internal: Fix editorconfig glob
Had been testing Zed's editorconfig branch on r-a and noticed that something was odd with yaml files.
https://spec.editorconfig.org/#glob-expressions
> {s1,s2,s3}
> any of the strings given (separated by commas, can be nested) (But {s1} only matches {s1} literally.)
LSP says about Position::character
> If the character value is greater than the line length it defaults back to the line length.
but from_proto::offset() doesn't implement this.
A client might for example request code actions for a whole line by sending
Position::character=99999. I don't think there is ever a reason (besides laziness) why the
client can't specify the line length instead but I guess we should not crash but follow protocol.
Technically it should be a warning, not an error but warning is not shown by default so keep
it at error I guess.
Fixes#18240
internal: fix lldb-dap unconditionally calling rustc
Fixes https://github.com/rust-lang/rust-analyzer/issues/18318. I also took the opportunity to refactor how `discoverSourceFileMap` worked—it now returns a type instead of mutating a map in place.
I tested this change using the LLDB DAP extension. I needed to set `"lldb-dap.executable-path": "/Applications/Xcode.app/Contents/Developer/usr/bin/lldb-dap"` for everything to work, however, but once I did, was able to successfully debug a test.
Clamp Position::character to line length

Not sure how to update Cargo.lock (lib/README.md doesn't say how).

internal: Use local time when formatting logs
When debugging rust-analyzer and looking at logs, it's much easier to read when the timestamp is in the local timezone.

Emscripten: Xfail backtrace ui tests
It is possible to link libunwind and use the normal backtrace code, but it fails to symbolize stack traces. I investigated and could get the list of instruction pointers and symbol names, but I'm not sure how to use the dwarf info to map from instruction pointer to source location. In any case, fixing this is not a high priority.
See https://github.com/rust-lang/rust/issues/131738

Rename `can_coerce` to `may_coerce`, and then structurally resolve correctly in the probe
We need to structurally resolve the lhs and rhs of the coercion. Also, renaming the method so it's less ambiguous about what it's doing... the word "may" gives more clear signal that it has false positives imo.

Refactor some `core::fmt` macros
While looking at the macros in `core::fmt`, find that the macros are not well organized. So I created a patch to fix it.
[`core/src/fmt/num.rs`](https://github.com/rust-lang/rust/blob/master/library/core/src/fmt/num.rs)
* `impl_int!` and `impl_uint!` macro are **completly** same. It would be better to combine for readability
* `impl_int!` has a problem that the indenting is not uniform. It has unified into 4 spaces
* `debug` macro in `num` renamed to `impl_Debug`, And it was moved to a position close to the `impl_Display`.
[`core/src/fmt/float.rs`](https://github.com/rust-lang/rust/blob/master/library/core/src/fmt/float.rs)
[`core/src/fmt/nofloat.rs`](https://github.com/rust-lang/rust/blob/master/library/core/src/fmt/nofloat.rs)
* `floating` macro now receive multiple idents at once. It makes the code cleaner.
* Modified the panic message more clearly in fallback function of `cfg(no_fp_fmt_parse)`
Delay ambiguous intra-doc link resolution after `Cache` has been populated
Fixes https://github.com/rust-lang/rust/issues/130233.
I was getting nowhere with #130278. I took a wrong turn at some point and ended making way too many changes so instead I started again back from 0 and this time it worked out as expected.
