rustc's startup has several layers, including: - `interface::run_compiler` passes a closure, `f`, to `run_in_thread_pool_with_globals`, which creates a thread pool, sets up session globals, and passes `f` to `create_compiler_and_run`. - `create_compiler_and_run` creates a `Session`, a `Compiler`, sets the source map, and calls `f`. rustdoc is a bit different. - `main_args` calls `main_options` via `run_in_thread_pool_with_globals`, which (again) creates a thread pool (hardcoded to a single thread!) and sets up session globals. - `main_options` has four different paths. - The second one calls `interface::run_compiler`, which redoes the `run_in_thread_pool_with_globals`! This is bad. - The fourth one calls `interface::create_compiler_and_run`, which is reasonable. - The first and third ones don't do anything of note involving the above functions, except for some symbol interning which requires session globals. In other words, rustdoc calls into `rustc_interface` at three different levels. It's a bit confused, and feels like code where functionality has been added by different people at different times without fully understanding how the globally accessible stuff is set up. This commit tidies things up. It removes the `run_in_thread_pool_with_globals` call in `main_args`, and adjust the four paths in `main_options` as follows. - `markdown::test` calls `test::test_main`, which provides its own parallelism and so doesn't need a thread pool. It had one small use of symbol interning, which required session globals, but the commit removes this. - `doctest::run` already calls `interface::run_compiler`, so it doesn't need further adjustment. - `markdown::render` is simple but needs session globals for interning (which can't easily be removed), so it's now wrapped in `create_session_globals_then`. - The fourth path now uses `interface::run_compiler`, which is equivalent to the old `run_in_thread_pool_with_globals` + `create_compiler_and_run` pairing.
There is no longer any need for them to be separate.
It has a single call site, and removing it slightly improves the confusing tangle of nested closures present at startup.
It has a single call site.
This avoids the need for a degenerate `Lrc::get_mut` call.
rust-lang#100892 implemented AsFd for the sys versions, rather than for the public types. Change the implementations to apply to the public types.
Small tweaks to changes made in a previous PR, unrelated to eager translation. Signed-off-by: David Wood <david.wood@huawei.com>
Eager translation will enable subdiagnostics to be translated multiple times with different arguments - this requires the ability to replace the value of one argument with a new value, which is better suited to a `HashMap` than the previous storage, a `Vec`. Signed-off-by: David Wood <david.wood@huawei.com>
`AddToDiagnostic::add_to_diagnostic_with` is similar to the previous `AddToDiagnostic::add_to_diagnostic` but takes a function that can be used by the caller to modify diagnostic messages originating from the subdiagnostic (such as performing translation eagerly). `add_to_diagnostic` now just calls `add_to_diagnostic_with` with an empty closure. Signed-off-by: David Wood <david.wood@huawei.com>
Add variant of `DiagnosticMessage` for eagerly translated messages (messages in the target language which don't need translated by the emitter during emission). Also adds `eager_subdiagnostic` function which is intended to be invoked by the diagnostic derive for subdiagnostic fields which are marked as needing eager translation. Signed-off-by: David Wood <david.wood@huawei.com>
Add support for `eager` argument to the `subdiagnostic` attribute which generates a call to `eager_subdiagnostic`. Signed-off-by: David Wood <david.wood@huawei.com>
Using eager translation, migrate the remaining repeated cycle stack diagnostic. Signed-off-by: David Wood <david.wood@huawei.com>
Diagnostic derives have previously had to take special care when ordering the generated code so that fields were not used after a move. This is unlikely for most fields because a field is either annotated with a subdiagnostic attribute and is thus likely a `Span` and copiable, or is a argument, in which case it is only used once by `set_arg` anyway. However, format strings for code in suggestions can result in fields being used after being moved if not ordered carefully. As a result, the derive currently puts `set_arg` calls last (just before emission), such as: ```rust let diag = { /* create diagnostic */ }; diag.span_suggestion_with_style( span, fluent::crate::slug, format!("{}", __binding_0), Applicability::Unknown, SuggestionStyle::ShowAlways ); /* + other subdiagnostic additions */ diag.set_arg("foo", __binding_0); /* + other `set_arg` calls */ diag.emit(); ``` For eager translation, this doesn't work, as the message being translated eagerly can assume that all arguments are available - so arguments _must_ be set first. Format strings for suggestion code are now separated into two parts - an initialization line that performs the formatting into a variable, and a usage in the subdiagnostic addition. By separating these parts, the initialization can happen before arguments are set, preserving the desired order so that code compiles, while still enabling arguments to be set before subdiagnostics are added. ```rust let diag = { /* create diagnostic */ }; let __code_0 = format!("{}", __binding_0); /* + other formatting */ diag.set_arg("foo", __binding_0); /* + other `set_arg` calls */ diag.span_suggestion_with_style( span, fluent::crate::slug, __code_0, Applicability::Unknown, SuggestionStyle::ShowAlways ); /* + other subdiagnostic additions */ diag.emit(); ``` Signed-off-by: David Wood <david.wood@huawei.com> Following the approach taken in earlier commits to separate formatting initialization from use in the subdiagnostic derive, simplify the diagnostic derive by removing the field-ordering logic that previously solved this problem.

Clean up rustdoc startup Startup is pretty hairy, in both rustdoc and rustc. The first commit here improves the rustdoc situation quite a bit. The remaining commits are smaller but also help. Best reviewed one commit at a time. r? ```@jyn514```
…r=fee1-dead Unify `tcx.constness` query and param env constness checks The checks that we do in the `constness` query seem inconsistent with the checks that we do to determine if an item's param-env is const, so I merged them into the `constness` query and call that from the `param_env` query. I'm not sure if this totally makes sense -- is there a case where `tcx.param_env()` would return a const param-env for an item whose `tcx.constness()` is `Constness::NotConst`? Because if not, it seems a bit dangerous that these two differ. Luckily, not many places actually use `tcx.constness()`, and the checks in `tcx.param_env()` seem stricter than the checks in `tcx.constness()` (at least for the types of items we type-check). Also, due to the way that `tcx.param_env()` is implemented, it _never_ used to return a const param-env for a item coming from a different crate, which also seems dangerous (though also probably not weaponizable currently, because we seldom actually compute the param-env for a non-local item).
