@jyn514 Since you were the one who approved this option, is there anything we need to check beforehand or is it ready to go through FCP?

Also, cc @rust-lang/rustdoc since it's a stabilization PR.

I don't want to be involved with this decision.

Also, cc rust-lang/rustdoc since it's a stabilization PR.

This is not how stabilization PRs work. There should be an FCP with checkboxes and a stabilization report.

I wanted to get some insight from you before starting FCP (as I mentioned in my comment) but it's fine.

@Swatinem: Can you write a stabilization report before we move any further please?

Can you write a stabilization report before we move any further please?

I wrote that up here: #84674 (comment)

While doing so I realized that --test-run-directory is just an implementation detail of the cargo doctest-in-workspace flag that itself is fixing an inconsistency between doctests and other types of tests, and I would want to eventually make that the default in the future.

I’m not sure if its possible to fix that behavior in stable cargo without having to first stabilize the rustdoc flag?

@GuillaumeGomez

Maybe bring it up to the cargo team first to ensure they will agree with it first before we start anything then.

The cargo team seems to be on board for this change based on this comment. I copy the stabilization report here from this comment:

Request for Stabilization

I opened #103682 with the aim to stabilize this rustdoc flag, primarily to facilitate the cargo doctest-in-workspace flag, and to eventually making it the default.

Summary

The --test-run-directory flag in combination with --test allows specifying an explicit directory in which rustdoc will run the compiled doctests. The default, without this explicit flag, is to run the resulting doctest binaries in the same current working directory as rustdoc itself.

This flag is primarily the building block for the doctest-in-workspace cargo flag (See rust-lang/cargo#9427).

With that flag, doctests are handled consistently to unit- and integration tests: They will be compiled relative to the cargo workspace root, but they are run in the crate directory.

Documentation

The flag is currently not documented as part of the unstable rustdoc features.

Tests

Unresolved questions

  • Similar flags that allow hooking into or observing the side effects of rustdoc test compilation, such as --run-tool or --persist-doctests are not stable yet, and there does not seem to be a push to stabilization either.
  • The usefulness of this flag when invoking rustdoc manually might be limited. But it is a requirement for the cargo doctest-in-workspace flag.
  • ☝🏻 Is there maybe a better alternative to solve the compile/run directory inconsistency that exists in cargo workspaces today?

I've become an alumni since the FCP started, so someone else can check my box. For what it's worth, the stabilization reason seems compelling enough to me.

Can you add documentation for this option into the rustdoc book please? (in src/doc/rustdoc)

@Swatinem

I added some more documentation for the new flag, as well as another file!() assertion to the test. I hope that is stable across all the test platforms. I will check Windows later today.

This comment has been minimized.

@Swatinem

Well, CI is already unhappy about asserting file!() output, so I removed that.

@GuillaumeGomez Docs for this option were added. Is there another blocker for moving this along?

Upstream changes:

Version 1.70.0 (2023-06-01)
==========================

Language
--------
- [Relax ordering rules for `asm!` operands]
  (rust-lang/rust#105798)
- [Properly allow macro expanded `format_args` invocations to uses
  captures] (rust-lang/rust#106505)
- [Lint ambiguous glob re-exports]
  (rust-lang/rust#107880)
- [Perform const and unsafe checking for expressions in `let _ =
  expr` position.]
  (rust-lang/rust#102256)

Compiler
--------
- [Extend -Cdebuginfo with new options and named aliases]
  (rust-lang/rust#109808)
  This provides a smaller version of debuginfo for cases that only
  need line number information (`-Cdebuginfo=line-tables-only`),
  which may eventually become the default for `-Cdebuginfo=1`.
- [Make `unused_allocation` lint against `Box::new` too]
  (rust-lang/rust#104363)
- [Detect uninhabited types early in const eval]
  (rust-lang/rust#109435)
- [Switch to LLD as default linker for {arm,thumb}v4t-none-eabi]
  (rust-lang/rust#109721)
- [Add tier 3 target `loongarch64-unknown-linux-gnu`]
  (rust-lang/rust#96971)
- [Add tier 3 target for `i586-pc-nto-qnx700` (QNX Neutrino RTOS,
  version 7.0)] (rust-lang/rust#109173),
- [Insert alignment checks for pointer dereferences as debug assertions]
  (rust-lang/rust#98112)
  This catches undefined behavior at runtime, and may cause existing
  code to fail.

Cargo
-----

- [Add `CARGO_PKG_README`]
  (rust-lang/cargo#11645)
- [Make `sparse` the default protocol for crates.io]
  (rust-lang/cargo#11791)
- [Accurately show status when downgrading dependencies]
  (rust-lang/cargo#11839)
- [Use registry.default for login/logout]
  (rust-lang/cargo#11949)
- [Stabilize `cargo logout`]
  (rust-lang/cargo#11950)

Misc
----

- [Stabilize rustdoc `--test-run-directory`]
  (rust-lang/rust#103682)

Compatibility Notes
-------------------

- [Prevent stable `libtest` from supporting `-Zunstable-options`]
  (rust-lang/rust#109044)
- [Perform const and unsafe checking for expressions in `let _ =
  expr` position.]
  (rust-lang/rust#102256)
- [WebAssembly targets enable `sign-ext` and `mutable-globals`
  features in codegen]
  (rust-lang/rust#109807)
  This may cause incompatibility with older execution environments.
- [Insert alignment checks for pointer dereferences as debug assertions]
  (rust-lang/rust#98112)
  This catches undefined behavior at runtime, and may cause existing
  code to fail.

Internal Changes
----------------

These changes do not affect any public interfaces of Rust, but they represent
significant improvements to the performance or internals of rustc and related
tools.

- [Upgrade to LLVM 16]
  (rust-lang/rust#109474)
- [Use SipHash-1-3 instead of SipHash-2-4 for StableHasher]
  (rust-lang/rust#107925)
