libtest: Improve error when missing `-Zunstable-options`

2023-05-24T16:18:20+00:00

"only accepted on the nightly compiler" is misleading when this *is* nightly.

Allow setting CFG_DISABLE_UNSTABLE_FEATURES to 0

2023-01-12T10:36:04+00:00

Two locations check whether this build-time environment variable is defined. Allowing it to be explicitly disabled with a "0" value is useful, especially for integrating with external build systems.

Fix `uninlined_format_args` in libtest

Create a hacky fail-fast mode that stops tests at the first failure

Add `IsTerminal` trait to determine if a descriptor or handle is a terminal

2022-10-14T23:35:38+00:00

The UNIX and WASI implementations use `isatty`. The Windows implementation uses the same logic the `atty` crate uses, including the hack needed to detect msys terminals. Implement this trait for `File` and for `Stdin`/`Stdout`/`Stderr` and their locked counterparts on all platforms. On UNIX and WASI, implement it for `BorrowedFd`/`OwnedFd`. On Windows, implement it for `BorrowedHandle`/`OwnedHandle`. Based on https://github.com/rust-lang/rust/pull/91121 Co-authored-by: Matt Wilkinson

Fix binary name in help message for test binaries

Use implicit capture syntax in format_args

2022-03-10T15:23:40+00:00

This updates the standard library's documentation to use the new syntax. The documentation is worthwhile to update as it should be more idiomatic (particularly for features like this, which are nice for users to get acquainted with). The general codebase is likely more hassle than benefit to update: it'll hurt git blame, and generally updates can be done by folks updating the code if (and when) that makes things more readable with the new format. A few places in the compiler and library code are updated (mostly just due to already having been done when this commit was first authored).

Use `optflag` for `--report-time`

2022-01-30T15:25:40+00:00

Essentially, what is described here: https://github.com/rust-lang/rust/issues/64888#issuecomment-1008047228 There is one difference. The comment proposes to add a `--report-time-color` option. This change instead uses libtest's existing `--color` option for that purpose.

Check `allow_unstable` before checking environment variables
