From 59c4dfe59d587f0f09746958bf9a16c271cc02a7 Mon Sep 17 00:00:00 2001 From: Zalathar Date: Wed, 1 Oct 2025 21:45:50 +1000 Subject: Forbid `//@ compile-flags: -Cincremental=` in tests Tests should not try to manually enable incremental compilation with `-Cincremental`, because that typically results in stray directories being created in the repository root. Instead, use the `//@ incremental` directive, which instructs compiletest to handle the details of passing `-Cincremental` with a fresh directory. --- .../compiletest-self-test/compile-flags-incremental.rs | 17 +++++++++++++++++ 1 file changed, 17 insertions(+) create mode 100644 tests/ui/compiletest-self-test/compile-flags-incremental.rs (limited to 'tests') diff --git a/tests/ui/compiletest-self-test/compile-flags-incremental.rs b/tests/ui/compiletest-self-test/compile-flags-incremental.rs new file mode 100644 index 00000000000..62a1ad84d8f --- /dev/null +++ b/tests/ui/compiletest-self-test/compile-flags-incremental.rs @@ -0,0 +1,17 @@ +//@ revisions: good bad bad-space +//@ check-pass + +//@[bad] compile-flags: -Cincremental=true +//@[bad] should-fail + +//@[bad-space] compile-flags: -C incremental=dir +//@[bad-space] should-fail + +fn main() {} + +// Tests should not try to manually enable incremental compilation with +// `-Cincremental`, because that typically results in stray directories being +// created in the repository root. +// +// Instead, use the `//@ incremental` directive, which instructs compiletest +// to handle the details of passing `-Cincremental` with a fresh directory. -- cgit 1.4.1-3-g733a5
