A common issue people run into when running compiletest is that filtering for files that don't exist is only a warning and not an error; running the whole test suite instead. See for example https://rust-lang.zulipchat.com/#narrow/stream/182449-t-compiler.2Fhelp/topic/Question.20about.20compiletest. This is especially bad when using `--bless`, which will modify all `.stderr` files. Change bootstrap to require valid filters instead of discarding invalid filters and continuing. Before: ``` Warning: Skipping "/home/jnelson/rust-lang/rust/src/test/rustdoc-ui/intra-doc/feature-gate-intra-doc-pointers.r": not a regular file or directory Check compiletest suite=rustdoc-ui mode=ui (x86_64-unknown-linux-gnu(x86_64-unknown-linux-gnu) -> x86_64-unknown-linux-gnu(x86_64-unknown-linux-gnu)) running 163 tests iiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii.......................... 100/163 ............................................................... test result: ok. 89 passed; 0 failed; 74 ignored; 0 measured; 0 filtered out; finished in 7.20s finished in 7.248 seconds Build completed successfully in 0:00:08 ``` After: ``` thread 'main' panicked at 'Invalid test suite filter "/home/jnelson/rust-lang/rust/src/test/rustdoc-ui/intra-doc/feature-gate-intra-doc-pointers.r": file or directory does not exist', src/bootstrap/util.rs:311: note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace Build completed unsuccessfully in 0:00:08 ```
This directory contains the source code of the rust project, including:
- The test suite
- The bootstrapping build system
- Various submodules for tools, like rustdoc, rls, etc.
For more information on how various parts of the compiler work, see the rustc dev guide.
