From 0079aadb158cf311228265c0f1e6bf1035578d0b Mon Sep 17 00:00:00 2001 From: Joshua Nelson Date: Sun, 24 Apr 2022 19:53:06 -0500 Subject: [PATCH] Fix running bootstrap tests on a fresh clone In #96303, I changed the tests not to manage submodules, with the main goal of avoiding a clone for llvm-project. Unfortunately, there are some tests which depend on submodules - I didn't notice locally because they were already checked out for me, and CI doesn't use submodule handling at all. Fresh clones, however, were impacted: ``` failures: ---- builder::tests::defaults::doc_default stdout ---- thread 'main' panicked at 'fs::read_dir(builder.src.join(&relative_path).join("redirects")) failed with No such file or directory (os error 2)', src/bootstrap/doc.rs:232:21 note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace ---- builder::tests::dist::dist_only_cross_host stdout ---- thread 'main' panicked at 'fs::read_to_string(&toml_file_name) failed with No such file or directory (os error 2)', src/bootstrap/lib.rs:1314:20 note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace ``` Try and get the best of both worlds by only checking out the submodules actually used in tests. --- src/bootstrap/builder/tests.rs | 9 +++++++++ 1 file changed, 9 insertions(+) diff --git a/src/bootstrap/builder/tests.rs b/src/bootstrap/builder/tests.rs index 3b6cd7564f08a..ebbce62763a97 100644 --- a/src/bootstrap/builder/tests.rs +++ b/src/bootstrap/builder/tests.rs @@ -7,7 +7,16 @@ fn configure(cmd: &str, host: &[&str], target: &[&str]) -> Config { // don't save toolstates config.save_toolstates = None; config.dry_run = true; + + // Ignore most submodules, since we don't need them for a dry run. + // But make sure to check out the `doc` and `rust-analyzer` submodules, since some steps need them + // just to know which commands to run. + let submodule_build = Build::new(Config::parse(&["check".to_owned()])); + let submodule_builder = Builder::new(&submodule_build); + submodule_builder.update_submodule(Path::new("src/doc/book")); + submodule_builder.update_submodule(Path::new("src/tools/rust-analyzer")); config.submodules = Some(false); + config.ninja_in_file = false; // try to avoid spurious failures in dist where we create/delete each others file // HACK: rather than pull in `tempdir`, use the one that cargo has conveniently created for us
