@rust: Any ideas here?
Can someone point me at what this is trying to test, exactly? I'm not familiar with meson, and this is compiling Rust as a build system, where most users by far use Cargo instead -- so it's not exactly on the cowpath.
Here's a link to the test case. https://github.com/mesonbuild/meson/tree/master/test%20cases/rust/8%20many%20files
From #mesonbuild: <jpakkane> Ninja has a implementation limitation that any target that produces a dep file can have only one output file. That has multiple. At least in ye olden times rustc wrote a dep rule also for the depfile itself, which was wrong but I think they fixed it.
I guess ninja is complaining about having too many targets in manyfiles.d. > % cat manyfiles.d > manyfiles: ../test\ cases/rust/8\ many\ files/main.rs ../test\ cases/rust/8\ many\ files/foo.rs > > manyfiles.d: ../test\ cases/rust/8\ many\ files/main.rs ../test\ cases/rust/8\ many\ files/foo.rs > > ../test\ cases/rust/8\ many\ files/main.rs: > ../test\ cases/rust/8\ many\ files/foo.rs:
<jpakkane> The second line is flat out wrong. Ninja deletes all .d files immediately after reading so Ninja will always rebuild everything. This was reported to rustc upstream ages ago and IIRC they fixed it.
This appears to be an issue introduced with ninja-1.8.2-r1 (the kitware branch). The test passes with ninja-1.8.2 (vanilla upstream).
@brad.king: This commit seems to break the above meson test case. https://github.com/Kitware/ninja/commit/648da3f0ae757a0725640e63476370cc63e09169
Indeed, the commit includes a test case: https://github.com/Kitware/ninja/commit/648da3f0ae757a0725640e63476370cc63e09169#diff-43a4c476eaa3e085d18a2325d36994f9R273 specifically to cover rejection in the "depfile has multiple output paths" case. It corresponds to an existing test from upstream ninja: https://github.com/Kitware/ninja/commit/648da3f0ae757a0725640e63476370cc63e09169#diff-43a4c476eaa3e085d18a2325d36994f9L156 but is extended to the multiple rule case. That upstream ninja incorrectly tolerated this has allowed the bug in the depfile generation to go unnoticed. We may need to make it a warning for now instead.
I've updated Kitware's branch to convert the depfile error into a warning in this case. See new release at: https://github.com/Kitware/ninja/releases/tag/v1.8.2.g81279.kitware.dyndep-1.jobserver-1
