Move some std tests to integration tests #135621

bjorn3 · 2025-01-17T11:08:02Z

Unit tests directly inside of standard library crates require a very fragile way of building that is hard to reproduce outside of bootstrap.

Follow up to #133859

cool. @bors r+
does this mean that the cfg(test) stuff on inherent impls and lang items etc can be removed?

Not yet. There are a whole bunch more tests that need to be handled. These are just some of the easier ones that are just testing the public api. There are also a lot of tests of private api's for which I don't have a good solution yet. Once all those tests are moved however we can indeed remove all cfg(test) on lang items and inherent impls.

I believe this failed in #135655

Thanks for the PR @bjorn3 ! We ran this PR on our internal CI for the SGX target and it fails with:

01:01:19    --> library/std/tests/sync/once_lock.rs:167:24
01:01:19     |
01:01:19 167 |                 crate::thread::yield_now();

01:01:19 167 +                 thread::yield_now();
01:01:19     |

I believe this is caused by the following line in the sync_once_cell_does_not_leak_partially_constructed_boxes test:

                #[cfg(target_env = "sgx")]
                crate::thread::yield_now();

and that it should be changed to:

                #[cfg(target_env = "sgx")]
                std::thread::yield_now();

could you please make this change? Thank you!

Just wanted to note, if it wasn't obvious why the error above happened, is that there are a bunch of set_var tests running in the same executable, which is obviously not thread-safe.

One suggestion is to move the set_var ones to a separate integration test so they don't interfere.

bjorn3 · 2025-01-23T14:29:49Z

SGX should be fixed now. And I moved the set_var tests to a separate integration test.

Awesome! :)
