extra: Capture stdout/stderr of tests by default When tests fail, their stdout and stderr is printed as part of the summary, but this helps suppress failure messages from #[should_fail] tests and generally clean up the output of the test runner. 2014-02-12 10:25:09 -08:00			`// check-stdout`
Revise std::thread API to join by default This commit is part of a series that introduces a `std::thread` API to replace `std::task`. In the new API, `spawn` returns a `JoinGuard`, which by default will join the spawned thread when dropped. It can also be used to join explicitly at any time, returning the thread's result. Alternatively, the spawned thread can be explicitly detached (so no join takes place). As part of this change, Rust processes now terminate when the main thread exits, even if other detached threads are still running, moving Rust closer to standard threading models. This new behavior may break code that was relying on the previously implicit join-all. In addition to the above, the new thread API also offers some built-in support for building blocking abstractions in user space; see the module doc for details.

Give test and main tasks better names Tests now have the same name as the test that they're running (to allow for easier diagnosing of failure sources), and the main task is now specially named <main> instead of <unnamed>.

Rename fail! to panic! https://github.com/rust-lang/rfcs/pull/221 The current terminology of "task failure" often causes problems when writing or speaking about code. You often want to talk about the possibility of an operation that returns a Result "failing", but cannot because of the ambiguity with task failure. Instead, you have to speak of "the failing case" or "when the operation does not succeed" or other circumlocutions. Likewise, we use a "Failure" header in rustdoc to describe when operations may fail the task, but it would often be helpful to separate out a section describing the "Err-producing" case. We have been steadily moving away from task failure and toward Result as an error-handling mechanism, so we should optimize our terminology accordingly: Result-producing functions should be easy to describe. To update your code, rename any call to `fail!` to `panic!` instead. Assuming you have not created your own macro named `panic!`, this will work on UNIX based systems: grep -lZR 'fail!' . \| xargs -0 -l sed -i -e 's/fail!/panic!/g' You can of course also do this by hand.
