This change allows to obtain an underlying invalid UTF-8 bytes without `FromUtf8Error` destruction. Such method may be useful for example in a library that attempts to save both valid and invalid UTF-8 strings in some struct and to be able to provide immutable access to it without destruction.
This no longer manifests on any versions of OSX that I could find.
We no longer need to track the tasks in these cases since these particular tasks have no outputs (except, potentially, errors...) and they always execute.
Because of its "magic" order-of-evaluation semantics, `move_val_init` must be lowered during MIR construction in order to work.
the `CollectItem` task no longer exists
It was discovered rust-lang#40264 that this backtrace pruning logic is a little too aggressive, so while we figure how out to handle rust-lang#40264 this commit backs out the changes to prune frames. Note that other cosmetic changes, such as better path printing and such remain.
Add `as_bytes()` for `FromUtf8Error`. This change allows to obtain an underlying invalid UTF-8 bytes without `FromUtf8Error` destruction. Such method may be useful for example in a library that attempts to save both valid and invalid UTF-8 strings in some struct and to be able to provide immutable access to it without destruction. Personally without this change I ended with `Result<String, (Vec<u8>, Utf8Error)`, which almost copies the functionality of `FromUtf8Error`, but allows immutable view access.
Improve Process::spawn with piped stdio on Redox - Adds `dup2`, and uses it for stdio piping - Removes `O_CLOEXEC` from piped stdio, as `dup` on Redox does not disable O_CLOEXEC
…xcrichton bootstrap: Don't workaround uname -m on Darwin This no longer manifests on any versions of OSX that I could find. How far back is Rust officially supported? I can try to get copies to test when this behaviour changed. (Fun fact, at a minimum the comment already lies, since the flag is `-m` :))

Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @arielb1 (or someone else) soon. If any changes to this PR are deemed necessary, please add them as extra commits. This ensures that the reviewer can see what has changed since they last reviewed the code. Due to the way GitHub handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed. Large or tricky changes may require several passes of review and changes. Please see the contribution instructions for more information. |
