This test has recently been failing on the bots, and I'm not entirely sure why.
I haven't been able to reproduce locally or on the bots, so I'm adding some
messages to help diagnose the problem hopefully.
The bitshifts were wrong in that they invoked undefined behavior and
only passed the lower byte of the presumed-to-be-32bit errno value.
Apparently all actually possible values for errno happen to be easily
under 256, so this didn't cause any actual problems.
This commit fixes the bitshifts, but doesn't generalize to errno types
that aren't 32bit.
Previously it output `partially moved` to eagerly. This updates it to be more
accurate and output `collaterally moved` for use of values that were invalidated
by moves out of different fields in the same struct.
Closes#15630.
Remove superfluous parentheses from the CTAGS_LOCATIONS expression.
Fixes the following error when executing `make TAGS.vi`:
/bin/sh: -c: line 0: syntax error near unexpected token `)'
Additionally, support zero-sized types.
Now there isn't a safe interface of `PartialVec` anymore, it's just a bare data structure with destructor that assumes you handled everything correctly before.
This PR begins the process of [runtime removal](https://github.com/rust-lang/rfcs/pull/230) by dismantling the `librustuv` crate and associated event loop.
The result is that, while `libgreen` can still be used for task scheduling purposes, it will no longer be feasible to use green-threaded I/O.
Removing the libuv-based event loop eases the transition away from the runtime system, which will be done incrementally.
In terms of visible API changes, this PR:
* Removes `std::io::signal`, which was never implemented on the native threading model.
* Removes the `iotest!` macro, which was previously used to run I/O tests on both green and native threading models.
* Removes the `green_start!` macro for starting an application with a `librustuv` event loop.
* Removes the `librustuv` crate itself.
It also removes the `libuv` and `gyp` submodules and adjusts the build system and copyright notices accordingly.
If you wish to continue using `librustuv` and green-threaded I/O, consider using [green-rs](https://github.com/alexcrichton/green-rs/), which provides its own I/O stack.
