#7872.
|
|
|
|
This removes a bunch of options from the task builder interface that are irrelevant to the new scheduler and were generally unused anyway. It also bumps the stack size of new scheduler tasks so that there's enough room to run rustc and changes the interface to `Thread` to not implicitly join threads on destruction, but instead require an explicit, and mandatory, call to `join`.
|
|
Main logic in ```Implement select() for new runtime pipes.```. The guts of the ```PortOne::try_recv()``` implementation are now split up across several functions, ```optimistic_check```, ```block_on```, and ```recv_ready```.
There is one weird FIXME I left open here, in the "implement select" commit -- an assertion I couldn't get to work in the receive path, on an invariant that for some reason doesn't hold with ```SharedPort```. Still investigating this.

|
Makes it more obvious what's going on
|
|
Seems to be around the minimum needed by rustc without split stacks

Before:
test bench_from_elem ... bench: 415 ns/iter (+/- 17)
test bench_set_memory ... bench: 85 ns/iter (+/- 4)
test bench_vec_repeat ... bench: 83 ns/iter (+/- 3)
After:
test bench_from_elem ... bench: 84 ns/iter (+/- 2)
test bench_set_memory ... bench: 84 ns/iter (+/- 5)
test bench_vec_repeat ... bench: 84 ns/iter (+/- 3)

available.

To be more specific:
`UPPERCASETYPE` was changed to `UppercaseType`
`type_new` was changed to `Type::new`
`type_function(value)` was changed to `value.method()`

A cleanup suggested on #7922.

Implements various missing tcp & udp methods.. Also fixes handling ipv4-mapped/compatible ipv6 addresses and addresses the XXX on `status_to_maybe_uv_error`.

This moves the raw struct layout of closures, vectors, boxes, and strings into a
new `unstable::raw` module. This is meant to be a centralized location to find
information for the layout of these values.
As safe method, `repr`, is provided to convert a rust value to its raw
representation. Unsafe methods to convert back are not provided because they are
rarely used and too numerous to write an implementation for each (not much of a
common pattern).

This is a cleanup pull request that does:
* removes `os::as_c_charp`
* moves `str::as_buf` and `str::as_c_str` into `StrSlice`
* converts some functions from `StrSlice::as_buf` to `StrSlice::as_c_str`
* renames `StrSlice::as_buf` to `StrSlice::as_imm_buf` (and adds `StrSlice::as_mut_buf` to match `vec.rs`.
* renames `UniqueStr::as_bytes_with_null_consume` to `UniqueStr::to_bytes`
* and other misc cleanups and minor optimizations

Some machinery for enabling #[bench] benchmarks in std and some examples showing how to write them.
|
|
These uses are assuming the strings are null terminated, so it
should be using `as_c_str` instead of `as_buf`

Place `pub` or `priv` on individual items instead.

Some notes about the commits.
Exit code propagation commits:
* ```Reimplement unwrap()``` has the same old code from ```arc::unwrap``` ported to use modern atomic types and finally (it's considerably nicer this way)
* ```Add try_unwrap()``` has some new slightly-tricky (but pretty simple) concurrency primitive code
* ```Add KillHandle``` and ```Add kill::Death``` are the bulk of the logic.
Task killing commits:
* ```Implement KillHandle::kill() and friends```, ```Do a task-killed check```, and ```Add BlockedTask``` implement the killing logic;
* ```Change the HOF context switchers``` turns said logic on
Linked failure commits:
* ```Replace *rust_task ptrs``` adapts the taskgroup code to work for both runtimes
* ```Enable taskgroup code``` does what it says on the tin.
