2017-10-08Rollup merge of #45083 - fhartwig:slice-read-to-end, r=blusskennytm-0/+8
Add read_to_end implementation to &[u8]'s Read impl The default impl for read_to_end does a bunch of bookkeeping that isn't necessary for slices and is about 4 times slower on my machine. The following benchmark takes about 30 ns before this change and about 7 ns after: ``` #[bench] fn bench_read_std(b: &mut Bencher) { let data = vec![0u8; 100]; let mut v = Vec::with_capacity(200); b.iter(|| { let mut s = data.as_slice(); v.clear(); s.read_to_end(&mut v).unwrap(); }); } ``` This solves the easy part of https://github.com/rust-lang/rust/issues/44819 (I think extending this to `Take<&[u8]> `would require specialization)

Fix TcpStream::local_addr docs example code The local address's port is not 8080 in this example, that's the remote peer address port. On my machine, the local address is different every time, so I've changed `assert_eq` to only test the IP address

2017-10-06Auto merge of #44734 - mchlrhw:wip/hashmap-entry-and-then, r=BurntSushibors-0/+35
Implement `and_modify` on `Entry` ## Motivation `Entry`s are useful for allowing access to existing values in a map while also allowing default values to be inserted for absent keys. The existing API is similar to that of `Option`, where `or` and `or_with` can be used if the option variant is `None`. The `Entry` API is, however, missing an equivalent of `Option`'s `and_then` method. If it were present it would be possible to modify an existing entry before calling `or_insert` without resorting to matching on the entry variant. Tracking issue: https://github.com/rust-lang/rust/issues/44733.
2017-10-06Auto merge of #44965 - oconnor663:res_init_glibc, r=dtolnaybors-4/+92
replace libc::res_init with res_init_if_glibc_before_2_26 The previous workaround for gibc's res_init bug is not thread-safe on other implementations of libc, and it can cause crashes. Use a runtime check to make sure we only call res_init when we need to, which is also when it's safe. See https://github.com/rust-lang/rust/issues/43592. ~This PR is returning an InvalidData IO error if the glibc version string fails to parse. We could also have treated that case as "not glibc", and gotten rid of the idea that these functions could return an error. (Though I'm not a huge fan of ignoring error returns from `res_init` in any case.) Do other folks agree with these design choices?~ I'm pretty new to hacking on libstd. Is there an easy way to build a toy rust program against my changes to test this, other than doing an entire `sudo make install` on my system? What's the usual workflow?

Remove mem::transmute used in Box<str> conversions Given that https://github.com/rust-lang/rust/pull/44877 is failing, I decided to make a separate PR. This is done with the same motivation: to avoid `mem::transmute`-ing non `#[repr(C)]` types.

2017-10-04Auto merge of #44979 - hinaria:master, r=dtolnaybors-0/+13
make `backtrace = false` compile for windows targets. when building for windows with `backtrace = false`, `libstd` fails to compile because some modules that use items from `sys_common::backtrace::*` are still included, even though those modules aren't used or referenced by anything. `sys_common::backtrace` doesn't exist when the backtrace feature is turned off. -- i've also added `#[cfg(feature = "backtrace")]` to various items that exist exclusively to support `mod backtrace` since the compilation would fail since they would be unused in a configuration with backtraces turned off.

Made `fs::copy` return the length of the main stream On Windows with the NTFS filesystem, `fs::copy` would return the sum of the lengths of all streams, which can be different from the length reported by `metadata` and thus confusing for users unaware of this NTFS peculiarity. This makes `fs::copy` return the same length `metadata` reports which is the value it used to return before PR #26751. Note that alternate streams are still copied; their length is just not included in the returned value. This change relies on the assumption that the stream with index 1 is always the main stream in the `CopyFileEx` callback. I could not find any official document confirming this but empirical testing has shown this to be true, regardless of whether the alternate stream is created before or after the main stream. Resolves #44532

2017-10-01Improve performance of spsc_queue and stream.Joshua Lockerman-99/+208
This commit makes two main changes. 1. It switches the spsc_queue node caching strategy from keeping a shared counter of the number of nodes in the cache to keeping a consumer only counter of the number of node eligible to be cached. 2. It separate the consumer and producers fields of spsc_queue and stream into a producer cache line and consumer cache line.

Add blanket TryFrom impl when From is implemented. Adds `impl<T, U> TryFrom<T> for U where U: From<T>`. Removes `impl<'a, T> TryFrom<&'a str> for T where T: FromStr` (originally added in #40281) due to overlapping impls caused by the new blanket impl. This removal is to be discussed further on the tracking issue for TryFrom. Refs #33417. /cc @sfackler, @scottmcm (thank you for the help!), and @aturon

Allow replacing HashMap entries This is an obvious API hole. At the moment the only way to retrieve an entry from a `HashMap` is to get an entry to it, remove it, and then insert a new entry. This PR allows entries to be replaced.
