2016-11-30Move small-copy optimization into <&[u8] as Read>Ruud van Asseldonk-2/+20
Based on the discussion in https://github.com/rust-lang/rust/pull/37573, it is likely better to keep this limited to std::io, instead of modifying a function which users expect to be a memcpy.
2016-11-30Move small-copy optimization into copy_from_sliceRuud van Asseldonk-15/+3
Ultimately copy_from_slice is being a bottleneck, not io::Cursor::read. It might be worthwhile to move the check here, so more places can benefit from it.
2016-11-30Add small-copy optimization for io::CursorRuud van Asseldonk-3/+15
During benchmarking, I found that one of my programs spent between 5 and 10 percent of the time doing memmoves. Ultimately I tracked these down to single-byte slices being copied with a memcopy in io::Cursor::read(). Doing a manual copy if only one byte is requested can speed things up significantly. For my program, this reduced the running time by 20%. Why special-case only a single byte, and not a "small" slice in general? I tried doing this for slices of at most 64 bytes and of at most 8 bytes. In both cases my test program was significantly slower.

2016-11-28std: Fix partial writes in LineWriterAlex Crichton-13/+86
Previously the `LineWriter` could successfully write some bytes but then fail to report that it has done so. Additionally, an erroneous flush after a successful write was permanently ignored. This commit fixes these two issues by (a) maintaining a `need_flush` flag to indicate whether a flush should be the first operation in `LineWriter::write` and (b) avoiding returning an error once some bytes have been successfully written. Closes #37807

Use displacement instead of initial bucket in HashMap code Use displacement instead of initial bucket in HashMap code. It makes the code a bit cleaner and also saves a few instructions (handy since it'll be using some to do some sort of adaptive behavior soon).

2016-11-21Auto merge of #37677 - jsen-:master, r=alexcrichtonbors-8/+26
libstd: support creation of anonymous pipe on WinXP/2K3 `PIPE_REJECT_REMOTE_CLIENTS` flag is not supported on Windows < VISTA, and every invocation of `anon_pipe` including attempts to pipe `std::process::Child`'s stdio fails. This PR should work around this issue by performing a runtime check of windows version and conditionally omitting this flag on "XP and friends". Getting the version should be probably moved out of the function `anon_pipe` itself (the OS version does not often change during runtime :) ), but: - I didn't find any precedent for this and assuming there's not much overhead (I hope windows does not perform any heuristics to find out it's own version, just fills couple of fields in the struct). - the code path is not especially performance sensitive anyway.
