2019-03-21Auto merge of #58422 - LukasKalbertodt:seek-convenience, r=alexcrichtonbors-2/+134
Add provided methods `Seek::{stream_len, stream_position}` This adds two new, provided methods to the `io::Seek` trait: - `fn stream_len(&mut self) -> Result<u64>` - `fn stream_position(&mut self) -> Result<u64>` Both are added for convenience and to improve readability in user code. Reading `file.stream_len()` is much better than to manually seek two or three times. Similarly, `file.stream_position()` is much more clear than `file.seek(SeekFrom::Current(0))`. You can find prior discussions [in this internals thread](https://internals.rust-lang.org/t/pre-rfc-idea-extend-io-seek-with-convenience-methods-with-e-g-stream-len/9262). I think I addressed all concerns in that thread. I already wrote three RFCs to add a small new API to libstd but I noticed that many public changes to libstd happen without an RFC. So I figured I can try opening a PR directly without going through RFCs first. After all, we do have rfcbot here too. If you think this change is too big to merge without an RFC, I can still close this PR and write an RFC.
2019-03-21Auto merge of #58913 - Milack27:patch_buf_reader, r=joshtriplettbors-2/+45
Add new test case for possible bug in BufReader When reading a large chunk from a BufReader, if all the bytes from the buffer have been already consumed, the internal buffer is bypassed entirely. However, it is not invalidated, and it's possible to access its contents using the `seek_relative` method, because it tries to reuse the existing buffer.

Clarify distinction between floor() and trunc() `floor()` rounds towards `-INF`, `trunc()` rounds towards 0. This PR clarifies this in the examples.

2019-03-16Rollup merge of #59152 - smmalis37:range_contains, r=SimonSapinkennytm-1/+1
Stabilize Range*::contains. Closes https://github.com/rust-lang/rust/issues/32311. There's also a bit of rustfmt on range.rs thrown in for good measure (I forgot to turn off format-on-save in VSCode).
2019-03-16Rollup merge of #59147 - jethrogb:jb/time-tests, r=sfacklerkennytm-9/+2
Make std time tests more robust for platform differences Previously, `time::tests::since_epoch` and `time::tests::system_time_math` would fail if the platform represents a SystemTime as unix epoch + `u64` nanoseconds. r? @sfackler

2019-03-16Rollup merge of #58949 - jethrogb:jb/sgx-thread-id, r=joshtriplettkennytm-0/+6
SGX target: Expose thread id function in os module In order to call `std::os::fortanix_sgx::usercalls::send`, you need the thread id. This exposes it through another function in `std::os::fortanix_sgx`. I looked at how other platforms do this. On Windows and `cfg(unix)` you can get the OS handle from a `thread::JoinHandle`, but that's not sufficient, I need it for a `thread::Thread`. In the future, this functionality could be added to `thread::Thread` and this platform can follow suit. r? @joshtriplett
2019-03-16Rollup merge of #58901 - ebarnard:just-copying, r=sfacklerkennytm-2/+108
Change `std::fs::copy` to use `copyfile` on MacOS and iOS `copyfile` on MacOS is similar to `CopyFileEx` on Windows. It supports copying resource forks, extended attributes, and file ACLs, none of which are copied by the current generic unix implementation. The API is available from MacOS 10.7 and iOS 4.3 (and possibly earlier but I haven't checked). Closes #58895.
2019-03-16Rollup merge of #58855 - alexcrichton:wasm-multithreaded-alloc, r=fitzgenkennytm-15/+80
std: Spin for a global malloc lock on wasm32 There's lots of comments in the code, but the main gist of this commit is that the acquisition of the global malloc lock on the `wasm32-unknown-unknown` target when threads are enabled will not spin on contention rather than block.

std: Delete a by-definition spuriously failing test This commit deletes the `connect_timeout_unbound` test from the standard library which, unfortunately, is by definition eventually going to be a spuriously failing test. There's no way to reserve a port as unbound so we can rely on ecosystem testing for this feature for now. Closes #52590
2019-03-09Auto merge of #57882 - euclio:unused-doc-attributes, r=estebankbors-2/+2
overhaul unused doc comments lint This PR contains a number of improvements to the `unused_doc_comments` lint. - Extends the span to cover the entire comment when using sugared doc comments. - Triggers the lint for all unused doc comments on a node, instead of just the first one. - Triggers the lint on macro expansions, and provides a help note explaining that doc comments must be expanded by the macro. - Adds a label pointing at the node that cannot be documented. Furthermore, this PR fixes any instances in rustc where a macro expansion was erroneously documented.

Report the diagnostic on macro expansions, and add a label indicating why the comment is unused.

libstd: implement Error::source for io::Error
2019-03-08Rollup merge of #58893 - benaryorg:thread_local_example_join, r=alexcrichtonPietro Albini-1/+4
race condition in thread local storage example The example had a potential race condition that would still pass the test. If the thread which was supposed to modify it's own thread local was slower than the instruction to modify in the main thread, then the test would pass even in case of a failure. This is would be minor if the child thread was waited for since it check using an `assert_eq` for the same thing, but vice versa. However, if the `assert_eq` failed this would trigger a panic, which is not at all caught by the example since the thread is not waited on. Signed-off-by: benaryorg <binary@benary.org>
