fs::copy() unix: set file mode early A convenience method like fs::copy() should try to prevent pitfalls a normal user doesn't think about. In case of an empty umask, setting the file mode early prevents temporarily world readable or even writeable files, because the default mode is 0o666. In case the target is a named pipe or special device node, setting the file mode can lead to unwanted side effects, like setting permissons on `/dev/stdout` or for root setting permissions on `/dev/null`. copy_file_range() returns EINVAL, if the destination is a FIFO/pipe or a device like "/dev/null", so fallback to io::copy, too.

2019-03-27Rollup merge of #59460 - xfix:include-id-in-thread-debug, r=AmanieuJosh Stone-1/+4
Include id in Thread's Debug implementation Since Rust 1.19.0, `id` is a stable method, so there is no reason to not include it in Debug implementation.
2019-03-27Rollup merge of #59451 - TimDiekmann:patch-1, r=sfacklerJosh Stone-1/+1
Add `Default` to `std::alloc::System` `System` is a unit struct, thus, it can be constructed without any additional information. Therefore `Default` is a noop. However, in generic code, a `T: Default` may happen as in ```rust #[derive(Default)] struct Foo<A> { allocator: A } ``` Does this need a feature gate? Should I also add `PartialEq/Eq/PartialOrd/Ord/Hash`?

2019-03-26Rollup merge of #59374 - faern:simplify-checked-duration-since, r=shepmasterMazdak Farrokhzad-37/+29
Simplify checked_duration_since This follows the same design as we updated to in #56490. Internally, all the system specific time implementations are checked, no panics. Then the panicking publicly exported API can just call the checked version of itself and make do with a single panic (`expect`) at the top. Since the internal sys implementations are now checked, this gets rid of the extra `if self >= &earlier` check in `checked_duration_since`. Except likely making the generated machine code simpler, it also reduces the algorithm from "Check panic condition -> call possibly panicking method" to just "call non panicking method". Added two test cases: * Edge case: Make sure `checked_duration_since` on two equal `Instant`s produce a zero duration, not a `None`. * Most common/intended usage: Make sure `later.checked_duration_since(earlier)`, returns an expected value.

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.
