2019-03-02Auto merge of #58216 - pitdicker:sqos_flags, r=alexcrichtonbors-8/+25
Set secure flags when opening a named pipe on Windows Fixes https://github.com/rust-lang/rust/issues/42036, see also the previous attempt in https://github.com/rust-lang/rust/pull/44556. Whether this is correct depends on if it is somehow possible to create a symlink to a named pipe, outside the named pipe filesystem (NPFS). But as far as I can tell that should be impossible. Also fixes that `security_qos_flags(SECURITY_ANONYMOUS)` does not set the `SECURITY_SQOS_PRESENT` flag, and the incorrect documentation about the default value of `security_qos_flags`.

Returning &'a mut [u8] was unsound, and we may as well just have them directly deref to their slices to make it easier to work with them.

2019-01-22Move Instant backing type to DurationAlex Berghage-22/+14
Per review comments, this commit switches out the backing type for Instant on windows to a Duration. Tests all pass, and the code's a lot simpler (plus it should be portable now, with the exception of the QueryPerformanceWhatever functions).
2019-01-22Simplify units in Duration/Instant math on WindowsAlex Berghage-42/+78
Right now we do unit conversions between PerfCounter measurements and nanoseconds for every add/sub we do between Durations and Instants on Windows machines. This leads to goofy behavior, like this snippet failing: ``` let now = Instant::now(); let offset = Duration::from_millis(5); assert_eq!((now + offset) - now, (now - now) + offset); ``` with precision problems like this: ``` thread 'main' panicked at 'assertion failed: `(left == right)` left: `4.999914ms`, right: `5ms`', src\main.rs:6:5 ``` To fix it, this changeset does the unit conversion once, when we measure the clock, and all the subsequent math in u64 nanoseconds. It also adds an exact associativity test to the `sys/time.rs` test suite to make sure we don't regress on this in the future.

2019-01-10std: Render large exit codes as hex on WindowsAlex Crichton-1/+10
On Windows process exit codes are never signals but rather always 32-bit integers. Most faults like segfaults and such end up having large integers used to represent them, like STATUS_ACCESS_VIOLATION being 0xC0000005. Currently, however, when an `ExitStatus` is printed this ends up getting rendered as 3221225477 which is somewhat more difficult to debug. This commit adds a branch in `Display for ExitStatus` on Windows which handles exit statuses where the high bit is set and prints those exit statuses as hex instead of with decimals. This will hopefully preserve the current display for small exit statuses (like `exit code: 22`), but assist in quickly debugging segfaults/access violations/etc. I've found at least that the hex codes are easier to search for than decimal. I wasn't able to find any official documentation saying that all system exit codes have the high bit set, but I figure it's a good enough heuristic for now.
2019-01-07std: Force `Instant::now()` to be monotonicAlex Crichton-0/+8
This commit is an attempt to force `Instant::now` to be monotonic through any means possible. We tried relying on OS/hardware/clock implementations, but those seem buggy enough that we can't rely on them in practice. This commit implements the same hammer Firefox recently implemented (noted in #56612) which is to just keep whatever the lastest `Instant::now()` return value was in memory, returning that instead of the OS looks like it's moving backwards. Closes #48514 Closes #49281 cc #51648 cc #56560 Closes #56612 Closes #56940
2019-01-05Rollup merge of #57314 - wiktorkuchta:master, r=Centrilkennytm-1/+1
Fix repeated word typos Inspired by #57295 (I skipped 'be be' because of it) and my [PR in another repo ](https://github.com/e-maxx-eng/e-maxx-eng/pull/389) Not a stupid `sed`, I actually tried to fix case by case.

Always run rustc in a thread cc @ishitatsuyuki @eddyb r? @pnkfelix [Previously](https://github.com/rust-lang/rust/pull/48575) we moved to only producing threads when absolutely necessary. Even before we opted to only create threads in some cases, which [is unsound](https://github.com/rust-lang/rust/pull/48575#issuecomment-380635967) due to the way we use thread local storage.

2018-12-14Auto merge of #56490 - faern:add-checked-add-to-instant, r=alexcrichtonbors-36/+23
Add checked_add method to Instant time type Appending functionality to the already opened topic of `checked_add` on time types over at #55940. Doing checked addition between an `Instant` and a `Duration` is important to reliably determine a future instant. We could use this in the `parking_lot` crate to compute an instant when in the future to wake a thread up without risking a panic.
