Avoid writes without any data by advancing the buffers first. This matches the documented behaviour of `Write::write_all_vectored` and is analogous to what happens in `Write::write_all`. 2020-07-26T05:50:51+00:00 bors bors@rust-lang.org 2020-07-26T05:50:51+00:00 urn:sha1:461707c5a119cc33c5d7df585ddb6cbec4a081bf Remove trait LengthAtMost32 This is a continuation of https://github.com/rust-lang/rust/pull/74026 preserving the original burrbull's commit.

This documents the `ref` keyword with two examples, one failing to compile because the `ref` keyword is missing, and the same example fixed with the keyword inserted in the correct place. It also explains (very *very* rapidly) the differences between `&` and `ref`. I put a link to the best place I could find in the Reference but there may be something better that I didn't find. 2020-07-24T22:00:23+00:00 bors bors@rust-lang.org 2020-07-24T22:00:23+00:00 urn:sha1:5ef299eb9805b4c86b227b718b39084e8bf24454 Miri: use extern fn to expose interpreter operations to program; fix leak checker on Windows This PR realizes an idea that @oli-obk has been suggesting for a while: to use Miri-specific `extern` functions to provide some extra capabilities to the program. Initially, we have two of these methods, which libstd itself needs: * `miri_start_panic`, which replaces the intrinsic of the same name (mostly for consistency, to avoid having multiple mechanisms for Miri-specific functionality). * `miri_static_root`, which adds an allocation to a list of static "roots" that Miri considers as not having leaked (including all memory reachable through them). This is needed for https://github.com/rust-lang/miri/issues/1302. We use `extern` functions instead of intrinsics for this so that user code can more easily call these Miri hoolks -- e.g. `miri_static_root` should be useful for https://github.com/rust-lang/miri/issues/1318. The Miri side of this is at https://github.com/rust-lang/miri/pull/1485. r? @oli-obk 2020-07-24T17:33:52+00:00 Alexis Bourget alexis.bourget@gmail.com 2020-07-24T17:33:52+00:00 urn:sha1:6af60d3e2434490ed0e4a4fee40435c989753a0b 2020-07-24T17:06:26+00:00 Alexis Bourget alexis.bourget@gmail.com 2020-07-24T17:06:26+00:00 urn:sha1:79f052bd4fa7f695a96515c44c5a72e75cf782ee 2020-07-24T17:01:28+00:00 Manish Goregaokar manishsmail@gmail.com 2020-07-24T17:01:28+00:00 urn:sha1:dfedb84462ed2281877ec10253e659155213e7c8 revise RwLock for HermitCore - current version is derived from the wasm implementation - increasing the readability of `Condvar` - simplify the interface to the libos
