2019-12-20Rollup merge of #67442 - reitermarkus:dummy-variable, r=kennytmMazdak Farrokhzad-18/+9
Remove `SOCK_CLOEXEC` dummy variable on platforms that don't use it.
2019-12-20Rollup merge of #67219 - jsgf:command-argv0-debug, r=joshtriplettMazdak Farrokhzad-2/+6
Fix up Command Debug output when arg0 is specified. PR https://github.com/rust-lang/rust/pull/66512 added the ability to set argv[0] on Command. As a side effect, it changed the Debug output to print both the program and argv[0], which in practice results in stuttery output (`"echo" "echo" "foo"`). This PR reverts the behaviour to the the old one, so that the command is only printed once - unless arg0 has been set. In that case it emits `"[command]" "arg0" "arg1" ...`.

2019-12-19Rollup merge of #67270 - alexcrichton:write-more-line-writer, r=sfacklerMazdak Farrokhzad-1/+171
std: Implement `LineWriter::write_vectored` This commit implements the `write_vectored` method of the `LineWriter` type. First discovered in bytecodealliance/wasmtime#629 the `write_vectored` method of `Stdout` bottoms out here but only ends up writing the first buffer due to the default implementation of `write_vectored`. Like `BufWriter`, however, `LineWriter` can have a non-default implementation of `write_vectored` which tries to preserve the vectored-ness as much as possible. Namely we can have a vectored write for everything before the newline and everything after the newline if all the stars align well. Also like `BufWriter`, though, special care is taken to ensure that whenever bytes are written we're sure to signal success since that represents a "commit" of writing bytes.

2019-12-16Rollup merge of #67308 - dtolnay:fast_rebind, r=alexcrichtonMazdak Farrokhzad-15/+0
Delete flaky test net::tcp::tests::fast_rebind This test is unreliable for at least 3 users on two platforms: see #57509 and #51006. It was added 5 years ago in #22015. Do we know whether this is testing something important that would indicate a bug in our implementation, or if it's fine to remove? r? @sfackler @alexcrichton because this somewhat resembles #59018 Closes #57509. Closes #51006.

r=centril Revert stabilization of never type Fixes https://github.com/rust-lang/rust/issues/66757 I decided to keep the separate `never-type-fallback` feature gate, but tried to otherwise revert https://github.com/rust-lang/rust/pull/65355. Seemed pretty clean. ( cc @Centril, author of #65355, you may want to check this over briefly )

Require stable/unstable annotations for the constness of all stable fns with a const modifier r? @RalfJung @Centril Every `#[stable]` const fn now needs either a `#[rustc_const_unstable]` attribute or a `#[rustc_const_stable]` attribute. You can't silently stabilize the constness of a function anymore.
2019-12-14Auto merge of #67084 - Pagten:feature/print-msg-from-elf-entrypoint, r=Amanieubors-0/+30
SGX: Change ELF entrypoint This fixes [rust-sgx issue #148](https://github.com/fortanix/rust-sgx/issues/148). A new entry point is created for the ELF file generated by `rustc`, separate from the enclave entry point. When the ELF file is executed as a Linux binary, the error message below is written to stderr. > Error: This file is an SGX enclave which cannot be executed as a standard Linux binary. > See the installation guide at https://edp.fortanix.com/docs/installation/guide/ on how to use 'cargo run' or follow the steps at https://edp.fortanix.com/docs/tasks/deployment/ for manual deployment. When the ELF file is converted to an SGXS using `elf2sgxs`, the old entry point is still set as the enclave entry point. In a future pull request in the rust-sgx repository, `elf2sgxs` will be modified to remove the code in the ELF entry point, since this code is not needed in the enclave.

std:win: avoid WSA_FLAG_NO_INHERIT flag and don't use SetHandleInformation on UWP This flag is not supported on Windows 7 before SP1, and on windows server 2008 SP2. This breaks Socket creation & duplication. This was fixed in a previous PR. cc #26658 This PR: cc #60260 reuses this flag to support UWP, and makes an attempt to handle the potential error. This version still fails to create a socket, as the error returned by WSA on this case is WSAEINVAL (invalid argument). and not WSAEPROTOTYPE. MSDN page for WSASocketW (that states the platform support for WSA_FLAG_NO_HANDLE_INHERIT): https://docs.microsoft.com/en-us/windows/win32/api/winsock2/nf-winsock2-wsasocketw CC #26543 CC #26518
