2020-04-26Add Read/Write::can_read/write_vectoredSteven Fackler-0/+10
When working with an arbitrary reader or writer, code that uses vectored operations may end up being slower than code that copies into a single buffer when the underlying reader or writer doesn't actually support vectored operations. These new methods allow you to ask the reader or witer up front if vectored operations are efficiently supported. Currently, you have to use some heuristics to guess by e.g. checking if the read or write only accessed the first buffer. Hyper is one concrete example of a library that has to do this dynamically: https://github.com/hyperium/hyper/blob/0eaf304644a396895a4ce1f0146e596640bb666a/src/proto/h1/io.rs#L582-L594

2020-01-17Options IP_MULTICAST_TTL and IP_MULTICAST_LOOP are 1 byte on BSD and SolarisVita Batrla-18/+50
See ip(4P) man page: IP_MULTICAST_TTL Time to live for multicast datagrams. This option takes an unsigned character as an argument. Its value is the TTL that IP uses on outgoing multi- cast datagrams. The default is 1. IP_MULTICAST_LOOP Loopback for multicast datagrams. Normally multi- cast datagrams are delivered to members on the sending host (or sending zone). Setting the unsigned character argument to 0 causes the oppo- site behavior, meaning that when multiple zones are present, the datagrams are delivered to all zones except the sending zone. https://docs.oracle.com/cd/E88353_01/html/E37851/ip-4p.html https://man.openbsd.org/ip.4

2019-11-29Format libstd with rustfmtDavid Tolnay-113/+143
This commit applies rustfmt with rust-lang/rust's default settings to files in src/libstd *that are not involved in any currently open PR* to minimize merge conflicts. THe list of files involved in open PRs was determined by querying GitHub's GraphQL API with this script: https://gist.github.com/dtolnay/aa9c34993dc051a4f344d1b10e4487e8 With the list of files from the script in outstanding_files, the relevant commands were: $ find src/libstd -name '*.rs' \ | xargs rustfmt --edition=2018 --unstable-features --skip-children $ rg libstd outstanding_files | xargs git checkout -- Repeating this process several months apart should get us coverage of most of the rest of libstd. To confirm no funny business: $ git checkout $THIS_COMMIT^ $ git show --pretty= --name-only $THIS_COMMIT \ | xargs rustfmt --edition=2018 --unstable-features --skip-children $ git diff $THIS_COMMIT # there should be no difference

This renames `std::io::IoVec` to `std::io::IoSlice` and `std::io::IoVecMut` to `std::io::IoSliceMut`, and stabilizes `std::io::IoSlice`, `std::io::IoSliceMut`, `std::io::Read::read_vectored`, and `std::io::Write::write_vectored`. Closes #58452

This functionality has lived for a while in the tokio ecosystem, where it can improve performance by minimizing copies.

2018-12-06Refactor net::each_addr/lookup_host to forward error from resolveJethro Beekman-16/+58
2018-09-15Improve output if no_lookup_host_duplicates failsPhilip Munksgaard-2/+3
If the test fails, output the offending addresses and a helpful error message. Also slightly improve legibility of the preceding line that puts the addresses into a HashMap.
2018-01-16Only link res_init() on GNU/*nixRyan Cumming-21/+3
To workaround a bug in glibc <= 2.26 lookup_host() calls res_init() based on the glibc version detected at runtime. While this avoids calling res_init() on platforms where it's not required we will still end up linking against the symbol. This causes an issue on macOS where res_init() is implemented in a separate library (libresolv.9.dylib) from the main libc. While this is harmless for standalone programs it becomes a problem if Rust code is statically linked against another program. If the linked program doesn't already specify -lresolv it will cause the link to fail. This is captured in issue #46797 Fix this by hooking in to the glibc workaround in `cvt_gai` and only activating it for the "gnu" environment on Unix This should include all glibc platforms while excluding musl, windows-gnu, macOS, FreeBSD, etc. This has the side benefit of removing the #[cfg] in sys_common; only unix.rs has code related to the workaround now.

2017-10-05replace libc::res_init with res_init_if_glibc_before_2_26Jack O'Connor-4/+9
The previous workaround for gibc's res_init bug is not thread-safe on other implementations of libc, and it can cause crashes. Use a runtime check to make sure we only call res_init when we need to, which is also when it's safe. See https://github.com/rust-lang/rust/issues/43592.
2017-09-08Re-enable networking module fo rL4ReSebastian Humenda-4/+4
As suggested in the discussion of PR #43972, std should provide a uniform API to all platforms. Since there's no networking on L4Re, this now is a module in `sys::net` providing types and functions/methods returning an error for each action.
2017-08-07addrinfo hint in lookup_host() needs clean initialization on all platformsDanek Duvall-10/+2
Fixes #43649
2017-07-06Implement TcpStream::connect_timeoutSteven Fackler-0/+8
This breaks the "single syscall rule", but it's really annoying to hand write and is pretty foundational.
2017-06-20Add `Read::initializer`.Steven Fackler-4/+0
This is an API that allows types to indicate that they can be passed buffers of uninitialized memory which can improve performance.
2017-05-04Reload nameserver information on lookup failureJon Gjengset-3/+16
As discussed in #41570, UNIX systems often cache the contents of /etc/resolv.conf, which can cause lookup failures to persist even after a network connection becomes available. This patch modifies lookup_host to force a reload of the nameserver entries following a lookup failure. This is in line with what many C programs already do (see #41570 for details). On systems with nscd, this should not be necessary, but not all systems run nscd. Introduces an std linkage dependency on libresolv on macOS/iOS (which also makes it necessary to update run-make/tools.mk). Fixes #41570. Depends on rust-lang/libc#585.

2017-02-04libstd/net: Add `peek` APIs to UdpSocket and TcpStreamTyler Julian-11/+13
These methods enable socket reads without side-effects. That is, repeated calls to peek() return identical data. This is accomplished by providing the POSIX flag MSG_PEEK to the underlying socket read operations. This also moves the current implementation of recv_from out of the platform-independent sys_common and into respective sys/windows and sys/unix implementations. This allows for more platform-dependent implementations.
2016-11-01std: Move sys_common to libstd/sys_commonBrian Anderson-0/+633
Make the directory structure reflect the module structure. I've always found the existing structure confusing.
