Extract existing constants to do with TCP socket options into a 'TCP'
namespace.
Export 'MSG' and 'TCP' from std.os.{linux, windows} into std.c.
Fix compile errors to do with std.x.os.Socket methods related to setting
TCP socket options.
Handle errors in the case that an interface could not be resolved in an
IPv6 address on Windows. Tested using Wine with the loopback interface
disabled.
Have all instantiations of std.x.os.Socket on Windows instantiate an
overlapped socket descriptor. Fixes the '1ms read timeout' test in
std.x.net.tcp.Client. The test would previously deadlock, as read
timeouts only apply to overlapped sockets.
Windows documentation by default recommends that most instantiations of
sockets on Windows be overlapped sockets (s.t. they may operate in both
blocking or nonblocking mode when operated with WSA* syscalls). Refer to
the documentation for WSASocketA for more info.
OpenBSD doesn't implement EVFILT_USER filter for kqueue(2), so we couldn't use that for event loop.
instead, use a EVFILT_TIMER filter with EV_ONESHOT (trigger only once) and delay 0sec (which trigger immediatly).
it fits the usage of EVFILT_USER which is only used to "wakeup" the kevent(2) call from userland.
I incorrectly assumed that __kernel_timespec was used when not linking
libc, however that is not the case. `std.os.timespec` is used both for
libc and non-libc cases. `__kernel_timespec` is a special struct that is
used only for io_uring.
Tests with no names are executed when using `zig test` regardless of the
`--test-filter` used. Non-named tests should be used when simply
importing unit tests from another file. This allows `zig test` to find
all the appropriate tests, even when using `--test-filter`.
* std lib tests are passing on x86_64-linux with and without -lc
* stage2 is building from source on x86_64-linux
* down to 38 remaining uses of `usingnamespace`
The main purpose of this branch is to explore avoiding the
`usingnamespace` feature of the zig language, specifically with regards
to `std.os` and related functionality.
If this experiment is successful, it will provide a data point on
whether or not it would be practical to entirely remove `usingnamespace`
from the language.
In this commit, `usingnamespace` has been completely eliminated from
the Linux x86_64 compilation path, aside from io_uring.
The behavior tests pass, however that's as far as this branch goes. It is
very breaking, and a lot more work is needed before it could be
considered mergeable. I wanted to put a pull requset up early so that
zig programmers have time to provide feedback.
This is progress towards closing #6600 since it clarifies where the
actual "owner" of each declaration is, and reduces the number of
different ways to import the same declarations.
One of the main organizational strategies used here is to do namespacing
with real namespaces (e.g. structs) rather than by having declarations
share a common prefix (the C strategy). It's no coincidence that
`usingnamespace` has similar semantics to `#include` and becomes much
less necessary when using proper namespaces.
This allows writing HEX files with `exe.installRaw`, where `exe` is a
`LibExeObjStep`. A HEX file will be written if the file extension is `.hex`
or `.ihex`, otherwise a binfile will be written. The output format can be
explicitly chosen with `exe.installRawWithFormat("filename", .hex);`
(or `.bin`)

* rework `build_options` to integrate with the FileSource abstraction
* support mapping as an arbitrarily named package
* support mapping to multiple different artifacts
* use hash of contents for options filename
We already have a LICENSE file that covers the Zig Standard Library. We
no longer need to remind everyone that the license is MIT in every single
file.
Previously this was introduced to clarify the situation for a fork of
Zig that made Zig's LICENSE file harder to find, and replaced it with
their own license that required annual payments to their company.
However that fork now appears to be dead. So there is no need to
reinforce the copyright notice in every single file.
