* std.c: consolidate some definitions, making them share code. For
example, freebsd, dragonfly, and openbsd can all share the same
`pthread_mutex_t` definition.
* add type safety to std.c.O
- this caught a bug where mode flags were incorrectly passed as the
open flags.
* 3 fewer uses of usingnamespace keyword
* as per convention, remove purposeless field prefixes from struct field
names even if they have those prefixes in the corresponding C code.
* fix incorrect wasi libc Stat definition
* remove C definitions from incorrectly being in std.os.wasi
* make std.os.wasi definitions type safe
* go through wasi native APIs even when linking libc because the libc
APIs are problematic and wasteful
* don't expose WASI definitions in std.posix
* remove std.os.wasi.rights_t.ALL: this is a footgun. should it be all
future rights too? or only all current rights known? both are
the wrong answer.
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.
* 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`
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.
Do the alignment dance by ourselves whenever posix_memalign is not
available.
Don't try to use malloc as it has too many edge cases, figuring out
whether a block of memory is manually aligned by the mechanism above or
is directly coming from malloc becomes too hard to be valuable.
