The system `stat` structure includes padding, and, on some
operating systems such as all BSDs, "spare" bytes at the end.
We can't reliably compare two `Stat` values if these are
uninitialized, while being later compared.
This is what was causing the `fstatat` test to fail on FreeBSD
since the update to LLVM 12. It was previously only passing by
accident.
There are some small problems here and there, mostly due to the pointers
having the lsb set and disrupting the fn alignment tests and the
`@FrameSize` implementation.
Address comments from @ifreund and @MasterQ32 to address unsafeness and
ergonomics of the `Address` API.
Rename the `TCP` namespace to `tcp` as it does not contain any
top-level fields.
Fix missing reference to `sockaddr` which was identified by @kprotty in
os/bits/linux/arm64.zig.
The `Socket` abstraction was refactored to only comprise of methods that
can be generically used/applied to all socket domains and protocols.
A more comprehensive IPv4/IPv6 module derived from @LemonBoy's earlier
work was implemented under `std.x.os.IPv4` and `std.x.os.IPv6`. Using
this module, one can then combine them together into a union for example
in order to optimize memory usage when dealing with socket addresses.
A `TCP.Client` and `TCP.Listener` abstraction is introduced that is one
layer over the `Socket` abstraction, which isolates methods that can
only be applied to a "client socket" and a "listening socket". All prior
tests from the `Socket` abstraction, which all previously operated
assuming the socket is operating via. TCP/IP, were moved. All TCP socket
options were also moved into the `TCP.Client` and `TCP.Listener`
abstractions respectively away from the `Socket` abstraction.
Some additional socket options from @LemonBoy's prior PR for Darwin were
also moved in (i.e. SIGNOPIPE).
liburing commit: 1bafb3ce5f
As stated in the liburing commit message, this fixes a regression,
reverting code that was added specutively to avoid a syscall in some
cases.
Beside the new order being consistent with the ThreadPool API and making
more sense, this shuffling allows to write the context argument type in
terms of the startFn arguments, reducing the use of anytype (eg. less
explicit casts when using comptime_int parameters, yay).
Sorry for the breakage.
Closes#8082
