This reverts commit 7cbd586ace46a8e8cebab660ebca3cfc049305d9.
This is causing a fail to build from source:
```
./lib/std/fmt.zig:492:17: error: cannot format optional without a specifier (i.e. {?} or {any})
@compileError("cannot format optional without a specifier (i.e. {?} or {any})");
^
./src/link/MachO/Atom.zig:544:26: note: called from here
log.debug(" RELA({s}) @ {x} => %{d} in object({d})", .{
^
```
I looked at the code to fix it but none of those args are optionals.

When lowering a struct type to an LLVM struct type, keep track of
whether there are any underaligned fields. If so, then make it a packed
llvm struct. This works because we already insert manual padding bytes
regardless.
We could unconditionally use an LLVM packed struct; the reason we bother
checking for underaligned fields is that it is a conservative choice, in
case LLVM handles packed structs less optimally. A future improvement
could simplify this code by unconditionally using packed LLVM structs
and then make sure measure perf is unaffected.

Fixes #11353
The renderer treats comments and doc comments differently since doc
comments are parsed into the Ast. This commit adds a check after getting
the text for the doc comment and trims whitespace at the end before
rendering.
The `a = 0,` in the test is here to avoid a ParseError while parsing the
test.

This library contains:
- The global constants as used by C code.
- An Insn struct that implements can generate all the BPF instructions.
- A simple BPF virtual machine implementation that can be used for
testing programs. This has complete code-coverage and has been
extensively fuzzed.

On certain systems (Solaris), resolving the scope id from an interface
name can only be done on AF_INET-domain sockets. While we're here,
simplify the test while we're here, since there's only one address.
Also note that the loopback interface name is not stable across OSs.
BSDs and Solaris use `lo0` whilst Linux uses `l0`.
|
|
Some systems (Solaris, OpenBSD, AIX) change their definitions of
sockaddr_storage to be larger than 128 bytes. This comment adds a new
constant in the `sockaddr` that defines the size for every system.
Fixes #9759

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.

Also move some usingnamespace test cases from compare_output to
behavior.

* 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.

The primary purpose of this change is to eliminate one usage of
`usingnamespace` in the standard library - specifically the usage for
errno values in `std.os.linux`.
This is accomplished by truncating the `E` prefix from error values, and
making errno a proper enum.
A similar strategy can be used to eliminate some other `usingnamespace`
sites in the std lib.

`msghdr` and `msghdr_const` definitions have been added back the way
they were in std.os. std.os.sendmsg has also been modified to accept a
msghdr_const again to ensure backwards-compatibility with this PR.
Underneath the hood, std.os.sendmsg will @ptrCast the provided
msghdr_const into a std.x.os.Socket.Message.
`sockaddr_storage` definitions have been added back the way they were in
std.os, except that it now simply aliases
std.x.os.Socket.Address.Native.Storage as all of
std.x.os.Socket.Address.Native.Storage's fields are equivalent to the
fields that were previously defined for std.x.os.bits.sockaddr_storage.
std.x.os.Socket.sendMessage now no longer is a stub that aliases
std.os.sendmsg, but instead calls and handles
errors from std.os.system.sendmsg directly.
Addresses feedback to urge backwards compatibility from @andrewrk.

Cross-platform versions of msghdr, sendmsg, recvmsg, linger, and iovec
were provided based on findings from glibc, musl, and Microsoft's
documentation.
Implemented initial Reactor interface for epoll (linux) which wraps
around I/O reactor subsystems such as epoll, kqueue, select, etc. across
different platforms. The Reactor interface allows for driving async I/O
in Zig applications.
A test was added for the Reactor interface to drive a TCP
client/listener socket pair.
A greatest-common-subset of possible socket initialization flags (close
socket on exec syscalls, initialize socket to be non-blocking) were
implemented.
A test was added for using sendmsg/recvmsg syscalls across different
platforms for a TCP client/listener socket pair.

Mainly I wanted Jakub's new macOS code for respecting stack size, since
we now depend on it for debug builds able to pass one of the test cases
for recursive comptime function calls with `@setEvalBranchQuota`.
The conflicts were all trivial.

Implement loading Winsock extensions.
Add missing Winsock extension GUID's.
Implement readVectorized() for POSIX sockets and
readVectorized() / writeVectorized() for Windows
sockets.
Inverse how mixins are used to implement platform-independent syscalls
for the std.x.os.Socket abstraction. This cleans up the API as suggested
by @komuw.

Add missing constants to ws2_32 such as SIO_BASE_HANDLE.
Made all declared constants in ws2_32 comptime_int, and fixed a few
broken constants (i.e. GUID's).
Fixed a few syscalls not having callconv(WINAPI) in ws2_32.
Fixed a typo in std.x.net.tcp.Client.
Removed unnecessary @alignCast's for socket addresses in
std.x.net.Socket.
Added a warning on using timeout methods for std.x.net.Socket.
Fixed compilation error spotted by CI in std.os that references
std.os.windows.ws2_32.SD_RECEIVE.
Renamed std.x.os.Socket.setOption()'s parameter `name: u32` to `code:
u32`.

Only allow SOCK_STREAM (std.x.net.tcp.Client) sockets to have wrappers
for std.io.Reader and std.io.Writer provided, instead of Socket's in
general.
|
|
Socket I/O methods such as read, readv, write, writev, send, recv,
sendmsg, recvmsg have been generalized to read(buf, flags), write(buf,
flags), readVectorized(vectors, flags), and writeVectorized(vectors,
flags). There is still some work left to be done abstracting both
readVectorized and writeVectorized properly across platforms, which is
work to be done in a future PR.
Support for setting the linger timeout of a socket, querying the remote
address of a socket, setting whether or not keep-alive messages are to
be sent through a connection-oriented socket periodically depending on
host operating system settings has been added.
`std.io.Reader` and `std.io.Writer` wrappers around `Socket` has been
implemented, which wrap around Socket.read(buf, flags) and
Socket.write(buf, flags). Both wrappers may be provided flags which are
passed to Socket.read / Socket.write accordingly.
Cross-platform support for `getpeername()` has been implemented.
Windows support for the new `std.x.os.Socket` has been implemented. To
accomplish this, a full refactor of `std.os.windows.ws2_32` has been
done to supply any missing definitions and constants based on
auto-generated Windows syscall bindings by @marler8997.
`std.x.net.TCP.Listener.setQuickACK` has been moved to
`std.x.net.TCP.Client.setQuickACK`.
Windows support for resolving the scope ID of an interface name
specified in an IPv6 address has been provided.
`sockaddr_storage` definitions have been provided for Windows, Linux,
and Darwin. `sockaddr_storage` is used to allocate space before any
socket addresses are queried via. calls such as accept(), getsockname(),
and getpeername().
Zig-friendly wrappers for GetQueuedCompletionStatusEx(), getpeername(),
SetConsoleCtrlHandler(), SetFileCompletionNotificationModes() syscalls
on Windows have been provided.
Socket.setOption() was provided to set the value of a socket option in
place of os.setsockopt. Socket.getOption() will be provided in a future
PR.
There is still further work to be done regarding querying socket option
values on Windows, which is to be done in a subsequent PR.

On OpenBSD, connecting to a newly-allocated port on an unspecified IPv4
host address causes EINVAL. This was found by @mikdusan when running TCP
tests on OpenBSD.
This commit fixes TCP tests on OpenBSD by having all tests that allocate
a new host-port pair to have the host IPv4/IPv6 address point to the
host's loopback adapter (on localhost).

protocols apart from TCP (i.e. UDP) operate solely over IP.

Use i32 instead of isize for os.timeval's for socket read/write
timeouts.
Add a comptime check to resolveScopeID to see if `IFNAMESIZE` is
available on the host. If it is not available, return an error
indicating that resolving the scope ID of a IPv6 address is not yet
supported on the host platform.

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.
