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.
Currently, the new API will only be available on macOS with
the intention of adding more POSIX systems to it incrementally
(such as Linux, etc.).
Changes:
* add `posix_spawn` wrappers in a separate container in
`os/posix_spawn.zig`
* rewrite `ChildProcess.spawnPosix` using `posix_spawn` targeting macOS
as `ChildProcess.spawnMacos`
* introduce a `posix_spawn` specific `std.c.waitpid` wrapper which
does return an error in case the child process failed to exec - this
is required for any process that was spawned using `posix_spawn`
mechanism as, by definition, the errors returned by `posix_spawn`
routine cover only the `fork`-equivalent; `pre-exec()` and `exec()`
steps are covered by a catch-all error `ECHILD` returned by `waitpid`
on unsuccessful execution, e.g., no such file error, etc.
This adds a special CWD file descriptor, AT.FDCWD (-2), to refer to the
current working directory. The `*at(...)` functions look for this and
resolve relative paths against the stored CWD. Absolute paths are
dynamically matched against the stored Preopens.
"os.initPreopensWasi()" must be called before std.os functions will
resolve relative or absolute paths correctly. This is asserted at
runtime.
Support has been added for: `open`, `rename`, `mkdir`, `rmdir`, `chdir`,
`fchdir`, `link`, `symlink`, `unlink`, `readlink`, `fstatat`, `access`,
and `faccessat`.
This also includes limited support for `getcwd()` and `realpath()`.
These return an error if the CWD does not correspond to a Preopen with
an absolute path. They also do not currently expand symlinks.
* os/linux/io_uring: add recvmsg and sendmsg
* Use std.os.iovec and std.os.iovec_const
* Remove msg_ prefix in msghdr and msghdr_const in arm64 etc
* Strip msg_ prefix in msghdr and msghdr_const for linux arm-eabi
* Copy msghdr and msghdr_const from i386 to mips
* Add sockaddr to lib/std/os/linux/mips.zig
* Copy msghdr and msghdr_const from x86_64 to riscv64
As of 6249a24, align() is not allowed on packed struct fields
and as such the align(4) was removed from the first field of
EdidOverrideProtocolAttributes. The endgame here is packed struct
backed by explicit integers, in this case a u32, but until that
is implemented put the align(4) on the pointer to avoid breaking
someone's UEFI code in a hard to debug way.
This implements #10113 for the self-hosted compiler only. It removes the
ability to override alignment of packed struct fields, and removes the
ability to put pointers and arrays inside packed structs.
After this commit, nearly all the behavior tests pass for the stage2 llvm
backend that involve packed structs.
I didn't implement the compile errors or compile error tests yet. I'm
waiting until we have stage2 building itself and then I want to rework
the compile error test harness with inspiration from Vexu's arocc test
harness. At that point it should be a much nicer dev experience to work
on compile errors.
I found that after switching from my custom Guid parser to the one in std that it increased zigwin32 build times substantially (from 40 seconds to over 10 minutes). More information can be found in the benchmark PR I created here: https://github.com/ziglang/gotta-go-fast/pull/21 . This PR ports my GUID parser to std so all projects can leverage the faster comptime performance.
The size of a GUID is not platform-dependent, it's always a fixed number of bits. So I've updated guid to use fixed bit integer types rather than platform-dependent C integer types.
Beyond adding default zero-initialization, this commit changes undefined
initialization to zero, as some cases reserved the padding and on other
cases, I've found some systems act strange when giving uninit instead of
zero even when it shouldn't be an issue, one example being
FileProtocol.Open's attributes, which *should* be ignored when not
creating a file, but ended up giving an unrelated error.
I've seen having this be wrong break some cross-compilers, and it's
also how it is in other files so it's best to be consistent.
It's also just the actual casing of the file.
