- Adds `illumos` to the `Target.Os.Tag` enum. A new function,
`isSolarish` has been added that returns true if the tag is either
Solaris or Illumos. This matches the naming convention found in Rust's
`libc` crate[1].
- Add the tag wherever `.solaris` is being checked against.
- Check for the C pre-processor macro `__illumos__` in CMake to set the
proper target tuple. Illumos distros patch their compilers to have
this in the "built-in" set (verified with `echo | cc -dM -E -`).
Alternatively you could check the output of `uname -o`.
Right now, both Solaris and Illumos import from `c/solaris.zig`. In the
future it may be worth putting the shared ABI bits in a base file, and
mixing that in with specific `c/solaris.zig`/`c/illumos.zig` files.

Insn.st() can be used with dynamic size just like Insn.stx(), which is
relevant in a code generation context.
using ImmOrReg caused an error as its fields were ordered differently than
Source.
Usage of FILE_RENAME_IGNORE_READONLY_ATTRIBUTE or
FILE_DISPOSITION_IGNORE_READONLY_ATTRIBUTE for posix semantics require
win10_rs5 instead of win10_rs1 necessary for posix semantics. Keep it as simple
as possible, since it is reasonable to expect users being able to update
win10_rs5 or use non-posix semantics instead.
Closes#17049.
This is a breaking change.
This commit applies the following rules to std.os.uefi:
* avoid redundant names in the namespace such as "protocol.FooProtocol"
* don't initialize struct field to undefined. do that at the
initialization site if you want that, or create a named constant that
sets all the fields to undefined.
* avoid the word "data", "info", "context", "state", "details", or
"config" in the type name, especially if a word from that category is
already in the type name.
* embrace tree structure
After following these rules, `usingnamespace` disappeared naturally.
This commit eliminates 26/53 (49%) instances of `usingnamespace` in the
standard library. All these uses were due to not understanding how
to properly use namespaces.
I did not test this commit. The standard library UEFI code is
experimental and pull requests have been accepted with minimal vetting.
Users of std.os.uefi will need to submit follow-up pull requests to fix
up whatever regressions this commit introduces, this time without
abusing namespaces (pun intended).
This matches how other filesystem functions were made to handle BAD_NETWORK_PATH/BAD_NETWORK_NAME in https://github.com/ziglang/zig/pull/16568. ReadLink was the odd one out, but that is no longer the case.
This fixes a few things:
- Previously, CreateSymbolicLink would always create a relative link if a `dir` was provided, but the relative-ness of a link should be determined by the target path, not the null-ness of the `dir`.
- Special handling is now done to symlink to 'rooted' paths correctly (they are treated as a relative link, which is different than how the xToPrefixedFileW functions treat them)
- ReadLink now correctly supports UNC paths via a new `ntToWin32Namespace` function which intends to be an analog of `RtlNtPathNameToDosPathName` (RtlNtPathNameToDosPathName is not used because it seems to heap allocate as it takes an RTL_UNICODE_STRING_BUFFER)
Previously, a relative path like `..` would:
- Attempt to be normalized (i.e. remove . and .. without any path resolution), but would error with TooManyParentDirs
- This would make wToPrefixedFileW run it through `RtlGetFullPathName_U` to do the necessary path resolution, but `RtlGetFullPathName_U` always resolves relative paths relative to the CWD
Instead, when TooManyParentDirs occurs, we now look up the path of the passed in `dir` (if it's non-null) and append the relative path to it before giving it to `RtlGetFullPathName_U`. If `dir` is null, then we just give it RtlGetFullPathName_U directly and let it resolve it relative to the CWD.
Closes#16779
* Replaces the exit assembly with the function from std.
* Reads the top-of-stack struct at program startup that can get information
like the pid.
* Changes the read and write functions to use the Pread and Pwrite syscalls
instead of the depreciated _READ and _WRITE
* Changes the openat function to use flags instead of perms.
Plan9 does not support perms when opening, just when creating.
* Adds an errstr function to read the errstr buf created by the kernel
Implements issue #6451.
This was needed to support allocation on Plan 9 and now other operating
systems like DOS can also use it.
It is a modified version of the WasmAllocator since wasm also uses a
sbrk-esque allocation system.
This commit also adds the necessary system bits for sbrk to work on plan 9.
After fixing some issues with inline assembly in the C backend, the std
cleanups have the side effect of making these functions compatible with
the backend, allowing it to be used on linux without linking libc.
The C++ version of this code used this logic, and it turns out it is able to find some setups that the current registry/Vs7 methods cannot.
For example, if only the "Build Tools for Visual Studio" are installed but not Visual Studio itself, then only the ISetupEnumInstances method seems to find it.
Follow up to #15657, fixes a regression caused by moving from the C++ version to the Zig version
Before this commit, there were three issues with the makePath implementation:
1. The component iteration did not 'collapse' consecutive path separators; instead, it would treat `a/b//c` as `a/b//c`, `a/b/`, `a/b`, and `a`.
2. Trailing path separators led to redundant `makeDir` calls, e.g. with the path `a/b/` (if `a` doesn't exist), it would try to create `a/b/`, then try `a/b`, then try `a`, then try `a/b`, and finally try `a/b/` again.
3. The iteration did not treat the root of a path specially, so on Windows it could attempt to make a directory with a path like `X:` for something like `X:\a\b\c` if the `X:\` drive doesn't exist. This didn't lead to any problems that I could find, but there's no reason to try to make a drive letter as a directory (or any other root path).
This commit fixes all three issues by introducing a ComponentIterator that is root-aware and handles both sequential path separators and trailing path separators and uses it in `Dir.makePath`. This reduces the number of `makeDir` calls for paths where (1) the root of the path doesn't exist, (2) there are consecutive path separators, or (3) there are trailing path separators
As an example, here are the makeDir calls that would have been made before this commit when calling `makePath` for a relative path like `a/b//c//` (where the full path needs to be created):
a/b//c//
a/b//c/
a/b//c
a/b/
a/b
a
a/b
a/b/
a/b//c
a/b//c/
a/b//c//
And after this commit:
a/b//c
a/b
a
a/b
a/b//c
When calling NtCreateFile with a UNC path, if either `\\server` or `\\server\share` are not found, then the statuses `BAD_NETWORK_PATH` or `BAD_NETWORK_NAME` are returned (respectively).
These statuses are not translated into `error.FileNotFound` because they convey more information than the typical FileNotFound error. For example, if you were trying to call `Dir.makePath` with an absolute UNC path like `\\MyServer\MyShare\a\b\c\d`, then knowing that `\\MyServer\MyShare` was not found allows for returning after trying to create the first directory instead of then trying to create `a\b\c`, `a\b`, etc. when it's already known that they will all fail in the same way.
