Now, all the tests that use `testWithAllSupportedPathTypes` will also run each test with both `/` and `\` as the path separator on Windows.
Also, removes the now-redundant "Dir.symLink with relative target that has a / path separator" since the same thing is now tested in the "Dir.readLink" test
InvalidHandle in OpenError is no longer a possible error on any platform. In the past it was able to be returned in `openOptionsFromFlagsWasi`, but the implementation was changed in 7680c5330cbc9141b9a5444e30c512b6068ab50d to make it no longer possible.
InvalidHandle in RealPathError was a holdover from before d5312d53a066092ba9efd687e25b29a87eb6290c, which made realpath a compile error on WASI. However, InvalidHandle was also a possible error in the FreeBSD fallback implementation added in 537624734c4db9e0cdbdc0ebce57375d17172a70. This commit changes the FreeBSD fallback implementation to return FileNotFound instead of InvalidHandle which matches how EBADF is handled in all the other `realpath` implementations (including the FreeBSD non-fallback implementation).
Closes#19084
Windows paths now use WTF-16 <-> WTF-8 conversion everywhere, which is lossless. Previously, conversion of ill-formed UTF-16 paths would either fail or invoke illegal behavior.
WASI paths must be valid UTF-8, and the relevant function calls have been updated to handle the possibility of failure due to paths not being encoded/encodable as valid UTF-8.

Encountered in a recent CI run on an aarch64-windows dev kit.
Pretty sure I disabled the virus scanner but it looks like it turned
itself back on with a Windows Update.
Rather than marking the new error code as unreachable in the places
where it is unexpected, this commit makes it return `error.Unexpected`.
* 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.
Because creation of a symlink can fail on Windows with an Access Denied
error (https://learn.microsoft.com/en-us/windows/security/threat-protection/security-policy-settings/create-symbolic-links)
any tests that need a symbolic link "skip" if they run into this problem.
This change factors out a "setupSymbolicLink()" routine to make this
clearer, a bit tighter, and easier to use in future tests.
I also collapsed the "symlink in parent directory" test into the existing
"Dir.readlink" test, because the latter uses the more comprehensive
testWithAllSupportedPathTypes wrapper.
The test runner uses "." in its output between the test module and the
test name, so quote the leading '.' in these test names to make them
easier to read.
std.fs.dir.makePath silently failed if one of the items in the path already exists. For example:
cwd.makePath("foo/bar/baz")
Silently failing is OK if "bar" is already a directory - this is the intended use of makePath (like mkdir -p). But if bar is a file then the subdirectory baz cannot be created - the end result is that makePath doesn't do anything which should be a detectable error because baz is never created.
The existing code had a TODO comment that did not specifically cover this error, but the solution for this silent failure also accomplishes the TODO task - the code now stats "foo" and returns an appropriate error. The new code also handles potential race condition if "bar" is deleted/permissions changed/etc in between the initial makeDir and statFile calls.
This issue already existed in master branch, however, the more
aggressive caching of builtin.zig in this branch made it happen more
often. I added doc comments to AtomicFile to explain when this problem
can occur.
For the compiler's use case, error.AccessDenied can be simply swallowed
because it means the destination file already exists and there is
nothing else to do besides proceed with the AtomicFile cleanup.
I never solved the mystery of why the log statements weren't printing
but those are temporary debugging instruments anyway, and I am already
too many yaks deep to whip out another razor.
closes#14978
In theory this is part of https://github.com/ziglang/zig/issues/18335, but these tests already pass since deleteTree does not depend on `OpenDirOptions.no_follow` behavior for these test cases:
- `deleteTree` always tries to delete the initial path as a file first, which will succeed on symlinks because `deleteFile` doesn't follow symlinks
- `deleteTree` when iterating a directory will get the type of symlinks as .sym_link, not as .directory (even if the symlink points to a directory), meaning it will never try to open a symlink as a directory.
The `no_follow` behavior happened to allow opening a file descriptor of a symlink itself on Windows, but that behavior may change in the future. Instead, we implement the opening of the symlink as a file descriptor manually (and per-platform) in the test case.
ctime is last file status/metadata change, not creation time. Note that this mistake was not made in the `File.metadata`/`File.Metadata` implementation, which allows getting the actual creation time.
Closes#18290
Requires an extra NtQueryInformationFile call when FILE_ATTRIBUTE_REPARSE_POINT is set to determine if it's actually a symlink or some other kind of reparse point (https://learn.microsoft.com/en-us/windows/win32/fileio/reparse-point-tags). This is something that `File.Metadata.kind` was already doing, so the same technique is used in `stat`.
Also, replace the std.os.windows.DeviceIoControl call in `metadata` with NtQueryInformationFile (NtQueryInformationFile is what gets called during kernel32.GetFileInformationByHandleEx with FileAttributeTagInfo, verified using NtTrace).
This reverts commit da94227f783ec3c92859c4713b80a668f1183f96, reversing
changes made to 8f943b3d33432a26b7e242c1181e4220ed400501.
I was against this change originally, but decided to approve it to keep
an open mind. After a year of trying it in practice, I firmly believe
that the previous way of doing it was better.
* 128-bit integer multiplication with overflow
* more instruction encodings used by std inline asm
* implement the `try_ptr` air instruction
* follow correct stack frame abi
* enable full panic handler
* enable stack traces
This reverts commit 0c99ba1eab63865592bb084feb271cd4e4b0357e, reversing
changes made to 5f92b070bf284f1493b1b5d433dd3adde2f46727.
This caused a CI failure when it landed in master branch due to a
128-bit `@byteSwap` in std.mem.
* Add missing period in Stack's description
This looks fine in the source, but looks bad when seen on the documentation website.
* Correct documentation for attachSegfaultHandler()
The description for attachSegfaultHandler() looks pretty bad without indicating that the stuff at the end is code
* Added missing 'the's in Queue.put's documentation
* Fixed several errors in Stack's documentation
`push()` and `pop()` were not styled as code
There was no period after `pop()`, which looks bad on the documentation.
* Fix multiple problems in base64.zig
Both "invalid"s in Base64.decoder were not capitalized.
Missing period in documentation of Base64DecoderWithIgnore.calcSizeUpperBound.
* Fix capitalization typos in bit_set.zig
In DynamicBitSetUnmanaged.deinit's and DynamicBitSet.deinit's documentation, "deinitializes" was uncapitalized.
* Fix typos in fifo.zig's documentation
Added a previously missing period to the end of the first line of LinearFifo.writableSlice's documentation.
Added missing periods to both lines of LinearFifo.pump's documentation.
* Fix typos in fmt.bufPrint's documentation
The starts of both lines were not capitalized.
* Fix minor documentation problems in fs/file.zig
Missing periods in documentation for Permissions.setReadOnly, PermissionsWindows.setReadOnly, MetadataUnix.created, MetadataLinux.created, and MetadataWindows.created.
* Fix a glaring typo in enums.zig
* Correct errors in fs.zig
* Fixed documentation problems in hash_map.zig
The added empty line in verify_context's documentation is needed, otherwise autodoc for some reason assumes that the list hasn't been terminated and continues reading off the rest of the documentation as if it were part of the second list item.
* Added lines between consecutive URLs in http.zig
Makes the documentation conform closer to what was intended.
* Fix wrongfully ended sentence in Uri.zig
* Handle wrongly entered comma in valgrind.zig.
* Add missing periods in wasm.zig's documentation
* Fix odd spacing in event/loop.zig
* Add missing period in http/Headers.zig
* Added missing period in io/limited_reader.zig
This isn't in the documentation due to what I guess is a limitation of autodoc, but it's clearly supposed to be. If it was, it would look pretty bad.
* Correct documentation in math/big/int.zig
* Correct formatting in math/big/rational.zig
* Create an actual link to ZIGNOR's paper.
* Fixed grammatical issues in sort/block.zig
This will not show up in the documentation currently.
* Fix typo in hash_map.zig
