This reverts commit da94227f78, reversing
changes made to 8f943b3d33.
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 0c99ba1eab, reversing
changes made to 5f92b070bf.
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
* fs/test.zig: use arena allocator more consistently
* fs/test.zig: remove unnecessary type information
Zig can (now?) implicitly cast a `&.{ "foo"}` when passed to
`fs.path.join()`, so the `[_][]const u8` is unnecessary.
* fs/test.zig: Use fs.path.join() for longer paths
Replace long path constructions (that use several "++ path_sep ++")
with a single call to `fs.path.join`. Seems more readable to me.
* fs/test.zig: fmt
- 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.

`statFile` now only uses `os.fstatatWasi` when not linking libc, matching the pattern used throughout other `Dir` functions. This fixes the compilation error: `error: struct 'c.wasi.Stat' has no member named 'fromFilestat'` (which the added test would have failed with)
In theory, localhost could be mapped to a different address via the LMHOSTS file, so using 127.0.0.1 should remove that potential wrinkle and allow the drive-absolute -> UNC transformation to work on any(?) setup.
Also print the error name to ensure it gets printed in CI (aarch64-windows ReleaseSmall seemed not to print the error in the last intermittent UNC failure)
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.
These two tests can't be disambiguated at comptime, since the filesystem that the test is running on also matters for whether or not POSIX_SEMANTICS / IGNORE_READONLY_ATTRIBUTE can actually be used (since they are only supported on NTFS).
Most of this migration was performed automatically with `zig fmt`. There
were a few exceptions which I had to manually fix:
* `@alignCast` and `@addrSpaceCast` cannot be automatically rewritten
* `@truncate`'s fixup is incorrect for vectors
* Test cases are not formatted, and their error locations change
isatty on Windows is implemented as a isCygwinPty call and a GetConsoleMode call, so calling isatty just duplicates the function calls we already need to do in supportsAnsiEscapeCodes.
