Basically everything that has a direct replacement or no uses left.
Notable omissions:
- std.ArrayHashMap: Too much fallout, needs a separate cleanup.
- std.debug.runtime_safety: Too much fallout.
- std.heap.GeneralPurposeAllocator: Lots of references to it remain, not
a simple find and replace as "debug allocator" is not equivalent to
"general purpose allocator".
- std.io.Reader: Is being reworked at the moment.
- std.unicode.utf8Decode(): No replacement, needs a new API first.
- Manifest backwards compat options: Removal would break test data used
by TestFetchBuilder.
- panic handler needs to be a namespace: Many tests still rely on it
being a function, needs a separate cleanup.
added adapter to AnyWriter and GenericWriter to help bridge the gap
between old and new API
make std.testing.expectFmt work at compile-time
std.fmt no longer has a dependency on std.unicode. Formatted printing
was never properly unicode-aware. Now it no longer pretends to be.
Breakage/deprecations:
* std.fs.File.reader -> std.fs.File.deprecatedReader
* std.fs.File.writer -> std.fs.File.deprecatedWriter
* std.io.GenericReader -> std.io.Reader
* std.io.GenericWriter -> std.io.Writer
* std.io.AnyReader -> std.io.Reader
* std.io.AnyWriter -> std.io.Writer
* std.fmt.format -> std.fmt.deprecatedFormat
* std.fmt.fmtSliceEscapeLower -> std.ascii.hexEscape
* std.fmt.fmtSliceEscapeUpper -> std.ascii.hexEscape
* std.fmt.fmtSliceHexLower -> {x}
* std.fmt.fmtSliceHexUpper -> {X}
* std.fmt.fmtIntSizeDec -> {B}
* std.fmt.fmtIntSizeBin -> {Bi}
* std.fmt.fmtDuration -> {D}
* std.fmt.fmtDurationSigned -> {D}
* {} -> {f} when there is a format method
* format method signature
- anytype -> *std.io.Writer
- inferred error set -> error{WriteFailed}
- options -> (deleted)
* std.fmt.Formatted
- now takes context type explicitly
- no fmt string
Adds a CreateProcessFlags packed struct for all the possible flags to
CreateProcessW on windows. In addition, propagates the existing
`start_suspended` option in std.process.Child which was previously only
used on Darwin. Also adds a `create_no_window` option to std.process.Child
which is a commonly used flag for launching console executables on
windows without causing a new console window to "pop up".
Windows defines an `ACCESS_DENIED` error code. There is no
PERMISSION_DENIED (or its equivalent) which seems to only exist on POSIX
systems. Fix a couple Windows calls code to return `error.AccessDenied`
for `ACCESS_DENIED` and to stop mapping AccessDenied into
PermissionDenied.
Windows-only, depends on kernel32 in violation of zig std lib policy,
and redundant with other cross-platform APIs that perform the same
functionality.
This rewrite improves some error messages, hugely simplifies the logic,
and fixes several bugs. One of these bugs is technically a new rule
which Andrew and I agreed on: if a parameter has a comptime-only type
but is not declared `comptime`, then the corresponding call argument
should not be *evaluated* at comptime; only resolved. Implementing this
required changing how function types work a little, which in turn
required allowing a new kind of function coercion for some generic use
cases: function coercions are now allowed to implicitly *remove*
`comptime` annotations from parameters with comptime-only types. This is
okay because removing the annotation affects only the call site.
Resolves: #22262
* Make it work for thumb and aarch64.
* Clean up std.os.windows.teb() a bit.
I also updated stage1/zig.h since the changes are backwards-compatible and are
necessary due to the std.os.windows changes that call the newly-added functions.
It appears that ReadFile returns ERROR_BROKEN_PIPE for a broken pipe, but WriteFile returns ERROR_NO_DATA.

The old `CallingConvention` type is replaced with the new
`NewCallingConvention`. References to `NewCallingConvention` in the
compiler are updated accordingly. In addition, a few parts of the
standard library are updated to use the new type correctly.
To facilitate #1840, this commit slims `std.windows.kernel32` to only
have the functions needed by the standard library. Since this will break
projects that relied on these, I offer two solutions:
- Make an argument as to why certain functions should be added back in.
Note that they may just be wrappers around `ntdll` APIs, which would
go against #1840.
If necessary I'll add them back in *and* make wrappers in
`std.windows` for it.
- Maintain your own list of APIs. This is the option taken by bun[1],
where they wrap functions with tracing.
- Use `zigwin32`.
I've also added TODO comments that specify which functions can be
reimplemented using `ntdll` APIs in the future.
Other changes:
- Group functions into groups (I/O, process management etc.).
- Synchronize definitions against Microsoft documentation to use the
proper parameter types/names.
- Break all functions with parameters over multiple lines.
Instead of calling the dynamically loaded kernel32.GetLastError, we can extract it from the TEB.
As shown by [Wine](34b1606019/include/winternl.h (L439)), the last error lives at offset 0x34 of the TEB in 32-bit Windows and at offset 0x68 in 64-bit Windows.
- From lib/libc/include/any-windows-any/wincon.h#L235
- See also https://learn.microsoft.com/en-us/windows/console/setconsolemode
- Also add DISABLE_NEWLINE_AUTO_RETURN constant which will be used by SetConsoleMode in lib/std/os/windows.

A volume can be mounted as a NTFS path, e.g. as C:\Mnt\Foo. In that case, IOCTL_MOUNTMGR_QUERY_POINTS gives us a mount point with a symlink value something like `\??\Volume{383da0b0-717f-41b6-8c36-00500992b58d}`. In order to get the `C:\Mnt\Foo` path, we can query the mountmgr again using IOCTL_MOUNTMGR_QUERY_DOS_VOLUME_PATH.
Fixes#19731
