lib/std/os.zig
This commit resolves conflicts with the changes to std.os which removed
the EAGAIN error handling interactions with the event loop. The solution
to the conflict was to apply EAGAIN => return error.WouldBlock into the
improved windows networking branch.
* remove GetModuleHandleA from kernel32.zig. use of A functions
considered harmful.
* make it a compile error to expose WinMain instead of wWinMain. same
thing.
* start code declares wWinMainCRTStartup instead of WinMainCRTStartup
when it has the choice.
This commit reimagines `std.os.windows.GetFinalPathNameByHandle`
using `DeviceIoControl` to query the OS mount manager for the DOS
(symlink) paths for the given NT volume name. In particular,
it uses `IOCTL_MOUNTMGR_QUERY_POINTS` ioctl opcode to query the
manager for the available moount points.
This commit proposes an initial draft of `GetPathNameByHandle` function
which wraps NT syscalls and strives to emulate (currently only
partially) the `kernel32.GetFinalPathNameByHandleW` function.
Previously the zig build system incorrectly assumed that the only build
artifact was a binary. Now, when you enable the cache, only the output
dir is printed to stdout, and the zig build system iterates over the
files in that directory, copying them to the output directory.
To support this change:
* Add `std.os.renameat`, `std.os.renameatZ`, and `std.os.renameatW`.
* Fix `std.os.linux.renameat` not compiling due to typos.
* Deprecate `std.fs.updateFile` and `std.fs.updateFileMode`.
* Add `std.fs.Dir.updateFile`, which supports using open directory
handles for both the source and destination paths, as well as an
options parameter which allows overriding the mode.
* Update `std.fs.AtomicFile` to support operating based on an open
directory handle. Instead of `std.fs.AtomicFile.init`, use
`std.fs.Dir.atomicFile`.
* `std.fs.AtomicFile` deinit() better handles the situation when the
rename fails but the temporary file still exists, by still
attempting to remove the temporary file.
* `std.fs.Dir.openFileWindows` is moved to `std.os.windows.OpenFileW`.
* `std.os.RenameError` gains the error codes `NoDevice`,
`SharingViolation`, and `PipeBusy` which have been observed from
Windows.
Closes#4733
Apparently NtCurrentTeb is only exported for i386 and some other
platforms but not for x86_64 nor AArch64. Let's go with the flow and
provide our own NtCurrentTeb like the Windows headers do.
Thank you Microsoft.
