The logic used to allow providing a path for setting the CWD of a child process in https://codeberg.org/ziglang/zig/pulls/31090 applies here as well:
- Windows must provide a path when setting the CWD, so the path of an `Io.Dir` must be resolved before actually calling RtlSetCurrentDirectory_U
- A directory handle may have multiple paths associated with it, so providing the CWD as a string retains a legitimate use case in cases where the precise path matters
In Zig standard library, Dir means an open directory handle. path
represents a file system identifier string. This function is better
named after "current path" than "current dir". "get" and "working" are
superfluous.
There's a good argument to not have this in the std lib but it's more
work to remove it than to leave it in, and this branch is already
20,000+ lines changed.
This reverts commit b461d07a54.
After some discussion in the team, we've decided that this is too disruptive,
especially because the linker errors are less than helpful. That's a fixable
problem, so we might reconsider this in the future, but revert it for now.
besides simply being redundant work, the now removed normalize call would cause
spawn to errantly fail (BadPath) when passing a relative path which traversed
'above' the current working directory. This case is already handled by leaving
normalization to the windows.wToPrefixedFileW call in
windowsCreateProcessPathExt
* `doc/langref` formatting
* upgrade `.{ .path = "..." }` to `b.path("...")`
* avoid using arguments named `self`
* make `Build.Step.Id` usage more consistent
* add `Build.pathResolve`
* use `pathJoin` and `pathResolve` everywhere
* make sure `Build.LazyPath.getPath2` returns an absolute path
Introduce the concept of "target query" and "resolved target". A target
query is what the user specifies, with some things left to default. A
resolved target has the default things discovered and populated.
In the future, std.zig.CrossTarget will be rename to std.Target.Query.
Introduces `std.Build.resolveTargetQuery` to get from one to the other.
The concept of `main_mod_path` is gone, no longer supported. You have to
put the root source file at the module root now.
* remove deprecated API
* update build.zig for the breaking API changes in this branch
* move std.Build.Step.Compile.BuildId to std.zig.BuildId
* add more options to std.Build.ExecutableOptions, std.Build.ObjectOptions,
std.Build.SharedLibraryOptions, std.Build.StaticLibraryOptions, and
std.Build.TestOptions.
* remove `std.Build.constructCMacro`. There is no use for this API.
* deprecate `std.Build.Step.Compile.defineCMacro`. Instead,
`std.Build.Module.addCMacro` is provided.
- remove `std.Build.Step.Compile.defineCMacroRaw`.
* deprecate `std.Build.Step.Compile.linkFrameworkNeeded`
- use `std.Build.Module.linkFramework`
* deprecate `std.Build.Step.Compile.linkFrameworkWeak`
- use `std.Build.Module.linkFramework`
* move more logic into `std.Build.Module`
* allow `target` and `optimize` to be `null` when creating a Module.
Along with other fields, those unspecified options will be inherited
from parent `Module` when inserted into an import table.
* the `target` field of `addExecutable` is now required. pass `b.host`
to get the host target.
Justification: exec, execv etc are unix concepts and portable version
should be called differently.
Do no touch non-Zig code. Adjust error names as well, if associated.
Closes#5853.
On Windows, a directory that's set as the current working directory is
not allowed to be removed. This can cause error on `deleteTree` if the
CWD is set to the file to be removed and will cause `error.FileBusy`.
However, due to `tmp.cleanup()` ignoring the errors, the folder removal error will
be ignored. The only test violating this is `windows_spawn`. As a
solution, setting the parent directory to be the CWD before deletion
will allow the cleanup to pass.
In master branch this test tests native Windows. In this branch, I
accidentally made aarch64-windows test x86_64-windows which caused some
subtle behavior that we aren't ready to add test coverage for yet.
Fixes a regression caused by https://github.com/ziglang/zig/pull/13983
From the added comment:
We still search the path if the cwd is absolute because of the
"cwd set in ChildProcess is in effect when choosing the executable path
to match posix semantics" behavior--we don't want to skip searching
the PATH just because we were trying to set the cwd of the child process.
