std.Thread.Pool: back to spawning all threads in initialization because
it's overall simpler. This scheme requires init to be passed a pointer
to the struct.
std.process.Child: implement integration with thread pool jobserver. The
environment variable is called `JOBSERVERV2`. The API works based on
assigning a thread pool to the child process.
build runner: store the thread pool in std.Build.Graph so that it can be
passed to child processes during the make phase.
Fix not allocating +1 pollfds in previous commit.
The actual `zig objcopy` does not accept keeping multiple sections.
If you pass multiple `-j .section` arguments to `zig objcopy`, it will
only respect the last one passed.
Originally I changed `zig objcopy` to accept multiple sections
and then concatenate them instead of returning after outputting the
first section (see emitElf) but I realized concatenating probably doesn't make sense.
The docs for setting stdio to "inherit" say:
It also means that this step will obtain a global lock to prevent other
steps from running in the meantime.
The implementation of this lock was missing but is now provided by this
commit.

Introduces `disable_zig_progress` which prevents the build runner from
assigning the child process a progress node.
This is needed for the empty_env test which requires the environment to
be completely empty.
This allows running commands that take an output directory argument. The
main thing that was needed for this feature was generated file subpaths,
to allow access to the files in a generated directory. Additionally, a
minor change was required to so that the correct directory is created
for output directory args.
* `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
This replaces `extra_file_dependencies` with support for lazy paths.
Also assert output file basenames are not empty, avoid improper use of
field default values, ensure stored strings are duplicated, and
prefer `ArrayListUnmanaged` to discourage misuse of direct field access
which wouldn't add step dependencies.
Adds an `include_paths` field to RcSourceFile that takes a slice of LazyPaths. The paths are resolved and subsequently appended to the -rcflags as `/I <resolved path>`.
This fixes an accidental regression from https://github.com/ziglang/zig/pull/19174. Before that PR, all Win32 resource compilation would inherit the CC flags (via `addCCArgs`), which included things like include directories. After that PR, though, that is no longer the case.
However, this commit intentionally does not restore the previous behavior (inheriting the C include paths). Instead, each .rc file will need to have its include paths specified directly and the include paths only apply to one particular resource script. This allows more fine-grained control and has less potentially surprising behavior (at the cost of some convenience).

This function incorrectly assumed that module name subsections, function
name subsections, and local name subsections are encoded the same,
however according to
[the specification](https://webassembly.github.io/spec/core/appendix/custom.html)
they are encoded differently.
This commit adds support for parsing module name subsections correctly,
which started appearing after upgrading to LLVM 18.
Windows does not support RPATH and only searches for DLLs in a small
number of predetermined paths by default, with one of them being the
directory from which the application loaded.
Installing both executables and DLLs to `bin/` by default helps ensure
that the executable can find any DLL artifacts it has linked to.
DLL import libraries are still installed to `lib/`.
These defaults match CMake's behavior.
This is a partial revert of 105db13536.
As we learned from Void Linux packaging, these options are not actually
helpful since the distribution package manager may very well want to
cross-compile the packages that it is building.
So, let's not overcomplicate things. There are already the standard
options: -Dtarget, -Dcpu, and -Ddynamic-linker.
These options are generally provided when the project generates machine
code artifacts, however, there may be a project that does no such thing,
in which case it makes sense for these options to be missing. The Zig
Build System is a general-purpose build system, after all.
The previous commit deleted the deprecated API and then made all the
follow-up changes; this commit reverts only the breaking API changes.
This commit can be reverted once 0.12.0 is tagged.
This adds the *std.Build owner to LazyPath so that lazy paths returned
from a dependency can be used in the application without friction or
footguns.
closes#19313
Previously, `Step.Compile.installHeader` and friends would incorrectly
modify the default `install` top-level step, when the intent was for
headers to get bundled with and installed alongside an artifact. This
change set implements the intended behavior.
This carries with it some breaking changes; `installHeader` and
`installConfigHeader` both have new signatures, and
`installHeadersDirectory` and `installHeadersDirectoryOptions` have been
merged into `installHeaders`.
`{}` for decls
`{p}` for enum fields
`{p_}` for struct fields and in contexts following a `.`
Elsewhere, `{p}` was used since it's equivalent to the old behavior.
