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.
Some users are hitting this limit. I think it's primarily due to not
deduplicating (solved in the previous commit) but this seems like a
better limit regardless.
* make test names contain the fully qualified name
* make test filters match the fully qualified name
* allow multiple test filters, where a test is skipped if it does not
match any of the specified filters
Windows paths now use WTF-16 <-> WTF-8 conversion everywhere, which is lossless. Previously, conversion of ill-formed UTF-16 paths would either fail or invoke illegal behavior.
WASI paths must be valid UTF-8, and the relevant function calls have been updated to handle the possibility of failure due to paths not being encoded/encodable as valid UTF-8.

This also makes a long-overdue change of extracting common state from
Build into a shared Graph object.
Getting the semantics right for these flags turned out to be quite
tricky. In the end it works like this:
* The override only happens when the target is fully native, with no
additional query parameters, such as versions or CPU features added.
* The override affects the resolved Target but leaves the original Query
unmodified.
* The "is native?" detection logic operates on the original, unmodified
query. This makes it possible to provide invalid host target
information, causing confusing errors to occur. Don't do that.
There are some minor breaking changes to std.Build API such as the fact
that `b.zig_exe` is now moved to `b.graph.zig_exe`, as well as a handful
of other similar flags.
Closes#18628
This commit splits the arguments obtained from pkg-config into two
groups, cflags and libs, and consistently applies the cflags to each
individual module linking the library while applying the libs only once
for each compilation.
Uses the new `-M[name][=src]` CLI syntax to omit the source when the
module does not have a zig root source file.
Only some kinds of link objects imply that this should happen.
* Specifically recognize stderr as a different concept than an error
message in Step results.
* Display it differently when only stderr occurs but the build proceeds
successfully.

Adds a variant to the LazyPath union representing a parent directory
of a generated path.
```zig
const LazyPath = union(enum) {
generated_dirname: struct {
generated: *const GeneratedFile,
up: usize,
},
// ...
}
```
These can be constructed with the new method:
```zig
pub fn dirname(self: LazyPath) LazyPath
```
For the cases where the LazyPath is already known
(`.path`, `.cwd_relative`, and `dependency`)
this is evaluated right away.
For dirnames of generated files and their dirnames,
this is evaluated at getPath time.
dirname calls can be chained, but for safety,
they are not allowed to escape outside a root
defined for each case:
- path: This is relative to the build root,
so dirname can't escape outside the build root.
- generated: Can't escape the zig-cache.
- cwd_relative: This can be a relative or absolute path.
If relative, can't escape the current directory,
and if absolute, can't go beyond root (/).
- dependency: Can't escape the dependency's root directory.
Testing:
I've included a standalone case for many of the happy cases.
I couldn't find an easy way to test the negatives, though,
because tests cannot yet expect panics.
