* 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
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.
This isn't technically needed since per-module -I args can suffice, but
this can produce very long CLI invocations when several --mod args are
combined with --search-prefix args since the -I args have to be repeated
for each module.
This is a partial revert of ecbe8bbf2df2ed4d473efbc32e0b6d7091fba76f.
This change is seemingly insignificant but I actually agonized over this
for three days. Some other things I considered:
* (status quo in master branch) make Compile step creation functions
accept a Target.Query and delete the ResolvedTarget struct.
- downside: redundantly resolve target queries many times
* same as before but additionally add a hash map to cache target query
resolutions.
- downside: now there is a hash map that doesn't actually need to
exist, just to make the API more ergonomic.
* add is_native_os and is_native_abi fields to std.Target and use it
directly as the result of resolving a target query.
- downside: they really don't belong there. They would be available
as comptime booleans via `@import("builtin")` but they should not
be exposed that way.
With this change the downsides are:
* the option name of addExecutable and friends is `target` instead of
`resolved_target` matching the type name.
- upside: this does not break compatibility with existing build
scripts
* you likely end up seeing `target.result.cpu.arch` rather than
`target.cpu.arch`.
- upside: this is an improvement over `target.target.cpu.arch` which
it was before this commit.
- downside: `b.host.target` is now `b.host.result`.
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.
This moves many settings from `std.Build.Step.Compile` and into
`std.Build.Module`, and then makes them transitive.
In other words, it adds support for exposing Zig modules in packages,
which are configured in various ways, such as depending on other link
objects, include paths, or even a different optimization mode.
Now, transitive dependencies will be included in the compilation, so you
can, for example, make a Zig module depend on some C source code, and
expose that Zig module in a package.
Currently, the compiler frontend autogenerates only one
`@import("builtin")` module for the entire compilation, however, a
future enhancement will be to make it honor the differences in modules,
so that modules can be compiled with different optimization modes, code
model, valgrind integration, or even target CPU feature set.
