script without interpreter
This is an indirect regression of e8c715786d85dcdbc367f3e379acae25a899c235; the code never accounted for ExternalPrograms that needed a harness.
|
|
These were supported for shared libraries, but for static libraries
the link_with property was never populated with `LINK_LIBRARIES` or
`INTERFACE_LINK_LIBRARIES`.
Fixes #13101
|
|
To avoid raceconditions, where one instance of meson currently downloads
a subproject defined in a wrapfile, while another either
a. starts the download itself too
b. attemts to evaluate the partially downloaded subproject
wraplock introduces a lockfile, which should prevent simultaneous access
of subprojects by wrap between different instances of meson.
|
|
DirectoryLock provides a generic locking implementation the replaces the
previously used BuildDirLock.
|
|
|
|
We'll need to evaluate those expressions before generating the AST.
Instead take a config key-value dictionary and evaluate the expression
to return a boolean.
|
|
Add cfg token to be able to parse the top level cfg() function.
Fix parser which was creating a new iterator when recursing which caused
the caller function's iterator to not have advanced when recursing
function returns.
|
|
The code that adds `--gresourcesdir=` arguments to valac based on the
source directories of GResource dependencies was incorrect. It added
the current target directory to the source path, but the GResource
source directories are already relative to the build directory.

Without this commit, the static introspection tool crashes when
introspecting systemd since certain values are `UnknownValue`
which was unexpected.
(I tested sytemd's commit hash fefcb935cd.)

Change the semantics of IntrospectionBuildTarget.source_nodes
and IntrospectionBuildTarget.extra_files .
The rewriter and the static introspection tool used to be very broken,
now it is *less* broken, hence we add some tests in this commit.
Fixes #11763

De-duplicate some code by extracting the common code into the new
`rm_src_or_extra` function.

`AstInterpreter.node_to_runtime_value` can now resolve function calls.
|
|
`resolve_node` is simply a half-broken, worse implementation of
`node_to_runtime_value` that we recently introduced.
In the example below, the static introspection tool/rewriter now
understands that the name of the executable is foo instead of bar:
```
var = 'foo'
name = var
var = 'bar'
executable(name, 'foo.c')
```
|
|
Without this commit, something like this crashes the static
introspection/rewrite tool:
```
default_options : ['warning_level='
+ run_command(['echo', '3']).stdout().strip()],
```
This commit does not reintroduce #14382.
|

Make the AstInterpreter create a directed acyclic graph (called
`dataflow_dag`) that stores the how the data flowes from one node in
the AST to another.
Add `AstInterpreter.node_to_runtime_value` which uses `dataflow_dag`
to find what value a variable at runtime will have.
We don't use dataflow_dag or node_to_runtime_value anywhere yet, but
it will prove useful in future commits.
|
|
Some of the evaluate_* functions in AstInterpreter seem very broken
and do not even evaluate all of the AST. I do not know what the
original author thought, so I just fixed it.
|
|
Replace `AstInterpreter.reverse_assignment` with
`AstInterpreter.all_assignment_nodes`.
This does not give us an immediate advantage but
will be useful in future commits.
|
|
Replace the variable tracking of `AstInterpreter.assignments`
with a slightly better variable tracking called
`AstInterpreter.cur_assignments`.
We now have a class `UnknownValue` for more explicit handling
of situations that are too complex/impossible.
|
|
The AstInterpreter now stores how deep into if/elif/else we are.
This is currently dead code, but it will be read in future commits.

To improve type-safety and readability we replace a
dictionary with a new class `IntrospectionDependency`.

Without this commit, meson thinks that the `var` token in the code below
starts at a different column number than it actually starts, because the
old author forgot to account for the length of the triple quotes.
```
'''
some multiline strings
abc''' + var
```

The parser should behave exactly as before,
but the code is a bit easier to understand now.

With introduction of dfd8cfbd8d9c VS compile is broken for cases where
/MANIFEST:EMBED linker flag is actually used. The fix keeps the default
creation of <EmbedManifest> but adopts the same strategy as e3db7af0ea41,
that is to scan the link flags for the embed case to decide state is emit
'true' or 'false' for EmbedManifest.
|
|
This allows linker arguments containing a space (or other special
character) to pass through to the linker correctly. For example, the spaces
in "test cases/windows/25 embed manifest" when using
meson.project_source_root().
|
|
The most egregious cases are Nasm (which needs to be transformed to `ASM_NASM`) and Rust (which is not yet supported by CMake).
See https://cmake.org/cmake/help/v4.0/command/project.html

Restore the behavior from before commit d37d649b0 ("Make all Meson level
options overridable per subproject.", 2025-02-13). The old code was:
options: T.MutableMapping[OptionKey, T.Any] = OrderedDict()
# process project default options
for k, v in default_options.items():
if not subproject or k.subproject == subproject:
options[k] = v
# override them with machine default and command line options
options.update(env.options)
env.options = options

The CFLAGS environment variable is used for g-ir-scanner's linking pass,
It is emptied since commit 237513dff ("modules/gnome, modules/Python:
Allow injecting RPATH flags through LDFLAGS if needed", 2025-04-09);
which could even be considered a bugfix if it didn't break Fedora
quite badly.
I could not write a testcase, but the culprit seems to be the
-specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 that Fedora places
in CFLAGS. The file contains
*cc1_options:
+ %{!r:%{!fpie:%{!fPIE:%{!fpic:%{!fPIC:%{!fno-pic:-fPIE}}}}}}
and the lack of -fPIE option upsets the linker. Fix by priming
the contents of the CFLAGS variable with the c_link_args being used
for the build.

This change ensures that Vulkan will be found in the path defined by the
VULKAN_SDK env var. This is the case when the Vulkan SDK is not
installed in a well-known location (/usr, /usr/local), but in a user's
home folder.
|
|
VULKAN_SDK is the preferred environment variable to point to
the Vulkan installation. With this change the old variable
(VK_SDK_PATH) is made optional.
|
|
Also ensure that .get_version() can be called on the output of
_find_tool by the modules (kind of required for #14422).

Make more of the first-invocation logic apply to subsequent configuration
of the build tree.
This also opens the door for using set_option_maybe_root for the
first invocation. This is a huge cleanup but also a larger change,
and therefore not something for stable branches. Leave it for later.

better version of the two as a new method of OptionStore, and use it in
OptionStore.validate_cmd_line_options.

Some libraries in CUDA are stubbed out to load the actual implementation from
the driver at runtime. One example is NVML, that only exists in `stubs/`.
Ensure that the stubs dir is searched last, like FindCUDAToolkit.cmake:
https://github.com/Kitware/CMake/blob/4f2482700b6a6231c697b1178239acf76955bfeb/Modules/FindCUDAToolkit.cmake#L1163-L1173
|

When trying to pick between a CUDA library that has both shared and static
libraries and the same basename, e.g. `libnvidia-ml.a` and `libnvidia-ml.so`,
it becomes impossible to pick a specific variant with `-l` arguments.
