2025-06-05build: fix tasking compiler b_lto support after option refactorDylan Baker1-4/+4
The weird format is to minimize the diff in the next fixup patch.
2025-06-05unittests: Handle missing compiler support in test_compiler_detectionDylan Baker1-5/+30
This wraps all of the compiler detections in this test case in try/except blocks. These blocks will return a skipTest for Python >= 3.11 (where subTest and skipTest interact correctly), and continue if they do not. For Meson CI runs they will fail the specific subtest, which is also an improvement as it can help pinpoint exactly which subtest failed. Fixes: #14579
2025-06-05unittests: add asserts to test_compiler_detectionDylan Baker1-0/+2
Add a few asserts for functions that could in theory return None, but if they do something has gone *really* wrong with the test.
2025-06-05unittests: use subtests to break up test_compiler_detectionDylan Baker1-99/+106
Which is a very large and complicated test function

2025-06-04utils: Support VCSs that can have file repodirsDylan Baker1-3/+16
When git is used with worktrees, `.git` will be a file containing a link to the original repo. Currently, we say that this is not git because `.git` isn't a directory.

2025-06-03gnome.mkenums: Fix get_executable_serialisation passing ExternalPrograms ↵L. E. Segovia1-3/+1
script without interpreter This is an indirect regression of e8c715786d85dcdbc367f3e379acae25a899c235; the code never accounted for ExternalPrograms that needed a harness.
2025-06-03cmake: Fix target_link_libraries against project targetsL. E. Segovia2-5/+23
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
2025-06-03wrap: Lock subproject directory when downloading wrapsFlorian "sp1rit"​4-4/+17
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.
2025-06-03utils: Replace BuildDirLock with generic DirectoryLockFlorian "sp1rit"​5-27/+56
DirectoryLock provides a generic locking implementation the replaces the previously used BuildDirLock.

2025-05-31cargo: Do not convert cfg() to Meson ASTXavier Claessens2-107/+36
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.
2025-05-31cargo: Fix cfg() parsingXavier Claessens2-50/+69
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.
2025-05-31Vala: Add test for generated UI in subdirectoriesJames Westman5-0/+54
2025-05-31Vala: Fix GResource source directoriesJames Westman1-1/+1
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.

2025-05-29rewriter: Bugfix concerning `UnknownValue`Volker Weißmann3-5/+12
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.)
2025-05-29rewriter: Rewrite how we add/remove source filesVolker Weißmann17-311/+715
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
2025-05-29rewriter refactoring: Add rm_src_or_extraVolker Weißmann1-82/+63
De-duplicate some code by extracting the common code into the new `rm_src_or_extra` function.
2025-05-29rewriter: Improve find_target and find_dependencyVolker Weißmann2-49/+54
2025-05-29mesonbuild/ast: make mypy safeVolker Weißmann2-13/+7
2025-05-29Add AstInterpreter.funcvalsVolker Weißmann2-15/+112
`AstInterpreter.node_to_runtime_value` can now resolve function calls.
2025-05-29AstInterpreter: Replace resolve_node with node_to_runtime_valueVolker Weißmann4-121/+31
`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') ```
2025-05-29rewriter: Remove apparently useless code.Volker Weißmann1-20/+0
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.
2025-05-29Add AstInterpreter.dataflow_dagVolker Weißmann4-0/+338
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.
2025-05-29AstInterpreter: Fix evaluate_* functionsVolker Weißmann1-33/+23
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.
2025-05-29rewriter: Refactoring of assignment trackingVolker Weißmann2-10/+8
Replace `AstInterpreter.reverse_assignment` with `AstInterpreter.all_assignment_nodes`. This does not give us an immediate advantage but will be useful in future commits.
2025-05-29rewriter: Replace assignments with cur_assignmentsVolker Weißmann5-29/+147
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.
2025-05-29Add AstInterpreter.nestingVolker Weißmann1-0/+4
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.
2025-05-29rewriter.py: make type safeVolker Weißmann4-104/+137
2025-05-29rewriter: Add IntrospectionDependencyVolker Weißmann4-25/+35
To improve type-safety and readability we replace a dictionary with a new class `IntrospectionDependency`.
2025-05-29rewriter: Add IntrospectionBuildTargetVolker Weißmann4-63/+81
To improve type-safety and readability we replace a dictionary with a new class `IntrospectionBuildTarget`.
2025-05-29rewritetests.py: Ignore order of listed sourcesVolker Weißmann1-10/+22
The order in which the rewriter outputs the listed sources is more or less arbitrary anyways, so we ignore it to prevent the tests from breaking after small irrelevant changes.
2025-05-29Refactoring and removal of dead codeVolker Weißmann3-30/+9
2025-05-29parser: Fix colno after multiline stringsVolker Weißmann1-1/+1
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 ```
2025-05-29AstPrinter: Add parenthesis where neccessaryVolker Weißmann1-2/+44
2025-05-29parser: Simplify precedence levelsVolker Weißmann1-27/+25
The parser should behave exactly as before, but the code is a bit easier to understand now.
2025-05-29AstPrinter: Use str.translate instead of str.replaceVolker Weißmann1-1/+3
2025-05-29rewriter: Don't ignore the `name_prefix` kwargVolker Weißmann1-1/+1
2025-05-26vs2010backend: fix EmbedManifest state when /MANIFEST:EMBED is usedPeter Harris4-3/+28
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.
2025-05-26vs2010backend: Escape linker argumentsPeter Harris1-2/+3
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().
2025-05-25ci: ubuntu-rolling: update for zig distfile renamingSam James1-1/+1
