For instance, on Windows, if the terminal is in cp65001, the subprocess
output is not encoded correctly and it results in error when running
unit test.
Meson will implicit rpaths when *.so/*.dll/etc. files are injected onto
the link line from pkg-config and (now) cmake dependencies.
Extend the "prebuilt shared" tests to test that these are added.
This replaces all of the Apache blurbs at the start of each file with an
`# SPDX-License-Identifier: Apache-2.0` string. It also fixes existing
uses to be consistent in capitalization, and to be placed above any
copyright notices.
This removes nearly 3000 lines of boilerplate from the project (only
python files), which no developer cares to look at.
SPDX is in common use, particularly in the Linux kernel, and is the
recommended format for Meson's own `project(license: )` field
This does require hacking up the test pretty badly, since we need to not
ever pass GCC these invalid values. But it's preferable to writing
another project test I think.

Which allow passing arguments specifically to the static or shared
libraries.
For design, this is all handled in the interpreter, by the build layer
the arguments are combined into the existing fields. This limits changes
required in the mid and backend layers
Since the previous commit allows for more scenarios with name
collisions, it makes sense to expand the compile command so that it can
also take into account suffixes. i.e. meson compile -C build foo.exe can
now work if the executable has an exe suffix along with being named foo.
When checking target names, meson explictly forbids having multiple
targets with the same name. This is good, but it is strict and it is
impossible to have targets with the same basename and differing suffixes
(e.g. foo and foo.bin) in the same directory. Allow this for executables
by including the suffix (if it exists) in the interal target id. So foo
would be foo@exe and foo.bin would be foo.bin@exe.
The unittest case for `clang-tidy-fix` checks if the whole project is in
git or not, and skips if not.
Fix this by creating a temporary git repo, copy the test files and run
the tests, following how `clang-format` does.
It also reverts some help code introduced in the previous test.
Tested: Verify the test case passes.

Add the `clang-tidy-fix` target to apply clang-tidy fixes to the source
code.
This is done by calling `run-clang-tidy` with `-fix` argument.
Add a test case to run `clang-tidy-fix` and verify the file is changed.

- allow defines with leading whitespace
- always do replacement for cmakedefine
- output boolean value for cmakedefine01
- correct unittests for cmakedefine
- add cmakedefine specific unittests
Projects that prefer GNU C but can fallback to ISO C can now set for
example `default_options: 'c_std=gnu11,c11'` and it will use gnu11 when
available, fallback to c11 otherwise. It is an error only if none of the
values are supported by the current compiler.
This allows to deprecate gnuXX values from MSVC compiler, that means
that `default_options: 'c_std=gnu11'` will now print warning with MSVC
but still fallback to 'c11' value. No warning is printed if at least one
of the values is valid, i.e. `default_options: 'c_std=gnu11,c11'`.
In the future that deprecation warning will become an hard error because
`c_std=gnu11` should mean GNU is required, for projects that cannot be
built with MSVC for example.
We support this in a machine file:
```
[binaries]
pkgconfig = 'pkg-config'
pkg-config = 'pkg-config'
```
and you can use either one, because internally we look up both. If you
only set *one* of them, this plays awkwardly with setting $PKG_CONFIG,
since we don't know which one you set in the machine file and the
*other* one will be initialized from the environment instead.
In commit 22df45a319 we changed program
lookup of config-tool style dependencies to use the regular tool names
and only fall back on the strange internal names. This affected the
pkg-config class too.
The result is that instead of preferring `pkgconfig =` followed by
$PKG_CONFIG followed by `pkg-config =`, we inverted the lookup order.
This is a good idea anyway, because now it behaves consistently with
`find_program('pkg-config')`.
Unfortunately, we documented the wrong name in a bunch of places, and
also used the wrong name in various testsuite bits, which meant that if
you set $PKG_CONFIG and then ran the testsuite, it would fail.
Correct these references, because they are buggy.
One test case expected to find_program() a native copy for convenience
of testing against natively installed glib. Force it to resolve a native
copy.
By default, pdb assumes that any command run is python code to be
evaluated, but only if that code isn't a builtin pdb command. You can
force it to be evaluated as python code by prefixing it with `!`.
It's handy to simply name a python variable and have its variable be
printed.
But single letter variables like 's' and 'p' make debugging with pdb
commands (i.e. 's'tep, and 'p'rint evaluated expressions) less
convenient, and potentially confusing.
This fixes two issues in constructing the default installation path
when install_dir is not specified:
- inside a subproject, install_data() would construct the destination
path using the parent project name instead than the current project
name,
- when specifying preserve_path, install_data() would construct the
destination path omitting the project name.
Fixes#11910.
By specifiying explicit encodings, we can silence warnings like:
/__w/meson/meson/test cases/common/100 postconf with args/postconf.py:15: EncodingWarning: 'encoding' argument not specified
with open(input_file) as f:
in CI.
Replace unencodable XML chars with their printable representation, so
that, xmllint can parse test outputs without error.

This saves on a 1500-line import at startup and may be skipped entirely
if no compiled languages are used. In exchange, we move the
implementation to a new file that is imported instead.
Followup to commit ab20eb5bbc.
This lessens the amount of code imported at Meson startup by mapping
each dependency to a dictionary entry and using a programmable import to
dynamically return it.
Minus 16 files and 6399 lines of code imported at startup.
When meson is installed as editable, setuptools adds
`__editable___meson_1_0_99_finder` to the list. This contains the string
"meson" which isn't really accurate to what we want, which is modules
that are part of the `mesonbuild.*` namespace.
Allow the use of wildcards (e.g. *) to match test names in `meson test`.
Raise an error is given test name does not match any test.
Optimize the search by looping through the list of tests only once.
- add `extra_paths` to intro-tests.json to know paths needed to run a
test on Windows;
- add `depends` to alias targets in intro-targets.json to know what
targets does an alias point to;
- add `depends` to intro-dependencies.json to know libraries linked with
an internal dependency;
- renamed `deps` to `dependencies` in `intro-dependencies.json` for more
uniformity.
To take good decisions we'll need to know if we are a Rust library which
is only know after processing source files and compilers.
Note that is it not the final list of compilers, some can be added in
process_compilers_late(), but those are compilers for which we don't
have source files any way.
This will help with the writing of tools to generate
VisualStudio project and solution files, and possibly
for other IDEs as well.
- Used compilers a about `host`, `build` and `target` machines
arere listed in `intro-compilers.json`
- Informations lister in `intro-machines.json`
- `intro-dependencies.json` now includes internal dependencies,
and relations between dependencies.
- `intro-targets.json` now includes dependencies, `vs_module_defs`,
`win_subsystem`, and linker parameters.
The paths in meson.build use / as path separator, however, the paths
constructed during the directory structure walk use native path
separators, thus the path never compare equal to the excluded ones.
Normalize the exclusion paths before the comparison.
Also prevent from using a parent directory as builddir by mistake.

- MesonException for errors is clearer than SystemExit('error message')
and provides meson-formatted "ERROR: ..."
- `raise SystemExit` with no parameter isn't obvious that it intends to
exit successfully
While clarifying the latter, it was observed to cause
test_preprocessor_checks_CPPFLAGS() failure to be ignored. That test
checks get_define() on both c and cpp compilers, which means we need to
define either CPPFLAGS or both CFLAGS+CXXFLAGS.
CI runs with vs2019 and we were passing --backend=vs. This fix
reconfigure tests because we can't reconfigure with --backend=vs when
initial configuration determined the backend is actually vs2019.
This was added in f774609 to only change the access time of the
coredata file if the coredata struct actually changed. However,
this doesn't work as pickle serializations aren't guaranteed to
be stable. Instead, let's manually check if options have changed
values and skip the save if they haven't changed.
We also extend the associated unit test to cover all the option
types and to ensure that configure does get executed if one of the
options changes value.
This test checks that rpaths are stripped correctly when their prefix
matches the source directory.
This test fails without the previous commit:

These are necessary for projects outside Meson itself that want to
