* get_library_naming: Use templates instead of suffix/prefix pairs
This commit does not change functionality, and merely sets the
groundwork for a more flexibly naming implementation.
* find_library: Fix manual searching on OpenBSD
On OpenBSD, shared libraries are called libfoo.so.X.Y where X is the
major version and Y is the minor version. We were assuming that it's
libfoo.so and not finding shared libraries at all while doing manual
searching, which meant we'd link statically instead.
See: https://www.openbsd.org/faq/ports/specialtopics.html#SharedLibs
Now we use file globbing to do searching, and pick the first one
that's a real file.
Closes https://github.com/mesonbuild/meson/issues/3844
* find_library: Fix priority of library search in OpenBSD
Also add unit tests for the library naming function so that it's
absolutely clear what the priority list of naming is.
Testing is done with mocking on Linux to ensure that local testing
is easy
Instead of just printing the message in the exception, if it's
a MesonException, also print the file and the line number. If it's an
unknown exception, print the entire traceback so that we can pin-point
what the Meson bug causing it is.
It's possible that the configuration data object has components added
conditionally, and that sometimes an empty configuration data object
is passed on purpose.
Instead, we do the substitution and also warn if no tokens were found
that could've been substituted.
Closes https://github.com/mesonbuild/meson/issues/3826
We now pass the current subproject to every FeatureNew and
FeatureDeprecated call. This requires a bunch of rework to:
1. Ensure that we have access to the subproject in the list of
arguments when used as a decorator (see _get_callee_args).
2. Pass the subproject to .use() when it's called manually.
3. We also can't do feature checks for new features in
meson_options.txt because that's parsed before we know the
meson_version from project()
* Use _get_callee_args to unwrap function call arguments, needed for
module functions.
* Move some FeatureNewKwargs from build.py to interpreter.py
* Print a summary for featurenew only if conflicts were found. The
summary now only prints conflicting features.
* Report and store featurenew/featuredeprecated only once
* Fix version comparison: use le/ge and resize arrays to not fail on
'0.47.0>=0.47'
Closes https://github.com/mesonbuild/meson/issues/3660
Input files can be in any file encoding, not just utf-8 or isolatin1. Meson
should not make assumptions here and allow for the user to specify the
encoding to use.
Start the process by traversing the tree and adding the S_IWRITE and
S_IREAD bits to the file's mode (which are also preserved on Windows.)
This fixes windows_proof_rmtree's inability to remove read-only files,
which was uncovered in testing the new `install_mode` feature.
Tested: ./run_tests.py passes on Linux, appveyor CI on Windows passes.
Instead of using fragile guessing to figure out how to invoke meson,
set the value when meson is run. Also rework how we pass of
meson_script_launcher to regenchecker.py -- it wasn't even being used
With this change, we only need to guess the meson path when running
the tests, and in that case:
1. If MESON_EXE is set in the env, we know how to run meson
for project tests.
2. MESON_EXE is not set, which means we run the configure in-process
for project tests and need to guess what meson to run, so either
- meson.py is found next to run_tests.py, or
- meson, meson.py, or meson.exe is in PATH
Otherwise, you can invoke meson in the following ways:
1. meson is installed, and mesonbuild is available in PYTHONPATH:
- meson, meson.py, meson.exe from PATH
- python3 -m mesonbuild.mesonmain
- python3 /path/to/meson.py
- meson is a shell wrapper to meson.real
2. meson is not installed, and is run from git:
- Absolute path to meson.py
- Relative path to meson.py
- Symlink to meson.py
All these are tested in test_meson_commands.py, except meson.exe since
that involves building the meson msi and installing it.
There are cases when it is useful to wrap the main meson executable with
a script that sets up environment variables, passes --cross-file, etc.
For example, in a Yocto SDK, we need to point to the right meson.cross
so that everything "just works", and we need to alter CC, CXX, etc. In
such cases, it can happen that the "meson" found in the path is actually
a wrapper script that invokes the real meson, which may be in another
location (e.g. "meson.real" or similar).
Currently, in such a situation, meson gets confused because it tries to
invoke itself using the "meson" executable (which points to the wrapper
script) instead of the actual meson (which may be called "meson.real" or
similar). In fact, the wrapper script is not necessarily even Python, so
the whole thing fails.
Fix this by using Python imports to directly find mesonmain.py instead
of trying to detect it heuristically. In addition to fixing the wrapper
issue, this should make the detection logic much more robust.
The added format argument for configure_file allows to specify the kind of
file that is treated. It defaults to 'meson', but can also have the 'cmake'
or 'cmake@' value to treat config.h.in files in the cmake format with #cmakedefine
statements.
Starting from 8fc4244187, tests
failed on my system (python 3.6 arch) because
shutil.which('meson.py') returns 'meson.py', not './meson.py'.
Refactor that codepath by using os.path.isabs instead of
"m_dir == '.'", also remove the adjacent comment because
it doesn't make much sense.
According to Python documentation[1] dirname and basename
are defined as follows:
os.path.dirname() = os.path.split()[0]
os.path.basename() = os.path.split()[1]
For the purpose of better readability split() is replaced
by appropriate function if only one part of returned tuple
is used.

teach detect_meson_py_location() that meson.py is not the
only one meson executable (there's wraptool + legacy scripts)
that could be installed to the PATH folder
fixes#2810
We can now specify the library type we want to search for, and whether
we want to prefer static libraries over shared ones or the other way
around. This functionality is not exposed to build files yet.
