This patch exploits the information residing in ltversion to set the
-compatibility_version and -current_version flags that are passed to the
linker on macOS.
This way they override all other arguments. This matches the order of
link arguments too.
Note that this means -I flags will come in afterwards and not override
anything else, but this is correct since that's how toolchain paths
work normally too -- they are searched last.

The linkers currently do not support ninja compatible output of
dependencies used while linking. Try to guess which files will be used
while linking in python code and generate conservative dependencies to
ensure changes in linked libraries are detected.
This generates dependencies on the best match for static and shared
linking, but this should not be a problem, except for spurious
rebuilding when only one of them changes, which should not be a problem.
Also makes sure to ignore any libraries generated inside the build, to
keep the optimisation working where changes in a shared library only
cause relink if the symbols have changed as well.
Restore subproject exclusion for the html coverage report that existed
in the ninja backend legacy target.
Also exclude subprojects for the gcovr generated reports.
ninja coverage -> generate all possible reports (text, xml, html)
depending on gcovr and/or lcov/genhtml availability.
ninja coverage-html -> generate only html report
ninja coverage-xml -> generate only xml report
ninja coverage-text -> generate only text report
Make all targets phony, the old legacy rules where just annoying as
you would have to remove the old report before being able to generate
a new one.
ninja coverage succeeds if it can generate at least one report.
ninja coverage-* only succeeds if it can generate the requested report
Fixes the bug with flat layout and identical target names in subprojects.
Without this change directories are not created with subproject prefix
and they can collide.
Remove dead makedirs code in Backend.__init__(), during initialization
of backend build.targets is empty. Create output directories in
Vs2010Backend.generate_projects() instead.
Also use double blank line in run_unittests.py according to
https://www.python.org/dev/peps/pep-0008/#blank-lines.
Modern gcovr includes html generation support so if lcov and
genhtml are not available fallback to gcovr.
Kept lcov and genhtml as default so to not surprise existing
users of coverage-html with the different output of gcovr.
gcovr added html support in 3.0 but as there already is a test
for 3.1 because of the changes to -r/--rootdir I opted to only
allow html generation for >= 3.1 to keep things simple.
In gcovr 3.1 the -r/--rootdir argument changed meaning causing
reports generated with gcovr 3.1 to not find the source files
and look for *.gcda in the whole source tree rather than the
build dir.
So, detect gcovr version and if 3.1 give build_root to -r instead
of source_root.
Change the code to store D properties as plain data. Only convert them
to compiler flags in the backend. This also means we can fully parse D
arguments without needing to know the compiler being used.
When building a Rust target with Rust library dependencies, an
`--extern` argument is now specified to avoid ambiguity between the
dependency library, and any crates of the same name in `rustc`'s
private sysroot.
Includes an illustrative test case.
The documentation doesn't require it and the interpreter code works around the
possibility of it being None. The ninja backend code however fails with
File "/home/whot/code/meson/mesonbuild/backend/ninjabackend.py", line 796, in generate_data_install
dstabs = os.path.join(subdir or None, plain_f)
File "/usr/lib64/python3.6/posixpath.py", line 78, in join
a = os.fspath(a)
TypeError: expected str, bytes or os.PathLike object, not NoneType
If install_dir is missing, default to datadir/projectname
We missed one particular edge-case in #2413: when the generated vala
file is inside --basedir, the path is not just the basename.c
Since this case can never happen in a project test, this includes a unit
test for the same.

- Pass exclude_files and exclude_directories relative to src_dir,
same as specified by user and documented in public install_subdir().
- Make do_copydir() interface similar to do_copyfile():
install src_dir contents to dst_dir.
- Remove src_prefix/src_dir code, it adds confusion and duplicates arguments.
Use single src_dir parameter instead.
- Make callers specify that src_dir contents should be installed
under dst_dir/basename(src_dir) if necessary.
- Use os.path.relpath() instead of string manipulations on paths.
- Add documentation to do_copydir(): specify types and add usage example.
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.

Currently, we only consider the build depends of the Executable being
run when serializing custom targets. However, this is not always
sufficient, for example if the executable loads modules at runtime or if
the executable is actually a python script that loads a built module.
For these cases, we need to set PATH on Windows correctly or the custom
target will fail to run at build time complaining about missing DLLs.
Currently, run_target does not get namespaced for each subproject,
unlike executable and others. This means that two subprojects sharing
the same run_target name cause meson to crash.
Fix this by moving the subproject namespacing logic from the BuildTarget
class to the Target class.
This allows a CustomTarget to be indexed, and the resulting indexed
value (a CustomTargetIndex type), to be used as a source in other
targets. This will confer a dependency on the original target, but only
inserts the source file returning by index the original target's
outputs. This can allow a CustomTarget that creates both a header and a
code file to have it's outputs split, for example.
