Previously Meson would use the name of the first .vala source file. This
doesn't work for some projects. Tracker is one example: it has
several libraries that mix Vala and C code. In such cases, none of the
.vala files tend to bear the name of the library we actually want to
generate.
This allows defining test suites for test-valgrind target without the risk
of e.g. being unable to differentiate the targets test-valgrind (testing
with valgrind) from test-valgrind (testing the valgrind subproject).
The directory from where the source files are sought when producing a
coverage report in text or XML format should not be the build directory
but the source directory instead.
Instead, return the values of the test and benchmark setup data files so
that the ninja/osx/vs backends can use those filenames instead of
hard-coding them.
When a CustomTarget is run with a command that is an executable built
by the project which also has a DLL built in the same project as a
dependency, the EXE can't run on Windows because the DLL can't be found.
On UNIX-like systems, we set the RPATH using the linker so these
dependencies can be found, but on Windows the only way is to set the
PATH environment variable.
The same problem exists for tests, so we reuse that infrastructure by
creating a new meson_exe.py script that can be used as a wrapper to run
CustomTarget commands on Windows. This can later also be extended to add
support for setting an environment while calling the command needed to
generate a CustomTarget: https://github.com/mesonbuild/meson/issues/266
On MSVC, shared libraries only export symbols that have been explicitly exported
either as part of the symbol prototype or via a module definitions file.
On compilers other than MSVC, all symbols are exported in the shared library by
default and the format for the list of symbols to export is different, so this
is only used with the VisualStudio compiler.
The module defs file path can either be relative to the current source directory
or an absolute path using meson.source_root() + '/some/path'
This is very useful to prevent compiler noise about invalid cflags; particularly
for the -mms-bitfields cflag which most libraries send to the mingw-gcc
compiler. More can be added later.
Instead of checking if we're on Windows and not even trying, try to symlink and
if that fails due to insufficient privileges, then just continue. This allows
people who know what they're doing to allow users other than Administrators to
make symlinks on Windows, or allows them to just run Meson as an Administrator.
