Currently C++ inherits C, which can lead to diamond problems. By pulling
the code out into a standalone mixin class that the C, C++, ObjC, and
Objc++ compilers can inherit and override as necessary we remove one
source of diamonding. I've chosen to split this out into it's own file
as the CLikeCompiler class is over 1000 lines by itself. This also
breaks the VisualStudio derived classes inheriting from each other, to
avoid the same C -> CPP inheritance problems. This is all one giant
patch because there just isn't a clean way to separate this.
I've done the same for Fortran since it effectively inherits the
CCompiler (I say effectively because was it actually did was gross
beyond explanation), it's probably not correct, but it seems to work for
now. There really is a lot of layering violation going on in the
Compilers, and a really good scrubbing would do this code a lot of good.
Mypy know what to do with these and isn't confused, but some versions of
python 3.5 (at least 3.5.2) can't handle these annotations. By making
them strings the python interpreter wont try to evaluate them.
Fixes#5326
When we create a dependency as part of another dependency (say Threads),
we want to pass down most of the methods (like required). Currently
however, there is the possibility that we can pass down invalid keyword
arguments, such as 'method'. This new method is meant to work around
that my simplifying and centralizing how we pass these dependencies
down.
It turns out there's a bug in creating a sub dependency out of threads
in that we pass all of the kwargs from the parent to the
ThreadDependency instance. This demonstrates the bug.
For consistency, it can be useful to have an explicit empty test suite list
for a test:
test('test-name', binary, suite: [])
This currently passes meson but fails when running meson tests:

Fix it by simply checking for the test suite to be a valid list we can pass on

Some things, like `method[...](...)` or `x: ... = ...` python 3.5
doesn't support, so I made a comment instead with the intention that it
can someday be made into a real annotation.
* docs: document unrecognized escape sequence behaviour [skip ci]
Document that unrecognized escape sequence behaviour is like python, not
C.
* Don't try to decode invalid hex escape sequences
Don't try to decode escape sequences which should contain a sequence of
hex digits, but don't, throwing a python exception. These will treated
literally instead.
* Extend test case to cover invalid escape sequences
Previously, this called out to the %ninja_test macro to run the
tests, but that limits us to only the arguments that ninja can
understand. In particular, it is not possible to add a test
timeout multiplier (such as is sometimes needed when building for
slow architectures such as armv7hl). With this patch, it will be
possible to specify `%meson_test -t 5` in the RPM spec file
without needing to patch the sources to extend the timeouts,
making life easier for packagers.
