Without this, we can output a mixture of '/' and '\' on platforms where
os.path.sep is '\' and prefix or outdir uses '/'. Let's always return
the path in the format of the platform we're running on.
This is needed to make the test_install_introspection() unittest work
properly on Windows.
On macOS, the temporary directory is inside /var/folders, but /var is
a symlink to /private/var, and for some reason that messes up path
traversal when you're inside the temporary directory and the source
directory is never found, and ninja runs in a loop trying to
regenerate files that can never be regenerated.
Otherwise if the list of sources changes on reconfigure after building,
the static library will contain both the old and new objects.

Without this, files() in the arguments give an error because it's a list
of mesonlib.File objects:
Array as argument 1 contains a non-string.
It also breaks in nested lists. Includes a test for this.
os.path.commonpath (and our implementation of it) both always return the
path using the native operating system path separator, so we can't just
directly compare it since the prefix could be specified in '/', and
commonpath would use '\' on Windows.
Also add a unit test for this.
A user may want to add libraries to link with in the (c|cpp)_link_args
property of the cross-compile file.
Those libraries should be at the end of the command line due to reference
resolution mechanism of the compiler.
By moving the cross_args after LINK_ARGS we are sure that specific
cross-compilation libraries are at the end of the command line.
See [github PR #1363](https://github.com/mesonbuild/meson/pull/1363) to
have the context of this change.
On some distros, running this causes Python to find the file itself as
the implementation of the `copy` module:
$ python3 copy.py
Traceback (most recent call last):
File "copy.py", line 4, in <module>
import shutil
File "/usr/lib/python3.4/shutil.py", line 14, in <module>
import tarfile
File "/usr/lib/python3.4/tarfile.py", line 48, in <module>
import copy
File "/c/Users/nirbheek/projects/meson.git/test cases/common/134 generated llvm ir/copy.py", line 6, in <module>
shutil.copyfile(sys.argv[1], sys.argv[2])
AttributeError: 'module' object has no attribute 'copyfile'
because down the import dependency chain of copy.py the 'tarfile' module
was trying to import the 'copy' standard library module but was finding
the copy.py file first because it was in the current directory.
Closes https://github.com/mesonbuild/meson/issues/1359
It's only useful to use those when you have to override include dirs
or library paths by appending them from various sources according to
the priority order, or if the compiler args need to be converted from
Unix/GCC-style to native (MSVC, for instance) style.
Sanity checks match neither of these.
Closes https://github.com/mesonbuild/meson/issues/1351
To reproduce, one could write:
foo = files('foo.c')
foo[0].path()
and get:
Traceback (most recent call last):
[snip]
File "/home/trhd/Projects/meson/mesonbuild/interpreterbase.py", line 398, in method_call
raise InvalidArguments('Variable "%s" is not callable.' % object_name)
UnboundLocalError: local variable 'object_name' referenced before assignment
Fix this by handling file objects separately.
os.path.commonpath was added in Python 3.5, so just write our own for
now. pathlib was added in Python 3.4, so this should be ok. We need to
use that instead of doing str.split() etc because Windows path handling
has a lot of exceptions and pathlib handles all that for us.
Also adds a unit test for this.
