A bunch of files have several T.TYPE_CHECKING blocks that each do some
things which could just as well be done once, with a single `if`
statement. Make them do so.
The default behavior of installing relative to prefix may be unexpected,
and is definitely wrong in many cases.
Give users control in order to specify that yes, they actually want to
install to a venv.
This is particularly useful for projects that use meson as a build
system for a python module, where *all* files shall be installed into
the python site-packages.
This bring us in line with Autotools and CMake and it is useful
for platforms like Nix, which install projects
into multiple independent prefixes.
As a consequence, `get_option` might return absolute paths for some
directory options, if a directory outside of prefix is passed.
This is technically a backwards incompatible change but its effect
should be minimal, thanks to widespread use of `join_paths`/`/` operator
and pkg-config generator module. It should only cause an issue when
a path were constructed by concatenating the value of directory path option.
Also remove a comment about commonpath since we do not use that since
<00f5dadd5b>.

In commit e5a6283c4c, this function was
reorganized to assign value -> newvalue instead of overwriting newvalue,
but the error message case wasn't updated to match. As a result,
actually hitting the error would report an even more errory error, i.e.
a traceback.
(Actually hitting the error requires passing an array option as a python
object that isn't a list or a string. This is impossible to do from the
command line or meson_options.txt, but can be done with builtin options.)
It can be either:
- boolean: the option is completely deprecated.
- list: some choices are deprecated.
- dict: some choices are deprecated and replaced by another.
Fixes: #7444
Remove test_minor_version_does_not_reconfigure_wipe() because when run
during dev cycle that test reconfigure with .99 -> .100 which is
considered a major version change now. It is covered by a more efficient
internal test now anyway.
While at it, remove no-op `with Path(self.builddir):` statement, the
intention was clearly to set workdir.
Fixes: #9260
It is a commonly needed information to help debugging build issues. We
already were printing options with non-default value at the end of the
configure but outside of the summary.
Keeping the list of user defined options in the interpreter will also in
the future be useful to use new default value on reconfigure.
We have a lot of these. Some of them are harmless, if unidiomatic, such
as `if (condition)`, others are potentially dangerous `assert(...)`, as
`assert(condtion)` works as expected, but `assert(condition, message)`
will result in an assertion that never triggers, as what you're actually
asserting is `bool(tuple[2])`, which will always be true.
* backends: Add a Visual Studio 2013 backend
This is more-or-less a quick port from the VS2015 backend, except that
we update the Visual Studio version strings and toolset versions
accordingly. Also correct the generator string for Visual Studio 2015
in mesonbuild/cmake/common.py.
* backend: Add VS2012 backend
Similar to what we did for Visual Studio 2013, add a Visual Studio 2012
backend.
* vs2010backend.py: Implement `link_whole:` if needed
We actually need Visual Studio 2015 Update 2 to use `/WHOLEARCHIVE:`,
which is what we are currently using for `link_whole:` on Visual Studio.
For Visual Studio versions before that, we need to expand from the
static targets that were indicated by `link_whole:`, and any of the
sub-dependent targets that were pulled in via the dependent target's
`link_whole:`. This wil ensure `link_whole:` would actually work in
such cases.
* vs2010backend.py: Handle objects from generated sources
Unforunately, we can't use backends.determine_ext_objs() reliably, as
the Visual Studio backends handle this differently.
* vs2010backend.py: Fix generating VS2010 projects
Visual Studio 2010 (at least the Express Edition) does not set the envvar
%VisualStudioVersion% in its command prompt, so fix generating VS2010
projects by taking account into this, so that we can determine the location
of vcvarsall.bat correctly.
* whole archive test: Disable on vs2012/2013 backends too
The Visual Studio 2012/2013 IDE has problems handling the items that would be
generated from this test case, so skip this test when using
--backend=vs[2012|2013]. This test does work for the Ninja backend when
VS2012 or VS2013 is used, though.
Consolidate this error message with XCode along with the vs2010 backend.
* docs: Add the new vs2012 and vs2013 backends
Let people know that we have backends for vs2012 and 2013. Also let
people know that generating Visual Studio 2010 projects have been fixed
and the pre-vs2015 backends now handle the `link_whole:` project option.
We need to konw on rconfigure which options have already bee set not
just for the super project, but also for the subproject. However, using
first_invocation is not sufficient, as a reconfigure could add a new
subpproject that wasn't present before, and we need to initialize that
project's builtins.
These options often don't exist for the build machine, as they're
generally invalid (ie, prefix, libdir, etc). So we should always check
for their existance as host optiuons, since all we want to know in this
case is if the option is yeilding (valid per-subproject), and build/vs
host doesn't matter in that cases:

They are supposed to have different behavior. The environment variables
apply to both the compiler and linker when the compiler acts as a
linker, but the command line ones do not.
Fixes#8345
This fix issue when using --wipe and the machine file was passed as a
pipe and written locally, or when the file was resolved in XDG_DATA_HOME
or XDG_DATA_DIRS.
Fixes: #8560
When reverting from 0.57 to 0.56, one can see an error like this:
File /Users/pm215/src/qemu-for-merges/meson/mesonbuild/coredata.py,
line 1016, in load
obj = pickle.load(f)
ModuleNotFoundError: No module named 'mesonbuild.mesonlib.universal';
'mesonbuild.mesonlib' is not a package
FAILED: build.ninja
The reason is that the old version fails to resolve mesonbuild.mesonlib,
which is a similar situation to the existing AttributeError check. Raise
a MesonException for ModuleNotFoundError as well, so that reconfiguration
proceeds using cmd_line.txt.
