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:
Fixes#8613
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.
All changes were created by running
"pyupgrade --py3-only --keep-percent-format"
and committing the results. I have not touched string formatting for
now.
- use set literals
- simplify .format() parameter naming
- remove __future__
- remove default "r" mode for open()
- use OSError rather than compatibility aliases
- remove stray parentheses in function(generator) scopes
This has a bunch of nice features. It obviously centralizes everything,
which is nice. It also means that env is only re-read at `meson --wipe`,
not `meson --reconfigure`. And it's going to allow more cleanups.
This patches takes the options work to it's logical conclusion: A single
flat dictionary of OptionKey: UserOptions. This allows us to simplify a
large number of cases, as we don't need to check if an option is in this
dict or that one (or any of 5 or 6, actually).
I would have prefered to do these seperatately, but they are combined in
some cases, so it was much easier to convert them together.
this eliminates the builtins_per_machine dict, as it's duplicated with
the OptionKey's machine parameter.
This is useful for figuring out what kind of option this is. My hope is
that in the longterm this is less useful, but we'll still want it for
the configuration summary printing.
This is a complex key that can store multiple bits of data in a single
place. It can be generated from a command line formatted string, and
it's str method returns it to that form.
It's intentionally immutable, use the evolve() method to create
variations of an existing key.
