when that statement gets evaluated, the interpreter remembers the
version target and if it was part of the evaluation of a `if` condition
then the target meson version is temporally overriden within that
if-block.

- Exceptions raised during subproject setup were ignored.
- Allow c_stdlib in native file, was already half supported.
- Eliminate usage of subproject variable name by overriding
'<lang>_stdlib' dependency name.
This creates a full set of option in environment that mirror those in
coredata, this mirroring of the coredata structure is convenient because
lookups int env (such as when initializing compilers) becomes a straight
dict lookup, with no list iteration. It also means that all of the
command line and machine files are read and stored in the correct order
before they're ever accessed, simplifying the logic of using them.
This is like the project options, but for meson builtin options.
The only real differences here have to do with the differences between
meson builtin options and project options. Some meson options can be set
on a per-machine basis (build.pkg_config_path vs pkg_config_path) others
can be set on a per-subproject basis, but should inherit the parent
setting.
'native:' keyword was only added in 0.54. For projects declaring
meson_version >= 0.54, warn, because those projects can and should set
the keyword. For older projects declaring support for older versions,
don't warn and use the default implicitly.
Fixes https://github.com/mesonbuild/meson/issues/6849.
We don't need the legacy variable name system as for dependency()
fallbacks because meson.override_find_program() is largely used already,
so we can just rely on it.
This fix the following common pattern, we don't want to implicitly
fallback on the first line:
foo_dep = dependency('foo', required: false)
if not foo_dep.found()
foo_dep = cc.find_library('foo', required : false)
if not foo_dep.found()
foo_dep = dependency('foo', fallback: 'foo')
endif

When meson is currently being run with a python that seems to have been
installed from the Windows Store, replace the general WindowsApps
directory in search paths with dirname(sys.executable), and also handle
failures with pathlib.resolve on WindowsApps exe files.
This is done with the new cmake subprojects options object
that is similar to the already exisiting configuration data
object. It is consumed by the new `options` kwarg of the
cmake.subproject function.
D lang compilers have an option -release (or similar) which turns off
asserts, contracts, and other runtime type checking. This patch wires
that up to the b_ndebug flag.
Fixes#7082
Ideally we wouldn't need to have the default dict here and could just
rely on it being set as soon as project is called. There is a corner
case exercised by test case common/35 run program, which is that if a
FeatureNew or FeatureDeprecated is called to generate the meson version
it will be unset, to work around this I've changed the type from a dict
to a default dict with '' as the default value.
A better fix would probably be to store all of the
FeatureNew/FeatureDeprecated checks until the end, then evaluate them,
but for now this results in no loss of functionality, only more
functionality, even if it isn't prefect.
This gives the version that the feature was deprecated in, and doesn't
print the warning if the project supports versions of meson in which the
project wasn't deprecated.
The implementation of this function has changed enough that the name
doesn't really reflect what it actually does. It basically returns true
unless you're cross compiling, need and exe_wrapper, and don't have one.
The original function remains but is marked as deprecated.
This makes one small change the meson source language, which is that it
defines that can_run_host_binaries will return true in build == host
compilation, which was the behavior that already existed. Previously
this was undefined in build == host compilation.
Gtest can output junit results with a command line switch. We can parse
this to get more detailed results than the returncode, and put those in
our own Junit output. We basically just throw away the top level
'testsuites' object, then fixup the names of the tests, and shove that
into our junit.
Cosmetic tweak to the error message for incdir() with an absolute path.
Don't split the message in the middle of a sentence at a point which may
or may not correspond to the terminal width.
For the sake of a consistent error message (irrespective of if 'valac' is
present or not), check if the 'c' language is present if we are adding
'vala' before (rather than after) we do compiler detection.
Generally, we'd want to use str() rather than repr() in error messages
anyhow, as that explicitly gives something designed to be read by
humans.
Sometimes {!r} is being used as a shortcut to avoid writing the quotes
in '{!s}'.
Unfortunately, these things aren't quite the same, as the repr of a
string containing '\' (the path separator on Windows) will have those
escaped.
We don't have a good string representation to use for the arbitrary
internal object used as an argument for install_data() when it's neither
a string nor file (which doesn't lead to a good error message), so drop
that for the moment.
This adds support for Files, CustomTarget, Indexs of CustomTargets,
ConfigureFiles, ExternalPrograms, and Executables.

* dependency: log cached or skipped dependencies with reference to modules
If the dependency is a special dependency which takes modules, the
modules get cached separately and probably reference different
pkg-config files. It's very plausible that we have multiple
dependencies, using different modules. For example:
Run-time dependency qt5 (modules: Core) found: YES 5.14.2 (pkg-config)
Dependency qt5 skipped: feature gui disabled
Obviously this makes no sense, because of course we found qt5 and even
used it. The second line is a lot more readable if it shows this:
Dependency qt5 (modules: Widgets) skipped: feature gui disabled
Similar confusion abounds in the case where a module is found in the
cache -- which module, exactly, has been found here:
Dependency qt5 found: YES 5.14.2 (cached)
Rewrite the dependency function to *consistently* pass around (and use!)
the display_name even in cases where we know it isn't anonymous (this is
just more correct anyway), and make it serve a dual purpose by also
appending the list of modules just like we do for pretty-printing that a
dependency has just been found for the first time.
* fixup! dependency: log cached or skipped dependencies with reference to modules
pointlessly cast modules to str, as they cannot be anything else. But we
want to fail later on, with something more friendly than a stacktrace.
boost/wx have special exceptions for people passing an integer there.
- ExternalProgramHolder has path() method while CustomTargetHolder and
BuildTargetHolder have full_path().
- The returned ExternalProgramHolder's path() method was broken, because
build.Executable object has no get_path() method, it needs the
backend.
- find_program('overridden_prog', version : '>=1.0') was broken because
it needs to execute the exe that is not yet built. Now assume the
program has the (sub)project version.
- If the version check fails, interpreter uses
ExternalProgramHolder.get_name() for the error message but
build.Executable does not implement get_name() method.
A current rather untyped storage of options is one of the things that
contributes to the options code being so complex. This takes a small
step in synching down by storing the compiler options in dicts per
language.
Future work might be replacing the langauge strings with an enum, and
defaultdict with a custom struct, just like `PerMachine` and
`MachineChoice`.
Currently, looking for a nonexisting program using find_program() will
return an NonExistingExternalProgram instace with the default name
'nonexistingprogram'. Let's store the target program's name in it, so it
can be printed if needed.

Currently, the error message is printing the object itself. Showing the
program's name is better.
