Those function are common source of issue when used in a subproject because they
point to the parent project root which is rarely what is expected and is a
violation of subproject isolation.
This means that, in the common case of a simple meson.build which
doesn't contain any 'native: true' targets, we won't require a native
compiler when cross-compiling, without needing any changes in the
meson.build.
Documentation of most methods mentions method arguments enclosed in
parentheses. Two methods are an exception and we fix them here to make
the manual more consistent.
Should be "sources" not "source"

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
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.
- 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.
Refine documentation of the default name_prefix, so people don't get the
impression they can write logic which uses 'lib' as the default, when
they should be defaulting to '[]', to let us take care of the
complexities.
Similar to meson.override_find_program() but overrides the result of the
dependency() function.
Also ensure that dependency() always returns the same result when
looking for the same dependency, this fixes cases where parts of the
project could be using a system library and other parts use the library
provided by a subproject.
As any child of BuildTargetHolder might need the name of the object,
provides a method to get object name.
This is useful in gst-build to display the plugin name and not
the filename.
This is a significant speed-up on Windows because terminals are
slow to print things out.
Speed-up in gst-build on Windows:
```
meson install:
before: 5.1 seconds
after: 4.0 seconds
```
This improves the common case of a simple meson.build which doesn't
contain any 'native: true' targets to not require a native compiler when
cross-compiling, without needing any changes in the meson.build.
v2:
Do it the right way around!
Currently it's just like if all builtin/base/compiler options are
yielding. This patch makes possible to have non-yielding builtin
options. The value in is overriden in this order:
- Value from parent project
- Value from subproject's default_options if set
- Value from subproject() default_options if set
- Value from command line if set
The documentation of "order-only" dependencies is limited and their
various purposes are especially not clear. See issue #6391 for a recent
example, search the internet for many more. So mention the particular
purpose here while making the documentation barely longer.
this can be useful for if/elif where linker behaviors must be
considered.
For example, clang with "link" vs gcc with "ld.bfd" etc.

This default behavior can have surprising and time-consuming outcomes.
I was wondering why certain tests using several external, fixed libraries
would fail only with Meson and not with CMake or manual runs.
It turned out mtest.py enables MALLOC_PERTURB_ by default, which is
surprising--a topic for another Issue/PR.
At least, this surprising default is documented with workarounds.
