Libraries that have been linked with link_whole: are internal
implementation details and should never be exposed to the outside
world in either Libs: or Libs.private:
Closes https://github.com/mesonbuild/meson/issues/3509
To maintain backward compatibility we cannot add recursive objects by
default. Print a warning when there are recursive objects to be pulled
and the argument is not set. After a while we'll do pull recursive
objects by default.
- determine_ext_objs: What matters is if extobj.target is a unity build,
not if the target using those objects is a unity build.
- determine_ext_objs: Return one object file per compiler, taking into
account generated sources.
- object_filename_from_source: No need to special-case unity build, it
does the same thing in both code paths.
- check_unity_compatible: For each compiler we must extract either none
or all its sources, taking into account generated sources.
when flattening the chained dependencies of an object, we don't need to
create any new internal dependencies if all the fields to be added to it
are empty.
For projects with a lot of libraries and dependency objects this can lead
to noticeable performance improvements.
fixup
When getting dependencies, we don't need to get the same dependencies and
dependency chains multiple times. If library a depends on x, y and z, and
library b depends on a, then we should not have to iterate through x, y and
z multiple times. Pruning at the stage of scanning the dependencies leads
to significant time savings when running meson
Change the code to store D properties as plain data. Only convert them
to compiler flags in the backend. This also means we can fully parse D
arguments without needing to know the compiler being used.
According to Python documentation[1] dirname and basename
are defined as follows:
os.path.dirname() = os.path.split()[0]
os.path.basename() = os.path.split()[1]
For the purpose of better readability split() is replaced
by appropriate function if only one part of returned tuple
is used.

Currently, we only consider the build depends of the Executable being
run when serializing custom targets. However, this is not always
sufficient, for example if the executable loads modules at runtime or if
the executable is actually a python script that loads a built module.
For these cases, we need to set PATH on Windows correctly or the custom
target will fail to run at build time complaining about missing DLLs.
We can now specify the library type we want to search for, and whether
we want to prefer static libraries over shared ones or the other way
around. This functionality is not exposed to build files yet.
Currently, run_target does not get namespaced for each subproject,
unlike executable and others. This means that two subprojects sharing
the same run_target name cause meson to crash.
Fix this by moving the subproject namespacing logic from the BuildTarget
class to the Target class.
With executable(), if the link_with argument has a string as one of it's
elements, meson ends up throwing an AttributeError exception:
...
File "/home/lyudess/Projects/meson/mesonbuild/build.py", line 868, in link
if not t.is_linkable_target():
AttributeError: 'str' object has no attribute 'is_linkable_target'
Which is not very helpful in figuring out where exactly the project is
trying to link against a string instead of an actual link target. So,
fix this by verifying in BuildTarget.link() that each given target is
actually a Target object and not something else.
Additionally, add a simple test case for this in failing tests. At the
moment, this test case just passes unconditionally due to meson throwing
the AttributeError exception and failing as expected. However, this test
case will be useful eventually if we ever end up making failing tests
more strict about failing gracefully (per advice of QuLogic).
