Since `build_always` also adds a target to the set of default targets,
this option is marked deprecated in favour of the new option
`build_always_stale`.
`build_always_stale` *only* marks the target to be always considered out
of date, but does *not* add it to the set of default targets.
The old behaviour can still be achieved by combining
`build_always_stale` with `build_by_default`.

On macOS, we set the install_name for built libraries to
@rpath/libfoo.dylib, and when linking to the library, we set the RPATH
to its path in the build directory. This allows all built binaries to
be run as-is from the build directory (uninstalled).
However, on install, we have to strip all the RPATHs because they
point to the build directory, and we change the install_name of all
built libraries to the absolute path to the library. This causes the
install name in binaries to be out of date.
We now change that install name to point to the absolute path to each
built library after installation.

With this, the default workflow on macOS matches what everyone seems
to do, including Autotools and CMake. The next step is providing a way
for build files to override the install_name that is used after
installation for use with, f.ex., private libraries when combined with
the install_rpath: kwarg on targets.
When the exe runner is `wine` or `wine32` or `wine64`, etc.
This allows people to run tests with wine.
Note that you also have to set WINEPATH to point to your custom
prefix(es) if your tests use external dependencies.

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.
This option controls the permissions of installed files (except for
those specified explicitly using install_mode option, e.g. in
install_data rules.)
An install-umask of 022 will install all binaries, directories and
executable files with mode rwxr-xr-x, while all data and non-executable
files will be installed with mode rw-r--r--.
Setting install-umask to the string 'preserve' will disable this
feature, keeping the permissions of installed files same as the files in
the build tree (or source tree for install_data and install_subdir.)
Note that, in this case, the umask used when building and that used when
checking out the source tree will leak into the install tree.
Keep the default as 'preserve', to show that no behavior is changed and
all tests keep passing unchanged.
Tested: ./run_tests.py
Fixes the bug with flat layout and identical target names in subprojects.
Without this change directories are not created with subproject prefix
and they can collide.
Remove dead makedirs code in Backend.__init__(), during initialization
of backend build.targets is empty. Create output directories in
Vs2010Backend.generate_projects() instead.
Also use double blank line in run_unittests.py according to
https://www.python.org/dev/peps/pep-0008/#blank-lines.
Currently we try both C and C++ when determining which PCH files to
include. The problem with this approach is that if there are no C or C++
files (only headers) and the target has both C and C++ sources then the
PCHs will be passed to the wrong compiler.
The solution is less code, we already have the compiler, the compiler
knows what language it is, so we don't need to walk both C and C++.
Fixes#3068
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.
/WHOLEARCHIVE must go to AdditionalOptions, not AdditionalDependencies
and we must add a project reference to trick msbuild/visual studio into
building a target that is built from only libraries linked in via
/WHOLEARCHIVE.
This allows a CustomTarget to be indexed, and the resulting indexed
value (a CustomTargetIndex type), to be used as a source in other
targets. This will confer a dependency on the original target, but only
inserts the source file returning by index the original target's
outputs. This can allow a CustomTarget that creates both a header and a
code file to have it's outputs split, for example.
Fixes#1470
Add a boolean 'implib' kwarg to executable(). If true, it is permitted to
use the returned build target object in link_with:
On platforms where this makes sense (e.g. Windows), an implib is generated
for the executable and used when linking. Otherwise, it has no effect.
(Rather than checking if it is a StaticLibrary or SharedLibary, BuildTarget
subclasses gain the is_linkable_target method to test if they can appear in
link_with:)
Also install any executable implib in a similar way to a shared library
implib, i.e. placing the implib in the appropriate place
Add tests of:
- a shared_module containing a reference to a symbol which is known (at link
time) to be provided by the executable
- trying to link with non-implib executables (should fail)
- installing the implib
(This last one needs a little enhancement of the installed file checking as
this is the first install test we have which needs to work with either
MSVC-style or GCC-style implib filenames)
