Move the PY_XXX = true|false variable definitions meant to be preset by including makefiles to the top of py-defs.mk to make the structure of the file clearer.
Add PY_INSTALL_INIT_PY ?= true to py-defs.mk. If set to false, a Python module will not try to attempt installing an existing / generated __init__.py. This is useful when installing into an exiting directory with an existing __init__.py.
Remove PY_PREREQ_BUILD and PY_PREREQ_BUILD_DIRS from py-defs.mk: Apparently they're not used anywhere, and are costly in terms of directory startup time.
This commit aims at improving speed by using better caching.
- Makefile, cache.mk: Split .cache.mk up
To allow caching of runtime path variables which are
project-specific, split .cache.mk up in .cache-project.mk and
.cache-projects.mk
- ldlibpath.mk: Cache ldlibpath, exepath and pythonpath
Place the output of $(call proj_query ldlibpath), $(call
proj_query, exepath) and $(call proj_query pythonpath) in
JW_PKG_LD_LIBRARY_PATH, JW_PKG_EXE_PATH, and JW_PKG_PYTHON_PATH
respectively, and cache the variables in make/.project-cache.mk.
- cache.mk: Use = instead of :=
Recursively expanded variables are nearly as fast as := variables
if the assigned value is a fixed string. And sometimes it's not,
rightly so, because variables get assigned below, as with
JW_PKG_XXX for instance.
- cache.mk: Use $(TOPDIR) as variable values
Replace absolute references to project's topdir by $(TOPDIR) with
sed. As soon as the project queries produce absolute paths, they
will be transformed into relative paths which allow the code base
to be moved to a different location and still remain functional
without a rebuild.
Support the Makefile variables PY_INSTALL, PY_INSTALL_REG, PY_INSTALL_PYC, all defaulting to true. They can be set to false to stop installation of whatever file type is undesired in the target. A common use case for this are __init__.cpython-313.pyc, provided by a package the installing package depends on. The prerequisite package might already provide these files for common directories.
The current globbing pattern for filling the PYTHON variable doesn't account for the fact that /usr/bin/python3.X might have more than one digit for X, fix that
This commit adds support for static typechecking with mypy.
Notable additions:
- A new target "check" which does the type checking
- Py-mods.mk, meant to be included from a directory containing python modules
in subdirectories, but not being a python module itself. It makes the all
target depend on check only if PY_RUN_CHECK_AFTER_BUILD is defined and
true. That's because pypy is under heavy development, and the Ubuntu 18.04
version is too old to work for lots of the code.
PY_SITE_PACKAGES_PATH is set to the first element site.getsitepackages(), which (correctly, but in this case undesirably) is below /usr/local. Use the first path which is not.
Predefined PY_INSTALL_DIR was ignored prior to this commit, which shuffles the py-defs.mk variables around considerably. Still some temporary variables unnecessarily defined with ?=, but some testing would be good prior to further changes.
This commit flips some more switches from Python 2 to Python 3 in makefiles and Python code. Build runs through, but it's still likely to break things.
