By extensions, we +mean part of Python modules that are written in C and therefore +compiled to binary code. + +Therefore, we introduce a small infrastructure that allows to disable +some of those extensions. This can be done inside the configure.ac by +adding values to the DISABLED_EXTENSIONS variable (which is a +word-separated list of extensions). + +The implementation works as follow : + + * configure.ac defines a DISABLED_EXTENSIONS variable, which is + substituted (so that when Makefile.pre is generated from + Makefile.pre.in, the value of the variable is substituted). For + now, this DISABLED_EXTENSIONS variable is empty, later patches will + use it. + + * Makefile.pre.in passes the DISABLED_EXTENSIONS value down to the + variables passed in the environment when calling the setup.py + script that actually builds and installs those extensions. + + * setup.py is modified so that the existing "disabled_module_list" is + filled with those pre-disabled extensions listed in + DISABLED_EXTENSIONS. + +Patch ported to python2.7 by Maxime Ripard <ripard@archos.com>, and +then extended by Thomas Petazzoni +<thomas.petazzoni@free-electrons.com>. + +Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> +--- + Makefile.pre.in | 4 ++++ + configure.ac | 2 ++ + setup.py | 5 ++++- + 3 files changed, 10 insertions(+), 1 deletion(-) + +Index: cpython/Makefile.pre.in +=================================================================== +--- cpython.orig/Makefile.pre.in ++++ cpython/Makefile.pre.in +@@ -155,6 +155,8 @@ + # configure script arguments + CONFIG_ARGS= @CONFIG_ARGS@ + ++# disabled extensions ++DISABLED_EXTENSIONS= @DISABLED_EXTENSIONS@ + + # Subdirectories with code + SRCDIRS= @SRCDIRS@ +@@ -478,6 +480,7 @@ + sharedmods: $(BUILDPYTHON) pybuilddir.txt + $(RUNSHARED) CC='$(CC)' LDSHARED='$(BLDSHARED)' OPT='$(OPT)' \ + CONFIG_ARGS="$(CONFIG_ARGS)" \ ++ DISABLED_EXTENSIONS="$(DISABLED_EXTENSIONS)" \ + $(PYTHON_FOR_BUILD) $(srcdir)/setup.py build + + # Build static library +@@ -1185,6 +1188,7 @@ + # This goes into $(exec_prefix) + sharedinstall: sharedmods + $(RUNSHARED) CONFIG_ARGS="$(CONFIG_ARGS)" \ ++ DISABLED_EXTENSIONS="$(DISABLED_EXTENSIONS)" \ + $(PYTHON_FOR_BUILD) $(srcdir)/setup.py install \ + --prefix=$(prefix) \ + --install-scripts=$(BINDIR) \ +Index: cpython/configure.ac +=================================================================== +--- cpython.orig/configure.ac ++++ cpython/configure.ac +@@ -2175,6 +2175,8 @@ + + AC_PATH_TOOL([PKG_CONFIG], [pkg-config]) + ++AC_SUBST(DISABLED_EXTENSIONS) ++ + # Check for use of the system expat library + AC_MSG_CHECKING(for --with-system-expat) + AC_ARG_WITH(system_expat, +Index: cpython/setup.py +=================================================================== +--- cpython.orig/setup.py ++++ cpython/setup.py +@@ -34,7 +34,10 @@ + sysconfig._CONFIG_VARS.update(os.environ) + + # This global variable is used to hold the list of modules to be disabled. +-disabled_module_list = [] ++try: ++ disabled_module_list = sysconfig.get_config_var("DISABLED_EXTENSIONS").split(" ") ++except KeyError: ++ disabled_module_list = list() + + def add_dir_to_list(dirlist, dir): + """Add the directory 'dir' to the list 'dirlist' (after any relative |
