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> +[ Andrey Smirnov: ported to Python 3.6 ] +Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> +--- + Makefile.pre.in | 6 +++++- + configure.ac | 2 ++ + setup.py | 6 +++++- + 3 files changed, 12 insertions(+), 2 deletions(-) + +diff --git a/Makefile.pre.in b/Makefile.pre.in +index b78a765..0e06ddb 100644 +--- a/Makefile.pre.in ++++ b/Makefile.pre.in +@@ -188,6 +188,8 @@ FILEMODE= 644 + # configure script arguments + CONFIG_ARGS= @CONFIG_ARGS@ + ++# disabled extensions ++DISABLED_EXTENSIONS= @DISABLED_EXTENSIONS@ + + # Subdirectories with code + SRCDIRS= @SRCDIRS@ +@@ -606,6 +608,7 @@ sharedmods: $(BUILDPYTHON) pybuilddir.txt Modules/_math.o + esac; \ + $(RUNSHARED) CC='$(CC)' LDSHARED='$(BLDSHARED)' OPT='$(OPT)' \ + _TCLTK_INCLUDES='$(TCLTK_INCLUDES)' _TCLTK_LIBS='$(TCLTK_LIBS)' \ ++ DISABLED_EXTENSIONS="$(DISABLED_EXTENSIONS)" \ + $(PYTHON_FOR_BUILD) $(srcdir)/setup.py $$quiet build + + +@@ -1433,7 +1436,8 @@ libainstall: all python-config + # Install the dynamically loadable modules + # This goes into $(exec_prefix) + sharedinstall: sharedmods +- $(RUNSHARED) $(PYTHON_FOR_BUILD) $(srcdir)/setup.py install \ ++ $(RUNSHARED) DISABLED_EXTENSIONS="$(DISABLED_EXTENSIONS)" \ ++ $(PYTHON_FOR_BUILD) $(srcdir)/setup.py install \ + --prefix=$(prefix) \ + --install-scripts=$(BINDIR) \ + --install-platlib=$(DESTSHARED) \ +diff --git a/configure.ac b/configure.ac +index 250b23b..fc4e71a 100644 +--- a/configure.ac ++++ b/configure.ac +@@ -2779,6 +2779,8 @@ LIBS="$withval $LIBS" + + PKG_PROG_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, +diff --git a/setup.py b/setup.py +index f04bf22..c5bce21 100644 +--- a/setup.py ++++ b/setup.py +@@ -43,7 +43,11 @@ host_platform = get_platform() + COMPILED_WITH_PYDEBUG = ('--with-pydebug' in sysconfig.get_config_var("CONFIG_ARGS")) + + # 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 +-- +2.9.3 + |
