[Buildroot] [PATCH 2/3] python3: Port python2 patches to reduce the interpreter size

[Maxime Ripard]

Some of the python2 patches were left behind when doing the python3
package. This was because the python build system can now autodetect
what packages can be built in the system.

However, some of these patches are actually useful to reduce drastically
the size of the interpreter.

This patch ports the relevant patches to the python3 package, and adds a
new patch to remove the idle3 IDE as well from the interpreter.

Fixes #5696

+Add infrastructure to disable the build of certain extensions
+
+Some of the extensions part of the Python core have dependencies on
+external libraries (sqlite, tk, etc.) or are relatively big and not
+necessarly always useful (CJK codecs for example). 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>.

+Add an option to disable expat

[Buildroot] [PATCH 2/3] python3: Port python2 patches to reduce the interpreter size

[Samuel Martin]

Hi Maxime, all,

2013/1/18 Maxime Ripard <maxime.ripard@free-electrons.com>:
> Some of the python2 patches were left behind when doing the python3
> package. This was because the python build system can now autodetect
> what packages can be built in the system.
>
> However, some of these patches are actually useful to reduce drastically
> the size of the interpreter.
>
> This patch ports the relevant patches to the python3 package, and adds a
> new patch to remove the idle3 IDE as well from the interpreter.
>
> Fixes #5696

No commit message nor sob line here. :-(


BTW, here is a build log: http://code.bulix.org/8rjnsp-82865, in which
the _decimal module fails to be built.

See near the end of the log, it seems the build script of python3 for
the target does some mix up between the host and the target build
config of the package :-/

It also fails if this python patch series is not applied.

After some investigation, here is a patch fixing the build of the
_decimal module:
http://code.bulix.org/p4cp5i-82866

However, source for host-python3 are still used...

  You should remove the -3.3- from the patch names. I know they're there 
in the old package, but this is a good opportunity to get rid of that legacy.

  BTW, do these patches have a chance of getting upstreamed?

  Arnout
