Daniel Nelson - Jan. 27, 2013, 7:03 p.m.
All,

This is my first buildroot/open source submission. I'd appreciate some feedback.

Python3 changes the behavior of .pyc caching, breaking the PYC-only option in buildroot. The details are in http://www.python.org/dev/peps/pep-3147

I've added a configure flag to Python3, and corresponding logic in buildroot.

Thoughts?

Thanks,

Daniel Nelson

  This message will end up in the git log, but it's not appropriate for 
that. Please create a proper commit message, and make sure it is 
line-wrapped at 80 columns. If you want to give additional comments  that 
should not go into the git log (like the 'this is my first open source 
submission'), add them below the ---.

  Also, we require you to add a Signed-off-by line for yourself. This is 
a short way for you to assert that you are entitled to contribute the 
patch under buildroot's GPL license. See
http://elinux.org/Developer_Certificate_Of_Origin
for more details.


  More minor comments below - but they're just optional, so:
Acked-by: Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be>
  (untested)

(If you repost this patch, with or without the proposed modifications, 
you can add my Acked-by line below your Signed-off-by line.)

  Since there are only two options, an AC_ARG_ENABLE seems more 
appropriate. That also makes the implementation slightly smaller because 
you don't need the STDLIB_CACHE_TYPE, just:

AC_ARG_ENABLE(old-stdlib-cache,
     AS_HELP_STRING(...),
     [
     if [ "$enableval" = "yes" ]; then
        STDLIB_CACHE_FLAGS="-b"
     else
        STDLIB_CACHE_FLAGS=""
     fi
     ],
     [STDLIB_CACHE_FLAGS=""])

  Since we run autoreconf, it's not necessary to patch the configure 
script - it will anyway be overwritten.

I edited the patch file before `git send-email` to include the above text,
so the above text will not be in the commit message. I'll provide a correct
commit message in the next version of the patch.

I will. Thanks.

Acked. I'll make the modifications and resubmit.

  Could you also CC
Maxime Ripard <maxime.ripard@free-electrons.com>

He has done the most work on python3 so he should be able to runtime test 
it (I can do a compile test but that doesn't help much).

  Arnout
