[Bug 1378888] Re: OptionParser on PPC64LE does not split args correctly

[Breno Leitão]

Tony,

what is the contect of /tmp/REIX?

I am trying to reproduce it on 14.10, using a simple text file at
/tmp/REIX and I got:

ubuntu at ubuntu:~/avro/avro/trunk/lang/py/build/scripts-2.7$ avro cat /tmp/REIX --fields 'first,last'
panic: ord() expected a character, but string of length 0 found

Title:
  OptionParser on PPC64LE does not split args correctly

Status in “python2.7” package in Ubuntu:
  New

Bug description:
  The issue appears on PPC64 LE.
  It is OK on (Ubuntu) x86_64.
  Version of Python is 2.7.6 on both systems.
  The issue is demonstrated while running AVRO Python tests (in lang/py : ant test).

  
  - On Ubuntu / PPC64 LE :

  $ pwd
  ..../lang/py
  $ export PYTHONPATH=./build/src
  $ /home/tony/AVRO/avro-FromFreshIBMSOEGitHub/lang/py/build/test/../scripts/avro cat /tmp/REIX --fields 'first, last'
  {"first": "daffy"}
  {"first": "bugs"}
  {"first": "tweety"}
  {"first": "road"}
  {"first": "wile"}
  {"first": "pepe"}
  {"first": "foghorn"}
  Usage: avro cat|write [options] FILE [FILE...]

  avro: error: Can't open last - [Errno 2] No such file or directory: 'last'
  $ echo $?
  2

  The issue is that 'first, last' is not parsed correctly. The white
  space between "," and "last" is parsed in a way that makes "last" been
  interpreted as a "FILE" instead of an option.

  
  Without the white space, that works fine:

  $ /home/tony/AVRO/avro-FromFreshIBMSOEGitHub/lang/py/build/test/../scripts/avro cat /tmp/REIX --fields 'first,last'
  {"last": "duck", "first": "daffy"}
  {"last": "bunny", "first": "bugs"}
  {"last": "", "first": "tweety"}
  {"last": "runner", "first": "road"}
  {"last": "e", "first": "wile"}
  {"last": "le pew", "first": "pepe"}
  {"last": "leghorn", "first": "foghorn"}
  $ echo $?
  0

  
  - On Ubuntu / x86_64, both 'first, last' and 'first,last' are OK:

  $ pwd
  ..../lang/py
  $ export PYTHONPATH=./build/src
  $ build/test/../scripts/avro cat /tmp/REIX --fields 'first, last'
  {"last": "duck", "first": "daffy"}
  {"last": "bunny", "first": "bugs"}
  {"last": "", "first": "tweety"}
  {"last": "runner", "first": "road"}
  {"last": "e", "first": "wile"}
  {"last": "le pew", "first": "pepe"}
  {"last": "leghorn", "first": "foghorn"}
  $ echo $?
  0

  
  Source code of: /home/tony/AVRO/avro-FromFreshIBMSOEGitHub/lang/py/build/test/../scripts/avro  is:

  def main(argv=None):
      import sys
      from optparse import OptionParser, OptionGroup

      argv = argv or sys.argv

      parser = OptionParser(description="Display/write for Avro files",
                        version="1.7.4",
                        usage="usage: %prog cat|write [options] FILE [FILE...]")
  ....

  So, OptionParser() does not work on PPC64 like it does on x86_64.
