#51364: py34-parsing @ 2.1.2 fails to build
-------------------------+--------------------------------

-------------------------+--------------------------------
The python3.x build of py-parsing @2.1.2 fails.
Traceback (most recent call last):
File "setup.py", line 9, in <module>

extract_stack
return [(frame_summary.filename, frame_summary.lineno)]
AttributeError: 'tuple' object has no attribute 'filename'
The culprit is found in pyparsing.py:
{{{
# this version is Python 2.x-3.x cross-compatible
'decorator to trim function calls to match the arity of the target'
def _trim_arity(func, maxargs=2):
if func in singleArgBuiltins:
return lambda s,l,t: func(t)
limit = [0]
foundArity = [False]
if PY_3:
def extract_stack():
frame_summary = traceback.extract_stack()[-3]
return [(frame_summary.filename, frame_summary.lineno)]
def extract_tb(tb):
frames = traceback.extract_tb(tb)
frame_summary = frames[-1]
return [(frame_summary.filename, frame_summary.lineno)]
else:
extract_stack = traceback.extract_stack
extract_tb = traceback.extract_tb
}}}
In python3.x 'traceback.extract_stack()' returns a list of quadruples
(filename, line number, function name, text), each of whose elements is
accessed by index.
