New submission from Stefan Behnel:
The exception handling clauses in framework_find() are weird.
def framework_find(fn, executable_path=None, env=None):
"""
Find a framework using dyld semantics in a very loose manner.
Will take input such as:
Python
Python.framework
Python.framework/Versions/Current
"""
try:
return dyld_find(fn, executable_path=executable_path, env=env)
except ValueError as e:
pass
fmwk_index = fn.rfind('.framework')
if fmwk_index == -1:
fmwk_index = len(fn)
fn += '.framework'
fn = os.path.join(fn, os.path.basename(fn[:fmwk_index]))
try:
return dyld_find(fn, executable_path=executable_path, env=env)
except ValueError:
raise e
My guess is that this is left-over code from Py2.x. Since it doesn't make sense
to catch an exception in the second clause just to re-raise it, I think the
intention was really to re-raise the original exception caught in the first
clause, which no longer works that way in Py3.
The fix would then be to assign the exception to a new variable in the first
except clause and re-raise that in the second.
I found this problem because Cython rejected the module with a compile error
about "e" being undefined in the last line.
