for those who wondered why pyxpcom has trouble looking up some trivial
error codes such as NS_ERROR_FILE_NOT_FOUND:
this is a problem related to signed ints and longs being treated
differently in python.
here is a fixed version of the exception class that properly looks up
and returns errors:
# The standard XPCOM exception object.
# Instances of this class are raised by the XPCOM extension module.
class Exception(exceptions.Exception):
def __init__(self, errno, message = None):
assert int(errno) == errno, "The errno param must be an integer"
self.errno = errno
if self.errno < 0: # fix signed int problem
self.errno = 0x100000000 + self.errno
self.message = message
exceptions.Exception.__init__(self, errno)
def __str__(self):
if not hr_map:
import nsError
for name, val in nsError.__dict__.items():
if type(val) in (long,int):
hr_map[val] = name
message = self.message
if message is None:
message = hr_map.get(self.errno)
if message is None:
message = ""
return "0x%x (%s)" % (self.errno, message)
