Guido van Rossum 433892021e Added doc strings to the exception classes.
Contributed by Blake Winton, but considerably edited.

Guido van Rossum be21d98cee Use repr() on the filename in EnvironmentError.__str__(). This
displays funny characters, like spaces or control characters, more
clearly (one of my pet peeves in error messages).  Also only suppress
the filename if it is None; display it if it is '', since that would
be a genuine (illegal) filename passed in!

Jeremy Hylton ec8c8c2ef2 fix __str__ method of EnvironmentError (base class of IOError): was
using "%d" % errno to print out IOError exceptions -- but urllib.py
raises exceptions where the errno slot in the exception tuple is a
string.

Barry Warsaw 2dfe4de614 Added support for including the filename in IOErrors and OSErrors that
involve a filesystem path.  To that end:

- Changed IOError to EnvironmentError and added a hack which checks
  for arg of len 3.  When constructed with a 3-tuple, the third item
  is the filename and this is squirreled away in the `filename'
  attribute.   However, for in-place unpacking backwards
  compatibility, self.args still only gets the first two items.  Added
  a __str__() which prints the filename if it is given.

- IOError now inherits from EnvironmentError

- New class OSError which also inherits from EnvironmentError and is
  used by the posix module.

Guido van Rossum 45e2fbc2e7 Mass check-in after untabifying all files that need it. 1998-03-26 21:13:24 +00:00
Fred Drake 596db3161c Move the __getitem__() definition from StandardException to Exception.
This allows stuff like this out of the box:

	try:
	    ...
	except socket.error, (code, msg):
	    ...

Barry Warsaw 25131faffe NumberError => ArithmeticError 1997-09-16 21:50:59 +00:00
Guido van Rossum c56ba38350 Two subtle changes:
(1) Introduce Exception as the conceptual root class for all exceptions.

(2) Do less work in __init__(), and more in __str__ (store args
unchanged).

Guido van Rossum e8fd143b7e #Adapt the doc string to reality. 1997-09-08 02:47:46 +00:00
Guido van Rossum f394f56c2b Made the 'info' argument to SyntaxError optional, so phase-2 syntax
errors are handled (these gave ``TypeError: not enough arguments'').

Also changed its __str__() to correct a typo (missing self.) and
return str(self.msg) to ensure the result is always string.

Also changed the default __str__ to simply return str(self.args).

Barry Warsaw 3e613ce79b New file, which is imported by the built-in module when python is
started with the -X option.  This file contains the definitions for
the built-in exception classes.
