From c111d9fbbd1217147c3e1ee3374a0c87a8b94c93 Mon Sep 17 00:00:00 2001 From: "Gregory P. Smith" Date: Sun, 9 Sep 2007 23:55:55 +0000 Subject: merge this from trunk: r58067 | gregory.p.smith | 2007-09-09 16:36:46 -0700 (Sun, 09 Sep 2007) | 22 lin es Change socket.error to inherit from IOError rather than being a stand alone class. This addresses the primary concern in http://bugs.python.org/issue1706815 python-dev discussion here: http://mail.python.org/pipermail/python-dev/2007-July/073749.html I chose IOError rather than EnvironmentError as the base class since socket objects are often used as transparent duck typed file objects in code already prepared to deal with IOError exceptions. also a minor fix: urllib2 - fix a couple places where IOError was raised rather than URLError. for better or worse, URLError already inherits from IOError so this won't break any existing code. test_urllib2net - replace bad ftp urls. --- Doc/library/exceptions.rst | 3 +++ Doc/library/socket.rst | 3 +++ Doc/whatsnew/2.6.rst | 3 ++- Lib/test/test_urllib2net.py | 16 +++++++--------- Lib/urllib2.py | 4 ++-- Modules/socketmodule.c | 3 ++- 6 files changed, 19 insertions(+), 13 deletions(-) diff --git a/Doc/library/exceptions.rst b/Doc/library/exceptions.rst index 9bc597e..c35d7d4 100644 --- a/Doc/library/exceptions.rst +++ b/Doc/library/exceptions.rst @@ -147,6 +147,9 @@ The following exceptions are the exceptions that are actually raised.
