[issue9686] asyncore infinite loop on raise
Terry J. Reedy added the comment: I am closing this because there is no identified, fixable implementation bug in any particular Python module. The fix for the asyncore *design* will be a new, re-designed module. -- nosy: +terry.reedy resolution: - invalid status: open - closed ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue9686 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue9686] asyncore infinite loop on raise
Giampaolo Rodola' g.rod...@gmail.com added the comment: I agree with you that asyncore API model is far from being robust and I've personally seen infinite recursion more than once if certain asyncore methods aren't properly subclassed. What I don't understand is what changes you are proposing and, again, it would be very helpful if you could provide an example code which demonstrates the problems you're complaining about (infinite recursion? broken pipe error? both?). -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue9686 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue9686] asyncore infinite loop on raise
New submission from mmw 0xcafef...@gmail.com: def send(self, data): try: result = self.socket.send(data) return result except socket.error, why: if why.args[0] == EWOULDBLOCK: return 0 elif why.args[0] in (ECONNRESET, ENOTCONN, ESHUTDOWN, ECONNABORTED): self.handle_close() return 0 else: raise for whatever reason the connection could break client side, if you raise an anonymous exception there it's uncatchable, raise on a socket.error or dismiss async chat is a looper. that's the main reason why everybody gets this crazy infinite loop on for instance broken pipe error and the thing never exit, you just raise on your-self other and other again, BTW, you could have the same issue whatever the language, this is a developer bug. -- components: Library (Lib) messages: 114931 nosy: mmw priority: normal severity: normal status: open title: asyncore infinite loop on raise versions: Python 2.7 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue9686 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

mmw 0xcafef...@gmail.com added the comment: First it depends on the socket type but might use a select call, secondable raise on a socket.error, thirdable you could call the close_handle with the message and let the guys if he would like to retry, network connection might be capricious especially for client connected through a wifi network or behind some firewall blocking port the asyncchat is a looper if you don't let him catch the exception you just create an infinite loop, this API needs a stronger model.
