Fred Drake	ef8ebd1e74	Make sure that when we invoke callback functions associated with weak ... references, we do not allow any outstanding exceptions "leak" into the callback's execution state. This closes SF bug #478534.	2001-12-10 23:44:54 +00:00
Barry Warsaw	d586756dc5	weakref_repr(), proxy_repr(): Conversion of sprintf() to ... PyOS_snprintf() for buffer overrun avoidance.	2001-11-28 21:01:56 +00:00
Marc-André Lemburg	d4c0a9c59b	Fixes for possible buffer overflows in sprintf() usages.	2001-11-28 11:47:00 +00:00
Jeremy Hylton	996fad315c	Referencable is not a word, so don't use it in an error message <wink>.	2001-10-22 16:31:40 +00:00
Fred Drake	31f4d1fa4b	Remove an unnecessary check for NULL.	2001-10-18 19:21:46 +00:00
Fred Drake	73006d0237	When weakref proxies are involved in binary & ternary slot operations, ... the left-hand operand may not be the proxy in all cases. If it isn't, we end up doing two things: a) unwrapping something that isn't a PyWeakReference (later resulting in a core dump) and b) passing a proxy as the right-hand operand anyway, even though that can't be handled by the actual handler (maybe eventually causing a core dump). This is fixed by always unwrapping all the proxies involved before passing anything to the actual handler.	2001-10-18 18:04:18 +00:00
