Bug ID: 212122
Summary: getaddrinfo doesn't implement sort rule 10
deterministically
Product: Base System
Version: CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Many People
Priority: ---
Component: bin
Assignee: [email protected]
Reporter: [email protected]
The formal behavior of qsort is unstable with regard to objects that are equal.
Unfortunately, the standard requires that otherwise equal objects remain in
the order supplied by the DNS server. The present code attempts to deal with
this by returning -1 for objects that are equal (i.e., returns that the first
parameter is less then the second parameter). Unfortunately, the qsort API
does not state that the first parameter passed in is in any particular position
in the list.
Assuming I can get it uploaded, the patch I have for it will be against
Revision 304034.
Again, while this affects a lot or people, I don't think many will notice.
It's been this way for years and I only just noticed...
