[HACKERS] about error handling mechanism
Hi! I was looking into the postgres error handling mechanism, and the documentation states that the present mechanism is primitive. I quote whenever the parser, planner/optimizer or executor decide that a statement cannot be processed any longer, the whole transaction gets aborted and the system jumps back into the main loop to get the next command from the client application. Also, it states it is possible that the database server is in an inconsistent state at this point so returning to the upper executor or issuing more commands might corrupt the whole database Since postgres aborts the transaction compeletely, why would it be ever left in an inconsistant state in such an event? Also , I want to get someone's help about the mechanism about how it works. Could someone help me? thanks -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
[HACKERS] arithmetic about inet
I got some point from others.I already red and debug network.c . Now I now the basic logic behind that. But still I'm confused by arithmetic. I find some comments on that , I need some one's help. /* * int * bitncmp(l, r, n) * compare bit masks l and r, for n bits. * return: * -1, 1, or 0 in the libc tradition. * note: * network byte order assumed. this means 192.5.5.240/28 has * 0x in its fourth octet. * author: * Paul Vixie (ISC), June 1996 */ Why we finish it in this way. Can you help me?
[HACKERS] arithmetic about inet
Hi Guys: I just do some research on ip address storage and comparing. I found pgsql already fixed that issue. I want to get some point from your guys about how this work. Could you give me some data about that . Also I'm interesting in pgsql . Could you give me some suggestion about how to hack pgsql. Thank.
