If I use the command line "snmpset" to set a bunch of variables, I am (nearly*) guaranteed that either they all happen or none of them do. So if I set foo to 3 and bar to 7, handle_foo() will get a RESERVE1, RESERVE2, etc. handle_bar will get a RESERVE1, RESERVE2, etc. If neither returns any error, net-snmp assumes that all will work and calls handle_foo() with a COMMIT and calls handle_bar() with COMMIT. If there is a problem, the UNDO and FREE (or FREE and UNDO) are called and no COMMITs are called. Which means if two different snmpset's are done, one will get in first and either backout or succeed before the second gets a chance to happen. Correct? If so, then I conclude I am safe. You pointed out the case of two different sets of the same variable in a single snmpset might interfere. Well, that is perverse and I think not a case I need to handle "correctly" (because it is poorly defined what would be correct), but merely not crash or corrupt. Right? Thanks, -kb, the Kent who thinks he will add a check that he is not reentered and if he is, error out in the RESERVE1 stage to kill the whole transaction. * "nearly"? Well, if I error in the COMMIT, what can net-snmp do? If I (and every other handler) never errors out of the COMMIT, then the guarantee can be met. -- Kent Borg Software Engineer CSR Technology, Inc.
