Bug #54111 [NEW]: read_mib does not return correct response
From:
Operating system: *
PHP version: Irrelevant
Package: SNMP related
Bug Type: Bug
Bug description:read_mib does not return correct response
Description:
------------
snmp_read_mib() returns a boolean depending on success of the read.
Internally, the reab_mib() call returns either NULL or the root of the
mib-tree, depending on succes. This problem here is that read_mib ONLY
returns NULL when the mib-file is not found and not when there is a
parse-error inside the file. In that case it will just return the mib root
tree (which is !null) and thus it will return true back to the php user.
As a sidenote (maybe a different bug): snmp_disable_stderrlog() does not
work 100% for disabling snmp error logging. Net-snmp wants at least 1 type
of log handler active at all times. A simple fix would be to add
snmp_enable_calllog(), so it would use the callback handler for logging
(and since there are no handlers registered, no logging would occur). It
would be nicer though to actually have a callback registered which can
return info back to php level (snmp_[clear|get]_log for instance). The code
for this functional and can be supplied as a patch against php5.3 and the
new OO api in trunk.
Test script:
---------------
var_dump(snmp_read_mib("cannotfindthisfile"));
var_dump(snmp_read_mib("incorrectmibfile"));
Expected result:
----------------
bool(false)
bool(false)
Actual result:
--------------
bool(false)
Warning: snmp_read_mib(): Error while reading MIB file '%s': No such file
or directory in %s on line %d
bool(true)
