From 7c1ec8c8e763f9ab59f0de3ee25d2cd325d7480e Mon Sep 17 00:00:00 2001 From: Neels Hofmeyr Date: Thu, 2 Mar 2017 14:32:52 +0100 Subject: ctrl_type_vals: explicitly terminate Don't use CTRL_TYPE_UNKNOWN as value_string[] terminator, use an explicit, more obvious { 0, NULL } termination. Set an explicit string for CTRL_TYPE_UNKNOWN. No other value_string[]s to date have such a "hidden" terminator. BTW, a { 0, "string" } item is not a terminator, only { 0, NULL } is, so we can set a string for CTRL_TYPE_UNKNOWN == 0. Also, having a string value for CTRL_TYPE_UNKNOWN is not harmful because all code paths explicitly check for the CTRL_TYPE_*s that are valid. Adjust the test expectation. From the ctrl_type_vals enum, remove the = 0, because it is implicitly 0 anyway. One motivation to press this fixup: I am trying to add a script that checks whether all value_string[]s are terminated to our jenkins jobs, and to find that this one is terminated, it would need to interpret the CTRL_TYPE_UNKNOWN constant, which would make things far more complex. At this point, all of the value_string[]s have an explicit termination, and I would like to enforce this from now on -- for readable code and to not spend more time on the validator. The patch adding ctrl_type_vals (Icd4e96dd9f00876cb70b43cfcf42ab4f10311b28) was accepted by another reviewer before I could reconfirm my -1, so this is a fixup to enable the termination checking script patches.
