<pre style="margin-left: 2em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">In Asterisk, we have a handy shortcut that prevents you from having to do
if (!foo || !*foo). Instead, you can call ast_strlen_zero(foo) for the same functionality.
So in this case, you can just call
if (ast_strlen_zero(ac) && ast_strlen_zero(bc)) {
return 0;

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This patch fixes a bug report where restarting Asterisk repeatedly would cause a crash due to accidentally deleting extensions that were still referenced in the context's root_table. This occurred due to confusion over matching or not matching extensions based on callerid, which is also being cleared up via an enum'd third state.
There are two values in an extension entry: matchcid which says whether cid should be matched, and cidmatch which is the string value to match. The matchcid value was previously non-zero when cidmatch was signficant. This is important since a null length callerid match must be kept distinct from a match-anything condition.
This patch adds an enum to define the AST_EXT_MATCHCID_OFF (0) or AST_EXT_MATCHCID_ON (1) behaviors, and adds AST_EXT_MATCHCID_ANY (2) which allows matching to both exten->matchcid=0 and exten->matchcid=1 cases. For example, all exten's with the same exten (number) can be deleted with ANY, but when looking for a dialplan match it must match to matchcid, and if set to ON, further match cidmatch.
The logic to match extensions has been reworked to implement these three types, and then matchcid values updated to use the enum for clarity.
The most significant change is in ast_context_remove_extension_callerid2() where after removing extensions from the hashtable, the deletion would destroy the extensions. This was deleting exten's that didn't have matchcid set but matched a null cidmatch, where they hadn't been removed from the hashtable.
- (!callerid || !matchcallerid || (matchcallerid && !strcmp(peer->cidmatch, callerid))) &&
+ (!callerid || (!matchcallerid && !peer->matchcid) || (matchcallerid && peer->matchcid && !strcmp(peer->cidmatch, callerid))) &&
