[asterisk-bugs] [JIRA] (ASTERISK-28422) Memory Leak in Confbridge menu

[Ted G (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-28422?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=249041#comment-249041 ] 

Ted G commented on ASTERISK-28422:
----------------------------------

Clear seems to work, however bridge and user have to be cleared as well.

I simply don't agree with how this works.  Ive never seen an environment where setting something results in an append instead of an overwrite.  But thats my opinion.

There is still a small leak though as a hangup does not completely free all that confbridge/conf_config_parser.c is using although its very negligible.

>      Security Level: None
>          Components: Applications/app_confbridge

>         Environment: Debian GNU/Linux 9.8 (stretch)

> When users on my system join a conference bridge some variables are being set dynamically like so:
> {noformat}
> ast_setvar("CONFBRIDGE(bridge,record_file)", recfn);
> ast_setvar("CONFBRIDGE(user,startmuted)", mute ? "yes" : "no");
> ast_setvar("CONFBRIDGE(user,music_on_hold_class)", music ? music : "default");
> ast_setvar("CONFBRIDGE(user,music_on_hold_when_empty)", music ? "yes" : "no");
> {noformat}
> All of this works fine, however users are quite often taken off the bridge to change these settings so every time they enter the bridge these settings are applied based on whatever configuration they are using.
> My assumption is that once the channel is destroyed (upon Hangup) these settings vanish.  I am not using confbridge.conf at all.
> My assumption appears false however as memory usage continues to grow day by day:
> {noformat}
>    54616804 bytes in      15255 allocations in file confbridge/conf_config_parser.c
> {noformat}
