[asterisk-bugs] [JIRA] (ASTERISK-23818) PBX_Lua: after asterisk startup module is loaded, but dialplan not available

[George Joseph (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-23818?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=219513#comment-219513 ] 

George Joseph commented on ASTERISK-23818:
------------------------------------------

Dennis,
Looks like you installed the Ubuntu 11.7.0 package...
If there's a later package available, have you tried it?
Have you tried compiling from source?
If not and you have the ability to compile from source, can you give that a go with 11.10.2 and see if the problem still exists?

Also, what version of Lua do you have installed.

I'm trying these myself but it'd help if you tried them as well.

thanks.

> The pbx_lua module is loaded successfully on Asterisk startup, but the defined dialplan is not available, resulting in "extension unknown"-messages.
> Using either: module reload pbx_lua.so
> or module unload pbx_lua.so + module load pbx_lua.so
> solves the problem as the configuration is loaded properly.
> modules.conf was not changed (default from Ubuntu maintainers).
> Most probable the configuration done by pbx_lua are overwritten by a component that is loaded later.
> In addition, core reload does not kill the pbx_lua configuration...
> ------
> Hi,
> using the pbx_lua module for almost everything we have found a little annoying "bug". On Asterisk startup the module is loaded - however the configuration (extensions.lua) is not loaded and therefore the lua-defined dialplan is not available. By applying "module reload pbx_lua" the dialplan is loaded as expected (lua dialplan is correct).

> Investigation:
> I took a look into pbx/pbx_lua.c and actually "load" identical to reload + registering the module at Asterisk. Looks neat.

> 		ast_log(LOG_ERROR, "Unable to register LUA PBX switch\n");
> 		return AST_MODULE_LOAD_DECLINE;

> ----
> Could it be that the pbx_lua is loaded to early and the dialplan overwritten by some other dialplan-module that is later loaded?
