             Summary: PBX_Lua: after asterisk startup module is loaded, but dialplan not available
                 Key: ASTERISK-23818
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-23818
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
    Affects Versions: 11.7.0
         Environment: Ubuntu 14.04 64bit

Linux x201 3.13.0-27-generic #50-Ubuntu SMP Thu May 15 18:06:16 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

            Reporter: Dennis Guse
            Severity: Minor


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).

How to reproduce the problem.

- Module is really loaded and thus fails:
#asterisk -rc "module load pbx_lua" 

- Let the started Asterisk reload pbx_lua
# sudo asterisk -rxvvvvv
> module reload pbx_lua.so

----
Investigation:

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

static int reload(void)
{
	return load_or_reload_lua_stuff();
}

static int load_module(void)
{
	int res;

	if ((res = load_or_reload_lua_stuff()))
		return res;

	if (ast_register_switch(&lua_switch)) {
		ast_log(LOG_ERROR, "Unable to register LUA PBX switch\n");
		return AST_MODULE_LOAD_DECLINE;
	}

	return AST_MODULE_LOAD_SUCCESS;
}

----

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