[OpenSIPS-Users] [2.2/devel] Heads up, major changes

[Bogdan-Andrei Iancu]

Hi all,

This is a heads up regarding some latest changes over OpenSIPS 2.2 / 
devel branch, changes that do impact your scripts :

1) *"fork" option replaced wit**h "debug_mode"*
The fork/don't fork option made no sense anymore in the new OpenSIPS 
architecture (with async reactor). Even more, the so called "fork" was 
related only to SIP workers (even with fork=no, opensips was forking 
timer process, per-module processes); not to mention the fork=no 
limitation to only one UDP interface. Shortly, the "fork" option became 
outdated, causing more problem (coding and experience), rather than 
something useful.
"debug_mode" option was introduce as better way to switch on and off a 
fast way to debug your opensips. Upon enabling the "debug_mode", 
opensips will automatically force:
      - staying in foreground (do not detach from console)
      - set logging level to 4 (debug)
      - set logging to standard error
      - enable core dumping
      - set UDP worker processes to 2
      - set TCP worker processes to 2

2) *"debug" option replaced with "log_level"*
The global parameter "debug" was renamed "log_level" for a more accurate 
description of the setting. The values and the behavior were kept 
exactly as before. Of course the MI function "debug" was renamed to 
"log_level".

3) *"set_debug()" function replaced with "$log_level" variable*
Th3e $log_level with behave upon writing exactly as old set_debug() - a 
new logging level will be set (as number) or the log level will be reset 
(for a NULL input). Even more, the variable will accept to be populated 
from other variables/transformations. Upon reading, the current per 
process logging level will be returned.
     Ex :
         $avp(custom_log_level) = 4;
         xlog("Current logging level is $log_level\n");
         $log_level = $avp(custom_log_level); /* switch to debug level */
         xlog("Running in debug level ($log_level) now\n");
$log_level = NULL;
    xlog("Resetting back to logging level $log_level\n");


Any feedback or reports are welcome !
