I am developing FreeSwitch Javascript capability to emulate some functionality that is currently provided by a Dialogic based proprietary system running on Microsoft Windows, originally using ISDN interfaces and then ported to Sip based VoIP capability.<br>
This system uses external post-processing code that processes "event" type data for billing and other purposes and I need to provide equivalent event data.<br>
As part of this effort, I need a counter that is guarantied unique when there is a possibility that multiple calls may access the counter. The proprietary code, this unique counter is provided by using InterlockedIncrement().<br>
<br>
Looking at the available JavaScript code, it appears that using getGlobalVariable() and setGlobalVariable() as described in the SetGlobalVar Wiki page would allow me to do this as long as I was willing to allow holes in the count.<br>
<br>
However, I decided to look at the code to see exactly what was being done to implement this. I found was that there was no code at all to implement the 3rd optional parameter.<br>
<br>
I would like to implement this capability but extend the capability to truly provide a unique counter. To accomplish this, support must be provided by the switch core.<br>
<br>
I would like to provide a new routine into switch_core.c:<br>
<Following is the text for switch_core.h><br>
/*!<br>
\brief Conditionally add a global variable to the core<br>
\param varname the name of the variable<br>
\param value the value of the variable<br>
\param val2 the value of the variable to verify against<br>
\ If the global did not exist and val2=="", add global with value, return true<br>
\ If the global exists with the value of val2, replace it, return true<br>
\ If the global exists with a value other than val2, return false<br>
*/<br>
SWITCH_DECLARE(switch_bool_t) switch_core_set_var_conditional(_In_z_ const char *varname, _In_opt_z_ const char *value, _In_opt_z_ const char *val2);<br>
<br>
Then the code in mod_spidermonkey.c can be modified to use this new switch core capability.<br>
<br>
Note: I have implemented this in my local version and have tested it.<br>
