Re: Functions run when configuration file is read

[Marco Spinetti]

You can solve your problem in this way:

static int initialize_your_module(apr_pool_t *p, apr_pool_t *plog, 
apr_pool_t *ptemp, server_rec *s) {
   void *data;
   const char *userdata_key = "unique_key_init";
   apr_pool_userdata_get(&data, userdata_key, s->process->pool);
   if (!data) {
       apr_pool_userdata_set((const void *)1, userdata_key,
               apr_pool_cleanup_null, s->process->pool);
       return OK;
   }
   if (init_strutture(s, p) != APR_SUCCESS) {
       return !OK;
   }
   return OK;
}

.....

static void register_hooks(apr_pool_t *p)
{
   ap_hook_post_config(initialize_your_module, NULL, NULL, 
APR_HOOK_MIDDLE);
   .....
}


You have to do all your unique operations in init_strutture function.

  Page 23 of Nick's book talks about the configuration 
being read twice - once while the server is running as
root, to make sure that the configuration is valid, 
then again as Apache goes into operational mode as 
user "nobody" or "apache".  

   Also look into the preconfiguration and postconfiguration
hooks, mentioned on page 66, as well as the monitor hook.
I'm not knowledgeable enough to give you a solid answer, but
this information may provide the "hint" you need to be able
to get it figured out.

working on writing to a file on disk, and reading that in, but that 
is
a 
lot of over head I'd like to avoid.

Thanks though.

   I think I read something about this in Nick's 
book, but I don't recall exactly.  Anyway in case 
someone more knowledgeable than I doesn't reply, remember 
you can of course just set a variable the first time your 
functions are run and then on future invocations you'll 
return immediately if the variable is already set.

Is 
    
there a way to make the functions run only once?  Maybe some
        
variable
    
that can be checked stating that the server is reading the conf 
files,

actually starting the server, or shutting down?

Thanks
