Subject API for detecting first config run
Date Fri, 12 Nov 2010 18:47:29 GMT

it is common procedure for modules to detect the first configuration 
run at httpd startup by looking for some userdata in the process pool. 
If the userdata is not set, they set it and then skip some 
initialization that should not be done during the first config run.

But this logic is broken: If a LoadModule statement is added while 
httpd is running, and httpd is then gracefully restarted, the module 
will be loaded but assume that this is the startup configuration 
phase. It won't initialize itself fully and will work correctly only 
after the second graceful restart. This can be very confusing for 

Therefore I intend to add some API like ap_in_initial_configuration() 
which will tell modules reliably if httpd is currently starting up or 
not. Does anyone see a problem with this that I have missed?
