Hi Aleks

Thanks for the response. Can you please give me a description of what
ngx_cycle_t and what does it represent? I mean is it a request-response
cycle for each request that comes in? Or is it something else?

Thanks

It represents global data and configuration of a event loop (that
is, whole nginx). New cycle is created on a reconfiguration.

I think it represents the process life cycle.

Hi Maxim,

Thanks for the response. So ngx_cycle_t represents global data and
configuration per event loop. What does ngx_conf_t represent? Is it
related to ngx_conf_t? If so, how?

Thanks

The ngx_conf_t is a structure used during configuration parsing.
It holds various related data, e.g. pointer to a new cycle
structure, current command arguments and so on.

Use the Source, Luke!

Thanks Obi-Wan!

I am going thru the source as we speak and would appreciate a helping
hand!

I can across “NGINX” environment variable in the function
“ngx_add_inherited_sockets”. What does the NGINX variable represent? And
what does the function do?

Appreciate your response.

The “NGINX” environment variable is used to pass listening sockets
from an old master process to a new one during binary upgrade
procedure. (Or, more strictly, it holds numbers of file
descriptors. Sockets remain opened across execve() call, but
new process needs to know their numbers.)

The ngx_add_inherited_sockets() function parses the environment
variable in question and adds sockets to the list of listening
sockets.
