Can not use $bytes_sent in module (complex values)

[Vladimir Shebordaev]

Hi!

The ngx_http_log module uses indexed variables just like the rewrite
module does.

Hope it helps.

I am currently working on a nginx module, that parses user defined

with all variables defined in ngx_http_variables.c (i.e.

$body_bytes_sent). However, variables as $bytes_sent do not exist here

since ngx_http_log_module uses its own variable parsing system. What

thought of the following options, I am not very sure about what is the

best way to go:
>
a) Copy the ngx_http_log_module code in my own module and rename every

single type and function to avoid double definitions. Reuse functions

and types from there.

b) Move the ngx_http_log_module code in my own module directory and

compile it only there. Reuse functions and types from there.

c) Write own variable parsing system, reuse a few snippets from
>
ngx_http_variables and ngx_http_log_module, whatever fits best.

d) Use complex values and try to extend the ngx_http_core_variables
>
array to include $body_bytes_sent and the other missing variables (I
>
don't understand why they are not included here anyway?).
>
e) Any better way to achieve that?

I'd really appreciate your help.
