I'm trying to use the http_gunzip module as an example for a filter I am trying to write. I'm particularly interested in the buffer management.
The module has a value in its ctx stuct called last_buf
...
ngx_chain_t **last_out;
...
last_out is set in various places throughout the code. Sometimes to other chains in the ctx, sometimes to newly allocated chains.
But as far as I can tell, none of the code ever uses the value stored in last_out. (It seems to be a write-only variable :-)
Anybody know what I'm missing?
