I agree with your comments. This might be useful, though, even if Igor
does make the changes you suggest:
If you're debugging your own code for a module, then all you need to do
is run the installation once for each nginx version / openssl version
etc (including your module's config file). On subsequent tests of your
module, do this:
1) compile your module's code into an object file, making sure that the
path to the ngx headers ($ngx_src_dir/objs) that were generated in the
first compilation is in your include path
2) build a new nginx binary from all the object files that were created
in the first compilation (the list of which you see at the end of the
compilation process - though it might be easiest just to use 'find' to
generate the list automatically), plus the new object file in (1)
This reduces the compilation time to typically less than a second.
