Re: RFC: Feasibility of a "dynamic module loader" built in to nginx?

Hi,

What might work just as well, and wouldn't suffer the API / performance
issues would be making it easier to compile optional modules into the
source without recompiling the whole Nginx source code.

When I'm doing module development, I just build the object code of the
module I'm writing, and combined it with the pre-compiled object files
of all the other parts of Nginx, thereby typically taking less than a
second to compile (I'm assuming most developers do this too).

It would be nice to be able to have an alternative build script that
makes it easier to do this in a customizable way, allowing the reuse of
existing object code if it's available, compiling it if it's not and
forcing re-compiling if so desired.

It could be set up to accept the normal configuration options, then
automatically work out which object files needed to be re-generated and
which ones could use the pre-compiled versions, and could be extended to
include options and 3rd party modules too.

It wouldn't be particularly difficult to do this, but I'm really busy
with other stuff at the moment. If someone wants to write such a script,
I'll add it to the ngx_devel_kit
(http://github.com/simpl-it/ngx_devel_kit). Otherwise I'll write it at
some point later on, but I can't give any timelines as of yet.

Cheers,

Marcus.
