a 'grep MODULE_PATH' produces zero results (0.9.9 CVS head), which
leads to the thought this one will be unused throughout OPENSSL. To
load a particular engine, its path is specified using -pre
SO_PATH:path-to-engine.so.
So first test would be to see if you still have a working system
without that -pre MODULE_PATH entry in your engine commandline -- if
not, now is the time for some head scratching ;-)
Code-wise, there's several bits 'n pieces in
./README.ENGINE
grep ENGINE_ctrl_cmd_string ./* to find the right(?) spot
and of course, there's the code in ./apps/engine.c (function
util_do_cmds()) but I am quick to admit this is rather limited info.
Haven't interfaced with OpenSSL through Python, so I cannot help you
out there.
You may wish to check the Python interface to check if you can invoke
the OPENSSL ENGINE_ctrl_cmd_string() function from there... :-S
