in former times in mmcache.php I saw the actual mm version: 1.3.0 but now it's replaced by: [shm:sysvipc sem:spinlock] can someone tell me how I can see the installed version of mm?
Since Turck MMCache version 2.3.13 it is not use libmm. Now it has its own shared memory abstraction layer. See files mm.h and mm.c. from mmcache distribution.
that means that I can remove the MM shared memory library from engelschall?
If it is not used by other programms, you can.
Some PHP builds use libmm for mm session handler.
wow turck mmcache is amazing ;)
