 26 Jul 2007, Stefan Ritt, Info, Change of pointer type in mvmestd.h
|
I had to change the pointer type of mvme_read and mvme_write to (void *) instead
to (mvme_locaddr_t *) to avoid warnings under 64-bit linux. Please adjust your
VME drivers if necessary.

06 Sep 2007, Stefan Ritt, Info, Introduction of MIDAS_MAX_EVENT_SIZE
|
We had the problem that different experiments used different MAX_EVENT_SIZE
values (the MEG experiment actually 10 MB!). If each experiment changes the
value in midas.h and accidentally commits it, other experiments are affected.

This allows proxy access to mhttpd via an apache server for example, which might

|
Most likely you changed the maximal event size in midas.h, but you did not re-compile [B]all[/B] programs. The maximal event size goes into the size of
the shared memory buffer, so all participating programs have to have the same setting, especially the mserver program. So do the following:

First of all, I would appreciate if you do not post your entry ten times. Each time you edit it, you produce an email notification going to everybody, so
people might get annoyed to receive too many emails from you. Think what you want to write and then post once.
