In close cooperation with Stefan, I refactored and rewrote the MIDAS event
buffering code (bm_send_event, bm_flush_cache, bm_receive_event and bm_push_event).

Some time ago, I accidentally introduced a bug in mfe.c- if there is data
congestion in the system, mfe.c can exit with the error "bm_flush_cache(ASYNC)
error 209" because it did not expect the valid return value BM_ASYNC_RETURN

01 Aug 2006, Konstantin Olchanski, Bug Fix, User-tunable buffer sizes

By default, MIDAS creates shared memory event data buffers of default size
EVENT_BUFFER_SIZE defined in midas.h and until now making of large data buffers
for high data rate or large event size experiments was complicated.

I now converted most uses of strcpy() and strcat() to strlcpy() and strlcat().

The ALPHA experiment at CERN has recently adopted MIDAS, and the history data in numerical form is needed by the collaboration. Furthermore the DAQ is running
under linux and most collaborators are windows or mac users, so it should be available in a platform independent way.

[quote="Art Olin"]Basically we need the output from the mhist code. The most convenient, and possibly easiest implementation would be to select required
data (ID, variable, time range) in the midas history display, click a button requesting file output and input a file name. One might also want to specify
the interval time required.[/quote]

Hi Art,
you can make the process somewhat less painful by using the Plink (from PuTTY) to run mhist as a remote command, piping the output to a local file:

13 Jun 2006, Stefan Ritt, Info, Scheduler changed for slow control equipment
|
The schedule in mfe.c is used both for "normal" front-ends and for "slow-control" front-ends. Unfortunately it was only optimized for the first class. This
lead to the fact that the slow control equipment was read out at different speed depending if the run is started or not. Furthermore, the maximum readout
speed was somehow limited. This has been changed in the current version of mfe.c (SVN revision 3146). There are now two ways to control the readout speed |
