One of our experiments is suffering from periodic ODB corruption and I
suspected that there might be a problem with ODB locking. In the last few
days, I finally had time to read the ODB locking code, to write a little

31 Aug 2004, Konstantin Olchanski, , mlogger crash if using mserver.
|
Our users keep making a simple mistake- they set MIDAS_SERVER_HOST in their
environement. Most midas programs do not mind this- they go through the
mserver, inefficient but benign- except for the mlogger, which dumps core

|
At TRIUMF, we use several different versions of code to interface MIDAS and
EPICS (http://www.aps.anl.gov/epics). Now that we more or less understand
our needs, I propose this design for a simplified "EPICS" MIDAS frontend. I

After a felicitous confuence of stellar bodies (Stefan, myself, some mscb hardware
and a mac laptop all in the same room for a few days), I wrote some MacOSX
code to support the MSCB-USB dongle using the native IoKit USB API. During testing,

Right. We cannot fix the past, but we should fix the future. BTW, "do not mix versions" is hard to enforce and mismatches did, do and

13 Oct 2004, Konstantin Olchanski, Bug Report, db_paste: found string exceeding MAX_STRING_LENGTH

I am updating TWIST to the latest MIDAS and when I load a saved .odb file, I get
these messages. Their text ought to say where and what strings it does not like.

odbedit command "rename Display xxx/yyy" creates a key named "xxx/yyy" (yes,
with a slash in the name) and this key cannot be deleted or renamed...

We have al_trigger_alarm(), but no matching al_clear_alarm(), and I need it to
clear my alarm once the alarm condition no longer exists. Any objections if I
add this function? K.O. |

The upgrade of TWIST to the latest midas has bombed- we see mevb and mlogger
crashes during shared memory data buffer accesses. I am looking into it and I
will add information as I figure things out. K.O. |
