from xml and json file did not truncate arrays in odb to the size of arrays in

We have a MIDAS frontend that provides both the readout of raw events

Hi Tim,
Multiple Polling equipment are possible, but you may have to balance the polling

|
I'm using a python client to start and stop runs, and the following code *appears*
to set the MIDAS state to "Run"

29 Sep 2020, Ben Smith, Forum, using python client to start and stop run
|
The ODB variable "/Runinfo/State" is a symptom of starting/stopping a run, rather than the cause.
In C++, one uses `cm_transition()` to start/stop runs.

29 Dec 2010, Konstantin Olchanski, Bug Report, use of nested locks in MIDAS
|
A "nested" or "recursive" lock is a special type of lock that permits a lock holder to lock the same resources again and again, without deadlocking on itself.
They are
very useful, but tricky to implement because most system lock primitives (SYSV semaphores, POSIX mutexes, etc) do not permit nested locks, so all the logic |

25 Nov 2004, chris pearson, Forum, use of assert in mhttpd
|
We've had mhttpd aborting regularly since upgrading from midas-1.9.3. This
happens during elog queries, and is due to an elog file that was incorrectly
modified by hand. The modification to the file occurred 6 months ago.
