Hi,
I would like to raise the question where to put the midas drivers.

[quote="Stefan Ritt"]We have both the example experiment and the MSCB Makefile which both expect to find the midas drivers under [b]$MIDASSYS/drivers/camac[/b]
or [b]$MIDASSYS/drivers/usb[/b]. The documentation does not explicitely mention to define MIDASSYS as [b]/usr/local[/b], but some people do it. That however
requires to put all drivers then under [b]/usr/local/drivers[/b], which is not the case in the current Makefile for midas. Do you think that we should |

28 Dec 2005, Konstantin Olchanski, Suggestion, Handling multiple identical USB devices
|
When I wrote the musbstd.h "open" method, I kind of punted on the problem of
handling multiple identical USB devices. Instead of a real solution, I added an
"instance" parameter, which allows one to "open" the "first", "second", etc USB

Dear midas users,
The current event size in midas is limited to 512k (MAX_EVENT_SIZE in midas.h). This is mainly due to old (pre 2.2) linux kernels which had only a very |

|
Since nobody complained so far, I increased MAX_EVENT_SIZE to 2MB. If anybody has problems with this setting, please report. Note that after updating to
SVN revision 3327 it will be necessary to recompile [U]all[/U] midas programs and to delete any old [B]SYSTEM.SHM[/B] or [B].SYSTEM.SHM[/B]. I added some
code which should check for inconsistent SYSTEM.SHM sizes, but I'm not sure if it works everywhere. |

Yes, 512 kBytes is rather small. For the T2K prototype TPC DAQ, I built and ran

[quote="K.O."]Now, we have per-buffer tunable size (see message

05 Jan 2007, Eric-Olivier LE BIGOT, Suggestion, Access to out_info from mana.c

Would it be relevant to transform out_info into a *non-static* variable of a type
defined by a *named* struct?
Currently, programs that try to access out_info cannot do it anymore; and they

I changed out_info into a global structure definition ANA_OUTPUT_INFO and put it into
midas.h, so it can be accessed easily from the user analyzer source code.

Running MIDAS at CERN is proving more challenging than I expected. The network environement is not
as benign as I am used to (i.e. at TRIUMF) and our machines are being constantly probed by something/
somebody.

I am in favor of tcp_wrappers.
tcp_wrappers is well understood.

08 Jun 2007, Stefan Ritt, Suggestion, RFC- ACLs for midas rpc, mserver, mhttpd access
|
First I have a general question: mserver is started through xinetd, and xinetd has
the options "only_from" and "no_access". This is equivalent to the tcp_wrapper
functionality. Why not using this? It's possible without changing anything in midas.

I rearanged the files in "examples/experiment" as the attached "mtest_exp.zip". I re-write the start/stop script as the attached "daq.sh". The script "daq.sh"
can be re-used for many experiments. The user only needs to provide an script "daq_env.sh" as the following containing the settings for the experiment
environment.
