The "Midas VME Standard API" has been revised. We tried to incorporate all

19 Sep 2005, Konstantin Olchanski, Info, Added driver for the Wiener CC-USB CAMAC interface

Commited to CVS is the preliminary driver for the Wiener CC-USB CAMAC interface.
The driver implements all the mcstd.h camac access functions, except for those
not supported by hardware (8-bit operations, interrupts) and a few esoteric

18 Aug 2005, Konstantin Olchanski, Bug Fix, fix race condition between clients on run start/stop, pause/resume

It turns out that the new priority sequencing of run state transitions had a
flaw: the frontends, the analyzer and the logger all registered at priority 500
and were invoked in essentially a random order. For example the frontend could

Minor Makefile changes:
- add "-m32" gcc flag to force 32-bit compilation on 64-bit Linux.
- do not link ybos.o into lazylogger and mdump.

I have been plagued by ODB corruption when I run the analyzer for the first time
after setting up the new experiment. Some time ago, I traced this to
mana.c::book_ttree() and now I found and fixed the bug, fix now commited to

05 May 2005, Konstantin Olchanski, Bug Fix, fix: minor bit rot in the example experiment

I fixed some minor bit rot in the example experiment: a few minor Makefile
problems, make the analyzer use the current histogram creation macros, etc. I
also added startup and shutdown scripts. These will be documented as we work

02 May 2005, Stefan Ritt, Info, strlcpy/strlcat moved into separate file
|
I had to move strlcpy & strlcat into a separate file "strlcpy.c". A header file
"strlcpy.h" was added as well. This way one can omit the old HAVE_STRLCPY which
made life hard. The windows and linux makefiles were adjusted accordingly, but

Current MIDAS versions nag me about setting the env.variable MIDASSYS to the
"midas installation directory", but I do not have one, so what should I set
MIDASSYS to? I checkout MIDAS from cvs into /home/olchansk/daq/midas, build it

25 Feb 2005, Konstantin Olchanski, Bug Fix, fixed: double free in FORMAT_MIDAS ybos.c causing lazylogger crashes

We stumbled upon and fixed a "double free" bug in src/ybos.c causing crashes in
lazylogger writing .mid files in the FORMAT_MIDAS format (why does it use
ybos.c? Pierre says- for generic file i/o). Why this code had ever worked before
