22 Oct 2004, Konstantin Olchanski, Bug Fix, mhttpd message colouring

I commited a fix to mhttpd logic that decides which messages should be shown in
"red" colour- before, any message with square brackets and colons would be
highlighted in red. Now only messages matching the pattern [...:...] are

I am commiting MIDAS modification accumulated during the last few months of running TWIST:
1) system.c::ss_shm_open() fail if trying to map a file that is smaller than we expect.
2) midas.c::bm_lock_buffer(), el_submit(), el_delete_message(): do not wait for mutexes forever, use a 5

20 Jan 2005, Konstantin Olchanski, Suggestion, HOWTO create ROOT objects in the MIDAS analyzer
|
With recent changes to mana.c, creation of user ROOT objects in the MIDAS
analyser has changed. Here is the new example code for creating ROOT objects

20 Jan 2005, Konstantin Olchanski, Bug Report, Persistency problem with h1_book() & co
|
The current h1_book() macros (and the previous example analyzer code) have an
odd persistency problem: for example, the user wants to change some histogram
limits, edits the h1_book() calls, rebuilds and restarts the analyzer, starts a

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

21 Apr 2005, Konstantin Olchanski, Suggestion, Correct MIDASSYS setting?
|
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

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

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

18 Aug 2005, Konstantin Olchanski, Info, midas Makefile changes

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.

18 Aug 2005, Konstantin Olchanski, Info, CAMAC register_cnaf_callback()
|
Some time ago, the "remote CAMAC" functionality in mfe.c was made conditional on
HAVE_CAMAC. This flag is not set by default so remote camac calls silently do
not work, unless midas is compiled in a special way. I am too lazy to compile
