resize_net_send_buffer() (at least this was the only place I could find

12 Dec 2011, Michael Murray, Bug Report, bk_delete uses memcpy instead of memmove

In midas.c, the bk_delete function removes a bank by decrementing the total
event size and then copying the remaining banks into the location of the first
using memcpy from string.h.

Stefan's fix is incomplete - the "gzFile" cast is needed for all calls to zlib, not just those that some version
of GCC happens to complain about. Fixed.
svn rev 5286.

29 Feb 2012, Konstantin Olchanski, Bug Report, Problem with semaphores
|
Hi there! In the T2K/ND280 experiment in Japan, we keep having problems with MIDAS locking (probably
of ODB). The symptoms are: some program reports a timeout waiting for the ODB lock, then all programs
eventually die with this same error. Complete system meltdown. This does not look like the deadlock

24 Jun 2011, Exaos Lee, Suggestion, Build MIDAS debian packages using autoconf/automake.
|
Here is my story. I deployed several Debian Linux boxes as the DAQ systems in our lab. But I feel it's boring to build and install midas and its related
softwares (such as root) on each box. So I need a local debian software repository and put midas and its related packages in it. First of all, I need a
midas debian package. After a week's study and searching, I finally finished the job. Hope you feel it useful.
