 15 Mar 2007, Konstantin Olchanski, Info, mhdump: a standalone MIDAS history dump utility
|
While working on improvements to the MIDAS history system, I understood the data
format of the MIDAS .hst files and wrote a standalone program to extract data
from them, called mhdump.

> Let's improve the midas history system...
After implementing 2 prototypes, one aspect of the new design is starting to firm up enough to write it down (I do so in a mock FAQ format).

03 Apr 2007, Stefan Ritt, Info, Switch to Visual C++ 2005 under Windows
|
I had to switch to Visual C++ 2005 under Windows. This required the upgrade of
all project files under \midas\nt\ and fixing a few warnings, since the new
compiler is more picky.

09 Apr 2007, Konstantin Olchanski, Info, move history, elog and alarm functions into separate files
|
As approved by Stefan, I moved the history (hs_xxx), alarm (al_xxx) and elog (el_xxx) functions out of
midas.c into separate files. Commited as revision 3665. This change should be transparent to all users.

FWIW, I am running latest 32-bit MIDAS on an AM2 dual core AMD machine under 64-bit SL5. Everything
seems to work correctly. K.O.

I am slowly commiting the changes to the history code. This installement adds
code to mhttpd to use the /History/Tags data (to be) generated by the mlogger.

26 Jul 2007, Stefan Ritt, Info, Change of pointer type in mvmestd.h
|
I had to change the pointer type of mvme_read and mvme_write to (void *) instead
to (mvme_locaddr_t *) to avoid warnings under 64-bit linux. Please adjust your
VME drivers if necessary.

I now commited the changes to mlogger (mlogger.c, msystem.h) implementing data
compression using zlib (svn revision 3845)

06 Sep 2007, Stefan Ritt, Info, Introduction of MIDAS_MAX_EVENT_SIZE
|
We had the problem that different experiments used different MAX_EVENT_SIZE
values (the MEG experiment actually 10 MB!). If each experiment changes the
value in midas.h and accidentally commits it, other experiments are affected.

The ROODY online histogram viewer and the ROOTANA midas analyzer toolkit have been updated to work
with ROOT version 5.16 and tested on Linux (SL4.4) and MacOS (10.4.10/PPC).

The midas history system always had the problem that the database can get
corrupted if the disk gets full where the history records (*.hst & *.idx) are
stored. This can happen if a history event can only be written partially on the

A major change was made to mhttpd, changing all internal URLs to relative paths.
This allows proxy access to mhttpd via an apache server for example, which might
be needed to securely access an experiment from outside the lab through a
