Fuming, fuming, fuming.
The combination of "make indent" and "svn update" completely trashed my work copy of midas. Half of

23 Feb 2007, Konstantin Olchanski, Info, RFC- support for writing to removable hard disk storage
|
At triumf, we are developing a system to use removable hard drives to store data collected by midas
daq stations. The basic idea is to replace storage on 300 GB DLT tapes with storage on removable
esata, usb2 or firewire 750 GB hard drives.

23 Feb 2007, Konstantin Olchanski, Info, RFC- history system improvements
|
While running the ALPHA experiment at CERN, we stressed and broke the MIDAS history system. We
generated about 0.5 GB of history data per day, and this killed the performance of the history plot
system in mhttpd - we had to wait for *minutes* to look at any plots of any variables.

I commited the mhttpd fixes and improvements to the history code accumulated while running the ALPHA
experiment at CERN:

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.

16 Mar 2007, Konstantin Olchanski, Info, RFC- history system improvements
|
> 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).

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.

10 May 2007, Konstantin Olchanski, Bug Fix, mhttpd: fix broken boolean arrays in "edit on start"
|
For some time now, boolean arrays did not work correctly in "/experiment/edit on start". This is now fixed
in rev 3680. K.O. |

For some time now, error reporting from cm_transition() was broken.
Typical symptom was when starting a run from mhttpd, when a transition error occurred, the run does not

10 May 2007, Konstantin Olchanski, Info, RHEL5/SL5 success!

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.

21 May 2007, Konstantin Olchanski, Info, mhttpd changes to use /History/Tags data
|
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.

07 Jun 2007, Konstantin Olchanski, Suggestion, RFC- ACLs for midas rpc, mserver, mhttpd access
|
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 commited a few minor changes to musbstd and mscb code to make them work on
MacOSX (tested on 10.3.9) and Linux (tested on Fedora 6).
