 04 Sep 2006, Konstantin Olchanski, Bug Fix, Fix MIDAS on MacOS 10.4.7
|
I commited minor fixes for building MIDAS on MacOS 10.4.7:
1) there is no linux/unistd.h
2) gcc 4.0.0 does not like "struct { ... } var;" although "struct Foo { ... } var;" is fine

For the record, the MIDAS (& co) forums have been physically moved from
dasdevpc.triumf.ca to our new server machine ladd00.triumf.ca. This change
should be transparent to all users, but if anything stops working, please let me

Aparently the mhttpd elog will corrupt the elog files if two (or more?) elog entries are being edited at the

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.

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).

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.
