There were some trivial and some non-trivial issues. Glad the compiled picked up on
this!

The linking of mhttpd misses a "-lm":

Before approving the code, two conditions have to be fulfilled:
1) The code has to work on PSI experiments

 16 Jun 2008, Stefan Ritt, Bug Fix, "Missing event" problem fixed in front-end framework
|
Since the very beginning midas had the problem that the last event of a run was
sometimes missing in the data. While for most experiments this is not an issue,
it starts to hurt on experiments using event building (front-end 1 and front-end

17 Jun 2008, Stefan Ritt, Info, Improvement of custom pages 
|
Some improvement of custom pages have been implemented. The idea behind is that
a custom page would contain a large background image containing indicators but
also controls. While indicators (values, bars) are already available, the field

I implemented improved alarm conditions in the alarm system. Now one can write

16 Jul 2008, Stefan Ritt, Info, Implementation of db_set_link_data() and db_set_link_data_index()
|
The current implementation of ODB links has the problem that once a link is
created, it cannot be changed any more through odbedit. This is because each
"set" command works on the destination of the link instead of the link. The same

31 Jul 2008, Stefan Ritt, Info, Improvement of custom pages
|
Even more improvements have been implemented into custom pages recently, containing a complete JavaScript library for ODB communication. This JavaScript
library relies on certain new commands built into mhttpd, and is therefore hardcoded into mhttpd. It can be seen by entering

17 Sep 2008, Stefan Ritt, Info, New flag for auto restart
|
A new ODB flag has been introduced. When the logger is configured for automatic
stop and restart (/Logger/Auto restart = y), the restart delay was hard-wired
to 20 sec., which might be too long or short for some experiments. Therefore a

18 Sep 2008, Stefan Ritt, Info, Potential problems in multi-threaded slow control front-end

We had recently some problems at our experiment which I would like to share
with the community. This affects however only experiments which have a slow
control front-end in multi-threaded mode.

19 Sep 2008, Stefan Ritt, Info, Lazylogger logging changed
|
I modified the logging behavior of lazylogger. Originally, it was writing
messages (run copied, removed, ...) both into midas.log and
lazy_log_update.log. Since we have many files, it kind of clutters up the

13 Oct 2008, Stefan Ritt, Info, mhttpd multi-experiment support removed
|
Previously, one mhttpd server could sever several experiments at the same time.
This caused however sometimes problems and was hard to maintain. Starting from
SVN revision 4348, I removed the multi-experiment support, which I believe is

28 Oct 2008, Stefan Ritt, Bug Report, Inconsistent handling of odb and evet buffer timeouts
|
> In midas.c there are several places where client last activity time stamps are checked against the

> ODB time stamps and data buffer time stamps appear to be handled in a similar manner.
