|
I am updating the TRIUMF IRIS experiment to the latest version of MIDAS. I see following error messages in midas.log:
19:06:16.806 2024/05/16 [mhttpd,ERROR] [odb.cxx:6967:db_get_data_index,ERROR] index (29) exceeds array length (20) for key

This is a common problem I also encountered in the past. You get a low-level ODB access error (could also be a read of a non-existing key) and you
have no idea where this comes from. Could be the alarm system, a mhttpd web page, even some user code in a front-end over which the midas library
has no control.

For everybody using EPICS: There is now a new system called MSetPoint (Midas Set Point) to control whole beamlines via EPICS.
It's under midas/msetpoint and the documentation is here:

18 Aug 2005, Konstantin Olchanski, Info, midas Makefile changes
|
Minor Makefile changes:
- add "-m32" gcc flag to force 32-bit compilation on 64-bit Linux.
- do not link ybos.o into lazylogger and mdump.

16 Oct 2015, Konstantin Olchanski, Info, midas JSON-RPC interface
|
To improve on the existing HTTP "GET" based AJAX interface to MIDAS, I have been looking at other possible RPCs.
The JSON-RPC standard looks to be the most interesting and my experimental implementation now reached the point where other midas users are welcome to |

28 Jul 2006, Konstantin Olchanski, Bug Fix, mhttpd: use more strlcpy(), fix a few bugs
|
While investigating the mhttpd password error with the MacOS Safari browser, I
found that it was caused by an strcpy() buffer overflow. With Stefan's blessing,
I now converted most uses of strcpy() and strcat() to strlcpy() and strlcat().

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. |

27 Feb 2008, Konstantin Olchanski, Bug Report, mhttpd: cannot attach history to elog
|
From "history" pages, the "create elog" button stopped working - it takes us to the elog entry form, but
then, the "submit" button does not create any elog entries, instead dumps us into an invalid history
display. This is using the internal elog.

This commit adds the elog message text to the outgoing email message. This
functionality has been requested a logn time ago, but I guess nobody got
around to implement it, until now. I also added assert() traps for the most

run comment)
