 24 Sep 2013, Stefan Ritt, Info, mktime() and daylight savings time
|
I vaguely remember that I had a similar problem with ELOG. The solution was to call tzset() at the beginning of the program. The man page says that
this function is called automatically by programs using time zones, but apparently it is not. Can you try that? There is also the TZ environment
variable and /etc/localtime. I never understood the details, but playing with these things can influence mktime() and localtime().

24 Sep 2013, Stefan Ritt, Bug Report, mhttpd truncates string variables to 32 characters

Actually this was no bug, but a missing feature. Strings were never meant to be extended via the web interface.
Now I added that feature to the current version. Please check it.

Yes. Of course runs will not be started/stopped when mhttpd is not running, but when you restart it gracefully continues where it stopped, since all variables |

Seems to me a problem with the ODBC library, so maybe Konstantin can comment.

Since several projects at PSI need MSCB but not MIDAS, I decided to separate the two repositories. So if you
need MIDAS with MSCB support inside mhttpd, you have to clone MIDAS, MXML and MSCB from bitbucket
(or the local clone at TRIUMF) as described in

This is interesting. When I used it last time (some years ago...) it worked fine. I did not touch this, and now it's broken. Must be related to some modifications |

As reported in the bug tracker, the proposed header does not work if no specific (= different from the default 60 sec.) update period is specified,
since then no cookie is present. Here is the updated code which works for all cases:
