I did not know this command, so I read about it. This IS WONDERFUL! I had once (actually with MSCB) the case that a bug was introduced i the last 100

[quote="Thorsten Lux"]In addition now I cannot start anymore the mlogger from the web interface but only manually. However, I can stop it from the web interface.[/quote]
At least that one can be fixed easily. Each program has a certain command with which one can start it. This has to be put into the ODB under /Programs/<program>. |

Ok, so here is what probably happened. Some user program wrote a long string into the ODB and somehow corrupted it. This corruption persists as long as |

 23 Sep 2013, Stefan Ritt, Info, Custom page header implemented 
|
Due to popular request, I implemented a custom header for mhttpd. This allows to inject some HTML code
to be shown on top of the menu bar on all mhttpd pages. One possible application is to bring back the old
status line with the name of the current experiment, the actual time and the refresh interval.

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 |
