 07 Jun 2007, Konstantin Olchanski, Suggestion, RFC- ACLs for midas rpc, mserver, mhttpd access
|
Running MIDAS at CERN is proving more challenging than I expected. The network environement is not
as benign as I am used to (i.e. at TRIUMF) and our machines are being constantly probed by something/
somebody.

20 Aug 2007, Konstantin Olchanski, Bug Report, how to handle end of run?
|
I am having problems with handling the end-of-run situation in my midas
frontend. I have a device that continuously sends data (over USB) and I read
this data in my "read_event" function.

It looks like ODB function extract_key() will overwrite the array pointed to by "key_name" if given an odb
path with very long names (as seems to happen when redirection explodes in the Safari web browser, via
db_get_value(TRUE) via mhttpd "start program" button). All callers of this function seem to provide 256
