 21 Feb 2014, Konstantin Olchanski, Info, Javascript ODBMLs(), modified ODBMCopy() JSON encoding
|
I made a few minor modifications to the ODB JSON encoder and implemented a javascript "ls" function to
report full ODB directory information as available from odbedit "ls -l" and the mhttpd odb editor page.

mhttpd.css is served from $MIDASSYS/resources/mhttpd.css. The actual path is reported on the mhttpd

11 Jul 2014, Konstantin Olchanski, Info, MIDAS high speed test
|
We have tested operation of MIDAS using a 10GigE network connection. Using a dummy frontend
generating fake data, we can record MIDAS data to disk at at least 700 Mbytes/sec as reported by
the MIDAS status page.

14 Oct 2014, Konstantin Olchanski, Bug Report, Problem in mfe multithread equipments
|
In the ALPHA experiment at CERN I found a problem in mfe.c handling of multithreaded equipments. This problem was in
some forms introduced around May 2013 and around Aug 2013 (commit
https://bitbucket.org/tmidas/midas/src/45984c35b4f7/src/mfe.c) (I hope I got it right).

14 Oct 2014, Konstantin Olchanski, Bug Report, Hostile network scans against MIDAS RPC ports
|
At CERN I see a large number of hostile network scans that seem to be injecting HTTP requests into the
MIDAS RPC ports. So far, all these requests seem to be successfully rejected without crashing anything, but
they do clog up midas.log.

14 Oct 2014, Konstantin Olchanski, Bug Report, Problem with EQ_USER
|
If you use EQ_USER in mfe.c and have multiple threads writing into the ring buffer, you will have a big
problem - the thread locking in the ring buffer code only works for a single writer thread and a single
reader thread.

27 Jan 2015, Konstantin Olchanski, Bug Report, getaddrinfo()

To support IPV6, we need to migrate MIDAS from gethostbyname() to getaddrinfo(). (Thanks to
