 15 Nov 2013, Konstantin Olchanski, Bug Report, stuck data buffers
|
We have seen several times a problem with stuck data buffers. The symptoms are very confusing -
frontends cannot start, instead hang forever in a state very hard to kill. Also "mdump -s -d -z
BUF03" for the affected data buffers is stuck.

20 Nov 2013, Konstantin Olchanski, Bug Report, Too many bm_flush_cache() in mfe.c
|
I was looking at something in the mserver and noticed that for remote frontends, for every periodic event,
there are about 3 RPC calls to bm_flush_cache().

15 Jan 2014, Konstantin Olchanski, Bug Report, MIDAS password protection is broken

If you follow the MIDAS documentation for setting up password protection, you will get strange messages:
ladd00:midas$ ./linux/bin/odbedit

15 Jan 2014, Konstantin Olchanski, Bug Report, MIDAS Web password broken
|
The MIDAS Web password function is broken - with the web password enabled, I am not prompted for a
password when editing ODB. The password still partially works - I am prompted for the web password
when starting a run. K.O.

The periodic messages about broken semaphore actually come from al_check(). I put some whining there, too.

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 |

Hi,
I don't know if this actually fits the Bug Report category. I've been trying to install Midas on my Mac OS

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.

For my reference:
good version: https://bitbucket.org/tmidas/midas/src/6899b96a4f8177d4af92035cd84aadf5a7cbc875/src/mfe.c?at=develop

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.

|
Doing this through the ODB seems ok to me. If the ODB cannot be accessed, you can fall back to no protection.
At PSI we fortunately do not have these network scans because PSI uses a institute-wide firewall. So you can connect from outside PSI to inside PSI only |

You are absolutely correct, the code is certainly wrong. It looks to me like the
