 20 Sep 2024, Stefan Ritt, Bug Report, Crash using ODB watch
|
The problem has been fixed in the current version. Here is my analysis:
- the midas::odb object *can* go out of scope in the function, since the odb::watch() function creates a deep copy of the object.

Dear experts,
I am a new user of MIDAS. I have just created some banks by a frontend.cxx code.
Now, I would like to do some analysis from the data.

"Can we convert the .mid file into .root file".
yes, you can, but the operation is under-defined. it's like asking "can I convert these stones into houses". the answer is "yes", but it involves

We're trying to install the SuperCDMS version of MIDAS on a Rocky 9.4 Virtual
Machine and are getting a persistent error when we run mserver. As far as I
know there are minimal changes between this and the MIDAS branch, but Ben Smith

We run Midas with no problems on Rocky 9.4, although not in a virtual machine. We're very close to the head of `develop`.
I'm fairly sure I've seen an error like this before. I didn't pay it much attention because it was transitory and I was doing something weird at the time |

I cannot read the core dump without the corresponding executable (and likely all it's shared libraries).

I read these error messages. There is no ODB corruption. ODB semaphore is locked and all midas programs will fail, they will timeout trying to get the lock,
report the timeout, then it looks like a bug was introduced where instead of hard exit or abort() they attempt a clean shutdown which crashes from a recursive
call in db_lock_database(). Amy's

11 Oct 2024, Denis Calvet, Bug Report, Frontend name must differ from others by more than the last three characters

Hi,
I have developed two Midas front-end programs for different hardware. The frontend_name of the first one is "FSCD_SC" (slow control) and that of the second
one is "FSCD_PS" (power supply).

Thank you for the stack trace, I fixed the buglet that cause midas programs to crash twice,
once on failure to lock ODB, then call exit() -> atexit() handlers -> cm_check_connect() -> crash on ODB lock
failure is the cm_msg() codes.
