I've managed to put the analyzer into state where it cannot connect to the

Hi folks:

30 Apr 2022, Konstantin Olchanski, Info, added web pages for "show odb clients" and "show open records"
|
for a long time, midas web pages have been missing the equivalent of odbedit
"scl" and "sor" to display current odb clients and current odb open records.

Concerning the "scl" page, we are currently having a discussion. At the moment, one can

the event dump is a hex dump for now.

there is a number of problems with implementing bm_receive_event() as a RPC:

Ubuntu 22 has almost everything necessary to cross-build arm64 MIDAS frontends:
