 01 Dec 2025, Konstantin Olchanski, Bug Fix, mvodb updated
|
I updated mvodb and test_mvodb. MIDAS ODB and JSON ODB now implement all API
functions. ReadKey, ReadDir and ReadKeyLastWritten were previously missing from
some implementations.

02 Dec 2025, Konstantin Olchanski, Info, cm_expand_env()
|
Just to remember, MIDAS has cm_expand_env() to expand environment variables, in
file paths, etc. It is used in several places in mhttpd, msequencer and mjsonrpc.

03 Dec 2025, Konstantin Olchanski, Bug Fix, no more breakage in history display when panning
|
In the DL experiment (unknown version of midas, likely mid-summer 2025), we see artefacts in the
history display where pieces of the data seem to be missing, there is gaps in the graphs. reloading the
page restores correct display confirming that in fact there is no gaps in the data. This made history

05 Dec 2025, Konstantin Olchanski, Bug Fix, update of JRPC and BRPC

With the merge of RPC_CXX code, MIDAS RPC can now return data of arbitrary large size and I am
proceeding to update the corresponding mjsonrpc interface.

I was testing odbxx with manalyzer, decided to print an odb value in every event,
and it worked fine in online mode, but bombed out when running from a data file
(JSON ODB dump). The following code has a memory leak. No idea if XML ODB dump

I updated the root helper constructor to give the user more control over ROOT output file names.
You can now change it to anything you want in the module run constructor, see manalyzer_example_esoteric.cxx

Hello Stefan,
is there a difference for the later data processing (after writing the ring buffer blocks)
