|
I confirm I see same on the agmini system. Two problems: (a) error message is wrong, it's a
short read, not a read error (clue: read() syscall does not return "no such file"). (b)
mlogger is supposed to write history in record-size blocks, read in the same record size

A bit of update to the mlogger. In preparation for more cleanup when Stefan is

I started to get web browser popups about "midas wants to show notifications,
block/allow/x". is this a glitch or a new unannounced/undocumented feature?

Confirmed. The error message is wrong. It is printed after a short read(), but short read() does not
set errno, and errno reported by the error message is from some previous syscall. Corrected error
message is already committed. K.O.

|
I believe the original "hide run start / stop" was added specifically for ND280 GSC MIDAS. I do not know
why it was removed. "hide pause / resume" is still there. I will restore them. Hiding logger channel
section should probably be automatic of there is no /logger/channels, I can check if it works and what

both the xml and the json decoders have a bug (fix pending). loading saved odb
from xml and json file did not truncate arrays in odb to the size of arrays in
the file. for example, if /example/double_array has size 20 in odb, but size 5

We are very happy with the "FILE" implementation of MIDAS history and it is time
to make it the default for new experiments. This history driver works best if
"per variable" history is alos enabled. (SQL history already only works in "per-

Stefan is right. I forgot this. As solution to our troubles, mlogger is built without root support. use rmlogger instead.
