history display dropouts
there is a bug in the history display zoom-out updates - I see data drop-outs where data for part of the graph is missing. pressing browser “reload” button reloads the data correctly without the drop-out. I need to find a way to reproduce this before asking Stefan to try to fix it. K.O.

reporter there is no aborted rpc calls or rpc errors (unless history-load rpc errors are not reported/displayed). but the missing chunks do seem to correspond to missing results from an rpc call. still have no recipe to reproduce this, so we cannot debug it yet. K.O.

All rpc errors from
hs_read_arraybuffer
are reported. -
reporter just got a drop-out zooming into https://daq16.triumf.ca/?cmd=History&group=PWB&panel=v_p2&A=1593462776&B=1596227576
I was pressing the zoom-out button “too quickly”. Page reload fixed the drop-out.

reporter Also see dropouts when panning to see older data. K.O.

I changed a thing there. Can you try with the current version if your dropouts are gone?

reporter - changed status to resolved
I do not see any dropout anymore, I guess it is fixed. K.O.

The only way I can think of is that one of the “chunks” we are loading would be missing due to an aborted RPC call. Maybe you can look in that direction.
