Experimental Physics and Industrial Control System
Hi:
I remember Kunal reporting a similar problem, also related to synchronization.
You added synch. in the ArchiveFetchJob, but that is the generic part which interfaces to all types of archive readers, and those readers are expected to support multithreading.
Kunal added a lock to ApplianceValueIterator, see https://github.com/ControlSystemStudio/cs-studio/commit/d902628f7272ca9b3d392a4d8636533799d5738d
Check that your sources include this lock.
If so, maybe you need to add/modify the locking in the ApplianceOptimizedValueIterator similar to what Kunal did in the ApplianceValueIterator.
Thanks,
Kay

Subject: Trend graph partly not shown in Data Browser with Archiver Appliance
Dear All,
I have a problem with Data Browser with Archiver Appliance that trend
graph is partly not shown.
It happens if I plot 2 or more trends with large number (e.g. 20000 or
more) of samples at the same time. See attached screenshot for what I
want and what I got. The missing part will appear if I toggle from RAW
to OPTIMIZED and again back to RAW (or vice versa). The missing part
may change when I restart CS-Studio.
I'm using:
- CS-Studio 4.4.1 (as of 2017 Apr. 24)
- Archiver Appliance v0.0.1_SNAPSHOT_20-Sept-2016
When I made a quick and dirty workaround such that synchronize inside
for-loop in ArchiveFetchJob::run(). All the data will be shown as I
want, but Data Brower fails to cancellation of data retrieval.
Any help would be appreciated and thanks in advance.
Best regards,
Shuei YAMADA
