ParaView 4.3 testing Linux

[Owen Arnold]

• Install and uninstall
• Cube axes
• Re-binning
• Menus
• View switching.
• Default views and backgrounds via Preferences
• Overplotting Peaks Workspaces, zooming and selecting
• Drag and drop
• Launching the slice viewer from the multislice mode

Please report what flavour of linux you used in your test section for this ticket.

Ask Owen Arnold for data if you need it.

I'm testing on debian and Windows 7. For now I checked install/uninstall and basic usage with small datasets. Everything seems to work well. Menus, MD workspaces, peaks, different views, etc.

I really tried to fool it with another ParaView version that I had installed and it behaved solid like a rock.

The only extremely nit picky thing that I noticed is that if you try to save a screenshot when there's nothing being displayed it will show you an "it failed" error, but will not tell you why - or prevent you from saving nothing.

[Owen Arnold]

Thanks for this. Can you open a ticket about that screenshot issue and assign to Anton/cc Steve Hahn. We ought to try to fix that.

Tested nightly binaries 3.3.20150417.2020 on debian and windows 7. I also tested binaries built from the source distribution on debian.

I'd say with very high confidence this is all very robust, with the only exception of the shift-click slice viewer issue. It seems to work well with histo and event workspaces, peaks data, and file-backed workspaces. There doesn't seem to be any platform specific issue as far as I could see. I'm less confident about the multiple Rebin options. They all seem to behave but I don't know well enough their usage/behavior to tell with confidence whether the results are fine.

I tried to make it crash and/or misbehave with all the points in the list and anything else that I could perversely find in the GUI. Other functionality that seems ok: the time/frames play controls, help, using and abusing the tree of sources. All the tests were done with smallish files from the test data, although I also did a bit of torturing with a very large SQW file.

Well, in the end I managed to get a couple of crashes. One on windows and one on linux. But they are hardly reproducible and could well be related to my graphic card woes. Just noting them here in case they ring any bell:

• On windows, crash when switching from "Scatter plot mode" to "Three slice mode" while visualizing as surface an MD workspace coming from SEQ_MDEW that had been rebinned and sliced a bit randomly.
• On debian, crash while visualizing around ten different sources simultaneously, it seem to crash after a few rebins and perspective changes. This is the trace that I got:

Note on the status of this ticket:

• As far as I can tell all the issues found here, and related ones, were fixed last week. It overall looked solid and well behaved.

I'd add that I used to experience many random crashes with the older ParaView (no acceleration graphic card on Windows because of hardware issues, and virtual graphic card on Linux). And I think that 4.1 was still a bit unreliable. This issue seems to have gone away with the newer ParaView version used now in the VSI.
