Project Recovery Testing

Project Recovery test

Preparation

  • Before running these tests, set project recovery to run every 2 seconds. The instructions for this are on the Project Recovery concepts page.
  • Get the ISIS sample dataset from the Downloads page.
  • Get the file TOPAZ_3132_event.nxs
  • Put the data in a data directory, referred to as data_directory in the scripts below
  • Set up a directory to store output for comparison, referred to as testing_directory below

Time required 15 - 30 minutes

  1. Simple tests and Muon-esque workflow
  • Open MantidPlot - make sure no other instances of MantidPlot are running
  • Right-click in the Results Log and set Log level to Debug
  • The Results Log should be printing Nothing to save
  • Run the following command to create a simple workspace:
CreateWorkspace(DataX=range(12), DataY=range(12), DataE=range(12), NSpec=4, OutputWorkspace='NewWorkspace')
  • The Results Log should now be printing Project Recovery: Saving started and Project Recovery: Saving finished on alternate lines
  • Now run this script:
data_directory=<path-to-data>
testing_directory=<path-to-test>
Load(Filename=data_directory + '/INTER00013464.nxs', OutputWorkspace='INTER1')

  1. Multiple instances of Mantid
  • Open up MantidPlot, ensure that only one instance is running
  • Right-click in the Results Log and set Log level to Debug
  • The Results Log should be printing Nothing to save
  • Run the following script:
CreateWorkspace(DataX=range(12), DataY=range(12), DataE=range(12), NSpec=4, OutputWorkspace='NewWorkspace')
  • The Results Log should now be printing Project Recovery: Saving started and Project Recovery: Saving finished on alternate lines
  • Now start a second instance of Mantid - note on OSX this has to be done from the command line, as OSX will not allow two instances of an executable to be run using the open command
  • Set Log level to Debug
  • Watch the Results log for 30 seconds (or longer than your interval for project recovery saving, see the Preparation section)
  • No message about saving should be printed
  • Now, crash the first instance of Mantid with Segfault
  • Start a new instance of Mantid
  • This should also have no messages about saving
  • Close both instances of Mantid gracefully
  • Start a new instance of Mantid
  • You should be presented with the Project Recovery dialog
  • Choose Yes
  • This should repopulate your workspace window
  1. Recovering plots and windows
  • Open MantidPlot - make sure no other instances of MantidPlot are running
  • Run the second script from test 1
  • In the workspace window right-click the Sequential3 workspace and choose Plot spectrum
  • Choose Plot All
  • In the workspace window right-click the Sequential1 workspace and choose Plot advanced
  • Choose Tiled plot
  • Drag workspace Rename2 into the main window
../../images/reporter-test-4.png
  • Crash Mantid with Segfault
  • Reopen Mantid
  • You should be presented with the Project Recovery dialog
  • Choose Yes
  • Mantid should reload the workspaces and open windows, so you should see the plots and the data in the main screen.
  1. Test multiple instances of Mantid running
  • Open MantidPlot - make sure no other instances of MantidPlot are running
  • Run the script:
CreateWorkspace(DataX=range(12), DataY=range(12), DataE=range(12), NSpec=4, OutputWorkspace='NewWorkspace1')
  • Make sure that Log level is set to Debug in the results log
  • Open a second instance of Mantid
  • In the results log it should say Another MantidPlot process is running. Project recovery is disabled.
  • Run the script:
CreateWorkspace(DataX=range(12), DataY=range(12), DataE=range(12), NSpec=4, OutputWorkspace='NewWorkspace2')
  • Crash the first instance of Mantid with Segfault; choose Do not share information in the error dialog
  • Do not exit the second instance of Mantid
  • Restart Mantid
  • In the results log it should say Another MantidPlot process is running. Project recovery is disabled.
  • Close both instances of Mantid
  • Restart Mantid
  • You should be presented with a dialog offering to attempt a recovery - choose Yes
  • NewWorkspace1 should appear in the workspace dialog
  1. Opening script only
  • Open MantidPlot - make sure no other instances of MantidPlot are running
  • Run the second script from test 1
  • In the workspace window right-click the Sequential3 workspace and choose Plot spectrum
  • Choose Plot All
  • Crash Mantid with Segfault
  • Reopen Mantid
  • You should be presented with the Project Recovery dialog
  • Choose Only open in script editor
  • Mantid should open the script editor, with a script named ordered_recovery.py
  • Run this script, it should repopulate the workspaces dialog, but not open any figures
