Day 1

06/06/2021

Initial workshop to discuss requirements and broad development strategy. See Meetings: Initial Workshop.

Day 2

07/09/2021

In which I:

• installed and set up intellij + python on my noctam PC
• created simplistic sim-start and sim-stop scripts to start and stop the CISSIM server
• got it up and running, which required a bit of jiggery-pokery:
  • needed to install windows-curses in my python environment: pip install windows-curses
  • Fixed a couple of relative paths hardcoded into a couple of python files. To wit:

   Don't rely on relative paths for files/folders
   
   Adds a 'getrootfolder' function to pdutils which gets the root folder of
   the 'project', by getting the parent of the directory in which the
   pdutils file is found.
   
   I can't immediately think of any problem with this, and it means you can
   run it safely from anywhere.
   
   This also dynamically alters the 'FOLDERS' config value (actually it
   checks of the config value starts with '../' and replaces '../' with the
   root folder provided by getrootfolder()) when it loads the config.

• Stepped it through a DCI913 call to get an idea of a) what it did, and b) how it did it. My notes are available, for now, but in a nutshell:

OK, this is actually quite flexible, and, although the code is terse and uncommented, it's not that hard to follow. Ultimately, it doesn't do that much (in the above, quite narrow, use case) - I could fairly easily strip out everything that isn't required by a DCI call and just have that as our starting block of code... I might do that, though I want to get PDD and NPS in there too, neither of which are handled in my initial examination above.

Day 3

08/09/2021

Plan

• Step through PDD processing in the CISSIM program
• Step through NPS processing too
• Document the aboves
• Start stripping out unused files / classes and reduce the program to its minimum codeset for ACS testing
• Start a design of the java version of it
  • I'll probably need to talk through some aspects of it (inputs / outputs) with the FDACS team, maybe tomorrow for that.

Execution

• Well, I stepped through the PDD processing
  • You can see the results at Notes/PDD Handling.
• I identified a few things which will need looking into - see Notes/CISSIM - the config processing is probably the main one since it's needed for PDD and it does some pretty meaty stuff at config loading time to determine the locations for the fields within PDD data blocks.
• NPS is at a bit of an impasse - I might shelve it to look at the config a bit more.
