AGTEK Access Server - Trackwork 2013

To support SmartTrack and Trackwork applications, the AGTEK Access server needs to change to accommodate new requirements. The first version of the server, written by external consultants, was a C++/Linux based server which had several issues. The second version of the server, written in Java/Linux, has been in production since 2009. A modified server implementation starting in 2014 is anticipated to support the track applications.

Story 0 - Leveling the base

We are anticipating that the trackwork will be significantly less than the original Java server implementation (2009) and should be less effort than the license extensions (2011). To prepare for the track extensions, the server needs to be in a relatively clean state. This will prevent any lingering server issues from introducing challenges to the track implementation.

The following items will set the base line for the track work:

  • Tag AgtekNet for pre-track work
  • Remove the remaining Box.net code.
  • Write report for keys created / month
  • Write report for checkouts / month
  • Write an autopruner for Apache tomcat
  • Enterprise work
    • Enterprise bit for said customers
    • Enterprise customers get reports
  • Fix desktop session monitor
    • Op/second graph doesn't update correctly.
    • Add tab showing operation times, min, max, median (graph over time?)
  • Fix C++ API to use time_t 64 bit
  • Wildcard user searches, add support to AccessSupport/KeyForge
  • Upgrade the server runtime to Java 7, latest build
  • Read SmartTrack stories, extract server requirements
  • Server bugs
    • 10 - Two checkouts in a row, more debugging?
    • 7 - Performance stats? Basic collecting?
    • 4 - Framework for purging licenselog, don't deploy

Story 1 - Base line

Provide the server base to support, at least, the capabilities required in SmartTrack.

  • Storage of normal tracks
  • Clean up
    • Remove TMM and TSM tables, drop table TMM; drop table TSM;
    • Remove RTK table, in each customer. drop table RTK; drop table RTKTRACK;
    • alter table TRACK set START, END, DISCOVERY, LARGESTGAP to bigint(20) ?
    • Add fix type to TRACK table, may be implied by API
    • Add ability to migrate tracks to S3
  • API extensions
    • Define constants for machine type
    • Management interface, CRUD directives
    • Remove Track fields; discovery_time, rejected_time, rejected_dop, last_version
    • Add Track field statistics | int(16)
    • New track statistics, extend TrackDB for this too.
      TrackStatistics
       {
          long    moving_seconds;      // delta seconds
          long    start_seconds;       // absolute time
          long    end_seconds;         // absolute time
          long    last_cycle_time;     // delta seconds
          long    average_cycle_time;  // delta seconds
          int     cycle_count;
          boolean is_metric;
          double  volume;        // CY for non-metric, M**3 for metric
          double  average_speed; // MPH for non-metric, KPH for metric
       } 

      Add a new table to the customer database

      TrackStatistics
       +--------------------+------------+------+-----+---------+----------------+
       | Field              | Type       | Null | Key | Default | Extra          |

       | cycle_count        | int(16)    | NO   |     |         |                |
       | is_metric          | tinyint(1) | NO   |     |         |                |
       | volume             | float      | NO   |     |         |                |
       | average_speed      | float      | NO   |     |         |                | 
       +--------------------+------------+------+-----+---------+----------------+
    • Position Object extensions
      • Add compass to recorded points in track file, Position objects represent if they have compass.
      • Add fixtype field
         Position
         {
            enum FixType {Auto, DGPS, Float, Fixed };
            FixType type;
            float   compass; // 0.0 .. 359.9999999
         }
      • Change PositionCodec and extend protobuf
      • Override upload to include project. The existing method operates as it does today. Tracks would be tagged with no project. Null will be acceptable for the StoredProject argument and makes this new method behave just like the old one.
        upload( StoredProject proj, String serial, List<Position> positions)
      • Make sure that the Position object is in the JavaDocs
      • Modify server track file format
        • Add version to header to allow server to deal with V1, V2, etc.
        • V2 files write values in float, include position type (AUTO, FIXED, etc)
    • Move Track/Position API to authenticated states in Server (require authentication)
    • Add ProjectAPI.deleteProject - will only succeed if project has zero tracks and zero files
    • Add login dialog to HaulSim
    • Modify HaulSim to be able to write GPX files.
    • Extend track file format to include compass, use floating point.
