A PTC Back Office Server with web interface, track/locomotive simulators, and EMP messaging subsystem.

ptc-sim's Issues

Status map track lines don't update in web if changed server side.

Note that this is currently a non-issue, because they're never changed server side. However plans exist to change them based on milepost status in the future - this needs fixed before then.
Also note that changing track lines client-side may be expensive, because there are potentially a large number of them.

Persistent loco infoboxes don't stay with the loco as it moves along the map

Heroku deployment unstable

Port binding fails with ADDRESS ALREADY IN USE and after a minute or two of runtime, memory usage exceeds 500mb limit (presumably as a result of multiple threads failing/restarting due to port bind issue).

Persistent map infoboxes are not functional

On asynch refresh, the status map's currently open infobox goes away.
Correct behavior:

If (!curr selected loco) {
    // persist currently open infobox
} else {
    // persist currently open infobox if non-loco OR if curr_selected_loco
}

Connection timeout watcher prevents graceful exit.

lib_msging.Connection._timeoutwatcher does not allow graceful exit when the sim_track, sim_bos, and sim_broker modules are run individually. It likely needs a stop function. The line to start the thread in Connection.init() is commented out in the meantime.

Track sim exists as a single instance, so multiple web users adjusting settings will be fighting each other's commands.

Fix: Each web session needs its own track instance, so the devices are simulated according to that sessions settings.

Map markers don't have onlick listeners until after first asynch refresh

Need to fix this in home.js

Right side of locos table bounces on shuffle effect

Need to set the status col to a fixed width or set overflow-x:hidden.

Convert to py3

Convert the existing PTC-Sim code base to Python 3. Most of it is done, but the struct.pack and decode functions are causing problems.
