After autorefit the refitted vehicle doesn't reserve cargo in case of improved loading. This may lead to a later vehicle "stealing" cargo that should be loaded by the just refitted one.

Please send me e-mail via private message, then I'll send you crash.* files.

Splitting a link graph component could be done when removing a link.

1. Check with BFS if both ends, A and B, of the removed link are still in the same component. If yes, nothing has to be done. BFS can be aborted if the other node is found.
2. Create two new components.
3. Run a full BFS starting at A and copy each found node into the first new component.
4. Run a full BFS starting at B and copy each found node into the second new component.
5. Delete the old component.

This should be fairly cheap if the nodes are still connected. It might be cheaper to "compress" the remaining component after step 3 instead of recreating and deleting it.

Joining two components is simply a matter of concatenating them, adding all edges in the right places and adjusting each node ID in the second component by the size of the first component.

The overlay should only show links the selected companies are serving. However, as that is not detectable by the linkgraph itself, the filtering is done by station owner, assuming that a station can only be served by its owner. However, in the case of neutral stations, the station can be served by anyone and furthermore, the same link can "contain" vehicles of different companies. There is no obvious fix for that. Options include:

1. When encountering a link between two neutral stations when building the overlay check all vehicles serving that link and then decide which companies it belongs to. This is a hack because for all other links we don't need to check the individual vehicles.
2. Somehow store ownership of a link or a link graph in the link graph itself. This is complicated as neutral stations can be used as inter-company transfer points for cargo. This is a weird concept, already in trunk, as it allows a company to get the profit for the transporting another company has done. The problem is worsened by the fact that cargodist automatically transfers cargo.

The event of having links between two neutral stations might be so rare and the effect of the bug so insignificant that it may not be worth the extra code to fix it.

WIth Cargodist cargo at the station may be heading in different directions than the vehicle being loaded. So deciding which cargo to refit to based on overall amount of cargo at the station is misleading; there may be a lot of cargo waiting but the vehicle is not necessarily able to load it.

The heuristic should be changed to check for cargo going in the same direction as the vehicle.

When starting the latest version of cargodist (commit aeed7eee244168c19577575144eb9cef5d942367), openttd segfaults:

Note that it seems to work just fine when it is compiled with CFLAGS=-O0 or -O1.

Instead of keeping a separate data structure for link stats they can equally well be directly rwitten to the link graph components. This involves creating and joining link graph components on the fly and updating them where link stats are updated now.

With the current way of measuring link capacity links have to be visited frequently in order for cargo distribution to consider them. There is a timeout based on the distance the link covers. When that timeout is hit the link is removed. Cargo can only be automatically distributed over links known at the moment when the link graph is created.

Players don't understand that and complain about their cargo not being automatically distributed when links are visited only rarely.

Cargo is always reserved so that each vehicle is filled up in the order they're processed. So the first vehicles in a consist are reserved up to their capacity while the last ones may be left empty. If cargo is loaded from reservations then there is no "gradual loading". This might be fixed by restricting the amount of cargo reserved in ReserveConsist in economy.cpp.

Game crashed while I was just creating a new Train (but has possibly nothing to do with that)

*** End of additional info ***

Instead of constantly visiting all stats to apply moving averages capacities can be constantly incremented without any correction until the link graph jobs are run. A member "start_date" of Edge would tell how long the stats collection is already running.

There should be an additional link graph job which would "compress" all link stats by dividing capacity by a certain factor and setting the start_date to something more recent. It could also handle splitting due to link timeouts.

When task 4 is done we can construct a meaningful linkgraph on the fly. This means we can add passby (with either loading or unloading allowed), import and export nodes while knowing all orders. Thus we don't need any strange flag collections and extra station IDs any more to signal order modifications to the link graph. We also don't need a normalizing link graph job then.
