4eebeff58c (svn r2324) Introduce _cmd_text for passing strings with a command instead of abusing _decode_parameters as text buffer. This should prevent several possible buffer overruns and is a bit cleaner to use. As bonus it reduces the size of most command packets by 79 bytes. 2005-05-15 18:50:55 +00:00

7470322a3d (svn r2306) - CodeChange: Check the last commands; refits. This needed an extensive rewrite and global/local-cargo ID juggling and bitmasking. However with this done it looks better as well and is compatible with newgrf handling. Big thanks to HackyKid for doing most of the work. This also closes patch "[ 1199277 ] Command checks" 2005-05-14 12:36:16 +00:00

ddd4958164 (svn r2300) - CodeChange: check the last number of commands, now only the refit ones remain, and some server-only commands.
- CodeChange: remove cmd-misuses CmdStartScenario() and CmdDestroyCompanyHQ()
- Fix (invisible): when parameter checking CmdRestoreOrderIndex() the vehicle did not have its orders yet, so it would fail. So move doing this until AFTER the orders have been added back in RestoreVehicleOrders()

562a32c3ee (svn r2297) - CodeChange: server-check the next batch of commands.
- CodeChange: since only the server will be able to modify difficulty settings, leave the checking of correct values besides, and trust users will join legit servers.
- CodeChange: for renaming signs, only check if GetDParam(); eg _decode_parameters is empty ('\0') or not, instead of the extra check of players, etc. That basically does the same thing. Also dirty sign two times when renaming, once before, once after the action. Because if the name becomes shorter and you update only after, garbage remains on the screen.
- CodeChange: made GetMaskOfTownActions() available to the town-cmd to double-check if the action was available to the player. For this purpose the hardcoded _local_player has been removed from the function and is now passed as a parameter.

b43331c931 (svn r2290) - CodeChange: protect the next batch of commands. This brings us to a total of 61, which is 53% :)
- CodeChange: To correctly accept engine-prototypes, the best-player checking has been moved to its own function, I hope it functions the same as before.
- CodeChange: Added symbolic types of PlayerID, OrderID and EngineID. For engines also added GetEngine() and IsEngineIndex(), similar to the other such functions.
- CodeChange: To correctly build industries, some tables have been moved to build_industry.h. The only way to find out currently if an industry is valid in a climate is by looping all industries and checking if it matches. Also to comply with the patch setting build_rawmaterial_industries, it is assumed that these industries do not accept any cargo of any type. This can and probably should changed in the future to some flag in their struct. Also use _opt_ptr instead of _opt.
- CodeChange: implemented the HQ checking code inspired by MarkR2 in "[ 1190944 ] Many commands not checked for security".  Unfortunately it is impossible to prevent only deleting a HQ by a modified client atm.
- CodeChange: For insert order and modify order their parameters are implicitely truncated to 8 bits, instead of the 16 bits said in the comments.

f04ba0b679 (svn r2262) - Fix: Assertion when vehicle in a depot wants to do pathfinding.
GetVehicleTrackdir now tries to get a valid trackdir as much as possibly, by assuming that a vehicle is facing outwards in a depot or road station, for example.
- Codechange: [Multistop] Multistop now also tries to find a slot for road vehicles that are in stations, since the pathfinder now properly handles that.

f8302a137a (svn r2256) - Fix: Trains cannot find a depot when they are in a tunnel. (glx)
- Add: GetVehicleTrackdir() helper function.
- Codechange: Moved SortStruct from vehicle_gui.h to ttd.h, so the dependency from vehicle.h on vehicle_gui.h could be removed.
- Codechange: Typedeffed the VehicleTypes struct so it can be used as the type for Vehicle.type instead of "byte".
- Codechange: Removed prototype for VehicleSorter(), which had no implementation anymore and was never called.

7669c4d0c2 (svn r2239) -Fix [autoreplace]: [ 1185653 ] autoreplacing a dualheaded engine into a singleheaded engine is no longer a potiontial crash
It do have one side effect through. Now no engines are added/removed from the train anymore, so it produces "half dualheaded engines"
	This will be fixed when autoreplace will get a major overhaul at a later date

that. Hopefully this fixes those problems. With a big tnx to BJH for his

e5abf58461 (svn r2024) -Fix: [autoreplace] reverted all changes involving v->set_for_replacement as they caused desyncs.
The bad sideeffect of this is that now no vehicle will automatically go to a depot anymore just 
because it is set to be autoreplaced. We will have to find a better way to solve this problem.

Revisions reverted: 1640, 1707, 1709, 1710, 1712(but not the cheat prevention in this one)

Checks like this is needed to protect network servers from people, who hack their clients to either cheat or crash the server

NOTE: if I made a mistake here it can make a function unreachable when it should be used. Here is one place to look if something weird happens
