Warning to overflow of convoi IDs March 22, 2009, 11:22:39 am I realised that there is no warning to the overflow of convoi IDs. When I tried to buy 8193rd convoi (under the default setting i.e. convoys = 8192), Simutrans just shut down. It would be good if there is a warning message, if you tried to buy 8193rd convoi...

Re: Warning to overflow of convoi IDs Reply #3 – March 23, 2009, 02:22:36 pm well, mazbe the default should be 32760 anyway ...But a warning is possible. Same would go for just denz buzing a new one. Quote Selected

Re: Warning to overflow of convoi IDs Reply #5 – March 23, 2009, 03:20:37 pm Vilvoh, just so that you know: that could be easily interpreted as insulting (at least I can imagine that instantly).How much memory does that value eat anyway? 8B per item when aligned? Quote Selected

It's just a table of pointers, which is used to implement the "tombstone" pattern to have checkable pointers (checkable if the object in question still exists).http://en.wikipedia.org/wiki/Tombstone_(programming)Edit:If someone ever wondered what "quickstones" are, that's been a modification of this pattern, which is supposed to be faster. No idea if this is still in the current Simutrans code, but it was when I left it. Quote Selected

Re: Warning to overflow of convoi IDs Reply #8 – March 24, 2009, 12:18:27 pm THe new code will extend to 65530 and give a warning (and no new convoi) when handles are exceeded. Meaning the values will be gone from configuration files soon. Quote Selected
