I keep getting error reports from people like this. shit just crashes at pathing.

[jK]

possibly the bug I fixed in master

Gundam uses some specific footprints causing the pathestimator to do an endless loop. Possibly this causes an infinite memalloc.

[smoth]

That is interesting, what footprints and how does that even happen?

[Forboding Angel]

Could you be more specific JK? I am rather interested in this as well.

[Kloot]

possibly the bug I fixed in master

Gundam uses some specific footprints causing the pathestimator to do an endless loop. Possibly this causes an infinite memalloc.

Spring 0.82.7.1 (0.82.7.1)

1) the piece of infinitely-looping code is not in 0.82.7, and does not allocate any memory
2) with Gundam's footprints that loop would be entered on any map, not just "large" ones

The actual cause is again probably just the excessive memory usage when loading 7z archives (http://springrts.com/phpbb/viewtopic.php?f=11&t=25206 et all).

That is interesting, what footprints and how does that even happen?

Within a certain range of master builds, any non-square footprint with one dimension <= 2 (as specified in movedefs.lua) and the other > 2 would result in some loop increment variable being 0 and lock up the path estimator.

[smoth]

The actual cause is again probably just the excessive memory usage when loading 7z archives (http://springrts.com/phpbb/viewtopic.php?f=11&t=25206 et all).

that particular map was released as a sdz because of said bug.

So what would be causing him to have an unwritable pathing dir for specific maps. This is what I keep seeing from random people.

[Kloot]

"Error opening" does not necessarily equal "unwritable", in this context it just means the PE cache-file for that map does not exist (because Spring crashes before reaching the point at which it would be written) and hence cannot be opened for reading.

[smoth]

ah ok, so any idea why this would happen on an sdz for a large map? It does not happen to everyone.
