MgCooker: Crash on large map bounds

[zspitzer]

using these options causes mg cooker to crash with the lower scales with a system out of memory exception, too many tiles?

scales =[2500, 4766.66548, 9088.43994, 17328.62118, 33039.89619, 62996.05311, 120112.44481, 229014.33798, 436653.89612, 832553.22213, 1587401.08316, 3026643.98126, 5770799.75972, 11002988.81301, 20979026.80047, 40000001.17915, 76266650 ] ; extent =[105.0056, -52.8963,162.1912, -1.503 ];

Fixed in r4335.

When the tiles are generated, a list of all row/column pairs is generated for each scale. When writing the code, I could see that this was inefficient, but I had no space efficient random pair generator.

Now that this has turned out to actually be a problem, I have implemented a less random method, but now the list is limited to keeping 500 pairs at a time (a producer/consumer queue).

Alright, this appears to be a bug in the commandline code?

Could you post your map's bounds?

[zspitzer]

It's the same bounds as in the description.

The GUI just exits without any error message

[ksgeograf]

Fixed with r4464.

This must have been a long standing bug, it was caused by not having all scales in the process.

I could not get the GUI to "just exit", it runs until all tiles are rendered and then exits (is that what you meant?)

[zspitzer]

maybe the just exit was that there isn't a tiling complete message when it finishes?

[ksgeograf]

There is no message stating that it is finished.

Do you prefer one?
