Sqlite_readonly_exception crash updated

marius — Wed, 22 Mar 2017 05:13:24 GMT

Hello,

While trying to migrate the app from 10.2.5 to 100 I've started to get lots of crashes with "Esri_runtimecore::Common::Sqlite_readonly_exception:". They happen when you're browsing the map or you're interacting with the map. The map has a simple basemap (Streets Vector) and a couple of AGSGraphicsOverlays. The map has a touchDelegate set to self.

Is this a known issue? Do you have any hints where I should start looking?

Thank you,

Marius

Next day edit:

I'm trying to get more info on what's causing this issue. So far, it seems to be a race condition when interacting with the map while the map is downloading. I can reproduce it pretty easily by quickly moving the map around while the map is loading. Performing the same interactions after the map is loaded (2-3 seconds later) does not seem to crash the app.

I've got some call trees from Instruments, but I'm pretty sure they are not the cause of the crash.

Is there any way I can get you some debug info? Log files? Is there any way to set the vector map cache store to memory?

Hi Marius,

Could you do a quick test?

Swap your vectorTiled basemap for a normal tiled one and see if it still crashes.

regards,

David

There was a known issue with vector tiles that prevented users from using the map reliably before all the tiles in view were rendered. This has been fixed for the upcoming release.

David: swapping the map with a tiled one solves the issue. Thank you for that suggestion.

Divesh: Thank you for confirming that. Is there a beta release coming soon?
