tracking : Error when srs=4326 and threshold is low #7

Closed Remi-C closed 9 years ago

To reproduce : create a shapefile of type polygon with user_id::text and w_time::text Set the shapefile srs to 4326 (WGS84). WGS84 unit is not meter but degree.

Setting the threshold to 1 or 0.1 or 0,1 slow down conserably the plugin, finally freezing qgis with one CPU fully occuped.

Precision : to reproduce ++ :

set threshold to 1, zoom/dezoom until something is tracked.
Zoom
Change threshold to 0.1
zoom dezoom.
Go to a zoom level of type N:1
set threshold to 1

-> Infinite loop

@yoyonel : can you assign yourself plz, I can't do it

I think it's a temporary bugs (according with our current technology for saving/tracking the position). With the next realease (enqueue task & distributed costs), i'm pretty sure that the bug will vanish ^^

@Remi-C : can i close this one too ?
