325373747 MDExOlB1bGxSZXF1ZXN0MTg5NzIzNzE2 280 Build Dockerfile with recent Sqlite + Spatialite 565628 closed 0     10 2018-05-22T16:33:50Z 2018-06-28T11:26:23Z 2018-05-23T17:43:35Z CONTRIBUTOR simonw/datasette/pulls/280

This solves #278 without bloating the Dockerfile too much, the image size is now 495MB (original was ~240MB) but it could be reduced significantly if we only copied the output of the compilation of spatialite and friends to /usr/local/lib, instead of the entirety of it however that will take more time.

In the python code change references to import sqlite3 to import pysqlite3 and it should use the compiled version of sqlite3.23.1. You don't need to try/except because pysqlite3 falls back to builtin sqlite3 if there is no compiled version.
