Upgrade to SQLite 3.30; Django 2.2 requires at least SQLite 3.8.3.

[FlipperPA]

UPDATE: this is unlikely to ever be merged in. Please use the more modern version here: https://github.com/FlipperPA/django-s3-sqlite

This upgrades to the latest/greatest version.

Django 2.2 deploys using SQLite (or the Zappa Django Utils s3sqlite engine) will fail, because the current package is SQLite 3.6.0.

Cheers!

@FlipperPA did you ever get this working? I for the life of me can't.

@youcandanch I'm going to give it another whirl next week. I had it working locally, and wanted to test it as part of Lambda packages, but now it doesn't appear to be working from local. I'm wondering if I missed something, or something was cached.

I'll look into it more deeply next week.

I finally got some time to look at this. It turns out we need to build a full build_static version of SQLite3 with Python, rather than linking to the system version, which would still be 3.7.17 on AWS. I followed the instructions here:

https://charlesleifer.com/blog/compiling-sqlite-for-use-with-python-applications/

This created a much, much larger binary (which makes sense), because it should contain all of SQLite. I've successfully pushed out the binary and have it responding from AWS Lambda with version 3.30:

(pyphilly_venv) [tallen@wrds-pub1-dev-h pyphilly]$ zappa invoke --raw dev "import sqlite3; print(sqlite3.sqlite_version)"

Anyone else care to test? @youcandanch?

@Miserlou @mcrowson @jneves This is now ready to be merged. I've got it running in dev and production on my site at https://pyphilly.org/ with the latest Django and Wagtail versions. Huzzah!

[vaivars]

Is there any progress in merging this?

[FlipperPA]

@vaivars It is unlikely this will every be merged in. You can use https://github.com/FlipperPA/django-s3-sqlite which is now more advanced, with quite a few more checks to help avoid (but not eliminate) race conditions.
