    docker run -it -p 8001:8001 ubuntu

Then inside that container:

    apt-get install -y python3 build-essential tcl wget python3-pip git python3.8-venv

For each version of SQLite I wanted to test I needed to figure out the tarball URL - for example, for `3.38.0` I navigated to https://www.sqlite.org/src/timeline?t=version-3.38.0 and clicked the ""checkin"" link and copied the tarball link:
https://www.sqlite.org/src/tarball/40fa792d/SQLite-40fa792d.tar.gz

Then to build it (the `CPPFLAGS` took some trial and error):
```
cd /tmp
wget https://www.sqlite.org/src/tarball/40fa792d/SQLite-40fa792d.tar.gz
tar -xzvf SQLite-40fa792d.tar.gz
cd SQLite-40fa792d
CPPFLAGS=""-DSQLITE_ENABLE_FTS3 -DSQLITE_ENABLE_FTS3_PARENTHESIS -DSQLITE_ENABLE_RTREE=1"" ./configure
make
```
Then to test with Datasette:
```
cd /tmp
git clone https://github.com/simonw/datasette
cd datasette
python3 -m venv venv
source venv/bin/activate
pip install wheel # So bdist_wheel works in next step
pip install -e '.[test]'
LD_PRELOAD=/tmp/SQLite-40fa792d/.libs/libsqlite3.so pytest
```

After some trial and error I proved that those tests passed with 3.36.0:
```
cd /tmp
wget https://www.sqlite.org/src/tarball/5c9a6c06/SQLite-5c9a6c06.tar.gz
tar -xzvf SQLite-5c9a6c06.tar.gz
cd SQLite-5c9a6c06
CPPFLAGS=""-DSQLITE_ENABLE_FTS3 -DSQLITE_ENABLE_FTS3_PARENTHESIS -DSQLITE_ENABLE_RTREE=1"" ./configure
make
cd /tmp/datasette
LD_PRELOAD=/tmp/SQLite-5c9a6c06/.libs/libsqlite3.so pytest tests/test_internals_database.py
```
BUT failed with 3.37.0:
```
# 3.37.0
cd /tmp
wget https://www.sqlite.org/src/tarball/bd41822c/SQLite-bd41822c.tar.gz
tar -xzvf SQLite-bd41822c.tar.gz
cd SQLite-bd41822c

Really wish I had a good mechanism for running the test suite against different SQLite versions!

May have to revisit this old trick: https://til.simonwillison.net/sqlite/ld-preload","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",1160407071,
