Research direction

Start by comparing the documented virtual environment install commands with requirements.txt and the package dependency metadata, then check how the project installs Peewee. Confirm whether a fresh environment installs Peewee 4 despite the pinned version in requirements.txt, and identify the smallest fix that makes the documented installation use a compatible version. Done means the documented commands produce an installation that can import SqliteExtDatabase.

Description

In section Python virtual environment (Linux, BSD and Mac), the installation instructions are :

virtualenv -p python3 venv
source venv/bin/activate
pip install etesync-dav

But doing this at the moment will result in the following

$ virtualenv -p python3 venv
created virtual environment CPython3.12.15.final.0-64-x86_64 in 159ms
  creator CPython3Posix(dest=/tmp/venv, clear=False, no_vcs_ignore=False, venv_redirect=None, global=False)

As you see, this is pulling peewee-4.5.3, when the requirements.txt file mentions peewee==3.14.8.

The problem is that, with peewee in version > 4.0, there are issues with the use of SqliteExtDatabase as they appear in this log message.

[2026-11-12 17:44:39 +0100] [11004/Thread-9 (process_request_thread)] [ERROR] An exception occurred during PROPFIND request on '/ptoret/1AqQIDFUjPMsR6Caxmxp1u_LlDZ7XBOq/': cannot import name 'SqliteExtDatabase' from 'playhouse.sqlite_ext' (/home/pat/Code/etesync-dav/venv/lib/python3.12/site-packages/playhouse/sqlite_ext.py)

This is documented in https://github.com/coleifer/peewee/issues/3041.

Maybe something like https://github.com/ActivityWatch/aw-core/pull/133/changes/40508b9f6ed0e0a4f6ffb0a22b27158a6d333510 could be used to avoid having this kind of errors ?

Meanwhile, what seems to work is to do venv/bin/pip install -r requirements.txt right before venv/bin/pip install etesync-dav. In that case I end up with peewee-3.14.8.

Not sure what is the best way to solve this.
