Flask-PyMongo 2.0

[dcrosta]

TL;DR:

• Flask-PyMongo 2.0.0b1 is available on PyPI (use pip install --pre ...; docs here)
• It is not backwards incompatible. You must use a URI to configure it (app.config["MONGO_URI"] = ...)
• Tentative release date July 1, 2018
  ** If you don't have time to update your app to use a URI by then, pin down to version 0.5.2 in your requirements

Keeping up with PyMongo and MongoDB developments has been a continual struggle for me as maintainer of Flask-PyMongo, as attested to by the long list of bugs filed. I have let down those who use this project, and I apologize for that.

In order to make the maintenance load acceptable, I have decided to release version 2.0 which will remove all of the "split out" configuration functionality. In 2.0, Flask-PyMongo will only read a MongoDB connection URI from Flask config. For cases where some configuration cannot be passed via URI, it will also accept keyword arguments, which will be passed directly to PyMongo.

I anticipate that this will require changes from many users of Flask-PyMongo, and I apologize for the disruption. I believe that this direction will enable me to keep up with compatibility requests, reduce the number of custom forked versions, and provide a more compact and stable platform for future development.

If you have not yet done so, please pin your version of Flask-PyMongo to the current version (e.g. flask-pymongo<2.0 in a requirements.txt file).

I will try to answer any questions that may come up in this thread until (and likely slightly after) the release of 2.0.

When in time do you see a version 2.0 being ready for testing?
Also, since I use flask-pymongo for several projects I would also like to offer my help in making version 2.0 a reality.

I hope to have an RC ready some time in June. Unlike with past releases, I'm planning to do at least one rc release before 2.0, to let folks have a chance to experiment with it and get some feedback. That might add another month to the cycle, just to ensure that we've had an adequate chance to find any major issues before cutting 2.0.

For anyone interested in following along with development, I've started a branch https://github.com/dcrosta/flask-pymongo/tree/two-point-oh

@hbldh and anyone else here, if you want to live on the bleeding bleeding edge, there's now a probably-working version on branch two-point-oh. I hope to push that, or something substantially like it, to PyPI as 2.0.0b1 within the next week, I just need to convince myself a bit more that it works. (Feedback from others will help speed this along, of course!)
