Hi! I’m trying to upgrade the MongoDB Ecto library to be compatible with Ecto 3. I’m seeing a ton of changes I can’t find any reference to in the upgrade docs. Multiple method signatures seem to have changed without any warning or mention. It’s very possible this is all well documented and I’m just looking in the wrong place! It’s also possible the adapter had these errors before and the upgrade to Ecto 3 just caused things to loudly break.
Either way, I’m wondering – besides the 10 bullet points or so here, ecto/CHANGELOG.md at master · elixir-ecto/ecto · GitHub, are there any resources to upgrade an Ecto adapter from Ecto 2 to 3? Does anyone have any tips to migrate the adapter?
The stream function is no longer being passed a preprocessor, but there’s no mention of this breaking change in the upgrade docs. Again, I might be looking in the wrong place!
Another example: DBConnection 2.0 removesensure_all_started and it has no mention in the DB Connection Changelog. In fact, DB Connection 2.0 doesn’t have any upgrade notes for how to upgrade something using 1.0 to 2.0. At least, they’re not in the git repo.
I really love the documentation for elixir and phoenix, so I have to imagine I’m looking in the wrong place. I’m going a bit crazy wondering what’s going on. A “how-to” guide would be great, but I’ll settle for a simple, “We ripped these methods out. Good luck!” Any upgrade guides for DB Connection 1.x to 2.x anyone knows about?
