Refine stability rules for diesel release #4503
Conversation
This commit explicitly outlines that we might perform otherwise considered breaking changes in minor releases if that's required by build breaking changes from the rust project itself. A previous example of such a change that nearly required us to make such a breaking change in diesel is the change to default to `resolver = "2"` with the 2021 edition. I rather want to make sure that we don't end up in a similar situation in the future that requires us to issue a new major diesel version just to sidestep0breakage from their side.

To give a worse-case ETA here: I'd like to look a tiny bit further into this, but I'm currently on holidays for the next 15 days, and I don't know that I'll be able to dedicate that time by then. |

No worries, that's something I want to have in place for the diesel 2.3 release, so there is no pressure to merge this soon. |

@Ten0 This is a gentle ping, I still would like to move this forward to just have something in place for the worst case that gives us a few more options to handle things reasonable. |
There was a problem hiding this comment.
Apologies, I'm finding it hard to dedicate time to this.
I guess the main question is what is defined as a breaking change and what kind of breaking change we ultimately want to allow but I guess this is a question that can be answered practically when considering the relevant potential change, so let's just go ahead and merge this if you're confident that's what we should do. 🙂

No worries for taking time to think about this. I should likely also add that I do not want to ever use this. I mostly see this as last resort option that could be meaningful if it only affects a small part of the user base or are really easy to fix. (E.g. if you write this specific generic code you might need to add a |
