Ensure repository deletion is consistent #6214
Conversation
This change improves the consistency of Pool.remove_repository() to make it easier to write poetry plugins which mutate the repository pool. 1. Deleting an element from the middle of Pool()._repositories decrements the index of later entries. Update Pool()._lookup to reflect this. 2. If a primary repository is deleted, decrement Pool()._secondary_start_idx to ensure that any additional primary repositories are still added before all secondary repositories. 3. If the default repository is deleted, reset Pool()._default so a new one can be added.

@neersighted Any chance this can get backported to the 1.2 branch, since it's a useful improvement to the new plugin functionality? |
1.1 is only accepting backports for critical regressions, and future backports will be for major regressions only. One could argue it's a correctness/soundness fix that deserves to make it into 1.2, but it's a higher risk change and I don't want to delay the 1.2 release unless @radoering and @dimbleby are confident in it. Given 1.2 is reaching stabilization, this will likely make it in 1.3, unless we believe it is a blocker for 1.2 |
|
As far as i can tell, poetry itself never calls remove_repository(), so this would just be a change that affects plugins -- and i would definitely make the correctness/soundness argument since the function's existing behavior leaves the pool in an inconsistent state in many circumstances. |

It's understandable that folk would ask for backports given the enormous amount of time that it has taken to release 1.2 - that sets expectations about when the next release will happen. But a much better thing would be for the project to shift to a mode where it released a lot more frequently. As it goes I agree that poetry itself never even calls the method being changed, so it is unlikely to break anything, so "OK fine" is probably a safe answer for this one. Still I would much prefer the answer to be "no, but we promise that the next release will follow shortly"...! |

The intention is definitely for frequent minor releases with patch releases only for major regressions that make the previous minor unusable compared to its predecessor version. Please don't get scared of 'wait for 1.3' as that is intended to be short -- 1.2 was only heroic to release because of the multi-year gap and massive code churn. I'm still open for arguments for inclusion in 1.2 even if I agree with @dimbleby and would prefer to see this in 1.3. |
|
Since it's a simple bugfix not adding new functionality, it's test coverage is quite good and it's not even used in poetry itself (lowest possible risk), I'd have no problem to accept a 1.2 backport after this PR is merged. However, I have no strong feelings about it. |
