InheritedElement.removeDependent() #129210
Conversation
It looks like this pull request may not have tests. Please make sure to add tests before merging. If you need an exemption to this rule, contact Hixie on the #hackers channel in Chat (don't just cc him here, he won't see it! He's on Discord!). If you are not sure if you need tests, consider this rule of thumb: the purpose of a test is to make sure someone doesn't accidentally revert the fix. Ask yourself, is there anything in your PR that you feel it is important we not accidentally revert back to how it was before your fix? Reviewers: Read the Tree Hygiene page and make sure this patch meets those guidelines before LGTMing. |
@goderbauer I've added the test. Please take a look. |
There's a lengthy discussion about exactly this API in #128432, which hasn't reached a conclusion yet and we should hold off on this change until it does. I would encourage you to post your use case there as that seems to be what's still missing: a compelling argument for actually having this API. |
I already have a slightly adjusted version of this PR that actually solves #128432. @goderbauer please let me know if I should create a new PR for that or just push these changes into this one and adjust the description a bit. |
@s0nerik I lost track of this PR and I apologize for the delay. If we actually decide to do this, I would prefer the approach that was outlined in the first few comments of #128432 (i.e. introduce a removeDependency method to complete the existing set of update, get, set methods) instead of adding a separate notification mechanism as implemented in this PR. Is that the change you had in mind with your previous comment? Would you mind pushing that into this PR so we can evaluate that? |
Hey @goderbauer, thanks for reaching out. I've pushed the changes I mentioned before along with some doc comment adjustments for clarity. BTW, I named the method |
