objchange: set length is unknown with partially known elements#33377
Conversation
If a set contains partially known values the length is unknown which causes assertPlannedObjectValid to fail valid plans. Revert to the old method if using LengthInt for the set lengths, which returns the maximum number of possible elements, with a guard for entirely unknown set values.

There was a problem hiding this comment.
Seems plausible as an interim 1.5 fix!

If a set contains partially known values
Lengthwill be unknown which causesassertPlannedObjectValidto fail valid plans.Revert to the old method if using
LengthIntfor the set lengths, which returns the maximum number of possible elements, with a guard for entirely unknown set values. Improve the check for incorrectly computed objects to catch existing test cases.While technically inaccurate,
LengthIntvalues are not going to fail for valid plans and gives us a minimal fix which can be backported to v1.5. A follow up PR for the development branch will contain a more precise fix using value refinements.fixes #33371
