There was a problem hiding this comment.
instead of sprintf two times for the same id we could just do:
spID := fmt.Sprintf("sp%d", new(maphash.Hash).Sum64())

What did this pull request do?
This test changes
SAVEPOINTnames from relying on the memory address of the callback (which can cause unexpected issues with partial rollbacks), to using a random integer.The integer is generated using
maphash.Hash, which is used as that internally relies onruntime.fastrand, which is the most performant way to get a random integer.I've ensured the test fails without my code changes, and passes with them applied.
Use Case Description
Covered in #7173
