This is a misuse of MDB_CURRENT: as documented, the new value is supposed to be the same size as the existing value.
No, that's not what the doc says.
"MDB_CURRENT - (...) intended to be used when the new data is the same size as the old. Otherwise it will simply perform a delete of the old record followed by an insert."
I think LMDB should check the size, even if you change the doc to match the code rather than the other way around.
If you want to avoid error checks, I'd rather avoid EINVAL checks like key==NULL which are easier for the user to check than "old size = new size".
