Bug in Roadmap Code for BPlusTree::bPlusCreate

[Ruben Jacob]

Hi,

In the roadmap code for bPlusCreate, it is not specified to setAttrCatEntry after creating a new root block. Because of this, when we call bPlusInsert, it is checked whether attrCatEntry has a rootblock and E_NOINDEX is returned. Therefore, when we create an index and then drop it, the error message of NO INDEX is seen.

TL;DR 

In bPlusInsert this line:

int blockNum = /* rootBlock of B+ Tree (from attrCatEntry) */;

results in blockNum getting value -1 as we had not set AttrCatEntry with rootBlock in bPlusCreate function.

Yes this is a known issue, we will update this ASAP.
