Constructor - 1 will keep the error code in the BlockNum field -> caller must check if the blockNum is error or not #40

Add the comment in the function to warn the Caller function to check if an error is returned or not in the blockNum field and if so return the appropriate error code back from the caller
Make changes to ALL the caller's of this function to do the error check

gokulsreekumar commented 2 years ago

The callers of this constructor and the following constructors: RecBuffer :: RecBuffer() (Constructor 1), IndBuffer :: IndBuffer() (Constructor 1), IndInternal :: IndInternal() (Constructor1) and IndLeaf :: IndLeaf() (Constructor 1) should check the value of blockNum field to verify if the disk block was allocatted succesfully.

Done, Except for the Indexing part changes. ba_insert() method is the only place where constructor 1 of RecBuffer is being called to allocate a new block.

Basic Idea → It is only called when we need more space

Create Relation → This will boil down to ba_insert calls
Create Index → Not sure about this as of now
Insert (and Importing) Records
- → This directly calls ba_insert
Selecting
- Basically this will be create relation followed by insert records
  - Thus boiling down to ba_insert call
