Minibase To Do Page - Grossly Outdated..

General

• Check and make sure that the AM pages are all bigger than the DATASIZE of a page - recsize
• On entering values (utility functions) "5" with a space after it is not the same as "5". Need to fix the type checking & atoi algorithm.
• Prompt the user for the working directory. This is where all the databases will be. Problem solved differently
• Doing joins on empty relations can crash:
  select emp.ename, dept.dname
  from emp, dept
  where emp.ename = "John" and emp.did = dept.did;
  
• The answer tuple's fields do not always correspond to the query:
  select e.did, d.dname
  from Emp e, Dept d
  where e.did = d.did;
  {toy, 3}
• Buffer Manager Free Page should NOT put page on free list before checking pin count.
• Change linearHash Tests gen_rec back to the original one. Don't think that I was crazy by using the very simple one, but I was having all sorts of purify errors and I was getting desperate. Then the errors all fixed themselves, so we can go back.
• Use LinearHashingFile::destroyFile(void) as the basis for scanning the entire Linear Hash index.

Catalogs

• create.C = Line 72 = checking tuple size doesn't really work
• Catalog info is stored as tuples. But all the work in the catalog calls is done as structs. This is not a problem, but if we had known more about the final product, we might have rewritten things to make it a little clearer.
• Load doesn't work yet (should be a very minor change)
