Developer's Report: Firebird Core Development & Coordination
May to August 2015

August 2015
New development:
  • Core support for 32KB page size
  • CORE-4909: MERGE / HASH JOINs produce incorrect results when VARCHAR join keys differ only by trailing spaces
  • CORE-4497: Wrong handling in FOR-cursor when NOT EXISTS( select from <VIEW> ) statement is used to check results obtained from SP
  • Fixed the hash function for in-process compatible locks
July 2015
  • CORE-4872: v3 fbclient cannot work with servers older than v2.5 via the remote protocol
  • CORE-4867: Server crash when preparing a query with PLAN clause at some CTE
  • CORE-4710: invalid request BLR at offset 361 context already in use (BLR error)
  • CORE-4107: wrong resultset (subquery + derived table + union)
  • Fixed hostless INET/WNET connection strings on Linux
  • Fixed the SHOW SEQU output on 64-bit Linux
June 2015
  • CORE-4839: SHOW GRANTS does not display info about exceptions which were granted to user
  • CORE-4618: Rollback doesn`t undo changes when MERGE statement updates the same target rows multiple times and PLAN MERGE is used
  • CORE-4561: BUGCHECK(183) when use cursor with "order by ID+0" and "for update with lock"
  • CORE-4369: BUGCHECK(177) for MERGE with multiple matches
  • Restored the pre-v3 prefetch performance
May 2015
  • CORE-4822: MERGE JOIN cannot be used for DBKEY based expressions
  • CORE-4809: HASH/MERGE JOIN is not used for more than two streams if they are joined via USING/NATURAL clauses and join is based on DBKEY concatenations
  • CORE-4806: Regression: generators can be seen/modified by unprivileged users
  • CORE-4798: Regression: MIN/MAX with a join ignores possible index navigation
  • CORE-4786: Problematic key value (when attempt to insert duplicate in PK/UK) is not shown where length of key >= 127 characters
  • CORE-214: Count ( DISTINCT ... ) is too slow
  • Fixed bad handling of zero-length segments coming from internally filtered blobs
