  90. 3582c8f If an OOM error occurs just after obtaining a shared lock on the database file, release the lock before returning. (CVS 6795) by danielk1977 ยท 17 years ago

  92. 641a0bd If after obtaining an exclusive lock to rollback a hot-journal file it is found that the journal file has been deleted, do not return an SQLITE_BUSY error. Just downgrade the lock and continue with the current operation. This eliminates a spurious SQLITE_BUSY error caused by a race condition. (CVS 6792) by danielk1977 ยท 17 years ago
  93. d6bee21 If a call is made to sqlite3PagerAcquire when there are no outstanding references to any pages and the pager is in the error-state, try to exit the error-state at this point.
