# This file implements regression tests for SQLite library. The

#
# EVIDENCE-OF: R-36924-43758 By default, every row in SQLite has a
# special column, usually called the "rowid", that uniquely identifies
# that row within the table.

# Test the automatic generation of rowids when the table already contains

# Once the maximum rowid is taken, rowids are normally chosen at
# random. By by reseting the random number generator, we can cause
# the rowid guessing loop to collide with prior rowids, and test the
# loop out to its limit of 100 iterations. After 100 collisions, the
# rowid guesser gives up and reports SQLITE_FULL.
