This fix reverts patch for bug 33699 and reverts the UPDATE of NOT NULL field with NULL query to old behavior. mysql-test/extra/rpl_tests/rpl_extraMaster_Col.test: Bug #39265: fix for the bug 33699 should be reverted mysql-test/include/ps_modify.inc: Bug #39265: fix for the bug 33699 should be reverted mysql-test/r/auto_increment.result: Bug #39265: fix for the bug 33699 should be reverted mysql-test/r/csv_not_null.result: Bug #39265: fix for the bug 33699 should be reverted mysql-test/r/null.result: Bug #39265: fix for the bug 33699 should be reverted mysql-test/r/ps_2myisam.result: Bug #39265: fix for the bug 33699 should be reverted mysql-test/r/ps_3innodb.result: Bug #39265: fix for the bug 33699 should be reverted mysql-test/r/ps_4heap.result: Bug #39265: fix for the bug 33699 should be reverted mysql-test/r/ps_5merge.result: Bug #39265: fix for the bug 33699 should be reverted mysql-test/r/warnings.result: Bug #39265: fix for the bug 33699 should be reverted mysql-test/suite/ndb/r/ps_7ndb.result: Bug #39265: fix for the bug 33699 should be reverted mysql-test/suite/rpl/r/rpl_extraColmaster_innodb.result: Bug #39265: fix for the bug 33699 should be reverted mysql-test/suite/rpl/r/rpl_extraColmaster_myisam.result: Bug #39265: fix for the bug 33699 should be reverted mysql-test/suite/rpl/t/rpl_err_ignoredtable.test: Bug #39265: fix for the bug 33699 should be reverted mysql-test/t/auto_increment.test: Bug #39265: fix for the bug 33699 should be reverted mysql-test/t/csv_not_null.test: Bug #39265: fix for the bug 33699 should be reverted mysql-test/t/null.test: Bug #39265: fix for the bug 33699 should be reverted mysql-test/t/warnings.test: Bug #39265: fix for the bug 33699 should be reverted sql/sql_update.cc: Bug #39265: fix for the bug 33699 should be reverted
