      MDEV-16372 ER_BASE64_DECODE_ERROR upon replaying binary log via mysqlbinlog --verbose · feac078f
      Andrei Elkin authored
      (This commit is exclusively for 10.1 branch, do not merge it to upper ones)
      
      In case of a pattern of non-STMT_END-marked Rows-log-event (A) followed by
      a STMT_END marked one (B) mysqlbinlog mixes up the base64 encoded rows events
      with their pseudo sql representation produced by the verbose option:
            BINLOG '
              base64 encoded data for A
              ### verbose section for A
              base64 encoded data for B
              ### verbose section for B
            '/*!*/;
      In effect the produced BINLOG '...' query is not valid and is rejected with the error.
      Examples of this way malformed BINLOG could have been found in binlog_row_annotate.result
      that gets corrected with the patch.
      
      The issue is fixed with introduction an auxiliary IO_CACHE to hold on the verbose
      comments until the terminal STMT_END event is found. The new cache is emptied
      out after two pre-existing ones are done at that time.
      The correctly produced output now for the above case is as the following:
            BINLOG '
              base64 encoded data for A
              base64 encoded data for B
            '/*!*/;
              ### verbose section for A
              ### verbose section for B
      
      Thanks to Alexey Midenkov for the problem recognition and attempt to tackle,
      Venkatesh Duggirala who produced a patch for the upstream whose
      idea is exploited here, as well as to MDEV-23077 reporter LukeXwang who
      also contributed a piece of a patch aiming at this issue.
      
      Extra: mysqlbinlog_row_minimal refined to not produce mutable numeric values into the result file.

      MDEV-23557 Galera heap-buffer-overflow in wsrep_rec_get_foreign_key · df07ea0b
      sjaakola authored
      This commit contains a fix and extended test case for a ASAN failure
      reported during galera.fk mtr testing.
      The reported heap buffer overflow happens in test case where a cascading
      foreign key constraint is defined for a column of varchar type, and
      galera.fk.test has such vulnerable test scenario.
      
      Troubleshoting revealed that erlier fix for MDEV-19660 has made a fix
      for cascading delete handling to append wsrep keys from pcur->old_rec,
      in row_ins_foreign_check_on_constraint(). And, the ASAN failuer comes from
      later scanning of this old_rec reference.
      
      The fix in this commit, moves the call for wsrep_append_foreign_key() to happen
      somewhat earlier, and inside ongoing mtr, and using clust_rec which is set
      earlier in the same mtr for both update and delete cascade operations.
      for wsrep key populating, it does not matter when the keys are populated,
      all keys just have to be appended before wsrep transaction replicates.
      
      Note that I also tried similar fix for earlier wsrep key append, but using
      the old implementation with pcur->old_rec (instead of clust_rec), and same
      ASAN failure was reported. So it appears that pcur->old_rec is not properly
      set, to be used for wsrep key appending.
      
      galera.galera_fk_cascade_delete test has been extended by two new test scenarios:
      * FK cascade on varchar column.
        This test case reproduces same scenario as galera.fk, and this test scenario
        will also trigger ASAN failure with non fixed MariaDB versions.
      * multi-master conflict with FK cascading.
        this scenario causes a conflict between a replicated FK cascading transaction
        and local transaction trying to modify the cascaded child table row.
        Local transaction should be aborted and get deadlock error.
        This test scenario is passing both with old MariaDB version and with this
        commit as well.
