Subject: Bug#44834 strxnmov is expected to behave as you'd expect The problem:
 described in the bug report. The fix: --increase buffers where it's necessary
   (buffers which are used in stxnmov) --decrease buffer lengths which are
 used

client/mysql.cc:
  --increase buffers where it's necessary
    (buffers which are used in stxnmov)
  --decrease buffer lengths which are used
    as argument for strxnmov function
sql/ha_ndbcluster.cc:
  --increase buffers where it's necessary
    (buffers which are used in stxnmov)
  --decrease buffer lengths which are used
    as argument for strxnmov function
sql/ha_ndbcluster_binlog.cc:
  --increase buffers where it's necessary
    (buffers which are used in stxnmov)
  --decrease buffer lengths which are used
    as argument for strxnmov function
sql/handler.cc:
  --increase buffers where it's necessary
    (buffers which are used in stxnmov)
  --decrease buffer lengths which are used
    as argument for strxnmov function
sql/log.cc:
  --increase buffers where it's necessary
    (buffers which are used in stxnmov)
  --decrease buffer lengths which are used
    as argument for strxnmov function
sql/mysqld.cc:
  removed unnecessary line
sql/parse_file.cc:
  --increase buffers where it's necessary

  --increase buffers where it's necessary
    (buffers which are used in stxnmov)
  --decrease buffer lengths which are used
    as argument for strxnmov function

    (buffers which are used in stxnmov)
  --decrease buffer lengths which are used
    as argument for strxnmov function
sql/sql_rename.cc:
  --increase buffers where it's necessary
    (buffers which are used in stxnmov)
