Browse Source 
Revert main parts of patch for online index builds. Should be done differently
Added support for %lx in my_snprintf()


sql/ha_myisam.cc:
  Don't enable HA_EXTRA_WRITE_CACHE if too few rows
sql/handler.h:
  Indentaion fix
sql/mysql_priv.h:
  Removed real_alter_table, mysql_add_column and mysql_drop_column
sql/sql_class.cc:
  After merge fix
sql/sql_insert.cc:
  Don't user bulk_insert if only one row (common case)
sql/sql_parse.cc:
  Added mysql_create_index() and mysql_drop_index() as these are only wrappers for mysql_alter_table()
sql/sql_table.cc:
  Revert main parts of patch for online index builds
  Changed back to use tabs to make merges possible between trees
sql/unireg.cc:
  Added comments and minor cleanup
strings/my_vsnprintf.c:
  Added support for %lx.
  Proper long support
