  Was because of buffer overrun in XCLCOL::ReadColumn.
  The Cbuf buffer was unconditionally filled Now it is limited to its size.
  This happened because this buffer was allocated according to the XCOL
  column size. It is now allocated according to the source column size.

  tells CONNECT to return exact record numbers on info queries. If OFF
  it just gives an estimate. In version 10.0.13 this was unconditionally
  ON and caused info queries on remote tables to be extremely long and
  was the subject of MDEV-6612.

  them sorted by file position. Firstly a new value is stored in indexes
  to know if they are sorted, preventing to do the sorting when it is not
  needed. Secondly, almost all in now done in connect instead of being
  done by the different file access method classes. This pepares the future
  use of temporary files for all table types and also fix the bug that was
  occuring when partially using a multi-column index because of false MRR
  like call of position followed by unsorted rnd_pos no more using indexing.

The version previous to this one is a preliminary test version and
should not be distributed.

- Handle indexed UPDATE/DELETE. Previously this was just tested and
  an error message send when it could not be done. Now CONNECT can
  do it in all the cases. It is done by a MRR like tchnique by making
  a list of all update or delete to do, sort them, then execute them.

Reverted addition to the original patch:
InterlockedExchangeAcquire and InterlockedAndRelease are
supported only on Itanium-based systems.

This is an addition to the original patch. On Windows
InterlockedExchange implies full memory barrier, whereas
only acquire/release barriers required.

MDEV-6340 Mariadb 10.0.12 fatal "Lost connection" error w/ GCC 4.9 'Release' build; workaround ~ CFLAGS="-fno-delete-null-pointer-checks"

don't use attribute nonnull for arguments that can be null

buf0flu.cc line 549.

Analysis: If buf_page_get_state(bpage) == BUF_BLOCK_REMOVE_HASH then
buf_page_in_file(bpage) might not be true. 

Fix: ut_a(buf_page_in_file(bpage) || buf_page_get_state(bpage) == BUF_BLOCK_REMOVE_HASH);

There was a race condition in lock_table_names() which didn't properly test for CREATE OR REPLACE for slaves.


sql/sql_parse.cc:
  Copy create_info flags to thd for lock_table_names()
