already been accessed in the buffer pool, do not attempt to merge
buffered changes.

 trx_undo_prev_version_build() should confirm existence of inherited (not-own) external pages.

Bug #14676084 : ROW_UNDO_MOD_UPD_DEL_SEC() DOESN'T NEED UNDO_ROW AND UNDO_EXT INITIALIZED
 mtr script could hit the assertion error !bpage->file_page_was_freed using this path.
 So, also fixed

Description: Null merge from 5.1 to 5.5

Description: Updated yassl to version 2.2.2

When a binlog is replayed into a server, e.g.:
  $ mysqlbinlog binlog.000001 | mysql
it sets a pseudo slave mode on the client connection in order to server
be able to read binlog events, there is, a format description event is
needed to correctly read following events.
Also this pseudo slave mode applies to the current connection
replication rules that are needed to correctly apply binlog events.

If a binlog dump is sourced on a connection, this pseudo slave mode will
remains after it, what will apply unexpected rules from customer
perspective to following commands.

Added a new SET statement to binlog dump that will unset pseudo slave
mode at the end of dump file.

      A patch is pushed on this bug. A result mismatch
      occured for the test main.ddl_i18n_utf8 in

             MYSQLDUMP OUTPUT

Problem: mysqldump when used with option --routines, dumps
         all the routines of the specified database into
         output. The statements in this output are written
         in such a way that they are version safe using C
         style version commenting (of the format
         /*!<version num> <sql statement>*/). If a semicolon
         is present right before closing of the comment in
         dump output, it results in a syntax error while
         importing.


Solution: Version comments for dumped routines are
          specifically to protect the ones older than 5.0.
          When the import is done on 5.0 or later versions,
          entire create statement gets executed as all the
          check conditions at the beginning of the comments
          are cleared. Since the trade off is between the
          performance of newer versions which are more in
          use and protection of very old versions which are
          no longer supported, it is proposed that these
          comments be removed altogether to maintain
          stability of the versions supported.

This bug is fixed by Bug#14251529. Only testcase from the 
contribution is used.

Our dealing of buf_page_t::access_time flag is inaccurate.
* If LRU eviction has not started we don't set the access_time
* If LRU eviction is started we set it only if the block is not
'too old'.
* Not a correctness issue but we hold buf_pool::mutex when
setting the flag

This patch fixes this by:
* Setting flag unconditionally whenever the first page access happens
* Use buf_page_t mutex to protect write to the flag

              INC_HOST_ERRORS() IS CALLED.

Remove a bogus debug assertion.

CHAR(n) in ROW_FORMAT=REDUNDANT tables is always fixed-length
(n*mbmaxlen bytes), but in the temporary file it is variable-length
(n*mbminlen to n*mbmaxlen bytes) for variable-length character sets,
such as UTF-8.

The temporary file format used during index creation and online ALTER
TABLE is based on ROW_FORMAT=COMPACT. Thus, it should use the
variable-length encoding even if the base table is in
ROW_FORMAT=REDUNDNAT.

dtype_get_fixed_size_low(): Replace an assertion-like check with a
debug assertion.

rec_init_offsets_comp_ordinary(), rec_convert_dtuple_to_rec_comp():
Make this an inline function.  Replace 'ulint extra' with 'bool temp'.

rec_get_converted_size_comp_prefix_low(): Renamed from
rec_get_converted_size_comp_prefix(), and made inline. Add the
parameter 'bool temp'. If temp=true, do not add REC_N_NEW_EXTRA_BYTES.

rec_get_converted_size_comp_prefix(): Remove the comment about
dict_table_is_comp(). This function is only to be called for other
than ROW_FORMAT=REDUNDANT records.

rec_get_converted_size_temp(): New function for computing temporary
file record size. Omit REC_N_NEW_EXTRA_BYTES from the sizes.

rec_init_offsets_temp(), rec_convert_dtuple_to_temp(): New functions,
for operating on temporary file records.

 - no need to use --skip-ndb in collections files anymore, since long but
  more clear logic after recent mtr.pl fixes. ndb tests are never run in MySQL Server
  unless explicitly requested
 - remove sys_vars.ndb_log_update_as_write_basic.test and sys_vars.ndb_log_updated_only_basic.result since MySQL Server does not have those
  options.
 - Only sys_vars.have_ndbcluster_basic left since MySQL Server has that variable hardcoded.

When master and slave have different schemas, in particular different
AUTO_INCREMENT columns, INSERT_ID events logged for a given table on
master may be applied to a different table on slave on SBR, e.g.:
  master has one table (t1) with one auto-inc column and another table
  (t2) without auto-inc column, on slave t1 does not have auto-inc
  column (despite having the same columns) and t2 has a auto-inc
  column. The INSERT_ID that is intended for t1, since t1 on slave
  doesn't have auto-inc column is used on t2, causing consistency
  problems.

To fix this incorrect behaviour, auto-inc interval allocation via
INSERT_ID is made effectively terminated at the end of top-level
statements on slave and binlog replay.

Problem description: Incorrect key file. Key file is corrupted,
while reading the keys from the file. The problem here is that 
keyseg->start (which should point to the beginning of a field) 
is pointing beyond total record length.

Fix: If keyseg->start is greater than total record length then 
return error.
