row_rename_table_for_mysql(): Return DB_ERROR instead of DB_SUCCESS
when fil_rename_tablespace() returns an error. This bug was introduced
in the InnoDB Plugin.

Approved by Sunny Bains over IM.

Fixed a misplaced parenthesis, injected due to
syncing from libedit CVS head.

             BREAKS SOURCE RELEASE BUILD

Some of the required files were not getting copied while
performing 'make dist' and hence the build failed for
the created distribution source.

Added the missing files to Makefile.am.

btr_record_not_null_field_in_rec(): Remove the parameter rec.
Use rec_offs_nth_sql_null() instead of rec_get_nth_field().

               USING MYISAM_USE_MMAP ON WINDOWS

When OPTIMIZE/REPAIR TABLE is switching to new data file,
old data file is removed while memory mapping is still
active.

With 5.1 implementation of nt_share_delete() it is not
permitted to remove mmaped file.

This fix disables memory mapping for mi_repair() operations.

storage/myisam/ha_myisam.cc:
  mi_repair*() functions family use file I/O even if memory
  mapping is available.
  
  Since mixing mmap I/O and file I/O may cause various artifacts,
  memory mapping must be disabled.
storage/myisam/mi_delete_all.c:
  Clean-up: do not attempt to remap file after truncate, since
  there is nothing to map.

               WITH LIBEDIT

Libedit won't build on platforms that do not provide
"sys/cdefs.h".

Removed the inclusion of cdefs.h from all files
other that sys.h, which includes this file only
when the header is found while configuring.

Updated libedit library.

hash index at shutdown

btr_search_disable(): Just drop the entire adaptive hash index,
without dropping every record separately.

buf_pool_clear_hash_index(): Renamed and simplified from
buf_pool_drop_hash_index(). Set block->index = NULL for every block in
the buffer pool. Do not release the btr_search_latch. The caller will
have to adjust other data structures.

Remove block->is_hashed. It is redundant, should be always equal to
block->index != NULL.

Remove btr_search_fully_disabled, btr_search_enabled_mutex, and
SYNC_SEARCH_SYS_CONF. We drop the AHI in one pass, without releasing
the btr_search_latch in between.

Replace void* with const rec_t* and add assertions on btr_search_latch
and btr_search_enabled to ha0ha.h, ha0ha.ic, ha0ha.c.

page_set_max_trx_id(): Ignore the adaptive hash index. I forgot to
push this in rb:750.

btr0sea.c: Always after acquiring btr_search_latch, check for
block->index==NULL or !btr_search_enabled. We can now set
block->index=NULL while only holding btr_search_latch in exclusive
mode. Always acquire btr_search_latch before reading block->index,
except in shortcuts when testing for block->index == NULL.

ha_clear(), ha_search(): Unused function, remove.

buf_page_peek_if_search_hashed(): Remove. This function may avoid
latching a page at the cost of doing a duplicate buf_pool->page_hash
lookup.

bug#11766457 - adjusting/modifying the the tests as tests were failing if system time zone is set differently.

Problematic query:
insert ignore into `t1_federated` (`c1`) select `c1` from  `t1_local` a
where not exists (select 1 from `t1_federated` b where a.c1 = b.c1);
When this query is killed in another connection it could lead to crash.
The problem is follwing:
An attempt to obtain table statistics for subselect table in killed query
fails with an error. So JOIN::optimize() for subquery is failed but
it does not prevent further subquery evaluation.
At the first subquery execution JOIN::optimize() is called
(see subselect_single_select_engine::exec()) and fails with
an error. 'executed' flag is set to TRUE and it prevents
further subquery evaluation. At the second call
JOIN::optimize() does not happen as 'JOIN::optimized' is TRUE
and in case of uncacheable subquery the 'executed' flag is set
to FALSE before subquery evaluation. So we loose 'optimize stage'
error indication (see subselect_single_select_engine::exec()).
In other words 'executed' flag is used for two purposes, for
error indication at JOIN::optimize() stage and for an
indication of subquery execution. And it seems it's wrong
as the flag could be reset.

Change the RPM spec file so that each RPM "obsoletes" the corresponding RPMs
of all (other) configurations, so a "server" RPM of any configuration
can replace the "server" RPM of any other configuration on a "rpm -U".

SYSTEM VARIABLE NAME SQL_MAX_JOIN_SI 

BACKGROUND:

ER_TOO_BIG_SELECT refers to SQL_MAX_JOIN_SIZE, which is the
old name for MAX_JOIN_SIZE.

FIX:

Support for old name SQL_MAX_JOIN_SIZE is removed in MySQL 5.6
and is renamed as MAX_JOIN_SIZE.So the errmsg.txt 
and mysql.cc files have been updated and the corresponding result
files have also been updated.

                      CREATE_TIME IN INFORMATION_SC

It was impossible to determine MEMORY table creation time,
since it wasn't stored/exposed.

With this patch creation time is saved and it is available via
I_S.TABLES.CREATE_TIME.

Note: it was decided that additional analysis is required before
implementing UPDATE_TIME. Thus this patch doesn't store UPDATE_TIME.

  Added 'innodb_file_format_check' as variable to ignore change to.
  Tests that had to restore this amended
  Two tests assumed it to be Antelope, make sure these run on a freshly
    started server
  For 5.5, apparently innodb_file_format_max is the one to ignore

Replace part of the patch that Kevin apparently forgot to push.
Fix the bug also in the built-in InnoDB of MySQL 5.1.

I cannot explain why the test case was not failing without the
full patch.

This was rb:762, approved by me.

The problem occurred when indexes are added between the time that an
UNDO record is created and the time that the purge thread comes around
and deletes the old secondary index entries.  The purge thread would
hit an assert when trying to build a secondary index entry for
searching.  The problem was that the old value of those fields were not
in the UNDO record since they were not part of an index when the UPDATE
occured. 
A test case was added to innodb-index.test.

  Added simple cut-off w/warning if > one million lines

               FULLTEXT INDEXES

myisamchk may create incorrect fulltext index for compressed
tables. Incorrect data pointer size was used while creating
fulltext index.

when buffered changes are to be discarded

sync_thread_add_level(level = SYNC_IBUF_INDEX_TREE): Relax a too strict
condition that the thread must not be holding locks below SYNC_FSP_PAGE.
It is perfectly valid to hold any latch above SYNC_IBUF_INDEX_TREE when
acquiring the insert buffer tree latch.

bugs in it - accessing uninitialized ::len member (thanks, Jimmy!)
and a memory leak.

This is a followup to vasil.dimov@oracle.com-20110909070724-jvirxnpkbxieauz5
which disabled the prefetch code.

when buffered changes are to be discarded

ibuf_add_free_page(): Lower the latching order of the newly allocated page
to SYNC_IBUF_TREE_NODE_NEW after latching the insert buffer tree root.

This bug always was bogus UNIV_SYNC_DEBUG alarm. The function
buf_block_dbg_add_level() is a no-op unless UNIV_SYNC_DEBUG is defined.
