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

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.
modified function do_get_error in mysqltest.cc to handle multiple variable passed
added test case to mysqltest.test to verify handling to multiple errors passed
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.
This patch corrects a defect whereby the bootstrap_server() method was
returning 0 instead of the error code generated. The code has been changed to
return the correct value returned from the bootstrap command.
This patch corrects a defect in the building of the DELETE commands for
disabling a plugin whereby only the original plugin data was deleted. If there
were other plugins, the delete did not remove the rows. The code has been
changed to remove all rows from the mysql.plugin table that were inserted when
the plugin was loaded. The test has also been changed to correctly identify if
all rows have been deleted.
warnings are converted to errors, the compiler complains about
the fact that binlog_can_be_corrupted is defined but never used.
We need to check if this is a dead code or if someone removed any
code by mistake.
When temporary tables is used for result sorting
result field for gconcat function is created using
group_concat_max_len size. It leads to result truncation
when character_set_results is multi-byte character set due
to insufficient tmp table field size.
The fix is to increase temporary table field size for
gconcat. Method make_string_field() is overloaded
for Item_func_group_concat class and uses
max_characters * collation.collation->mbmaxlen size for
result field. max_characters is maximum number of characters
what can fit into max_length size.
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.

Sun Studio 12 has an error when calculating the compile-time
length of a constant character string. The error is only
present when building an optimized 32-bits version, using
the -xbuiltin=(%all) compiler flag.
During compilation, the compiler recognizes the use of
the strlen() function used on a constant string. It
optimizes the strlen and replaces it with the actual
length of the string. This optimization seems to
calculate the length wrongly in this particular case.
Replacing the "const char *" with a "const char []"
solves the problem.
This is a redo for 5.5
Added 'innodb_file_format_max' 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
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".
