When we insert a record into MYISAM table which is almost 'full',
we first write record data in the free space inside a file, and then
check if we have enough space after the end of the file.
So if we don't have the space, table will left corrupted.
Similar error also happens when we updata MYISAM tables.
Fixed by modifying write_dynamic_record and update_dynamic_record functions
to check for free space before writing parts of a record
BitKeeper/etc/ignore:
Added libmysql_r/client_settings.h libmysqld/ha_blackhole.cc to the ignore list
myisam/mi_dynrec.c:
Bug #31305 myisam tables crash when they are near capacity.
now we check space left in table in write_dynamic_record
and update_dynamic_record functions.
If we don't have enough room for the new (updated) record, return with the
error.

After adding an index the <VARBINARY> IN (SELECT <BINARY> ...)
clause returned a wrong result: the VARBINARY value was illegally padded
with zero bytes to the length of the BINARY column for the index search.
(<VARBINARY>, ...) IN (SELECT <BINARY>, ... ) clauses are affected too.
sql/item.cc:
Fixed bug #28076.
The Item_cache_str::save_in_field method has been overloaded
to check cached values for an illegal padding before the saving
into a field.
sql/item.h:
Fixed bug #28076.
The Item_cache_str::is_varbinary flag has been added and the
Item_cache_str::save_in_field method has been overloaded to prevent
cached values from an illegal padding when saving in fields.
The signature of the Item_cache::get_cache method has been
changed to accept pointers to Item instead of Item_result
values.

The Item_in_optimizer::fix_left method has been modified to

UNIQUE (eq-ref) lookups result in table being considered as a "constant" table.
Queries that consist of only constant tables are processed in do_select() in a
special way that doesn't invoke evaluate_join_record(), and therefore doesn't
increase the counters join->examined_rows and join->thd->row_count.
The patch increases these counters in this special case.
NOTICE:
This behavior seems to contradict what the documentation says in Sect. 5.11.4:
"Queries handled by the query cache are not added to the slow query log, nor
are queries that would not benefit from the presence of an index because the
table has zero rows or one row."
No test case in 5.0 as issue shows only in slow query log, and other counters
can give subtly different values (with regard to counting in create_sort_index(),
synthetic rows in ROLLUP, etc.).
sql/sql_class.h:
add documentation for some variables
sql/sql_select.cc:
Don't forget const tables when counting read records!

partitioned table
Post-merge fix
A new need for lex initialization arose.
sql/ha_ndbcluster.cc:
Bug#31210 - INSERT DELAYED crashes server when used on
partitioned table
Initialized lex for later use in open_table().
in mysql_creata_like_table() we 'downcase' the complete path to the
.frm file. It works fine in standalone case as there usually
we only have './' as a path to the datahome, but doesn't work in
the embedded server where we add the real path there, so if a
directory has uppercase letters in it's name, it won't be found.
Fixed by 'downcasing' only database/table pair.
sql/sql_table.cc:
Bug #32063 "create table like" works case-significant only in "embedded" server (libmysqld)
do not lowercase the database directory

BETWEEN was more lenient with regard to what it accepted as a DATE/DATETIME
in comparisons than greater-than and less-than were. ChangeSet makes < >
comparisons similarly robust with regard to trailing garbage (" GMT-1")
and "missing" leading zeros. Now all three comparators behave similarly
in that they throw a warning for "junk" at the end of the data, but then
proceed anyway if possible. Before < > fell back on a string- (rather than
date-) comparison when a warning-condition was raised in the string-to-date
conversion. Now the fallback only happens on actual errors, while warning-
conditions still result in a warning being to delivered to the client.
mysql-test/r/select.result:
Show that we compare DATE/DATETIME-like strings as date(time)s
now, rather than as bin-strings.
Adjust older result as "2005-09-3a" is now correctly seen as
"2005-09-3" + trailing garbage, rather than as "2005-09-30".

warning for at that. Preamble doxygenized.

Problem: the table's INDEX and DATA DIR was taken
directly from the table's first partition.
This allowed rename attack similar to
bug#32111 when ALTER TABLE REMOVE PARTITIONING
Solution: Silently ignore the INDEX/DATA DIR
for the table. (Like some other storage engines
do).
Partitioned tables do not support DATA/INDEX
DIR on the table level, only on its partitions.

INDEX DIR, only its partitions do)
