- Added a lot of code comments
- Updated get_best_ror_intersec() to prefer index scan on not clustered keys before clustered keys.
- Use HA_CLUSTERED_INDEX to define if one should use HA_MRR_INDEX_ONLY
- For test of using index or filesort to resolve ORDER BY, use HA_CLUSTERED_INDEX flag instead of primary_key_is_clustered()
- Use HA_TABLE_SCAN_ON_INDEX instead of primary_key_is_clustered() to decide if ALTER TABLE ... ORDER BY will have any effect.

The printing of include stack in the error case in mysqltest omitted the
bottom of the stack (the line number in original test case file), and instead
printed the top of the stack twice. Fix to print each element on the stack
once and only once.
Original code by Zardosht Kasheff
sql/handler.cc:
Added HA_ERR_DISK_FULL and ENOSPC (for handler that uses normal errno).
This sets 'fatal_error' to ensure that the error is logged to err file (which hopefully is on another disk...)
When a view is merged into a select all the depended_from fields
pointing to the select of the view should have been corrected to
point to the select where the view is used. It was not done yet.
This could lead to wrong results returned by queries such as
one from the test case for bug 33389.
Correction of outer references required walking through all items
of the proccesed qurery. To avoid this the following solution was
implemented.
Each select now contains a pointer to the select it is merged into
(if there is any). Such pointers allow to get the corrected value
of depended_from on the fly. The function Item_ident::get_depended_from
was introduced for this purpose.
Fixed alias bug when compiling with gcc 4.2.4 that caused subselect.test to fail

sql/sql_string.h:
Removed alias warnings by changing type from char * to const char*
storage/heap/hp_test2.c:
Removed SAFEMALLOC to get rid of compiler error
Fixed test case as we can't anymore use heap_rlast() on a HASH key entry.
Resolved all conflicts, bad merges and fixed a few minor bugs in the code.
Commented out the queries from multi_update, view, subselect_sj, func_str,
derived_view, view_grant that failed either with crashes in ps-protocol or
with wrong results.
The failures are clear indications of some bugs in the code and these bugs
are to be fixed.
Analysis:
The subquery is evaluated first during ref-optimization of the outer
query because the subquery is considered constant from the perspective
of the outer query. Thus an attempt is made to evaluate the MAX subquery
and use the new constant to drive an index nested loops join.
During this evaluation the inner-most subquery replaces the JOIN_TAB
with a new one that fetches the data from a temp table.
The function select_describe crashes at the lines:
TABLE_LIST *real_table= table->pos_in_table_list;
item_list.push_back(new Item_string(real_table->alias,
strlen(real_table->alias),
cs));
because 'table' is a temp table, and it has no corresponding table
reference. This 'real_table' is NULL, and real_table->alias results
in a crash.
Solution:
In the spirit of MWL#89 prevent the evaluation of expensive predicates
during optimization. This patch prevents the evaluation of expensive
predicates during ref optimization.
sql/item_subselect.h:
Remove unused class member. Not needed for the fix, but noticed now and removed.
storage/maria/ma_loghandler.c:
Added assert if we give wrong type to translog_write_record().
(This should be impossible, but the failure record in buildbot also looks impossible so we need more information...)
storage/maria/ma_loghandler.h:
Added prototype for check_translog_description_table()
storage/maria/unittest/ma_loghandler_examples.c:
Call check_translog_description_table() to register number of log_record_type_descriptor[] events.
- add version info for the client library, dynamic plugins and some utilities
- do not recompile client library sources 3 times (for mysqlclient , mysqlclient_notls and libmysql)
One time is sufficient, so get rid of mysqlclient_notls, and link static client library to the shared.
- remove incremental linking flag
- Fix active lock in freed memory in ha_archive (share mutex was not released prior to free())
- Do not attempt vio_fastsend or vio_keepalive on named pipes and shared memory.
LPBUG#782269 : critical sections are initialized twice in xt_xn_init_db()
LPBUG#782431: active lock in memory released by xt_ind_exit()
LPBUG#782433 : xt_heap_release() does not release spinlock hp->h_lock initialized in xt_heap_new().
LPBUG#782435: xt_exit_row_locks() tries to release unallocated locks
Analysis:
During optimization of the subquery, in the call chain:
update_ref_and_keys -> add_key_fields ->
merge_key_fields -> Item_direct_ref::is_null -> Item_cache::is_null
The call to Item_cache::is_null() returns TRUE, which is wrong.
This results in Item_null replacing the field 'f3' in the KEY_FIELD,
then this Item_null is used for index access, producing a wrong result.
The reason why Item_cache::is_null returns wrong result is that
this Item_cache object is a cache of the left operand of IN, and was
updated in Item_in_optimizer::val_int. In MWL#89 the latter method is
called during the execution phase, which is after we optimize the subquery.
Therefore during the optization phase the left operand cache of IN was
not updated.
Solution:
Update the left operand cache during optimization if it is a constant.
This bug fix also discoveres and fixes a wrong IF statement in
convert_constant_item().
