storage/innobase/handler/handler0alter.cc:
for NEWDATE key_type says unsigned, thus col->prtype says unsigned,
but field->flags says signed. Use the same flag for value retrieval
that was used for value storage.
The error is due to conflict between min/max macros in my_global.h
and system header < limits>, indirectly included via generated
probes_mysql_dtrace.h
Temporarily undefined min/max for the inclusion of the probes_mysq_dtrace.h
The comment for the fix commit says:
Due to the changes required by ICP we first copy a row from the InnoDB
format to the MySQL row buffer and then copy it to the pre-fetch queue.
This was done for the non-ICP code path too. This change removes the
double copy for the latter.
For single table update/insert added deep check of single tables (single_table_updatable()).
For multi-table view insert added additional check of target table (check_view_single_update).
Multi-update was correct.
Test suite for all cases added.

(bug #11765850 - 58854).
Here's the comment of the patch commit:
The bug is that the InnoDB pre-fetch cache was not being used in
row_search_for_mysql(). Secondly the changeset that planted the
bug also introduced some inefficient code. It would read an extra
row, convert it to MySQL row format (for ICP==off), copy the row
to the pre-fetch cache row buffer, then check for cache overflow
and dequeue the row that was pushed if there was a possibility of
a cache overflow.
The reason for the failure is that the loaded library has the same exported symbols
as the builtin one. So the plugin uses innodb functions e.g srv_boot from mysqld
rather than plugin's own. This causes the crash.
On Unix systems with gcc4 later this error was so far worked around using GCC's
visibility attribute. However, in our case, we're using gcc3.

The fix is to restrict symbol visibility in the plugin using version script
(called map file on Solaris).
- If LooseScan is used with quick select, require that quick select produces
data in key order (this disables use of MRR, which can return data in arbitrary order).
in normal blocking style, then later do a non-blocking operation.
In this case, the vio->async_context was not set up correctly, so that
non-blocking operation was not properly handled.
When working on MWL#247 I forgot to adjust the function create_hj_key_for_table()
that created a key definition for hash join keys. The modified function must
set the values of the fields ext_key_parts, ext_key_flags, ext_key_part_map
added to the key definition structure in MWL#247.
The line in the file_contents.test removes all the '/lib' substrings from the
path, so file cannot be found if a path contains such a substring.
As i didn't find where it is needed, the line was just removed

no '/lib' substring cutting.

by Sergey Petrunia when working on the problems concerning outer joins within
in subqueries converted to semi-joins.
