message:
Followup to Bug#51920, fix binlog.binlog_killed
This is a followup to the fix of
Bug#51920 Innodb connections in row lock wait ignore KILL until lock wait
timeout
in that fix (rb://279) the behavior was changed to honor when a trx is
interrupted during lock wait, but the returned error code was still
"lock wait timeout" when it should be "interrupted".
This change fixes the non-deterministically failing test binlog.binlog_killed,
that failed like this:
binlog.binlog_killed 'stmt' [ fail ]
Test ended at 2010-05-12 11:39:08
CURRENT_TEST: binlog.binlog_killed

Approved by: Sunny Bains (rb://344)
------------------------------------------------------------
This merge is non-trivial since it has to introduce the DB_INTERRUPTED
error code.
Also revert vasil.dimov@oracle.com-20100408165555-9rpjh24o0sa9ad5y
which adjusted the binlog.binlog_killed test to the new (wrong) behavior
Also make InnoDB thinks that /*/ only starts a comment. (Bug #53644).
This fixes the bugs in the InnoDB Plugin.
ha_innodb.h: Use trx_query_string() instead of trx_query() when
available (MySQL 5.1.42 or later).
innobase_get_stmt(): New function, to retrieve the currently running
SQL statement.
struct trx_struct: Remove mysql_query_str. Use innobase_get_stmt() instead.
dict_strip_comments(): Add and observe the parameter sql_length. Treat
/*/ as the start of a comment.
dict_create_foreign_constraints(), row_table_add_foreign_constraints():
Add the parameter sql_length.
Also make InnoDB thinks that /*/ only starts a comment. (Bug #53644).
struct trx_struct: Add mysql_query_len.
ha_innodb.cc: Use trx_query_string() instead of trx_query() and
initialize trx->mysql_query_len.
INNOBASE_COPY_STMT(thd, trx): New macro, to initialize
trx->mysql_query_str and trx->mysql_query_len.
dict_strip_comments(): Add and observe the parameter sql_length. Treat
/*/ as the start of a comment.
dict_create_foreign_constraints(), row_table_add_foreign_constraints():
Add the parameter sql_length.

Bugfix for 53290, fast unique index creation fails on duplicate null values
Summary:
Bug in the fast index creation code incorrectly considers null
values to be duplicates during block merging. Innodb policy is that
multiple null values are allowed in a unique index. Null duplicates
were correctly ignored while sorting individual blocks and with slow
index creation.
Test Plan:
mtr, including new test, load dbs using deferred index creation

This is the 5.1 merge and extension of the fix.
The server was happily accepting paths in table name in all places a table
name is accepted (e.g. a SELECT). This allowed all users that have some
privilege over some database to read all tables in all databases in all
mysql server instances that the server file system has access to.
Fixed by :
1. making sure no path elements are allowed in quoted table name when
constructing the path (note that the path symbols are still valid in table names
when they're properly escaped by the server).
2. checking the #mysql50# prefixed names the same way they're checked for
path elements in mysql-5.0.
Iterative patch improvement. Previously committed patch
caused wrong result on Windows. The previous patch also
broke secure_file_priv for symlinks since not all file
paths which must be compared against this variable are
normalized using the same norm.
The server variable opt_secure_file_priv wasn't
normalized properly and caused the operations
LOAD DATA INFILE .. INTO TABLE ..
and
SELECT load_file(..)
to do different interpretations of the
--secure-file-priv option.
The patch moves code to the server initialization
routines so that the path always is normalized
once and only once.
It was also intended that setting the option
to an empty string should be equal to
lifting all previously set restrictions. This
is also fixed by this patch.
WHERE predicates containing references to empty tables in a
subquery were handled incorrectly by the optimizer when
executing EXPLAIN. As a result, the optimizer could try to
evaluate such predicates rather than just stop with
"Impossible WHERE noticed after reading const tables" as
it would do in a non-subquery case. This led to valgrind
errors and crashes.
Fixed the code checking the above condition so that subqueries
are not excluded and hence are handled in the same way as top
level SELECTs.
Extract part of innodb.innodb into innodb.innodb_misc1
This is needed in order to be able to more easily debug this test,
under valgrind, it is too huge.
The problem was in an incorrect debug assertion. The expression
used in the failing assertion states that when finding
references matching ORDER BY expressions, there can be only one
reference to a single table. But that does not make any sense,
all test cases for this bug are valid examples with multiple
identical WHERE expressions referencing the same table which
are also present in the ORDER BY list.
Fixed by removing the failing assertion. We also have to take
care of the 'found' counter so that we count multiple
references only once. We rely on this fact later in
eq_ref_table().
