Post-merge fixes: Remove the MYSQL_VERSION_ID checks, because they only
apply to the InnoDB Plugin. Fix potential race condition accessing
trx->op_info and trx->detailed_error.

message:
Make the InnoDB FOREIGN KEY parser understand multi-statements. (Bug #48024)
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.
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
mysqltest: At line 208: query 'reap' failed with wrong errno 1205: 'Lock wait timeout exceeded; try restarting transaction', instead of 0...
Approved by: Sunny Bains (rb://344)
in the code but they have nothing to do with the kernel mutex split code.
Some subsequent commits use the new functions. This patch has been tested
with: ./mtr --suite=innodb with UNIV_DEBUG and UNIV_SYNC_DEBUG enabled.
All tests were successful.

Merge a patch from Facebook to fix Bug #53290
commit e759bc64eb5c5eed4f75677ad67246797d486460
Author: Ryan Mack
Date: 3 days ago
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

Remove UNIV_BTR_AVOID_COPY. It was broken because btr_attach_half_pages()
would get the block, new_block in the wrong order.
Fixing that would have complicated the function even further
for this marginal case.

lock monitor thread, it may have locks that are granted to waited to
waiting transactions. These waiting transactions will need to be woken
up but their trx->lock_wait_timeout flag will be FALSE causing the old
code to break. What we need is a flag that covers the entire lock
release process not individual transactions. The fix is to move the
flag out of trx_t and into srv_sys_t.
was skipped because another flush batch was active. This is to
ensure that the when we return success then it is guaranteed that
all pages up to the lsn_limit have been flushed to the disk.
