It is a bug in unused code. If we don't calculate the hash value when
calculating the mutex number then two pages which map to same hash
value can get two different mutex numbers.

dictionary when renaming or dropping tables. It could have caused
deadlocks after acquiring latches on insert buffer bitmap pages.
This and r3544 should fix Issue #135.
Furthermore, the update-in-place-in-select does not account for
compression failure. That was not a problem yet, since the InnoDB SQL
interpreter has so far assumed ROW_FORMAT=REDUNDANT.

records in the insert buffer B-tree are never updated. This could cure
Issue #135.
btr_cur_optimistic_insert(): Do not update the insert buffer bitmap
when inserting to the insert buffer tree.
btr_cur_optimistic_delete(): Do not update the insert buffer bitmap
when deleting from the insert buffer tree. This could be the cause
of the assertion failure that was reported in Issue #135.
btr_cur_update_alloc_zip(): Assert that the index is not the insert
buffer. The insert buffer will never be stored in compressed format.
btr_cur_update_in_place(), btr_cur_optimistic_update(),
btr_cur_pessimistic_update(): Assert that these functions are never
invoked on the insert buffer tree. The insert buffer only supports
the insertion and deletion of records.
Originally, there were provisions in InnoDB for multiple insert buffer
B-trees, apparently one for each tablespace.
When Heikki implemented innodb_file_per_table (multiple InnoDB
tablespaces) in MySQL 4.1, he made the insert buffer live only in the
system tablespace (space 0) but left the provisions in the code.
When Osku Salerma implemented delete buffering, he also cleaned up the
insert buffer subsystem so that only one insert buffer B-tree exists.
This patch applies the clean-up to the InnoDB Plugin.
Having a separate patch of the insert buffer clean-up should help us
better compare the essential changes of the InnoDB Plugin and InnoDB+
and to track down bugs that are specific to InnoDB+.

Make the variables rw_latch and buf_mode local in the for loop.
Initialize them at the beginning of each for loop round to reduce
register spilling on register-starved platforms such as the x86. Move
the assignment of rw_latch and buf_mode from the end of the loop to
the beginning of the loop. These parameters will only be needed in
the buf_page_get_gen() call at the start of the loop.
Remove the second (redundant) call to ibuf_should_try().
ibuf_should_try(): Now that the successful calls to this function will
be halved, halve the magic constant that ibuf_flush_count will be

All three srv_buf_pool related variables are defined as ulong, which is

system_info.dwPageSize appears to be 32-bit only. Casting to 64-bit

The config param innodb_thread_concurrency is dynamically set and is
read when a thread enters/exits innodb. If the value is changed between
the enter and exit time the behaviour becomes erratic.
The fix is not to use srv_thread_concurrency when exiting, instead use
the flag trx->declared_to_be_inside_innodb.

Revert our temporary fix for Bug#40360 Binlog related errors with binlog off
This bug was fixed in MySQL code.
Our fix went into r2944 and r2947, but this patch does not entirely revert
those revisions because we want to leave the test case that was introduced
and also r2944 itself reverted r2935 and r2936. So if we completely revert
r2944 and r2947 then we would loose the test and will restore r2935 and
r2936.
This resolves Issue#108 We should remove ib_bin_log_is_engaged() once mysql
add an equivallent, see Bug#40360
Fix Mantis issue#103 mysql_addons.c depends on THD internals - please remove it
Use MySQL's thd_get_thread_id() instead of our own ib_thd_get_thread_id()
