In innodb_bug38231.test: replace the fragile sleep 0.2 that depends on timing
with a more robust condition which waits for the TRUNCATE and LOCK commands

are other sessions executing the same SQL commands, but there are none during
the execution of the mysql test.

Add the missing --reap statements in innodb_bug38231.test. Probably MySQL
enforced the presence of those recently and the test started failing like:

InnoDB logs error repeatedly when trying to load page into buffer pool

In buf_page_get_gen() if we are unable to read a page (because of
corruption or some other reason) we keep on retrying. This fills up
error log with millions of entries in no time and we'd eventually run

make (currently set to 100) and after that we abort with a message.

we had an assertion that would fail. Change that assertion and treat a value

This the fix for the first part of Bug #41609 from InnoDB Plugin to
the built-in InnoDB in MySQL 5.1. This allows InnoDB Hot Backup to
back up a database while the built-in InnoDB in MySQL 5.1 is creating
temporary tables. (This fix does not address the printouts about
missing .ibd files for temporary tables at InnoDB startup, which was
committed to branches/zip in r6252.)

rb://219 approved by Sunny Bains.

branches/zip: Distinguish temporary tables in MLOG_FILE_CREATE.
This addresses Mantis Issue #23 in InnoDB Hot Backup and some
of MySQL Bug #41609.

In MLOG_FILE_CREATE, we need to distinguish temporary tables, so that
InnoDB Hot Backup can work correctly.  It turns out that we can do this
easily, by using a bit of the previously unused parameter for page number.
(The page number parameter of MLOG_FILE_CREATE has been written as 0 
ever since MySQL 4.1, which introduced MLOG_FILE_CREATE.)

MLOG_FILE_FLAG_TEMP: A flag for indicating a temporary table in
the page number parameter of MLOG_FILE_ operations.

fil_op_write_log(): Add the parameter log_flags.

fil_op_log_parse_or_replay(): Add the parameter log_flags.
Do not replay MLOG_FILE_CREATE when MLOG_FILE_FLAG_TEMP is set in log_flags.
This only affects ibbackup --apply-log.  InnoDB itself never replays file
operations.

    This patch addresses this issue by extending the existing check in

after several selects on a large DB

During stress environment, Windows AIO may fail with error code
ERROR_OPERATION_ABORTED. InnoDB does not handle the error, rather
crashes. The cause of the error is unknown, but likely due to
faulty hardware or driver.

This patch introduces a new error code OS_FILE_OPERATION_ABORTED,
which maps to Windows ERROR_OPERATION_ABORTED (995). When the error
is detected during AIO, the InnoDB will issue a synchronous retry
(read/write).

This patch has been extensively tested by MySQL support.
