Rename type_bit_innodb.diff to bug32625.diff since an equivalent patch has
been submitted to MySQL as Bug#32625 Make test type_bit_innodb more robust.

type_bit_innodb.diff: Ignore the reported duplicate value.  The reported
value depends on the internal workings of the merge sort in
fast index creation.  In the built-in InnoDB of MySQL 5.1, the records
are copied to a new temporary table in the order they were selected from
the original table.

information_schema.diff: Account for the INFORMATION_SCHEMA tables that
were added in the InnoDB plugin.

innodb_file_per_table.diff: In the InnoDB plugin, innodb_file_per_table
is a settable global variable.

page_zip_fail_func(): Display the timestamp.

page_zip_validate_low(): Display information about ignored min_rec_flag

page_zip_validate_low(): Renamed from page_zip_validate(), with an
additional parameter: ibool sloppy.  Ignore REC_INFO_MIN_REC_FLAG when
sloppy == TRUE.

page_zip_validate(): Wrapper for page_zip_validate_low().  Pass

  branches/5.1: This bug has always existed but was masked by other errors. The
  fix for bug# 38839 triggered this bug. When the offset and increment are > 1
  we need to calculate the next value taking into consideration the two
  variables. Previously we simply assumed they were 1 particularly offset was
  never used. MySQL does its own calculation and that's probably why it seemed
  to work in the past. We would return what we thought was the correct next
  value and then MySQL would recalculate the actual value from that and return
  it to the caller (e.g., handler::write_row()). Several new tests have been
  added that try and catch some edge cases. The tests exposed a wrap around
  error in MySQL next value calculation which was filed as bug#39828. The tests
  will need to be updated once MySQL fix that bug.
  
  One good side effect of this fix is that dict_table_t size has been
  reduced by 8 bytes because we have moved the autoinc_increment field to
  the row_prebuilt_t structure. See review-board for a detailed discussion.

fields that are related to the records stored in the page.

page_zip_copy() is a fall-back method in certain B-tree operations
(tree compression, splitting or merging nodes).  The contents of a
page may fit in the compressed page frame when it has been modified in
a certain sequence, but not when the page is recompressed.  Sometimes,
copying all or part of the records to an empty page could fail because
of compression overflow.  In such cases, we copy the compressed and
uncompressed pages bit for bit and delete any unwanted records from
the copy.  (Deletion is guaranteed to succeed.)  The method
page_zip_copy() is invoked very rarely.

In one case, page_zip_copy() was called in btr_lift_page_up() to move
the records to the root page of the B-tree.  Because page_zip_copy()
copied all B-tree page header fields, it overwrote the file segment
header fields PAGE_BTR_SEG_LEAF and PAGE_BTR_SEG_TOP.  This is the
probable cause of the corruption that was reported as Mantis issue #63
and others.

add some ut_a() assertions to track down file space header corruption
that is the probable cause of Mantis issue #63.

Return earlier when this function is called on an index that
is being created.  Luckily, mtr_start() does not allocate any
resources.  Thus, there was no memory leak.
