Description of the change
Fix bug 1193332 ([Warning] InnoDB: changed page bitmap file
'./ib_modified_
at the end.)
The problem is bitmap writer thread working in parallel with bitmap
reader that processes an INFORMATION_
query, causing the latter to see partial data in the middle of the
write. The fix is, if the log tracker is running, to limit any
maximum LSN value for a query with an actual tracked LSN value.
Add a testcase to percona_
