Author: Laurynas Biveinis
Revision Date: 2014-01-21 10:12:02 UTC

Add support for storage engines with online OPTIMIZE, implementing
https://blueprints.launchpad.net/percona-server/+spec/allow-writes-during-table-optimization.

The implementation is based on a combination of
https://github.com/Tokutek/mysql56/commit/1a321b6ae70f76da3dc76c944014baab2b7ce1ae
and
https://github.com/Tokutek/mysql56/commit/a701cea6de67c713d418a319a6a8486da8e07ff2

It adds a new handler table flag HA_CAN_WRITE_DURING_OPTIMIZE. While
executing OPTIMIZE, after opening the tables, the presence of this
flag is checked and the MDL lock is downgraded from
MDL_SHARED_NO_READ_WRITE to MDL_SHARED_WRITE, and the closing of any
open instances of this table for other connections is skipped.

Adjust handler::ha_optimize() to assert that HA_ADMIN_TRY_ALTER return
value is incompatible with HA_CAN_WRITE_DURING_OPTIMIZE.

Adjust MDL_ticker::downgrade_lock() to allow downgrades from
MDL_SHARED_NO_READ_WRITE.

Revision Date: 2013-02-12 06:39:39 UTC

Fix bug 1122462 (InnoDB: Failing assertion: bpage->in_flush_list in
file buf0lru.c line 605).

The issue is that, even after fixing bug 934377 and friends, there is
not enough protection for the "prev" pointer in the
buf_flush_or_remove_pages() loop to start pointing to a flushed page
or become dangling due to a compressed page flush list relocation.

The fix is two part. First is acquiring the compressed page flush
mutex in buf_flush_dirty_pages() (and releasing it in
buf_flush_yield()). This ensures that the prev pointer always points
to a valid page.

The second part is to fix that, while prev cannot become dangling
anymore, it still may get removed from the flush list when the flush
list mutex is released. This is handled by replacing the assertions
at the top of the buf_flush_or_remove_pages() loop with a block state
check.

Remove some comments that do not apply for XtraDB.

Experimental helgrind support

Revision Date: 2012-05-11 10:31:52 UTC

Annotate the MEMORY engine block allocator for Valgrind.

- Add 10-byte-long redzones before and after each block when compiled
  with Valgrind support. Mark them as inaccessible on block
  allocation.
- Mark block contents as undefined on block deallocation and
  allocation that recycles blocks from the free list.
- Bump block offset link from 1 << 22 to 1 << 31 for fixed-length
  blocks in order to make errorneous accesses crash sooner when
  fixed-length blocks are treated as variable-length.
