- This patch does the following: git revert --no-commit673243c893git revert --no-commit6c669b9586git revert --no-commitbacaf2d4f4git checkout HEAD mysql-test git revert --no-commit1fd7d3a9adAbove command reverts MDEV-29277, MDEV-25581, MDEV-29342. When binlog is enabled, trasaction takes a lot of time to do sync operation on innodb fts table. This leads to block of other transaction commit. To avoid this failure, remove the fulltext sync operation during transaction commit. So reverted MDEV-25581 related patches. We filed MDEV-31105 to avoid the memory consumption problem during fulltext sync operation.
