/**
*
* Publishing and Managing State
* ======
*
* After applying changes, the Editor queues a worker to publish mail, feed,
* and notifications, and to perform other background work like updating search
* indexes. This allows it to do this work without impacting performance for
* users.
*
* When work is moved to the daemons, the Editor state is serialized by
* @{method:getWorkerState}, then reloaded in a daemon process by
* @{method:loadWorkerState}. **This is fragile.**
*
* State is not persisted into the daemons by default, because we can not send
* arbitrary objects into the queue. This means the default behavior of any
* state properties is to reset to their defaults without warning prior to
* publishing.
*
* The easiest way to avoid this is to keep Editors stateless: the overwhelming
* majority of Editors can be written statelessly. If you need to maintain
* state, you can either:
*
* - not require state to exist during publishing; or
* - pass state to the daemons by implementing @{method:getCustomWorkerState}
* and @{method:loadCustomWorkerState}.
*
* This architecture isn't ideal, and we may eventually split this class into
* "Editor" and "Publisher" parts to make it more robust. See T6367 for some
* discussion and context.
*
* @task mail Sending Mail
* @task feed Publishing Feed Stories
* @task search Search Index
* @task files Integration with Files

/**
* Determine if the editor should hold a read lock on the object while
* applying a transaction.
*
* If the editor does not hold a lock, two editors may read an object at the
* same time, then apply their changes without any synchronization. For most
* transactions, this does not matter much. However, it is important for some
* transactions. For example, if an object has a transaction count on it, both
* editors may read the object with `count = 23`, then independently update it
* and save the object with `count = 24` twice. This will produce the wrong
* state: the object really has 25 transactions, but the count is only 24.
*
* Generally, transactions fall into one of four buckets:
*
* - Append operations: Actions like adding a comment to an object purely
* add information to its state, and do not depend on the current object
* state in any way. These transactions never need to hold locks.
* - Overwrite operations: Actions like changing the title or description
* of an object replace the current value with a new value, so the end
* state is consistent without a lock. We currently do not lock these
* transactions, although we may in the future.
* - Edge operations: Edge and subscription operations have internal
* synchronization which limits the damage race conditions can cause.
* We do not currently lock these transactions, although we may in the
* future.
* - Update operations: Actions like incrementing a count on an object.
* These operations generally should use locks, unless it is not
* important that the state remain consistent in the presence of races.
*
* @param PhabricatorLiskDAO Object being updated.
* @param PhabricatorApplicationTransaction Transaction being applied.
* @return bool True to synchronize the edit with a lock.
