Publishing handles how content gets published from an author instance to a public instance. Publishing is installed by the Publishing module and extended by the Publishing Transactional module (in DX Core).
Publishing is a refactored version of the former activation. The original Activation module has been broken into multiple submodules, see the module structure. The driving decision was to have a set of maintainable and extensible components. Another reason was to remove deprecated code. The core concepts remain the same. The transport layer is still using the HTTP protocol, but you can now easily plug in any type of transport layer.
The publishing implementation also allows you to define and use custom publishing operations with which you can publish content to something that is not a Magnolia public instance, for example to a custom API or a Content Delivery Network.
PublishingCommand collects the content that needs to be
(un)published. This content is then sent to an implementation of
Sender, a component responsible for content packaging.

PublicationFilter receives a sender’s request. The request is then
sent to the
Dispatcher which decides what to do with the request
depending on the request headers. The
Dispatcher extracts the data
from the request and creates a
ReceiveOperation responsible for
creating/updating/deleting the content.
All siblings of a published node appear in the same order as on the author instance at the time of approving publication.
If you are publishing nodes with hundreds of child nodes, you may need to disable ordering to significantly speed up the process.
To do so, set
|This default behavior does not take into account the order at any other point in time (such as the time of creating the published version).|
Each publishing request executes a lock for either a path or node where content is to be published.
Path-based locking has been introduced as the default way of locking with version 1.2.6 of the Publishing module. Node-based locking is available for compatibility reasons. See the
In case two users publish to the same (sub)tree, the locking mechanism will wait with a predefined amount of time and will try to obtain a lock for the operation. If the operation receives the lock, it can proceed with content (un)publishing. If not, publishing is considered unsuccessful and the respective status code is returned to the sender.
Content publishing and content synchronization
Always wait with content publishing actions until all content synchronization tasks have been finished.
If you attempt to publish a page while the Synchronization module is mid-sync and has not yet synchronized the page’s parent, the publishing process will fail.
Magnolia supports two methods of publishing content:
Non-recursive, which publishes only the selected node and its properties.
Recursive, which publishes the selected node, its properties and its children.
Transactional publishing provides a way to publish content-managed transactions. Content will be:
commitedif all receivers respond with success status.
rollbackedif at least one of the receivers respond with error status.
The transactional publishing receiver uses
mgnlSystem workspace to
store the backups of the published content. If content is to be
commited, the backup is removed. If content is to be rollbacked, the
backup is restored to the workspace it belongs to.
The Publishing module makes all workspaces publishable by default.
Magnolia ships with publishing approval and rejection workflows. By default, it is only enabled in the Pages app.
Disabling the workflow in the Pages app may be appropriate for a simple site workforce where there are no separate editor and publisher roles.
To disable the publishing workflow for the Pages app:
Remove the following decoration:

/modules/publishing-core/commands/default/publishnode with the following values:
Removing a decoration?
The only way to remove an existing decoration is to either override it with another decoration or remove the whole module with the original decoration.
