Abstract: Technologies for implementing customized behaviors for content items are provided. An example method can include receiving, from a user account registered with a content management system, a request to access a content item managed by the content management system for the user account, the content item having one or more behaviors configured for an attribute associated with the content item and/or the content item associated with the attribute; obtaining, from a representation of a remote state of content items associated with the user account, metadata defining the attribute associated with the content item; based on the metadata, determining the one or more behaviors configured for the attribute and/or the content item associated with the attribute; and applying the one or more behaviors to the content item.

Abstract: The present technology can move operating system folders into a sync folder of a cross platform content management system, and redirect the operating system to look for the OS folders in the sync folder. The present technology also provides an invariant checker to make sure that another application has not moved the OS folders after they have been placed in the sync folder, and provides solutions when the OS folders are moved out of the sync folder of the content management system. Additionally, when OS folders for multiple client devices are in the sync folder on the content management system, the present technology can provide a mechanism to make the content items in an OS folder on a first client device also sync into an OS folder on second client device.

Abstract: In some embodiments, an interface of a content management system manages synchronized content on storage systems. For example, the interface stores, on a metadata storage structure, records of metadata associated with blocks of data stored on a storage, the records including block identifiers that uniquely identify the blocks and timestamps associated with the blocks. The interface identifies a batch of storage operations associated with the blocks, including one or more delete operations. For each delete operation, the interface queries the metadata storage structure for a timestamp corresponding to a block of data associated with the delete operation, determines whether the delete operation creates a race condition between the delete operation and an add operation associated with the block of data, and rejects the delete operation when the delete operation creates the race condition or the timestamp corresponding to the block of data is newer than a predetermined period of time.

Abstract: The disclosed technology relates to a system configured to compute a difference between a remote tree data structure representing a server state for content items associated with an account on a content management system and a sync tree data structure representing a known synchronization state between the content management system and the computing system. The system is configured to generate, based on the difference, a set of operations that when performed on the computing system update the content items stored on the client device to converge a file system state on the computing system and the server state.

Abstract: A synchronization protocol for multi-premises hosting of digital content items. In an embodiment, a method includes receiving a first commit request including a first set of one or more identifiers of one or more first content item blocks. The one or more first content item blocks make up a content item stored at a computing device. Further, the method includes, based at least in part on the first commit request, determining a second set of one or more identifiers that includes one or more identifiers of the first set of one or more identifiers not yet stored at a content item block server. The method also includes sending, to the computing device, the second set of one or more identifiers, and receiving a second commit request including the first set of one or more identifiers of the one or more first content item blocks, and an identifier of the content item block server. In this embodiment, the method then includes determining that no content item block from the one or more first content item blocks is missing at the content item block server, and committing the content item to the content item block server.

Abstract: An interface of a content management system manages storage and access of content on the system. For example, after receiving, from a client, a request to download a content item, the interface determines whether the request includes a valid token. If so, the interface sends a content item request to a storage service, retrieves the content item, and sends the content item to the client. Otherwise, the interface sends an authorization request to an authorization service, an authentication request to an authentication service, and a content item request to the storage service. Based on the requests, the interface determines whether the content item is available in storage and whether the client is authorized to access the content item. When the content item is available in storage and the client is authorized to access the content item, the interface retrieves the content item and sends the content item to the client.

Abstract: The disclosed technology relates to a system configured to identify at least one difference between a sync tree and at least one of a remote tree and a local tree. The sync tree represents a known synced state between a server state and a file system state, the remote tree represents the server state, and the local tree represents the file system state. The system may further generate, based on the at least one difference, a set of operations configured to converge the server state and the file system state and manage the execution of the set of operations.

Abstract: A content item block replication protocol for multi-premises hosting of digital content items. In one embodiment, for example, a method comprises: receiving, from a server, a server journal entry identifying one or more content item blocks of a content item represented by the server journal entry; storing a replication log entry corresponding to the server journal entry in a replication log, the replication log entry identifying the one or more content item blocks of the content item represented by the server journal entry and identifying a block server; and either offering to send the one or more content item blocks identified in the replication log entry to the block server identified in the replication log entry, or downloading the one or more content item blocks identified in the replication log entry from the block server identified in the replication log entry.
