Selective synchronization of content items in a content management system
A system can selectively synchronize content based on synchronization settings. In some examples, a client stores a local tree representing a local set of content items associated with an account on a content management system, the local tree including respective local nodes corresponding to the local set of content items. The client stores a remote tree representing a remote set of content items associated with the account, the remote set being stored at the content management system and including respective remote nodes corresponding to the remote set of content items. The client receives a synchronization setting disabling local storage of the content item. In response, the client deletes a local copy of the content item, removes a corresponding local node from the local tree, and adds, to a remote node on the remote tree, an attribute indicating that local storage of the content item has been disabled.
1 . A method comprising:
storing, on a client device, a local tree data structure representing content items in a file system on the client device and a remote tree data structure representing a remote set of content items stored at a content management system;
detecting a remote change to a content item of the remote set of content items by receiving an update to the remote tree data structure from the content management system;
in response to the detection, determining an attribute in the remote tree data structure that indicates a synchronization setting disabling local storage of the content item is set, wherein the attribute is stored in association with a respective node in the remote tree data structure, whereby the content item is excluded from being stored on the client device and excluded from being represented via the local tree data structure as a result of a future synchronization while the attribute remains in the remote tree data structure and in association with the respective node corresponding to the content item on the remote tree data structure; and
based on the attribute being stored at the remote tree data structure, denying a corresponding update to the local tree data structure.
2 . The method of claim 1 , wherein receiving the synchronization setting comprises:
deleting a local copy of the content item from the client device.
3 . The method of claim 1 , wherein receiving the synchronization setting comprises receiving, via a graphical user interface on the client device, user input identifying the synchronization setting.
4 . The method of claim 1 , further comprising presenting, via a graphical user interface, the content items in the file system on the client device and one or more graphical control elements for selecting respective synchronization settings for the content items in the file system on the client device.
5 . The method of claim 1 , further comprising:
in response to the remote change, updating a representation of the content item on the remote tree data structure to reflect the remote change, the representation of the content item on the remote tree data structure being based on a server state associated with the content item.
6 . The method of claim 1 , further comprising:
detecting one or more changes to at least one of the remote tree data structure or the local tree data structure; and
based on the one or more changes, synchronizing the remote tree data structure and the local tree data structure.
7 . The method of claim 6 , wherein synchronizing the remote tree data structure and the local tree data structure comprises:
identifying a representation of the content item on the remote tree data structure;
determining that a hidden attribute is associated with representation of the content item in the remote tree data structure; and
based on the hidden attribute, continue excluding the representation of the content item from the local tree data structure.
8 . The method of claim 7 , wherein the one or more changes represent a move operation at the content management system, the move operation moving a remote copy of the content item from a first path to a second path, and wherein the one or more changes comprise moving the representation of the content item associated with the content item to a different location within the remote tree data structure, the different location corresponding to the second path.
9 . The method of claim 8 , wherein moving the representation of the content item to the different location comprises storing the representation of the content item at the different location in the remote tree data structure and retaining the hidden attribute associated with the representation of the content item.
10 . The method of claim 7 , further comprising:
detecting an add operation at the client device, the add operation adding a second content item on the client device, the second content item being stored at a path associated with the representation of the content item and a remote copy of the content item;
determining that synchronization of the second content item at the client device would create a conflict with the remote copy of the content item based on the path comprising a same path for both the second content item and the remote copy of the content item;
in response to determining the conflict, modifying the path of the second content item on the client device to yield a second path; and
storing the second content item on the client device at the second path.
11 . The method of claim 10 , further comprising:
adding a representation of the second content item to the local tree data structure, the representation of the second content item representing the second content item and associating the second content item with the second path; and
in response to adding the representation of the second content item to the local tree data structure, synchronizing the local tree data structure and the remote tree data structure, wherein synchronizing the local tree data structure and the remote tree data structure comprises adding a representation of the second content item to the remote tree data structure corresponding to a remote copy of the second content item.
12 . The method of claim 11 , wherein the representation of the second content item on the remote tree data structure associates the remote copy of the second content item with the second path.
13 . A non-transitory computer readable medium comprising instructions, the instructions, when executed by a client device, cause the client device to:
store a local tree data structure representing content items in a file system on the client device and a remote tree data structure representing a remote set of content items stored at a content management system;
detect a remote change to a content item of the remote set of content items by receiving an update to the remote tree data structure from the content management system;
in response to the detection, determine an attribute in the remote tree data structure that indicates a synchronization setting disabling local storage of the content item is set, wherein the attribute is stored in association with a respective node in the remote tree data structure, whereby the content item is excluded from being stored on the client device and excluded from being represented via the local tree data structure as a result of a future synchronization while the attribute remains in the remote tree data structure and in association with the respective node corresponding to the content item on the remote tree data structure; and
based on the attribute being stored at the remote tree data structure, deny a corresponding update to the local tree data structure.
14 . The non-transitory computer readable medium of claim 13 , wherein receiving the synchronization setting comprises:
deleting a local copy of the content item from the client device.
15 . The non-transitory computer readable medium of claim 13 , wherein receiving the synchronization setting comprises receiving, via a graphical user interface on the client device, user input identifying the synchronization setting.
16 . The non-transitory computer readable medium of claim 13 , storing instructions which, when executed by the client device, cause the client device to:
in response to the remote change, update a representation of the content item on the remote tree data structure to reflect the remote change, the representation of the content item on the remote tree data structure being based on a server state associated with the content item.
17 . The non-transitory computer readable medium of claim 13 , storing instructions which, when executed by the client device, cause the client device to:
