Embodiment Construction

[0030] Abbreviations and key terms involved in the present invention are defined as follows:

[0031] Co-editing node: A user who participates in a co-editing session as a co-editing session.

[0032] Main editing node: the first user who creates the topic session, it is the coordinator of this session, and is mainly responsible for the arbitration of co-editing node lock applications in this session and the management of the session.

[0033] Reference lock: It is the previous lock in the locked position when applying for a lock, and it is used as a reference point for locking position conversion.

[0034] Relative position: refers to the distance from the end position of the reference lock to the starting position to be locked.

[0035] Lock conflict: There are situations where the locking ranges of two mutexes overlap, overlap, or include. The structure of the collaborative editing system involved in the present invention:

[0036] The system structure of the locking met...

Abstract

The invention discloses a lock adding method to a data conflict module in a cooperative editing, locking within editing position scope of each cooperator must be recognized by the chief editing node of the belonged group, each cooperator only has one lock, and can carry through various editing operations randomly within the locking range; each node is stored with a locking table of group member, when the local locking operation is happening, firstly scanning the local locking table to check whether conflict exists, if yes, PRI judging can be passed through, and then judging result of adding lock can be sent to the chief editing node and arbitrated by the chief editing node; the invention brings forward a humanized lock adding method, so that not only the efficiency of cooperative editing can be improved, but also the conflict can be flexibly processed; the lock adding method has easy realization, solves defects of original technical scheme and has good expansibility; the invention also provides an elastic data conflict solution, and is able to satisfy cooperative requirements of multi-people distributed type cooperative editing.

Description

technical field [0001] The invention relates to a method for locking in collaborative editing, in particular to a method for locking data conflict modules in collaborative editing. Background technique [0002] With the emergence of large-scale editing needs and the continuous development of network technology, distributed collaborative editing systems emerged and began to develop rapidly. The collaborative editing system structure is divided into the main editing node and the co-editing node. The main editing node creates a session, and the co-editing node participates in the session. During the session, the most important task is to discover and resolve conflicts that may exist when multiple people are editing at the same time while ensuring efficiency. Therefore, locking the editing object is introduced. The locking mechanism mainly includes the following types: traditional locking method, tickle lock, floor control, reversible execution (Undo / Redo) and operation convers...
