Number.Control by interlockedexchange whether detection thread exits.
Step s102, creates one and detects mesh specified by application program described in described service end in described detection thread
When document under record changes, the document information needing synchronous change is transmitted to the connection object of described synchronizing thread.
Step s103, described detection thread obtains the literary composition under catalogue specified by application program described in described client respectively
The database information of the document under catalogue specified by corresponding described application program in the database information of shelves and described server.
Specifically, described detection thread obtains service end database information by the open api that service end provides, described
Detect the data base api that encapsulates by local client of thread and obtain local client data storehouse information.
Wherein, the file catalogue of the document under catalogue specified by described application program is the file catalogue wanting to detect, this
File catalogue can set according to demand.
Wherein in the present embodiment, described database information includes: docid: file unique mark, generates one by service end
The character string of individual unique 64 characters, that is, described file unique mark generated by service end, that is, in service end, All Files is all
Have a different docid；Otag: file change identifies, and is generated the character string of unique 64 characters by service end,
If file or file change, the change changing this file or folder identifies and updates parent directory and ancestors' mesh
The change mark of record.I.e. described file change mark service end generates, and described service end has file or folder change, then can
Update the otag of this document or file and ancestor directories.
Step s104, described detection thread extracts in database information in described client and described service end in advance respectively
The document unique mark setting for described document and document change mark.
Step s105, described detection thread passes through uniquely to mark the document extracting in database information from described client
The document unique mark extracted in knowledge and database information from described service end compares, and obtains document in described server
Increase newly and delete.
Specifically, in the present embodiment, in the described server of described acquisition, the detailed process that is newly-increased and deleting of document is:
If not having to carry in database information in described service end in the document unique mark extracted in database information in described client
