Abstract: In in-memory workspace management, a request is received from a user to open a document. It is determined whether the document is opened. Upon determining that the document is already opened, an existing workspace instance corresponding to the opened document is shared with the user. A mapping between the workspace request identifier and a workspace identifier is maintained in a workspace map. A reference count mapped to the workspace identifier is incremented since the existing workspace instance is shared with the user. It is determined whether the document is edited. The shared workspace instance is discontinued from sharing and is forked to create a new workspace instance for editing. The mapping between workspace request identifier and workspace identifier is removed from the workspace map. The reference count map is updated to decrement the reference count corresponding to the workspace identifier.

Abstract translation: 在内存中工作空间管理中，从用户接收到打开文档的请求。 确定文档是否打开。 一旦确定文档已经被打开，与打开的文档相对应的现有工作空间实例将与用户共享。 工作空间请求标识符和工作空间标识符之间的映射保留在工作区映射中。 由于现有的工作区实例与用户共享，因此映射到工作区标识符的引用计数将递增。 确定文档是否被编辑。 共享工作区实例从共享中断，并被分支以创建一个新的工作区实例进行编辑。 从工作区映射中删除工作区请求标识符和工作区标识符之间的映射。 参考计数图被更新以减少与工作空间标识符相对应的参考计数。
