Effort/Revise OOo Multi-Threading

Type: Effort Status: in progress Owner: Kay Ramme

The OOo Threading Effort attempts to clean-up OOos threading-model (how to use threads) and to implement a specified threading-architecture (where and when to use threads), providing an overview and documentation of the threads used in OOo. Further improvement is planned to be implemented in another effort, eventually leading to an advanced threading-architecture.

Problem

More or less frequently people complain about OOo with respect to multi-threading. Either because it is complicated to implement a service, or that there is only few documentation, or that the Uno API is not thread safe, or that it does not scale etc.

Approach

Analyse the current state. Find and propose a solution, ideally based on Uno, and implement it.

Time Frame

Current understanding of the topic lets us think, that the changes of OOo on behalf of the threading clean up effort are going to be integrated into some of the next updates and will probably mostly be finished until end 2006.
