Type: Effort Status: suspended 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

Unfortunately, this effort is currently suspended due to other topics. It hopefully gets resumed after finishing Packaging.

Tasks

The below list of efforts and tasks shows what needs to be done.
