Uno/Spec/Threading-Model

Type: Specification State: draft

Feature

The Runtime provides dedicated support for implementing and handling

• thread-safe,
• thread-unsafe, and
• thread-affine

code. The threading type of any code can be specified appropriately. The thread-unsafe type is the default type for any implementation.

Rationale

The Analysis/Multi-Threading shows OOo deficiencies wrt to multi-threading and thread-safeness. The Architecture/Goals for OOo Threading-Model&-Architecture identify three thread related types of code (thread-unsafe, thread-safe and thread-affine).

API

Two thread related purposes:

• ":unsafe" - for thread-unsafe code.
• ":affine" - for thread-affine code.
