Principles

Principles of the threading-architecture are

• all components, libraries and applications default to be thread-unsafe, with only a few well motivated exceptions (being thread-safe or thread-affine),
• all office APIs are specified to be thread-transparent.

Exceptions

Thread-Safe

The following modules are specified to be thread-safe:

• UCB (Universal Content Broker) Component - ucb/ucb
• UCB Helper Library - ucb/ucbhelper
• Config Manager Components - util/configmgr
• Package Manager - framework/desktop/source/pkgchk
• The office connection acceptor (server) component in the desktop project.

Thread-Affine

The following modules are specified to be thread-affine:

• DDE (Dynamic Data Exchange) - util/source/svdde/svtools
• Windows Clipboard Component - gsl/dtrans/source/win32/clipbe
• Windows Drag&Drop Component - gsl/dtrans/source/win32/dnd
• Windows Shell Execute Component - gsl/shell/source/win32
