OOo Threading Architecture

The OOo Threading Architecture leverages Unos Threading Model to only implement thread safe code where necessary, to achieve a Basic Threading Architecture. All components, libraries and applications default to be thread unsafe, with only a few well motivated exceptions, which are specified as thread safe respectively as thread affine.

All office code is specified to be Thread Transparent.

Thread Safe

The following modules are specified to be thread safe:

• ucb
• ucbhelper
• configmgr
• ?desktop?/pkgmagr

Thread Affine

The following modules are specified to be thread affine:

• svtools/DDE
• dtrans/?clipboard?
• dtrans/?Drag&Drop?

Threads

• vos timer thread
• dtrans threads (clipboard and D&D)
• ucbhelper: background download thread
• ICE thread
• configuration flash thread
• Win32: affinity thread
• office acceptor thread - second process thread
• uno acceptor thread
• io - pump thread
• package manager deployment gui thread
• UNO job threads
