Shared Condition

While not the primary focus of the library, Door also offer implementations of read-preferring and write-preferring shared conditions (readers-writer conditions).

The usual acquire/release/wait/notify interface as modelled by door.primitives.Waitable is not sufficient to describe the functionalities of shared conditions. Therefore, for door.primitives.SWaitable, we expand the interface as follows:

• acquire-read

• release-read

• wait-read

• wait-for-read

• notify-read

• notify-all-read

• acquire-write

• release-write

• wait-write

• wait-for-write

• notify-write

• notify-all-write

We offer implementations for both synchronous and asynchronous programming. These classes of shared conditions are available, for different use cases:

Read-preferring:

• door.threading2.RSCondition for multithreading.

• door.multiprocessing2.RSCondition for multiprocessing.

• door.asyncio2.RSCondition for asynchronous programming.

Write-preferring:

• door.threading2.WSCondition for multithreading.

• door.multiprocessing2.WSCondition for multiprocessing.

• door.asyncio2.WSCondition for asynchronous programming.
