POSIX Timers Test Pass Data Available

Test pass data is now available from running the latest POSIX Timers conformance/interfaces suite against two POSIX Timers implementations: George Anzinger's High Res Timers and Jim Houston's Alternate Timers:

Test pass data is there more to show how data will be output than for the data itself (timers/conformance/interfaces is only a small piece of the eventual full POSIX Timers test suite, which should have functional, stress, and performance tests also).

Project Kickoff

This project began on October 11, 2002. After some initial development and definition, the project was announced on the linux-kernel mailing list on November 3rd.

Developers are now actively writing conformance tests in Signals, Message Queues, Timers, and will be starting soon in Semaphores. Discussions are underway about further defining the purpose and structure of functional, stress, and conformance/behavior test areas.... read more
