Welcome to the Tsan Project!

The goal of this Project is to explore and incubate a Thread SANitizing (TSAN) feature that could be integrated into the HotSpot JVM and the JVM Tool Interface (JVM TI).  This includes working, evaluating, and incubating a Thread Sanitizer implementation for Java.


The rest of this page will provide basic information for downloading, building, and testing Java TSAN.


Note: Java TSAN is not working yet and will not be able to provide any data race information yet. The information below is really how to clone/test for developers and testers:


Cloning:

hg clone --branch dev http://hg.openjdk.java.net/tsan/dev jdk-tsan


Installing:

TODO: since TSAN is not even integrated yet, the JDK you just branched is the mainline.


Testing:

Currently, the tests for TSAN are here:


make run-test  TEST="jtreg:test/hotspot/jtreg/tsan"


The tests are currently passing if TSAN is not enabled; once TSAN starts coming online, the tests will flip their assertions/expectations.
