[Valgrind-developers] [ANNOUNCEMENT] DRD, a Thread Error Detector

[Bart V. A. <bar...@gm...>]

DRD is a pure happens-before data race detector implemented as a
Valgrind tool. The happens-before algorithm which DRD is based upon
guarantees not to report any false positives.

An experimental version of the DRD tool, called exp-drd, was already
included with the Valgrind releases 3.3.0 and 3.3.1. This tool has
been renamed to drd and will be included with the 3.4.0 release of
Valgrind. Since release 3.3.1 the DRD tool became significantly
faster, uses less memory, supports detection of lock contention, and
supports now also POSIX reader-writer locks, barriers and the Qt4
library.

A release candidate of DRD can be found on the Valgrind trunk, and can
be downloaded, compiled and installed as follows:

svn co svn://svn.valgrind.org/valgrind/trunk valgrind
cd valgrind && ./autogen.sh && ./configure --prefix=$HOME/valgrind-3.4.0.SVN
make -s && make -C docs -s html-docs && make -s install
konqueror ~/valgrind-3.4.0.SVN/share/doc/valgrind/html/drd-manual.html &

Any feedback about the tool or its documentation is welcome. Please
keep in mind that the feature freeze date for the Valgrind 3.4.0
release is on Friday August 1, 2008.

Bart.
