Hi, We have built a Trace Tool for the NPTL, called PTT.
This trace tool enables to trace: - the calls to and exits from NPTL routines - the internal behavior of the NPTL This tool is aimed to help: - developers of Multi-threaded applications - members of Linux Distribution Support Teams - NPTL maintainers This tool has now reached a good level of features and quality (though we know more work is required to make it complete, scalable, ...). We have built a patch for glibc 2.3.5 and packages for Debian and Fedora Core 3 and 4. First measures on 2xia32 show that the patch does not modify the behavior of the applications (OPTS runs perfectly) and that the performance impact is acceptable (between 2% and 16% depending on the application. 16% is reached with stress tests: VolanoMark/JRockit). The tool has been ported on PowerPC and ia64. This tool will be presented at the OLS at the end of July: http://www.linuxsymposium.org/2005/view_abstract.php?content_key=45 as part of a Bull project aimed to stabilize the NPTL. The next step is to make this tool available to all people using POSIX threads on Linux. >>>> Do you think it could be possible to provide this tool >>>> some day as an official Debian package ? Here are useful links to the tool: http://sourceforge.net/projects/nptltracetool http://nptltracetool.sourceforge.net/ http://nptl.bullopensource.org/ PTT has been built under my direction and with the help of an expert in POSIX Threads by 4 students of French Universities. It is delivered with documentation and tests.
