SVNChecker is a framework for Subversion pre-commit hooks in order to implement checks of the to-be-committed files before they are committed. For example, you can check for the code style or unit tests. The output of the checks can be send by mail, written to a file, or simply printed to the console.
Perl::Critic is an extensible framework for creating and applying coding standards to Perl source code. Essentially, it is a static source code analysis engine. It is distributed with a number of Perl::Critic::Policy modules that attempt to enforce various coding guidelines. Most Policy modules are based on Damian Conway's book Perl Best Practices. However, Perl::Critic is not limited to PBP, and will even support Policies that contradict Conway. You can enable, disable, and customize those Polices through the Perl::Critic interface. You can also create new Policy modules that suit your own tastes.
LibreSource is a versatile collaborative platform and software forge. It is adapted to the collaborative software development, groupware, community leading, e-archiving and Web publishing. On a single server, LibreSource can host several projects, several groups of users, and grant fine-grained access to the resources. Based on Java/J2EE technology, it is a modular Web server that users can customize online by combining resources and rights: wiki pages, forum, trackers, synchronizer, subversion, files, download areas, a dropbox, forms, etc.
glibc-audit is a modified version of glibc for application developers who check their code with an automatic memory access checker such as Purify, Insure++, or valgrind. glibc-audit has been audited and cleaned up so that reports from the developer's use of a memory access checker are more likely to be interesting to the developer, with less "noise" from the C library itself. Also, the r_debug.r_brk protocol has been enhanced to co-operate with a co-resident auditor.
JCSC is a powerful tool that checks source code against a highly definable coding standard for potentially bad code. Standards cover naming conventions for classes, interfaces, fields, and parameters, and the structural layout of classes and interfaces. Each rule is highly customizable. It can also find potential bugs, including empty catch/finally blocks, switches without defaults, throwing 'Exception' types, and slow code. JCSC was inspired by lint.
SMATCH is a neat program designed to locate programming errors in any open source software project. Right now it is actively used to screen out errors inside the Linux kernel. There are two main parts to Smatch. The first is a patch to the gcc sources to screen out a lot of useful information. The second part is a collection of Perl scripts and libraries to analyze the information and report the findings.
