Pork

Pork is a set of tools built around the elsa C/C++ parser. The primary focus of pork is to provide automated refactoring (Gecko:DeCOMtamination) and static analysis tools for Mozilla2. Pork announcement

Pork is a fork of oink. In the future pork should become a development branch for oink.

More info for pork can be found on Taras' blog.

Requirements

• GCC 3.4.x or older that can successfully build Mozilla. 64bit Ubuntu, 32bit RHEL/CentOS are known to work. 32bit Ubuntu/Debian feature a linker bug that prevents Mozilla from building with gcc 3.4.6.
• MCPP is required for refactoring tools
• SpiderMonkey is required by DeHydra
• Bison and Flex
• patchutils are recommended to manage manual and automatic patches
• MQ extension for hg is recommended. Alternatively, quilt can be used instead.

Tools

Pork is broken down into tools that focus on a specific tasks. The tools can rarely be combined and thus should be applied incrementally.

• DeHydra is a scriptable static analysis tool. It is useful for finding patterns in the codebase. It has been used to find bugs, produce class diagrams and to infer auto-refactoring candidates in the code.

• Outparamdel rewrites code using outparameters to utilize the return value instead. Blog entry

• Prcheck is a static analysis tool which produces patches as output. It is useful for correcting bugs that resulting PRBool behaving more like an int than a C++ bool. Blog entry

• Garburator rewrites nsCOMPtrs allocated on the stack into stack variables to assist the XPCOMGC project.Blog entry

• Squash is now obsolete. It was primarily written to explore how elsa can be utilized to assist with Gecko:DeCOMtamination. Many rewriting strategies and patching code were first implemented in squash.

• PorkVM is a CentOS virtual machine image with a presetup pork + moz checkout.
