Description of work + goals

Our goal by the end of the semester was to get DXR working. DXR contains components such as Dehydra, Jshydra, Viewsource, and a Modified GCC compiler. We had to essentially build each of these from scratch in an attempt to put it all together and finish in time.

Description of Packages

  • Dehydra

Dehydra is a static analysis tools able to analyze application specif C++ codes. Dehydra can be compared to as a searching tool as well. It is able to display a vast amount of information consisely using Javascripts. This tool is able to help fromo bugs in source codes, which is provides more error checking than C++ is able to by itself. Dehydra is a plugin for GCC, which make it easy to use for projects that supports GCC.

  • JSHyrda

JSHydra is static tool that is able to analyze general JavaScript Code. It was formed with the concept of previous tools Dehydra and Treehydra, which performs C++ code analysis. The backend of this tool, breaks down the Javascript code using a SpiderMonkey Engine. The breakdown of the codes are executed by running Javascripts.


  • Viewsource

Viewsource is a web-based interface to Mozilla's static analysis tools, Dehydra and JShydra. Dehydra is used to analyze C/C++ source code and JShydra is used to analyze JavaScript. Essentially you would take source code and place it into the textbox provided in the web application and select either the JShydra or Dehydra button and view the output.

  • GCC (GNU Compiler Collection)

GCC is a compilation of compilers, and was originally written for the GNU operating system. Here is a list of front end compilers in its collection: C, C++, Objective-C, Fortran, Java, and Ada, as well as libraries for these languages.

Results + What we’ve accomplished

Viewsource was built and has been deployed on one of the CDOT machine’s, everything was ready and waiting for Dehydra + Jshydra.

Both Dehydra and Jshydra where built and finished with no errors that we knew of, although the true test would be when we incorporate GCC with it. So far Viewsource and Dehydra are ready for fedora review while Jshydra still has to be prepared.


  • Dehydra

Our challenge in building Dehydra is there are no prior package release of this tool as we are the first ones to create it, so we had nothing to refer to and check if we are doing everything correctly.

Our solution was to follow the installation guide off the Mozilla Dehydra site, and built a spec file around it. During the process I have encountered lots of small errors, with the help and reviewing Fedoras Packaging outline, we were able to overcome these obstacles. Most of these errors are related to where I install the files at the end of the installation.

At the end, we were able to build the Dehydra package. We created two packages one for the x86-64 architecture and one for the i386 architecture. At this current stage and time we are unable to test out the package to see if it works. We are waiting for our other project (GCC Packaging) to complete in order to test it as they go hand in hand. We have placed our packages in our repo and can be accessed at any time.

Summary and set of conclusions

All of the other fundamental components are built however our project is still in the midst of being complete due to GCC. Once GCC is finished it will be tested with the other components and then GCC and jshydra will be prepped according to the fedora review guidelines and we will have our DXR complete.
