Project Name
Add DTrace Probes and scripts for Mozilla Code base
Project Description
DTrace was created by Sun in OpenSolaris to allow developers to write simple scripts in order to probe and instrument executing programs in a way not possible otherwise. One of the advantages of DTrace is that it allows you to turn on probing when you need it, but not incur an execution penalty with regard to performance (i.e., when probes aren't being scripted, they aren't run). This requires developers to add "probes" to their source code. For example, if you wanted to know when a particular function is entered/exited, get info about what happened, etc. you could add probes to the particular function. Writing the probes is not difficult, however there are hundreds or thousands of probes that Mozilla would like across its code base.

0.1 Release
I am looking at 2 major things for this release.
1) Creating a D Script that will pick up on an existing D-Trace Probe.
2) Make sure that Mozilla Firefox runs on Mac, and the D-Trace script doesnt crash Mac and/or Firefox.
For code submission, I will be submitting the D script I used and the output of the file. The instructions for it are also in the wiki. I would appreciate it if it wasn't edited for any malicious intent.
0.2 Release
1)Work on a bug that is related to D-Trace, hopefully adding probes to a certian location
2)Create a D-Script that can pick up on its basic information when properly implemented.

When I reach the stage where my Probe programs work, I may lend my functionality to other users to see if it works on seperate parts than the areas I am working on. For instance, I can lend the probing technology to a person working on Songbird, or Thunderbird.
Contact me on IRC - nick is Hellwolf_36 if interested. I will be coming online mostly everyday starting Tuesday.
