This -is achieved by injecting code into a target process, along with dynamically -generated assembly hook stubs. One of the major goals was to skew performance -timings as little as possible. This lead to a design in which the log buffer -(which is called the playground) is kept within the process, and the logger -routines use atomic instructions to log their events to this buffer. At the -end of the processes lifetime, this buffer is pulled out of the process and -used to generated JSON output. In addition to hooking system call activity, -other hooks of interest have been written, including heap allocation functions. -Symbols are supported with a command line flag. This works by capturing the -process shutdown, and doing an intrusive symbol attach with dbghelp.dll - -NOTES: - - You should copy dbghelp.dll from a windbg installation into this directory. - The version shipped with Windows is old, and symbol support won't work. - - You will need a bit of cygwin if you want to use the Makefile. Otherwise - it is pretty clear how to build the files manually. - - The output JSON data will be printed out stdout. It is likely that you - will want to pipe the output of this program into a file. - -Dean McNamee <deanm@chromium.org> |
