simple script for profiling moz tools

moz-profiler

CLI tool for profiling Mozilla Conduit applications. Currently compatible with: MozPhab.

Setup

After cloning this repo, execute the following commands:

python -m venv venv
source venv/bin/activate
pip install -r requirements.txt
pip install -e .

To confirm the setup worked, you can run moz-profiler -h.

Usage

To begin using the profiler, navigate to the directory of the application you're profiling.

Currently, it only supports MozPhab, so it should be review/. Then execute:

moz-profiler attach moz-phab

This will do a couple of things:

• it should detect your .bashrc and add some environment variables
• creates a virtual environment in the directory for its usage
• installs any dependencies in the environment

This updates your PATH to include moz-profiler/bin, which will intercept any calls made to moz-phab, and forward them to the profiler.

After its attached, it will start storing profiles in moz-profiler/.profiles.

snakeviz is a dependency, so if you want to inspect any of the profiles, run snakeviz PROFILE_PATH.

You can also execute moz-profiler diff for a simple comparison between the last two profiles.

When you no longer wish to profile the application, execute moz-profiler detach moz-phab.
