Development - IMPORTANT

This Gitmails version is no longer maintained. Check out the Gitmails Shell port if you want to use a version that is maintained and, hopefully, developed.

If you do not want to use the shell port and prefer the Python version, feel free to fork Gitmails and direct it to whenever path you see fit.

Overview

Gitmails explores that git commits contains a name and an email configured by the author and that version control host services are being used to store a lot of projects.

What Gitmails does is:

  • Query the version control host services for information about an organization, team, group, user or single repository;
  • List all repositories (restricted by authentication) if not on single repository mode;
  • Clone the repository or query the version control host service for the commit history;
  • Analyze the commit history to identify unique authors. Authors are defined by a name and email par.

With these steps, Gitmails can collect all emails found in commit history for a specific target.

Usage

First, you must choose the operation method: collect emails of organization, user or single repository. This can be done by the options: -u --username, -o --organization or -r --repository.

After specifying the operation method, you must set the target. You should pass it right after the operation method: python3 gitmails.py -u some_username, python3 gitmails.py -o some_org or python3 gitmails.py -r some_repo_url. NOTE: gitlab usernames are case sensitive, keep that in mind when trying to collect emails there.

With this basic configuration, Gitmails will clone all repositories for the specified target (or clone the repository in the url) and analyze its commit history. Then, it will print the high level information of the user or organization and finally print, in a "fancy_grid" table (from tabulate), all the Name-Email pars found during analysis.

Useful options:

  • --raw: Will print the results in pure text, no grids, just a comma separated values;
  • -f | --file: Will store the result in the specified file. The results will be in csv with no header format.
  • --include-repositories: Will make Gitmails print the result with information about in which repository the email was found.
  • -p | --path: Specify the temporary path to clone the repositories.
  • -e | --exclude: Ignore specified repositories. Will compare the repository name, if it matches, will ignore the repository and go to the next.
  • --no-cleanup: Will not remove the clonned repositories.
  • --include-forks: Will include forked repositories in the analysis (Only for github).
  • --include-users: If collecting an organization, will collect info about its public members (Only for github).
  • --no-[gitlab|github|bitbucket]: Will not collect information of the specified host service.
  • --run-plugins: Will execute plugins in the collected result.
  • --api: Will try to collect all the information only through API, without clonning repositories. NOTE: Accessing APIs without authentication will cause your IP to be throttled. Also, API only collection is usually slower than clonning the repositories.

Installation

To install Gitmails, you will have to execute the following steps:

  • pip3 install -r requirements.txt
  • Install pygit2 through your operating system package manager.

Debian problems

If you are using Debian (maybe Ubuntu too), the libgit2 package do not work with Gitmails. To solve this, you will need to compile the libgit2 manually. The following steps should enough:

wget https://github.com/libgit2/libgit2/archive/v0.27.0.tar.gz && \
      tar xzf v0.27.0.tar.gz && \
      cd libgit2-0.27.0/ && \
      cmake . && \
      make && \
      sudo make install
ldconfig
pip3 install pygit2

Or execute the debian install script.

Docker

You can also use the docker version of the tool by issuing the following command:

  • docker run -it giovanifss/gitmails --help

Note that if you want to write to a file, you will need to mount a docker volume:

  • docker run -v /tmp/output:/opt -it giovanifss/gitmails -f /opt/result.txt
