git_bayesect introduces a Bayesian approach to git bisect, using probabilistic inference to identify commits where event likelihoods change, such as flaky tests. It employs Beta-Bernoulli conjugacy and entropy minimization for efficient commit selection, offering a more nuanced alternative to traditional binary bisection. The tool is installable via pip or uv and includes commands for recording observations and setting priors.
Background
Git bisect is a standard tool for finding commits that introduced bugs, but it relies on binary pass/fail outcomes and can be inefficient for probabilistic events like flaky tests. Bayesian methods offer a way to incorporate uncertainty and prior knowledge into the search process.
