Learn how to diagnose and resolve unexpected rebuilds in Bazel by identifying action cache misses caused by environment leakage, non-deterministic toolchains, and absolute paths.
Local Bazel builds pass but CI fails intermittently due to sandbox non-hermetry: missing inputs, env leaks, or runfile issues. Use ordered checks to find and fix the cause.
Learn how to implement Bazel Remote Caching to eliminate redundant builds in CI/CD, including configuration examples and warnings about cache poisoning.
Learn how to enable Bazel remote caching, avoid common pitfalls, and verify that your CI builds are actually reusing cached outputs.
Learn how to diagnose and fix Bazel action cache misses. This guide covers identifying non-deterministic toolchains, environment leakage, and binary discrepancies using execution logs.
Bazel’s remote cache can turn slow monorepo builds into fast, distributed pipelines. Learn how to configure caching, add remote execution, and monitor hit ratios to cut wall‑clock time.
When working with large Bazel workloads, understanding where time is spent during a build can be challenging because the tool aggregates actions across multiple platforms and caches results. Developers often need a reliable way to collect granular timing data for individual rules, sandbox executions, and remote cache hits without interfering with normal buil
Diagnosing Bazel build performance involves collecting timing and resource usage data to pinpoint actions that dominate the overall build latency, while ensuring that the profiling mechanism itself does not significantly distort the results. Because builds may involve remote execution, caching, and incremental changes, the collected metrics must be interpret
Problem Overview Bazel’s remote cache uses content‑addressable storage keyed by the checksum of downloaded artifacts. When the definition of an external repository (e.g., a git_repository or http_archive ) is updated to point at a new commit or URL, Bazel may still reuse a cached artifact if the checksum matches an older version. This can lead to a build tha
