{Fast, Correct, Secure} - Choose Three - Yannic Bonenberger & Antonio Di Stefano, EngFlow

Tuesday October 15, 2024 10:00am - 10:30am PDT

Hahn Auditorium

Bazel is well-known for its commitment to deliver both fast and correct builds at scale. However, ensuring trustworthy development and deployments to production goes beyond just accurate execution tracking. It encompasses the entire pipeline, including the integrity of the host environment, the security of third-party dependencies, and the reliability of remote caching and execution systems. In this talk, we will explore the advanced features Bazel offers for creating correct and secure builds. Additionally, we will address existing challenges in generating Software Bill of Materials (SBOMs) and maintaining reliable audit trails, so your process can achieve the highest Supply Chain Levels for Software Artifacts (SLSA) compliance.

Not Going the Distance: Filtering Tests by Build Graph Distance - Alex Torok, Aurora Innovation

Tuesday October 15, 2024 12:00pm - 12:10pm PDT

Hahn Auditorium

At Aurora, many of the tests that our developers rely on are computationally expensive simulations that rely on specialized and expensive GPU hardware. We use tooling similar to bazel-diff and target-determinator to figure out what targets have changed between two git revisions, then run specific tests based on those targets. This method scaled well until our build graph reached a certain size. Changing common code triggered a larger and larger number of low-signal tests. This slowed down developer velocity due to having to wait on more tests and being more likely to get hit by a flaky test failure. We updated Aurora's in-house changed target detection tool to emit build graph distance metrics that measure the distance between a changed target and a directly modified file. This distance metric allows us to confidently skip running some tests to avoid the issues described above. In this session, I will discuss how we compute build graph distance metrics and the ways that we use them to power workflows that increase developer velocity and improve mainline stability in a domain rich with expensive-to-run tests.

Nix and Bazel: The Odd Couple of Build Tools - Jesse Schalken, Canva

Tuesday October 15, 2024 12:10pm - 12:20pm PDT

Hahn Auditorium

A talk on why Nix and Bazel does not pair with each other well, recommending to use Bazel and bzlmod instead of Nix. Specifically, Nix is a package manager that is often misintegrated into Bazel. It is incompatible with the Bazel ecosystem in that * Nix artifacts are not relocatable, breaking Bazel remote execution when Nix outputs are in the build graph * Nix binaries are incompatible with FHS and rulesets that expect FHS because binaries are located in Nix store * Users who are familiar with Bazel are (usually) not familiar with Nix. Our engineers are often unable to self-serve patches to Nix packages, and they are also unable to use the testing framework provided by Bazel (which are familiar to most engineers) to validate their patches because of the steep learning curves * At monorepo our size, it is not rare to see Nix expressions that produces several thousand derivations that each reference large sets of build inputs. Expression evaluations are often so slow that nix-builds are in the critical path during analysis phase, even though outputs are already in the Nix cache. Nix flakes can help but it has an awkward git integration which does not work very well in large monorepos

Remote Execution with Rules_nixpkgs: Design and Deployment - Guillaume Maudoux, Modus Create

Tuesday October 15, 2024 1:30pm - 2:00pm PDT

Hahn Auditorium

rules_nixpkgs brings the power of Nix to Bazel dependencies. It provides access to the large nixpkgs package repository and benefits from hermeticity and declarative configurations that are dear to both the Bazel and Nix communities. But despite all the benefits, it still comes with one major downside. It makes remote execution of Bazel actions next to impossible but for some restricted use cases. In short, rules_nixpkgs and remote execution are like oil and vinegar. It takes effort to blend them into a tasty vinaigrette, but once you do, you'll never look back to your plain old builds. In this talk, we will introduce the challenges posed by this integration. Various solutions have been proposed over the years. We will explain how we chose one by looking at how these solutions propagate the necessary information across their components. We will then delve into the specifics of our design, explore technical aspects of our deployment, and discuss issues and benefits observed in practice. The last part will focus on performance metrics. We will share our understanding of the impact this change had on our infrastructure and, most importantly, on developers.

Rules_lint: Formatting and Linting All Languages - Alex Eagle, Aspect Build Systems

Tuesday October 15, 2024 2:00pm - 2:30pm PDT

Hahn Auditorium

Tools for formatting code and performing static analysis are available in some of Bazel's language rules, but their approaches differ. This means each language has to be setup separately, and product engineers may have to learn multiple workflows across the full stack. rules_lint provides a consistent abstraction for plugging in language-specific tools, and avoids requiring changes either in language rulesets, or in user's BUILD files. In your repository you setup a single "format" workflow, and a single "linting" workflow. This talk explains why these two workflows are distinct. We'll explain how to integrate new tools into rules_lint, options for installing it into your repository, and show some nice ways that results can be integrated into developer workflows.

We want to demonstrate how to use Bazel to compile C++ source code across various operating systems (e.g. Linux, Windows, and macOS) and processor architectures (e.g. AMD and ARM). We will show how to - Create a Bazel C++ toolchain, that serves different host and target operating systems and architectures - Make Bazel automatically pick the right toolchain configuration based on host and target system - Compile natively as well as cross platform - Create “universal binaries” by running several toolchains in the same build, creating a single artifact, that can run on multiple architectures - Use the platform information to name packages, switch dependencies, skip targets, … We will show how to achieve all of this by using native Bazel features like multi platform builds, toolchains, transitions, and sufficiently hermetic toolchains.

Interoperating Bazel and Other Build Systems - Alexander Neben & Zack Winter, MongoDB

Tuesday October 15, 2024 3:15pm - 3:45pm PDT

Hahn Auditorium

At MongoDB we do not have one central codebase or only one language. As we continue to scale this fractured ecosystem is harder to maintain so we needed to migrate these disparate repos to a shared development platform. Our first step in that journey is migrating large repos to be built with Bazel so that the build team can make a feature once and it can benefit all of our developers. MongoDB’s approach to doing this is novel because we were able to de-risk these projects by supporting significant interoperability during migration. The downside, which is what most of this talk will be about, is dealing with the large amount of configuration in the build system. For example, the MongoDB C++ codebase had ~112 configuration options and remote compilation (not with RBE) before this process began and before converting even a single target we needed to support many of these configuration options and two remote execution environments. We are going to speak about the tools we used and created for these transitions, techniques we used for maintaining our hybrid build system, and how you too can switch to Bazel gradually and gently with the enthusiastic support of your organization.

Tuesday October 15, 2024 4:40pm - 4:50pm PDT

Toolchains and platforms are there to last, and yet my experience shows that they can be challenging for newcomers, and can still surprise experienced Bazelistas. Some time ago, a debug session led me to read the actual source code, and I ended up refactoring the messages dumped by `--toolchain_resolution_debug` in the hope to make them more intuitive and self-explanatory. This session will present the new message format and build upon its structure to explain the algorithm that drives platforms and toolchains selection. Attendees will build a clear mental model of that core part of Bazel. Additionally, the presentation will insist on the importance of crafting self-explanatory messages, along with the tradeoffs involved. Debugging toolchain issues is now easier than ever, and a little bit funny.

Rules_variant: Developer Friendly, Multiplatform Builds - Aleksander Gondek, ASML

Tuesday October 15, 2024 4:50pm - 5:00pm PDT

Hahn Auditorium

Creating Bazel definitions which allow to build the same targets in multiple configurations at once (i.e. different target platforms) is possibly one of the most convoluted parts of any larger project. Bazel has rich and powerful tooling that supports such an approach, yet it is not yet exposed in an approachable way. Frequently, it leads to opaque macros and custom rules whose sole purpose is to apply some transitions, naming conventions, and more, all of which contributes to Build definitions that are not developer friendly and require a higher level of Bazel familiarity to work with. `rules_variant` is a new meta-ruleset (based on `with_cfg.bzl`) designed to address that particular issue. Desired variants (essentially Bazel configurations) are stored in a JSON file and any Bazel rule may decide to be “pinned” to a certain set of said variants, simply by referencing it via an additional attribute. From the developer’s perspective it is as simple as referencing additional names, if the Bazel target has to be built in an additional “flavor” (with specific settings). This talk showcases the incredible flexibility and readability that comes from the aforementioned approach.

Why We Should Care About Test Execution Output in Safety-Critical Industries - Markus Hofbauer, Luminar Technologies

Tuesday October 15, 2024 5:00pm - 5:10pm PDT

Hahn Auditorium

In highly regulated industries such as automotive, aviation, and medical, test artifacts are often essential for further reporting. Automotive SPICE (ASPICE) or AUTOSAR from the automotive field requires detailed, reproducible reporting on executed tests. Companies such as BMW or NVIDIA use Bazel to build their software. However, Bazel does not cache test execution output, but only that a test was executed. To address this, some companies have resorted to forking Bazel and implementing this feature on their own which causes maintenance overhead and impedes collaborative Bazel improvements. Our proposed solution is to treat the test binary as a tool and run it as part of the Bazel build phase. This way, we can depend on the test output for further processing such as skipping integration tests if unit tests fail, collecting output artifacts such as human-readable test reports and machine-readable coverage reports, as well as making coverage collection depend on test outputs. Thanks to Bazel’s caching, the test is not executed again in the test phase which makes this solution an acceptable tradeoff.
