This article is part of the series "Around the World with Bazel in Watercolors".
I cannot call New York a trip, as it’s my home, but we do have customers, team members and future customers here. This led to a few events that included working with the team and bringing customers and friends together over food with a touch of Bazel!
Imagine reading this post on your internal Slack:
Please hold off on pushing your PRs for a bit until the patch release is fully cut. We don't have enough capacity to handle all the load and the patch is blocked because of that.
Ouch.
But let's be real: not all builds are made equal - some builds are more urgent than others. Like here, when creating a patch release, and wanting to expedite the builds required for it over others.
Yet there's got to be a better solution than asking everyone else to not push changes.
In the previous Bzlmod post, we covered writing your own Bazel module extensions to adapt your own setup code for dependencies that aren't Bzlmod compatible. However, there are other Bzlmod incompatibilities and related breakages that module extensions alone can't fix, such as forbidden API usage or Windows path length errors.
This post shows you how to patch your dependencies and covers several situations where patching is the only solution. We'll describe how to create and apply patches for your dependencies, if you can't wait for upstream fixes (or contribute them yourself).
EngFlow has multiple entities around the world, one of which is in Colombia. This year we’ve chosen Colombia as the site for our 2025 Leadership Summit, and I added a few days and weekends to explore the country with our team members, see how they live and meet their families. It’s been an incredible experience visiting Medellin, El Retiro, Itagui, Cali and Bogota, and I’ve captured a few learnings from this trip in a blog.
So far, we've covered relatively easy Bzlmod fixes, how to hold runfiles and
pkg_tar correctly, and how to access canonical repo names when absolutely
necessary. Now we'll discuss replacing WORKSPACE statements with your own
module extensions. You can use them to wrap your project's setup macros, and to
adapt external repositories that aren't Bzlmod compatible to work with your
Bzlmodified project.
As we look forward to 2025, we are grateful to our employees, customers, and the broader build community for the continued investment in achieving our mission of making developers productive and happy to keep Engineers in Flow.
In 2024 EngFlow continued our multi-year track record of exponential growth. This year we onboarded some of the most complex and advanced engineering organizations across autonomous driving, e-commerce, SaaS, finance, and chip manufacturing, resulting in significant developer velocity and cloud cost savings for these teams.
EngFlow has become more than a platform provider - we are elevating the developer experience practice for our customers, continuously pushing the cost and performance innovation, passing the savings directly to our customers. We are connecting engineers working on similar technologies to share best practices and talent across the Bazel, Buck2, Chromium, AOSP, and CMake ecosystems. While doing that, we're enriching our customers with music and are making the planet a greener place (read more about this below)!
Between roughly 2006 to 2008, Google developed remote caching and execution technologies to scale its massive monorepo based software development operation. This platform included Forge, the remote caching and execution platform, and Blaze, a tool for building large multilanguage software projects, eventually open sourced as Bazel. The advantages of this original platform were so obvious that it literally sold itself, and ultimately inspired the EngFlow platform.
Today, EngFlow is one of several competing remote caching and execution products now available in the commercial space. This post describes how we continuously benchmark our own product against different configurations to ensure that we offer the best possible value. We hope that sharing our methodology might help you evaluate whether remote caching or execution is right for your organization.
Bazel was announced on March 24, 2015, by unveiling https://bazel.io and dumping code on https://github.com/bazelbuild/bazel. Its development has been somewhat public ever since, but it has never been documented how we got to that point. I was one of the people who started this project, so let me tell you how it happened.
Co-hosted by EngFlow and Google, the build community in Tokyo came together for an afternoon of tech talks and a happy hour filled with beverages and good vibes.
The event went straight into talks, starting with introductory words from our Google host, Philipp and EngFlow Developer Support Engineer Kip. The talks that followed spanned build systems and build issues:
Following the talks, we headed out to a nearby bar for some canapés and drinks, meeting fellow build engineers and enthusiasts from around the region.
The previous two posts in this series showed how to use runfiles mechanisms
and rules_pkg mechanisms to avoid dealing with canonical repository names
under Bzlmod. However, one special case remains: when you need to depend on the
name of a repository directory, either at build time or runtime. This post
explains how to access canonical repository names in a portable way to solve
such problems. We'll use a macro when we can, and a custom Make
Variable when we can't, including when dealing with alias targets.
