Hacker News with Generative AI: Continuous Integration

DIY automation using only Linux (medium.com)
You may sometimes feel overwhelmed in a world where CircleCI, TeamCity, JFrog, Jenkins, and many other solutions manage continuous integration and auto-deployment. When you work with security products, you also have some confidentiality concerns. Having a good tutorial to create straightforward automation is quite handy.

Prefer tee -a, not >>, in CI (huonw.github.io)
Shell scripts sometimes have to append data to a file. Redirecting output with >> is the conventional way and works fine, but using tee -a instead is a usually better default, especially in continuous integration. It’s just as easy and gives automatic introspection: the same value is printed to stdout and so appears in normal logs too.

Faster CI with Selective Testing (mill-build.org)
Selective testing is a key technique necessary for working with any large codebase or monorepo: picking which tests to run to validate a change or pull-request, because running every test every time is costly and slow. This blog post will explore what selective testing is all about, the different approaches you can take with selective testing, based on my experience working on developer tooling and CI for the last decade at Dropbox and Databricks.

Working with Igalia to Improve RISC-V LLVM Continuous Integration (riseproject.dev)
The LLVM project provides a very widely used and actively developed suite of compiler and toolchain technologies: including Clang, the LLVM middle-end optimizer and backend code generator, MLIR, LLD linker, and much more. While RISC-V LLVM support has progressed significantly, a key area that needed attention was the limited level of continuous integration (CI) for the RISC-V target.

Your CI pipeline isn't ready for AI (morgante.net)
In developing my AI codegen agent, I’ve surprisingly been far more frustrated by CI/testing systems than any unreliable LLM API.

The Many SHAs of a GitHub Pull Request (kenmuse.com)
Many people don’t realize it, but pull requests actually have multiple “identities” when an Action workflow runs. There are actually multiple SHAs that represent different parts of the lifecycle during a continuous integration build. This can be confusing for teams that are trying to implement advanced processes, and it often lead to mistakes. In some cases, it leads to a misunderstanding – thinking that the build is testing the branch itself instead of a simulated merge to the target branch.
