Static-linked CGO binaries using musl and Zig

2025-02-15

The ability to produce statically-linked binaries by default in Go is one of the many good reasons why I appreciate and use it. Being able to copy or move only a single file around across all sorts of locations without worrying too much about missing libraries or runtimes has definitely saved me a lot of annoyances many times over. However, working on hedge-cb, and therefore, CGO, for the past few days, reminded me once again how much of a good thing static binaries are.

Cluster membership management on AWS

2025-02-07

In continuation with my previous post, I have now finished porting hedge to AWS. It’s a trimmed-down version for now; only the features directly related to cluster membership are ported. I decided to make a separate repo, called hedge-cb (in keeping with the -cb theme), instead of updating hedge directly. And it’s mainly due to CGO. I didn’t really fancy the idea of introducing CGO to hedge as it could break a lot of the CI builds at work.

Distributed locking on AWS (ClockBound)

2025-02-02

After some testing time, I now have a working port of spindle in AWS. There were some slight changes from the original library to account for some of the differences between Cloud Spanner and PostgreSQL, but not really by much. It’s called spindle-cb, if you’re interested. It’s still half the battle though; I still have to port hedge as well before I could really use it for some of the planned projects in my pipeline.

AWS ClockBound client for Go (update)

2025-01-27

A week ago I published a short blog about clockbound-client-go. After some testing, turns out there’s an issue in reading the actual time from ClockBound’s shared memory segment; it seems to provide only the elapsed time since boot. However, using the Rust client and the FFI bindings produce the correct results. Either there is a problem in the code that reads the shared memory segment, or the SHM contents are wrong.
