Notes from week 33
This week, six million Tessera S3 objects were renamed. ocaml-gdal was extended to handle vector formats. FreeBSD CI performance investigations and OCaml compiler updates. Further work on day10 and OCaml CI.

A big week, with a couple of long-running efforts finally wrapping up: the Source Cooperative mirror is essentially complete now that we have direct write access, and the three-week Ceph resize has converged. Elsewhere, a slow-down in the g…
The main threads: making day10 a native OCluster job type, porting opam-health-check to use day10, keeping the CI dashboards ahead of both a scraper farm and the opam 2.6 alpha, and a lot of Tessera. New v2 “student” models, the v1.1 mirror…
OCaml is a pragmatic functional language: type-level tricks for safe code, careful buffer allocation for fast code. A scratch buffer in ocaml-wire raced under OCaml 5 domains; memtrace and ThreadSanitizer show both sides.
Porting Tailwind to OCaml needed a CSS parser. The parser grew a typed AST, and a structural diff and a minifier fell out of it. Cascade 1.0.0 is that toolkit, and it turns out to be competitive with the minifiers people actually use.
A tour of Theo, an OCaml BDD library with complement edges for O(1) negation, ephemeron-based caching, and theory support for reasoning about version constraints and equality, turning logical equivalence into a pointer comparison.
Last week I updated the OpenBSD workers to OCaml 5.5.0 and took that opportunity to deploy OpenBSD 7.8. Shortly after, issue#1061 was opened as jobs randomly failed with an opam parse error.
While I typically write posts as I go, I’ve only managed one this week because there’s been a lot going on. To catch up, I’m going to try to write a summary of the week instead.
On the base image builder, we have recently seen a significant increase in the number of times we hit the Docker rate limits on manifest pushes. Most of these work on the second attempt, but this week, a new class of permanent manifest push…
The Windows workers in the windows-x86_64 pool have a habit of quietly falling off the cluster. The ocluster-worker service is still RUNNING, but the scheduler lists the worker as disconnected.
Development update for ocgtk (a set of GTK4 bindings for OCaml), including upcoming support for signals and interfaces, expanded GLib type coverage, and packaging improvements to support other operating systems.
Scaleway provide the RISC-V workers for OCaml CI, and they have been down for about a week with no real evidence that they’ll be back anytime soon. I can’t provision any new ones as they are “temporarily out of stock”.
