A pull request's firmware step took 358 s: 260 of them rebuilding the framework that was already in the volume, because the platform decides by sdkconfig.defaults in the project folder, which is generated and not in git, so no fresh checkout had it. It is now kept in the volume, inside the libraries it describes, and copied into the checkout; the platform still checks its hash against platformio.ini. The version was a -D on every command line: each commit recompiled everything, and no cache could help. scripts/version.py now writes one generated header, read by one file. PlatformIO's build cache in the volume for pull requests' firmware, ccache for the host tests (built for coverage, which the build cache can't keep), the tools in a venv in the volume, and a tag builds its firmware once. A release still compiles its own sources from nothing. Measured on fresh copies of the tree: the firmware step 358 s to 27 s (a new version and one changed file), tests and coverage 49 s to 33 s, a local rebuild with nothing changed 77 s to 13 s.

The roro9stack site
Source of https://roro9stack.net (docs/milestones/W1.md): a Zola site. The home page, an Install page with a browser flasher, and the list of releases so far; the user guide, how-tos, FAQ and developer docs come next.

Build and look
docker run --rm -u "$(id -u):$(id -g)" -v "$PWD:/repo" -w /repo/site ghcr.io/getzola/zola:v0.22.0 build # writes ./public
docker run --rm -u "$(id -u):$(id -g)" -p 1111:1111 -v "$PWD:/repo" -w /repo/site ghcr.io/getzola/zola:v0.22.0 serve --interface 0.0.0.0
python3 site/tools/check_site.py public # what the pages promise, kept
Or zola build with a Zola of your own, in site/ (or zola --root site build from the root). The output goes to public/ at the root of the repository, not into site/: output_dir in config.toml, and git ignores that directory. The build reads the latest release and the list of releases from the Gitea API (load_data); if the server can't be reached, the pages say so instead of failing.
Publishing
The web server pulls main and runs zola build, as for the blog. CI (.gitea/workflows/site.yml) builds the site and runs the checks when site/, docs/, README.md or CONTEXT.md change; the firmware workflow skips a change that touches only those.
Things to know
-
The Install page needs Caddy's help. Gitea's release downloads carry no CORS header, so the page asks the API from the browser only if Caddy, in front of Gitea, allows this origin:
@releases { method GET HEAD path /twisla/roro9stack/releases/download/* /api/v1/repos/twisla/roro9stack/releases* } header @releases Access-Control-Allow-Origin "https://roro9stack.net" header @releases Vary OriginWithout it the page says it can't reach the release server and points to the esptool steps.
-
No third-party requests. Fonts and the flasher library are served from here;
tools/check_site.pyfails the build if a page loads anything from another origin. -
Illustrations.
