kristianwindandClaude Opus 5 a1f6e54f9d The smoke test could not fail, and other people's eyes
Four fixes, two of them serious, three of them found by the session porting
this into subscriptions.

1. THE SMOKE TEST COULD NOT FAIL. `wp eval-file` runs the file through eval()
   INSIDE A METHOD, so the top level is function scope. `$wc_edm_failures = 0`
   at the top and `global $wc_edm_failures` in the helper were two different
   variables: the helpers incremented the real global, the verdict read the
   local, and the local was always zero.

   Measured rather than reasoned. A deliberately false assertion added to the
   unmodified file:

       FAIL  DELIBERATE FAILURE — this run must go red
       All assertions passed on WordPress 7.1 with WooCommerce 11.1.0.
       EXIT=0

   and with the fix, the same forced failure:

       FAIL  DELIBERATE FAILURE — this run must go red
       1 assertion(s) failed on WordPress 7.1.
       EXIT=1

   The FAIL lines always printed, so failures found by reading the output were
   real finds. What was broken is the CI gate: a regression on either forge
   would have gone green. Four lines at the top now prove the counter reaches
   the verdict before anything relies on it — this is the one file whose whole
   job is to be able to go red, so it checks that it can.

2. `git ls-files` QUOTES NON-ASCII PATHS. "TESTMILJØ.md" comes back as the
   literal string "TESTMILJ\303\230.md", which matches no pattern in
   .distignore, so the file is kept — an internal document walking into the
   release zip with nothing said. Fixed in ci/dist-files.sh and in
   ci/static.sh's trailing-?> check, which had the same bug and would have
   silently skipped the file it exists to check. Verified by adding such a
   filename and watching it be excluded. `done < <(...)` rather than a pipe, or
   the loop runs in a subshell and the failure counter stops incrementing.

3. THE FEED CACHE WAS SIX HOURS, and Kristian hit it: a release published and
   his shop shown nothing. The reasoning ("WordPress checks twice a day") was
   wrong. WordPress gates its own check by screen in wp_update_plugins() — one
   minute on Dashboard → Updates, one hour on Plugins, 2–12 hours in the
   background — so WordPress is already the rate limiter and a longer cache
   only hides releases underneath it. Fifteen minutes now, pinned by an
   assertion.

4. The wp_update_plugins() assertion made a real HTTP request, because the
   force-check tests had just deleted the transient. It passed only because
   this feed repo is public, which made it measure the environment rather than
   the code. Re-primed first.

ci_in_container() replaces the inline docker plumbing in ci_php(), taken from
the subscriptions port: the script goes in as a file rather than interpolated
into `sh -c`, and --entrypoint sh matters for images whose entrypoint swallows
its arguments.

# Using this setup in another plugin
Everything here was built to be lifted into the next WordPress plugin. Nothing
under `ci/` knows this plugin's name except `ci/plugin.conf`.
There is no shared repository and no reusable workflow to `uses:`. That is
deliberate: these repositories live on two forges, and a cross-forge
`workflow_call` resolves on GitHub and fails on Gitea. Copying six files and
editing one is a smaller cost than a dependency that works in half the places
it runs.
## The port
**1. Copy these, unchanged:**
```
ci/ every script; plugin.conf is the only one you edit
.github/workflows/ ci.yml, compat.yml, release.yml, auto-merge.yml
.gitea/workflows/ ci.yml, compat.yml, release.yml, README.md
.distignore
```
**2. Rewrite `ci/plugin.conf`** — five values, all commented in the file:
```sh
PLUGIN_SLUG=your-plugin
PLUGIN_MAIN=your-plugin.php
TEXT_DOMAIN=your-plugin
NEEDS_WOOCOMMERCE=yes # no, for a plugin that does not need it
SITE_TESTS="tests/fixtures.php tests/smoke.php"
```
**3. Adjust `.distignore`** for that plugin's internal documents. Everything
left in `wp-content/plugins/` can in principle be fetched over HTTP from a live
shop, so notes and tooling stay out of the zip.
**4. Write `tests/fixtures.php` and `tests/smoke.php`.** These are the only
genuinely new work. Use this plugin's as the shape: `wc_edm_ok()` /
`wc_edm_is()` accumulate failures so one run reports all of them, and the file
exits non-zero at the end. They run under `wp eval-file`, so WordPress and
WooCommerce are fully loaded and every API is the real one.
**5. Copy `includes/class-updater.php`** and rename the class, the `TRANSIENT`
constant, the plugin-file constant and the user-agent string. Then add to the
plugin header:
```
Update URI: https://gitea.nolimit.dk/kw/your-plugin
```
and instantiate the updater **before** any "is WooCommerce active" gate — a
shop with WooCommerce switched off for an afternoon must not quietly stop
receiving fixes.
Three things in that file are load-bearing and none of them look it:
- 🔴 **`offer_update()` answers even when the installed version is already
current.** It is tempting to return `false` there — there is no update, after
all — and that one line is what silently removes the **Enable auto-updates**
link from the Plugins screen. `WP_Plugins_List_Table` sets
`update-supported` only for plugins it finds in the update transient's
`response` **or** `no_update` list; a plugin that stays silent is in neither,
and wp-admin says "Auto-updates are not available for this plugin." The
plugin looks perfectly configured and can never auto-update.
`tests/smoke.php` asserts the rendered table, not the intention.
- **Set `icons`.** Without it Dashboard → Updates shows a generic grey plug.
Point it at the shop's own copy (`PLUGIN_URL . 'assets/icon.svg'`), not the
release host: one fewer thing that must be reachable for wp-admin to render,
and it cannot go mixed-content on an HTTPS shop.
- **`Update URI` also switches wordpress.org off** for this plugin, from
WordPress 5.8. Remove the header and a .org plugin that happens to share the
slug could be pushed onto a shop running yours.
🔴 **Keep the feed cache short — WordPress is already the rate limiter.** It
gates its own check by screen: one minute on Dashboard → Updates, one hour on
the Plugins screen, 2–12 hours in the background. This filter only runs when
that check runs, so any cache longer than that cadence simply hides new
releases underneath it. Ours was six hours "because WordPress checks twice a
day anyway", and the symptom was a release going out and the shop being shown
nothing. It is fifteen minutes now, and `forget_on_force_check()` drops it
entirely on the **Check again** link.
**6. Make the Gitea repository public**, or point `Update URI` at a separate
public releases-only repository. Every shop reads that feed without
credentials; `ci/publish-release.sh` fails the release with this instruction if
it cannot.
## What you get
- `ci/static.sh` — syntax on the oldest and newest PHP, the direct-access
guard on every shipped file, no debug leftovers, no short tags, text domain
on every translation call, one version stated once across header, constant
and readme, and a warning when the compatibility headers have gone stale.
- `ci/site-test.sh` — a real WordPress + WooCommerce at any versions you name,
including `nightly` and `beta`, failing on any deprecation from your own code.
- `ci/build-zip.sh` — an installable zip, checked for the main file, for a
single top-level directory named for the slug, and for leaked tooling.
- `compat.yml` — the weekly run against the next WordPress and the next
WooCommerce, and a pull request that bumps the compatibility headers once
that run is green.
- `release.yml` — tag, test, build, publish, then read the feed back with no
credentials to prove a shop can download it.
- `ci/update-smoke.sh` — install the previous version into a throwaway shop and
let WordPress update it by itself. The only check that proves the whole chain.
- Assertions that the **Enable auto-updates** link is actually offered, built
from the real `WP_Plugins_List_Table`, and that the update offer carries an
icon that exists in the release.
- `ci/workflows-in-sync.sh` — fails when the two workflow roots drift, which is
the only way to notice that a workflow stopped running on Gitea.
## Running these locally: `git add` first
Every one of these scripts derives "what ships" from `git ls-files`, which
reads the **index**. An uncommitted file is therefore invisible to
`ci/dist-files.sh`, to the release zip, and to the copy that goes into the test
site.
That is deliberate — it is what catches a file that was written, referenced and
never committed, which is a release that is missing a file while every local
test passes because the file is sitting right there in the working tree. But it
also means running any of this before `git add` tests a release without your
newest file, and the failure is silent: the check does not complain, it just
measures something else. It cost two rounds here, once on
`includes/class-updater.php` and once on `assets/icon.svg`.
If a script reports something you just fixed as still missing, `git status`
before you debug the script.
## Two guards worth understanding before you move them
**`.gitea/workflows/` hides `.github/workflows/` completely.** Gitea uses the
former if it exists and never merges the two. Adding one Gitea-only workflow
switches off CI for the whole repository there, with no error and no run to
click on — it looks exactly like a runner that has not picked the job up. Every
workflow that must run on Gitea has to be in that directory.
**The release reads its own feed anonymously afterwards.** A private repository
and a release with no zip attached both produce a page that looks perfect to
anyone logged in, and an update that no shop is ever offered. A check that
sends a token is the false positive that hides exactly that.
**A forge's own download URL is not the address your users can reach.**
`browser_download_url` is built from the forge's configured root URL;
`gitea.nolimit.dk` reports `http://57.129.89.117:25001/...` there. The updater
rebuilds the address from the `Update URI` header and keeps only the path. This
one hides particularly well: a CI job on the same network reaches that raw IP,
so following the reported URL goes green and only a real client outside fails.
## Candidates already in the fleet
`spool` and `subscriptions` are both WooCommerce plugins with some of this
already: `spool` has an earlier version of the throwaway-site script, and
`subscriptions` has the hygiene checks and a `.distignore`. Neither has the
version matrix, the compatibility schedule or the updater. Porting them is
steps 1–5 above.
