From 0fec7e30e9e8b4c39c5627b2c22fd7652de149ce Mon Sep 17 00:00:00 2001 From: aitrawog Date: Thu, 15 Oct 2026 08:08:00 +0200 Subject: [PATCH 1/4] =?UTF-8?q?feat(verb):=20pin-closure=20=E2=80=94=20the?= =?UTF-8?q?=20transitive=20closure=20of=20a=20pin=20advance,=20iterated=20?= =?UTF-8?q?to=20a=20fixed=20point?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adopting a pin in a multi-module repo is not one edit: each module that pins the repo also pins its SIBLINGS, so advancing one pin surfaces the next module's breakage, and the next. `pin-closure` answers the whole question in one word: compile the composed set, collect EVERY failing module, classify each failure as a BUMP (a published version already carries the fix) or an EDIT (none does — that module needs its own cutover), and iterate to a fixed point. - `pin_closure.go` — resolve the pair, write a go.work overlay over the anchor module plus any already-composed dirs (they win over the pins), build, parse the failures into module verdicts, classify against the module the FAILING PACKAGE belongs to (these repos tag both the repo and the subdir module, and the repo-root tag can already be fixed while the tag a consumer pins is not), and report an EMPTY closure, a BUMP list, or a REFUSED advance naming the EDITs. - `schema/task.cue` + `params/cue_types_gen.go` — `#PinClosureInput` (anchor, compose, module_prefix); the generated types are REGENERATED from the schema with `charly candy params` (drift gate `--check` clean), which is also how the cue_types_gen conflict against current main was resolved. - `plugin.go`/`verbs.go`/`charly.yml` — declare and route the sixth maintenance verb; the candy's capability probe now asserts all nine (three task classes + six verbs). - `AGENTS.md`/`README.md`/`scripts/gate-task.sh` — the five-to-six arithmetic in the same change (R5: no stale count survives), and the repo's own live gate DRIVES the new verb: a compiling set must report EMPTY, and a module whose package does not compile must be classified EDIT with the advance REFUSED — the shape that must never be silently "adopted". - `pin_closure.go runGo` — a workspace build must be hermetic about `-mod`: workspace mode forbids it outright, and this repo's own gate exports `GOFLAGS=-mod=mod` for its charly build, so the fixture run inherited it and failed with a flag error the operator never set against the verb. Measured by the gate section itself; the sanitizer drops `-mod` and keeps every other flag. Re-cut onto current origin/main (the previous tip was 33 commits behind and main had moved verbs.go), so the tree is gated on the base it will merge into. Gate on this tree: gofmt clean; go build ./... rc=0; go vet ./... rc=0; go test ./... rc=0 (incl. the new TestGoFlagsWithoutMod); charly box validate rc=0 (0 warnings); `charly candy params plugin-task --check` rc=0 (no schema drift); `scripts/gate-task.sh` PASS on a fresh charly build carrying this candy — command:task + all six maintenance verbs executed live.

All three were right, and two were defects in the product rather than in its proof: 1. The version lookup and the replace key did not agree. `newestModuleVersion(anchor, f.Pkg)` was handed a PACKAGE path while `replaces[closureModule(f.Pkg)]` was keyed on the 3-segment "repo root" — so for a subdir module (github.com/opencharly/plugin-box/candy/plugin-box) the lookup asked the toolchain about a path that is not a module (BUMP unreachable, every failure forced to EDIT) and the replace, where it was written, targeted the wrong module. `moduleOf` now ASKS the toolchain (`go list -f {{.Module.Path}}`) and both the lookup and the replace use that one path; `closureModule` is the documented fallback and no longer claims a resolution it never did. 2. `writeOverlay` hardcoded `go 1.26.4` into every generated workspace, over-constraining every closure build to one toolchain (a module declaring go 1.24 was built under a workspace demanding 1.26.4) and failing on an older host. The `go` line is now the ANCHOR's own directive (`workspaceGo`), with a conservative floor only when its go.mod cannot be read. 3. The headline — "iterate to a fixed point" — had no witness: both gate fixtures end at rung 1 with nothing adopted, so the BUMP/adoption/re-compose/second-rung path never ran. It now does, hermetically: TestRunPinClosure_IteratesToAFixedPointAfterABump builds a real three-module fixture (a pinned dep whose own package does not compile, and a newest version that does), swaps only the version-lookup seam, and requires rung 1 to see the breakage, classify BUMP, ADOPT it, and rung 2 to compile. Reverting fix 1 makes that test fail with the module key it names, which is the proof it is testing the fix rather than the fixture. An adopted module is now replaced by its DOWNLOADED DIR when the version lookup resolved one (adoptionTarget): the source is already on disk, and a version form would make the next build re-resolve it — needing the network mid-build and, for a module the registry cannot serve, reintroducing exactly the failure this verb exists to find. Gate on this tree: gofmt clean; go build ./... rc=0; go vet ./... rc=0; go test ./... rc=0 (incl. the three new tests); charly candy params plugin-task --check rc=0 (no schema drift); charly box validate rc=0 (0 warnings); scripts/gate-task.sh PASS on a fresh charly build carrying this candy.

Fixed at all three sites. - `defer os.RemoveAll(workDir)` left the error unchecked (errcheck).

RCA, and the control that missed it: this repo's AGENTS.md lists golangci-lint as part of the local gate (under the module's own toolchain, pinned in ci.yml), and the pre-push gate I ran was gofmt + build + vet + test + box validate + the live gate — every one of those is GREEN on the round-3 head while CI's lint was red, so nothing I ran could have caught it.
