From d051278e01b63cbd8f4daa83cb65f665dc4fb929 Mon Sep 17 00:00:00 2001 From: Manu Lorente Date: Fri, 10 Jul 2026 04:10:02 -0600 Subject: [PATCH 1/3] fix(env): seed machine.json so update/mem resolve the real checkout MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit On a fresh machine nothing writes ~/.config/dotfiles/machine.json, so the phantom contract default DOTFILES_REPO_DIR=$HOME/Projects/dotfiles propagates through the ADR-025 cascade to every consumer that resolves via ResolvePath: `dotf update` reports "not a git repo" and no-ops (exit 0), and `dotf mem` prints "run setup" though setup ran. Consumers using the RepoDir() git walk-up (secrets, spec) were unaffected — two contradictory answers in one binary. - Add `dotf env set `, the write-side counterpart of `env path`: validates the key against the contract, merges into machine.json preserving other overrides, writes atomically. setup-linux.sh / setup-windows.ps1 call it to seed DOTFILES_REPO_DIR to the checkout before `dotf env generate`. - repoForUpdate() and the mem resolvers fall back to the RepoDir() walk-up when the cascade value is not an existing directory. - Add a `dotf doctor` check that FAILs when the DOTFILES_REPO_DIR cascade resolves to a phantom/missing path (mirrors what update/mem see, no walk-up masking), plus Go unit tests and an integration bats asserting setup seeds machine.json.

Setup is the +natural seeder — it runs *from* the checkout, so it already knows the answer. + +Source: issue #696 (audit process-audit-2026-07-07 §4 P3, CONFIRMED). + +## What + +- **A — root cause. New `dotf env set `** (write-side counterpart of + the existing read-side `dotf env path `): loads `machine.json`, validates + `KEY` is a declared contract var (unknown key -> fail loud), sets + `paths[KEY]=VALUE` **preserving every other key**, and writes atomically + (temp + rename), creating `~/.config/dotfiles/` if absent. Idempotent (same + value -> "unchanged"). One Go JSON-merge instead of fragile hand-rolled JSON in + both `setup-linux.sh` and `setup-windows.ps1` (ADR-020). + - **setup-linux.sh**: `dotf env set DOTFILES_REPO_DIR "$CURRENT_DIR"` right + before `dotf env generate` (so the generated path file carries the real + value). **setup-windows.ps1**: same with `$DotfilesDir`. Both inside the + existing `command -v dotf` / `Get-Command dotf` guard. +- **B — defense in depth.** `repoForUpdate()` and the `mem` resolvers prefer a + cascade value only when it is an existing directory, else fall back to + `env.RepoDir()` (walk-up), else (update only) the last-resort literal for a + bare scheduler env. Fixes interactive `dotf update`/`mem` run from inside a + checkout even before/without `machine.json`. +- **Doctor check.** A new `dotf doctor` assertion: `DOTFILES_REPO_DIR` (via the + cascade) resolves to a real checkout (a dir containing `.git`). PASS when it + does; FAIL with an actionable hint (`run setup`, or `dotf env set + DOTFILES_REPO_DIR `) when it resolves to a phantom / missing path — the + SRE health-check that would have caught this class on a fresh box. +- **Guards (incident -> guard).** + - Go unit tests for `dotf env set`: merge preserves other keys, unknown key + fails, idempotent re-set, machine.json created when absent. + - Integration bats (`verify-setup.bats`): after setup, `machine.json` exists, + its `DOTFILES_REPO_DIR` equals the checkout, and `dotf env path + DOTFILES_REPO_DIR` resolves to a real dir. + +## Out of scope + +- **Changing the contract default.** `$HOME/Projects/dotfiles` stays as the + documented last-resort for a bare scheduler env that has neither `machine.json` + nor a discoverable checkout. Seeding `machine.json` makes it irrelevant on a + real machine; removing it would only trade a phantom for an empty string. +- **The other fresh-machine bugs.** #697 (doctor deployed-first vs repo-first), + #691 (GUARD-001 memory-sink on Windows), #690 (dead `injectors.enabled`), #689 + (Windows project-key) are their own issues. This PR only unifies the + `DOTFILES_REPO_DIR` resolution and seeds `machine.json`. +- **Migrating `VAULT_PATH` / other overrides.** `dotf env set` is general (any + contract key), but setup only seeds `DOTFILES_REPO_DIR`; seeding other keys is + left to the user / future work. + +## Risks / open questions + +- **Setup re-writes `DOTFILES_REPO_DIR` on every run** to `$CURRENT_DIR`. This is + intentional and self-healing (setup runs from the authoritative checkout + location); the merge preserves all other keys, and the cascade's env-var tier + still wins for a user who overrides at runtime. +- **Windows `dotf` not yet installed** in some flows: the seed sits inside the + existing `Get-Command dotf` guard, so it is skipped exactly when `env generate` + is, and `profile.ps1` keeps its inline fallback. No regression. +- **`env set` writing under a read-only `$XDG_CONFIG_HOME`**: fails loud with the + write error rather than silently continuing; setup treats it as a warning like + the adjacent `env generate` step. + +## Acceptance criteria + +- [x] `dotf env set ` writes/merges `machine.json`, preserves other + keys, rejects an unknown contract key, and is idempotent. +- [x] setup-linux.sh and setup-windows.ps1 seed `DOTFILES_REPO_DIR` before + `dotf env generate`. +- [x] `repoForUpdate()` and `mem` resolvers fall back to `RepoDir()` walk-up when + the cascade value is not an existing directory. +- [x] `dotf doctor` FAILs (with an actionable hint) when `DOTFILES_REPO_DIR` + resolves to a non-checkout path, PASSes when it resolves to a real one. +- [x] Go unit tests (env set) + integration bats (machine.json seeded) green. +- [x] `go build ./...` and `go test ./...` clean; `bash -n setup-linux.sh`. + +## References + +- GH issue: [#696](https://github.com/mlorentedev/dotfiles/issues/696) +- ADR-025 (cross-machine paths; the cascade this unifies) +- Related fresh-machine cluster: #697, #691, #690, #689 +- Prior art: BUG-026/#694 (setup must not write into the checkout — same + "deploy != checkout" invariant), the existing read-side `dotf env path` diff --git a/specs/BUG-029-seed-machine-repo-dir/tasks.md b/specs/BUG-029-seed-machine-repo-dir/tasks.md new file mode 100644 index 00000000..052a6a94 --- /dev/null +++ b/specs/BUG-029-seed-machine-repo-dir/tasks.md @@ -0,0 +1,28 @@ +--- +id: "BUG-029-seed-machine-repo-dir" +type: spec +status: implementing +created: "2026-07-10" +tags: [spec, tasks] +template_version: "1.0" +--- + +# Tasks — BUG-029-seed-machine-repo-dir + +- [x] T1. `env` package: `SetMachinePath(contractPath, machinePath, key, value)` + — load-or-init machine.json, validate `key` against the contract, merge + preserving other keys, atomic write.
