## What happened The [Tag and Release run](https://github.com/coder/coder/actions/runs/28549109434/job/84641825784) failed in the `prepare-release` job at the step "Prepare release (calculate version, create tag and branch)" with: ``` error: create tag v2.35.0-rc.0: exit status 128 ``` ## Root cause `prepare-release` creates an **annotated** tag via `git tag -a` (`scripts/release-action/prepare.go`), which records a tagger and therefore requires a git identity. The job never ran `git config user.name/user.email`, and runners have none configured, so git aborts with exit status 128. The real `fatal:` message was hidden because `realExecutor.RunMutation` discarded the command's stderr. ## Changes - **`.github/workflows/tag-and-release.yaml`**: add a "Configure git identity" step (`ci@coder.com` / `Coder CI`) to the `prepare-release` job, before the release tool runs. This matches the identity pattern already used later in the same workflow. - **`scripts/release-action/cmdexec.go`**: capture stderr in `RunMutation` and include it in the returned error, so a failing mutation surfaces the underlying command output (e.g. git's `fatal:` line) instead of only `exit status N`. - **`scripts/release-action/cmdexec_test.go`**: add a test asserting stderr is surfaced on failure. ## Testing - `go test ./scripts/release-action/...` passes. - `go vet ./scripts/release-action/...` and `gofmt` clean. - `actionlint .github/workflows/tag-and-release.yaml` clean. - Reproduced the failure locally: `git tag -a` with no usable identity exits 128 (`fatal: no email was given and auto-detection is disabled`); with an identity configured it succeeds. <details> <summary>Root-cause analysis / decision log</summary> **Failing step** runs `go run ./scripts/release-action prepare-release --type create-release-branch --ref main --commit cb1a87b…`. 1. The tool computes the next version `v2.35.0-rc.0` and calls `createAndPushTag`, which runs `git tag -a v2.35.0-rc.0 -m "Release v2.35.0-rc.0" <targetRef>` (`prepare.go:56`). 2. That git command exits **128**, wrapped as `error: create tag v2.35.0-rc.0: exit status 128`. **Why it's the identity, and not something else:** - No `git config user.name/user.email` step exists in the `prepare-release` job; the `setup-mise` action does not set it; and the tool itself never sets an identity. Annotated tags require a tagger, so `git tag -a` fails on runners whose auto-detected identity is bogus (`…@runner.(none)`), which is rejected under git's strict identity check. - Not a pre-existing tag collision: no `v2.35.0*` tag exists on the remote, and the code pre-checks for an existing tag (and would emit a different "already exists" error). - Not an unresolved ref: `targetRef` resolves to the provided commit SHA, checked out at `fetch-depth: 0`. - The log was unhelpful because `RunMutation` used `cmd.Run()` without wiring git's stderr (`cmdexec.go`), discarding the `fatal:` line and leaving only `exit status 128`. This PR fixes that too. - The sibling `release.yaml` explicitly sets `git config user.email/user.name` before its git mutations; that step was simply missing from the newer `tag-and-release.yaml` `prepare-release` job. </details> --- > Generated by Coder Agents on behalf of @f0ssel.
