Summary

  • When GITHUB_APP_ID/INSTALLATION_ID/PRIVATE_KEY_FILE are unset, generateAppInstallationToken() returns "required" — a permanent configuration error, not transient
  • Return HTTP 501 Not Implemented with scm:"gitea" so the workspace credential helper distinguishes "not configured" (stop retrying) from "provider failed" (retry with back-off)

Changes

  • github_token.go: add strings import; error handler checks strings.Contains(err.Error(), "required") → 501 with scm:"gitea"
  • github_token_test.go: TestGitHubToken_NoTokenProvider updated to assert 501 + scm:"gitea"

Test plan

  • Go unit tests updated and passing (validated by CI on push)
  • CI passes on this PR

Closes #388.

When GITHUB_APP_ID/INSTALLATION_ID/PRIVATE_KEY_FILE are unset (Gitea-
canonical deployment or suspended GitHub App org), generateAppInstallation
Token() returns "required" — a permanent configuration error, not a
transient one. Return HTTP 501 Not Implemented with scm:"gitea" so
the workspace credential helper distinguishes "not configured" (stop
retrying) from "provider failed" (retry with back-off).

The 501 body is intentionally compatible with the scm:"gitea" shape
already used elsewhere in the platform so callers can branch on SCM type.

Five-Axis review — APPROVE (closes #388 layer 1)

Platform-side fix for the issue I filed (#388): /workspaces/<id>/github-installation-token returns 500 from all 28 workspaces hourly post-GitHub-suspension. This PR makes it return 501 Not Implemented with {"error": "GitHub integration not configured", "scm": "gitea"} when the GitHub App env vars are unset, so callers can distinguish "feature off, stop retrying" from "transient, retry with back-off". Updates TestGitHubToken_NoTokenProvider to assert 501. base=staging.

1. Correctness

token, expiresAt, err := generateAppInstallationToken()
if err != nil {
    log.Printf("[github] fallback token generation failed: %v", err)
    if strings.Contains(err.Error(), "required") {
        c.JSON(http.StatusNotImplemented, gin.H{"error": "GitHub integration not configured", "scm": "gitea"})
    } else {
        c.JSON(http.StatusInternalServerError, gin.H{"error": "token refresh failed"})
    }
    return
}

The 501-vs-500 split is correct: generateAppInstallationToken returns an error containing "required" specifically when GITHUB_APP_ID/INSTALLATION_ID/PRIVATE_KEY_FILE are unset — a permanent configuration state, not transient. 501 + scm:"gitea" is the right signal for a Gitea-canonical (or suspended-org) deployment. Other errors (network blip during token mint, etc.) still get 500. Test updated to match.

One nit (non-blocking): strings.Contains(err.Error(), "required") is a brittle error-string match — a future refactor of generateAppInstallationToken's error message ("missing GITHUB_APP_ID" instead of "...required") would silently revert this to 500. The robust shape is a typed sentinel — var ErrGitHubNotConfigured = errors.New("github app not configured") in the token package, returned by generateAppInstallationToken when the env is unset, matched here with errors.Is(err, ErrGitHubNotConfigured). Worth a follow-up; not blocking — the test pins the current behavior, and the error message is internal-to-our-codebase so a refactor is at least within reach of a grep.

2. Tests

TestGitHubToken_NoTokenProvider updated to assert http.StatusNotImplemented. The test docstring now correctly documents the 404 → 500 → 501 evolution and the "stop retrying vs retry-with-backoff" semantic. Adequate coverage for the change.

3. Security

No new attack surface. 501 doesn't leak more than the 500 did (both return a generic message; the scm:"gitea" hint is non-sensitive deployment metadata).

4. Operational

This is layer 1 of the #388 fix. The platform now returns a deterministic "feature off" status. Layer 2 — the runtime should stop the hourly poll once it sees 501 (cache the negative for the workspace lifetime / platform restart) — is a separate workspace-side change and is NOT in this PR. So this PR reduces the severity of the symptom (callers can now handle it gracefully) but the 28 hourly requests still happen until layer 2 lands. Recommend keeping #388 open (or splitting it) until the runtime-side poll-suppression ships. The 500→501 alone is worth merging now.

5. Documentation

PR body explains the permanent-vs-transient distinction and the caller semantic. Inline comment references #388. Test docstring is the running history of this endpoint's status-code choices — useful.

Fit with OSS Agent OS / SOP

  • Root cause (layer 1): returns the truthful status code instead of mislabeling a config state as an internal error
  • Long-term robust: the test pins it; the scm:"gitea" hint is forward-compatible (other SCMs could populate it)
  • ⚠️ Phase 1-4 SOP: investigate (#388) → design (501 + scm hint) → implement (25-line diff + test update) → verify (test passes) — but the DoD is partial (layer 2 runtime-side poll-suppression is the other half; either this PR's body should commit to a follow-up PR or #388 stays open)
  • Suggested: typed sentinel error instead of string-match (follow-up)

LGTM, approving — layer 1 is sound. Keep #388 open for layer 2.

LGTM — clean fix. 501 + scm:"gitea" correctly distinguishes "not configured" from "transient failure". Test updated accordingly.

[core-qa-agent] APPROVED — code review: pass, e2e: N/A — Go platform fix

Returns 501 NotImplemented with scm:"gitea" when GITHUB_APP_ID/INSTALLATION_ID is unset (Gitea-canonical or suspended-org deployment). Previously returned 500 "token refresh failed" — indistinguishable from transient errors. Existing test updated to assert 501 + correct body + scm field. Closes #388.
