# This composite action is designed for Gitea Actions runners.
|
||||
# Gitea Actions supports GitHub Actions syntax including $GITHUB_OUTPUT,
|
||||
# actions/cache, and actions/checkout.
|
||||
# This composite action supports both Gitea Actions and GitHub Actions runners.
|
||||
# It detects the VCS host type by checking whether github.api_url is set
|
||||
# (present on GitHub.com and GHES runners, absent on Gitea runners) and uses
|
||||
# the appropriate releases API for version resolution and binary download
|
||||
# (REST API on GitHub, direct URLs on Gitea).
|
||||
#
|
||||
# Security notes:
|
||||
# - On GitHub/GHES (VCS_TYPE=github), inputs.vcs-url is IGNORED to prevent
|
||||
# token exfiltration. API calls use github.api_url; downloads use
|
||||
# github.server_url. Tokens are never sent to user-supplied URLs.
|
||||
# - On Gitea (VCS_TYPE=gitea), inputs.vcs-url is validated (https scheme,
|
||||
# no whitespace/newlines) before use.
|
||||
# - action-repo is validated against owner/repo pattern.
|
||||
# - Tokens are passed via masked environment variables, not step outputs.
|
||||
#
|
||||
# Requirements: python3, sha256sum, curl (all present on ubuntu-* runners).

# Plan: Issue #125 — Rename GITEA_URL → VCS_URL
|
||||
|
||||
## Problem
|
||||
|
||||
The `GITEA_URL` environment variable (and `--gitea-url` flag) implies the binary only works with Gitea.
|
||||
Now that review-bot supports both Gitea and GitHub/GHES, this name is misleading.
|
||||
Renaming to `VCS_URL` makes the binary platform-agnostic in its interface.
|
||||
|
||||
## Constraints
|
||||
|
||||
- Must not break existing users who already use `GITEA_URL` — need a fallback
|
||||
- The CLI flag `--gitea-url` should also be updated to `--vcs-url` for consistency
|
||||
- `INTEGRATION_GITEA_URL` in integration tests is a test-only env var, not the binary's interface; but should be updated for clarity
|
||||
- The action YAML uses `GITEA_URL` as an internal shell variable in bash scripts — distinct from the env var passed to the binary
|
||||
- All changes must compile and pass existing tests
|
||||
|
||||
## Files Affected
|
||||
|
||||
### Binary / Go source
|
||||
| File | Change |
|
||||
|------|--------|
|
||||
| `cmd/review-bot/main.go` | Rename `--gitea-url` → `--vcs-url`, add `VCS_URL` as primary, keep `GITEA_URL` fallback |
|
||||
| `cmd/review-bot/integration_test.go` | Rename `INTEGRATION_GITEA_URL` → `INTEGRATION_VCS_URL` (test-only, no external compat concern) |
|
||||
| `integration_test.go` | Same — rename `INTEGRATION_GITEA_URL` → `INTEGRATION_VCS_URL` |
|
||||
|
||||
### Action YAML
|
||||
| File | Change |
|
||||
|------|--------|
|
||||
| `.gitea/actions/review/action.yml` | Rename input `gitea-url` → `vcs-url`; update env var passed to binary: `VCS_URL` instead of `GITEA_URL`; keep internal bash var as `GITEA_URL` (only used for release download, not passed to binary) |
|
||||
| `.gitea/workflows/ci.yml` | Rename `GITEA_URL` env var to `VCS_URL` in Run review step |
|
||||
|
||||
### Documentation
|
||||
| File | Change |
|
||||
|------|--------|
|
||||
| `README.md` | Update CLI example, env var table entry |
|
||||
|
||||
## Proposed Approach
|
||||
|
||||
### 1. Backward-compatible env var lookup in main.go
|
||||
|
||||
Replace:
|
||||
```go
|
||||
giteaURL := flag.String("gitea-url", envOrDefault("GITEA_URL", ""), "Gitea instance URL")
|
||||
```
|
||||
|
||||
With:
|
||||
```go
|
||||
giteaURL := flag.String("vcs-url", envOrDefaultFallback("VCS_URL", "GITEA_URL", ""), "VCS server URL (e.g. https://gitea.example.com)")
|
||||
```
|
||||
|
||||
Add a helper:
|
||||
```go
|
||||
// envOrDefaultFallback reads primary env var; if empty, falls back to deprecated env var.
|
||||
func envOrDefaultFallback(primary, deprecated, defaultVal string) string {
|
||||
if v := os.Getenv(primary); v != "" {
|
||||
return v
|
||||
}
|
||||
if v := os.Getenv(deprecated); v != "" {
|
||||
slog.Warn("deprecated env var in use; rename to " + primary, "old", deprecated, "new", primary)
|
||||
return v
|
||||
}
|
||||
return defaultVal
|
||||
}
|
||||
```
|
||||
|
||||
**Note:** This must be called AFTER `setupLogger` conceptually, but the flag default is evaluated at flag registration time. Since `setupLogger` runs before `flag.Parse()`, the slog.Warn will print correctly at runtime. We use `log.Printf` as a fallback if this proves problematic.
|
||||
|
||||
Actually — flag defaults are evaluated at registration (line 57), before `setupLogger`. The warning won't go through slog. Two options:
|
||||
- Use `log.Printf` for the deprecation warning (always visible)
|
||||
- Move the fallback lookup to after `flag.Parse()`, checking if the parsed value is still empty
|
||||
|
||||
**Decision:** Move fallback to a post-parse check. This is cleaner:
|
||||
```go
|
||||
vcsURL := flag.String("vcs-url", os.Getenv("VCS_URL"), "VCS server URL")
|
||||
flag.Parse()
|
||||
// Backward compat: fall back to deprecated GITEA_URL
|
||||
if *vcsURL == "" {
|
||||
if v := os.Getenv("GITEA_URL"); v != "" {
|
||||
slog.Warn("GITEA_URL is deprecated; use VCS_URL instead")
|
||||
*vcsURL = v
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
This is clean, idiomatic, and the warning goes through slog correctly.
|
||||
|
||||
### 2. Keep `--gitea-url` as deprecated alias
|
||||
|
||||
Add a hidden flag for backward compat:
|
||||
```go
|
||||
giteaURLAlias := flag.String("gitea-url", "", "Deprecated: use --vcs-url")
|
||||
```
|
||||
|
||||
Post-parse:
|
||||
```go
|
||||
if *vcsURL == "" && *giteaURLAlias != "" {
|
||||
slog.Warn("--gitea-url is deprecated; use --vcs-url instead")
|
||||
*vcsURL = *giteaURLAlias
|
||||
}
|
||||
```
|
||||
|
||||
### 3. Internal variable rename
|
||||
|
||||
Rename `giteaURL` local variable → `vcsURL` throughout `main.go` for consistency.
|
||||
|
||||
### 4. Error message update
|
||||
|
||||
```go
|
||||
fmt.Fprintf(os.Stderr, "Required: --vcs-url, --repo, --pr, --reviewer-token, --llm-model\n")
|
||||
```
|
||||
|
||||
### 5. Action YAML changes
|
||||
|
||||
In `.gitea/actions/review/action.yml`:
|
||||
- Input `gitea-url` → `vcs-url` (with same description, `required: false`, `default: ''`)
|
||||
- Line 172: `GITEA_URL: ${{ inputs.gitea-url || github.server_url }}` → `VCS_URL: ${{ inputs.vcs-url || github.server_url }}`
|
||||
- Lines 115, 140: internal bash vars `GITEA_URL=` are used for downloading binaries — NOT passed to the review-bot binary. Leave them as internal bash vars (they're scope-local in bash). These could be renamed to `SERVER_URL` or `BASE_URL` for local clarity, but renaming them isn't strictly required.
|
||||
|
||||
In `.gitea/workflows/ci.yml`:
|
||||
- Line 52: `GITEA_URL: ${{ github.server_url }}` → `VCS_URL: ${{ github.server_url }}`
|
||||
|
||||
### 6. Integration test updates
|
||||
|
||||
`INTEGRATION_GITEA_URL` → `INTEGRATION_VCS_URL` in both test files.
|
||||
|
||||
### 7. README
|
||||
|
||||
- CLI example: `--gitea-url` → `--vcs-url`
|
||||
- Env var table: `GITEA_URL` → `VCS_URL`, add note about `GITEA_URL` fallback
|
||||
|
||||
## Backward Compatibility Summary
|
||||
|
||||
| Old | New | Fallback? |
|
||||
|-----|-----|-----------|
|
||||
| `GITEA_URL` env var | `VCS_URL` | ✅ with deprecation warning |
|
||||
| `--gitea-url` flag | `--vcs-url` | ✅ with deprecation warning |
|
||||
| `gitea-url` action input | `vcs-url` | ⚠️ No (action version bump handles this) |
|
||||
| `INTEGRATION_GITEA_URL` | `INTEGRATION_VCS_URL` | N/A (test-only) |
|
||||
|
||||
## Error Cases
|
||||
|
||||
- Both `VCS_URL` and `GITEA_URL` set: `VCS_URL` wins (primary takes precedence)
|
||||
- Both `--vcs-url` and `--gitea-url` provided: `--vcs-url` wins
|
||||
- Neither set: existing "missing required flags" error unchanged
|
||||
|
||||
## Edge Cases
|
||||
|
||||
- `os.Getenv` returns "" for unset AND set-to-empty — consistent with existing behavior
|
||||
- The `envOrDefault` helper is unchanged; we add `envOrDefaultFallback` for the one renamed var
|
||||
|
||||
## Testing Strategy
|
||||
|
||||
- Existing unit tests pass unchanged (they don't test env var parsing directly)
|
||||
- Integration tests updated to use new env var name
|
||||
- Manual: `GITEA_URL=https://example.com ./review-bot --repo x --pr 1 ...` should print deprecation warning and proceed
|
||||
- Manual: `VCS_URL=https://example.com ./review-bot ...` should work silently
|
||||
|
||||
## Completion Checklist
|
||||
|
||||
1. `VCS_URL` is read first; `GITEA_URL` is fallback with deprecation warning
|
||||
2. `--vcs-url` flag is primary; `--gitea-url` is deprecated alias with warning
|
||||
3. Error message references `--vcs-url` not `--gitea-url`
|
||||
4. `action.yml` passes `VCS_URL` (not `GITEA_URL`) to the binary
|
||||
5. `ci.yml` passes `VCS_URL` (not `GITEA_URL`) to the binary
|
||||
6. README updated in CLI example and env var table
|
||||
7. Integration tests use `INTEGRATION_VCS_URL`
|
||||
8. `go test ./...` passes
|
||||
9. `go vet ./...` passes
|
||||
10. `go build ./cmd/review-bot` succeeds
|
||||
|
||||
## Open Questions
|
||||
|
||||
- Should the CLI flag `--gitea-url` be completely hidden from `--help` or just deprecated with a note? The issue doesn't specify. Decision: keep it visible but add "(deprecated: use --vcs-url)" to the description.
|
||||
- Should action.yml also add `gitea-url` as a deprecated input alias? The issue says "Update the action to pass the new env var name" — no mention of backward compat for the action input. Decision: rename only, no alias (action users pin a version anyway).
|
||||
- The bash-internal `GITEA_URL` variable in action.yml scripts (used for release download, not passed to binary) — rename for clarity? Decision: yes, rename to `BASE_URL` to avoid confusion with the env var.
