build: update golangci-lint to v2.12.2 with org-standard v2 config (#96)
check / check (push) Successful in 4s
Updates golangci-lint to v2.12.2 and sets `.golangci.yml` to the org-standard v2-schema config already deployed across the org's repos. The config change is owner-authorized (see #96 (comment) and #96 (comment)); the same file is being landed as canonical via prompts PR #24 (sneak/prompts#24). ## Changes - **Commit-pinned installs**: golangci-lint pinned to commit `c0d3ddc9cf3faa61a4e378e879ece580256d76e5` (v2.12.2, released 2026-05-06) in `Dockerfile` and `script/bootstrap`. - **`.golangci.yml` set to the org-standard v2 config** (sha256 `021cc83f4e6fc7c31b95b34b846723dfcf20b66b7baeea1dc40406e643346bcb`), byte-identical to the file used across the org's other repos. Settings live under `linters.settings`, so the `lll`/`funlen`/`cyclop`/`dupl` thresholds are actually applied (under the old hybrid file, v2 silently ignored the top-level `linters-settings` block). - **Lint fixes** required by the now-active thresholds: - `goconst`: shared constants for repeated status/priority/DNS-fixture strings in `internal/watcher/watcher.go` and the notify, state, and watcher tests - `dupl`: consolidated duplicated ntfy/slack HTTP-error tests and SendNotification endpoint-error tests behind shared helpers in `internal/notify/delivery_test.go` - `lll`: wrapped long test table entries and comments in `internal/config/classify_test.go`, `internal/notify/history_test.go`, `internal/state/state_test.go`, `internal/watcher/watcher_test.go`; shortened one inline nolint justification in `internal/notify/retry.go` - **`TODO.md`**: Completed Steps entry updated in the same commit. - Rebased onto current `main` (`f79cd98`); the branch is one clean commit. ## Notes - v2.12 deprecates the `gomodguard` linter in favor of `gomodguard_v2`. The org-standard config does not disable the deprecated linter, so golangci-lint may emit an informational deprecation warning; this is accepted by the owner and does not affect the exit status (this exact config+code combination was CI-green at `dea7e44`). ## Verification - `make check` exits 0 (fmt-check, tests, lint) - `make lint`: 0 issues; no deprecation warning surfaced in the runs performed - sha256 of `.golangci.yml` at HEAD verified equal to `021cc83f4e6fc7c31b95b34b846723dfcf20b66b7baeea1dc40406e643346bcb` Co-authored-by: sneak <sneak@sneak.berlin> Reviewed-on: #96 Co-authored-by: clawbot <clawbot@noreply.example.org> Co-committed-by: clawbot <clawbot@noreply.example.org> |

feat: add retry with exponential backoff for notification delivery (#87)
check / check (push) Successful in 37s
## Summary Notifications were fire-and-forget: if Slack, Mattermost, or ntfy was temporarily down, changes were silently lost. This adds automatic retry with exponential backoff and jitter to all notification endpoints. ## Changes ### New file: `internal/notify/retry.go` - `RetryConfig` struct with configurable max retries, base delay, max delay - `backoff()` computes delay as `BaseDelay * 2^attempt`, capped at `MaxDelay`, with ±25% jitter - `deliverWithRetry()` wraps any send function with the retry loop - Defaults: 3 retries (4 total attempts), 1s base delay, 10s max delay - Context-aware: respects cancellation during retry sleep - Injectable `sleepFn` for test determinism ### Modified: `internal/notify/notify.go` - Added `retryConfig` and `sleepFn` fields to `Service` - Updated `dispatchNtfy`, `dispatchSlack`, `dispatchMattermost` to wrap sends in `deliverWithRetry` - Structured logging: warns on each retry, logs error only after all retries exhausted, logs info on success after retry ### Modified: `internal/notify/export_test.go` - Added test helpers: `SetRetryConfig`, `SetSleepFunc`, `DeliverWithRetry`, `BackoffDuration` ### New file: `internal/notify/retry_test.go` - Backoff calculation tests (exponential increase, max cap with jitter) - `deliverWithRetry` unit tests: first-attempt success, transient failure recovery, exhausted retries, context cancellation - Integration tests via `SendNotification`: transient failure retries, all-endpoints retry independently, permanent failure exhausts retries ## Verification - `make fmt` ✅ - `make check` (format + lint + tests + build) ✅ - `docker build .` ✅ - All existing tests continue to pass unchanged - No DNS client mocking — notification tests use `httptest` servers closes #62 Co-authored-by: clawbot <clawbot@noreply.git.eeqj.de> Reviewed-on: #87 Co-authored-by: clawbot <clawbot@noreply.example.org> Co-committed-by: clawbot <clawbot@noreply.example.org> |
