charset=UTF-8 Content-Transfer-Encoding: 8bit Adds resilient retry logic to the Evolution Go API client. Transient HTTP errors (5xx, URLError, socket.timeout) now retry up to 3 times with exponential backoff + jitter; HTTP 4xx errors raise immediately (no retry, deterministic client errors). ## Changes **`.claude/skills/int-evolution-go/scripts/evolution_go_client.py`:** - New helper `_retry_http_call_client(do_call, max_attempts=3, base_delay=2.0, max_delay=8.0)` — generic retry wrapper with exponential backoff + jitter. Logs structured JSON events (`api_request_retry` / `api_request_failed`). - Refactor `api_request` to wrap the actual HTTP call in `_do_call` and delegate to the retry helper. Removes inline try/except/sys.exit so library callers can handle errors; the CLI `main()` catches and exits as before. - Refactor `main()` to wrap handler invocation in try/except for `urllib.error.HTTPError` / `URLError` / `socket.timeout` — preserves the exact CLI exit-1-on-failure behavior while letting library users propagate. **`tests/whatsapp/test_retry_backoff.py` (new):** 4 synthetic tests covering: 1. HTTP 500 x3 → retries then raises (TestApiRequestRetry) 2. HTTP 400 → raises immediately, no retry 3. URLError x3 → retries then raises 4. Success on third attempt → returns result, call_count=3 All 4 tests pass against the modified `api_request`. ## Worst-case latency 3 attempts with all 5xx: sleep ≤ 2^0 + 0.5 + 2^1 + 0.5 = 5.5s total (capped at max_delay=8s per attempt).

Dois pontos no triggers.py: a) `webhook_receiver` (~linha 389): mesma correção do PR #78 — só absorve o erro se a mensagem do driver menciona `uq_trigger_idem` ou `idempotency_key` E `idem_key` está set; caso contrário loga com contexto completo e re-raise. b) Endpoint `/triggers/executions//replay` (~linha 476): cria nova execution reusando `ex.idempotency_key`. Tinha o mesmo catch genérico, mascarando outros IntegrityError como "idempotent_skip". Aplicada a mesma proteção usando `ex.idempotency_key` no check. (Sourcery não citou este segundo ponto, mas é o mesmo bug — corrigido por simetria.) 2. `_classify_error` — tighten typing - Define alias `ErrorCategory = Literal["transient", "permanent"]`. - Atualiza return type pra refletir o que a função realmente retorna. - Atualiza comentário em `TriggerExecution.error_category` (models.py) que listava 4 categorias (validation/unknown) que nunca eram emitidas pelo classificador — consumidores não vão mais depender de valores inexistentes. 3. `trigger_stats` — parametriza SQL - `datetime('now', '-{days} days')` interpolado vira `:cutoff` bindado (cutoff calculado em Python com `timedelta`). - `WHERE trigger_id IN ({id_list})` vira `IN :wpp_ids` com `bindparam("wpp_ids", expanding=True)` — SQLAlchemy expande pra `(:id_1, :id_2, ...)` e binda cada valor. - Inputs hoje são "seguros" (ints + days constrained), mas parametrizar é mais robusto contra regressões e mais legível. 4. `confirmReplay` (Triggers.tsx) — error handling estruturado - Cria `ApiError` em `lib/api.ts` carregando `status` (número HTTP) e `code` (string do JSON do backend, ex.: `rate_limited`). - `buildError` agora retorna `ApiError` em vez de `Error` simples. - `Triggers.tsx::confirmReplay` checa `e instanceof ApiError && (e.status === 429 || e.code === 'rate_limited')` em vez de `msg.includes('429')`. Mais resiliente a mudanças no formato da mensagem (ex.: tradução, prefixo). - `.message` preservado no mesmo formato (`" : "`) pra não quebrar os 3 outros call sites que usam `msg.includes(...)` (Backups.tsx, StepBrainConnect.tsx, RestoreSelectRepo.tsx) — migração desses fica pra um PR dedicado. Sintaxe Python validada com `python3 -m py_compile`. Typecheck do frontend deixado pro CI do PR (deps não instaladas localmente). --- dashboard/backend/models.py | 2 +- dashboard/backend/routes/triggers.py | 100 ++++++++++++++++------ dashboard/frontend/src/lib/api.ts | 28 +++++- dashboard/frontend/src/pages/Triggers.tsx | 10 ++- 4 files changed, 107 insertions(+), 33 deletions(-) diff --git a/dashboard/backend/models.py b/dashboard/backend/models.py index 2dcff6f1..c2ee0fc6 100644 --- a/dashboard/backend/models.py +++ b/dashboard/backend/models.py @@ -342,7 +342,7 @@ class TriggerExecution(db.Model): # WhatsApp retry pattern (PR-1: migration 2026-05-11) # rollback: DROP indices uq_trigger_idem + ix_trigger_executions_idem_key; columns are nullable, ignored by old code idempotency_key = db.Column(db.String(255), nullable=True, index=True) # messageId WPP or other source dedup key - error_category = db.Column(db.String(20), nullable=True) # transient | permanent | validation | unknown + error_category = db.Column(db.String(20), nullable=True) # transient | permanent (ver _classify_error em routes/triggers.py) last_replay_at = db.Column(db.DateTime, nullable=True) # rate-limit: 60s between replays of the same execution @property diff --git a/dashboard/backend/routes/triggers.py b/dashboard/backend/routes/triggers.py index 1c550529..5e3e8b7b 100644 --- a/dashboard/backend/routes/triggers.py +++ b/dashboard/backend/routes/triggers.py @@ -11,8 +11,10 @@ import threading import time from pathlib import Path -from datetime import datetime, timezone +from datetime import datetime, timedelta, timezone +from typing import Literal from flask import Blueprint, jsonify, request, current_app +from sqlalchemy import bindparam from flask_login import current_user from models import db, Trigger, TriggerExecution, has_permission, audit from sqlalchemy.exc import IntegrityError @@ -42,11 +44,21 @@ ) -def _classify_error(err_msg: str, exc: Exception | None = None) -> str: - """Return 'transient' or 'permanent' based on the exception and error text. +ErrorCategory = Literal["transient", "permanent"] + + +def _classify_error(err_msg: str, exc: Exception | None = None) -> ErrorCategory: + """Classify a failed execution as transient or permanent. transient → worth retrying (HTTP 5xx, network, timeout) permanent → deterministic failure, replay only on operator decision + + NOTE: o comentário em `TriggerExecution.error_category` (models.py) + historicamente listava 4 valores ("transient | permanent | validation + | unknown").
