From 76a9e95e5de96a0e68536569bfc2922d9dd62995 Mon Sep 17 00:00:00 2001 From: Diego Gerardo Barajas Suarez Date: Mon, 3 Aug 2026 08:33:01 -0500 Subject: [PATCH 01/14] =?UTF-8?q?feat(python):=20ergonomics=20features=20?= =?UTF-8?q?=E2=80=94=20errors,=20retry,=20pagination=20(TASK-013..018=20+?= =?UTF-8?q?=20046..049)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Feature D (errors): MercadoPagoError base + 11 typed subtypes (MP*Error). MPResponse(dict) wrapper with raise_for_status(), is_success, error_message. build_error() factory maps HTTP status codes to subtypes. Authorization header not stored in responses (CWE-209 compliant by design — Python MPResponse holds only response body, never request headers). Feature E (delta): MPPaymentError/MPValidationError/MPResourceLockedError/MPDependencyError (TASK-046). MPOrderErrors/MPPaymentErrors error string constants (TASK-046). PaymentStatus/OrderStatus/PreapprovalStatus/MerchantOrderStatus/RefundStatus enums (TASK-047). DeprecationWarning for notification_url in payment.create() and preference.create() (TASK-047). x-idempotency-key 1-64 chars validation (TASK-047). Webhook docstring (TASK-047). config/defaults.py module with DEFAULT_TIMEOUT_SECONDS=60.0, DEFAULT_MAX_RETRIES=3 (TASK-049). initial_delay=None fix in RequestOptions (TASK-049). Feature B (retry): RequestOptions gains initial_delay, max_delay, jitter, retry_on, on_retry. Per-request retry_on propagated to urllib3.Retry in HttpClient. Silent JSON parse failure now raises MPServerError instead of silent None (TASK-013). Feature A (pagination): search_auto_paging_iter() lazy generator in pagination/iterator.py. Added to 7 resources: payment, customer, order, preference, merchant_order, preapproval, plan. 72 unit tests passing. 16 webhook tests unchanged.
