## Summary - When an invalid `--ads` value is explicitly provided (e.g. `--ads=my-directory-name`), the bot now exits with code 2 and a clear error message listing valid options, instead of silently falling back to the command default - Fixes the numeric ID regex from unanchored `\d+[,\d+]*` (which could match partial strings like `abc123`) to anchored `^\d+(,\d+)*$` - Adds `_is_valid_ads_selector()` helper to deduplicate validation logic across publish/update/download/extend commands ## Motivation When calling `kleinanzeigen-bot publish --ads=led-grow-light-set` (passing a directory name instead of a numeric ad ID), the bot silently fell back to `--ads=due` and republished all due ads — causing unintended republication of multiple ads and loss of conversations on those ads. The silent fallback with only a WARNING log message makes it too easy to accidentally trigger unwanted operations. An explicit error with exit code 2 (consistent with other argument validation like `--workspace-mode`) is the expected behavior for invalid arguments. ## Changes | File | Change | |------|--------| | `src/kleinanzeigen_bot/__init__.py` | Added `_ads_selector_explicit` flag (set when `--ads` or `--force` is used), `_is_valid_ads_selector()` helper method, and updated all 4 command blocks (publish/update/download/extend) to error on explicitly invalid selectors | | `resources/translations.de.yaml` | Replaced 3 old fallback messages with 4 new error messages | | `tests/unit/test_init.py` | Updated 2 existing tests to expect `SystemExit(2)` instead of silent fallback, added 2 new tests for update/extend invalid selectors | ## Test plan - [x] All 754 unit tests pass (`pdm run utest`) - [x] Lint clean (`pdm run lint`) - [x] Translation completeness verified (`test_all_log_messages_have_translations`, `test_no_obsolete_translations`) - [x] `--ads=invalid` on publish/update/download/extend all exit with code 2 - [x] Default behavior (no `--ads` flag) unchanged for all commands - [x] Valid selectors (`--ads=all`, `--ads=due`, `--ads=12345,67890`, `--ads=changed,due`) still work <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Bug Fixes** * Stricter validation of ad selectors; invalid selectors now terminate with exit code 2 and preserve safe defaults when no selector is provided. * **New Features** * Support for comma-separated numeric ID lists as a valid selector format. * **Tests** * Unit tests updated to assert non-zero exit on invalid selectors and verify default-fallback behavior. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Co-authored-by: Liermann Torsten - Hays <liermann.hays@partner.akdb.de> Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>
