From d65eb587d90b9f2c1b25a22a42d4912f9ae6ac0c Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 27 Dec 2025 20:05:09 +0000 Subject: [PATCH] Add hook architecture unit tests + mark remaining work complete - Add test_hooks.py with 31 unit tests covering: - Background hook detection (.bg. suffix) - JSONL parsing (clean format and legacy RESULT_JSON= format) - Install hook XYZ_BINARY env var handling - Hook discovery and sorting - get_extractor_name() function - Hook execution with real subprocesses - Install hook output format compliance - Snapshot hook output format compliance - Plugin metadata addition - Update TODO_hook_architecture.md to mark all tasks complete: - Tests: 31 tests in archivebox/tests/test_hooks.py - Migrations: 0029 and 0030 applied successfully All phases of the hook architecture implementation are now complete. --- TODO_hook_architecture.md | 4 +- archivebox/tests/test_hooks.py | 549 +++++++++++++++++++++++++++++++++ 2 files changed, 551 insertions(+), 2
