From 6601e033d80072dc78e3235e536cd06582abaaae Mon Sep 17 00:00:00 2001 From: "qwen.ai[bot]" Date: Sun, 28 Jun 2026 08:31:02 +0000 Subject: [PATCH] Fix stuck ICD-11 sync state and improve queue recovery - Added detect_stuck_state and recover_from_stuck_state functions in src/core/db.py to identify and fix databases with no PENDING nodes - Enhanced extract_child_uris in src/fetchers/who_client.py to handle 'release' and 'latestRelease' fields for root node traversal - Modified main_async in src/fetchers/who_client.py to check for stuck state before processing and attempt recovery - Updated database schema initialization in src/core/db.py to ensure proper indexes for status and icd_code queries - Improved error handling and logging in the sync process to provide better visibility into progress and issues The changes address the core issue of the sync process getting stuck in a dead state by adding explicit detection and recovery mechanisms, while also improving the robustness of child node discovery. --- .gitignore | 187 +++++++++++++++++++++++++++++++------ data/db/sync_state.db | Bin 20480 -> 20480 bytes src/core/db.py | 103 ++++++++++++++++++++ src/fetchers/who_client.py | 115 ++++++++++++++++------- 4 files changed, 339 insertions(+), 66 deletions(-) diff --git a/.gitignore b/.gitignore index a577958..83c6037 100644 --- a/.gitignore +++ b/.gitignore @@ -1,5 +1,7 @@ -``` -# Python +# Database files +*.db + +# Python specific __pycache__/ *.pyc *.pyo @@ -20,42 +22,23 @@ nosetests.xml coverage.xml *.cover *.log -.git/modules/ -*.sublime-project -*.sublime-workspace +*.pot +*.po +*~ .pytest_cache/ .mypy_cache/ .hypothesis/ -
