From 91bce1dbd5171e853bcc33c4e99e679501d776b0 Mon Sep 17 00:00:00 2001 From: Jacob Magar Date: Fri, 13 Mar 2026 23:19:50 -0400 Subject: [PATCH] fix: address PR review threads (test-actions, diagnostics, docker, health, storage, plugin) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Resolves review threads: - PRRT_kwDOO6Hdxs50R8VI (test-actions.sh: remove || echo "000" curl fallback) - PRRT_kwDOO6Hdxs50R8VJ (test-actions.sh: JSON parse failures → FAIL not silent) - PRRT_kwDOO6Hdxs50QdKd (diagnostics.py: sanitize raw exception text from ToolError) - PRRT_kwDOO6Hdxs50QdKs (storage.py: unassigned uses unassignedDevices query) - PRRT_kwDOO6Hdxs50Mwlk (docker.py: port_conflicts returns flat merged list) - PRRT_kwDOO6Hdxs50Mwlo (docker.py: logs returns plain string not dict) - PRRT_kwDOO6Hdxs50Mt5K (docker.py: unraid_docker logs format compatibility) - PRRT_kwDOO6Hdxs50Mt5L (health.py: or {} null guards throughout) - PRRT_kwDOO6Hdxs50Mt5r (docker.py: port_conflicts flat list backward compat) - plugin.json: version synced to 0.4.4 to match pyproject.toml Changes: - test-actions.sh: curl exit code captured directly; JSON failures surface as FAIL - diagnostics.py: 4 ToolError sites log exc_info=True, raise sanitized messages - storage.py: unassigned action queries unassignedDevices instead of disks - docker.py: logs action returns newline-joined string; port_conflicts merges containerPorts + lanPorts into a flat list for backward compatibility - health.py: all nested dict lookups use `or {}` instead of `.get(k, {})` to handle explicit GraphQL null values Co-authored-by: Claude --- .claude-plugin/plugin.json | 2 +- tests/mcporter/test-actions.sh | 150 +++++++++++++----------- unraid_mcp/subscriptions/diagnostics.py | 25 +++- unraid_mcp/tools/docker.py | 28 ++++- unraid_mcp/tools/health.py | 14 +-- unraid_mcp/tools/storage.py | 4 +- 6 files changed, 133 insertions(+), 90 deletions(-) diff --git a/.claude-plugin/plugin.json b/.claude-plugin/plugin.json index ec57e67..11b4243 100644 --- a/.claude-plugin/plugin.json +++ b/.claude-plugin/plugin.json @@ -1,7 +1,7 @@ { "name": "unraid", "description": "Query and monitor Unraid servers via GraphQL API - array status, disk health, containers, VMs, system monitoring", - "version": "0.4.0", + "version": "0.4.4", "author": { "name": "jmagar", "email": "jmagar@users.noreply.github.com" diff --git a/tests/mcporter/test-actions.sh b/tests/mcporter/test-actions.sh index 0edc5fb..26a287d 100755 --- a/tests/mcporter/test-actions.sh +++ b/tests/mcporter/test-actions.sh @@ -89,6 +89,31 @@ run_test_capture() { echo "$output" # pure JSON → captured by caller's $() } +extract_id() { + # Extract an ID from JSON output using a Python snippet. + # Usage: ID=$(extract_id "$JSON_OUTPUT" "$LABEL" 'python expression') + # If JSON parsing fails (malformed mcporter output), record a FAIL. + # If parsing succeeds but finds no items, return empty (caller skips). + local json_input="$1" label="$2" py_code="$3" + local result="" py_exit=0 parse_err="" + # Capture stdout (the extracted ID) and stderr (any parse errors) separately. + # A temp file is needed because $() can only capture one stream. + local errfile + errfile=$(mktemp) + result=$(echo "$json_input" | python3 -c "$py_code" 2>"$errfile") || py_exit=$? + parse_err=$(<"$errfile") + rm -f "$errfile" + if [[ $py_exit -ne 0 ]]; then + printf " %-60s${RED}FAIL${NC} (JSON parse error)\n" "$label" >&2 + [[ -n "$parse_err" ]] && echo "$parse_err" | head -2 | sed 's/^/ /' >&2 + ((FAIL++)) || true + FAILED_TESTS+=("$label (JSON parse)") + echo "" + return 1 + fi + echo "$result" +} + skip_test() { local label="$1" reason="$2" printf " %-60s${YELLOW}SKIP${NC} (%s)\n" "$label" "$reason" @@ -109,9 +134,12 @@ echo "" printf "Checking connectivity...
