From 45e9749d37079529263438ed9688db59776662a8 Mon Sep 17 00:00:00 2001 From: Marcin Zieba Date: Tue, 28 Apr 2026 11:58:42 +0200 Subject: [PATCH 01/64] fix: update module type scalar properties (e.g. part_number) on --update - Extend the module_type_list GraphQL query to fetch part_number, description, comments, weight and weight_unit so existing values can be compared against the YAML - Add MODULE_TYPE_PROPERTIES constant listing those updatable fields - filter_actionable_module_types now flags module types with changed scalar properties as actionable (not only missing images/components) - _process_single_module_type applies a PATCH update for any differing properties when not in only_new mode, and increments a new module_updated counter - Expose module_updated counter in the summary log output - Add tests covering the new changed/unchanged/only_new property paths --- core/graphql_client.py | 5 ++ core/netbox_api.py | 48 ++++++++++++ nb-dt-import.py | 1 + tests/test_netbox_api.py

Zieba Date: Tue, 28 Apr 2026 13:27:04 +0200 Subject: [PATCH 02/64] fix: module change detection and diff-u report without --update - Always run full module change detection (property comparison) even without --update, mirroring device type behaviour. Previously filter_actionable_module_types short-circuited to only-new when --update was absent, so modified properties were never detected. - MODULE TYPE CHANGE DETECTION block is now always shown (new / unchanged / modified counts), with a hint to use --update when modified modules are found. - Verbose diff output for modified module types now uses the same diff-u format as device types: ~ manufacturer/model Properties: - part_number: + part_number: Changes are grouped per module and emitted after the detection loop under a MODIFIED MODULE TYPES header. - Repo update log now includes the branch name: 'Updated repo from (branch: )' - 503 / RequestError from NetBox (e.g. proxy blocking the request) now shows the endpoint URL, HTTP status, and the raw response body so the source of the error (proxy vs NetBox) is immediately visible. --- core/netbox_api.py | 54 +++++++++++++++++++++++++++++++++++++++++----- core/repo.py | 2 +- nb-dt-import.py | 18 +++++++++------- 3 files changed, 60 insertions(+), 14 deletions(-) diff --git a/core/netbox_api.py b/core/netbox_api.py index 22498d05..a3637b47 100644 --- a/core/netbox_api.py +++ b/core/netbox_api.py @@ -212,6 +212,17 @@ def verify_compatibility(self): f"Connection error while connecting to NetBox at {self.url}: {e}\n" f"Hint: Verify that NetBox is running and reachable at {self.url}." ) + except pynetbox.core.query.RequestError as e: + endpoint = getattr(e, "base", self.url) + status = getattr(e.req, "status_code", "?") if hasattr(e, "req") else "?" + reason = getattr(e.req, "reason", "") if hasattr(e, "req") else "" + body = (getattr(e, "error", "") or "").strip()[:500] + details = f"HTTP {status} {reason}".strip() + msg = f"NetBox returned an error connecting to {endpoint} ({details})." + if body: + msg += f"\nResponse body (may be from an intermediate proxy):\n{body}" + msg += f"\nHint: Verify that {self.url} is reachable and not blocked by a proxy." + system_exit(msg) _raw = [int(re.sub(r"\D.*", "", x.strip()) or "0") for x in nb_version.split(".")] version_split = (_raw + [0, 0])[:2] # pad to (major, minor) to guard against single-component strings @@ -686,6 +697,25 @@ def filter_new_module_types(module_types, all_module_types): new_module_types.append(module_type) return new_module_types + def _log_module_property_diffs(self, mfr_slug, model, fields_info): + """Emit diff-u style lines for changed module type properties. + + Args: + mfr_slug (str): Manufacturer slug. + model (str): Module type model name. + fields_info (list[tuple]): List of ``(field, old_val, new_val)`` tuples. + """ + self.handle.verbose_log(f" ~ {mfr_slug}/{model}") + self.handle.verbose_log(" Properties:") + pad = min(max(len(field) for field, _, _ in fields_info), 30) + for field, old_val, new_val in fields_info: + name = f"{field}:{'':{max(0, pad -

Fix false-positive _mappings diff for module type front-ports preload_module_type_components() stored raw pynetbox REST records in the cache without wrapping them with _FrontPortRecordWithMappings, so _compare_component_properties() saw no _mappings_canonical and always produced frozenset() on the NetBox side — causing every front-port with a rear-port mapping to appear changed on every run. Fix: wrap front_port_template items during preload, mirroring what _build_component_cache() does for device type GraphQL records. 2. Fix spurious 'Image already exists, skipping' log during detection-only runs _upload_module_type_images() was called before the 'only_new and not is_new' early-return guard in _process_single_module_type(), so every non-update run emitted image-skip log lines for all existing module types that happened to have images. Fix: move the early-return guard above the image upload call. 3. Parallelize module type component REST preloading preload_module_type_components() fetched all component types sequentially (~70 REST calls for a typical library), while device type preloading uses a ThreadPoolExecutor. Fix: dispatch each component type into a thread pool so all REST calls run concurrently, matching the device type preloading approach. --- core/netbox_api.py | 30 +++++++++++++++++++++--------- 1 file changed, 21 insertions(+), 9 deletions(-) diff --git a/core/netbox_api.py b/core/netbox_api.py index 9b9774a4..a9e5c9c6 100644 --- a/core/netbox_api.py +++ b/core/netbox_api.py @@ -970,13 +970,12 @@ def _process_single_module_type(self, curr_mt, src_file, all_module_types, modul ) return False - # Module type was just created — upload images now that the object exists - # and its id can be used as the attachment target. - self._upload_module_type_images(module_type_res, src_file, module_type_existing_images) - if only_new and not is_new: return True + # Upload images for both cached and newly created module types + self._upload_module_type_images(module_type_res, src_file, module_type_existing_images) + # Module component keys often use hyphens in YAML if "interfaces" in curr_mt: self.device_types.create_module_interfaces(curr_mt["interfaces"], module_type_res.id, context=src_file) @@ -1898,7 +1897,7 @@ def preload_module_type_components(self, module_type_ids, component_keys): ``filter()`` call per chunk of up to ``FILTER_CHUNK_SIZE`` module-type IDs (filtering by module_type_id=[...]) and distributes the returned items into per-module-type cache entries so that subsequent ``_get_cached_or_fetch`` - calls hit the cache. + calls hit the cache.

The flag was plumbed for device types (netbox_api.py:430-438) but never forwarded to create_module_types/_process_single_module_type, so stale module components could never be deleted and reappeared in change detection on every run. Bug 2: as a consequence, module types whose only diff was a removed component remained in the actionable list forever, logging 'Module Type Cached: ...' on every run with no possible resolution. Bug 3: argparse default allow_abbrev=True meant '--remove' was accepted as a prefix of '--remove-components'. This silently grabs any future '--remove-*' flag we add. Disabled abbreviations. Changes: - ArgumentParser(allow_abbrev=False) - Plumb remove_components through _process_module_types -> create_module_types -> _process_single_module_type, which now calls self.device_types.remove_components(..., parent_type='module') and bumps module_updated when a removal actually happens - New advisory line in MODULE TYPE CHANGE DETECTION report: '(Run with --remove-components to remove N stale component(s) across M module type(s))' when removals are pending and the flag is not set --- core/netbox_api.py | 12 +++++++++++- nb-dt-import.py | 23 +++++++++++++++++++++-- 2 files changed, 32 insertions(+), 3 deletions(-) diff --git a/core/netbox_api.py b/core/netbox_api.py index 1a2477dc..9362272d 100644 --- a/core/netbox_api.py +++ b/core/netbox_api.py @@ -921,7 +921,9 @@ def _try_update_module_type(self, curr_mt, module_type_res, src_file): return False, False return True, True - def _process_single_module_type(self, curr_mt, src_file, all_module_types, module_type_existing_images, only_new): + def _process_single_module_type( + self, curr_mt, src_file, all_module_types, module_type_existing_images, only_new, remove_components=False + ): """Find or create a single module type and create or update its component templates.

After the GraphQL pagination completes, compare the actual count against the expected value and log a prominent WARNING if they differ.

modules from modified count - core/netbox_api.py: _get_endpoint_totals now preserves None sentinel from _get_rest_component_count (real REST count of 0 is distinct from 'count unavailable'). _fetch_global_endpoint_records uses 'is not None' so a real REST count of 0 paired with a non-empty GraphQL response still raises GraphQLCountMismatchError instead of silently passing. - nb-dt-import.py: 'Modified module types' counter now uses len(changed_property_log) so image-only updates (handled in default mode) are not counted as modified and do not trigger the misleading '--update' hint. Added separate 'Image-only updates' line when applicable. - tests: updated test_get_endpoint_totals_tolerates_count_failure to assert None; added test_fetch_global_endpoint_records_detects_mismatch_when_rest_returns_zero regression test. --- core/netbox_api.py | 9 ++++--- nb-dt-import.py | 8 +++++- tests/test_netbox_api.py | 53 ++++++++++++++++++++++++++++++++++++++-- 3 files changed, 64 insertions(+), 6 deletions(-) diff --git a/core/netbox_api.py b/core/netbox_api.py index ee3e6b95..07c9e220 100644 --- a/core/netbox_api.py +++ b/core/netbox_api.py @@ -1444,10 +1444,13 @@ def _get_endpoint_totals(self, components): components: Iterable of ``(endpoint_name, label)`` tuples.

Fixes the case where the module is imported before the repo schema is on disk (fresh environments, test bootstrap) which would have permanently pinned the comparison to the fallback property list. The eager DEVICE_TYPE_PROPERTIES constant is kept for backwards compatibility with existing tests/imports. - core/netbox_api.py: don't early-return from create_module_types when the scalar PATCH fails. An existing module with both property and component diffs would previously fail the PATCH and skip component reconciliation, leaving NetBox in a partial-sync state. Log a verbose warning instead and continue with component reconciliation. - tests/test_netbox_api.py: * derive expected retry/sleep counts from _MAX_RETRIES instead of hardcoding 3 in the count-mismatch retry test. * strengthen the three TestCreateModuleTypesEdge tests to assert the actual ComponentChange / PropertyChange payload passed to update_components, not just that update_components was called.

Live progress for global GraphQL fetches - _fetch_global_endpoint_records now emits per-page progress live instead of buffering until the whole fetch completes; the Interfaces bar (largest endpoint) now ticks during the fetch instead of jumping from 0/N to 100% at the end. - On count-mismatch retry, emits a negative-advance rewind so the bar rolls back to the prior baseline before the next attempt; consumers clamp completed at 0 to keep the UI clean. B. Constraint-aware device-type updates (--force-resolve-conflicts) - New core/update_failure_resolver.py classifies pynetbox.RequestError payloads (currently: subdevice_role parent->child constraint). - Mandatory in-use safety check: queries dcim.devices for live references; any live device or query failure forces MANUAL_REQUIRED even with the flag set. - New --force-resolve-conflicts CLI flag (requires --update). Without it, failed PATCHes log an actionable hint listing the blocking templates. With it, the script deletes the blocking device-bay templates and retries the PATCH once. - YAML still declaring device-bays blocks auto-resolve to avoid an update->delete->recreate loop. C. Structured failure report (additive) - New core/outcomes.py provides OutcomeRegistry; failed and partial device-type updates are recorded with reason, blocking objects, and hint. - End-of-run summary now prints a 'FAILURE REPORT' block whenever any failures or partials were recorded, replacing the old hand-wavy 'see error log above' counter line.

Added tests asserting device_type_id vs devicetype_id key depending on new_filters flag. - 3174932529 (Major): Add module_update_failed counter. Increment when _try_update_module_type returns ok=False. Surface in run summary when non-zero. Test now asserts module_updated==0 and module_update_failed==1 for the failed-PATCH scenario. - 3174932523 (Major): _FrontPortRecordWithMappings._mappings_canonical is now None (not []) when both mappings and rear_port_position are absent. change_detector skips the _mappings comparison when canonical is None, preventing a spurious COMPONENT_CHANGED false diff. - 3174932549 (Minor): Add assert nb.counter['module_updated'] == 0 and assert nb.counter['module_update_failed'] == 1 to the failed-PATCH test. - 3174932544 (Minor): _MISSING sentinel test now patches get_device_type_properties() to a fixed list; removes fragile coupling to DEVICE_TYPE_PROPERTIES constant value. - 3174932547 (Minor): _make_mock_netbox seeds counter with concrete integers (module_added=3, module_updated=2); module count test now asserts exact log strings '3 modules created' / '2 modules updated'. - 3174932551 (Trivial): load_scalar_properties guards non-dict schema root with ValueError; non-dict property entries are silently skipped.

From f3be4e55dc7187096fd558edeff7a12f0f64ad19 Mon Sep 17 00:00:00 2001 From: Marcin Zieba Date: Sat, 2 May 2026 09:37:17 +0200 Subject: [PATCH 54/64] fix: re-raise preload errors instead of swallowing and caching empty records When a background future fails during _preload_track_progress or _preload_no_progress, storing [] into records_by_endpoint silently corrupts the cache: every existing component for that endpoint appears missing on the next diff, triggering spurious removals or missed updates. Fix: remove the fallback assignment and re-raise the exception in all three error-handler blocks (already-done and pending paths of _preload_track_progress, and _preload_no_progress). The log message is still emitted before re-raising so the operator sees which endpoint failed. Since _global_preload_done is only set after _preload_global returns successfully, a partial cache can never be used for a subsequent import run.

Device-type path (_log_device_type_change_outcome): - Replaces component_attempted/component_succeeded bool params with component_delta/actionable_count int params; derives the booleans inside. - Adds is_full_success guard: UPDATED only when every attempted op succeeded; otherwise logs Device Type Partially Updated with a "X of N" reason. - Gates device_types_component_updates increment on component_delta > 0. Module-type path (_apply_module_type_component_updates): - Replaces _any_actionable_component_changes + actually_changed bool with _count_actionable_component_changes + component_delta int. - delta == actionable_count && patch_ok → module_updated; delta == 0 && patch_ok → module_update_failed (patch_ok guard avoids double-count with scalar PATCH failure already recorded at call site); otherwise → module_partial_update. - Adds module_partial_update=0 to Counter init and to the summary printer. Also renames _any_actionable_component_changes to _count_actionable_component_changes (returns int) and removes the now-unused bool variant.

This prevents properties with anyOf, oneOf, allOf, or an absent 'type' from being treated as comparable scalars — avoiding bogus PATCH calls when the NetBox device-type library schema later gains such entries. Verified against all three real schemas (devicetype.json, moduletype.json, racktype.json): every property currently included by the old logic is also included by the new allowlist. Add 4 new tests: - test_skips_property_with_no_type_and_no_ref - test_skips_anyof_and_oneof_properties - test_includes_nullable_scalar_union_type - test_skips_type_union_containing_array_or_object Closes #66 --- core/schema_reader.py | 34 ++++++++++++++----- tests/test_schema_reader.py | 68 +++++++++++++++++++++++++++++++++++++ 2 files changed, 93 insertions(+), 9 deletions(-) diff --git a/core/schema_reader.py b/core/schema_reader.py index e2291ad9..171d6167 100644 --- a/core/schema_reader.py +++ b/core/schema_reader.py @@ -8,19 +8,25 @@ import json import os +# All JSON Schema primitive types that are safe to compare and PATCH as scalars. +_SCALAR_TYPES = frozenset({"string", "integer", "number", "boolean", "null"}) + def load_scalar_properties(schema_path, exclude=None): """Read a JSON schema file and return names of comparable scalar properties.
