From 13244fd358a5472dab9d02c2d7b84c55904eabee Mon Sep 17 00:00:00 2001 From: Rithvick Reddy Munagala Date: Tue, 21 Jul 2026 15:34:20 -0400 Subject: [PATCH 01/10] [202405][GCU perf backport #3831 - part 1/N] Config-threading refactor: fetch config once per patch, thread through ChangeApplier Backport of the config-threading portion of upstream sonic-net/sonic-utilities PR #3831 to the 202405 branch, mirroring the 202412 auto-backport (PR #254). Motivation: On 202405 the ChangeApplier.apply() path calls get_config_db_as_json() twice per JsonChange (once to seed the deepcopy, once for the post-apply sanity check). At MOR scale (N=14 => 381 changes) this dominates wall clock time and yields the flat ~1.47s/change floor observed in the sonic-mgmt scaling test. This change: * JsonChange.apply(config) -> JsonChange.apply(config, in_place=False) * DryRunConfigWrapper.apply_change_to_config_db(change) -> apply_change_to_config_db(current_config_db, change) and returns the updated dict. * ChangeApplier.apply(change) -> apply(current_configdb, change) -> dict - drops the deepcopy (uses in_place=False on JsonChange.apply) - drops the redundant post-apply get_config_db_as_json + jsondiff sanity check; replaces it with a 1s sleep race-guard (matches upstream #3831 behavior; upstream SONiC issue tracks proper fix). - returns the updated in-memory config dict. * DryRunChangeApplier.apply likewise threads and returns config. * PatchApplier.apply now fetches old_config once, seeds current_config from it, and threads current_config = self.changeapplier.apply( current_config, change) through the change loop. Tests updated to match new signatures: * change_applier_test.py: mock_obj.apply(config, in_place), applier call sites pass current_config, DryRunChangeApplier test updated. * multiasic_change_applier_test.py: @patch targets moved from change_applier.get_config_db_as_json to gu_common.get_config_db_as_json (since change_applier no longer re-exports it), applier call sites updated, `import copy` added. * generic_updater_test.py: TestPatchApplier now asserts changeapplier.apply.assert_called() and the mock side_effect accepts (current_config, change) and returns the config through. * gu_common_test.py: DryRunConfigWrapper multi-call test threads the returned config through the loop. Deliberately out of scope for this commit (will land in follow-ups): * skip_sort_tables.txt handling (perpetuates a shortcut we want to eliminate on 202412; not required for perf win). * illegal_dataacl_check (comes from upstream PR #3668, not #3831). * PathAddressing xpath cache rewrite and find_ref_paths batch API. * BulkLowLevelMoveGenerator family (patch_sorter additive changes). * extract_scope multi-ASIC guard.

part 2/N] PathAddressing xpath cache + batch find_ref_paths Backport of the gu_common.py PathAddressing portion of upstream sonic-net/sonic-utilities PR #3831 to 202405, mirroring 202412 auto-backport (Azure/sonic-utilities.msft PR #254). Motivation: On 202405, PathAddressing rebuilds its sonic-yang xpath token index from scratch on every conversion call. At MOR scale (14 hosts * 27+ paths per patch = several hundred conversions per apply) this produces the O(N) yang-tree-walk cost observed as the second-largest contributor to GCU wall-clock time after the double get_config_db_as_json addressed in part 1. Also, find_ref_paths(path, ...) took a single path and had to reload config for every call. The batched find_ref_paths(paths, ...) walks config once per batch. This change: * PathAddressing xpath cache rewrite: retire the ~500 lines of _get_xpath_tokens_from_* / _get_path_tokens_from_* walkers + _get_*_model / _find_leafref_paths helpers. Replace with a hash-keyed loadData cache so repeated conversions on the same config skip the yang reload. Public convert_path_to_xpath, convert_xpath_to_path, get_path_tokens, get_xpath_tokens, create_path, has_path, get_from_path, is_config_different signatures unchanged. * find_ref_paths(path, ...) -> find_ref_paths(paths, ...) batch API. Accepts either a single path (str) or a list of paths. * New helpers: configdb_sorted_keys_by_backlinks and configdb_sort_cmp used by patch_sorter's Bulk generators (added in part 3). * DryRunConfigWrapper.apply_change_to_config_db signature retained from part 1 (current_config_db threaded, returns updated dict). * JsonChange.apply(config, in_place=False) retained from part 1. Test file wholesale-replaced from 202412 (adds caching-behavior tests test_validate_config_db_config__same_config_called_twice__loadData_called_once, test_find_ref_paths__after_validate_same_config__loadData_skipped, etc; retires create_xpath / walker tests whose helpers are being deleted). Deliberately excluded (not part of #3831): * ConfigWrapper.illegal_dataacl_check (from upstream PR #3668).

part 3/N] patch_sorter: JsonMoveGroup + Bulk generators + validator refactor Backport of the patch_sorter.py portion of upstream sonic-net/sonic-utilities PR #3831 to 202405, mirroring 202412 auto-backport (Azure/sonic-utilities.msft PR #254). Motivation: On 202405 the move-generation engine emits one JsonMove per individual field/key delta, and each JsonMove goes through full-graph validation independently. At MOR scale (14 hosts) the sorter emits several hundred moves, and validators reload sonic-yang xpath state on every call. Combined with the per-move DB roundtrip removed in part 1, this is the second-largest contributor to observed GCU wall-clock time. This change ports the sorter/validator rewrite: New: * JsonMoveGroup - a mergeable group of JsonMoves. apply()/undo() fold a whole group into config in one pass, in_place-aware. * BulkLowLevelMoveGenerator, BulkKeyLevelMoveGenerator, BulkKeyGroupLowLevelMoveGenerator - emit JsonMoveGroups that coalesce many single-field/key deltas into one add/remove/replace move per subtree, with restricted-only fallback for correctness. * MoveWrapper.apply_move / undo_move now take in_place: bool. * Simulator.simulate / undo_simulate now take in_place: bool. Refactor: * All *MoveValidator.validate signatures unified to (group: JsonMoveGroup, diff, simulated_config) - the simulated config is now computed once by the caller and passed in, instead of each validator recomputing it. * _extend_moves(moveGroup) and target_in_required_pattern helpers. * KeyLevelMoveGenerator / LowLevelMoveGenerator retained but now delegate to the Bulk variants under the hood via generate_groups with restricted_only fallback. * find_ref_paths now called with a paths batch and reload_config hint at PatchSorter._validate_paths_config; the reload skip is what unlocks the xpath cache added in part 2. Retired: * SingleRunLowLevelMoveGenerator - internal-only, replaced by BulkLowLevelMoveGenerator's generate_remove/replace/add. External API preserved: * StrictPatchSorter, NonStrictPatchSorter, PatchSorter, ConfigSplitter, TablesWithoutYangConfigSplitter, IgnorePathsFromYangConfigSplitter (the six symbols imported by generic_updater.py) - all signatures unchanged. Test file wholesale-replaced from 202412 - covers the new Bulk generators, JsonMoveGroup, and updated validator signatures.

No functional changes to the ported feature - only completes the port. Fixes: 1. gu_common.py: remove call site of deleted illegal_dataacl_check Part 2 removed the illegal_dataacl_check method as out-of-scope (from upstream PR #3668, not #3831) but left the caller in validate_field_operation, which would AttributeError at runtime. 2. generic_updater.py: add missing 'import jsonpatch' and add 'JsonChange' to the .gu_common import list. This is a pre-existing latent bug on 202405: PatchApplier.apply(patch, sort=False) uses JsonChange(jsonpatch.JsonPatch([element])) but neither symbol was imported. NameError only surfaces when the sort=False path is exercised. Upstream 202412 already imports both. 3. tests/generic_config_updater/gutest_helpers.py: add JsonMoveGroup import + create_side_effect_skiplastarg_dict, create_side_effect_skipfirstarg_dict, create_side_effect_jsonmovegroup_dict factories. These helpers are referenced by the 202412-shape patch_sorter_test.py added in part 3 - without them, patch_sorter_test collection fails. 4. tests/generic_config_updater/gcu_feature_patch_application_test.py: drop @patch('generic_config_updater.change_applier.get_config_db_as_json', ...) decorators. Part 1 dropped the get_config_db_as_json re-export from change_applier.py; mock decorators pointing at the removed attribute would AttributeError at test-setup time. 5. tests/generic_config_updater/files/patch_sorter_test_success.json: refresh golden fixture. The Bulk generators added in part 3 emit coalesced 'replace' moves on whole arrays where the old sorter emitted a sequence of per-element 'add' moves - the e2e success tests compare emitted output to this fixture. 6. tests/generic_config_updater/change_applier_test.py: drop stray local `running_config = {}` that shadowed the module-level global (functionally identical, but keeps parity with 202412 shape). After these fixes, our branch's diff vs Azure/sonic-utilities.msft:202412 for the ported prod files is: change_applier.py: 0 (identical) patch_sorter.py: 0 (identical) gu_common.py: -45 (illegal_dataacl_check method only) generic_updater.py: -29 (skip_sort_tables block + extract_scope multi-ASIC guard + import fnmatch) And for test files, only the tests exercising the three deliberately excluded features differ.

Nexthop Date: Mon, 27 Apr 2026 12:32:30 -0400 Subject: [PATCH 05/10] [202405][GCU perf backport #3831 - part 5/N] Backport upstream #4118: remove direct libyang dependency in gu_common.find_ref_paths Cherry-pick of upstream sonic-utilities#4118 (4b787b0f). Removes _get_inner_leaf_xpaths (which called sy.root.find_path and hit AttributeError when sy was uninitialized after #4476 caching) and simplifies find_ref_paths to delegate directly to sonic-yang-mgmt find_data_dependencies. Depends on sonic-buildimage#24414 (sonic-yang-mgmt recursive find_data_dependencies w/ match_ancestors) tracked in buildimage-msft PR #2733.

Root-cause analysis showed one was a production-side wiring bug and the other two were test-side staleness against the port shape. Production fix (Group B — 3 factory tests): Part 6 (backport #4335) commit message stated that BulkLeafListMoveGenerator was re-added to SortAlgorithmFactory.move_non_extendable_generators, but the actual edit did not land. The class definition survives (from the #4478 backport already in main), but the factory never instantiates it, so leaf-list changes fall through to granular remove/add sequences. Wire BulkLeafListMoveGenerator into move_non_extendable_generators. This also automatically fixes 4 of 6 TestPatchSorter subtests that pinned the leaf-list batching REPLACE emission (ADD_VALUE_TO_EXISTING_ARRAY, MODIFY_VALUE_IN_EXISTING_ARRAY, PATCH_WITH_SINGLE_SIMPLE_OPERATION, DPB_1_TO_4). Test-side adaptations: Group A (5 tests): tests call JsonMoveGroup("", JsonMove(...)) with a legacy generator_name first arg. Our port intentionally dropped that arg (part 6 commit message: 'dropped generator_name arg to match our port signature'). Test file was not updated at that time. Removed the "" first arg from 3 call sites. Also fixed 4 assertFalse(validator.validate(...)[0]) call sites — the tests expect a tuple return, but our validators return bool (upstream moved to a tuple contract in a PR we have not backported and do not intend to for parts 1-7). Dropped the [0] subscript. Group C (2 remaining subtests): ADD_RACK, REMOVE_RACK have genuine move-ordering drift from #4335 (part 6) — the plan-aware CreateOnly generator legitimately changes exploration order for multi-table patches, producing semantically equivalent but syntactically different patch sequences. Added a per-fixture skip_exact_change_list_match flag in the JSON, and updated run_single_success_case to honor it. The simulated_config == target_config assertion still runs, so functional correctness is verified — only the strict emitted-patch-list equality is skipped for these two fixtures. Verified: 197 tests + 79 subtests pass, 0 failures.

Adapted only for this branch's test-class style: pytest.raises -> self.assertRaises, because TestValidateFieldOperation subclasses unittest.TestCase here whereas master uses a plain pytest class. This is the test that exercises ConfigWrapper.validate_field_operation end-to-end through the validator dispatch, and therefore guards the scope argument being forwarded to field operation validators. --- .../field_operation_validator_test.py | 38 +++++++++++++++++++ 1 file changed, 38 insertions(+) diff --git a/tests/generic_config_updater/field_operation_validator_test.py b/tests/generic_config_updater/field_operation_validator_test.py index 72a5b2abe..f31fa36f9 100644 --- a/tests/generic_config_updater/field_operation_validator_test.py +++ b/tests/generic_config_updater/field_operation_validator_test.py @@ -229,6 +229,44 @@ def test_validate_field_operation_illegal__pfcwd(self): config_wrapper = gu_common.ConfigWrapper() self.assertRaises(gu_common.IllegalPatchOperationError, config_wrapper.validate_field_operation, old_config, target_config) + @patch("sonic_py_common.device_info.get_sonic_version_info", + mock.Mock(return_value={"build_version": "20241211.49"})) + @patch("generic_config_updater.field_operation_validators.get_asic_name", + mock.Mock(return_value="spc1")) + @patch("os.path.exists", mock.Mock(return_value=True)) + @patch( + "builtins.open", + mock_open( + read_data=( + '{"tables": {"BUFFER_POOL": {' + '"field_operation_validators": [' + '"generic_config_updater.field_operation_validators.rdma_config_update_validator"' + '], "validator_data": {"rdma_config_update_validator": {"Blocked ops": ' + '{"fields": ["ingress_lossless_pool/xoff", ' + '"ingress_lossless_pool/size", "egress_lossy_pool/size"], ' + '"operations": [], "platforms": {"spc1": "20181100"}}}}}}}' + ) + ) + ) + def test_validate_field_operation_illegal__buffer_pool(self): + old_config = { + "BUFFER_POOL": { + "ingress_lossless_pool": {"xoff": "1000"} + } + } + target_config = { + "BUFFER_POOL": { + "ingress_lossless_pool": {"xoff": "2000"} + } + } + config_wrapper = gu_common.ConfigWrapper() + self.assertRaises( + gu_common.IllegalPatchOperationError, + config_wrapper.validate_field_operation, + old_config, + target_config + ) + def test_validate_field_operation_legal__rm_loopback1(self): old_config = { "LOOPBACK_INTERFACE": {
