128-128: Consider usingget_root_node_id()in the constructor.The constructor now uses a factory method to create the root node, which is a good practice. However, for consistency and to leverage the newly added
get_root_node_id()method, consider updating the constructor as follows:- SchemaTree() { m_tree_nodes.emplace_back(SchemaTreeNode::create_root(cRootId)); } + SchemaTree() { m_tree_nodes.emplace_back(SchemaTreeNode::create_root(get_root_node_id())); }This change would ensure that the root node ID is always accessed through the centralized method.
144-144: Approve the addition ofget_root()method with a minor suggestion.The
get_root()method is a good addition, providing direct access to the root node. However, for consistency, consider using theget_root_node_id()method instead ofcRootId:- [[nodiscard]] auto get_root() const -> SchemaTreeNode const& { return m_tree_nodes[cRootId]; } + [[nodiscard]] auto get_root() const -> SchemaTreeNode const& { return m_tree_nodes[get_root_node_id()]; }This change would ensure consistent access to the root node ID throughout the class.
192-194: Approve movingcRootIdto private section with a minor suggestion.Moving
cRootIdto the private section improves encapsulation, which is a good practice. To further improve the code, consider updating the constant name to follow the common C++ naming convention for private constants:- static constexpr SchemaTreeNode::id_t cRootId{0}; + static constexpr SchemaTreeNode::id_t kRootId{0};This change would make the code more consistent with typical C++ style guidelines.

110-112: Excellent update to useSchemaTree::get_root_node_id()This change aligns well with the PR objectives. Using
SchemaTree::get_root_node_id()instead of directly accessingSchemaTree::cRootIdis a more flexible approach. It encapsulates the logic of retrieving the root node ID, which is particularly beneficial given the new implementation where the root node's parent ID can be null.This modification enhances the test's robustness by ensuring it uses the correct method to obtain the root node ID, regardless of how it's internally represented in the
SchemaTreeclass.components/core/src/clp/ffi/SchemaTree.hpp (2)
122-125: Good addition of a static method for root node ID access.The
get_root_node_id()method provides a centralized and encapsulated way to access the root node ID. Using a static method instead of a public constant improves encapsulation, and theconstexprspecifier ensures compile-time evaluation when possible, which is good for performance.

269-270: Improved root node ID handling and code readabilityThese changes enhance the code in two ways:
- Replacing
SchemaTree::cRootIdwithSchemaTree::get_root_node_id()aligns with the new schema tree node implementation using an optional ID for the parent node. This improves clarity and maintainability.- Splitting the single line into two lines enhances readability and adheres to common coding standards for line length.

optional_parent_id.has_value()before accessingoptional_parent_id.value(). This ensures that the code safely handles nodes that may not have a parent, preventing potential runtime errors.components/core/tests/test-ffi_SchemaTree.cpp (2)
54-74: The implementation ofcheck_nodefunction is correct.The logic within the
check_nodefunction appropriately validates the node's existence, ID, parent ID, type, and key name against the provided locator. The checks ensure the node is not the root and all attributes match as expected.

node.is_root()to ensure that the root node is not included innode_id_value_pairs, maintaining the integrity of the schema tree.
245-247: Clear explanation of safety assumptionsThe added comments effectively clarify that it's safe to call
get_parent_id_unsafe()because the node is confirmed not to be the root, improving code readability.

52-72: Excellent enhancement to node validation process.The updated
check_nodefunction now performs a more comprehensive validation of the node, including checks for existence, ID, root status, parent ID, type, and key name. These changes significantly improve the robustness of the node validation process and align well with the PR objective of better handling the parent-child relationship.However, there's a minor grammatical error in the function documentation:
On line 29, "matches the ones specified" should be "match the ones specified" to maintain subject-verb agreement.
components/core/src/clp/ffi/SchemaTree.hpp (2)
94-210: LGTM: Addition of Node class with suggestionThe new
Nodeclass is a well-structured addition that improves encapsulation and provides a clear interface for node operations. The use ofstd::optional<id_t>for the parent ID is a good design choice, allowing for a semantically correct representation of the root node.The class correctly implements the rule of five, and the factory methods ensure proper initialization of root and non-root nodes.
Suggestion for improvement:
Consider adding astatic_assertin thecreate_root()method to ensure thatcRootIdis always 0. This would help prevent potential future issues if the value ofcRootIdis ever changed.[[nodiscard]] static auto create_root() -> Node { static_assert(cRootId == 0, "Root ID must be 0"); return {cRootId, std::nullopt, "", Type::Obj}; }
256-257: LGTM: Addition of get_root() method with suggestionThe new
get_root()method is a valuable addition, providing direct access to the root node of the schema tree. The use of[[nodiscard]]and returning a const reference are good practices.Suggestion for improvement:
Consider adding a debug assertion to ensure that the root node always exists and has the expected properties. This can help catch potential issues during development:[[nodiscard]] auto get_root() const -> Node const& { assert(!m_tree_nodes.empty() && "Tree nodes vector should never be empty"); assert(m_tree_nodes[cRootId].is_root() && "First node should always be the root"); return m_tree_nodes[cRootId]; }components/core/src/clp/ffi/ir_stream/ir_unit_deserialization_methods.cpp (3)

54-76: Modify 'deserialize_schema_tree_node_parent_id' to handle optional parent IDsThe function 'deserialize_schema_tree_node_parent_id' currently accepts 'SchemaTree::Node::id_t& parent_id' as a parameter. To accommodate the possibility of a null parent ID (for the root node), the parameter should be changed to 'std::optionalSchemaTree::Node::id_t& parent_id'.
Apply this diff to update the function signature and handle optional parent IDs:
- auto deserialize_schema_tree_node_parent_id( - ReaderInterface& reader, - SchemaTree::Node::id_t& parent_id +) -> IRErrorCode { + ReaderInterface& reader, + std::optional<SchemaTree::Node::id_t>& parent_id +) -> IRErrorCode { encoded_tag_t tag{}; if (auto const err{deserialize_tag(reader, tag)}; IRErrorCode::IRErrorCode_Success != err) { return err; } if (cProtocol::Payload::SchemaTreeNodeParentIdNull == tag) { + parent_id = std::nullopt; } else if (cProtocol::Payload::SchemaTreeNodeParentIdUByte == tag) { uint8_t deserialized_id{}; if (false == deserialize_int(reader, deserialized_id)) { return IRErrorCode::IRErrorCode_Incomplete_IR; } parent_id = static_cast<SchemaTree::Node::id_t>(deserialized_id); } else if (cProtocol::Payload::SchemaTreeNodeParentIdUShort == tag) { uint16_t deserialized_id{}; if (false == deserialize_int(reader, deserialized_id)) { return IRErrorCode::IRErrorCode_Incomplete_IR; } parent_id = static_cast<SchemaTree::Node::id_t>(deserialized_id); } else { return IRErrorCode::IRErrorCode_Corrupted_IR; } return IRErrorCode_Success; }This modification ensures that the root node's parent ID can be represented as 'std::nullopt'.
Line range hint
198-224: Change 'parent_id' to optional in function implementationsThroughout the function 'deserialize_schema_tree_node_parent_id', 'parent_id' is treated as a non-optional type. Given the new implementation where 'parent_id' can be null, the function should accommodate this by using 'std::optionalSchemaTree::Node::id_t'.
Ensure that 'parent_id' is consistently treated as an optional type and handle the null case appropriately.
Line range hint
511-523: Adjust 'deserialize_ir_unit_schema_tree_node_insertion' to handle optional 'parent_id'In the function 'deserialize_ir_unit_schema_tree_node_insertion', 'parent_id' is declared as 'SchemaTree::Node::id_t'. To support a null parent ID for the root node, it should be an optional type.
Apply this diff to update the variable declaration and handle the null parent ID:
- SchemaTree::Node::id_t parent_id{}; + std::optional<SchemaTree::Node::id_t> parent_id{}; if (auto const err{deserialize_schema_tree_node_parent_id(reader, parent_id)}; IRErrorCode_Success != err) { return ir_error_code_to_errc(err); }Additionally, adjust the construction of 'SchemaTree::NodeLocator' to accept an optional 'parent_id':
return SchemaTree::NodeLocator{parent_id, key_name, type.value()};

20-21: LGTM: Improved function signatureThe changes to the
insert_nodefunction signature are appropriate:
- Using
SchemaTree::Node::id_taligns with the updated schema tree node implementation.- Passing
locatorby const reference can improve performance by avoiding unnecessary copying.These modifications enhance consistency and efficiency.
28-29: Grammatical error fixed in function documentationThe documentation for the
check_nodefunction has been updated to correct the grammatical error. The phrase now reads "matches the ones" instead of "matched the ones", maintaining consistent tense and improving clarity.Thank you for addressing this issue from the previous review.
33-34: LGTM: Consistent improvements in function signatureThe changes to the
check_nodefunction signature mirror those made toinsert_node:
- Using
SchemaTree::Node::id_tmaintains consistency with the updated schema tree node implementation.- Passing
locatorby const reference can enhance performance.These modifications ensure consistency across the codebase and potentially improve efficiency.
39-40: LGTM: Consistent function signature updateThe
insert_nodefunction implementation has been updated to match the earlier changes in its signature:
- The
locatorparameter is now a const reference.- The expected ID type is now
SchemaTree::Node::id_t.These changes maintain consistency with the function declaration while preserving the original logic.
48-72: Excellent refactoring of thecheck_nodefunctionThe
check_nodefunction has been significantly improved:
It now performs a more comprehensive validation of the node, including checks for:
- Node ID existence and matching
- Root node status
- Parent ID presence for non-root nodes
- Consistency between node information and locator data
The implementation correctly handles the new schema tree node structure, where the root node's parent ID is null.
The function returns early if any check fails, improving efficiency.
These changes align well with the PR objectives and provide a more robust validation process for schema tree nodes.
92-97: Improved root node validation in test setupThe test case setup for the root node has been enhanced:
The use of
SchemaTree::get_root_node_id()instead of a hardcoded value improves maintainability and reduces the risk of errors if the root ID implementation changes.The additional check
REQUIRE_FALSE(root.get_parent_id().has_value())ensures that the root node's parent ID is null, aligning with the new schema tree node implementation.These changes improve the robustness of the test case and ensure it correctly validates the updated schema tree structure.
100-132: Consistent improvements in test case implementationThe test case implementation has been updated to align with the earlier changes:
The locators vector now uses
SchemaTree::get_root_node_id()instead of a hardcoded value for the root node ID, improving maintainability and consistency.Loop counters and comparisons now use
SchemaTree::Node::id_t, ensuring type consistency throughout the test case.These modifications enhance the overall quality of the test case by maintaining consistency with the updated schema tree node implementation and improving code maintainability.

Potential null dereference when accessing parent node in insert_node
In the insert_node method, you access locator.get_parent_id() without checking if it has a value:
auto& parent_node{m_tree_nodes[locator.get_parent_id()]};Since locator.get_parent_id() can now be std::nullopt for the root node, accessing m_tree_nodes[locator.get_parent_id()] without checking may lead to undefined behaviour.
Consider checking whether locator.get_parent_id() has a value before accessing m_tree_nodes[locator.get_parent_id().value()].
Apply this diff to fix the issue:

🛠️ Refactor suggestion
Consistent handling of optional parent IDs
In the revert method, you correctly check if node.get_parent_id() has a value before accessing it:
auto const optional_parent_id{node.get_parent_id()};
if (optional_parent_id.has_value()) {
m_tree_nodes[optional_parent_id.value()].remove_last_appended_child();
}Consider applying the same pattern in other methods, such as insert_node and try_get_node_id, to ensure consistent and safe handling of optional parent IDs throughout the codebase.

Technically this is implicitly checked by try_get_node.

that is correct, but adding this in the unit test is also checking the functionality of try_get_node works properly right?

28-29: Improved function documentation with minor grammatical suggestion.The updated return description for the
check_nodefunction provides a more comprehensive explanation of the conditions being checked. This improvement enhances the clarity and usefulness of the documentation.However, there's a minor grammatical issue that could be addressed:
- * @return Whether an ID could be found for a node matching the locator, the ID matches the expected - * ID, the corresponding node is not the root, and it matches the locator. + * @return Whether an ID could be found for a node matching the locator, the ID matches the expected + * ID, the corresponding node is not the root, and the node matches the locator.This small change improves the readability of the documentation.
components/core/src/clp/ffi/SchemaTree.hpp (1)
94-208: LGTM: Well-designed Node class implementationThe new Node class is well-structured and encapsulates the properties and behaviour of a schema tree node effectively. The use of std::optional<id_t> for the parent ID is a good choice for representing the root node. The factory methods ensure proper initialization, and the const qualifiers and [[nodiscard]] attributes are used appropriately.
However, I have two minor suggestions for improvement:
- Consider adding the [[nodiscard]] attribute to the
append_new_childmethod:- auto append_new_child(id_t child_id) -> void { m_children_ids.push_back(child_id); } + [[nodiscard]] auto append_new_child(id_t child_id) -> void { m_children_ids.push_back(child_id); }
- For the
get_parent_id_unsafemethod, consider throwing a more specific exception type when accessed on a root node, instead of relying on std::optional's behaviour:[[nodiscard]] auto get_parent_id_unsafe() const -> id_t { - // NOLINTNEXTLINE(bugprone-unchecked-optional-access) - return m_parent_id.value(); + if (!m_parent_id.has_value()) { + throw std::logic_error("Attempted to access parent ID of root node"); + } + return *m_parent_id; }These changes would enhance the safety and clarity of the Node class interface.

48-72: Excellent refactoring of thecheck_nodefunction.The
check_nodefunction has been significantly improved:
More comprehensive validation:
- Checks if the node ID exists and matches the expected ID.
- Verifies that the node is not the root.
- Ensures non-root nodes have a parent ID.
- Validates that the node's type and key name match the locator.
Enhanced efficiency:
- Early returns when any check fails, avoiding unnecessary processing.
Improved readability:
- Clear comments explaining each check.
- Logical grouping of related checks.
These changes align perfectly with the updated function documentation and provide a more robust validation process. The refactoring enhances both the functionality and maintainability of the code.
92-97: Improved root node validation in test setup.The updates to the root node checks in the test setup are well-considered:
Using
SchemaTree::get_root_node_id()instead of a hardcoded value improves consistency and makes the test more robust against potential changes in the root node ID implementation.The new check
REQUIRE_FALSE(root.get_parent_id().has_value())ensures that the root node correctly has no parent ID, aligning with the updated SchemaTree implementation.These changes enhance the test coverage and make the tests more resilient to future modifications in the SchemaTree class.
100-107: Consistent use ofSchemaTree::get_root_node_id()in test locators.The update to use
SchemaTree::get_root_node_id()in the test locators is a positive change:
- It maintains consistency with the earlier modifications in the test setup.
- This change further reduces hardcoding of the root node ID.
- It improves the test's resilience to potential future changes in the root node ID implementation.
This modification ensures that the test cases remain valid even if the underlying implementation of the root node ID changes, contributing to more robust and maintainable tests.
112-112: Improved type consistency in test loops.The update to use
SchemaTree::Node::id_tforid_to_insertandid_to_checkin the test loops is a positive change:
- It maintains consistency with the earlier modifications in the
insert_nodeandcheck_nodefunctions.- This change ensures type consistency throughout the test case, reducing the risk of subtle type-related bugs.
- It improves code readability by using the specific type defined by the SchemaTree class.
These modifications contribute to a more robust and maintainable test suite by ensuring type consistency across all parts of the test case.

Clarification needed: Removal of reset() method
The
reset()method has been removed from the SchemaTree class. Could you please clarify the reasoning behind this removal and confirm that it won't negatively impact existing code that might rely on this method? If the functionality is no longer needed, consider adding a comment explaining why it was removed to maintain clear documentation of the class's evolution.components/core/src/clp/ffi/KeyValuePairLogEvent.cpp (8)
51-51: Usage of raw pointer form_schema_tree_nodeis acceptable in this contextThe initialization with
SchemaTree::Node const* schema_tree_nodeis appropriate here, considering the ownership and lifetime are managed elsewhere.
78-78: Correct usage ofis_root()methodThe check
if (m_schema_tree_node->is_root())enhances readability and accurately handles the root node case.
102-102: Proper implementation ofget_next_child_schema_tree_node()The method correctly retrieves the next child schema tree node, assuming prior verification with
has_next_child_schema_tree_node().
109-111: Appropriate member variable declarations for iterator functionalityThe member variables
m_schema_tree_node,m_child_schema_tree_nodes, andm_child_schema_tree_node_itare appropriately declared to support iteration over child nodes.
192-204: Accurate type matching innode_type_matches_value_typefunctionThe function effectively ensures that the schema node types match the corresponding value types, enhancing type safety during serialization.
243-245: Clear justification for usingget_parent_id_unsafe()The comments explain that since the node is confirmed not to be the root, using
get_parent_id_unsafe()is safe and avoids redundant checks.

27-33: LGTM: Improved function naming and documentation.The changes to the
check_non_root_nodefunction (formerlycheck_node) are appropriate:
- The new name better reflects the function's purpose.
- The updated documentation clearly describes the function's behaviour.

45-71: LGTM: Comprehensive node validation implemented.The new implementation of
check_non_root_nodesignificantly improves the validation process:
- It checks for the existence and correctness of the node ID.
- It verifies that the node is not a root node.
- It ensures that non-root nodes have a parent ID.
- It compares the node's properties with those specified in the locator.
These changes align well with the PR objectives and enhance the robustness of the schema tree validation.
Consider a minor improvement for better error handling:

98-208: Excellent addition of theNodeclassThe introduction of the
Nodeclass significantly improves the encapsulation and representation of schema tree nodes. The use ofstd::optional<id_t>for the parent ID elegantly solves the issue of representing the root node. The factory methods ensure proper initialization, and the class provides a clear interface for node operations.Consider adding a
static_assertto ensure that theid_ttype is large enough to represent all possible node IDs:static_assert(std::numeric_limits<id_t>::max() >= std::numeric_limits<size_t>::max(), "id_t must be large enough to represent all possible node IDs");This assertion would help prevent potential overflow issues if the schema tree grows very large.

254-288: Well-executed updates toSchemaTreemethod signaturesThe changes to the method signatures in the
SchemaTreeclass are consistent with the newNodeclass implementation. The use ofNode::id_tandNode const&ensures type consistency throughout the class. The addition of theget_root()method provides a convenient way to access the root node directly.Consider adding a
[[nodiscard]]attribute to theget_root()method to encourage proper usage of the returned value:[[nodiscard]] auto get_root() const -> Node const& { return m_tree_nodes[cRootId]; }This addition would align with the usage of

SchemaTree::Node::Type::Nullfor consistency in type checks.- Clarification needed on the new implementation of
cRootIdin theSchemaTreeclass.- Verification of any remaining uses of
SchemaTreeNodein the file.These changes contribute to improved encapsulation and consistency in the codebase.

1-1: LGTM: Removed unused using declarationThe removal of
using clp::ffi::SchemaTreeNode;is consistent with the changes to useSchemaTree::Nodeinstead ofSchemaTreeNodethroughout the file. This cleanup helps maintain code clarity and removes unused declarations.To ensure completeness, let's verify that there are no remaining uses of
SchemaTreeNodein this file.#!/bin/bash # Search for any remaining uses of SchemaTreeNode in the file rg 'SchemaTreeNode' components/core/tests/test-ffi_KeyValuePairLogEvent.cpp
267-267: LGTM: Updated root ID reference, but clarification neededThe change from
cRootIdtoSchemaTree::cRootIdis consistent with the updated schema tree implementation. However, it's not clear from this change alone whethercRootIdis now a function or a static member of theSchemaTreeclass.Could you please clarify the new implementation of
cRootIdin theSchemaTreeclass? Is it a function, a static member, or something else? This information would help in understanding the design choice and ensuring proper usage throughout the codebase.components/core/src/clp/ffi/ir_stream/Serializer.cpp (9)
46-49: Constructor Parameter Type Updated CorrectlyThe parameter type in the
MsgpackMapIteratorconstructor has been appropriately updated toSchemaTree::Node::id_t, aligning with the new schema tree node implementation.
55-57: Return Type ofget_schema_tree_node_idUpdatedThe return type of
get_schema_tree_node_id()is correctly changed toSchemaTree::Node::id_t, ensuring consistency with the updated schema node types.
73-75: Member Variable Type UpdatedThe member variable
m_schema_tree_node_idnow usesSchemaTree::Node::id_t, which reflects the updated node type structure.
85-87: Function Return Type Updated to OptionalThe function
get_schema_tree_node_type_from_msgpack_valnow returnsoptional<SchemaTree::Node::Type>, which is appropriate given that not all MessagePack values may correspond to a schema tree node type.
149-173: Switch Statement Updated with New Node TypesThe switch statement in
get_schema_tree_node_type_from_msgpack_valcorrectly maps MessagePack types to the updatedSchemaTree::Node::Typeenumeration.

422-426: Serialization Function Parameter UpdatedThe
serialize_keyfunction parameter is correctly updated toSchemaTree::Node::id_t. This ensures consistency with the updated schema node ID types.
Line range hint
438-481: Updatedserialize_valFunction with New Node TypesThe
serialize_valfunction now usesSchemaTree::Node::Typeand the switch cases have been updated accordingly. The serialization logic for different node types appears to be accurate and aligns with the new schema definitions.
518-529: Explicit Template Instantiations UpdatedThe explicit template instantiations for
serialize_keyandserialize_valhave been updated to useSchemaTree::Node::id_tandSchemaTree::Node::Type. This change is consistent with the updated node structure.
383-400:⚠️ Potential issueEnsure Proper Handling of Optional
parent_idThe code assumes that
parent_idis always present, but with the change tostd::optional<id_t>, there is a possibility thatparent_idis empty (particularly for the root node). The current implementation does not check ifparent_idhas a value before using it, which may lead to undefined behaviour.Please modify the code to handle the optional nature of
parent_id. Here is a suggested fix:auto const parent_id_optional{locator.get_parent_id()}; if (parent_id_optional.has_value()) { auto const parent_id = parent_id_optional.value(); if (parent_id <= UINT8_MAX) { m_schema_tree_node_buf.push_back(cProtocol::Payload::SchemaTreeNodeParentIdUByte); m_schema_tree_node_buf.push_back(bit_cast<int8_t>(static_cast<uint8_t>(parent_id))); } else if (parent_id <= UINT16_MAX) { m_schema_tree_node_buf.push_back(cProtocol::Payload::SchemaTreeNodeParentIdUShort); serialize_int(static_cast<uint16_t>(parent_id), m_schema_tree_node_buf); } else { // Out of range return false; } } else { // Handle the case where there is no parent ID (e.g., root node) m_schema_tree_node_buf.push_back(cProtocol::Payload::SchemaTreeNodeNoParentId); }This adjustment checks for the presence of
parent_idand handles the root node appropriately.⛔ Skipped due to learnings

Description
In the current implementation, each ffi schema tree node stores an ID to keep track of the parent node ID. However, this scheme doesn't make sense for the root node since the root, by definition, should have no parent. In the current implementation, we manually set the parent ID of the root to itself (which is 0).
This PR changes the underlying parent ID from
id_ttostd::optional<id_t>so the parent ID can be null. This scheme allows us to implement the root properly by setting its parent ID to null. After this change, there are two standard approaches to identifying whether a node is a root:SchemaTree, it is identified as the root.We then made the following changes according to these two root identifications:
Notice that either of these approaches is valid if and only if the root is unique in a schema tree. It is the schema tree's responsibility to ensure the root's validity and uniqueness. We secured this with the following design:
SchemaTreeNodeis instantiated using factory functions. There are two factory functions: one for the root node and one for non-root nodes. The constructed node should be either a root node or a non-root node.SchemaTreecalls the root node factory functions to create the root as its first node (ID 0) on initialization. The root factory function must not be called elsewhere.SchemaTreeinserts new nodes to the tree identified by a valid node locator. Since the node locator specifies a parent ID, conceptually, the node created by such a locator must be a non-root node.To achieve this design, we move
SchemaTreeNodeinto the schema tree class asSchemaTree::Node, so that it can accessSchemaTree::cRootIdandSchemaTree::NodeLocator(to implement bullet point 2 and 3 above) without circular dependency. The factory functions and constructors of the node class are made private.SchemaTreeis marked asfriendto ensure it is the only class that can instantiate tree nodes.We update the schema tree unit test to ensure that each build meets the assumptions above in case future development on the schema tree breaks them.
