test/container/TAlgorithmTest.cpp (1)
13-27: Enhance test coverage with additional test cases.Consider adding test cases for:
- Empty array
- Single element array
- Invalid iterator combinations
+TEST_F(TAlgorithmTest, distanceEmptyTest) { + TArray<float> theArray; + size_t dist = distance(theArray.begin(), theArray.end()); + EXPECT_EQ(dist, 0u); +} + +TEST_F(TAlgorithmTest, distanceSingleElementTest) { + TArray<float> theArray; + theArray.add(1.0f); + size_t dist = distance(theArray.begin(), theArray.end()); + EXPECT_EQ(dist, 1u); +}include/cppcore/Container/TAlgorithm.h (2)
29-34: Improve documentation for the distance function.The documentation should specify:
- Requirements for the iterator type (e.g., random access)
- Behavior for invalid iterator combinations
- Return value semantics
-/// @brief Function to calulate the distance between two iterators. -/// @tparam TIt The container iterator -/// @param begin The first container iterator -/// @param end The second container iterator -/// @return The distance between the two iterators. +/// @brief Calculates the distance between two iterators. +/// @tparam TIt The iterator type (must support random access) +/// @param begin The first iterator position +/// @param end The second iterator position +/// @return The number of elements between begin and end +/// @note Requires random access iterators that support subtraction +/// @pre begin must be less than or equal to end
35-39: Consider relaxing the iterator order assertion.The current assertion requires
begin < end, which might be too restrictive. For bidirectional iterators, you might want to allowbegin == end.template<class TIt> inline size_t distance(TIt begin, TIt end) { - assert(begin < end); + assert(begin <= end); const size_t distance = end - begin; return distance; }

103-106: LGTM! Member variable renaming improves consistency.The renaming of member variables from
m_*tom*format aligns with modern C++ naming conventions. The initialization and cleanup in constructors and destructor are properly implemented.Consider using
std::unique_ptrformPoolto leverage RAII and automatically handle memory cleanup:-T *mPool; +std::unique_ptr<T[]> mPool; -mPool = new T[mPoolsize]; +mPool = std::make_unique<T[]>(mPoolsize); -delete[] mPool; +// No explicit deletion needed with unique_ptrAlso applies to: 109-112, 117-122, 125-125
include/cppcore/Container/TStaticArray.h (3)
83-86: Consider initializing array elements in default constructor.The default constructor only initializes
mLenbut leaves array elements uninitialized, which could lead to undefined behavior if accessed before assignment.Consider initializing array elements to a default value:
template <class T, size_t len> inline TStaticArray<T, len>::TStaticArray() : mLen(len) { - // empty + std::fill_n(mArray, len, T()); }
94-100: Optimize copy constructor using std::copy.The manual loop in the copy constructor can be replaced with
std::copyfor better performance and readability.template <class T, size_t len> inline TStaticArray<T, len>::TStaticArray(const TStaticArray<T, len> &rhs) : mLen(rhs.mLen) { - for (size_t i = 0; i < mLen; ++i) { - mArray[i] = rhs.mArray[i]; - } + std::copy(rhs.mArray, rhs.mArray + len, mArray); }
109-114: Consider renamingmemsetto avoid confusion with C's memset.The method name
memsetcould be misleading as it's not using C'smemset. Consider a more descriptive name likefillWithorsetAll.template <class T, size_t len> -inline void TStaticArray<T, len>::memset(T value) { +inline void TStaticArray<T, len>::fillWith(T value) { for (size_t i = 0; i < mLen; ++i) { mArray[i] = value; } }

139-142: LGTM! Member variable initialization is safe and consistent.The member variables are properly renamed and safely initialized to prevent undefined behavior.
Also applies to: 147-150, 156-159
171-184: Add nullptr check for mPool in alloc method.The

258-278: Validate growth size in resize method.The resize method should ensure the growth size is not zero to prevent allocation of empty pools.
Add size validation:

template <class T> inline void TPoolAllocator<T>::dumpAllocations(std::string &allocs) { allocs.clear(); allocs += "Number allocations = "; + if (mCurrent == nullptr) { + allocs += "0"; + } else { allocs += std::to_string(mCurrent->mCurrentIdx); + } allocs += "\n"; }include/cppcore/Memory/TDefaultAllocator.h (2)
40-40: LGTM! Good use of modern C++ features.Using
= defaultfor the constructor explicitly indicates the intent to use compiler-generated implementation, which is appropriate for this allocator class. This change aligns with modern C++ best practices.
43-43:✅ Verification successful
LGTM! Proper memory management pattern.
Using
= defaultfor the destructor is correct as memory cleanup is handled explicitly through thereleasemethod. The class correctly follows RAII principles by delegating memory management to the container classes.Let's verify that memory management is handled correctly in the container classes that use this allocator:
🏁 Script executed:
#!/bin/bash # Description: Check for memory management in container classes using TDefaultAllocator # Search for container classes using TDefaultAllocator rg -A 5 "TDefaultAllocator" --type cpp # Search for proper memory cleanup in destructors ast-grep --pattern 'class $_ { $$$ ~$_() { $$$ } $$$ }'Length of output: 7270
Approval: Memory Management Verified in TDefaultAllocator
- The change to use
~TDefaultAllocator() = default;is appropriate since memory cleanup is handled explicitly through thereleasemethod.- Container classes (e.g., TQueue, THashMap, TList, and TArray) that use this allocator do not require additional destructor logic in the allocator.
- The class design correctly adheres to RAII principles, enabling container classes to manage memory properly.
LGTM!

The member variable reference update is consistent with previous changes. Let's verify that this naming convention is consistently applied across the codebase.

Action: Verify Consistent Naming Convention for Member Variables
The update from
m_typetomTypeappears correctly implemented and consistent with previous changes. However, the initial verification script encountered errors due to the unsupported file type flag (hpp). To ensure thorough verification, please run an updated search using a glob pattern instead. For example:#!/bin/bash echo "Checking for any remaining instances of old naming convention (m_type)..." rg "m_type" --glob "*.cpp" --glob "*.hpp" --glob "*.h" echo "Verifying consistency of new naming convention (mType)..." rg "mType" --glob "*.cpp" --glob "*.hpp" --glob "*.h"If these searches confirm that no traces of the old naming style remain, you can confidently consider this change approved. Please verify the outputs manually.

97-107: LGTM! Consider enhancing test coverage.The basic copy test is a good start, but could be strengthened with additional test cases.
Consider adding the following test scenarios:
- Verify deep copy by modifying source array after copy
- Test with different values per element
- Test with different data types (e.g., custom objects)
Example enhancement:
TEST_F(TStaticArrayTest, copyDeepTest) { TStaticArray<int, 4> arr; for (size_t i = 0; i < 4; ++i) { arr[i] = i; // Different values } TStaticArray<int, 4> copy_arr = arr; // Modify source array arr[0] = 99; // Verify deep copy (copy_arr should be unchanged) EXPECT_EQ(0, copy_arr[0]); for (size_t i = 1; i < 4; ++i) { EXPECT_EQ(i, copy_arr[i]); } }

🧩 Analysis chain
Enhance test coverage and handle memory management.
The current test only verifies that the pointer is non-null. Consider:
- Testing actual disk space values
- Handling memory management of the returned pointer
- Making the test platform-independent
Here's a more comprehensive test implementation:
-TEST_F(FileSystemTest, getFreeDiskSpaceTest) {
- FileSystem fs("c:\\");
- FSSpace *space = fs.getFreeDiskSpace();
- EXPECT_NE(space, nullptr);
-}
+TEST_F(FileSystemTest, getFreeDiskSpaceTest) {
+ FileSystem fs(GetTestPath());
+ FSSpace *space = fs.getFreeDiskSpace();
+ ASSERT_NE(space, nullptr);
+
+ // Verify disk space values are reasonable
+ EXPECT_GT(space->TotalSpace, 0);
+ EXPECT_GE(space->FreeSpace, 0);
+ EXPECT_LE(space->FreeSpace, space->TotalSpace);
+
+ // Clean up
+ delete space;
+}Additionally, consider adding test cases for:
- Invalid paths
- Network paths
- Removable drives
Let me verify the FSSpace structure and memory ownership:
🏁 Script executed:
#!/bin/bash
# Search for FSSpace definition and memory management patterns
rg -A 5 "struct.*FSSpace" .
rg "getFreeDiskSpace.*\(" .Length of output: 685
Action Required: Update FSSpace field references and enhance test coverage
The suggested diff snippet should be updated to reflect the actual fields of the FSSpace structure—instead of using TotalSpace and FreeSpace, it should use capacity and free. Additionally, the test should continue to improve platform independence and memory management, while considering additional edge cases such as invalid paths, network paths, and removable drives.
Suggested updates:
- Replace the hard-coded
"c:\\"with a platform-independent path (e.g., using a helper such asGetTestPath()). - Verify the disk space values using the correct fields:
- Use
EXPECT_GT(space->capacity, 0); - Use
EXPECT_GE(space->free, 0); - Use
EXPECT_LE(space->free, space->capacity);
- Use
- Ensure proper memory cleanup by deleting the allocated pointer.
- Consider adding additional test cases for scenarios like invalid paths, network paths, and removable drives.
Rewritten diff snippet:
-TEST_F(FileSystemTest, getFreeDiskSpaceTest) {

- FSSpace *space = fs.getFreeDiskSpace();
- EXPECT_NE(space, nullptr);

Improve test robustness and cross-platform compatibility.
The current test implementation has several issues:
- Hard-coded Windows path won't work on other platforms
- Potential memory leak as the space pointer isn't freed
- Minimal validation of the returned data
Here's a suggested improvement:
TEST_F(FileSystemTest, getFreeDiskSpaceTest) {
- FileSystem fs("c:\\");
+ // Use platform-independent path
+#ifdef _WIN32
+ const char* testPath = "C:\\";
+#else

Return type of data() method needs improvement.
The method should return a const T* for const-correctness when the container is const-qualified.
Apply this diff to improve const-correctness:
- T *data() const;
+ const T* data() const;
+ T* data() { return mData; }Also applies to: 491-493

Same issue with allocation size in the reallocation code.
The allocation size is incorrectly multiplied by sizeof(T) in the reallocation code as well.
Apply this diff to fix the allocation:
- mData = mAllocator.alloc(size * sizeof(T));
+ mData = mAllocator.alloc(size);📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Incorrect size calculation in memory allocation.
The allocation size is incorrectly multiplied by sizeof(T) in the resize method, but the allocator already handles the type size.

Potential integer overflow in capacity calculation.
The capacity calculation in the move operation could potentially overflow for large arrays.
Apply this diff to prevent integer overflow:
- const size_t numElements = mSize - fromIdx;
- const size_t newSize = toIdx + numElements;
- while (mCapacity < newSize) {
- resize(mCapacity + Details::getGrowing(newSize - mCapacity));
+ if (fromIdx > mSize) {
+ return; // Invalid fromIdx
+ }
+ const size_t numElements = mSize - fromIdx;
+ if (toIdx > std::numeric_limits<size_t>::max() - numElements) {
+ throw std::overflow_error("Array size would overflow");

443-451: Consider optimizing linear search for sorted arrays.While the linear search implementation is correct, consider adding an optional binary search implementation for sorted arrays to improve performance for large datasets.
Apply this diff to add binary search capability:
+ /// @brief Performs a binary search for a given item in a sorted array. + /// @param[in] item The item to look for. + /// @return An iterator showing to the position will be returned. + /// @note The array must be sorted for binary search to work correctly. + Iterator binarySearch(const T& item) { + if (isEmpty()) { + return end(); + } + + size_t left = 0; + size_t right = mSize - 1; + + while (left <= right) { + size_t mid = left + (right - left) / 2; + if (mData[mid] == item) { + return &mData[mid]; + } + if (mData[mid] < item) { + left = mid + 1; + } else { + if (mid == 0) break; + right = mid - 1; + } + } + + return end(); + }
202-206: Consider using std::copy for better performance in copy constructor.The manual loop in the copy constructor could be replaced with std::copy for potentially better performance.
Apply this diff to use std::copy:
