280-399: Check for null pointer afterdynamic_pointer_cast.
IngetPatchData_(line 393 onward), the cast totypename ViewInfo::patch_data_typeis unverified. If the variable is incorrectly registered, the cast could fail and result in anullptrdereference at->getPointer(). Consider handling a null result before callinggetPointer().std::shared_ptr<typename ViewInfo::patch_data_type> data = std::dynamic_pointer_cast<typename ViewInfo::patch_data_type>(patchData); -if (!data) // might be null if cast fails - return data->getPointer(); +if (!data) { + // handle error or throw +} +return data->getPointer();tests/amr/resources_manager/test_resources_manager.cpp (2)

12-24: Revise pricing logic to ensure discounts remain beneficial.The current implementation has a potential issue where adding a flat $20 fee after applying the discount can result in a higher final price than without a discount, especially for smaller purchases. For example:
- $100 purchase with 10% discount = $90 + $20 fee = $110 (more than original price)
This could lead to customer dissatisfaction and defeat the purpose of the loyalty program.
Would you like me to propose an alternative implementation that ensures discounts always benefit the customer?
Line range hint
4-9: Fix incorrect test assertion.The test assertion is incorrect. For a $100 purchase with 15% senior loyalty discount:
- Discounted amount: $100 * (1 - 0.15) = $85
- Final amount with fee: $85 + $20 = $105
Apply this fix:
- self.assertEqual(result, 80, "Senior loyalty discount not applied correctly") + self.assertEqual(result, 105, "Senior loyalty discount not applied correctly")

src/amr/resources_manager/resources_manager.hpp (2)
141-226: Consider updating documentation to reflect the new naming convention.
Several comments (e.g., lines 141–147) still refer to “ResourcesViews”. Since the code now uniformly uses “View,” it would be clearer if doc comments matched this terminology.
Line range hint
234-279: Observe potential scaling concerns with time retrieval.
ThegetTimesandsetTimemethods iterate over all patch data IDs. For very large systems, performance could degrade. Caching or chunking strategies may be helpful if iteration must scale.src/amr/resources_manager/resources_guards.hpp (1)
52-61: Favor explicit default moves only if needed.
While defaulting move operations is often fine, confirm that no special resource cleanup logic is required during move operations.tests/amr/resources_manager/test_resources_manager.hpp (1)
32-33: Consider adding documentation for type aliases.The type aliases are well-structured, but adding documentation would improve code maintainability.

src/amr/resources_manager/resources_manager.hpp (3)
73-96: Clarify dimension and interpolation order types in meta structures.
WhileViewMetaWithParticlesandViewMetaMeshOnlycorrectly derive the dimension and interpolation order fromGridLayoutT, it would be prudent to ensure that any downstream usage (e.g., inResourcesManager) consistently treatsdimensionas a non-boolean type (likestd::size_t). A mismatch, such as declaring it asboolin the derived class, may lead to subtle compilation issues or incorrect behavior.
98-125: Confirm the enum naming ofResource_tand usage inResourcesInfo.
IntroducingResource_tto distinguish field vs. particle resources is a neat approach. Please ensure all references elsewhere (such as in the “ViewInfoResolver” or user code) use these enum values properly.
Line range hint
408-527: Validate the runtime errors inregisterResource_().
Ifview.name()is not guaranteed to be unique, you risk collisions. If it is unique, consider documenting that requirement explicitly.src/amr/resources_manager/particle_resource.hpp (1)
12-22: No major concerns; the template structure is consistent.
ParticleViewInfocleanly maps the resource to variable and patch data types. Ensure all references toParticleResource::dimensionremain consistent, especially if combined with multi-dimensional systems.src/amr/resources_manager/resources_guards.hpp (2)
18-34: Confirm thread-safety of resource pointer assignment.
The constructor immediately sets resources by callingsetResources_on all provided views. In a concurrent environment, ensure no data races occur if multipleViewGuards or patches are set simultaneously.
40-46: Destructor usage appears correct.
Resetting view buffers tonullptrensures that references to patch data do not escape the guard's scope. This is an elegant approach to RAII for resource handles.tests/amr/resources_manager/test_resources_manager.hpp (2)

72-102: Consider adding static assertions for template parameters.The template structures
ViewMetaWithParticlesandViewMetaMeshOnlycould benefit from compile-time validation of their template parameters.Add static assertions to validate template parameters:
template<typename GridLayoutT, typename GridView_t, typename ParticleView_t> struct ViewMetaWithParticles { + static_assert(GridLayoutT::dimension > 0, "GridLayoutT must have positive dimension"); + static_assert(GridLayoutT::interp_order > 0, "GridLayoutT must have positive interpolation order"); static constexpr std::size_t dimension = GridLayoutT::dimension; static constexpr std::size_t interp_order = GridLayoutT::interp_order;
104-125: Consider adding noexcept specifications.The ResourcesManager class inherits from Super but doesn't specify exception specifications. In modern C++, it's good practice to explicitly declare noexcept for move operations and destructors.
Add noexcept specifications:
- ResourcesManager(ResourcesManager&&) = delete; + ResourcesManager(ResourcesManager&&) noexcept = delete; - ResourcesManager& operator=(ResourcesManager&&) = delete; + ResourcesManager& operator=(ResourcesManager&&) noexcept = delete; - ~ResourcesManager() + ~ResourcesManager() noexcept

🛠️ Refactor suggestion
Enhance type safety in registerResource_ method.
The type checking for Resource_t could be made more robust using type traits instead of direct type comparison.
Consider refactoring to use type traits:
- if constexpr (std::is_same_v<View, GridView_t>)
+ if constexpr (traits::is_grid_view_v<View>)
{
info.type = Resource_t::Field;
}
- else if constexpr (std::is_same_v<View, ParticleView_t>)
+ else if constexpr (traits::is_particle_view_v<View>)
{
info.type = Resource_t::Particle;
}
+ else
+ {
+ static_assert(always_false_v<View>, "Unsupported view type");
+ }Committable suggestion skipped: line range outside the PR's diff.

333-350:⚠️ Potential issueIncomplete implementation in makeAllViews method.
The method iterates over the hierarchy but doesn't perform any meaningful operation. The commented-out code at line 346 suggests incomplete implementation.
Please either:
- Complete the implementation by uncommenting and fixing the code at line 346
- Remove the method if it's not needed
- Add a TODO comment explaining what needs to be implemented
393-400:⚠️ Potential issueAdd nullptr check for dynamic_pointer_cast.
The dynamic_pointer_cast could return nullptr, which would lead to undefined behavior.
Apply this fix:
auto getPatchData_(ResourcesInfo const& resourcesVariableInfo, SAMRAI::hier::Patch const& patch) const { auto patchData = patch.getPatchData(resourcesVariableInfo.variable, context_); - return (std::dynamic_pointer_cast<typename ViewInfo::patch_data_type>(patchData)) - ->getPointer(); + auto typedData = std::dynamic_pointer_cast<typename ViewInfo::patch_data_type>(patchData); + if (!typedData) { + throw std::runtime_error("Failed to cast patch data to required type"); + } + return typedData->getPointer(); }

459-480: Consider using type traits for more robust type checking.The current implementation uses direct type comparison. Using type traits would make the code more maintainable and extensible.
Consider this enhancement:
template<typename View> void registerResource_(View const& view) { using ViewInfoResolver_t = ViewInfoResolver<This, View>; if (nameToResourceInfo_.count(view.name()) == 0) { ResourcesInfo info; info.variable = ViewInfoResolver_t::make_shared_variable(view); info.id = variableDatabase_->registerVariableAndContext( info.variable, context_, SAMRAI::hier::IntVector::getZero(dimension_)); - if constexpr (is_field_v<View>) + if constexpr (traits::is_grid_view_v<View>) { info.type = Resource_t::Field; } - else if constexpr (is_particles_v<View>) + else if constexpr (traits::is_particle_view_v<View>) { info.type = Resource_t::Particle; } + else + { + static_assert(always_false_v<View>, "Unsupported view type"); + } nameToResourceInfo_.emplace(view.name(), info); } }

70-102: Well-structured type definitions with clear separation of concerns!The new template structures provide a clean separation between particle and mesh-only views, with appropriate use of static constexpr members and clear type aliases.
104-125: Clean class hierarchy with improved type safety!The ResourcesManager's inheritance from SuperDispatcher and the addition of the Resource_t enum class enhance type safety and maintainability. The ResourcesInfo struct's new type field provides better resource categorization.

45-57: Consider extracting the lambda to a named function.The lambda function contains significant logic for registering and allocating resources. Consider extracting it to a named member function for better readability and reusability.

391-421: Consider breaking down makeAllViews into smaller functions.The makeAllViews method is quite long and handles multiple responsibilities. Consider extracting the view creation logic into separate functions for fields and particles.

542-549: Consider using a switch statement for resource type assignment.The if-else chain for resource type assignment could be more maintainable using a switch statement with compile-time type traits.
- if constexpr (is_field_v<View>) - { - info.type = Resource_t::Field; - } - else if constexpr (is_particles_v<View>) - { - info.type = Resource_t::Particle; - } + constexpr auto resource_type = []() { + if constexpr (is_field_v<View>) + return Resource_t::Field; + else if constexpr (is_particles_v<View>) + return Resource_t::Particle; + else + static_assert(always_false_v<View>, "Unsupported view type"); + }(); + info.type = resource_type;

14-15: LGTM! Clean template structure definition.The renaming from
UserParticleTypetoParticleViewInfoand the template parameter change improve clarity by better expressing the intent.
20-22: Consider implementing the suggested templating improvement.The TODO comment suggests potential improvements to the template structure. Consider implementing this enhancement to make the link to ParticlePack more flexible.
Would you like me to propose an implementation for this improvement?
tests/amr/resources_manager/test_resources_manager.hpp (2)
28-29: LGTM! Clear test class structure.The renaming from
aResourceUserCollectiontoViewCollectionimproves clarity and aligns with the new terminology.
34-35: LGTM! Proper type definition with particle support.The ResourcesManager type now correctly includes ParticleArray support, making it more flexible.
src/amr/resources_manager/resources_manager.hpp (2)
26-74: LGTM! Well-structured HierarchyViews implementation.The HierarchyViews class provides a clean implementation for managing views across different levels, with proper error checking and clear member functions.
465-472:⚠️ Potential issueAdd null pointer check in getResourcesPtr_ method.
The dynamic pointer cast could return nullptr, but this case isn't handled.
template<typename ViewInfo> auto getResourcesPtr_(ResourcesInfo const& resourcesVariableInfo, SAMRAI::hier::Patch const& patch) const { auto patchData = patch.getPatchData(resourcesVariableInfo.variable, context_); - return (std::dynamic_pointer_cast<typename ViewInfo::patch_data_type>(patchData)) - ->getPointer(); + auto typedData = std::dynamic_pointer_cast<typename ViewInfo::patch_data_type>(patchData); + if (!typedData) { + throw std::runtime_error("Failed to cast patch data to required type"); + } + return typedData->getPointer(); }Likely invalid or redundant comment.
