Walkthrough

The changes in this pull request involve modifications to the global_min and global_max methods in the PatchHierarchy class located in hierarchy.py. The updates replace the standard min() and max() functions with np.nanmin() and np.nanmax() to ensure that NaN values are ignored during calculations. Additionally, error handling in the sim property method has been improved to raise a RuntimeError with a more descriptive message upon deserialization failure.

Changes

File Path Change Summary
pyphare/pyphare/pharesee/hierarchy/hierarchy.py Updated global_min and global_max methods to use np.nanmin() and np.nanmax(). Enhanced error handling in sim property method.

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>, please review it.
    • Generate unit testing code for this file.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit testing code for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
    • @coderabbitai read src/utils.ts and generate unit testing code.

🛠️ Refactor suggestion

Refactor to reduce code duplication with global_min.

The global_max implementation duplicates the logic from global_min. Consider extracting a common utility function to handle both cases.

Here's a suggested refactoring:

+    def _global_minmax(self, qty, operation, time=None):
+        """Helper function for global min/max calculations
+        Args:
+            qty: The quantity to compute min/max for
+            operation: np.nanmin or np.nanmax
+            time: Optional timestamp
+        Returns:
+            The global min or max value
+        Raises:
+            ValueError: If all values are NaN
+        """
+        time = time or self._default_time()
+        values = []
+        for _, lvl in self.levels(time).items():
+            for patch in lvl.patches:
+                values.append(patch.patch_datas[qty].dataset[:])
+        all_values = np.concatenate(values)
+        if np.all(np.isnan(all_values)):
+            raise ValueError("All values are NaN")
+        return operation(all_values)
+
+    def global_min(self, qty, **kwargs):
+        return self._global_minmax(qty, np.nanmin, kwargs.get("time"))
+
+    def global_max(self, qty, **kwargs):
+        return self._global_minmax(qty, np.nanmax, kwargs.get("time"))

This refactoring:

  1. Eliminates code duplication
  2. Improves performance by avoiding repeated array concatenations
  3. Properly handles the all-NaN case
  4. Makes the code more maintainable

🛠️ Refactor suggestion

Consider optimizing the min calculation and handling edge cases.

The current implementation using array concatenation in each iteration is not optimal. Additionally, the case where all values are NaN should be handled explicitly.

Consider this more efficient implementation:

-                    m = np.nanmin(pd.dataset[:])
-                    first = False
-                else:
-                    data_and_min = np.concatenate(([m], pd.dataset[:]))
-                    m = np.nanmin(data_and_min)
+                    m = pd.dataset[:]
+                    first = False
+                else:
+                    m = np.append(m, pd.dataset[:])
+        if np.all(np.isnan(m)):
+            raise ValueError("All values are NaN")
+        return np.nanmin(m)

293-297: Reduce code duplication with global_min.

The implementation duplicates the logic from global_min.

As suggested in a previous review, consider extracting a common utility function to handle both cases. This would:

  1. Eliminate code duplication
  2. Ensure consistent handling of edge cases
  3. Make the code more maintainable

The previous review comment provided a detailed implementation suggestion.

🛠️ Refactor suggestion

Consider optimizing the min calculation and handling edge cases.

While using np.nanmin correctly handles NaN values, the current implementation has some performance concerns:

  1. Concatenating arrays in a loop is inefficient (O(n²) complexity).
  2. No explicit handling for the case where all values are NaN.

Consider this more efficient implementation:

-                    m = np.nanmin(pd.dataset[:])
-                    first = False
-                else:
-                    data_and_min = np.concatenate(([m], pd.dataset[:].flatten()))
-                    m = np.nanmin(data_and_min)
+                    values = pd.dataset[:]
+                    first = False
+                else:
+                    values = np.append(values, pd.dataset[:])
+        if np.all(np.isnan(values)):
+            raise ValueError("All values are NaN")
+        return np.nanmin(values)
