…#26 (`clean_concolic_tests`)

To optimize the `AssertCleanup` class, we can improve the `_transform_assert_line` method by reducing the use of regular expressions, and replacing them with more efficient string operations where possible. Where regular expressions are still necessary, we compile them once and reuse them. Here's the refactored code.



### Explanation of Changes.
1. **Regex Compilation in `__init__`**: Compiled the regular expressions in the `__init__` method to avoid recompiling them every time `_transform_assert_line` is called, improving speed.

2. **String Operations for Trailing Characters**: Replaced `re.sub` used to strip trailing commas or semicolons with simpler string operations, improving efficiency.

These improvements help in optimizing the running speed of the program while maintaining the same functionality.

To optimize the given code, we should focus on reducing redundant operations and improving the performance of regular expression matching, string manipulation, and list operations. Let's break down the changes.

### Key Optimizations.

This results in a more efficient and potentially faster code execution while maintaining the same functionality and output structure.

📝 Explanation and details

To optimize the given program, we need to improve the performance of regex operations and the argument splitting functionality.

  • Use re.compile for regex patterns, as compiling them once and reusing can improve performance.
  • Optimize the _split_top_level_args function for better performance by avoiding unnecessary checks and operations inside the loop.

Explanation of Improvements.

  1. Compiled Regular Expressions:

    • Compile the regular expressions assert_pattern and unittest_pattern in the __init__ method to avoid recompiling them multiple times.
  2. _split_top_level_args Optimization.

    • Removed unnecessary current.append(char) for commas in the top-level context and optimized the logic by keeping all current.append(char) calls outside the conditions.
    • It ensures that characters are added to current only when needed, avoiding extra operations especially in deeply nested arguments.

⚡️ Codeflash found optimizations for this PR

📄 28% (0.28x) speedup for AssertCleanup.transform_asserts in codeflash/code_utils/code_replacer.py

⏱️ Runtime : 1.93 millisecond 1.51 millisecond (best of 714 runs)

📝 Explanation and details

Sure, here is a possible optimized version of the provided Python code:

Optimizations.

  1. Joining in One-Liner: In the transform_asserts function, replaced the multiline for-loop with a one-liner using a generator expression. This reduces the overhead of method calls and joining strings.
  2. Regex Optimization:
    • Combined ; and , in one regex rstrip call for removing trailing commas and semicolons.
  3. String Handling:
    • Removed stripping in self._split_top_level_args which provided no performance gain and added it when necessary.
    • Moved the common strip operation to a single logical place to ensure no redundant calls.

Note.

The major improvements made are focused on reducing redundant operations and enhancing readability without increasing the computational cost. This will make the program slightly faster with cleaner operations while maintaining the original logic and functionality.

📄 22% (0.22x) speedup for clean_concolic_tests in codeflash/code_utils/code_replacer.py

⏱️ Runtime : 12.8 milliseconds 10.5 milliseconds (best of 234 runs)

📝 Explanation and details

To optimize the provided Python program for faster execution, you can make a few improvements by avoiding redundant parsing, reducing unnecessary operations, and optimizing the existing code structure.

We can first optimize the clean_concolic_tests function by removing the redundant AST parsing and fixing the unnecessary traversal of the AST when possible.

Here's the optimized version.

Key Optimization Changes.

  1. Avoiding Double ast.parse: The original implementation was parsing the test suite code twice, once for checking if it can parse and another for actual processing. I've eliminated the redundant parsing.
  2. Pattern Matching Performance: Using the new pattern matching syntax (:=) introduced in Python 3.8 to compactly perform regex matches inside conditional statements. This reduces the overall complexity and improves readability.
  3. Return Original Line if No Match: In _transform_assert_line, if no transformation is applied by the regex matches, return the original line directly without a secondary check in the transform_asserts function.

Overall, the optimized code eliminates unnecessary steps and focuses directly on the critical paths, enhancing the performance and readability of the program.

⚡️ Codeflash found optimizations for this PR

📄 21% (0.21x) speedup for AssertCleanup._split_top_level_args in codeflash/code_utils/code_replacer.py

⏱️ Runtime : 2.09 milliseconds 1.73 millisecond (best of 511 runs)

📝 Explanation and details

Here is an optimized version of your Python program. The changes include a streamlined for-loop with combined conditions to reduce checks and appending operations.

Changes made.

  1. Introduced a dictionary char_to_depth_change to replace the repeated if char in ... checks with a single dictionary lookup. This reduces the number of condition checks needed for characters affecting the depth value.
  2. Consolidated depth adjustments and current appending into single lines inside the loop to streamline operations and reduce overall processing time.

…(`clean_concolic_tests`)

Here is the optimized version of the given Python program. The program is optimized to run faster by pre-compiling regular expressions, avoiding repetitive function calls, and streamlining string manipulations.



### Explanation of Optimizations
1. **Pre-compiling Regular Expressions**: 
   - `re.compile` is used to pre-compile the regular expressions when the class is initialized, which speeds up the `_transform_assert_line` method by avoiding the need to compile the same patterns multiple times.

2. **Avoiding Repetitive Function Calls**.
   - The `append` method of lists is resolved once and assigned to a variable before entering the loop in `_split_top_level_args`. This avoids the cost of repeatedly resolving the method during each iteration of the loop.

3. **Streamlined String Manipulations**.
   - Instead of using `strip` and `re.sub` together, simplified `rstrip` with the specified characters is used to achieve the same effect with lesser overhead.

These changes contribute to small performance improvements, which can add up for larger codebases or more intensive usage scenarios.

…26 (`clean_concolic_tests`)

- **Explanation**: 
  - We optimize the character check by using a dictionary, `delimiters`, that maps each character to its corresponding depth adjustment value. This avoids multiple `if-elif` statements and performs a single dictionary lookup.
  - The loop iterates through each character once, providing an efficient way to split the args string. The overall logic and output remain unchanged.

⚡️ Codeflash found optimizations for this PR

📄 39% (0.39x) speedup for AssertCleanup._transform_assert_line in codeflash/code_utils/concolic_utils.py

⏱️ Runtime : 367 microseconds 264 microseconds (best of 354 runs)

📝 Explanation and details

Here's the optimized version of the Python program. The main focus was on optimizing the regular expressions and the if conditions. Some parts of string processing were also simplified.

…concolic_tests`)

To optimize the program for better performance, consider the following approaches.

1. **Batch Processing**: Instead of transforming the asserts line-by-line within the loop, we can accumulate assert lines and process them in bulk.
2. **Efficient String Operations**: Minimize the number of string operations and regular expression matching by using direct AST manipulation.
3. **Optimizing AST Walk**: Handle the bulk processing of relevant AST nodes within the single pass over the tree.

Here's the optimized version.



### Changes Made.
1. **Efficient String Handling**: Optimized `_transform_assert_line()` by reducing redundant operations.
2. **Batch Processing**: The `transform_asserts()` function processes lines in one pass and transformed lines in bulk at the end.
3. **AST Optimization**: A single subclass of `ast.NodeTransformer` (`AssertTransform`) handles both `Assert` and `FunctionDef` node transformations in one traversal.

These changes improve readability and maintainability while also boosting the performance by reducing the complexity of operations performed per line and reusing parsing results effectively.
