📄 Auth.to_header() in sentry_sdk/utils.py

📈 Performance improved by 30% (0.30x faster)

⏱️ Runtime went down from 82.2 microseconds to 63.0 microseconds

Explanation and details

In the provided Python program, the initialization and the to_header method look fairly simple and straightforward. One area that might benefit minimally in terms of micro-optimizations is the string concatenation and formatting within the to_header method. However, the gains may be relatively small unless the method is called extremely frequently.

Here's the optimized version of the code.

Key Changes.

  1. String Concatenation:
    • Use f-strings instead of the % operator, which can be slightly more efficient and readable.
  2. List Comprehension in join:
    • Use list comprehension for the join method, which can be marginally faster and more Pythonic.

These changes optimize the to_header method for potentially small performance gains in string handling and comprehension. The rest of the class is already optimized as it simply initializes the object properties.

Correctness verification

The new optimized code was tested for correctness. The results are listed below.
