v0.1.6 - Complete Wheel Matrix with Updated cibuildwheel

🎯 What's New in v0.1.6

Fixed Missing Wheels

• Upgraded cibuildwheel from v2.16.2 to v2.22 for full Python 3.13/3.14 support
• Now building ALL Python versions including regular CP313/CP314 and PyPy 3.11

Complete Wheel Matrix

This release should include:

• ✅ CPython 3.10, 3.11, 3.12, 3.13, 3.14 (regular)
• ✅ CPython 3.13t, 3.14t (No-GIL free-threading)
• ✅ PyPy 3.10, 3.11

Installation

# Regular CPython (any version)
pip install pwalk

# Free-threading CPython (No GIL!)
python3.13t -m pip install pwalk
PYTHON_GIL=0 python3.13t your_script.py

# PyPy (JIT-compiled)
pypy3 -m pip install pwalk

What Changed from v0.1.5

• Upgraded cibuildwheel: v2.16.2 → v2.22
• This adds Python 3.13/3.14 support to cibuildwheel
• PyPy 3.11 wheel should now build correctly

Full Changelog: v0.1.5...v0.1.6

v0.1.5 - Fixed Free-Threading Wheel Platform Tags

What's New in v0.1.5

Fixed

• 🔧 Free-threading wheel platform tags - Now uses proper manylinux tags instead of linux_x86_64
• ✅ auditwheel integration - Automatically repairs wheels for PyPI compatibility

What Was Wrong in v0.1.4

PyPI rejected free-threading wheels with error:

Binary wheel has an unsupported platform tag 'linux_x86_64'

The Fix

Added auditwheel repair step to convert wheel tags:

• linux_x86_64 → manylinux_2_17_x86_64
• This is the standard approach for Linux wheel distribution

v0.1.1 - Performance Benchmarks & Future Strategy

What's New in v0.1.1

Added

• 🏃 Performance Benchmark Script: New ======================================================================
  pwalk.walk() vs os.walk() Performance Benchmark
  ======================================================================

Small Tree (depth=2, dirs=3, files=10):

Creating test tree in /tmp/tmp7xjzmrhm...
Test tree created: 40 files

Benchmarking os.walk()...
Benchmarking pwalk.walk()...

Results:
os.walk(): 0.0001s (590,054 files/sec)
pwalk.walk(): 0.0012s (34,509 files/sec)

Speedup: 0.06x
⚠️ os.walk() is 17.10x faster (small tree overhead)

Medium Tree (depth=3, dirs=5, files=20):

Creating test tree in /tmp/tmp7bdm_gu4...
Test tree created: 620 files

Benchmarking os.walk()...
Benchmarking pwalk.walk()...

Results:
os.walk(): 0.0009s (691,982 files/sec)
pwalk.walk(): 0.0010s (640,615 files/sec)

Speedup: 0.93x
⚠️ os.walk() is 1.08x faster (small tree overhead)

Large Tree (depth=4, dirs=4, files=30):

Creating test tree in /tmp/tmpirlslgdp...
Test tree created: 2,550 files

Benchmarking os.walk()...
Benchmarking pwalk.walk()...

Results:
os.walk(): 0.0023s (1,116,671 files/sec)
pwalk.walk(): 0.0022s (1,136,567 files/sec)

Speedup: 1.02x
✅ pwalk is 1.02x faster!

======================================================================
Benchmark Complete

Note: For large trees (millions of files), pwalk.walk() shows
significant speedup. Small trees may show overhead due to threading.

For real performance gains, run pwalk.report() on large directories:
python -m pwalk.report /large/directory to compare pwalk.walk() vs os.walk() performance
