v6.0.0 [OLD]

[chrissimpkins]

Changes (so far... This is currently WIP)

• update pngquant to v2.13.0 (Update pngquant to v2.13.0 #80)
• update zopfipng derivative to v2.3.0 (Update zopflipng derivative to v2.3.0 #81)
• add GH Actions configurations for cPy2.7, 3.6-3.9, pypy3 testing on macOS + Linux (Add GH Actions configurations for cPy3.6-3.9, pypy3 testing on macOS + Linux, Py+shell linting, add macOS benchmarks, remove Travis CI unit tests #84)
• add macOS platform benchmarking on GH Actions runners (Add GH Actions configurations for cPy3.6-3.9, pypy3 testing on macOS + Linux, Py+shell linting, add macOS benchmarks, remove Travis CI unit tests #84)
• add Linux platform benchmarking on GH Actions runners (Add GH Actions configurations for cPy3.6-3.9, pypy3 testing on macOS + Linux, Py+shell linting, add macOS benchmarks, remove Travis CI unit tests #84)
• add CodeQL security analysis testing (Add CodeQL static source analysis #83)
• use black -l 90 source code style in Python source
• add setup.cfg with flake8 line length configuration (c8aa038)

Tentative

• include new --force option to overwrite optimized files in place (Add option to replace the original file with -f flag #76), dev branch implementation needs to be refactored with functools.partial approach. This will eliminate the need for a global variable.
• catch CTRL-C / SIGINT and close all child processes (Terminate crunch executable with Ctrl+C #79), SO
• open to any new backward incompatible changes. Let me know if anything comes to mind.

Notes

• It appears that we may achieve a modest performance improvement (time) with the new pngquant/zopflipng version combination. I may push the zopfli optimization a bit more to see how much file size improvement we can achieve without a significant impact on processing times.
• Py3.8 on Travis Ubuntu Linux env is broken for some reason. Currently troubleshooting Moved to GH Actions and am now testing across cPy2.7, 3.6 - 3.9, pypy3 on macOS and Linux platforms. All unit tests are passing.

TODO

• zopflipng bug fix pushed in Update lodepng to 20201017 google/zopfli#176, rebase on these changes
