Bugfixes:

  • On Windows, carriage returns (CR) would be used on Python 2.7 when compareJIT files were created. The issue was fixed by replacing them with line breaks (LF)
  • .gitignore was backported from master
  • Fixate several python linter/test package versions on Travis/AppVeyor
  • Fix wrong-import-order pylint error messages
  • Python 3 was never properly supported on the 0.1 legacy branch, so stop running the linters using it
  • Move Travis on from the Trusty image to the Xenial one

This is the last point release on 0.1.x and marks the end-of-life of the 0.1 legacy branch.

Bugfixes:

  • Fix #185 - Commandline argument -t "js" in bot.py is not recognized. But it is mentioned in the readme.md.
  • Disable tests involving compile_shell on Python 2.7 mode unless Python 3.5+ is installed due to a mozilla-central requirement.
  • This temporarily lowers code coverage numbers reported to Codecov via Travis, until Python 3.5+ support is finished.
  • Integrated the isort Python checker into flake8 linting process
  • More automation / documentation / linting fixes

Notes:

  • Windows is still on the 0.1.x legacy branch, until Python 3.5+ support is completed

0.4.1

Compare

Bugfixes:

  • Fixed crashes in grabCrashLog by dealing with str/unicode types better
  • Made repos_update not update funfuzz anymore, since pip 10 no longer comes with a main method and we should not rely on the internals of pip
  • Simplified boto import code
  • Inlined platform detection code instead of relying on subprocesses
  • Tweaked Travis / AppVeyor CI configurations

Notes:

  • Windows is still on the 0.1.x legacy branch, until Python 3.5+ support is completed
