[gentoo-commits] gentoo-x86 commit in eclass: python.eclass

[Arfrever Frehtes Taifersar Arahesis (arfrever)]

arfrever    10/02/28 11:48:41

  Modified:             python.eclass
  Log:
  Define phase functions always in packages supporting installation for multiple versions of Python. Export phase functions when PYTHON_DEFINE_DEFAULT_FUNCTIONS is defined.
  Extract sanity checks from validate_PYTHON_ABIS() to _python_initial_sanity_checks() and _python_final_sanity_checks().
  Support --final-ABI option of python_execute_function().
  Extract setting of color variables to _python_set_color_variables().
  Simplify python_copy_sources() by not supporting --no-link option and always creating real copies of files.
  Call _python_initial_sanity_checks() and _python_final_sanity_checks() in python_set_active_version().
  Simplify PYTHON() by not supporting --active option.
  Deprecate python_tkinter_exists().
