[issue18458] libedit history offset workaround

[Ned Deily]

Ned Deily added the comment:

If you are using an existing binary installation, you could disable readline processing altogether by simply renaming the readline extension module, for example:

  cd /Library/Frameworks/Python.framework/Versions/3.3
  cd ./lib/python3.3/lib-dynload
  sudo mv readline.so readline.so.disabled

Of course, then you will not have interactive command line history and much of the editing features.  But it shouldn't crash.

If you don't mind using GNU readline (which is GPL licensed), you *might* be able to install the third-party readline module from PyPI:
   https://pypi.python.org/pypi/readline
But extension module building on unreleased systems may be problematic.  It may be easier to build on a currently supported system and move it.

As necessary, we will likely need to provide updates for the OS X installers in conjunction with the official release of 10.9.
