• Fixed: inode should be unsigned.
• Fixed unicode handling on PyPy due to Py_FileSystemDefaultEncoding always being NULL there.
• Improve tests on PyPy and Windows.
• Add Travis and Appveyor CI testing.

Tested with python-pickleshare, the only current reverse dependency.

from pickleshare import *
db = PickleShareDB('~/testpickleshare')
db.clear()
print("Should be empty:", db.items())
db['hello'] = 15
db['aku ankka'] = [1,2,313]
db['paths/are/ok/key'] = [1,(5,46)]
print(db.keys())
