annotate mercurial/posix.py @ 13375:f1fa8f481c7c

port win32.py to using the Python ctypes library The pywin32 package is no longer needed. ctypes is now required for running Mercurial on Windows. ctypes is included in Python since version 2.5. For Python 2.4, ctypes is available as an extra installer package for Windows. Moved spawndetached() from windows.py to win32.py and fixed it, using ctypes as well. spawndetached was defunct with Python 2.6.6 because Python removed their undocumented subprocess.CreateProcess. This fixes 'hg serve -d' on Windows.
