  1. Hi folks,
    I'm pleased to announce the 0.5.0 release of psutil:
    http://code.google.com/p/psutil/

    === Major new features ===

    - system users
    - (Linux, Windows) process CPU affinity (get and set)
    - (POSIX) process number of opened file descriptors.
    - (Windows) process number of opened handles.
    - psutil.disk_partitions() now provides also mount options
    - new Process.as_dict() method.
    - Process.get_children(recursive=True): return all process descendants.
    - 2to3 is not longer required to run at installation time in order to
    support Python 3
    - ppid, name, exe, cmdline and create_time properties of Process class
    are now cached after being accessed.
    - psutil.process_iter() now caches Process instances between calls.

    For a complete list of features and bug fixes see:
    http://psutil.googlecode.com/svn/trunk/HISTORY


    === New features by example ===

    >>> import psutil, os

    [user(name='giampaolo', terminal='pts/2', host='localhost',
    started=1340737536.0),
    user(name='giampaolo', terminal='pts/3', host='localhost',
    started=1340737792.0)]
    >>>
    >>> psutil.disk_partitions()

    [partition(device='/dev/sda1', mountpoint='/', fstype='ext4', opts='rw,nosuid'),
    partition(device='/dev/sda2', mountpoint='/home', fstype='ext, opts='rw')]
    >>>
    >>> p = psutil.Process(os.getpid())
    >>> p.get_num_fds()

    4
    >>>
    >>> p.get_num_handles() # windows only

    254
    >>>
    >>> p.get_memory_maps()

    [mmap(path='/lib/x86_64-linux-gnu/libutil-2.15.so', rss=16384,
    anonymous=8192, swap=0),
    mmap(path='/lib/x86_64-linux-gnu/libc-2.15.so', rss=6384,
    anonymous=15, swap=0),

    >>>
    >>> p.as_dict()

    {'status': 0, 'pid': 29510, 'connections': [], 'cmdline': ['python'], ...}
    >>>
    >>> p.get_cpu_affinity()

    [0, 1, 2, 3]
    >>> p.set_cpu_affinity([0])
    >>>
    >>> p.get_children(recursive=True)

    [<Process...>, <Process...>, ...]
