Provide function to get system disk partitions #174

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
In issue 172 we added psutil.disk_usage() function which provides disk usage 
statistics starting from a given path.
What's missing is a facility to get all system partitions (mount points) to be 
used in conjunction with psutil.disk_usage() which would provide all the pieces 
to perform a complete monitoring of all disks instealled on the system.

What I have in mind:

>>> psutil.disk_partitions()
[partition(device='/dev/sda3', mountpoint='/', fstype='ext4')
partition(device='/dev/sda7', mountpoint='/home', fstype='ext4')
partition(device='/dev/sdb1', mountpoint='/media/1CA0-065B', fstype='vfat')
partition(device='/dev/sda6', mountpoint='/media/Dati', fstype='fuseblk')]

The way I see it, disk_partitions() should return information about *mounted* 
physical devices only, and hence behave more like "df" rather than "fdisk -l".
Also, "df" reports mount points which doesn't refer to actual physical devices, 
such as "/dev/shm" ( 
http://www.cyberciti.biz/tips/what-is-devshm-and-its-practical-usage.html ), 
"/var/run" and "/var/lock". 
IMO, we should ignore them.

Attached is a draft for Linux.
Still have to look into other implementations.

Implemented on Linux in r1026.
I provided an "all" optional argument defaulting to False to filter for 
physical devices only.

>>> psutil.disk_partitions()
partition(device='/dev/sda3', mountpoint='/', fstype='ext4')
partition(device='/dev/sda7', mountpoint='/home', fstype='ext4')
partition(device='/dev/sdb1', mountpoint='/media/1CA0-065B', fstype='vfat')
partition(device='/dev/sda6', mountpoint='/media/Dati', fstype='fuseblk')
>>>

>>> psutil.disk_partitions(all=True)
partition(device='/dev/sda3', mountpoint='/', fstype='ext4')
partition(device='proc', mountpoint='/proc', fstype='proc')
partition(device='', mountpoint='/sys', fstype='sysfs')
partition(device='fusectl', mountpoint='/sys/fs/fuse/connections', 
fstype='fusectl')
partition(device='', mountpoint='/sys/kernel/debug', fstype='debugfs')
partition(device='', mountpoint='/sys/kernel/security', fstype='securityfs')
partition(device='', mountpoint='/dev', fstype='devtmpfs')
partition(device='', mountpoint='/dev/pts', fstype='devpts')
partition(device='', mountpoint='/dev/shm', fstype='tmpfs')
partition(device='', mountpoint='/var/run', fstype='tmpfs')
partition(device='', mountpoint='/var/lock', fstype='tmpfs')
partition(device='/dev/sda7', mountpoint='/home', fstype='ext4')
partition(device='binfmt_misc', mountpoint='/proc/sys/fs/binfmt_misc', 
fstype='binfmt_misc')
partition(device='gvfs-fuse-daemon', mountpoint='/home/giampaolo/.gvfs', 
fstype='fuse.gvfs-fuse-daemon')
partition(device='/dev/sdb1', mountpoint='/media/1CA0-065B', fstype='vfat')
partition(device='/dev/sda6', mountpoint='/media/Dati', fstype='fuseblk')

Attached is a patch for OS X support.  It is identical to BSD support but I 
couldn't find a good way to share code between the BSD and OS X 
implementations.  That being said, I copied the approach for BSD to implement 
OS X support.  If you know a better way to do this so that OS X uses the BSD 
sources for this, since OS X is a BSD derivative, feel free to just commit your 
version.

Added in r1047.
As for now I can't think of a smart way to share the same code between OSX and 
FreeBSD. I'll think about it later. Closing out as FixedInSvn for now.
