Imagine it is early 2006, that there are only two users of sage, and you
don't know if there will ever be a third.   Then it is less wtf...

Yes, I'm so glad we can do this right and not have to maintain code
ourselves for this problem!   I spent way too much time on this stuff
in the early days of sage with ugly hacks (like running top and
parsing the output)...

I've used psutil in the past; it's a nice package.

Well, psutil goes way beyond what memory_info.py provides. The only 
logic that we would still need to keep from memory_info.py is these few 
lines, which can easily be inlined in the place where we need them:


limit = self.rlimit_address_space()
if limit < 0:
limit = self.total_swap() + self.total_ram()

# Use less than half of the addressable memory
return min(maxsize, limit)


Do you have an open ticket for testing psutil replacements?


Not yet.

[sage-devel] Add psutil as standard package

2016-09-07 Thread Jeroen Demeyer 

Hello,

at https://trac.sagemath.org/ticket/21421 we propose to add the Python 
package "psutil" as standard package for Sage. The tarball is 308KB, 
installed it is about 624KB. The use case is replacing 
src/sage/misc/memory_info.py


From https://pypi.python.org/pypi/psutil

psutil is a cross-platform library for retrieving information on running 
processes and system utilization (CPU, memory, disks, network) in Python.
