Please support GNU/kFreeBSD #202

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Hi,
in debian we have 2 flavors of GNU/kFreeBSD (amd64 and i386) and currently 
psutil is unable to detect those OSes since the check is too restrictive.

With the attached patch I'm able to build psutil and start the test suite, but 
I currently have 2 hangs:

- test_psutil.py - it hangs at "test_cmdline (__main__.TestCase) ..."
- test/test_memory_leaks.py - it hangs at "test_get_pid_list 
(__main__.TestModuleFunctionsLeaks) ..."

I'll see if I'll be able to debug it further in the coming days.

Regards,
Sandro

For today I've come up to the attached diff: it seems like several tests are 
hanging due to get_pid_list() . Currently it's implemented using a sysctl, but 
maybe the parameter passed are not the right ones for kFreeBSD. I've asked on 
the support IRC channel and they suggest to use a different approach: 
kvm_getprocs . the the kvm library interface is provided by most (of not all?) 
BSD descendants (f.e. FreeBSD, NetBSD, OpenBSD, DragonFlyBSD, Darwin, 
GNU/kFreeBSD too of course :) and Solaris too) - what do you think about it?

After skipping the hanging tests, there are still a lot of them failing (I'll 
try to nail them down in the coming days, if you don't beat me first ;)):

I'll try to reimplement get_pid_list() by using this kvm_getprocs() to fix 
get_pid_list() related failures and let you know once done.

As for test_get_num_threads and test_get_threads failures you might try to add 
a time.sleep(.1) call here:
http://code.google.com/p/psutil/source/browse/trunk/test/test_psutil.py#698
...and here:
http://code.google.com/p/psutil/source/browse/trunk/test/test_psutil.py#712

Open files/connections failures require lsof to be installed (hopefully I'll 
manage to re-implement that part in C and finally get rid of the stinky lsof 
python parser).

Other BSD-specific tests such as test_avail_virtmem and others just need to be 
adapted a bit or simply be skipped if there's a reliable way to detect we're on 
GNU/kFreeBSD (sys.platform?).

As for test_sys_cpu_times* I honestly have no clue. I have the code in front of 
me and I don't understand why it fails (it shouldn't).

Generally speaking, these failures are not that terrible and suggest that 
adding support for these arcane system I've never heard of might worth the 
effort. =)

This is interesting. Maybe it worths opening a report against bugs.python.org.

awesome! If you need some help or so I can handle you think ml:
debian-bsd@lists.debian.org (it's actually for Debian porting, but
they can help you on the bsd side of psutil).

even with the sleep I got:

maybe you can check the existance of lsof and skip the test if not there?

$ python -c "import sys; print sys.platform"
gnukfreebsd8

I'll give it a look on the machine, maybe I'll be lucky ;)

yeah, kfreebsd is very interesting since it's the only open source
solution with native zfs support (on linux is available under fuse,
which is kinda... slow...). Oh did I tell you we also have hurd (and
psutil will need work for that too, but we'll get to that later)?

It may just be a problem on with the chroot I was using or so - need
to investigate futher.

Yes, OpenBSD is currently not supported.

Mozilla imported psutil as part of the buildsystem & mach, so other real bsds 
(and debian/kfreebsd) ought to be supported. What should be the way to go, 
implement a backend for each of them, or try to stash everything in the 
existing bsd backend, with if/switches wrt the family ?

Some work was done a while ago for an older version (0.4.1) in 
https://github.com/jasperla/openbsd-wip/blob/master/sysutils/py-psutil/patches/p
atch-psutil__psbsd_py, i'll try to reapply that on top of master.

Glad to hear Mozilla adopted psutil! 

In order to add support for a new OS/architecture one should usually file an 
issue on the bug tracker so that we can keep track of the progress and provide 
a patch.

Alternatively I can give you commit privileges against the Mercurial repository 
and create a separate branch where you can develop and once everything is ready 
merge it back into trunk.

This issue is for GNU/kFreeBSD so if you're willkng to work on adding OpenBSD 
support please file a separate issue and we'll keep discussing there.

Thanks,

- Giampaolo

psutil has been migrated from Google Code to Github (see:
