[ovirt-devel] Ensure processes death by terminating decorator - https://gerrit.ovirt.org/51407

[Yaniv Bronheim]

Hi guys,

Following the work to omit deathSignal attribute from our cpopen
implementation we posted https://gerrit.ovirt.org/51407 which is ready for
use.
Currently locations that should use it are:
(I wrote above who I expect to check the area and post a patch for that -
we'll discuss it during next vdsm-sync to follow the work)

shavivi:
vdsm/v2v.py - in _start_virt_v2v you return aysnProc that should call
kill() on fail

fromani:
vdsm_hooks/checkimages/before_vm_start.py - in checkImage - the code looks
ok, but check if not better to use the terminating decorator.. I think it
will be nicer

nsoffer:
vdsm/storage/mount.py - good looks ok, I prefer to use terminator there
vdsm/storage/iscsiadm.py
vdsm/storage/imageSharing.py
vdsm/storage/hba.py -good handling, use terminator
vdsm/storage/blockSD.py

please check your usage with the returned process and see that you're not
depending on deathSignal for it to die properly on crush

some places define deathSignal for no reason, the call is sync - please
remove those places:

nsoffer:
lib/vdsm/qemuimg.py
vdsm/storage/curlImgWrap.py
vdsm/storage/storage_mailbox.py
vdsm/storage/misc.py

fromani:
lib/vdsm/virtsparsify.py

ybronhei:
vdsm/API.py


If you can't get to it in a reasonable time, add the task to the list [1]
and someone else will be it up.
Please try to go over before the sync call.
