[Bug 599185] Re: Another instance of Camera Monitor is already running
Well this issue will be irrelevant in the new version of cameramonitor - 0.3.1 that i am proposing... Because it uses dbus for detection of other running instances... (see my PPA - https://edge.launchpad.net/~phobosk/+archive/phobosk-ppa ) The problem is that I cannot contact the original author of the program so we can arrange a release of the new version officially...

[Bug 599185] Re: Another instance of Camera Monitor is already running
I agree. That does seem to be a better solution. It is a bit disconcerting that the /proc/#/comm file isn't documented in the manfile for proc, at least with 10.10, but it does work. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/599185 Title: Another instance of Camera Monitor is already running -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 599185] Re: Another instance of Camera Monitor is already running
Thank you for your insight and your suggested fix, edemeulle. I have run
into this bug myself and it can be rather annoying.
I have some experience with python, although I know little about /proc
and what kinds of things the cmdline entry for a process might
possibly contain in general. I was just thinking that it would be
possible that (in the future) camera monitor might commonly be started
with some arguments and thus it may break your suggested fix (as the
arguments will be included in /proc/pid/cmdline and thus the string
would no longer end with cameramonitor).
If my mild concern is justified, then (afaik) it would be better to
check the comm entry in proc, rather than cmdline.
Also, I would guess that fd should by closed, after use, so perhaps an
overall slightly better version of this fix would be:
# Check if the process with pid is running
def pid_running(pid):
if os.path.isdir('/proc/'+pid):
with open('/proc/'+pid+'/cmdline') as fd:
cmd = fd.read()
return cmd.strip() == 'cameramonitor'
else:
return False
I hope this helps!

[Bug 599185] Re: Another instance of Camera Monitor is already running
Well, that was silly of me... forgot to fix my fix for the fix :S .
Here's what I meant to post:
# Check if the process with pid is running
def pid_running(pid):
if os.path.isdir('/proc/' + str(pid)):
with open('/proc/' + str(pid) + '/comm') as fd:
cmd = fd.read()
return cmd.strip() == 'cameramonitor'
else:
return False
I also added conversion of pid to a string, in case it is ever passed
as an integer. Testing this on the interactive prompt worked fine for
me.

[Bug 599185] Re: Another instance of Camera Monitor is already running
The problem is the camermonitor doesn't always delete the
~/.cameramonitor.pid file and *sometimes* that PID is in use by another
program.
Replacing the following function in
/usr/shared/pyshared/cameramonitor/utils.py will fix the problem by
checking if the PID that ~/.cameramonitor.pid refers to actually is
running cameramonitor:
# Check if the process with pid is running
def pid_running(pid):
if os.path.isdir('/proc/'+pid):
fd = open('/proc/'+pid+'/cmdline')
cmd = fd.read()
return cmd.strip('\x00').endswith('cameramonitor')
else:
return False

Hi! Deleting this pid file solved the problem. You dont have to delete it every startup. One time and the problem is solved. Great! Thanks!

[Bug 599185] Re: Another instance of Camera Monitor is already running
I had this problem as well. The program uses a file ~/.cameramonitor.pid to save the current PID. If it crashes and the PID isn't active all is well. However, if for some reason the old PID matches something that is already running it gives the error. The easy solution is to just delete .cameramonitor.pid. Moving forward the program should check the /proc/PID/cmdline to make sure it truly is already running. -- Another instance of Camera Monitor is already running https://bugs.launchpad.net/bugs/599185 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
