I recently updated my htpc running Freevo 1.9.0 on Gentoo.
As part on the update process, Python 2.6 was installed.
After some time I realized that I'm no more able to shutdown freevo and
any of the helpers I'm running (recordserver and webserver) because
freevo pretend that they are not running:
i...@htpc ~ $ freevo webserver --stop --debug
[SNIP]
stop(name='webserver', arg=['python',
'/opt/freevo/lib/python2.6/site-packages/freevo/helpers/webserver.py'])
getpid(name='webserver', args=['python',
'/opt/freevo/lib/python2.6/site-packages/freevo/helpers/webserver.py'])
4:fname='/tmp/webserver-1000.pid' pid=0 arg='python'
cannot kill 'webserver' no pid
webserver not running
Well... trust me: the webserver _is_ running ;)
Looking at the debug messages (and then at the freevo code), it seems
that the getpid() function expect the name of the python executable to
be "python", while on my Gentoo system the name is instead
"/usr/bin/python2.6".
Gentoo allows you to have more than one version of python present on the
same system. You can select which one you want to use by running
"eselect python set <version>". /usr/bin/python is actually a simlink to
/usr/bin/python-wrapper, so I straced it and discovered that it
basically reads a configuration file (which is a text file containing
just the string "python2.6") and than execve("/usr/bin/python2.6"). This
is the reason of the difference in the executable names. Judging by the
dates, it seems that the python-wrapper executable has been installed
during the last update.
Unfortunately, I do not have the necessary programming skills to fix it
myself and can't do much more than reporting the problem.
By now, I'll continue to send TERM signals around ;)
Cheers,
izio
