#4471: Arm crashes with 'ControlPort auto'
--------------------+-------------------------------------------------------
Reporter: atagar | Owner: atagar

Arm assumes querying 'GETCONF ControlPort' either provides an int or
fails. The new 'auto' argument breaks this assumption, causing a
stacktrace...
{{{
cba at cluster3:~$ sudo arm --interface 127.0.0.1:46632
Traceback (most recent call last):

return self._getRelayAttr("pid", None)
File "/usr/share/arm/util/torTools.py", line 1647, in _getRelayAttr
result = getPid(int(self.getOption("ControlPort", 9051)),
self.getOption("PidFile"))
ValueError: invalid literal for int() with base 10: 'auto'
}}}
On first glance there's four spots that need to be fixed...
{{{
atagar at morrigan:~/Desktop/arm$ grep -R "getOption(\"ControlPort" src/
src/cli/headerPanel.py: self.vals["tor/controlPort"] =
conn.getOption("ControlPort", "0")
src/cli/connections/connEntry.py: myCtlPort =
conn.getOption("ControlPort")
src/cli/graphing/connStats.py: self.controlPort =
conn.getOption("ControlPort", "0")
src/util/torTools.py: result =
getPid(int(self.getOption("ControlPort", 9051)),
self.getOption("PidFile"))
}}}
The change should be an isdigit check on the response and, if it fails,
use the default value (the second argument in the getOption call or None
if undefined).
This was caught by PurplePeter.
