rosnode.rosnode_ping fails when node restarted #221
Description
As you see below,
- when
rosnode_pingrun on python shell, node with old port number (? I'm not really sure what these number stand for) stays the same, which I assume triggers the error. - Commandline
$ rosnode pingseems to work fine.
Same thing happens when run in python code as you can imagine.
Reproduction and result:
1 Run a node. Say by $ rosrun turtlesim turtlesim_node
2 In a new terminal (term-commandline):
$ rosnode ping /turtlesim
rosnode: node is [/turtlesim]
pinging /turtlesim with a timeout of 3.0s
xmlrpc reply from http://130s-serval:42526/ time=0.695944ms
3 In another terminal (term-pythonshell):
$ python
>>> from rosnode import rosnode_ping
>>> rosnode_ping('/turtlesim', 1)
True
4 Stop a node.
5 On term-commandline:
$ rosnode ping /turtlesim
rosnode: node is [/turtlesim]
pinging /turtlesim with a timeout of 3.0s
ERROR: connection refused to [http://130s-serval:42526/]
6 On term-pythonshell:
>>> rosnode_ping('/turtlesim', 2)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<string>", line 370, in rosnode_ping
ERROR: connection refused to [http://130s-serval:42526/]
7 Run a node again.
8 On term-commandline:
$ rosnode ping /turtlesim
rosnode: node is [/turtlesim]
pinging /turtlesim with a timeout of 3.0s
xmlrpc reply from http://130s-serval:34981/ time=0.690937ms
9 On term-pythonshell:
>>> rosnode_ping('/turtlesim', 2)
