ROS_IP set by default upon sourcing in Windows #430

It looks like this file
That file on linux is pretty much blank. Seems like you would have to set the ROS_HOSTNAME environment variable before activating the conda environment, and it would work how I expect. |
So this is a weird hack to avoid strange performance issues, the PR that added the change is here Following the chain all the way to |
Hi @gftabor, thanks for reporting this! Are you happy to open a PR that removes the undesired behaviour in ros_comm? Happy to review + merge. |
I made a PR directly to ros_comm, seems like the weird behavior is all upstream. If they don't accept the PR there then we can look at making patch here in robostack |
xref: ros/ros_comm#2364 |
Solution to issue cannot be found in the documentation.
Issue
Robostack on windows automatically sets ROS_IP to local host (incorrect behavior) but not doing it on linux (correct behavior).
The problem is I was setting ROS_HOSTNAME but ros was choosing to listen to IP over HOSTNAME when both were set. On linux neither ROS_IP nor ROS_HOSTNAME environment variables are set by default, so its easier to overwrite

Interestingly
C:\Users\tabor\anaconda3\envs\foundations\etc\conda\activate.d\ros-noetic-catkin_activate.bat
doesn't mention ROS_MASTER_URI or ROS_IP but both are set.Installed packages
