Hi Shoham,
In this situation, I typically manually clear the cache :
from fabric.state import connections
def clear_fabric_cache():
if env.host_string in connections:
connections[env.host_string].close()
del connections[env.host_string]
Hope this helps,
Ronan
Hello everyone,
Thank you for building and maintaining such useful and well-done code
package.
I'm using fabric to connect to my virtual machines.
But every time I'm reverting a machine, fabric fails because it caches
it's connections (see traceback at the bottom)
If I'm to explain by the code, in fabric/network.py, line 158, fabric
checks if a connection to the requested address was already made, use that
same session.
But if my VM was reverted, the session is not synced and I need fabric to
re-connect.
So is there a way to force fabric to ignore or empty the cache, or maybe
to try again if the connection was unsuccessful?
Thank you all again,
Shoham
