I’m having an issue with using callables for env.roledefs. The documentation
suggests that they will only be called when executing a task that uses the role:
In addition to list/iterable object types, the values in env.roledefs (or value
of hosts key in dict style definition) may be callables, and will thus be
called when looked up when tasks are run instead of at module load time. (For
example, you could connect to remote servers to obtain role definitions, and
not worry about causing delays at fabfile load time when calling e.g. fab
--list.)
This does not appear to be the case from the following simple example also I
could not find a corresponding bug ticket, please let me know if one already
exists:
from fabric.api import *
def mycallable():
print "called"
return ["x.example.com"]
env.roledefs = {
"test": mycallable()
}
@task
def mytask():
print "Mytask called on %s" % env.roles
$ fab --list fabfile.py
called
Available commands:
Mytask
$ fab --version
Fabric 1.10.2
Paramiko 1.16.0
Thank you for your help,
