Hi Peter,
Assuming I read you correctly, this means the directory containing
your fabfile is already in sys.path (i.e. you've added it to your
shell PYTHONPATH or similar), and comes after the location of your
Fabric source checkout, correct? In this situation, yes, I think it
would pick up Fabric's fabfile module before yours.
For what it's worth, I use Fabric with setup.py develop, and don't
have this problem -- most likely because my fabfile's containing
directory is *not* in my normal PYTHONPATH and thus, it's being added
explicitly to the very front of the path by line ~10 in
load_fabfile().
Let me know if I was right about your scenario (and if so, I'm curious
why it's set up that way, though I'm not implying by this that you're
doing anything wrong -- literally just curious!) and we can figure out
what the best approach is.
Offhand I think I could simply tweak the behavior such that if your
situation (containing dir is already in sys.path) comes up, that dir
gets moved temporarily to index 0, just like when it has to insert it,
and is then restored to its original index afterwards.
This ought to be sufficiently clean, while ensuring that the found
fabfile module is the imported one, no matter what.
Best,
Jeff

So in regards to this code:

# Get directory and fabfile name
directory, fabfile = os.path.split(path)
# If the directory isn't in the PYTHONPATH, add it so our
import will
work
added_to_path = False
if directory not in sys.path:
sys.path.insert(0, directory)
added_to_path = True
# Perform the import (trimming off the .py)
imported = __import__(os.path.splitext(fabfile)[0])
# Remove directory from path if we added it ourselves (just to
be neat)
if added_to_path:
del sys.path[0]
# Return dictionary of callables only (and don't include Fab
operations
or
# underscored callables)
return dict(filter(is_task, vars(imported).items()))
What it doesn't check is what is first on the path -- so all i have
been
getting is the fab commands (build_docs, push_docs, etc) whenever i
run fab
-l even though it is finding my fabfile.py. The reason is because my
src/fabric command is in my path before the "directory" mentioned
in the
code above is. So all that ever gets in the imported list is
commands from
fabric's fabfile.py.
Maybe this is because I run python setup.py develop? Not sure if
there is
any reason for me to have src/fabric in my path...
