Hi,
I'm hoping someone has come accross this error that can help me. I'm using
fabric to deploy a file to several remote servers. So I created a function in
my fabfile.py that takes care of this for me when I give it the local path to
get the file from. The issue is that each server gets a distinct file so I
have to go through host by host since I need to generate the file for each one
right before I call the put function. Bascially I have a main program that
calls this fab function through a subprocess, sort of like this:
main.py
...
servers # a list that contains the ip addresses for all my servers
for server in servers:
newlist=getListPath() # I know this works, I get the right path and it's valid
subprocess.call(['fab -H %s putfile:%s'%(server, newlist)], shell=True)
fabfile.py
....
def putfile(lpath):
rpath='some/path'
put(lpath,rpath)
This is the error that I get when I run the program:
Usage: fab [options] <command>[:arg1,arg2=val2,host=foo,hosts='h1;h2',...] ...

No such file or directory
So basically it prints out all the fab options and then at the end I get the
line right above. I know the file is real and it is at that location but I
don't know what the printout means. This happens for each of my servers, so I
know that it's going through each one at least.
The funny thing is that I created another script that does the same thing and
it works fine. The only real difference I can see is that for the one that
works I don't call the getListPath() right before but give it the same path. I
don't know if it matters much but in the getListPath() function I am calling
local, and all it returns is a string that happens to be the local path for
that list. I think I might be able to work around this by using ftp directly
but I would like to know why it keeps doing this.
Also as a sidenote is there a problem for functions taking in 2 arguments?
From the website I understand that you should be able to do this:
fab somefunction:arg1, arg2
But it reads the second argument as the ',' and tells me it's not valid?
I'm using the 1.3.4 version. Thanks in advance for your help,
