xrootdpyfs 0.1.5

XRootDPyFS is a PyFilesystem interface to XRootD.

XRootDPyFS is a PyFilesystem interface to XRootD.

Getting started

If you just want to try out the library, the easiest is to use Docker.

$ docker build -t xrootd .
$ docker run -h xrootdpyfs -it xrootd bash

Next, start a XRootD server in the container and fire up an ipython shell:

[xrootdpyfs@xrootdpyfs code]$ xrootd -b -l /dev/null
[xrootdpyfs@xrootdpyfs code]$ ipython

Quick examples

Here is a quick example of a file listing with the xrootd PyFilesystem integration:

>>> from xrootdpyfs import XRootDPyFS
>>> fs = XRootDPyFS("root://localhost//tmp/")
>>> fs.listdir("xrootdpyfs")
['test.txt']

Or, alternatively using the PyFilesystem opener (note the first import xrootdpyfs is required to ensure the XRootDPyFS opener is registered):

>>> import xrootdpyfs
>>> from fs.opener import opener
>>> fs, path = opener.parse("root://localhost//tmp/")
>>> fs.listdir("xrootdpyfs")
[u'test.txt']

Reading files:

>>> f = fs.open("xrootdpyfs/test.txt")
>>> f.read()
'Welcome to xrootdpyfs!'
>>> f.close()

Reading files using the getcontents() method:

>>> fs.getcontents("xrootdpyfs/test.txt")
'Welcome to xrootdpyfs!'

Writing files:

>>> f = fs.open("xrootdpyfs/hello.txt", "w+")
>>> f.write("World")
>>> f.close()

Writing files using the setcontents() method:

>>> fs.setcontents("xrootdpyfs/test.txt", "World")

Testing

Running the tests are most easily done using docker:
