XRootDPyFS is a PyFilesystem interface to XRootD.

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

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")

Documentation is available at <http://xrootdpyfs.readthedocs.io/> or can be build using Sphinx:

pip install Sphinx
python setup.py build_sphinx

Running the tests are most easily done using docker:

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