Regarding Python libraries, we could use upstream xrootd or even our xrootdpyfs.
Both options look good to me. 👍
How to choose b/w these two 😅 ?

This will need to amend also Dockerfile
to have xrootd
support there. There are two options:
a) Currently we are based on python:3.8-slim
which is basically a stripped-down Debian distribution. Either we compile xrootd
there in the usual way, or look forxrootd
packages, e.g. for Ubuntu 18.04 LTS one can use:
$ echo 'deb http://storage-ci.web.cern.ch/storage-ci/debian/xrootd/ bionic master' >> /etc/apt/sources.list
$ curl -sL http://storage-ci.web.cern.ch/storage-ci/storageci.key | apt-key add -
$ apt-get update
$ apt-get install xrootd-client
b) We can switch our base image to CentOS7, which is what CERN batch farms typically use, where xrootd
can be installed via EPEL:
$ yum install epel-release
$ yum update
$ yum install xrootd-client
Note that we have some prior art in opendata.cern.ch
repository (see its Dockerfile
) or in reana-env-root6
(this is for ROOT, but analogously one can do xrootd
).
@ParthS007 please let me know if you shall look into adding xrootd
to our Docker image yourself or whether I should.
In addition to http protocol implemented in #22, we should add support for xrootd protocol which provides more bandwidth.
Check whether client system contains xrootd commands (
xrdcp
) or Python libraries (xrootd
).If yes, enable support for
--protocol root
.If not, report help string what people has to do do install them.
This is not an MVP functionality for the first public release; it can be added later.
