python::v5.0.1 cannot copy files

[adriansev]

Hi! when trying to copy a file with v5 i get this:

jobID: 1/1 >>> Start
Plugin No such file or directory loading sec.protocol libXrdSecsss-5.so
Failed download: /alice/cern.ch/user/a/alitrain/PWGGA/GA_pp_AOD/1536_20200914-1445_child_10/merge_runlist_7/root_archive.zip
Succesful copy jobs: 0/1

the logs are here: https://cernbox.cern.ch/index.php/s/bF4JZnoc9bVl3lT
@simonmichal Any idea about this?
If you need i can throw some test files around to see if there is a problem with the EOS

[adriansev]

so, it seems that there was the problem with the server .. but i still get
Plugin No such file or directory loading sec.protocol libXrdSecsss-5.so
when i copy from EOS, the plain xrootd does not give such error

Hi Adrian, thanks for reporting this problem, I will have a look!

@adriansev : just to keep you updated, I was able to reproduce this problem, now let's fix it ;-)

[simonmichal]

@adriansev : from what I see this affects only pip distribution, the rpath in xrootd plugins is not set correctly and they cannot load dependencies, this should fix the problem: 47103aa

@simonmichal i tested the latest master (local built)

python3 -c "from XRootD import client; print(client.__version__)"
20200923-47103aa44

and tried a couple of EOS instances and things looks ok, no more warning message. for me this looks ok, is it ok to close?
also, please do not forget to backport these patches to stable branches :)
Thanks a lot!!

@adriansev : thanks for testing! yes, please close!

P.S. it's already backported to the stable 4.12.x branch
