[Question] gfal-copy failed with Segmentation fault

[a6350202]

Hello again, due to this question is not related to my pervious one, I create a new issue.

I need to use gfal2 to run Rucio command (download/upload), but after running to this line leads to Segmentation fault: 11.

> /opt/rucio/lib/rucio/rse/protocols/gfal.py(369)__gfal2_copy()
-> ret = ctx.filecopy(params, str(src), str(dest))
(Pdb)
Segmentation fault: 11

So I try to initial a virtualenv (follow README of this project), and run gfal-copy command also get error: Segmentation fault: 11.

Segmentation fault: 11

My MacBook OS version: 10.12.6 Python version: 2.7.10

Hi, from the logs looks like you cannot access the local certificate. do you have one and with the correct permission? thanks Andrea

[a6350202]

Yes, I have one. But there is no permission on my certificate to access storage. I try to copy our root proxy as /tmp/x509up_u0 and execute gfal-copy again.

The error of secgsi_InitProxy: cannot access private key file: /var/root/.globus/userkey.pem didn't occur. and it still show Segmentation fault: 11:

(.venv) Mandyde-MacBook-Pro:dicos-rucio root# gfal-copy README.rst xroot://<our_storage>//eos/tmp/README.rst
Segmentation fault: 11

[andrea-manzi]

are you running as root? cause otherwise the proxy should be the one of the user ( /tmp/x509up_u

you should also use the file:/// protocol if you want to copy from local file:

gfal-copy file:///README.rst xroot:////eos/tmp/README.rst

[a6350202]

Sorry for the late reply... Yes, I am running as root and the proxy file name is also right...

I try your command gfal-copy file:///opt/dicos-rucio/README.rst xroot://<our_storage>//eos/tmp/README.rst

still shows Segmentation fault: 11

sorry i was not able to test it so far as my Mac was being repaired. i have the same problem on gfal-copy, ( other commands are working though) i'm going to investigate

This should be fixed now: https://its.cern.ch/jira/browse/DMC-1026

[andrea-manzi]

i can confirm that the segmentation fault is gone, thanks @chrisburr for the fix
