Hello again,
The error message: could not make temporary directory: `/var/lib/condor/execute/dir_33779/Graph_Xmgrace_23' etc
only appears on HTcondor when the perl script contains more than one call to xmgrace.Adding permission changes before the perl script is called:
chmod g+w $TEMP
chmod g+w $TMPDIR
chmod a+rw ${PWD}Assuming that ${PWD} is in fact the temporary /var/lib/condor/execute/dir_*
has no effect on the error even though it does change the permissions:
drwxrw-rw-. 2 390870428 390800513 Â202 Oct 29 22:48 .
But still the error persists.
It is rather strange... and the error does not occur on a the Mac when usingdocker run
â
Any idea?JYS

Subject: Re: [HTCondor-users] Fw: Xvfb | Docker Universe | Can't open display | (but works with docker run)ÂHello Dima,
Thank you veryÂmuch for takingÂthe time to answer so promptly.I am just an "end user" tryingÂto make things work. (i tried many things before replying...)
I found the Display problem:Â the following line is necessary to have Xvfb active (on DISPLAY named :99) and can be added to the script or source from /etc/bashrc
Xvfb :99 -ac &
However, I encounter another problem reported in the error output:
could not make temporary directory: `/var/lib/condor/execute/dir_33779/Graph_Xmgrace_23' at /usr/local/share/perl5/Chart/Graph/Xmgrace.pm line 136.
The directory name varies. This time it ends with23
â but another time it ended with21
â so it's not predictable.
Lines 135 and 136 from the Xmgrace.pm file say: Â135  Â# create tmpdir Â136  Â_make_tmpdir("_Xmgrace_"); # grace files should be saved for user tweakingÂ
Is there a way to fix this permission issue?
I don't have these issues when running on the Mac: I "pushed" the image onto the hub, and it is available to test. I included the simpletest.pl
â file into the/home
â directory on the image. In that case there is no need for-v
â to test:
This is what I can do on my Mac from a Terminal:
docker run -it --rm -w /home Âjysgro/xmgrace-c7
This creates a new container, with interactive Terminal, which will be removed when usingexit
â and goes directlyÂinto the/home
â directory. There is a single file calledtest.pl
â which can then be executed within the container with:perl test.pl
â
When this is done, the/home
â directory will contain 3 files:test.pl Âxmgrace1.agr Âxmgrace1.png
and that means that the program worked fine.
If there is a temporary directory to create it is not a problem there but it is on HTCondor.
Is there a permission to be given so that temporary directories can be created ?
THank you!
Jean-Yves

How does it "work fine" outside of condor?
Access to host XVfb is via a socket in /tmp/.X11-unix, are you mounting
it with `-v` for the non-condor runs? Or are you firing up Xvfb inside
the container?
For the former, my guess is you should be able to mount the socket as
per
