Hello, Yes, this is sometimes problematic. You may have seen this, but a discussion about this same topic took place on the galaxy-dev@bx.psu.edu mailing list earlier. It has more details about why this can occur. Also, please try the work-around Jeremy suggests and see if that helps. http://lists.bx.psu.edu/pipermail/galaxy-dev/2013-December/017773.html Take care, Jen Galaxy team On 12/18/13 4:48 AM, Alessandro Ogier wrote:

Dear galaxy users,

here at European Institute of Oncology we're deploying a brand new galaxy install, but facing problems with history (re)importing.

We have configured a galaxy running on one node where users took a "sneek peek" on features while developing a real deployment on nfs and cluster integration. Now I have to migrate histories to new galaxy install, I'm doing that on behalf my users because we choose to integrate with an apache proxy that does reverse proxying and ldap authentication.

Yesterday I produced four tar.gz for a user, placed on a temporary webserver and then proceeded with reimport on new instance: two where reimported, two not.

All those files are relatively small (from 1MB to 13MB), and no clues from galaxy debug log:

sorry for line wraps, I also attached logs.

I cloned your repository on my development machine to try to recreate/debug this issue but unfortunately this time I'm unable to import successfully any history (plain galaxy instance, sqlite, no ext user, no job_conf, either default and stable branches).

I'm attaching the new galaxy instance universe_wsgi.ini and job_conf.xml, as you can see they are pretty straight-forward.

What I'm asking to you : which is the correct way for debugging this sort of things ? No luck putting some debugging code in

* lib/galaxy/tools/actions/history_imp_exp.py * lib/galaxy/tools/imp_exp/unpack_tar_gz_archive.py

maybe I'm missing something ...

also, I'd like to contribute some patch on a couple of minor glitches I found, but I'll write to -dev list for that

Thank you, and thanks for this great tool :) ciao
