Hello all,

While trying to install the Glimmer3 wrapper from the Tool Shed I noticed some very wrong looking paths, including this warning at the terminal where run.sh was open,

Warning: local() encountered an error (return code 1) while executing 'echo 'PYTHONPATH=$PYTHONPATH:/opt/galaxy-dist/"../galaxy-dist-shed-tools"/biopython/1.61/biopython/package_biopython_1_61/5d0c54f7fea2/lib/python; export PYTHONPATH' > '/opt/galaxy-dist/"../galaxy-dist-shed-tools"/biopython/1.61/bgruening/glimmer3/ab12adaa5cc2/env.sh';chmod +x '/opt/galaxy-dist/"../galaxy-dist-shed-tools"/biopython/1.61/bgruening/glimmer3/ab12adaa5cc2/env.sh''

From my configuration file,

$ grep tool_dependency_dir universe_wsgi.ini tool_dependency_dir = "../galaxy-dist-shed-tools"

Installation of the dependencies failed. I removed the quotes in the tool_dependency_dir setting, restarted Galaxy, uninstalled Glimmer3 and the Biopython dependency, and then re-installed Glimmer3.

This time the paths in the terminal looked sensible, although there was still a warning:

Warning: local() encountered an error (return code 255) while executing 'export PYTHONPATH=$PYTHONPATH:/opt/galaxy-dist-shed-tools/biopython/1.61/biopython/package_biopython_1_61/5d0c54f7fea2/lib/python &&

I think that is related to the currently broken dependency issue I mentioned here: http://lists.bx.psu.edu/pipermail/galaxy-dev/2013-August/015971.html

I would expect Galaxy to strip the quotes (after all, they are commonly used to escape filenames with spaces). Perhaps it is but doing so inconsistently? It appears Python's path checking is a bit odd here:

$ python Python 2.7.2 (default, Aug 6 2013, 16:54:30) [GCC 4.1.2 20080704 (Red Hat 4.1.2-50)] on linux2 Type "help", "copyright", "credits" or "license" for more information.

os.path.isfile(q)

os.path.join(os.path.curdir, p)

os.path.join(os.path.curdir, q)

'./"../galaxy-dist-shed-tools"'

os.path.isdir(os.path.join(os.path.curdir, p))

True

os.path.isdir(os.path.join(os.path.curdir, q))

True

...

...

os.path.abspath(p)

'/opt/galaxy-dist-shed-tools'

...

...

os.path.abspath(q)

'/opt/galaxy-dist/"../galaxy-dist-shed-tools"'

...

...

os.path.isdir(os.path.abspath(p))

True

...

...

os.path.isdir(os.path.abspath(q))

True

...

...

quit()

This feels like a bug in the Python os module to me?

Anyway, a quick hack to fix this would be to strip the quotes when loading file or path names from the configuration file - or abort with a clear error telling the user to remove them?
