2Fdevshed.bx.psu.edu%2F&includes_tool_dependencies=True HTTP/1.1 Here is the POSTed data: install_repository_dependencies=true&install_repository_dependencies=tru e&install_tool_dependencies=true&install_tool_dependencies=true&shed_too l_conf=.% 2Fshed_tool_conf.xml&new_tool_panel_section=Test&select_tool_panel_secti on_button=Install The POSTed URI is 8,320 bytes. The encoded_repo_info_dicts account for 8,113 (97.5%) of these bytes. In this particular case, it appears that the relevant code can be found in install_repositories_by_revision() in lib/galaxy/webapps/ tool_shed/controllers/repository.py and in prepare_for_install() in lib/galaxy/webapps/galaxy/controllers/admin_toolshed.py. It's possible that there's code elsewhere that also passes the encoded_repo_info_dicts in the request, which would trigger the same issue. -rico On Sep 26, 2013, at 9:21 AM, Greg Von Kuster wrote:

Hi Rico,

Can you provide the specific GET request URL with which you encountered this problem? There are very few GET requests when installing repositories from the tool shed - the only one I can locate without a lot of digging is the following, which I don't think is causing the problem.

# Get the information necessary to install each repository. url = suc.url_join( tool_shed_url, 'repository/get_repository_information? repository_ids=%s&changeset_revisions=%s' % \ ( repository_ids, changeset_revisions ) )

Thanks,

Greg Von Kuster

Folks,

After checking a little closer last night, I have one clarification. The Tool Shed does use POSTs as well as GETs, but even when it's POSTing, the encoded dictionaries (encoded_repo_info_dicts) are part of the query string. The encoded_repo_info_dicts should probably become part of the POSTed data.

When installing Galaxy Tool Shed repositories into a local Galaxy instance, tool shed dependecies are exchanged as an encoded python dictionary via the HTTP GET method.

If a tool shed repository contains enough dependencies, the length of this encoded dictionary can become extremely long. In my case, it became long enough for my Apache server to choke on it:

[Wed Sep 11 15:34:53 2013] [error] [client XXX.XXX.XXX.XXX] request failed: URI too long (longer than 8190)

The HTTP standard does not place a limit on the length of a URI, but the de facto limit is 2000 characters. See the following stackoverflow answer:

http://stackoverflow.com/a/417184

I would recommend either: 1) communicating toolshed dependencies via an HTTP POST 2) redesigning tool shed <-> instance communications

As a stopgap measure, I've modified lib/tool_shed/util/ encoding_util.py to use a more compact encoding scheme. I'm attaching a copy in case someone else runs into the same problem.
