accessing data from the filesystem
by James Casbon 29 Sep '08

29 Sep '08

Hi, Is it possible to access data on the filesystem without uploading it. i.e. I install galaxy locally, and then want to refer to some huge fasta file on disk. At the moment, I can upload it, which is slow and creates two copies. Can I just point galaxy at it somehow? thanks, James

patch: use xml includes when parsing xml
by James Casbon 29 Sep '08

29 Sep '08

Hi, I have inlined a patch that allows xinclude statements in xml files. I presume I cannot send attachments to the list? Motivation: I have my own tools I am developing managed in tools/my_tools. I want to version that directory, etc, but want to be able to include new tools without editing the tools_conf.xml in galaxy_dist each time which would not get versioned. Solution: use xinclude to include an xml file that contains tool definitions. Example tool_conf.xml: <toolbox xmlns:xi="http://www.w3.org/2001/XInclude"> .... <xi:include href="tools/my_tools/tool_conf.xml" parse="xml" /> </toolbox> Patch below, cheers, James ============== diff -r 3b6771227a43 lib/galaxy/util/__init__.py --- a/lib/galaxy/util/__init__.py Fri Sep 26 09:10:04 2008 -0400 +++ b/lib/galaxy/util/__init__.py Mon Sep 29 15:50:20 2008 +0100 @@ -12,7 +12,7 @@ from galaxy.util.docutils_ext.htmlfrag import Writer as HTMLFragWriter pkg_resources.require( 'elementtree' ) -from elementtree import ElementTree +from elementtree import ElementTree, ElementInclude log = logging.getLogger(__name__) _lock = threading.RLock() @@ -64,6 +64,8 @@ def parse_xml(fname): """Returns an parsed xml tree""" tree = ElementTree.parse(fname) + root = tree.getroot() + ElementInclude.include(root) return tree def xml_to_string(elem): ================

Here is a LaunchDaemon for OS X, maybe useful.

Re: [galaxy-user] Install problems on OS X with python from macports

Hi Nate, Your fix works for the scramble fine, but not for the run.sh which now fails. On removing the -ES from run.sh, I get an error importing simplejson (see below). simplejson.egg is in the eggs/py2.5-noplatform dir so I dont' see why it doesn't pick this up if it manages to pick up WebHelpers.

We do start Galaxy with these flags: It's the egg downloader doing md5s on the files. I think there are two ways hashlib can work, and I think the macports way is to use the _hashlib c implementation, which goes missing from the path. This is probably because MacPorts choose to split out hashlib from the base install. > > -E Ignore environment variables like PYTHONPATH and PYTHONHOME that > modify the behavior of the interpreter. > > -S Disable the import of the module site and the site-dependent > manipulations of sys.path that it entails. > > This is so we can limit conflicts between our provided dependencies, and any > you may have installed locally. > > If you start the interactive interpreter, are you able to import _hashlib? > How about with -E and/or -S? Any output you can provide from where it > fails (I assume in scramble.py?) would be helpful. I can get hashlib from the interactive shell. Is there a way to get a shell with the galaxy environment? Here is the traceback. If you read hashlib, it tries to import _hashlib and if that fails and so it tries to get _md5. The MacPorts python should have _hashlib but not _md5 (as below). _hashlib cannot be found with the path for some reason.

OK I will try these flags out and see what happens. Thanks for the quick reply, James

Install problems on OS X with python from macports
by James Casbon 12 Sep '08

12 Sep '08

Hi Everyone, I'm trying to do a local install of Galaxy. My python version is from MacPorts. I realize that you recommend using MacPython, but since all the dev environment I have uses MacPorts, I thought I'd give it a go. BTW, it does work with the shipped python 2.5 with OS X. The problem I have is that the egg downloading part (scramble.py, etc.) seems to monkey with the pythonpath such that _hashlib cannot be imported. I tried to track what happens, but it is not obvious where and why the path is being changed. How can I safely add something to galaxy's pythonpath and ensure it is not removed? thanks, James

linking into galaxy
by Michael Rusch 05 Sep '08

05 Sep '08

I want to construct a link into galaxy that will show a particular dataset. The use case is that I have an external resource that references a galaxy dataset, and I want to provide a way to link to it. I will need to create these links fairly frequently to various datasets. I'm somewhat open as to how this could work. I'm running a local instance, so I have the ability to peek into the db to get any internal IDs that I might need for this purpose. I'm thinking a minimal implementation would be to get a history that includes the dataset and link to it based on that, though I'm not sure how I would build the URL. The next step up would be if there was some way for it to somehow highlight the particular dataset in the history. Or maybe scroll to it. Best thing would be a link that only required information about the dataset and not what histories it's a part of and could pick a history, or create a new history with only that dataset, something like that. Thanks, Michael
