Darnit, I should have tried downloading again before sending the email - that solved the issue. Newest version of upload.py doesn't make use of from_json_string Cheers, Rob ________________________________ From: Robert Davidson <bobbledavidson@yahoo.co.uk> To: "galaxy-dev@lists.bx.psu.edu" <galaxy-dev@lists.bx.psu.edu> Sent: Monday, 3 November 2014, 15:33 Subject: Problems with upload.py and changes to json.py Dear Galaxy-Dev, Last week I downloaded a fresh version of Galaxy with all stable updates. I've just come across a NameError in the upload.py tool. ---- Traceback (most recent call last): File "/home/rob/galaxy-dist/tools/data_source/upload.py", line 390, in <module> __main__() File "/home/rob/galaxy-dist/tools/data_source/upload.py", line 368, in __main__ dataset = from_json_string( line ) NameError: global name 'from_json_string' is not defined ---- A quick investigation led me to: from galaxy.util.json import * and from there to json.py. I compared this file with my previous version and note that there are quite a few changes. The problem seems to be that from_json_string() is not included in the __all__ list of public functions... can someone tell me if this is a bug/oversight or if I'm missing something? Cheers, Rob
