GoogleCL Docs Upload Fixed for Gdata 2.0.15 and 2.0.16

Months ago, we fixed Google Docs Uploads for GoogleCL folks who use python-gdata 2.0.12 through 2.0.14. Today, we tackled the problem for users of python-gdata 2.0.15 and 2.0.16.

A user sent in a patch that fixed the MIMETYPES error we were getting with 2.0.15 and 2.0.16. It looks like python-gdata moved away from declaring MIMETYPES where we were calling them from, so now we name them explicitly in googlecl/src/googlecl/docs/client.py.

That was a great start, but then we started getting a DocsEntry error and uploads still wouldn't work, so we delved further. Here's the error we got after fixing the MIMETYPES problem.

AttributeError: 'module' object has no attribute 'DocsEntry'

One of our earlier searches brought us to the same error posted on python-gdata's buglist.

Then, we found this blog post, by Demon Lord, where they had success replacing the string "gdata.docs.data.DocsEntry" with the string "gdata.data.GDEntry". We tried that throughout the file googlecl/src/googlecl/docs/client.py and sure enough, that fixed it!

We tested 2.0.0 through 2.0.4 to make sure that didn't break anything for those users and then tested 2.0.12 through 2.0.16 to make sure it worked on all the versions that should be able to upload docs. It does so it's now been committed.

MIMETYPES fix gives AttributeError: no 'DocsEntry'

The same gentleman who helped make it possible to fix the docs upload bug also suggested the start of a fix for the MIMETYPES bug we get with python-gdata versions 2.0.15 and 2.0.16 with the fix (with or without this fix, we can't upload docs via python-gdata 2.0.15 or 2.0.16, so the fix was still worth publishing).

The error I get now is:
AttributeError: 'module' object has no attribute 'DocsEntry'

A quick grep of the whole googlecl tree for the term "DocsEntry" shows me that it only exists in gdata versions 2.0.11 and 2.0.14. . . So why does GoogleCL call for it in the trunk/src/googlecl/docs/client.py file? The call for it seems to work with python-gdata 2.0.12 -- I can upload documents of txt and pdf types without a complaint about DocsEntry.

Edit: Resolved this issue and blogged about it here.

Testing GoogleCL Part 3

Apparently, you don't need to backslash the apostrophes in posts, though. Interesting.

If you can see this, then it worked again. Apparently, you need to put a backslash before a \! character, but then it shows the backslash, too. Also, as with the \! character in the post, I had to put a backslash before the apostrophe in my blog's title name (Let\'s Get Technical)

Python Gdata

Short version: To upload Google Docs with a service that utilizes python-gdata, use a version between 2.0.12 and 2.0.14. Keep reading for more details.

Credentiality and I spent a few hours on this tonight. Here's a brief history and a beautiful table to show you what to expect.

An SSL error occurs in a few platforms using gdata when you try to upload files to Google Docs and it doesn't appear to be limited to python-gdata. It may relate to this. Credentiality and I work on  GoogleCL sometimes, so we have all the python-gdata versions from 2.0.0 through 2.0.15 and test code with all of them, anyway. Here are some observations and what has worked for us so far.

In May 2, 2011, Google began to allow uploading "all file types" for non-premium users. Now, if you add a resumable uploader fix to a specific GoogleCL client.py file* and you use python-gdata 2.0.10 or 2.0.12 through 2.0.14, GoogleCL should upload a PDF to Google Docs successfully.

Without the resumable uploader fix, python-gdata 2.0.10 or 2.0.12 through 2.0.14 gives us this 403 error:

403, <errors xmlns='http://schemas.google.com/g/2005'><error><domain>GData</domain><code>ServiceForbiddenException</code><internalReason>Files must be uploaded using the resumable upload mechanism.</internalReason></error></errors>

When we use python-gdata 2.0.5 through 2.0.9 or 2.0.11, we get this 403.4 SSL error:

403, <errors xmlns='http://schemas.google.com/g/2005'><error><domain>GData</domain><code>ServiceForbiddenException</code><internalReason>403.4 SSL required</internalReason></error></errors>

The python-gdata versions before 2.0.5 can't upload PDFs to Google Docs, anyway. We get the following error for those:

{'status': 415, 'body': 'Content-Type application/pdf is not a valid input type.', 'reason': 'Unsupported Media Type'}

python-gdata 2.0.15 doesn't work with GoogleCL to upload to Google Docs, either. Currently, we get this error, which seems to be a GoogleCL error related to some change in gdata from 2.0.14 to 2.0.15:

from gdata.docs.data import MIMETYPES
ImportError: cannot import name MIMETYPES
