Commit 19c5f32 fixed the last point on the PR description, which I have now removed. Also tests are able to download the latest SQLite database and therefore run faster.

Down to 4 failures, I may need some help with those.

Wow - thanks so much @nsoranzo - this is awesome.

Trying to pick it up from here - I can replicate broadly the behavior here #765 with Python 3 now - the toolbox loads fine with Python 3 and planemo serve but there are no tests with planemo test. This is at least one of the 4 remaining errors - this one about expecting a test failure and not finding one.

Thanks! I tried to restart the test build a few times, but it keeps stalling at "Test testing a simple GA workflow with Galaxy" test.

Working on it - locks up pretty quickly here. Looks like the output is fetched from Galaxy but nothing ends.

Maybe killing the server and re-joining is broken in Python 3... hmm...

This piece of code in galaxy-lib I suspect is the problem:

    if path is not None:
        properties["path"] = path
        f = open(path, "rb")
    else:
        f = StringIO(content)

    try:
        contents = f.read(1024 * 1024)
        filesize = 0
        while contents != "":
            checksum.update(contents)
            filesize += len(contents)
            contents = f.read(1024 * 1024)
    finally:
        f.close()

@jmchilton Given the file is opened in binary mode, and you want the raw length, then from io import BytesIO seems a better bet than StringIO here.

@peterjc Yup - that was exactly the fix - galaxyproject/galaxy-lib#93. I should have linked it against this PR.

I think the only broken test here is a test that has been broken in master as we worked on this. Local conda packages maybe broke during the big galaxy-lib update or maybe broke due to Conda changes elsewhere.

The jmchilton branch Travis finishes faster:

Thanks so much @nsoranzo - this is really awesome. I really appreciate all the work you put into this.
