Protobuf 2.6.0 pip dependency conflict

[psypuff]

Since google-apputils was added as a dependency on 2.6.0 we have dependency conflict on python-dateutil, apparently google-apputils needs 'python-dateutil>=1.4,<2' but the latest public version is 2.2 which is needed and installed by other packages.

Current workaround is to downgrade python-dateutil to 1.5 but it'll probably break something sooner or later, any chance to loose a bit the requirements?

Thanks

FYI this is causing problems for gcloud-python, see
googleapis/google-cloud-python#215

@craigcitro FYI I saw you were a maintainer of google-apputils.

Do you know the reason for strange the dateutil requirement in setup.py:

REQUIRE = [
    "python-dateutil>=1.4,<2",
    "python-gflags>=1.4",
    "pytz>=2010",
    ]

It is causing some "upstream" problems in this library.

[craigcitro]

yes -- this is an unfortunate issue around being able to test with our internal versions of python-dateutil. there's a thread going, but no conclusion yet.

does anyone happen to know how big the API difference is between version 1.4 and 2+ of python-dateutil?

[dhermes]

Code docs list contact info for Gustavo Niemeyer.

@niemeyer would you be able to weigh in on the API difference between dateutil 1.4 and 2+?

UPDATE: I confirmed that Gustavo has handed off maintenance.

Code is hosted on LaunchPad.

Other member and PyPI owner is Tomi Pievilaeinen who has contact info on ActiveState.

OK, looking at our code using dateutil, i think we can just drop it.

let me at least ping the other thread, see if anyone has time to look at this.

[dhermes]

Will it build? If it BUILDs, everyone is happy 👍

[craigcitro]

i think i'll be able to get a fix out soon, stay tuned.

[dhermes]

w00t. Thanks for pushing through this.

[psypuff]

Yay, thanks! 👍

I had to downgrade my Brew installation of protoc to 2.5 because of this implicit dependency on an ancient version of python-dateutil. We're also using Boto, which requires a modern version of dateutil.

Since the only reason that google-apputils is being used is to get basetest, which is used only in test code, can the requirement be extracted from setup.py and put into test-requirements.txt?

[dhermes]

@georgevreilly See https://github.com/craigcitro/apitools/pull/9

[craigcitro]

... and we're fixed! i just pushed a new version of google-apputils, we should be up and running.

[dhermes]

w00t! I assume you're referring to: https://pypi.python.org/pypi/google-apputils/0.4.1

How does the Ubuntu / debian source process work?

[craigcitro]

yep, just pushed the new release, and now this package can install with no trouble.

i have no idea who/what controls the deb creation.

Thanks very much, Craig!

@craigcitro The Debian packaging for google-apputils-python is here: http://anonscm.debian.org/cgit/cloud/google-apputils-python.git. I've just updated it for 0.4.1 and uploaded it to the Debian archive.

[craigcitro]

wooooo thanks @edmonds !

[psypuff]

Thanks Craig! 😄
