Move twill related code into separate package

[johnjiang]

Twill itself has not been updated in 6 years and is not compatible with python 3. This means that flask-testing will never be able to support python 3 as long as it depends on twill.

+1 to this. I'm quite stuck right now because this doesn't support Python 3

[jarus]

You are right. I think to replace twill with selenium would be a good step to python 3. There is space and time to discuss this.

[playpauseandstop]

Totally +1 to this. Today had same issue, when trying port my flask app with Flask-Testing in requirements to Python 3.

[johnjiang]

This is actually becoming more urgent since it looks like you can't even install twill through pypi now

 $ pip install twill
Downloading/unpacking twill
  Could not find any downloads that satisfy the requirement twill
  Some externally hosted files were ignored (use --allow-external twill to allow).
Cleaning up...
No distributions at all found for twill

Which means that you can't install flask-testing.

To get around it I had to do:

pip install twill --allow-external twill --allow-unverified twill

Edit: I think this may be related to pip 1.5.

BACKWARD INCOMPATIBLE pip no longer will scrape insecure external urls by default nor will it install externally hosted files by default. Users may opt into installing externally hosted or insecure files or urls using --allow-external PROJECT and --allow-unverified PROJECT. (Pull #1055)

Just wanted to add my +1 to this and the move to selenium over twill.

+1 for this issue.

It makes it unusable with tox :(

Hey guys, I have created a branch which removes twill and makes the code fully Python 3 compatible. You can find it here https://github.com/fgimian/flask-testing/tree/python3

To use my version in your requirements.txt, simply add the following:

git+https://github.com/fgimian/flask-testing.git@python3

I'm happy to send a pull request on this but seeing as how I completely removed twill, I doubt it would be merged 😄

Cheers

@jarus If I implement a branch which supports Python 3 but disables twill when running under Python 3, would you consider merging it? This shouldn't be hard to do and I can update the docs to mention that twill only is supported under Python 2.x 😄

Please let me know mate

Cheers
Fotis

[jgumbley]

Would be nice to get this.

[jarus]

Would be realy nice.

[fgimian]

No worries guys, I'll get onto this over the next few days. Thanks for your support! 😄

[fgimian]

Hey guys, just submitted my pull request 😄

Please don't hesitate to ask any questions or let me know if you see any problems.

The Travis builds for Flask 0.8.1 and 0.9 are failing on Python 3.3 as it seems only Flask 0.10.1 supports Python 3.3. I'm not aware of a way to setup .travis.yml to avoid testing a particular env for specific Python versions. If anyone knows how to do this, that would be greatly appreciated.

Cheers

@fgimian See http://docs.travis-ci.com/user/build-configuration/#The-Build-Matrix

[fgimian]

Thanks @cvrebert, I'll try to fix it up now 😄

[fgimian]

I've just made a second commit to the same branch which repairs the Travis issue and now the entire build is passing. Thanks for your help Chris! 😄

Merged into master. Thanks for your contribution.
