Bad write retry error with python 2.7.10

[Nagriar]

When I try to execute

def test_network(self):
        batch = []
        for i in range(1, 3000):
            batch.append({'action': 'addObject', 'body': {
                'test1': 'aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa'
            }})
        self.index.batch(batch)

I receive the error: AlgoliaException: Unreachable hosts: {'YLGNV73XLW-2.algolianet.com': "[('SSL routines', 'ssl3_write_pending', 'bad write retry')]", 'YLGNV73XLW.algolia.net': "[('SSL routines', 'ssl3_write_pending', 'bad write retry')]", 'YLGNV73XLW-3.algolianet.com': "[('SSL routines', 'ssl3_write_pending', 'bad write retry')]", 'YLGNV73XLW-1.algolianet.com': "[('SSL routines', 'ssl3_write_pending', 'bad write retry')]"}

If I use python 3.4, the issue is fixed, it's maybe related to https://hg.python.org/cpython/rev/60310223d075/

Interesting issue 😮

The issue comes from PyOpenSSL and Python 2.7
It works well on python 2.7.10 without PyOpenSSL installed.

💃

We use PyOpenSSL on Python 2.X for the SNI Support... :(

[Nagriar]

Why 2.6 is working on travis? it's a regression?

[dethi]

https://docs.python.org/2/library/ssl.html#ssl.HAS_SNI
So PyOpenSSL is only needed for Python 2.6 because Python 2.7.9+ comes with SNI Support :)

Interesting :) So do you think we could depend on it based on the version of python?

[dethi]

@redox Well, I tried last month to use "package_name;python_version >= 'X.X' but without success. pip has some issue with this syntax and many OS are shipped with old version of pip, which is bad...

@Nagriar yes I think, but I can't find any opened issue about it.

[Nagriar]

The fix is on the master branch of urllib3 (https://github.com/shazow/urllib3/blob/master/CHANGES.rst#dev-master). We just need to wait the release to fix this issue.

[dethi]

Cool :)

[Nagriar]

💥 Version 1.13 released

@Nagriar @dethi Is there a workaround for those who can't upgrade urllib3 because of dependency issues elsewhere?

[dethi]

@dustincoates if you can uninstall PyOpenSSL, it should work.

[dustincoates]

Thanks @dethi. I'll see if that's an option for them.
