I expect

travis gate to work with py26

Instead

I get the following error when installing pytest

...
cmdargs: ['/home/travis/build/prometheus/client_python/.tox/py26/bin/pip', 'install', 'coverage', 'pytest', 'unittest2']
...

Collecting py>=1.5.0 (from pytest)

Looks like something broke on Travis's end in the past month.

Pytest and its dependency py have dropped support for Python 2.6 because it's been EOL for four years meaning it hasn't received security updates, and it's also little used so it's about time to drop it. They also dropped support for Python 3.3 which is also EOL and little used.

Here's the pip installs for prometheus_client from PyPI for the last month (via pypinfo --percent --pip prometheus_client pyversion).

python_version percent download_count
2.7 61.2% 44,829
3.6 21.0% 15,367
3.5 13.5% 9,890
3.4 4.0% 2,947
3.7 0.2% 116
2.6 0.1% 87
3.3 0.1% 48
3.2 0.0% 1

I suggest client_python also drops 2.6 (3.3 is already dropped).

Do we know if there are any popular OSes that still use 2.6, such as RHEL?

RHEL 6 ships with 2.6 and RHEL 5 ships with 2.4.

But a secure Python can be installed using SCL:

Another way to close this issue.

@hugovk: I still have to run prometheus_client on RHEL6 too

Do you have a plan to upgrade RHEL/Python?

@hugovk I got a bunch of customers with various RHEL versions including 6, so no dropout for now :(

@brian-brazil closing for now
@hugovk you can create a new ticket for deprecating py26. It will surely be useful in the near future!
