Add Python 3 support

[themartorana]

This is the only thing left on our systems requiring Python 2. If I have time I'll run a 2to3 pass across it and see what happens.

Thanks!

It would be nice if in the meantime, someone added this to the docs that it's not 2.4+ but any Python 2 version. :)

Thanks. We'll update the docs. Also we will have a Python 3 version before Python 2 end of life.

Hi Team,

Is there any update / luck ?
We were trying to migrate from python2 to python3 and made python 3.6.9 as default and tried to run scalyr-agent.. But it failed due to the compatibility issue (python-2). Is there any fix/workaround to run it with python3 ?

@echee2 - Pls find the error below:

user@ipaddress$ sudo systemctl status scalyr-agent-2

Thanks!

hey, any luck with 2to3 ?.. I tried didn't work

[themartorana]

I'd like to bump this. Python 2 is disappearing from OS package managers. Thanks.

Pip is getting louder, too:

DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020.
Please upgrade your Python as Python 2.7 is no longer maintained.
pip 21.0 will drop support for Python 2.7 in January 2021.
More details about Python 2 support in pip can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support
pip 21.0 will remove support for this functionality.

Hi all!

Apologies for the lack of updates to this issue -- The Scalyr Agent has supported Python 3 (>= 3.5) since its v2.1.1 release on March 30, 2020. If you are presently running a v2.1.x release, you can switch the version of by executing the scalyr-switch-python command. For example,

$ sudo scalyr-switch-python python3
Switched agent to python3
If you have an existing instance of scalyr-agent-2 process running, you need to restart it for this change to take an affect.
You can do that by running '/etc/init.d/scalyr-agent-2 restart' command.
Agent switched to python3.

Hope this helps!
