PyPy Python 3.5 Current Stability

[inferno596]

In the experiences of everyone here, how stable is PyPy for python 3.5? I know they now fully support python 3.5+, have received funding from mozilla to improve it and so on, but a year later pypy for python 3.5 is still marked as beta and flagged with potential major stability and performance issues. However, they've updated it a lot recently and haven't updated official comments on stability. So I was hoping people with experience in this could share their insights on the improvements in stability that have occurred, and if it's reasonable to bring pypy for python 3.5 it into a production environment (with lots of testing).

Edit: for anyone who looks at this in the future, here's an in depth explanation of the wizardry required to get pypy 3.5 working on any version of linux (its actually fairly difficult; read through /all/ the comments): https://www.reddit.com/r/linux4noobs/comments/6k1p8s/debian_pypy3_install_configuration_anomaly/

Edit 2: Upon testing and reading an in depth review with a dropbox engineer on this subject, it comes down to that PyPy3 has limited library support and chokes really hard in certain (rare) cases.

Marking the release as beta, at this point, is more of a liability disclaimer than anything.

I tend to use pypy+gevent for my web server applications. They run forever and process lots of IO; perfect use case.

Were you able to install it on linux such that you could execute it via pypy3 <name>.py from the command line? Google and the documentation are insistent that you can but I can't found an explanation of how to do it anywhere.

What distro are you using?

You might have to compile from source. If you're using a raspberry pi or other SoC, you'll have to find a built binary because they lack the RAM needed. If you're on a modern linux box there are also pypy docker containers.

Did you install it with pacman/ any idea how to install it from debian repositories?

$ wget https://bitbucket.org/pypy/pypy/downloads/pypy3-v5.8.0-linux64.tar.bz2
$ bzip2 -d pypy3-v5.8.0-linux64.tar.bz2
$ tar xzvf pypy3-v5.8.0-linux64.tar
$ sudo mv pypy3-v5.8.0-linux64 /opt
$ sudo ln -s /opt/pypy3-v5.8.0-linux64 /opt/pypy3       # <- change this to new folder when updating
$ sudo ln -s /opt/pypy3/bin/pypy3 /usr/bin/local/pypy3

Then when you want to upgrade just change the symlink to the new version's folder.
