Subject Re: [DISCUSSION] Ignite 3.0 and to be removed list
Date Fri, 21 Jun 2019 07:31:13 GMT
Hello Igniters,

I'd like to add my ¢2 considering Python thin client.

I think we should abandon Python 3.4, which was a precondition from
Ignite community when I started to work on `pyignite` a good year ago,
and update the minimum requirement to at least Python 3.6, or, better
yet, 3.7.

Reasons to do so:

1. Python 3.4 has reached its EOL this Spring. The final build was
released: March 18, 2019. PIP, setuptools, PyCharm are already dropped
their support for Python 3.4. In other words, bits have started to rot.

2. Python 3.4 builds against OpenSSL 1.0, while 3.5+ − OpenSSL 1.1. If
we intend to support TLS 1.3 encryption in Python thin client, we
should move on from Python 3.4.

3. The most important part for me as a developer: positive changes in
the language itself. To name only a few:

- `dict` and `OrderedDict` types was merged within one highly-optimized 
C implementation, 

- `typing` module (type annotations support) was built into the
language and significantly improved,

- string interpolation (so-called “f-strings”) and data classes was
introduced in 3.6.

If there is at least one good reason to support Python 3.4, I would
like to learn about it. Otherwise, the struggle for supporting the
outdated language version seems pointless to me.
