Two of the interpreters we ship are quite problematic in this regard.
### Python 2.6
- virtualenv 16.x dropped support for 2.6 and we dirty patched it back
- tox 3 dropped support for 2.6
- pip/setuptools dropped support for 2.6 and our patched virtualenv
uses an older version of pip and setuptools to make work
However, I know there are developers who use Python 2.6 in Fedora
(namely because their software maintains RHEL 6 compatibility).
I propose that we indicate on Fedora Developer Portal that Python 2.6
is provided as is and that it may not work with virtualenv/tox. We
maintain the current patch of virtualenv at least for the lifetime of
Fedora 29, but if an upgrade of virtualenv is done, we ditch that
patch from Fedora 30+.
We also mark it deprecated and schedule the removal for EPEL 6 EOL
(AFAIK late 2020).
### Jython
- virtualenv somehow works but is not officially supported
- pip is not supported and has hesisenbugs
I know nobody who uses Jython with virtualenv and tox.
I propose that we indicate on Fedora Developer Portal that Jython is
provided as is and that it may not work with virtualenv/tox.
(No scheduled removal.)
Thoughts?
Sounds reasonable. I just think before any code changes, we should also
add a section to the portal on how to use virtualenv/tox with the old
versions. The workaround is not pretty, but people shouldn't need to
rediscover it.
Sure thing. There will be no code changes yet. The scope is as follows:
1 mark CPython 2.6 an Jython with (*) on the portal,
describe in a footnote (or similar) how to deal with that,
recommend virtualenv<16 / tox<3 installed in another virtual
environment (extends [1]).
2 do no code changes at all
3 once the next major virtualenv is released, only update it in 30+
and remove the crazy patch
4 once EPEL6 is EOL, retire python26 from devel Fedoras
(and remove the crazy patch if 3 haven't happened yet)
