[Fix]
- * Changes
- - Trusty: drop python2 binaries in trusty (was not released there yet)
- Xenial has those already published, we are not gonna take them away.
- see [1]
- - Trusty: adapt python-six dependency to match what is really needed
- and available in Trusty. Xenial has a version higher than that so
- don't bother modifying it there.
- see [2]
- - Trusty and Xenial: adapt python-libnacl dependency by backporting
- upstream fix on a too struct version requirement.

[Regression Potential]
- * Lets split this section for Trusty and Xenial.
- a) Xenial only gets slightly relaxed version dependencies, those should
- allow pymacaroons to run, but actually never cause any additional
- issues.
- b) Trusty this isn't released in trusty at all yet (still in proposed
- intentionally). Therefore this is one of the few cases I'd call
- regression risk next to zero. If anything then issues out of the py2
- removal not working as expected, but it seems to be ok in build and
- tests.

On the extended testing for the SRU in bug 1817665 we found that there
are a few dependency issues that need to be fixed.
Affects X&T:
python-libnacl - depends on <1.4 but xenial (and trusty soon) have 1.4.5
Fix by importing
https://github.com/ecordell/pymacaroons/commit/3924d5b56c42234d0bff3820bc4cb6c4d3f74d8d
Affects T:
python-six - depends on >=1.8.0 - but trusty is on 1.5.2 still
We evaluated if we need to backport six as well (a lot or reverse deps).
We found that the usage of pymacaroons is actually ok with 1.5.2
Upstream regularly bumps the dependency level as well as some changes that
got added but in the meantime removed (e.g. the serialization).
Eventually only two use cases for python3-six are left
- pymacaroons/caveat_delegates/encrypted_first_party.py:4:from six import
iteritems
- pymacaroons/utils.py:5:from six import text_type, binary_type
None of these are changed in six between 1.5.2 and 1.8 checked by
Odd_Bloke, ahasenack and me.
Affects T:
python2 - we don't need/want python2 support in this, so since we don't
usually exercise and have no interest in supporting the python2 paths lets drop
them from pymacaroons in trusty (where they are not published yet).
