[Python-modules-team] Bug#886291: pycryptodome: python3-pycryptodome contains pycryptodomex instead of pycryptodome

[Alexis Murzeau]

Source: pycryptodome
Version: 3.4.7-1
Severity: normal

Dear Maintainer,

While packaging a python program (streamlink) which use pycryptodome
with a fallback to pycrypto, I found that the package
python3-pycryptodome contains the pycryptodomex module instead of
pycryptodome.

This is because the packages python3-pycryptodome and
python-pycryptodome are built by creating the ".separate_namespace" file.

This ".separate_namespace" file switch the built python module from
pycryptodome to pycryptodomex.

So python3-pycryptodome and python-pycryptodome packages contain
pycrytodomex module instead of pycryptodome.

The difference between both is that pycryptodome installs its modules
under the Crypto package and pycryptodomex installs its modules under
the Cryptodome package.
Which means pycryptodome can be drop-in replacement for pycrypto but
pycryptodomex cannot.

I suggest that:
 - Existing pythonX-pycryptodome packages build pycryptodome instead of
   pycryptodomex,
 - Add new binary packages pythonX-pycryptodomex containing
   pycryptodomex.


As pycrytodome contains the same python package (Crypto) as pycrypto,
the two package are in conflict. I'm not sure what's the best way to
handle that:
 - Don't make any pythonX-pycryptodome packages and just rename the
   existing one to pythonX-pycryptodomex (so the other name is still
   available in case it becomes needed)
 - Make a conflicts dependency on pythonX-crypto in pythonX-pycryptodome
 - Eventually think about a transition from pycrypto to pycryptodome
   (pycrypto seems dead, last release was in 2013 according to github)


As a side note, I also found that the built manpages are not packaged in
any of the binary package. I don't think it's expected as d/rules
explicitly builds manpages.

Thanks in advance,

Alexis Murzeau
