[bug#39028] [PATCH] gnu: Add python-asyncssh and dependencies

[zimoun]

Hi Lars-Dominik,

Thank you for this patch.

Usually, several packages are added with a series: one new package in
one patch. Could you split this big patch into 6 patches? Or explain
why it is a big one.

Thank you in advance.


All the best,
simon

[bug#39028] [PATCH 5/7] gnu: python-cryptography: Update to 2.8

[Lars-Dominik Braun]

Hi,

> Hello Braun, I have pushed the previous 4 patches into master, thank you!
thanks.

> This is not a small change for me, as 'guix refresh -l python-cryptography' says:
>   Building the following 167 packages would ensure 367 dependent packages are rebuilt...
True, I did not check that, my bad. Would it be acceptable to package an older
version of asyncssh compatible with python-cryptography 2.7?

> And I'm not sure about disable tests in python-pyopenssl (in the next
> patch), maybe we should update it to 19.1.0.
Nope, does not fix these three testcases for me.

Hi,

here’s an updated patch that adds python-asyncssh with a patch that restores
python-cryptography-2.7 compatibility until 2.8 hits master.

[bug#39028] [PATCH] gnu: Add python-asyncssh

[Lars-Dominik Braun]

[-- Attachment #1.1: Type: text/plain, Size: 228 bytes --]

Hi again,

since master now has python-cryptography==2.9, we can safely add
python-asyncssh without any custom patches. The attached patches first update
python-gssapi (a dependency) and then add python-asyncssh.

Cheers,
Lars

Hi!

This looks good to me, I tweaked the module (ssh seemed more
appropriate) and indentation, and pushed to master as
48dec2e04efdc764e16828fb7837ca58064f3cbe.

Thanks,

Chris
