Message #5 received at submit@bugs.devuan.org (full text, mbox, reply):

Package: greylistd
Version: 0.8.8.7
Severity: grave



The hash() function used to hash triplets in python3 has a different
behaviour that the python2 version. 

py3 hash() is salted, so the hash it produces for the same input text differs between runs.

That produces two problems in greylistd:
- multiple entries added to the lists 
- checks produces different keys

To reproduce:
- start greylistd

- greylist clear
- greylist list --white (verify is empty)
- greylist add --white a.com
- greylist list --white (verify a.com is in wl)
- greylist check a.com (should be white)

- restart greylistd
- greylist list --white (verify a.com is in wl)
- greylist check a.com (returns grey, should be white)

Thank you.

However, greylistd is not forked in Devuan and we use Debian's packages directly
without recompilation. Please report this issue to Debian's BTS to be addressed.

Thanks.

Not at all.

When you have, maybe you could add the Debian bug number here so we can track it
easily?

Thanks
