[Pkg-openssl-devel] Bug#907031: python3.7: autopkgtest needs update for new version of openssl

[Paul Gevers]

Source: python3.7
Version: 3.7.0-5
X-Debbugs-CC: debian-ci at lists.debian.org, openssl at packages.debian.org

Dear maintainers,

With a recent upload of openssl the autopkgtest of python3.7 started to
fail in testing. I copied the some of the output below.

Currently this regression is contributing to the delay of the migration
of openssl to testing [1]. Of course, openssl shouldn't just break your
autopkgtest (or even worse, your package), but it seems to me that the
change in openssl was intended and your package needs to update to the
new situation. If needed, please change the bug's severity.

If this is a real problem in your package (and not only in your
autopkgtest), the right binary package(s) from openssl should really add
a versioned Breaks on the unfixed version of (one of your) package(s),
hence I added a blocking relation on the openssl bug that tracks that.
Note: the Breaks is nice even if the issue is only in the autopkgtest as
it helps the migration software to figure out the right versions to
combine in the tests.

A quote from the openssl maintainer about the openssl update:
"
This is probably the result of the default openssl.cfg now having:
[system_default_sect]
MinProtocol = TLSv1.2
CipherString = DEFAULT at SECLEVEL=2

Where the SECLEVEL 2 requires a 112 / 2048 bit security level.
"
