[Debian GNUstep maintainers] Bug#1050528: gnustep-base: autopkgtest needs update for new version of tzdata

[Paul Gevers]

Source: gnustep-base
Version: 1.29.0-6
Severity: serious
X-Debbugs-CC: tzdata at packages.debian.org

Control: affects -1 src:tzdata

Dear maintainer(s),

With a recent upload of tzdata the autopkgtest of gnustep-base fails in 
testing when that autopkgtest is run with the binary packages of tzdata 
from unstable. It passes when run with only packages from testing. In 
tabular form:

                        pass            fail
tzdata                 from testing    2023c-10
gnustep-base           from testing    1.29.0-6
all others             from testing    from testing

I copied some of the output at the bottom of this report.

Currently this regression is blocking the migration of tzdata to testing 
[1]. Of course, tzdata shouldn't just break your autopkgtest (or even 
worse, your package), but it seems to me that the change in tzdata was 
intended and your package needs to update to the new situation.

If this is a real problem in your package (and not only in your 
autopkgtest), the right binary package(s) from tzdata should really add 
a versioned Breaks on the unfixed version of (one of your) package(s). 
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.
