Package: ruby-redis
Version: 6.0.0-1
Severity: serious
Dear Maintainer,
ruby-redis 6.0.0-1 fails to build from source in unstable now that
ruby-redis-client 0.31.0-1 is in unstable (accepted 2026-10-06). The
same incompatibility makes ruby-redis unusable at run time. I set the
severity to serious because the release critical issues document says:
"Packages must be buildable within the same release."
The requirement comes from upstream. redis.gemspec in
ruby-redis_6.0.0.orig.tar.gz says:
line 47: # Pinned to an exact redis-client version: redis-rb couples
tightly to redis-client internals
line 52: s.add_runtime_dependency('redis-client', '0.30.1')
Build failure (sbuild, unstable chroot, ruby-redis-client 0.31.0-1
installed, finished 2026-10-06T18:07Z, Fail-Stage: build):
Checking Rubygems dependency resolution on ruby3.3
Could not find 'redis-client' (= 0.30.1) among 117 total gem(s)
(Gem::MissingSpecError)
dh_auto_test: error: dh_ruby --test returned exit code 1
Run time reproduction in a clean unstable chroot (apt-get install ruby
ruby-redis, then ruby -e "require 'redis'"):
Could not find 'redis-client' (= 0.30.1) ... at:
/usr/share/rubygems-integration/all/specifications/redis-6.0.0.gemspec
(Gem::MissingSpecError)
cannot load such file -- redis (LoadError)
The installed redis-6.0.0.gemspec contains:
s.add_runtime_dependency(%q<redis-client>.freeze, ["= 0.30.1".freeze])
The binary package declares (apt-cache show ruby-redis in unstable):
Depends: ruby:any, ruby-redis-client (>= 0.30.1)
so apt accepts ruby-redis-client 0.31.0-1, while RubyGems rejects it.
debian/control in the source package lists only Depends: ruby:any, so I
assume the redis-client dependency is generated during the build; I have
not checked how the exact upstream requirement becomes (>=).
Testing still has ruby-redis-client 0.30.1-1 and is consistent. The
tracker shows autopkgtests for ruby-redis, ruby-redis-client,
ruby-redis-cluster-client and ruby-sidekiq triggered for 0.31.0-1, with
no results yet.
The newest upstream redis gem is 6.0.0, released 2026-07-31
(rubygems.org versions API), which is the version already packaged. So
there is no newer redis release available to package for redis-client
0.31.0. I did not check for unreleased upstream work.
Impact: packages that build or test with the redis gem fail in unstable.
I noticed this while updating ruby-classifier-reborn, whose Redis tests
error with NameError: uninitialized constant ...::Redis instead of skipping.
I do not know which side should change (keeping ruby-redis-client
0.31.0-1 out of unstable until a compatible redis release exists, or
another solution), so I leave that to you. I did not find an existing
bug for this: src:ruby-redis-client has no reports, and src:ruby-redis
has only #1093118, whose title concerns ruby-fakeredis.
Thank you for maintaining these packages.
