ruby¶
Testsuite¶
The testsuite is run on build. Some tests fail if run as root:
compile as an unprivileged user and use autopkgtest --user.
To run a subset from the currently built ruby:
tool/runruby.rb test/runner.rb 'test/net/*'
tool/runruby.rb test/runner.rb -n 'TestNetHTTPS#test_session_reuse_but_expire'
tool/runruby.rb test/runner.rb -n 'TestGemSpecification#test_date_equals_time' test/rubygems/test_gem_specification.rb
In a GMT+X timezone, TestGemSpecification#test_date_equals_time is
always failing (with a 1-day mismatch), from stretch to bookworm.
This doesn’t trigger in a typical buildd/pbuilder environment. Build
with TZ=UTC as a work-around.
ruby2.7/bullseye will produce many errors for
test/ruby/test_time_tz.rb if ruby-tzinfo is installed.
Uninstall it first.
Build caveats¶
ruby2.x appears to be usually built with:
gbp buildpackage ... --git-builder=git-pbuilder
If you want to have a working compiled directory, e.g. to quickly run and fix individual tests, this gets tricky.
Building from Git (without the tarball timestamps), or rebuilding
twice (as the first build enables make distclean), triggers a
different build path which requires “host ruby” to be already
installed, or files to be regenerated with different versions of tools
such as bison. If you don’t want that:
tar --strip-components 1 -xf ../ruby2.*.orig.tar.*
# or
touch prelude.c miniprelude.c id.* probes.dmyh *.inc parse.c enc/trans/newline.c # buster
gbp buildpackage ...
Even without that, building leaves modified and extra files, making it
hard to reset to a clean state in a dpkg-source extract, so better
use gbp. Note that buster/bullseye’s gbp buildpackage silently
exits if pristinetar is not present, so install it.
Freexian CI¶
autodep8
is installed and triggers gem2deb-test-runner while testing rdeps
Ruby packages; this adds generic tests even if there’s no
debian/tests/.
autodep8 was forked to support jessie, see also
