Moving over to Leap as this test is still red and getting rails to work sucks big time still.

The work flow that works is

# zypper -n in -C "rubygem(rails)" # zypper in gcc make ruby2.5-devel libxml2-devel glibc-devel libxslt-devel sqlite3-devel $ rails new mycoolapp --skip-bundle --skip-test $ cd mycoolapp $ bundle config build.nokogiri --use-system-libraries $ bundle install --path vendor/bundle $ rails server -b 0.0.0.0

That is far away from obvious and plug&play, at least not to me. So question to the rails folks. Is that work flow expected and well known? If not, how about documenting it in the wiki and/or release notes?

Moreover, can we make that easier? For example, there already is a devel_ruby pattern. Would it make sense to just add the aforementioned devel package requirements to this pattern, so instead of installing the rails gem we document installing the pattern instead?

1. You should *not* build all those gems via bundler. those gems are all there via system gems already. you pass --skip-bundle to tell it "do not run bundle install" ... but then manually do the step you just told it not to. 2. no we can not ... because you explicitely skip the system nokogiri with your bundle install. one could maybe patch the template files that rails uses but tbh ... we would need this "use system libraries" with so many libraries, maybe some which we dont even know about. that this is tedious. and some of the packaged gems we actually had to patch to allow building with system copies. 3. my steps: $ zypper in --recommends 'rubygem(rails)' 'rubygem(sqlite3)' 'rubygem(puma)' $ rails new mycoolapp --skip-bundle --skip-test $ cd mycoolapp $ export RAILS_ENV="production" $ rails server WARNING: Nokogiri was built against LibXML version 2.9.7, but has dynamically loaded 2.9.8 => Booting Puma => Rails 5.1.5 application starting in production => Run `rails server -h` for more startup options Puma starting in single mode... * Version 3.11.2 (ruby 2.5.0-p0), codename: Love Song * Min threads: 5, max threads: 5 * Environment: production * Listening on tcp://cubes:3000 Use Ctrl-C to stop ^C- Gracefully stopping, waiting for requests to finish === puma shutdown: 2018-04-24 10:22:48 +0000 === - Goodbye! Exiting this was on TW ... but basically should work the same on L150 we probably should add puma and sqlite3 to the recommends list. installing rails without the --recommends is a bit tedious but we do *not* want to add requires for all the other things because it is possible to create rails apps without using the recommended libraries. so moving the recommends to requires would be wrong. Adam: This has *nothing* to do with packaging rails apps. So a totally unneeded comment. -- You are receiving this mail because: You are on the CC list for the bug.

I can't speak for all ruby developers, but I have done enough Rails to have my own opinion.

I can't imagine the situation where I would use a distro packaged Rails.

I only need:

- ruby - rubygem-bundler

If you are fine with a) having all the devel packages on your host b) you are fine to having to redo all the fixes that we might have in our gem based packages (e.g. I had a seed-fu fix for a while) c) you are fine with not getting security and other bugfix backports. I totally agree for just installing ... bundle install is so much easier. sadly it totally sucks for maintenance. (In reply to Duncan Mac-Vicar from comment #13)

I agree with Ludwig, the steps on -devel packages are confusing, but OSX users have it worse, and the majority of Rails developers probably use Macs.

yes ... that's why we have so many intree copies of C libraries in Gems... the worst is the libv8 gem ... which is a complete libv8 runtime repackaged as gem. If you are lucky the gem upstream updates the copy of the C library ... and if you are even more lucky ... you can actually update to that to the version with the fixed intree copy. Now you could argue ... "I just build against the system copy" ... if the gem supports it.

For example, as Ludwig described, the pattern could install the devel packages of the most important gems, but additionally, it could install something in the environment that sets NOKOGIRI_USE_SYSTEM_LIBRARIES=1.

This env var is just the same his bundle config cmdline. If you don't want to use the rpmified gems. Feel free. But this bug is not about that. your use case is just working fine. There are users who want to use rpmified rails. And we need it working for rails apps that we ship. So can we focus on that for now? -- You are receiving this mail because: You are on the CC list for the bug.

Things get tricky when you move development, say to Tumbleweed, and you have multiple projects with multiple targets... that's when things really go off the rails (pun intended ;-). After a decade of doing Rails on *SUSE* distros, the only solution that consistently works for me, is rvm for dev, and carefully crafted Gemfiles that match upstream packaging. Rvm is the saving grace that's allowed working on SLES12 projects with Ruby 2.1, projects running in Heroku on Ruby 2.4, new projects on Ruby 2.5, all without overpopulating my system with unnecessary libraries. If there's interest in making life easier for Ruby devs, what would help is packaged rvm builds for every Ruby version (as, 2.1 for example, no longer builds on Tumbleweed). (Of course this is all a digression from the original bug topic, sorry Dim*.) -- You are receiving this mail because: You are on the CC list for the bug.
