kgio, raindrops, unicorn and Ruby 2.2.0-preview102 Oct 2014
I was trying to upgrade Codetriage to use Ruby 2.2.0-preview, the latest Ruby version. The project is hosted on Heroku. So to upgrade I changed Ruby version in Gemfile:
# Gemfile ruby '2.2.0'
After that I tried to do bundle install:
And boom. Got error:
Gem::Ext::BuildError: ERROR: Failed to build gem native extension. /Users/prathamesh/.rbenv/versions/2.2.0-preview1/bin/ruby -r ./siteconf20141002-23644-1wbcnhc.rb extconf.rb ..... creating Makefile make "DESTDIR=" clean make "DESTDIR=" compiling accept.c In file included from accept.c:90: /Users/prathamesh/.rbenv/versions/2.2.0-preview1/include/ruby-2.2.0/ruby/backward/rubysig.h:14:2: warning: rubysig.h is obsolete [-W#warnings] #warning rubysig.h is obsolete ^ accept.c:101:2: error: use of undeclared identifier 'TRAP_BEG' TRAP_BEG; ^ accept.c:103:2: error: use of undeclared identifier 'TRAP_END' TRAP_END; ^ 1 warning and 2 errors generated. make: *** [accept.o] Error 1 make failed, exit code 2 Gem files will remain installed in /Users/prathamesh/.rbenv/versions/2.2.0-preview1/lib/ruby/gems/2.2.0/gems/kgio-2.8.0 for inspection.

kgio gem is dependency of
unicorn which is the application server
used by Codetriage. Looking at
documentation of kgio, I
found out that latest gem version is
2.9.2 while as our Gemfile.lock
The exact changelog entry is:
commit 6243d74cc8296d40a66969594e42963c896968ee Author: Eric Wong <firstname.lastname@example.org> Date: Sat Feb 15 09:21:07 2014 +0000 kgio 2.9.2 - avoid deprecated/removed function This release is for compatibility with future releases of mainline ruby, as rb_thread_blocking_region is removed in r44955 of ruby trunk This also avoids deprecation warnings fo rb_thread_blocking_region 2.0 and 2.1.
So looks like this is the version that should be used with new versions of Ruby.
2.9.2 for kgio gem in Gemfile.lock:
# Gemfile.lock multi_json (>= 1.5) kgio (2.9.2) kramdown (1.3.2)
After updating Gemfile.lock and running
bundle install again, it
completed successfully. I was able to run the app using Unicorn on
See this PR to see more details.
After i submitted the PR, the tests could not be run on Travis because
of error related to installing
raindrops gem which is also
dependency of Unicorn:
Gem::Ext::BuildError: ERROR: Failed to build gem native extension. /home/travis/.rvm/rubies/ruby-2.2.0-preview1/bin/ruby -r ./siteconf20141002-1677-1g08hg8.rb extconf.rb .... linux_inet_diag.c:28:2: error: ‘TRAP_BEG’ undeclared (first use in this function) linux_inet_diag.c:28:2: note: each undeclared identifier is reported only once for each function it appears in linux_inet_diag.c:30:2: error: ‘TRAP_END’ undeclared (first use in this function) linux_inet_diag.c: At top level: linux_inet_diag.c:22:1: warning: ‘rb_thread_blocking_region’ defined but not used [-Wunused-function] make: *** [linux_inet_diag.o] Error 1
I did not had this problem locally when I did bundle install. But to
fix this, I again checked
raindrops. Turns out that the latest release of
0.13.0 whereas Gemfile.lock was still pointing to
this release is specific to 2.2.0 according to changelog.
commit d24900b305a02cdedc4a532253798117f9686b5c Author: Eric Wong <email@example.com> Date: Tue Feb 18 20:57:46 2014 +0000 raindrops 0.13.0 several minor fixes and improvements Most notably, this release is necessary for Ruby 2.2 (dev). Thanks to Koichi Sasada for the bug report! Eric Wong (5): Rakefile: remove raa_update task last_data_recv: do not assume Unicorn includes all constants raindrops.gemspec: add wrongdoc dev dependency linux_inet_diag: fix Ruby 2.2 (dev) build license: use LGPLv2.1 or later (was LGPL (2.1|3.0)-only) Hleb Valoshka (1): Remove Scope IDs from IPv6 addresses.
Again applied same fix by changing Gemfile.lock and now raindrops is installed on Travis.
