Error loading nokogiri when starting compiled binary #151

I am having troubles packing new rails application (generated just with rails new) which has dependency to nokogiri . I have tried configuring bundler options in compiler.rb with no success, tried any combinations of those:

      @utils.run(local_toolchain_env, @bundle, 'config', 'build.nokogiri', '--use-system-libraries', "true")
      @utils.run(local_toolchain_env, @bundle, 'config', 'set', 'deployment', "true")
      @utils.run(local_toolchain_env, @bundle, 'config', 'set', 'without', "'development test'")

Log message:

/__enclose_io_memfs__/local/vendor/ruby/2.7.0/gems/activesupport-6.0.3.5/lib/active_support/dependencies.rb:324:in `require': cannot load such file -- nokogiri/nokogiri (LoadError)

Note: If I dont use change bundler config I get the same error for sqlite3 gem.

Env info:
rubyc - latest master
os - 20.04.1-Ubuntu
ruby - 2.7.1 (rbenv)
rails - 6.0.3.4

@tonchev-ivan did you remove bootsnap from your rails app?
Bootsnap doesnt work in ruby packer and it breaks native extensions loading.

@omohokcoj I have removed bootsnap but I'm still getting an error on macOS.

@kritik it looks like you need to remove the following lines from the complile.rb file:
motor-admin@dd10cc2#diff-a67b64a1d376c4e42cc056616662c72abd161952b3799ced47c68a4a0c05db0aR332

You can try my working ruby-packer fork https://github.com/motor-admin/ruby-packer - https://github.com/motor-admin/motor-admin has been packed into a single binary with it without any issues.

@omohokcoj Thanks. That works much better. But why did you change binaries?

@kritik I assume you're referring to the linked extensions replaced in the ruby-packer fork?
I compiled pg and mysql2 native extensions using static linker to make the executable even more portable and not depend on the libpq and libmysqlclient installation on the system (so no need to ask users to run apt-get install libpq-dev in order to run the executable).

@omohokcoj my nokogiri problem has been resolved but I see another C-extension issue. Any idea how to resolve this one?

@kritik ruby packer packs compiled dynamic libs (.so for linux and .bundle for macos) into a squashfs - but the problem is that dlopen doesn't work in the virtual filesystem.
So the solution was to copy .so .bundle files into the temp folder on disk to make the loading of dynamic libraries possible from there - but it looks like the ruby-packer C code responsible for this has a bug and sometimes files are not copies/loaded.

To fix that I had to override the Kernel#require method to check if it's loading .so/bundle file and copy it to the /tmp folder if so.

You can check the code here:
https://github.com/motor-admin/motor-admin/blob/master/config/boot.rb#L29

This monkey patch also solves the issue with slow app boot - #160

@omohokcoj Thanks a lot. It helped but seems I far away from getting this done.

Seems it's not gonna work for me. :( I'm getting now:
activesupport/lib/active_support/deprecation/proxy_wrappers.rb:172:in method_missing': private method warn' called for nil:NilClass (NoMethodError) - fixed by making warn method public in boot.rb :)
activesupport/lib/active_support/inflector/methods.rb:275:in `const_get': wrong constant name

@kritik https://github.com/motor-admin/motor-admin/blob/master/config/boot.rb#L29 - i had to warn you that the require method monkey patch is not reliable and probably works only for my application.

You can try to remove the monkey patch for .rb files and use it only for .so and .bundle files:
https://github.com/motor-admin/motor-admin/blob/master/config/boot.rb#L16 - remove .rb extension from here but keep so/bundle

This might help but will make the app boot time very slow - up to 30 seconds.

Thanks for your help. I have marked that you also cache rb files. :) Unfortunately removing rb file from caching didn't help me.

@ericbeland sure, feel free to reuse those monkey patches
