Patch #40802
closedSupport builder 3.3.0
Description
- Use BasicObject instead of BlankSlate for better compatibility with modern rubies. https://github.com/rails/builder/pull/15
unfortunately, this change breaks Redmine's API. LoadError: cannot load such file -- blankslate
the following patch removes that dependency in favor of BasicObject

Hello,
This problem is on 5.1-stable branche too
Thanks.
Updated by Go MAEDA 6 months ago
In the 5.0-stable branch, the test hangs if the patch is applied.
It can be reproduced by running ruby test/integration/api_test/memberships_test.rb
. In the test/log, SystemStackError was recorded.

For 5.1-stable and 5.0-stable, is it better to pin the version of builder to 3.2 than merge the patch?

Hello
In this patch the line "require 'blankslate'" can be deleted

@go_maeda the BasicObject doesn't know the method block_given? see https://ruby-doc.org/core-2.7.1/BasicObject.html so it falls under method_missing, causing an infinite loop...
this can be fixed by replacing it with "::Kernel.block_given?" or a simple "block"

Thank you for debugging the issue, the block_given?
was replaced with block
in r22027 but the 5.0-stable branch still uses it. This is the reason why the infinite loop happens in the 5.0-stable.
I have merged the fix to the stable branches.

I don't know how, but Redmine 4.2 seems impacted by this change. All our automated tests under Redmine 4 are now failing with this error message:
Run bundle exec rake db:create db:migrate
rake aborted!
