如何防止 Phusion 乘客覆盖 Rails 日志？

Question

我正在使用 nginx 测试乘客，在我的 log/development.log 文件中，看起来每个 SQL 请求都是由乘客触发的：

Decidim::Organization Load (0.3ms)  SELECT  "decidim_organizations".* FROM "decidim_organizations" WHERE "decidim_organizations"."host" = $1 LIMIT $2  [["host", "decidim.domain.tld"], ["LIMIT", 1]]
↳ /usr/lib/ruby/vendor_ruby/phusion_passenger/rack/thread_handler_extension.rb:107

虽然它看起来像预期的行为，但有没有办法将应用程序中的 file:line 添加到堆栈跟踪中？

我想要类似的东西：

Decidim::Organization Load (0.3ms)  SELECT  "decidim_organizations".* FROM "decidim_organizations" WHERE "decidim_organizations"."host" = $1 LIMIT $2  [["host", "decidim.domain.tld"], ["LIMIT", 1]]
↳ /home/user/ror_app/app/models/something.rb:42

添加 config.log_level = :debug 并重新启动服务器没有帮助。

Answer 1

你可以add_silencer（忽略）那些包含“phusion_passenger”（或更好：“passenger”）的行到BacktraceCleaner

# config/initializers/backtrace_silencer.rb
Rails.backtrace_cleaner.add_silencer { |line| /phusion_passenger/.match?(line) }

更新

基本上当您将那些passenger 行静音时，它应该显示您的应用程序日志，例如，我假设日志行如下

Decidim::Organization Load (0.3ms)  SELECT ...
↳ /usr/lib/ruby/vendor_ruby/phusion_passenger/rack/thread_handler_extension.rb:107
↳ another phusion_passenger
↳ /home/user/ror_app/app/models/something.rb:42
...

如果您对 phusion_passenger 行静音，则日志应显示 /home/user/ror_app/app/models/something

看看the log_subscriber code on Rails

如果中间还有许多其他行，为确保日志将显示应用程序的第一行代码，您可以覆盖上面的 log_subscriber 代码以忽略行，直到到达应用程序中的代码行.

# your_app/lib/active_record/log_subscriber.rb 
module ActiveRecord
  class LogSubscriber
    def extract_query_source_location(locations)
      # old code
      # backtrace_cleaner.clean(caller.lazy).first
   
      # new code: to make sure that you log the line of code in your app, 
      # you could replace the regex `/app/` by `/app\/model.../` or
      # whatever you want to reach the code you want to show in logs
      locations.lazy.filter { |line| /app/.match?(line) }.first # first(3)
    end
  end
end 

# config/initializers/ext_core.rb
require File.join(Rails.root, "lib", "active_record", "log_subcriber.rb") 

更新

我认为active-record-query-trace 可以帮助你。
