日志在生产中无法正常工作并延迟工作

问题描述

我遇到了一些奇怪的问题，即我的delay_jobs生产失败。最后，我将其范围缩小到记录器。如果我注释掉我的log函数调用，则一切正常。但是，如果我尝试登录，则会在delay_job处理程序中得到它：

  ---！ruby / struct：Delayed :: PerformableMethod 
对象：AR：User：1 
方法：：load_and_update_without_send_later 
 args：[] 
 
 |闭流
 /opt/ruby/lib/ruby/1.8/logger.rb:504：在`write'

我的记录器如下：
  @@ error_log_file = File.open（ ＃{RAILS_ROOT} /log/error.log，'a'）
 @@ error_log_file.sync = true 
 def log（msg）
 msg.each | line |

 @@ error_log_file.info（line）＃这是第35行，其中

如果我评论
 
 
 
这是一个延迟的工作问题，还是与我的日志目录有关？符号链接（由标准的capistrano部署设置）？
 
 
 
也没有将任何内容写入我的error.log文件，也没有任何内容写入delay_job.log。完全陷入困境...

I'm suffering some weird issue where my delayed_jobs are failing in production.  Finally I narrowed it down to the logger.  If I comment out my log function calls, everything works.  However if I try to log, I get this in the delayed_job handler:
 --- !ruby/struct:Delayed::PerformableMethod
object: AR:User:1
method: :load_and_update_without_send_later
args: []

 | closed stream
/opt/ruby/lib/ruby/1.8/logger.rb:504:in `write'
/opt/ruby/lib/ruby/1.8/logger.rb:504:in `write'
/opt/ruby/lib/ruby/1.8/monitor.rb:242:in `synchronize'
/opt/ruby/lib/ruby/1.8/logger.rb:496:in `write'
/opt/ruby/lib/ruby/1.8/logger.rb:326:in `add'

/home/rails/myapp.com/releases/20100203203031/app/models/gmail.rb:35:in `log'
My logger looks like this:
@@error_log_file = File.open("#{RAILS_ROOT}/log/error.log", 'a')
@@error_log_file.sync = true
def log(msg)
  msg.each do |line|
    line = "#{Time.now.strftime('%H:%M:%S')}  #{line}"
    @@error_log_file.info(line) # this is line 35 where it's failing
    puts line
  end
end
If I comment out the line "@@error_log_file.sync = true", it also works.
Is this a delayed job problem, or could it be related to my log directory being a symbolic link (as setup by a standard capistrano deploy)?
Also nothing is being written to my error.log file and nothing is being written to delayed_job.log.  Totally stumped...

Works for me perfectly!
