BufferedLogger threading issues
Reported by Brian Durand | April 5th, 2011 @ 03:06 AM
There are a couple of threading issues with ActiveSupport::BufferedLogger.
- If a thread is spawned and logs messages but does not flush the log, the messages will never be written and will remain in the buffer forever.
threads = []
urls.each do |url
threads << Thread.new do
logger.info("fetching #{url}")
fetch(url)
logger.info("#{url} retrieved")
end end
threads.each{|t| t.join}
- Silencing a logger for a block in one thread will silence it will silence it for all other threads as well. This means in a multi-threaded Rails application, log messages can be lost.
