Mainly small fixes, improvements, and workarounds for fork() issues with pseudo-random number generators shipped with Ruby (Kernel#rand, OpenSSL::Random (used by SecureRandom and also by Rails).
If there are any other fixes/improvements that could be useful let us know. I think this is nearing the end of the line for the 3.x series which will then go into maintenance mode. I'm looking at 4.x being the crazy series that allows us to run thousands of worker _processes_ and scale to mythical 4096 core systems :) The PRNG issues are documented in depth here (and links to Ruby Redmine): http://bogomips.org/unicorn.git/commit?id=1107ede7 http://bogomips.org/unicorn.git/commit?id=b3241621 If you're too lazy to upgrade, you can just do this in your after_fork hooks: after_fork do |server,worker| tmp = srand OpenSSL::Random.seed(tmp.to_s) if defined?(OpenSSL::Random) end There are also small log reopening (SIGUSR1) improvements: * relative paths may also be reopened, there's a small chance this will break with a handful of setups, but unlikely. This should make configuration easier especially since the "working_directory" configurator directive exists. Brought up by Matthew Kocher: http://thread.gmane.org/gmane.comp.lang.ruby.unicorn.general/900 * workers will just die (and restart) if log reopening fails for any reason (including user error). This is to workaround the issue reported by Emmanuel Gomez: http://thread.gmane.org/gmane.comp.lang.ruby.unicorn.general/906 -- Eric Wong _______________________________________________ Unicorn mailing list - [email protected] http://rubyforge.org/mailman/listinfo/mongrel-unicorn Do not quote signatures (like this one) or top post when replying
