Phusion Passenger is software that deploys Ruby and Python web apps, by integrating into Apache and Nginx and turning them into a fully-featured application server. It is very fast, stable and robust and thus used by the likes of New York Times, AirBnB, Symantec, Pixar, etc. It comes with many features that makes your life easier and your application perform better.
Phusion Passenger is under constant maintenance and development. Version 4.0.3 is a bugfix release.
Phusion Passenger also has an Enterprise version which comes with a wide array of additional features. By buying Phusion Passenger Enterprise you will directly sponsor the development of the open source version.
- Better protection is now provided against application processes that are stuck and refuse to shut down cleanly. Since version 4.0.0, Phusion Passenger already forcefully shuts down all processes during web server shutdown. In addition to this, 4.0.3 now also forcefully shuts down processes that take more than 1 minute to shut down, even outside the context of web server shutdowns. This feature does not, however, protect against requests that take too long. Use PassengerMaxRequestTime (Apache) or passenger_max_request_time (Nginx) for that.
- Fixed a crash in the HelperAgent which results in frequent process restarts in some traffic patterns. Fixes issue #862.
- Fixed a problem that prevents processes from being spawned correctly if the user’s bashrc changes working directory. Fixes issue #851.
- passenger-status now also displays CPU usage.
- The installer now checks for checksums when automatically downloading PCRE and Nginx. Contributed by Joshua Lund.
- An error is now printed when trying to daemonize Phusion Passenger Standalone on Ruby implementations that don’t support forking. Contributed by Benjamin Fleischer.
- Although Phusion Passenger already supported JRuby, installing Phusion Passenger with JRuby was not possible. This has been fixed.
- Various other minor bug fixes.
Open source users can install the open source version of 4.0.3 with the following commands:
gem install passenger passenger-install-apache2-module passenger-install-nginx-module
