Changelog - 2010¶

0.12.0 / 2010-12-22¶

Add support for logging configuration using a ini file. It uses the standard Python logging’s module Configuration file format and allows anyone to use his custom file handler
Add IPV6 support
Add multidomain application example
Improve gunicorn_django command when importing settings module using DJANGO_SETTINGS_MODULE environment variable
Send appropriate error status on http parsing
Fix pidfile, set permissions so other user can read it and use it.
Fix temporary file leaking
Fix setpgrp issue, can now be launched via ubuntu upstart
Set the number of workers to zero on WINCH

Improve gevent’s workers. Add “egg:gunicorn#gevent_wsgi” worker using gevent.wsgi and “egg:gunicorn#gevent_pywsgi” worker using gevent.pywsgi . “egg:gunicorn#gevent” using our own HTTP parser is still here and is recommended for normal uses. Use the “gevent.wsgi” parser if you need really fast connections and don’t need streaming, keepalive or ssl.
Add pre/post request hooks
Exit more quietly
Fix gevent dns issue

New HTTP parser.
New HUP behaviour. Re-reads the configuration and then reloads all worker processes without changing the master process id. Helpful for code reloading and monitoring applications like supervisord and runit.
Added a preload configuration parameter. By default, application code is now loaded after a worker forks. This couple with the new HUP handling can be used for dev servers to do hot code reloading. Using the preload flag can help a bit in small memory VM’s.
Allow people to pass command line arguments to WSGI applications. See: examples/alt_spec.py
Added an example gevent reloader configuration: examples/example_gevent_reloader.py.
New gevent worker “egg:gunicorn#gevent2”, working with gevent.wsgi.
Internal refactoring and various bug fixes.
New documentation website.

Added when_ready hook. Called just after the server is started
Added preload setting. Load application code before the worker processes are forked.
Refactored Config
Fix pidfile
Fix QUIT/HUP in async workers
Fix reexec
Documentation improvements

Refactored Worker management for better async support. Now use the -k option to set the type of request processing to use
Added support for Tornado

Added support for chunked response.
Added proc_name option to the config file.
Improved the HTTP parser. It now uses buffers instead of strings to store temporary data.
Improved performance when sending responses.
Workers are now murdered by age (the oldest is killed first).

Added setproctitle support
Change privilege switch behavior. We now work like NGINX, master keeps the permissions, new uid/gid permissions are only set for workers.
