uWSGI v2.0.5.1

This release is important to me (and my company) as it officially introduces a few features we developed for our needs and then contributed to uWSGI.

Special congratulations to my co-worker @btall for his first contribution and for those nice features to the metrics subsystem with many thanks as usual to @unbit for reviewing and merging them so quickly.

new features

  • graceful reload of mule processes (Credits: Paul Egan) : SIGHUP is now sent to mules instead of directly killing them, by default you have 60 seconds to react before a SIGKILL
  • –metrics-no-cores, –stats-no-cores, –stats-no-metrics : don't calculate and process all those core related metrics (gevent anyone ?)
  • reset_after_push for metrics (Credits: Babacar Tall) : this metric attribute ensures that the metric value is reset to 0 or its hardcoded initial_value every time the metric is pushed to some external system (like carbon, or statsd)
  • new metric_set_max and metric_set_min helpers (Credits: Babacar Tall) : can be used to avoid having to call ``metric_get`` when you need a metric to be set at a maximal or minimal value. Another simple use case is to use the ``avg`` collector to calculate an average between some *max* and *min* set metrics. Available in C and python.
