* Only use CLOCK_PROCESS_CPUTIME_ID if it's definedBart de Water2018-07-291-2/+8
| | | | It's not defined on JRuby and unlike monotonic time, concurrent-ruby doesn't have an cross-platform abstraction for this.
* Always subscribe to event objects via `AS::Notifications.subscribe`Aaron Patterson2018-07-261-0/+2
| | | | | | | We don't need to have a special subscribe method for objects. The regular `subscribe` method is more expensive than a specialized method, but `subscribe` should not be called frequently. If that turns out to be a hotspot, we can introduce a specialized method. :)
* Subscribe to event objects via `subscribe_event`Aaron Patterson2018-07-261-1/+1
| | | | | | Fanout notifier can send event objects to subscribers now. Also moved `end` lower in the `finish!` method to guarantee that CPU time is shorter than real time.

* Add cpu_time, idle_time, and allocations to EventEileen Uchitelle2018-07-261-0/+47
| | | | | | | | | | | | | | * Use process clock instead of Time.now This fixes any issues with the system clock changing and also eliminates 2 object allocations per event. * Add start! and finish! methods to the event object so we can record more information * Adds cpu time, idle time, and allocation count for a particular event.

* applies new string literal convention in activesupport/libXavier Noria2016-08-061-1/+1
| | | | | The current code base is not uniform. After some discussion, we have chosen to go with double quotes by default.
* Adds exception object to instrumenter's payloadRyan T. Hosford2015-12-311-0/+1
| | | | | | | - Adds new key/value pair to payload when an exception is raised e.g. `:exception_object=> #<RuntimeError: FAIL>` - Updates relevant test - Adds CHANGELOG entry
* Subscribing to notifications while inside the said instrumented section.thedarkone2015-11-281-2/+7
| | | | | | | | | | | | | The issue is that on the exit from Instrumenter#instrument section, an Evented listener will run into an error because its thread local (Thread.current[:_timestack]) has not been set up by the #start method (this obviously happens because the Evented listeners didn't exist at the time, since no subscribtion to that section was made yet). Note: support for subscribing to instrumented sections, while being inside those instrumented sections, might be removed in the future. Maybe fixes #21873.
* Replace `#=>` with `# =>` [ci skip]claudiob2014-12-171-1/+1
| | | | | | | | @rafaelfranca suggested in f7c7bcd9 that code examples should display the result after `# =>` and not after `#=>`. This commit replaces *all* the occurrences of `#=>` in the code documentation (mostly added by me :sob:) with the suggested `# =>`.
