-# Tracing
-
- Stability: 1 - Experimental
-
-The tracing module is designed for instrumenting your Node application. It is
-not meant for general purpose use.
-
-***Be very careful with callbacks used in conjunction with this module***
-
-Many of these callbacks interact directly with asynchronous subsystems in a
-synchronous fashion. That is to say, you may be in a callback where a call to
-`console.log()` could result in an infinite recursive loop. Also of note, many
-of these callbacks are in hot execution code paths. That is to say your
-callbacks are executed quite often in the normal operation of Node, so be wary
-of doing CPU bound or synchronous workloads in these functions. Consider a ring
-buffer and a timer to defer processing.
-
-`require('tracing')` to use this module.
-
-## v8
-
-The `v8` property is an [EventEmitter][], it exposes events and interfaces
-specific to the version of `v8` built with node. These interfaces are subject
-to change by upstream and are therefore not covered under the stability index.
-
-### Event: 'gc'
-
-`function (before, after) { }`
-
-Emitted each time a GC run is completed.
-
-`before` and `after` are objects with the following properties:
-
-```
-{
- type: 'mark-sweep-compact',
- flags: 0,
- timestamp: 905535650119053,
- total_heap_size: 6295040,
- total_heap_size_executable: 4194304,
- total_physical_size: 6295040,
- used_heap_size: 2855416,
- heap_size_limit: 1535115264
-}
-```
-
-### getHeapStatistics()
-
-Returns an object with the following properties
-
-```
-{
- total_heap_size: 7326976,
- total_heap_size_executable: 4194304,
- total_physical_size: 7326976,
- used_heap_size: 3476208,
- heap_size_limit: 1535115264
-}
-```
-
-
-# Async Listeners
-
-The `AsyncListener` API is the JavaScript interface for the `AsyncWrap`
-class which allows developers to be notified about key events in the
-lifetime of an asynchronous event. Node performs a lot of asynchronous
-events internally, and significant use of this API may have a
-**significant performance impact** on your application.
-
-
-## tracing.createAsyncListener(callbacksObj[, userData])
-
-* `callbacksObj` {Object} Contains optional callbacks that will fire at
-specific times in the life cycle of the asynchronous event.
-* `userData` {Value} a value that will be passed to all callbacks.
-
-Returns a constructed `AsyncListener` object.
-
-To begin capturing asynchronous events pass either the `callbacksObj` or
-pass an existing `AsyncListener` instance to [`tracing.addAsyncListener()`][].
-The same `AsyncListener` instance can only be added once to the active
-queue, and subsequent attempts to add the instance will be ignored.
-
-To stop capturing pass the `AsyncListener` instance to
-[`tracing.removeAsyncListener()`][]. This does _not_ mean the
-`AsyncListener` previously added will stop triggering callbacks. Once
-attached to an asynchronous event it will persist with the lifetime of the
-asynchronous call stack.
-
-Explanation of function parameters:
-
-
-`callbacksObj`: An `Object` which may contain several optional fields:
-
-* `create(userData)`: A `Function` called when an asynchronous
-event is instantiated. If a `Value` is returned then it will be attached
-to the event and overwrite any value that had been passed to
-`tracing.createAsyncListener()`'s `userData` argument. If an initial
-`userData` was passed when created, then `create()` will
-receive that as a function argument.
-
-* `before(context, userData)`: A `Function` that is called immediately
-before the asynchronous callback is about to run. It will be passed both
-the `context` (i.e. `this`) of the calling function and the `userData`
-either returned from `create()` or passed during construction (if
-either occurred).
-
-* `after(context, userData)`: A `Function` called immediately after
-the asynchronous event's callback has run. Note this will not be called
-if the callback throws and the error is not handled.
-
-* `error(userData, error)`: A `Function` called if the event's
-callback threw. If this registered callback returns `true` then Node will
-assume the error has been properly handled and resume execution normally.
-When multiple `error()` callbacks have been registered only **one** of
-those callbacks needs to return `true` for `AsyncListener` to accept that
-the error has been handled, but all `error()` callbacks will always be run.
-
-`userData`: A `Value` (i.e. anything) that will be, by default,
-attached to all new event instances. This will be overwritten if a `Value`
-is returned by `create()`.
-
-Here is an example of overwriting the `userData`:
-
- tracing.createAsyncListener({
- create: function listener(value) {
- // value === true
- return false;
- }, {
- before: function before(context, value) {
- // value === false
- }
- }, true);
-
-**Note:** The [EventEmitter][], while used to emit status of an asynchronous
-event, is not itself asynchronous. So `create()` will not fire when
-an event is added, and `before()`/`after()` will not fire when emitted
-callbacks are called.
-
-
-## tracing.addAsyncListener(callbacksObj[, userData])
-## tracing.addAsyncListener(asyncListener)
-
-Returns a constructed `AsyncListener` object and immediately adds it to
-the listening queue to begin capturing asynchronous events.
-
-Function parameters can either be the same as
-[`tracing.createAsyncListener()`][], or a constructed `AsyncListener`
-object.
-
-Example usage for capturing errors:
-
- var fs = require('fs');
-
- var cntr = 0;
- var key = tracing.addAsyncListener({
- create: function onCreate() {
- return { uid: cntr++ };
- },
- before: function onBefore(context, storage) {
- // Write directly to stdout or we'll enter a recursive loop
- fs.writeSync(1, 'uid: ' + storage.uid + ' is about to run\n');
- },
- after: function onAfter(context, storage) {
- fs.writeSync(1, 'uid: ' + storage.uid + ' ran\n');
- },
- error: function onError(storage, err) {
- // Handle known errors
- if (err.message === 'everything is fine') {
- // Writing to stderr this time.
- fs.writeSync(2, 'handled error just threw:\n');
- fs.writeSync(2, err.stack + '\n');
- return true;
- }
- }
- });
-
- process.nextTick(function() {
- throw new Error('everything is fine');
- });
-
- // Output:
- // uid: 0 is about to run
- // handled error just threw:
- // Error: really, it's ok
- // at /tmp/test2.js:27:9
- // at process._tickCallback (node.js:583:11)
- // at Function.Module.runMain (module.js:492:11)
- // at startup (node.js:123:16)
- // at node.js:1012:3
-
-## tracing.removeAsyncListener(asyncListener)
-
-Removes the `AsyncListener` from the listening queue.
-
-Removing the `AsyncListener` from the active queue does _not_ mean the
-`asyncListener` callbacks will cease to fire on the events they've been
-registered. Subsequently, any asynchronous events fired during the
-execution of a callback will also have the same `asyncListener` callbacks
-attached for future execution. For example:
-
- var fs = require('fs');
-
- var key = tracing.createAsyncListener({
- create: function asyncListener() {
- // Write directly to stdout or we'll enter a recursive loop
- fs.writeSync(1, 'You summoned me?\n');
- }
- });
-
- // We want to begin capturing async events some time in the future.
- setTimeout(function() {
- tracing.addAsyncListener(key);
-
- // Perform a few additional async events.
- setTimeout(function() {
- setImmediate(function() {
- process.nextTick(function() { });
- });
- });
-
- // Removing the listener doesn't mean to stop capturing events that
- // have already been added.
- tracing.removeAsyncListener(key);
- }, 100);
-
- // Output:
- // You summoned me?
- // You summoned me?
- // You summoned me?
- // You summoned me?
-
-The fact that we logged 4 asynchronous events is an implementation detail
-of Node's [Timers][].
-
-To stop capturing from a specific asynchronous event stack
-`tracing.removeAsyncListener()` must be called from within the call
-stack itself. For example:
-
- var fs = require('fs');
-
- var key = tracing.createAsyncListener({
- create: function asyncListener() {
- // Write directly to stdout or we'll enter a recursive loop
- fs.writeSync(1, 'You summoned me?\n');
- }
- });
-
- // We want to begin capturing async events some time in the future.
- setTimeout(function() {
- tracing.addAsyncListener(key);
-
- // Perform a few additional async events.
- setImmediate(function() {
- // Stop capturing from this call stack.
- tracing.removeAsyncListener(key);
-
- process.nextTick(function() { });
- });
- }, 100);
-
- // Output:
- // You summoned me?
-
-The user must be explicit and always pass the `AsyncListener` they wish
-to remove. It is not possible to simply remove all listeners at once.
