@btesser I am trying to reproduce this with a minimal example and was unable With a comment on the line to write to the console, then it looks like there is no leak. If this is commented, then Chrome leaks several $scope as the arguments (in one way or another) point to the scope. Even in this case, if you clear the console, then the scopes are collected by the GC. Can you please create a small example that shows this leak or let us know what is wrong with the example? |
|
me neither. one important note: don't log into console while looking for leaks. the console will retain references to all the objects logged, which makes them appear as if they were leaking. Can you provide a better example either via plunker or fiddle that we could work with? |
|
this is the plunk I was working off of: http://plnkr.co/edit/QsowAsia3ecRRnKC4mwI?p=preview if you run the example in fullscreen mode and use timeline or profiler after hitting the start button, I don't see any leak. All references always get collected by GC. |
|
Try this version. Modified it to be an element and have a second bound value http://plnkr.co/edit/TW2TjC8JkxlDyQRCLcRg?p=preview Click leak, then click home. Run GC. Leak scope still in heap |
|
@btesser can you provide a screenshot, showing the memory leak for you? |
|
Ok, I think I am able to reproduce this. A fix should be easy |

For functions that have a '&' binding on the scope, change the function from an inline definition to an external definition so the function closure has no access to the parent scope. Closes angular#6794

I still can't repro this using @btesser's link. here is what I see: I let this run over a "long" period of time, and it clearly shows that there is no leak. Sometimes it takes a few seconds for the GC to kick in and collect all the stuff, but it's never the case that objects just keep on accumulating without GC. |
|
Since I can't reproduce the problem when running the test app for long periods of time and the fix provided doesn't actually release any references that should not be retained, I don't think that we are actually dealing with a leak here. Hunting down memory leaks is a tricky business and in the past I was several times distracted by non-leaks that masqueraded the actual problem. So I'm not saying that you don't have a leak in your app, I just think that this reduction is an incorrect reduction of your issue and the patch offered doesn't do anything to solve the actual problem. If you have any information that could help me reproduce the issue, I'm happy to keep on investigating, but as it stands right now I don't have anything to base my search on. Just for the record I'm adding links to two known V8 and Chrome issues that could be related to what you might be observing in your app: |

ok, after many failed attempts I was able to create a test case that shows that there is a leak. The leak is coming from V8 as originally suspected. I'm yet to confirm that '&' plays any role here. Here is my reduction: http://plnkr.co/edit/uaUMreckGASCTOsuNYlo?p=preview For the record here is the retaining tree of the leaked scope which clearly shows that the references that are preventing GC are coming from V8: |

as I suspected, the issue that I can reproduce has nothing to do with the use of isolate scope I can repro the same thing with this example that doesn't use such bindings: http://plnkr.co/edit/FrSw6SCEVODk02Ljo8se?p=preview |

Due to a known V8 memory leak[1] we need to perform extra cleanup to make it easier for GC to collect this scope object. The theory is that the V8 leaks are due to inline caches which are caches built on the fly to speed up property access for javascript objects. By cleaning the scope object and removing all properties, we clean up ICs as well and so no leaks occur. I was able to manually verify that this fixes the problem for the following example app: http://plnkr.co/edit/FrSw6SCEVODk02Ljo8se?p=preview Given the nature of the problem I'm not 100% sure that this will work around the V8 problem in scenarios common for Angular apps, but I guess it's better than nothing.

@IgorMinar Will do |
|
@IgorMinar I would not suggest to do that because lot of applications will be incompatible. @btesser Take a look this: |
|
@igorzg: what application will depend on scope properties after the scope is destroyed? |
|
@caitp Everything what have async reference to scope. Example if we have an dialog with promise resolution on close, close will also destroy the scope. After you have promise resolved and if your promise relay on some data of scope with this patch you will not able to see that data. With current solution you cleanup references to scope data in promise afterwards. |
|
You could always resolve a clone of the object in scope that you're referencing, though, and that's probably easier for people to remember for the specific cases where they need this, than it is to manually cleanup every scope in the app... |
|
@caitp I agree with you. I'm just saying that patch will cause bugs, and you have to provide a notice in changelog that may be a reason. |

First of all , I like to say we also encountered the leak mentioned here in our application. After updating, to avoid getting errors, we had to check "$scope.$$destroyed" on all resolve callbacks. Problem is when our script makes a call to server, before server gets back to the client , if user clicks away and somehow close the scope initializing the call to server, we get an error inside the callback function trying to access the destroyed scope. |
|
@lgalfaso What I mentioned above is a bit more than just listeners. I'm going to explain what we had by a simple example: $scope.data = {}; // here an error will be thrown because $scope.data is null. If somehow $scope has got destroyed before this promise gets resolved. |
|
I'm reopening this issue because of two issues:
I do believe that the (again: keep in mind that the real issue we are debugging here is the V8 bug referenced earlier that I can't fix from JS, I'm just looking for a javascript code that would work around this bug and not cause V8 to leak. The proper fix needs to be done in V8 and the V8 guys are working on it, but it's going to take some time) |
|
Spent a couple of hours on this and here's what I found so far:
case '&': {

The reason why the leak shows up only sometimes is because it's coming from

Due to a known V8 memory leak[1] we need to perform extra cleanup to make it easier for GC to collect this scope object. V8 leaks are due to strong references from optimized code (fixed in M34) and inline caches (fix in works). Inline caches are caches that the virtual machine builds on the fly to speed up property access for javascript objects. These caches contain strong references to objects so under certain conditions this can create a leak. The reason why these leaks are extra bad for Scope instances is that scopes hold on to ton of stuff, so when a single scope leaks, it makes a ton of other stuff leak. This change removes references to objects that might be holding other big objects. This means that even if the destroyed scope leaks, the child scopes should not leak because we are not explicitly holding onto them. Additionally in theory we should also help make the current scope eligible for GC by changing properties of the current Scope object. I was able to manually verify that this fixes the problem for the following example app: http://plnkr.co/edit/FrSw6SCEVODk02Ljo8se Given the nature of the problem I'm not 100% sure that this will work around the V8 problem in scenarios common for Angular apps, but I guess it's better than nothing. This is a second attempt to enhance the cleanup, the first one failed and was reverted because it was too aggressive and caused problems for existing apps. See: angular#6897 [1] V8 bug: https://code.google.com/p/v8/issues/detail?id=2073 Closes angular#6794 Closes angular#6856

@IgorMinar Was just working with another team that was experiencing an identical issue. We were able to isolate the problem down to a single, simplified example and tested in Chrome Canary, which should include the fix to V8 (according to V8:2073#35), but I can still produce memory leaks. Do you have any insight from the V8 team about this? |

+ * {@link angular.module module} name to load.
+ *
+ * @description
+ *
+ * Use this directive to **auto-bootstrap** an AngularJS application. The `ngApp` directive
+ * designates the **root element** of the application and is typically placed near the root element
+ * of the page - e.g. on the `<body>` or `<html>` tags.
+ *
+ * Only one AngularJS application can be auto-bootstrapped per HTML document. The first `ngApp`
+ * found in the document will be used to define the root element to auto-bootstrap as an
+ * application. To run multiple applications in an HTML document you must manually bootstrap them using
+ * {@link angular.bootstrap} instead. AngularJS applications cannot be nested within each other.
+ *
+ * You can specify an **AngularJS module** to be used as the root module for the application. This
+ * module will be loaded into the {@link auto.$injector} when the application is bootstrapped and
+ * should contain the application code needed or have dependencies on other modules that will
+ * contain the code. See {@link angular.module} for more information.
+ *
+ * In the example below if the `ngApp` directive were not placed on the `html` element then the
+ * document would not be compiled, the `AppController` would not be instantiated and the `{{ a+b }}`
+ * would not be resolved to `3`.
+ *
+ * `ngApp` is the easiest, and most common, way to bootstrap an application.
+ *
+ <example module="ngAppDemo">
+ <file name="index.html">
+ <div ng-controller="ngAppDemoController">
+ I can add: {{a}} + {{b}} = {{ a+b }}
+ </div>
+ </file>

+ angular.module('ngAppDemo', []).controller('ngAppDemoController', function($scope) {

+ * This object provides a utility for producing rich Error messages within
+ * Angular. It can be called as follows:
+ *
+ * var exampleMinErr = minErr('example');
+ * throw exampleMinErr('one', 'This {0} is {1}', foo, bar);
+ *
+ * The above creates an instance of minErr in the example namespace. The
+ * resulting error will have a namespaced error code of example.one. The
+ * resulting error will replace {0} with the value of foo, and {1} with the
+ * value of bar. The object is not restricted in the number of arguments it can
+ * take.
+ *
+ * If fewer arguments are specified than necessary for interpolation, the extra
+ * interpolation markers will be preserved in the final string.
+ *
+ * Since data will be parsed statically during a build step, some restrictions
+ * are applied with respect to how minErr instances are created and called.
+ * Instances should have names of the form namespaceMinErr for a minErr created
+ * using minErr('namespace') . Error codes, namespaces and template strings
+ * should all be static strings, not variables or general expressions.
+ *
+ * @param {string} module The namespace to use for the new minErr instance.
+ * @param {function} ErrorConstructor Custom error constructor to be instantiated when returning

+ * @param {angular.Module} ngApp an optional application
+ * {@link angular.module module} name to load.
+ * @param {boolean=} ngStrictDi if this attribute is present on the app element, the injector will be
+ * created in "strict-di" mode. This means that the application will fail to invoke functions which
+ * do not use explicit function annotation (and are thus unsuitable for minification), as described
+ * in {@link guide/di the Dependency Injection guide}, and useful debugging info will assist in
+ * tracking down the root of these bugs.
+ *
+ * @description
+ *
+ * Use this directive to **auto-bootstrap** an AngularJS application. The `ngApp` directive
+ * designates the **root element** of the application and is typically placed near the root element
+ * of the page - e.g. on the `<body>` or `<html>` tags.
+ *
+ * Only one AngularJS application can be auto-bootstrapped per HTML document. The first `ngApp`
+ * found in the document will be used to define the root element to auto-bootstrap as an
+ * application. To run multiple applications in an HTML document you must manually bootstrap them using
+ * {@link angular.bootstrap} instead. AngularJS applications cannot be nested within each other.
+ *
+ * You can specify an **AngularJS module** to be used as the root module for the application. This
+ * module will be loaded into the {@link auto.$injector} when the application is bootstrapped and
+ * should contain the application code needed or have dependencies on other modules that will
+ * contain the code. See {@link angular.module} for more information.
+ *
+ * In the example below if the `ngApp` directive were not placed on the `html` element then the
+ * document would not be compiled, the `AppController` would not be instantiated and the `{{ a+b }}`
+ * would not be resolved to `3`.
+ *
+ * `ngApp` is the easiest, and most common, way to bootstrap an application.
+ *
+ <example module="ngAppDemo">
+ <file name="index.html">
+ <div ng-controller="ngAppDemoController">
+ I can add: {{a}} + {{b}} = {{ a+b }}

+ <div ng-controller="GoodController1">

When a directive is written using '&' reverse one way binding there is a major memory leak. Once it is entered in the DOM, the Scope of the directive, it's parent, and detached DOM elements are NEVER garbage collected. This is even after routing to another page and back. The $destroy event does get called, but any cleanup done does nothing to fix the leak.
Testing method:
We created an extremely simple directive:
We also created a simple router that switched between a plain text page and one with the directive.
Start on blank page, click link for page with directive, click link for blank page.
In chrome timeline force garbage collection.
Take heap snapshot. Despite being entirely gone from the page and no external references, directive is not GC'ed and because it contains a reference to it's parent, the parent is not collected either.
We then removed just the 1 way binding attribute.
The leak was gone.
Please let me know if you have any questions.
