Description EPP Error Reports CLA 2015-11-04 05:41:32 EST 
The generic UI contribution of the Viewers framework can cause UI freezes, as its it loads constraint specifications to decide whether they correspond to the current editor, regardless whether they have been loaded before, and this might result in loading multiple bundles.

The culprit here is the ValidationManager#loadConstraintSpecificationsFromExtensions() method. What needs to be done is similar to the actions required for bug 470392: make sure that the classes are not loaded until necessary; deciding whether the contribution needs to be shown should not require loading the patterns themselves.


The freeze was reported multiple times using the error reporter service. The original reports are as follows:

Comment 1 Abel Hegedus CLA 2015-11-04 07:27:03 EST 
Based on these three traces, the culprit is 
org.eclipse.incquery.runtime.internal.ExtensionBasedSurrogateQueryLoader.loadKnownSurrogateQueriesIntoRegistry(ExtensionBasedSurrogateQueryLoader.java:54)
    at org.eclipse.incquery.runtime.IncQueryRuntimePlugin.start(IncQueryRuntimePlugin.java:27)

Indeed. We should think about a way to handle these definitions without loading the incquery runtime...
Comment 3 Abel Hegedus CLA 2015-11-04 09:03:19 EST 
I can get around loading the incquery.runtime plugin when checking the Validation contributions, but it breaks the ValidationManager API as I would need to remove a method that I want to set as deprecated anyway (initializeValidationEngine(Notifier notifier, String editorId))

While this method is there, the class loader initializes the plugin while loading the IncQueryScope class before invoking ValidationManager.isConstraintSpecificationsRegisteredForEditorId(editorId) even though it is not used there.

Comment 5 Abel Hegedus CLA 2015-11-04 09:47:55 EST 
I think I managed to fix the issue without breaking any API, see Gerrit change.

What if we move the code not requiring to a base class of the existing ValidationManager? That way, we maintain compatibility, but still can use the features without starting IncQuery runtime.
Comment 8 Abel Hegedus CLA 2015-11-05 08:19:32 EST 
We have merged an internal refactor to avoid starting the incquery.runtime plugin before it is really necessary.

The first change only avoids loading incquery.runtime if there are no registered validation constraints at all. I have done the switch to the provider based approach now.

Added provider based handling of constraint specifications loaded from extensions to avoid starting incquery.runtime during enablement checking.
