Re: [mat-dev] Proposal: MAT Warning System

[Kevin Grigorenko <kevin.grigorenko@xxxxxxxxxx>]

Hey Andrew,

One idea is to auto-generate a "Memory Analyzer Loaded Dumps" project and add resources to it any time a dump is opened. We'd probably want to "clear" this project on startup so that the set of resources doesn't grow infinitely or have to be manually managed.

Here is an example of how a problem view might look. 



I modified MultiPaneEditor to implement IGotoMarker, added some dummy problem markers when an IFileEditorInput was received on opening a file from the project explorer, and added a  public void gotoMarker(IMarker arg0) method which when given a location would bring an existing list_objects page for the object to the top. 

I then ran MAT inside Eclipse, then created a project in the project explorer for the dump file, then opened the dump file. 

This was just a quick example to try out the idea - the gotoMarker also needs to run a  list_objects command if one does not already exist. 

The problem marker creation would need to be integrated into the new MAT warning framework. Also problem markers only seem to work with resources, so I'm not sure how to make a resource for a dump which is not in a workspace. Perhaps the dump would need to be linked into a project, or the index files linked into the project. When there are multiple snapshots in a dump [1 ] how could we show this in the project explorer? Could the project explorer expand from dump to snapshot[s] to classloaders/classes/objects?
