Enabling Quick Diff crashes editors #8

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
Google Chrome version: 4.0.201.1
SDK + Eclipse Debugger version(s): 0.1.0.200907271854
OS + version: Win XP SP3

What steps will reproduce the problem?
1. Install subclipse
2. Have open projects associated with subversion repositories
3. Enable Quick Diff, using "pristine svn copy" as reference.

What is the expected result?
Javascript debugging works as expected

What happens instead?
Double clicking on a Google Chrome javascript file results in an error.
Switching perspectives results in screen display corruption with panels not 
updating.

Please provide any additional information below. If possible, attach a
(reduced) test-case.

(Earlier uncaptured error message was full of subversion classes. I've 
since upgraded to latest version of subversion, and the symptoms remained, 
but the stack trace changed)

Problems occurred when invoking code from plug-in: "org.eclipse.jface".

GoogleCodeExporter commented 8 years ago 
Hey,

You seem to be hitting a Subclipse problem. Subclipse always relies on 
projects/files 
located on a local filesystem, even for non-shared projects (e.g. it happens at 
org.tigris.subversion.subclipse.ui.SVNPristineCopyQuickDiffProvider.isEnabled(SV
NPris
tineCopyQuickDiffProvider.java:174)) and fails in various ways if the resource 
is 
located on a non-local EFS (i.e. identified only by a URL.)

If you look into your Eclipse Error Log, you will see an NPE thrown at
org.tigris.subversion.subclipse.core.status.RecursiveStatusUpdateStrategy:62
preceding the one you quoted in your report. The stacktrace contains
org.eclipse.ui.internal.texteditor.LineNumberColumn.initialize(LineNumberColumn.
java:
248). Above all, this exception prevents the LineNumberRulerColumn fCanvas 
field 
initialization which, in turn, results in the exception quoted.
