Bug 172355

Description John O'Shea 2007-01-31 13:58:24 EST

Build ID: M20060921-0945

Steps To Reproduce:
1. Import attached plugin project.
2. Run com.capeclear.efs.test.ResourceExistsTest test suite (as Junit Plugin Tests)
3. Observe that testStupidlyLongResourceName fails.


More information:
The problem appears to be in the EFS LocalFile FileStore implementation.  It appears that for resources with external form paths that exceed 255 characters the local IFileStore implementation creates a IFileInfo object that does not have the EXISTS attribute set correctly.

Setting a breakpoint at 
Thread [main] (Suspended (breakpoint at line 595 in org.eclipse.core.internal.localstore.FileSystemResourceManager))	
	org.eclipse.core.internal.localstore.FileSystemResourceManager.read(org.eclipse.core.resources.IFile, boolean, org.eclipse.core.runtime.IProgressMonitor) line: 595	
	org.eclipse.core.internal.resources.File.getContents(boolean) line: 290	
	org.eclipse.core.internal.resources.File.getContents() line: 279	
	com.capeclear.efs.test.ResourceExistsTest.tryCreateAndReadNewResourceInFolder(org.eclipse.core.resources.IFolder) line: 69	
	com.capeclear.efs.test.ResourceExistsTest.testReasonablyLongResourceName() line: 36

will allow you to observe that fileInfo.exists() returns false for the resource whose contents are being retrieved by this test.

I'm not sure if you are going to be able to resolve this as I think the 255 limit is imposed by Windows (NTFS)?  

Regardless, the error message currently returned by is very misleading.  The ResourceException subsequently thrown states that the project does not exist (when it does).  This is a side effect of exists() incorrectly returning false.
