"SVN Change Sets" model does not always display date and author information

Description

In the Synchronize View:

• Incoming changes
• SVN Change Sets enabled

some change sets do not contain neither date nor author, but display "6955 (no date) [no author]".

Looking at the specific change set in more details:

• File 1: deleted (date and author available from the last version)
• File 2: added (here both date and author are available)

So I guess somehow the information from File 2 is not taken for the change set date and author tags.

What happens if only deleted files are in change set? Is it possible to get date and author information then?

h1. Steps to reproduce

• At revision 4241:
  ** directories @dir1/dir2@ and @dir1/dir3@
• Create @file-1.txt@
• Delete @file-1.txt@ outside Eclipse in another workspace
• Create @file-2.txt@ outside Eclipse in another workspace
• Commit both changes outside Eclipse in another workspace with comment "XXX"
• Synchronize in Eclipse
• Go to incoming changes
• Switch to SVN Changesets model

By Igor Burilo

This problem happens because of following reason:
In order to create change set name which contains revision, date and author change set collector traverses all resources which belong to particular change set and retrieves date and author info. But for deleted resources SVN doesn't return date and author info, so for example, if there's only one deleted resource in change set, then this change set will not have initialized date and author part in its name.

How we can resolve this problem: as there're cases in which date and author are not initialized we need to make additional query to SVN in order to retrieve them, e.g. we can retrieve this info by log operation. But as we'll touch server we'll probably need to somehow cache log entries as it's time intensive operation.
