            Bug ID: 156618
           Summary: svn-apply: add option for ignoring changes to
                    ChangeLog files
    Classification: Unclassified
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Tools / Tests
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: dburkart at apple.com

It would be nice if svn-apply had an option to skip all changes to ChangeLog files, for use
when not planning to commit after application. The specific case I am thinking of that this
would help with is the following scenario:

- The user is using git-svn (not sure if this happens with pure SVN)
- There are two ChangeLog entries in a row with the same header
- The user neglected to `git-svn rebase` or `svn up` before generating the patch

In this case, git will generate a patch that looks something like this:

2016-04-14  John Doe  <johndoe at webkit.org>
+
+        Enhance interface foo with bar.
+
+        Reviewed By: NOBODY (OOPS).
+
+        This change does something
+
+2016-04-14  John Doe  <johndoe at webkit.org>

         Some other change that happens to be by John Doe.


The behavior of svn-apply, which is to attempt to patch the ChangeLog with `patch --fuzz=3`,
will not be sufficient, since a fuzz value of 3 will not work with this patch if HEAD has a 
completely different ChangeLog entry at the top.
