[PATCH] Fix issue #1673 - svn merge reports File Not Found (single, unmodified,

From: Marcos Chaves <mchvs_at_hotmail.com>
Date: 2004-08-08 23:15:34 CEST

Hello.

I split the patch for this issue in two: the bug fix patch and the
regression test patch.

The first patch fixes issue #1673 by ignoring ENOENT (file not found)
when deleting temporary files that may not exist if they were
renamed. It is the second approach presented by Francois Beausoleil
when the issue was discussed.

The second patch is the regression test for this modification.

My suggestion on how to apply the patches is:

  1) Apply the regression test patch (the second one) and verify
     that the test actually fails.
  2) Apply the bug fix patch (the first one).
  3) Verify that now the new test case passes.

Marcos
