             Summary: dump/load mergeinfo-mod difference with --deltas
                 Key: SVN-4728
                 URL: https://issues.apache.org/jira/browse/SVN-4728
             Project: Subversion
          Issue Type: Bug
          Components: libsvn_fs_fs
    Affects Versions: trunk
            Reporter: Philip Martin


When a revision is a property-only change to a node that has svn:mergeinfo then a dump/load of that revision produces different representations in new repository depending on whether --deltas is used when dumping.

The original repository:

svnadmin create repo
 svnmucc -mm -U [file://|file:///]`pwd`/repo mkdir A
 svnmucc -mm -U [file://|file:///]`pwd`/repo propset svn:mergeinfo /B:1 A
 svnmucc -mm -U [file://|file:///]`pwd`/repo propset p2 v2 A

Dump and load without --deltas

svnadmin dump repo | svnadmin load repo2
 svnadmin dump --deltas repo | svnadmin load repo3

Note the difference in the r3 revision files:

$ grep -a modify-dir repo[23]/db/revs/0/3

repo2/db/revs/0/3:0-1.0.t2-2 modify-dir false true true /A
 repo3/db/revs/0/3:0-1.0.t2-2 modify-dir false true false /A

The field that differs is mergeinfo-mod, introduced in 1.9. The problem doesn't occur in earlier versions.
