--------------------------------

             Summary: Merge: the resulting mergeinfo is non-deterministic
                 Key: SVN-4862
                 URL: https://issues.apache.org/jira/browse/SVN-4862
             Project: Subversion
          Issue Type: Bug
            Reporter: Julian Foad


In a particular merge scenario (e.g. merge_tests.py 143, see SVN-4859), the merge result is non-deterministic: it produces slightly different results on different runs, at random.

The variations in output are (in that test):
{code:none}
--- Recording mergeinfo for merge of r3 through r7 into '.../A':
 U   .../A
--- Recording mergeinfo for merge of r3 through r7 into '.../A/D/G':
 G   .../A/D/G
--- Recording mergeinfo for merge of r3 through r7 into '.../A/D/G2':
 G   .../A/D/G2
 G   .../A/D

svn pg -R svn:mergeinfo A/
A      - /branch_A:3-7
A/D    - /branch_A/D:5-7     /branch_B/C:1*
A/D/G  - /branch_A/D/G:5-7   /branch_B/C/G:1*
A/D/G2 - /branch_A/D/G2:5-7  /branch_B/C/G2:1*
{code}
vs.
{code:none}
--- Recording mergeinfo for merge of r3 through r7 into '.../A':
 U   .../A
--- Recording mergeinfo for merge of r3 through r7 into '.../A/D/G':
 U   .../A/D/G
--- Recording mergeinfo for merge of r3 through r7 into '.../A/D/G2':
 U   .../A/D/G2
 G   .../A/D

svn pg -R svn:mergeinfo A/
A      - /branch_A:3-7
A/D    - /branch_A/D:5-7     /branch_B/C:1*
A/D/G  - /branch_A/D/G:5-7   /branch_B/C/G:1*
A/D/G2 - /branch_A/D/G2:6-7  /branch_B/C/G2:1*

or

A      - /branch_A:3-7
A/D    - /branch_A/D:5-7     /branch_B/C:1*
A/D/G  - /branch_A/D/G:6-7   /branch_B/C/G:1*
A/D/G2 - /branch_A/D/G2:6-7  /branch_B/C/G2:1*
{code}
