Merging binary files with ancestry

Hi All,

I submitted this post to the user forum on Friday 5/6/2009 but can't
find it :(

I have searched svn mailing list and goggled for an answer all day. I
will be grateful to anyone who can answer my question and put me out of
my misery as a logical explanation is eluding me and driving me insane.

Any help in this is greatly appreciated.

I came across an interesting issue while performing a merge on binary
files with and without using ancestry.
I am currently using svn 1.4.6

Step 0. Create a branch (MergeTest2) from trunk (note : trunk should
contain a binary file) (r29) Step 1. modify a binary file in trunk. (ie
copy another binary file on top of an existing file) and commit it (r30)
Step 2. merge trunk into branch and commit http://host/svn/sgs/trunk
r29:30 (r31)
Step 3. merge branch into trunk. http://host/svn/sgs/trunk
http://host/svn/sgs/branch/MergeTest2

Step 3 will display that the binary file was ** Updated **. But there is
** NO ** change in the Working Copy.

If you perform Step 3 with --ignore-ancestry then there is ** nothing **
on the display and no change in the Working Copy either. (what I would
expect).

My question is why would the --ignore-ancestry flag cause a difference
in merge display when there is ** NO change ** in the ancestry to start
with.

svn log the binary file in branch "MergeTest2" shows the following Note
: r25 & r27 are from trunk ** before ** creating the MergeTest2 branch.
This proves that svn is maintaining the ancestry relationship.
