Update on issue-2897 branch(non-reflective file changes getting merged!!!)

From: Kamesh Jayachandran <kamesh_at_collab.net>
Date: 2007-12-14 13:30:17 CET

Hi All,

Tasks are tracked via
http://svn.collab.net/repos/svn/branches/issue-2897/TODO-issue-2897.branch

Now I could extract the *non-reflected* change and apply that alone from
a reflective merge. See the attached patch.

The attached patch is still work in progress, most of the change is
getting the 'reflected_ranges' for a 'reflecive_range'
and make it available at the right place. *Sorry* I did not attach the
log message as I used to write one once completing the work.

For those curious about the extraction logic have a look at
'reflective_merge_file_changed' and the functions it calls.

Logic is very simple than originally thought,
Suppose if r6 is a reflective change of r3-5 from /trunk/test.c to
/fb/test.c + one adhoc change.
When we merge r6 from /fb to /trunk wc, this patch calls
'reflective_merge_file_changed'
with following arguments
older=/fb/test.c@5 (i.e prior to synch up or reflection)
yours=/fb/test.c@6 (i.e after synch up or reflection)
mine=WC/trunk/test.c

Just apply r3-5 from /trunk/test.c to 'older' and call our regular
'merge_file_changed', it will take care of the rest.

We have the 'merge_non_reflective_text_change' testcase, which passes
with this fix.

What is pending,
I need to implement other call backs and the testcase.
* reflective_merge_file_added,
* reflective_merge_file_deleted,
* reflective_merge_dir_added,
* reflective_merge_dir_deleted,
* reflective_merge_props_changed
* issues raised by David Glasser which is tracked in TODO-issue-2897.branch.
* More self review.

Thanks,

With regards
Kamesh Jayachandran
