Hi Mark,
I spent some time looking at this problem this morning. I'm not quite
sure what is going wrong yet and have to finish up some other TODOs
before continuing, but this script I'm using to reproduce your problem
with the greek tree might be of use to anyone who looks at it:
[[[
rem set URL to point to a vanilla greek repos
set
URL=file:///C:/SVN/src-trunk/Release/subversion/tests/cmdline/svn-test-w
ork/repositories/merge_tests-1
rem checkout WC
svn co %URL% merge_tests-1
rem r2 make a branch
svn copy %URL%/A merge_tests-1\A_COPY
svn ci -m "" merge_tests-1
rem r3 make a text mod on the branch
echo new content >> merge_tests-1\A_COPY\mu
svn ci -m "" merge_tests-1
rem r4 make a second branch
svn copy %URL%/A merge_tests-1\A_COPY_2
svn ci -m "" merge_tests-1
rem r5 make a text mod on the second branch
echo new content >> merge_tests-1\A_COPY_2\B\lambda
svn ci -m "" merge_tests-1
svn up merge_tests-1
rem r6 merge from first branch to second branch
svn merge %URL%/A_COPY merge_tests-1\A_COPY_2
svn ci -m "" merge_tests-1
]]]
# cwd == parent of merge_tests-1
>svn pl -vR merge_tests-1
Properties on 'merge_tests-1\A_COPY':
svn:mergeinfo : /A:1
Properties on 'merge_tests-1\A_COPY_2':
svn:mergeinfo : /A:1-3
/A_COPY:3-5
# Merge all outstanding revisions from second
# branch back to our "trunk" 'A'
>svn merge %URL%/A_COPY_2 merge_tests-1/A
--- Merging revisions 5-6:
U merge_tests-1\A\B\lambda
U merge_tests-1\A\mu
U merge_tests-1\A
# 'A' is missing mergeinfo from 'A_COPY':
>svn pl -vR merge_tests-1
Properties on 'merge_tests-1\A':
svn:mergeinfo : /A_COPY_2:5-6
Properties on 'merge_tests-1\A_COPY':
svn:mergeinfo : /A:1
Properties on 'merge_tests-1\A_COPY_2':
svn:mergeinfo : /A:1-3
/A_COPY:3-5
A parting thought, while debugging 'svn merge %URL%/A_COPY_2
merge_tests-1/A' the svn_wc_diff_callbacks2_t dir_props_changed, i.e.
merge.c:merge_props_changed(), calls svn_wc_merge_props() on "A" and
passes original_props which contain '/A:1-3'. This seems odd, since 'A'
has no mergeinfo prior to the merge(?).
