SVN how to resolve new tree conflicts when file is added on two branches

Question

When merging a couple of branches  using SVN 1 6 1  where a file has been added on both branches  and then worked on in those separate branches  I m getting one of the new tree conflicts         C foo txt    gt    local obstruction  incoming add upon merge   I need the changes from both branches  but the tree conflict doesn t give me the usual  working   merge-left  amp   merge-right files -- which is understandable due to the nature of the conflict  There are quite a few of these conflict  and ones where a delete of the same file has occurred on each branch  but they re simple to resolve   How can I resolve this issue  The SVN redbean book  for 1 6  doesn t cover this situation

I found a post suggesting a solution for that  It s about to run   svn resolve --accept working  lt YourPath gt    which will claim the local version files as OK  You can run it for single file or entire project catalogues

As was mentioned in an older version  2009  of the  quot Tree Conflict quot  design document   XFAIL conflict from merge of add over versioned file This test does a merge which brings a file addition without history onto an existing versioned file  This should be a tree conflict on the file of the  local obstruction  incoming add upon merge  variety  Fixed expectations in r35341    This is also called  quot evil twins quot  in ClearCase by the way   a file is created twice  here  quot added quot  twice  in two different branches  creating two different histories for two different elements  but with the same name  The theoretical solution is to manually merge those files  with an external diff tool  in the destination branch  B2   If you still are working on the source branch  the ideal scenario would be to remove that file from the source branch B1  merge back from B2 to B1 in order to make that file visible on B1  you will then work on the same element   If a merge back is not possible because merges only occurs from B1 to B2  then a manual merge will be necessary for each B1- gt B2 merges

I just managed to wedge myself pretty thoroughly trying to follow user619330 s advice above   The situation was   1   I had added some files while working on my initial branch  branch1   2  I created a new branch  branch2 for further development  branching it off from the trunk and then merging in my changes from branch1  3  A co-worker had copied my mods from branch1 to his own branch  added further mods  and then merged back to the trunk   4  I now wanted to merge the latest changes from trunk into my current working branch  branch2   This is with svn 1 6 17   The merge had tree conflicts with the new files  and I wanted the new version from the trunk where they differed  so from a clean copy of branch2  I did an svn delete of the conflicting files  committed these branch2 changes  thus creating a temporary version of branch2 without the files in question   and then did my merge from the trunk   I did this because I wanted the history to match the trunk version so that I wouldn t have more problems later when trying to merge back to trunk   Merge went fine  I got the trunk version of the files  svn st shows all ok  and then I hit more tree conflicts while trying to commit the changes  between the delete I had done earlier and the add from the merge   Did an svn resolve of the conflicts in favor of my working copy  which now had the trunk version of the files   and got it to commit   All should be good  right   Well  no   An update of another copy of branch2 resulted in the old version of the files  pre-trunk merge    So now I have two different working copies of branch2  supposedly updated to the same version  with two different versions of the files  and both insisting that they are fully up to date   Checking out a clean copy of branch2 resulted in the old  pre-trunk  version of the files   I manually update these to the trunk version and commit the changes  go back to my first working copy  from which I had submitted the trunk changes originally   try to update it  and now get a checksum error on the files in question   Blow the directory in question away  get a new version via update  and finally I have what should be a good version of branch2 with the trunk changes   I hope   Caveat developer
