We have a problem with the new 1.8 subversion clients (we use TortoiseSVN 1.8.5 and SlikSVN 1.8.5). It seems that the new SVN 1.8 feature of being able to keep using your feature branch after reintegration is not working in some cases. It is not working when the trunk contains local mergeinfo (Mergeinfo on files or sub-trees). This may cause a problem for branch reuse after the reintegrate. This wasn't a problem with 1.7 clients if branch reuse was done using the 'keep alive dance' (using the record only option). I have made a script that illustrates this problem from scratch. It can be run against an empty repository using a 1.8 client. The script below has 10 steps. Step 1-5 are used to create the starting situation of having local mergeinfo in the trunk. Steps 6-9 simulate changes being made to the trunk during the life of a feature branch2. Step 10 is the failing step which simulates the first step of reuse of the feature branch after reintegrate. This is the error in step 10: svn: E195016: Reintegrate can only be used if revisions 346 through 349 were previously merged from svn://svn2010/practice/branches/featurebranch2 to the reintegrate source, but this is not the case: trunk/file1.txt Missing ranges: /trunk/file1.txt:347 This is the script. You need to change the subversion URL's to point to your repository. I do not understand why this happens. Also the error reports missing ranges of file1.txt while it seems to be file2.txt that is missing mergeinfo. While not a solution, deleting the local mergeinfo on file2.txt in the trunk also seems to fix the problem. This also hints that the error message is reporting something on the wrong file. @ECHO OFF ECHO ------------------------------------------------------------------ ECHO STEP 1: Create a trunk with 2 files ECHO ------------------------------------------------------------------ svn mkdir -m "Create trunk" svn://svn2010/practice/trunk svn checkout svn://svn2010/practice/trunk echo Original file contents created in the trunk. > trunk\file1.txt echo Original file contents created in the trunk. > trunk\file2.txt svn add trunk\file1.txt svn add trunk\file2.txt svn -m "Added 2 files" commit trunk ECHO ------------------------------------------------------------------ ECHO STEP 2: Create a copy (feature branch) from the trunk ECHO ------------------------------------------------------------------ svn mkdir -m "Create branches dir" svn://svn2010/practice/branches svn copy -m "Create featurebranch1" svn://svn2010/practice/trunk svn://svn2010/practice/branches/featurebranch1 ECHO ------------------------------------------------------------------ ECHO STEP 3: Modify both files in the feature branch ECHO ------------------------------------------------------------------ svn checkout svn://svn2010/practice/branches/featurebranch1 echo Additional file contents created in featurebranch1. >> featurebranch1\file1.txt echo Additional file contents created in featurebranch1. >> featurebranch1\file2.txt svn -m "Modified 2 files in featurebranch1" commit featurebranch1 ECHO ------------------------------------------------------------------ ECHO STEP 4: Merge both files from featurebranch1 to the trunk to ECHO create local mergeinfo on both files ECHO ------------------------------------------------------------------ svn update trunk svn merge svn://svn2010/practice/branches/featurebranch1/file1.txt trunk/file1.txt svn merge svn://svn2010/practice/branches/featurebranch1/file2.txt trunk/file2.txt svn -m "Merged 2 files from featurebranch1 to trunk" commit trunk ECHO ------------------------------------------------------------------ ECHO STEP 5: Delete featurebranch2, we only needed it for the ECHO initial setup ECHO ------------------------------------------------------------------ svn delete -m "Delete featurebranch1" svn://svn2010/practice/branches/featurebranch1 ECHO ------------------------------------------------------------------ ECHO STEP 6: This is the start of the problematic scenario ECHO Create a new featurebranch2 from the trunk and a wc for it ECHO ------------------------------------------------------------------ svn copy -m "Create featurebranch2" svn://svn2010/practice/trunk svn://svn2010/practice/branches/featurebranch2 svn checkout svn://svn2010/practice/branches/featurebranch2 ECHO ------------------------------------------------------------------ ECHO STEP 7: Modify the contents of file1.txt in the trunk and leave ECHO the contents of file2.txt unchanged (this is important) ECHO ------------------------------------------------------------------ echo Additional file contents created in the trunk. >> trunk\file1.txt svn -m "Modified file1.txt in the trunk" commit trunk ECHO ------------------------------------------------------------------ ECHO STEP 8: Sync merge the trunk to featurebranch2 ECHO ------------------------------------------------------------------ svn update featurebranch2 svn merge svn://svn2010/practice/trunk featurebranch2 svn -m "Sync merged the trunk into featurebranch2" commit featurebranch2 ECHO ------------------------------------------------------------------ ECHO STEP 9: Reintegrate featurebranch2 back into the trunk ECHO ------------------------------------------------------------------ svn update trunk svn merge svn://svn2010/practice/branches/featurebranch2 trunk svn -m "Reintegrated featurebranch2 back into the trunk" commit trunk ECHO ------------------------------------------------------------------ ECHO STEP 10: Try to reuse featurebranch2 after it was reintegrated ECHO Sync merge it from the trunk.
