Since a few years (I think it was with release 1.6.17 of subversion) the merge information shown from "svn log -g" has been changed. The new way to show merge logs means some improvements like less redundant information and better performance. Unfortunately, when using these newer versions of svn to gather information about merges I have found that some merge information is lost. For that reason I have stuck to version 1.6.16 for these purposes.
Now I have finally been able to create a small case where merge information is lost. In the example below I type the created revision in the left margin to make the commands and revisions easier to discuss: -8<----------------------------------------- svnadmin create /tmp/repo_test mkdir svn_work 1 svn import -m "" svn_work file:///tmp/repo_test/trunk 2 svn import -m "" svn_work file:///tmp/repo_test/branches rmdir svn_work svn checkout file:///tmp/repo_test/trunk svn_work echo hello > svn_work/hello.txt svn add svn_work/hello.txt 3 svn commit -m "" svn_work/ 4 svn copy -m "" file:///tmp/repo_test/trunk file:///tmp/repo_test/branches/1 echo hello world > svn_work/hello.txt 5 svn commit -m "" svn_work/ 6 svn copy -m "" file:///tmp/repo_test/trunk file:///tmp/repo_test/branches/2 svn switch file:///tmp/repo_test/branches/2 svn_work echo hello > svn_work/hello2.txt svn add svn_work/hello2.txt 7 svn commit -m "" svn_work/ svn switch file:///tmp/repo_test/branches/1 svn_work svn merge file:///tmp/repo_test/trunk svn_work 8 svn commit -m "" svn_work/ echo hello > svn_work/hello3.txt svn add svn_work/hello3.txt 9 svn commit -m "" svn_work/ svn switch file:///tmp/repo_test/trunk svn_work/ svn merge --reintegrate file:///tmp/repo_test/branches/1 svn_work 10 svn commit -m "" svn_work/ svn switch file:///tmp/repo_test/branches/2 svn_work svn merge file:///tmp/repo_test/trunk svn_work 11 svn commit -m "" svn_work/ svn switch file:///tmp/repo_test/trunk svn_work/ svn merge --reintegrate file:///tmp/repo_test/branches/2 svn_work 12 svn commit -m "" svn_work/ svn log -q -g file:///tmp/repo_test/trunk -8<----------------------------------------- Svn version 1.6.16 might give a little redundant information and is slower, but it gives one important log entry: ... ------------------------------------------------------------------------ r9 | henca | 2014-02-25 11:21:05 +0100 (Tue, 25 Feb 2014) Merged via: r10 ------------------------------------------------------------------------ ... The above log entry from svn 1.6.16 shows that branches/1 with latest revision 9 was merged back into trunk on revision 10. When using any newer version, up to and including the current 1.8.8 the information about the merge of branches/1 into trunk on revision 10 is lost: ------------------------------------------------------------------------ r12 | henca | 2014-02-25 13:06:18 +0100 (Tue, 25 Feb 2014) ------------------------------------------------------------------------ r11 | henca | 2014-02-25 13:06:17 +0100 (Tue, 25 Feb 2014) Merged via: r12 ------------------------------------------------------------------------ r9 | henca | 2014-02-25 13:06:15 +0100 (Tue, 25 Feb 2014) Merged via: r12, r11 ------------------------------------------------------------------------ r8 | henca | 2014-02-25 13:06:14 +0100 (Tue, 25 Feb 2014) Merged via: r12, r11 ------------------------------------------------------------------------ r4 | henca | 2014-02-25 13:06:12 +0100 (Tue, 25 Feb 2014) Merged via: r12, r11 ------------------------------------------------------------------------ r7 | henca | 2014-02-25 13:06:13 +0100 (Tue, 25 Feb 2014) ------------------------------------------------------------------------ r6 | henca | 2014-02-25 13:06:13 +0100 (Tue, 25 Feb 2014) ------------------------------------------------------------------------ r10 | henca | 2014-02-25 13:06:16 +0100 (Tue, 25 Feb 2014) ------------------------------------------------------------------------ r5 | henca | 2014-02-25 13:06:12 +0100 (Tue, 25 Feb 2014) ------------------------------------------------------------------------ r3 | henca | 2014-02-25 13:06:12 +0100 (Tue, 25 Feb 2014) ------------------------------------------------------------------------ r1 | henca | 2014-02-25 13:06:11 +0100 (Tue, 25 Feb 2014) ------------------------------------------------------------------------ This log is only affected by the version of svn used for the command "svn log", an older version of svn will still show the correct log of a repository created by a newer version of svn. If anyone want to play with my example I also have the commands without any revision number in the left margin: -8<----------------------------------------- svnadmin create /tmp/repo_test mkdir svn_work svn import -m "" svn_work file:///tmp/repo_test/trunk svn import -m "" svn_work file:///tmp/repo_test/branches rmdir svn_work svn checkout file:///tmp/repo_test/trunk svn_work echo hello > svn_work/hello.txt svn add svn_work/hello.txt svn commit -m "" svn_work/ svn copy -m "" file:///tmp/repo_test/trunk file:///tmp/repo_test/branches/1 echo hello world > svn_work/hello.txt svn commit -m "" svn_work/ svn copy -m "" file:///tmp/repo_test/trunk file:///tmp/repo_test/branches/2 svn switch file:///tmp/repo_test/branches/2 svn_work echo hello > svn_work/hello2.txt svn add svn_work/hello2.txt svn commit -m "" svn_work/ svn switch file:///tmp/repo_test/branches/1 svn_work svn merge file:///tmp/repo_test/trunk svn_work svn commit -m "" svn_work/ echo hello > svn_work/hello3.txt svn add svn_work/hello3.txt svn commit -m "" svn_work/ svn switch file:///tmp/repo_test/trunk svn_work/ svn merge --reintegrate file:///tmp/repo_test/branches/1 svn_work svn commit -m "" svn_work/ svn switch file:///tmp/repo_test/branches/2 svn_work svn merge file:///tmp/repo_test/trunk svn_work svn commit -m "" svn_work/ svn switch file:///tmp/repo_test/trunk svn_work/ svn merge --reintegrate file:///tmp/repo_test/branches/2 svn_work svn commit -m "" svn_work/ -8<----------------------------------------- regards Henrik
