I'm trying to use the Subversion merge --reintegrate feature to merge a development branch back to the project trunk. Subversion version 1.6.17 on Fedora 14.

I get the following [me@fedora14 product_trunk]$ svn merge --reintegrate ^/product/branches/NewFeature svn: Retrieval of mergeinfo unsupported by 'svn://fedorabox/e2458/branches/ErrtsFeaturDev'

I've checked versions of svnserve and svn client. These are both 1.6.17 -which should support the reintegrate feature. [root]# svnserve --version svnserve, version 1.6.17 (r1128011) compiled Jun 2 2011, 15:24:04 ... [root]# svn --version svn, version 1.6.17 (r1128011) compiled Jun 2 2011, 15:24:04

I've also checked the dates on apache svn modules (am I using apache with svn:// ?) The dates check out . [me@fedora14 modules]$ ls -l *svn* -rwxr-xr-x. 1 root root 13520 Jun 3 2011 mod_authz_svn.so -rwxr-xr-x. 1 root root 155328 Jun 3 2011 mod_dav_svn.so

This Fedora 14 machine has been updated from an earlier version of Fedora, so our Subversion repository was most likely initially created with a pre-1.5 Subversion. I think this could be my problem, but I can't find anything indicating what if anything needs to be changed.

Thanks in advance.

Follow-up to bahrep:

your server and client may be rather fresh versions, but it's also "format of repository", changed over time (and rleases)… and new versions of tools are backward-compatible with old formats. Check value from db/formatfile (on FS of repository, not file in repo), it have to be less than "Format 3", which is minimal requirements of merge-tracking. And yes, svn upgrade repository

  • Thanks Bahrep and Lazy Badger. The db/formatfile indicates it is version 2. Looks like this is my problem. svnadmin upgrade looks like the answer. Sep 30, 2018 at 12:34

The problem is that the server or the repository format is old and does not support svn:mergeinfo. Therefore, your merge behavior should correspond to SVN 1.4 or older (see SVNBook 1.4).

Note that svn:mergeinfo was introduced in SVN 1.5.0 (released on 19 June 2008). It definitely makes sense to upgrade your SVN client and server to the latest version 1.10.x and run the svnadmin upgrade command to upgrade the format of your repositories.

Generally speaking, you are now missing all the new features and improvements introduced in SVN after ~2008 year.

  • Hi Bahrep. Like it says in the post, the svn version is 1.6.17. the problem was that the database format wasn't updated when svn was updated, so that database file format (db/formatfile) is still 2. As you mentioned, svnadmin upgrade looks like what I need. Sep 30, 2018 at 12:39
