Hi there, we've successfully migrated from CVS to SVN recently and we are now facing an oddity during merging. We are using Subversion 1.6.17 on client and server.
Repository structure is like this: /ourstuff/ourproduct/1.0/MODULES/mod_a /ourstuff/ourproduct/1.0/MODULES/mod_b /ourstuff/ourproduct/1.0/MODULES/... -> mod_a ... mod_x get's branched (=copied) to customer dev branch /customer/project/1.x/dev/MODULES/mod_a /customer/project/1.x/dev/MODULES/mod_b /customer/project/1.x/dev/MODULES/... -> from there the modules are branches (=copied) to customer prod branch /customer/project/1.x/dev/production/MODULES/mod_a /customer/project/1.x/dev/production/MODULES/mod_b /customer/project/1.x/dev/production/MODULES/... Then, merges are performed from ourproduct->project/dev, then project/dev->project/dev/production. (We chose this non-standard branch scheme because we can see branch relationship that way and also svnsync only the customer-relevant part of the repository.) Now we had a mysterious conflict popping up. The first merge ourproduct->project/dev worked fine but the merge project/dev to project/dev/production produces conflicts on the svn:mergeinfo property. The strange thing is: There is no svn:mergeinfo on the source module (say ourproduct/MODULES/mod_a) BUT an empty one has been created on the branched module (dev/MODULES/mod_a). > svn log --stop-on-copy ^/customer/project/1.x/dev/MODULES/mod_a [...] r27322 | ... [...] A /customer/project/1.x/dev/MODULES/mod_a (from /ourstuff/ourproduct/version/MODULES/mod_a:127321) > svn proplist -v -r27322 ^/ourstuff/ourproduct/1.0/MODULES/mod_a (no output) > svn proplist -v -r27322 ^/customer/project/1.x/dev/MODULES/mod_a Properties on '$REPOURL/customer/project/1.x/dev/MODULES/mod_a': svn:mergeinfo The same empty property is of course copied to dev/production/MODULE/mod_a and causes a conflict when merging from dev to production. The file dir_conflicts.prej contains: > Trying to change property 'svn:mergeinfo' from '' to > '/ourstuff/ourproduct/version/MODULES/mod_a:27322-27324', but it has > been locally deleted. The property has not been deleted - it was there, but empty: > svn proplist -v ^/customer/project/1.x/dev/production/MODULES/mod_a Properties on '$REPOURL/code/customer/project/1.x/dev/production/MODULES/mod_a': svn:mergeinfo The directory properties after merging are: > svn proplist -v . Properties on '.': svn:mergeinfo /customer/project/1.x/dev/MODULES/mod_a:27324-27341 -> correct. So my questions are: 1. Where does the empty svn:mergeinfo come from? (Might it be connected to one spurious svn:mergeinfo somewhere down in mod_a in the source branch?) 2. How may I prevent further conflicts?
