Last February I installed two OpenProjects instances for two large “multi-projects” I am managing for two institutions.
I chose your openproject-ce on Ubuntu 14.04 OpenStack instances. I configured openproject-ce serving thru HTTPS

A week ago the teams of one of them finally started developing code and so I activate the subversion built-in support.
I discovered that subversion is served as WEBDAV https thru https://server/svn/projectid
We started testing checking, commits, etc. All well.

But we have got stuck at tagging and branching.

I read a lot about it and discovered that there must be additional directives in svn_dav.conf for managing three issues:

1) O (n) svn COPY operations due to authorization/locking tree crawling.

This is referenced in:
http://subversion.apache.org/faq.html#dav-slow-copy

With a workaround as these directives in /svn location

SetEnvIf Request_Method COPY method_is_copy
RequestHeader set Depth 0 env=method_is_copy

Or an alternative for Apache >2.4 as

<If “%{REQUEST_METHOD} == ‘COPY’”>
RequestHeader set Depth 0

2) COPY WEBDAV about locking
Here you can see: https://bz.apache.org/bugzilla/show_bug.cgi?id=55306

The problem is that the “If:” header is sent in some place in the chain
No idea how to resolv it!

3) Finally it seems that tagging / branching operations thru COPY thru HTTPS needs another directive

In the github openproject repositories the file: doc/subversion_and_git_integration.md
says that the following directive must be added

RequestHeader edit Destination ^https: http: early

But doen’t work in community edition

I have tried several combinations, no success, no tagging

My question is: Have you seen those issues before?
Any tips?

Thanks,
