Procedure

Please read the whole procedure first to understand what's going on.

Dump SOURCE repository

First you should dump the whole source repository (making of partial dump is NOT possible) using svnadmin dump command.

svnadmin dump PATH_TO_SOURCE_REPO_IN_LOCAL_FS > SOURCE_REPO.dump

• for $SVNOFF — /afs/cern.ch/project/svn/reps/atlasoff
• for $SVNGRP — /afs/cern.ch/project/svn/reps/atlasgrp
• for $SVNUSR — /afs/cern.ch/project/svn/reps/atlasusr

Filter it out

cat SOURCE_REPO.dump | svndumpfilter --drop-empty-revs --renumber-revs --skip-missing-merge-sources include SOURCE_FOLDER > SOURCE_FOLDER.dump

Run realloc.py if needed

If svn folder is going to be moved to different location you should reallocate it in SOURCE_FOLDER.dump using realloc.py script which could be downloaded from $SVNUSR/cibak/svnRealoc/realloc.py URL. The usage is very simple, you have to specify two parameters:

• source directory (as absolute path but WITHOUT leading backslash) as --src option parameter
• destination directory (as absolute path but WITHOUT leading backslash) as --dest option parameter

cat SOURCE_REPO.dump | realloc.py --src SOURCE_FOLDER --dest DEST_FOLDER > DEST_FOLDER.dump

Load dump to the new location

Load dump to the DESTINATION repository using svnadmin load command:

svnadmin load [--parent PARENT_DIR] PATH_TO_DEST_REPO_IN_LOCAL_FS  < DEST_FOLDER.dump

Make sure that PARENT_DIR is created in DESTINATION repository before loading!

Chain it, please!

Dumping SOURCE repo, filtering it out and reallocation could be done in one command:

svnadmin dump PATH_TO_SOURCE_REPO_IN_LOCAL_FS | svndumpfilter --drop-empty-revs --renumber-revs --skip-missing-merge-sources include SOURCE_FOLDER | realloc.py --src SOURCE_FOLDER --dest DEST_FOLDER > DEST_FOLDER.dump

Clean up

Remove svn rights in SOURCE repository for SOURCE_FOLDER and copy them to the DESTINATION repository to DEST_FOLDER. Inform developers that SOURCE_FOLDER has been reallocated to the DESTINATION repository under DEST_FOLDER.

Example

Let's say somebody will ask you for moving $SVNUSR/cibak/devView package to $SVNGRP under /Institutes/AGH-UST. Also somebody will ask you to rename the package from devView to RTTWebPage.

1. dumping, filtering and reallocationg

   svnadmin dump /afs/cern.ch/project/svn/reps/atlasusr | \
   svndumpfilter --drop-empty-revs --renumber-revs --skip-missing-merge-sources include cibak/devView | \
   realloc.py --src cibak/devView --dest RTTWebPage > rttWebPage.dump
   

2. creation of destination parent directory (if not there already)

   svn mkdir $SVNGRP/Institutes/AGH-UST -m "top level directory for AGH-UST"
   

3. loading

   svnadmin load --parent-dir /Institutes/AGH-UST /afs/cern.ch/project/svn/reps/atlasgrp < rttWebPage.dump
   

4. removing rights and granting them is rather simple, isn't it?
