Download migration utilities

For an easy reference in this guide, the migration scripts is downloaded in the home folder: 

 cd $HOME &&  wget https://bitbucket.org/atlassian/svn-migration-scripts/downloads/svn-migration-scripts.jar

Install git-svn

Ubuntu

On Ubuntu, if you you get this output: 

$ java -jar ./svn-migration-scripts.jar verify  
svn-migration-scripts: using version 0.1.56bbc7f 
Git: using version 2.17.1  
Subversion: using version 1.9.7
git: 'svn' is not a git command. See 'git --help'.
The most similar commands are
fsck
mv
show
git-svn: ERROR: Unable to determine version.

You must install the git-svn package by running: 

$ sudo apt install git-svn

Now, you will get something like this: 

$ java -jar ./svn-migration-scripts.jar verify
svn-migration-scripts: using version 0.1.56bbc7f
Git: using version 2.17.1
Subversion: using version 1.9.7
git-svn: using version 2.17.1

Mount a case-sensitive disk image (for Mac OS)

Check if this step is needed by running: 

java -jar ~/svn-migration-scripts.jar verify
 
svn-migration-scripts: using version 0.1.56bbc7f
Git: using version 2.11.0
Subversion: using version 1.9.4
git-svn: using version 2.11.0
You appear to be running on a case-insensitive file-system. This is unsupported, and can result in data loss.

Following the warning, we create a disk image dedicated to the migration activities: 

java -jar ~/svn-migration-scripts.jar create-disk-image 5 GitMigration
 
created: /Users/manuelesimi/GitMigration.sparseimage
/dev/disk2     		 GUID_partition_scheme     		 
/dev/disk2s1   		 EFI                       		 
/dev/disk2s2   		 Apple_HFS                 		 /Users/manuelesimi/GitMigration
The disk image was created successfully and mounted as: /Users/manuelesimi/GitMigration

Extract the author(s) information

 cd ~/GitMigration
 java -jar ~/svn-migration-scripts.jar authors https://svn.d4science.research-infrastructures.eu/gcube/trunk/Common/gxREST  > authors.txt
About to create the authors file.


Alternative (pure SVN): 

svn co https://svn.d4science.research-infrastructures.eu/gcube/trunk/Common/gxREST
cd gxREST
svn log -q | awk -F '|' '/^r/ {sub("^ ", "", $2); sub(" $", "", $2); print $2" = "$2" <"$2">"}' | sort -u > authors.txt

Edit the authors file

You need to edit the file and add the correct email address (i.e. the address configured in the Git service) for each listed author: 

> cat authors.txt
luca.frosini = luca.frosini <luca.frosini@mycompany.com>
lucio.lelii = lucio.lelii <lucio.lelii@mycompany.com>
manuele.simi = manuele.simi <manuele.simi@mycompany.com
> vi authors.txt
 
> cat authors.txt
luca.frosini = luca.frosini <luca.frosini@isti.cnr.it>
lucio.lelii = lucio.lelii <lucio.lelii@isti.cnr.it>
manuele.simi = manuele.simi <manuele.simi@isti.cnr.it>

Clone the SVN repository

git svn clone --authors-file=authors.txt --follow-parent  https://svn.d4science.research-infrastructures.eu/gcube/trunk/Common/gxREST --username manuele.simi gxRest
 
Note: --follow-parent makes it slower, but it’s needed if the SVN folder has been moved around.
