#+title: Prepare test_converters.py it tests
#+author: ardumont
* Requisite:
#+BEGIN_SRC sh
sudo apt install subversion git-svn
#+END_SRC
* Create mirror repository
Then:
#+BEGIN_SRC sh
./init-svn-repository.sh /home/storage/svn/repos/pkg-gourmet svn://svn.debian.org/svn/pkg-gourmet/
#+END_SRC
Note:
Saved as ../../../../bin/init-svn-repository.sh
And now we have a mirror svn repository at file:///home/storage/svn/repos/pkg-gourmet
* git-svn policy
`git svn clone` the repository and parse the git log entries for the needed data.
#+BEGIN_SRC sh
git svn clone file:///home/storage/svn/repos/pkg-gourmet -q --no-metadata
cd pkg-gourmet
# commit
git log --format=raw --reverse | grep '^commit ' | awk '{print $2}'
# tree
git log --format=raw --reverse | grep '^tree ' | awk '{print $2}'
#+END_SRC
Those are the data to check when done parsing the repository:

* swh policy
** New repository
For this one this was more tedious.
#+BEGIN_SRC sh
$ svn export --ignore-keywords file:///home/storage/svn/repos/pkg-gourmet@1
#+END_SRC
The export does not expand the keywords and does not include the .svn folder.
Then:
#+BEGIN_SRC sh
$ cd pkg-gourmet
$ swh-hashtree --path .
669a71cce6c424a81ba42b7dc5d560d32252f0ca
#+END_SRC
Note: ../../../../bin/hashtree
Then for the next revision:
#+BEGIN_SRC sh
cd .. ; rm -rf pkg-gourmet; svn export --ignore-keywords file:///home/storage/svn/repos/pkg-gourmet@2
A pkg-gourmet
A pkg-gourmet/gourmet
A pkg-gourmet/gourmet/trunk
Exported revision 2.
$ cd pkg-gourmet && swh-hashtree --path .
