Bug 391795 – Migrate releng repository to git

• Status: RESOLVED FIXED
• Product: Gentoo Infrastructure

[Description Jorge Manuel B. S. Vicetto (RETIRED) 2011-11-24 18:28:54 UTC]

The release team would like to migrate the releng repository[1] to git.
We will need to keep access to both repos while we test the migration and update the scripts to use the new repo.

I'm pretty sure the overlays team is more suited for migrations.. ?

[Comment 2 Sebastian Pipping 2011-11-25 03:08:58 UTC]

Speaking for myself: no time for this before January.

Is releng aware that they could technically do the actual conversion of the SVN history using dev-vcs/svn2git or git-svn and dev-vcs/svneverever themselves and only leave setup of a new git repo to push to to infra or the overlays team?

[Comment 3 Christian Ruppert (idl0r) 2011-11-25 18:17:56 UTC]

infra.. at least for now. I think we're going to use git.gentoo.org instead.

Any progress? :)

Create svn2git identity mapping from userinfo.xml

Results
=======
Please check the output of the conversion at
http://git.overlays.gentoo.org/gitweb/?p=proj/releng.git;a=summary

The group of comitters is

  @releng = agaffney angelos armin76 dertobi123 jmbsvicetto
              kingtaco klausman kumba mattst88 nightmorph
              ranger redhatter robbat2

but these devs have not pubkeys in gitolite as of now:

  dertobi123, klausman, kumba, ranger, redhatter


On the process
==============
Seems to be a single branch ("trunk") only.

Conversion was done using dev-vcs/svn2git-1.0.5 with command

  # svn2git --rules=rules --identity-map=identity --add-metadata \
      --stats releng-rsync/

The svn repo was ripped using

  # rsync -a rsync://anonvcs.gentoo.org/vcs-public-svnroot/releng/ releng-rsync

The identity mapping was extracted from userinfo.xml using the script attached.
The rules file is rather trivial:

  create repository releng.git
  end repository

  match /trunk/
    repository releng.git
    branch master
  end match

  match /branches/
  end match

  match /tags/
  end match

Releng, please close the bug if the results are sufficient.

We have a tool, scripts/fetch-ssh-key.pl that fetches keys from LDAP easily. I wasn't sure if you were aware of the tool already, but anyway I've added those devs in gitolite now.

Sebastian,

let me start by thanking you for the conversion.
I've given a quick look through gitweb and it looks ok. Let me clone it locally and give it a more thorough look before I close this bug.

@releng:
Has anyone else checked the git repo?
