These are the scripts and data used for the svn to git conversion of the FreeBSD repositories. Your help is requested in making sure the produced result is an acceptable representation of the current SVN repository. Fixing some few historical glitches are in scope if the effort is reasonable. Please let us know what you find.

git clone https://cgit-beta.freebsd.org/src.git && cd src
git config --add remote.origin.fetch '+refs/notes/*:refs/notes/*' && git fetch

Same for the doc and ports repos. You can expect some things to be different. Most importantly you should check whether branch and mergepoints (especially for vendor branches, but also project branches) are there and make sense.

• user/ branches are never merged back into master
• vendor tags are sometimes branches, sometimes tags, this is WIP.
• release/1.0_shipped et al. are snapshots of the checked out CVS source code, including expanded $Id$ tags.
• no other tags are expanded
• various vendor-foo suffixes have been collapsed into 1 vendor namespace, except for a few vendors where merging the userland and kernel bits is not straightforward due to how they interleave with the merge and branch history.

If you would want to run the conversion yourself and play with the rules, read on.

pkg install qmake qt5-core subversion git shlock

(for Debian: apt install qt5-qmake qtbase5-dev libapr1-dev libsvn-dev subversion git shlock)

A patched copy of svn2git aka. svn-all-fast-export has been added to this repo using: git subtree add --squash --prefix svn2git https://github.com/freebsd/svn2git master

cd svn2git && qmake && make && cd ..

You'll need to download a seed of the SVN repository dump (it takes weeks to bootstrap otherwise).

fetch https://download.freebsd.org/ftp/development/subversion/svnmirror-base-r358354.tar.xz
fetch https://download.freebsd.org/ftp/development/subversion/svnmirror-ports-r527184.tar.xz
fetch https://download.freebsd.org/ftp/development/subversion/svnmirror-doc-r53937.tar.xz
tar xf svnmirror-base-r358354.tar.xz
tar xf svnmirror-doc-r53937.tar.xz
tar xf svnmirror-ports-r527184.tar.xz

• (optional:) fetch the current SVN state using ./svnmir.sh -1
• convert either base, doc, or ports using ./git_conv { base | doc | ports }

Additional runs of svnmir.sh or git_conv will run incrementally.

On on moderately fast system with an SSD and/or enough RAM for the buffer cache, this should take about 2h to finish for src and will produce about 10GiB of intermediate data. The final src repo size should be around 1.7GiB.

While the conversion will try to convert all branches (except for some truly degenerate cases), we will only publish a small set of branches in the official repo, the other branches will be published to an archive repo.

• src will have: master, stable/N, releng/N, release/N.M, vendor/*
• doc will have: master, release/N.M
• ports will have: master, branches/YYYYQx

In the future, project branches will be individual forks of the repos.
