Hi there good folk of the git community,
Next week, I'll be presenting a summary of the past 2 years work
on improving svn interoperability for git.
I'm requesting feedback from anyone who cares with regard to
what they'd like to hear about.
http://linux.conf.au/schedule/158/view_talk?day=friday
Jonathan put together an overview for Dmitry in preparation for
Google Summer of Code 2011:
svn-fe is very young, so a sufficiently bored person (meaning: I am
not advocating that you do this; this is just an excuse to provide
references to avoid getting stuck when you have questions) could
probably read its history in full without getting lost. Here are some
references on the initial design (i.e., how responsibility is divided
between the svndump driver and repo_tree and fast_export modules).
The division of responsibilities between modules mostly survives,
while the details of mechanism are quite different now.
announcement and following thread:
http://thread.gmane.org/gmane.comp.version-control.git/143180/focus=143388
http://thread.gmane.org/gmane.comp.version-control.git/143187
first public review (not much big picture stuff yet):
http://thread.gmane.org/gmane.comp.version-control.git/147587
second review (focuses on infrastructure, most of which is
obsolete now :))
http://thread.gmane.org/gmane.comp.version-control.git/148409
third review (some serious thoughts about design begin here)
http://thread.gmane.org/gmane.comp.version-control.git/148866/focus=149097
fourth review (with a program to test with based on David's original
program; review mentions some unresolved wishes: appropriate
incremental import bookkeeping, properties, empty directories)
http://thread.gmane.org/gmane.comp.version-control.git/149571/focus=149934
fifth review, which is the one that stuck.
http://thread.gmane.org/gmane.comp.version-control.git/151086/focus=151144
Also of note is the contributions made by Ram in 2010 that eventually
became a headlining feature for Subversion 1.7:
http://subversion.apache.org/docs/release-notes/1.7.html#svnrdump
Dmitry ended up submitting a number of short and pointy series.
My favourite by far was:
fast-import: improve deltas for blobs
http://thread.gmane.org/gmane.comp.version-control.git/179774
This optimisation was glaring in hindsight.
Respect to Dmitry for spotting it.
I believe a number of people have been contributing to the
remote helper infrastructure lately. They also deserve credit.
Maybe a better historian than myself can provide additional links.
The overhanging issue after all this work is that there are about
95 outstanding patches waiting to be detangled and resubmitted.
I regret not having time to complete this exercise myself.
I hope the process has been insightful and maybe to renew some
interest. Thanks for reading.

Nice. As a lay person attending the conference, here are a few things
I think I'd like to hear:
- Why this project is so challenging compared to say, a git-hg bridge
or a git-darcs bridge. What makes Subversion especially hard to deal
with?
- What is the biggest motivation for developing the svnrdump/ svnrload
combination? Are there any other usecases for the tools?
- How has this project contributed to the development of the
fast-import infrastructure? Can these changes be used to improve
other/ future remote helpers?
- You've spoken about exporting Subversion history to Git so far, but
what about the reverse? Which parts of the picture are still missing?
Thanks.

Thank you for the feedback, it helped a lot with picking a trajectory.
Video is now available: http://youtu.be/0hVuv-wv4Dw
Slides: http://barrbrain.github.com/vcs-interoperability.html
It was my first conference presentation so the usual caveats apply.
I was fortunate to have a small but interested audience.
I look forward to constructive criticism so that I can better represent
our community to the folk Down Under.

Thanks for the valuable criticism. A few thoughts:
1. We'll try to fix this over the next few weeks.
2. Subversion's architecture is well-compartmentalized: is this what
leads to communication gaps between the API layers?
3. What are your thoughts on lib'ifying Git so that others can call
into it using an API?
Cheers!

This is something that everyone agrees would be a good thing. There have
been many people who have started projects to do so, but they have all
stalled.

I believe libgit2 is still under active development.

Yes, GitHub alone actually has 2 full time employees and 1 contractor
who are entirely dedicated to the project. It also ships with the
GitHub for Mac product, so it's used in production by tens of
thousands every day. If any of you want to get involved, you can check
out the mailing list (libgit2@librelist.org) or (probably more
usefully) the GitHub project page:
https://github.com/libgit2/libgit2
Open tickets, contribute code, review PRs, etc.

I'm thinking libgit2 is where git features that have stablised are formalised.
On the other hand, git-core is where features are incubated.
I would like to see fast-import ported to libgit2 when it stabilises ;)
After giving my talk, I feel compelled to reroll the historic vcs-svn series.
I'm pushing as I go to my GitHub account:

Just some quick notes to save some time:
All the commits on the
git://repo.or.cz/git/jrn.git svn-fe
branch were known-good in the sense that they seemed sane enough to
build on and I do not think they need any reorganization or other
work. Maybe that could help bootstrap your efforts?
The svn-fe-pu branch includes some other patches: some optimizations
which are probably safe, the demo helper that allows "git clone
svn-alpha::<url>", some transport-helper patches to support the
latter, and so on. They are not vetted. If anyone sends patches from
that branch, or any other patch for that matter, to the list and cc-s
me, I'll be happy to review them. Here's a shortlog for convenience:
David Barr (2):
fast-import: allow object_table to grow dynamically
fast-import: allow atom_table to grow dynamically
Dmitry Ivankov (2):
Arrange a backflow pipe from fast-importer to remote helper stdin
Add alpha version of remote-svn helper
Jonathan Nieder (12):
work around ISO C incompatibility between data and function pointers
ensure initializer elements are computable at load time
enums: omit trailing comma for portability
notes: avoid C99-style comment
notes merge: eliminate OUTPUT macro
make sure initializers are computable at load time
fast-import: allow branch_table to grow dynamically
fast-import: use DIV_ROUND_UP
svn-fe: add a program that generates a notes-to-svn-revs mapping
svn-fe: do not rely on /bin/env utility to launch remote helper
svn-fe: use tabs to indent in remote helper script
remaining warnings
Test results from the svn-fe branch would be interesting. I am
particularly nervous about asking Junio to pull changes to
contrib/svn-fe that might break it at the same time as making the
interface changes needed for support of the "svnadmin dump
--incremental" format without much testing since it would be painful
to back them out. But probably that's moot, since after this long
while there still hasn't been anyone testing it.

Eh, you only live once.
Junio, please pull
git://repo.or.cz/git/jrn.git svn-fe
to get the following changes since commit ec014eac0e9e6f30cbbca616090fa2ecf74797e7:
Git 1.7.5 (2011-04-23 23:36:32 -0700)
up to c5bcbcdcfa1e2a1977497cb3a342c0365c8d78d6:
vcs-svn: reset first_commit_done in fast_export_init (2011-06-23 10:04:36 -0500)
I'd even be okay with pulling this for v1.7.9, but application for the
next release would also be fine with me. It simplifies svn-fe a great
deal and fulfills a longstanding wish: support for dumps with deltas
in them. The cost is that commandline usage of the svn-fe tool
becomes a little more complicated since it no longer keeps state
itself but instead reads blobs back from fast-import in order to copy
them between revisions and apply deltas to them.
Sorry I've taken so long to get to this, and thanks to David for the
prodding.
----------------------------------------------------------------

vcs-svn: set up channel to read fast-import cat-blob response
vcs-svn: quote paths correctly for ls command

vcs-svn: drop string_pool
vcs-svn: drop treap

Thank you, Jonathan. I forgot our prior discussion about avoiding yet
another history rewrite. This provides a nice cut-point.
I do think we need to gather Dmitry's work on svn-fe and propose a
front-end for core so that it is no longer relegated to contrib.

Yep. Should such a remote helper link directly to the vcs-svn lib, or
would it make sense to start with a script that makes use of svn-fe
(possibly with a different name once it is hoisted out of contrib)?

Thanks, but will pull after 1.7.9 that was scheduled to happen today.
By the way, we should have done a GPG keysigning at the last GitTogether.
The above paragraph ("The series simplifies svn-fe a great deal...") could
have been recorded in the message body of a signed tag, and we could have
started eating our own dogfood, now even Linus and his lieutenants are
using the upcoming 1.7.9 feature.

Curious; this series seem to be based on a codebase that is older than
6908e99 (Revert "t0081 (line-buffer): add buffering tests", 2011-03-30).
Not complaining, not asking any question. Just making an observation.

There were some conflicts, but I think I resolved correctly. Please
double-check what appears in 'pu'.
Thanks.
