We have put a roadmap together with zerodeux. Need to schedule some time to
actually work on it now. We'll create a blank SVN repository ( around 30kb )
for each project. Then there's a bit of work on the access control and
permission stuff.

Hello Timothee, was is the current status of the svn system?

Hello all!
So, how long is long enough?! :(
-------------------------------------------------------
Date: Sun 11/28/2004 at 18:12 By: Timothee Besset <ttimo>
I'm slowly getting back to this after a long interruption due to changing
continents. Will have more news soon.

<http://dl.gna.org/admin/diagram.services.png> shows how Savane integrates
into Gna! services.
I intend to make (hum, at least to work with interested people) the necessary
changes for arch full support ASAP (currently we still abuse the download area
configuration) into Savane. Once it will be done, svn support should be
trivial (as soon as svn works on the subversion system, indeed).
-------------------------------------------------------

The svn chroot is already ready (at least deboostrap'ed). Right now, Mathieu
is working on the Arch subsystem migration first. And we have some issues with
DNS ans IPs, the svn.gna.org IP address is about to be available.
-------------------------------------------------------
Date: Mon 10/11/2004 at 05:23 By: Timothee Besset <ttimo>
I am on vacation until early November. I won't have net access. When I get
back, the subversion chroot should be ready for setup.
I'll probably start by getting SVN 1.1 and various svn tools packaged for
Sarge
-------------------------------------------------------

This task depends on task #760
(we hope being able to close #760 really soon)
-------------------------------------------------------
Date: Mon 09/13/2004 at 05:15 By: Timothee Besset <ttimo>
looks like we don't have any ETA of this happening anymore

Hello again!
So, did Timo won a free beer? :).
-------------------------------------------------------
Date: Fri 08/13/2004 at 02:59 By: Vincent Caron <zerodeux>
Hello people,
I regret I don't have the time to work on this, this is especially bad since
Timo is ready to give a hand. My daily job planning totally got out of
control.
I'm having real vacations starting from tomorrow, for 10 days. What I'll do is
setup the chroot for Timo and help him in two weeks. If it's not done, Timo
wins a free beer :).
BTW, could also be the occasion to have our first Sarge subsystem, I guess
Woody won't be enough for proper svn support.
-------------------------------------------------------

Does this have to be done on the Gna! machines? If not, I can try and set-up
a Debian chroot on one of my boxes, if that might help things :)
-------------------------------------------------------
Date: Tue 08/10/2004 at 08:14 By: Timothee Besset <ttimo>
Actually zerodeux is not on vacation, he is just very busy with real life. I
would have some time to spare to get this started, but I can't do anything
without a chrooted box to work from.
-------------------------------------------------------
Date: Tue 08/10/2004 at 08:07 By: Elfyn McBratney <beu>
Most of (all?) the Gna! admins that are working on this are on a well deserved
holiday. I guess they should have known taking a holiday in the sun would
upset you..

Hello, there!
I'm unhappy to see than SVN doesn't work till now, when task #500 'is almost
complete...' and so on ;(
-------------------------------------------------------
Date: Thu 06/17/2004 at 03:55 By: Vincent Caron <zerodeux>
Hello,
sorry, there is still a dependent task I need to finish (improve the remote
backup), and I need to be able to allocate a large contiguous chunk of time
for this. Which was kind of hard those last two weeks :(.
I'm still commited to setup that svn thing, I promiss :).
-------------------------------------------------------
Date: Wed 06/16/2004 at 20:24 By: Eugene Sizikov <eugene_beast>
Again, how it's going? Two weeks are gone...
-------------------------------------------------------
Date: Sat 05/29/2004 at 09:53 By: Timothee Besset <ttimo>
We'll start setting up an experimental server for subversion stuff within the
next two weeks I think. atm it mostly depends on zerodeux's availability, and
after that it will depend on mine
-------------------------------------------------------
Date: Sat 05/29/2004 at 08:54 By: Eugene Sizikov <eugene_beast>
So, how it's going? I sorta like Subversion and waiting for its presence here
at Gna! for bookeeping my project. When it's planned to got worked?
-------------------------------------------------------
Date: Tue 05/18/2004 at 03:08 By: Vincent Caron <zerodeux>
I've assigned two dependencies to this item :
* have a stable remote backup
* have updated admin docs
I'll do my best to fullfill them before the end of the month. It's just there
to help boring things to be done, and keep the general idea to only push an
experiment when everything else is rock solid.

Discussed with the svn developers for a bit, and I have some kind of plan
together. As I expected, they recommend DAV for scalability/stability.
There would be two root <Location> in apache conf, one under http for read
only (along with an online repository browser), and one under an https for
read write.
Using svnparentpath we can have a single <Location> and all the project
repositories stored below a single directory.
The read-write control would be performed through a pre-commit hook I think,
as it would work with svn over ssh as well, and is probably needed considering
the current user accounts strategy
-------------------------------------------------------

Incidentally, someone from Xiph would be interested in a 'GNUish forge' with
subversion support :

I would expect a good setup to be fairly low maintenance. There are a few
things to watch out for. If you consider Alioth, they had an appalling
permissions policy which was causing regular repository lockups.
For good scalability, the SVN developers recommend DAV transport (http/https)
over svnserve (ssh). I commonly use https for write access, SVN supports
client certificates but I never actually tried it. We can have ssh write
access, but it will involve a careful setup of permissions and umask.

For testing, why not doing that on maggie indeed.
But I insist on the fact that maggie should at no cost run real public
services.
Apart from that, I read that SVN was frequently broken wherever it is
provided. Installing it is one task, but maintaining is another. It would be
nice if Timothee can devote time to install it but it cannot work if he does
not have time to also maintain it on the long run.
-------------------------------------------------------

I'd propose to setup a Woody in a chroot'ed environment in our spare machine
(ie. Maggie), and have Timo install a SVN setup and try to write the
Savane/SVN backend (account creation, backup, etc).
If 1) it works, 2) we have a free IP to dedicate to this service (ports:
http{s}, ssh, ?), 3) we can buy a dedicated machine, it could be a new
official Savane service. I'm not firm on #3, we'll see the machine load by
then.
BTW, I've known Timo for a long time and trust him. He maintains ID Software's
GPL'ed level editor Gtk-Radiant as well as GNU/Linux ports of their (closed
source, yes:)) games. He's been closely involved with SVN and its community
for more than 2 years.
-------------------------------------------------------

any progress on that one?

I have noticed that some other sourceforge forks have started providing SVN
access. I don't know which codebase gna uses exactly.
http://developer.berlios.de/forum/forum.php?forum_id=4718
Anyway, to answer (partly) your questions:
- storage: GtkRadiant repository (https://zerowing.idsoftware.com:666/) has
4320 revisions, and uses 1.1Gb.
It's a fairly large repository, as it was converted from a CVS repository,
after 4 years of active developement, and is used to store binary media as
well as source code. SVN tends to be bigger though. Got an account of 120Mb ->
150Mb. Expect a size increase around 20%.
The storage is berkeley db, so it's a single large random access file.
- backup:
SVN provides a hot-backup.py script which can be used and extended. It does a
hotcopy to duplicate the repository. I run it croned daily. Only doing
hot-backup when the repository changes.
- CPU load. for regular usage, backups, viewsvn .. hard to estimate. The same
box ( P3 600Mhz ) we started GtkRadiant on CVS, we are still using with SVN.
SVN generally performs better for users for your server CPU cycles. Word on
the street is that it's less CPU intensive ( HD bound? ) + 'costs are
proportional to change size, not data size', which is not true for CVS.
- security / permissions etc.
the svnserve protocol doesn't offer much for permissions. It has an anonymous
mode (no write), and otherwise uses the permissions it is executed as. They
plan to improve on that, but the DAV way offers fine grained access already.
I can't say I'm a big fan of ssh for transport. It makes things fairly hard to
setup for windows users, which is my main problem with it. DAV over https,
with client certificates .. makes things about as secure as an ssh access
anyway.
- web interfaces to repository:
ViewCVS: Requires the python bindings. I gave up using it on GtkRadiant, as it
locks me up (
http://sourceforge.net/tracker/index.php?func=detail&aid=895294&group_id=18760&atid=118760
)
SVN::Web: uses the python bindings. Is more bare-bones than ViewSVN, but a
good alternative. That's what I'm running now, but it has scalability issues
on repos with a lot of branches.
Chora: requires php, word is Chora as experimental SVN support.
The web interfaces will likely be causing most of the load.
- cvsreport-like:
There are contributed scripts in the SVN repository. I have one with web URLs
which I can contribute. It's much easier to write that stuff with SVN than it
is with CVS.
-------------------------------------------------------

Let's try to detail a bit, we need :
- storage: what is the disk usage ratio between a CVS and SVN repository for
the same source tree ? What are bandwidth issues (lots of small scattered
files ? heavily random access ?)
- backup: svnadmin dump or hotcopy ? Need some insight (time, load,
compression).
- CPU cycles: difficult to estimate. Right now we only have 90 projects and
the CVS server is lightly loaded (0.1 average). What is the load ratio between
CVS and SVN for the same source tree and usage ?
- init: need to hook a 'svnadmin create' in the group creation backend.
- security: preferred transport will be SSH, user & group rights should work
as they are now. Expecting WebDAV when there is a dedicated server for SVN.
- helpers: ViewCVS 1.0-cvs supports SVN. Needs a cvsreport-alike.
Comments/addition welcome.
