[Ralf Baechle]

As a heads up, I've started playing with GIT as the replacement of CVS.
For information on the status of that conversion please see

  http://www.linux-mips.org/wiki/Git

The converted repositories are accessible at via rsync at

  rsync://ftp.linux-mips.org/git

And there gitweb, a web frontend to replace cvsweb available at:

  http://www.linux-mips.org/wiki/git

Browse around, let me know if you find anything that doesn't work as you
want it to.

For those with write permission into CVS, for now continue using CVS
as always.  For now the conversion is still only for testing and
figuring out all the kinks.

I assume the reason for choosing GIT was because the main line kernel
uses the same source management tool. No chance of using Subversion I
guess.

Subversion maybe better but not good enough to justify the pain of
switching, I think.

Btw, can subversion do a checkout in 10s?

Is SVN already distributed? In the past, the non-distributed reality
of CVS is what bought me a lot of trouble. And SVN isn't really
designed for distribution, is it?

I for one see SVN as a CVS rewrite with some design flaws fixed, but
it's for sure not what I actually want to use.

So I'm currently learning to use GIT. It's a bit strange when you
start using it (because usually I interact with git itself as well as
with eg. cogito), but I slowly get used to it :-)

SVN isn't, but SVK (which uses regular SVN) is.

I think for kernel development git is the way to go.

Which docs did you use to get yourself started? I'm also on the way
getting familiar with GIT, doing my very first steps. It would be nice
if we'd present what we know in Oldenburg (I already offered to do so,
Joey planed it for Saturday).

The tutorial.txt that comes with git is ok I guess; cvs-migration.txt is
helpful for CVS [1] experienced users.  And of course, my favorite search
engine.

Sounds like a plan.  And maybe present some of the other alternatives
to CVS as well?

Re: Git

[Dominic Sweetman]

Since I didn't understand it, I did some digging around.  I recorded
what I figured out so far (which may, of course, be deeply wrong) in a
wiki page

  http://www.linux-mips.org/wiki/WhatIsGit

Unless and until someone else comes up with a link to something better
like this - which I appreciate quite likely exists somewhere - perhaps
this will get amended by others and become useful.

Whenever you want to start a new thread of discussion, please do so
and don't simply press 'Reply' on some unrelated email and change the
subject line. Your patches don't correspond to the GIT discossen, so
please keep out out of it.

I'm not sure if it's worth it. Linus decided against all other SCMs. I
did use (for small test projects) monotone, darcs and arch. (I think
all other alternatives aren't.)

monotone
	Is quite nice'n'easy to use for CVS users, you'll have quite a
	fast start. The network sync protocol can be a bit lengthy at
	a time, but it works. It's acceptable in speed, but not
	exactly "fast". Written in C, code can easily be read and
	hacked.

darcs
	Is easy to use, too, and quite some helpful. Network
	operations are a bit slower than those of monotone, but the
	real point is that it's merging algorithms are awfully slow.
	Also, it's written in Haskell (and getting a working compiler
	isn't exactly trivial), so the code is hard to read (for a C
	person), mostly because Haskell's concept are so different
	(it's a function programming language, after all.)

arch
	Arch can do almost everything; it's network sync protocol is
	quite fast (can use several transports and will make use of
	caches). However, it's not exactly easy to use because of it's
	thousands of commands and it's project name conventions are,
	um, ugly. It has very good merging capabilities, but it's
	heavy use of local caches forces you to have loads of free HDD
	space.

CVS
	Um, we all know the problems, don't we?

SVN
	Not distributed, easy to use.  Though there's a different
	frontend with distribution capabilities. Personally, SVN feels
	like CVS with it's major conceptual problems fixed.

More SCM questions?

So my famous last words are:  I don't think it's worth really
presenting all the other alternatives (except probably reading down
the above text).

To get fixes/port updates/subsystem updates upstream to Linus, GIT is
the way[tm] to go, so we'd try to get familiar with it.

MfG, JBG

Nope. I've only used it's web frontend on http://www.kernel.org/hg/ .

Mercurial's author claims that it scales even better than git, esp. on
its network transfer. However, I'm not aware how it scales there right
now, since git got its "packs" implemented.

...which is a nice and actually working scheme, too. At least, it
doesn't require to learn working with a new SCM :-P  Though I think
it's a good idea.

Git has taken some ideas from Monotone.

In my tests at the beginning of the year darcs's performance was
undescribably low.  The speedup factor needed to make it useful for any
large project probably cannot be described in a floating point number.

Git is a huge diskspace consumer also unless repositories are converted.
For example, the Linux kernel repository from CVS did inflate itself to
over 4GB and over 340,000 files.  After packing I got that down to like
170MB.  Not bad compared to the some 770MB of RCS files it's using
currently and < 11s checkout from git can't be wrong either ;-)

And plenty of reports about database corruption that are not terribly old
so I'd feel uneasy to keep the crown jewels there.

The other accepted currency of the trade are still simple patches, see

This was related to the underlying berkeleydb, the switch to fsfs
fixed that. (SVN is used for several larger Debian projects like
its Xfree86/XOrg tree, it holds up quite well there.)

Btw, there's also SVK which implements a distributed system on top
of SVN. Some general comparision of the various SCMs:

Though monotone uses a (berkeley?) DB to store all objects...

Well, Arch *may* cache any tree version you check out. So take a
source tree and check-out some 15 tree versions, you may end up with a
really *hugh* cache. You're free to delete it, though...

ACK. But unless you've got the perfect Patch Queue Manager that'll
re-diff and re-send your patches automatically to Linus, you keep on
doing some manual work or at least starting your scripts ever and ever
again :)

Speaking of patch management, has anyone tried out Stacked GIT (aka 
StGIT, aka quilt on GIT) at http://www.procode.org/stgit/? It looks like 
it could be useful, and can be used in conjunction with other porcelain 
like Cogito.

No, not yet, mostly due to time reasons. But I second it sounds
useful.
