[BUG?] fail to svn clone debian's kernel repository

[Uwe Kleine-König]

Hello,

using git v1.6.3.1 from Debian I fail to successfully run

	git svn clone svn://svn.debian.org/kernel/dists/trunk/linux-2.6

It runs for some time and then ends in:

	...

Is someone wants to take a look, the repo is browsable at

I debugged this a bit by adding a print just before line 4388.  There we
have:

	rev_a=4090
	rev_b=4095
	path=""
	full_url=svn://svn.debian.org/kernel/dists/sid/kernel/linux-2.6
	old_url=svn://svn.debian.org/kernel/dists/sid/kernel/linux-2.6

Mmh, these are really heavy commits it seems.  The commitlog suggests
that trunk was moved there, and websvn dies with ENOMEM when trying to
show the diff.

I will try to start cloning at a later revision.

Best regards
Uwe

I have run into a similar problem, both with Git 1.7.0 as well as with
Git via Git.

Has anybody been able to work around this?
Is anybody working on a fix?

Thanks,



Sebastian

I've stopped cloning at r10252 with current next version. I didn't
notice any problem.

Does the tests pass for you ?

  $ cd t
  $ make

I've been working with another repository.

My case is reproducable as following:
=======================================================
ABS_SVN_SOURCE="$PWD/portage-anon-svn-repo-dump/"
rsync -r rsync://anonvcs.gentoo.org/vcs-public-svnroot/portage/ \
  "${ABS_SVN_SOURCE}"
mkdir portage-git
cd portage-git
git svn init file://"${ABS_SVN_SOURCE}" \
  --trunk=trunk --tags=NOTAGS --branches=NOBRANCHES
git svn fetch -r1:1890
git config --remove-section 'svn-remote.svn'
git svn init file://"${ABS_SVN_SOURCE}" \
  --trunk=main/trunk --tags=main/tags --branches=main/branches
git svn fetch -r1891:HEAD
=======================================================

The last command the fails with:
=======================================================
Found possible branch point:
file:///home/sping/__playground/portage-git-playground/portage-anon-svn-repo-dump/main/trunk

While arguably[*] a bug, you can work around it by simply not removing
the previous trunk from git-svn's 'fetch' lines.  I.e., the following
config works for me after r1890:

[svn-remote "svn"]
	url = file:///.../portage-anon-svn-repo-dump
	fetch = main/trunk:refs/remotes/trunk2
	branches = main/branches/*:refs/remotes/branches/*
	tags = main/tags/*:refs/remotes/tags/*
	fetch = trunk:refs/remotes/trunk

You can later use update-ref (or even just mv) to rename trunk2 to
trunk.

You may also want to place the cutoff in the above commands at
1889/1890 instead, since r1890 is the one that does the move.
Combining this fix with the above config results in correct
"continuous" history of trunk, whereas merely using the config above
results in a disconnect at the move.


[*] SVN also fails if you check out trunk@1889 and attempt to 'svn update' it

Thanks for your time to look into that!

After applying your ideas (which seem to work well) I end up with:
==================================================================
git svn init file://"${ABS_SVN_SOURCE}"
git config svn-remote.svn.fetch 'trunk:refs/remotes/trunk@1889'
git svn fetch -r1:1889
git svn init file://"${ABS_SVN_SOURCE}" \
  --trunk=main/trunk
git config svn-remote.svn.tags 'main/tags/*:refs/tags/*'
git config svn-remote.svn.branches 'main/branches/*:refs/heads/*'
git svn fetch -r1890:HEAD
==================================================================

.git/config holds:
==================================================================
[..]
[svn-remote "svn"]
        url = file:///[..]/portage-anon-svn-repo-dump
        fetch = trunk:refs/remotes/trunk@1889
        fetch = main/trunk:refs/remotes/trunk
        tags = main/tags/*:refs/tags/*
        branches = main/branches/*:refs/heads/*
==================================================================

Thought I'd paste that if anybody else is interested.
