git-cvsimport problem

[Alenoosh Baghumian]

Hi

I want to import a remote cvs repository to git , here's what I do :

$ mkdir git-test
$ chmod 775 git-test/
$ chmod +s git-test/
$ chmod +t git-test/
$ cd git-test
git-test$ git-cvsimport -k -i -d 
:pserver:anonymous@lib-pkp.lib.sfu.ca:/cvs -C myproj ojs2 -v

the output is the following :

Initialized empty Git repository in /home/tux/git-test/myproj/.git/
Running cvsps...

.

git-cvsimport: fatal: cvsps reported error

and every time I run this , it stops at the same point and gives that error.

Do you have any idea ?

Thanks in advance ...

This is typically caused by the inability of cvsps to handle complicated
CVS repositories or by corruption in your CVS repository.

If you are doing a one-time conversion, try using cvs2git/cvs2svn [1].
It is capable of handling more complicated CVS repositories.

Even if you need incremental conversion, you might want to try cvs2git
anyway, as it might give you a better error message if your CVS
repository is corrupt in some way.

git-cvsimport problem

Hi all

I run git-cvsimport in verbose mode and I see "* UNKNOWN LINE * 
Branches:" many times during execution , will that cause any problem ?
And my repository doesn't include any branches ? so why do I see this 
message ?

Thanks in advance .

You must be using the beta version of cvsps, cvsps-2.2b1

,---- From the CHANGELOG:
| 
| 2.2b1
| - add a new line item in the PatchSet output which indicates which 
|   branches fork off from after this PatchSet.  This is actually
|   the only way to correctly indicate the branching.  The 'Ancestor
|   Branch' thing is actually broken by design, and is now deprecated.
`----

git-cvsimport uses the -A ancestor mechanism (after patching cvsps-2.1
for some corner cases), this ignores the Branches line.

I'd be interested in knowing the git-cvsimport authors' opinion on
reworking it to use the Branches mechanism.

git-cvsimport problem

[Grzegorz Kulewski]

Hi,

I think I hit some problem in git-cvsimport or maybe cvsps or maybe (but 
unprobable) in network communication.

I am trying to do:

git-cvsimport -d :pserver:cvs@cvs.rulez.pl:/home/cvsroot -C lms -i -k -u 
-m -v lms

and it looks like it hangs in the middle with message:

cvs [rlog aborted]: unexpected '\x0' reading revision number in RCS file 
/home/cvsroot/lms/templates/noaccess.html,v

and to my understanding does not do anything usefull next. Nothing is 
imported (there is only nearly empty .git tree). I have to press CTRL-C to 
stop it.

strace:
[pid 30796] read(3, "---------------------\nM revision"..., 4096) = 2068
[pid 30796] read(3, "M date: 2003/06/20 21:07:56;  au"..., 4096) = 1448
[pid 30796] read(3, ".19\nM date: 2003/05/26 21:05:47;"..., 4096) = 1448
[pid 30796] read(3, " revision 1.15.2.3\nM date: 2003/"..., 4096) = 1276
[pid 30796] write(2, "cvs [rlog aborted]: unexpected \'"..., 117cvs [rlog 
aborted]: unexpected '\x0' reading revision number in RCS file 
/home/cvsroot/lms/templates/noaccess.html,v
) = 117
[pid 30796] read(3,       <-- hangs on that read

I am using:

What is going on?

Looks like a cvsps issue. From ps, grab the whole commandine that is
used for the cvsps invocation and try to run it manually. cvsps has
some debugging flags, I would try adding -x -v to see more output, and
perhaps try with --no-cvs-direct

The other thing affecting you is the version of the remote cvs server.

cheers,

Are you sure that CVS archive isn't corrupted? That sounds like an 
internal CVS error to me. Doing a "git cvsimport" will obviously get every 
single version of every single file, so it will inevitably also hit errors 
that you migt not hit with a regular "cvs co" (which will only get the 
current version).

There's bound to be some "fsck for CVS" (since people edit files by hand, 
and mistakes must happen), but I have no idea.

That said, it's not like we haven't had our share of cvsps issues and 
other things, so who knows..

Do "git log origin" to see what has been imported. If a cvsimport is 
broken in the middle, you'll not get any checked-out state, and your HEAD 
won't point to anything, but the "origin" branch has been created and 
contains whatever has been imported so far.
