Hello friends I have a local cvs repository. i want to migrate Git from CVS
repository by using cvs2svn/cvs2git tool.i am using Cygwin shell for run
commands. and i am successfully able to execute and get the output . But i
want to ignore Cygwin and want to run all commands on CMD windows. for that
i installed all required software in my system. when run following command i
get below errors.


command is= python ./cvs2git --blobfile=D:\CVSDump\git-help2-blob.dat
--dumpfile=D:\CVSDump\git-help2-dump.dat D:\CVSRepository \Help
--username=cvs2git --retain-conflicting-attic-files

want to ignore Cygwin and want to run all commands on CMD windows. for that

[...]
ERROR: The command 'cvs -Q -f -d :local:D:\\CVSRepository co -r1.1 -p -kb
Help/.classpath' failed with exit status=0
and the following output: cvs checkout: cwd=D:\cvs2svn-2.4.0
,current=D:\cvs2svn-2.4.0

The error message above tells what happened. cvs2git tried to run the
command

cvs -Q -f -d :local:D:\\CVSRepository co -r1.1 -p -kb Help/.classpath

The command exited with exit status 0 (i.e., no error) but it wrote
output to stderr. Since such output is not expected, cvs2git considers
it an error. The output was

cvs checkout: cwd=D:\cvs2svn-2.4.0 ,current=D:\cvs2svn-2.4.0

My guess is that the "cvs" command on your system is a batch file that
is generating this extra output for debugging purposes. If so, please
change the batch script, or tell cvs2git to run cvs via a different
command that doesn't generate output by using the --cvs=PATH option.

@Micheal Thanks for your quick replay. really i appreciate you. i simple
install TortoiseCVS for windows. i am not using any cvs batch file. can you
tell me why system run below command

cvs -Q -f -d :local:D:\\CVSRepository co -r1.1 -p -kb Help/.classpath

see CVSRepository is my cvs repository directory , Help is cvs module and
.classpath is one file which is present inside the Help module. i hope i
give may be wrong path. i just describe which command i run

python ./cvs2git --blobfile=D:\CVSDump\git-help2-blob.dat
--dumpfile=D:\CVSDump\git-help2-dump.dat D:\CVSRepository \Help
--username=cvs2git --retain-conflicting-attic-files

see CVSDump is a folder where i want to store both blob and dump files.
D:\CVSRepository \Help is my local cvs module name

I run this command within cvs2svn folder which I downloaded.
i not useing any --use-cvs or --use-rcs and not install any software for
same.
please tell me is there any problem with this command.

The cvs2git script has to get the contents of file revisions out of CVS.
By default, the way it does so is to use the "cvs" program itself like
the command line above. Probably if you run the same command by hand in
the command line, you will get the same output to stderr.

--use-cvs is the default. The other alternatives are --use-rcs
(requires software from RCS) and --use-external-blob-generator, which
doesn't require any external software.

The problem is not with how you are invoking cvs2git but rather how CVS
is installed on your system. It is generating extraneous output, and
that is bothering cvs2git.

If all else fails, maybe you could wrap cvs in a batch file that
discards stderr explicitly, then use the --cvs option to tell cvs2git
where to find your batch file. I'm not a Windows user so I can't help
you with the details.

Thanks Micheal for your help. i can not find where i made the mistake .Even i
reinstall TortoiseCVS and keep in separate batch file. still i get the same
error. but i strange that when i run the same command in Cygwin in same
system , pass 4 (FilterSymbolsPass) take few second and after that execute
successfully, but in command line it throws error with status 0.

I have installed following tools on my machine.
1) cvs2svn-2.4.0
2) python-2.7
3)CVS-1.12.5
4)git-1.7.9

cvs works as a local CVS repository. My question is there any other way
through which i can generate blob and dump files from CVS repository?

You can try --use-external-blob-generator.

I think you've typed the source URL wrong. I think you need something like

rsync -av rsync://***@cvs.example.org/CVSRepository/path
/cygdrive/E/LocalCVSDump

Of course, this will only work if the host at cvs.example.org has an
rsync server running and you have permissions to access it.

I have no idea. It is not a standard command, so you will probably have
to download and build it yourself.
