Error: undefined local variable or method `stdin'

[chrispi68]

Hello,

starting svn2git with

sudo svn2git http://192.168.2.161:8080/svn/erpsystem/ --username transfer --verbose

results in this error message:

I am running Ubuntu 18.04

svn checkout http://192.168.2.161:8080/svn/erpsystem/ --username transfer

works without any problems.

Any ideas?

Best regards Christoph

Hello,

same probleme for me, ubuntu 18.04 ruby version is 2.5.0.

It worked for me 3-4 month ago on another computer but not anymore with fresh install. Perhaps ruby version is the cause ?

[xrobert35]

Dont really know what I have done but it seem to work.

I installed "rvm" ruby version manager I installed ruby 2.4.0 with rvm and set it to be the default

Then I changed "sudo svn2git" by "rvmsudo svn2git"

[jrbenito]

same here, if I am local to the machine svn2git works because it pops password prompt graphically. When I am remote, ssh, it does not accept password from the command line same as above.

[adrsr]

Hello, I've had the very same issue. The password prompt may be the problem. This works for me : https://github.com/nirvdrum/svn2git/issues/237

yes <password> | svn2git <url> --username <usr> --authors ~/authors

[belgoros]

@adrsr it fails for me when running as you suggested: yes <password> | svn2git svn+ssh://<svn-url> --username <username> --authors ~/authors.txt with the below error:

hello @belgoros

I'm afraid I can't help you. Maybe you can try with Debian OS. That's what I used for the migration.

Unfortunately, this project is no longer maintained and there are a lot of bugs.

[th0ger]

Hmmm, no longer maintained, but referenced in the official gitlab docs? https://docs.gitlab.com/ee/user/project/import/svn.html#cut-over-migration-with-svn2git

[th0ger]

Same error here.

For me it was a communication problem with svn2git and the git binary....

can you try (INSECURE, please check / remove your .gitconfig afterwards as it will include plain text passwords):

git config credential.helper store
git config --global user.name "your username"
git config --global user.password "your password"

then retry your svn2git command... everytime it fails it will tell you with what command it fails:

command failed:
git svn init --prefix=svn/ --username=**** --no-metadata --trunk=trunk --tags=tags --branches=branches https://*****

retry that command on the commandline to get more information from git itself... once i ironed out all the password requests from git .... svn2git worked without any problems...

hope it helps.

This problem seems to be related to missing optional (perl?) packages for git.

On Archlinux I can see the optional dependencies with this command: pacman -Si git

Then I just installed all of them: sudo pacman -S perl-libwww perl-term-readkey perl-mime-tools perl-net-smtp-ssl perl-authen-sasl perl-mediawiki-api perl-datetime-format-iso8601 perl-lwp-protocol-https perl-cgi python subversion org.freedesktop.secrets libsecret tk

After that it worked.

https://github.com/mazong1123/svn2gitnet

in case I forgot, this is a .net core version of the tool that @mazong made which does not suffer from this issue. switching to this adaptation solved it for me.

it has both fixed the "--password option not working" and the "stdin loop" issues

Some comments for people equally late to the git train who run into this when following the instructions in the main README:

• if you are on Debian or Ubuntu, install the package with apt-get instead of the gem [1], other distributions may have similar fixes
• if you are on the console, e.g. via ssh, attempting to provide the svn password and either (a) the --password option of svn2git does not work because git does not have a --password option (any more), or (b) entering a password gets you "No input requested." as a reply, do not waste time trying to get subversion to store the password for you. I could not get it to work, it seems that this feature has been removed in modern versions to some extend?! Instead, try to get a something graphical. I used xrdp and Remote Desktop to get a Terminal window, which then let svn pop-up a GNOME keyring window, which finally stored the password and svn2git began the conversion.
