[git bash][ssh] unable to accessing a remote hg repo through ssh #428

Closed nanake closed 9 years ago

nanake commented 9 years ago

In Git-1.9.5-preview20150319, I can access remote hg repo.

Ake@SIGMATAUPI /D/dev/custume $ hg pull pulling from ssh://hg@bitbucket.org/nanake/custume Enter passphrase for key '/c/Users/Ake/.ssh/bitbucket/id_rsa': searching for changes no changes found

When I upgraded to Git-2.5.3-32-bit.

I can access to git repo.

Ake@sigmataupi MINGW32 /d/dev/sandbox (master) $ git pull Enter passphrase for key '/c/Users/Ake/.ssh/bitbucket/id_rsa': Already up-to-date.

I cannot access remote hg repo.

Ake@sigmataupi MINGW32 /d/dev/custume $ hg pull pulling from ssh://hg@bitbucket.org/nanake/custume remote: Permission denied (publickey). abort: no suitable response from remote hg!

Ake@sigmataupi MINGW32 /d/dev/custume $ hg in remote: Permission denied (publickey). abort: no suitable response from remote hg!

but I can ssh -t

Ake@sigmataupi MINGW32 /d/dev/custume $ ssh -T hg@bitbucket.org Enter passphrase for key '/c/Users/Ake/.ssh/bitbucket/id_rsa': logged in as nanake. ` You can use git or hg to connect to Bitbucket. Shell access is disabled.`

github:

Ake@sigmataupi MINGW32 /d/dev/custume $ ssh -T git@github.com Enter passphrase for key '/c/Users/Ake/.ssh/github/id_rsa': Hi nanake! You've successfully authenticated, but GitHub does not provide shell access.

:heart_eyes::heart_eyes: Please support access to hg repo via ssh again like git 1.9.5 :heart_eyes::heart_eyes:

I'm on windows 10. Install from installer. Options are:

  1. use git and optional unix tools from windows command prompt
  2. checkout as-is, commit unix style line endings

In your ~/.ssh/config, could you set LogLevel DEBUG3 for the BitBucket host?

dscho commented 9 years ago

Oh, I think I know what it is... It is Python not being able to handle the mintty console window. To verify, could you test both of the following two options?

  1. winpty hg pull
  2. reinstall with the "default Windows console" instead of the mintty one, then run hg pull
nanake commented 9 years ago
  1. winpty hg pull

$ winpty hg pull pulling from ssh://hg@bitbucket.org/nanake/custume remote: Permission denied (publickey). abort: no suitable response from remote hg!

  1. reinstall with the "default Windows console" instead of the mintty one, then run hg pull

It's the same as 1. remote: Permission denied (publickey). abort: no suitable response from remote hg!

In your ~/.ssh/config, could you set LogLevel DEBUG3 for the BitBucket host?

Nothing happened after running hg pull. I wait about 5 mins and have to terminate git bash. $ hg pull pulling from ssh://hg@bitbucket.org/nanake/custume

I tried to add LogLevel DEBUG3 to the other hosts and still can't run hg pull, hg in, hg out.

but I can git pull with LogLevel DEBUG3

Enter passphrase for key '/c/Users/Ake/.ssh/bitbucket/id_rsa':

I guess it is this line that is most helpful in identifying the problem. Unfortunately, the winpty invocation did not address this (which I hoped it would). But maybe you can still save your use case by setting SSH_ASKPASS:

export DISPLAY=needs-to-be-defined
export SSH_ASKPASS=/mingw64/libexec/git-core/git-gui--askpass

(You might need to invoke hg in </dev/null to force the GUI to pop up.)

Does that work for you?

The alternative would be of course to switch to MSys2 altogether and use its own Mercurial which is guaranteed to work fine.

That works for me. :smiley: :kissing_heart:

Thank you so much for fixing this. :satisfied:

I tried to apply the patch to etc/profile.d/env.sh on PortableGit-2.5.3 and can confirm it is fixed.
