[jira] [Created] (SSHD-1143) Example for JGit
TransportConfigCallback with MINA
Joern Guy Suess created SSHD-1143:
-------------------------------------
Summary: Example for JGit TransportConfigCallback with MINA
Key: SSHD-1143
URL: https://issues.apache.org/jira/browse/SSHD-1143
Project: MINA SSHD
Issue Type: Improvement
Affects Versions: 2.5.1
Reporter: Joern Guy Suess
JGit used to rely on JSch as its transport provider, but changed because JSch does not accept certain keys, including some OpenSSH ones.
If you are using a passphrase-encrypted key with JGit, the recommended approach with JSch used to be [to override a configuration callback, as shown in this blog article](https://blog.sebastian-daschner.com/entries/access-git-from-java).
The alternative is to [set a shared session factory](https://stackoverflow.com/questions/12502452/how-do-you-set-the-configuration-for-jschconfigsessionfactory-for-jgit-so-that-p#answer-15290861) and this [also what the Apache MINA team recommends with a pointer to the cost of creating sessions on demand](https://github.com/apache/mina-sshd/blob/master/docs/git.md#user-content-client-side).
However, my issue with this is that it sets a specific provider for the whole system scope. Consequently, I would like to implement [`TransportConfigCallback`](https://archive.eclipse.org/jgit/docs/jgit-2.0.0.201206130900-r/apidocs/org/eclipse/jgit/api/TransportConfigCallback.html). Ultimately, this requires to adapt [`SshSessionFactory`](https://archive.eclipse.org/jgit/docs/jgit-2.0.0.201206130900-r/apidocs/org/eclipse/jgit/transport/SshSessionFactory.html) to MINA's session initialization code and produce a [`RemoteSession`](https://archive.eclipse.org/jgit/docs/jgit-2.0.0.201206130900-r/apidocs/org/eclipse/jgit/transport/RemoteSession.html).
Has anyone done this or seen any boilerplate code?
