[jira] [Updated] (SSHD-1143) Example for JGit
TransportConfigCallback with MINA
[ https://issues.apache.org/jira/browse/SSHD-1143?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Joern Guy Suess updated SSHD-1143:
----------------------------------
Description:
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].
Would it be possible to provide an example or some boilerplate for this case?

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?
