public class JGitClientSession
extends org.apache.sshd.client.session.ClientSessionImpl

A ClientSession that can be associated with the HostConfigEntry the session was created for. The JGitSshClient creates such sessions and sets this association.

Also provides for associating a JGit CredentialsProvider with a session.

Field Detail

DEFAULT_MAX_IDENTIFICATION_SIZE

private static final int DEFAULT_MAX_IDENTIFICATION_SIZE

Default setting for the maximum number of bytes to read in the initial protocol version exchange. 64kb is what OpenSSH < 8.0 read; OpenSSH 8.0 changed it to 8Mb, but that seems excessive for the purpose stated in RFC 4253. The Apache MINA sshd default in CoreModuleProperties.MAX_IDENTIFICATION_SIZE is 16kb.

                      throws java.lang.Exception

As long as we're still setting up the proxy connection, diverts messages to the StatefulProxyConnector.

Overrides:

messageReceived in class org.apache.sshd.common.session.helpers.AbstractSession

Throws:

java.lang.Exception

resolveAvailableSignaturesProposal

protected java.lang.String resolveAvailableSignaturesProposal(org.apache.sshd.common.FactoryManager manager)

Overrides:

removeFromList

private void removeFromList(java.util.Set<java.lang.String> current,
                            java.lang.String key,
                            java.lang.String patterns)

Reads the RFC 4253, section 4.2 protocol version identification. The Apache MINA sshd default implementation checks for NUL bytes also in any preceding lines, whereas RFC 4253 requires such a check only for the actual identification string starting with "SSH-". Likewise, the 255 character limit exists only for the identification string, not for the preceding lines. CR-LF handling is also relaxed.

Overrides:

doReadIdentification in class org.apache.sshd.common.session.helpers.SessionHelper

Parameters:

buffer - to read from

server - whether we're an SSH server (should always be false)

Returns:

the lines read, with the server identification line last, or null if no identification line was found and more bytes are needed

Throws:

java.io.StreamCorruptedException - if the identification is malformed
