Change subject: bootstrap: new implementation for apache-sshd usage ...................................................................... bootstrap: new implementation for apache-sshd usage Major changes: 1. Do not use temporary files for compression/decompression. 2. Do not use wget to pull large files, use ssh for all transfers. 3. One pass on files for digest, compress/decompress, send/receive. 4. Do not pull every 1 second for bytes/status. 5. Test for command status code. 6. File transfer using ssh and md5sum at same session, md5sum written to stderr. 7. Limit buffer size when reading remote output, so we won't exhaust all memory. 8. Do not echo back whole file content when sending file. 9. Consistent error, exception handling and debugging information. 10. More unit tests. Split between pure ssh implementation[1] and application logic[2]. Unit tests now have their own dedicated generic sshd[3], for proper work in embedded mode ssh apache-ssh-0.7.0 is required. Separate unit tests dedicated to OVirtSSH implementation, by default embedded apache-sshd is used, this can be overridden by setting java system properties, see[4]. As unit tests takes long time, use -Penable-ssh-tests to activate.
