- Generate testdisks via losetup
- When using local disk images BLK_PROXY_ADDR = ("files:","datatab.txt")
use json structure inside datatab.txt.
- To enable disk images bigger than 2TB split up a disk into 1 TB
chunks. The disk is specified as an array of chunks.
- Improve the server protocol:
Send data in chunks of 256kB. Send with packet prefixes and handle error:
'n' : next datachunk < 256kB
'e' : error occured
'l' : last chunk transmitted
- supply a testcase for file/server based run of py-zfs-rescue:
test/test_files.sh
test/test_server.sh

- Before the generated cache was linear instead of hirarchical, which resulted in false lookups on large trees. Create a cache tree instead. - Add verbosity option
- add -C option to default to childset archivation - read bonus attributes via funtions This is the last part of the patchseries: the files that are created inside the zfs images test/disk[0-3].bin via test/gen_disks.sh are extracted again into rescue/ds_<ds_num>.tar when running 'cd test; make runfiles' and 'cd test; make runserver'

With this patchset the files that are created via test/gen_disks.sh inside
a zfs raid-z1 image can be extraced again. This is done with testcase
test/test_files.sh and test/test_server.sh
