Subject: [PATCH 2/2] tests: xz: Use 16M block size when preparing disk for xz
|
||
plugin test.

In a recent commit guestfish changed the default size for disk images
|
||
prepared using the -N parameter from 100M to 1G:
|
||
|
||
https://github.com/libguestfs/libguestfs/commit/adc23829e4b128562c2c29d984654528bd259644
|
||
|
||
For the xz plugin test we prepared a disk image using guestfish and
|
||
then xz-compressing the output, but we did not take our own advice and
|
||
use the --block-size parameter to limit the xz block size. Because of
|
||
the increased size of the disk as a whole, this pushed the block size
|
||
beyond the limit that the xz plugin can handle, and the test would
|
||
fail with:
|
||
|
||
nbdkit: error: /var/tmp/nbdkit-1.3.1/tests/disk.xz: xz file largest block is bigger than maxblock
|
||
Either recompress the xz file with smaller blocks (see nbdkit-xz-plugin(1))
|
||
or make maxblock parameter bigger.
|
||
maxblock = 536870912 (bytes)
|
||
largest block in xz file = 1073741824 (bytes)
|
||
|
||
Simple fix by adding the --block-size parameter.
|
||
|
||
Note that to see the effect of this change you will need to ‘make
|
||
maintainer-clean’ or remove the files ‘tests/disk’ and ‘tests/disk.xz’
|
||
by hand.
