# Description: When creating multivolume archives, the bufmap code in
|
|
# buffer.c implicitly assumed that the members are stored in the archive
|
|
# in a contiguous fashion, ignoring the member (and eventual extended) headers
|
|
# between them. This worked until the member header happened to be at
|
|
# the very beginning of the volume, in which case its length was included in
|
|
# the calculation of the stored size and size left to store. Due to this,
|
|
# the GNUFileParts extended header contained invalid GNU.volume.offset value,
|
|
# and the resulting archive failed to extract properly. The bug affected
|
|
# versions of tar up to 1.29.90 (commit da8d0659a6).
|
|
#
|
|
# This test case also checks that GNUFileParts headers are not displayed in
|
|
# verbose mode.
