# Ensure that using `cp --preserve=link' to copy hard-linked arguments
|
|
# onto existing destinations works, even when one of the link operations fails.
|
|
# This bug was fixed in coreutils-4.5.9.
|
|
# To exercise this bug is non-trivial:
|
|
# Set-up requires at least three hard-linked files. In copying them,
|
|
# while preserving links, the initial copy must succeed, the attempt
|
|
# to create the second file via `link' must fail, and the final `link'
|
|
# (to create the third) must succeed. Before the corresponding fix,
|
|
# the first and third destination files would not be linked.
|
|
#
|
|
# Note that this is nominally a test of `cp', yet it is in the tests/mv
|
|
# directory, because it requires use of the --preserve=link option that
|
|
# mv enables by default.
