This action instructs tar to pause until given signal is delivered. The newer genfile tool uses this action for communication between genfile and tar in exec mode. This eliminates race conitions and speeds up the tests based on exec mode. * doc/tar.texi: Document changes. * paxutils: Upgrade. * src/checkpoint.c: Implement the wait action. * src/common.h (decode_signal): New proto. * src/tar.c (decode_signal): New function. (set_stat_signal): Rewrite. * tests/dirrem01.at: Adjust genfile and tar command line arguments to use the new feature. * tests/dirrem02.at: Likewise. * tests/filerem01.at: Likewise. * tests/filerem02.at: Likewise. * tests/grow.at: Likewise. * tests/sptrcreat.at: Likewise. * tests/sptrdiff00.at: Likewise. * tests/sptrdiff01.at: Likewise. * tests/truncate.at: Likewise.

# Description: when a file in a deep directory disappeared during creation
|
|
# of incremental dump, tar v. <1.23 would exit with TAREXIT_FAILURE (2).
|
|
# However, such events are quite common and don't necessarily constitute
|
|
# an error. Exiting with code 2 in such cases makes it impossible to
|
|
# distinguish serious errors from benign ones.
|
|
#
|
|
# Starting from tar 1.22.90, tar exits with TAREXIT_DIFFERS (1)
|
|
# instead.
