Prompted by the continuous integration build failure at:
http://hydra.nixos.org/build/277485
* tests/misc/timeout: Set all expected timeouts to 1s and all
unexpected timeouts to 10s. In this way, tests normally proceed
quickly but may delay up to 10s before reporting failures.
* tests/ls/infloop: Likewise.
* tests/tail-2/pid: Likewise.
* tests/tail-2/pipe-f: Likewise.
* tests/tail-2/wait: Likewise.
* tests/dd/skip-seek-past-dev: Likewise.

Use this command:
git ls-files | grep -v COPYING \
| xargs env UPDATE_COPYRIGHT_USE_INTERVALS=1 \
build-aux/update-copyright
|
|
Run this command to remove the factored-out "fail=0" lines.
perl -ni -e '/^fail=0$/ or print' $(g grep -l '^fail=0$')
* tests/test-lib.sh: Initialize fail=0 here, not in 300+ scripts.
* tests/...: nearly all bourne shell scripts
Suggested by Eric Blake.

Following are the before and after operations for seekable files,
for the various erroneous offsets handled by this patch:
skip beyond end of file
before: immediately exit(0);
after : immediately printf("cannot skip to specified offset"); exit(0);
skip > max file size
before: read whole file and exit(0);
after : immediately printf("cannot skip: Invalid argument"); exit(1);
seek > max file size
before: immediately printf("truncate error: EFBIG"); exit(1);
after : immediately printf("truncate error: EFBIG"); exit(1);
skip > OFF_T_MAX
before: read whole device/file and exit(0);
after : immediately printf("cannot skip:"); exit(1);
seek > OFF_T_MAX
before: immediately printf("truncate error: offset too large"); exit(1);
after : immediately printf("truncate error: offset too large"); exit(1);
skip > device size
before: read whole device and exit(0);
after : immediately printf("cannot skip: Invalid argument"); exit(1);
seek > device size
before: read whole device and printf("write error: ENOSPC"); exit(1);
after : immediately printf("cannot seek: Invalid argument"); exit(1);
* NEWS: Summarize this change in behavior.
* src/dd.c (skip): Add error checking for large seek/skip offsets on
seekable files, rather than deferring to using read() to advance offset.
(dd_copy): Print a warning if skip past EOF, as per FIXME comment.
* test/Makefile.am: Add 2 new tests.
* tests/dd/seek-skip-past-file: Add tests for first 3 cases above.
* tests/dd/seek-skip-past-dev: Add root only test for last case above.
