* tests/cat/splice.sh: Ensure splice is called multiple times
before we check specific invocation counts.
On Linux kernel 5.10 for example, splice from /dev/zero
returns EINVAL.
cat: use splice if operating on pipes or if copy_file_range fails2026-04-07T04:57:07ZCollin Funkcollin.funk1@gmail.com2026-03-29T23:13:01Zurn:sha1:457f88513a128ce91160c4a60f821cc1612204be
On a AMD Ryzen 7 3700X system:
$ timeout 10 taskset 1 ./src/cat-prev /dev/zero \
| taskset 2 pv -r > /dev/null
[1.67GiB/s]
$ timeout 10 taskset 1 ./src/cat /dev/zero \
| taskset 2 pv -r > /dev/null
[9.03GiB/s]
On a Power10 system:
$ taskset 1 ./src/yes | timeout 10 taskset 2 ./src/cat-prev \
| taskset 3 pv -r > /dev/null
[12.9GiB/s]
$ taskset 1 ./src/yes | timeout 10 taskset 2 ./src/cat \
| taskset 3 pv -r > /dev/null
[81.8GiB/s]

Update to latest gnulib with new copyright year.
Run "make update-copyright" and then...
* gnulib: Update included in this commit as copyright years
are the only change from the previous gnulib commit.
* tests/init.sh: Sync with gnulib to pick up copyright year.
* bootstrap: Likewise.
* tests/sample-test: Adjust to use the single most recent year.
cat: don’t trust st_size on /proc files2024-04-06T22:18:27ZPaul Eggerteggert@cs.ucla.edu2024-04-06T22:13:23Zurn:sha1:225cb8d7473eadb481a4884e929bf23589d4bd82
* src/cat.c (main):
Improve test for when copying will exhaust the output device.
Do not rely on st_size, which is unreliable in /proc.
Use lseek instead; this is good enough here.
* tests/cat/cat-self.sh: Test the relaxation of the heuristic
for self-copying.
