tests: Avoid sleep when causing a write error

2026-06-03T22:10:08Z

Cause a write error using a fifo and wait, rather than needing a sleep to wait for something to terminate. This is faster and avoids a potential test failure on a heavily loaded system. Using /dev/full would be simpler, but it is not portable enough (it tends not to be available in jails, even). Starting programs with stdout not open or only open for read/execute/search may have unexpected side effects. Reviewed by: ngie, des Differential Revision: https://reviews.freebsd.org/D57213

Improve reliability of stdout tests.

2024-11-14T19:41:47Z

If the test runner is under heavy load, the command we are testing may succeed in printing to stdout before the dummy receiver has terminated. Add a short delay to reduce the likelihood of this happening. MFC after: 1 week Sponsored by: Klara, Inc. Reviewed by: markj Differential Revision: https://reviews.freebsd.org/D47572

cmp: Check the status of stdout.

POSIX requires us to print an error message and exit non-zero if writing to stdout fails. This can only happen if sflag is unset. MFC after: 3 days Sponsored by: Klara, Inc. Reviewed by: markj Differential Revision: https://reviews.freebsd.org/D47020

Remove copyright strings ifdef'd out

2023-11-27T05:23:58Z

We've ifdef'd out the copyright strings for some time now. Go ahead and remove the ifdefs. Plus whatever other detritis was left over from other recent removals. These copyright strings are present in the comments and are largely from CSRG's attempt at adding their copyright to every binary file (which modern interpretations of the license doesn't require).
