fts_read: Handle error from a NULL return better.

2020-12-08T23:38:26Z

This is addressing cases such as fts_read(3) encountering an [EIO] from fchdir(2) when FTS_NOCHDIR is not set. That would otherwise be seen as a successful traversal in some of these cases while silently discarding expected work. As noted in r264201, fts_read() does not set errno to 0 on a successful EOF so it needs to be set before calling it. Otherwise we might see a random error from one of the iterations. gzip is ignoring most errors and could be improved separately.

cp: add some basic tests

2020-09-23T03:01:14Z

There are some tests available in the NetBSD test suite, but we don't currently pass all of those; further investigation will go into that. For now, just add a basic test as well as a test that copies from /dev/null to a file. The /dev/null test confirms that the file gets created if it's empty, then that it truncates the file if it's non-empty. This matches some usage that was previously employed in the build and was replaced in r366042 by a simpler shell construct. I will also plan on coming back to expand these in due time.

cp: fall back to read/write if copy_file_range fails

2020-09-11T20:49:36Z

Even though copy_file_range has a file-system agnostic version, it still fails on devfs (perhaps because the file descriptor is non-seekable?) In that case, fallback to old-fashioned read/write.

cp: use copy_file_range(2)

2020-09-10T02:48:55Z

This has three advantages over write(2)/read(2): * Fewer context switches and data copies * Mostly preserves a file's sparseness * On some file systems (currently NFS 4.2) the file system will perform the copy in an especially efficient way.

General further adoption of SPDX licensing ID tags.

2017-11-20T19:49:47Z

Mainly focus on files that use BSD 3-Clause license. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point.

Renumber copyright clause 4

2017-02-28T23:42:47Z

Renumber cluase 4 to 3, per what everybody else did when BSD granted them permission to remove clause 3. My insistance on keeping the same numbering for legal reasons is too pedantic, so give up on that point. Submitted by: Jan Schaumann Pull Request: https://github.com/freebsd/freebsd/pull/96

Explicitly add unmarked bin/ binaries to the runtime package.

Note: tcsh(1) has a MK_TCSH=no test, so this should be a separate package, which requires pre-install/post-install scripts, to be added later. Sponsored by: The FreeBSD Foundation
