* Add O_DIRECT flag to DD for cache bypassRichard Scheffenegger2020-06-044-4/+17
| | | | | | | | | | | | | | | FreeBSD DD utility has not had support for the O_DIRECT flag, which is useful to bypass local caching, e.g. for unconditionally issuing NFS IO requests during testing.

* Add iflag=fullblock to ddMatt Macy2019-09-304-21/+76
| | | | | | | | | | | | | | | | | | | | Normally, count=n means read(2) will be called n times on the input to dd. If the read() returns short, as may happen when reading from a pipe, fewer bytes will be copied from the input. With conv=sync the buffer is padded with zeros to fill the rest of the block. iflag=fullblock causes dd to continue reading until the block is full, so that count=n means n full blocks are copied. This flag is compatible with illumos and GNU dd and is used in the ZFS test suite. Submitted by: Ryan Moeller Reviewed by: manpages, mmacy@ MFC after: 1 week Sponsored by: iXsystems, Inc.

* dd(1): Correct padding in status=progressKyle Evans2018-09-131-3/+3
| | | | | | | | | | | | | | | | | | Output padding is specified via outlen, which is set using the return value of fprintf. Because it's printing that padding plus a trailing byte, it grows by one each iteration rather than reflecting actual length. Additionally, iec was sized improperly for scaling up similarly to si. Fixing this revealed that the humanize_number(3) call to populate persec was using the wrong width.

This ensures that namespacing is kept with FILES appropriately, and that this shouldn't need to be repeated if the namespace changes -- only the definition of PACKAGE needs to be changed - Allow PACKAGE to be overridden by callers instead of forcing it to always be `tests`. In the event we get to the point where things can be split up enough in the base system, it would make more sense to group the tests with the blocks they're a part of, e.g. byacc with byacc-tests, etc - Remove PACKAGE definitions where possible, i.e. where FILES wasn't used previously. - Remove unnecessary TESTSPACKAGE definitions; this has been elided into bsd.tests.mk - Remove unnecessary BINDIRs used previously with ${PACKAGE}FILES; ${PACKAGE}FILESDIR is now automatically defined in bsd.test.mk. - Fix installation of files under data/ subdirectories in lib/libc/tests/hash and lib/libc/tests/net/getaddrinfo - Remove unnecessary .include <bsd.own.mk>s (some opportunistic cleanup) Document the proposed changes in share/examples/tests/tests/... via examples so it's clear that ${PACKAGES}FILES is the suggested way forward in terms of replacing FILES. share/mk/bsd.README didn't seem like the appropriate method of communicating that info.
