time(3): Refine history in the manual page

2022-04-22T14:36:36Z

The time() system call first appeared in Version 1 AT&T UNIX. Through the Version 3 AT&T UNIX, it returned 60 Hz ticks since an epoch that changed occasionally, because it was a 32-bit value that overflowed in a little over 2 years. In Version 4 AT&T UNIX the granularity of the return value was reduced to whole seconds, delaying the aforementioned overflow until 2038. Version 7 AT&T UNIX introduced the ftime() system call, which returned time at a millisecond level, though retained the gtime() system call (exposed as time() in userland). time() could have been implemented as a wrapper around ftime(), but that wasn't done. 4.1cBSD implemented a higher-precision time function gettimeofday() to replace ftime() and reimplemented time() in terms of that. Since FreeBSD 9 the implementation of time() uses clock_gettime(CLOCK_SECOND) instead of gettimeofday() for performance reasons. With most valuable input from Warner (imp@).

libarchive: fix zstd compression support

2022-04-10T23:52:50Z

The commit 833a452e9 introduced a change that detached the zstd compression (not decompression) support from base build.

bectl: push space-in-name check down into libbe

2022-04-06T14:32:51Z

This check was previously in `create` only, not applying to renames. It should really be applied at the libbe level, so that we can avoid writing about this restriction over and over again. While we're here: `bectl rename` always succeeds, even when it doesn't. Start returning the error.

libbe: fix be_mounted_at() with props after bootonce

2022-04-06T14:32:44Z

propinfo.bootonce was filled with garbage, leading to a segfault later during prop building. Initialize it to NULL. Approved by: re (gjb) (cherry picked from commit d155d8e138563c0b39c658684e6a4fe6e2e36f8a) (cherry picked from commit 6ce8e35cead46048d9ae3c1dabafe1ef4ed26f97)

libbe: pull props for the correct dataset in be_mounted_at()

2022-04-06T14:32:31Z

The props feature to this API was added as a "just in case", with no planned consumer. It turns out that it was implemented incorrectly, tapping out props for the BE root (BE's parent) rather than the BE itself in all cases. Fetch properties for the dataset that's actually mounted at the queried path.
