When checking if the newly opened file is the same as the old one,
we need to fstat() the new file descriptor, not the old one again.

Use -F instead of -f in tail(1) examples2020-03-22T21:51:50ZMateusz Piotrowski0mp@FreeBSD.org2020-03-22T21:51:50Zurn:sha1:c0f2b64a8945fe4a217e8969c5c278a59f728a01
There is an example in tail(1) manual page explaining how to use tail(1) to
track the contents of /var/log/messages. The example uses the -f flag to
follow the file. The problem with the -f flag is that it cannot handle the
situation where /var/log/messages is rotated. Hence, use -F instead in the
example.

Leaf directories that have dependencies impacted
by options need a Makefile.depend.options file
to avoid churn in Makefile.depend
DIRDEPS for cases such as OPENSSL, TCP_WRAPPERS etc
can be set in local.dirdeps-options.mk
which can add to those set in Makefile.depend.options
See share/mk/dirdeps-options.mk

Fix tail -f in capability mode.2019-12-06T23:39:38ZMark Johnstonmarkj@FreeBSD.org2019-12-06T23:39:38Zurn:sha1:eee07d30a0b3ff6448ce3441b8808c5529a9505d
We were not adding CAP_EVENT to input file capabilities, so kevent()
always failed with ENOTCAPABLE. tail implements a fallback mode to
poll the file in this case, so the failure was not apparent.

tail: fix the checks if the file was rotated2019-06-09T22:55:21ZMariusz Zaborskioshogbo@FreeBSD.org2019-06-09T22:55:21Zurn:sha1:c851fce6d779e8340609d7e2364829c61cbcb1ef
The freopen(3) was replaced with fileargs_open(3) and fclose(3).
In the following function, we skip if the stream is standard in, so it is
safe to do so.
This also requires us to change the logic first to open the file and then
check its status. The stat(2) is disallowed in capability mode.
This commit unbrakes the -F option.
The bug was introduced in the r348708.
