- Replace "wtmp" with "utx.log" because last(1) no longer reads wtmp.
- A real filename is now shown in an output report when "-f file" is specified.

Remove stale references to utmp(5) and its corresponding filenames.

I removed utmp and its manpage, but not other manpages referring to it.

Make last(1) display the full log file.

I must have misread when I ported the original last(1) source code.
Instead of only processing the last 1024 entries, it reads them in in
chucks of 1024 entries at a time.

Unfortunately we cannot walk through the log file in reverse order,
which means we have to allocate a piece of memory to hold all the
entries. Call realloc() for each 128 entries we read.

Port last(1) to use utmpx.

Basically there are three major things I changed about last(1):

- It should use ut_type instead of determining by hand what type of
record was given.
- It should now keep track of ut_id's instead of TTYs. This means the
ttylist has been renamed to the idlist, storing all the ut_id's it has
processed until the next reboot.
- I've removed the signal handler. Because our wtmp is rotated so often,
it makes little sense. Even on a simple piece of hardware it should be
capable of grinding through megabytes of logs in a second.

Build usr.bin/ with WARNS=6 by default.

Also add some missing $FreeBSD$ to keep svn happy.

Oops, unbreak the -d and -<n> options. The `snapfound' variable

Split up the big wtmp() function to avoid long lines and code

Remove leaf node WARNS?=2 (that mainly I added). This should

I've been meaning to do this for a while. Add an underscore to the
time_to_xxx() and xxx_to_time() functions. e.g. _time_to_xxx()
instead of time_to_xxx(), to make it more obvious that these are
stopgap functions & placemarkers and not meant to create a defacto
standard. They will eventually be replaced when a real standard
comes out of committee.

localtime() was being called on an int pointer (due to recent

The last(1) choked if there were two successive "login" marks
found in wtmp(5) for the same TTY without in-between "logout"
mark.

This may be demonstrated by executing login(1), logging in and
out, and watching the last(1) output on this TTY:

: # last -tv7 -w
: ru ttyv7 Mon May 28 12:46 - 12:46 (00:00:01)
: ru ttyv7 Mon May 28 12:45 still logged in

The fix merely takes the second "login" mark as the "logout" for
the first "login" mark, if there were no "logout" mark in-between.
This restores the behavior of last.c,v 1.2:

: # last -tv7 -w
: ru ttyv7 Mon May 28 12:46 - 12:46 (00:00:01)
: ru ttyv7 Mon May 28 12:45 - 12:46 (00:00:25)

Fixed a bug that caused last(1) to be extremely slow in some cases, and
made other performance improving changes. This improves the performance
of last(1) by as much as 32 times in some cases, and in more typical cases
is about twice as fast.
Added a BUGS section to the manual page to describe the behavior of last(1)
when a login shell terminates abnormally (and thus doesn't write a logout
record to the wtmp file).
