that `systat doesn't handle errors'. Second off, errx should not be used directly, since
the terminal should be cleaned up before bailing. Third off, whatever we do we need
to be consistent.
There, I feel better now.
1.) fix a bug which caused coredumps when starting with no mode arguments
2.) move to table-lookup for mode-specific command parsing as well.
all command matching is now table-driven.
int overflow. It's now possible to add/display quotas of more than
4G.
XXX I'm sure there is a PR open on this but I couln't find it with the
usual search engines. If someone knows it's number ...
Vastly simplify handling of mode switches, and short-syntax interval
changes. Substring matching of mode names and commands will come
shortly, however the previous method of substring matching modes (it was
not available for commands) is currently not working.
TODO: implement table lookups for mode-specific commands.
table lookup. This will make prefix matching and so on easier.
Expect a similar change for mode-specific commands before too long.
While there, rename some structures with misleading names.
Watch this space for more changes soon.

XXX There are a lot of static arrays in there, bounds should be checked

setuid telnet(1).
i'm not sure why it is here (maybe someone reused this code from
other setuid'ed program, or someone cut-and-pasted the code from
somewhere else?), it was from revision 1.1 (= 4.4BSD).
briefly discussed in: tech-net?
Problem noticed/debugging assisted by giles lean <giles@nemeton.com.au>.
XXX: rate limiting with chunked xfers might not limit correctly (i.e,
the limit may be too high or too low); fixing this is non trivial,
and will probably occur if i ever rototill fetch_url()
the WHOIS service, again. New target: whois.networksolutions.com
This program should be replaced with one that does WHOIS++ so that it
can hit all the registries for data.
* fix bug where the second press of <TAB> on an empty word (i.e, list
all options) may have resulted in an strncmp() against NULL. (detected
by _DIAGASSERT())
for listings of the current working directory; some ftp servers don't
like `NLST .'.

* recvrequest(): treat remote=="" as remote==NULL when calling command().
(to support the above change)
* support `[user@]' in `[user@]host' and `[user@]host[:][path]'.

once per systat invocation, not each time we switch to the bufcache
display.
Fixes core dump noted by Andy Doran when switching back and forth to
bufcache display.
EL_RPROMPT support i added to editline(3).
- allow $FTPPROMPT and $FTPRPROMPT to override defaults for the relevant
prompts
- move `%' formatting code from prompt() to expandbuf().
- implement `%.' and `%c', similar to the same % codes in tcsh(1)
(functionality I added to tcsh nearly 6 years ago), except that `%.'
always does `...trailing' and `%c' always does `/<x>trailing'.
- unknown `%foo' codes get printed as `%foo'
to contain the remote working directory.
- add `set prompt', a user configurable prompt. (defaults to `ftp> ').
the following escape characters a la tcsh(1) are supported: %/, %m,
%M, and %n.
- add global var `username'; used by prompt code
- fix a couple of minor memory leaks
- bump version
standard error, arrange for a non-zero exit status and continue with the
next file. Addresses PR bin/8748.

Problem mentionned in PR 5215 by John Franklin (franklin@bev.net).
Thanks to Perry Metzger for his comments and for reviewing this man page.
the provided port is a valid number use that rather than trying to do
getservbyname() against it.
fixes a problem on foreign systems noted by Chuck Silvers <chuq@chuq.com>
for a while, but showed up due to recent static poisoning.) Note that although
fmt.c builds against ../mail/head.c, this function never actually gets used.
Following examples show the cases.
% ktrace -f - false >/dev/null && echo wrong
wrong
% ktrace -f - -i /usr/sbin/update >/dev/null
(does not return to command line)
That is, back out last change and restore the roles of parent/child for
ktrace(1). The ktruss(1) stuff still remains.
Yes, ktruss(1) has the problems. Better implementation is expected.
- add `usage'; displays the usage of a command.
implemented by calling the c_handler() with argc = 0, argv = "funcname".
- add `passive auto'; does the same as $FTPMODE=auto.
- add `set [option value]'; display all options, or set an option to a value.
- add `unset option'; unset an option.
- add getoptionvalue() to retrieve an option's value, and replace a few
global variables with calls to this.
- implement cleanuppeer(), which resets various bits of state back to
`disconnected'. call in disconnect() and lostpeer().
- support completing on `options'.
- improve recovery after a SIGINT may have closed the connection.
XXX: there's still a couple to fix
other stuff:
- various consistency fixes in the man page.
- ensure that the command usage strings in the code and man page match reality.
- mput/mget: check that the connection still exists before each xfer.
- minor cosmetic changes in confirm().
- set code correctly in sizecmd() and modtime()
- don't need \n in err() strings.
- change lostpeer to take an argument (rather than casting (sig_t)lostpeer
in signal handlers)
- knf and whitespace police.
only return a header length of 0 if we are using -f (force), not
in the case when we know how long the header is. this stops from
playing the audio header.
* simplify main loop (don't need `top' variable any more)
* use a struct sockaddr_in6.sin6_addr for the result from inet_pton(),
rather than u_char buf[16]
* add a few more comments
* confirm(): move from util.c to cmds.c. display mnemonic string in its prompt.
add support for `q' (terminate current xfer), `?' (show help list)
* in various signal handlers, output a linefeed only if fromatty.
* if fgets(stdin) returned NULL (i.e, EOF), clearerr(stdin) because you don't
want future fgets to fail. this is not done for the fgets() in the main
command loop, since ftp will quit at that point.
* unless ftp is invoked with -a, don't retain the anonftp setting between
hosts (`ftp somehost:' sets anonftp, but you don't want that to `stick'
if you close that connection and open a new one).
stage. if this occurs, just call lostpeer() to close the connection. whilst this
might be considered brutal, it's also extremely handy if you're impatient or there's
lossage at the remote end.
don't save the signal mask on some foreign systems.
* ensure signal handlers don't use stdio and do reset errno if they
don't exit with siglongjmp()
* use a common SIGINT handler for {send,recv}request()
(work around editline's override)
* minor cleanup of signal handler (along the lines of similar work in
recvrequest()). the handlers should now be reset everytime the cleanup
handler was callled.
prints out info if bytes > 0). only set the handler if SIGINFO is defined
* hijack SIGQUIT to be the same as SIGINFO (foreign ports have this, and it's
annoying to have SIGQUIT dump core on netbsd when it prints info on other
systems)
* in {recv,send}request(), factor a lot of duplicated code out into a
`cleanup' section at the end
* rework shell() a bit
* implement xsignal_restart(), which only sets the SA_RESTART flag if
specifically requested
* xsignal() is now a wrapper to xsignal_restart(). INFO, USR1, USR2 and WINCH
are restartable, ALRM, INT, PIPE and QUIT are not.
* improve getreply()'s timeout code to take advantage of the above.
other changes:
* improve wording of how globbing works for `classic' URLs (host:path).
suggested by John Refling <johnr@imageworks.com> in relation to PRs
[bin/8519] and [bin/8520]
* always compile in the `edit' command even if NO_EDITCOMPLETE defined.
it's just a no-op in the latter case, which is more consistent to
the users.
* always compile in about: support (i.e, remove NO_ABOUT).
i'm entitled to some vanity in this program...
* clean up some whitespace
the disabled state can be overridden by toggling epsv4.
(I got sick of the errors about EPSV not being supported on almost
every server I connect to. This way we retain support for epsv4, but
it's not so whiny after the first failure...)
to "extern" if it's not set. define GLOBAL to (empty) in main.c.
this effectively moves all the globals into main.c whilst retaining
namespace access to them in other source files.
(global vars in header files confuse foreign linkers)

* parse_url(): improve checking of portnum, and add an extra argument to pass
back the parsed portnum to the caller (reduces a bit of code duplication)
* Move the KAME/WIDE copyrights after the BSD/TNFi ones. Since there was
significantly less code added under the former, it's only fair on the latter.
