after the chunksize (before the \r\n), Apache 1.3.11 puts *multiple*
trailing spaces after the chunksize. I 'm fairly certain that this is
contrary to RFC 2068 section 3.6, but whatever...

it to a numeric port number
* use parseport() in parse_url() and hookup()
* don't try and lookup the port number using getaddrinfo(), as it's too hard
to separate a failed host name lookup from a failed service name lookup.
this was causing lossage on systems that don't have `http' in services(5)
(such as solaris), but only crept in when we started using getaddrinfo()
unconditionally.
equivalents. name change suggested by Klaus Klein <kjk@netbsd.org>
- change defined(BSD4_4) || HAVE_SIN_LEN tests into HAVE_SOCKADDR_SA_LEN,
and set the latter if BSD4_4 exists
paths. (lukemftp will provide replacements for these on older systems)
* rename __USE_SELECT to USE_SELECT
* rename BSD4_4 to HAVE_SIN_LEN
* replace union sockunion {} with struct sockinet {}, and modify the code
accordingly. this is possibly more portable, as it doesn't rely upon the
structure alignment within the union for our own stuff.
(XXX: haven't tested the ipv6 stuff)

call remotesyst() only when login has been successful
some servers don't let you run SYST until you've successfully logged in.
* in fetch_ftp(), always call setpeer() with autologin disabled, and use
the following ftp_login() to DTRT.
this prevents ftp from trying to login a second time if the first autologin
fails when connecting to a remote site anonymously using autofetch.
* reset unix_proxy and unix_server in cleanuppeer()
* missed a function conversion in the KNF sweep...
* sanity check a length (otherwise certain bogus responses can crash ftp)
* allow a transfer encoding type of `binary'; certain firewall vendors
return this bogus type...
send Host: directive with RFC2732 bracket notation for IPv6 numeric,
otherwise "host:port" is ambiguous to servers (clarification will be submitted
as update to RFC2732).
typedef void (*sigfunc) __P((int));
and replace use of sig_t and void (*)(int).
certain other OSes define sig_t differently to that (they add extra arguments),
and it causes problems due to function mismatches, etc...
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()
for listings of the current working directory; some ftp servers don't
like `NLST .'.
[noted by Giles Lean <giles@nemeton.com.au>]
* recvrequest(): treat remote=="" as remote==NULL when calling command().
(to support the above change)
* support `[user@]' in `[user@]host' and `[user@]host[:][path]'.
[based on idea (and initial code) from David Maxwell <david@fundy.ca>]
* `idle' may be invoked without any args
* reformat some comments
* reformat usage string in program and man page
* call updateremotepwd() after successful login, not after successful connect
* always call setsockopt(, IPPROTO_IP, IP_TOS, ) (et al); using #if
defined(IPPROTO_IP) doesn't work on certain foreign systems where
enums instead of #defines are used...
[noted by Matthias Pfaller <leo@dachau.marco.de>]
- 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.
* 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).
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
should be in host order. found/fixed by Matthias Pfaller <leo@dachau.marco.de>
* 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.
lpage page local files
pdir as dir, but through your $PAGER
pls as ls, but through your $PAGER
* implement docase() (a la dotrans() et al) and use appropriately, rototilling
some duplicated code
* globulize(): modify to return a pointer to the strdup()ed result in all cases,
and hack the code that calls it to take this into account
* replace strcpy() and strncpy() with strlcpy()
* put(), getit(): use some aptly named local vars instead of argv[...]
* delint
prototype for idle() in <unistd.h> (which i thought was against namespace
and sensibility guidelines, but...)
* consistently use xsignal() instead of signal(). we get known behaviour
in all cases (SA_RESTART), which is good for some borken foreign systems.
* remove signal.h from most files; it's unnecessary now
* fetch_url(): use `long chunksize' instead of ssize_t; it's more portable, and
we're setting chunksize with strtol() anyway
* xsignal(): only use SA_RESTART if it exists. SunOS 4.x doesn't have it
but has the inverse (SA_INTERRUPT). the original function i was inspired
from had this support (lib/signal.c, W. Richard Stevens' `UNP 2nd ed Vol 1').
* remove <termios.h> from util.c; it should be unnecessary now
