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)

QUADT long long long
STRTOL(x,y,z) strtol(x,y,z) strtoll(x,y,z)
(from RFC 2389).
add support for MLST & MLSD (machine parseble listings) with 'mlst', 'mlsd'
and 'pmlsd' (mlsd |$PAGER) commands. (from draft-ietf-ftpext-mlst-11)
rename remotesyst() to getremoteinfo(), and modify to parse the result from
FEAT (if supported), and take into account the support for the various
extensions such as MDTM, SIZE, REST (STREAM), MLSD, and FEAT/OPTS.
put each feature into one of the following categories:
- known to work (explicit FEAT)
- unknown but assume works until explicit failure, when it's
then tagged as `known not to work'.
- known not to work (FEAT succeeded but didn't return anything,
or was unknown and then explicit failure)
assign results into features[] matrix.
add support to getreply() so that an optional callback will be called
for each line received from the server except for the first and last.
this is used in FEAT (and MLST) parsing.
modify various commands to check if REST (STREAM), MDTM and SIZE are
explicitly or implicitly supported before using.
fix `syst' when verbose is off.
minor knf (indent goto labels by one space, etc).
simply various command usage handlers by assuming that argv != NULL except
for quit() and disconnect().
* initconn(): use in_addr_t instead of u_int32_t when manipulating IPv6
addresses (and assume anything with ipv6 has in_addr_t; if not, i'll
add an autoconf test for it)
* ai_unmapped(): not all systems have sin_len; so only set #ifdef BSD4_4
* fix some lint
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...
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...

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>
- 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).
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()
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)
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
* abort_remote(): replace borken MIN(4,BUFSIZ) with just BUFSIZ; it
should have been MAX(4,BUFSIZ), but it's probably safe to assume that
BUFSIZ is at least 3... (fix from simonb)
* auth_url(): use the correct variable when calculating a buffer size.
