cgd a8ec668ddf convert to use getprogname() 2001-02-19 23:03:42 +00:00
jdolecek 8e4be8f5bb call setlocale() on startup 2001-01-09 22:25:55 +00:00
lukem 8ec0002acd invoke cmdtab.c_handler()s with argv[0] == c_name instead of the
supplied name. that way the full (unambiguous) name is displayed in
error messages and usage strings.
2000-12-15 02:22:50 +00:00
lukem ecd3d78091 - implement "mreget"; as per "mget" but uses "reget" instead of "get"
- add -N netrc and $NETRC, as methods to select an alternative .netrc file
- cache local user name and home directory for further use
- in mget(), use docase() instead of a local version to do the case
  conversion.
2000-11-15 00:10:59 +00:00
lukem 7816d2586e add support for FEAT and OPTS commands with `features' and `opts'.
(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().

lukem f48d57e2d2 portability fixes for lukemftp:
* 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
2000-06-11 02:12:05 +00:00
lukem 413a4004df Add support for 'ftp -u url file ...', to upload a list of files to given url.
Mostly based on [bin/10019] by Scott Aaron Bamford <sab@ansic.net>
2000-05-31 14:23:57 +00:00
lukem 2c9a4cf5d0 convert to ANSI KNF 2000-05-01 10:35:16 +00:00
lukem d0090fb777 * implement xsl_init() and xsl_add(); error checking forms of sl_{init,add}()
* 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())
1999-11-28 06:32:04 +00:00
lukem f25449279d * complete_remote(): use remglob("", ...) instead of remglob(".", ...),
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>]
1999-11-26 21:41:55 +00:00
lukem ecb8a0755a - implement `set rprompt'; right side version of `set prompt'. depends on
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'
1999-11-12 02:50:38 +00:00
lukem 14fbd5079e - implement updateremotepwd(); update the global variable `remotepwd'
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
1999-11-11 02:53:02 +00:00
lukem 4f2d3550d0 new features:
- 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.

lukem f74df4b2ea * fix up confirm() (broke `a' and `p' in last commit)
* 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
1999-10-13 02:47:54 +00:00
lukem da626f2307 a few user interface and cosmetic tweaks:
* 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).

lukem bd5207d5ac if editing is enabled when intr() is called, print a newline. (cosmetic fix) 1999-10-11 12:34:17 +00:00
lukem a53d7d57a9 * use sigsetjmp()/siglongjump() instead of setjmp()/longjmp(); the latter
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()
1999-10-09 03:00:55 +00:00
lukem 3f8b92b0b3 * factor out SIGINFO setting into a handler that is always active (but only
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
1999-10-05 13:05:39 +00:00
lukem f45505380a add TNFi copyright to all files i've done more than a minor amount of work to... 1999-10-05 01:16:11 +00:00
lukem fcb1a22a1c If EPSV or EPRT fails, disable epsv4 for the rest of the current connection.
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...)
1999-10-01 08:01:12 +00:00
lukem ad70c1982e prefix the global variables in ftp_var.h with GLOBAL, which defaults
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)
1999-10-01 06:55:44 +00:00
lukem 46111773d1 * don't bother with "pathnames.h"; it contained just a single #define.
instead, include <paths.h> in the files that need it
* slightly reorg ftp_var.h
1999-10-01 06:18:32 +00:00
lukem 25790d921d * In the !NI_NUMERICHOST case (i.e, getaddrinfo() challenged systems), portnum
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.
1999-09-30 23:51:26 +00:00
lukem 1b3e840242 * fix initialisation of home[]
* fetch_url(): if path would be NULL, return strdup("")
1999-09-30 12:18:03 +00:00
lukem 256fc138f1 * add new commands:
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
1999-09-28 06:47:38 +00:00
lukem 70c01ac44a * idle(): rename to idlecmd(). certain linux distributions have an incompatible
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
1999-09-27 23:09:42 +00:00
lukem cb8c56db8a if getsockopt() returns a buffer size of <= 0, set them to 8192.
this works around a problem in certain OS from Sun with a version < 5.6...
1999-09-24 06:14:40 +00:00
lukem 700e3c1ec7 * add support for `xferbuf', which sets both `sndbuf' and `rcvbuf'
* document the above three commands
* rototill the way the sndbuf and rcvbuf work. remove resetsockbufsize()
* use the appropriate socket buffer size as the size of the buffer that
  the read()/write() loops use. speeds up things in some cases.
1999-09-22 07:18:31 +00:00
lukem 26738e38b8 only default to epsv4 if INET6 is defined 1999-09-21 10:11:56 +00:00
lukem 375a0efb60 * change fetch_ftp() to be fully rfc 1738 compliant; if the URL contains
the an empty directory (e.g, between `some' and `path' in
  `ftp://host/some//path'), then execute `CWD ' (without a path).
  This command will probably fail on rfc 959 compliant servers, so
  issue a warning in this case and bail. [noted by cgd].
  (i wonder if the people who wrote rfc 1738 actually realised that this
  requirement appears to contravene the spec for `cwd' in rfc 959 ?)
* replace isurl() with isipv6addr(), and use appropriately. fixes
  auto-login with `classic ftp URLs' (e.g, `ftp somehost:')
* cleanup and rework some of the ipv6 stuff in parse_url()
* prevent potential coredump in fetch_ftp() when parsing `;type=X'
* KNF a few lines
* fix a couple of comments
* cleanup the man page a bit
1999-07-12 13:20:34 +00:00
itojun 940276557f add epsv4 command, which enable/disable the use of EPSV/EPRT.
this is mainly for (hypothetical) ftp server which disconnect clients
that use EPSV/EPRT.  I've never seen any ftp server like this, but
epsv4 command may be of use when such an ftp server is found.

christos 7e3d65379b isurl does not return a pointer! 1999-07-10 19:41:15 +00:00
itojun d1a8e792f7 add dual-stack (IPv4/v6) support. hope I broke no other part... 1999-07-02 08:07:40 +00:00
lukem e25749a582 [fear this; more ftp hacking from lukem :-]
features:
---------
* transfer rate throttling with the new `rate' command. syntax:
	rate direction [max [incr]]
  where direction is `all', `get' or `put'.
  if max is not supplied, the current settings are displayed.
  if max is supplied, then transfers in the given direction will
  be throttled to this value.
  if incr is supplied, the increment for the `on-the-fly' scaling
  will be set to that, otherwise `1024' is used.
  currently implemented for binary get, binary put, and url fetches.
  not yet supported for ascii get or put, or local file copies.
* on-the-fly scaling of the throttle based on signals:
    - SIGUSR1 raises the throttle rate by the increment for that direction
    - SIGUSR2 lowers the throttle rate by the increment for that direction
* -T dir,max[,incr] option to set rate from the command line
* `k', `m', `g' suffix support for bytecounts in the `hash', `rate',
  `rcvbuf' and `sndbuf' commands)

bug fixes and code mods:
------------------------
* fix up ftp_login() so that ruserpass() is always called, even for
  command-line url fetches.
* implement strsuftoi(), which parses a given number into a int with
  suffix support. replaces getsockbufsize()
* implement parserate(), which does the argv parsing for -T and rate
* save and restore errno in signal handlers (may not be necessary, but
  it doesn't hurt)

notes:
------
the rate command has had reasonable testing, but I'd like feedback
if it doesn't do the right thing, especially from people on slower
(i.e, modem) links.
I haven't tested the rate throttle against a http server which does
`transfer-encoding: chunked' because I couldn't find a server to
test against.

cgd d78b6bd31e split the "SMALL" #ifdefs into ones for NO_ABOUT, NO_EDITCOMPLETE, and
NO_PROGRESS.  -DSMALL still implies all of those.  progress meter support
isn't necessary for the smallest possible ftp client, but it adds very
little space and makes users' lives much better.  Therefore, it should
be enabled for installation media if at all possible.
1999-06-20 22:07:28 +00:00
lukem f7540e6f75 * fix gate mode to login as `user@realhost' rather than using PASSERVE;
the latter only seemed to work for TIS Gauntlet and not TIS fwtk.
  thanks to simonb@netbsd.org for testing this. fixes [bin/5556].
* if EOF (e.g, ^D) is entered at a username/password/account prompt which
  happens to use fgets(), exit the login rather than treating EOF as CR.
* don't use the comma operator where separate statements are valid
* always use snprintf to copy stuff into malloced buffers, just in case
  typos creep in and mean that the buffer ends up being overflowed
1999-06-02 02:03:57 +00:00
lukem dedd2f772c only enable editing by default if stdin is a tty.
noticed by Onno van der Linden <onno@simplex.nl>
1999-05-17 04:26:45 +00:00
lukem 82f739bcb0 when using editline, work on the correct buffer. fixes problem where blank
input lines were being added to the history buffer.
1999-03-31 02:00:42 +00:00
lukem bed9aad370 * implement -R; restart non-proxied command-line FTP xfers
* fix fetch_ftp() so that hcode parsing is not done for file:// urls
  (a } in the wrong place, and code at the wrong indent level...)
* change outfile to being a global (so it gets correctly reset)
* change parse_url to not remove leading '/' for non ftp urls.
  whilst this is not totally rfc1738 compliant, other code kinda
  assumes this is the case, and it doesn't hurt
1999-03-22 07:36:40 +00:00
lukem 5a1118c5f9 * add url_decode() - `in-place' decode %xx escapes in a given url component
* parse_url()
-   only look for user[:pass] for an ftp url (per rfc1738)
-   strip leading /'s in an ftp url. (almost per rfc 1738)
* fetch_url()
-   decode a copy of the path and use that to build local filenames
-   send port in http Host: header (suggested by cgd@netbsd.org)
* fetch_ftp()
-   url_decode() the user, pass and path
-   fix splitting of path into dir & file (partially from [bin/7073])
-   don't bother caching the last host; it can cause problems when
    using ftp:// transfers, or when the user changes between xfers
* improve documentation of auto-fetched url arguments (especially regarding
  escape sequences in ftp:// urls)
* some whitespace & copyright updates

this should fix [bin/7073] William O Ferry <woferry@warp.wofme.com>,
as well as the metaissues raised in that PR.
1999-03-08 04:36:12 +00:00
lukem 0bd80459cb * -v enables verbose & progress, -V disables both
* set setvbuf(ttyout, NULL, _IOLBF, 0) and remove a bunch of fflush(ttyout).
* use fwrite() instead of write() for progressmeter (don't intermix stdio
  with non stdio ops)
1999-01-24 02:39:29 +00:00
lukem 0e87f1b53d support -f, which forces a cache flush for http xfers using either
`Pragma: no-cache' (http/1.0) or `Cache-Control: no-cache' (http/1.1)
1999-01-23 15:46:24 +00:00

lukem 887627831e * add transfer rate to progress meter. (suggested by hubert feyrer)
* fix up progress meter display for files once > ~20.47MB has been
  transferred.  (noted by darren reed)
* use xsignal() for SIGWINCH, so window resizes don't abort xfers on
  drainbamaged systems.
* don't assume that TIOCGWINSZ returns a non zero width.
1998-09-28 09:03:22 +00:00
lukem 4c105ef56e need <signal.h> for signal.... 1998-08-08 03:15:44 +00:00
lukem 4a8ec5494d features:
* support $no_proxy, which is a comma or space separated list of
  host[:port] elements for which proxying is to be disabled.
  (asked for by cgd in [bin/5027])
* if $FTPANONPASS is defined, use that as the anon ftp password
  (instead of "`whoami`@")
* allow http URL's without a filename as long as an output file
  is specified.

other stuff:
* implement parse_url(), which breaks up a URL into its bits, and use.
* simplify url_get() and auto_fetch() to use parse_url() and to not
  modify the supplied URL or a copy of it.
* implement xmalloc() and xstrdup(); error-checked malloc()/strdup()
* add more consistency to messages, quoting strings in output as `%s'
1998-08-03 01:49:25 +00:00
lukem 9a6e9b2ce7 some fixes & enhancements from openbsd's ftp, with extra fixes by me:
* default to passive with active fallback. $FTPMODE modifies this behaviour.
  -A forces active connection.
* support '-o outfile' for auto-fetched files. outfile can be a file,
  `-' (for stdout), or '|command' (to output each file through command).
* support '-r waittime', which retries the connection after waittime seconds
  if it fails.
* fix 'page file' when restart is non-zero.
* try all ip-addresses of a host in a http fetch (as the normal ftp fetch
  does).

XXX: a ``broken pipe'' error sometimes occurs with -o '|command';
i haven't tracked this down yet.

lukem 6ab4bdf006 define MAX_IN_PORT_T and use instead of USHRT_MAX. suggested by cgd@netbsd.org 1998-01-18 22:09:39 +00:00
lukem 7ee412ebee * ensure buffer for username is initialised, so ^D on username prompt
doesn't use garbage for the username.  from "Soren S. Jorvang" <soren@t.dk>
  in [bin/4559]
* use in_port_t for ports, and USHRT_MAX instead of 0xffff
  (from millert@openbsd.org)
* use `NULL' instead of `(.... *)0' where appropriate.
