cgd a8ec668ddf convert to use getprogname() 2001-02-19 23:03:42 +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.

lukem 29d497f491 - rename NO_QUAD to NO_LONG_LONG, QUAD* -> LL* and add ULL* (unsigned)
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
2000-08-01 22:47:25 +00:00
lukem 241987dc61 clean up NO_QUAD support: create helper #defines and use as appropriate:
#define		NOQUAD		! NOQUAD
	-------		------		- ------
	QUADF		"%ld"		"%lld"
	QUADFP(x)	"%" x "ld"	"%" x "lld"
	QUADT		long		long long
	STRTOL(x,y,z)	strtol(x,y,z)	strtoll(x,y,z)

lukem d49ddf30cd no trailing , on last item in enum 2000-07-28 11:03:13 +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 2c9a4cf5d0 convert to ANSI KNF 2000-05-01 10:35:16 +00:00
lukem d16e624b57 * Add support for `fget localfile', which reads a list of filenames to
retrieve from localfile.  Based on work by Darren Reed.
* Crank version.
* Update copyright dates.
2000-05-01 09:44:53 +00:00
lukem 7044ee274b define private type `sigfunc' as
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...

lukem ef03015b86 move version into separate file to reduce recompilation after version crank. 1999-12-05 22:54:35 +00:00
lukem bcd625e612 crank version 1999-12-05 22:50:06 +00:00
lukem 7047fe4a36 bump version 1999-11-26 23:26:05 +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 f8a1dcf0d2 - split the version string into product and version
- be consistent about reporting the version between:
	+ status command
	+ about:version URL fetch
	+ User-agent sent in http requests
1999-11-09 22:03:49 +00:00
lukem ed43430a7c support `about:version'. also display the version in the output of `status'. 1999-11-03 07:42:01 +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 08ebd97c48 use sigjmp_buf for sigsetjmp(), instead of jmp_buf.

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 4309cfaab3 enhancments from Marc Horowitz <marc@mit.edu> to improve connection timeouts:
* 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

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 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
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.
1999-07-11 20:37:39 +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 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.

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)

thorpej 7a12770f94 Add "sndbuf" and "rcvbuf" commands for setting the socket buffer sizes,
which in turn can allow the use of larger TCP windows.  This is a work in
progress; there is not yet support for specifying global defaults or
user prefrences on a host/network basis.
1998-07-10 04:39:03 +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 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.
1998-01-18 14:23:33 +00:00
lukem d067f3bbd2 * in recvrequest(), ignore restart_point unless "RETR"ieving. fixes problems
where a remote completion or `mget' would confuse the client a `restart'
  had been issued beforehand. now, `restart' is remembered until an operation
  that can actually use it is invoked.
* in sendrequest(), don't reset restart_point upon entry. fixes `restart'
  for `put' operations.
* if `restart' is invoked with no arguments, print current setting instead
  of displaying a usage
* consistently use printf("%qd", (long long)restart_point) when displaying
  restart_point
* use strto[lq]() instead of atol() when parsing `mark' and `restart' values
* remove unnecessary strlen()s when result of previous snprintf() will do
* replace a few malloc()/strcpy()s with strdup()s
* use SECSPERHOUR instead of '3600'
1997-11-01 14:36:49 +00:00
lukem 87453d32bd Fixes from Todd Miller <Todd.Miller@courtesan.com>:
* use size_t instead of int in places
* use symbolic constants when using access()
1997-09-13 09:05:52 +00:00
lukem 64c651fb96 support $TMPDIR 1997-08-23 07:32:50 +00:00
lukem 2fec2a28f5 bugs fixed:
* don't interpret '-' or '|' when a local filename is determined from
  the remote name (i.e, in mget, and in get with only one argument).
  This is implemented using an extra argument to recvrequest().
  Fixes a major security hole.
* clean up memory leak when using globulize()
* clean up a couple of comments
* fix wording in TNF copyright

features added:
* support for TIS fwtk gate-ftp servers:
	* read defaults from $FTPSERVER && $FTPSERVERPORT
	* start in gate-ftp mode if invoked as 'gate-ftp'
	* toggle or set with 'gate [host [port]]'
1997-08-18 10:20:13 +00:00
lukem b9d5554d5d * use RCSID() && COPYRIGHT() macros
* cleanup for WARNS=1 (including some ugly '(void)&var' bits wrapped in
  #ifdef __GNUC__ to shut up gcc warnings WRT setjmp/longjmp)
* use strtol() instead of atoi(), and more extensively check result of
  conversion
* use u_int16_t instead of short or int for TCP port addresses
1997-07-20 09:45:35 +00:00
lukem a9a78ba448 More enhancements/bugfixes (when will it end?)
* differentiate between being connected, and being logged in
* cleanup some text messages
* support username & password ftp URLs (ftp://user:pass@host/) in non-proxy
  situations; assume proxy supports it for proxy situations.
* cd to / before performing any autofetch transfers
* use strncasecmp in URL parsing. fix from <Todd.Miller@courtesan.com>

christos 067f3f2db4 SMALLFTP->SMALL; remove SMALL from Makefile 1997-03-14 01:39:31 +00:00
lukem 3b5054739d Features:
* support remglobbing of auto_fetch arguments
* new flag - '-e'; disable editing
* "page file" == "get file |${PAGER-less}"

Bugfixes/cleanup:
* consistently use a trailing '.' on messages
* code cleanup, including buffer overrun fixes, use puts
  and putchar in places, etc (inspired by OpenBSD mods)
* disable progress bar when local-file is a pipe or '-'
* skip \r in http headers
* fix remote ftpd slash bug more elegantly (so it works with ////)
* abort_remote(): check if cout==NULL before using it. should fix [bin/3273]
* fixed up cosmetic problems when complete_remote() generated errors from the
  remote server (such as "no files found", "login with user and pass", ...)
  done by adding extra argument to remglob(), which is a pointer to an error
  buffer to put messages in rather than printing to stdout.
1997-03-13 06:23:11 +00:00
lukem 3a50014d60 [Yet Another Huge Ftp Commit - hopefully the last for a while,
barring any more little things people want added ...]

New features:
* progressmeter is now asynchronous, so "stalled" transfers can be
  detected. "- stalled -" is displayed instead of the ETA in this case.
  When the xfer resumes, the time that the xfer was stalled for is
  factored out of the ETA. It is debatable whether this is better than
  not factoring it out, but I like it this way (I.e, if it stalls for 8
  seconds and the ETA was 30 seconds, when it resumes the ETA will still
  be 30 seconds).
* verbosity can be disabled on the command line (-V), so that in auto-fetch
  mode the only lines displayed will be a description of the file, and
  the progress bar (if possible)
* if the screen is resized (and detected via the SIGWINCH signal), the
  progress bar will rescale automatically.

Bugs fixed:
* progress bar will not use the last character on the line, as this can
  cause problems on some terminals
* screen dimensions (via ioctl(TIOCWINSZ)) should use stdout not stdin
* progressmeter() used some vars before initialising them
* ^D will quit now. [fixes bin/3162]
* use hstrerror() to generate error message for host name lookup failure.
* use getcwd instead of getwd (it should have been OK, but why tempt fate?)
* auto-fetch transfers will always return a positive exit value upon failure
  or interruption, relative to the file's position in argv[].
* remote completion of / will work, without putting a leading "///".
  This is actually a bug in ftpd(1), where "NLST /" prefixes all names
  with "//", but fixing every ftpd(1) is not an option...
1997-02-01 10:44:54 +00:00
lukem 7a7fa80740 New features:
* Command line editing via editline(3) library.
* Context sensitive command and file completion, including remote files.

Enhancements to auto-fetch feature:
* Support for http:// URLs using the http protocol, including proxy HTTP
  support via $htty_proxy if it's defined.
* The connection is kept open between successive files on the same host.
  (obviously, this does not count for http requests.)
* Return value of ftp is 0 on no error, or the offset in argv[] of the file
  which failed (i.e., argv[x] failed, ftp returns x).
* If the path in an ftp URL or classic format line has a trailing '/',
  cd to the path and enter interactive mode. Fixes [bin/3011], albiet
  requiring the user to help ftp in determining the operation.

Other changes:
* '-P port' works for normal ftp, and is the default for all classic style
  auto-fetch transfers and for ftp URLs that don't specify the port.
  (previously it would just work for the first xfer.)
* Some code moved into separated files along logical divisions.
* Editing and completion can be compiled out with -DSMALLFTP.
