* 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)
* in autofetch mode, don't attempt to 'cd /' on first xfer (only on
subsequent xfers), as some ftp daemons don't permit that.
[noted by dbj@netbsd.org].
XXX: code could be smarter (but a lot more complicated to boot); this
works for now.
* 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'
* parse Last-Modified: HTTP headers for date, and change time of
retrieved file if parsing succeeded
* support file:/// and file://localhost/ URLs
* in url_get(), re-write byte moving code to consistently use fread()
and fwrite(), and check errors at end with ferror()
* add about:* easter-egg (#ifndef SMALL :-)
* 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.
* 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 && $FTPSERVERPORT
* start in gate-ftp mode if invoked as 'gate-ftp'
* toggle or set with 'gate [host [port]]'
* differentiate between being connected, and being logged in
* cleanup some text messages
* support username & password ftp URLs (ftp://user:pass@host/) in non-proxy
situations; assume proxy supports it for proxy situations.
* cd to / before performing any autofetch transfers
* use strncasecmp in URL parsing. fix from <Todd.Miller@courtesan.com>
* add "more" & "less" as synonyms for "page"
* move editline setup code into controlediting(), and call appropriately.
only setup setup terminal if going into interactive mode. inspired
by Todd Miller <todd.miller@courtesan.com>
* support remglobbing of auto_fetch arguments
* new flag - '-e'; disable editing
* "page file" == "get file |${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.
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...
* 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.
* implement 'progress bar/meter' (inspired by ncftp). use 'progress' to
toggle on. it will display current file size to 5 digits, automatically
determining suffix (up to 16384 P (petabytes) == 2^64).
* 'ls' now uses NLST (unadorned listing), a la older ftp clients. 'dir'
still does LIST (long listing). idea from John Nemeth <jnemeth@cue.bc.ca>
bug fixes:
* return first line of reply in reply_string[] from getreply(), instead
of last line. This fixes [bin/741] (parsing of SYST), and also means
that SIZE and MDTM messages will be parsed correctly if they're longer
than 1 line.
* parse URL-style auto-ftps that have no filename correctly
(e.g, ftp://host, ftp://host/, ftp://host/dir/). pointed out by
Jaromir Dolecek <dolecek@saruman.ics.muni.cz>
* pass the correct size array in 2nd arg of utimes() when setting the
modification time
friedman@gnu.ai.mit.edu (Noah Friedman) made to his modified ftp:
- implement "lpwd" - local pwd
- implement "preserve" - toggle preserving of file modification
times on retrieved files
- allow for explicit "on" or "off" arg to toggle commands
- "exit" synonym for "quit", "msend" synonym for "mput"
- in confirmation mode, allow 'a' (yes to rest of current command),
and 'p' (turn off prompt mode, as if 'prompt off' was done,
effective immediately)
- "modtime" returns time formatted as localtime, not GMT
Bug fixes:
- check for extraneous args on commands
- cleanup const usage, line formatting
- create 0 length temporary file in remglob() to prevent symlink games
(from OpenBSD)
- check length of filename of ~/.netrc (from OpenBSD)
- don't echo 'ACCT' parameter when debugging (a la 'PASS')
- Fix checking of directory access for "/foo", the parent
directory is "/", not "" (from FreeBSD)
- remove trailing whitespace on lines
- add any missing NetBSD tags
- cleanups to man page, includinging sorting options description
feature additions:
- variable sized hash marks (from [bin/683], but done in the hash command
as an optional arg)
- more user-friendly transfer time printing (from FreeBSD, with mods)
- '-p' command line option to jump into PASV mode (closes [bin/2857],
but with an option rather than checking argv[0])
- SIGINFO support for printing xfer stats when sending/receiving requests
- '-P port' for changing the port to connect to (from thorpej@netbsd.org)
- '-a': bypass normal login, and try anonymous login (from OpenBSD
via thorpej)
- autofetch files via url (ftp://...) or "classic" (host:/file)
(from OpenBSD via thorpej)
- 'ftp' synonymous with 'open' (from FreeBSD)
Alphabetize description of command line flags.
Packet tracing is an unimplemented feature, I've decided to keep it's
documentation since ever other UN*X vendor I checked still does. Not
a particularly useful reason.
