* implement ftpvis(), which \ quotes the following in the given string:
SP, TAB, \, CR, "
* use ftpvis() in complete_ambiguous(), to escape characters in a word
which would confuse makeargv()/slurpstring().
* 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)
a response, and return the base64 encoded response. only the `Basic'
scheme is supported.
* implement base64_enc(), which base64 encodes the given buffer
* add support for http response codes 401 "authorization required" and 407
"proxy authorization required", using auth_url(). [requested by veego@]
do_fetch() - which retrieves one file calling fetch_url() or fetch_ftp()
as necessary.
* don't http redirect more than 5 times for a given url
* send `User-Agent: NetBSD-ftp/1.4' header in http requests. (suggested
by Christoph Badura <bad@ora.de>)
* cleanup http return code parser, and add support for:
- 300 `Multiple Choices' - but only if the server returns a
preferred url in a Location: header because i'm *not* adding
a html parser to provide the user with options.
- 305 `Use Proxy [given in Location: header]'. (XXX: not tested)
* support http redirects to non-proxied ftp://urls. (bug discovered by
Chris Demetriou <cgd@netbsd.org>)
* auto-login to an ftp site (using the FTP protocol) if an ftp://host/dir/
style url is given and ftp_proxy is set. whilst this is less orthoganol
with other ftp://host/file urls it's *much* more convenient.
1. changed to use timegm(3) on NetBSD and
2. supply alternative code for other Unix-like OSs
(NetBSD ftp shall be portable for some reasons :-).
This fix closes PR #6448.
NOTE: This should be fixed again if a portable UTC to time_t
conversion method is specified in some standards.
* 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.
* 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.
* 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 :-)
