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.
remove server from using a persistent connection, which speeds
up such requests.
* support http 301 and 302 redirects
* rewrite guts of url_get() to use fparseln() et al instead of
read(s,&p,1)... enables each in the header to be parsed
as necessary
* rename login to ftp_login, to remove conflict with util.h::login
* cleanup verbose messages during http proxy requests
* 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]]'
* 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
* 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.
