[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...

[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.

[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.
