[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...

[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...

[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.
