udp_io, traceroute: Standardise IPv6 PKTINFO handling to be portable

2017-10-30T15:06:50+00:00

The current standard (RFC 3542) is for IPV6_RECVPKTINFO to be given to setsockopt, and IPV6_PKTINFO to be used as the packet type. Previously, RFC 2292 required IPV6_PKTINFO to be used for both, but RFC 3542 re-purposed IPV6_PKTINFO when given to setsockopt. The special Linux-specific IPV6_2292PKTINFO has the same semantics as IPV6_PKTINFO in RFC 2292, but was introduced at the same time as IPV6_RECVPKTINFO. Therefore, if we have IPV6_RECVPKTINFO available, we can use the RFC 3542 style, and if not, we assume that only the RFC 2292 API is available, using IPV6_PKTINFO for both.

lineedit: improve multiline PS1 - redraw using last PS1 line. Closes 10381

2017-10-12T16:26:13+00:00

This patch only affects prompts with newlines. We redraw the prompt [+ input] occasionally, e.g. during tab completion, history browsing or search, etc, and we expect it to align with prior redraws, such that the visible effect is that only the input changes. With multi-line PS1, redraw always printed the prompt some lines below the old one, which resulted in terminal scroll during every redraw. Now we only redraw the last PS1 line, so vertical alignment is easier to manage (we already calculated it using only the last line, but re-drew all lines - that was the culprit), which fixes those extra scrolls. Notes: - We now use the full prompt for the initial draw, after clear-screen (^L), and after tab-completion choices are displayed. Everything else now redraws using the last/sole prompt line. - During terminal resize we now only redraw the last[/sole] prompt line, which is arguably better because it's hard to do right (and we never did). - Good side effect for reverse-i-search: its prompt now replaces only the last line of the original prompt - like other shells do. function old new delta put_prompt_custom - 66 +66 draw_custom - 66 +66 parse_and_put_prompt 766 806 +40 read_line_input 3867 3884 +17 input_tab 1069 1076 +7 cmdedit_setwidth 61 63 +2 redraw 59 47 -12 put_prompt 46 - -46 ------------------------------------------------------------------------------ (add/remove: 2/1 grow/shrink: 4/1 up/down: 198/-58) Total: 140 bytes Signed-off-by: Avi Halachmi Signed-off-by: Denys Vlasenko
