This restores old behavior where we slept for 1/2 of lease, then tried renewing, thel slept for 1/4 and tried again, etc. But now we will NOT be listening to all packets for 1/2 of lease time, processing (rejecting) everyone else's DHCP traffic.

2021-06-02vi: remove autoindent from otherwise empty linesRon Yorston
Lines that have no content apart from automatic indentation should be treated as empty when the user hits return or ESC. The implementation uses the global variable 'indentcol'. Usually this is zero. It can also be -1 to indicate an 'O' (open above) command, replacing the overloading of the tabstop option bit. A value greater than zero indicates that the current line has been autoindented to the given column (or that the autoindent has been adjusted with ctrl-D). Any other change to the line resets 'indentcol' to zero. Replace strspn() with ident_len(). The latter handles the unlikely case that it's called on the last line of a file which doesn't have a terminating newline. function old new delta char_insert 741 912 +171 indent_len - 42 +42 do_cmd 4781 4785 +4 ------------------------------------------------------------------------------ (add/remove: 1/0 grow/shrink: 2/0 up/down: 217/0) Total: 217 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2021-05-04vi: cursor positioning after whole-line 'y'Ron Yorston
The 'y' command to yank text should leave the cursor at the start of the range. This mostly works correctly in BusyBox vi but not for whole-line yanks with backward motion, e.g. '2yk' to yank two lines backwards. In this case the cursor is left at the end of the range. Fix this by returning the actual range from find_range(). Cursor positioning following whole-line deletion is inconsistent between vim and traditional vi. For BusyBox vi chose the option that uses least code without being exactly compatible with either. Also, find_range() preserved the value of 'dot', the current cursor position. Since this isn't used by either caller of find_range() we can save a few bytes by not bothering. function old new delta do_cmd 4730 4759 +29 find_range 749 686 -63 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/1 up/down: 29/-63) Total: -34 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

seconds This allows to fix a problem that we wait for renew replies for up to half the lease (!!!) if they never come. Make it so that lease of 60 seconds is not "rounded up" to 120 seconds - set lower "sanity limit" to 30 seconds. After 3 failed renew attempts, switch to rebind. After this change, we can have more flexible choice of when to do the first renew - does not need to be equal to lease / 2. function old new delta udhcpc6_main 2568 2576 +8 .rodata 103339 103294 -45 udhcpc_main 2609 2550 -59 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/2 up/down: 8/-104) Total: -96 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

Commit 7a8ceb4eb (vi: changes to line addresses for colon commands) was supposed to address the issue: When the last address is empty it should refer to the current line. This was intended to allow ranges of the form '1,' with an empty last address. It should have been expressed as: When the last address is empty *and the second last isn't* it should refer to the current line. Otherwise a command like ':w' only writes the current line resulting in serious loss of data. function old new delta colon 3906 3911 +5 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/0 up/down: 5/0) Total: 5 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

This is similar to how ':edit' works. - The code for ':edit' included an explicit check that the current filename was non-empty. Both vim and traditional vi accept non-empty filenames, only issuing an error message when an attempt to use such a name fails. - Allow undo of a file read. function old new delta file_insert 367 382 +15 colon 3841 3848 +7 .rodata 105236 105218 -18 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 2/1 up/down: 22/-18) Total: 4 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
