2021-03-29vi: allow repetition count for paragraph motionRon Yorston
The paragraph motion commands '{' and '}' should accept a count. function old new delta do_cmd 5054 5071 +17 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/0 up/down: 17/0) Total: 17 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2021-03-29vi: allow motion count for change/delete/yank/shiftRon Yorston
The motion that determines the range of a change, delete, yank or shift operation can have its own count. Thus the commands '5dd' and 'd5d' are equivalent: both delete 5 lines. When the command itself also has a count the two values are multiplied. Thus the command '2d3w' deletes 6 words and '2D3G' deletes from the current line to line 6. (When dealing with structured data it might make sense to think in units of 3 words so '2d3w' is deleting 2 such units. It doesn't seem quite as sensible to express 'delete from current line to line 6' as '2D3G' but vi permits it.) function old new delta get_motion_char - 68 +68 ------------------------------------------------------------------------------ (add/remove: 1/0 grow/shrink: 0/0 up/down: 68/0) Total: 68 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2021-03-29vi: remember cursor column during vertical motionRon Yorston
When the 'j'/'k' commands or up/down arrow keys are used to move the cursor vertically 'vi' remembers the original cursor column and positions the cursor there if possible. Also, if the '$' command has been used to position the cursor at the end of a line vertical movements keep the cursor at the end of the line. Make BusyBox 'vi' do the same. function old new delta refresh 674 694 +20 do_cmd 4853 4861 +8 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 2/0 up/down: 28/0) Total: 28 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2021-03-29vi: 'G'/'M' commands move to first visible characterRon Yorston
The 'G' command with no target (meaning 'go to last line') should position the cursor on the first visible character of the line, as it already does in other cases. The 'M' command should position the cursor on the first visible character (as 'H' and 'L' already do). function old new delta do_cmd 4842 4853 +11 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/0 up/down: 11/0) Total: 11 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2021-03-29vi: don't overwrite existing fileRon Yorston
If the name of the file being written doesn't match the current filename and the output file already exists vi should issue a warning and not overwrite the file. Because the test only compares the file names it's somewhat over- protective. If the current file name is 'my_text' and the user tries to save to './my_text' they'll be prevented from doing so. function old new delta colon 3092 3151 +59 .rodata 105118 105146 +28 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 2/0 up/down: 87/0) Total: 87 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2021-03-29vi: make buffer handling more vi-likeRon Yorston
Vi places text affected by change/delete/yank operations into a buffer. The contents of such buffers can be restored with the put commands, 'p' or 'P'. These behave differently depending on whether the buffer contains whole lines or partial lines. For whole lines the text is copied into the file on the line before (P) or after (p) the current line. For partial lines the text is copied before or after the current cursor position. Whether an operation results in whole or partial lines depends on the command used. BusyBox vi treats any buffer with a newline as though it contained whole lines. This is incorrect. Deleting multiple words across a line boundary results in a buffer with a newline but not having whole lines. Rework how buffers are handled to behave more like vi. function old new delta static.text_yank 79 99 +20 colon 3092 3097 +5 edit_file 885 887 +2 yank_delete 127 112 -15 .rodata 105139 105101 -38 find_range 514 467 -47 do_cmd 5088 4842 -246 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 3/4 up/down: 27/-346) Total: -319 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2021-03-29vi: code shrinkRon Yorston
I was puzzled by code in find_range() which handles forward word movement. It included a test to see if we're at the start of a word. Since these are forward word movements surely we'd expect to be at the start of a word? In fact, the test was intended to fix a problem with changes to the last word in a file, as discussed in the thread starting here: http://lists.busybox.net/pipermail/busybox/2004-January/044552.html The code can be simplified by testing directly for end of file instead of indirectly for not being at the start of a word. Since trailing whitespace is now handled in do_cmd() the code to back up off a newline is no longer required. function old new delta find_range 619 514 -105 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-105) Total: -105 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2021-03-29vi: fix word operations across line boundariesRon Yorston
Commit 4b49422a0 (vi: fix changes to word at end of line. Closes 11796) fixed a problem where an operation on a word at the end of a line followed by a line starting with whitespace incorrectly joined the lines. However it also broke the case where operating on multiple words across a line boundary *should* join the lines. Fix this by detecting when trailing whitepace in a word operation includes a newline. Whitespace beyond the newline is excluded from consideration. function old new delta do_cmd 5083 5088 +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>

2021-03-16udhcpc: ignore zero-length DHCP optionsRussell Senior
Discovered that the DHCP server on a TrendNet router (unknown model) provides a zero-length option 12 (Host Name) in the DHCP ACK message. This has the effect of causing udhcpc to drop the rest of the options, including option 51 (IP Address Lease Time), 3 (Router), and 6 (Domain Name Server), most importantly leaving the OpenWrt device with no default gateway. The TrendNet behavior violates RFC 2132, which in Section 3.14 declares that option 12 has a minimum length of 1 octet. It is perhaps not a cosmic coincidence that I found this behavior on Pi Day. This patch allows zero length options without bailing out, by simply skipping them. function old new delta udhcp_scan_options 183 172 -11 Signed-off-by: Russell Senior <russell@personaltelco.net> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2021-02-18libbb: fix '--help' handling in FEATURE_SH_NOFORK=yDenys Vlasenko
Most BusyBox applets respond to the '--help' option by printing a usage message. This is normally handled by busybox_main() so applet main routines don't have support for '--help'. In standalone shell mode with FEATURE_SH_NOFORK enabled nofork applets are invoked directly, bypassing busybox_main(). This results in inconsistent handling of '--help': - applets which call getopt() report "unrecognized option '--help'" and print help anyway; - realpath says "--help: No such file or directory" and doesn't print help; - usleep says "invalid number '--help'" and doesn't print help. Avoid inconsistency by checking for '--help' in run_nofork_applet().

054493350 ("Do not add -lresolv on non-Linux systems") adds a condition to link with libresolv only on linux systems. The check requires that CONFIG_UNAME_OSNAME equals Linux. This works only if the uname applet is enabled. Otherwise, CONFIG_UNAME_OSNAME is empty, regardless of the platform. By default, CONFIG_UNAME_OSNAME is the output of uname -o. For most linux systems, uname -o returns "GNU/Linux" and the check fails. In this case, linking a static busybox fails because of missing symbols from libresolv. networking/lib.a(nslookup.o): In function `add_query': nslookup.c:789: undefined reference to `__res_mkquery' networking/lib.a(nslookup.o): In function `parse_reply': nslookup.c:355: undefined reference to `ns_initparse' nslookup.c:361: undefined reference to `ns_parserr' nslookup.c:404: undefined reference to `ns_name_uncompress' nslookup.c:418: undefined reference to `ns_get16' nslookup.c:419: undefined reference to `ns_name_uncompress' .. nslookup.c:456: undefined reference to `ns_get16' ... nslookup.c:469: undefined reference to `ns_name_uncompress' ... nslookup.c:489: undefined reference to `ns_get32' ... collect2: error: ld returned 1 exit status This patch uses the output of $CC -dumpmachine to detect the target platform for which we compile.

2021-02-03libbb: code shrink fgets_strRon Yorston
Use a NULL value of maxsz_p to indicate to xmalloc_fgets_internal() that the caller doesn't care about the maximum size of the buffer. This allows the default maximum size to be set once in xmalloc_fgets_internal() instead of separately in each caller. function old new delta xmalloc_fgets_internal 273 287 +14 xmalloc_fgets_str 30 9 -21 xmalloc_fgetline_str 33 12 -21 xmalloc_fgets_str_len 38 10 -28 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/3 up/down: 14/-70) Total: -56 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2021-02-02nl: ensure '-b n' option displays file contentRon Yorston
The command 'nl -b n' should output no line numbers, just some spaces as a placeholder followed by the actual file content. Add tests for line numbering by cat and nl.
