| * vi: allow repetition count for paragraph motionRon Yorston2021-03-291-9/+8

| * vi: allow motion count for change/delete/yank/shiftRon Yorston2021-03-291-2/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| * vi: make buffer handling more vi-likeRon Yorston2021-03-291-89/+73

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>
| * vi: code shrinkRon Yorston2021-03-291-9/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
| * vi: fix word operations across line boundariesRon Yorston2021-03-291-7/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 90f35327c (libbb: avoid problems with quoted characters in tab completion) avoided a conflict between the code to quote special characters and that to display case-preserved filenames. Here's another one. I'd installed a third-party binary on Microsoft Windows and wanted to execute it from a busybox-w32 shell which didn't have it in its path. No problem: $ c:/prog<tab> $ c:/Program<tab> Program Files/ ProgramData $ c:/Program\<tab> $ c:/PProgram I was too quick to enter the final <tab>, I'd meant to add a space. A trailing backslash is effectively removed by the tab completion matching code but it remains on the display. This confuses the code to display case-preserved filenames. Upstream BusyBox just ends up with a spurious backslash in the name. Bash rewrites the command line to remove the surplus backslash. Fix the issue in busybox-w32 by leaving the backslash in the name, even for matching purposes. This will never result in a match, thus affording the user a change to correct their mistake.

* | winansi: fix ansi emulationRon Yorston2021-03-051-12/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following commands (reported in GitHub issue #201): printf "\033[38;2;255;0;0mX\033[m\n" printf "\033[38;2;255;0;0m;\033[m\n" produce different results. The first correctly displays a red 'X' while the second incorrectly displays a white ';'. The problem is that process_24bit() overruns the extent of the escape sequence. As a result the loop in process_escape() which handles 'ESC[...m' sequences sees the ';' in the text as a continuation of the escape sequence. Fix this by: - reworking process_24bit() so that the overrun is avoided; - changing the test in the loop in process_escape() so that even if an overrun happens it stops processing at the end of the escape sequence. Also, save a few bytes by replacing '++str' with 'str + 1' in a few places.
* | Work around GNU Make bug involving shell built-insChristopher Wellons2021-03-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The workaround for MSYS2 in 475c111 interacts badly with a long-standing bug in GNU Make where it avoids spawning a shell when it believes it can handle a command itself as a sort of Bourne shell emulation. Since "command" is typically implemented as a special shell built-in and not an actual program, and GNU Make does not implement this built-in in its Bourne shell emulation, GNU Make's shell function fails to invoke it properly, resulting in an error: make: command: Command not found One work-around is to set a custom shell that is not "/bin/sh" so that GNU Make does not assume any particular shell semantics. For instance: make SHELL=dash A second work-around is to use a shell feature not implemented by GNU Make, such as redirection or variable assignment (this patch), causing it to spawn an actual shell to handle the shell command.

| | | | | | | | | | | | Restore the '--install -s' option which allows BusyBox to install symbolic links. Of course, this will only work if the user has permission to create symlinks.
* | ash: correctly identify applet in getopt() error messagesRon Yorston2021-03-021-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | With the default configuration most applets are run from the shell via run_noexec_applet_and_exit(). If the applet runs getopt() and an error is detected the message takes the form: sh: unknown option -- q This happens because mingw-w64's implementation of getopt() uses the global variable __argv[0] as the name of the program. Avoid the misleading message by setting __argv[0] as appropriate.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | musl libc's mallocng free() may modify errno if kernel does not support MADV_FREE which causes echo to echo with error when it shouldn't. Future versions of POSIX[1] will require that free() leaves errno unmodified but til then, do not rely free() implementation.

| * lineedit: support empty PATH entries in tab completionRon Yorston2021-02-231-6/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Zero-length path prefixes can be specified in PATH as a leading or trailing colon or two adjacent colons. POSIX says that the use of zero-length prefixes to refer to the current directory is a legacy feature. Nonetheless the shells in BusyBox respect this feature, as does 'which'. Tab-completion of executables using PATH should support this too. function old new delta complete_cmd_dir_file 934 931 -3 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-3) Total: -3 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
