gcc 11.2.1 complains that the tar header checksum might overflow the checksum field. It won't and using an unsigned int for the calculation seems to convince the compiler too. Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2021-08-22shuf: speed-up when limited output is requestedRon Yorston
A user noted that the following command was slower than they expected: busybox shuf -i "1500000000-$(date +%s)" -n 5 At time of writing the range contains 128 million values. On my system this takes 7.7s whereas 'shuf' from coreutils takes a handful of milliseconds. Optimise BusyBox 'shuf' for cases where -n is specified by stopping shuffling once the required number of lines have been processed. On my system the time for the example is reduced to 0.4s. function old new delta shuf_main 520 540 +20 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/0 up/down: 20/0) Total: 20 bytes v2: Code shrink. Since outlines <= numlines: - the loop in shuffle_lines() only needs to test the value of outlines; - shuffle_lines() can be called unconditionally.

2021-08-22vi: code shrink print_literal()Ron Yorston
Simplify the function print_literal() which is used to format a string that may contain unprintable characters or control characters. - Unprintable characters were being displayed in normal text rather than the bold used for the rest of the message. This doesn't seem particularly helpful and it upsets the calculation of the width of the message in show_status_line(). Use '?' rather than '.' for unprintable characters. - Newlines in the string were displayed as both '^J' and '$', which is somewhat redundant. function old new delta not_implemented 199 108 -91 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-91) Total: -91 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2021-08-22vi: searches in colon commands should wrapRon Yorston
The '/' and '?' search commands wrap to the other end of the buffer if the search target isn't found. When searches are used to specify addresses in colon commands they should do the same. (In traditional vi and vim this behaviour is controlled by the 'wrapscan' option. BusyBox vi doesn't have this option and always uses the default behaviour.) function old new delta colon 4033 4077 +44 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/0 up/down: 44/0) Total: 44 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2021-08-22rev: correct output for long input linesRon Yorston
The input buffer is initialised to a reasonable size and extended if necessary. When this happened the offset into the buffer wasn't reset to zero so subsequent lines were appended to the long line.

2021-07-13vi: allow delimiter in ':s' to be escapedRon Yorston
When regular expressions are allowed in search commands it becomes possible to escape the delimiter in search/replace commands. For example, this command will replace '/abc' with '/abc/': :s/\/abc/\/abc\//g The code to split the command into 'find' and 'replace' strings should allow for this possibility. VI_REGEX_SEARCH isn't enabled by default. When it is: function old new delta strchr_backslash - 38 +38 colon 4378 4373 -5 ------------------------------------------------------------------------------ (add/remove: 1/0 grow/shrink: 0/1 up/down: 38/-5) Total: 33 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2021-07-13vi: allow regular expressions in ':s' commandsDenys Vlasenko
BusyBox vi has never supported the use of regular expressions in search/replace (':s') commands. Implement this using GNU regex when VI_REGEX_SEARCH is enabled. The implementation: - uses basic regular expressions, to match those used in the search command; - only supports substitution of back references ('\0' - '\9') in the replacement string. Any other character following a backslash is treated as that literal character. VI_REGEX_SEARCH isn't enabled in the default build. In that case: function old new delta colon 4036 4033 -3 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-3) Total: -3 bytes When VI_REGEX_SEARCH is enabled: function old new delta colon 4036 4378 +342 .rodata 108207 108229 +22 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 2/0 up/down: 364/0) Total: 364 bytes v2: Rebase.

2021-07-13vi: improve handling of anchored searchesRon Yorston
Suppose we search for a git conflict marker '<<<<<<< HEAD' using the command '/^<<<'. Using 'n' to go to the next match finds '<<<' on the current line, apparently ignoring the '^' anchor. Set a flag in the compiled regular expression to indicate that the start of the string should not be considered a beginning-of-line anchor. An exception has to be made when the search starts from the beginning of the file. Make a similar change for end-of-line anchors. This doesn't affect a default build with VI_REGEX_SEARCH disabled.
