2021-09-05awk: fix printf %%Daniel Thau
A refactor of the awk printf code in e2e3802987266c98df0efdf40ad5da4b07df0113 appears to have broken the printf interpretation of two percent signs, which normally outputs only one percent sign. The patch below brings busybox awk printf behavior back into alignment with the pre-e2e380 behavior, the busybox printf util, and other common (awk and non-awk) printf implementations. function old new delta awk_printf 626 672 +46 Signed-off-by: Daniel Thau <danthau at bedrocklinux.org> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2021-09-02ash: regressions in process substitutionRon Yorston
Stacy Harper reports that this script: test() { . /tmp/bb_test; } echo "export TEST=foo" >/tmp/bb_test test 2>/dev/null echo "$TEST" correctly prints 'foo' in BusyBox 1.33 but hangs in 1.34. Bisection suggested the problem was caused by commit a1b0d3856 (ash: add process substitution in bash-compatibility mode). Removing the call to unwindredir() in cmdloop() introduced in that commit makes the script work again. Additionally, these examples of process substitution: while true; do cat <(echo hi); done f() { while true; do cat <(echo hi); done } f result in running out of file descriptors. This is a regression from v5 of the process substitution patch caused by changes to evalcommand() not being transferred to v6. function old new delta static.pushredir - 99 +99 evalcommand 1729 1750 +21 exitreset 69 86 +17 cmdloop 372 365 -7 unwindredir 28 - -28 pushredir 112 - -112 ------------------------------------------------------------------------------ (add/remove: 1/2 grow/shrink: 2/1 up/down: 137/-147) Total: -10 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2021-08-29vi: further changes to colon addressesRon Yorston
Improved error messages: - specify when a search fails or a mark isn't set; - warn when line addresses are out of range or when a range of lines is reversed. Addresses are limited to the number of lines in the file so a command like ':2000000000' (go to the two billionth line) no longer causes a long pause. Improved vi compatibility of '+' and '-' operators that aren't followed immediately by a number: :4+++= 7 :3-2= 1 :3 - 2= 4 (yes, really!) In a command like ':,$' the empty address before the separator now correctly refers to the current line. (The similar case ':1,' was already being handled.)

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
