2021-09-30awk: fix read beyond end of bufferRon Yorston
Commit 7d06d6e18 (awk: fix printf %%) can cause awk printf to read beyond the end of a strduped buffer: 2349 while (*f && *f != '%') 2350 f++; 2351 c = *++f; If the loop terminates because a NUL character is detected the character after the NUL is read. This can result in failures depending on the value of that character. function old new delta awk_printf 672 665 -7 Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2021-09-30awk: 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>
2021-09-30ash: 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>

2021-07-13vi: 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.

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.

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.

2021-07-13vi: use basic regular expressions for searchRon Yorston
Both traditional vi and vim use basic regular expressions for search. Also, they don't allow matches to extend across line endings. Thus with the file: 123 234 the search '/2.*4$' should find the second '2', not the first. Make BusyBox vi do the same.

Commit 7b93e317c (vi: enable 'dG' command. Closes 11801) allowed 'G' to be used as a range specifier for change/yank/delete operations. Add similar support for 'gg'.
