2023-12-31awk: fix handling of empty fieldsDenys Vlasenko
Patch by M Rubon <rubonmtz@gmail.com>: Busybox awk handles references to empty (not provided in the input) fields differently during the first line of input, as compared to subsequent lines. $ (echo a ; echo b) | awk '$2 != 0' #wrong b No field $2 value is provided in the input. When awk references field $2 for the "a" line, it is seen to have a different behaviour than when it is referenced for the "b" line. Problem in BusyBox v1.36.1 embedded in OpenWrt 23.05.0 Same problem also in 21.02 versions of OpenWrt Same problem in BusyBox v1.37.0.git I get the correct expected output from Ubuntu gawk and Debian mawk, and from my fix. will@dev:~$ (echo a ; echo b) | awk '$2 != 0' #correct a b will@dev:~/busybox$ (echo a ; echo b ) | ./busybox awk '$2 != 0' #fixed a b I built and poked into the source code at editors/awk.c The function fsrealloc(int size) is core to allocating, initializing, reallocating, and reinitializing fields, both real input line fields and imaginary fields that the script references but do not exist in the input. When fsrealloc() needs more field space than it has previously allocated, it initializes those new fields differently than how they are later reinitialized for the next input line. This works fine for fields defined in the input, like $1, but does not work the first time when there is no input for that field (e.g. field $99) My one-line fix simply makes the initialization and clrvar() reinitialization use the same value for .type. I am not sure if there are regression tests to run, but I have not done those. I'm not sure if I understand why clrvar() is not setting .type to a default constant value, but in any case I have left that untouched. function old new delta ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 0/0 up/down: 0/0) Total: 0 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2021-12-25sed: do not ignore 'g' modifier when match starts with ^Dominique Martinet
It is perfectly valid to start a regex with ^ and have other patterns with \| that can match more than once, e.g. the following example should print ca, as illustrated with gnu sed: $ echo 'abca' | sed -e 's/^a\|b//g' ca busybox before patch: $ echo 'abca' | busybox sed -e 's/^a\|b//g' bca busybox after patch: $ echo 'abca' | ./busybox sed -e 's/^a\|b//g' ca regcomp handles ^ perfectly well as illustrated with the second 'a' that did not match in the example, we ca leave the non-repeating to it if appropriate. The check had been added before using regcomp and was required at the time (f36635cec6da) but no longer makes sense now.

2021-12-17printf: allow 0 as a flag and allow multiple flagsRon Yorston
The '%' character in a format specification may be followed by one or more flags from the list "+- #0". BusyBox printf didn't support the '0' flag or allow multiple flags to be provided. As a result the formats '%0*d' and '%0 d' were considered to be invalid. The lack of support for '0' was pointed out by Andrew Snyder on the musl mailing list: https://www.openwall.com/lists/musl/2021/12/14/2 function old new delta printf_main 860 891 +31 .rodata 99281 99282 +1 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 2/0 up/down: 32/0) Total: 32 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2021-10-09libbb: better coreutils compatibility for realpathRon Yorston
Add some tests which coreutils realpath pass but BusyBox realpath fails (bar one). Adjust xmalloc_realpath_coreutils() so the tests pass: - Expand symbolic links before testing whether the last path component exists. - When the link target is a relative path canonicalize it by passing it through xmalloc_realpath_coreutils() as already happens for absolute paths. - Ignore trailing slashes when finding the last path component and correctly handle the case where the only slash is at the start of the path. This requires ignoring superfluous leading slashes. - Undo all changes to the path so error messages from the caller show the original filename. function old new delta xmalloc_realpath_coreutils 214 313 +99 Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

Allow ISO 8601 style dates to include a timezone offset. Like the '@' format these dates aren't relative to the user's current timezone and shouldn't be subject to DST adjustment. - The implementation uses the strptime() '%z' format specifier.

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.
