| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 0068ce2fa (cut: add toybox-compatible options -O OUTSEP, -D, -F LIST) added detection of reversed ranges. Further improvements are possible. - The test for reversed ranges compared the start after it had been decremented with the end before decrement. It thus missed ranges of the form 2-1. - Zero isn't a valid start value for a range. (Nor is it a valid end value, but that's caught by the test for a reversed range.) - The code if (!*ltok) e = INT_MAX; duplicates a check that's already been made. - Display the actual range in the error message to make it easier to find which range was at fault. function old new delta .rodata 100273 100287 +14 cut_main 1239 1237 -2 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/1 up/down: 14/-2) Total: 12 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
* cut: fix "-s" flag to omit blank linesColin McAllister2024-12-101-5/+15
| | | | | | | | | | | | | | | | | | Using cut with the delimiter flag ("-d") with the "-s" flag to only output lines containing the delimiter will print blank lines. This is deviant behavior from cut provided by GNU Coreutils. Blank lines should be omitted if "-s" is used with "-d". This change introduces a somewhat naiive, yet efficient solution, where line length is checked before looping though bytes. If line length is zero and the "-s" flag is used, the code will jump to parsing the next line to avoid printing a newline character. function old new delta cut_main 1196 1185 -11 Signed-off-by: Colin McAllister <colinmca242@gmail.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

* libbb: reduce the overhead of single parameter bb_error_msg() callsJames Byrne2019-07-021-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Back in 2007, commit 0c97c9d43707 ("'simple' error message functions by Loic Grenie") introduced bb_simple_perror_msg() to allow for a lower overhead call to bb_perror_msg() when only a string was being printed with no parameters. This saves space for some CPU architectures because it avoids the overhead of a call to a variadic function. However there has never been a simple version of bb_error_msg(), and since 2007 many new calls to bb_perror_msg() have been added that only take a single parameter and so could have been using bb_simple_perror_message(). This changeset introduces 'simple' versions of bb_info_msg(), bb_error_msg(), bb_error_msg_and_die(), bb_herror_msg() and bb_herror_msg_and_die(), and replaces all calls that only take a single parameter, or use something like ("%s", arg), with calls to the corresponding 'simple' version. Since it is likely that single parameter calls to the variadic functions may be accidentally reintroduced in the future a new debugging config option WARN_SIMPLE_MSG has been introduced. This uses some macro magic which will cause any such calls to generate a warning, but this is turned off by default to avoid use of the unpleasant macros in normal circumstances. This is a large changeset due to the number of calls that have been replaced. The only files that contain changes other than simple substitution of function calls are libbb.h, libbb/herror_msg.c, libbb/verror_msg.c and libbb/xfuncs_printf.c. In miscutils/devfsd.c, networking/udhcp/common.h and util-linux/mdev.c additonal macros have been added for logging so that single parameter and multiple parameter logging variants exist. The amount of space saved varies considerably by architecture, and was found to be as follows (for 'defconfig' using GCC 7.4): Arm: -92 bytes MIPS: -52 bytes PPC: -1836 bytes x86_64: -938 bytes Note that for the MIPS architecture only an exception had to be made disabling the 'simple' calls for 'udhcp' (in networking/udhcp/common.h) because it made these files larger on MIPS.
