2021-10-07find: Unify time comparisonsIsmael Luceno
Split the common part into a function, to be reused. The tail call is optimized, meaning now mmin/mtime just prepare arguments and jump into the common code, thus near zero overhead. This reduces code size slightly, e.g. on x86_64: text data bss dec hex filename 4806 0 0 4806 12c6 findutils/find.o.orig 4782 0 0 4782 12ae findutils/find.o Of course, the savings are even greater when implementing atime/ctime variants.

From POSIX.1-2008: The pattern_list's value shall consist of one or more patterns separated by <newline> characters; As such, given patterns need to be split at newline characters. Without doing so, busybox grep will interpret the newline as part of the pattern which is not in accordance with POSIX.

2020-04-29xargs: restore correct behaviour of -n optionRon Yorston
Since commit 1ff7002b1 (xargs: fix handling of quoted arguments, closes 11441) the -n option hasn't worked properly: $ echo 1 2 3 | xargs -n 1 echo 1 2 3 $ Because state is now remembered between calls to process_stdin() it's necessary to update the state before any premature return.

2020-01-29xargs: fix handling of quoted arguments, closes 11441Ron Yorston

If the allowed number of characters is exceeded part way through a quoted argument the next call to process_stdin() incorrectly treats the terminating quote as a starting quote, thus quoting all of the argument separators. function old new delta process_stdin 274 303 +29 xargs_main 731 745 +14 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 2/0 up/down: 43/0) Total: 43 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2019-07-02libbb: reduce the overhead of single parameter bb_error_msg() callsJames Byrne
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.

We found out that busybox -x -v is a bit broken: ari@ari-thinkpad:~/busybox$ echo ' aa bb cc' | ./busybox grep -x -e 'aa.*' -e '.*bb.*' aa bb cc ari@ari-thinkpad:~/busybox$ echo ' aa bb cc' | ./busybox grep -x -v -e 'aa.*' -e '.*bb.*' ari@ari-thinkpad:~/busybox$ echo ' aa bb cc' | ./busybox grep -x -e '.*aa.*' -e 'bb.*' aa bb cc ari@ari-thinkpad:~/busybox$ echo ' aa bb cc' | ./busybox grep -x -v -e '.*aa.*' -e 'bb.*' aa bb cc Last one is wrong. This patch fixes the issue by making sure that the variable 'found' never makes a transition from 1 to 0, as this would mean that grep previously found a match on this input line.

2017-10-31grep: skip grepping symlinks to directoriesJames Clarke
When grep is passed -r, recursive_action will treat any symlinks to directories not in the root as normal files, since it lstat's them and is therefore told they are not directories. However, file_action_grep will still try to fopen and read from them to see whether they match, which varies in behaviour across platforms. Linux will give EISDIR and thus grep will not find any matching lines, but FreeBSD will give the raw contents of the directory itself, which may match the given pattern. Also, if grep is passed -c, it will even print a count for these symlinks, even on Linux. Since this recursive_action behaviour is required for the correct functioning of other applets, such as tar, grep should handle this special case and skip any such symlinks. function old new delta file_action_grep 80 161 +81 Signed-off-by: James Clarke <jrtc27@jrtc27.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2017-08-08getopt32: remove applet_long_optionsDenys Vlasenko
FEATURE_GETOPT_LONG made dependent on LONG_OPTS. The folloving options are removed, now LONG_OPTS enables long options for affected applets: FEATURE_ENV_LONG_OPTIONS FEATURE_EXPAND_LONG_OPTIONS FEATURE_UNEXPAND_LONG_OPTIONS FEATURE_MKDIR_LONG_OPTIONS FEATURE_MV_LONG_OPTIONS FEATURE_RMDIR_LONG_OPTIONS FEATURE_ADDGROUP_LONG_OPTIONS FEATURE_ADDUSER_LONG_OPTIONS FEATURE_HWCLOCK_LONG_OPTIONS FEATURE_NSENTER_LONG_OPTS FEATURE_CHCON_LONG_OPTIONS FEATURE_RUNCON_LONG_OPTIONS They either had a small number of long options, or their long options are essential. Example: upstream addgroup and adduser have ONLY longopts, we should probably go further and get rid of non-standard short options. To this end, make addgroup and adduser "select LONG_OPTS". We had this breakage caused by us even in our own package! #if ENABLE_LONG_OPTS || !ENABLE_ADDGROUP /* We try to use --gid, not -g, because "standard" addgroup * has no short option -g, it has only long --gid. */ argv[1] = (char*)"--gid"; #else /* Breaks if system in fact does NOT use busybox addgroup */ argv[1] = (char*)"-g"; #endif xargs: its lone longopt no longer depends on DESKTOP, only on LONG_OPTS. hwclock TODO: get rid of incompatible -t, -l aliases to --systz, --localtime Shorten help texts by omitting long option when short opt alternative exists. Reduction of size comes from the fact that store of an immediate (an address of longopts) to a fixed address (global variable) is a longer insn than pushing that immediate or passing it in a register. This effect is CPU-agnostic. function old new delta getopt32 1350 22 -1328 vgetopt32 - 1318 +1318 getopt32long - 24 +24 tftpd_main 562 567 +5 scan_recursive 376 380 +4 collect_cpu 545 546 +1 date_main 1096 1095 -1 hostname_main 262 259 -3 uname_main 259 255 -4 setpriv_main 362 358 -4 rmdir_main 191 187 -4 mv_main 562 558 -4 ipcalc_main 548 544 -4 ifenslave_main 641 637 -4 gzip_main 192 188 -4 gunzip_main 77 73 -4 fsfreeze_main 81 77 -4 flock_main 318 314 -4 deluser_main 337 333 -4 cp_main 374 370 -4 chown_main 175 171 -4 applet_long_options 4 - -4 xargs_main 894 889 -5 wget_main 2540 2535 -5 udhcpc_main 2767 2762 -5 touch_main 436 431 -5 tar_main 1014 1009 -5 start_stop_daemon_main 1033 1028 -5 sed_main 682 677 -5 script_main 1082 1077 -5 run_parts_main 330 325 -5 rtcwake_main 459 454 -5 od_main 2169 2164 -5 nl_main 201 196 -5 modprobe_main 773 768 -5 mkdir_main 160 155 -5 ls_main 568 563 -5 install_main 773 768 -5 hwclock_main 411 406 -5 getopt_main 622 617 -5 fstrim_main 256 251 -5 env_main 198 193 -5 dumpleases_main 635 630 -5 dpkg_main 3991 3986 -5 diff_main 1355 1350 -5 cryptpw_main 233 228 -5 cpio_main 593 588 -5 conspy_main 1135 1130 -5 chpasswd_main 313 308 -5 adduser_main 887 882 -5 addgroup_main 416 411 -5 ftpgetput_main 351 345 -6 get_terminal_width_height 242 234 -8 expand_main 690 680 -10 static.expand_longopts 18 - -18 static.unexpand_longopts 27 - -27 mkdir_longopts 28 - -28 env_longopts 30 - -30 static.ifenslave_longopts 34 - -34 mv_longopts 46 - -46 static.rmdir_longopts 48 - -48 packed_usage 31739 31687 -52 ------------------------------------------------------------------------------ (add/remove: 2/8 grow/shrink: 3/49 up/down: 1352/-1840) Total: -488 bytes text data bss dec hex filename 915681 485 6880 923046 e15a6 busybox_old 915428 485 6876 922789 e14a5 busybox_unstripped Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
