From 036585a911a5fe6c2cd77b808dd9150500f37272 Mon Sep 17 00:00:00 2001 From: Denys Vlasenko Date: Tue, 8 Aug 2017 16:38:18 +0200 Subject: getopt32: remove applet_long_options 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 --- debianutils/start_stop_daemon.c | 12 +++++++----- 1 file changed, 7 insertions(+), 5 deletions(-) (limited to 'debianutils/start_stop_daemon.c') diff --git a/debianutils/start_stop_daemon.c b/debianutils/start_stop_daemon.c index 9effdc8..45c277a 100644 --- a/debianutils/start_stop_daemon.c +++ b/debianutils/start_stop_daemon.c @@ -426,6 +426,11 @@ static const char start_stop_daemon_longopts[] ALIGN1 = "retry\0" Required_argument "R" # endif ; +# define GETOPT32 getopt32long +# define LONGOPTS start_stop_daemon_longopts, +#else +# define GETOPT32 getopt32 +# define LONGOPTS #endif int start_stop_daemon_main(int argc, char **argv) MAIN_EXTERNALLY_VISIBLE; @@ -446,10 +451,6 @@ int start_stop_daemon_main(int argc UNUSED_PARAM, char **argv) INIT_G(); -#if ENABLE_FEATURE_START_STOP_DAEMON_LONG_OPTIONS - applet_long_options = start_stop_daemon_longopts; -#endif - /* -K or -S is required; they are mutually exclusive */ /* -p is required if -m is given */ /* -xpun (at least one) is required if -K is given */ @@ -457,8 +458,9 @@ int start_stop_daemon_main(int argc UNUSED_PARAM, char **argv) /* -q turns off -v */ opt_complementary = "K:S:K--S:S--K:m?p:K?xpun:S?xa" IF_FEATURE_START_STOP_DAEMON_FANCY("q-v"); - opt = getopt32(argv, "KSbqtma:n:s:u:c:x:p:" + opt = GETOPT32(argv, "KSbqtma:n:s:u:c:x:p:" IF_FEATURE_START_STOP_DAEMON_FANCY("ovN:R:"), + LONGOPTS &startas, &cmdname, &signame, &userspec, &chuid, &execname, &pidfile IF_FEATURE_START_STOP_DAEMON_FANCY(,&opt_N) /* We accept and ignore -R / --retry */ -- cgit v1.1
