2021-09-17date,touch: allow timezone offsets in datesRon Yorston
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. This an extension which may not be available so the use of timezones is a configuration option. - The 'touch' applet has been updated to respect whether DST adjustment is required, matching 'date'. function old new delta parse_datestr 624 730 +106 static.fmt_str 106 136 +30 touch_main 388 392 +4 date_main 818 819 +1 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 4/0 up/down: 141/0) Total: 141 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2021-04-13touch: switch to using utimensat() and futimens()Denys Vlasenko
This patch changes the functions used to update timestamps in touch. Before, utimes() and lutimes() were used, which had certain disadvantages. They are unable to handle nanosecond timestamps, and implementations of certain features like -a and -m require running stat() in a loop. Almost all implementations of utimes() and lutimes() are wrappers for utimensat(), this is the case for glibc, ulibc and musl libc. function old new delta __futimens_time64 - 24 +24 __lutimes_time64 80 - -80 touch_main 539 456 -83 ------------------------------------------------------------------------------ (add/remove: 2/2 grow/shrink: 0/1 up/down: 24/-163) Total: -139 bytes Signed-off-by: urmum-69 <urmum69@snopyta.org> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2021-04-12touch: remove unneeded GETOPT32 definesXabier Oneca
Long options handling (getopt32 vs getopt32long) is done in libbb.h, no need to care here of the same logic. This cleans the code a bit. Also, --no-create was grouped as a SUSv3 option, where as the short -c was not. Even if it is part of SUS, leave it out as was the short option. v2: Fix for disabled ENABLE_LONG_OPTS. getopt32long does not like IF_FEATURE_xxx() style conditionals... :/ Signed-off-by: Xabier Oneca <xoneca@gmail.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>
