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>

2021-02-23echo: do not assume that free() leaves errno unmodifiedNatanael Copa
musl libc's mallocng free() may modify errno if kernel does not support MADV_FREE which causes echo to echo with error when it shouldn't. Future versions of POSIX[1] will require that free() leaves errno unmodified but til then, do not rely free() implementation.

USER[:[GRP]] FILE... $ ./busybox.nosuid chgrp Usage: chgrp [-RhLHP]... GROUP FILE... $ ./busybox.nosuid chgrp -H group dummy chgrp: invalid option -- 'H' Usage: chgrp [-RhLHP]... GROUP FILE... The chgrp is now a wrapper of chown, so the recognized options shall be the same. This is introduced by 34425389e09353a8dacdd6b23a62553f699c544c I would expect the correct behavior shall be the same as chown.

2019-10-08date: Use 64 prefix syscall if we have toAlistair Francis
Some 32-bit architectures no longer have the 32-bit time_t syscalls. Instead they have suffixed syscalls that returns a 64-bit time_t. If the architecture doesn't have the non-suffixed syscall and is using a 64-bit time_t let's use the suffixed syscall instead. This fixes build issues when building for RISC-V 32-bit with 5.1+ kernel headers. If an architecture only supports the suffixed syscalls, but is still using a 32-bit time_t fall back to the libc call.
