2016-02-01Fix compiling with musl's utmp stubsKylie McClain
This patch fixes compiling busybox with FEATURE_UTMP and _WTMP enabled. musl, while not really support utmp/wtmp, provides stub functions, as well as variables such as _PATH_UTMP, so that programs using utmp or wtmp can still compile fine. My reasoning for this patch is that on Exherbo, I'm currently trying to get us to be able to use the same busybox config file for both glibc and musl systems, using utmp/wtmp on systems that support it, and using the stubs on musl without needing two different configs. As of latest musl git, it provides all utmp functions needed; 1.1.12 doesn't, but I sent a patch to Rich to add the utmp{,x}name functions expected to exist, which was merged into musl upstream.

2014-11-26libbb: use ARG_MAX for bb_arg_max() only if it's 60k+Denys Vlasenko
Sometimes ARG_MAX is small (like 32k) yet sysconf(_SC_ARG_MAX) is big, and people prefer using the bigger value. OTOH, with sufficiently large ARG_MAX, further wins from sysconf(_SC_ARG_MAX) being bigger are exponentially smaller: you can see 4 times fewer fork+execs when you run find, but when each execed process already takes a thousand parameters it's likely execution time is dominated by what that process does with each parameter. Thus, with this change ARG_MAX is used if it's sufficiently big, otherwise sysconf(_SC_ARG_MAX) is used. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2014-06-30Rename INIT_LAST to INIT_FUNC to avoid confusionBartosz Golaszewski
We don't have an INIT_FIRST, so let's rename INIT_LAST to INIT_FUNC to imply that the function is called at program start-up. Also: the priority argument for __attribute__((constructor)) isn't used, so let's remove it.

2014-06-22find: use sysconf(_SC_ARG_MAX) to determine the command-line size limitDenys Vlasenko
The find utility uses a hardcoded value of 32 * 1024 as the limit of the command-line length when calling 'find -exec ... {} +'. This results in over 4 times more execve() calls than in coreutils' find. This patch uses the limit defined in system headers. Based on the patch by Bartosz Golaszewski <bartekgola@gmail.com>.
