2014-12-07libarchive: add capability to unpack to mem.bufferDenys Vlasenko
The performance and number of processes for a "depmod -a" with gzipped modules was abysmal. This patch adds a code path without fork, benefiting all users of xmalloc_open_zipped_read_close. "modinfo radeon.ko.gz", a single-file reader, got 30% faster. "depmod -a", which used to fork over 800 times, got 20% faster.

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>

BusyBox sendmail uses the NIS domain name instead which, in many cases, is likely to be the default "(none)". [vda: yes, I checked my machine and its uts.domainname was indeed "(none)"] Using the host name is more likely to satisfy the intent of the RFC while allowing the otherwise unused safe_getdomainname function to be removed.

2012-02-09Make unix (local) sockets work without IPv6 enabledJonh Wendell
The xsocket_type() function had an optional "family" argument that was enabled only if IPv6 is enabled. In the case of the function was called with a valid AF_UNIX argument, and IPv6 is disabled, this argument was silently ignored. This patch makes the "family" argument mandatory, while keeping the old behavior i.e., if AF_UNSPEC is passed, we try first IPv6 (if it's enabled) and fallback to IPv4. Also I changed all callers of xsocket_type() to reflect its new interface. Signed-off-by: Jonh Wendell <jonh.wendell@vexcorp.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
