2014-12-15lineedit: don't block when looking for escape sequence in vi-modeRon Yorston
In vi-mode lineedit tries to detect some escape sequences. After the ESC it reads the next character to check for certain values. This read should have a timeout or a user-entered ESC to switch to command mode doesn't properly handle the next character.

2014-11-27libbb: use sendfile() to copy data between file descriptorsBartosz Golaszewski
Busybox already uses sendfile in httpd. This patch proposes to use it globally to copy data between file descriptors. It speeds up the copying on slow systems a lot - below are the times needed to copy a 450Mb file with and without this option enabled on a BeagleBone Black: sendfile: user 0m0.000s sys 0m8.170s read/write 4k: user 0m0.470s sys 0m16.300s function old new delta bb_full_fd_action 394 474 +80 Signed-off-by: Bartosz Golaszewski <bartekgola@gmail.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
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>

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>.
