* libbb/loop: don't try to re-use existing loop deviceKevin Wallace2015-02-071-10/+1
| | | | | | | | | | | loopinfo.lo_file_name is not enough to uniquely identify a file on a system with multiple mount namespaces. We could conceivably change this to dedup on (lo_rdevice, lo_inode), but, as the comment above the deleted code notes, this whole approach of reusing devices is racy anyway, so it seems better to stop doing it entirely.

* libbb: use sendfile() to copy data between file descriptorsBartosz Golaszewski2014-11-271-31/+56
| | | | | | | | | | | | | | | | | | | | | | | 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>
* libbb: use ARG_MAX for bb_arg_max() only if it's 60k+Denys Vlasenko2014-11-261-1/+1
| | | | | | | | | | | | | | | | | 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>
