Copyright © 1994 David Burren. It is licensed under a BSD license.
The implementation of blowfish crypt (src/misc/crypt_blowfish.c) was
originally written by Solar Designer and placed into the public

in jurisdictions that may not recognize the public domain.

replace heap sort with smoothsort implementation by Valentin Ochs Smoothsort is an adaptive variant of heapsort. This version was written by Valentin Ochs (apo) specifically for inclusion in musl. I worked with him to get it working in O(1) memory usage even with giant array element widths, and to optimize it heavily for size and speed. It's still roughly 4 times as large as the old heap sort implementation, but roughly 20 times faster given an almost-sorted array of 1M elements (20 being the base-2 log of 1M), i.e. it really does reduce O(n log n) to O(n) in the mostly-sorted case. It's still somewhat slower than glibc's Introsort for random input, but now considerably faster than glibc when the input is already sorted, or mostly sorted.

build system and code conventions during upstream integration. It is

The decision to exclude such comments is intentional, as it should be
possible to carry around the complete source code on tiny storage
media. All public header files (include/*) should be treated as Public
Domain as they intentionally contain no content which can be covered
by copyright. Some source modules may fall in this category as well.
If you believe that a file is so trivial that it should be in the
Public Domain, please contact me and, if I agree, I will explicitly
release it from copyright.
explicitly release crt/* to the public domain
2011-02-14 04:32:01 +00:00
The following files are trivial, in my opinion not copyrightable in
the first place, and hereby explicitly released to the Public Domain:
All public headers: include/*
Startup files: crt/*
