libc: Purge unneeded cdefs.h

2023-11-27T04:20:09Z

These sys/cdefs.h are not needed. Purge them. They are mostly left-over from the $FreeBSD$ removal. A few in libc are still required for macros that cdefs.h defines. Keep those.

spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSD

The SPDX folks have obsoleted the BSD-2-Clause-FreeBSD identifier. Catch up to that fact and revert to their recommended match of BSD-2-Clause. Discussed with: pfg MFC After: 3 days Sponsored by: Netflix

libc: drop "All rights reserved" from Foundation copyrights

2022-08-04T20:57:50Z

This has already been done for most files that have the Foundation as the only listed copyright holder. Do it now for files that list multiple copyright holders, but have the Foundation copyright in its own section. Sponsored by: The FreeBSD Foundation

libc: further adoption of SPDX licensing ID tags.

2017-11-25T17:12:48Z

Mainly focus on files that use BSD 2-Clause license, however the tool I was using mis-identified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

collate: Fix expansion substitions (broken upstream too)

2015-10-23T23:24:03Z

Through testing, the user noted that some Cyrillic characters were not sorting correctly, and this was confirmed. After extensive testing and review, the localedef tool was eliminated as the culprit. The sustitutions were encoded correctly in LC_COLLATE. The error was mainly in wcscoll where character expansions were mishandled. The main directive pass routines had to be written to go back for a new collation value when the "state" variable was set. Before pointers were being advanced, the second lookup was gettting applied to the wrong character, etc. The "eat expansion codes" section on collate.c also had a bug. Later own, the "state" variable logic was changed to only set if next code was greater than zero (rather than >= 0). Some additional cleanups got captured from previous work: 1) The previous commit moved the binary search comment from the correct location to a wrong location because it's wrong upstream in Illumos. The comment has little value so I just removed it. 2) Don't check if pointers are null before freeing, this is redundant as free() handles null pointers. 3) The two binary search trees were standardized wrt initialization 4) On the binary search trees, a negative "high" exits rather than checking the table count again.
