* Revert r330897:Eitan Adler2018-03-2972-160/+16
| | | | | | | | | | | | | | | | | | | | This was intended to be a non-functional change. It wasn't. The commit message was thus wrong. In addition it broke arm, and merged crypto related code. Revert with prejudice. This revert skips files touched in r316370 since that commit was since MFCed. This revert also skips files that require $FreeBSD$ property changes.

The change in performance over a locally mounted UFS filesystem was negligible in my testing, but this may more positively impact other filesystems like NFS. LIBC_SRCTOP was left alone so Juniper (and other users) can continue to manipulate lib/libc/Makefile (and other Makefile.inc's under lib/libc) as include Makefiles with custom options.

* collate: Fix expansion substitions (broken upstream too)Baptiste Daroussin2015-10-231-40/+59
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

|/ | | | | | | | | | | | | | | | | | | | | | | | | packed LC_COLLATE binary formats. These were generated with the colldef tool, but the new LC_COLLATE files are going to be generated by the new localedef tool using CLDR POSIX files as input. The BSD-flavored version of localedef identifies the format as "BSD 1.0". Any LC_COLLATE file with a different version will simply not be loaded, and all LC* categories will get set to "C" (aka "POSIX") locale. This work is based off of Nexenta's contribution to Illumos. The integration with xlocale is John Marino's work for Dragonfly. The following commits will enable localedef tool, disable the colldef tool, add generated colldef directory, and finally remove colldef from base. The only difference with Dragonfly are: - a few fixes to build with clang - And identification of the flavor as "BSD 1.0" instead of "Dragonfly 4.4" Obtained from: Dragonfly Notes: svn path=/projects/collation/; revision=286430

* libc: Always use our own copy of sys_errlist and sys_nerr (.so only).Jilles Tjoelker2013-08-311-3/+5
| | | | | | | | | | | | | | | | | | This ensures strerror() and friends continue to work correctly even if a (non-PIE) executable linked against an older libc imports sys_errlist (which causes sys_errlist to refer to the executable's copy with a size fixed when that executable was linked). The executable's use of sys_errlist remains broken because it uses the current value of sys_nerr and may access past the bounds of the array. Different from the message "Using sys_errlist from executables is not ABI-stable" on freebsd-arch, this change does not affect the static library. There seems no reason to prevent overriding the error messages in the static library. Notes: svn path=/head/; revision=255108
