* More consistently put remarks about the less useful LC_* categoties,schwarze2019-05-162-14/+26
| | | | | | i.e. those other than LC_CTYPE, into the CAVEATS section, and standardize wording somewhat. OK jmc@

* Improve the description of locale dependency:schwarze2019-01-182-14/+20
| | | | | | | | * mention LC_COLLATE; * clarify that all these functions are infested, including the *_l() versions; * avoid ENVIRONMENT, these functions don't inspect it; * and point to the C library functions that change the locale. OK millert@
* As per POSIX, when str{,r}chr is comparing it should convert c to a char.martijn2018-10-014-8/+10
| | | | | | | | | | The C implementation of str{,r}chr are not linked to the build, because assembly implementations are used, but change to code for easier reference. At least the i386 and amd64 are checked and seem to do the correct thing. Found thanks to the csh any/strchr change. minor pointers and OK millert@
* Add a missing header when compiling with -DDEBUGdenis2018-04-301-1/+5
| | | | | | With advice from jca@ OK jca@ millert@
* Instead of trying to handle ffs() with the normal rename-mark-hidden-and-aliasguenther2018-01-181-2/+1
| | | | | | | dance, mark it protected. This works better for both gcc and clang: gcc blocks overriding of internal calls, while clang permits inlining again. ok otto@
* clang doesn't propagate attributes like "asm labels" and "visibility(hidden)"guenther2017-11-293-6/+6
| | | | | | | | | to builtins like mem{set,cpy,move} and __stack_smash_handler. So, when building with clang, instead mark those as protected visibility to get rid of the PLT relocations. We can't take the address of them then, but that's ok: it's a build-time error not a run-time error. ok kettenis@
* GNU ld has prefixed the contents of .gnu.warning.SYMBOL sectionstb2017-11-285-10/+10
| | | | | | | | with "warning: " since 2003, so the messages themselves need not contain the prefix anymore. From Scott Cheloha ok jca, deraadt

* New POSIX xlocale implementation written from scratch.libressl-v2.6.1schwarze2017-09-0511-96/+396
| | | | | | | | | | | | Complete in the sense that all POSIX *locale(3) and *_l(3) functions are included, but in OpenBSD, we of course only really care about LC_CTYPE and we only support ASCII and UTF-8. With important help from kettenis@, guenther@, and jca@. Repeated testing in ports bulk builds by naddy@. Additional testing by jca@, sebastia@, dcoppa@, and others. OK kettenis@ dcoppa@, and guenther@ on an earlier version. Riding guenther@'s libc/librthread major bump.

* New strstr() implementation from musl libc by Rich Felker. Thismillert2017-04-121-44/+180
| | | | | | | | version uses the two-way string matching algorithm and is faster than the old implementation. With this change, ports that check for strstr having linear complexity time strstr will no longer replace the libc strstr with a private version. OK deraadt@ espie@
* the referred to EXAMPLES section is now in strncpy(3);jmc2016-11-121-3/+3
| | | | | | issue reported by scott cheloha ok otto
* Remove the save_errno dance inside strerror_r(3). It is from thebluhm2016-10-191-5/+3
| | | | | time when we had national language support. OK millert@
* Roll back uintptr_t cast changes after discussions with tedu, otto anddtucker2016-10-163-24/+7
| | | | | | | | | | | | | others. C11 6.5.6.9 says: When two pointers are subtracted, both shall point to elements of the same array object, or one past the last element of the array object; the result is the difference of the subscripts of the two array elements. In these cases the objects are arrays of char so the result is defined, and we believe that the report is based on a compiler incorrectly trapping on defined behaviour.
* Cast pointers to uintptr_t to avoid potential signedness errors.dtucker2016-10-143-7/+24

* The destination string is declared as "s" but referred to as "dst"millert2016-05-261-5/+5
| | | | | in some cases. Be consistent and use "dst" everywhere like for strlcat(3) and strncat(3). From Tim Kuijsten.

* for some time now mandoc has not required MLINKS to functionjmc2016-03-301-21/+1
| | | | | | | | | | | | correctly - logically complete that now by removing MLINKS from base; authors need only to ensure there is an entry in NAME for any function/ util being added. MLINKS will still work, and remain for perl to ease upgrades; ok nicm (curses) bcook (ssl) ok schwarze, who provided a lot of feedback and assistance ok tb natano jung

* The only thing that was translated into multiple languages in OpenBSDbluhm2015-10-251-23/+1
| | | | | | | | | are the errno messages and signal names. Everything else is in English. We are not planning to translate more text. Running a mixed system with less than 1% of the text in native language makes no sense. So remove the NLS support from libc messages. The catopen(3) functions stay as they are. OK stsp@ mpi@

| | | | | | | | | | | | wrapper .h files and asm labels to let internal calls resolve directly and not be overridable or use the PLT. Then, apply that framework to most of the functions in stdio.h, string.h, err.h, and wchar.h. Delete the should-have-been-hidden-all-along _v?(err|warn)[cx]? symbols while here. tests clean on i386, amd64, sparc64, powerpc, and mips64 naming feedback from kettenis@ and millert@ ok kettenis@
