* Only reallocate the buffer to fit for medium-size allocations wheremillert2017-03-161-9/+14
| | | | | we expanded the buffer to a single page. The final realloc() can be expensive for large buffers and is not realled needed. OK deraadt@
* Use a macro for the initial length of the buffer instead of 127; OK deraadt@millert2017-03-141-3/+5

* Remove NULL-checks before free() and a few related dead assignments.mmcc2015-12-281-5/+3

* Add framework for resolving (pun intended) libc namespace issues, usingguenther2015-08-311-2/+2
| | | | | | | | | | | | 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@

* Make printf-like and scanf-like functions marked as such in llib-lc.lnmartynas2011-05-301-1/+2

* Fix the handle locking in stdio to use flockfile/funlockfilekurt2009-11-091-2/+2
| | | | | | | | | | | | | internally when and where required. Macros in <stdio.h> are updated to automatically call the underlying functions when the process is threaded to obtain the necessary locking. A private mutex is added to protect __sglue, the internal list of FILE handles, and another to protect the one-time initialization. Some routines in libc that use getc() change to use getc_unlocked() as they're either protected by their own lock or aren't thread-safe routines anyway. committing on behalf of and okay guenther@ now that we have install media space available.

| | | | | | | | | | | | | | | | extended attribute data structure (pimpl idiom). Idea taken from citrus. Much discussion with deraadt@, otto@, millert@... This is the least disruptive way to extend FILE, since its size can't really change without this being a flag day. So the size doesn't change. Actual additions to the structure will come in separate steps, since this change is nasty enough on its own. Tests by otto@ and others, careful reading of code by otto@ and millert@. This is definitely a major bump, and has been checked to not impact a full ports build.

ones in the glibc. Some man pages changes from FreeBSD (asprintf.c/vasprintf.c are not based on GNU or FreeBSD code).
