2012-09-06	use restrict everywhere it's required by c99 and/or posix 2008	Rich Felker	-1/+1
	to deal with the fact that the public headers may be used with pre-c99 compilers, __restrict is used in place of restrict, and defined appropriately for any supported compiler. we also avoid the form [restrict] since older versions of gcc rejected it due to a bug in the original c99 standard, and instead use the form *restrict.
2012-06-07	fix scanf bug reading literals after width-limited field	Rich Felker	-0/+1
	the field width limit was not being cleared before reading the literal, causing spurious failures in scanf in cases like "%2d:" scanning "00:".
2012-04-19	fix really bad breakage in strtol, etc.: failure to accept leading spaces	Rich Felker	-1/+1

2012-04-17	fix over-read in %ls with non-wide scanf	Rich Felker	-0/+1

2012-04-17	fix some bugs in scanf %[ handling detected while writing the wide version	Rich Felker	-4/+4

2012-04-17	avoid null pointer dereference on %*p fields in scanf	Rich Felker	-1/+1

2012-04-16	new scanf implementation and corresponding integer parser/converter	Rich Felker	-16/+322
	advantages over the old code: - correct results for floating point (old code was bogus) - wide/regular scanf separated so scanf does not pull in wide code - well-defined behavior on integers that overflow dest type - support for %[a-b] ranges with %[ (impl-defined by widely used) - no intermediate conversion of fmt string to wide string - cleaner, easier to share code with strto* functions - better standards conformance for corner cases the old code remains in the source tree, as the wide versions of the scanf-family functions are still using it. it will be removed when no longer needed.
2011-03-28	major stdio overhaul, using readv/writev, plus other changes	Rich Felker	-10/+3
	the biggest change in this commit is that stdio now uses readv to fill the caller's buffer and the FILE buffer with a single syscall, and likewise writev to flush the FILE buffer and write out the caller's buffer in a single syscall. making this change required fundamental architectural changes to stdio, so i also made a number of other improvements in the process: - the implementation no longer assumes that further io will fail following errors, and no longer blocks io when the error flag is set (though the latter could easily be changed back if desired) - unbuffered mode is no longer implemented as a one-byte buffer. as a consequence, scanf unreading has to use ungetc, to the unget buffer has been enlarged to hold at least 2 wide characters. - the FILE structure has been rearranged to maintain the locations of the fields that might be used in glibc getc/putc type macros, while shrinking the structure to save some space. - error cases for fflush, fseek, etc. should be more correct. - library-internal macros are used for getc_unlocked and putc_unlocked now, eliminating some ugly code duplication. __uflow and __overflow are no longer used anywhere but these macros. switch to read or write mode is also separated so the code can be better shared, e.g. with ungetc. - lots of other small things.
