2014-01-08	add __isoc99_vfscanf weak alias to vfscanf	Szabolcs Nagy	-0/+2
	this glibc abi compatibility function was missed when the scanf aliases were added.
2013-12-12	include cleanups: remove unused headers and add feature test macros	Szabolcs Nagy	-4/+1

2013-08-31	avoid crash in scanf when invalid %m format is encountered	Rich Felker	-0/+2
	invalid format strings invoke undefined behavior, so this is not a conformance issue, but it's nicer for scanf to report the error safely instead of calling free on a potentially-uninitialized pointer or a pointer to memory belonging to the caller.
2013-07-20	fix uninitialized/stale use of alloc (%m modifier) flag in scanf	Rich Felker	-0/+2
	for conversion specifiers, alloc is always set when the specifier is parsed. however, if scanf stops due to mismatching literal text, either an uninitialized (if no conversions have been performed yet) or stale (from the previous conversion) of the flag will be used, possibly causing an invalid pointer to be passed to free when the function returns.
2013-06-22	fix scanf %c conversion wrongly storing a terminating null byte	Rich Felker	-2/+4
	this seems to have been a regression from the refactoring which added the 'm' modifier.
2013-06-05	implement the 'm' (malloc) modifier for scanf	Rich Felker	-22/+48
	this commit only covers the byte-based scanf-family functions. the wide functions still lack support for the 'm' modifier.
2013-06-04	simplify some logic in scanf and remove redundant invalid-format check	Rich Felker	-18/+8

2013-06-04	refactor scanf core to use common code path for all string formats	Rich Felker	-85/+52
	the concept here is that %s and %c are essentially special-cases of %[, with some minimal additional special-casing. aside from simplifying the code and reducing the number of complex code-paths that would need changing to make optimizations later, the main purpose of this change is to simplify addition of the 'm' modifier which causes scanf to allocate storage for the string being read.
2012-11-08	clean up stdio_impl.h	Rich Felker	-1/+1
	this header evolved to facilitate the extremely lazy practice of omitting explicit includes of the necessary headers in individual stdio source files; not only was this sloppy, but it also increased build time. now, stdio_impl.h is only including the headers it needs for its own use; any further headers needed by source files are included directly where needed.
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.
2011-02-12	initial check-in, version 0.5.0v0.5.0	Rich Felker	-0/+43
