2012-04-18fix header typoRich Felker1-1/+1
2012-04-18legacy junk compatibility grab-bagRich Felker6-7/+36
- add the rest of the junk traditionally in sys/param.h - add prototypes for some nonstandard functions - add _GNU_SOURCE to their source files so the compiler can check proto
2012-04-18fix incorrect macro name for MATH_ERREXCEPT in math.hRich Felker1-1/+1
2012-04-18release notes for 0.8.8Rich Felker1-0/+34
2012-04-18fix typo in exponent reading code or floatsRich Felker1-1/+1
this was basically harmless, but could have resulted in misreading inputs with more than a few gigabytes worth of digits..
2012-04-17fix wide scanf's handling of input failure on %c, and simplify %[Rich Felker1-5/+6
2012-04-17fix failure to distinguish input/match failure in wide %[ scanfRich Felker2-2/+4
this also includes a related fix for vswscanf's read function, which was returning a spurious (uninitialized) character for empty strings.
2012-04-17fix over-read in %ls with non-wide scanfRich Felker1-0/+1
2012-04-17fix broken %s and %[ with no width specifier in wide scanfRich Felker1-3/+7
2012-04-17fix failure to read infinity in scanfRich Felker1-3/+4
this code worked in strtod, but not in scanf. more evidence that i should design a better interface for discarding multiple tail characters than just calling unget repeatedly...
2012-04-17fix failure of int parser to unget an initial mismatching characterRich Felker1-0/+1
2012-04-17make wide scanf %[ respect widthRich Felker1-2/+3
2012-04-17fix wide scanf to respect field width for stringsRich Felker1-4/+7
2012-04-17fix some bugs in scanf %[ handling detected while writing the wide versionRich Felker1-4/+4
2012-04-17introduce new wide scanf code and remove the last remnants of old scanfRich Felker4-524/+312
at this point, strto* and all scanf family functions are using the new unified integer and floating point parser/converter code. the wide scanf is largely a wrapper for ordinary byte-based scanf; since numbers can only contain ascii characters, only strings need to be handled specially.
2012-04-17avoid depending on POSIX symbol in code used from plain C functionsRich Felker1-1/+3
2012-04-17avoid null pointer dereference on %*p fields in scanfRich Felker1-1/+1
2012-04-17also ensure that write buffer is bounded when __stdio_write returnsRich Felker1-0/+1
assuming other code is correct, this should be a no-op, but better to be safe...
2012-04-17fix buffer overflow in vfprintf on long writes to unbuffered filesRich Felker1-1/+2
vfprintf temporarily swaps in a local buffer (for the duration of the operation) when the target stream is unbuffered; this both simplifies the implementation of functions like dprintf (they don't need their own buffers) and eliminates the pathologically bad performance of writing the formatted output with one or more write syscalls per formatting field. in cases like dprintf where we are dealing with a virgin FILE structure, everything worked correctly. however for long-lived files (like stderr), it's possible that the buffer bounds were already set for the internal zero-size buffer. on the next write, __stdio_write would pick up and use the new buffer provided by vfprintf, but the bound (wend) field was still pointing at the internal zero-size buffer's end. this in turn allowed unbounded writes to the temporary buffer.
2012-04-16fix %lf, etc. with printfRich Felker1-0/+2
the l prefix is redundant/no-op with printf, since default promotions always promote floats to double; however, it is valid, and printf was wrongly rejecting it.
2012-04-16better description for errno==0Rich Felker1-1/+1
