printf-hook-builtin: Fix invalid memory access

2015-08-04T12:19:26+00:00

When precision is given for a string, we must not run unbounded
strlen() as it will read beyond the given length. It might even cause
a crash if the given pointer is near end of heap or mapping.

Fixes numerous valgrind errors such as:

printf-hook-builtin: Support Windows console colors using TTY escape codes

printf-hook-glibc: printf.h on FreeBSD 10 does not include stdargs.h

printf-hook-builtin: Correctly calculate written bytes in print_in_hook()

2014-01-15T17:28:43+00:00

The hook data counts remaining buffer bytes, not used ones. Counting them
correctly fixes a crash for long hexdumps.

Further, print_in_hook() must return the number of bytes that would have been
written, not the actually written bytes. This is important, as we allocate a
dynamic buffer in bus that relies on the exact byte count. Fixes long hexdumps
that got truncated.

printf-hook-builtin: Don't use %P to print uppercase hex pointers

2013-11-20T15:57:28+00:00

We use %P as custom printf specifier for proposals.

printf-hook-builtin: Don't rely on isinf() return value signedness

2013-10-24T13:37:20+00:00

Many systems don't return a negative value for negative infinities; so do
a separate check.

vstr: Forward actual field width

2013-10-11T13:12:16+00:00

fmt_field_width is a flag that indicates if a field width
is defined in obj_field_width.
