*	printf-hook-builtin: Fix invalid memory access	Tobias Brunner	2015-08-04	1	-1/+2
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	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: ==19215== Invalid read of size 1 ==19215== at 0x52D36C6: builtin_vsnprintf (printf_hook_builtin.c:853) ==19215== by 0x52D40A8: builtin_snprintf (printf_hook_builtin.c:1084) ==19215== by 0x52CE464: dntoa (identification.c:337) ==19215== by 0x52CE464: identification_printf_hook (identification.c:837) ==19215== by 0x52D3DAA: builtin_vsnprintf (printf_hook_builtin.c:1010) ==19215== by 0x57040EB: vlog (bus.c:388) ==19215== by 0x570427D: log_ (bus.c:430) ==19215== by 0xA8445D3: load_x509_ca (stroke_cred.c:416) ==19215== by 0xA8445D3: load_certdir (stroke_cred.c:537) ==19215== by 0xA846A95: load_certs (stroke_cred.c:1353) ==19215== by 0xA846A95: stroke_cred_create (stroke_cred.c:1475) ==19215== by 0xA84073E: stroke_socket_create (stroke_socket.c:782) ==19215== by 0xA83F27C: register_stroke (stroke_plugin.c:53) ==19215== by 0x52C3125: load_feature (plugin_loader.c:716) ==19215== by 0x52C3125: load_provided (plugin_loader.c:778) ==19215== by 0x52C3A20: load_features (plugin_loader.c:799) ==19215== by 0x52C3A20: load_plugins (plugin_loader.c:1159) ==19215== Address 0x50cdb42 is 0 bytes after a block of size 2 alloc'd ==19215== at 0x4C919FE: malloc (vg_replace_malloc.c:296) ==19215== by 0x52CD198: chunk_printable (chunk.c:759) ==19215== by 0x52CE442: dntoa (identification.c:334) ==19215== by 0x52CE442: identification_printf_hook (identification.c:837) ==19215== by 0x52D3DAA: builtin_vsnprintf (printf_hook_builtin.c:1010) ==19215== by 0x57040EB: vlog (bus.c:388) ==19215== by 0x570427D: log_ (bus.c:430) ==19215== by 0xA8445D3: load_x509_ca (stroke_cred.c:416) ==19215== by 0xA8445D3: load_certdir (stroke_cred.c:537) ==19215== by 0xA846A95: load_certs (stroke_cred.c:1353) ==19215== by 0xA846A95: stroke_cred_create (stroke_cred.c:1475) ==19215== by 0xA84073E: stroke_socket_create (stroke_socket.c:782) ==19215== by 0xA83F27C: register_stroke (stroke_plugin.c:53) ==19215== by 0x52C3125: load_feature (plugin_loader.c:716) ==19215== by 0x52C3125: load_provided (plugin_loader.c:778) ==19215== by 0x52C3A20: load_features (plugin_loader.c:799) ==19215== by 0x52C3A20: load_plugins (plugin_loader.c:1159)
*	printf-hook-builtin: Support Windows console colors using TTY escape codes	Martin Willi	2014-06-04	1	-0/+124
\|
*	printf-hook-builtin: Correctly calculate written bytes in print_in_hook()	Martin Willi	2014-01-15	1	-3/+7
\| \| \| \| \| \| \| \| \| \|	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	Martin Willi	2013-11-20	1	-6/+0
\| \| \| \|	We use %P as custom printf specifier for proposals.
*	printf-hook-builtin: Don't rely on isinf() return value signedness	Martin Willi	2013-10-24	1	-8/+9
\| \| \| \| \|	Many systems don't return a negative value for negative infinities; so do a separate check.
*	printf-hook-builtin: Print NaN/Infinity floating point values as such	Martin Willi	2013-10-11	1	-2/+22

*	printf-hook-builtin: Correctly round up floating point values	Martin Willi	2013-10-11	1	-1/+15

*	printf-hook-builtin: Add some preliminary floating point support	Martin Willi	2013-10-11	1	-2/+194
\| \| \| \| \|	This minimalistic implementation has no aspiration for completeness or accuracy, and just provides what we need.
*	printf-hook-builtin: Support GNU %m specifier	Martin Willi	2013-10-11	1	-0/+8
\|
*	printf-hook-builtin: Add a new "builtin" backend using its own printf() routines	Martin Willi	2013-10-11	1	-0/+933
	Overloads printf C library functions by a self-contained implementation, based on klibc. Does not yet feature all the required default formatters, including those for floating point values.
