Tim-Philipp Müller	e8a9f7acdf	printf: fix handling of old printf extension specifiers for ABI compatibility ... Fixes abort when the old specifiers are used. Fix up the conversion specifier, it would get overwritten with 'c' below to the extension format char, which then later is unhandled, leading to the abort. Also fix up and enable unit test for this. https://bugzilla.gnome.org/process_bug.cgi	2013-04-18 00:46:58 +01:00
Tim-Philipp Müller	109be629b7	printf: disable some unused printf variants	2013-04-14 11:33:41 +01:00
Tim-Philipp Müller	91c42b9380	printf: use sprintf() to work around glibc complaining about %n in a writable format string ... Don't use snprintf(), but use sprintf instead and do our own length calculations, because glibc may complain about us passing %n in a format string if the string is in writable memory, and here the format string is always in writable memory since we construct it on the fly. This happens if glibc has been compiled with _FORTIFY_SOURCE=2, which seems to be the case on some distros/systems). On the upside, we now use the sprintf code path on all systems which should be better from a maintenance point of view. https://bugzilla.gnome.org/show_bug.cgi?id=697970	2013-04-14 11:23:10 +01:00
Tim-Philipp Müller	5299a0cd65	printf: deal with some of the HAVE_FOO used in the printf code ... Probably needs some more work for MSVC.	2013-04-12 23:05:59 +01:00
Tim-Philipp Müller	3c1d9c6d41	printf: fix alloca use for windows with mingw32 ... Don't use just GLIB_HAVE_ALLOCA_H to check if alloca is available, that's just for the header. GLib may define alloca for us otherwise too irrespective of GLIB_HAVE_ALLOCA_H. Fixes compiler warning with mingw32: gst/printf/vasnprintf.c:73:0: warning: "alloca" redefined	2013-04-12 23:05:58 +01:00
Tim-Philipp Müller	ff292d530c	printf: enable and fix compiler warnings ... But suppress -Wformat-nonliteral warnings since sprintf is used with a runtime-generated format string in our vasnprintf implementation.	2013-04-12 23:05:58 +01:00
Tim-Philipp Müller	97b3948a9f	printf: fix up dodgy use of #if HAVE_FOO and #if !HAVE_FOO ... Should use #ifdef and #ifndef.	2013-04-12 23:05:58 +01:00
Tim-Philipp Müller	79d6b91e27	printf: mark internal functions as internal	2013-04-12 23:05:57 +01:00
Tim-Philipp Müller	3778c1878c	printf: skip pointer extension signifier chars after %p ... So they don't get printed after the serialised pointer string.	2013-04-12 23:05:57 +01:00
Tim-Philipp Müller	6d8a6470d5	printf: don't leak serialised pointer extension strings	2013-04-12 23:05:57 +01:00
Tim-Philipp Müller	9a9b449c5f	printf: handle old GST_PTR_FORMAT %P and GST_SEGMENT_FORMAT %Q defines too ... For binary backwards compatibility.	2013-04-12 23:05:57 +01:00
Tim-Philipp Müller	5803da553c	printf: make printf parser recognise our pointer extension format ... and call the hook to get a string for the pointer instead. https://bugzilla.gnome.org/show_bug.cgi?id=613081	2013-04-12 23:05:57 +01:00
Tim-Philipp Müller	fe7f7135e0	printf: add infrastructure for pointer extensions hook ... Does not do anything yet. On a sidenote, we can't just use %p\001 or so to signal the extension because g-i complains about an invalid ascii character then, so have to resort to something more elaborate, such as %p\aA etc. https://bugzilla.gnome.org/show_bug.cgi?id=613081	2013-04-12 23:05:57 +01:00
Tim-Philipp Müller	8fc876f09f	printf: add our own printf implementation for debug logging ... We will add support for our own printf modifiers, so we can get nice debug log output on all operating systems irrespective of the specific libc version used. https://bugzilla.gnome.org/show_bug.cgi?id=613081	2013-04-12 23:05:56 +01:00
