Behdad Esfahbod 05fabbd03e [unsafe-to-break] Towards verifying unsafe-to-break in --verify
We break and shape fragments and reconstruct shape result from them.
Remains to compare to original buffer.  Going to add some buffer
comparison API and use here, instead of open-coding.

Behdad Esfahbod d2052278f2 [util] Add --verify to hb-shape / hb-view that verifies shape results
Right now it checks for monotone cluster values.  Other checks to be added.

Behdad Esfahbod 40bd7e9a1c [unsafe-to-break] Add UNSAFE_TO_BREAK flag
Not all shapers code is updated to set this properly.
GSUB and Arabic shaper are updated.
GPOS and other shapers are NOT.

Behdad Esfahbod e60350551a [hb-shape] Improve shaping-debug output
Before, that was printed using --debug (and in both hb-shape and hb-view).
Changed it, now hb-shape has a new command-line argument called --show-messages.
When invoked, it also respects other output formatting options.  The messages
are better formatted and printed to te same place that hb-shape output is
directed to.  Previously they were written to stderr.

build systems, such as NMake for Visual Studio.

Chun-wei Fan a49e7b7e40 MSVC builds: Add fallback implementation for pre-2013 MSVC
Pre-2013 MSVC does not have scalbn() and scalbnf(), which are used in the
utility programs.  Add  fallback implementations for these, which can be
used when necessary.
2015-11-16 23:04:36 +08:00
Chun-wei Fan 998e8dda93 util: Fix build on Visual Studio
Use the fallback implementation for lround() only on pre-2013 Visual
Studio, and ensure we are clear about the types of the parameters for
lround() and scalbnf(), since Visual Studio can be quite picky on
ambiguous parameter types.  Also, use g_ascii_strcasecmp() rather than
strcasecmp() as we are already using GLib for this code and we are
assured that g_ascii_strcasemp() is available.

For scalbnf() on pre-2013 Visaul Studio, a fallback implementation is
needed, but use another forced-included header for those compilers, which
will be added later.

Also use (char)27 on Visual Studio builds as '\e' is not a recognized
escape sequence, which will do the same thing.

Behdad Esfahbod 642135f3b2 [util] In --debug mode, duplicate font data
This has the effect that the font data will end up in a memory
section malloc()ed exactly to its size.  This gives us better
valgrind detection of out-of-bounds access.

Previously, the font data was placed in a mmap()ed section or
GString-allocated area, which didn't have proper protections
at the end when running under valgrind.

Behdad Esfahbod c462b32dcb Disable automatic segment properties guessing
Before, if one called hb_shape() without setting script, language, and
direction on the buffer, hb_shape() was calling
hb_buffer_guess_segment_properties() on the user's behalf to guess
these.

This is very dangerous, since any serious user of HarfBuzz must set
these properly (specially important is direction).  So now, we don't
guess properties by default.  People not setting direction will get
an abort() now.  If the old behavior is desired (fragile, good for
simple testing only), users can call
hb_buffer_guess_segment_properties() on the buffer just before calling
hb_shape().
