Behdad Esfahbod ad3653751b Typo 2010-04-23 19:43:40 -04:00

Behdad Esfahbod 187454c595 Add different casts from pointer and ref to avoid bugs 2010-04-23 17:44:28 -04:00
Behdad Esfahbod efb324a46f Remove GET_FOR_DATA macros 
The major-version check is now handled by sanitize.  If major
doesn't match, we reject and fall back to the Null object.

Behdad Esfahbod 254933c397 When sanitizing, delay making writable 
Before, as soon as we needed to make an edit, we tried to make the blob
writable inplace.  That grows code unnecessarily though.  We can simply
fail, make writable, then start again.  That's indeed what the fallback
was doing anyway.

Behdad Esfahbod a065f471b3 Cleanup Extension lookups 
Two things:

1. Allow nested Extension lookups.  The offset is always positive, so
it can't loop circularly.

2. Move the check for all Extension subtables having the same lookup
type to the correct place.  Before it wasn't really working.

Behdad Esfahbod 4b8487d83e Fix the mystery bug! 
A couple bugs joined forces to exhibit the mystery behavior of
crashes / infinite loops on OS X / wrong kerning / invalid memory
access.  Pooh!

The bugs were involved:

  - Wrong pointer math with ValueRecord in PairPosFormat1

  - Fallout from avoiding flex arrays, code not correctly updated
    to remove sizeof() usage.

We strictly never use sizeof() directly now.  And the PairPos code
is cleaned up.  Should fix them all.  Bugs are:

  Bug 605655 - Pango 1.26.2 introduces kerning bug
  Bug 611229 - Pango reads from uninitialized memory
  Bug 593240 - (pangoosx) Crash / infinite loop with Mac OS X

We were also doing wrong math converting Device adjustments to
hb_position_t.  Fallout from FreeType days.  Should shift 16, not
6.  Fixed that too.

There's still another bug: we don't sanitize Device records
referenced from value records.  Fixing that also.

Behdad Esfahbod 807b8aa486 Another C++ strictness fix 
Pango Bug 602408 - Invalid C++ code breaks compile with Sun C++ Compiler
(Error: A union member cannot have a user-defined assignment operator)

According to the bug:

C++ Programming Language by Bjarne Stroustrup: Chapter 10.4.12 forbids
explicitly using of union members with constructors, destructors or assignment
operations.

So we use a set() method instead of the assignment operator.  Ugly, but hey,
that's life.

If someone wants to inhibit duplicating, they can lock the blob
and throw away the key.

        Remove ClassDef->Defined field.  This is the comment accompanying it:

          The `Defined' field is not defined in the OpenType specification
          but apparently needed for processing fonts like trado.ttf: This
          font refers to a class which contains not a single element.  We
          map such classes to class 0.

        The comment is correct that trado.ttf (MS Traditional Arabic) uses
        such classes.  However, in my testing I couldn't identify any
        problems with the font if the special handling is removed.  I also
        processed as many fonts as I could get my hand on and trado.ttf was
        the only not-totally-broken font hitting the special-case code.
        DejaVu fonts hit it too, but I'm sure they do not require the
        special-handling code.  Most probably, that code introduces bugs
        in them.

        The special-casing was consuming lots of memory.  EIGHT MEGABYTES
        for loading DejaVu Sans!  While this could be complete fixed, I
        decided to remove the special-handling code altogether.  I don't
        think it will make any real difference, and if it does, we'll fix
        fonts.  Such hacks will not be in harfbuzz-ng anyway.

        Bug originally reported by nsf.

        Bug 485559 – Boston Summit HarfBuzz optimizations

        * pango/opentype/*: HarfBuzz hacking to:

          - Rename last remaining FT_Err stuff to HB_Err.

          - Fix a couple invalid table paths to be permissive so
            fonts work better.  Particularly GDEF table for Nafees
            Nastaliq is loaded and works great now.

          - Optimize harfbuzz buffer to not copy/swap for simple
          one-to-one and "copy" GSUB operations.

        * pango/pango-ot*: Update to FT_Err to HB_Err renaming.
