123d7c10b6 Found a font that has an empty SingleSubst mapping. While that's silly, it's not necessarily illegal. FontTools, however, would crash with an AssertionError upon compilation. Fixed. 2016-05-28 22:20:31 +09:00

cdda278bd4 Use ttLib.newTable when possible 
I learnt about it from [1] and seems like a nice thing to use.

4ac53ab8b8 add missing 'import sys' 
A couple of modules were relying on the fact that the 'sys' module was being implicitly imported by 'from py23 import *'.
The 'py23.__all__' does not include 'sys'. I think it's better to always import 'sys' explicitly when needed.

e3f3f4f976 [_m_a_x_p] rename 'allXMaxIsLsb' variable to 'allXMinIsLsb' for clarity's sake 
The previous 'allXMaxIsLsb' name was misleading.
The 'allXMinIsLsb' boolean variable cooresponds to the head table's Bit 1.
This is set whenever all glyphs have the bbox.xMin equal to the respective
left sidebearing (and therefore "left sidebearing point at x=0").

13e862da72 [meta] Remove comments about intentionally deviating from Apple's spec 
Today, Apple has kindly fixed a bug in the [specification of the
meta table](https://developer.apple.com/fonts/TrueType-Reference-Manual/RM06/Chap6meta.html).  The existing fonttools implementation matches the
revised specification.  Therefore, the comments about fonttools
intentionally deviating from Apple's spec can be removed.

4b94fd55cb Simplify overflow handling code 
The code that is being removed is untested and does not seem to make
fixing an overflow any easier.  The fixer code just needs to know
which subtable caused the overflow and does not care about the item
within.  As such, no point in trying to find a "right" item.

In fact, leaving item as is, is more useful in debugging overflows
as it reflects which item's offset actually overflowed.

d82a31dd57 return NotImplemented from __ne__ if __eq__ returns NotImplemented 
otherwise `not NotImplemented` (always False) is returned from __ne__ when `type(self) != type(other)`, leading to illogic results like:

>>> from fontTools.ttLib.tables.DefaultTable import DefaultTable
>>> t = DefaultTable('test')
>>> t == 0
False
>>> t != 0
False

The latter of course should return True.

bf28ca10d7 [EBLC] Decompile and release copies of data early 
Apparently string slices are not as smart as I was hoping for.
Slicing a looong (say, 1MB) string and holding onto it is not a
good idea if done thousands of times.  So, do fewer slicings and
decompile subtables immediately instead of holding onto data.

This makes me want to rethink the kind of data structures we use
for lazy processing.
