[set/map/vector] Make constructable, but not copy or assignable
...
Disable copy/assign on them, as they shouldn't.
Make constructor / destructor call init_shallow/fini_shallow,
and make those idempotent. So, these three can be constructed
on stack now and no init/fini call is needed. As such,
hb_auto_t<> is not needed anymore. I'll remove that separately.

Remove ASSERT_POD
...
Newer compilers / language allows structs with constructor in union.
So, this was not actually testing anything. Indeed, the recent
change in DISALLOW_COPY *is* making some of our types non-POD.
That broke some bots.
Just remove this since it wasn't doing much, and I'd rather have
DISALLOW_COPY.

Make Array types uncopyable-unassignable
...
Finally! Catches hard-to-find errors like this:
- const SortedArrayOf<SVGDocumentIndexEntry> docs = this+svgDocEntries;
+ const SortedArrayOf<SVGDocumentIndexEntry> &docs = this+svgDocEntries;
We implement this for our array types. This, in turn, trickles down
into all types that embed the arrays. So, as long as we define all
open-ended structs in terms of Array types (all can be done using
UnsizedArrayOf), this achieves the goal of making uncopyable all
structs that are variable-sized. Yay!

When hb_set_t::page_for_insert needs to insert at the end of the page_map
it ends up evaluating '&page_map[i + 1]' which has hb_vector return an
lvalue of a Crap so that nothing can be moved to its address. This turns
into issues with ThreadSanitizer on Crap when two threads modify different
hb_set_t instances. This can be avoided by using '&page_map[i] + 1'
instead.

And on -arabic.cc, step can goes one number higher than step_t enum in the

Map Quechua languages to closest ones with tags
...
OpenType only officially maps four ISO 639 codes to Quechua languages,
but prior versions of HarfBuzz also mapped qu to 'QUZ '. Because qu is a
macrolanguage, the mapping now applies to all individual Quechua
languages. OpenType calls 'QUZ ' "Quechua", but it really corresponds to
Cusco Quechua, so the individual Quechua languages should not all
necessarily be mapped to it.
2018-10-11 13:54:28 -04:00
7c7cb2a989
Match extlang subtags
...
If the second subtag of a BCP 47 tag is three letters long, it denotes
an extended language. The tag converter ignores the language subtag and
uses the extended language instead.
There are some grandfathered exceptions, which are handled earlier.
2018-10-11 13:54:28 -04:00
2f1f961cc0
Autogenerate the BCP 47 to OpenType mappings
...
The new script, gen-tag-table.py, generates `ot_languages` automatically
from the [OpenType language system tag registry][ot] and the [IANA
Language Subtag Registry][bcp47] with some manual modifications. If an
OpenType tag maps to a BCP 47 macrolanguage, all the macrolanguage's
individual languages are mapped to the same OpenType tag, except for
individual languages with their own OpenType mappings. Deprecated
BCP 47 tags are canonicalized.
[ot]: https://docs.microsoft.com/en-us/typography/opentype/spec/languagetags
[bcp47]: https://www.iana.org/assignments/language-subtag-registry/language-subtag-registry
Some OpenType tags correspond to multiple ISO 639 codes. The mapping
from ISO 639 codes lists OpenType tags in priority order, such that more
specific or more likely tags appear first.
Some OpenType tags have no corresponding ISO 639 code in the registry so
their mappings use BCP 47 subtags besides the language. For example, any
BCP 47 tag with a fonipa variant subtag is mapped to 'IPPH', and 'IPPH'
is mapped back to und-fonipa.
Other OpenType tags have no corresponding ISO 639 code because it is not
clear what they are for. HarfBuzz just ignores these tags.
One such ignored tag is 'ZHP ' (Chinese Phonetic). It probably means
zh-Latn. However, it is used in Microsoft JhengHei and Microsoft YaHei
with the script tag 'hani', implying that it is not a romanization
scheme after all. It would be simple enough to add this mapping to
gen-tag-table.py once a definitive mapping is determined.
The manual modifications are mainly either obvious mappings that the
OpenType registry omits or mappings for compatibility with previous
versions of HarfBuzz. Some of the old mappings were discarded, though,
for homophonous language names. For example, OpenType maps 'KUI ' to
kxu; previous versions of HarfBuzz also mapped it to kvd, because kvd
and kxu both happen to be called "Kui".
gen-tag-table.py also generates a function to convert multi-subtag tags
like el-polyton and zh-HK to OpenType tags, replacing `ot_languages_zh`
and the hard-coded list of special cases in `hb_ot_tags_from_language`.
It also generates a function to convert OpenType tags to BCP 47,
replacing the hard-coded list of special cases in
`hb_ot_tag_to_language`.

Refactor the selection of script and language tags
...
The old hb-ot-tag.cc functions, `hb_ot_tags_from_script` and
`hb_ot_tag_from_language`, are now wrappers around a new function:
`hb_ot_tags`. It converts a script and a language to arrays of script
tags and language tags. This will make it easier to add new script tags
to scripts, like 'dev3'. It also allows for language fallback chains;
nothing produces more than one language yet though.
Where the old functions return the default tags 'DFLT' and 'dflt',
`hb_ot_tags` returns an empty array. The caller is responsible for
using the default tag in that case.
The new function also adds a new private use subtag syntax for script
overrides: "x-hbscabcd" requests a script tag of 'abcd'.
The old hb-ot-layout.cc functions,`hb_ot_layout_table_choose_script` and
`hb_ot_layout_script_find_language` are now wrappers around the new
functions `hb_ot_layout_table_select_script` and
`hb_ot_layout_script_select_language`. They are essentially the same as
the old ones plus a tag count parameter.
Closes #495 .

I don't see the GPOS table in the font do the same. ¯\_(ツ)_/¯

Tested that Format0 works with Kannada MN font:

[kn_ka=0+1000|kn_matra_uu=0@-30,0+1345]

[kn_ka=0+1030|kn_matra_uu=0+1375]
Note that GPOS does the same with 'dist' feature, and applies the whole difference to the
same glyph:
$ make -j5 lib -s && ./hb-shape Kannada\ MN.ttc -u 0C95,0CC2
[kn_ka=0+970|kn_matra_uu=0+1375]
$ make -j5 lib -s && ./hb-shape Kannada\ MN.ttc -u 0C95,0CC2 --features=-dist
[kn_ka=0+1030|kn_matra_uu=0+1375]

[ot-font] Don't pre-load cmap table
...
Now that we have get_h_advances() and get_nominal_glyphs() implemented, the
overhead of doing a proper atomic load would be once per run, NOT once per
glyph. So, no need to pre-load the tables to avoid that overhead.
As such, hb_ot_font_set_funcs() has become really cheap. Can *finally* make
it be default font functions on all newly created fonts!

[ot/ft] Implement get_nominal_glyphs() callback
...
Some more measurable speedup. The recent commits' speedups are as follows:
Testing with Roboto, ****when disabling kern and liga****:
Before:
FT --features=-kern,-liga
user↦ 0m0.521s
OT --features=-liga,-kern
user↦ 0m0.568s
After:
FT --features=-liga,-kern
user↦ 0m0.428s
OT --features=-liga,-kern
user↦ 0m0.470s
So, 17% speedup.
Note that FT callbacks are faster than OT these days since we added an advance
cache to FT. I don't think the difference is enough to justify adding a cache
to OT.
When not disabling kern, the thing is three times slower, so the speedups
are three times less impressive... Still, 5% not bad for a codebase that I
otherwise thought is optimized out.
Note that, because of this and other optimiztions in our main shaper,
disabling kern and liga, the OT shaper is now *faster* than the fallback
shaper. So, that's my recommendation to clients that need the absolute
fastest...

Instead of passing a CFLAG/CXXFLAG to define HB_EXTERN, define it
directly in src/hb.hh as __declspec(dllexport) extern when we are
building HarfBuzz as DLLs on Visual Studio. Define HB_INTERNAL
as nothing without defining HB_NO_VISIBILITY when building HarfBuzz as
DLLs to avoid linker errors on Visual Studio builds.
Also "install" harfbuzz-subset.dll into $(PREFIX)\bin as the
hb-subset utility will depend on that DLL at runtime, when HarfBuzz is
built as DLLs. Since it consists of private APIs that are subject to
change, we do not install its headers nor .lib file.

"The values in the right class table are stored pre-multiplied by the

class table are stored pre-multiplied by the number of bytes in one
row. This eliminates needing to multiply the row and column values
together to determine the location of the kerning value. The array can
be indexed by doing the right- and left-hand class mappings, adding the
class values to the address of the array, and fetching the kerning
value to which the new address points."
