* builds/unix/configure.raw (version_info): Set to 12:1:6.
2010-10-03 Werner Lemberg <wl@gnu.org>
Avoid `configure' issues with symbolic links.
Based on a patch from Alexander Stohr <Alexander.Stohr@gmx.de>.
* configure: Compare directories using `ls -id'.
Check existence of `reference' subdirectory before creating it.
2010-10-02 Werner Lemberg <wl@gnu.org>
Fix Savannah bug #31088 (sort of).
* src/sfnt/ttload.c (tt_face_load_maxp): Always allocate at least 64
function entries.
2010-10-02 Werner Lemberg <wl@gnu.org>
[smooth] Fix splitting of cubics for negative values.
Reported by Róbert Márki <gsmiko@gmail.com>; see
http://lists.gnu.org/archive/html/freetype/2010-09/msg00019.html.
* src/smooth/ftgrays.c (gray_render_cubic): Fix thinko.

Fix Savannah bug #31040.
* src/truetype/ttinterp.c (free_buffer_in_size): Remove.
(TT_RunIns): Updated.
2010-09-20 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
[sfnt] Make error message filling NULL names less verbose.
* src/sfnt/ttpost.c (load_format_20): Showing 1 summary message
when we fill `post' names by NULL, instead of per-entry message.
2010-09-20 Graham Asher <graham.asher@btinternet.com>
David Bevan <david.bevan@pb.com>
[smooth] Fix and improve spline flattening.
This fixes the flattening of cubic, S-shaped curves and speeds up
the handling of both the conic and cubic arcs.
See the discussions on the freetype-devel mailing list in late
August and September 2010 for details.
* src/smooth/ftgrays.c (FT_MAX_CURVE_DEVIATION): New macro.
(TWorker): Remove `conic_level' and `cubic_level' elements.
(gray_render_conic): Simplify algorithm.
(gray_render_cubic): New algorithm; details are given in the code
comments.
(gray_convert_glyph): Remove heuristics.
2010-09-19 Werner Lemberg <wl@gnu.org>
Minor fixes.
* src/cff/cffload.c (cff_charset_compute_cids): `charset->sids[i]'
is `FT_UShort'.
(cff_index_access_element): Don't use additions in comparison.
* src/sfnt/ttpost.c (load_format_20): Make `post_limit' of type
`FT_Long'.
Don't use additions in comparison.
Improve tracing messages.
(load_format_25, load_post_names): Make `post_limit' of type
`FT_Long'.
2010-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
[cff] Truncate the element length at the end of the stream.
See Savannah bug #30975.
* src/cff/cffload.c (cff_index_access_element): `off2', the offset
to the next element is truncated at the end of the stream to prevent
invalid I/O. As `off1', the offset to the requested element has
been checked by FT_STREAM_SEEK(), `off2' should be checked
similarly.
2010-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
[cff] Ignore CID > 0xFFFFU.
See Savannah bug #30975.
* src/cff/cffload.c (cff_charset_compute_cids): Ignore CID if
greater than 0xFFFFU. CFF font spec does not mention maximum CID in
the font, but PostScript and PDF spec define that maximum CID is
0xFFFFU.
2010-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
[cff] Make trace message in cff_charset_load() verbose.
See Savannah bug #30975.
* src/cff/cffload.c (cff_charset_load): Report the original `nleft'
and truncated `nleft'.
2010-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
[cff] Correct `max_cid' from CID array length to max CID.
See Savannah bug #30975.
* src/cff/cffload.c (cff_charset_compute_cids): Don't increment
max_cid after detecting max CID. The array CFF_Charset->cids is
allocated by max_cid + 1.
(cff_charset_cid_to_gindex): Permit CID is less than or equal to
CFF_Charset->max_cid.
* src/cff/cffobjs.c (cff_face_init): FT_Face->num_glyphs is
calculated as CFF_Charset->max_cid + 1.
2010-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
[truetype] Sanitize the broken offsets in `loca'.
See Savannah bug #31040.
* src/truetype/ttpload.c (tt_face_get_location): If `pos1', the
offset to the requested entry in `glyf' exceeds the end of the
table, return offset=0, length=0. If `pos2', the offset to the next
entry in `glyf' exceeds the end of the table, truncate the entry
length at the end of `glyf' table.
2010-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
[sfnt] Prevent overrunning in `post' table parser.
See Savannah bug #31040.
* src/sfnt/ttpost.c (load_post_names): Get the length of `post'
table and pass the limit of `post' table to load_format_20() and
load_format_25().
(load_format_20): Stop the parsing when we reached at the limit of
`post' table. If more glyph names are required, they are filled by
NULL names.
2010-09-17 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
[truetype] Don't duplicate size->twilight structure to be freed.
See Savannah bug #31040 for detail.
* src/truetype/ttinterp.c (free_buffer_in_size): Don't duplicate
FT_GlyphZoneRec size->twilight to be freed. If duplicated,
FT_FREE() erases the duplicated pointers only and leave original
pointers. They can cause the double-free crash when the burst
errors occur in TrueType interpreter and free_buffer_in_size() is
invoked repeatedly.
2010-09-15 Werner Lemberg <wl@gnu.org>
Make bytecode debugging with FontForge work again.
* src/truetype/ttinterp.c (TT_RunIns): Don't call
`free_buffer_in_size' in case of error if a debugger is active.
2010-09-14 Werner Lemberg <wl@gnu.org>
Improve tracing messages.
* src/truetype/ttinterp.c (TT_RunIns): Improve wording of tracing
message.
* src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep): Add
tracing message.
* src/truetype/ttgload.c (tt_loader_init): Add tracing message.
* src/cache/ftcsbits.c (ftc_snode_load): Emit tracing message if
glyph doesn't fit into a small bitmap container.
2010-09-13 Werner Lemberg <wl@gnu.org>
Fix minor issues reported by <muktha.narayan@wipro.com>.
* src/autofit/aflatin.c (af_latin_compute_stem_width): Remove
redundant conditional check.
* src/base/ftsynth.c (FT_GlyphSlot_Embolden): Ditto.
* src/cff/cffload.c (cff_encoding_load): Remove conditional check
which always evaluates to `true'.
* src/pshinter/pshalgo.c (ps_glyph_interpolate_strong_points):
Ditto.
* src/truetype/ttinterp.c (Ins_IUP): Ditto.
* src/cid/cidgload.c (cid_slot_load_glyph): Don't check for NULL if
value is already dereferenced.
* src/winfonts/winfnt.c (FNT_Load_Glyph): Fix check of `face'.
2010-08-31 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Ignore the environmental setting of LIBTOOL.
Patch is suggested by Adrian Bunk, to prevent unexpected
reflection of environmental LIBTOOL. See:
http://savannah.nongnu.org/patch/?7290
* builds/unix/unix-cc.in: LIBTOOL is unconditionally set to
$(FT_LIBTOOL_DIR)/libtool. FT_LIBTOOL_DIR is set to $(BUILD_DIR)
by default.
* configure: When configured for the building out of source tee,
FT_LIBTOOL_DIR is set to $(OBJ_DIR).
2010-08-31 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
[truetype] Decrease the trace level catching the interpreter error.
* src/truetype/ttinterp.c (TT_RunIns): Decrease the trace level
showing the error when the interpreter returns with an error,
from FT_TRACE7() to FT_TRACE1().
2010-08-30 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
[truetype] Prevent bytecode reuse after the interpretation error.
* src/truetype/ttinterp.c (free_buffer_in_size): New function to
free the buffer allocated during the interpretation of this glyph.
(TT_RunIns): Unset FT_Face->size->{cvt_ready,bytecode_ready} if
an error occurs in the bytecode interpretation. The interpretation
of invalid bytecode may break the function definitions and referring
them in later interpretation is danger. By unsetting these flags,
`fpgm' and `prep' tables are executed again in next interpretation.
This fixes Savannah bug #30798, reported by Robert Święcki.
2010-08-29 Werner Lemberg <wl@gnu.org>
[ftraster] Pacify compiler.
* src/raster/ftraster.c (ft_black_new) [_STANDALONE_]: `memory' is
not used.
2010-08-29 Werner Lemberg <wl@gnu.org>
[cff] Allow SIDs >= 65000.
* src/cff/cffload.c (cff_charset_load): Fix change from 2009-03-20:
The threshold for SIDs is not applicable here. I misinterpreted the
`SID values 65000 and above are available for implementation use'
sentence in the CFF specification.
Problem reported by Ivan Ninčić <inincic@pdftron.com>.
2010-08-28 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Force hinting when the font lacks its familyname.
In Type42 or Type11 font embedded in PostScript & PDF, TrueType sfnt
stream may lack `name' table because they are not required. Hinting
for nameless fonts is safer for PDFs including embedded Chinese
fonts. Written by David Bevan, see:
http://lists.gnu.org/archive/html/freetype-devel/2010-08/msg00021.html
http://lists.freedesktop.org/archives/poppler/2010-August/006310.html
* src/truetype/ttobjs.c (tt_check_trickyness): If a NULL pointer by
nameless font is given, TRUE is returned to enable hinting.
2010-08-28 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Register yet another tricky TrueType font.
* src/truetype/ttobjs.c (tt_check_trickyness): Add `HuaTianKaiTi?',
a Kaishu typeface paired with `HuaTianSongTi?' by Huatian
Information Industry.
2010-08-17 Teijo Kinnunen <Teijo.Kinnunen@nuance.com>
Fix Savannah bug #30788.

Problem reported by malc <av1474@comtv.ru>.
* src/cff/cffgload.c (cff_decoder_parse_charstrings)

minimum character code passed by a legacy rogue client by...
* include/freetype/config/ftoption.h (FT_MAX_CHARMAP_CACHEABLE):
This. It is undefined when FT_CONFIG_OPTION_OLD_INTERNALS is
undefined (thus the rogue client compatibility is not required).
* src/cff/cffobjs.c (cff_face_init): Abort the automatic
selection or synthesis of Unicode cmap subtable when the charmap
index exceeds FT_MAX_CHARMAP_CACHEABLE.
* src/sfnt/ttcmap.c (tt_face_build_cmaps): Issue error message
when the charmap index exceeds FT_MAX_CHARMAP_CACHEABLE.

FT_MAX_CHARMAP_CACHEABLE, ignore it and search earlier one.
(FT_Select_Charmap): When a charmap matching with requested
encoding but after FT_MAX_CHARMAP_CACHEABLE, ignore and search
earlier one.
(FT_Set_Charmap): When a charmap matching with requested
charmap but after FT_MAX_CHARMAP_CACHEABLE, ignore and search
earlier one.
(FT_Get_Charmap_Index): When a requested charmap is found
after FT_MAX_CHARMAP_CACHEABLE, return the inverted charmap
index.

Additional fix for Savannah bug #30306.
* src/base/ftobjs.c (Mac_Read_POST_Resource): If the type of the
POST fragment is 0, the segment is completely ignored. The declared
length of the segment is not cared at all. According to Adobe
Technical Note 5040, type 0 segment is a comment only and should not
be loaded for the interpreter. Reported by Robert Święcki.
2010-07-01 Werner Lemberg <wl@gnu.org>

related to the bug fix but makes sense anyway.
2010-07-01 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Initial fix for Savannah bug #30306.
* src/base/ftobjs.c (Mac_Read_POST_Resource): Check `rlen', the
length of fragment declared in the POST fragment header, and prevent
an underflow in length calculation. Some fonts set the length to
zero in spite of the existence of a following 16bit `type'.

* src/sfnt/ttcmap.c (tt_face_build_cmaps): Improve check for pointer
to `cmap_table'.
2010-06-24 Werner Lemberg <wl@gnu.org>
Fix Savannah bug #30235.
* src/pfr/pfrgload.c (pfr_glyph_load_simple): Protect against
invalid indices if there aren't any coordinates for indexing.
2010-06-24 Werner Lemberg <wl@gnu.org>
[bdf]: Font properties are optional.
* src/bdf/bdflib.c (_bdf_readstream): Use special error code to
indicate a redo operation.
(_bdf_parse_start): Handle `CHARS' keyword here too and pass current
input line to `_bdf_parse_glyph'.
2010-06-23 Werner Lemberg <wl@gnu.org>
Fix Savannah bug #30220.
* include/freetype/fterrdef.h
(BDF_Err_Missing_Fontboundingbox_Field): New error code.
* src/bdf/bdflib.c (_bdf_parse_start): Check for missing
`FONTBOUNDINGBOX' field.
Avoid memory leak if there are multiple `FONT' lines (which is
invalid but doesn't hurt).
2010-06-21 Werner Lemberg <wl@gnu.org>
Fix Savannah bug #30168.
* src/pfr/pfrgload.c (pfr_glyph_load_compound): Limit the number of
subglyphs to avoid endless recursion.
2010-06-20 Werner Lemberg <wl@gnu.org>
Fix Savannah bug #30145.
* src/psaux/psobjs.c (t1_builder_add_contour): Protect against
`outline == NULL' which might happen in invalid fonts.
2010-06-19 Werner Lemberg <wl@gnu.org>
Fix Savannah bug #30135.
* src/bdf/bdflib.c (_bdf_list_join): Don't modify value in static
string `empty'.
(_bdf_parse_glyph): Avoid memory leak in case of error.
2010-06-15 Werner Lemberg <wl@gnu.org>
Fix Savannah bug #30108.
* src/autofit/afglobal.c (af_face_globals_compute_script_coverage):
Properly mask AF_DIGIT bit in comparison.
2010-06-11 Werner Lemberg <wl@gnu.org>
Fix Savannah bug #30106.
Point numbers for FreeType's implementation of hinting masks are
collected before the final number of points of a glyph has been
determined; in particular, the code for handling the `endchar'
opcode can reduce the number of points.
* src/pshinter/pshalgo.c (psh_glyph_find_strong_points): Assure that
`end_point' is not larger than `glyph->num_points'.
2010-06-11 Werner Lemberg <wl@gnu.org>
[cff]: Improve debugging output.
* src/cff/cffgload.c (cff_decoder_parse_charstrings)
<cff_op_hintmask>: Implement it.
2010-06-10 Graham Asher <graham.asher@btinternet.com>
ftgrays: Speed up rendering of small cubic splines.
* src/smooth/ftgrays.c (gray_render_cubic): Implement new,
simplified algorithm to find out whether the spline can be replaced
with two straight lines. See this thread for more:

against endless loop in case of corrupted font header data.
2010-05-26 Werner Lemberg <wl@gnu.org>
Remove unused variable.
Found by Graham.
* src/autofit/afhints.c (af_glyph_hints_reload): Remove unused
variable `first' in first block.
2010-05-22 Werner Lemberg <wl@gnu.org>
Fix various memory problems found by linuxtesting.org.
* src/base/ftgxval.c (FT_TrueTypeGX_Free, FT_ClassicKern_Free),
src/base/ftotval.c (FT_OpenType_Free), src/base/ftpfr.c
(ft_pfr_check): Check `face'.
* src/base/ftobjs.c (FT_Get_Charmap_Index): Check `charmap' and
`charmap->face'.

* src/cff/cffobjs.c (remove_subset_prefix): New function.
(cff_face_init): Use it to adjust `cffface->family_name'.
2010-05-20 Werner Lemberg <wl@gnu.org>
TrueType: Make FreeType ignore maxSizeOfInstructions in `maxp'.
Acroread does the same.
