+
+ [ftfuzzer] Replace `rand' with an xorshift algorithm.
+
+ * src/tools/ftfuzzer/ftfuzzer.cc: Don't include `stdlib.h'.
+ (Random): Implement and use a 32bit `xorshift' algorithm.
+
+2016-12-30 Werner Lemberg <wl@gnu.org>
+
+ [ftfuzzer] Restrict number of tested bitmap strikes.
+
+ Malformed fonts often have large values for the number of bitmap
+ strikes, and FreeType doesn't check the validity of all bitmap
+ strikes in advance.
+
+ Reported as
+
+ https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=353
+
+ * src/tools/ftfuzzer/ftfuzzer.cc: Include `stdlib.h' for `rand'.
+ (Random): Small class to provide n randomly selected numbers
+ (without repitition) out of the value set [1,N].
+ (LLVMFuzzerTestOneInput): Use it to test only up to 10 bitmap
+ strikes.
+
+2016-12-29 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Variation font API stability issues.
+
+ Make some functions work before a call to `TT_Set_MM_Blend'.
+
+ * src/truetype/ttgxvar.c (tt_hadvance_adjust): Exit immediately if
+ we don't blend.
+ (TT_Get_MM_Blend, TT_Get_Var_Design): Return default values if we

+
+2016-12-28 Werner Lemberg <wl@gnu.org>
+
+ [psnames] Only declare, not define, data in `pstables.h' (#49949).
+
+ Pdfium includes `pstables.h' a second time; moving the definition
+ from `pstables.h' to `psmodule.c' saves more than 60kByte data
+ segment space for this case.
+
+ * src/tools/glnames.py (StringTable::dump,
+ StringTable::dump_sublist, dump_encoding, dump_array): Emit
+ additional code to only define tables if `DEFINE_PS_TABLES' is set.

+ [truetype] Fix linear metrics of GX variation fonts (#49829).
+
+ When asking for an unhinted non-default variations,

+ [gzip] Improve building with external zlib (#49673).
+
+ Building FreeType with external zlib 1.2.8 makes msvc 14 stop with

+
+ ftgzip.c
+ zlib-1.2.8\zlib.h(86): error C2061:

+ ...
+ zlib-1.2.8\zlib.h(877): fatal error C1003:

+
+ The error happens because FreeType keeps an own copy of zlib-1.1.4
+ under `src/gzip'. When building `src/gzip/ftgzip.c' with
+ FT_CONFIG_OPTION_SYSTEM_ZLIB defined, it uses
+
+ #include <zlib.h>
+
+ which correctly finds an external `zlib.h', but `zlib.h' itself has
+ a line
+
+ #include "zconf.h"
+
+ which makes Visual Studio 2015 find `src/gzip/zconf.h' while
+ compiling the files in `src/gzip'.
+

+
+ [truetype] Introduce dynamic limits for some bytecode opcodes.
+
+ This speeds up FreeType's handling of malformed fonts.
+
+ * src/truetype/ttinterp.c (TT_RunIns): Set up limits for the number
+ of twilight points, the total number of negative jumps, and the
+ total number of loops in LOOPCALL opcodes. The values are based on

+
+ [truetype] Sanitize only last entry of `loca' table.
+
+ Without this patch, a loca sequence like `0 100000 0 100000 ...',
+ where value 100000 is larger than the `glyf' table size, makes
+ FreeType handle the whole `glyf' table as a single glyph again and
+ again, which is certainly invalid (and can be very slow, too).
+
+ * src/truetype/ttpload.c (tt_face_get_location): Implement.
+ Improve tracing messages.

+
+2016-09-11 Alexei Podtelezhnikov <apodtele@gmail.com>
+
+ [smooth] Fix valgrind warning and reoptimize.
+
+ The algorithm calls `gray_set_cell' at the start of each new contour
+ or when the contours cross the cell boundaries. Double-checking for
+ that is wasteful.
+
+ * src/smooth/ftgrays.c (gray_set_cell): Remove check for a new cell.

+
+ * src/sfnt/ttsbit.c (tt_face_load_strike_metrics): ... this function
+ can be used before and after setting up `sbit_strike_map'.
+ (tt_face_set_sbit_strike): Revert change.
+ (tt_sbit_decoder_init, tt_face_load_sbix_image): Map strike index.
+
+ * src/truetype/ttdriver.c (tt_size_select): Revert change.
+
+2016-09-09 Werner Lemberg <wl@gnu.org>
+
+ [ftfuzzer] Minor improvements.
+
+ * src/tools/ftfuzzer/ftfuzzer.cc (LLVMFuzzerTestOneInput): Ignore
+ invalid strikes.
+ Use better values for call to `FT_Set_Char_Size'.
+
+2016-09-09 Werner Lemberg <wl@gnu.org>
+
+ [sfnt] Don't provide (completely) broken strike data.
+
+ FreeType tries to sanitize strike header data; we now reject
+ completely broken ones.
+
+ * include/freetype/internal/tttypes.h (TT_FaceRec): New
+ `sbit_strike_map' array pointer.
+
+ * src/base/ftobjs.c (FT_Match_Size): Reject matches where either
+ width or height would be zero.
+ Add tracing message in case of error.
+
+ * src/sfnt/sfobjs.c (sfnt_load_face): Populate `sbit_strike_map',
+ only using (more or less) valid strike header data for
+ FT_Face's `available_sizes' array.
+ (sfnt_done_face): Updated.
+
+ * src/sfnt/ttsbit.c (tt_face_set_sbit_strike): Use
+ `sbit_strike_map'.
+ (tt_face_load_strike_metrics): Improve tracing.
+
+ * src/truetype/ttdriver.c (tt_size_select): Use `sbit_strike_map'.
+
2016-09-08 Werner Lemberg <wl@gnu.org>
* Version 2.7 released.
* src/tools/ftrandom/ftrandom.c (GOOD_FONTS_DIR): Provide better
default.
