This makes it easier to control the commits.

* src/autofit/aflatin.c (af_latin_metrics_init_blues): Add dummy
loop.  No functional change.
2015-12-06 18:18:02 +01:00
Werner Lemberg f45c0bf963 [autofit] Use string of standard characters.
This is more flexible; additionally, it would allow character
clusters.

* src/autofit/aftypes.h (SCRIPT, AF_DEFINE_SCRIPT_CLASS): Updated.
(AF_ScriptClassRec): Replace `standard_char[123]' with
`standard_charstring'.

* src/autofit/afscript.h: Replace last three character arguments
of the `SCRIPT' calls with a string parameter, holding the standard
characters (in UTF-8 encoding) separated with spaces.

* src/autofit/afglobal.c, src/autofit/afglobal.h,
src/autofit/afpic.c, src/autofit/afranges.c, src/autofit/hbshim.c
(SCRIPT): Updated.

* src/autofit/afcjk.c (af_cjk_metrics_init_widths),
src/autofit/aflatin.c (af_latin_metrics_init_widths): Updated.

for supporting character clusters in `afblue.dat'.

We need the computed standard horizontal and vertical widths for the
emboldening calculation.  This method provides a convenient way to
extract it from writing-system-specific metrics structures, which
all script definitions must implement.

* src/autofit/aftypes.h (AF_WritingSystem_GetStdWidthsFunc): New
function type.

Werner Lemberg 6bda921da0 [ftfuzzer] Update README file. 2015-11-02 06:53:48 +01:00
Werner Lemberg bcf618b256 [ftfuzzer] Add support for multiple files (patch #8779).
Currently, libFuzzer only supports mutation of a single file.  We
circumvent this problem by using an uncompressed tar archive as
multiple-file input for the fuzzer.

This patch enables tests of `FT_Attach_Stream' and AFM/PFM parsing;
a constructed tarball should contain a font file as the first
element, and files to be attached as further elements.

* src/tools/ftfuzzer/ftfuzzer.cc: Include libarchive headers.
(archive_read_entry_data, parse_data): New functions.
(LLVMFuzzerTestOneInput): Updated.

* src/tools/ftfuzzer/ftmutator.cc: New file, providing a custom
mutator for libFuzzer that can mutate tarballs in a sensible way.
