2006-05-12 Werner Lemberg <wl@gnu.org>
* Version 2.2.1 released.
=========================
Tag sources with `VER-2-2-1'.
2006-05-12 Werner Lemberg <wl@gnu.org>
* src/tools/docmaker/sources.py (re_source_keywords): Add word
boundary markers.
* src/tools/docmaker/content.py (re_field): Allow `.' in field names
(but not at the beginning or end).
* src/tools/docmaker/tohtml.py (html_header_1): Use `utf-8' charset.
(block_footer): Split into...
(block_footer_start, block_footer_middle, block_footer_end): This to
add navigation buttons.
(HtmlFormatter::block_exit): Updated.
* include/freetype/*: Many minor documentation improvements (adding
links, spelling errors, etc.).
2006-05-11 Werner Lemberg <wl@gnu.org>
* README: Minor updates.
* include/freetype/*: s/scale/scaling value/ where appropriate.
Many other minor documentation improvements.
* src/tools/docmaker/sources.py (re_italic, re_bold): Handle
trailing punctuation.
* src/tools/docmaker/tohtml.py (HtmlFormatter::make_html_word): Add
warning message for undefined cross references.
Update handling of re_italic and re_bold.
2006-05-11 Masatake YAMATO <jet@gyve.org>
* builds/unix/ftsystem.c (FT_Stream_Open): Check errno only if
read system call returns -1.
Remove a redundant parenthesis.
2006-05-10 Werner Lemberg <wl@gnu.org>
* builds/unix/ftsystem.c (FT_Stream_Open): Avoid infinite loop if
given an empty, un-mmap()able file. Reported and suggested fix in
Savannah bug #16555.
* builds/freetype.mk (refdoc): Write-protect the `docmaker'
directory to suppress generation of .pyc files. According to the
Python docs there isn't a more elegant solution (currently).
* builds/toplevel.mk (dist): New target which builds .tar.gz,
.tar.bz2, and .zip files. Note that the version number is still
hard-coded.
(do-dist): Sub-target of `dist'.
(CONFIG_GUESS, CONFIG_SUB): New variables.
(.PHONY): Updated.
2006-05-09 Rajeev Pahuja <rpahuja@esri.com>

2006-05-07 Werner Lemberg <wl@gnu.org>
Put version information into the configure script. Reported by Paul
Watson <pwatson@redlinepy.com>.
* builds/unix/configure.ac: Renamed to...
* builds/unix/configure.raw: This which now serves (with appropriate
modifications) as a template for configure.ac.
* version.sed: New script.
* autogen.sh: Generate configure.ac from configure.raw, using
FREETYPE_MAJOR, FREETYPE_MINOR, and FREETYPE_PATCH from freetype.h.
2006-05-06 Werner Lemberg <wl@gnu.org>

Allow compilation again with C++ compilers.
* include/freetype/internal/ftmemory.h (FT_ASSIGNP,
FT_ASSIGNP_INNER): New macros which do the actual assignment, and
which exist in two variants (for C and C++).
Update callers accordingly.
2006-05-03 Werner Lemberg <wl@gnu.org>
* include/freetype/config/ftoption.h (FT_STRICT_ALIASING): Removed.
2006-05-02 Werner Lemberg <wl@gnu.org>

`-Wstrict-prototypes'.
* src/base/ftstream.c (FT_Stream_EnterFrame): Add cast.
* include/freetype/config/ftconfig.h (FT_BASE_DEF) [__cplusplus]:
Remove `extern'.
2006-05-02 David Turner <david@freetype.org>
Update the memory management functions and macros to safely deal
with array size buffer overflows. This corresponds to attempts to
allocate arrays that are too large. For an example, consider the
following code:
count = read_uint32_from_file(); array = malloc( sizeof ( Item ) *
count ); for ( nn = 0; nn < count; nn++ )
array[nn] = read_item_from_file();
If `count' is larger than `FT_UINT_MAX/sizeof(Item)', the
multiplication overflows, and the array allocated os smaller than
the data read from the file. In this case, the heap will be
trashed, and this can be used as a denial-of-service attack, or make
the engine crash later.
The FT_ARRAY_NEW and FT_ARRAY_RENEW macros now ensure that the new
count is no larger than `FT_INT_MAX/item_size', otherwise a new
error code `FT_Err_Array_Too_Large' will be returned.
Note that the memory debugger now works again when FT_DEBUG_MEMORY
is defined. FT_STRICT_ALIASING has disappeared; the corresponding
code is now the default.
* include/freetype/config/ftconfig.h (FT_BASE_DEF) [!__cplusplus]:
Don't use `extern'.
* include/freetype/fterrdef.h (FT_Err_Array_Too_Large): New error
code.
* include/freetype/internal/ftmemory.h (FT_DEBUG_INNER)
[FT_DEBUG_MEMORY]: New macro.
(ft_mem_realloc, ft_mem_qrealloc): Pass new object size count also.
(ft_mem_alloc_debug, ft_mem_qalloc_debug, ft_mem_realloc_debug,
ft_mem_qrealloc_debug, ft_mem_free_debug): Removed.
(FT_MEM_ALLOC, FT_MEM_REALLOC, FT_MEM_QALLOC, FT_MEM_QREALLOC,
FT_MEM_FREE): Redefine.
(FT_MEM_NEW_ARRAY, FT_MEM_RENEW_ARRAY, FT_MEM_QNEW_ARRAY,
FT_MEM_QRENEW_ARRAY): Redefine.
(FT_ALLOC_MULT, FT_REALLOC_MULT, FT_MEM_QALLOC_MULT,

src/cache/ftcmru.h: This new location.
Update declarations according to the changes in the corresponding
source files.
Note that these files are not used by FreeType clients; all public
APIs of the cache module have been already moved to
`include/freetype/ftcache.h', and all FT_CACHE_INTERNAL_XXXX_H
macros resolve to it.
Reason for the move is to allow modifications of the internals
without interferences with rogue clients. Note that there are no
known clients that access the cache internals at the moment.
* builds/unix/install.mk (install): Don't install headers from
$(CACHE_H).

but include the headers directly (which are now in `src/cache').
* src/cache/ftccache.c: Don't use the FT_CACHE_INTERNAL_XXX_H
macros but include the headers directly.
(FTC_Cache_Init, FTC_Cache_Done, FTC_Cache_NewNode,
FTC_Cache_Lookup, FTC_Cache_RemoveFaceID): Declare as FT_LOCAL_DEF.
* src/cache/ftccache.c: Don't use the FT_CACHE_INTERNAL_XXX_H
macros but include the headers directly.

* src/cache/ftcmanag.c (FTC_Manager_Lookup_Size): Prevent crashes in
Mozilla/FireFox print preview in Ubuntu Hoary.
2006-02-28 Chia-I Wu <b90201047@ntu.edu.tw>

order so that type42 module is removed before truetype module. This
avoids double free in some occasions.

[FT_CONFIG_OPTION_OLD_INTERNALS]: Remove declaration of
ftc_node_done.
* src/cache/ftccache.c (ftc_node_destroy)

2006-02-27 David Turner <david@freetype.org>
* src/base/ftutil.c (ft_mem_alloc, ft_mem_qalloc, ft_mem_realloc,
ft_mem_qrealloc): Return an error if a negative size is passed in
parameters.
* src/cache/ftccache.c (ftc_node_destroy): Mark as FT_BASE_DEF since
it needs to be exported for rogue clients.
* src/pshinter/pshglob.c (psh_blues_set_zones_0): Prevent problems
with malformed fonts which have an odd number of blue values (these
are broken according to the specs).

height are not too small or too large, just like we were doing in
2.1.10.
* src/autofit/afloader.c (af_loader_load_g): The vertical metrics
are not scaled.
2006-02-26 Werner Lemberg <wl@gnu.org>

* docs/CHANGES: Updated to reflect many fixes for backward
compatibility. Still incomplete.
2006-02-26 David Turner <david@freetype.org>
* src/base/ftobjs.c (ft_recompute_scaled_metrics): Re-enable
conservative rounding of metrics to avoid breaking clients like

2006-02-25 Werner Lemberg <wl@gnu.org>
* devel/ftoption.h: Synchronize with
include/freetype/config/ftoption.h.

* include/freetype/config/ftoption.h (FT_STRICT_ALIASING): Don't
define for C++.

FT_OPENTYPE_VALIDATE_H but FT_INTERNAL_VALIDATE_H.
* include/freetype/internal/services/svpfr.h: Include FT_PFR_H.

* src/base/ftoutln.c (FT_OUTLINE_GET_CONTOUR, ft_contour_has,
ft_contour_enclosed, ft_outline_get_orientation): Commented out. We
have to wait until `FT_GlyphSlot_Own_Bitmap' is stabilized.
(FT_Outline_Embolden): Use `FT_Outline_Get_Orientation'.
2006-02-24 Chia-I Wu <b90201047@ntu.edu.tw>
* include/freetype/ftbitmap.h (FT_Bitmap_Embolden): Update
documentation.
* include/freetype/ftsynth.h (FT_GlyphSlot_Own_Bitmap),
src/base/ftsynth.c (FT_GlyphSlot_Own_Bitmap): New function to make
sure a glyph slot owns its bitmap. It is also marked experimental
and due to change.
(FT_GlyphSlot_Embolden): Undo the last change. It turns out that
rendering the outline confuses some applications.
2006-02-24 David Turner <david@freetype.org>
* Release candidate VER-2-2-0-RC3.
----------------------------------
* src/cache/ftcbasic.c: Correct compatibility hack bug.

New request type `FT_SIZE_REQUEST_TYPE_SCALES' to specify the scales
directly.
2006-02-23 David Turner <david@freetype.org>
Two BDF patches from Debian libfreetype6 for 2.1.10.
* src/bdf/bdflib.c (_bdf_parse_glyphs): Fix a bug with zero-width
glyphs.
Fix a problem with large encodings.
Fix binary compatibility issues for gnustep-back (GNUstep backend
module) which still crashes under Sarge.

FTC_OldCMapDesc) [FT_CONFIG_OPTION_OLD_INTERNALS]: New data
structures and enumerations.
(FTC_CMapCache_Lookup) [FT_CONFIG_OPTION_OLD_INTERNALS]: New
compatibility code.
* src/cache/ftcbasic.c: Fix a silly bug that prevented our `hack' to
support rogue clients compiled against 2.1.7 to work correctly.
This probably explains the GNUstep crashes with the second release
candidate.
2006-02-23 Chia-I Wu <b90201047@ntu.edu.tw>
* include/freetype/ftoutln.h (enum FT_Orientation): New value
`FT_ORIENTATION_NONE'.
* src/base/ftoutln.c (FT_OUTLINE_GET_CONTOUR, ft_contour_has,
ft_contour_enclosed, ft_outline_get_orientation): Another version of
`FT_Outline_Get_Orientation'. This version differs from the public
one in that each part (contour not enclosed in another contour) of the
outline is checked for orientation.
(FT_Outline_Embolden): Use `ft_outline_get_orientation'.
* src/base/ftsynth.c (FT_GlyphSlot_Embolden): Render the outline and
use bitmap's embolden routine when the outline one failed.
2006-02-22 Chia-I Wu <b90201047@ntu.edu.tw>
* modules.cfg: Compile in ftotval.c and ftxf86.c by default for ABI
compatibility.

* src/sfnt/ttsbit0.c (tt_sbit_decoder_load_bit_aligned,
tt_sbit_decoder_load_byte_aligned) [FT_OPTIMIZE_MEMORY]: Fix sbit
loading. (Only tested with bit aligned sbit with x_pos == 0.)
* src/truetype/ttpload.c (tt_face_load_hdmx,
tt_face_get_device_metrics) [FT_OPTIMIZE_MEMORY]: `hdmx' is not
actually used.
2006-02-21 David Turner <david@freetype.org>
Add a new API named FT_Get_TrueType_Engine_Type to determine whether
we have a patented, unpatented, or unimplemented TrueType bytecode
interpreter.
The FT_Get_Module_Flags API was removed consequently.
* include/freetype/ftmodapi.h (FT_Module_Get_Flags): Removed.
Replaced with...

embedded bitmaps from being correctly listed and used.
* src/sfnt/ttmtx.c (tt_face_load_hmtx): Disable memory optimization
if FT_CONFIG_OPTION_OLD_INTERNALS is used. The is necessary because
libXfont is directly accessing the HMTX data, unfortunately.
Fix some compiler warnings.
(tt_face_get_metrics): Ditto.
* src/pfr/pfrsbit.c (pfr_slot_load_bitmap): Fix handling of
character advances.
2006-02-20 David Turner <david@freetype.org>
Support binary compatibility with the X.Org server's Xfont library.
Note that this change unfortunately prevents memory optimizations
for the embedded bitmap loader.
* include/freetype/internal/sfnt.h (SFNT_Interface): Move
`set_sbit_strike' and `load_sbit_metrics' fields to the location of
version 2.1.8.
* src/sfnt/sfdriver.c (tt_face_set_sbit_strike_stub): Call
FT_Size_Request.
(sfnt_interface): Updated.
* src/sfnt/ttsbit.c [FT_CONFIG_OPTION_OLD_INTERNALS]: Don't load

[FT_CONFIG_OPTION_OLD_INTERNALS]: Try to revive old functions of the
cache sub-system. We try to recognize old legacy signatures with a
gross hack (hope it works).
2006-02-17 Werner Lemberg <wl@gnu.org>
* devel/ftoption.h: Synchronize with
include/freetype/config/ftoption.h.
2006-02-16 David Turner <david@freetype.org>
Massive changes to the internals to respect the internal object
layouts and exported functions of FreeType 2.1.7. Note that the
cache sub-system cannot be fully retrofitted, unfortunately.
* include/freetype/config/ftoption.h
(FT_CONFIG_OPTION_OLD_INTERNALS): New macro.

Use FT_CONFIG_OPTION_OLD_INTERNALS to revive old functions and data
structures.
Move newly added structure elements to the end of the affected
structure and add stub fields (if FT_CONFIG_OPTION_OLD_INTERNALS is
defined) to assure binary compatibility with older FreeType
versions.
Use FT_CONFIG_OPTION_OLD_INTERNALS to add function stubs for old
functions:
ft_stub_set_char_sizes
ft_stub_set_pixel_sizes
Rename the following internal functions to provide the old function
names as stubs:
FT_Alloc -> ft_mem_alloc
FT_QAlloc -> ft_mem_qalloc
FT_Realloc -> ft_mem_realloc
FT_QRealloc -> ft_mem_qrealloc
FT_Free -> ft_mem_free
FT_Alloc_Debug -> ft_mem_alloc_debug
FT_QAlloc_Debug -> ft_mem_qalloc_debug
FT_Realloc_Debug -> ft_mem_realloc_debug
FT_QRealloc_Debug -> ft_mem_qrealloc_debug
FT_Free_Debug -> ft_mem_free_debug

* include/freetype/internal/ftobjs.h (FT_Face_InternalRec): Remove
unused `max_points' and `max_contours'.
* src/cid/cidobjs.c (cid_face_init), src/type1/t1objs.c
(T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Update.
* include/freetype/internal/tttypes.h (TT_FaceRec): Remove unused
`max_components'.
* src/truetype/ttinterp.h (TT_ExecContextRec): Remove unused
`loadSize' and `loadStack'.
* src/truetype/ttinterp.c (TT_Done_Context, TT_Load_Context),
src/sfnt/ttload.c (tt_face_load_maxp): Update.
* src/cff/cffobjs.h (cff_size_select), src/sfnt/sfdriver.c
(sfnt_interface), src/truetype/ttdriver.c (tt_size_request): Fix
compiler errors/warnings when TT_CONFIG_OPTION_EMBEDDED_BITMAPS is not
defined.
* src/sfnt/ttmtx.c (tt_face_load_hmtx, tt_face_get_metrics): Fix
possible segment faults for the non-FT_OPTIMIZE_MEMORY'ed versions.
(finally!)
For most OpenType tables, `tt_face_load_xxxx' simply loads the table
and `face->root' is set later in `sfnt_load_face'. Here, we try to
make this work for _all_ tables. Also improve tracing messages.
* src/sfnt/ttsbit.c, src/sfnt/ttsbit0.c, src/sfnt/ttload.c,
src/sfnt/ttmtx.c: all `tt_face_load_xxxx' should load the table and
then exit. Error handling or setting face->root is done later in
`sfnt_load_face'.
* src/sfnt/sfobjs.c (sfnt_load_face): Work harder.
Mac bitmap-only fonts are not scalable.
Check that `face->header.Units_Per_EM' is not zero.
(LOAD_, LOADM_): Emit pretty trace messages.
* src/sfnt/ttsbit0.c (tt_face_load_strike_metrics): Read metrics
from `eblc'.
* src/sfnt/ttcmap.c (tt_face_build_cmaps), src/sfnt/ttpost.c
(load_format_20, load_format_25, tt_face_get_ps_name): Use
face->max_profile.numGlyphs, instead of face->root.num_glyphs.
2006-02-14 Werner Lemberg <wl@gnu.org>
* include/freetype/ftoutln.h (FT_Outline_Embolden): Mention in
documentation that negative strength values are possible.
Give an example call.
* include/freetype/freetype.h (FT_GlyphSlotRec): Improve
documentation of `outline' field.
* src/sfnt/sfobjs.c: Include FT_INTERNAL_DEBUG_H.
* src/sfnt/sfdriver.c: Include ttmtx.h.
* src/autofit/afcjk.c: Include aftypes.h and aflatin.h.
2006-02-14 Chia-I Wu <b90201047@ntu.edu.tw>
* src/sfnt/ttmtx.c (tt_face_get_metrics): Typo.
2006-02-14 Chia-I Wu <b90201047@ntu.edu.tw>
* src/sfnt/ttmtx.c (tt_face_load_hhea, tt_face_load_hmtx): Simply
return error if table is missing.
Check table length in non-FT_OPTIMIZE_MEMORY'ed `tt_face_load_hmtx'.
* src/sfnt/sfobjs.c (sfnt_load_face): Take care of missing metrics
tables. The last change makes Mac bitmap-only font not load and
this fixes it.
* src/truetype/ttgload.c (load_truetype_glyph): Fix compilation
error when FT_CONFIG_OPTION_INCREMENTAL is defined.
2006-02-13 Chia-I Wu <b90201047@ntu.edu.tw>
Clean up the SFNT_Interface. In this final pass, `load_hmtx' is
split from `load_hhea'.
* include/freetype/internal/sfnt.h, src/sfnt/sfdriver.c,
src/sfnt/ttmtx.c, src/sfnt/ttmtx.h: Split `hmtx' from `hhea'.
* src/sfnt/sfobjs.c (sfnt_load_face): Update.
2006-02-13 Chia-I Wu <b90201047@ntu.edu.tw>
* src/sfnt/ttmtx.h, src/sfnt/ttmtx.c: Why are there two copies of
code...
2006-02-13 Chia-I Wu <b90201047@ntu.edu.tw>
Clean up the SFNT_Interface. In this pass, we want to treat the
font directory (offset table and table directory) as a normal table
like the others. This also means that TTCs are no longer recognized
there but in `init_face'.
* include/freetype/internal/sfnt.h (SFNT_Interface),
src/sfnt/sfdriver.c: `load_sfnt_header' and `load_directory' are
combined and renamed to `load_font_dir'.
* src/sfnt/ttload.h, src/sfnt/ttload.c:
s/sfnt_dir_check/check_table_dir/.
`sfnt_init' is moved to sfobjs.c and renamed to `sfnt_open_font'.
`tt_face_load_sfnt_header' and `tt_face_load_directory' are combined
and renamed to `tt_face_load_font_dir'.
* src/sfnt/sfobjs.c (sfnt_init_face): Recognize TTC here.
2006-02-13 Chia-I Wu <b90201047@ntu.edu.tw>
Clean up the SFNT_Interface. Table loading functions are now named
after the tables' tags; `hdmx' is TrueType-specific and thus the
code is moved to the truetype module; `get_metrics' is moved here
from the truetype module so that the code can be shared with the cff
module.
