Werner Lemberg 9d83d29028 Fix problem with T1_FIELD_{NUM,FIXED}_TABLE2.
* src/psaux/psobjs.c (ps_parser_load_field_table): Don't handle
`count_offset' if it is zero (i.e., unused).  Otherwise, the first
element of the structure which holds the data is erroneously
modified.  Problem reported by Chi Nguyen <chint@necsv.com>.

that should be a string or name is a string or name indeed. Avoid
memory leak if a keyword has been already encountered and its value
is overwritten.

* freetype2/src/type1/t1load.c: (T1_FieldRec): Adjust invocations of
T1_FIELD_XXX. (parse_dict): Ignore keywords that occur in the wrong
dictionary (e.g., in Private instead of FontDict).

* freetype2/src/type1/t1tokens.h: Adjust invocations of T1_FIELD_XXX.

        leak described in bug #16759.

        src/type1/t1gload.c:

          this is a major patch used to drastically improve the performance
          of loading glyphs. This both speeds up loading the glypn vector
          themselves and the auto-fitter.

          note that we've started using inline assembler with GCC to
          implement FT_MulFix, given that this function is so damn
          important for the engine's performance.

          the resulting speed-up is about 25%.

    for the cases where FT_NEW_ARRAY and FT_RENEW_ARRAY are not used
    already. Introducing the new FT_ALLOC_MULT and FT_REALLOC_MULT
    macros.

David Turner 264f307e66 * include/freetype/fterrdef.h, include/freetype/config/ftconfig.h,
include/freetype/internal/ftmemory.h, src/base/ftdbgmem.c,
    src/base/ftutil.c: udpating the memory management functions and
    macros to safely deal with array size buffer overflows, this
    corresponds to attemps 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
    will overflow and the array allocated will be 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, or make the engine crash later.

    the FT_ARRAY_NEW and FT_ARRAY_RENEW macro now check that the new
    count is no more than FT_INT_MAX/item_size, otherwise, a new error,
    named 'FT_Err_Array_Too_Large' will be returned.

    note that the memory debugger now works again when FT_DEBUG_MEMORY
    is defined, and FT_STRICT_ALIASING has disappeared, the corresponding
    code being now the default.

then exit.  Error handling or setting face->root is done later in
`sfnt_load_face'.
Pretty trace messages.

truetype module so that the code can be shared with the cff module.

This pass involves no real changes.  That is, the code is moved
verbatim mostly.  The only exception is the return value of
`tt_face_get_metrics'.

* src/sfnt/ttmtx.c, src/sfnt/ttmtx.h: Metrics-related tables' loading
and parsing code is moved here.
Move `tt_face_get_metrics' here from the truetype module.  The return
value is changed from `void' to `FT_Error'.

* include/freetype/internal/fttrace.h: New trace: ttmtx.

* src/truetype/ttpload.c, src/truetype/ttpload.h: `hdmx' loading and
parsing code is moved here.
New function `tt_face_load_prep' splitted from `tt_face_load_fpgm'.
`tt_face_load_fpgm' returns `FT_Err_Ok' if `fpgm' doesn't exist.

Werner Lemberg 59939244ad Implement new, simplified module selection. With GNU make it is now
sufficient to modify a single file, `modules.cfg', to control the
inclusion of modules and base extension files.

This change also fixes the creation of ftmodule.h; it now depends on
`modules.cfg' and thus is rebuilt only if necessary.

Finally, a version of `ftoption.h' in OBJ_DIR is preferred over the
default location.

* modules.cfg: New file.

* builds/freetype.mk: Don't include `modules.mk'.
Include all `rules.mk' files as specified in `modules.cfg'.
(FTOPTION_FLAG, FTOPTION_H): New variables.
(FT_CFLAGS): Add macro definition for FT_CONFIG_MODULES_H.
Add FTOPTION_FLAG.
($(FT_INIT_OBJ)): Don't use FT_MODULE_LIST.
(CONFIG_H): Add FTMODULE_H and FTOPTION_H.
(INCLUDES): Add DEVEL_DIR.
(INCLUDE_FLAGS, FTSYS_SRC, FTSYS_OBJ, FTDEBUG_SRC, FTDEBUG_OBJ,
OBJ_M, OBJ_S): Use `:=', not `='.
(remove_ftmodule_h): New phony target to delete `ftmodule.h'.
(distclean): Add remove_ftmodule_h.

* builds/modules.mk: (MODULE_LIST): Removed.
(make_module_list, clean_module_list): Replace targets
with...
(FTMODULE_H_INIT, FTMODULE_H_CREATE, FTMODULE_H_DONE): New
variables.  Reason for the change is that it is not possible to have
a phony prerequisite which is run only if the target file must be
rebuilt (phony prerequisites act like subroutines and are *always*
executed).  We only want to rebuild `ftmodule.h' if `module.cfg' is
changed.
Update all callers.
($FTMODULE_H)): Rule to create `ftmodule.h', depending on
`modules.cfg'.

* builds/toplevel.mk: Rewrite and simplify module handling.
(MODULES_CFG, FTMODULE_H): New variables.
Include MODULES_CFG.
(MODULES): New variable to include all `module.mk' and `rules.mk'
files.  We no longer use make's `wildcard' function for this.

* Makefile (USE_MODULES): Remove.  Update all users.
(OBJ_DIR): Define it here.

* src/*/module.mk: Change

    make_module_list: foo
    foo: ...

to

    FTMODULE_H_COMMANDS += FOO
    define FOO
    ...
    endef

in all files.  `FTMODULE_H_COMMANDS' is used in `FTMODULE_H_CREATE'.

* src/base/rules.mk (BASE_EXT_SRC): Use BASE_EXTENSIONS.

* builds/unix/detect.mk (setup): Always execute `configure' script.
(have_mk): Rename to...
(have_Makefile): This.
Don't use `strip' function.

* builds/unix/unix.mk: Include `install.mk' only if BUILD_PROJECT is
defined.
(have_mk): Don't use `strip' function.
Test for unix-def.mk in OBJ_DIR, not BUILD_DIR (and invert the test
accordingly).

* builds/unix/install.mk (install, uninstall): Handle `ftmodule.h'.

* builds/os2/os2-dev.mk, builds/unix/unix-dev.mk,

David Turner 6a681fa84a * src/autofit/afwarp.c: simple #ifdef to prevent compilation when
the warp hinter isn't active (it shouldn't, still experimental)

    * Jamfile, include/freetype/config/ftmodule.h: removed "gxvalid"
    and "otvalid" from the list of modules that are linked statically
    to a given FreeType library. Functionality has been moved to the
    "ftvalid" CVS module.

    note also that current Make-based build system still compiles the
    modules though...

    * include/freetype/config/ftoption.h: added FT_STRICT_ALIASING,
    which controls the definitions of the memory management functions
    to avoid warnings with recent versions of GCC. this macro is
    only here to be disabled, in case we detect problems with the
    new scheme.

    NOTE: disable macro to use the memory debugger. this will be fixed
          later !!

request, in fractional pixels.

* include/freetype/internal/ftobjs.h (FT_Select_Metrics,
FT_Request_Metrics), src/base/ftobjs.c (FT_Select_Metrics,
FT_Request_Metrics): New base functions to set the font metrics.  They
were part of FT_Select_Size/FT_Request_Size and are made independent
functions so that metrics are not set again and again.

* src/base/ftobjs.c (FT_Select_Size, FT_Request_Size): Metrics are set
only when driver's size_select/size_request is NULL.  That is, drivers
should set the metrics themselves.

does cause some problems without rounding.

s/index/strike_index/.
The scaled metrics are always preferred over strikes' metrics, even
when some strike is selected.  This is done because the strikes'
metrics are not reliable, e.g., the sign of the descender is wrong for
some fonts.

tt_face_load_strike_metrics), src/sfnt/ttsbit0.c
(tt_face_load_sbit_strikes, tt_face_load_strike_metrics): The

Werner Lemberg 92aa527a1c * builds/amiga/makefile.os4 (WARNINGS), builds/compiler/gcc-dev.mk
(CFLAGS), builds/compiler/gcc.mk (CFLAGS): Remove
-fno-strict-aliasing.


Say you have `(Foo*)x' and want to assign, pass, or return it as
`(Bar*)'.  If you simply say `x' or `(Bar*)x', then the C compiler
would warn you that type casting incompatible pointer types breaks
strict-aliasing.  The solution is to cast to `(void*)' instead which
is the generic pointer type, so the compiler knows that it should
make no strict-aliasing assumption on `x'.  But the problem with
`(void*)x' is that seems like in C++, unlike C, `void*' is not a
generic pointer type and assigning `void*' to `Bar*' without a cast
causes an error.  The solution is to cast to `Bar*' too, with
`(Bar*)(void*)x' as the result -- this is what the patch does.

* include/freetype/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP),
include/freetype/cache/ftcmru.h (FTC_MRULIST_LOOKUP_CMP): Remove
cast on lvalue, use a temporary pointer instead.

2005-03-15 23:31:48 +00:00
David Turner 68df4f732d * src/bdf/bdflib.c: various improvements to the bdf loader, mainly
used to reduce the amount of heap size required to only test wether
    we're dealing with a BDF font (the old code allocated 64 Kb right
    before any test).

    * src/lzw/ftlzw.c (FT_Stream_OpenLZW): modified the function to check
    the LZW header before doing anything else. This helps avoid un-necessary
    heap allocations (400 Kb of heap memory for the LZW decoder ! Oh my !)

    * src/gzip/ftgzip.c (FT_Stream_OpenGZip): ditto for the .gz decoder,
    though the code savings is smaller.

  heap-optimized embedded bitmap loader. This one also fixes bug #12107

  * src/sfnt/sfobjs.c: fixed bug that prevented loading SFNT fonts without
  a 'kern' table.
2005-02-28 22:09:07 +00:00
David Turner e5680279b2 * many, many files: several memory optimizations were implemented to
drastically reduce the heap usage of FreeType, especially in the case
  of memory-mapped files. The idea is to avoid loading and decoding tables
  in the heap, and instead access the raw data whenever possible (i.e.
  when it doesn't compromise performance).

  This had several impacts: first, opening vera.ttf uses a ridiculous amount
  of memory (when the FT_Library footprint is accounted for), until you start
  loading glyphs. Even then, you'll save at least 20 Kb compared to the non
  optimized case. performance of various operations, including open/close
  has also been dramatically improved.

  More optimisations to come. The auto-hinter eats memory like crazy? This
  must be stopped...

    added the temporary configuration FT_OPTIMIZE_MEMORY to control various
    optimizations used to reduce the heap footprint of memory-mapped TrueType
    files.

    * src/truetype/ttpload.c (tt_face_load_loca, tt_face_get_location,
    tt_face_done_loca): when FT_OPTIMIZE_MEMORY is set, the locations table
    is read directly from memory-mapped streams, instead of being decoded
    into the heap.

    * src/truetype/ttpload.c: only load the CVT and fpgm tables when the
    bytecode interpreter is compiled in.
2005-02-22 16:53:06 +00:00
David Turner 3e26d07e60 * src/base/ftdbgmem.c: adding the ability to list all allocation sites
in the memory debugger. Also a new function FT_DumpMemory() was added.
	It is only available in builds with FT_DEBUG_MEMORY defined, and you
	must declare it in your own code to use it, i.e. with something
	like:

	  extern void FT_DumpMemory( FT_Memory );

	  ...

	  FT_DumpMemory( memory );

	* include/freetype/config/ftoptions.h: disabling TrueType bytecode
	interpreter !

	* include/freetype/internal/ftmemory.h: adding FT_ARRAY_ZERO, as a
	convenience macro.
