changelog.22

ReactOS是一些高手根据Windows XP的内核编写出的类XP。内核实现机理和API函数调用几乎相同。甚至可以兼容XP的程序。喜欢研究系统内核的人可以看一看。

	* builds/unix/unixddef.mk: Actually do define PLATFORM (fixing
	change from 2006-01-31).
	(TOP_DIR, OBJ_DIR): Update.

	* builds/unix/install.mk (install): Fix path for ftmodule.h.

	* Makefile, *.mk, builds/unix/unix-cc.in, builds/unix-def.in: Use
	`?=' where appropriate.

	* builds/detect.mk (TOP_DIR), builds/os2/os2-dev.mk (TOP_DIR),
	builds/win32/w32-dev.mk (TOP_DIR): Removed.  Defined elsewhere.

2006-01-31  Werner Lemberg  <[e-mail]>

	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,
	builds/win32/w32-bccd.mk, builds/win32/w32-dev.mk: Don't define
	BUILD_DIR but DEVEL_DIR for development header files.

	* builds/ansi/ansi-def.mk (TOP_DIR, OBJ_DIR),
	builds/beos/beos-def.mk (TOP_DIR, OBJ_DIR), builds/unix/unix-def.in
	(TOP_DIR, OBJ_DIR): Removed.  Defined elsewhere.

	* builds/dos/dos-def.mk (OBJ_DIR), builds/os2/os2-def.mk (OBJ_DIR),
	builds/win32/win32-def.mk (OBJ_DIR): Removed.  Defined elsewhere.

	* builds/unix/unixddef.mk: Don't define BUILD_DIR but DEVEL_DIR for
	development header files.
	Don't define PLATFORM.

	* configure: Copy `modules.cfg' to builddir if builddir != srcdir.
	Update snippet taken from autoconf's m4sh.m4 to current CVS version.
	Be more verbose.

	* include/freetype/config/ftmodule.h: Add comments -- this file is
	no longer used if FreeType is built with GNU make.

	* docs/CHANGES, docs/CUSTOMIZE, docs/INSTALL, docs/INSTALL.ANY,
	docs/INSTALL.GNU, docs/INSTALL.UNX: Document new build mechanism.
	Other minor updates.

	* modules.txt: Removed.  Contents included in `modules.cfg'.


	* include/freetype/internal/ftmemory.h (FT_QAlloc_Debug,
	FT_Free_Debug) [FT_STRICT_ALIASING]: Fix typos.

	* src/base/ftdbgmem.c (FT_Alloc_Debug, FT_Realloc_Debug,
	FT_QAlloc_Debug, FT_QRealloc_Debug, FT_Free_Debug)
	[FT_STRICT_ALIASING]: Implement.

2006-01-31  Chia-I Wu  <[e-mail]>

	* src/cff/cffobjs.c (cff_face_init), src/cid/cidobjs.c
	(cid_face_init), src/pfr/pfrobjs.c (pfr_face_init),
	src/type1/t1objs.c (T1_Face_Init): Set face->height to MAX(1.2 *
	units_per_EM, ascender - descender).

2006-01-31  Chia-I Wu  <[e-mail]>

	* include/freetype/internal/t1types.h (AFM_FontInfo),
	src/psaux/afmparse.c, src/tools/test_afm.c: Read `FontBBox',
	`Ascender', and `Descender' from an AFM.

	* src/type1/t1afm.c (T1_Read_Metrics): Use the metrics from the AFM.

	* include/freetype/freetype.h (FT_FaceRec): Mention that fields may
	be changed after file attachment.

2006-01-28  Werner Lemberg  <[e-mail]>

	* src/*/module.mk (.PHONY): Add.

2006-01-27  Werner Lemberg  <[e-mail]>

	* README, docs/FTL.TXT: Fix email address for bug reports.
	Other minor formatting.

	* devel/ftoption.h: Synchronize with
	include/freetype/config/ftoption.h.

	* src/autofit/module.mk (add_autofit_module), src/bdf/module.mk
	(add_bdf_module), src/type42/module.mk (add_type42_driver): Fix
	whitespace.

	* src/smooth/module.mk (add_smooth_renderer): Add lcd and lcdv
	renderer classes.

2006-01-27  David Turner  <[e-mail]>

	* builds/unix/configure.ac: Fix build problem on Cygwin.

	* builds/unix/install.mk (install): Don't install the internal
	headers, and remove existing ones if found in the target install
	directory.

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

	* Jamfile, include/freetype/config/ftmodule.h: Remove `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 (FT_STRICT_ALIASING): New macro
	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!

	* include/freetype/internal/ftmemory.h, src/base/ftutil.c (FT_Alloc,
	FT_QAlloc, FT_Realloc, FT_QRealloc, FT_Free) [FT_STRICT_ALIASING]:
	New versions.


	* builds/win32/visualc/freetype.dsp: Updating project file to
	define FT2_BUILD_LIBRARY, and remove gxvalid + otvalid modules from
	compilation.


	* builds/freetype.mk (FT_CFLAGS), Jamfile (DEFINES): Define the
	macro FT2_BUILD_LIBRARY when compiling the library.

	* include/freetype/config/ftheader.h: Remove inclusions of internal
	headers except if the macro FT2_BUILD_LIBRARY is defined.


	* include/freetype/internal/psaux.h (AFM_KernPair, AFM_TrackKern,
	AFM_FontInfo): Move structure declarations to...
	* include/freetype/internal/t1types.h: This file.


	* (many files): Fix compiler warnings.
	Various minor reorganizations.


	* src/cff/cffload.c (cff_font_done): Don't free static array
	`subfonts'.

	* src/otvalid/otvcommn.c (otv_ClassDef_validate),
	src/otvalid/otvgpos.c (otv_x_sxy): Fix debugging information.


	Get rid of writable static variables (i.e., the string table) in
	afmparse, and fix compilation in FT2_MULTI mode.

	* src/psaux/afmparse.c: Include ft2build.h and FT_FREETYPE_H.
	(AFM_MAX_ARGUMENTS): Define...
	* src/psaux/afmparse.h: Here.
	* src/psaux/Jamfile (_sources): Add afmparse.

	* src/psaux/psconv.c: Include psconv.h.

	* src/type1/t1afm.c: Don't include FT_INTERNAL_TYPE1_TYPES_H but
	FT_INTERNAL_POSTSCRIPT_AUX_H.
	* src/type1/t1afm.h: Include FT_INTERNAL_TYPE1_TYPES_H.

2006-01-23  Chia-I Wu  <[e-mail]>

	* include/freetype/freetype.h (FT_Select_Size): Rename the second
	argument from `idx' to `strike_index'.
	(FT_Size_Request_Type): Add FT_SIZE_REQUEST_TYPE_MAX to the end of
	this enum.

	* include/freetype/internal/ftobjs.h (FT_REQUEST_WIDTH,
	FT_REQUEST_HEIGHT): New macros to get the width and height of a
	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.
	(FT_Match_Size): Round before matching.  This was what we did and it
	does cause some problems without rounding.

	* src/cff/cffobjs.c (cff_size_select), src/truetype/ttdriver.c
	(tt_size_select): Set the font metrics.
	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.

	* src/cff/cffobjs.c (cff_size_request), src/truetype/ttdriver.c
	(tt_size_request): Set the font metrics.
	Call cff_size_select/tt_size_select when some strike is matched.

	* src/bdf/bdfdrivr.c, src/cff/cffobjs.c, src/cid/cidobjs.c,
	src/pcf/pcfdrivr.c, src/truetype/ttdriver.c, src/type1/t1objs.c,
	src/type1/t1objs.h, src/type42/t42objs.c, src/winfonts/winfnt.c:
	Set the font metrics.
	s/index/strike_index/.

	* src/tools/test_afm.c, src/psaux/psconv.c: Older versions of these
	files were committed.  Just a catch-up.
	(PS_Conv_ToFixed): Remove the `goto'.
	(PS_Conv_ASCIIHexDecode, PS_Conv_EexecDecode): Speed up a little.

	* src/sfnt/ttsbit.c (tt_face_load_sbit_strikes,
	tt_face_load_strike_metrics), src/sfnt/ttsbit0.c
	(tt_face_load_sbit_strikes, tt_face_load_strike_metrics): The
	advertised metrics in `available_sizes' are different from those
	actually used.

2006-01-23  Chia-I Wu  <[e-mail]>

	* src/psaux/psaux.c src/psaux/psauxmod.c src/type1/t1driver.c: Make
	AFM parser optional, controlled by `T1_CONFIG_OPTION_NO_AFM'.

2006-01-22  Werner Lemberg  <[e-mail]>

	* builds/unix/install-sh, builds/unix/mkinstalldirs: Updated from
	`texinfo' CVS module at savannah.gnu.org.

2006-01-21  Werner Lemberg  <[e-mail]>

	* src/autofit/rules.mk (AUTOF_DRV_SRC): Add afwarp.c.

	* src/autofit/afloader.c (af_loader_load_g): Move AF_USE_WARPER up
	to avoid compiler warnings.

	* src/autofit/afwarp.c (af_warper_compute_line_best): Remove
	shadowing variable declarations.
	Fix warning parameters and replace printf with AF_LOG.
	(af_warper_compute): Remove unused variable.

2006-01-20  David Turner  <[e-mail]>

	Adding experimental implementation of `warp hinting' (new hinting
	algorithm for gray-level and LCD rendering).  It is disabled by
	default, you need to #define AF_USE_WARPER in aftypes.h.

	* src/autofit/afhints.c (af_glyph_hints_scale_dim) [AF_USE_WARPER]:
	New function.
	* src/autofit/afhints.h: Updated.

	* src/autofit/aflatin.c [AF_USE_WARPER]: Include afwarp.h.
	(af_latin_hints_init) [AF_USE_WARPER]: Reset mode to
	FT_RENDER_MODE_NORMAL if an LCD mode is selected.
	(af_latin_hints_apply) [AF_USE_WARPER]: Call af_warper_compute
	appropriately.

	* src/autofit/afloader.c (af_loader_load_g) [!AF_USER_WARPER]:
	Isolate code for adjusting metrics.

	* src/autofit/aftypes.h (AF_USE_WARPER): New macro (commented out by
	default).

	* src/sfnt/ttsbit0.c (tt_face_load_strike_metrics): Fix small bug
	that prevented compilation when FT_OPTIMIZE_MEMORY is defined.

2006-01-19  Brian Weed  <[e-mail]>

	* builds/win32/visualc/freetype.dsp: Updated.

2006-01-17  Werner Lemberg  <[e-mail]>

	Use pscmap service in CFF module.

	* src/cff/cffcmap.c (cff_cmap_uni_pair_compare): Removed.
	(cff_sid_to_glyph_name): New function.
	(cff_cmap_unicode_init, cff_cmap_unicode_done,
	cff_cmap_unicode_char_index, cff_cmap_unicode_char next): Use pscmap
	service.
	(cff_cmap_unicode_class_rec): Updated.
	* src/cff/cffcmap.h (CFF_CMapUnicode, CFF_CMap_UniPair): Removed.


	* src/psnames/psmodule.c (ps_unicodes_char_next): Fix `unicode'
	return value.
