Alexei Podtelezhnikov e1a4e081aa [cache] Merge functions.
* src/cache/ftccache.c (FTC_Cache_Init): Merge into...
(ftc_cache_done): ... this function, with unnecessary checks removed.
2023-05-12 22:27:08 -04:00
Alexei Podtelezhnikov 771ff8bd03 [cache] Minor casting and cosmetic updates.
* src/cache/ftcglyph.c (ftc_gcache_{init,done}): Remove casting.
(FTC_GCache_Lookup): Cosmetic variable renaming.

Alexei Podtelezhnikov ad708d70c9 [cache] Revise the dynamic hash table accounting.
Instead of counting entries relative to the middle of the hash table,
this switches to the absolute counter with the full index range mask.
As a result, some calculations become a bit simpler.  The cache resizing
logic stays largely the same.

* src/cache/ftccache.h (FTC_NODE_TOP_FOR_HASH): Revised with new counter.
* src/cache/ftccache.c (ftc_get_top_node_for_hash): Ditto.
(ftc_cache_resize): Simplify reallocations and stop their zeroing.
(ftc_cache_init): Stop over-allocating but keep zeroing initially.
(FTC_Cache_Clear, FTC_Cache_RemoveFaceID): Updated accordingly.

Werner Lemberg d52166ae9d [cache] Signature fixes.
* src/cache/ftcglyph.c, src/cache/ftcglyph.h (FTC_GNode_Compare): Remove
redundant function.  It is equivalent to `ftc_gnode_compare` and becomes
completely meaningless with fixed signatures.
Update all callers.

* src/cache/ftcsbits.c, src/cache/ftcsbits.h (FTC_SNode_Compare): Remove
redundant function.  It is equivalent to `ftc_snode_compare` and becomes
completely meaningless with fixed signatures.
Update all callers.

Alexei Podtelezhnikov f2f9754542 [cache] Revise list cleansing.
* src/cache/ftcmru.c (FTC_MruList_RemoveSelection): Use one loop to
do it.
* src/cache/ftcmanag.c (FTC_Manager_Compress, FTC_Manager_FlushN):
Streamline loops.

Alexei Podtelezhnikov 8faf57dd17 * src/cache/ftccmap.c (FTC_CMapCache_Lookup): Avoid `FT_Set_Charmap`.
Set charmap aggressively without all validations of `FT_Set_Charmap`
because we take it from the available array and only temporarily.
Even CMap Format 14 will gracefully return 0.

David Turner 0f35b042e0 [build] Really fix multi and C++ builds.
The following builds were still failing due to previous changes:

  make multi
  make multi CC="c++"
  make CC="c++"

This patch fixes the issues, which were missing includes to get the
right macro definitions in multi-build mode.

Also, `FT_UNUSED' is actually used by third-party code, so move it
back to `public-macros.h' to avoid breaking it.

* include/freetype/config/public-macros.h (FT_EXPORT): Remove
special definition for C++.
(FT_UNUSED): Define here instead of...
* include/freetype/config/compiler-macros.h: ... here.
(FT_FUNCTION_DECLARATION): Remove special definition for C++.
(FT_LOCAL_ARRAY_DEF): Fix definition.

* src/cache/ftccback.h, src/lzw/ftzopen.h, src/gxvalid/gxvmort.h,
src/gxvalid/gxvmorx.h: Add `FT_BEGIN_HEADER' and `FT_END_HEADER'.

David Turner e13391333f Make macros for header file names optional.
We no longer have to take care of the 8.3 file name limit; this
allows us (a) to introduce longer, meaningful file names, and (b) to
avoid macro names in `#include' lines altogether since some
compilers (most notably Visual C++) doesn't support this properly.

*/*: Replace

   #include FOO_H

with

   #include <freetype/foo.h>

or something similar.  Also update the documentation.
