[cache] Fix Savannah bug #31923, patch drafted by Harsha.
When a node comparator changes the cached nodes during the
search of a node matching with queried properties, the
pointers obtained before the functon should be updated to
prevent the dereference to freed or reallocated nodes.
To minimize the rescan of the linked list, the update is
executed when the comparator notifies the change of cached
nodes. This change depends previous change:
38b272ffbbdaae276d636aec4ef84af407d16181
* src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Rescan the
top node if the cached nodes are changed.
* src/cache/ftccache.c (FTC_Cache_Lookup): Ditto.

|
2011-01-09T22:49:07
|
|
[cache] Notice if a cache query induced the node list change.
Some node comparators (comparing the cache node content and
the properties specified by the query) can flush the cache
node to prevent the cache inflation. The change may
invalidate the pointers to the node obtained before the node
comparison, so the change should be noticed to the caller.
The problem caused by the cache node changing is reported by
Harsha, see Savannah bug #31923.
* src/cache/ftccache.h (FTC_Node_CompareFunc): Add new
argument `FT_Bool* list_changed' to indicate the change of
the cached nodes to the caller.
(FTC_CACHE_LOOKUP_CMP): Watch the change of the cached nodes
by `_list_changed'.
(FTC_CACHE_TRYLOOP_END): Take new macro argument `_list_changed'
and update it when FTC_Manager_FlushN() flushes any nodes.
* src/cache/ftccback.h (ftc_snode_compare): Updated to fit
with new FTC_Node_CompareFunc type. (ftc_gnode_compare): Ditto.
* src/cache/ftcbasic.c: Include FT_INTERNAL_OBJECTS_H to
use TRUE/FALSE macros. (ftc_basic_gnode_compare_faceid):
New argument `FT_Bool* list_changed' to indicate the change
of the cache nodes, anyway, it is always FALSE.
* src/cache/ftccmap.c: Include FT_INTERNAL_OBJECTS_H to
use TRUE/FALSE macros. (ftc_cmap_node_compare):
New argument `FT_Bool* list_changed' to indicate the change
of the cache nodes, anyway, it is always FALSE.
(ftc_cmap_node_remove_faceid): Ditto.
* src/cache/ftccache.c (FTC_Cache_NewNode): Pass a NULL
pointer to FTC_CACHE_TRYLOOP_END(), because the result is
not needed. (FTC_Cache_Lookup): Watch the change of the cache
nodes by `list_changed'. (FTC_Cache_RemoveFaceID): Ditto.
* src/cache/ftcglyph.c: Include FT_INTERNAL_OBJECTS_H to
use TRUE/FALSE macros. (ftc_gnode_compare): New argument
`FT_Bool* list_changed' to indicate the change of the cache
nodes, anyway, it is always FALSE. (FTC_GNode_Compare):
New argument `FT_Bool* list_changed' to be passed to
ftc_gnode_compare().
* src/cache/ftcglyph.h (FTC_GNode_Compare): Ditto.
* src/cache/ftcsbits.c (ftc_snode_compare): New argument
`FT_Bool* list_changed' to indicate the change of the cache
nodes, anyway. It is updated by FTC_CACHE_TRYLOOP().
(FTC_SNode_Compare): New argument `FT_Bool* list_changed'
to be passed to ftc_snode_compare().
* src/cache/ftcsbits.h (FTC_SNode_Compare): Ditto.

[cache] Deduplicate the code to get the top node by a hash.
There are several duplicated codes getting the top node
from a cache by a given hash, like:
idx = hash & cache->mask;
if ( idx < cache->p )
idx = hash & ( cache->mask * 2 + 1 );
pnode = cache->buckets + idx;
To deduplicate them, a cpp-macro to do same work
FTC_NODE__TOP_FOR_HASH( cache, hash ) is introduced.
For non-inlined config, non-ftc_get_top_node_for_hash() is
also introduced.
* src/cache/ftccache.h (FTC_NODE__TOP_FOR_HASH): Declare
and implement inlined version.
(FTC_CACHE_LOOKUP_CMP): Use FTC_NODE__TOP_FOR_HASH().
* src/cache/ftccache.c (ftc_get_top_node_for_hash): Non-

ftc_gnode_compare() for inlined FTC_CACHE_LOOKUP_CMP()
(see `nodecmp' argument). Under non-inlined config,
ftc_gnode_compare() is invoked by FTC_Cache_Lookup(),
via FTC_Cache->clazz.node_compare().
* src/cache/ftcglyph.h (FTC_GNode_Compare): Ditto.
* src/cache/ftcsbits.c (FTC_SNode_Compare): Ditto,
for ftc_snode_compare().

Apply Savannah patch #7422.
If we encouter a space in a string then the sbit buffer is NULL,
height and width are 0s. So the check in ftc_snode_compare will
always pass for spaces (comparision with 255). Here the comments
above the condition are proper but the implementation is not. When
we create an snode I think it is the proper way to initialize the
width to 255 and then put a check for being equal to 255 in snode
compare function.
* src/cache/ftcsbits.c (FTC_SNode_New): Initialize sbit widths with
value 255.

[cache] Change the hash types to FT_PtrDist.
On LLP64 platforms (e.g. Win64), FT_ULong (32-bit)
variables are inappropriate to calculate hash values
from the memory address (64-bit). The hash variables
are extended from FT_ULong to FT_PtrDist and new
hashing macro functions are introduced. The hash
values on 16-bit memory platforms are changed, but
ILP32 and LP64 are not changed. The hash value in
the cache subsystem is not reverted to the memory
address, so using signed type FT_PtrDist is safe.
* src/cache/ftccache.h (_FTC_FACE_ID_HASH): New hash
function to replace FTC_FACE_ID_HASH() for portability.
* src/cache/ftcmanag.h (FTC_SCALER_HASH): Replace

Change the type of FT_MEM_VAL() from FT_ULong to FT_PtrDist.
On LLP64 platforms (e.g. Win64), unsigned long (32-bit)

type FT_PtrDist is safe.

[raccess] Skip unrequired resource access rules by Darwin VFS.
When a resource fork access rule by Darwin VFS could open the
resource fork but no font is found in it, the rest of rules
by Darwin VFS are skipped. It reduces the warnings of the
deprecated resource fork access method by recent Darwin kernel.
Fix MacPorts ticket #18859:
http://trac.macports.org/ticket/18859
* src/base/ftobjs.c (load_face_in_embedded_rfork):
When FT_Stream_New() returns FT_Err_Cannot_Open_Stream, it
means that the file is possible to be fopen()-ed but zero-sized.
Also there is a case that the resource fork is not zero-sized,
but no supported font exists in it. If a rule by Darwin VFS
falls into such cases, there is no need to try other Darwin VFS
rules anymore. Such cases are marked by vfs_rfork_has_no_font.
If it is TRUE, the Darwin VFS rules are skipped.

[raccess] Grouping resource access rules based on Darwin VFS.
MacOS X/Darwin kernel supports a few tricky methods to access
a resource fork via ANSI C or POSIX interface. Current resource
fork accessor tries all possible methods to support all kernels.
But if a method could open a resource fork but no font is found,
there is no need to try other methods older than tested method.
To determine whether the rule index is for Darwin VFS, a local
function ftrfork.c::raccess_rule_by_darwin_vfs() is introduced.
To use this function in ftobjs.c etc but it should be inlined,
it is exposed by ftbase.h.
* src/base/ftrfork.c (FT_RFork_Rule): New enum type to identify
the rules to access the resource fork.
(raccess_guess_rec): New structure to bind the rule function and
rule enum type.
(FT_Raccess_Guess): The list of the rule functions is replaced by
(raccess_guess_table): This. This is exposed to be used by other
intra module functions.
(raccess_rule_by_darwin_vfs): A function to return a boolean
if the rule specified by the rule index is based on Darwin VFS.

Prevent to open a FT_Stream for zero-sized file on non-Unix.
builds/unix/ftsystem.c prevents to open an useless stream from
zero-sized file and returns FT_Err_Cannot_Open_Stream, but the
stream drivers for ANSI C, Amiga and VMS return useless streams.
For cross-platform consistency, all stream drivers should act
same.
* src/base/ftsystem.c (FT_Stream_Open): If the size of the opened
file is zero, FT_Err_Cannot_Open_Stream is returned.
