||
[base] 'close' callback may not use `stream->memory`.
|
||
|
||
The documentation for `FT_StreamRec::memory` states that it 'shouldn't be
|
||
touched by stream implementations'. This is true even for internal
|
||
implementations of the 'close' callback, since it is not guaranteed that
|
||
`memory` will even be set when the 'close' callback occurs.
|
||
|
||
* src/base/ftobjs.c (new_memory_stream): stash current `memory` in
|
||
`stream->descriptor`.
|
||
(memory_stream_close): Use it.
|
||
|
||
2023-01-17 Ben Wagner <bungeman@chromium.org>
|
||
|
||
[base] Always close user-provided stream.
|
||
|
||
The `FT_Open_Face` documentation states
|
||
|
||
> If `FT_OPEN_STREAM` is set in `args->flags`, the stream in `args->stream`
|
||
> is automatically closed before this function returns any error (including
|
||
> `FT_Err_Invalid_Argument`).
|
||
|
||
However, if the user provides a stream in `args.stream` with
|
||
`FT_OPEN_STREAM` set and a `close` function, but then for some reason passes
|
||
NULL for `aface` and a non-negative `face_index`, the error
|
||
`Invalid_Argument` is returned but the `close` callback will not be called
|
||
on the user-provided stream. This may cause resource leaks if the caller is
|
||
depending on the `close` callback to free resources.
|
||
|
||
The difficulty is that a user may fill out a `FT_StreamRec` and pass its
|
||
address as `args.stream`, but the stream isn't really 'live' until
|
||
`FT_Stream_New` is called on it (and `memory` is set). In particular, it
|
||
cannot really be cleaned up properly in `ft_open_face_internal` until the
|
||
stream pointer has been copied into the `stream` local variable.
|
||
|
||
* src/base/ftobj.c (ft_open_face_internal): Ensure that user-provided
|
||
`args.stream.close` is called even with early errors.
|
||
|
||

|
||
|
||
[base] Fix leak of internal stream marked external.
|
||
|
||
`open_face_from_buffer` allocates a new `FT_Stream` to pass to
|
||
`ft_open_face_internal`. Because this is an `FT_OPEN_STREAM`,
|
||
`ft_open_face_internal` will mark this as an 'external stream', which the
|
||
caller must free. However, `open_face_from_buffer` cannot directly free it
|
||
because the stream must last as long as the face. There is currently an
|
||
attempt at this by clearing the 'external stream' bit after
|
||
`open_face_from_buffer` returns successfully. However, this is too late as
|
||
the original stream may have already been closed and the stream on the face
|
||
may not be the same stream as originally passed.
|
||
|
||
It is tempting to use `FT_OPEN_MEMORY` and let `ft_open_face_internal`
|
||
create the stream internally. However, with this method there is no means
|
||
to pass through a 'close' function to the created stream to free the
|
||
underlying data, which must be owned by the stream.
|
||
|
||
A possibility is to check on success if the stream of the face is the same
|
||
as the original stream. If it is then unset the external flag. If not,
|
||
then free the original stream. Unfortunately, while no current
|
||
implementation does so, it is possible that the face still has the original
|
||
stream somewhere other than as the `FT_FaceRec::stream`. The stream needs
|
||
to remain available for the life of the face or until it is closed,
|
||
whichever comes earlier.
|
||
|
||
The approach taken here is to let the stream own itself. When the stream is
|
||
closed it will free itself.
|
||
|
||
* src/base/ftobjs.c (memory_stream_close): Free `stream`.
|
||
(open_face_from_buffer): Simplify error handling, since
|
||
`ft_open_face_internal` always closes `args.stream` on any error.

[truetype] Reset cvt and storage in context load.
|
||
|
||
Currently the cvt and storage are saved and restored in `TT_RunIns`.
|
||
However, this is too granular as the cvt and storage area should be set to
|
||
the original cvt and storage area only when setting up the hinting context.
|
||
This allows for the cvt and storage area to be modified while parsing
|

multiple glyphs, as is the case with composite glyphs.

[truetype] Keep variation store consistent.
|
||
|
||
`tt_var_load_item_variation_store` fills out a `GX_ItemVarStore`. While it
|
||
may return an error, the item store must be left in a consistent state so
|
||
that any use or destruction of the item store can properly use or free the
|
||
data in it. Before this change the counts from the font data were read
|
||
directly into the item store before the actual allocation of the arrays to
|
||
which they referred. There exist many opportunities between the time the
|
||
counts are read and the arrays are allocated to return early due to invalid
|
||
data. When this happened the item store claimed to have entires it actually
|
||
did not, leading to crashes later when it was used.

[base] Report used stream's external status.
|
||
|
||
In `open_face` the initial stream is set on the face, along with the
|
||
information about if FreeType is the owner of the stream object itself. The
|
||
loaders may in the course of their work replace this stream with a new
|
||
stream (as is the case for 'woff' and 'woff2'), which may have a different
|
||
ownership than the initial stream object (likely the original stream object
|
||
is owned by the user and is external, while the new stream object is created
|
||
internally to FreeType and is internal). When the stream is replaced, the
|
||
face's flags are updated with the new ownership status.
|
||
|
||
However, `open_face` cannot itself free this stream as its caller
|
||
`ft_open_face_internal` is responsible for this. In addition, in the case
|
||
of an error `open_face` cannot return an actual face with the new stream and
|
||
its ownership status to the caller. As a result, it must pass this
|
||
information back to the caller as a sort of "failed face" so that the caller
|
||
can clean up.
|
||
|
||
`open_face` was already passing back the new stream but was not passing back
|
||
the stream ownership information. As a result the stream may not have been
|
||
free'd when needed.

[truetype] Restore behavior of ft_var_load_hvvar
|
||
|
||
* src/truetype/ttgcvar.c (ft_var_load_hvvar): restore previous behavior
|
||
|
||
In a previous change [0] the behavior of `ft_var_load_hvvar` was changed
|
||
to not load the item variation store if it was at offset 0, but not
|
||
return an error when this happened. This broke any users, like
|
||
`tt_hvadvance_adjust`, that rely on successful completion of
|
||
`ft_var_load_hvvar` to imply that returned table's `itemStore` had been
|
||
initialized. This lead such users to dereference NULL.
|
||
|
||
This change appears to have been unintentional and unrelated to the
|
||
actual avar2 changes. As a result, fix these NULL dereferences by
|
||
restoring the code to always attempt to initialize the `itemStore`.

[bdf, pfr, psnames] Accelarate charmap searches.
|
||
|
||
The binary searches within charmaps can be accelerated because they
|
||
often contain dense continuous blocks of character codes. Within such
|
||
blocks, you can predict matches based on misses. This method has been
|
||
deployed in `bdf` since 0f122fef34; we only refactor it there. We now
|
||
use it in `pfr` and `psnames`, which speeds up the unicode charmap
|
||
access by about 50% in PFR and Type 1 fonts.

||
|
||
* src/bdf/bdfdrivr.c (bdf_cmap_char_{index,next}): Refactor.

|
||
https://github.com/harfbuzz/boring-expansion-spec/blob/main/avar2.md
|
||
|
||
for the specification.
|
||
|
||
Currently, this is implemented only in most recent OS versions on Apple

platforms and in the HarfBuzz library, but it is expected to be added to the
|
||
OpenType standard soon.

[pfr] Fortify the kerning code.
|
||
|
||
Any array index must be strictly less then the array size. Therefore,
|
||
we must reject indexes that are equal to the array size. Alternatively,
|
||
we should move the bounds check before the index decrement but that
|
||
would be confusing.
|
||
|
||
In addition, it is ok to decrement zero (.notdef) and get UINT_MAX,
|
||
which is then automatically rejected in the bounds check.

[base] Build outlines in amortized constant time.
|
||
|
||
When resizing the loader's points and contours, resize them to at least 1.5
|
||
times their current size. The code currently only reserves as much space as
|
||
is currently required, leading to O(n^2) runtime when adding points one at a
|
||
time.
|
||
|
||
This change does not attempt to ever shrink the loader's point and contour
|
||
storage since this was not attempted previously either. The 1.5 multiple
|

was chosen as a trade-off between potentially unused space and the runtime.

doc: Clarify description of `FT_Stream_IoFunc`.
|
||
|
||
The existing documentation comments on `FT_Stream_IoFunc` hinted at the dual
|
||
seek/read behavior required for custom stream implementations to work, but
|
||
it didn't explicitly explain it. Without looking at the internals of
|
||
FreeType, it was easy for someone to assume their implementation should
|
||
handle both seek and read operations all the time. If this is done, you get
|
||
a variety of errors, but mostly just `Unknown_File_Format` (error code
|
||
0x02).

[base] Improve error handling in `FT_GlyphLoader_CheckPoints`.
|
||
|
||
If `FT_GlyphLoader_CreateExtra` returns an error (and a couple of other
|
||
places), `FT_GlyphLoader_CheckPoints` would propagate the error immediately,

rather than cleaning up the partially set up `FT_GlyphLoader`. As a

consequence, a subsequent attempt to create a glyph could result in a crash.

CMakeLists.txt: Provide both 'freetype' and 'Freetype::Freetype' targets.
|
||
|
||
FreeType can be located by consuming projects that use
|
||
`find_package(Freetype)` either via the old `MODULE` path (which uses
|
||
`FindFreetype.cmake` supplied by CMake), or via the new `CONFIG` path (which
|
||
uses `freetype-config.cmake` as supplied by this project). Up to this point
|
||
the CMake module has supplied the target `Freetype::Freetype` and the config
|
||
file provided by this project the target `freetype`. Now we supply both
|
||
`freetype` and `Freetype::Freetype` so that consuming projects can always
|
||
use the target `Freetype::Freetype` regardless of what path was taken by
|
||
`find_package(Freetype)`.

[stream] Fix reading s32 when long is s64
|
||
|
||
`FT_READ_LONG`, `FT_GET_LONG`, and related macros did not return
|
||
negative values when `long` is more than 32 bits. `FT_Stream_ReadULong`
|
||
would read four bytes into the LSB of an `FT_ULong` and return that.
|
||
Since this can never set the MSb of the `FT_ULong` when `FT_ULong` is
|
||
more than 32 bits the cast to `FT_Long` never resulted in a negative
|
||
value.
|
||
|
||
Fix this by modifying `FT_Stream_Read*` to return a type of the same
|
||
size as the bytes it is reading and changing the `FT_READ_*` and
|
||
`FT_GET_*` macros to cast to the same type returned by `FT_Stream_Read*`
|
||
but with the correctly signed type (instead of casting to what is
|
||
assumed to be the type of `var` which will happen automatically anyway).
|
||
|
||
There exist a few cases like with the `OFF3` variants where there isn't
|
||
generally a type with the correct size. `FT_PEEK_OFF3` works around this
|
||
loading the bytes into the three most significant bits and then doing a
|
||
signed shift down. `FT_NEXT_OFF3` also already worked correctly by
|
||
casting this signed value to another signed type. `FT_Stream_GetUOffset`
|
||
works correctly but one must be careful not to attempt to cast the
|
||
returned value to a signed type. Fortunately there is only
|
||
`FT_GET_UOFF3` and no `FT_GET_OFF3`.
|
||
|
||
All of these cases are handled correctly when reading values through
|
||
`FT_Stream_ReadFields` since it generically computes the signed value
|
||
through an `FT_Int32`. This change is essentially doing the same for
|
||
these macros.

||
|
||
* include/freetype/internal/ftstream.h (FT_NEXT_*, FT_GET_*, FT_READ*):

[type1] Directly search for eexec in private dict
|
||
|
||
This code originally just searched for `eexec`. This was later modified
|
||
to check that the `eexec` found is valid (not in a string or comment).
|
||
This was done by searching for `eexec` as before and then, for each
|
||
`eexec` found, searching from the beginning using the correct parsing to
|
||
see if the `eexec` was still found. If the private dictionary is large
|
||
and contains many copies of `eexec` which are not valid, the initial
|
||
part of the private dictionary is scanned once for each, potentially
|
||
leading to n^2 parsing time.
|
||
|
||
Instead of finding an initial `eexec` and then re-parsing to discover if
|
||
it is valid, drop the initial search for `eexec` and just parse to find
|
||
a valid `eexec`. This is strictly faster since the validation must
|
||
happen anyway and avoids restarting from the beginning each time an
|
||
`eexec` is found in the data.
|
||
|
||
* src/type1/t1parse.c (T1_Get_Private_Dict): avoid n^2 parsing

[gzip] Handle inflate returning Z_NEED_DICT
|
||
|
||
When `inflate` returns `Z_NEED_DICT` this is currently not reported as
|
||
an error and callers may assume that the decompression succeeded when it
|
||
did not. In particular, a compressed table in a woff file may not
|
||
actually be decompressed and written as expected, leaving the backing
|
||
memory for the expanded table uninitialized.
|
||

||
* src/gzlip/ftgzip.c (FT_Gzip_Uncompress): treat `Z_NEED_DICT` as

compressed and other uncompressed. After loading the first compressed

document the ownership flag on the glyph slot was set to true but never

set to false. As a result after loading a compressed document a glyph

from an uncompressed document would load fine, but when this glyph slot

was cleared it would try to free its document resulting in a wild free.

[meson] Remove `default_library=both` from `default_options`.
|
||
|
||
It is inconsistent with what all other Meson projects do.
|
||
|
||
It also prevents static linking to FreeType when it is a subproject because
|
||
`default_options` in a subproject takes precedence on values set on the main
|
||
project. For example, building 'GStreamer' with `-Ddefault_library=static`
|
||
would still dynamically link on FreeType unless the user also sets
|
||
`-Dfreetype2:default_library=static`.
|
||
|
||
* meson.build: Updated.
|
||
|
||
* .gitlab-ci.yml: Retain `both` option for testing.

[sfnt] Fix bounds check in SVG.
|

||
The `SVG_DOCUMENT_LIST_MINIMUM_SIZE` macro is non trivial and not

protected by parentheses. As a result, the expression
|
||
`table_size - SVG_DOCUMENT_LIST_MINIMUM_SIZE` expands to
|
||
`table_size - 2U + SVG_DOCUMENT_RECORD_SIZE` instead of the expected
|
||
`table_size - (2U + SVG_DOCUMENT_RECORD_SIZE)`. This causes an incorrect
|
||
bounds check which may lead to reading past the end of the `SVG ` table.

[psaux] Full bounds check for OtherSubr 19.
|
||
|
||
It is possible for OtherSubr 19 to be invoked when `decoder->buildchar` is
|
||
NULL (so that `decoder->len_buildchar` is 0), the `blend` is non-NULL with
|
||
`blend->num_designs` set to 2, and the user supplied `idx` to be large (for
|
||
example 0xFFFFFFFE). Since these are all `FT_UInt32` the existing bounds
|
||
check overflows in a well defined manner, allowing for an invalid call to
|
||
`memcpy`.
|
||
|
||
In addition, it is possible to call OtherSubr 19 with
|
||
`decoder->len_buildchar`, `blend->num_designs`, and `idx` all zero (implying
|
||
that `blend->weight_vector` and `decoder->buildchar` are NULL). This passes
|
||
the bounds check (it is logically always fine to copy nothing starting at
|
||
index zero) but may invoke undefined behavior in `ft_memcpy` if it is backed
|
||
by `memcpy`. Calling `memcpy` with either the `src` or `dst` NULL is
|
||
undefined behavior (even if `count` is zero).
|
||
|
||
* src/psaux/psintrp.c (cf2_interpT2CharString): Correctly check that
|
||
`blend->num_designs` can be copied to `decoder->buildchar[idx]`.
|
||
Also avoid passing NULL to `ft_memcpy`.

[psaux] Revise `PS_Table` handling.

stroke such an outline. Clarify the existing documentation on this

how they will be reported), why they might arise, and better explain in

what cases they may be an issue.

[base] Undefined scale means no scale.
|

|

It might be surprising that FreeType does not have default ppem and

the size has to be set explicitly or face undefined behavior with

undefined variables and errors. This offers an alternative to

missing or zero scale by simply setting FT_LOAD_NO_SCALE. Defined

behavior is bettr than undefined one.

Revert "[bzip2] Avoid use of uninitialized memory."
|
||
|
||
This reverts commit d276bcb7f0c02c20d3585b2e5626702df6d140a6.
|
||
|
||
The original commit did avoid the use of uninitialized memory. However,
|
||
it appears that the original commit is no longer required. The
|
||
underlying issue was resolved by a change in freetype2-testing "Build
|
||
bzip2 correctly." [0]. Prior to [0] bzip2 was built without msan, so
|
||
bzip2 writes were not tracked or considered initialized. Clearing
|
||
`buffer` in the original commit allowed msan to see the `buffer` content
|
||
initialized once in FreeType code, but msan saw no writes into buffer
|
||
from bzip2. With bzip2 now built with msan, the bzip2 writes are
|
||
properly instrumented and msan sees the bzip2 writes into the buffer. As
|
||
a result the original commit can be safely reverted to allow for better
|
||
detection of other uninitialized data scenarios.

[type42] Track how much type42 ttf data is available.
|
||
|
||
Currently `T42_Open_Face` eagerly allocates 12 bytes for the ttf header
|
||
data which it expects `t42_parse_sfnts` to fill out from /sfnts data.
|
||
However, there is no guarantee that `t42_parse_sfnts` will actually be
|
||
called while parsing the type42 data as the /sfnts array may be missing
|
||
or very short. This is also confusing behavior as it means
|
||
`T42_Open_Face` is tightly coupled to the implementation of the very
|
||
distant `t42_parse_sfnts` code which requires at least 12 bytes to
|
||
already be reserved in `face->ttf_data`.
|
||
|
||
`t42_parse_sfnts` itself eagerly updates `face->ttf_size` to track how
|
||
much space is reserved for ttf data instead of traking how much data has
|
||
actually been written into `face->ttf_data`. It will also act strangely
|
||
in the presense of multiple /sfnts arrays.
|
||
|
||
* src/type42/t42objs.c (T42_Open_Face): ensure `ttf_data` is initialized
|
||
to NULL. Free `ttf_data` on error.
|
||
|
||
* src/type42/t42parse.c (t42_parse_sfnts): delay setting `ttf_size` and
|
||
set it to the actual number of bytes read. Ensure `ttf_data` is freed
|
||
if there are multiple /sfnts arrays or there are any errors.

* meson.build: Optimize lookup for `python3` program.
|
||
|
||
The python module's `find_installation` method is intended to provide
|
||
routines for compiling and installing python modules into the
|
||
`site-packages` directory. It does a couple of slow things, including run
|
||
an introspection command to scrape sysconfig info from the detected
|
||
interpreter, which are not needed for the sole use case of invoking the
|
||
found installation as an executable.
|
||
|
||
Furthermore, when invoked without the name or path of a python binary, it is
|
||
hardcoded to always look for `python3` corresponding to the interpreter
|
||
meson itself uses to run. So using `find_installation` did not even allow
|
||
detecting `python2` as a fallback.
|
||
|
||
Instead, switch to a simple `find_program` lookup that finishes as soon as
|
||
the program is found.

* builds/meson/*.py: Fix name of python executable for auxiliary scripts.
|
||
|
||
The previous change to check the return code of `run_command` invocations
|
||
caused the CI to fail. Although most scripts used `python_exe` as the
|
||
program command, the script to determine the project version did not.
|
||
|
||
But, all scripts used `python` as the shebang, and this is not available on
|
||
all systems. Particularly Debian does not provide a `python` command,
|
||
though `python3` does exist. This meant that formerly the version number
|
||
was lacking, and now the build simply fails.
|
||
|
||
Instead, rely on `python3` since it is guaranteed to exist when running
|
||
meson, and `python2` is end of life anyway.
|
||
|
||
2021-12-17 Eli Schwartz <eschwartz@archlinux.org>
|
||
|
||
* meson.build: Check the return value of `run_command`.
|
||
|
||
By default, errors are not checked and a command that is somehow broken will
|
||
just capture incorrect output (likely an empty string). Current development
|
||
versions of meson now raise a warning for this implicit behavior, and advise
|
||
explicitly setting the `check:` keyword argumend to determine whether a
|
||
failing return code should be considered an error.
|
||
|
||
Since none of the commands in this project are expected to fail, mark them
|
||
as required to succeed.

[truetype] Honor FT_LOAD_ADVANCE_ONLY if `hdmx` is usable.
|
||
|
||
This simply shortcuts the glyph loading if FT_LOAD_ADVANCE_ONLY
|
||
is specified by FT_Get_Advances and the `hdmx` data are located.
|
||
Particularly, the classic v35 interpreter or "verified" ClearType
|
||
fonts might see 100x speed up in retrieving the hdmx cache.

[truetype] Relocate subpixel flag setting.
|
||
|
||
`TT_RunIns` is too busy to deal with subpixel flags. It is better
|
||
to set them in `tt_loader_init`, which is executed before each
|
||
glyph program.
|
||
|
||
* src/truetype/ttinterp.c (TT_RunIns): Move the flag setting from

This also fixes an Infinality buglet. The `ignore_x_mode` should be

[bdf] Fix use of uninitialized value.
|
||
|
||
In _bdf_readstream if the data contained no newline then the buffer
|
||
would continue to grow and uninitialized data read until either the
|
||
uninitialized data contained a newline or the buffer reached its
|
||
maxiumum size. The assumption was that the line was always too long and
|
||
the buffer had been filled, however this case can also happen when there
|
||
is not enough data to fill the buffer.
|
||
|
||
Correct this by properly setting the cursor to the end of the available
|
||
data, which may be different from the end of the buffer. This may still
|
||
result in one extra allocation, but only on malformed fonts.
|
||
|
||
* src/bdf/bdflib.c (_bfd_readstream): Correctly update cursor. Remove
|

[truetype] Quietly reject out-of-spec `hdmx` tables.
|
||
|
||
The `hdmx` table is optional and can be safely rejected without

must be equal to the number of glyphs + 2 + 32-bit padding.

Provide C++ versions for public macros with casts.
|

|
||
Many FreeType clients use C++. However `g++ -Wold-style-cast` warns for
|
||
macros with C-style casts even for system header files; this also affects
|
||
directories included with `-isystem`. While this could be seen as a problem
|
||
with g++, the problem is more a philosophical one: Over the time, C and C++

diverged more and more, and some features of C are no longer the 'right'

solution in C++.

[mm] Tolerate missing Blend dictionary entries
|
||
|
||
In a Multiple Master font, the Blend dictionary must contain valid
|
||
Private, FontInfo, and FontBBox. The current code will error if any of
|
||
these are present and invalid, but will not error and will provide
|
||
uninitialized data if the Blend dictionary exists but does not contain
|
||
one of these entries. This change reverts to the older behavior of
|
||
treating any missing entries as containing all zero data and not
|
||
returning an error.
|
||
|

In the future it may be best to keep track of when these are actually

initialized and error if they are not.

[mm] Delay setting blend weight and design position.
|
||
|
||
Previously the `blend->weight_vector`, `blend->default_weight_vector`,
|
||
and `blend->design_pos` were set early to allocated but uninitialized
|
||
memory under the assumption that the memory would eventually be
|
||
initialized. However, it is possible that some of the required
|
||
keywords may not actually be present, leaving the memory uninitialized.
|
||
This is different from a present but invalid table, which would produce
|
||
an error.

[sfnt] Delay setting gasp ranges and count until computed.
|

Previously, the gasp.numRanges was set and gasp.gaspRanges was

|
||
not be entered. It is also possible that the gaspRanges allocation
|
||
could fail but the numRanges still be set to non-zero. In such cases

autogen.sh: Only copy submodules if building from a git branch.
|
||
|
||
`autogen.sh` fails if building from a standard source tarball. Firstly, git
|
||
expects to be called in a git repository, then `copy_submodule_files`
|
||
blindly attempts to copy files.
|
||
|
||
Debian, Ubuntu, Linux Mint, and other derivatives all run `autogen.sh`
|
||
before compiling to regenerate build files.
|
||
|
||
This patch ensures that various git commands are only called and 'dlg' files
|

are only copied if `autogen.sh` is called from a git repository.

2021-10-01 Alexei Podtelezhnikov <apodtele@gmail.com>
|

Additional `FT_MSB` macro definitions.

[builds/unix] Do not use autoconf SIZEOF.
|
||
|
||
* builds/unix/ftconfig.h.in [FT_USE_AUTOCONF_SIZEOF_TYPES]: Removed.
|
||
* builds/unix/configure.raw: Remove AC_CHECK_SIZEOF and update.
|
||
|
||
After this commit, autoconf builds will fully rely on <limits.h>
|
||
rather than falling back on it if AC_CHECK_SIZEOF failed for some
|
||
reason. There is a risk that misconfigured cross-compilation might
|
||
have wrong headers. Note that Meson and CMake builds always relied on
|
||
<limits.h> for sizes and availability of integer types.

Propagate sign when reading OFF3.
|
||
|
||
Signed 24-bit values are extremely rare. FreeType only reads them in
|
||
PFR fonts with bitmap strikes conditionally. They have not been seen
|
||
in the known fonts. That is why this bug could never be discovered.
|
||
`FT_FRAME_OFF3` propagates sign correctly.
|
||
|
||
* include/freetype/internal/ftstream.h (FT_PEEK_OFF3, FT_PEEK_OFF3_LE):

BDF comments are neither actually collected nor retrieved. There is

* src/bdf/bdflib.c (_add_bdf_comment): Delimit comments with zeros...

[base] Initialize stream memory earlier.
|
||
|
||
With Windows memory management tracking heap, it is important to use
|

it during the stream opening fallback. In Unix, the argument is
|
||
unused, but it is better to set it correctly.
|
||
|
||
* src/base/ftobjs.c (FT_Stream_New): Set memory before calling

[builds/windows] Revert back to `CreateFileA` only.
|
||
|
||
Calling `CreateFileW` without making sure that the patname is really
|
||
`wchar_t` is a bad idea and can lead to unpredictable overreads. For
|
||
Windows CE, we impelemnt the missing API.
|

Fixes #1098 and !76 again.
|
||
|

[builds/windows] Try both wide and narrow `CreateFile`
|
||
|
||
Windows handles wchar_t* UTF-16 and char* ANSI (presently UTF-8)
|
||
filenames using alternative -A and -W API. We'll try them both
|
||
when opening a file. This means that you should not worry about
|

about conversions.
|
||
|
||
Fixes #1098 and !76.

the overall performance. The loss of precision is tolerable until the

divisors (the components dx and dy) approach 32 - PIXEL_BITS. With

PIXEL_BITS = 8, this corresponds to 65,000 pixels or the bitmap size

that we refuse to render anyway.

[truetype] Simplify `trick_names'.
|
||
|
||
* src/truetype/ttobjs.c (tt_check_trickyness_family): For the case
|
||
that the beginning part of a long tricky family name is already
|
||
registered as another tricky family name, no need to double-check
|
||
the longer one. Such long tricky family names are removed from
|
||
the `trick_names'.

[truetype] New function to skip the randomization tag.
|
||
|
||
* src/truetype/ttobjs.c (tt_skip_pdffont_random_tag):
|
||
New function to skip the randomization tag in the names of the
|
||
fonts embedded in a PDF. It is used by tt_check_trickyness_family(),
|
||
to keep from mistaking "DLC" in the randomization tag as a
|
||
tricky font name. See discussion in:

This commit synchronizes zlib support with both autotools and cmake: If no

external zlib is found (or intentionally disabled on the command line), use
|

the internal zlib by undefining `FT_CONFIG_OPTION_SYSTEM_ZLIB` without
|

|

|
||
Fix invalid memory access in `bsdf` rasterizer.
|
||
|
||
Do not generate SDF from bitmap if the `FT_GLYPH_OWN_BITMAP` flag is not
|
||
set. In some cases the bitmap buffer is freed but still points to a valid
|
||
address; to handle those cases check the flag before accessing the memory.
|
||
|
||
* src/sdf/ftsdfrend.c (ft_bsdf_render): Handle the above case.
|
||
Also, return an error message if the bitmap's rows/pitch is invalid,
|
||
otherwise `slot->buffer` might be assigned to some invalid memory location.
|
||
(ft_sdf_render): Same as above.
|
||
Plus, move the outline back to original state after rasterization and not if
|
||
any error occurs.

[autofit] Split `afwrtsys.h`.
|
||
|
||
The header file `afwrtsys.h` has two distinct functions: to include the
|
||
required writing system headers and also to generate code for each writing
|
||
system. At each current use site only one or the other is used, with
|
||
various macro trickery selecting one or the other. Split this header into
|
||
`afws-decl.h` for the required writing system declarations and `afws-iter.h`
|
||
for iterating over the writing systems to generate code.
|
||
|
||
The motivation for this change is that the Visual C++ compiler treats the
|
||
standard include guard idiom like `#pragma once` 'if no non-comment code or
|
||
preprocessor directive comes before or after the standard form of the
|
||
idiom'. It appears to check this after macro expansion, so if
|
||
`WRITING_SYSTEM` expands to empty the bottom of `afwrtsys.h` is empty and
|
||
looks like the standard include guard idiom which is treated like `#pragma
|
||
once`, so subsequent inclusion of `afwrtsys.h` is elided.
|
||
|
||
Fixes #1075.
|
||
|
||
* src/autofit/afglobal.c (af_writing_system_classes), src/autofit/aftypes.h
|
||
(AF_WritingSystem), src/autofit/rules.mk (AUTOF_DRV_H): Updated.

* src/autofit/afwrtsys.h: Split into...

* src/autofit/afws-decl.h, src/autofit/afws-iter.h: New files.
