0417e54b | 2022-07-22 16:22:19 | [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. * src/base/ftgloader.c (FT_GlyphLoader_CheckPoints): Implement it. Fixes #1173. | |
 |
1a242558 | 2022-06-30 09:25:14 | [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. * src/base/ftgloadr.c (FT_GlyphLoader_CheckPoints): Ensure all the error conditions exits are consistent, eventually calling `FT_GlyphLoader_Reset`. | |

bec4ef41 | 2022-07-01 12:04:28 | [base] Round values in `FT_MulAdd_Fix`. This avoids regressing Blink layout tests and makes `FT_MulAdd_Fix` delta retrieval implementation consistent with the previous implementation, which used `FT_fixedToInt` and included rounding. * src/base/ftcalc.c (FT_MulAdd_Fix): Implement it. Also fix remaining `temp` initialization compilation issue. Fixes #1169. | |

|
15fef219 | 2022-06-29 11:48:10 | New function `FT_MulAddFix` to compute the sum of fixed-point products. This function, based on the code of `FT_MulFix`, uses 64-bit precision internally for intermediate computations. * include/freetype/internal/ftcalc.h, base/ftcalc.c (FT_MulAddFix): Implement it. | |

f7daf9d2 | 2022-06-17 12:37:02 | [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*): Update macros and return types to use fixed size types for fixed size values. * src/base/ftstream.c (FT_StreamGet*, FT_StreamRead*): Dito.

c26872ed | 2022-05-26 20:27:53 | [svg] Clear correct flags for doc ownership This issue was discovered with an SVG based font with some documents 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. * src/base/ftobjs.c (ft_glyphslot_clear): clear correct flags Fixes: #1162 | |

054782c4 | 2022-01-19 22:14:06 | [base] Undefined scale means no scale.

This offers an alternative to missing or zero scale by simply setting FT_LOAD_NO_SCALE. Defined behavior is bettr than undefined one.

5d27b10f | 2021-07-13 10:59:32 | [base] Fix `FT_Open_Face`'s handling of user-supplied streams. This was already true (though undocumented) most of the time, but not if `FT_NEW` inside `FT_Stream_New` failed or if the `FT_OPEN_XXX` flags were bad. Normally, `FT_Open_Face` calls `FT_Stream_New`, which returns the user-supplied stream unchanged, and in case of any subsequent error in `FT_Open_Face`, the stream is closed via `FT_Stream_Free`. Up to now, however, `FT_Stream_New` allocates a new stream even if it is already given one by the user. If this allocation fails, the user-supplied stream is not returned to `FT_Open_Face` and never closed. Moreover, the user cannot detect this situation: all they see is that `FT_Open_Face` returns `FT_Err_Out_Of_Memory`, but that can also happen after a different allocation fails within the main body of `FT_Open_Face`, when the user's stream has already been closed by `FT_Open_Face`. It is plausible that the user stream's `close` method frees memory allocated for the stream object itself, so the user cannot defensively free it upon `FT_Open_Face` failure lest it ends up doubly freed. All in all, this ends up leaking the memory/resources used by user's stream. Furthermore, `FT_Stream_New` simply returns an error if the `FT_OPEN_XXX` flags are unsupported, which can mean either an invalid combination of flags or a perfectly innocent `FT_OPEN_STREAM` on a FreeType build that lacks stream support. With this patch, the user-supplied stream is closed even in these cases, so the user can be sure that if `FT_Open_Face` failed, the stream is definitely closed. * src/base/ftobjs.c (FT_Stream_New): Don't allocate a buffer unnecessarily. Move error-handling code to make the control flow more obvious. Close user-supplied stream if the flags are unsupported. `FT_Stream_Open` always sets `pathname.pointer`, so remove the redundant (re)assignment. None of the `FT_Stream_Open...` functions uses `stream->memory`, so keep just one assignment at the end, shared among all possible control flow paths. ('Unsupported flags' that may need a stream closure can be either an invalid combination of multiple `FT_OPEN_XXX` mode flags or a clean `FT_OPEN_STREAM` flag on a FreeType build that lacks stream support.) | |
|
a4c8f21a | 2021-07-13 10:44:38 | [base] Reject combinations of incompatible `FT_OPEN_XXX` flags. The three modes are mutually exclusive, and the documentation of the `FT_OPEN_XXX` constants notes this. However, there was no check to validate this in the code, and the documentation on `FT_Open_Args` claimed that the corresponding bits were checked in a well-defined order, implying it was valid (if useless) to specify more than one. Ironically, this documented order did not agree with the actual code, so it could not be relied upon; hopefully, nobody did this and nobody will be hurt by the new validation. Even if multiple mode bits were allowed, they could cause memory leaks: if both `FT_OPEN_STREAM` and `stream` are set along with either `FT_OPEN_MEMORY` or `FT_OPEN_PATHNAME`, then `FT_Stream_New` allocated a new stream but `FT_Open_Face` marked it as an 'external' stream, so the stream object was never released. * src/base/ftobjs.c (FT_Stream_New): Reject incompatible `FT_OPEN_XXX` flags. | |
