gtk-doc fails make check for array as it insists that even the simplest
functions must have a long description and cannot be entirely described by
their arguments and return value.
Sanity check the arguments to _cairo_array_grow_by() such that the
array size does not overflow, similar to the defensive checking of
parameters to malloc.
Every time we assign or return a hard-coded error status wrap that value
with a call to _cairo_error(). So the idiom becomes:
status = _cairo_error (CAIRO_STATUS_NO_MEMORY);
or
return _cairo_error (CAIRO_STATUS_INVALID_DASH);
This ensures that a breakpoint placed on _cairo_error() will trigger
immediately cairo detects the error.
This patch was produced by running git-stripspace on all *.[ch] files
within cairo. Note that this script would have also created all the changes
from the previous commits to remove trailing whitespace.
This patch was produced with the following (GNU) sed script:
sed -i -r -e '/^[ \t]*\/?\*/ s/[ \t]+$//'
run on all *.[ch] files within cairo, (though I manually excluded
src/cairo-atsui-font.c which has a code line that appears as a comment
to this script).
This commit adds the following new functions to the cairo-ps API:
cairo_ps_surface_dsc_comment
cairo_ps_surface_dsc_begin_setup
cairo_ps_surface_dsc_begin_page_setup
Many thanks are due to Michael Sweet who provided invaluble guidance
during the design of this API.
It is hoped that with this API in place, basically all printer control
that is likely to be desired to be performed with cairo PostScript
output is now possible.
This commit augments the ps-features test to exercise the new API.
Fix buggy implementation of _cairo_array_snapshot by changing array->elements to be a pointer to a pointer. This extra level of indirection allows the snapshot array to point to a pointer which will itself get changed when new storage is needed for a growing array. Previously, the snapshot would be left pointing at stale storage.
Fix to call _cairo_array_index rather than grabbing array->elements directly and casting (which cast is now wrong with the change in implementation of array->index).
Add _cairo_array_init_snapshot and checks for is_snapshot throughout.
Add a new surface->backend->snapshot function.
Implement _cairo_meta_surface_snapshot and _cairo_meta_surface_acquire/release_source_image. Change _cairo_meta_surface_create to require the width and height in pixels to be used when replaying for purposed of _cairo_meta_surface_aquire_source_image.
Track change in prototype of _cairo_meta_surface_create. Implement _cairo_ps_surface_snapshot by deferring down into _cairo_meta_surface_snapshot.
Add new function to be used instead of the abuse of pasing data=NULL to cairo_pdf_ft_font_write.
Just return a status now instead of a pointer to the written buffer, since cairo_pdf_ft_font_allocate_write_buffer should now be used instead when a pointer is needed.
Switch to use cairo_pdf_ft_font_allocate_write_buffer.
Fix use of uninitialized status value.
initialization just to keep the compiler quiet about possibly uninitialized variables.
Cleanup to not rely on undocumented copy-avoidance in _cairo_array_append.
Track change in number of arguments and return value of _cairo_array_append.
Change functions to return type of void:
cairo_scaled_font_extents cairo_surface_finish
Add new functions to query object status:
cairo_scaled_font_status cairo_surface_status
Implementation of new error handling scheme for cairo_surface_t and cairo_scaled_font_t.
Track change in return value of cairo_surface_finish.
src/cairo-array.c src/cairoint.h src/cairo-surface.c: Refactor user data code from cairo-surface.c into cairo_user_data_array_t.
Switch these types to be like cairo_surface_t where the generic code frees the wrapper object.
src/cairo-atsui-font.c src/cairo-ft-font.c src/cairo-win32-font.c: Fix up for the above changes.
Implement a complicated mutual-referencing scheme to make sure that a face from cairo_ft_font_face_create_for_ft_face() is freed only when the FT_Face is no longer needed.
Update the docs to describe how to figure out when the FT_Face can be freed.
Fix refcount leaks when creating fonts.
Remove excess call to _cairo_unscaled_font_reference().
Remove stray initialization of font matrix to the identity.
test/user-data.c: Fix a bug when setting/unsetting a key with a free key slot before it, add that to the test case.
Don't append an element when user_data is NULL.
Change type of 'surface' argument in show_glyphs to void * as it is for all other surface virtual functions.
Update accordingly.
Add check for endianess.
Fix bug in array growing loop. (_cairo_array_append): Accept NULL for elements argument, in which case we just allocate space in the array.
