61ba63f3a0 [win32] remove ignore_operators flag from win32 printing surface 
Remove the ignore_operators fallback-avoiding workaround; if apps
want that same behaviour, they'll have to implement it themselves
by taking care when calling cairo_set_operator().

a1633df6ee [cairo-scaled-font-subsets] Increment the sub_font counter after insertion. 
Do not modify the parent subsets->num_sub_font until after we have
successfully created the sub_font and inserted it into the hash table.

cf2f994a31 [cairo-paginated-surface] Propagate backend errors to the surface. 
If we call a srface backend function directly, then it our
responsibility to propagate any fatal errors to the surface.

3da62fdd28 [cairo-xlib-display] Rescan the displays list during shutdown. 
As we drop the list mutex whilst calling the hooks during the
XCloseDisplay callback, we must rescan the list when we reacquire the
mutex in order to remove the display from the list.

5ac7ba9821 [cairo-pdf-surface] Destroy local resources on failed surface creation. 
During _cairo_pdf_surface_create_for_stream_internal() destroy all
locally allocated resources and the output stream if we fail to create
the pdf surface or its paginated wrapper.

f1b6e2735c [cairo-ps-surface] Propagate errors from emit_pattern().

709f316036 Cleanup a couple of warnings for use of uninitialized statuses. 
The compiler spotted a couple of potential uses of an uninitialized
status variable - apply the obvious fixes.

2f22510e22 [cairo-xlib] Initialize the global mutexes. 
The xlib surface creation routines will eventually attempt to lock the
global _cairo_xlib_display_mutex. Under the default environment this is
a non-issue as the CAIRO_MUTEX_INITIALIZE/FINALIZE become no-ops under
pthreads. However, for the sake of correctness (i.e. to silence the
lockdep debugger!) insert a call to initialize the global mutexes at the
start of the public entry points.

60ffeecd48 [test-surfaces] Mark the test backend as static. 
There is no need to export the test surface backends, so mark them
static.

subsets ie _cairo_scaled_font_subsets_foreach_scaled() and co.

81243ee7ef [cairo-scaled-font] Mask cannot be NULL so remove redundant check. 
We either generate a mask for the glyphs or throw an error and bypass
the check, so at that point mask can never be NULL and we do not need
the test.

f3d921baca [cairo-scaled-font] Destroy the zombie font. 
If we do not transfer the font to the holdovers array (because it has
been removed from the cache and left in a zombie state), destroy it.
 2007-10-05 15:25:47 +01:00

41aab58f3a [cairo-surface] Add the usual guards to the API entry point. 
Add the checks for unmodifiable surfaces (snapshots, finished and error) to
cairo_surface_set_fallback_resolution.

dd0f2d851c [cairo-atomic] Hide compiler warnings for _cairo_status_set_error(). 
gcc treats cairo_status_t as an unsigned integer and so generates a
warning when passing it address as signed integer pointer to
_cairo_atomic_int_cmpxchg(). Use an ugly cast to hide the warning and
similarly to hide the warning about the unused result.

91d18eefe7 [cairo-type1-subset] Propagate error status (correctly!) 
Adrian Johnson pointed out a couple of mistakes in my previous attempt,
535e7c161b, to ensure propagation of errors
throughout the generation of the type1 subset.

This time the status member of the cairo_type1_font_subset_t is removed
in favour of simply return the error status from each function. This
completely avoids the issue of whether we overwrite a pre-existing error
status and confustion of status returns and the status member. The
removal of the status from the structure is possible due to its
short-lived nature - it is not exposed outside of the
_cairo_type1_subset_init() function, and is not shared by any other
piece of code.

853b29c56f [cairo-pdf-surface] Add some missing error propagation. 
Add a couple of returns where the status was being assigned but not
checked.

7601939a65 [cairo-deflate-stream] Return the nil stream if creating from an error stream. 
If _cairo_deflate_stream_create() is passed a stream in the error state,
return a stream also in the error state, namely the _cairo_output_stream_nil.
 2007-10-04 23:07:36 +01:00
Chris Wilson
717dcd1a2c [cairo-pdf-surface] Propagate resource allocation failure.

When propagating errors, check that we do not overwrite a pre-existing
error.
 2007-10-04 18:45:17 +01:00
Chris Wilson
bb8d4c0b14 [cairo-truetype-subset] Do mask error status returns. 
Be careful not to overwrite existing the error status when propagating
errors and to not blindly return INT_STATUS_UNSUPPORTED from
load_truetype_table() as this will mask fatal errors.
 2007-10-04 18:33:24 +01:00
Chris Wilson
37fd0d8967 [cairo-cff-subset] Propagate errors and review error paths.

Chris Wilson
add0959328 [cairo-debug] Finalize mutexes along with other static data. 
Initialize (so repeated calls of cairo_debug_reset_static_data() is
safe) and finalize the mutexes with the reset of the static data.

a4f20610af [cairo] Protect the getters when operating on the nil object. 
Put a guard that checks the context's status at the start of each
getter that prevents the function from trying to dereference NULL state.
Use the status, as opposed to the invalid reference count, for
consistency with the existing guards on some of the getters.

Ensure that all locally allocated (or referenced) resources are freed

the font.

4c32e6bfde [cairo-scaled-font] Return the error status from _cairo_scaled_font_set_error() 
Similar to the other _cairo_*_set_error() return the error status.
 2007-10-04 15:31:25 +01:00
Chris Wilson
06ae5f1ba3 [cairo-font-face] Set the error on the font. 
Similar to the other shared objects, store fatal errors on the shared
font_face. And do not return a cached reference to an object in an
error state.
 2007-10-04 15:26:09 +01:00
Chris Wilson
4cffdf2681 [cairo-ft-font] Always call _cairo_ft_unscaled_font_fini (). 
The _cairo_ft_unscaled_font_fini() was skipped during the destroy for
fonts generated by cairo_ft_font_face_create_for_ft_face(). However
this causes a mutex to be 'leaked' for each font.
