* Replace use of ctype functions with internal version where only ASCII chars ↵Adrian Johnson2022-04-091-2/+2
| | | | | | | | | are used In !309 Taylor R Campbell found a number of instances of ctype incorrectly passed a signed char. In many cases, where only ASCII characters are used, the code should have been using the cairo version of the ctype function to avoid locale issues.
* boilerplate: Use _cairo_malloc instead of mallocBryce Harrington2021-07-231-3/+4
| | | | | | | | | This changes most instances of malloc() calls to use Cairo's safer _cairo_malloc(). The malloc() call in the implementation of boilerplate's xmalloc() is not changed since it already includes a size=0 check. Signed-off-by: Bryce Harrington <bryce@osg.samsung.com>

* Retire dummy cairo-version.h header to fix meson subproject buildTim-Philipp Müller2020-09-291-6/+0
| | | | | | | | | | | | | | It was originally added to make bisecting easier, but has outlived its usefuleness now. Going forward we'll have just a single cairo-version.h header file, the one with the real version numbers. This is needed to fix the case where cairo is being built as a Meson subproject, but also simplifies things in general. Fixes #421
* image: prevent invalid ptr access for > 4GB imagesAdrian Johnson2017-11-071-1/+3
| | | | | | | | | | | | Image data is often accessed using: image->data + y * image->stride On 64-bit achitectures if the image data is > 4GB, this computation will overflow since both y and stride are 32-bit types.

* test: improve selective execution of Cairo tests based on FORMAT optionRavi Nanjundappa2014-08-141-13/+55
| | | | | | | | | | | | | | | | | | This patch improves the patch "test: Selective execution of Cairo tests based on FORMAT option" by extending the usage of FORMAT option even in the case of user not providing TARGETS= option For ex: (1). CAIRO_TESTS="zero-alpha" make test FORMAT=rgba This command runs the zero-alpha test for all the backends with argb32 content format and so on. (2). CAIRO_TESTS="zero-alpha" make test FORMAT=rgba,rgb This command runs the zero-alpha test for all the backends with argb32 and rgb24 content formats.

* test: Fix handling of dots in CAIRO_TEST_TARGETUli Schlachter2013-03-221-0/+2
| | | | | | | | | | | | | | | | | | Before this, the following happened: $ CAIRO_TEST_TARGET=image,xcb-render-0.0 make test Cannot find target 'image'. Known targets: image, [...] The reason for this is that _cairo_boilerplate_target_matches_name() doesn't get a null-terminated string, but instead has a pointer to the end of the string. However, strpbrk() expects a null-terminated argument and thus could return a result which points past the end of the input. This commit fixes exactly this.

* boilerplate: Use any2ppm from ANY2PPM env variableAndrea Canciani2012-02-231-2/+9
| | | | | | | | | If the environment variable ANY2PPM is set, use it as the path to the any2ppm program. Otherwise, default to "./any2ppm" as before. This makes it possible to set the ANY2PPM variable in the Makefile.win32 build system, which makes it possible to use the "test" target on the script backend.

* Introduce a new compositor architectureChris Wilson2011-09-121-9/+5
| | | | | | | | | | | | | | | | | | Having spent the last dev cycle looking at how we could specialize the compositors for various backends, we once again look for the commonalities in order to reduce the duplication. In part this is motivated by the idea that spans is a good interface for both the existent GL backend and pixman, and so they deserve a dedicated compositor. xcb/xlib target an identical rendering system and so they should be using the same compositor, and it should be possible to run that same compositor locally against pixman to generate reference tests. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> P.S. This brings massive upheaval (read breakage) I've tried delaying in order to fix as many things as possible but now this one patch does far, far, far too much. Apologies in advance for breaking your favourite backend, but trust me in that the end result will be much better. :)

That is the information the describe vfunc is supposed to provide.

* [boilerplate] Runtime library checkChris Wilson2009-08-291-3/+26
| | | | | | | For the purposes of benchmarking it is useful to run cairo-perf against a different library from the one it was compiled against. In order to do so, we need to check that the runtime library contains the required entry points for our targets - which we can check by using dlsym.

* Remove clip handling from generic surface layer.Chris Wilson2009-07-231-32/+68
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Handling clip as part of the surface state, as opposed to being part of the operation state, is cumbersome and a hindrance to providing true proxy surface support. For example, the clip must be copied from the surface onto the fallback image, but this was forgotten causing undue hassle in each backend. Another example is the contortion the meta surface endures to ensure the clip is correctly recorded. By contrast passing the clip along with the operation is quite simple and enables us to write generic handlers for providing surface wrappers. (And in the future, we should be able to write more esoteric wrappers, e.g. automatic 2x FSAA, trivially.) In brief, instead of the surface automatically applying the clip before calling the backend, the backend can call into a generic helper to apply clipping. For raster surfaces, clip regions are handled automatically as part of the composite interface. For vector surfaces, a clip helper is introduced to replay and callback into an intersect_clip_path() function as necessary. Whilst this is not primarily a performance related change (the change should just move the computation of the clip from the moment it is applied by the user to the moment it is required by the backend), it is important to track any potential regression: ppc: Speedups ======== image-rgba evolution-20090607-0 1026085.22 0.18% -> 672972.07 0.77%: 1.52x speedup ▌ image-rgba evolution-20090618-0 680579.98 0.12% -> 573237.66 0.16%: 1.19x speedup ▎ image-rgba swfdec-fill-rate-4xaa-0 460296.92 0.36% -> 407464.63 0.42%: 1.13x speedup ▏ image-rgba swfdec-fill-rate-2xaa-0 128431.95 0.47% -> 115051.86 0.42%: 1.12x speedup ▏ Slowdowns ========= image-rgba firefox-periodic-table-0 56837.61 0.78% -> 66055.17 3.20%: 1.09x slowdown ▏
* Remove the defunct test-meta surfaceChris Wilson2009-07-041-0/+35

* [boilerpate] Move target definition to backends.Chris Wilson2009-07-041-561/+78
| | | | | | | | | | | By moving the backend target definition out of the massive amlagamated block in cairo-boilerplate.c and into each of the cairo-boilerplate-backend.c, we make it much easier to add new targets as the information need only be entered in a single file and not scattered across three. However, updating the target interface means trawling across all the files -- except given that I found it difficult maintaining the single massive array I do not see this as an increase in the maintenance burden.
* [boilerplate] Read whole RGB lines at a timeChris Wilson2009-07-041-6/+7
| | | | | Rather than read+unpack each pixel, read in a whole RGB packed line and unpack the whole line in a single pass.
* Export meta-surfaceChris Wilson2009-07-031-6/+6
| | | | | | | | | | The meta-surface is a vital tool to record a trace of drawing commands in-memory. As such it is used throughout cairo. The value of such a surface is immediately obvious and should be applicable for many applications. The first such case is by cairo-test-trace which wants to record the entire graph of drawing commands that affect a surface in the event of a failure.
* [boilerplate] Propagate original error from create_from_png()Chris Wilson2009-06-281-0/+2
| | | | | | | | During cairo_boilerplate_get_image_surface_from_png() the original status returned by cairo_image_surface_create_from_png() could have been masked by inappropriate context construction when flattening or extracting. Simply check after creating the surface from the png file, and return immediately if in error.
* [test] Disable fallback16 testingChris Wilson2009-06-281-2/+2
| | | | | | | Only use the RGB16_565 surface as a source during testing. We presume that pixman is itself rigorously tested and the output is equivalent to the image surface. Enabling this test surface would require too large of a burden to maintain the reference images for the 16-bit backend.

In order to create such a surface, we need to update the boilerplate to use doubles instead of integers when specifying the surface size.
* [boilerplate] Implement a reference xlib surfaceChris Wilson2009-06-211-2/+12
| | | | | | | | | | | Create an xlib target that uses a separate display, specified by CAIRO_REFERENCE_DISPLAY, that can be used as a reference implementation for the normal display. So this can be used by cairo-trace-test to create a reference surface that mimics exactly the true surface, but if it targets an Xvfb display will be entirely rendered in software. If CAIRO_REFERENCE_DISPLAY is not set, the reference surface degrades into an xlib-fallback surface which is a close approximation (but still has behavioural differences).
* [test] Experiment with reference targetsChris Wilson2009-06-191-113/+141
| | | | | | Specify another boilerplate target to use as the reference for this target. We then use this in cairo-test-trace in preference to using the image surface. Still not perfect, though the framework is improving.
* Revert "[test] Make the xlib-fallback use the image refs."M Joonas Pihlaja2009-06-191-1/+1
| | | | | | | This reverts commit 903b39c30448d62e2cbf9d075c5256a333bd5d8f. The xlib-fallback actually renders mostly via traps at the moment, so staying with xlib refs is the right thing to do.
* Import Qt backend by MozillaVladimir Vukicevic2009-06-161-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | Written by Vladimir Vukicevic to enable integration with Qt embedded devices, this backend allows cairo code to target QPainter, and use it as a source for other cairo backends. This imports the sources from mozilla-central: http://mxr.mozilla.org/mozilla-central/find?text=&kind=text&string=cairo-qpainter renames them from cairo-qpainter to cairo-qt, and integrates the patch by Oleg Romashin: https://bugs.freedesktop.org/attachment.cgi?id=18953 And then attempts to restore 'make check' to full functionality. However: - C++ does not play well with the PLT symbol hiding, and leaks into the global namespace. 'make check' fails at check-plt.sh - Qt embeds a GUI into QApplication which it requires to construct any QPainter drawable, i.e. used by the boilerplate to create a cairo-qt surface, and this leaks fonts (cairo-ft-fonts no less) causing assertion failures that all cairo objects are accounted for upon destruction.
