cogl test-premult: Don't free texture data until CoglBitmap is freed According to the cogl_bitmap_new_for_data documentation, the data is not copied, so the application must keep the buffer alive for the lifetime of the CoglBitmap. Freeing it too early led to a use-after-free in the cogl unit tests. With that fixed, the test passes, so remove the known failure annotation. This AddressSanitizer trace is from the original cogl, but the bug and fix apply equally to mutter's fork of cogl: ==6223==ERROR: AddressSanitizer: heap-use-after-free on address 0x62100001a500 at pc 0x7f3e2d4e7f4e bp 0x7ffcd9c41f30 sp 0x7ffcd9c416e0 READ of size 4096 at 0x62100001a500 thread T0 #0 0x7f3e2d4e7f4d (/usr/lib/x86_64-linux-gnu/libasan.so.5+0x96f4d) #1 0x7f3e260c7f6b in util_copy_box ../src/gallium/auxiliary/util/u_surface.c:131 #2 0x7f3e268c6c10 in u_default_texture_subdata ../src/gallium/auxiliary/util/u_transfer.c:67 #3 0x7f3e26486459 in st_TexSubImage ../src/mesa/state_tracker/st_cb_texture.c:1480 #4 0x7f3e26487029 in st_TexImage ../src/mesa/state_tracker/st_cb_texture.c:1709 #5 0x7f3e26487029 in st_TexImage ../src/mesa/state_tracker/st_cb_texture.c:1691 #6 0x7f3e2644bdba in teximage ../src/mesa/main/teximage.c:3105 #7 0x7f3e2644bdba in teximage_err ../src/mesa/main/teximage.c:3132 #8 0x7f3e2644d84f in _mesa_TexImage2D ../src/mesa/main/teximage.c:3170 #9 0x7f3e2cd1f7df in _cogl_texture_driver_upload_to_gl driver/gl/gl/cogl-texture-driver-gl.c:347 #10 0x7f3e2ccd441b in allocate_from_bitmap driver/gl/cogl-texture-2d-gl.c:255 #11 0x7f3e2ccd441b in _cogl_texture_2d_gl_allocate driver/gl/cogl-texture-2d-gl.c:462 #12 0x7f3e2ce3a6c0 in cogl_texture_allocate cogl/cogl-texture.c:1398 #13 0x7f3e2ce3e116 in _cogl_texture_pre_paint cogl/cogl-texture.c:359 #14 0x7f3e2cdee177 in _cogl_pipeline_layer_pre_paint cogl/cogl-pipeline-layer.c:864 #15 0x7f3e2cd574af in _cogl_rectangles_validate_layer_cb cogl/cogl-primitives.c:542 #16 0x7f3e2cdd742f in cogl_pipeline_foreach_layer cogl/cogl-pipeline.c:735 #17 0x7f3e2cd5c8b0 in _cogl_framebuffer_draw_multitextured_rectangles cogl/cogl-primitives.c:658 #18 0x7f3e2cd60152 in cogl_rectangle cogl/cogl-primitives.c:858 #19 0x5570a71ed6a0 in check_texture tests/conform/test-premult.c:103 #20 0x5570a71ed946 in test_premult tests/conform/test-premult.c:159 #21 0x5570a71df0d6 in main tests/conform/test-conform-main.c:58 #22 0x7f3e2bcd809a in __libc_start_main ../csu/libc-start.c:308 #23 0x5570a71e0869 in _start (/home/smcv/src/debian/cogl/tests/conform/.libs/test-conformance+0x33869) 0x62100001a500 is located 0 bytes inside of 4096-byte region [0x62100001a500,0x62100001b500) freed by thread T0 here: #0 0x7f3e2d5581d7 in __interceptor_free (/usr/lib/x86_64-linux-gnu/libasan.so.5+0x1071d7) #1 0x5570a71ed58b in make_texture tests/conform/test-premult.c:69 previously allocated by thread T0 here: #0 0x7f3e2d558588 in malloc (/usr/lib/x86_64-linux-gnu/libasan.so.5+0x107588) #1 0x7f3e2d384500 in g_malloc ../../../glib/gmem.c:99 This was originally cogl!12. https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1274 Signed-off-by: Simon McVittie <smcv@debian.org>

Add support for per-vertex point sizes This adds a new function to enable per-vertex point size on a pipeline. This can be set with cogl_pipeline_set_per_vertex_point_size(). Once enabled the point size can be set either by drawing with an attribute named 'cogl_point_size_in' or by writing to the 'cogl_point_size_out' builtin from a snippet. There is a feature flag which must be checked for before using per-vertex point sizes. This will only be set on GL >= 2.0 or on GLES 2.0. GL will only let you set a per-vertex point size from GLSL by writing to gl_PointSize. This is only available in GL2 and not in the older GLSL extensions. The per-vertex point size has its own pipeline state flag so that it can be part of the state that affects vertex shader generation. Having to enable the per vertex point size with a separate function is a bit awkward. Ideally it would work like the color attribute where you can just set it for every vertex in your primitive with cogl_pipeline_set_color or set it per-vertex by just using the attribute. This is harder to get working with the point size because we need to generate a different vertex shader depending on what attributes are bound. I think if we wanted to make this work transparently we would still want to internally have a pipeline property describing whether the shader was generated with per-vertex support so that it would work with the shader cache correctly. Potentially we could make the per-vertex property internal and automatically make a weak pipeline whenever the attribute is bound. However we would then also need to automatically detect when an application is writing to cogl_point_size_out from a snippet.
