Behdad Esfahbod 0aa400b1 2025-02-15T23:19:44 [decycler] Implement an efficient graph cycle detector This is an algorithm I came up with, based on the Floyd's Tortoise-Hare constant-memory linear-time linked-list cycle-detection algorithm. https://en.wikipedia.org/wiki/Cycle_detection#Floyd's_tortoise_and_hare It is linear-time and malloc-free. It *eventually* detects cycles, not immediately. The main different with Floyd's algorithm is that this algorithm detects cycles when one is traversing down a graph, not just a linked list. Our existing cycle-detection algorithms use a set-of-integers, either hb_set_t, or more efficient in this case, hb_map_t. Those include at least one malloc, and as such show up on profiles. Port hb-ot-font COLRv1 to use the decycler instead of previous hb_map_t usage for cycle detection. benchmark-font paint_glyph on NotoColorEmoji-Regular.ttf: Before: 8ms; After: 5.5ms. No cycle detection: 5.5ms. FT COLRv1 API is so slow (174ms) it's not worth porting to this. Other graphs (VARC, etc) to be ported. Test and documentation to be added.
Behdad Esfahbod 0bb72eee 2025-02-18T00:44:29 [decycler] Turn off compiler warning ../src/OT/Var/VARC/../../../hb-decycler.hh:108:25: warning: storing the address of local variable ‘node’ in ‘*&c_15(D)->layers_decycler.hb_decycler_t::tortoise’ [-Wdangling-pointer=]
Behdad Esfahbod c84e9b95 2025-02-17T15:08:03 [decycler] Change value type from unsigned to uintptr_t Since the node struct is gonna be 3*sizeof(void*) bytes anyway, change value type to use the full space available.
Behdad Esfahbod 1c18646d 2025-02-17T15:06:27 [decycler] Reduce stack use, kinda Move the bool to the decycler from the node. The value can now become a full pointer size (next commit).

Khaled Hosny ff3aaece 2025-02-10T14:25:58 [test/shape-plan] Add another test and some comments
Khaled Hosny cf336f17 2025-02-10T14:15:25 [shape-plan] Rename hb_ot_shape_plan_get_features to get_feature_tags Simplify the API by returning only feature tags. The users of this API would be interested only in feature enabled by default and whether the feature is globally or partially enabled wouldn’t be of much interest in that case. For user features, the user of the API already have full access to them.
Khaled Hosny a7d7715f 2025-02-02T23:06:11 [shape-plan] Add hb_ot_shape_plan_get_features This should get the features on a shape plan after executing it. Initially I wanted to return an array of tags, but then there can be user features that are not enabled globally, so I thought returning hb_feature_t with value and range would be better. There is a TODO since I couldn’t figure out how to get the value and range from the feature mask. But also it may be overkill and a simple boolean indicating wither it is a global feature or not would be enough. I wounder also what should happen to non-user features that are applied selectively, like init or medi, does ot make sense to indicate whether they are global or not? This is inspired by the discussion in: https://github.com/fontforge/fontforge/pull/5522#pullrequestreview-2574321449, but it might be useful to other HarfBuzz users.
