[PATCH v2 0/8] MR1628: Draft: ntdll: Implement Low Fragmentation Heap.
Not completely sure if it's worth having for 8.0, but opening this to share the target I'm trying to reach. -- v2: ntdll: Implement Low Fragmentation Heap. ntdll: Introduce per-thread free lists for heap blocks. ntdll: Introduce a new BLOCK_FLAG_SPLIT heap block flag. ntdll: Introduce a new subheap thread affinity field. ntdll: Introduce a new heap block_init_used helper. ntdll: Introduce a new heap free_list_init helper. ntdll: Count allocations and automatically enable LFH. ntdll: Implement HeapCompatibilityInformation. https://gitlab.winehq.org/wine/wine/-/merge_requests/1628

Hi, It looks like your patch introduced the new failures shown below. Please investigate and fix them before resubmitting your patch. If they are not new, fixing them anyway would help a lot. Otherwise please ask for the known failures list to be updated. The tests also ran into some preexisting test failures. If you know how to fix them that would be helpful. See the TestBot job for the details: The full results can be found at: https://testbot.winehq.org/JobDetails.pl?Key=127189 Your paranoid android. === debian11 (32 bit report) === d2d1: d2d1: Timeout d3d10core: d3d10core: Timeout d3d10: effect: Timeout d3d11: d3d11: Timeout d3d8: visual: Timeout d3d9: device: Timeout visual: Timeout d3dcompiler_43: hlsl_d3d11: Timeout hlsl_d3d9: Timeout d3dcompiler_46: hlsl_d3d11: Timeout hlsl_d3d9: Timeout d3dcompiler_47: hlsl_d3d11: Timeout hlsl_d3d9: Timeout d3dx10_34: d3dx10: Timeout d3dx10_35: d3dx10: Timeout d3dx10_36: d3dx10: Timeout d3dx10_37: d3dx10: Timeout d3dx10_38: d3dx10: Timeout d3dx10_39: d3dx10: Timeout d3dx10_40: d3dx10: Timeout d3dx10_41: d3dx10: Timeout d3dx10_42: d3dx10: Timeout d3dx10_43: d3dx10: Timeout ddraw: ddraw1: Timeout ddraw2: Timeout ddraw4: Timeout ddraw7: Timeout visual: Timeout Report validation errors: mmdevapi:render timeout === debian11 (build log) === WineRunWineTest.pl:error: The task timed out === debian11b (32 bit WoW report) === kernel32: heap: Timeout === debian11b (64 bit WoW report) === kernel32: heap: Timeout
