From 6092b21d6e74a343f6019551c64723d7aced7c2e Mon Sep 17 00:00:00 2001 From: Elinor Fung Date: Fri, 6 Sep 2024 10:13:12 -0700 Subject: [PATCH] Move pinned heap handle table from `BaseDomain` to `AppDomain` and make callers go through the `AppDomain` (#107420) - Move the pinned heap handle table to `AppDomain` - This does make the current use in the `GlobalLoaderAllocator` (went through `SystemDomain`) and in EnC adding a static field (went through `AppDomain`) use the same table. They have the same lifetime. - Move `GetLoaderAllocator` (it already always returns the global one), `IsStringInterned`, `GetOrInternString` functions from `BaseDomain` to `AppDomain` --- src/coreclr/debug/daccess/dacdbiimpl.cpp | 2 +- src/coreclr/debug/daccess/enummem.cpp | 2 +- src/coreclr/debug/daccess/request.cpp | 9 +-- src/coreclr/vm/appdomain.cpp | 93 ++++++++---------------- src/coreclr/vm/appdomain.hpp | 43 +++++------ src/coreclr/vm/loaderallocator.cpp | 4 +- 6 files changed, 61 insertions(+), 92 deletions(-) diff --git a/src/coreclr/debug/daccess/dacdbiimpl.cpp b/src/coreclr/debug/daccess/dacdbiimpl.cpp index be5ee49e10b69..6309533648bb2 100644 --- a/src/coreclr/debug/daccess/dacdbiimpl.cpp +++ b/src/coreclr/debug/daccess/dacdbiimpl.cpp @@ -3672,7 +3672,7 @@ HRESULT DacDbiInterfaceImpl::GetLoaderHeapMemoryRanges(DacDbiArrayListGetLoaderAllocator(); + PTR_LoaderAllocator pGlobalAllocator = SystemDomain::GetGlobalLoaderAllocator(); _ASSERTE(pGlobalAllocator); EnumerateMemRangesForLoaderAllocator(pGlobalAllocator, &memoryRanges); diff --git a/src/coreclr/debug/daccess/enummem.cpp b/src/coreclr/debug/daccess/enummem.cpp index be3c1123ea416..7840bb29070cd 100644 --- a/src/coreclr/debug/daccess/enummem.cpp +++ b/src/coreclr/debug/daccess/enummem.cpp @@ -743,7 +743,7 @@ HRESULT ClrDataAccess::EnumMemDumpAppDomainInfo(CLRDataEnumMemoryFlags flags) if (flags == CLRDATA_ENUM_MEM_HEAP2) { - SystemDomain::System()->GetLoaderAllocator()->EnumMemoryRegions(flags); + SystemDomain::GetGlobalLoaderAllocator()->EnumMemoryRegions(flags); } AppDomain* appDomain = AppDomain::GetCurrentDomain(); diff --git a/src/coreclr/debug/daccess/request.cpp b/src/coreclr/debug/daccess/request.cpp index bbd2b96c9ba37..2be13b91e98aa 100644 --- a/src/coreclr/debug/daccess/request.cpp +++ b/src/coreclr/debug/daccess/request.cpp @@ -2838,7 +2838,7 @@ ClrDataAccess::GetAppDomainData(CLRDATA_ADDRESS addr, struct DacpAppDomainData * ZeroMemory(appdomainData, sizeof(DacpAppDomainData)); appdomainData->AppDomainPtr = PTR_CDADDR(pBaseDomain); - PTR_LoaderAllocator pLoaderAllocator = pBaseDomain->GetLoaderAllocator(); + PTR_LoaderAllocator pLoaderAllocator = SystemDomain::GetGlobalLoaderAllocator(); appdomainData->pHighFrequencyHeap = HOST_CDADDR(pLoaderAllocator->GetHighFrequencyHeap()); appdomainData->pLowFrequencyHeap = HOST_CDADDR(pLoaderAllocator->GetLowFrequencyHeap()); appdomainData->pStubHeap = HOST_CDADDR(pLoaderAllocator->GetStubHeap()); @@ -4065,8 +4065,7 @@ ClrDataAccess::TraverseVirtCallStubHeap(CLRDATA_ADDRESS pAppDomain, VCSHeapType SOSDacEnter(); - BaseDomain* pBaseDomain = PTR_BaseDomain(TO_TADDR(pAppDomain)); - VirtualCallStubManager *pVcsMgr = pBaseDomain->GetLoaderAllocator()->GetVirtualCallStubManager(); + VirtualCallStubManager *pVcsMgr = SystemDomain::GetGlobalLoaderAllocator()->GetVirtualCallStubManager(); if (!pVcsMgr) { hr = E_POINTER; @@ -4111,8 +4110,8 @@ HRESULT ClrDataAccess::GetDomainLoaderAllocator(CLRDATA_ADDRESS domainAddress, C SOSDacEnter(); - PTR_BaseDomain pDomain = PTR_BaseDomain(TO_TADDR(domainAddress)); - *pLoaderAllocator = pDomain != nullptr ?
