<!--LLVM PR SUMMARY COMMENT--> @llvm/pr-subscribers-lldb Author: Jacob Lalonde (Jlalond) <details> <summary>Changes</summary> Recently in #<!-- -->107731 this change was revereted due to excess memory size in `TestSkinnyCore`. This was due to a bug where a range's end was being passed as size. Creating massive memory ranges. Additionally, and requiring additional review, I added more unit tests and more verbose logic to the merging of save core memory regions. @<!-- -->jasonmolenda as an FYI. --- Patch is 48.83 KiB, truncated to 20.00 KiB below, full version: https://github.com/llvm/llvm-project/pull/107937.diff 25 Files Affected: - (modified) lldb/include/lldb/API/SBMemoryRegionInfo.h (+1-1) - (modified) lldb/include/lldb/API/SBSaveCoreOptions.h (+11) - (modified) lldb/include/lldb/Symbol/SaveCoreOptions.h (+9-2) - (added) lldb/include/lldb/Target/CoreFileMemoryRanges.h (+50) - (modified) lldb/include/lldb/Target/Process.h (+2-23) - (modified) lldb/include/lldb/Utility/RangeMap.h (+2) - (modified) lldb/include/lldb/lldb-enumerations.h (+1) - (modified) lldb/include/lldb/lldb-forward.h (+1) - (modified) lldb/include/lldb/lldb-private-interfaces.h (-1) - (modified) lldb/source/API/SBSaveCoreOptions.cpp (+11) - (modified) lldb/source/Commands/CommandObjectProcess.cpp (+1) - (modified) lldb/source/Plugins/ObjectFile/Mach-O/ObjectFileMachO.cpp (+4-2) - (modified) lldb/source/Plugins/ObjectFile/Mach-O/ObjectFileMachO.h (+1) - (modified) lldb/source/Plugins/ObjectFile/Minidump/MinidumpFileBuilder.cpp (+21-14) - (modified) lldb/source/Plugins/ObjectFile/Minidump/MinidumpFileBuilder.h (+3-2) - (modified) lldb/source/Plugins/ObjectFile/Minidump/ObjectFileMinidump.h (+1) - (modified) lldb/source/Plugins/ObjectFile/PECOFF/ObjectFilePECOFF.cpp (+1) - (modified) lldb/source/Plugins/ObjectFile/PECOFF/ObjectFilePECOFF.h (+1) - (modified) lldb/source/Symbol/SaveCoreOptions.cpp (+14) - (modified) lldb/source/Target/CMakeLists.txt (+1) - (added) lldb/source/Target/CoreFileMemoryRanges.cpp (+99) - (modified) lldb/source/Target/Process.cpp (+54-22) - (modified) lldb/test/API/functionalities/process_save_core_minidump/TestProcessSaveCoreMinidump.py (+149) - (modified) lldb/unittests/Process/Utility/CMakeLists.txt (+1) - (added) lldb/unittests/Process/Utility/CoreFileMemoryRangesTest.cpp (+205) ``````````diff diff --git a/lldb/include/lldb/API/SBMemoryRegionInfo.h b/lldb/include/lldb/API/SBMemoryRegionInfo.h index be55de4ead1fa8..f9a5dc993d7cb6 100644 --- a/lldb/include/lldb/API/SBMemoryRegionInfo.h +++ b/lldb/include/lldb/API/SBMemoryRegionInfo.h @@ -120,7 +120,7 @@ class LLDB_API SBMemoryRegionInfo { private: friend class SBProcess; friend class SBMemoryRegionInfoList; - + friend class SBSaveCoreOptions; friend class lldb_private::ScriptInterpreter; lldb_private::MemoryRegionInfo &ref(); diff --git a/lldb/include/lldb/API/SBSaveCoreOptions.h b/lldb/include/lldb/API/SBSaveCoreOptions.h index ba48ba5eaea5a0..c076d3ce6f7575 100644 --- a/lldb/include/lldb/API/SBSaveCoreOptions.h +++ b/lldb/include/lldb/API/SBSaveCoreOptions.h @@ -80,6 +80,17 @@ class LLDB_API SBSaveCoreOptions { /// \return True if the thread was removed, false if it was not in the list. bool RemoveThread(lldb::SBThread thread); + /// Add a memory region to save in the core file. + /// + /// \param region The memory region to save. + /// \returns An empty SBError upon success, or an error if the region is + /// invalid. + /// \note Ranges that overlapped will be unioned into a single region, this + /// also supercedes stack minification.
