At the top level, a minidump file is represented by a -// Minidump object. Like most other classes in this module, Minidump -// provides a Read method that initializes the object with information from -// the file. Most of the classes in this file are wrappers around the -// "raw" structures found in the minidump file itself, and defined in -// minidump_format.h. For example, each thread is represented by a -// MinidumpThread object, whose parameters are specified in an MDRawThread -// structure. A properly byte-swapped MDRawThread can be obtained from a -// MinidumpThread easily by calling its thread() method. -// -// Most of the module lazily reads only the portion of the minidump file -// necessary to fulfill the user's request. Calling Minidump::Read -// only reads the minidump's directory. The thread list is not read until -// it is needed, and even once it's read, the memory regions for each -// thread's stack aren't read until they're needed. This strategy avoids -// unnecessary file input, and allocating memory for data in which the user -// has no interest. Note that although memory allocations for a typical -// minidump file are not particularly large, it is possible for legitimate -// minidumps to be sizable. A full-memory minidump, for example, contains -// a snapshot of the entire mapped memory space. Even a normal minidump, -// with stack memory only, can be large if, for example, the dump was -// generated in response to a crash that occurred due to an infinite- -// recursion bug that caused the stack's limits to be exceeded. Finally, -// some users of this library will unfortunately find themselves in the -// position of having to process potentially-hostile minidumps that might -// attempt to cause problems by forcing the minidump processor to over- -// allocate memory. -// -// Memory management in this module is based on a strict -// you-don't-own-anything policy. The only object owned by the user is -// the top-level Minidump object, the creation and destruction of which -// must be the user's own responsibility. All other objects obtained -// through interaction with this module are ultimately owned by the -// Minidump object, and will be freed upon the Minidump object's destruction. -// Because memory regions can potentially involve large allocations, a -// FreeMemory method is provided by MinidumpMemoryRegion, allowing the user -// to release data when it is no longer needed. Use of this method is -// optional but recommended. If freed data is later required, it will -// be read back in from the minidump file again. -// -// There is one exception to this memory management policy: -// Minidump::ReadString will return a string object to the user, and the user -// is responsible for its deletion. -// -// Author: Mark Mentovai - -#ifndef PROCESSOR_MINIDUMP_H__ -#define PROCESSOR_MINIDUMP_H__ - - -// TODO(mmentovai): is it ok to include non- header in .h? -#include -#include -#include - -#include "processor/minidump_format.h" -#include "processor/memory_region.h" -#include "processor/range_map.h" - - -namespace google_airbag { - - -using std::map; -using std::string; -using std::vector; - - -class Minidump; - - -// MinidumpObject is the base of all Minidump* objects except for Minidump -// itself. -class MinidumpObject { - public: - virtual ~MinidumpObject() {} - - protected: - explicit MinidumpObject(Minidump* minidump); - - // Refers to the Minidump object that is the ultimate parent of this - // Some MinidumpObjects are owned by other MinidumpObjects, but at the - // root of the ownership tree is always a Minidump.
