+// ExceptionHandler can write a minidump file when an exception occurs,
+// or when WriteMinidump() is called explicitly by your program.
+//
+// To have the exception handler write minidumps when an uncaught exception
+// (crash) occurs, you should create an instance early in the execution
+// of your program, and keep it around for the entire time you want to
+// have crash handling active (typically, until shutdown).
+//
+// If you want to write minidumps without installing the exception handler,
+// you can create an ExceptionHandler with install_handler set to false,
+// then call WriteMinidump. You can also use this technique if you want to
+// use different minidump callbacks for different call sites.
+//
+// In either case, a callback function is called when a minidump is written,
+// which receives the unqiue id of the minidump. The caller can use this
+// id to collect and write additional application state, and to launch an
+// external crash-reporting application.
+//
+// It is important that creation and destruction of ExceptionHandler objects
+// be nested cleanly, when using install_handler = true.
+// Avoid the following pattern:
+// ExceptionHandler *e = new ExceptionHandler(...);
+// ExceptionHandler *f = new ExceptionHandler(...);
+// delete e;
+// This will put the exception filter stack into an inconsistent state.

+Conversions between UTF32, UTF-16, and UTF-8. Source code file.
+Author: Mark E. Davis, 1994.
+Rev History: Rick McGowan, fixes & updates May 2001.
+Sept 2001: fixed const & error conditions per
+mods suggested by S. Parent & A. Lillich.
+June 2002: Tim Dodd added detection and handling of incomplete
+source sequences, enhanced error detection, added casts
+to eliminate compiler warnings.
+July 2003: slight mods to back out aggressive FFFE detection.
+Jan 2004: updated switches in from-UTF8 conversions.
+Oct 2004: updated to use UNI_MAX_LEGAL_UTF32 in UTF-32 conversions.
+
+See the header file "ConvertUTF.h" for complete documentation.

+
+Conversions between UTF32, UTF-16, and UTF-8. Header file.
+
+Several funtions are included here, forming a complete set of
+conversions between the three formats. UTF-7 is not included
+here, but is handled in a separate source file.
+
+Each of these routines takes pointers to input buffers and output
+buffers. The input buffers are const.
+
+Each routine converts the text between *sourceStart and sourceEnd,
+putting the result into the buffer between *targetStart and
+targetEnd. Note: the end pointers are *after* the last item: e.g.
+*(sourceEnd - 1) is the last item.
+
+The return result indicates whether the conversion was successful,
+and if not, whether the problem was in the source or target buffers.
+(Only the first encountered problem is indicated.)
+
+After the conversion, *sourceStart and *targetStart are both
+updated to point to the end of last text successfully converted in
+the respective buffers.
+
+Input parameters:
+sourceStart - pointer to a pointer to the source buffer.
+The contents of this are modified on return so that
+it points at the next thing to be converted.
+targetStart - similarly, pointer to pointer to the target buffer.
+sourceEnd, targetEnd - respectively pointers to the ends of the
+two buffers, for overflow checking only.
+
+These conversion functions take a ConversionFlags argument. When this
+flag is set to strict, both irregular sequences and isolated surrogates
+will cause an error. When the flag is set to lenient, both irregular
+sequences and isolated surrogates are converted.
+
+Whether the flag is strict or lenient, all illegal sequences will cause
+an error return. This includes sequences such as: <F4 90 80 80>, <C0 80>,
+or <A0> in UTF-8, and values above 0x10FFFF in UTF-32. Conformant code
+must check for illegal sequences.
+
+When the flag is set to lenient, characters over 0x10FFFF are converted
+to the replacement character; otherwise (when the flag is set to strict)
+they constitute an error.
+
+Output parameters:
+The value "sourceIllegal" is returned from some routines if the input
+sequence is malformed. When "sourceIllegal" is returned, the source
+value will point to the illegal value that caused the problem. E.g.,
+in UTF-8 when a sequence is malformed, it points to the start of the
+malformed sequence.

+ // exception-handling data, and to make the data easier to work with
+ // in memory --- for example, to allow it to be placed in read-only
+ // memory even when describing position-independent code.
+ //
+ // In particular, exception handling data can select a number of
+ // different encodings for pointers that appear in the data, as
+ // described by the DwarfPointerEncoding enum. There are actually
+ // four axes(!) to the encoding:
+ //
+ // - The pointer size: pointers can be 2, 4, or 8 bytes long, or use
+ // the DWARF LEB128 encoding.
+ //
+ // - The pointer's signedness: pointers can be signed or unsigned.
+ //
+ // - The pointer's base address: the data stored in the exception
+ // handling data can be the actual address (that is, an absolute
+ // pointer), or relative to one of a number of different base
+ // addreses --- including that of the encoded pointer itself, for
+ // a form of "pc-relative" addressing.
+ //
+ // - The pointer may be indirect: it may be the address where the
+ // true pointer is stored. (This is used to refer to things via
+ // global offset table entries, program linkage table entries, or
+ // other tricks used in position-independent code.)
+ //
+ // There are also two options that fall outside that matrix
+ // altogether: the pointer may be omitted, or it may have padding to
+ // align it on an appropriate address boundary. (That last option
+ // may seem like it should be just another axis, but it is not.)

+ // SECTION_BASE, and that the start of its buffer in our own memory

+
+// dwarf2reader::CompilationUnit is a simple and direct parser for
+// DWARF data, but its handler interface is not convenient to use. In
+// particular:
+//
+// - CompilationUnit calls Dwarf2Handler's member functions to report
+// every attribute's value, regardless of what sort of DIE it is.
+// As a result, the ProcessAttributeX functions end up looking like
+// this:
+//
+// switch (parent_die_tag) {
+// case DW_TAG_x:
+// switch (attribute_name) {
+// case DW_AT_y:
+// handle attribute y of DIE type x
+// ...
+// } break;
+// ...
+// }
+//
+// In C++ it's much nicer to use virtual function dispatch to find
+// the right code for a given case than to switch on the DIE tag
+// like this.
+//
+// - Processing different kinds of DIEs requires different sets of
+// data: lexical block DIEs have start and end addresses, but struct
+// type DIEs don't. It would be nice to be able to have separate
+// handler classes for separate kinds of DIEs, each with the members
+// appropriate to its role, instead of having one handler class that
+// needs to hold data for every DIE type.
+//
+// - There should be a separate instance of the appropriate handler
+// class for each DIE, instead of a single object with tables
+// tracking all the dies in the compilation unit.
+//
+// - It's not convenient to take some action after all a DIE's
+// attributes have been seen, but before visiting any of its
+// children. The only indication you have that a DIE's attribute
+// list is complete is that you get either a StartDIE or an EndDIE
+// call.
+//
+// - It's not convenient to make use of the tree structure of the
+// DIEs. Skipping all the children of a given die requires
+// maintaining state and returning false from StartDIE until we get
+// an EndDIE call with the appropriate offset.
+//
+// This interface tries to take care of all that. (You're shocked, I'm sure.)
+//
+// Using the classes here, you provide an initial handler for the root
+// DIE of the compilation unit. Each handler receives its DIE's
+// attributes, and provides fresh handler objects for children of
+// interest, if any. The three classes are:
+//
+// - DIEHandler: the base class for your DIE-type-specific handler
+// classes.
+//
+// - RootDIEHandler: derived from DIEHandler, the base class for your
+// root DIE handler class.
+//
+// - DIEDispatcher: derived from Dwarf2Handler, an instance of this
+// invokes your DIE-type-specific handler objects.
+//
+// In detail:
+//
+// - Define handler classes specialized for the DIE types you're
+// interested in. These handler classes must inherit from
+// DIEHandler. Thus:
+//
+// class My_DW_TAG_X_Handler: public DIEHandler { ... };
+// class My_DW_TAG_Y_Handler: public DIEHandler { ... };
+//
+// DIEHandler subclasses needn't correspond exactly to single DIE
+// types, as shown here; the point is that you can have several
+// different classes appropriate to different kinds of DIEs.
+//
+// - In particular, define a handler class for the compilation
+// unit's root DIE, that inherits from RootDIEHandler:
+//
+// class My_DW_TAG_compile_unit_Handler: public RootDIEHandler { ... };
+//
+// RootDIEHandler inherits from DIEHandler, adding a few additional
+// member functions for examining the compilation unit as a whole,
+// and other quirks of rootness.
+//
+// - Then, create a DIEDispatcher instance, passing it an instance of
+// your root DIE handler class, and use that DIEDispatcher as the
+// dwarf2reader::CompilationUnit's handler:
+//
+// My_DW_TAG_compile_unit_Handler root_die_handler(...);
+// DIEDispatcher die_dispatcher(&root_die_handler);
+// CompilationUnit reader(sections, offset, bytereader, &die_dispatcher);
+//
+// Here, 'die_dispatcher' acts as a shim between 'reader' and the
+// various DIE-specific handlers you have defined.
+//
+// - When you call reader.Start(), die_dispatcher behaves as follows,
+// starting with your root die handler and the compilation unit's
+// root DIE:
+//
+// - It calls the handler's ProcessAttributeX member functions for
+// each of the DIE's attributes.
+//
+// - It calls the handler's EndAttributes member function. This
+// should return true if any of the DIE's children should be
+// visited, in which case:
+//
+// - For each of the DIE's children, die_dispatcher calls the
+// DIE's handler's FindChildHandler member function. If that
+// returns a pointer to a DIEHandler instance, then
+// die_dispatcher uses that handler to process the child, using
+// this procedure recursively. Alternatively, if
+// FindChildHandler returns NULL, die_dispatcher ignores that
+// child and its descendants.
+//
+// - When die_dispatcher has finished processing all the DIE's
+// children, it invokes the handler's Finish() member function,
+// and destroys the handler. (As a special case, it doesn't
+// destroy the root DIE handler.)
+//
+// This allows the code for handling a particular kind of DIE to be
+// gathered together in a single class, makes it easy to skip all the
+// children or individual children of a particular DIE, and provides

+// This class is a reader for DWARF's Call Frame Information. CFI
+// describes how to unwind stack frames --- even for functions that do
+// not follow fixed conventions for saving registers, whose frame size
+// varies as they execute, etc.
+//
+// CFI describes, at each machine instruction, how to compute the
+// stack frame's base address, how to find the return address, and
+// where to find the saved values of the caller's registers (if the
+// callee has stashed them somewhere to free up the registers for its
+// own use).
+//
+// For example, suppose we have a function whose machine code looks
+// like this (imagine an assembly language that looks like C, for a
+// machine with 32-bit registers, and a stack that grows towards lower
+// addresses):
+//
+// func: ; entry point; return address at sp
+// func+0: sp = sp - 16 ; allocate space for stack frame
+// func+1: sp[12] = r0 ; save r0 at sp+12
+// ... ; other code, not frame-related
+// func+10: sp -= 4; *sp = x ; push some x on the stack
+// ... ; other code, not frame-related
+// func+20: r0 = sp[16] ; restore saved r0
+// func+21: sp += 20 ; pop whole stack frame
+// func+22: pc = *sp; sp += 4 ; pop return address and jump to it
+//
+// DWARF CFI is (a very compressed representation of) a table with a
+// row for each machine instruction address and a column for each
+// register showing how to restore it, if possible.
+//
+// A special column named "CFA", for "Canonical Frame Address", tells how
+// to compute the base address of the frame; registers' entries may
+// refer to the CFA in describing where the registers are saved.
+//
+// Another special column, named "RA", represents the return address.
+//
+// For example, here is a complete (uncompressed) table describing the
+// function above:
+//
+// insn cfa r0 r1 ... ra
+// =======================================
+// func+0: sp cfa[0]
+// func+1: sp+16 cfa[0]
+// func+2: sp+16 cfa[-4] cfa[0]
+// func+11: sp+20 cfa[-4] cfa[0]
+// func+21: sp+20 cfa[0]
+// func+22: sp cfa[0]
+//
+// Some things to note here:
+//
+// - Each row describes the state of affairs *before* executing the
+// instruction at the given address. Thus, the row for func+0
+// describes the state before we allocate the stack frame. In the
+// next row, the formula for computing the CFA has changed,
+// reflecting that allocation.
+//
+// - The other entries are written in terms of the CFA; this allows
+// them to remain unchanged as the stack pointer gets bumped around.
+// For example, the rule for recovering the return address (the "ra"
+// column) remains unchanged throughout the function, even as the
+// stack pointer takes on three different offsets from the return
+// address.
+//
+// - Although we haven't shown it, most calling conventions designate
+// "callee-saves" and "caller-saves" registers. The callee must
+// preserve the values of callee-saves registers; if it uses them,
+// it must save their original values somewhere, and restore them
+// before it returns. In contrast, the callee is free to trash
+// caller-saves registers; if the callee uses these, it will
+// probably not bother to save them anywhere, and the CFI will
+// probably mark their values as "unrecoverable".
+//
+// (However, since the caller cannot assume the callee was going to
+// save them, caller-saves registers are probably dead in the caller
+// anyway, so compilers usually don't generate CFA for caller-saves
+// registers.)
+//
+// - Exactly where the CFA points is a matter of convention that
+// depends on the architecture and ABI in use. In the example, the
+// CFA is the value the stack pointer had upon entry to the
+// function, pointing at the saved return address. But on the x86,
+// the call frame information generated by GCC follows the
+// convention that the CFA is the address *after* the saved return
+// address.
+//
+// But by definition, the CFA remains constant throughout the
+// lifetime of the frame. This makes it a useful value for other
+// columns to refer to. It is also gives debuggers a useful handle
+// for identifying a frame.
+//
+// If you look at the table above, you'll notice that a given entry is
+// often the same as the one immediately above it: most instructions
+// change only one or two aspects of the stack frame, if they affect
+// it at all. The DWARF format takes advantage of this fact, and
+// reduces the size of the data by mentioning only the addresses and
+// columns at which changes take place. So for the above, DWARF CFI
+// data would only actually mention the following:
+//
+// insn cfa r0 r1 ... ra
+// =======================================
+// func+0: sp cfa[0]
+// func+1: sp+16
+// func+2: cfa[-4]
+// func+11: sp+20
+// func+21: r0
+// func+22: sp
+//
+// In fact, this is the way the parser reports CFI to the consumer: as
+// a series of statements of the form, "At address X, column Y changed
+// to Z," and related conventions for describing the initial state.
+//
+// Naturally, it would be impractical to have to scan the entire
+// program's CFI, noting changes as we go, just to recover the
+// unwinding rules in effect at one particular instruction. To avoid
+// this, CFI data is grouped into "entries", each of which covers a
+// specified range of addresses and begins with a complete statement
+// of the rules for all recoverable registers at that starting
+// address. Each entry typically covers a single function.
+//
+// Thus, to compute the contents of a given row of the table --- that
+// is, rules for recovering the CFA, RA, and registers at a given
+// instruction --- the consumer should find the entry that covers that
+// instruction's address, start with the initial state supplied at the
+// beginning of the entry, and work forward until it has processed all
+// the changes up to and including those for the present instruction.
+//
+// There are seven kinds of rules that can appear in an entry of the
+// table:
+//
+// - "undefined": The given register is not preserved by the callee;
+// its value cannot be recovered.
+//
+// - "same value": This register has the same value it did in the callee.
+//
+// - offset(N): The register is saved at offset N from the CFA.
+//
+// - val_offset(N): The value the register had in the caller is the
+// CFA plus offset N. (This is usually only useful for describing
+// the stack pointer.)
+//
+// - register(R): The register's value was saved in another register R.
+//
+// - expression(E): Evaluating the DWARF expression E using the
+// current frame's registers' values yields the address at which the
+// register was saved.
+//
+// - val_expression(E): Evaluating the DWARF expression E using the
+// current frame's registers' values yields the value the register
+// had in the caller.

+ //
+ // There are two differences between the call frame information described

+ //
+ // - Exception handling data uses uses a different format for call frame

+ // refer to their CIEs, and the way the end of the series of entries is
+ // determined are all slightly different.
+ //
+ // If the constructor's EH_FRAME argument is true, then the
+ // CallFrameInfo parses the entry headers as Linux C++ exception
+ // handling data. If EH_FRAME is false or omitted, the CallFrameInfo
+ // parses standard DWARF call frame information.
+ //
+ // - Linux C++ exception handling data uses CIE augmentation strings
+ // beginning with 'z' to specify the presence of additional data after
+ // the CIE and FDE headers and special encodings used for addresses in
+ // frame description entries.
+ //
+ // CallFrameInfo can handle 'z' augmentations in either DWARF CFI or

+ // for details about the additional information one might find in
+ // 'z'-augmented data.
+ //
+ // Thus:
+ //
+ // - If you are parsing standard DWARF CFI, as found in a .debug_frame
+ // section, you should pass false for the EH_FRAME argument, or omit
+ // it, and you need not worry about providing READER with the
+ // additional base addresses.
+ //
+ // - If you want to parse Linux C++ exception handling data from a
+ // .eh_frame section, you should pass EH_FRAME as true, and call
+ // READER's Set*Base member functions before calling our Start method.
+ //
+ // - If you want to parse DWARF CFI that uses the 'z' augmentations

+// MachMessage: a wrapper for a mach message of the following form
+// mach_msg_header_t
+// mach_msg_body_t
+// optional descriptors
+// optional extra message data
+//
+// MachReceiveMessage and MachSendMessage subclass MachMessage

+//
+// ReceivePort:
+// Represents a mach port for which we have receive rights
+//
+// MachPortSender:
+// Represents a mach port for which we have send rights
+//
+// Here's an example to receive a message on a server port:
+//
+// // This creates our named server port
+// ReceivePort receivePort("com.Google.MyService");
+//
+// MachReceiveMessage message;
+// kern_return_t result = receivePort.WaitForMessage(&message, 0);

+//
+// char *messageString = message.GetData();
+//
+// printf("message string = %s\n", messageString);
+// }
+//
+// Here is an example of using these classes to send a message to this port:
+//
+// // send to already named port
+// MachPortSender sender("com.Google.MyService");
+// MachSendMessage message(57); // our message ID is 57
+//
+// // add some ports to be translated for us
+// message.AddDescriptor(mach_task_self()); // our task
+// message.AddDescriptor(mach_thread_self()); // this thread
+//
+// char messageString[] = "Hello server!\n";

+// using_std_string.h: Allows building this code in environments where
+// global string (::string) exists.
+//
+// The problem:
+// -------------
+// Let's say you want to build this code in an environment where a global
+// string type is defined (i.e. ::string). Now, let's suppose that ::string
+// is different that std::string and you'd like to have the option to easily
+// choose between the two string types. Ideally you'd like to control which
+// string type is chosen by simply #defining an identifier.
+//
+// The solution:
+// -------------
+// #define HAS_GLOBAL_STRING somewhere in a global header file and then
+// globally replace std::string with string. Then include this header
+// file everywhere where string is used. If you want to revert back to
+// using std::string, simply remove the #define (HAS_GLOBAL_STRING).

+ *
+ * (This is C99 source, please don't corrupt it with C++.)
+ *
+ * This file contains the necessary definitions to read minidump files
+ * produced on amd64. These files may be read on any platform provided
+ * that the alignments of these structures on the processing system are
+ * identical to the alignments of these structures on the producing system.
+ * For this reason, precise-sized types are used. The structures defined
+ * by this file have been laid out to minimize alignment problems by ensuring
+ * ensuring that all members are aligned on their natural boundaries. In
+ * In some cases, tail-padding may be significant when different ABIs specify
+ * different tail-padding behaviors. To avoid problems when reading or
+ * writing affected structures, MD_*_SIZE macros are provided where needed,
+ * containing the useful size of the structures without padding.
+ *
+ * Structures that are defined by Microsoft to contain a zero-length array
+ * are instead defined here to contain an array with one element, as
+ * zero-length arrays are forbidden by standard C and C++. In these cases,
+ * *_minsize constants are provided to be used in place of sizeof. For a
+ * cleaner interface to these sizes when using C++, see minidump_size.h.
+ *
+ * These structures are also sufficient to populate minidump files.
+ *
+ * These definitions may be extended to support handling minidump files
+ * for other CPUs and other operating systems.
+ *
+ * Because precise data type sizes are crucial for this implementation to
+ * function properly and portably in terms of interoperability with minidumps
+ * produced by DbgHelp on Windows, a set of primitive types with known sizes
+ * are used as the basis of each structure defined by this file. DbgHelp
+ * on Windows is assumed to be the reference implementation; this file
+ * seeks to provide a cross-platform compatible implementation. To avoid
+ * collisions with the types and values defined and used by DbgHelp in the
+ * event that this implementation is used on Windows, each type and value
+ * defined here is given a new name, beginning with "MD". Names of the
+ * equivalent types and values in the Windows Platform SDK are given in
+ * comments.

+ * portions of DbgHelp.h from the Windows Platform SDK.
+ *
+ * (This is C99 source, please don't corrupt it with C++.)
+ *
+ * Structures that are defined by Microsoft to contain a zero-length array
+ * are instead defined here to contain an array with one element, as
+ * zero-length arrays are forbidden by standard C and C++. In these cases,
+ * *_minsize constants are provided to be used in place of sizeof. For a
+ * cleaner interface to these sizes when using C++, see minidump_size.h.
+ *
+ * These structures are also sufficient to populate minidump files.
+ *
+ * These definitions may be extended to support handling minidump files
+ * for other CPUs and other operating systems.
+ *
+ * Because precise data type sizes are crucial for this implementation to
+ * function properly and portably in terms of interoperability with minidumps
+ * produced by DbgHelp on Windows, a set of primitive types with known sizes
+ * are used as the basis of each structure defined by this file. DbgHelp
+ * on Windows is assumed to be the reference implementation; this file
+ * seeks to provide a cross-platform compatible implementation. To avoid
+ * collisions with the types and values defined and used by DbgHelp in the
+ * event that this implementation is used on Windows, each type and value
+ * defined here is given a new name, beginning with "MD". Names of the
+ * equivalent types and values in the Windows Platform SDK are given in
+ * comments.

+// use shared_ptr or std::auto_ptr if your needs are more complex.
+
+// *** NOTE ***
+// If your scoped_ptr is a class member of class FOO pointing to a
+// forward declared type BAR (as shown below), then you MUST use a non-inlined
+// version of the destructor. The destructor of a scoped_ptr (called from
+// FOO's destructor) must have a complete definition of BAR in order to
+// destroy it. Example:
+//
+// -- foo.h --
+// class BAR;
+//
+// class FOO {
+// public:
+// FOO();
+// ~FOO(); // Required for sources that instantiate class FOO to compile!
+//
+// private:
+// scoped_ptr<BAR> bar_;
+// };
+//
+// -- foo.cc --
+// #include "foo.h"
+// FOO::~FOO() {} // Empty, but must be non-inlined to FOO's class definition.
+
+// scoped_ptr_malloc added by Google
+// When one of these goes out of scope, instead of doing a delete or
+// delete[], it calls free(). scoped_ptr_malloc<char> is likely to see
+// much more use than any other specializations.
