// The ExceptionHandler object installs signal handlers for a number of
// signals. We rely on the signal handler running on the thread which crashed
// in order to identify it. This is true of the synchronous signals (SEGV etc),
// but not true of ABRT. Thus, if you send ABRT to yourself in a program which
// uses ExceptionHandler, you need to use tgkill to direct it to the current
// thread.
//
// The signal flow looks like this:
//
// SignalHandler (uses a global stack of ExceptionHandler objects to find
// | one to handle the signal. If the first rejects it, try
// | the second etc...)
// V
// HandleSignal ----------------------------| (clones a new process which
// | | shares an address space with
// (wait for cloned | the crashed process. This
// process) | allows us to ptrace the crashed
// | | process)
// V V
// (set signal handler to ThreadEntry (static function to bounce
// SIG_DFL and rethrow, | back into the object)
// killing the crashed |
// process) V
// DoDump (writes minidump)
// |
// V
// sys_exit
//
// This code is a little fragmented. Different functions of the ExceptionHandler
// class run in a number of different contexts. Some of them run in a normal
// context and are easy to code, others run in a compromised context and the
// restrictions at the top of minidump_writer.cc apply: no libc and use the
// alternative malloc. Each function should have comment above it detailing the
// context which it runs in.

// ExceptionHandler can write a minidump file when an exception occurs,

//
// To have the exception handler write minidumps when an uncaught exception

// of your program, and keep it around for the entire time you want to
// have crash handling active (typically, until shutdown).
// (NOTE): There should be only be one this kind of exception handler
// object per process.
//
// 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 full path or file descriptor of the minidump. The
// caller can collect and write additional application state to that minidump,
// and launch an external crash-reporting application.
//
// Caller should try to make the callbacks as crash-friendly as possible,
// it should avoid use heap memory allocation as much as possible.

// If a FilterCallback returns true, Breakpad will continue processing,

// treat the exception as fully-handled, suppressing any other handlers from
// being notified of the exception. If the callback returns false, Breakpad
// will treat the exception as unhandled, and allow another handler to handle
// it. If there are no other handlers, Breakpad will report the exception to
// the system as unhandled, allowing a debugger or native crash dialog the

// 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.

The fall-through switches in UTF-8 reading code save a

do {

#ifndef COMMON_CONVERT_UTF_H_
#define COMMON_CONVERT_UTF_H_
/* ---------------------------------------------------------------------
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.

// 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).

/* minidump_format.h: A cross-platform reimplementation of minidump-related
* portions of DbgHelp.h from the Windows Platform SDK.
*
* (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

/* minidump_format.h: A cross-platform reimplementation of minidump-related
* 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
