(CR/LF), now they are UNIX (CR).
It seems like the base gyp scripts on Windows were confused about this and didn't handle it well, while using gyp through gclient worked perfectly. I did not investigate the causes further.

Added a test for the minidump generated by a pure virtual function call.
Changed the pure virtual function call handler so that it creates a minidump with Exception info and a stack.

exception_handler_death_test. It doesn't test anything else than death and exit.
Created the exception_handler_test that test the generation of dump and the dumps themselves.
Moved all dump analysis code from minidump to its right class DumpAnalysis. The class is used by both minidump_test and exception_handler_test. The tests are way simpler that way (ie. no handling of HANDLE).
minidump_test now uses the minidump_generator class instead of using Win32. It works well and pass all tests.
exception_handler now passes both the exception and assertion infos to the client to generate the dump. If one is NULL it's going to be handled correctly.
crash_generation_client can now RequestDump with both exception and assertion info.
minidump_generator returns both the mini and full dump string pointers, and output both (or either) depending on which was generated.
All original interfaces and method signature are still there, but call the new functions if possible.

I had to remove the dependency from base (was using FilePath and ScopedHandle, replaced them by standard std::wstring and HANDLE). Also removed the logging and the main from the original files.
This will serve as a base for testing breakpad's dump generation. It is kept like this for easier tracking.

The XCode project file has become encrufted with duplicate Executable

entries to make things neat again. It should have no effect on the

to TestAssembler::Section.
This patch helps the TestAssembler classes generate Mach-O object files for
use as test input.
This patch adds a new AppendCString overloading to TestAssembler::Section
for emitting null-terminated strings in fixed-length buffers, where the
string is truncated and the terminating null character omitted if the
string is too large for the buffer.
The patch includes unit tests for the new AppendCString overloading. It
also provides some for the existing overloading, which had been neglected.

Breakpad's Macintosh symbol dumper uses deprecated functions for
dealing with mixed-endianness code. This patch provides an overloaded
function, ByteSwap, that automatically chooses the OSSwap* functions
from <libkern/OSByteOrder.h> appropriate for its argument's
size.
This patch does *not* address warnings in src/common/mac/dump_syms.mm,
because that code is about to be replaced entirely; there's no reason to
bother reviewing a big, detailed patch against it.

any time.
It's possible to imagine an implementation of google_breakpad::Module in
which calling SetLoadAddress at different times as the Module is populated
would produce different output. For the Mac dumper, we'd like to depend on
its current behavior --- that the load address is subtracted off only when
writing the symbol file, and can be set at any time prior to that.
This patch makes that promise part of Module's contract, and adjusts the
test suite to verify that that promise is met.

outside functions.
This patch addresses two differences between Linux and Macintosh OS X STABS
data:
- StabsReader assumes that the STABS entries follow the conventions for
storing STABS data in object file sections (that is, .stabs and
.stabstr), rather than in the object files's linker symbol table. On Mac
OS X, STABS entries live in the Mach-O file's LC_SYMTAB load command,
along with all the other linker symbols; they are not grouped into units
by N_UNDF entries.
This patch adds a boolean argument to the StabsReader constructor
indicating whether the parser should treat N_UNDF entries as unit
boundaries; this argument should be true on Linux, and false on Mac. The
patch changes src/common/linux/dump_symbols.cc to pass this new argument.
- Mac OS X STABS place SLINE (line number) records immediately before the
FUN record for the function to which they belong, and the values of such
records are absolute, not relative to the function start.
This patch extends the parser to queue up such records and report them to
the handler when we do see the FUN record. The meaning of
StabsHandler::Line remains unchanged; existing handlers do not need to be
adjusted.
This patch also adds unit tests for the new parser behaviors.

tests into a fixture class. Pretty mechanical.

An N_FUN stabs with no name is an explicit end-of-function marker, whose
value is the size of the function. This patch changes the stabs reader to
recognize these and use them to compute the function's ending address,
instead of treating them as functions with no names and mysterious
addresses. It also adds appropriate unit tests.

All the other classes which receive debugging data from some sort of parser
and use it to populate a Module have names ending in "ToModule":
DwarfCUToModule, DwarfCFIToModule. Also, DumpStabsHandler doesn't actually
dump anything.
This patch renames the DumpStabsHandler class to StabsToModule, which is
more consistent and descriptive.

StabsReader simply applies a reinterpret_cast to treat the stab entry data
as an array of 'struct nlist' structures, making the parser specific on the
host endianness, word size, and alignment rules. On Mac OS X, a single fat
binary file may contain object files of different ABIs, of which the user
chooses one at run time.
This patch changes the parser to read the data using the google_breakpad::
ByteCursor class, which can handle different endiannesses and word sizes.
The StabsReader constructor now takes arguments indicating the endianness
of the data and the size of each entry's value field. The patch changes
src/common/linux/dump_symbols.cc to pass the new argument.
This patch changes the StabsReader unit tests to use the google_breakpad::
TestAssembler classes to generate test data, rather than reading it from a
file. This makes it easy to generate test data in various endiannesses and
word sizes. It also adds tests for the new parser behaviors.

Finalize is not called
The DumpStabsHandler class creates Module::Function objects as it processes
data from the StabsReader, but waits to add the Functions to the Module
until all parsing is complete and its Finalize member function is called,
so that it can compute line and function end addresses that the STABS data
may have left implicit.
If the DumpStabsHandler is destructed before its Finalize method is called,
it fails to free the Functions it has created, but not yet added to the
Module. (Adding a Function to a Module transfers ownership of the Function
to the Module.)
This adds a destructor to DumpStabsHandler which takes care of freeing any
Functions that it still owns.

At the moment, the mappings from register numbers appearing in DWARF CFI
and .eh_frame exception handling sections to the appropriate
processor-specific names are in src/common/linux/dump_syms.cc. However, the
numberings are (for the most part) the same on all platforms using DWARF,
so there's no reason those tables shouldn't be shared between the Linux and
Mac symbol dumpers.
This patch moves the tables into a nested class of DwarfCFIToModule, so
they the Mac dumper can use them when it is changed to use
DwarfCFIToModule.

by default.
In the process of pairing up DWARF source lines with the functions they
belong to, the dumper detects and warns about regions of functions that
have no source line information, and vice versa. However, this seems to
occur in real code frequently enough (although not often) that the warnings
may obscure more serious problems.
This patch makes those warnings disabled by default in
DwarfCUToModule::WarningReporter. It does not add a way for the dump_syms
user to enable them.

In order to dump call frame information held in .eh_frame sections, the
dumper needs to know the proper base address to use for pointers encoded
using the DW_EH_PE_textrel encoding. This should be the start of the .text
section. However, due to a cut-and-paste typo, the dumper was supplying the
base address of the ".got" section instead.

The Linux dumper's Makefile doesn't record the object files' dependence on
header files at all, just because I was too lazy to write them out and knew
I would forget to keep them up to date anyway. But I've wasted too much
time tracking down mysterious segmentation faults and other problems after
changing header files, and I know it's wasted others' time, too.

The comments don't accurately describe what the style guide says.
Regardless of what the style guide says, RTTI seems to make trouble in
practice, because so many people build with it disabled. Since only the
symbol dumper uses RTTI, not the client library, it may be practical for
people to simply enable RTTI for the dumper. Failing that, it may be best
in the long run to violate the style guide and make the code work sans
RTTI.

- Use manifest constants for 'z' augmentation letters.
- Fix typos and rearrange some code for legibility.

Breakpad Linux client: Simplify VerifyStackReadWithMultipleThreads unit test.
As written, the VerifyStackReadWithMultipleThreads unit test makes
assumptions about the layout of thread_function's stack frame. As a result,
the test will fail when compiled with some compilers, or built with certain
optimization levels.
As an extension to C++, the GNU compilers allow you to request that a
variable be placed in a specific register. Using this, we can have
thread_function put the thread id in place where the test can find it
reliably.

the minidump.
Having an exception of interest makes the resultant minidumps look just like
crash dumps, in that the processor can identify the "crashing" tread.
This means such minidumps can be classified by the stack signature, in contrast to the current state of things, in which all such dumps get lumped on a single pile.

This adds support for 'STACK CFI' records (DWARF CFI) to the AMD64
stack walker. This is necessary for the stack trace to include any
frames other than the youngest. Unit tests are included.
