The test system is based on Google C++ Testing Framework and the
Google C++ Mocking Framework.
This includes a parser that turns human-readable input files ("mock
stabs") into .stab and .stabstr section contents, which we can then
pass to a StabsReader instance, using a handler object written with
GoogleMock. The 'make check' target in src/tools/linux/dump_syms runs
this.
The supplied input file is pretty small, but I've done coverage
testing, and it does cover the parser.
I thought the mock stabs parser would be less elaborate than it turned
out to be. Lesson learned.

If the input passed to a StabsReader instance contains a compilation
unit whose first entry is an N_SO with no name, the parser enters an
infinite loop. Since such entries mark the end of a compilation unit,
ProcessCompilationUnit should skip them.

Warning member.
The StabsHandler class should not provide a fallback definition for
its Warning member function that just throws away warning messages.
It should require the consumer to provide an appropriate definition.

Modern GNU compilers warn about the #inclusion of <ext/hash_map>; that
container is deprecated, and code should use <tr1/unordered_map>
instead. However, to stay within the boundaries of C++ '98, it's
probably fine just to use plain old std::map.
Breakpad uses hash_map in three cases:
o The DWARF reader's SectionMap type maps object file section names to
data. This map is consulted once per section kind per DWARF
compilation unit; it is not performance-critical.
o The Mac dump_syms tool uses it to map machine architectures to
section maps in Universal binaries. It's hard to imagine there
ever being more than two entries in such a map.
o The processor's BasicSourceLineResolver uses a hash_map to map file
numbers to file names. This is the map that will probably have the
most entries, but it's only accessed once per frame, after we've
found the frame's line entry.

their own class.
src/linux/common/module.h defines a new class, google_breakpad::Module,
that can represent the contents of a breakpad symbol file. Module::Write
writes a well-formed symbol file to the given stream.
src/linux/common/dump_symbols.cc can now lose its symbol-file-writing
code, and change DumpStabsHandler to populate a Module object, rather
than the old SymbolInfo/SourceFileInfo/... collection of types.
The code to compute function and line sizes, even in the absence of
reliable size data in STABS, is moved into a new Finalize method of
DumpStabsHandler, which is responsible for completing the Module's
contents.

With this patch, dump_symbols.cc no longer knows about the details of
the STABS debugging format; that is handled by the StabsReader class.
dump_symbols.cc provides a subclass of StabsHandler that builds
dump_symbols' own representation of the data.

char *.
Because the actual N_FUN strings in the .stabstr section contain type
information after the mangled name, representing this information
using a pointer into .stabstr, while efficient with memory, makes the
FuncInfo data structure STABS-specific: one must know the details of a
STABS N_FUN string's syntax to interpret FuncInfo::name. This patch
removes this STABS dependency from the data structure, and moves us
closer to having an appropriate structure for representing unified
STABS and DWARF data.

STABS strings for N_FUN entries contain a mangled function name,
followed by a colon, followed by type information. The type
information itself may contain colons; mangled names never contain
colons (they need to be legal assembly-language identifiers). So the
current code in src/common/linux/dump_symbols.cc:WriteOneFunction that
attempts to separate the mangled name from the STABS junk will
incorrectly include STABS junk in the name, causing demangling to
fail.
Applying the patch below results in changes like these in the symbol
file produced, where an unmangled name followed by STABS junk becomes
a properly demangled name:

In STABS, if one function's line number information contains an N_SOL
entry to switch to a new source file, then the next function's line
data should pick up in the same source file where the prior function
left off. However, the Linux dumper restarts each function in the
compilation unit's main source file. This patch fixes that, so that
the output attributes the lines in subsequent functions to the correct
source files.

structures
Let LineInfo structures point directly to their SourceLineInfo
structures, rather than holding the index of the file's name in the
.stabstr section in the early phases, and then later the holding
source_id of the file.
This is another step in the process of moving STABS-specific values
out of the types that represent the breakpad symbol data. When we're
done, the non-STABS structures will be something that we can populate
with both STABS and DWARF data --- or at least it will be more easily
replaced with such.

SourceFileInfoList entries.
STABS information introduces a compilation unit with an N_SO entry
whose address is the start address of the file and whose string is the
name of the compilation unit's main source file. However, STABS
entries can only hold one address, so STABS indicates the compilation
unit's ending address with an N_SO entry whose name is empty.
Currently, the dumper's data structures simply create SourceFileInfo
structures with empty names for these end-of-unit N_SO entries. We
want to remove STABS-specific characteristics from these structures so
that we can replace them with an input-format-independent structure.
This moves end-of-compilation-unit addresses out of the symbol table
structure, and into their own list of boundary addresses.

Use a list of pointers to SourceFileInfo structures, not a list of the
structures themselves. This is preparation for a subsequent patch
which makes the data structures less STABS-specific.
This patch introduces a memory leak. If an included file is
referenced only by line entries for functions that LoadFuncSymbols
elected to omit from the func_info list, then its SourceFileInfo
structure is leaked when we destroy the name_to_file map. This leak
is fixed in a subsequent patch by letting the map of files by name own
the file objects.

This upload fixes five issues:
1) Preston's email was hardcoded in the xib :-(
2) Changed from xib to NIB to facilitate Tiger building
3) Changed the logs location to be user specifiable by BreakpadMinidumpLocation
key, or ~/Library/Breakpad/<BREAKPAD_PRODUCT> by default
4) Fixed GTM Defines problem in order to build on Tiger
5) Also set CFBundleIcon in the sender program correctly, and updated plist, and
renamed ReporterIcons to crash_report_sendER.ICNS. However the rietveld upload
script doesn't appear to pick up renamed files correctly, so that file doesn't
show up in the patch upload.
Also various comments were updated for accuracy.

load commands until I found LC_ID_DYLIB. Also modified crash_report to generate version number. Also added suspend/resume capability to exception handler, necessary because exception handling can behave strangely across fork() calls. Also added fix for filtering out functions with no line number information, and for filtering out some multiple inheritance glue the compiler generates.
