mark@chromium.org 615d2c0d6d Separate the "hello" message from the parameter messages in
Inspector::ReadMessages as was done before r627. The "hello" message contains
the parameter count and is referenced while the message reader loops through
parameter messages. Prior to r627, both messages were named |message|, which
was confusing, probably caused a compiler warning, and apparently provided the
motivation to share them. This caused the crash inspector to fail to properly
collect the parameters. The common failure mode (although others are possible)
was for the inspector to attempt tor read more parameter messages than were
available, resulting in an IPC timeout and inspector death. No crash report
would be written, and the application expecting its crash to be inspected
would time out waiting for a response from the inspector and then _exit. This
is effectively a failure to properly handle crashes.

The inner message is reintroduced, and named parameter_message for
disambiguation.

jimblandy 786275e719 Breakpad Linux/Mac symbol dumper: Share duplicate strings that arise in DWARF data.
This patch avoids allocating many copies of identical strings appearing in
debugging information. Without this patch, running dump_syms on Mozilla's
libxul.so (with 173MiB of debugging information) has a peak resident set of
around 450MiB. With this patch, the peak is around 365MiB.

jimblandy c5f5e0ae65 Breakpad Linux dumper: Don't map file into memory a second time just to compute file ID
At present, the Linux symbol dumper maps the ELF file into memory to
examine the debugging information it contains, but then also calls
google_breakpad::FileID::ElfFileIdentifier, which maps the ELF file into
memory again. Some of our object files are large; Mozilla's libxul.so is
1.1GiB. Trying to map such files twice can interfere with tools like
valgrind that map themselves into high addresses (in an attempt to stay out
of the way of ordinary programs).

The FileID class has another method, ElfFileIdentifierFromMappedFile, that
operates on an already-loaded image of the file; use that instead.

This patch avoids unnecessary use of the <cfoo> headers in files that don't
actually use the identifiers they declare in the std:: namespace.

It also changes some files to better conform with the "Names and Order of

ted.mielczarek 6869f2e1b3 Breakpad DWARF CFI parser: Use the proper type for offsets in CallFrameInfo::Rule subclasses.
The subclasses of CallFrameInfo::Rule store the rule currently in
force for recovering a register or computing the canonical frame
address. Their sole responsibility is to accurately convey rules from
the parser, which creates them, to a CallFrameInfo::Handler member
function, which consumes them. So, the types of their data members
should match those of the corresponding arguments of the corresponding
Handler member function.

CallFrameInfo::OffsetRule and CallFrameInfo::ValOffsetRule use an
'int' to store the rule's offset value, but
CallFrameInfo::Handler::OffsetRule and ...::ValOffsetRule expect a
'long'.  On ABIs where 'long' is larger than 'int', this can cause
values to be truncated or sign-extended unexpectedly.

This patch changes those members to 'long'.

Fortunately, offsets appearing in real DWARF call frame information
never even come close to the limits of a 32-bit int, so this bug is
unlikely to cause any practical problems.

ted.mielczarek 1adc07f0ff Breakpad Mac symbol dumper: Unify with Linux dumper; support DWARF CFI.
This patch rewrites the Mac symbol dumper to use the same set of classes
the Linux dumper does for reading debugging information from various
sources, consolidating them into a single table, and writing that out as a
Breakpad symbol file.

In the process, it also adds support for dumping DWARF call frame
information and .eh_frame exception-handling information as Breakpad 'STACK
CFI' records. This allows the Breakpad processor to generate stack traces
from code compiled with -fomit-frame-pointer.

The patch also replaces the DumpSymbols Objective C++ class with
google_breakpad::DumpSymbols, a plain C++ class. The code still uses some
Objective C++ to use the Foundation facilities for dealing with file names
in a file-system-independent fashion, and for examining the contents of
.dSYM bundles.

Since the code has been entirely rewritten, I have changed the author
lines.

look for line number information under both names.

ted.mielczarek 75ce593891 Breakpad Mac dumper: Change the dumper to be more C++-ish.
Instead of using bzero in main, use constructors to initialize the
Options structure.

Use C++ bool, not Objective-C BOOL.

Use a const NXArchInfo * to represent the architecture name, so that we can
use the NXGetLocalArchInfo, NXGetArchInfoFromName, etc. to handle things.

Delete the 'uuidStr' member; it is unused.

Leave Options::srcPath as an NSString, so that we can continue to use the
filesystem path abstraction methods provided by the Foundation framework.

ted.mielczarek 35c41e00ee Breakpad Mac symbol dumper: Add new Mach-O reader class.
This patch adds files defining new classes in the google_breakpad::Mach_O
namespace for parsing fat binaries and Mach-O files. These are used in the
new dumper to handle STABS debugging information, DWARF call frame
information, and .eh_frame exception handling stack walking information.

These new classes are independent of endianness and word size, and
therefore can be used on binaries of all the relevant architectures: x86,
x86_64, ppc, and ARM.

The patch adds a complete set of unit tests for the new classes.

hansl@google.com 8cf0a52bec Moved exception_handler_test to the more aptly named 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.

jimblandy 073a7f6695 Breakpad unit tests: Add support for clipped-size null-terminated strings
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.

jimblandy 52a508dfe2 Breakpad Mac Dumper: Fix compilation warnings on OS X 10.6
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.

jimblandy 25b512d64d Breakpad symbol dumper: Promise that Module::SetLoadAddress can be called at 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.

jimblandy 775c6f7640 Breakpad Linux dumper: Handle STABS-in-symbol-table, and line number records 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.

jimblandy b0ec96cee2 Breakpad Linux dumper: Make StabsReader independent of endianness and word size.
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.

jimblandy 56e7a3c65d Breakpad Linux Dumper: Have DumpStabsHandler free accumulated functions if 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.

so there's no reason those tables shouldn't be shared between the Linux and

they the Mac dumper can use them when it is changed to use
DwarfCFIToModule.

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.

In the processor, we expand StackwalkerARM::GetCallerFrame to see if
there are STACK CFI records covering the callee, and then use those to
recover the caller's register values.

There's no good reason the ARM walker couldn't use the SimpleCFIWalker
interface declared in cfi_frame_info.h. Unfortunately, that interface
assumes that one can map register names to member pointers of the raw
context type, while MDRawContextARM uses an array to hold the
registers' values: C++ pointer-to-member types can't refer to elements
of member arrays. So we have to write out SimpleCFIWalker::FindCallerRegisters
in StackwalkerARM::GetCallerFrame.

We define enum MDARMRegisterNumbers in minidump_cpu_arm.h, for
convenience in referring to certain ARM registers with dedicated
purposes, like the stack pointer and the PC.

We define validity flags in StackFrameARM for all the registers, since
CFI could theoretically recover any of them. In the same vein, we
expand minidump_stackwalk.cc to print the values of all valid
callee-saves registers in the context --- and use the proper names for
special-purpose registers.

We provide unit tests that give full code and branch coverage (with
minor exceptions). We add a testing interface to StackwalkerARM that
allows us to create context frames that lack some register values.

jimblandy a76aaa1442 Breakpad Linux dumper: Parse the .eh_frame section.
Extend google_breakpad::CFISection with the ability to produce
.eh_frame data. Entry headers have a different format, and pointers
can be encoded in new and fascinating ways.

Extend dwarf2reader::CallFrameInfo to be able to parse either DWARF
CFI or .eh_frame data, as determined by an argument to the
constructor. Cope with variations in header formats, encoded pointers,
and additional data in 'z' augmentation data blocks. Extend the unit
tests appropriately.

Extend dump_syms to look for a .eh_frame section, and if it is
present, find the necessary base addresess and parse its contents.

There's no need for DwarfCFIToModule to check the version numbers; if
CallFrameInfo can parse it, DwarfCFIToModule should be able to handle
it. Adjust tests accordingly.

jimblandy 841ad48a37 Breakpad Linux symbol dumper: Handle programs linked with --gc-sections.
As explained in the code:

Given the right options, the GNU toolchain will omit unreferenced
functions from the final executable. Unfortunately, when it does so,
it does not remove the associated portions of the line number program;
instead, it lets the symbol references in the DW_LNE_set_address
instructions pointing to the now-deleted code resolve to zero. Given
this input, the DWARF line parser will call AddLine with a series of
lines starting at address zero.

Rather than collecting series of lines describing code that is not
there, we should drop them. Since the linker doesn't explicitly
distinguish references to dropped sections from genuine references to
zero, we must use a heuristic. We have chosen:

 - If a line starts at address zero, omit it. (On the platforms
   breakpad targets, it is extremely unlikely that there will be code
   at address zero.)

 - If a line starts immediately after an omitted line, omit it too.

Any DIE with an DW_AT_inline attribute can be cited by

FindSectionByName will return the first section whose name starts with

For example, if we search for the section named ".eh_frame", we may
get the section named ".eh_frame_hdr".

Instead, check that the section name section has enough space to store
the complete name with its terminating '\0', and then use strcmp,
which will never examine more than strlen(NAME) + 1 bytes from the
section name section, regardless of its contents, and will require the
terminating '\0' to match as well.

don't think putting an author notice on the files is a good idea; it's
odd to have the original author retain prominence even if the file has
been heavily edited by others; the version control system answers this
question more accurately. This is only for Style Guide compliance. The
Apache group decided to discourage author annotations, partially for
these reasons:

frame does have windows unwinding information.

This is not user-visible behavior, so it doesn't matter, but it is a

expect it.

jimblandy 03ebc1d245 Breakpad processor: Fix function and public symbol lookup.
In r480, I botched the change to make the comparisons that decide
whether an address falls within a function's range safe from overflow.
The original code said:

  address >= function_base && address < function_base + function_size

which is fine unless the function abuts the end of the address space,
in which case the addition overflows and you get a false negative.

My change subtracted function_size from both sides of the latter
comparison, which is meaning-preserving in true math, and gets you:

  address >= function_base && address - function_size < function_base

This not only reads strangely, but also still overflows if
function_size is greater than address. That's rare, but I've added a
case to the unit tests that checks it.

My intent had been to replace the addition which could overflow with a
subtraction that was known not to overflow, namely:

  address >= function_base && address - function_base < function_size

This is equivalent to the original in true math, and because of the
first comparison, we know the subtraction won't underflow in MemAddr
math.

The patch includes similar fixes to the public symbol lookup code, and
to FindWindowsFrameInfo, which was the only other function affected by
r480.

jimblandy 057aa1f617 Breakpad Linux Dumper: Add DWARF support.
This adds DWARF support to the Breakpad Linux dumper. This is
implemented as two handler classes: google_breakpad::DwarfCUToModule
accepts data from dwarf2reader::CompilationUnit, and
google_breakpad::DwarfLineToModule accepts data from a
dwarf2reader::LineInfo, each populating a google_breakpad::Module with
the results. Behaviors specific to particular source languages are
handled by instances of a new class, google_breakpad::Language.

An input executable may contain both STABS and DWARF debugging
information: the dumper automatically recognizes what sorts of
information are available, and integrates the data into a single
output file.

All classes have unit tests, providing line and branch coverage of all
interesting code. Unit tests are written using the Google C++ Testing
Framework, and the Google C++ Mocking Framework where appropriate.

jimblandy bc64ee962f Breakpad DWARF Parser: Improved DWARF-processing interface.
dwarf2reader::CompilationUnit is a simple and direct parser for DWARF
data, but its handler interface is not convenient to use. In
particular, the same handler object receives data about all DIEs
processed. One can't use distinct classes to separate the information
needed to handle different kinds of data.

This patch defines a new adapter type, dwarf2reader::DIEHandler, which
implements the existing DWARF parser's handler interface, given a
handler written to a more comfortable, object-orient interface. The
comments in dwarf2diehandler.h provide more detail.

jimblandy 2684b4dc19 Breakpad processor: Don't pass Windows stack walking information to all walkers.
At the moment, the StackWalker GetCallerFrame member function expects
a vector of WindowsFrameInfo structures, even though WindowsFrameInfo
is only used or useful on one one implementation (StackWalkerX86).

This patch changes StackWalker::GetCallerFrame to no longer expect the
WindowsFrameInfo structures, and changes all implementations to match.

In particular, StackWalkerX86 is changed to find the WindowsFrameInfo
data itself, and store a pointer to whatever it got in the StackFrame
object itself (which is really a StackFrameX86).

To allow GetCallerFrame implementations to look up stack walking data,
StackWalker::resolver_ needs to be made protected, not private.

jimblandy 5251e64f48 Breakpad Linux dumper: STABS reader incorrectly assumes a single compilation unit
The stabs reading code in google-breakpad incorrectly assumes that the
stabs data is a single compilation unit. Specifically, it ignores
N_UNDF stabs and assumes that all string indices are relative to the
beginning of the .stabstr section.

This is true when linking with the GNU linker by default, because the
GNU linker optimizes stabs debug info. The gold linker does not do
this optimization. It can be disabled when using the GNU linker with
the --traditional-format command line option.

For more details of the problem, see:

http://sourceware.org/bugzilla/show_bug.cgi?id=10338

jimblandy e9faf54828 Issue 49013: Breakpad Processor: Use a separate API to retrieve Windows stack debugging info.
At the moment, FillSourceLineInfo returns Windows DIA-based stack
walking data. In addition to being ugly, this makes it difficult to
provide access to DWARF CFI-based stack walking data in a symmetrical

This patch changes FillSourceLineInfo to do the single job its name
suggests, and adds a second member function to
SourceLineResolverInterface to retrieve Windows DIA stack walking
information. A sibling member function will provide access to DWARF
CFI stack walking data.

jimblandy@gmail.com 7a77f45f79 Breakpad DWARF parser: Fix up documentation for DWARF reader classes.
Fix typos.

For CompilationUnit::Start, I was confused by the '-' in the original
comment, taking it for a parenthetic clause marker, assuming an
implicit "of the next compilation unit" at the end of the sentence.

The comments should refer to the ".debug_info" section, not the
"debug_info" section. The latter is not the section name actually used
on any system (ELF or Mach-O), and the former is the name prescribed
by the DWARF spec.

Some of the comments for ProcessAttribute* member functions claim that
OFFSET is from the start of the compilation unit, but that's not so:
the code has always passed an offset relative to the start of the
.debug_info section.
