* Breakpad Linux dumper: Add file comments as required by the style guide.jimblandy2010-02-0923-17/+116
| | | | | | | | | | | | | | | | | | | | | | This also includes some comments I promised Cary Coutant I'd write about the appropriateness of processing attributes in EndAttributes calls. The Google C++ Style Guide requires each file to have an author notice and a comment explaining the file's general purpose. For the record, I 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: http://mail-archives.apache.org/mod_mbox/jakarta-jmeter-dev/200402.mbox/%3C4039F65E.7020406@atg.com%3E a=jimblandy, r=nealsid git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@518 4c0a9323-5329-0410-9bdc-e9ce6186880e

* Breakpad Linux dumper: Recognize more processor architectures.jimblandy2010-02-021-12/+35
| | | | | | | | | | | | | | This extends the ElfArchitecture function to recognize the architectures it seemed to me that breakpad was most likely to see.

| | | | | | | | | | | This patch moves the ReadInitialFunction from dwarf2reader.cc, where it was a static function, to being a member function of google_breakpad::ByteReader. a=jimblandy, r=nealsid git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@504 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad Linux Dumper: Add DWARF support.jimblandy2010-01-2310-27/+3941
| | | | | | | | | | | | | | | | | | | | | | | | 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. a=jimblandy, r=ccoutant git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@497 4c0a9323-5329-0410-9bdc-e9ce6186880e

* Breakpad DWARF Parser: Improved DWARF-processing interface.jimblandy2010-01-233-0/+1084
| | | | | | | | | | | | | | | | | | 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. a=jimblandy, r=ccoutant git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@495 4c0a9323-5329-0410-9bdc-e9ce6186880e

| | | | | | | | | | | | | | | | | | | | length. Breakpad's DWARF line number info parser provides a code address, file, and line number for each code/source pairing, but doesn't provide the length of the machine code. This makes that change, as discussed in the following thread: http://groups.google.com/group/google-breakpad-dev/browse_thread/thread/ed8d2fde79319368p This patch also makes the corresponding changes to the functioninfo.cc module, used by the Mac dumper.

* Breakpad Linux dumper: STABS reader incorrectly assumes a single compilation ↵jimblandy2010-01-143-35/+194
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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 http://code.google.com/p/google-breakpad/issues/detail?id=359 This patch adds unit tests that reproduce the failure, and fixes the stabs parser. a=jimblandy, r=nealsid git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@490 4c0a9323-5329-0410-9bdc-e9ce6186880e

| | | | | | | | | | | | | | | | | | | | | | | 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. a=jimblandy, r=nealsid git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@453 4c0a9323-5329-0410-9bdc-e9ce6186880e

| | | | | | | | | | | | | | | | src/common/dwarf/dwarf2reader.cc uses the old-fashioned <stdio.h> facilities to report errors. Ideally, we would add a 'Warning' message to the handler and make the client responsible for dealing with the errors, but this at least allows us to compile.

* Issue 42002: Breakpad DWARF parser: avoid using <stdint.h> typejimblandy@gmail.com2009-12-153-3/+11
| | | | | | | | | | | | | | | | | | | | | It seems that a use of the <stdint.h> type uintptr_t has crept into the DWARF parser. This defines a workaround for the GNU compilers (tested on both Mac and Linux) which will raise an error if it doesn't work. My personal preference would be just to assume that the <stdint.h> header is available and use the standard types everywhere, but 1) that would be a large change, likely to make merges with the other branches of the DWARF parser more difficult, and 2) it would make it quite difficult to build under Microsoft Visual Studio, which doesn't have the <stdint.h> header; Microsoft has said they have no plans to provide it, as they would rather "focus their efforts" on C++ and .NET. a=jimblandy, r=nealsid git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@448 4c0a9323-5329-0410-9bdc-e9ce6186880e

| | | | | | | | | | | | | | | | | | | | | | 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. a=jimblandy, r=nealsid git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@444 4c0a9323-5329-0410-9bdc-e9ce6186880e

| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | 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. a=jimblandy r=nealsid git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@380 4c0a9323-5329-0410-9bdc-e9ce6186880e

| | | | | | | | | | | | | 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. a=jimblandy r=nealsid git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@378 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Linux dumper: Make the 'name' field of FuncInfo a std::string instead of a ↵jimblandy@gmail.com2009-08-051-10/+13
| | | | | | | | | | | | | | | | | | | 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. a=jimblandy r=nealsid git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@375 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Linux dumper: Properly separate function names from STABS type data.jimblandy@gmail.com2009-08-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: ## --- base/libxul.so.syms 2009-07-13 21:46:33.000000000 -0700 ## +++ tip/libxul.so.syms 2009-07-13 21:51:04.000000000 -0700 ## @@ -3907,7 +3907,7 @@ ## FILE 3905 /home/jimb/mc/in/gfx/cairo/libpixman/src/pixman-region.c ## FILE 3906 combine.inc ## FILE 3907 /home/jimb/mc/in/gfx/cairo/libpixman/src/pixman-edge-imp.h ## -FUNC 19898c 54 0 _Z20NS_GetCaseConversionv:F(0,1201)=*(0,1202)=xsnsICaseConvers ## ion ## +FUNC 19898c 54 0 NS_GetCaseConversion() ## 19898c 12 54 1 ## 19899e 9 56 1 ## 1989a7 6 60 1 ## @@ -214776,7 +214776,7 @@ ## 3847c9 9 57 506 ## 3847d2 13 58 506 ## 3847e5 7 59 506 ## -FUNC 387e89 27 0 _ZN20nsGenericHTMLElement11FromContentEP10nsIContent:F(0,8117) ## =*(0,8118)=xsnsGenericHTMLElement ## +FUNC 387e89 27 0 nsGenericHTMLElement::FromContent(nsIContent*) ## 387e89 7 80 2584 ## 387e90 3 80 2584 ## 387e93 e 82 2584 ## @@ -250473,7 +250473,7 @@ ## 3d0d88 7 82 548 ## 3d0d8f 25 84 548 ## 3d0db4 5 85 548 ## -FUNC 3d0e0c 40 0 _ZL21GetEnclosingListFrameP8nsIFrame:f(0,7182)=*(0,7183)=xsnsL ## istControlFrame ## +FUNC 3d0e0c 40 0 GetEnclosingListFrame(nsIFrame*) ## 3d0e0c 5 146 549 ## 3d0e11 3 722 2645 ## 3d0e14 d 146 549 a=jimblandy r=nealsid git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@374 4c0a9323-5329-0410-9bdc-e9ce6186880e
