* Moved exception_handler_test to the more aptly named ↵hansl@google.com2010-05-1211-399/+793
| | | | | | | | | | | | | | | | 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.

* Breakpad Mac dumper: Clean up XCode project file.jimblandy2010-05-051-102/+70
| | | | | | | | | | | | The XCode project file has become encrufted with duplicate Executable entres and some strange settings. This patch deletes and recreates various entries to make things neat again. It should have no effect on the project's visible behavior. a=jimblandy, r=thestig git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@591 4c0a9323-5329-0410-9bdc-e9ce6186880e

| | | | | | | | | | | | | | | | | | | | 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. a=jimblandy, r=mark git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@590 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad Mac Dumper: Fix compilation warnings on OS X 10.6jimblandy2010-05-054-30/+82
| | | | | | | | | | | | | | | | | 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. a=jimblandy, r=mark git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@589 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad symbol dumper: Promise that Module::SetLoadAddress can be called at ↵jimblandy2010-05-052-5/+13
| | | | | | | | | | | | | | | | | | 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. a=jimblandy, r=thestig git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@588 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad Linux dumper: Handle STABS-in-symbol-table, and line number records ↵jimblandy2010-05-054-21/+152
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. a=jimblandy, r=mark git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@587 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad STABS parser: Use a test fixture in StabsReader unit tests.jimblandy2010-05-051-56/+42
| | | | | | | | | | This patch factors out some of the common code in the StabsReader unit tests into a fixture class. Pretty mechanical. a=jimblandy, r=thestig git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@586 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad STABS reader: Properly compute function end addresses.jimblandy2010-05-053-7/+72
| | | | | | | | | | | | | 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. a=jimblandy, r=thestig git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@585 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad Linux dumper: Rename DumpStabsHandler to StabsToModule.jimblandy2010-05-055-52/+53
| | | | | | | | | | | | | | | 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. a=jimblandy, r=thestig git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@584 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad Linux dumper: Make StabsReader independent of endianness and word size.jimblandy2010-05-0512-595/+446
| | | | | | | | | | | | | | | | | | | | | | | | 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. a=jimblandy, r=thestig git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@583 4c0a9323-5329-0410-9bdc-e9ce6186880e

* Breakpad Linux Dumper: Have DumpStabsHandler free accumulated functions if ↵jimblandy2010-04-282-0/+10
| | | | | | | | | | | | | | | | | | | | | | | 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. a=jimblandy, r=thestig git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@576 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad Dumper: Move CFI register names to DwarfCFIToModule class.jimblandy2010-04-284-46/+110
| | | | | | | | | | | | | | | | | | 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. a=jimblandy, r=thestig git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@575 4c0a9323-5329-0410-9bdc-e9ce6186880e

* Breakpad Linux Dumper: Disable warnings about unpaired functions and lines ↵jimblandy2010-04-053-1/+82
| | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | 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. a=jimblandy, r=nealsid,dmuir git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@563 4c0a9323-5329-0410-9bdc-e9ce6186880e

* Breakpad DWARF parser: correct comments regarding dynamic_cast.jimblandy2010-03-301-7/+14
| | | | | | | | | | | | | | | | 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. a=jimblandy, r=mmentovai git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@561 4c0a9323-5329-0410-9bdc-e9ce6186880e

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.

* Breakpad: Support DWARF CFI-driven stack walking on ARM.jimblandy2010-03-169-34/+782
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch allows the Breakpad minidump processor to use data from STACK CFI records to generate stack traces for the ARM processor. In the symbol dumper, we need a table mapping DWARF CFI register numbers to their names: STACK CFI records refer to registers by name. 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. a=jimblandy, r=mmentovai git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@553 4c0a9323-5329-0410-9bdc-e9ce6186880e
