* Add some unit tests for Linux WriteSymbolFileted.mielczarek2011-07-061-1/+2
| | | | | | | | | | | This patch adds synth_elf::{StringTable,SymbolTable,ELF} classes to produce in-memory ELF files to properly test the Linux symbol dumping code. It also uses those classes to add some basic tests for the WriteSymbolFile function.

* Breakpad: Avoid using the C++ <cfoo> headers.ted.mielczarek2010-06-251-1/+1
| | | | | | | | | | | | 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 Includes" rules in the Google C++ Style Guide.

| | | | | | | | The dwarf_cu_to_module_unittest and bytereader_unittest test executables include object files from which they use no code. A=jimb R=thestig git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@617 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad Linux dumper: Rename DumpStabsHandler to StabsToModule.jimblandy2010-05-051-18/+19
| | | | | | | | | | | | | | | 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.jimblandy2010-05-051-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | 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 symbol dumper: Define the ByteBuffer and ByteCursor classes.jimblandy2010-05-051-0/+19

| | | | | | | | | | | | | | src/common. The google_breakpad::TestAssembler classes are used in both the processor's and the Linux dumper's test suites, and will soon be used in the Mac dumper's tests as well. This patch moves their source files from src/processor to src/common. a=jimblandy, r=thestig git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@574 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad symbol dumper: Move Linux dumping classes into src/common.jimblandy2010-04-051-3/+5
| | | | | | | | | | | The Linux symbol dumper's classes are reasonably portable, and should be usable for the Mac dumper as well. Move them to src/common, along with their unit tests. Update #include directives and Makefile. a=jimblandy, r=nealsid git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@567 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad Linux dumper: Generate make dependencies on header files automatically.jimblandy2010-04-011-5/+9
| | | | | | | | | | | | | 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: Add support for parsing .eh_frame encoded pointers.jimblandy2010-03-161-0/+21
| | | | | | | | | | | | The Linux C++ exception handling data format (.eh_frame) can specify a number of different encodings for the addresses it contains. This patch extends dwarf2reader::ByteReader to read pointers encoded in these ways. a=jimblandy, r=nealsid git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@551 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad Linux dumper: Add support for dumping DWARF CFI as STACK CFI records.jimblandy2010-03-161-1/+54
| | | | | | | | | | | | | | | | | | | | | | | Define a new DWARF parser class, dwarf2reader::CallFrameInfo. Extend google_breakpad::Module to store and write out 'STACK CFI' records. Define a new google_breakpad::DwarfCFIToModule class, to accept DWARF CFI data from the parser and populate a Module with the equivalent STACK CFI records. Extend the Linux symbol dumping tool, dump_syms, to use dwarf2reader::CallFrameInfo, google_breakpad::DwarfCFIToModule, and google_breakpad::Module to extract DWARF CFI from the executable or shared library files and write it to the Breakpad symbol file. Define CFISection, a new class derived from TestAssembler::Section, for use in creating DWARF CFI data for test cases. a=jimblandy, r=nealsid git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@550 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Linux DWARF reader: Follow DW_AT_abstract_origin links to find function names.jimblandy2010-02-101-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | Without this patch, debugging information like the following will produce FUNC records with no names, because the dumper (correctly) ignores the DW_TAG_subprogram DIEs that lack DW_AT_low_pc/DW_AT_high_pc attributes, but won't follow the DW_AT_abstract_origin link from the DIE that does have code addresses to find its name. <1><168>: Abbrev Number: 5 (DW_TAG_class_type) <169> DW_AT_name : Foo <2><183>: Abbrev Number: 7 (DW_TAG_subprogram) <185> DW_AT_name : Foo <18b> DW_AT_declaration : 1 <1><1b7>: Abbrev Number: 12 (DW_TAG_subprogram) <1b8> DW_AT_specification: <0x183> <1bc> DW_AT_inline : 2 (declared as inline but ignored) <1><1dc>: Abbrev Number: 16 (DW_TAG_subprogram) <1dd> DW_AT_abstract_origin: <0x1b7> <1e1> DW_AT_low_pc : 0x8048578 <1e5> DW_AT_high_pc : 0x8048588 a=dmuir, r=jimblandy git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@520 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad Linux dumper: Don't be silly about global functions.jimblandy2010-02-091-4/+3
| | | | | | | | | | | | Yes, classes are useful. But that doesn't mean that every function has to gratuitously become a member function. The Google C++ Style Guide does not require this silliness, since the function is in the google_breakpad namespace anyway. a=jimblandy, r=nealsid git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@519 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad Linux symbol dumper: Don't disable asserts.jimblandy2010-01-271-1/+0
| | | | | | | | | | | Having NDEBUG be the default has wasted my time more often than I'm proud to admit. There are no expensive asserts in the Linux symbol dumper. a=jimblandy, r=nealsid git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@502 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad Linux Dumper: Add DWARF support.jimblandy2010-01-231-1/+55
| | | | | | | | | | | | | | | | | | | | | | | | 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.jimblandy2010-01-231-0/+22
| | | | | | | | | | | | | | | | | | 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

* Issue 49003: Breakpad Linux Dumper: Add unit tests for STABS dumper.jimblandy2009-12-231-0/+18
| | | | | | | | | | | | Previous patches added unit tests for the STABS parser and the Breakpad symbol file writer; this adds unit tests for the "dumper" class that sits between them, receiving data from the parser and handing it to the writer.

* Linux dumper: Add unit tests for google_breakpad::StabsReader.jimblandy@gmail.com2009-12-151-0/+34
| | | | | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | Use GNU Make features to make the dumper, unit tests, and maintenance targets more independent, so I get fewer conflicts as I work on different parts of the patch series. In particular: - Provide targets to run tests and produce test coverage reports. - Gather C and C++ build rules in one place. - Avoid variables that list object files, as pattern rules can compute these values directly from the dependencies. - Use VPATH to find sources in other directories. a=jimb, r=nealsid git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@441 4c0a9323-5329-0410-9bdc-e9ce6186880e

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
