* Breakpad Linux Dumper: Fix up comments in google_breakpad::Module interface.jimblandy2009-12-231-7/+7

* Issue 49003: Breakpad Linux Dumper: Add unit tests for STABS dumper.jimblandy2009-12-231-0/+175
| | | | | | | | | | | | 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. So now the whole pathway has coverage. a=jimblandy, r=nealsid git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@467 4c0a9323-5329-0410-9bdc-e9ce6186880e

* Linux dumper: Add unit tests for google_breakpad::StabsReader.jimblandy@gmail.com2009-12-156-0/+573
| | | | | | | | | | | | | | | | | | | | | | 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

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

| | | | | | | | | | | | | | | | | | | | | | | 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
* Linux dumper: Don't switch to wrong source file when starting new function.jimblandy@gmail.com2009-08-051-6/+11
| | | | | | | | | | | | | | | | 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. a=jimblandy r=nealsid git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@373 4c0a9323-5329-0410-9bdc-e9ce6186880e

* Linux dumper: Let LineInfo structures point directly to their SourceLineInfo ↵jimblandy@gmail.com2009-08-051-141/+147
| | | | | | | | | | | | | | | | | | | | | 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. a=jimblandy r=nealsid git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@371 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Linux dumper: Don't record file boundary addresses as null-name ↵jimblandy@gmail.com2009-07-301-17/+35
| | | | | | | | | | | | | | | | | | | | | | | | 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. a=jimblandy r=nealsid git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@369 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Linux dumper: Use pointers to SourceFileInfo structures.jimblandy@gmail.com2009-07-301-29/+38
| | | | | | | | | | | | | | | | | | | 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. a=jimblandy r=nealsid git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@368 4c0a9323-5329-0410-9bdc-e9ce6186880e
