Greg Clayton c51d70d9d5 Show source by default for the first 4 frames of the crash thread. Also added options to allow showing source for all frames (--source-frames=NFRAMES) and for all threads (--source-all).

Greg Clayton 563d03934c Added the ability to see source context with each frame in the "crashlog" command with the "--source-context" (-C for short to match grep) option.
Also made the symbolication of the crash logs more efficient when using the "--crashed-only" ("-c") option where only the crashed thread is symbolicated. We now only download the images for the frames in the crashed thread.

Greg Clayton 9407302d37 Make const result value objects able to return dynamic types.
Modified the heap.py to be able to correctly indentify the exact ivar for the "ptr_refs" command no matter how deep the ivar is in a class hierarchy. Also fixed the ability for the heap command to symbolicate the stack backtrace when MallocStackLogging is set in the environment and the "--stack" option was specified.

Greg Clayton f7ab038ada Make the interactive command interpreter build into the "crashlog" command work correctly when run inside LLDB. Before this fix the "cmd.Cmd" object was trying to read from stdin itself and it was competing without command interpreter for the bytes.

Greg Clayton a7fb1dcd4b Listen to the "--verbose" flag when running "crashlog" and if verbose is enabled, then dump full paths to source files and modules.
Changed much of the output that was coming out with "--verbose" over to use the new "--debug" flag.

Greg Clayton f47b2c26bb Added a "save_crashlog" command to the lldb.macosx.crashlog package that allow you to dump your current process state out to a crash log file. This will dump all of the target module information with all load addresses, UUID values, and shared library paths, as well as all thread stacks and the crash log header. This will make it easy for us to save the current state of a process and then reload it later into LLDB.

Greg Clayton f51a23fb6f Cleaned up some stuff in symbolication where we can now lazily get images when symbolicating after loading a crash log file.
Added colorization to the gdbremote.py output and also added the ability to symbolicate the addresses in registers.

Greg Clayton 8ebb9a8564 Added the ability to disassembly GDB remote packets with the python file. This will make it easier to symbolicate the packet log output since we can use the lldb.utils.symbolication package module to symbolicate register values.

Greg Clayton 60bb58f669 Modified the symbolication.Image object to store its uuid as a uuid.UUID object and made an accessor for getting a normalized UUID value out of the image object.
Modified the crashlog darwin module to always create a uuid.UUID object when making the symbolication.Image objects. Also modified it to handle some more types of crash log files and improved the register reading for thread registers of crashed threads.

Greg Clayton c8f73d7b96 Added an interactive mode to the "crashlog" command so that we can look at multiple crash logs at once and do some data mining. Added an interactive command prompt that allows you to do:
% PYTHONPATH=./build/Debug/LLDB.framework/Resources/Python ; ./build/Debug//LLDB.framework/Resources/Python/lldb/macosx/crashlog.py -i ~/Downloads/crashes2/*.crash ) 

then you get an interactive prompt where you can search for data within all crash logs. For example you can do:

% list

which will list all crash logs

And you can search for all images given an image basename, or full path:

% image LLDB
% image /Applications/Xcode.app/Contents/SharedFrameworks/LLDB.framework/Versions/A/LLDB
% image LLDB.framework

Which would all produce an output listing like:

Greg Clayton d712ef0fd7 Remove the "-x" from the finish-swig-Python-LLDB.sh shell options so it doesn't print out all of the commands when executing the shell script.
Cleaned up the lldb.utils.symbolication, lldb.macosx.heap and lldb.macosx.crashlog. The lldb.macosx.heap can now build a dylib for the current triple into a temp directory and use it from there.

2012-04-06 21:04:20 +00:00
Sean Callanan ceabd2d712 Updated the disassembler stress tester with two
new features:

(1) it outputs the instruction currently being
    tested to a log file, if a path is provided

(2) if instructed, it prints the time remaining
    in the exhaustive test

llvm-svn: 154205
2012-04-06 20:53:23 +00:00
Sean Callanan d181730aa5 Added a stress-tester for LLDB's disassembler.
Right now it only works on Mac OS X, but other
platforms would just need to add their own
implementation of AddLLDBToSysPathOn*().

The stress-tester has two modes:

Used with --bytes N --random, the stress-tester
generates random instructions of length N and
runs them through the disassembler.  This is
suitable for architectures like Intel where it
is combinatorially infeasible to run through the
entire space of possible instructions.

Used with --bytes N and no arguments (or --start
S --stride T), the stress-tester tests the
disassembler with a monotonically increasing
sequence of instructions.

The --start and --stride arguments are intended
for use in multiprocessing environments.  Give
each core an ID from 0 .. T-1, pass the ID in as
the --start, and use T as the stride, and you
can launch one copy of the stress-tester on each
core you have available.

2012-03-23 00:01:02 +00:00
Greg Clayton 0f729e9b38 Added python script that implements a "parse_log_file" command in LLDB which can
parse the output from "log enable --timestamp ...." and converts it to be relative
to the first timestamp and shows the time deltas between log lines. This can also
be used as a stand along script outside of lldb:

./delta.py log.txt

Greg Clayton 2b1bc868a0 Added a fix to the crash log script that allows you to locate and load a binary from any location and _then_ do the symbolication. Something like:
(lldb) file /path/to/file.so
(lldb) crashlog crash.log
....

Then if the file.so has already been loaded it will use the one that is already in LLDB without trying to match up the paths.

Greg Clayton 0a94b6614a Added a new lldb.SBValue helper module that has two classes:
sbvalue.value (<SBValue>)
sbvalue.variable (<SBValue>)

Initialize both with a lldb.SBValue

sbvalue.value() make all sorts of convenience properties. Type "help(sbvalue.value)" 
in the embedded python interpreter to see what is available.

sbvalue.variable() wraps a lldb.SBValue and allows you to play with your variable just
as you would expect:

pt = sbvalue.variable (lldb.frame.FindVariable("pt"))

print pt.x
print py.y

argv = sbvalue.variable (lldb.frame.FindVariable("argv"))
print argv[0]

Member access and array acccess is all taken care of!

Greg Clayton e284163990 Added a 'gdbremote' python module that adds two commands: start_gdb_log and end_gdb_log.
When this is imported into your lldb using the "command script import /path/to/gdbremote.py"
these new commands are available within LLDB. 'start_gdb_log' will enable logging with 
timestamps for GDB remote packets, and 'stop_gdb_log' will then dump the details and
also a lot of packet timing data. This allows us to accurately track what packets are
taking up the most time when debugging (when using the ProcessGDBRemote debugging plug-in).

Also udpated the comments at the top of the cmdtemplate.py to show how to correctly import
the module from within LLDB.

Greg Clayton bc48f32d0a Added options to specify how many instructions before and after the frame
PC to disassemble. Users can also specify the frame depth to disassemble to

Greg Clayton 53b43b0798 Use the "shlex" module to parse the command line that was passed down into
python so that single and double quotes and other standard shell like argument
parsing happens as expected before passing stuff along to option parsing.

Also handle exceptions so that we don't accidentally exit lldb if an uncaught
exception occurs.

Greg Clayton 5c0f483ec1 Fixed it so the "--help" option works for the crashlog command. Corrected and
filled out the command help and removed unused options.

Updated the command to have a "--load-all" option that will cause the target
that gets created to locate and load all images specified in the Binary Images
section of the crash log to allow for complete program state to be matched
to that of the crash log, not just the images that were in the stack frames
(the default).

Greg Clayton 42a6eb7195 Make the script work again from the command line as long as the PYTHONPATH
environment variable it set to include a path to lldb.py.

Also fixed the case where the executable can't be located and doesn't match
what is installed on the current system. It will still symbolicate the other
frames, and will just show what was originally in the crash log file.

Also removed the --crash-log option so the arguments to the "crashlog"
command are one or more paths to crash logs.

Fixed the script to "auto-install" itself when loaded from the embedded
script interpreter. Now you only need to import the module and the
command is ready for use.

llvm-svn: 148561
2012-01-20 19:25:32 +00:00
Greg Clayton 3d8d3db34e More fixed to verify if a file in the crash log is installed in the current

and not at all.

llvm-svn: 148534
2012-01-20 06:12:47 +00:00
Greg Clayton a32bfbeeda Improved the regular expressions to handle "+" characters being at the front
of the identifier name in the binary images section. Improved the regular
expression for the frames.

Added a new file "crashlog.lldb" which can be sourced with "command source"
that will import the module and set itself up to be used as a command.

llvm-svn: 148529
2012-01-20 03:32:35 +00:00
Greg Clayton aa9d02b17c Modified the symbolicate-crash.py so it can be imported into python as a
module (you can't import a module with a '-' in it) and also added a
Symbolcate(...) top level function so it can be imported and used as an
LLDB command.

Then you can import the module and map a "crashlog" command (for darwin
use only currently) to the python function "crashlog.Symbolicate":

(lldb) script import crashlog
(lldb) command script add -f crashlog.Symbolicate crashlog

Then use it to symbolicate:

(lldb) crashlog --crash-log /path/to/foo.crash

The crash log will then get symbolicated and inline frames will be added to
the crash log and the frames will be displayed. The crash log currently will
only try and fetch and setup the target images requires in order to do the
symbolication.

This will need to be iterated upon, but it is getting close to being useful
so I am going to check this in.

Greg Clayton 1ed54f50c5 Cleaned up the the code that figures out the inlined stack frames given a
symbol context that represents an inlined function. This function has been
renamed internally to:

bool
SymbolContext::GetParentOfInlinedScope (const Address &curr_frame_pc, 
                                        SymbolContext &next_frame_sc, 
                                        Address &next_frame_pc) const;
                                        
And externally to:

SBSymbolContext
SBSymbolContext::GetParentOfInlinedScope (const SBAddress &curr_frame_pc, 
                                          SBAddress &parent_frame_addr) const;

The correct blocks are now correctly calculated.

Switched the stack backtracing engine (in StackFrameList) and the address
context printing over to using the internal SymbolContext::GetParentOfInlinedScope(...) 
so all inlined callstacks will match exactly.

llvm-svn: 140910

Greg Clayton 2f9ca7b1f5 Added an example that symbolicates symbol information. This file
is mostly geared towards darwin crash logs at the moment, though
it could be made more generic with a few tweaks. 

The symbolicate-crash.py script will make a target given a crash log
and then symbolicate all frames and expand any frames that had inlined
functions in them to show all frames back to the concrete function. It
will also disassemble around the crash site.

Greg Clayton 05faeb7135 Cleaned up the SWIG stuff so all includes happen as they should, no pulling
tricks to get types to resolve. I did this by correctly including the correct
files: stdint.h and all lldb-*.h files first before including the API files.
This allowed me to remove all of the hacks that were in the lldb.swig file
and it also allows all of the #defines in lldb-defines.h and enumerations
in lldb-enumerations.h to appear in the lldb.py module. This will make the
python script code a lot more readable.

Cleaned up the "process launch" command to not execute a "process continue"
command, it now just does what it should have with the internal API calls
instead of executing another command line command.

Made the lldb_private::Process set the state to launching and attaching if

Greg Clayton 5d5028b54e Added the first of hopefully many python example scripts that show how to
use the python API that is exposed through SWIG to do some cool stuff.

Also fixed synchronous debugging so that all process control APIs exposed
through the python API will now wait for the process to stop if you set
the async mode to false (see disasm.py).
