Greg Clayton fe9d1ee9e4 Added a new python example which installs a command called "shadow".
This shows how to grab individual blocks from stack frames and get only the variables from those blocks. It then will iterate over all of the parent blocks and look for shadowed variables.

Ulrich Weigand 0501eebda6 Miscellaneous fixes for big-endian systems
This patch fixes a bunch of issues that show up on big-endian systems:

- The gnu_libstdcpp.py script doesn't follow the way libstdc++ encodes
  bit vectors: it should identify the enclosing *word* and then access
  the appropriate bit within that word.  Instead, the script simply
  operates on bytes.  This gives the same result on little-endian
  systems, but not on big-endian.

- lldb_private::formatters::WCharSummaryProvider always assumes wchar_t
  is UTF16, even though it could also be UTF8 or UTF32.  This is mostly
  not an issue on little-endian systems, but immediately fails on BE.
  Fixed by checking the size of wchar_t like WCharStringSummaryProvider
  already does.

- ClangASTContext::GetChildCompilerTypeAtIndex uses uint32_t to access
  the virtual base offset stored in the vtable, even though the size
  of this field matches the target pointer size according to the C++
  ABI.  Again, this is mostly not visible on LE, but fails on BE.

- Process::ReadStringFromMemory uses strncmp to search for a terminator
  consisting of multiple zero bytes.  This doesn't work since strncmp
  will stop already at the first zero byte.  Use memcmp instead.

Zachary Turner c07138f6a0 Python 3 - modernize exception catching syntax.
Old-style syntax:  `except Exception, e:`
New-style syntax:  `except Exception as e:`

These two statements are identical, except that the former has
been deprecated for may versions, and was removed in Python 3.

This converts everything to use the new syntax (which also works
in Python 2).  I had to convert unittest2 as well.  What we really
need to do is just delete unittest2, and use unittest instead since
it is a standard module that ships with every Python distribution.
But this is the path of least resistance for now, although at
some point we will really need to do it.

Greg Clayton 424a5dbc73 Added a new API to SBFrame:
lldb::addr_t SBFrame::GetCFA();

This gets the CFA (call frame address) of the frame so it allows us to take an address that is on the stack and figure out which thread it comes from.

Also modified the heap.py module to be able to find out which variable in a frame's stack frame contains an address. This way when ptr_refs finds a match on the stack, it get then report which variable contains the pointer.

llvm-svn: 238393
2015-05-28 03:27:22 +00:00
Greg Clayton 4e1042e1bf Allow expresions to have unique expression prefixes:
expr_options = lldb.SBExpressionOptions()
expr_options.SetPrefix('''
struct Foo {
   int a;
   int b;
   int c;
}
'''
expr_result = frame.EvaluateExpression ("Foo foo = { 1, 2, 3}; foo", expr_options)

This fixed a current issue with ptr_refs, cstr_refs and malloc_info so that they can work. If expressions define their own types and then return expression results that use those types, those types get copied into the target's AST context so they persist and the expression results can be still printed and used in future expressions. Code was added to the expression parser to copy the context in which types are defined if they are used as the expression results. So in the case of types defined by expressions, they get defined in a lldb_expr function and that function and _all_ of its statements get copied. Many types of statements are not supported in this copy (array subscript, lambdas, etc) so this causes expressions to fail as they can't copy the result types. To work around this issue I have added code that allows expressions to specify an expression specific prefix. Then when you evaluate the expression you can pass the "expr_options" and have types that can be correctly copied out into the target. I added this as a way to work around an issue, but I also think it is nice to be allowed to specify an expression prefix that can be reused by many expressions, so this feature is very useful.

Greg Clayton 994ba64756 Played around with TK UI a bit this weekend.
If you "command script import" this file, then you will have two new commands:

(lldb) tk-variables
(lldb) tk-process

Not sure how this will work on all other systems, but on MacOSX, you will get a window with a tree view that allows you to inspect your local variables by expanding variables to see the child values.

The "tk-process" allows you to inspect the currently selected process by expanding the process to see the threads, the threads to see the frames, and the frames to see the variables. Very handy if you want to view variables for all frames simultaneously.

- Added a new "composite" key/value pair that can specify that a register is made up of two or more registers:

Greg Clayton ef8180a3f6 <rdar://problem/14972424>
When debugging with the GDB remote in LLDB, LLDB uses special packets to discover the
registers on the remote server. When those packets aren't supported, LLDB doesn't
know what the registers look like. This checkin implements a setting that can be used
to specify a python file that contains the registers definitions. The setting is:

(lldb) settings set plugin.process.gdb-remote.target-definition-file /path/to/module.py

Inside module there should be a function:

def get_dynamic_setting(target, setting_name):

This dynamic setting function is handed the "target" which is a SBTarget, and the 
"setting_name", which is the name of the dynamic setting to retrieve. For the GDB
remote target definition the setting name is 'gdb-server-target-definition'. The
return value is a dictionary that follows the same format as the OperatingSystem
plugins follow. I have checked in an example file that implements the x86_64 GDB
register set for people to see:

    examples/python/x86_64_target_definition.py
    
This allows LLDB to debug to any archticture that is support and allows users to
define the registers contexts when the discovery packets (qRegisterInfo, qHostInfo)
are not supported by the remote GDB server.

A few benefits of doing this in Python:
1 - The dynamic register context was already supported in the OperatingSystem plug-in
2 - Register contexts can use all of the LLDB enumerations and definitions for things
    like lldb::Format, lldb::Encoding, generic register numbers, invalid registers 
    numbers, etc.
3 - The code that generates the register context can use the program to calculate the
    register context contents (like offsets, register numbers, and more)
4 - True dynamic detection could be used where variables and types could be read from 
    the target program itself in order to determine which registers are available since
    the target is passed into the python function.
    
This is designed to be used instead of XML since it is more dynamic and code flow and
functions can be used to make the dictionary.

Jason Molenda 8359214427 A few small enhancements to the diagnose-unwind command.
Change the simple-minded stack walk to not depend on lldb to unwind
the first frame.

Collect a list of Modules and Addresses seen while backtracing (with
both methods), display the image list output for all of those modules,
plus disassemble and image show-unwind any additional frames that
the simple backtrace was able to unwind through instead of just the 
lldb unwind algorithm frames.

Remove checks for older lldb's that didn't support -a for disassemble
or specifying the assembler syntax on x86 targets.

Enrico Granata c8b36f160c First iteration of a Python tracer module
This module uses Python's sys.settrace() mechanism so setup a hook that can log every significant operation
This is a first step in providing a good debugging experience of Python embedded in LLDB
This module comprises an OO infrastructure that wraps Python's tracing and inspecting mechanisms, plus a very simple logging tracer
Output from this tracer looks like:

call print_keyword_args from <module> @ 243 args are kwargs are {'first_name': 'John', 'last_name': 'Doe'}
running print_keyword_args @ 228 locals are {'kwargs': {'first_name': 'John', 'last_name': 'Doe'}}
running print_keyword_args @ 229 locals are {'key': 'first_name', 'value': 'John', 'kwargs': {'first_name': 'John', 'last_name': 'Doe'}}
first_name = John
running print_keyword_args @ 228 locals are {'key': 'first_name', 'value': 'John', 'kwargs': {'first_name': 'John', 'last_name': 'Doe'}}
running print_keyword_args @ 229 locals are {'key': 'last_name', 'value': 'Doe', 'kwargs': {'first_name': 'John', 'last_name': 'Doe'}}
last_name = Doe
running print_keyword_args @ 228 locals are {'key': 'last_name', 'value': 'Doe', 'kwargs': {'first_name': 'John', 'last_name': 'Doe'}}

the thread which has a bad backtrace and run this command -- a lot
of information about the stack frames, and an alternate backtrace
algorithm, will be used.  The information will often be sufficient
for a remote person to figure out why the backtrace failed.

Enrico Granata f58cececaa Initial checkin of a new project: LLDB Performance Testing Infrastructure
This is a very basic implementation of a library that easily allows to drive LLDB.framework to write test cases for performance

This is separate from the LLDB testsuite in test/ in that:
a) this uses C++ instead of Python to avoid measures being affected by SWIG
b) this is in very early development and needs lots of tweaking before it can be considered functionally complete
c) this is not meant to test correctness but to help catch performance regressions

There is a sample application built against the library (in darwin/sketch) that uses the famous sample app Sketch as an inferior to measure certain basic parameters of LLDB's behavior.
The resulting output is a PLIST much like the following:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

Greg Clayton c7bece56fa <rdar://problem/13069948>
Major fixed to allow reading files that are over 4GB. The main problems were that the DataExtractor was using 32 bit offsets as a data cursor, and since we mmap all of our object files we could run into cases where if we had a very large core file that was over 4GB, we were running into the 4GB boundary.

So I defined a new "lldb::offset_t" which should be used for all file offsets.

After making this change, I enabled warnings for data loss and for enexpected implicit conversions temporarily and found a ton of things that I fixed.

Any functions that take an index internally, should use "size_t" for any indexes and also should return "size_t" for any sizes of collections.

Greg Clayton a4d8747d0f <rdar://problem/13010007>
Added the ability for OS plug-ins to lazily populate the thread this. The python OS plug-in classes can now implement the following method:

class OperatingSystemPlugin:
  def create_thread(self, tid, context):
    # Return a dictionary for a new thread to create it on demand

This will add a new thread to the thread list if it doesn't already exist. The example code in lldb/examples/python/operating_system.py has been updated to show how this call us used.

Cleaned up the code in PythonDataObjects.cpp/h:
- renamed all classes that started with PythonData* to be Python*. 
- renamed PythonArray to PythonList. Cleaned up the code to use inheritance where
- Centralized the code that does ref counting in the PythonObject class to a single function.
- Made the "bool PythonObject::Reset(PyObject *)" function be virtual so each subclass can correctly check to ensure a PyObject is of the right type before adopting the object.
- Cleaned up all APIs and added new constructors for the Python* classes to they can all construct form:
	- PyObject *
	- const PythonObject &
	- const lldb::ScriptInterpreterObjectSP &

Cleaned up code in ScriptInterpreterPython:
- Made calling python functions safer by templatizing the production of value formats. Python specifies the value formats based on built in C types (long, long long, etc), and code often uses typedefs for uint32_t, uint64_t, etc when passing arguments down to python. We will now always produce correct value formats as the templatized code will "do the right thing" all the time.
- Fixed issues with the ScriptInterpreterPython::Locker where entering the session and leaving the session had a bunch of issues that could cause the "lldb" module globals lldb.debugger, lldb.target, lldb.process, lldb.thread, and lldb.frame to not be initialized.

Enrico Granata 21dfcd9d41 Implementing plugins that provide commands.
This checkin adds the capability for LLDB to load plugins from external dylibs that can provide new commands
It exports an SBCommand class from the public API layer, and a new SBCommandPluginInterface

There is a minimal load-only plugin manager built into the debugger, which can be accessed via Debugger::LoadPlugin.

Plugins are loaded from two locations at debugger startup (LLDB.framework/Resources/PlugIns and ~/Library/Application Support/LLDB/PlugIns) and more can be (re)loaded via the "plugin load" command

For an example of how to make a plugin, refer to the fooplugin.cpp file in examples/plugins/commands

Caveats:
	Currently, the new API objects and features are not exposed via Python.
	The new commands can only be "parsed" (i.e. not raw) and get their command line via a char** parameter (we do not expose our internal Args object)
	There is no unloading feature, which can potentially lead to leaks if you overwrite the commands by reloading the same or different plugins
	There is no API exposed for option parsing, which means you may need to use getopt or roll-your-own

Greg Clayton 1f7460716b <rdar://problem/11757916>
Make breakpoint setting by file and line much more efficient by only looking for inlined breakpoint locations if we are setting a breakpoint in anything but a source implementation file. Implementing this complex for a many reasons. Turns out that parsing compile units lazily had some issues with respect to how we need to do things with DWARF in .o files. So the fixes in the checkin for this makes these changes:
- Add a new setting called "target.inline-breakpoint-strategy" which can be set to "never", "always", or "headers". "never" will never try and set any inlined breakpoints (fastest). "always" always looks for inlined breakpoint locations (slowest, but most accurate). "headers", which is the default setting, will only look for inlined breakpoint locations if the breakpoint is set in what are consudered to be header files, which is realy defined as "not in an implementation source file". 
- modify the breakpoint setting by file and line to check the current "target.inline-breakpoint-strategy" setting and act accordingly
- Modify compile units to be able to get their language and other info lazily. This allows us to create compile units from the debug map and not have to fill all of the details in, and then lazily discover this information as we go on debuggging. This is needed to avoid parsing all .o files when setting breakpoints in implementation only files (no inlines). Otherwise we would need to parse the .o file, the object file (mach-o in our case) and the symbol file (DWARF in the object file) just to see what the compile unit was.
- modify the "SymbolFileDWARFDebugMap" to subclass lldb_private::Module so that the virtual "GetObjectFile()" and "GetSymbolVendor()" functions can be intercepted when the .o file contenst are later lazilly needed. Prior to this fix, when we first instantiated the "SymbolFileDWARFDebugMap" class, we would also make modules, object files and symbol files for every .o file in the debug map because we needed to fix up the sections in the .o files with information that is in the executable debug map. Now we lazily do this in the DebugMapModule::GetObjectFile()

Cleaned up header includes a bit as well.

Greg Clayton 784933b791 Enable the "symbolicate" interactive command to symbolicate all crash logs if no indexes are supplied. This can be handy to use as:
(lldb) script import lldb.macosx.crashlog
(lldb) crashlog -i /tmp/*.crash
% symbolicate --crashed-only

This will symbolicate all of the crash logs only for the crashed thread.

Also print out the crash log index number in the output of the interactive "image" command:

(lldb) script import lldb.macosx.crashlog
(lldb) crashlog -i /tmp/*.crash
% image LLDB.framework
...

This then allows you to symbolicate a crash log by index accurately when you looked for an image of a specific version

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:
