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.

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.

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.

to find data on the heap. To use this, make the project and then when stopped in your
lldb debug session:
(lldb) process load /path/to/libheap.dylib
(lldb) find_pointer_in_heap (0x112233000000)
This will grep everything in all active allocation blocks and print and malloc blocks that contain the pointer 0x112233000000.
This can also work for c strings:
(lldb) find_cstring_in_heap ("hello")

functions that can create file descriptors and close them. It will warn when
there close file descriptor call that returns with EBADF and show the
corresponding stack backtraces that caused the issue. It will also log all
file descriptor create and delete calls. See the comments at the top of
FDInterposing.cpp for all of the details.

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.

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.

- all instances of "vobj" have been renamed to "valobj"
- class Debugger::Formatting has been renamed to DataVisualization (defined in FormatManager.h/cpp)
The interface to this class has not changed
- FormatCategory now uses ConstString's as keys to the navigators instead of repeatedly casting
from ConstString to const char* and back all the time
Next step is making the same happen for categories themselves
- category gnu-libstdc++ is defined in the constructor for a FormatManager
The source code for it is defined in gnu_libstdcpp.py, drawn from examples/synthetic at compile time
All references to previous 'osxcpp' name have been removed from both code and file names
Functional changes:
- the name of the option to use a summary string for 'type summary add' has changed from the previous --format-string
to the new --summary-string. It is expected that the short option will change from -f to -s, and -s for --python-script
will become -o
llvm-svn: 137886
new --raw-output (-R) option to frame variable prevents using summaries and synthetic children
other future formatting enhancements will be excluded by using the -R option
test case enhanced to check that -R works correctly
llvm-svn: 137185
The synthetic children providers now use the new (safer) APIs to get the values of objects
As a side effect, fixed an issue in ValueObject where ResolveValue() was not always updating the value before reading it
llvm-svn: 136861
- Completely new implementation of SBType
- Various enhancements in several other classes
Python synthetic children providers for std::vector<T>, std::list<T> and std::map<K,V>:
- these return the actual elements into the container as the children of the container
- basic template name parsing that works (hopefully) on both Clang and GCC
- find them in examples/synthetic and in the test suite in functionalities/data-formatter/data-formatter-python-synth
New summary string token ${svar :
- the syntax is just the same as in ${var but this new token lets you read the values
coming from the synthetic children provider instead of the actual children
- Python providers above provide a synthetic child len that returns the number of elements
into the container
Full bug fix for the issue in which getting byte size for a non-complete type would crash LLDB
Several other fixes, including:
- inverted the order of arguments in the ClangASTType constructor
- EvaluationPoint now only returns SharedPointer's to Target and Process
- the help text for several type subcommands now correctly indicates argument-less options as such
