size_t
SBProcess::ReadCStringFromMemory (addr_t addr, void *buf, size_t size, lldb::SBError &error);
uint64_t
SBProcess::ReadUnsignedFromMemory (addr_t addr, uint32_t byte_size, lldb::SBError &error);
lldb::addr_t
SBProcess::ReadPointerFromMemory (addr_t addr, lldb::SBError &error);
These ReadCStringFromMemory() has some SWIG type magic that makes it return the
python string directly and the "buf" is not needed:
error = SBError()
max_cstr_len = 256
cstr = lldb.process.ReadCStringFromMemory (0x1000, max_cstr_len, error)
if error.Success():
....
The other two functions behave as expteced. This will make it easier to get integer values
from the inferior process that are correctly byte swapped. Also for pointers, the correct
pointer byte size will be used.
Also cleaned up a few printf style warnings for the 32 bit lldb build on darwin.

lldb::SBValue::CreateValueFromAddress does not verify SBType::GetPointerType succeeds
SBValue::CreateValueFromAddress() should check the validity of type and its derived pointer type
before using it. Add a test case.

clients to disassemble a series of raw bytes as
demonstrated by a new testcase.
In the future, this API will also allow clients
to provide a callback that adds comments for
addresses in the disassembly.
I also modified the SWIG harness to ensure that
Python ByteArrays work as well as strings as
sources of raw data.

will allow us to represent a process/thread ID using a pointer for the OS
plug-ins where they might want to represent the process or thread ID using
the address of the process or thread structure.

Fixed an issue where if we are debugging on a remote platform and set a
platform path for our executable, it was not being honored by the new
launch functions that used the ProcessLaunchInfo.

the thread specific data and were destroying the thread specfic data more
than once.
Also added the ability to ask a lldb::StateType if it is stopped with an
additional paramter of "must_exist" which means that the state must be a
stopped state for a process that still exists. This means that eStateExited
and eStateUnloaded will no longer return true if "must_exist" is set to true.
llvm-svn: 144875
info for us to attach by pid, or by name and will also allow us to eventually
do a lot more powerful attaches. If you look at the options for the "platform
process list" command, there are many options which we should be able to
specify. This will allow us to do things like "attach to a process named 'tcsh'
that has a parent process ID of 123", or "attach to a process named 'x' which
has an effective user ID of 345".
I finished up the --shell implementation so that it can be used without the
--tty option in "process launch". The "--shell" option now can take an
optional argument which is the path to the shell to use (or a partial name
like "sh" which we will find using the current PATH environment variable).
Modified the Process::Attach to use the new ProcessAttachInfo as the sole
argument and centralized a lot of code that was in the "process attach"
Execute function so that everyone can take advantage of the powerful new
attach functionality.

Fixed an issues with the SBType and SBTypeMember classes:
- Fixed SBType to be able to dump itself from python
- Fixed SBType::GetNumberOfFields() to return the correct value for objective C interfaces
- Fixed SBTypeMember to be able to dump itself from python
- Fixed the SBTypeMember ability to get a field offset in bytes (the value
being returned was wrong)
- Added the SBTypeMember ability to get a field offset in bits
Cleaned up a lot of the Stream usage in the SB API files.
llvm-svn: 144493
the --tty option. So you can now get shell expansion and file redirection:
(lldb) process launch --tty --shell -- *.jpg < in.txt > out.txt
Again, the "--tty" is mandatory for now until we hook this up to other
functions. The shell is also currently hard coded to "/bin/bash" and not the
"SHELL" variable. "/bin/tcsh" was causing problems which I need to dig into.

string to avoid possible later crashes.
Modified the locations that do set the crash description to NULL out the
string when they are done doing their tasks.

- If you download and build the sources in the Xcode project, x86_64 builds
by default using the "llvm.zip" checkpointed LLVM.
- If you delete the "lldb/llvm.zip" and the "lldb/llvm" folder, and build the
Xcode project will download the right LLVM sources and build them from
scratch
- If you have a "lldb/llvm" folder already that contains a "lldb/llvm/lib"
directory, we will use the sources you have placed in the LLDB directory.
Python can now be disabled for platforms that don't support it.
Changed the way the libllvmclang.a files get used. They now all get built into
arch specific directories and never get merged into universal binaries as this
was causing issues where you would have to go and delete the file if you wanted
to build an extra architecture slice.
llvm-svn: 143678
on internal only (public API hasn't changed) to simplify the paramter list
to the launch calls down into just one argument. Also all of the argument,
envronment and stdio things are now handled in a much more centralized fashion.
llvm-svn: 143656
lldb_private::Error objects the rules are:
- short strings that don't start with a capitol letter unless the name is a
class or anything else that is always capitolized
- no trailing newline character
- should be one line if possible
Implemented a first pass at adding "--gdb-format" support to anything that
accepts format with optional size/count.
llvm-svn: 142999
process IDs, and thread IDs, but was mainly needed for for the UserID's for
Types so that DWARF with debug map can work flawlessly. With DWARF in .o files
the type ID was the DIE offset in the DWARF for the .o file which is not
unique across all .o files, so now the SymbolFileDWARFDebugMap class will
make the .o file index part (the high 32 bits) of the unique type identifier
so it can uniquely identify the types.
llvm-svn: 142534
watchpoint modify -c 'global==5'
modifies the last created watchpoint so that the condition expression
is evaluated at the stop point to decide whether we should proceed with
the stopping.
Also add SBWatchpont::SetCondition(const char *condition) to set condition
programmatically.
Test cases to come later.
llvm-svn: 142227
a watchpoint for either the variable encapsulated by SBValue (Watch) or the pointee
encapsulated by SBValue (WatchPointee).
Removed SBFrame::WatchValue() and SBFrame::WatchLocation() API as a result of that.
Modified the watchpoint related test suite to reflect the change.
Plus replacing WatchpointLocation with Watchpoint throughout the code base.
There are still cleanups to be dome. This patch passes the whole test suite.
Check it in so that we aggressively catch regressions.
llvm-svn: 141925
SymbolFIle (it was done mostly in the BreakpointResolverName resolver before.) Then
tailor our searches to the way the indexed maps are laid out. This removes a bunch
of test case failures using indexed dSYM's.
llvm-svn: 141428
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
Also add rich comparison methods (__eq__ and __ne__) for SBWatchpointLocation.
Modify TestWatchpointLocationIter.py to exercise the new APIs.
Add fuzz testings for the recently added SBTarget APIs related to watchpoint manipulations.
llvm-svn: 140633
to the Python interface.
Implement yet another (threre're 3 now) iterator protocol for SBTarget: watchpoint_location_iter(),
to iterate on the available watchpoint locations. And add a print representation for
SBWatchpointLocation.
Exercise some of these Python API with TestWatchpointLocationIter.py.
llvm-svn: 140595
iterate on the available watchpoint locations and to perform watchpoint manipulations.
I still need to export the SBWatchpointLocation class as well as the added watchpoint
manipulation methods to the Python interface. And write test cases for them.
llvm-svn: 140575
symbolication. Also improved the SBInstruction API to allow
access to the instruction opcode name, mnemonics, comment and
instruction data.
Added the ability to edit SBLineEntry objects (change the file,
line and column), and also allow SBSymbolContext objects to be
modified (set module, comp unit, function, block, line entry
or symbol).
The SymbolContext and SBSymbolContext can now generate inlined
call stack infomration for symbolication much easier using the
SymbolContext::GetParentInlinedFrameInfo(...) and
SBSymbolContext::GetParentInlinedFrameInfo(...) methods.
llvm-svn: 140518
contents starting at an offset (2 separate methods). This helps
the scripting interface stay more natural by allowing both from
Python.
Added the ability to dump data with address annotations when
call SBData::GetDescription().
Hooked up the SBSection to the __repr__ so you can print section
objects from within python.
Improved the dumping of symbols from python.
Fixed the .i interface references which were set to "Relative to this Group"
which somehow included Jim's "lldb-clean" root directory in the path. The
interfaces are now in a folder called "interfaces" withing the Xcode API
subfolder.
llvm-svn: 140451
- New SBSection objects that are object file sections which can be accessed
through the SBModule classes. You can get the number of sections, get a
section at index, and find a section by name.
- SBSections can contain subsections (first find "__TEXT" on darwin, then
us the resulting SBSection to find "__text" sub section).
- Set load addresses for a SBSection in the SBTarget interface
- Set the load addresses of all SBSection in a SBModule in the SBTarget interface
- Add a new module the an existing target in the SBTarget interface
- Get a SBSection from a SBAddress object
This should get us a lot closer to being able to symbolicate using LLDB through
the public API.
llvm-svn: 140437
set a watchpoint Pythonically. If the find-and-watch-a-variable operation
fails, an invalid SBValue is returned, instead.
Example Python usage:
value = frame0.WatchValue('global',
lldb.eValueTypeVariableGlobal,
lldb.LLDB_WATCH_TYPE_READ|lldb.LLDB_WATCH_TYPE_WRITE)
Add TestSetWatchpoint.py to exercise this API.
We have 400 test cases now.
llvm-svn: 140436
etc to specific source files.
Added SB API's to specify these source files & also more than one module.
Added an "exact" option to CompileUnit's FindLineEntry API.
llvm-svn: 140362
shared pointers.
Changed the ExecutionContext over to use shared pointers for
the target, process, thread and frame since these objects can
easily go away at any time and any object that was holding onto
an ExecutionContext was running the risk of using a bad object.
Now that the shared pointers for target, process, thread and
frame are just a single pointer (they all use the instrusive
shared pointers) the execution context is much safer and still
the same size.
Made the shared pointers in the the ExecutionContext class protected
and made accessors for all of the various ways to get at the pointers,
references, and shared pointers.
