This works by creating a command backed by a class whose interface should - at least - include
def __init__(self, debugger, session_dict)
def __call__(self, args, return_obj, exe_ctx)
What works:
- adding a command via command script add --class
- calling a thusly created command
What is missing:
- support for custom help
- test cases
The missing parts will follow over the next couple of days
This is an improvement over the existing system as:
a) it provides an obvious location for commands to provide help strings (i.e. methods)
b) it allows commands to store state in an obvious fashion
c) it allows us to easily add features to script commands over time (option parsing and subcommands registration, I am looking at you :-)

A runtime support value is a ValueObject whose only purpose is to support some language runtime's operation, but it does not directly provide any user-visible benefit
As such, unless the user is working on the runtime support, it is mostly safe for them not to see such a value when debugging
It is a language runtime's job to check whether a ValueObject is a support value, and that - in conjunction with a target setting - is used by frame variable and target variable
SBFrame::GetVariables gets a new overload with yet another flag to dictate whether to return those support values to the caller - that which defaults to the setting's value

On Windows we copy python27(_d).dll to the bin directory. We do
this by looking at the PYTHON_LIBRARY specified by the user, which
is something like C:\foo\python27_d.lib, and replacing ".lib" with
".dll". But ".lib" as a regex will also match "flib", etc. So
make this a literal . instead of a wildcard .

CMake FindPythonLibs will look for multiple versions of Python
including both debug and release, and build up a list such as
(debug <debugpath> optimized <optimizedpath>). This confuses
the logic we have in CMake to copy the correct python dll to
the output directory so that it need not be in your system's PATH.
To alleviate this, we manually split this list and extract out
the debug and release versions of the python library, and copy
only the correct one to the output directory.

This allows LLDB to build into and install into correctly suffixed
libdirs. This is especially significant for LLDB because the python
extension building done by CMake directly uses multilib suffixes when
the host OS does, and the host OS will not always look back and forth
between them. As a consequence, before LLVM, Clang, and LLDB (and every
other subproject) had support for using LLVM_LIBDIR_SUFFIX, you couldn't
build or install LLDB on a multilib system with its python extensions

- Modified all places that use the SBLaunchInfo/SBAttachInfo and the internal ProcessLaunchInfo/ProcessAttachInfo to not take a listener as a parameter since it is in the launch/attach info now
- Load a module's sections by default when removing a module from a target. Since we create JIT modules for expressions and helper functions, we could end up with stale data in the section load list if a module was removed from the target as the section load list would still have entries for the unloaded module. Target now has the following functions to help unload all sections a single or multiple modules:
size_t
Target::UnloadModuleSections (const ModuleList &module_list);
size_t
Target::UnloadModuleSections (const lldb::ModuleSP &module_sp);

This works similarly to the {thread/frame/process/target.script:...} feature - you write a summary string, part of which is

This patch gives LLDB some ability to interact with AddressSanitizer runtime library, on top of what we already have (historical memory stack traces provided by ASan). Namely, that's the ability to stop on an error caught by ASan, and access the report information that are associated with it. The report information is also exposed into SB API.
More precisely this patch...
adds a new plugin type, InstrumentationRuntime, which should serve as a generic superclass for other instrumentation runtime libraries, these plugins get notified when modules are loaded, so they get a chance to "activate" when a specific dynamic library is loaded
an instance of this plugin type, AddressSanitizerRuntime, which activates itself when it sees the ASan dynamic library or founds ASan statically linked in the executable
adds a collection of these plugins into the Process class
AddressSanitizerRuntime sets an internal breakpoint on __asan::AsanDie(), and when this breakpoint gets hit, it retrieves the report information from ASan
this breakpoint is then exposed as a new StopReason, eStopReasonInstrumentation, with a new StopInfo subclass, InstrumentationRuntimeStopInfo
the StopInfo superclass is extended with a m_extended_info field (it's a StructuredData::ObjectSP), that can hold arbitrary JSON-like data, which is the way the new plugin provides the report data
the "thread info" command now accepts a "-s" flag that prints out the JSON data of a stop reason (same way the "-j" flag works now)
SBThread has a new API, GetStopReasonExtendedInfoAsJSON, which dumps the JSON string into a SBStream
adds a test case for all of this
I plan to also get rid of the original ASan plugin (memory history stack traces) and use an instance of AddressSanitizerRuntime for that purpose.

On a suggestion from Jim Ingham, this class allows you to very easily define synthetic child providers that return a synthetic value (in the sense of r219330), but no children
Also, document this new feature in our www docs
llvm-svn: 219337
The way to do this is to write a synthetic child provider for your type, and have it vend the (optional) get_value function.
If get_value is defined, and it returns a valid SBValue, that SBValue's value (as in lldb_private::Value) will be used as the synthetic ValueObject's Value
The rationale for doing things this way is twofold:
- there are many possible ways to define a "value" (SBData, a Python number, ...) but SBValue seems general enough as a thing that stores a "value", so we just trade values that way and that keeps our currency trivial
- we could introduce a new level of layering (ValueObjectSyntheticValue), a new kind of formatter (synthetic value producer), but that would complicate the model (can I have a dynamic with no synthetic children but synthetic value? synthetic value with synthetic children but no dynamic?), and I really couldn't see much benefit to be reaped from this added complexity in the matrix
On the other hand, just defining a synthetic child provider with a get_value but returning no actual children is easy enough that it's not a significant road-block to adoption of this feature
Comes with a test case

This script supports displaying developer-focused backtraces when working
with mixed Java and C/C++ stack frames within lldb. On Android, this represents
just about every app, since all apps start in Java code.
The script currently supports the Art JVM when run on host-side x86_64 and x86,
but does require a patch not yet accepted in AOSP:
AOSP patch: https://android-review.googlesource.com/#/c/106523/
The backtraces will hide Art VM machinery for interpreted and AOT code
and display the Java file/line numbers for Java code, while displaying
native backtrace info for native frames. Effectively the developer will
get an app-centric view of the call stack.
This script is not yet tested on device-side Art nor is it tested on
any architecture other than x86_64 or x86 32-bit. Several changes were
needed on the AOSP side to enable it to work properly for x86_64 and x86,
so it is quite likely we'll need to do something similar for other cpu
architectures as well.

_lldb is built as an extension module on Windows. Normally to load
an extension module named 'foo', Python would look for the file
'foo.pyd'. However, when a debug interpreter is used, Python will

configuration and creates the correct symlink name based on the
build configuration.
llvm-svn: 213306
This patch fixes a number of issues with embedded Python on
Windows. In particular:
1) The script that builds the python modules was normalizing the
case of python filenames during copies. The module name is
the filename, and is case-sensitive, so this was breaking code.
2) Changes the build to not attempt to link against python27.lib
(e.g. the release library) when linking against msvcrt debug
library. Doing a debug build of LLDB with embedded python
support now requires you to provide your own self-compiled
debug version of python.
3) Don't import termios when initializing the interpreter. This
is part of a larger effort to remove the dependency on termios
since it is not available on Windows. This particular instance
was unnecessary and unused.

This adds a new SBExpressionOptions::SetLanguage API for selecting a

I added adds a new SBThread::GetInfoItemByPathString for retriving
information about a thread from that thread's StructuredData.
I added a new StructuredData class for representing

Helper functions to read JSON and create a StructuredData object,
and to print a StructuredData object in JSON format are included.
A few Cocoa / Cocoa Touch data formatters were updated by Enrico
to track changes in iOS 8 / Yosemite.
Before we query a thread's extended information, the system runtime may
provide hints to the remote debug stub that it will use to retrieve values
out of runtime structures. I added a new SystemRuntime method
AddThreadExtendedInfoPacketHints which allows the SystemRuntime to add
key-value type data to the initial request that we send to the remote stub.
The thread-format formatter string can now retrieve values out of a thread's
extended info structured data. The default thread-format string picks up
two of these - thread.info.activity.name and thread.info.trace_messages.
I added a new "jThreadExtendedInfo" packet in debugserver; I will
add documentation to the lldb-gdb-remote.txt doc soon. It accepts
JSON formatted arguments (most importantly, "thread":threadnum) and
it returns a variety of information regarding the thread to lldb
in JSON format. This JSON return is scanned into a StructuredData
object that is associated with the thread; UI layers can query the
thread's StructuredData to see if key-values are present, and if
so, show them to the user. These key-values are likely to be
specific to different targets with some commonality among many
targets. For instance, many targets will be able to advertise the
pthread_t value for a thread.
I added an initial rough cut of "thread info" command which will print
the information about a thread from the jThreadExtendedInfo result.
I need to do more work to make this format reasonably.
Han Ming added calls into the pmenergy and pmsample libraries if
debugserver is run on Mac OS X Yosemite to get information about the

I added support to debugserver for gathering the Genealogy information
about threads, if it exists, and returning it in the jThreadExtendedInfo
JSON result.

Rationale:
Pretty simply, the idea is that sometimes type names are way too long and contain way too many details for the average developer to care about. For instance, a plain ol' vector of int might be shown as
std::__1::vector<int, std::__1::allocator<....
rather than the much simpler std::vector<int> form, which is what most developers would actually type in their code
Proposed solution:
Introduce a notion of "display name" and a corresponding API GetDisplayTypeName() to return such a crafted for visual representation type name
Obviously, the display name and the fully qualified (or "true") name are not necessarily the same - that's the whole point
LLDB could choose to pick the "display name" as its one true notion of a type name, and if somebody really needs the fully qualified version of it, let them deal with the problem
Or, LLDB could rename what it currently calls the "type name" to be the "display name", and add new APIs for the fully qualified name, making the display name the default choice
The choice that I am making here is that the type name will keep meaning the same, and people who want a type name suited for display will explicitly ask for one
It is the less risky/disruptive choice - and it should eventually make it fairly obvious when someone is asking for the wrong type
Caveats:
- for now, GetDisplayTypeName() == GetTypeName(), there is no logic to produce customized display type names yet.
- while the fully-qualified type name is still the main key to the kingdom of data formatters, if we start showing custom names to people, those should match formatters

The FreeBSD package building cluster installs e.g. 'python2.7', but no
plain 'python' to avoid version-related issues.
CMake's FindPythonInterp locates an interpreter with such a name and
provides it in the PYTHON_EXECUTABLE variable. Use that if it's set,
falling back to the original '/usr/bin/env python' otherwise.

Bug fix for pr18841:
http://llvm.org/bugs/show_bug.cgi?id=18841
This change creates a stub Python readline.so module that does almost
nothing. Its whole purpose is to prevent Python from loading the real
module, something it does during the embedded Python interpreter's
initialization sequence (and way before lldb ever requests it within
embedded_interpreter.py).
On Ubuntu 12.04 and 13.10 x86_64, and in the Python 2.7.6 tree, the
stock Python readline module links against the GNU readline library.
This appears to be the case on all Pythons except where __APPLE__ is
defined. LLDB now requires linking against the libedit library.
Something about having both libedit.so and libreadline.so linked into
the same process space is causing the Python readline.so to trigger a
NULL memory access. I have put in a separate patch to python.org.
This suppression of embedded interpreter readline support can be
removed if at least any one of the following happens:
1. The stock python distribution accepts a patch similar to what I
submitted to Python 2.7.6's Modules/readline.c file.
2. The stock python distribution implements Modules/readline.c in
terms of libedit's readline compatibility mode (i.e. essentially
compiles it the way __APPLE__ compiles that module) under Linux.
3. a clean-room implementation of the python readline module is
implemented against libedit (either readline compatibility mode or
native libedit). This could be implemented within the readline.cpp
file that this change introduces. It cannot be a fork of python's
readline.c module due to llvm licensing.
The net effect of this change on Linux is that the embedded python's
readline support will not exist.

PyTuple_SetItem steals a reference to the item it inserts in the tuple

The many many benefits include:
1 - Input/Output/Error streams are now handled as real streams not a push style input
2 - auto completion in python embedded interpreter
3 - multi-line input for "script" and "expression" commands now allow you to edit previous/next lines using up and down arrow keys and this makes multi-line input actually a viable thing to use
4 - it is now possible to use curses to drive LLDB (please try the "gui" command)
We will need to deal with and fix any buildbot failures and tests and arise now that input/output and error are correctly hooked up in all cases.

The "type format add" command gets a new flag --type (-t). If you pass -t <sometype>, upon fetching the value for an object of your type,
LLDB will display it as-if it was of enumeration type <sometype>
This is useful in cases of non-contiguous enums where there are empty gaps of unspecified values, and as such one cannot type their variables as the enum type,
but users would still like to see them as-if they were of the enum type (e.g. DWARF field types with their user-reserved ranges)

the inferior function calling mechanism in lldb begun in Greg's patch r194009.
It removes a handful of alternate calls into the ClangUserExpression/ClangFunction/ThreadPlanCallFunction which
were there for convenience. Using the EvaluateExpressionOptions removes the need for them.
Using that it gets the --debug option from Greg's patch to work cleanly.
It also adds another EvaluateExpressionOption to not trap exceptions when running expressions. You shouldn't
use this option unless you KNOW your expression can't throw beyond itself. This is:

is currently the only subclass and the methods that Frame vends are

Update all callers to use Frame*/Frame& instead of pointers to
StackFrames.
This is almost entirely a mechanical change that touches a lot of
the code base so I'm committing it alone. No new functionality is
added with this patch, no new subclasses of Frame exist yet.
I'll probably need to tweak some of the separation, possibly moving
some of StackFrame's methods up in to Frame, but this is a good
starting point.

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.
llvm-svn: 192646
This is implemented by means of a get_dynamic_setting(target, setting_name) function vended by the Python module, which can respond to arbitrary string names with dynamically constructed
settings objects (most likely, some of those that PythonDataObjects supports) for LLDB to parse
This needs to be hooked up to the debugger via some setting to allow users to specify which module will vend the information they want to supply

Implement SBTarget::CreateValueFromAddress() with a behavior equivalent to SBValue::CreateValueFromAddress()
(but without the need to grab an SBValue first just as a starting point to make up another SBValue out of whole cloth)
llvm-svn: 192239
This allows the PC to be directly changed to a different line.
It's similar to the example python script in examples/python/jump.py, except implemented as a builtin.
Also this version will track the current function correctly even if the target line resolves to multiple addresses. (e.g. debugging a templated function)
llvm-svn: 190572
Summary:
This merge brings in the improved 'platform' command that knows how to
interface with remote machines; that is, query OS/kernel information, push
and pull files, run shell commands, etc... and implementation for the new
communication packets that back that interface, at least on Darwin based
operating systems via the POSIXPlatform class. Linux support is coming soon.
Verified the test suite runs cleanly on Linux (x86_64), build OK on Mac OS
X Mountain Lion.
Additional improvements (not in the source SVN branch 'lldb-platform-work'):
- cmake build scripts for lldb-platform
- cleanup test suite
- documentation stub for qPlatform_RunCommand
- use log class instead of printf() directly
- reverted work-in-progress-looking changes from test/types/TestAbstract.py that work towards running the test suite remotely.
- add new logging category 'platform'

OS Plugins' __init__ method takes two arguments: (self,process)

llvm-svn: 185240
The semi-unofficial way of returning a status from a Python command was to return a string (e.g. return "no such variable was found") that LLDB would pick as a clue of an error having happened
This checkin changes that:
- SBCommandReturnObject now exports a SetError() call, which can take an SBError or a plain C-string
- script commands now drop any return value and expect the SBCommandReturnObject ("return object") to be filled in appropriately - if you do nothing, a success will be assumed
If your commands were relying on returning a value and having LLDB pick that up as an error, please change your commands to SetError() through the return object or expect changes in behavior
llvm-svn: 184893
Now, the way SWIG wrappers call into Python is through a utility PyCallable object, which overloads operator () to look like a normal function call
Plus, using the SBTypeToSWIGWrapper() family of functions, we can call python functions transparently as if they were plain C functions
Using this new technique should make adding new Python call points easier and quicker
The PyCallable is a generally useful facility, and we might want to consider moving it to a separate layer where other parts of LLDB can use it
llvm-svn: 184608
Any time a SWIG wrapper needs a PyObject for an SB object, it now should call into SBTypeToSWIGWrapper<SBType>(SBType*)
If you try to use it on an SBType for which there is not an implementation yet, LLDB will fail to link - just add your specialization to python-swigsafecast.swig and rebuild
This is the first step in simplifying our SWIG Wrapper layer

Specifically, the ${target ${process ${thread and ${frame specifiers have been extended to allow a subkeyword .script:<fctName> (e.g. ${frame.script:FooFunction})
The functions are prototyped as

This has not been implemented for ${var because it would be akin to a Python summary which is already well-defined in LLDB

Python breakpoint actions can return False to say that they don't want to stop at the breakpoint to which they are associated
Almost all of the work to support this notion of a breakpoint callback was in place, but two small moving parts were missing:
a) the SWIG wrapper was not checking the return value of the script
b) when passing a Python function by name, the call statement was dropping the return value of the function
This checkin addresses both concerns and makes this work
Care has been taken that you only keep running when an actual value of False has been returned, and that any other value (None included) means Stop!

Two reasons for that:

Introducing a negative cache for ObjCLanguageRuntime::LookupInCompleteClassCache()
This helps speed up the (common) case of us looking for classes that are hidden deep within Cocoa internals and repeatedly failing at finding type information for them.
In order for this to work, we need to clean this cache whenever debug information is added. A new symbols loaded event is added that is triggered with add-dsym (before modules loaded would be triggered for both adding modules and adding symbols).
Interested parties can register for this event. Internally, we make sure to clean the negative cache whenever symbols are added.
Lastly, ClassDescriptor::IsTagged() has been refactored to GetTaggedPointerInfo() that also (optionally) returns info and value bits. In this way, data formatters can share tagged pointer code instead of duplicating the required arithmetic.

Making value objects properly iterable in constructs of the form
[ x for x in value_with_children ]
This would previously cause an endless loop because lacking a proper iterator object, Python will keep calling __getitem__() with increasing values of the index until it gets an IndexError
since SBValue::GetValueForExpressionPath() supports synthetic array members, no array index will ever really cause an IndexError to be raised, hence the endless iteration

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.

- 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.

Adding FindFirstGlobalVariable to SBModule and SBTarget
These calls work like FindGlobalVariables but they only return the first match found and so they can return an SBValue instead of an SBValueList for added convenience of use

Added a unique integer identifier to processes. Some systems, like JTAG or other simulators, might always assign the same process ID (pid) to the processes that are being debugged. In order for scripts and the APIs to uniquely identify the processes, there needs to be another ID. Now the SBProcess class has:
uint32_t SBProcess::GetUniqueID();
This integer ID will help to truly uniquely identify a process and help with appropriate caching that can be associated with a SBProcess object.

controlled by the --unwind-on-error flag, and --ignore-breakpoint which separately controls behavior when a called
function hits a breakpoint. For breakpoints, we don't unwind, we either stop, or ignore the breakpoint, which makes
more sense.
Also make both these behaviors globally settable through "settings set".
Also handle the case where a breakpoint command calls code that ends up re-hitting the breakpoint. We were recursing
and crashing. Now we just stop without calling the second command.

As with llvm svn r172138, this patch is basically copying some changes that
we've been using for building clang at Apple. Besides cleaning it up to use
xcrun to locate the proper versions of tools, especially for cross compiling,
it fixes the build to work with newer versions of clang that honor SDKROOT
settings in the environment.

This script used an inconsistent mix of spaces and tabs, and even
ignoring that, it still had inconsistent indentation, which is
pretty scary for a Python script. I also removed trailing whitespace
from some lines.
llvm-svn: 172237
Added SBTarget::EvaluateExpression() so expressions can be evaluated without needing a process.
Also fixed many functions that deal with clang AST types to be able to properly handle the clang::Type::Elaborated types ("struct foo", "class bar").

Added a "step-in-target" flag to "thread step-in" so if you have something like:
Process 28464 stopped
* thread #1: tid = 0x1c03, function: main , stop reason = breakpoint 1.1
frame #0: 0x0000000100000e08 a.out`main at main.c:62
61
-> 62 int A6 = complex (a(4), b(5), c(6)); // Stop here to step targetting b and hitting breakpoint.
63
and you want to get into "complex" skipping a, b and c, you can do:
(lldb) step -t complex
Process 28464 stopped
* thread #1: tid = 0x1c03, function: complex , stop reason = step in
frame #0: 0x0000000100000d0d a.out`complex at main.c:44
41
42 int complex (int first, int second, int third)
43 {
-> 44 return first + second + third; // Step in targetting complex should stop here
45 }
46
47 int main (int argc, char const *argv[])

lldb.target
lldb.process
lldb.thread
lldb.frame
are initialized to at least contain empty lldb classes in case some python gets imported that uses them.
