Summary:
Several changes to fix CMake builds of LLDB with the
BUILD_SHARED_LIBS setting on.
- Force all internal libraries to be built STATIC.
- Add additional library dependencies (pthread, dl,
runtimedyld).
- modify finalisation of SWIG wrapper to symlink the
"lib" dir into python/site-packages, so _lldb.so's
RPATH resolves.
Test Plan: Verified one test case with "dotest.py".

Previously we would pass an argument to finishSwigWrapperClasses.py which
specified whether this was a debug or a release build. But sometimes
CMAKE_BUILD_TYPE would not be set to anything, causing this argument
to be empty when passed in. The only purpose of this argument was to
determine whether or not to append _d to the extension module when
creating the symlink. This is only necessary when doing a debug
build of LLDB on Windows, which implies a debug interpreter, so we
replace this with a check to see if the running interpreter is a debug
one, and append _d if so.

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

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
enabled. With this patch (on top of all the others I have submitted
throughout the project), I'm finally able to build and install LLDB on
my system with Python support enabled. I'm also able to actually run the

Fixed include:
- Change Platform::ResolveExecutable(...) to take a ModuleSpec instead of a FileSpec + ArchSpec to help resolve executables correctly when we have just a path + UUID (no arch).
- Add the ability to set the listener in SBLaunchInfo and SBAttachInfo in case you don't want to use the debugger as the default listener.
- 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);

This works similarly to the {thread/frame/process/target.script:...} feature - you write a summary string, part of which is
${var.script:someFuncName}
someFuncName is expected to be declared as

Since . -> [] are the only allowed separators, and % is used for custom formatting, .script: would not be a legitimate symbol anyway, which makes this non-ambiguous

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

the user level. It adds the ability to invent new stepping modes implemented by python classes,
and to view the current thread plan stack and to some extent alter it.
I haven't gotten to documentation or tests yet. But this should not cause any behavior changes

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.

For the Objective-C case, we do not have a "function type" notion, so we actually end up wrapping the clang ObjCMethodDecl in the Impl object, and ask function-y questions of it
In general, you can always ask for return type, number of arguments, and type of each argument using the TypeMemberFunction layer - but in the C++ case, you can also acquire a Type object for the function itself, which instead you can't do in the Objective-C case

_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
look for the file 'foo_d.pyd'. This change checks the build
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
language of an expression.
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
inferior's power use.
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

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.

libldi library to collect extended backtrace information; switch
to the libBacktraceRecording library and its APIs. Complete the
work of adding QueueItems to Queues and allow for the QueueItems
to be interrogated about their extended backtraces in turn.
There's still cleanup and documentation to do on this code but the
code is functional and I it's a good time to get the work-in-progress
checked in.

PyTuple_SetItem steals a reference to the item it inserts in the tuple
This, plus the Py_XDECREF of the tuple a few lines below, causes our session dictionary to go away after the first time a SWIG layer function is called - with disastrous effects for the first subsequent attempt to use any functionality in ScriptInterpreterPython
This fixes it

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.

SBType SBType::GetTypedefedType();
Also added the ability to get a type by type ID from a SBModule:
SBType SBModule::GetTypeByID (lldb::user_id_t uid);

"Open LLDB and run:
(lldb) script print lldb.debugger.GetInputFileHandle()
This puts the debugger into a catatonic state and all interactions seem
to enter a black hole. The reason is that executing this commnand
actually *CLOSES* the input file handle and so all input is dropped on
the floor. Oof!
The fix is simple: flush a descriptor, instead of closing it, when
transferring ownership."

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 SB API has also been improved to handle both types of formats, and a test case is added

libdispatch aka Grand Central Dispatch (GCD) queues. Still fleshing out the
documentation and testing of these but the overall API is settling down so it's
a good time to check it in.

This patch adds a new lldb_private::SectionLoadHistory class that tracks what shared libraries were loaded given a process stop ID. This allows us to keep a history of the sections that were loaded for a time T. Many items in history objects will rely upon the process stop ID in the future.

the installed SDK to using the current OS installed headers/libraries.
This change is to address the removal of the Python framework
from the Mac OS X 10.9 (Mavericks) SDK, and is the recommended
workaround via https://developer.apple.com/library/mac/technotes/tn2328/_index.html

Example code:
remote_platform = lldb.SBPlatform("remote-macosx");
remote_platform.SetWorkingDirectory("/private/tmp")
debugger.SetSelectedPlatform(remote_platform)
connect_options = lldb.SBPlatformConnectOptions("connect://localhost:1111");
err = remote_platform.ConnectRemote(connect_options)
if err.Success():
print >> result, 'Connected to remote platform:'
print >> result, 'hostname: %s' % (remote_platform.GetHostname())
src = lldb.SBFileSpec("/Applications/Xcode.app/Contents/SharedFrameworks/LLDB.framework", False)
dst = lldb.SBFileSpec()
# copy src to platform working directory since "dst" is empty
err = remote_platform.Install(src, dst);
if err.Success():
print >> result, '%s installed successfully' % (src)
else:
print >> result, 'error: failed to install "%s": %s' % (src, err)
Implemented many calls needed in lldb-platform to be able to install a directory that contains symlinks, file and directories.
The remote lldb-platform can now launch GDB servers on the remote system so that remote debugging can be spawned through the remote platform when connected to a remote platform.
The API in SBPlatform is subject to change and will be getting many new functions.

(and same thing to Thread base class) which can be used when looking
at an ExtendedBacktrace thread; it will try to find the IndexID() of
the original thread that was executing this backtrace when it was
recorded. If lldb can't find a record of that thread, it will return
the same value as IndexID() for the ExtendedBacktrace thread.

It completes the job of using EvaluateExpressionOptions consistently throughout
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:
<rdar://problem/15374885>
At present this is only available through the SB API's or python.
It fixes a bug where function calls would unset the ObjC & C++ exception breakpoints without checking whether
they were set by somebody else already.

pure virtual base class and made StackFrame a subclass of that. As
I started to build on top of that arrangement today, I found that it
wasn't working out like I intended. Instead I'll try sticking with
the single StackFrame class -- there's too much code duplication to
make a more complicated class hierarchy sensible I think.
llvm-svn: 193983
defines a protocol that all subclasses will implement. StackFrame
is currently the only subclass and the methods that Frame vends are
nearly identical to StackFrame's old methods.
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'
