Jim Ingham 66243847a5 Remember to restore the frame in the exe_ctx passed in to RunThreadPlan.
Also, default "source_init_file" to False in the version of SBDebugger::Create
so that we don't pick up the init file in Python.

Jim Ingham 06942690b1 Add a version of SBDebugger::Create which allows us to specify whether to source
in the init files or not.

Jim Ingham 16e0c68627 Make ValueObject::SetValueFromCString work correctly.
Also change the SourceInitFile to look for .lldb-<APPNAME> and source that
preferentially if it exists.
Also made the breakpoint site report its address as well as its breakpoint number
when it gets hit and can't find any the associated locations (usually because the
breakpoint got disabled or deleted programmatically between the time it was hit
and reported.)
Changed ThreadPlanCallFunction to initialize the ivar m_func in the initializers of the
constructor, rather than waiting to initialize till later on in the function.
Fixed a bug where if you make an SBError and the ask it Success, it returns false.
Fixed ValueObject::ResolveValue so that it resolves a temporary value, rather than
overwriting the one in the value object.

Greg Clayton f3dd93c888 Added the notion of an system root for SDKs. This is a directory where all
libraries and headers exist. This can be specified using the platform select
function:

platform select --sysroot /Volumes/remote-root remote-macosx

Each platform subclass is free to interpret the sysroot as needed.

Expose the new SDK root directory through the SBDebugger class. 

Fixed an issue with the GDB remote protocol where unimplemented packets were
not being handled correctly.

Johnny Chen 3794ad95a7 Add an API to SBDebugger class:
bool SBDebugger::DeleteTarget(lldb::SBTarget &target);

which is used in the test tearDown() phase to cleanup the debugger's target list
so that it won't grow larger and larger as test cases are executed.  This is also
a good opportunity to get rid of the arcane requirement that test cases exercising
the Python API must assign the process object to self.process so that it gets
shutdown gracefully.  Instead, the shutdown of the process associated with each
target is now being now automatically.

Also get rid of an API from SBTarget class:

    SBTarget::DeleteTargetFromList(lldb_private::TargetList *list);

Greg Clayton fc3f027d33 Don't have the debugger default to ignoring EOF. This is only what the driver
(or anything running in a terminal) wants. Not what a UI (Xcode) would want 
where it creates a debugger per debug window. The current code had an infinite
loop after a debug session ended.

Caroline Tice 9088b06899 Make sure writing asynchronous output only backs up
& overwrites prompt if the IOChannel input reader is the top
input reader.

llvm-svn: 131110
2011-05-09 23:06:58 +00:00
Caroline Tice 969ed3d10f This patch captures and serializes all output being written by the
command line driver, including the lldb prompt being output by
editline, the asynchronous process output & error messages, and
asynchronous messages written by target stop-hooks.

As part of this it introduces a new Stream class,
StreamAsynchronousIO.  A StreamAsynchronousIO object is created with a
broadcaster, who will eventually broadcast the stream's data for a
listener to handle, and an event type indicating what type of event
the broadcaster will broadcast.  When the Write method is called on a
StreamAsynchronousIO object, the data is appended to an internal
string.  When the Flush method is called on a StreamAsynchronousIO
object, it broadcasts it's data string and clears the string.

Anything in lldb-core that needs to generate asynchronous output for
the end-user should use the StreamAsynchronousIO objects.

I have also added a new notification type for InputReaders, to let
them know that a asynchronous output has been written. This is to
allow the input readers to, for example, refresh their prompts and
lines, if desired.  I added the case statements to all the input
readers to catch this notification, but I haven't added any code for
handling them yet (except to the IOChannel input reader).

Greg Clayton 2289fa4820 Added the ability to set the Platform path for a module through the SBModule
interface.

Added a quick way to set the platform though the SBDebugger interface. I will
actually an a SBPlatform support soon, but for now this will do.

ConnectionFileDescriptor can be passed a url formatted as: "fd://<fd>" where
<fd> is a file descriptor in the current process. This is handy if you have
services, deamons, or other tools that can spawn processes and give you a
file handle.

Greg Clayton 431ce67823 Fixed an issue where if you specify an architecture from the command line like:
$ lldb --arch i386-unknown-unknown a.out

It would then create a target with only the "i386" part due to 
SBDebugger::GetDefaultArchitecture(...) truncating the arch triple due to the
way things used to be.

llvm-svn: 129731
2011-04-18 23:15:17 +00:00
Greg Clayton eb0103f2d0 Modified the ArchSpec to take an optional "Platform *" when setting the triple.
This allows you to have a platform selected, then specify a triple using
"i386" and have the remaining triple items (vendor, os, and environment) set
automatically.

Many interpreter commands take the "--arch" option to specify an architecture
triple, so now the command options needed to be able to get to the current
platform, so the Options class now take a reference to the interpreter on
construction.

Modified the build LLVM building in the Xcode project to use the new
Xcode project level user definitions:

LLVM_BUILD_DIR - a path to the llvm build directory
LLVM_SOURCE_DIR - a path to the llvm sources for the llvm that will be used to build lldb
LLVM_CONFIGURATION - the configuration that lldb is built for (Release, 
Release+Asserts, Debug, Debug+Asserts).

I also changed the LLVM build to not check if "lldb/llvm" is a symlink and
then assume it is a real llvm build directory versus the unzipped llvm.zip
package, so now you can actually have a "lldb/llvm" directory in your lldb
sources.

Greg Clayton e0d378b334 Fixed the LLDB build so that we can have private types, private enums and
public types and public enums. This was done to keep the SWIG stuff from
parsing all sorts of enums and types that weren't needed, and allows us to
abstract our API better.

2011-03-24 21:19:54 +00:00
Greg Clayton fc36f79170 Abtracted the innards of lldb-core away from the SB interface. There was some
overlap in the SWIG integration which has now been fixed by introducing
callbacks for initializing SWIG for each language (python only right now).
There was also a breakpoint command callback that called into SWIG which has
been abtracted into a callback to avoid cross over as well.

Added a new binary: lldb-platform

This will be the start of the remote platform that will use as much of the 
Host functionality to do its job so it should just work on all platforms.
It is pretty hollowed out for now, but soon it will implement a platform
using the GDB remote packets as the transport.

llvm-svn: 128053

Greg Clayton e996fd30be LLDB now has "Platform" plug-ins. Platform plug-ins are plug-ins that provide
an interface to a local or remote debugging platform. By default each host OS
that supports LLDB should be registering a "default" platform that will be
used unless a new platform is selected. Platforms are responsible for things
such as:
- getting process information by name or by processs ID
- finding platform files. This is useful for remote debugging where there is 
  an SDK with files that might already or need to be cached for debug access.
- getting a list of platform supported architectures in the exact order they
  should be selected. This helps the native x86 platform on MacOSX select the
  correct x86_64/i386 slice from universal binaries.
- Connect to remote platforms for remote debugging
- Resolving an executable including finding an executable inside platform
  specific bundles (macosx uses .app bundles that contain files) and also
  selecting the appropriate slice of universal files for a given platform.

So by default there is always a local platform, but remote platforms can be
connected to. I will soon be adding a new "platform" command that will support
the following commands:
(lldb) platform connect --name machine1 macosx connect://host:port
Connected to "machine1" platform.
(lldb) platform disconnect macosx

This allows LLDB to be well setup to do remote debugging and also once 
connected process listing and finding for things like:
(lldb) process attach --name x<TAB>

The currently selected platform plug-in can now auto complete any available
processes that start with "x". The responsibilities for the platform plug-in
will soon grow and expand.

Greg Clayton 64195a2c8b Abtracted all mach-o and ELF out of ArchSpec. This patch is a modified form
of Stephen Wilson's idea (thanks for the input Stephen!). What I ended up
doing was:
- Got rid of ArchSpec::CPU (which was a generic CPU enumeration that mimics
  the contents of llvm::Triple::ArchType). We now rely upon the llvm::Triple 
  to give us the machine type from llvm::Triple::ArchType.
- There is a new ArchSpec::Core definition which further qualifies the CPU
  core we are dealing with into a single enumeration. If you need support for
  a new Core and want to debug it in LLDB, it must be added to this list. In
  the future we can allow for dynamic core registration, but for now it is
  hard coded.
- The ArchSpec can now be initialized with a llvm::Triple or with a C string
  that represents the triple (it can just be an arch still like "i386").
- The ArchSpec can still initialize itself with a architecture type -- mach-o
  with cpu type and subtype, or ELF with e_machine + e_flags -- and this will
  then get translated into the internal llvm::Triple::ArchSpec + ArchSpec::Core.
  The mach-o cpu type and subtype can be accessed using the getter functions:
  
  uint32_t
  ArchSpec::GetMachOCPUType () const;

  uint32_t
  ArchSpec::GetMachOCPUSubType () const;
  
  But these functions are just converting out internal llvm::Triple::ArchSpec 
  + ArchSpec::Core back into mach-o. Same goes for ELF.

All code has been updated to deal with the changes.

This should abstract us until later when the llvm::TargetSpec stuff gets
finalized and we can then adopt it.

Greg Clayton 2d4edfbc6a Modified all logging calls to hand out shared pointers to make sure we
don't crash if we disable logging when some code already has a copy of the
logger. Prior to this fix, logs were handed out as pointers and if they were
held onto while a log got disabled, then it could cause a crash. Now all logs
are handed out as shared pointers so this problem shouldn't happen anymore.
We are also using our new shared pointers that put the shared pointer count
and the object into the same allocation for a tad better performance.

Greg Clayton 93aa84e83b Modified the lldb_private::TypeList to use a std::multimap for quicker lookup
by type ID (the most common type of type lookup).

Changed the API logging a bit to always show the objects in the OBJECT(POINTER)
format so it will be easy to locate all instances of an object or references
to it when looking at logs.

Caroline Tice 750cd1755d Clean up the API logging code:

      - Put all arguments & their values into log for calls
      - Add 'this' parameter information to function call logging, making it show the appropriate
        internal pointer (this.obj, this.sp, this.ap...)
      - Clean up some return values
      - Remove logging of constructors that construct empty objects
      - Change '==>' to '=>'  for showing result values...
      - Fix various minor bugs
      - Add some protected 'get' functions to help getting the internal pointers for the 'this' arguments...

Caroline Tice ceb6b1393d First pass at adding logging capabilities for the API functions. At the moment
it logs the function calls, their arguments and the return values.  This is not
complete or polished, but I am committing it now, at the request of someone who
really wants to use it, even though it's not really done.  It currently does not
attempt to log all the functions, just the most important ones.  I will be 
making further adjustments to the API logging code over the next few days/weeks.
(Suggestions for improvements are welcome).


Update the Python build scripts to re-build the swig C++ file whenever

Greg Clayton 274060b6f1 Fixed an issue where we were resolving paths when we should have been.
So the issue here was that we have lldb_private::FileSpec that by default was 
always resolving a path when using the:

FileSpec::FileSpec (const char *path);

and in the:

void FileSpec::SetFile(const char *pathname, bool resolve = true);

This isn't what we want in many many cases. One example is you have "/tmp" on
your file system which is really "/private/tmp". You compile code in that
directory and end up with debug info that mentions "/tmp/file.c". Then you 
type:

(lldb) breakpoint set --file file.c --line 5

If your current working directory is "/tmp", then "file.c" would be turned 
into "/private/tmp/file.c" which won't match anything in the debug info.
Also, it should have been just a FileSpec with no directory and a filename
of "file.c" which could (and should) potentially match any instances of "file.c"
in the debug info.

So I removed the constructor that just takes a path:

FileSpec::FileSpec (const char *path); // REMOVED

You must now use the other constructor that has a "bool resolve" parameter that you must always supply:

FileSpec::FileSpec (const char *path, bool resolve);

I also removed the default parameter to SetFile():

void FileSpec::SetFile(const char *pathname, bool resolve);

And fixed all of the code to use the right settings.

Caroline Tice dac97f31a3 Remove all the __repr__ methods from the API/*.h files, and put them
into python-extensions.swig, which gets included into lldb.swig, and

Greg Clayton a701509229 Fixed the way set/show variables were being accessed to being natively
accessed by the objects that own the settings. The previous approach wasn't
very usable and made for a lot of unnecessary code just to access variables
that were already owned by the objects.

While I fixed those things, I saw that CommandObject objects should really
have a reference to their command interpreter so they can access the terminal
with if they want to output usaage. Fixed up all CommandObjects to take
an interpreter and cleaned up the API to not need the interpreter to be
passed in.

Fixed the disassemble command to output the usage if no options are passed
down and arguments are passed (all disassebmle variants take options, there
are no "args only").

Caroline Tice 3df9a8dfd7 This is a very large commit that completely re-does the way lldb
handles user settable internal variables (the equivalent of set/show
variables in gdb).  In addition to the basic infrastructure (most of
which is defined in UserSettingsController.{h,cpp}, there are examples
of two classes that have been set up to contain user settable
variables (the Debugger and Process classes).  The 'settings' command
has been modified to be a command-subcommand structure, and the 'set',
'show' and 'append' commands have been moved into this sub-commabnd
structure.  The old StateVariable class has been completely replaced
by this, and the state variable dictionary has been removed from the
Command Interpreter.  Places that formerly accessed the state variable
mechanism have been modified to access the variables in this new
structure instead (checking the term-width; getting/checking the
prompt; etc.)

Variables are attached to classes; there are two basic "flavors" of
variables that can be set: "global" variables (static/class-wide), and
"instance" variables (one per instance of the class).  The whole thing
has been set up so that any global or instance variable can be set at
any time (e.g. on start up, in your .lldbinit file), whether or not
any instances actually exist (there's a whole pending and default
values mechanism to help deal with that).

Jim Ingham 2976d00adb Change "Current" as in GetCurrentThread, GetCurrentStackFrame, etc, to "Selected" i.e. GetSelectedThread. Selected makes more sense, since these are set by some user action (a selection). I didn't change "CurrentProcess" since this is always controlled by the target, and a given target can only have one process, so it really can't be selected.

Caroline Tice ebc1bb277c Add a unique ID to each debugger instance.
Add functions to look up debugger by id
Add global variable to lldb python module, to hold debugger id
Modify embedded Python interpreter to update the global variable with the
 id of its current debugger.
Modify the char ** typemap definition in lldb.swig to accept 'None' (for NULL)
 as a valid value.

The point of all this is so that, when you drop into the embedded interpreter
from the command interpreter (or when doing Python-based breakpoint commands),
there is a way for the Python side to find/get the correct debugger
instance ( by checking debugger_unique_id, then calling 
SBDebugger::FindDebuggerWithID  on it).

llvm-svn: 107287
2010-06-30 16:22:25 +00:00
Greg Clayton 6611103cfe Very large changes that were needed in order to allow multiple connections
to the debugger from GUI windows. Previously there was one global debugger
instance that could be accessed that had its own command interpreter and
current state (current target/process/thread/frame). When a GUI debugger
was attached, if it opened more than one window that each had a console
window, there were issues where the last one to setup the global debugger
object won and got control of the debugger.

To avoid this we now create instances of the lldb_private::Debugger that each 
has its own state:
- target list for targets the debugger instance owns
- current process/thread/frame
- its own command interpreter
- its own input, output and error file handles to avoid conflicts
- its own input reader stack

So now clients should call:

    SBDebugger::Initialize(); // (static function)

    SBDebugger debugger (SBDebugger::Create());
    // Use which ever file handles you wish
    debugger.SetErrorFileHandle (stderr, false);
    debugger.SetOutputFileHandle (stdout, false);
    debugger.SetInputFileHandle (stdin, true);

    // main loop
    
    SBDebugger::Terminate(); // (static function)
    
SBDebugger::Initialize() and SBDebugger::Terminate() are ref counted to
ensure nothing gets destroyed too early when multiple clients might be
attached.

Cleaned up the command interpreter and the CommandObject and all subclasses
to take more appropriate arguments.
