Greg Clayton 144f3a9c90 Added a new class to Process.h: ProcessAttachInfo. This class contains enough
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.

Greg Clayton da7bc7d000 <rdar://problem/10126482>
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.

Greg Clayton c9ed478a39 Added the ability to run a process in a shell on MacOSX currently when using
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.

Greg Clayton f49e65ae7c Made the Host::SetCrashDescription(const char *) function copy the incoming

Greg Clayton dce502ede0 Fixed the Xcode project building of LLVM to be a bit more user friendly:
- 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.

Greg Clayton 982c9762a2 Modified all Process::Launch() calls to use a ProcessLaunchInfo structure
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.

Greg Clayton 86edbf41d1 Cleaned up many error codes. For any who is filling in error strings into
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.

Greg Clayton 81c22f6104 Moved lldb::user_id_t values to be 64 bit. This was going to be needed for
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.

Enrico Granata a9dbf4325e this patch introduces a new command script import command which takes as input a filename for a Python script and imports the module contained in that file. the containing directory is added to the Python path such that dependencies are honored. also, the module may contain an __lldb_init_module(debugger,dict) function, which gets called after importing, and which can somehow initialize the module's interaction with lldb

Johnny Chen 16dcf718d3 Add a commnad to set a condition for a watchpoint. Example:
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.

2011-10-14 01:16:39 +00:00
Johnny Chen 01a678603a SBValue::Watch() and SBValue::WatchPointee() are now the official API for creating
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.

Greg Clayton 1ed54f50c5 Cleaned up the the code that figures out the inlined stack frames given a
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.

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.

Greg Clayton 8f7180b11e Added more functionality to the public API to allow for better
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
2011-09-26 07:11:27 +00:00
Greg Clayton d9dc52dc4c Added the ability to get all section contents, or the section
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.

Jim Ingham 810bf85e8a Add GetAddress to SBBreakpointLocation, and put the .i files in the API section of the Xcode project.
llvm-svn: 140440
2011-09-24 01:04:57 +00:00
Greg Clayton cac9c5f971 Added to the public API to allow symbolication:
- 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
2011-09-24 00:52:29 +00:00
Johnny Chen 6027c94d2f Add an SB API SBFrame::WatchValue() and exported to the Python interface to
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.

Greg Clayton c14ee32db5 Converted the lldb_private::Process over to use the intrusive
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.

Sean Callanan 0886e5657b Fixed a problem with the IR interpreter that caused
it to generate result variables that were not bound
to their underlying data.  This allowed the SBValue
class to use the interpreter (if possible).

Also made sure that any result variables that point
to stack allocations in the stack frame of the
interpreted expressions do not get live data.

Jason Molenda fd54b368ea Update declarations for all functions/methods that accept printf-style

llvm-svn: 140185
2011-09-20 21:44:10 +00:00
Greg Clayton 762f7135e2 Don't put modules for .o files into the global shared module list. We
used to do this because we needed to find the shared pointer for a .o
file when the .o file's module was needed in a SymbolContext since the
module in a symbol context was a shared pointer. Now that we are using
intrusive pointers we don't have this limitation anymore since any
instrusive shared pointer can be made from a pointer to an object
all on its own.

Also switched over to having the Module and SymbolVendor use shared 
pointers to their object files as had a leak on MacOSX when the 
SymbolVendor's object file wasn't the same as the Module's (debug info
in a stand along file (dSYM file)). Now everything will correctly clean
itself up when the module goes away after an executable gets rebuilt.

Now we correctly get rid of .o files that are used with the DWARF with 
debug map executables on subsequent runs since the only shared pointer
to the object files in from the DWARF symbol file debug map parser, and
when the module gets replaced, it destroys to old one along with all .o 
files. 

Also added a small optimization when using BSD archives where we will
remove old BSD containers from the shared list when they are outdated.

2011-09-18 18:59:15 +00:00
Greg Clayton a2eee184e0 Removed the function:
ModuleSP
	Module::GetSP();

Since we are now using intrusive ref counts, we can easily turn any
pointer to a module into a shared pointer just by assigning it.

Sean Callanan 3bfdaa2a47 This patch modifies the expression parser to allow it
to execute expressions even in the absence of a process.
This allows expressions to run in situations where the
target cannot run -- e.g., to perform calculations based
on type information, or to inspect a binary's static
data.

This modification touches the following files:

lldb-private-enumerations.h
  Introduce a new enum specifying the policy for
  processing an expression.  Some expressions should
  always be JITted, for example if they are functions
  that will be used over and over again.  Some
  expressions should always be interpreted, for
  example if the target is unsafe to run.  For most,
  it is acceptable to JIT them, but interpretation
  is preferable when possible.

Target.[h,cpp]
  Have EvaluateExpression now accept the new enum.

ClangExpressionDeclMap.[cpp,h]
  Add support for the IR interpreter and also make
  the ClangExpressionDeclMap more robust in the 
  absence of a process.

ClangFunction.[cpp,h]
  Add support for the new enum.

IRInterpreter.[cpp,h]
  New implementation.

ClangUserExpression.[cpp,h]
  Add support for the new enum, and for running 
  expressions in the absence of a process.

ClangExpression.h
  Remove references to the old DWARF-based method
  of evaluating expressions, because it has been
  superseded for now.

ClangUtilityFunction.[cpp,h]
  Add support for the new enum.

ClangExpressionParser.[cpp,h]
  Add support for the new enum, remove references
  to DWARF, and add support for checking whether
  the expression could be evaluated statically.

IRForTarget.[h,cpp]
  Add support for the new enum, and add utility
  functions to support the interpreter.

IRToDWARF.cpp
  Removed

CommandObjectExpression.cpp
  Remove references to the obsolete -i option.

Process.cpp 
  Modify calls to ClangUserExpression::Evaluate
  to pass the correct enum (for dlopen/dlclose)

SBValue.cpp
  Add support for the new enum.

SBFrame.cpp
  Add support for he new enum.

BreakpointOptions.cpp
  Add support for the new enum.

Jim Ingham e37d605e7d SBSourceManager now gets the real source manager either from the Debugger or Target. Also, move the SourceManager file cache into the debugger
so it can be shared amongst the targets.

2011-09-13 00:29:56 +00:00
Greg Clayton bf2331c491 Added the ability to introspect types thourgh the public SBType interface.
Fixed up many API calls to not be "const" as const doesn't mean anything to
most of our lldb::SB objects since they contain a shared pointer, auto_ptr, or
pointer to the types which circumvent the constness anyway.

llvm-svn: 139428
2011-09-09 23:04:00 +00:00
Jim Ingham b7f6b2fa3c Move the SourceManager from the Debugger to the Target. That way it can store the per-Target default Source File & Line.
Set the default Source File & line to main (if it can be found.) at startup.  Selecting the current thread & or frame resets 
the current source file & line, and "source list" as well as the breakpoint command "break set -l <NUM>" will use the 
current source file.
