Jason Molenda 64de91522f Code reorganization in PlatformDarwin for how the libdispatch
offsets structure is read & saved in the platform object -- soon
we'll be getting more than the queue name offset out of this
structure so we'll need to reuse the information in other methods.

Greg Clayton 5fb8f79738 Fixed internal code to not link against and code from "lldb/API/*".
lldb_private::Debugger was #including some "lldb/API" header files which causes tools (lldb-platform and lldb-gdbserver) that link against the internals only (no API layer) to fail to link depending on which calls were being used.

Also fixed the current working directory so that it gets set correctly for remote test suite runs. Now the remote working directory is set to: "ARCH/TESTNUM/..." where ARCH is the current architecture name and "TESTNUM" is the current test number. 

Fixed the "lldb-platform" and "lldb-gdbserver" to not warn about mismatched visibility settings by having each have their own exports file which contains nothing. This forces all symbols to not be exported, and also quiets the linker warnings.

Greg Clayton fbb7634934 Expose SBPlatform through the public API.
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.

Greg Clayton eb023e75dc <rdar://problem/13635174>
Added a way to set hardware breakpoints from the "breakpoint set" command with the new "--hardware" option. Hardware breakpoints are not a request, they currently are a requirement. So when breakpoints are specified as hardware breakpoints, they might fail to be set when they are able to be resolved and should be used sparingly. This is currently hooked up for GDB remote debugging. 

Linux and FreeBSD should quickly enable this feature if possible, or return an error for any breakpoints that are hardware breakpoint sites in the "virtual Error Process::EnableBreakpointSite (BreakpointSite *bp_site);" function.

Jim Ingham d39907935c Turns out the number of times you need to resume the process for /bin/sh depends on the
setting of the environment variable COMMAND_MODE.  Changed the Platform::GetResumeCountForShell
to Platform::GetResumeCountForLaunchInfo, and check both the shell and in the case of
/bin/sh the environment as well.

Jim Ingham df0ae22f92 Changing the default shell to /bin/sh brought up a long-standing bug on OS X,
that /bin/sh re-exec's itself to /bin/bash, so it needs one more resume when you
are using it as the shell than /bin/bash did or you will stop at the start of your
program, rather than running it.

So I added a Platform API to get the number of resumes needed when launching with
a particular shell, and set the right values for Mac OS X.

Daniel Malea e0f8f574c7 merge lldb-platform-work branch (and assorted fixes) into trunk
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'

<rdar://problem/13594769>

Main changes in this patch include:
- cleanup plug-in interface and use ConstStrings for plug-in names
- Modfiied the BSD Archive plug-in to be able to pick out the correct .o file when .a files contain multiple .o files with the same name by using the timestamp
- Modified SymbolFileDWARFDebugMap to properly verify the timestamp on .o files it loads to ensure we don't load updated .o files and cause problems when debugging

The plug-in interface changes:

Modified the lldb_private::PluginInterface class that all plug-ins inherit from:

Changed:

virtual const char * GetPluginName() = 0;

To: 

virtual ConstString GetPluginName() = 0;

Removed:

virtual const char * GetShortPluginName() = 0;

- Fixed up all plug-in to adhere to the new interface and to return lldb_private::ConstString values for the plug-in names. 
- Fixed all plug-ins to return simple names with no prefixes. Some plug-ins had prefixes and most ones didn't, so now they all don't have prefixed names, just simple names like "linux", "gdb-remote", etc.

Greg Clayton b5ad4ec7a3 Cleanup logging to use the new "std::string FileSpec::GetPath()" function. Also added a similar function for modules:
std::string
Module::GetSpecificationDescription () const;

This returns the module as "/usr/lib/libfoo.dylib" for normal files (calls "std::string FileSpec::GetPath()" on m_file) but it also might include the object name in case the module is for a .o file in a BSD archive ("/usr/lib/libfoo.a(bar.o)"). Cleaned up necessary logging code to use it.

Greg Clayton 91c0e749e3 <rdar://problem/12973809>
Fixed an issue with the auto loading of script resources in debug info files. Any platform can add support for this, and on MacOSX we allow dSYM files to contain python modules that get automatically loaded when a dSYM file is associated with an executable or shared library. 

The modifications will now:
- Let the module locate the symbol file naturally instead of using a function that only works in certain cases. This helps us to locate the script resources as long as the dSYM file can be found.
- Don't try and do any of this if the script interpreter has scripting disabled.
- Allow more than one scripting resource to be found in a symbol file by returning the list
- Load the scripting resources when a symbol file is added via the "target symbols add" command.
- Be smarter about matching the dSYM mach-o file to an existing executable in the target images by stripping extensions on the symfile basname if needed.

Enrico Granata 1759848be0 <rdar://problem/12586350>
This commit does three things:
(a) introduces a new notification model for adding/removing/changing modules to a ModuleList, and applies it to the Target's ModuleList, so that we make sure to always trigger the right set of actions
whenever modules come and go in a target. Certain spots in the code still need to "manually" notify the Target for several reasons, so this is a work in progress
(b) adds a new capability to the Platforms: locating a scripting resources associated to a module. A scripting resource is a Python file that can load commands, formatters, ... and any other action
of interest corresponding to the loading of a module. At the moment, this is only implemented on Mac OS X and only for files inside .dSYM bundles - the next step is going to be letting
the frameworks themselves hold their scripting resources. Implementors of platforms for other systems are free to implement "the right thing" for their own worlds
(c) hooking up items (a) and (b) so that targets auto-load the scripting resources as the corresponding modules get loaded in a target. This has a few caveats at the moment:
 - the user needs to manually add the .py file to the dSYM (soon, it will also work in the framework itself)
 - if two modules with the same name show up during the lifetime of an LLDB session, the second one won't be able to load its scripting resource, but will otherwise work just fine

<rdar://problem/12068650>

More fixes to how we handle paths that are used to create a target.

This modification centralizes the location where and how what the user specifies gets resolved. Prior to this fix, the TargetList::CreateTarget variants took a FileSpec object which meant everyone had the opportunity to resolve the path their own way. Now both CreateTarget variants take a "const char *use_exe_path" which allows the TargetList::CreateTarget to centralize where the resolving happens and "do the right thing".

Greg Clayton 1f7460716b <rdar://problem/11757916>
Make breakpoint setting by file and line much more efficient by only looking for inlined breakpoint locations if we are setting a breakpoint in anything but a source implementation file. Implementing this complex for a many reasons. Turns out that parsing compile units lazily had some issues with respect to how we need to do things with DWARF in .o files. So the fixes in the checkin for this makes these changes:
- Add a new setting called "target.inline-breakpoint-strategy" which can be set to "never", "always", or "headers". "never" will never try and set any inlined breakpoints (fastest). "always" always looks for inlined breakpoint locations (slowest, but most accurate). "headers", which is the default setting, will only look for inlined breakpoint locations if the breakpoint is set in what are consudered to be header files, which is realy defined as "not in an implementation source file". 
- modify the breakpoint setting by file and line to check the current "target.inline-breakpoint-strategy" setting and act accordingly
- Modify compile units to be able to get their language and other info lazily. This allows us to create compile units from the debug map and not have to fill all of the details in, and then lazily discover this information as we go on debuggging. This is needed to avoid parsing all .o files when setting breakpoints in implementation only files (no inlines). Otherwise we would need to parse the .o file, the object file (mach-o in our case) and the symbol file (DWARF in the object file) just to see what the compile unit was.
- modify the "SymbolFileDWARFDebugMap" to subclass lldb_private::Module so that the virtual "GetObjectFile()" and "GetSymbolVendor()" functions can be intercepted when the .o file contenst are later lazilly needed. Prior to this fix, when we first instantiated the "SymbolFileDWARFDebugMap" class, we would also make modules, object files and symbol files for every .o file in the debug map because we needed to fix up the sections in the .o files with information that is in the executable debug map. Now we lazily do this in the DebugMapModule::GetObjectFile()

Cleaned up header includes a bit as well.

Greg Clayton 67cc06366c Reimplemented the code that backed the "settings" in lldb. There were many issues with the previous implementation:
- no setting auto completion
- very manual and error prone way of getting/setting variables
- tons of code duplication
- useless instance names for processes, threads

Now settings can easily be defined like option values. The new settings makes use of the "OptionValue" classes so we can re-use the option value code that we use to set settings in command options. No more instances, just "does the right thing".

Fixed type lookups to "do the right thing". Prior to this fix, looking up a type using "foo::bar" would result in a type list that contains all types that had "bar" as a basename unless the symbol file was able to match fully qualified names (which our DWARF parser does not). 

This fix will allow type matches to be made based on the basename and then have the types that don't match filtered out. Types by name can be fully qualified, or partially qualified with the new "bool exact_match" parameter to the Module::FindTypes() method.

This fixes some issue that we discovered with dynamic type resolution as well as improves the overall type lookups in LLDB.

Greg Clayton b9a01b3990 Made a ModuleSpec class in Module.h which can specify a module using one or
more of the local path, platform path, associated symbol file, UUID, arch,
object name and object offset. This allows many of the calls that were
GetSharedModule to reduce the number of arguments that were used in a call
to these functions. It also allows a module to be created with a ModuleSpec
which allows many things to be specified prior to any accessors being called
on the Module class itself. 

I was running into problems when adding support for "target symbol add"
where you can specify a stand alone debug info file after debugging has started
where I needed to specify the associated symbol file path and if I waited until
after construction, the wrong  symbol file had already been located. By using
the ModuleSpec it allows us to construct a module with as little or as much
information as needed and not have to change the parameter list.

Greg Clayton c859e2d524 Full core file support has been added for mach-o core files.
Tracking modules down when you have a UUID and a path has been improved.

DynamicLoaderDarwinKernel no longer parses mach-o load commands and it
now uses the memory based modules now that we can load modules from memory.

Added a target setting named "target.exec-search-paths" which can be used
to supply a list of directories to use when trying to look for executables.
This allows one or more directories to be used when searching for modules
that may not exist in the SDK/PDK. The target automatically adds the directory
for the main executable to this list so this should help us in tracking down
shared libraries and other binaries.

Greg Clayton c3776bf288 First pass at mach-o core file support is in. It currently works for x86_64
user space programs. The core file support is implemented by making a process
plug-in that will dress up the threads and stack frames by using the core file
memory. 

Added many default implementations for the lldb_private::Process functions so
that plug-ins like the ProcessMachCore don't need to override many many 
functions only to have to return an error.

Added new virtual functions to the ObjectFile class for extracting the frozen
thread states that might be stored in object files. The default implementations
return no thread information, but any platforms that support core files that
contain frozen thread states (like mach-o) can make a module using the core
file and then extract the information. The object files can enumerate the 
threads and also provide the register state for each thread. Since each object
file knows how the thread registers are stored, they are responsible for 
creating a suitable register context that can be used by the core file threads.

Changed the process CreateInstace callbacks to return a shared pointer and
to also take an "const FileSpec *core_file" parameter to allow for core file
support. This will also allow for lldb_private::Process subclasses to be made
that could load crash logs. This should be possible on darwin where the crash
logs contain all of the stack frames for all of the threads, yet the crash
logs only contain the registers for the crashed thrad. It should also allow
some variables to be viewed for the thread that crashed.

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 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.
