Greg Clayton 84c39663a9 Added a new OptionValue subclass for lldb::Format: OptionValueFormat. Added
new OptionGroup subclasses for:
- output file for use with options: 
        long opts: --outfile <path> --append--output
        short opts: -o <path> -A
        
- format for use with options:
        long opts: --format <format>

- variable object display controls for depth, pointer depth, wether to show
  types, show summary, show location, flat output, use objc "po" style summary.
  
Modified ValueObjectMemory to be able to be created either with a TypeSP or
a ClangASTType.

Switched "memory read" over to use OptionGroup subclasses: one for the outfile
options, one for the command specific options, and one for the format.

Greg Clayton ab65b34fdc Added auto completion for architecture names and for platforms.
Modified the OptionGroupOptions to be able to specify only some of the options
that should be appended by using the usage_mask in the group defintions and
also provided a way to remap them to a new usage mask after the copy. This 
allows options to be re-used and also targetted for specific option groups.

Modfied the CommandArgumentType to have a new eArgTypePlatform enumeration.
Taught the option parser to be able to automatically use the appropriate
auto completion for a given options if nothing is explicitly specified
in the option definition. So you don't have to specify it in the option
definition tables.

Renamed the default host platform name to "host", and the default platform
hostname to be "localhost".

Modified the "file" and "platform select" commands to make sure all options
and args are good prior to creating a new platform. Also defer the computation
of the architecture in the file command until all options are parsed and the
platform has either not been specified or reset to a new value to avoid
computing the arch more than once.

Switch the PluginManager code over to using llvm::StringRef for string
comparisons and got rid of all the AccessorXXX functions in lieu of the newer
mutex + collection singleton accessors.

Greg Clayton f6b8b58184 Added two new classes for command options:
lldb_private::OptionGroup
    lldb_private::OptionGroupOptions

OptionGroup lets you define a class that encapsulates settings that you want
to reuse in multiple commands. It contains only the option definitions and the
ability to set the option values, but it doesn't directly interface with the
lldb_private::Options class that is the front end to all of the CommandObject
option parsing. For that the OptionGroupOptions class can be used. It aggregates
one or more OptionGroup objects and directs the option setting to the 
appropriate OptionGroup class. For an example of this, take a look at the 
CommandObjectFile and how it uses its "m_option_group" object shown below
to be able to set values in both the FileOptionGroup and PlatformOptionGroup
classes. The members used in CommandObjectFile are:

    OptionGroupOptions m_option_group;
    FileOptionGroup m_file_options;
    PlatformOptionGroup m_platform_options;

Then in the constructor for CommandObjectFile you can combine the option
settings. The code below shows a simplified version of the constructor:

CommandObjectFile::CommandObjectFile(CommandInterpreter &interpreter) :
    CommandObject (...),
    m_option_group (interpreter),
    m_file_options (),
    m_platform_options(true)
{
    m_option_group.Append (&m_file_options);
    m_option_group.Append (&m_platform_options);
    m_option_group.Finalize();
}

We append the m_file_options and then the m_platform_options and then tell
the option group the finalize the results. This allows the m_option_group to
become the organizer of our prefs and after option parsing we end up with
valid preference settings in both the m_file_options and m_platform_options
objects. This also allows any other commands to use the FileOptionGroup and
PlatformOptionGroup classes to implement options for their commands.

Renamed:
    virtual void Options::ResetOptionValues();
to:
    virtual void Options::OptionParsingStarting();

And implemented a new callback named:

    virtual Error Options::OptionParsingFinished();
    
This allows Options subclasses to verify that the options all go together
after all of the options have been specified and gives the chance for the
command object to return an error. It also gives a chance to take all of the
option values and produce or initialize objects after all options have
completed parsing.

Modfied:

    virtual Error
    SetOptionValue (int option_idx, const char *option_arg) = 0;
    
to be:

    virtual Error
    SetOptionValue (uint32_t option_idx, const char *option_arg) = 0;

(option_idx is now unsigned).

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 32e0a7509c Many improvements to the Platform base class and subclasses. The base Platform
class now implements the Host functionality for a lot of things that make 
sense by default so that subclasses can check:

int
PlatformSubclass::Foo ()
{
    if (IsHost())
        return Platform::Foo (); // Let the platform base class do the host specific stuff
    
    // Platform subclass specific code...
    int result = ...
    return result;
}

Added new functions to the platform:

    virtual const char *Platform::GetUserName (uint32_t uid);
    virtual const char *Platform::GetGroupName (uint32_t gid);

The user and group names are cached locally so that remote platforms can avoid
sending packets multiple times to resolve this information.

Added the parent process ID to the ProcessInfo class. 

Added a new ProcessInfoMatch class which helps us to match processes up
and changed the Host layer over to using this new class. The new class allows
us to search for processs:
1 - by name (equal to, starts with, ends with, contains, and regex)
2 - by pid
3 - And further check for parent pid == value, uid == value, gid == value, 
    euid == value, egid == value, arch == value, parent == value.
    
This is all hookup up to the "platform process list" command which required
adding dumping routines to dump process information. If the Host class 
implements the process lookup routines, you can now lists processes on 
your local machine:

machine1.foo.com % lldb
(lldb) platform process list 
PID    PARENT USER       GROUP      EFF USER   EFF GROUP  TRIPLE                   NAME

92742  92710  username   usergroup  username   usergroup  i386-apple-darwin        debugserver


This of course also works remotely with the lldb-platform:

The lldb-platform implements everything with the Host:: layer, so this should
"just work" for linux. I will probably be adding more stuff to the Host layer
for launching processes and attaching to processes so that this support should
eventually just work as well.

Modified the target to be able to be created with an architecture that differs
from the main executable. This is needed for iOS debugging since we can have
an "armv6" binary which can run on an "armv7" machine, so we want to be able
to do:

% lldb
(lldb) platform create remote-ios
(lldb) file --arch armv7 a.out

Where "a.out" is an armv6 executable. The platform then can correctly decide
to open all "armv7" images for all dependent shared libraries.

Modified the disassembly to show the current PC value. Example output:

(lldb) disassemble --frame
a.out`main:
   0x1eb7:  pushl  %ebp
   0x1eb8:  movl   %esp, %ebp
   0x1eba:  pushl  %ebx
   0x1ebb:  subl   $20, %esp
   0x1ebe:  calll  0x1ec3                   ; main + 12 at test.c:18
   0x1ec3:  popl   %ebx
-> 0x1ec4:  calll  0x1f12                   ; getpid
   0x1ec9:  movl   %eax, 4(%esp)
   0x1ecd:  leal   199(%ebx), %eax
   0x1ed3:  movl   %eax, (%esp)
   0x1ed6:  calll  0x1f18                   ; printf
   0x1edb:  leal   213(%ebx), %eax
   0x1ee1:  movl   %eax, (%esp)
   0x1ee4:  calll  0x1f1e                   ; puts
   0x1ee9:  calll  0x1f0c                   ; getchar
   0x1eee:  movl   $20, (%esp)
   0x1ef5:  calll  0x1e6a                   ; sleep_loop at test.c:6
   0x1efa:  movl   $12, %eax
   0x1eff:  addl   $20, %esp
   0x1f02:  popl   %ebx
   0x1f03:  leave
   0x1f04:  ret
   
This can be handy when dealing with the new --line options that was recently
added:

(lldb) disassemble --line
a.out`main + 13 at test.c:19
   18  	{
-> 19  		printf("Process: %i\n\n", getpid());
   20  	    puts("Press any key to continue..."); getchar();
-> 0x1ec4:  calll  0x1f12                   ; getpid
   0x1ec9:  movl   %eax, 4(%esp)
   0x1ecd:  leal   199(%ebx), %eax
   0x1ed3:  movl   %eax, (%esp)
   0x1ed6:  calll  0x1f18                   ; printf

Modified the ModuleList to have a lookup based solely on a UUID. Since the
UUID is typically the MD5 checksum of a binary image, there is no need
to give the path and architecture when searching for a pre-existing
image in an image list.

Now that we support remote debugging a bit better, our lldb_private::Module
needs to be able to track what the original path for file was as the platform
knows it, as well as where the file is locally. The module has the two 
following functions to retrieve both paths:

const FileSpec &Module::GetFileSpec () const;
const FileSpec &Module::GetPlatformFileSpec () const;

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.

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 deaab2220e Modify command options to use the new arguments mechanism. Now all command option
arguments are specified in a standardized way, will have a standardized name, and
have functioning help.

The next step is to start writing useful help for all the argument types.

llvm-svn: 115335
2010-10-01 19:59:14 +00:00
Caroline Tice e139cf2320 Add infrastructure for standardizing arguments for commands and
command options; makes it easier to ensure that the same type of
argument will have the same name everywhere, hooks up help for command
arguments, so that users can ask for help when they are confused about
what an argument should be; puts in the beginnings of the ability to
do tab-completion for certain types of arguments, allows automatic
syntax help generation for commands with arguments, and adds command
arguments into command options help correctly.

Currently only the breakpoint-id and breakpoint-id-range arguments, in
the breakpoint commands, have been hooked up to use the new mechanism.
The next steps will be to fix the command options arguments to use
this mechanism, and to fix the rest of the regular command arguments
to use this mechanism.  Most of the help text is currently missing or
dummy text; this will need to be filled in, and the existing argument
help text will need to be cleaned up a bit (it was thrown in quickly,
mostly for testing purposes).

Help command now works for all argument types, although the help may not
be very helpful yet.

Those commands that take "raw" command strings now indicate it in their
help text.

- Modified the short character for "--ignore-count" options to "-i"

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 f362c45e8d Modify the command options help generation so that required options
are always printed immediately after the command, before optional
options; also so that in the detailed descriptions of each command
option, the options and their help are output in alphabetical order
(sorted by the short option) rather in whatever order they happened to
be in the table.

the default variables.

2010-09-09 06:25:08 +00:00
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.

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.
