N streams by making the stream a vector of stream shared pointers
that is protected by a mutex. Streams can be get/set by index which
allows indexes to be defined as stream indentifiers. If a stream is
set at index 3 and there are now streams in the collection, then
empty stream objects are inserted to ensure that stream at index 3
has a valid stream. There is also an append method that allows a stream
to be pushed onto the stack. This will allow our streams to be very
flexible in where the output goes.
Modified the CommandReturnObject to use the new StreamTee functionality.
This class now defines two StreamTee indexes: 0 for the stream string
stream, and 1 for the immediate stream. This is used both on the output
and error streams.
Added the ability to get argument types as strings or as descriptions.
This is exported through the SBCommandInterpreter API to allow external
access.
Modified the Driver class to use the newly exported argument names from
SBCommandInterpreter::GetArgumentTypeAsCString().
llvm-svn: 126067
a Stream, and then added GetOutputData & GetErrorData to get the accumulated data.
- Added a StreamTee that will tee output to two provided lldb::StreamSP's.
- Made the CommandObjectReturn use this so you can Tee the results immediately to
the debuggers output file, as well as saving up the results to return when the command
is done executing.
- HandleCommands now uses this so that if you have a set of commands that continue the target
you will see the commands come out as they are processed.
- The Driver now uses this to output the command results as you go, which makes the interface
more reactive seeming.
llvm-svn: 126015
Targets can now specify some additional parameters for when we debug
executables that can help with plug-in selection:
target.execution-level = auto | user | kernel
target.execution-mode = auto | dynamic | static
target.execution-os-type = auto | none | halted | live
On some systems, the binaries that are created are the same wether you use
them to debug a kernel, or a user space program. Many times inspecting an
object file can reveal what an executable should be. For these cases we can
now be a little more complete by specifying wether to detect all of these
things automatically (inspect the main executable file and select a plug-in
accordingly), or manually to force the selection of certain plug-ins.
To do this we now allow the specficifation of wether one is debugging a user
space program (target.execution-level = user) or a kernel program
(target.execution-level = kernel).
We can also specify if we want to debug a program where shared libraries
are dynamically loaded using a DynamicLoader plug-in
(target.execution-mode = dynamic), or wether we will treat all symbol files
as already linked at the correct address (target.execution-mode = static).
We can also specify if the inferior we are debugging is being debugged on
a bare board (target.execution-os-type = none), or debugging an OS where
we have a JTAG or other direct connection to the inferior stops the entire
OS (target.execution-os-type = halted), or if we are debugging a program on
something that has live debug services (target.execution-os-type = live).
For the "target.execution-os-type = halted" mode, we will need to create
ProcessHelper plug-ins that allow us to extract the process/thread and other
OS information by reading/writing memory.
This should allow LLDB to be used for a wide variety of debugging tasks and
handle them all correctly.

where the implementation is hidden in the host layer. This avoids
a slew of "#if LLDB_CONFIG_TERMIOS_SUPPORTED" statements in the
code and keeps things cleaner.
llvm-svn: 125057
#include "lldb/Host/Config.h"
Or the LLDB_CONFIG_TERMIOS_SUPPORTED defined won't be set. I will fix all
of this Termios stuff later today by moving lldb/Core/TTYState.* into the
host layer and then we conditionalize all of this inside TTYState.cpp and
then we get rid of LLDB_CONFIG_TERMIOS_SUPPORTED all together.
Typically, when we start to see too many "#if LLDB_CONFIG_XXXX" preprocessor
directives, this is a good indicator that something needs to be moved over to
the host layer. TTYState can be modified to do all of the things that many
areas of the code are currently doing, and it will avoid all of the
preprocessor noise.
llvm-svn: 125027
(lldb) process connect <remote-url>
Currently when you specify a file with the file command it helps us to find
a process plug-in that is suitable for debugging. If you specify a file you
can rely upon this to find the correct debugger plug-in:
% lldb a.out
Current executable set to 'a.out' (x86_64).
(lldb) process connect connect://localhost:2345
...
If you don't specify a file, you will need to specify the plug-in name that
you wish to use:
% lldb
(lldb) process connect --plugin process.gdb-remote connect://localhost:2345
Other connection URL examples:
(lldb) process connect connect://localhost:2345
(lldb) process connect tcp://127.0.0.1
(lldb) process connect file:///dev/ttyS1
We are currently treating the "connect://host:port" as a way to do raw socket
connections. If there is a URL for this already, please let me know and we
will adopt it.
So now you can connect to a remote debug server with the ProcessGDBRemote
plug-in. After connection, it will ask for the pid info using the "qC" packet
and if it responds with a valid process ID, it will be equivalent to attaching.
If it response with an error or invalid process ID, the LLDB process will be
in a new state: eStateConnected. This allows us to then download a program or
specify the program to run (using the 'A' packet), or specify a process to
attach to (using the "vAttach" packets), or query info about the processes
that might be available.
llvm-svn: 124846
extra launch options:
LLDB_LAUNCH_FLAG_DISABLE_ASLR disables ASLR for all launched processes
LLDB_LAUNCH_FLAG_DISABLE_STDIO will disable STDIO (reroute to "/dev/null")

LLDB_LAUNCH_FLAG_LAUNCH_IN_TTY will force all launched processes to be
launched in new terminal windows.
Also, don't init python if we never create a script interpreter.

allowing timeouts & informing the user when the lock is unavailable.
Fixed problem where Debugger::Terminate was clearing the debugger list
even when the global ref count was greater than zero.
llvm-svn: 123674
the way LLDB lazily gets complete definitions for types within the debug info.
When we run across a class/struct/union definition in the DWARF, we will only
parse the full definition if we need to. This works fine for top level types
that are assigned directly to variables and arguments, but when we have a
variable with a class, lets say "A" for this example, that has a member:
"B *m_b". Initially we don't need to hunt down a definition for this class
unless we are ever asked to do something with it ("expr m_b->getDecl()" for
example). With my previous approach to lazy type completion, we would be able
to take a "A *a" and get a complete type for it, but we wouldn't be able to
then do an "a->m_b->getDecl()" unless we always expanded all types within a
class prior to handing out the type. Expanding everything is very costly and
it would be great if there were a better way.
A few months ago I worked with the llvm/clang folks to have the
ExternalASTSource class be able to complete classes if there weren't completed
yet:
class ExternalASTSource {
....
virtual void
CompleteType (clang::TagDecl *Tag);
virtual void
CompleteType (clang::ObjCInterfaceDecl *Class);
};
This was great, because we can now have the class that is producing the AST
(SymbolFileDWARF and SymbolFileDWARFDebugMap) sign up as external AST sources
and the object that creates the forward declaration types can now also
complete them anywhere within the clang type system.
This patch makes a few major changes:
- lldb_private::Module classes now own the AST context. Previously the TypeList
objects did.
- The DWARF parsers now sign up as an external AST sources so they can complete
types.
- All of the pure clang type system wrapper code we have in LLDB (ClangASTContext,
ClangASTType, and more) can now be iterating through children of any type,
and if a class/union/struct type (clang::RecordType or ObjC interface)
is found that is incomplete, we can ask the AST to get the definition.
- The SymbolFileDWARFDebugMap class now will create and use a single AST that
all child SymbolFileDWARF classes will share (much like what happens when
we have a complete linked DWARF for an executable).
We will need to modify some of the ClangUserExpression code to take more
advantage of this completion ability in the near future. Meanwhile we should
be better off now that we can be accessing any children of variables through
pointers and always be able to resolve the clang type if needed.

when handling one-liner commands that contain escaped characters. In
order to deal with the new namespace/dictionary stuff, the command was
being embedded within a second string, which messed up the escaping.
This fixes the problem by handling one-liners in a different manner, so they
no longer need to be embedded within another string, and can still be
processed in the proper namespace/dictionary context.
llvm-svn: 123467
exist within the same process (one script interpreter object per debugger object). The
python script interpreter objects are all using the same global Python script interpreter;
they use separate dictionaries to keep their data separate, and mutex's to prevent any object
attempting to use the global Python interpreter when another object is already using it.
llvm-svn: 123415
a shell would interpret it. A few examples that we now handle correctly
INPUT: "Hello "world
OUTPUT: "Hello World"
INPUT: "Hello "' World'
OUTPUT: "Hello World"
INPUT: Hello" World"
OUTPUT: "Hello World"
This broke the setting of dictionary values for the "settings set" command
for things like:
(lldb) settings set target.process.env-vars ["MY_ENV_VAR"]=YES
since we would drop the quotes. I fixed the user settings controller to use
a regular expression so it can accept any of the following inputs for
dictionary setting:
settings set target.process.env-vars ["MY_ENV_VAR"]=YES
settings set target.process.env-vars [MY_ENV_VAR]=YES
settings set target.process.env-vars MY_ENV_VAR=YES
We might want to eventually drop the first two syntaxes, but I won't make
that decision right now.
This allows more natural setting of the envirorment variables:
settings set target.process.env-vars MY_ENV_VAR=YES ABC=DEF CWD=/tmp

- Added new utility function to Arg, GetQuotedCommandString, which re-assembles
the args into a string, replacing quotes that were originally there.
- Modified user settings stuff to always show individual elements when printing out
arrays and dictionaries.
- Added more extensive help to 'settings set', explaining more about dictionaries
and arrays (including current dictionary syntax).
- Fixed bug in user settings where quotes were being stripped and lost, so that
sometimes array or dictionary elements that ought to have been a single element
were being split up.

not the command should take raw input, then handle & dispatch the arguments appropriately.
Also change the 'alias' command to be a command that takes raw input. This is necessary to
allow aliases to be created for other commands that take raw input and might want to include
raw input in the alias itself.
Fix a bug in the aliasing mechanism when creating aliases for commands with 3-or-more words.
Raw input should now be properly handled by all the command and alias mechanisms.
llvm-svn: 121423
- Add logging for command resolution ('log enable lldb commands')
- Fix alias resolution to properly handle commands that take raw input (resolve the alias, but
don't muck up the raw arguments).
Net result: Among other things, 'expr' command can now take strings with escaped characters and
not have the command handling & alias resolution code muck up the escaped characters. E.g.
'expr printf ("\n\n\tHello there!")' should now work properly.
Not working yet: Creating aliases with raw input for commands that take raw input. Working on that.
e.g. 'command alias print_hi expr printf ("\n\tHi!")' does not work yet.
llvm-svn: 121171
comes from by using a virtual function to provide it from the Module's
SymbolVendor by default. This allows the DWARF parser, when being used to
parse DWARF in .o files with a parent DWARF + debug map parser, to get its
type list from the DWARF + debug map parser so when we go and find full
definitions for types (that might come from other .o files), we can use the
type list from the debug map parser. Otherwise we ended up mixing clang types
from one .o file (say a const pointer to a forward declaration "class A") with
the a full type from another .o file. This causes expression parsing, when
copying the clang types from those parsed by the DWARF parser into the
expression AST, to fail -- for good reason. Now all types are created in the
same list.
Also added host support for crash description strings that can be set before
doing a piece of work. On MacOSX, this ties in with CrashReporter support
that allows a string to be dispalyed when the app crashes and allows
LLDB.framework to print a description string in the crash log. Right now this
is hookup up the the CommandInterpreter::HandleCommand() where each command
notes that it is about to be executed, so if we crash while trying to do this
command, we should be able to see the command that caused LLDB to exit. For
all other platforms, this is a nop.

all of the calls inlined in the header file for better performance.
Fixed the summary for C string types (array of chars (with any combo if
modifiers), and pointers to chars) work in all cases.
Fixed an issue where a forward declaration to a clang type could cause itself
to resolve itself more than once if, during the resolving of the type itself
it caused something to try and resolve itself again. We now remove the clang
type from the forward declaration map in the DWARF parser when we start to
resolve it and avoid this additional call. This should stop any duplicate
members from appearing and throwing all the alignment of structs, unions and
classes.

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

making further adjustments to the API logging code over the next few days/weeks.

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.
llvm-svn: 116944
static bool
Host::GetLLDBPath (lldb::PathType path_type, FileSpec &file_spec);
This will fill in "file_spec" with an appropriate path that is appropriate
for the current Host OS. MacOSX will return paths within the LLDB.framework,
and other unixes will return the paths they want. The current PathType
enums are:
typedef enum PathType
{
ePathTypeLLDBShlibDir, // The directory where the lldb.so (unix) or LLDB mach-o file in LLDB.framework (MacOSX) exists
ePathTypeSupportExecutableDir, // Find LLDB support executable directory (debugserver, etc)
ePathTypeHeaderDir, // Find LLDB header file directory
ePathTypePythonDir // Find Python modules (PYTHONPATH) directory
} PathType;
All places that were finding executables are and python paths are now updated
to use this Host call.
Added another new host call to launch the inferior in a terminal. This ability
will be very host specific and doesn't need to be supported on all systems.
MacOSX currently will create a new .command file and tell Terminal.app to open
the .command file. It also uses the new "darwin-debug" app which is a small
app that uses posix to exec (no fork) and stop at the entry point of the
program. The GDB remote plug-in is almost able launch a process and attach to
it, it currently will spawn the process, but it won't attach to it just yet.
This will let LLDB not have to share the terminal with another process and a
new terminal window will pop up when you launch. This won't get hooked up
until we work out all of the kinks. The new Host function is:
static lldb::pid_t
Host::LaunchInNewTerminal (
const char **argv, // argv[0] is executable
const char **envp,
const ArchSpec *arch_spec,
bool stop_at_entry,
bool disable_aslr);
Cleaned up FileSpec::GetPath to not use strncpy() as it was always zero
filling the entire path buffer.
Fixed an issue with the dynamic checker function where I missed a '$' prefix
that should have been added.

and 'process handle'. The test suite would like to control the asynch/sync
execution of the interpreter during the middle of the test method, so the
CommandInterpreter::SetSynchronous(bool value) is modified to allow the mode to

In practice, it would be advisable to control the process and to set the
async/sync mode from a single thread, too.

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.

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

following session shows the user entering the following commands:
1) command source .lldb (set up executable, breakpoint, and breakpoint command)
2) run (the callback mechanism will skip two breakpoints where c()'s immeidate caller is not a())

llvm-svn: 113474
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).

The goal is to separate the parser's data from the data
belonging to the parser's clients. This allows clients
to use the parser to obtain (for example) a JIT compiled
function or some DWARF code, and then discard the parser
state.
Previously, parser state was held in ClangExpression and
used liberally by ClangFunction, which inherited from
ClangExpression. The main effects of this refactoring
are:
- reducing ClangExpression to an abstract class that
declares methods that any client must expose to the
expression parser,
- moving the code specific to implementing the "expr"
command from ClangExpression and
CommandObjectExpression into ClangUserExpression,
a new class,
- moving the common parser interaction code from
ClangExpression into ClangExpressionParser, a new
class, and
- making ClangFunction rely only on
ClangExpressionParser and not depend on the
internal implementation of ClangExpression.
Side effects include:
- the compiler interaction code has been factored
out of ClangFunction and is now in an AST pass
(ASTStructExtractor),
- the header file for ClangFunction is now fully
documented,
- several bugs that only popped up when Clang was
deallocated (which never happened, since the
lifetime of the compiler was essentially infinite)
are now fixed, and
- the developer-only "call" command has been
disabled.
I have tested the expr command and the Objective-C
step-into code, which use ClangUserExpression and
ClangFunction, respectively, and verified that they
work. Please let me know if you encounter bugs or
poor documentation.

Change the prototype of ScriptInterpreter::ExecuteOneLine() to return bool
instead of void and take one additional parameter as CommandReturnObject *.
Propagate the status of one-liner execution back appropriately.

Makefile patch to explicitly use PROJ_SRC_DIR when required. It fixes
build when obj dir is not source dir.
I also fixed a build warning in ClangResultSynthesizer.cpp.

enabled LLVM make style building and made this compile LLDB on Mac OS X. We
can now iterate on this to make the build work on both linux and macosx.

Move the "source", "alias", and "unalias" commands to "commands *".
Move "source-file" to "source list".
Added a "source info" command but it isn't implemented yet.

instead of the last history item to provide a command for the "empty" command.
Use this in the source-file command to make <RETURN> continue the listing rather
than relist the first listing...

interface so everybody does it the same way. Add an "exact" lookup for internal uses.
Fix up a few little cases where we weren't reporting command lookup errors correctly.
Added "b" as an alias for "breakpoint" so it doesn't collide with "bt".

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).

Add a way for the completers to say whether the completed argument should have a space inserted after is
or not.
Added the file name completer to the "file" command.

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.

The top of the header file seems to indicate that this was
intended to be over at include/lldb/Core but we should be in line
with the .cpp file's location so it's include/lldb/Utility for now.
