Committing type format code for Enrico Granata. This commit adds a new top level command named "type". Currently this command implements three commands: type format add <format> <typename1> [<typename2> ...] type format delete <typename1> [<typename2> ...] type format list [<typename1> [<typename2>] ...] This allows you to specify the default format that will be used to display types when you use "frame variable" or "expression", or the SBValue classes. Examples: // Format uint*_t as hex type format add x uint16_t uint32_t uint64_t // Format intptr_t as a pointer type format add p intptr_t The format characters are the same as "printf" for the most part with many additions. These format character specifiers are also used in many other commands ("frame variable" for one). The current list of format characters include: a - char buffer b - binary B - boolean c - char C - printable char d - signed decimal e - float f - float g - float i - signed decimal I - complex integer o - octal O - OSType p - pointer s - c-string u - unsigned decimal x - hex X - complex float y - bytes Y - bytes with ASCII llvm-svn: 133728

Added more platform support. There are now some new commands: platform status -- gets status information for the selected platform platform create <platform-name> -- creates a new instance of a remote platform platform list -- list all available platforms platform select -- select a platform instance as the current platform (not working yet) When using "platform create" it will create a remote platform and make it the selected platform. For instances for iPhone OS debugging on Mac OS X one can do: (lldb) platform create remote-ios --sdk-version=4.0 Remote platform: iOS platform SDK version: 4.0 SDK path: "/Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.0" Not connected to a remote device. (lldb) file ~/Documents/a.out Current executable set to '~/Documents/a.out' (armv6). (lldb) image list [ 0] /Volumes/work/gclayton/Documents/devb/attach/a.out [ 1] /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.0/Symbols/usr/lib/dyld [ 2] /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.0/Symbols/usr/lib/libSystem.B.dylib Note that this is all happening prior to running _or_ connecting to a remote platform. Once connected to a remote platform the OS version might change which means we will need to update our dependecies. Also once we run, we will need to match up the actualy binaries with the actualy UUID's to files in the SDK, or download and cache them locally. This is just the start of the remote platforms, but this modification is the first iteration in getting the platforms really doing something. llvm-svn: 127934

Implementing plugins that provide commands. This checkin adds the capability for LLDB to load plugins from external dylibs that can provide new commands It exports an SBCommand class from the public API layer, and a new SBCommandPluginInterface There is a minimal load-only plugin manager built into the debugger, which can be accessed via Debugger::LoadPlugin. Plugins are loaded from two locations at debugger startup (LLDB.framework/Resources/PlugIns and ~/Library/Application Support/LLDB/PlugIns) and more can be (re)loaded via the "plugin load" command For an example of how to make a plugin, refer to the fooplugin.cpp file in examples/plugins/commands Caveats: Currently, the new API objects and features are not exposed via Python. The new commands can only be "parsed" (i.e. not raw) and get their command line via a char** parameter (we do not expose our internal Args object) There is no unloading feature, which can potentially lead to leaks if you overwrite the commands by reloading the same or different plugins There is no API exposed for option parsing, which means you may need to use getopt or roll-your-own llvm-svn: 164865

Convert the ScriptInterpreter system to a plugin-based one. Previously embedded interpreters were handled as ad-hoc source files compiled into source/Interpreter. This made it hard to disable a specific interpreter, or to add support for other interpreters and allow the developer to choose which interpreter(s) were enabled for a particular build. This patch converts script interpreters over to a plugin-based system. Script interpreters now live in source/Plugins/ScriptInterpreter, and the canonical LLDB interpreter, ScriptInterpreterPython, is moved there as well. Any new code interfacing with the Python C API must live in this location from here on out. Additionally, generic code should never need to reference or make assumptions about the presence of a specific interpreter going forward.

Convert the ScriptInterpreter system to a plugin-based one. Previously embedded interpreters were handled as ad-hoc source files compiled into source/Interpreter. This made it hard to disable a specific interpreter, or to add support for other interpreters and allow the developer to choose which interpreter(s) were enabled for a particular build. This patch converts script interpreters over to a plugin-based system. Script interpreters now live in source/Plugins/ScriptInterpreter, and the canonical LLDB interpreter, ScriptInterpreterPython, is moved there as well. Any new code interfacing with the Python C API must live in this location from here on out. Additionally, generic code should never need to reference or make assumptions about the presence of a specific interpreter going forward.

CommandInterpreter::CommandInterpreter(Debugger &debugger, ScriptLanguage script_language, bool synchronous_execution)
Change over the broadcaster/listener process to hold shared or weak pointers to each other. This should remove some infrequent teardown crashes when the listener is not the debugger's listener. Processes now need to take a ListenerSP, not a Listener&. This required changing over the Process plugin class constructors to take a ListenerSP, instead of a Listener&. Other than that there should be no functional change. <rdar://problem/24580184> CrashTracer: [USER] Xcode at …ework: lldb_private::Listener::BroadcasterWillDestruct + 39 llvm-svn: 262863

Added the concept of a Read-Eval-Print-Loop to LLDB. A REPL takes over the command line and typically treats input as source code. REPLs can also do code completion. The REPL class allows its subclasses to implement the language-specific functionality without having to know about the IOHandler-specific internals. Also added a PluginManager-based way of getting to a REPL given a language and a target. Also brought in some utility code and expression options that are useful for REPLs, such as line offsets for expressions, ANSI terminal coloring of errors, and a few IOHandler convenience functions. llvm-svn: 250753

Convert the ScriptInterpreter system to a plugin-based one. Previously embedded interpreters were handled as ad-hoc source files compiled into source/Interpreter. This made it hard to disable a specific interpreter, or to add support for other interpreters and allow the developer to choose which interpreter(s) were enabled for a particular build. This patch converts script interpreters over to a plugin-based system. Script interpreters now live in source/Plugins/ScriptInterpreter, and the canonical LLDB interpreter, ScriptInterpreterPython, is moved there as well. Any new code interfacing with the Python C API must live in this location from here on out. Additionally, generic code should never need to reference or make assumptions about the presence of a specific interpreter going forward.

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). llvm-svn: 113041

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"). llvm-svn: 114252

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.

Added more platform support. There are now some new commands: platform status -- gets status information for the selected platform platform create <platform-name> -- creates a new instance of a remote platform platform list -- list all available platforms platform select -- select a platform instance as the current platform (not working yet) When using "platform create" it will create a remote platform and make it the selected platform. For instances for iPhone OS debugging on Mac OS X one can do: (lldb) platform create remote-ios --sdk-version=4.0 Remote platform: iOS platform SDK version: 4.0 SDK path: "/Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.0" Not connected to a remote device. (lldb) file ~/Documents/a.out Current executable set to '~/Documents/a.out' (armv6). (lldb) image list [ 0] /Volumes/work/gclayton/Documents/devb/attach/a.out [ 1] /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.0/Symbols/usr/lib/dyld [ 2] /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.0/Symbols/usr/lib/libSystem.B.dylib Note that this is all happening prior to running _or_ connecting to a remote platform. Once connected to a remote platform the OS version might change which means we will need to update our dependecies. Also once we run, we will need to match up the actualy binaries with the actualy UUID's to files in the SDK, or download and cache them locally. This is just the start of the remote platforms, but this modification is the first iteration in getting the platforms really doing something. llvm-svn: 127934

Implementing plugins that provide commands. This checkin adds the capability for LLDB to load plugins from external dylibs that can provide new commands It exports an SBCommand class from the public API layer, and a new SBCommandPluginInterface There is a minimal load-only plugin manager built into the debugger, which can be accessed via Debugger::LoadPlugin. Plugins are loaded from two locations at debugger startup (LLDB.framework/Resources/PlugIns and ~/Library/Application Support/LLDB/PlugIns) and more can be (re)loaded via the "plugin load" command For an example of how to make a plugin, refer to the fooplugin.cpp file in examples/plugins/commands Caveats: Currently, the new API objects and features are not exposed via Python. The new commands can only be "parsed" (i.e. not raw) and get their command line via a char** parameter (we do not expose our internal Args object) There is no unloading feature, which can potentially lead to leaks if you overwrite the commands by reloading the same or different plugins There is no API exposed for option parsing, which means you may need to use getopt or roll-your-own llvm-svn: 164865

Cleaned up the command interpreter and the CommandObject and all subclasses to take more appropriate arguments. llvm-svn: 106615

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"). llvm-svn: 114252

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). llvm-svn: 113041

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.

Moved the execution context that was in the Debugger into the CommandInterpreter where it was always being used. Make sure that Modules can track their object file offsets correctly to allow opening of sub object files (like the "__commpage" on darwin). Modified the Platforms to be able to launch processes. The first part of this move is the platform soon will become the entity that launches your program and when it does, it uses a new ProcessLaunchInfo class which encapsulates all process launching settings. This simplifies the internal APIs needed for launching. I want to slowly phase out process launching from the process classes, so for now we can still launch just as we used to, but eventually the platform is the object that should do the launching. Modified the Host::LaunchProcess in the MacOSX Host.mm to correctly be able to launch processes with all of the new eLaunchFlag settings. Modified any code that was manually launching processes to use the Host::LaunchProcess functions. Fixed an issue where lldb_private::Args had implicitly defined copy constructors that could do the wrong thing. This has now been fixed by adding an appropriate copy constructor and assignment operator. Make sure we don't add empty ModuleSP entries to a module list. Fixed the commpage module creation on MacOSX, but we still need to train the MacOSX dynamic loader to not get rid of it when it doesn't have an entry in the all image infos. Abstracted many more calls from in ProcessGDBRemote down into the GDBRemoteCommunicationClient subclass to make the classes cleaner and more efficient. Fixed the default iOS ARM register context to be correct and also added support for targets that don't support the qThreadStopInfo packet by selecting the current thread (only if needed) and then sending a stop reply packet. Debugserver can now start up with a --unix-socket (-u for short) and can then bind to port zero and send the port it bound to to a listening process on the other end. This allows the GDB remote platform to spawn new GDB server instances (debugserver) to allow platform debugging. llvm-svn: 129351

Moved the execution context that was in the Debugger into the CommandInterpreter where it was always being used. Make sure that Modules can track their object file offsets correctly to allow opening of sub object files (like the "__commpage" on darwin). Modified the Platforms to be able to launch processes. The first part of this move is the platform soon will become the entity that launches your program and when it does, it uses a new ProcessLaunchInfo class which encapsulates all process launching settings. This simplifies the internal APIs needed for launching. I want to slowly phase out process launching from the process classes, so for now we can still launch just as we used to, but eventually the platform is the object that should do the launching. Modified the Host::LaunchProcess in the MacOSX Host.mm to correctly be able to launch processes with all of the new eLaunchFlag settings. Modified any code that was manually launching processes to use the Host::LaunchProcess functions. Fixed an issue where lldb_private::Args had implicitly defined copy constructors that could do the wrong thing. This has now been fixed by adding an appropriate copy constructor and assignment operator. Make sure we don't add empty ModuleSP entries to a module list. Fixed the commpage module creation on MacOSX, but we still need to train the MacOSX dynamic loader to not get rid of it when it doesn't have an entry in the all image infos. Abstracted many more calls from in ProcessGDBRemote down into the GDBRemoteCommunicationClient subclass to make the classes cleaner and more efficient. Fixed the default iOS ARM register context to be correct and also added support for targets that don't support the qThreadStopInfo packet by selecting the current thread (only if needed) and then sending a stop reply packet. Debugserver can now start up with a --unix-socket (-u for short) and can then bind to port zero and send the port it bound to to a listening process on the other end.

Fixed an issue where you couldn't delete a user defined regex, python, or multi-word command by adding a new "command delete" command. This new command will delete user defined regular commands, but not aliases. We still have "command unalias" to remove aliases as they are currently in different buckets. Appropriate error messages are displayed to inform the user when "command unalias" is used on removable user defined commands that points users to the "command delete" command. Added a test to verify we can remove user defined commands and also verify that "command unalias" fails when used on a user defined command. <rdar://problem/18248300> llvm-svn: 225535

Added a 'jump' command, similar to GDBs. This allows the PC to be directly changed to a different line. It's similar to the example python script in examples/python/jump.py, except implemented as a builtin. Also this version will track the current function correctly even if the target line resolves to multiple addresses. (e.g. debugging a templated function) llvm-svn: 190572

<rdar://problem/13069948> Major fixed to allow reading files that are over 4GB. The main problems were that the DataExtractor was using 32 bit offsets as a data cursor, and since we mmap all of our object files we could run into cases where if we had a very large core file that was over 4GB, we were running into the 4GB boundary. So I defined a new "lldb::offset_t" which should be used for all file offsets. After making this change, I enabled warnings for data loss and for enexpected implicit conversions temporarily and found a ton of things that I fixed.

this patch addresses several issues with "command script" subcommands: a) adds a new --synchronicity (-s) setting for "command script add" that allows the user to decide if scripted commands should run synchronously or asynchronously (which can make a difference in how events are handled) b) clears up several error messages c) adds a new --allow-reload (-r) setting for "command script import" that allows the user to reload a module even if it has already been imported before d) allows filename completion for "command script import" (much like what happens for "target create") e) prevents "command script add" from replacing built-in commands with scripted commands f) changes AddUserCommand() to take an std::string instead of a const char* (for performance reasons) plus, it fixes an issue in "type summary add" command handling which caused several test suite errors llvm-svn: 144035

Changes to Python commands: - They now have an SBCommandReturnObject instead of an SBStream as third argument - The class CommandObjectPythonFunction has been merged into CommandObjectCommands.cpp - The command to manage them is now: command script with subcommands add, list, delete, clear command alias is returned to its previous functionality - Python commands are now part of an user dictionary, instead of being seen as aliases llvm-svn: 137785

Added the ability for users to create new regex commands. To do this currently, it must be done in multi-line mode: (lldb) commands regex --help "Help text for command" --syntax "syntax for command" <cmd-name> Any example that would use "f" for "finish" when there are no arguments, and "f <num>" to do a "frame select <num>" would be: (lldb) commands regex f Enter multiple regular expressions in the form s/find/replace/ then terminate with an empty line: s/^$/finish/ s/([0-9]+)/frame select %1/ (lldb) f 11 frame select 12 ... (lldb) f finish ... Also added the string version of the OptionValue as OptionValueString. llvm-svn: 129855

<rdar://problem/13069948> Major fixed to allow reading files that are over 4GB. The main problems were that the DataExtractor was using 32 bit offsets as a data cursor, and since we mmap all of our object files we could run into cases where if we had a very large core file that was over 4GB, we were running into the 4GB boundary. So I defined a new "lldb::offset_t" which should be used for all file offsets. After making this change, I enabled warnings for data loss and for enexpected implicit conversions temporarily and found a ton of things that I fixed. Any functions that take an index internally, should use "size_t" for any indexes and also should return "size_t" for any sizes of collections. llvm-svn: 173463

Appropriate error messages are displayed to inform the user when "command unalias" is used on removable user defined commands that points users to the "command delete" command.

Three related changes to help: The default help display now shows the alias collection by default, and hides commands whose named begin with an underscore. Help is primarily useful to those unfamiliar with LLDB and should aim to answer typical questions while still being able to provide more esoteric answers when required. To that latter end an argument to include the hidden commands in help has been added, and instead of having a help flag to show aliases there is now one to hide them. This final change might be controversial as it repurposes the -a shorthand as the opposite of its original meaning. The previous implementation of OutputFormattedHelpText was easily confused by embedded newlines.

<rdar://problem/13069948> Major fixed to allow reading files that are over 4GB. The main problems were that the DataExtractor was using 32 bit offsets as a data cursor, and since we mmap all of our object files we could run into cases where if we had a very large core file that was over 4GB, we were running into the 4GB boundary. So I defined a new "lldb::offset_t" which should be used for all file offsets. After making this change, I enabled warnings for data loss and for enexpected implicit conversions temporarily and found a ton of things that I fixed. Any functions that take an index internally, should use "size_t" for any indexes and also should return "size_t" for any sizes of collections. llvm-svn: 173463

Help is primarily useful to those unfamiliar with LLDB and should aim to answer typical questions while still being able to provide more esoteric answers when required.

Fix handling of backslashes in Args parsing Summary: Presently Args::SetCommandString allows quotes to be escaped with backslash. However, the backslash itself is not removed from the argument, nor there is a way to escape the backslash itself. This leads to surprising results: "a b" c" -> 'a b', 'c' # Here we actually have an unterminated quote, but that is ignored "a b\" c" -> 'a b\" c' # We try to escape the quote. That works but the backslash is not removed. "a b\\" c" -> 'a b\\" c' # Escaping the backslash has no effect. This change changes quote handling to be more shell-like: - single quotes and backquotes are literal and there is no way to escape the closing quote or anything else inside; - inside double quotes you can use backslash to escape the closing quote and another backslash - outside any quotes, you can use backslash to escape quotes, spaces and itself. This makes the parsing more consistent with what the user is familiar and increases the probability that pasting the command line from shell to the "process launch" command "just work".

Added the ability to run expressions in any command. Expressions can be inserted in commands by using backticks: (lldb) memory read `$rsp-16` `$rsp+16` (lldb) memory read -c `(int)strlen(argv[0])` `argv[0]` The result of the expression will be inserted into the command as a sort of preprocess stage where this gets done first. We might need to tweak where this preprocess stage goes, but it is very functional already. Added ansi color support to the Debugger::FormatPrompt() so you can use things like "${ansi.fg.blue}" and "${ansi.bold}" many more. This helps in adding colors to your prompts without needing to know the ANSI color code strings. llvm-svn: 141948

<rdar://problem/11791234> Fixed a case where the python interpreter could end up holding onto a previous lldb::SBProcess (probably in lldb.process) when run under Xcode. Prior to this fix, the lldb::SBProcess held onto a shared pointer to a lldb_private::Process. This in turn could cause the process to still have a thread list with stack frames. The stack frames would have module shared pointers in the lldb_private::SymbolContext objects. We also had issues with things staying in the shared module list too long when we found things by UUID (we didn't remove the out of date ModuleSP from the global module cache). Now all of this is fixed and everything goes away between runs. llvm-svn: 160140

This is the first step of making lldb able to create target-specific things (e.g. breakpoints, stop-hooks) before we have any targets - for instance in your ~/.lldbinit file. These will then get copied over to any new targets that get created. So far, you can only make stop-hooks. Breakpoints will have to learn to move themselves from target to target for us to get them from no-target to new-target. We should also make a command & SB API way to prime this ur-target. llvm-svn: 222600

EvaluateExpressionOptions options;
This patch does a couple of things. It completes the job of using EvaluateExpressionOptions consistently throughout the inferior function calling mechanism in lldb begun in Greg's patch r194009. It removes a handful of alternate calls into the ClangUserExpression/ClangFunction/ThreadPlanCallFunction which were there for convenience. Using the EvaluateExpressionOptions removes the need for them. Using that it gets the --debug option from Greg's patch to work cleanly. It also adds another EvaluateExpressionOption to not trap exceptions when running expressions. You shouldn't use this option unless you KNOW your expression can't throw beyond itself. This is: <rdar://problem/15374885> At present this is only available through the SB API's or python. It fixes a bug where function calls would unset the ObjC & C++ exception breakpoints without checking whether they were set by somebody else already. llvm-svn: 194182

Log *log (lldb_private::GetLogIfAllCategoriesSet (LIBLLDB_LOG_COMMANDS));
Modified lldb_private::SymboleFile to be able to override where its TypeList 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. llvm-svn: 118672

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. llvm-svn: 118672

Modify HandleCommand to not do any argument processing until it has determined whether or 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

Took the knowledge of how to prepare raw & parsed commands out of CommandInterpreter and put it in CommandObject where it belongs. Also took all the cases where there were the subcommands of Multiword commands declared in the .h file for the overall command and moved them into the .cpp file. Made the CommandObject flags work for raw as well as parsed commands. Made "expr" use the flags so that it requires you to be paused to run "expr". llvm-svn: 158235

Modify HandleCommand to not do any argument processing until it has determined whether or 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

<rdar://problem/13069948> Major fixed to allow reading files that are over 4GB. The main problems were that the DataExtractor was using 32 bit offsets as a data cursor, and since we mmap all of our object files we could run into cases where if we had a very large core file that was over 4GB, we were running into the 4GB boundary. So I defined a new "lldb::offset_t" which should be used for all file offsets. After making this change, I enabled warnings for data loss and for enexpected implicit conversions temporarily and found a ton of things that I fixed. Any functions that take an index internally, should use "size_t" for any indexes and also should return "size_t" for any sizes of collections. llvm-svn: 173463

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"). llvm-svn: 114252

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.

Fix handling of backslashes in Args parsing Summary: Presently Args::SetCommandString allows quotes to be escaped with backslash. However, the backslash itself is not removed from the argument, nor there is a way to escape the backslash itself. This leads to surprising results: "a b" c" -> 'a b', 'c' # Here we actually have an unterminated quote, but that is ignored "a b\" c" -> 'a b\" c' # We try to escape the quote. That works but the backslash is not removed. "a b\\" c" -> 'a b\\" c' # Escaping the backslash has no effect. This change changes quote handling to be more shell-like: - single quotes and backquotes are literal and there is no way to escape the closing quote or anything else inside; - inside double quotes you can use backslash to escape the closing quote and another backslash - outside any quotes, you can use backslash to escape quotes, spaces and itself. This makes the parsing more consistent with what the user is familiar and increases the probability that pasting the command line from shell to the "process launch" command "just work".

<rdar://problem/13069948> Major fixed to allow reading files that are over 4GB. The main problems were that the DataExtractor was using 32 bit offsets as a data cursor, and since we mmap all of our object files we could run into cases where if we had a very large core file that was over 4GB, we were running into the 4GB boundary. So I defined a new "lldb::offset_t" which should be used for all file offsets. After making this change, I enabled warnings for data loss and for enexpected implicit conversions temporarily and found a ton of things that I fixed. Any functions that take an index internally, should use "size_t" for any indexes and also should return "size_t" for any sizes of collections. llvm-svn: 173463

Fixed a ton of gcc compile warnings Removed some unused variables, added some consts, changed some casts to const_cast. I don't think any of these changes are very controversial. Differential Revision: http://reviews.llvm.org/D9674 llvm-svn: 237218

cmd_args.SetArguments (new_args.GetArgumentCount(), new_args.GetConstArgumentVector());
- Fix alias-building & resolving to properly handle optional arguments for command options. - 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

This patch stops lldb from loading a .lldbinit file from the current working directory by default -- a typical security problem that we need to be more conservative about. It adds a new target setting, target.load-cwd-lldbinit which may be true (always read $cwd/.lldbinit), false (never read $cwd/.lldbinit) or warn (warn if there is a $cwd/.lldbinit and don't read it). The default is set to warn. If this is met with unhappiness, we can look at changing the default to true (to match current behavior) on a different platform. This does not affect reading of ~/.lldbinit - that will still be read, as before. If you run lldb in your home directory, it will not warn about the presence of a .lldbinit file there. I had to add two SB API - SBHostOS::GetUserHomeDirectory and SBFileSpec::AppendPathComponent - for the lldb driver code to be able to get the home directory path in an OS neutral manner. The warning text is There is a .lldbinit file in the current directory which is not being read. To silence this warning without sourcing in the local .lldbinit, add the following to the lldbinit file in your home directory: settings set target.load-cwd-lldbinit false To allow lldb to source .lldbinit files in the current working directory, set the value of this variable to true.

Three related changes to help: The default help display now shows the alias collection by default, and hides commands whose named begin with an underscore. Help is primarily useful to those unfamiliar with LLDB and should aim to answer typical questions while still being able to provide more esoteric answers when required. To that latter end an argument to include the hidden commands in help has been added, and instead of having a help flag to show aliases there is now one to hide them. This final change might be controversial as it repurposes the -a shorthand as the opposite of its original meaning. The previous implementation of OutputFormattedHelpText was easily confused by embedded newlines. The new algorithm correctly breaks on the FIRST newline or LAST space/tab before the target column count rather than treating all whitespace interchangeably. Command interpreters now have the ability to specify help prologue text and a command prefix string. Neither are used in the current LLDB sources but are required to support REPL-like extensions where LLDB commands must be prefixed and additional help text is required to explain how to access traditional debugging commands. <rdar://problem/17751929> <rdar://problem/16953815> <rdar://problem/16953841> <rdar://problem/16930173> <rdar://problem/16879028> llvm-svn: 226068

Moved the execution context that was in the Debugger into the CommandInterpreter where it was always being used. Make sure that Modules can track their object file offsets correctly to allow opening of sub object files (like the "__commpage" on darwin). Modified the Platforms to be able to launch processes. The first part of this move is the platform soon will become the entity that launches your program and when it does, it uses a new ProcessLaunchInfo class which encapsulates all process launching settings. This simplifies the internal APIs needed for launching. I want to slowly phase out process launching from the process classes, so for now we can still launch just as we used to, but eventually the platform is the object that should do the launching. Modified the Host::LaunchProcess in the MacOSX Host.mm to correctly be able to launch processes with all of the new eLaunchFlag settings. Modified any code that was manually launching processes to use the Host::LaunchProcess functions. Fixed an issue where lldb_private::Args had implicitly defined copy constructors that could do the wrong thing. This has now been fixed by adding an appropriate copy constructor and assignment operator. Make sure we don't add empty ModuleSP entries to a module list. Fixed the commpage module creation on MacOSX, but we still need to train the MacOSX dynamic loader to not get rid of it when it doesn't have an entry in the all image infos. Abstracted many more calls from in ProcessGDBRemote down into the GDBRemoteCommunicationClient subclass to make the classes cleaner and more efficient. Fixed the default iOS ARM register context to be correct and also added support for targets that don't support the qThreadStopInfo packet by selecting the current thread (only if needed) and then sending a stop reply packet. Debugserver can now start up with a --unix-socket (-u for short) and can then bind to port zero and send the port it bound to to a listening process on the other end. This allows the GDB remote platform to spawn new GDB server instances (debugserver) to allow platform debugging. llvm-svn: 129351

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. llvm-svn: 140298

<rdar://problem/11791234> Fixed a case where the python interpreter could end up holding onto a previous lldb::SBProcess (probably in lldb.process) when run under Xcode. Prior to this fix, the lldb::SBProcess held onto a shared pointer to a lldb_private::Process. This in turn could cause the process to still have a thread list with stack frames. The stack frames would have module shared pointers in the lldb_private::SymbolContext objects. We also had issues with things staying in the shared module list too long when we found things by UUID (we didn't remove the out of date ModuleSP from the global module cache). Now all of this is fixed and everything goes away between runs. llvm-svn: 160140

Moved the execution context that was in the Debugger into the CommandInterpreter where it was always being used. Make sure that Modules can track their object file offsets correctly to allow opening of sub object files (like the "__commpage" on darwin). Modified the Platforms to be able to launch processes. The first part of this move is the platform soon will become the entity that launches your program and when it does, it uses a new ProcessLaunchInfo class which encapsulates all process launching settings. This simplifies the internal APIs needed for launching. I want to slowly phase out process launching from the process classes, so for now we can still launch just as we used to, but eventually the platform is the object that should do the launching. Modified the Host::LaunchProcess in the MacOSX Host.mm to correctly be able to launch processes with all of the new eLaunchFlag settings. Modified any code that was manually launching processes to use the Host::LaunchProcess functions. Fixed an issue where lldb_private::Args had implicitly defined copy constructors that could do the wrong thing. This has now been fixed by adding an appropriate copy constructor and assignment operator. Make sure we don't add empty ModuleSP entries to a module list. Fixed the commpage module creation on MacOSX, but we still need to train the MacOSX dynamic loader to not get rid of it when it doesn't have an entry in the all image infos. Abstracted many more calls from in ProcessGDBRemote down into the GDBRemoteCommunicationClient subclass to make the classes cleaner and more efficient. Fixed the default iOS ARM register context to be correct and also added support for targets that don't support the qThreadStopInfo packet by selecting the current thread (only if needed) and then sending a stop reply packet. Debugserver can now start up with a --unix-socket (-u for short) and can then bind to port zero and send the port it bound to to a listening process on the other end. This allows the GDB remote platform to spawn new GDB server instances (debugserver) to allow platform debugging. llvm-svn: 129351

Don't limit StreamTee to just two streams. It now can contain 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

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). llvm-svn: 130721

This adds a "batch mode" to lldb kinda like the gdb batch mode. It will quit the debugger after all the commands have been executed except if one of the commands was an execution control command that stopped because of a signal or exception. Also adds a variant of SBCommandInterpreter::HandleCommand that takes an SBExecutionContext. That way you can run an lldb command targeted at a particular target, thread or process w/o having to select same before running the command. Also exposes CommandInterpreter::HandleCommandsFromFile to the SBCommandInterpreter API, since that seemed generally useful. llvm-svn: 219654

Complete rewrite of interactive editing support for single- and multi-line input. Improvements include: * Use of libedit's wide character support, which is imperfect but a distinct improvement over ASCII-only * Fallback for ASCII editing path * Support for a "faint" prompt clearly distinguished from input * Breaking lines and insert new lines in the middle of a batch by simply pressing return * Joining lines with forward and backward character deletion * Detection of paste to suppress automatic formatting and statement completion tests * Correctly reformatting when lines grow or shrink to occupy different numbers of rows * Saving multi-line history, and correctly preserving the "tip" of history during editing * Displaying visible ^C and ^D indications when interrupting input or sending EOF * Fledgling VI support for multi-line editing * General correctness and reliability improvements llvm-svn: 222163

This adds a "batch mode" to lldb kinda like the gdb batch mode. It will quit the debugger after all the commands have been executed except if one of the commands was an execution control command that stopped because of a signal or exception. Also adds a variant of SBCommandInterpreter::HandleCommand that takes an SBExecutionContext. That way you can run an lldb command targeted at a particular target, thread or process w/o having to select same before running the command. Also exposes CommandInterpreter::HandleCommandsFromFile to the SBCommandInterpreter API, since that seemed generally useful. llvm-svn: 219654

ScriptInterpreter *
Convert the ScriptInterpreter system to a plugin-based one. Previously embedded interpreters were handled as ad-hoc source files compiled into source/Interpreter. This made it hard to disable a specific interpreter, or to add support for other interpreters and allow the developer to choose which interpreter(s) were enabled for a particular build. This patch converts script interpreters over to a plugin-based system. Script interpreters now live in source/Plugins/ScriptInterpreter, and the canonical LLDB interpreter, ScriptInterpreterPython, is moved there as well. Any new code interfacing with the Python C API must live in this location from here on out. Additionally, generic code should never need to reference or make assumptions about the presence of a specific interpreter going forward.

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"). llvm-svn: 114252

Moved the execution context that was in the Debugger into the CommandInterpreter where it was always being used. Make sure that Modules can track their object file offsets correctly to allow opening of sub object files (like the "__commpage" on darwin). Modified the Platforms to be able to launch processes. The first part of this move is the platform soon will become the entity that launches your program and when it does, it uses a new ProcessLaunchInfo class which encapsulates all process launching settings. This simplifies the internal APIs needed for launching. I want to slowly phase out process launching from the process classes, so for now we can still launch just as we used to, but eventually the platform is the object that should do the launching. Modified the Host::LaunchProcess in the MacOSX Host.mm to correctly be able to launch processes with all of the new eLaunchFlag settings. Modified any code that was manually launching processes to use the Host::LaunchProcess functions. Fixed an issue where lldb_private::Args had implicitly defined copy constructors that could do the wrong thing. This has now been fixed by adding an appropriate copy constructor and assignment operator. Make sure we don't add empty ModuleSP entries to a module list. Fixed the commpage module creation on MacOSX, but we still need to train the MacOSX dynamic loader to not get rid of it when it doesn't have an entry in the all image infos. Abstracted many more calls from in ProcessGDBRemote down into the GDBRemoteCommunicationClient subclass to make the classes cleaner and more efficient. Fixed the default iOS ARM register context to be correct and also added support for targets that don't support the qThreadStopInfo packet by selecting the current thread (only if needed) and then sending a stop reply packet. Debugserver can now start up with a --unix-socket (-u for short) and can then bind to port zero and send the port it bound to to a listening process on the other end. This allows the GDB remote platform to spawn new GDB server instances (debugserver) to allow platform debugging. llvm-svn: 129351

Prior to this fix, the lldb::SBProcess held onto a shared pointer to a lldb_private::Process. This in turn could cause the process to still have a thread list with stack frames. The stack frames would have module shared pointers in the lldb_private::SymbolContext objects. We also had issues with things staying in the shared module list too long when we found things by UUID (we didn't remove the out of date ModuleSP from the global module cache).

This adds a "batch mode" to lldb kinda like the gdb batch mode. It will quit the debugger after all the commands have been executed except if one of the commands was an execution control command that stopped because of a signal or exception. Also adds a variant of SBCommandInterpreter::HandleCommand that takes an SBExecutionContext. That way you can run an lldb command targeted at a particular target, thread or process w/o having to select same before running the command. Also exposes CommandInterpreter::HandleCommandsFromFile to the SBCommandInterpreter API, since that seemed generally useful. llvm-svn: 219654

Batch mode is supposed to stop execution and return control to the user when an exceptional stop occurs (crash, signal or instrumentation). But attach always stops with a SIGSTOP on OSX (maybe on Linux too?) which would short circuit the rest of the commands given. This change allows a command result object to indicate that it expected to leave the process stopped with an exceptional stop reason, and it is okay for batch mode to keep going. <rdar://problem/22243143> llvm-svn: 257120

if ((reason == eStopReasonSignal
|| reason == eStopReasonException
|| reason == eStopReasonInstrumentation)
&& !result.GetAbnormalStopWasExpected())
This adds a "batch mode" to lldb kinda like the gdb batch mode. It will quit the debugger after all the commands have been executed except if one of the commands was an execution control command that stopped because of a signal or exception. Also adds a variant of SBCommandInterpreter::HandleCommand that takes an SBExecutionContext. That way you can run an lldb command targeted at a particular target, thread or process w/o having to select same before running the command. Also exposes CommandInterpreter::HandleCommandsFromFile to the SBCommandInterpreter API, since that seemed generally useful. llvm-svn: 219654

Rework the way we pass "run multiple command" options to the various API's that do that (RunCommandInterpreter, HandleCommands, HandleCommandsFromFile) to gather the options into an options class. Also expose that to the SB API's. Change the way the "-o" options to the lldb driver are processed so: 1) They are run synchronously - didn't really make any sense to run the asynchronously. 2) The stop on error 3) "quit" in one of the -o commands will not quit lldb - not the command interpreter that was running the -o commands.
