2011-10-23Move Python.h includes out of the headers into the .cpp file where it's ↵Benjamin Kramer
actually used. Python.h includes a ton of macros that can cause weird behavior down the road. llvm-svn: 142754
2011-10-19Moved lldb::user_id_t values to be 64 bit. This was going to be needed forGreg Clayton
process IDs, and thread IDs, but was mainly needed for for the UserID's for Types so that DWARF with debug map can work flawlessly. With DWARF in .o files the type ID was the DIE offset in the DWARF for the .o file which is not unique across all .o files, so now the SymbolFileDWARFDebugMap class will make the .o file index part (the high 32 bits) of the unique type identifier so it can uniquely identify the types. llvm-svn: 142534
2011-10-17this patch introduces a new command script import command which takes as ↵Enrico Granata
input a filename for a Python script and imports the module contained in that file. the containing directory is added to the Python path such that dependencies are honored. also, the module may contain an __lldb_init_module(debugger,dict) function, which gets called after importing, and which can somehow initialize the module's interaction with lldb llvm-svn: 142283
2011-09-22Converted the lldb_private::Process over to use the intrusiveGreg Clayton
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

stdarg formats to use __attribute__ format so the compiler can flag incorrect uses. Fix all incorrect uses. Most of these are innocuous, a few were resulting in crashes. llvm-svn: 140185

2011-09-09Fixing an issue with Python commands defined interactivelyEnrico Granata
llvm-svn: 139345
2011-09-06Redesign of the interaction between Python and frozen objects:Enrico Granata
- introduced two new classes ValueObjectConstResultChild and ValueObjectConstResultImpl: the first one is a ValueObjectChild obtained from a ValueObjectConstResult, the second is a common implementation backend for VOCR and VOCRCh of method calls meant to read through pointers stored in frozen objects ; now such reads transparently move from host to target as required - as a consequence of the above, removed code that made target-memory copies of expression results in several places throughout LLDB, and also removed code that enabled to recognize an expression result VO as such - introduced a new GetPointeeData() method in ValueObject that lets you read a given amount of objects of type T from a VO representing a T* or T[], and doing dereferences transparently in private layer it returns a DataExtractor ; in public layer it returns an instance of a newly created lldb::SBData - as GetPointeeData() does the right thing for both frozen and non-frozen ValueObject's, reimplemented ReadPointedString() to use it en lieu of doing the raw read itself - introduced a new GetData() method in ValueObject that lets you get a copy of the data that backs the ValueObject (for pointers, this returns the address without any previous dereferencing steps ; for arrays it actually reads the whole chunk of memory) in public layer this returns an SBData, just like GetPointeeData() - introduced a new CreateValueFromData() method in SBValue that lets you create a new SBValue from a chunk of data wrapped in an SBData the limitation to remember for this kind of SBValue is that they have no address: extracting the address-of for these objects (with any of GetAddress(), GetLoadAddress() and AddressOf()) will return invalid values - added several tests to check that "p"-ing objects (STL classes, char* and char[]) will do the right thing Solved a bug where global pointers to global variables were not dereferenced correctly for display New target setting "max-string-summary-length" gives the maximum number of characters to show in a string when summarizing it, instead of the hardcoded 128 Solved a bug where the summary for char[] and char* would not be shown if the ValueObject's were dumped via the "p" command Removed m_pointers_point_to_load_addrs from ValueObject. Introduced a new m_address_type_of_children, which each ValueObject can set to tell the address type of any pointers and/or references it creates. In the current codebase, this is load address most of the time (the only notable exception being file addresses that generate file address children UNLESS we have a live process) Updated help text for summary-string Fixed an issue in STL formatters where std::stlcontainer::iterator would match the container's synthetic children providers Edited the syntax and help for some commands to have proper argument types llvm-svn: 139160

2011-08-22- Support for Python namespaces:Enrico Granata
If you have a Python module foo, in order to use its contained objects in LLDB you do not need to use 'from foo import *'. You can use 'import foo', and then refer to items in foo as 'foo.bar', and LLDB will know how to resolve bar as a member of foo. Accordingly, GNU libstdc++ formatters have been moved from the global namespace to gnu_libstdcpp and a few test cases are also updated to reflect the new convention. Python docs suggest using a plain 'import' en lieu of 'from-import'. llvm-svn: 138244

2011-08-17First round of code cleanups:Enrico Granata
- all instances of "vobj" have been renamed to "valobj" - class Debugger::Formatting has been renamed to DataVisualization (defined in FormatManager.h/cpp) The interface to this class has not changed - FormatCategory now uses ConstString's as keys to the navigators instead of repeatedly casting from ConstString to const char* and back all the time Next step is making the same happen for categories themselves - category gnu-libstdc++ is defined in the constructor for a FormatManager The source code for it is defined in gnu_libstdcpp.py, drawn from examples/synthetic at compile time All references to previous 'osxcpp' name have been removed from both code and file names Functional changes: - the name of the option to use a summary string for 'type summary add' has changed from the previous --format-string to the new --summary-string. It is expected that the short option will change from -f to -s, and -s for --python-script will become -o llvm-svn: 137886
2011-08-17New category "gnu-libstdc++" provides summary for std::string and synthetic ↵Enrico Granata
children for types std::map, std::list and std::vector The category is enabled by default. If you run into issues with it, disable it and the previous behavior of LLDB is restored ** This is a temporary solution. The general solution to having formatters pulled in at startup should involve going through the Platform. Fixed an issue in type synthetic list where a category with synthetic providers in it was not shown if all the providers were regex-based llvm-svn: 137850
2011-08-17When defining a scripted command, it is possible to provide a docstring and ↵Enrico Granata
that will be used as the help text for the command If no docstring is provided, a default help text is created LLDB will refuse to create scripted commands if the scripting language is anything but Python Some additional comments in AppleObjCRuntimeV2.cpp to describe the memory layout expected by the dynamic type lookup code llvm-svn: 137801
2011-08-16Changes to Python commands:Enrico Granata
- 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
2011-08-16Python commands:Enrico Granata
It is now possible to use 'command alias --python' to define a command name that actually triggers execution of a Python function (e.g. command alias --python foo foo_impl makes a command named 'foo' that runs Python function 'foo_impl') The Python function foo_impl should have as signature: def foo_impl(debugger, args, stream, dict): where debugger is an object wrapping an LLDB SBDebugger args is the command line arguments, as an unparsed Python string stream is an SBStream that represents the standard output dict is an internal utility parameter and should be left untouched The function should return None on no error, or an error string to describe any problems llvm-svn: 137722

2011-07-29Public API changes:Enrico Granata
- Completely new implementation of SBType - Various enhancements in several other classes Python synthetic children providers for std::vector<T>, std::list<T> and std::map<K,V>: - these return the actual elements into the container as the children of the container - basic template name parsing that works (hopefully) on both Clang and GCC - find them in examples/synthetic and in the test suite in functionalities/data-formatter/data-formatter-python-synth New summary string token ${svar : - the syntax is just the same as in ${var but this new token lets you read the values coming from the synthetic children provider instead of the actual children - Python providers above provide a synthetic child len that returns the number of elements into the container Full bug fix for the issue in which getting byte size for a non-complete type would crash LLDB Several other fixes, including: - inverted the order of arguments in the ClangASTType constructor - EvaluationPoint now only returns SharedPointer's to Target and Process - the help text for several type subcommands now correctly indicates argument-less options as such llvm-svn: 136504
2011-07-25new flag -P to type synth add lets you type a Python class interactivelyEnrico Granata
added a final newline to fooSynthProvider.py new option to automatically save user input in InputReaderEZ checking for NULL pointers in several new places llvm-svn: 135916
2011-07-24Python synthetic children:Enrico Granata
- you can now define a Python class as a synthetic children producer for a type the class must adhere to this "interface": def __init__(self, valobj, dict): def get_child_at_index(self, index): def get_child_index(self, name): then using type synth add -l className typeName (e.g. type synth add -l fooSynthProvider foo) (This is still WIP with lots to be added) A small test case is available also as reference llvm-svn: 135865
2011-07-15Python summary strings:Enrico Granata
- you can use a Python script to write a summary string for data-types, in one of three ways: -P option and typing the script a line at a time -s option and passing a one-line Python script -F option and passing the name of a Python function these options all work for the "type summary add" command your Python code (if provided through -P or -s) is wrapped in a function that accepts two parameters: valobj (a ValueObject) and dict (an LLDB internal dictionary object). if you use -F and give a function name, you're expected to define the function on your own and with the right prototype. your function, however defined, must return a Python string - test case for the Python summary feature - a few quirks: Python summaries cannot have names, and cannot use regex as type names both issues will be fixed ASAP major redesign of type summary code: - type summary working with strings and type summary working with Python code are two classes, with a common base class SummaryFormat - SummaryFormat classes now are able to actively format objects rather than just aggregating data - cleaner code to print descriptions for summaries the public API now exports a method to easily navigate a ValueObject hierarchy New InputReaderEZ and PriorityPointerPair classes Several minor fixes and improvements llvm-svn: 135238
2011-06-16Add 'batch_mode' to CommandInterpreter. Modify InputReaders toCaroline Tice
not write output (prompts, instructions,etc.) if the CommandInterpreter is in batch_mode. Also, finish updating InputReaders to write to the asynchronous stream, rather than using the Debugger's output file directly. llvm-svn: 133162
2011-06-14Add error message; clean up comment.Caroline Tice
llvm-svn: 132997
2011-06-13Cleaning up the Python script interpreter: Use theCaroline Tice
embedded_interpreter.py file rather than keeping it all in a string and compiling the string (easier to maintain, easier to read, remove redundancy). llvm-svn: 132935
2011-06-02Use Py_InitializeEx(0) instead of Py_Initialize,Caroline Tice
to prevent Python from installing its own signal handlers. llvm-svn: 132492
2011-05-03Pre-load the Python script interpreter with the followingCaroline Tice
convenience variables (from the ExecutionContext) each time it is entered: lldb.debugger, lldb.target, lldb.process, lldb.thread, lldb.frame. If a frame (or thread, process, etc) does not currently exist, the variable contains the Python value 'None'. llvm-svn: 130792
2011-05-02This patch captures and serializes all output being written by theCaroline Tice
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
2011-03-22Abtracted the innards of lldb-core away from the SB interface. There was someGreg Clayton
overlap in the SWIG integration which has now been fixed by introducing callbacks for initializing SWIG for each language (python only right now). There was also a breakpoint command callback that called into SWIG which has been abtracted into a callback to avoid cross over as well. Added a new binary: lldb-platform This will be the start of the remote platform that will use as much of the Host functionality to do its job so it should just work on all platforms. It is pretty hollowed out for now, but soon it will implement a platform using the GDB remote packets as the transport. llvm-svn: 128053

2011-02-08Patch that allows for thread_t to be something more complex than anGreg Clayton
integer. Modified patch from Kirk Beitz. llvm-svn: 125067
2011-02-07Abtract terminal stuff into a new lldb_private::Terminal classGreg Clayton
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
2011-02-07More termios fixes. We need to currently make sure to include:Greg Clayton
#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

2011-01-27Added support for some new environment variables within LLDB to enable someGreg Clayton
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") for all launched processes 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. llvm-svn: 124341
2011-01-25Enabled extra warnings and fixed a bunch of small issues.Greg Clayton
llvm-svn: 124250
2011-01-17Replace Mutex guarding python interpreter access with Predicate,Caroline Tice
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
2011-01-14Recent modifications to the Python script interpreter caused some problemsCaroline Tice
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
2011-01-14Split up the Python script interpreter code to allow multiple script ↵Caroline Tice
interpreter objects to 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
2010-12-15Add termination instructions when entering the interactive script interpreter.Caroline Tice
llvm-svn: 121884
2010-11-19Add the ability to catch and do the right thing with Interrupts (often ↵Caroline Tice
control-c) and end-of-file (often control-d). llvm-svn: 119837
2010-11-10Move the embedded Python interpreter onto a separate thread, to preventCaroline Tice
main thread from having to wait on it (which was causing some I/O hangs). llvm-svn: 118700
2010-10-28Remove references to particular Python version (use the system defaultCaroline Tice
version); change include statements to use Python.h in the Python framework on Mac OS X systems; leave it using regular Python.h on other systems. Note: I think this *ought* to work properly on Linux systems, but I don't have a system to test it on... llvm-svn: 117612
