Enrico Granata 274fd6e965 Fixed some SWIG interoperability issues
llvm-svn: 138154
2011-08-19 23:56:34 +00:00
Greg Clayton 756f8ae520 Fixed an issue where even if the communication object had Clear() called on
it, it could try and call through to an installed callback.

Greg Clayton 7d47a66379 Added the ability to create a SBCommandReturnObject object from a pointer
and also to later release the ownership of the pointer object. This was needed
for SWIG interaction.

Enrico Granata 58ad33440a Taking care of an issue with using lldb_private types in SBCommandInterpreter.cpp ; Making NSString test case work on Snow Leopard ; Removing an unused variable warning
llvm-svn: 138105
2011-08-19 21:56:10 +00:00
Enrico Granata d64d0bc0ea - Now using ${var} as the summary for an aggregate type will produce "name-of-type @ object-location" instead of giving an error
e.g. you may get "foo_class @ 0x123456" when typing "type summary add -f ${var} foo_class"
- Added a new special formatting token %T for summaries. This shows the type of the object.
  Using it, the new "type @ location" summary could be manually generated by writing ${var%T} @ ${var%L}
- Bits and pieces required to support "frame variable array[n-m]"
  The feature is not enabled yet because some additional design and support code is required, but the basics
  are getting there
- Fixed a potential issue where a ValueObjectSyntheticFilter was not holding on to its SyntheticChildrenSP
  Because of the way VOSF are being built now, this has never been an actual issue, but it is still sensible for
  a VOSF to hold on to the SyntheticChildrenSP as well as to its FrontEnd

Johnny Chen 758f288cdd Add a Python script to locate each binary file under a root directory which matches some pathname pattern
and to invoke lldb-disasm.py on the binary file to disassemble its symbols.  The number of symbols can
be specified by, for example, '-n 10000', to specify 10,000 symbols to disassemble for each module.
By default, only 1000 symbols from each module are disassembled.

Example:

utils/test/run-dis.py -r '/Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.3/Symbols' -p '^/System/Library/.*Frameworks/.*\.framework/[^/]+$'

tries to disassemble every public/private frameworks (by default only 1000 symbols are disassembled) under iOS4.3.

2011-08-19 17:18:31 +00:00
Sean Callanan a87bee84cf Refined the rollback to LLVM, picking up a newer
revision and adding a patch that fixes an AsmParser
crash on ARM.

One feature that we unfortunately lost (for the
moment!) is the ability to cast unknown code symbols
to arbitrary function types and put the resulting
function pointer in a result variable.  This feature
will be back, though.

Enrico Granata 02b6676d2b Third round of code cleanups:
- reorganizing the PTS (Partial Template Specializations) in FormatManager.h
 - applied a patch by Filipe Cabecinhas to make LLDB compile with GCC
Functional changes:
 - fixed an issue where command type summary add for type "struct Foo" would not match any types.
   currently, "struct" will be stripped off and type "Foo" will be matched.
   similar behavior occurs for class, enum and union specifiers.

Johnny Chen 31963cea0a Add a decorator for marking clang only expectedFailure. Use it for the test_step_over_3_times_with_dsym/dwarf()
test cases in TestThreadAPI.py by decorating it with @expectedFailureClang.

Example:

    @expectedFailureClang
    @python_api_test
    def test_step_over_3_times_with_dwarf(self):
        """Test Python SBThread.StepOver() API."""
        # We build a different executable than the default buildDwarf() does.
        d = {'CXX_SOURCES': 'main2.cpp', 'EXE': self.exe_name}
        self.buildDwarf(dictionary=d)
        self.setTearDownCleanup(dictionary=d)
        self.step_over_3_times(self.exe_name)

Johnny Chen 293683b6c4 Add an option (-p regexp-pattern) to specify the regular expression symbol pattern we're interested in disassembling.
An example:

utils/test/lldb-disasm.py -C "platform select remote-ios" -o "-b -n" -e '~/CoreFoundation' -n 20 -p '-\[NSArray .+\]'

disassembles the first 20 NSArray instance methods found in the CoreFoundation module.

Johnny Chen 901209dcca Add an option '-q' to have quiet disassembly by not printing out the disassembled result.
This could be useful by reducing the strain on standard output.

Sean Callanan 6afe390810 Because of disassembler crashes, I rolled back
LLVM to pull in the older ARM disassembler.  I
also modified our build scripts to support
building LLVM from one SVN revision and Clang
from another.

These are temporary measures; as soon as we
get some solid testing in with the new ARM
disassembler, we plan to switch right back.

llvm-svn: 137965
2011-08-18 18:18:33 +00:00
Enrico Granata 85933ed40c Second round of code cleanups:
- reorganizing classes layout to have public part first
   Typedefs that we want to keep private, but must be defined for some public code to work correctly are an exception
 - avoiding methods in the form T foo() { code; } all on one-line
 - moving method implementations from .h to .cpp whenever feasible
   Templatized code is an exception and so are very small methods
 - generally, adhering to coding conventions followed project-wide
Functional changes:
 - fixed an issue where using ${var} in a summary for an aggregate, and then displaying a pointer-to-aggregate would lead to no summary being displayed
   The issue was not a major one because all ${var} was meant to do in that context was display an error for invalid use of pointer
   Accordingly fixed test cases and added a new test case

2011-08-18 02:29:05 +00:00
Enrico Granata c482a19294 First round of code cleanups:
- 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
2011-08-17 22:13:59 +00:00
Enrico Granata 217f91fc57 New category "gnu-libstdc++" provides summary for std::string and synthetic 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

Enrico Granata 99f0b8f935 When defining a scripted command, it is possible to provide a docstring and that will be used as the help text for the command
If no docstring is provided, a default help text is created

Enrico Granata 223383ed6c 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

Greg Clayton 72da397a69 Fixed an issue where we could end up creating multiple
C++ methods for a function depending on how the DWARF was 
created. Now we parse the class type from the definition,
and all methods that use DW_AT_specification or DW_AT_abstract_origin
attributes to point to the definition, now won't create
duplicate entries. This is in response to how clang++ creates
much different DWARF than gcc.

Enrico Granata be93a35a8a Python commands:
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

Greg Clayton 7e9b1fd045 We were leaking a stack frame in StackFrameList in Thread.cpp which could
cause extra shared pointer references to one or more modules to be leaked.
This would cause many object files to stay around the life of LLDB, so after
a recompile and rexecution, we would keep adding more and more memory. After
fixing the leak, we found many cases where leaked stack frames were still
being used and causing crashes in the test suite. These are now all resolved.

Greg Clayton 5113dc8e54 Fixed some issues with parsing C++ methods where our detection
was failing if the DWARF was laid out in a certain way. The way
we detect C++ classes is now more robust so that a class method
can be defined outside of the class and refer to a definition inside
the class with a DW_AT_specification or DW_AT_abstract_origin attribute.

Fixed a case in Thread.cpp where we were looking up info in the frame
when we didn't need to. This was from some changes to support external
editors. Now the info is only looked up if needed.

If the IOChannel has already freed out its m_driver member, and

character), just skip that char instead of trying to write through

Enrico Granata 22c55d180d *Some more optimizations in usage of ConstString
*New setting target.max-children-count gives an upper-bound to the number of child objects that will be displayed at each depth-level
  This might be a breaking change in some scenarios. To override the new limit you can use the --show-all-children (-A) option
  to frame variable or increase the limit in your lldbinit file
*Command "type synthetic" has been split in two:
  - "type synthetic" now only handles Python synthetic children providers
  - the new command "type filter" handles filters
  Because filters and synthetic providers are both ways to replace the children of a ValueObject, only one can be effective at any given time.

Sean Callanan 793d6330cd Updated LLVM/Clang to to pick up fixes for a
problem in which the following cast:
–
expr (int (*)(const char*, ...))printf
-
caused a crash.  This had several causes:

  - First, Clang did not support implicit
    casts of a function of unknown type to
    a function pointer.

  - Second, after this was fixed, the
    Clang AST importer did not support
    importing function pointer types
    produced by resolving these casts.

These two problems are now resolved, and
I have added a test case to verify that
they work.  I also did a little bit of
build-system cleanup because we now use
libEnhancedDisassembly.a instead of the
.dylib.

Enrico Granata 8c9d35603e Fixed an issue where a pointer's address was being logged instead of its value
Access to synthetic children by name:
 if your object has a synthetic child named foo you can now type
  frame variable object.foo (or ->foo if you have a pointer)
  and that will print the value of the synthetic child
  (if your object has an actual child named foo, the actual child prevails!)
 this behavior should also work in summaries, and you should be able to use
 ${var.foo} and ${svar.foo} interchangeably
  (but using svar.foo will mask an actual child named foo)

Greg Clayton aa51684318 Patch for "process load" by Filipe Cabecinhas.
Filipe was attempting to do a:

(lldb) process load ~/path/foo.dylib

But the process load command wasn't resolving the path. We have to be careful
about resolving the path here because we want to do it in terms of the platform
we are using. the "~/" can mean a completely different path if you are remotely
debugging on another machine as another user. So to support this, platforms now
can resolve remote paths:

bool
Platform::ResolveRemotePath (const FileSpec &platform_path,
                             FileSpec &resolved_platform_path);

The host/local platform will just resolve the path.

This is helping us track down some extra references to ModuleSP objects that

Added a module pointer accessor to target and change a lot of code to use 
it where it would be more efficient.

"taret delete" can now specify "--clean=1" which will cleanup the global module
list for any orphaned module in the shared module cache which can save memory
and also help track down module reference leaks like we have now.

Greg Clayton 3418c85771 While tracking down memory consumption issue a few things were needed: the
ability to dump more information about modules in "target modules list". We
can now dump the shared pointer reference count for modules, the pointer to
the module itself (in case performance tools can help track down who has
references to said pointer), and the modification time.

Added "target delete [target-idx ...]" to be able to delete targets when they
are no longer needed. This will help track down memory usage issues and help 
to resolve when module ref counts keep getting incremented. If the command gets
no arguments, the currently selected target will be deleted. If any arguments 
are given, they must all be valid target indexes (use the "target list" 
command to get the current target indexes).

Took care of a bunch of "no newline at end of file" warnings.

TimeValue objects can now dump their time to a lldb_private::Stream object.

Modified the "target modules list --global" command to not error out if there
are no targets since it doesn't require a target.

Fixed an issue in the MacOSX DYLD dynamic loader plug-in where if a shared 
library was updated on disk, we would keep using the older one, even if it was
updated.

Don't allow the ModuleList::GetSharedModule(...) to return an empty module.
Previously we could specify a valid path on disc to a module, and specify an
architecture that wasn't contained in that module and get a shared pointer to
a module that wouldn't be able to return an object file or a symbol file. We
now make sure an object file can be extracted prior to adding the shared pointer
to the module to get added to the shared list.

Enrico Granata 27b625e12f Basic support for reading synthetic children by index:
if your datatype provides synthetic children, "frame variable object[index]" should now do the right thing

  object is not a pointer nor an array (frame variable ignores potential overload of [])
  object is a pointer to an Objective-C class (which cannot be dereferenced)
 expression will still run operator[] if available and complain if it cannot do so

Sean Callanan 72e4940bd1 This is an overhaul of the expression parser code
that detects what context the current expression is
meant to execute in.  LLDB now properly consults
the method declaration in the debug information
rather than trying to hunt down the "this" or "self"
pointer by name, which can be misleading.

Other fixes include:

- LLDB now properly detects that it is inside
  an inlined C++ member function.

- LLDB now allows access to non-const members when
  in const code.

- The functions in SymbolFile that locate the
  DeclContext containing a DIE have been renamed
  to reflect what they actually do.  I have added
  new functions that find the DeclContext for the
  DIE itself.

I have also introduced testcases for C++ and 
Objective-C.

is defined for SBTypeList, and returns 0.

Sean Callanan 0c4d8d25a7 Fixed a problem that caused LLDB to fail to execute
expressions that used function pointers.  The problem
was that IRForTarget previously only scanned the IR
for the expression for call instructions; if a function
was used in another context, it was ignored.

Now LLDB scans the Module for functions that are only
declared (not also defined -- so these are externals);
it then constructs function pointers for these
functions and substitutes them wherever the function
is used.

Also made some changes so that "expr main" works just
as well as "expr &main"; they end up being the same
code, but LLDB was generating the result variable in
different ways.

Sean Callanan cc427fadec This change brings in the latest LLVM/Clang, and
completes the support in the LLDB expression parser
for incomplete types.  Clang now imports types
lazily, and we complete those types as necessary.

Changes include:

- ClangASTSource now supports three APIs which it
  passes to ClangExpressionDeclMap.  CompleteType
  completes a TagDecl or an ObjCInterfaceDecl when
  needed; FindExternalVisibleDecls finds named
  entities that are visible in the expression's
  scope; and FindExternalLexicalDecls performs a
  (potentially restricted) search for entities
  inside a lexical scope like a namespace.  These
  changes mean that entities in namespaces should
  work normally.

- The SymbolFileDWARF code for searching a context
  for a specific name is now more general, and can
  search arbitrary contexts.

- We are continuing to adapt our calls into LLVM
  from interfaces that take start and end iterators
  when accepting multiple items to interfaces that
  use ArrayRef.

- I have cleaned up some code, especially our use
  of namespaces.

This change is neutral for our testsuite and greatly
improves correctness for large programs (like Clang)
with complicated type systems.  It should also lay
the groundwork for improving the expression parser's
performance as we are lazier and lazier about
providing type information.

Johnny Chen 4a57d122fe Add a redo.py script which takes a session directory name as arg and digs into the directory
to find out the tests which failed/errored and need re-running.  The dotest.py test driver
script is modified to allow specifying multiple -f testclass.testmethod in the command line
to accommodate the redo functionality.

An example,

 $ ./redo.py -n 2011-07-29-11_50_14

Enrico Granata ebbe5643b2 new synthetic children provider for CFString and related classes ; test case for it
llvm-svn: 136525
2011-07-29 21:31:46 +00:00
Enrico Granata 6f3533fb1d Public API changes:
- 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

self.expect("expression -- '(anonymous namespace)::i'", VARIABLES_DISPLAYED_CORRECTLY,

to get rid of the '(anonymous namespace)', which is not c++ syntax, thingy fed to the expression parser.
According to rdar://problem/8668674.  It is still marked expectedFailure since the bug has not been fixed.

Johnny Chen e33b166da1 We can do better with the SBValue.linked_list_iter() API by supplying a default
end of list test function as __eol_test__.

The simple example can be reduced to:

    for t in task_head.linked_list_iter('next'):
        print t

Modify the test program to exercise the API for both cases: supplying or not
supplying an end of list test function.

Johnny Chen 6b092e821b The test function to determine whether we have reached the end of the list was
too complex in the test case.  We can just simply test that the SBValue object
is a valid object and it does not correspond to a null pointer in order to say
that EOL has not been reached.

Modify the test case and the lldb.py docstring to have a more compact test
function.

Jason Molenda 26a27fb832 RNBRemote.cpp, RNBRemote.h: Add a new qGetPid packet which returns
the pid of the process currently being debugged by debugserer in
hex, or 0 if unavailable.

This is effectively the same as the qC packet but that packet is
not clear in either its documentation or implementation (in gdb et al)
as to whether it is intended to return a pid or a thread id.  qGetPid
is unambiguous.

If qGetPid is unimplemented in the remote debugserver, the debugger may
try qC and see what kind of value is returned..
