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

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.
llvm-svn: 138036
- 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.

test cases in TestThreadAPI.py by decorating it with @expectedFailureClang.
Example:

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)
llvm-svn: 138019
- 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
llvm-svn: 137944
- 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
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
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

- 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

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
First, main.c causes a crash, the inferior then gets re-built with main2.c which is not crashing.
Add Base.cleanup(self, dictionary=None) for platform specfic way to do cleanup after build.
This plugin method is used by the above test case to cleanup the main.c build before rebuild for main2.c.
llvm-svn: 137500
The converse is also true: an error is shown when the user tries to add a synthetic provider to a category that already has a filter for the same type
llvm-svn: 137493
*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.
llvm-svn: 137416
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.
llvm-svn: 137338
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)
llvm-svn: 137314
Add code to test case to create an evil linked list with:
task_evil -> task_2 -> task_3 -> task_evil ...
and to check that the linked list iterator only iterates 3 times.

where an empty linked list is represented as a value object with a NULL value, instead of a special value
object which 'points' to NULL.
Also modifies the test case to comply.

Added a testcase that covers both.

Added ProcessModInfo class, to unify "stop_id generation" and "memory modification generation", and use where needed.
llvm-svn: 137102
if your datatype provides synthetic children, "frame variable object[index]" should now do the right thing
in cases where the above syntax would have been rejected before, i.e.
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
synthetic children by name do not work yet

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.

SBTypeList does not have IsValid() method defined. It's always valid in a sense.
So the Python's truth value testing in turn delegates to __len__() method, which
is defined for SBTypeList, and returns 0.
llvm-svn: 136985
Add the rich comparison methods (__eq__, __ne__) to SBType, too.
o lldbtest.py:
Add debug utility method TestBase.DebugSBType().
o test/python_api/type:
Add tests for exercising SBType/SBTypeList API, including the SBTarget.FindTypes(type_name)
API which returns a SBTypeList matching the type_name.
llvm-svn: 136975
And remove expectedFailure decorator for test_SBTypeMember, which no longer exists after the recent changes, replace
it with test_SBTypeList.

There should be nothing unwanted there and a simpe main.cpp (generated from main.cpp.template)

- accordingly, the test cases for the synthetic providers for the std:: containers have been edited to use
${svar%#} instead of ${svar.len} to print out the count of elements ; the .len synthetic child has been
removed from the synthetic providers
The synthetic children providers for the std:: containers now return None when asked for children indexes >= num_children()
Basic code to support filter names based on regular expressions (WIP)
llvm-svn: 136862
The synthetic children providers now use the new (safer) APIs to get the values of objects
As a side effect, fixed an issue in ValueObject where ResolveValue() was not always updating the value before reading it
llvm-svn: 136861
the SBType implementation classes.
Fixed LLDB core and the test suite to not use deprecated SBValue APIs.
Added a few new APIs to SBValue:
int64_t
SBValue::GetValueAsSigned(int64_t fail_value=0);
uint64_t
SBValue::GetValueAsUnsigned(uint64_t fail_value=0)

current context. Previously, if there was a variable
called "self" available, the expression parser
assumed it was inside a method. But class methods
in Objective-C also take a "self" parameter, of DWARF
type "id". We now detect this properly, and only
assume we're in an instance method if "self" is a
pointer to an Objective-C object.
llvm-svn: 136784
- see the test case in lang/objc/objc-dynamic-value for an example
Objective-C dynamic type lookup now works for every Objective-C type
- previously, true dynamic lookup was only performed for type id

Modify lldbbench.py so that lldbtest.line_number() utility function is available to

appropriately between C++ static methods and non-static
methods. This bug made it impossible to call most static
methods, either because Clang did not recognize that a
method could be called without providing a "this"
parameter, or because Clang did not properly mangle the
name of the method when searching for it in the target.
Also added a testcase.
llvm-svn: 136733
Fixed a bug where Objective-C variables coming out of the expression parser could crash the Python synthetic providers:
- expression parser output has a "frozen data" component, which is a byte-exact copy of the value (in host memory),
if trying to read into memory based on the host address, LLDB would crash. we are now passing the correct (target)
pointer to the Python code
Objective-C "id" variables are now formatted according to their dynamic type, if the -d option to frame variable is used:
- Code based on the Objective-C 2.0 runtime is used to obtain this information without running code on the target
llvm-svn: 136695
Stopwatch (self.swatch) within the BenchBase's setUp() instance method to be available
to all the child classes.
Use self.swatch to measure elapsed time in TestRepeatedExprs.py, which needs to be
modified later on to actually measure repeated expression evaluations within the
context of lldb as well as gdb.

while its API clients remain unchanged. The new lldbtest.Base class is to capture common behaviors
when working with the test driver to accomplish things. The clients of lldbtest.Base can be
lldb command line and api tests as well as other generic tests like a benchmark test.
llvm-svn: 136636
The test driver now takes an option "+b" which enables to run just the benchmarks tests.
By default, tests decorated with the @benchmarks_test decorator do not get run.

- 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

too complex in the test case. We can just simply test that the SBValue object

to iterate through an SBValue instance by treating it as the head of a linked
list. API program must provide two args to the linked_list_iter() method:
the first being the child member name which points to the next item on the list
and the second being a Python function which an SBValue (for the next item) and
returns True if end of list is reached, otherwise it returns False.
For example, suppose we have the following sample program.
#include <stdio.h>
class Task {
public:
int id;
Task *next;
Task(int i, Task *n):
id(i),
next(n)
{}
};
int main (int argc, char const *argv[])
{
Task *task_head = new Task(-1, NULL);
Task *task1 = new Task(1, NULL);
Task *task2 = new Task(2, NULL);
Task *task3 = new Task(3, NULL); // Orphaned.
Task *task4 = new Task(4, NULL);
Task *task5 = new Task(5, NULL);
task_head->next = task1;
task1->next = task2;
task2->next = task4;
task4->next = task5;
int total = 0; // Break at this line
Task *t = task_head;
while (t != NULL) {
if (t->id >= 0)
++total;
t = t->next;
}
printf("We have a total number of %d tasks\n", total);
return 0;
}
The test program produces the following output while exercising the linked_list_iter() SBVAlue API:
task_head:
TypeName -> Task *
ByteSize -> 8
NumChildren -> 2
Value -> 0x0000000106400380

- 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)

API.
SBTarget changes include changing:
bool
SBTarget::ResolveLoadAddress (lldb::addr_t vm_addr,
lldb::SBAddress& addr);
to be:
lldb::SBAddress
SBTarget::ResolveLoadAddress (lldb::addr_t vm_addr);
SBAddress can how contruct itself using a load address and a target
which can be used to resolve the address:
SBAddress (lldb::addr_t load_addr, lldb::SBTarget &target);
This will actually just call the new SetLoadAddress accessor:
void
SetLoadAddress (lldb::addr_t load_addr,
lldb::SBTarget &target);
This function will always succeed in making a SBAddress object
that can be used in API calls (even if "target" isn't valid).
If "target" is valid and there are sections currently loaded,
then it will resolve the address to a section offset address if
it can. Else an address with a NULL section and an offset that is
the "load_addr" that was passed in. We do this because a load address
might be from the heap or stack.
llvm-svn: 135770
(e.g. ${var%S}). this might already be the default if your variable is of an aggregate type
new feature: synthetic filters. you can restrict the number of children for your variables to only a meaningful subset
- the restricted list of children obeys the typical rules (e.g. summaries prevail over children)
- one-line summaries show only the filtered (synthetic) children, if you type an expanded summary string, or you use Python scripts, all the real children are accessible
- to provide a synthetic children list use the "type synth add" command, as in:
type synth add foo_type --child varA --child varB[0] --child varC->packet->flags[1-4]
(you can use ., ->, single-item array operator [N] and bitfield operator [N-M]; array slice access is not supported, giving simplified names to expression paths is not supported)
- a new -S option to frame variable and target variable lets you override synthetic children and instead show real ones
llvm-svn: 135731
Code cleanup:
- The Format Manager implementation is now split between two files: FormatClasses.{h|cpp} where the
actual formatter classes (ValueFormat, SummaryFormat, ...) are implemented and
FormatManager.{h|cpp} where the infrastructure classes (FormatNavigator, FormatManager, ...)
are contained. The wrapper code always remains in Debugger.{h|cpp}
- Several leftover fields, methods and comments from previous design choices have been removed
type category subcommands (enable, disable, delete) now can take a list of category names as input
- for type category enable, saying "enable A B C" is the same as saying
enable C
enable B
enable A
(the ordering is relevant in enabling categories, and it is expected that a user typing
enable A B C wants to look into category A, then into B, then into C and not the other
way round)
- for the other two commands, the order is not really relevant (however, the same inverted ordering
is used for consistency)
llvm-svn: 135494
The "systemwide summaries" feature has been removed and replaced with a more general and
powerful mechanism.
Categories:
- summaries can now be grouped into buckets, called "categories" (it is expected that categories
correspond to libraries and/or runtime environments)
- to add a summary to a category, you can use the -w option to type summary add and give
a category name (e.g. type summary add -f "foo" foo_t -w foo_category)
- categories are by default disabled, which means LLDB will not look into them for summaries,
to enable a category use "type category enable". once a category is enabled, LLDB will
look into that category for summaries. the rules are quite trivial: every enabled category
is searched for an exact match. if an exact match is nowhere to be found, any match is
searched for in every enabled category (whether it involves cascading, going to base classes,
...). categories are searched into the order in which they were enabled (the most recently
enabled category first, then the second most and so on..)
- by default, most commands that deal with summaries, use a category named "default" if no
explicit -w parameter is given (the observable behavior of LLDB should not change when
categories are not explicitly used)
- the systemwide summaries are now part of a "system" category
llvm-svn: 135463
- help type summary add now gives some hints on how to use it
frame variable and target variable now have a --no-summary-depth (-Y) option:
- simply using -Y without an argument will skip one level of summaries, i.e.
your aggregate types will expand their children and display no summary, even
if they have one. children will behave normally
- using -Y<int>, as in -Y4, -Y7, ..., will skip as many levels of summaries as
given by the <int> parameter (obviously, -Y and -Y1 are the same thing). children
beneath the given depth level will behave normally
-Y0 is the same as omitting the --no-summary-depth parameter entirely
This option replaces the defined-but-unimplemented --no-summary
llvm-svn: 135336
- Summaries for char*, const char* and char[] are loaded at startup as
system-wide summaries. This means you cannot delete them unless you use
the -a option to type summary delete/clear
- You can add your own system-wide summaries by using the -w option to type
summary add
Several code improvements for the Python summaries feature
llvm-svn: 135326
represent pointers and arrays by adding an extra parameter to the
SBValue
SBValue::GetChildAtIndex (uint32_t idx,
DynamicValueType use_dynamic,
bool can_create_synthetic);
The new "can_create_synthetic" will allow you to create child values that
aren't actually a part of the original type. So if you code like:
int *foo_ptr = ...
And you have a SBValue that contains the value for "foo_ptr":
SBValue foo_value = ...
You can now get the "foo_ptr[12]" item by doing this:
v = foo_value.GetChiltAtIndex (12, lldb.eNoDynamicValues, True);
Normall the "foo_value" would only have one child value (an integer), but
we can create "synthetic" child values by treating the pointer as an array.
Likewise if you have code like:
int array[2];
array_value = ....
v = array_value.GetChiltAtIndex (0); // Success, v will be valid
v = array_value.GetChiltAtIndex (1); // Success, v will be valid
v = array_value.GetChiltAtIndex (2); // Fail, v won't be valid, "2" is not a valid zero based index in "array"
But if you use the ability to create synthetic children:
v = array_value.GetChiltAtIndex (0, lldb.eNoDynamicValues, True); // Success, v will be valid
v = array_value.GetChiltAtIndex (1, lldb.eNoDynamicValues, True); // Success, v will be valid
v = array_value.GetChiltAtIndex (2, lldb.eNoDynamicValues, True); // Success, v will be valid
llvm-svn: 135292
- 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
The reasom of the crash is because of a missing entry in the argument table corresponding to eArgTypeUnsignedInteger.
Add such entry and modify the call site of the crash to go through a fail-fast API to retrieve the argument table.
Add a regression test to TestHelp.py.
llvm-svn: 135206
clang/gcc/llvm-gcc. If the first breakpoint is due to stop at an inlined
frame, test that the call site corresponds to where it should be. Also add
an expecr for a second break stop, if the first break stop corresponds to an
inlined call frame #0.
rdar://problem/9741470
llvm-svn: 135100
- formats %s %char[] %c and %a now work to print 0-terminated c-strings if they are applied to a char* or char[] even without the [] operator (e.g. ${var%s})
- array formats (char[], intN[], ..) now work when applied to an array of a scalar type even without the [] operator (e.g. ${var%int32_t[]})
LLDB will not crash because of endless loop when trying to obtain a summary for an object that has no value and references itself in its summary string
In many cases, a wrong summary string will now display an "<error>" message instead of giving out an empty string
llvm-svn: 135007
- a new --name option for "type summary add" lets you give a name to a summary
- a new --summary option for "frame variable" lets you bind a named summary to one or more variables
${var%s} now works for printing the value of 0-terminated CStrings
type format test case now tests for cascading
- this is disabled on GCC because GCC may end up stripping typedef chains, basically breaking cascading
new design for the FormatNavigator class
new template class CleanUp2 meant to support cleanup routines with 1 additional parameter beyond resource handle
llvm-svn: 134943
is just wrong and resulted in the inferior's output getting mixed into the GDB remote communication's
log file. Change all test cases to not pass os.ctermid() and either use SBTarget.LaunchSimple() or
SBTarget.Launch() and pass None as stdin_path/stdout_path/srderr_path to use a pseudo terminal.
rdar://problem/9716499 program output is getting mixed into the GDB remote communications
llvm-svn: 134940
before issuing API calls to find the global variable and to get its value.
rdar://problem/9700873 has been updated to reflect the latest status. The dwarf case
now does not seg fault if the inferior is not started; instead, for dwarf case, the
value retrieved from the global variable is None.
llvm-svn: 134909
Add a usage example of SBEvent APIs.
o SBEvent.h and SBListener.h:
Add method docstrings for SBEvent.h and SBListener.h, and example usage of SBEvent into
the class docstring of SBEvent.
o lldb.swig:
Add typemap for SBEvent::SBEvent (uint32_t event, const char *cstr, uint32_t cstr_len)
so that we can use, in Python, obj2 = lldb.SBEvent(0, "abc") to create an SBEvent.
llvm-svn: 134766
new GetValueForExpressionPath() method in ValueObject to navigate expression paths in a more bitfield vs slices aware way
changes to the varformats.html document (WIP)
llvm-svn: 134679
group class: OptionGroupVariable. It gets initialized with
a boolean that indicates if the frame specific options are
included so that this can be used in both the "frame variable"
and "target variable" commands.
Removed the global functionality from the "frame variable"
command. Users should switch to using the "target variable"
command.
llvm-svn: 134594
would return instead of a less than helpful "name: '%s'" description.
Make sure that when we ask for the error from a ValueObject object we
first update the value if needed.
Cleaned up some SB functions to use internal functions and not re-call
through the public API when possible.
llvm-svn: 134497
- ${*expr} now simply means to dereference expr before actually using it
- bitfields, array ranges and pointer ranges now work in a (hopefully) more natural and language-compliant way
a new class TypeHierarchyNavigator replicates the behavior of the FormatManager in going through type hierarchies
when one-lining summary strings, children's summaries can be used as well as values
llvm-svn: 134458
- type names can now be regular expressions (exact matching is done first, and is faster)
- integral (and floating) types can be printed as bitfields, i.e. ${var[low-high]} will extract bits low thru high of the value and print them
- array subscripts are supported, both for arrays and for pointers. the syntax is ${*var[low-high]}, or ${*var[]} to print the whole array (the latter only works for statically sized arrays)
- summary is now printed by default when a summary string references a variable. if that variable's type has no summary, value is printed instead. to force value, you can use %V as a format specifier
- basic support for ObjectiveC:
- ObjectiveC inheritance chains are now walked through
- %@ can be specified as a summary format, to print the ObjectiveC runtime description for an object
- some bug fixes
llvm-svn: 134293
"struct ", "class ", and "union " from the start of any type names that are
extracted from clang QualType objects. I had to fix test suite cases that
were expecting the struct/union/class prefix to be there.
llvm-svn: 134132
implements three commands:
type summary add <format> <typename1> [<typename2> ...]
type summary delete <typename1> [<typename2> ...]
type summary list [<typename1> [<typename2>] ...]
type summary clear
This allows you to specify the default format that will be used to display
summaries for variables, shown when you use "frame variable" or "expression", or the SBValue classes.
Examples:
type summary add "x = ${var.x}" Point
type summary list
type summary add --one-liner SimpleType
llvm-svn: 134108
Fixed crashes for SBValue fuzz calls.
And change 'bool SBType::IsPointerType(void)' to
'bool SBType::IsAPointerType(void)' to avoid name collision with the static 'bool SBType::IsPointerType(void *)'
function, which SWIG cannot handle.
llvm-svn: 134096
Test "print object" where another thread blocks the print object from making progress.
Set a breakpoint on the line in my_pthread_routine. Then switch threads
to the main thread, and do print the lock_me object. Since that will
try to get the lock already gotten by my_pthread_routime thread, it will
have to switch to running all threads, and that should then succeed.
llvm-svn: 133933
Assign the test method name to self.testMethodName. This can be useful for the
test directory (see test/types for a good example) which houses a bunch of executables
compiled from different source files. The default build action is to create a.out as
the binary executable, which can confuse the module cacheing mechanism and result in
the debugger getting a stale image as the target to be debugged, and chaos ensues.
o AbstractBase.py, TestThreadAPI.py:
Use self.testMethodName to our advantage.
o TestLoadUnload.py:
Add expected failure marker to test case test_modules_search_paths().
llvm-svn: 133768
employ different executable names when creating the target for lldb to debug.
Comparing the log files for the same test case with success/failure results show
that the failed one was setting the breakpoint on some different address than the
succeeded one, leading us to suspect that the file system maybe think it knows better
and caches the wrong executable file (they were all named 'a.out' before) which lldb
subsequently reads from.
Now './dotest.py -v types' passes without specifying the '-w' option.

if not already specified by the test driver (via ./dotest -w). Remove the AbstractBase.setUp()
method definition when/if we find out the cause of the failures if no delays are inserted
between these test cases.
llvm-svn: 133495
We still have the the issue where running:
./dotest.py -v types
we have test failures where the inferior either runs to exited with status 0 or
the inferior stops but not because of breakpoint (for example):
runCmd: process status
output: Process 90060 stopped
* thread #1: tid = 0x2d03, 0x000000010000e2ca, stop reason = EXC_BAD_ACCESS (code=2, address=0x10000e2ca)
frame #0: 0x000000010000e2ca
There are two cases where the inferior stops for the breakpoint (good), but the expression parser
prints out the wrong information. The two failures are:
Failure-TestFloatTypesExpr.FloatTypesExprTestCase.test_double_type_with_dsym.log
Failure-TestFloatTypesExpr.FloatTypesExprTestCase.test_double_type_with_dwarf.log
I'll file a radar on the two expression parser misbehave, while continue investigating why the
inferior stops for the wrong reason or does not stop at all.
For now, you'll need to do:
./dotest.py -v -w types
llvm-svn: 133488
after initial construction.
There are two exceptions to the above general rules, though; the API objects are
SBCommadnReturnObject and SBStream.
llvm-svn: 133475
Among them are test cases to exercise SBTarget.AttachToProcessWithName(); we attach to "hello_world",
and verify that, after attachment, the currently selected target indeed matches "hello_world".
llvm-svn: 133279
Add a test case for the SBTarget::AttachToProcessWithID() API call.
o main.c:
The change goes with the added test case test_with_dwarf_and_attach_to_process_with_id_api() above.
o SBTarget.cpp:
Checks whether we're in synchronous mode. If yes, let's wait for the process to stop right after attaching.
llvm-svn: 133223
For the print_stacktrace(thread, string_buffer = False) function, if we have debug info
for a frame function, let's also emit the args for the current function.
o TestFrameUtils.py:
Add stronger assertTrue for frame0's args.
o TestPrintStackTraces.py:
Launch the inferior with ["abc", "xyz"] and expect '(int)argc=3' in the stack traces, since
by design the inferior is built with debug info.
llvm-svn: 133204
remove the self.runStarted attribute since the automatic shutdown of processes associated
with the targets are now performed automatically.
llvm-svn: 133092
bool SBDebugger::DeleteTarget(lldb::SBTarget &target);
which is used in the test tearDown() phase to cleanup the debugger's target list
so that it won't grow larger and larger as test cases are executed. This is also
a good opportunity to get rid of the arcane requirement that test cases exercising
the Python API must assign the process object to self.process so that it gets
shutdown gracefully. Instead, the shutdown of the process associated with each
target is now being now automatically.
Also get rid of an API from SBTarget class:
SBTarget::DeleteTargetFromList(lldb_private::TargetList *list);
llvm-svn: 133091
If two SBAddress's have the same module and file address, they are considered equal.
Add a test snippet 'sa1 == sa2' to exercise the rich comparison methods for SBAddress.
llvm-svn: 132807
those lldb objects which implement the IsValid() method, let's change the rest of
the test suite to use the more compact truth value testing pattern (the Python way).
llvm-svn: 131970
object.__nonzero__(self) is called to implement truth value testing and the built-in operation bool(),
via a simple delegation to self.IsValid().
Change tests under python_api/lldbutil to utilize this mechanism.
llvm-svn: 131494
unambiguous iteration support. So that we could, for example:
...
REGs = lldbutil.get_GPRs(frame)
print "Number of general purpose registers: %d" % len(REGs)
for reg in REGs:
print "%s => %s" %(reg.GetName(), reg.GetValue())
...
llvm-svn: 131418
representing variables whose type must be inferred
from the way they are used. Functions without debug
information now return UnknownAnyTy and must be cast.
Variables with no debug information are not yet using
UnknownAnyTy; instead they are assumed to be void*.
Support for variables of unknown type is coming (and,
in fact, some relevant support functions are included
in this commit) but will take a bit of extra effort.
The testsuite has also been updated to reflect the new
requirement that the result of printf be cast, i.e.
expr (int) printf("Hello world!")
llvm-svn: 131263
o get_parent_frame(frame)
o get_args_as_string(frame)
to lldbutil.py and create TestFrameUtils.py to exercise the utils.
Plus re-arrange the test/python_api/lldbutil to have three directories
for testing iteration, process stack traces, and the just added frame utils.
llvm-svn: 131213
compile unit, which has an external reference to symbols defined in foo.m, the type query:
in this case, 'expression (NSArray*)array_token'
continues to work.
This test is to accompany http://llvm.org/viewvc/llvm-project?rev=131145&view=rev.
llvm-svn: 131154
Also add three convenience functions get_GPRs(frame), get_FPRs(frame), and get_ESRs(frame) to get the general
purpose registers, the floating point registers, and the exception state registers.
Add TestRegistersIterator.py to test these added functions of lldbutil.py.
