*** to conform to clang-format’s LLVM style. This kind of mass change has
*** two obvious implications:
Firstly, merging this particular commit into a downstream fork may be a huge
effort. Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit. The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):
find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;
The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.
Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit. There are alternatives available that will attempt
to look through this change and find the appropriate prior commit. YMMV.

Python has a complicated mechanism of checking an objects truthity.
This involves a number of steps, which end with calling two private
methods on an object (if they are implemented). In Python 2 these
two methods are `__nonzero__` and `__len__`, and in Python 3 they
are `__bool__` and `__len__`. Because we *also* define a __len__
method for certain iterable types, this was triggering a situation
in Python 3 where `__nonzero__` wasn't defined, so it was calling
`__len__`, which was returning 0 (for example an SBDebugger with
no targets), and as a result the truthosity was determined to be
False.
We fix this by correctly using ` __bool__` for Python 3, and leave
the behavior under Python 2 unchanged.
Note that this fix is only implemented in the SWIG generation
python script, and not the SWIG generation shell script. Someone
more familiar than me with shell scripts will need to fix them
to support this for Python 3 if desired.

Summary:
This does a broad first pass on cleaning up a lot of the noise when
using pylint on these scripts. It mostly addresses issues of:
* Mixed tabs and spaces.
* Trailing whitespace.
* Semicolons where they aren't needed.
* Incorrect whitespace around () and [].
* Superfluous parentheses.
There will be subsequent patches with further changes that build
upon these.

a watchpoint for either the variable encapsulated by SBValue (Watch) or the pointee
encapsulated by SBValue (WatchPointee).
Removed SBFrame::WatchValue() and SBFrame::WatchLocation() API as a result of that.
Modified the watchpoint related test suite to reflect the change.
Plus replacing WatchpointLocation with Watchpoint throughout the code base.
There are still cleanups to be dome. This patch passes the whole test suite.
Check it in so that we aggressively catch regressions.

from lldbutil.py to the lldb.py proper. The in_range() function becomes a function in
the lldb module. And the symbol_iter() function becomes a method within the SBModule
called symbol_in_section_iter(). Example:
# Iterates the text section and prints each symbols within each sub-section.
for subsec in text_sec:
print INDENT + repr(subsec)
for sym in exe_module.symbol_in_section_iter(subsec):
print INDENT2 + repr(sym)
print INDENT2 + 'symbol type: %s' % symbol_type_to_str(sym.GetType())

Also add rich comparison methods (__eq__ and __ne__) for SBWatchpointLocation.
Modify TestWatchpointLocationIter.py to exercise the new APIs.
Add fuzz testings for the recently added SBTarget APIs related to watchpoint manipulations.
llvm-svn: 140633
to the Python interface.
Implement yet another (threre're 3 now) iterator protocol for SBTarget: watchpoint_location_iter(),
to iterate on the available watchpoint locations. And add a print representation for
SBWatchpointLocation.
Exercise some of these Python API with TestWatchpointLocationIter.py.
llvm-svn: 140595
SBModule supports an additional SBSection iteration, besides the original SBSymbol iteration.
Add docstrings and implement the two SBSection iteration protocols.
llvm-svn: 140449
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.
llvm-svn: 137291
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.

llvm-svn: 137289
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
This patch takes some time because the old Python constructor pattern was not a valid one,
and breaks with SBTypeList's __init__ signature. Oops.
llvm-svn: 136958
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.
llvm-svn: 136144
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.
llvm-svn: 136123
for child in value:
# do something with the child value
and SBValue.linked_list_iter():
for task in task_head.linked_list_iter('next', eol_test):
# visit each item in the linked list
llvm-svn: 136015
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:

of the duty of having SWIG docstring features and multiline string literals
embedded within.
lldb.swig now %include .../SBTarget.i, instead of .../SBTarget.h. Will create
other interface files and transition them over.
Also update modify-python-lldb.py to better handle the trailing blank line right
before the ending '"""' Python docstring delimiter.
llvm-svn: 135355
Add logic to modify-python-lldb to correct swig's transformation of 'char **argv' and 'char **envp'
to 'char argv' and 'char envp' by morphing them into the 'list argv' and 'list envp' (as a list of
Python strings).

Previously the IsValid pattern matched only function signatures of
the form:
def IsValid(*args): ...
However under SWIG 1.3.40 on Linux the signature reads:
def IsValid(self): ...
The new pattern matches both signature types by matching only up to
the left paren.

If two SBAddress's have the same module and file address, they are considered equal.

the class with IsValid() method definition in all possible states.

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())
...
