Summary:
This patch updates the last user of ArgInfo::count and deletes
it. I also delete `GetNumInitArguments()` and `GetInitArgInfo()`.
Classess are callables and `GetArgInfo()` should work on them.
On python 3 it already works, of course. `inspect` is good.
On python 2 we have to add yet another special case. But hey if
python 2 wasn't crufty we wouln't need python 3.
I also delete `is_bound_method` becuase it is unused.
This path is tested in `TestStepScripted.py`

Looks like on windows googlemock regexes treat newlines differently
from on darwin. This patch fixes the regex in this test so it
will work on both.

Summary:
With this patch, only the no-argument form of `Reset()` remains in
PythonDataObjects. It also deletes PythonExceptionState in favor of
PythonException, because the only call-site of PythonExceptionState was
also using Reset, so I cleaned up both while I was there.

Summary:
This deletes `Reset(...)`, except for the no-argument form `Reset()`
from `TypedPythonObject`, and therefore from `PythonString`, `PythonList`,
etc.
It updates the various callers to use assignment, `As<>`, `Take<>`,
and `Retain<>`, as appropriate.

Summary:
When users define a debugger command from python, they provide a callable
object. Because the signature of the function has been extended, LLDB
needs to inspect the number of parameters the callable can take.
The rule it was using to decide was weird, apparently not tested, and
giving wrong results for some kinds of python callables.
This patch replaces the weird rule with a simple one: if the callable can
take 5 arguments, it gets the 5 argument version of the signature.
Otherwise it gets the old 4 argument version.
It also adds tests with a bunch of different kinds of python callables
with both 4 and 5 arguments.

Summary:
I'd like to eliminate all forms of Reset() and all public constructors
on these objects, so the only way to make them is with Take<> and Retain<>
and the only way to copy or move them is with actual c++ copy, move, or
assignment.
This is a simple place to start.

Summary:
The current implementation of PythonCallable::GetNumArguments
is not exception safe, has weird semantics, and is just plain
incorrect for some kinds of functions.
Python 3.3 introduces inspect.signature, which lets us easily
query for function signatures in a sane and documented way.
This patch leaves the old implementation in place for < 3.3,
but uses inspect.signature for modern pythons. It also leaves
the old weird semantics in place, but with FIXMEs grousing about
it. We should update the callers and fix the semantics in a
subsequent patch. It also adds some tests.

Summary:
This patch converts FileSystem::Open from this prototype:
Status
Open(File &File, const FileSpec &file_spec, ...);
to this one:
llvm::Expected<std::unique_ptr<File>>
Open(const FileSpec &file_spec, ...);
This is beneficial on its own, as llvm::Expected is a more modern
and recommended error type than Status. It is also a necessary step
towards https://reviews.llvm.org/D67891, and further developments
for lldb_private::File.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and

This patch modifies how we open File instances in LLDB. Rather than
passing a path or FileSpec to the constructor, we now go through the

This is a large API change that removes the two functions from
StreamString that return a std::string& and a const std::string&,
and instead provide one function which returns a StringRef.
Direct access to the underlying buffer violates the concept of
a "stream" which is intended to provide forward only access,
and makes porting to llvm::raw_ostream more difficult in the
future.

*** 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.

and sent up to LLDB and converted to StructuredData, it would not be able to parse the full 64 bit value. A number like 0xf000000000000000L could be placed into a dictionary, and sent to LLDB and it would end up being 0xffffffffffffffff since it would overflow a int64_t. We leave the old code there, but if it overflows, we treat the number like a uint64_t and get it to decode correctly. Added a gtest to cover this so we don't regress. I verified the gtest failed prior to the fix, and it succeeds after it.

This needs to be able to handle bytes, strings, and bytearray objects.
In Python 2 this was easy because bytes and strings are the same thing,
but in Python 3 the 2 cases need to be handled separately. So as not
to mix raw Python C API code with PythonDataObjects code, I've also
introduced a PythonByteArray class to PythonDataObjects to make the
paradigm used here consistent.

This adds PythonTuple and PythonCallable classes to PythonDataObjects.
Additionally, unit tests are provided that exercise this functionality,
including invoking manipulating and checking for validity of tuples,
and invoking and checking for validity of callables using a variety
of different syntaxes.
The goal here is to eventually replace the code in python-wrapper.swig
that directly uses the Python C API to deal with callables and name
resolution with this code that can be more easily tested and debugged.

Python file handling got an overhaul in Python 3, and it affects
the way we have to interact with files. Notably:
1) `PyFile_FromFile` no longer exists, and instead we have to use
`PyFile_FromFd`. This means having a way to get an fd from
a FILE*. For this we reuse the lldb_private::File class to
convert between FILE*s and fds, since there are some subtleties
regarding ownership rules when FILE*s and fds refer to the same
file.
2) PyFile is no longer a builtin type, so there is no such thing as
`PyFile_Check`. Instead, files in Python 3 are just instances
of `io.IOBase`. So the logic for checking if something is a file
in Python 3 is to check if it is a subclass of that module.
Additionally, some unit tests are added to verify that `PythonFile`
works as expected on Python 2 and Python 3, and
`ScriptInterpreterPython` is updated to use `PythonFile` instead of
manual calls to the various `PyFile_XXX` methods.

There were a couple of issues related to string handling that
needed to be fixed. In particular, we cannot get away with
converting `PyUnicode` objects to `PyBytes` objects and storing
the `PyBytes` regardless of Python version. Instead we have to
store a `PyUnicode` on Python 3 and a `PyString` on Python 2.
The reason for this is that if you call `PyObject_Str` on a
`PyBytes` in Python 3, it will return you a string that actually
contains the string value wrappedin the characters b''. So if we
create a `PythonString` with the value "test", and we call Str()
on it, we will get back the string "b'test'", which breaks string
equality. The only way to fix this is to store a native
`PyUnicode` object under Python 3.
With this CL, ScriptInterpreterPythonTests unit tests pass 100%
under Python 2 and Python 3.

PythonObjects were being incorrectly ref-counted. This problem was
pervasive throughout the codebase, leading to an unknown number of memory
leaks and potentially use-after-free.
The issue stems from the fact that Python native methods can either return
"borrowed" references or "owned" references. For the former category, you
*must* incref it prior to decrefing it. And for the latter category, you
should not incref it before decrefing it. This is mostly an issue when a
Python C API method returns a `PyObject` to you, but it can also happen with
a method accepts a `PyObject`. Notably, this happens in `PyList_SetItem`,
which is documented to "steal" the reference that you give it. So if you
pass something to `PyList_SetItem`, you cannot hold onto it unless you
incref it first. But since this is one of only two exceptions in the
entire API, it's confusing and difficult to remember.
Our `PythonObject` class was indiscriminantely increfing every object it
received, which means that if you passed it an owned reference, you now
have a dangling reference since owned references should not be increfed.
We were doing this in quite a few places.
There was also a fair amount of manual increfing and decrefing prevalent
throughout the codebase, which is easy to get wrong.
This patch solves the problem by making any construction of a
`PythonObject` from a `PyObject` take a flag which indicates whether it is
an owned reference or a borrowed reference. There is no way to construct a
`PythonObject` without this flag, and it does not offer a default value,
forcing the user to make an explicit decision every time.
All manual uses of `PyObject` have been cleaned up throughout the codebase
and replaced with `PythonObject` in order to make RAII the predominant
pattern when dealing with native Python objects.

With this change, liblldb is 95% of the way towards being able
to work under both Python 2.x and Python 3.x. This should
introduce no functional change for Python 2.x, but for Python
3.x there are some important changes. Primarily, these are:
1) PyString doesn't exist in Python 3. Everything is a PyUnicode.
To account for this, PythonString now stores a PyBytes instead
of a PyString. In Python 2, this is equivalent to a PyUnicode,
and in Python 3, we do a conversion from PyUnicode to PyBytes
and store the PyBytes.
2) PyInt doesn't exist in Python 3. Everything is a PyLong. To
account for this, PythonInteger stores a PyLong instead of a
PyInt. In Python 2.x, this requires doing a conversion to
PyLong when creating a PythonInteger from a PyInt. In 3.x,
there is no PyInt anyway, so we can assume everything is a
PyLong.
3) PyFile_FromFile doesn't exist in Python 3. Instead there is a
PyFile_FromFd. This is not addressed in this patch because it
will require quite a large change to plumb fd's all the way
through the system into the ScriptInterpreter. This is the only
remaining piece of the puzzle to get LLDB supporting Python 3.x.
Being able to run the test suite is not addressed in this patch.
After the extension module can compile and you can enter an embedded
3.x interpreter, the test suite will be addressed in a followup.
