Jonas Devlieghere bf03e17c57 [Lldb/Lua] Generate Lua Bindings
This patch uses SWIG to generate the Lua bindings for the SB API. It
covers most of the API, but some methods require a type map similar to
Python.

This is a half-implemented feature that as far as we can tell was

Lawrence D'Anna adbf64ccc9 [LLDB][Python] remove ArgInfo::count
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`

Lawrence D'Anna a69bbe02a2 [LLDB][breakpoints] ArgInfo::count -> ArgInfo::max_positional_args
Summary:
Move breakpoints from the old, bad ArgInfo::count to the new, better
ArgInfo::max_positional_args.   Soon ArgInfo::count will be no more.

It looks like this functionality is already well tested by
`TestBreakpointCommandsFromPython.py`, so there's no need to write

Summary:
Move breakpoints from the old, bad ArgInfo::count to the new, better
ArgInfo::max_positional_args.   Soon ArgInfo::count will be no more.

This functionality is tested in `TestFormatters.py`, `TestDataFormatterSynthVal.py`,

You may notice that the old code was passing 0 arguments when count was 1, and passing
1 argument when count is 2.

This is no longer necessary because max_positional_args counts the self pointer
correctly.

Jim Ingham 738af7a624 Add the ability to pass extra args to a Python breakpoint callback.
For example, it is pretty easy to write a breakpoint command that implements "stop when my caller is Foo", and
    it is pretty easy to write a breakpoint command that implements "stop when my caller is Bar". But there's no
    way to write a generic "stop when my caller is..." function, and then specify the caller when you add the
    command to a breakpoint.

    With this patch, you can pass this data in a SBStructuredData dictionary. That will get stored in
    the PythonCommandBaton for the breakpoint, and passed to the implementation function (if it has the right
    signature) when the breakpoint is hit. Then in lldb, you can say:

    (lldb) break com add -F caller_is -k caller_name -v Foo

    More generally this will allow us to write reusable Python breakpoint commands.

Lawrence D'Anna 2386537c24 [LLDB] bugfix: command script add -f doesn't work for some callables
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.

Jim Ingham c0da1282fc Revert "[lldb] Calculate relative path for symbol links"
This reverts commit 958091c209.

This commit incorrectly sets the _lldb.so symlink (at least it does when
building in Stefans' two build directory mode, where you build llvm with
cmake/ninja and lldb with cmake/Xcode, using a cmake generated project.

The _lldb.so link is SUPPOSED to point to:

bin/LLDB.framework/Versions/A/LLDB

but instead it points to

bin/LLDB

which is where LLDB was staged to before constructing the framework.  This
causes all sorts of problems when we then build the lldb driver into bin -
remember that MacOS is a case-preserving but case insensitive filesystem -
so when we later go to dlopen _lldb.so, we dlopen the main executable instead.

3. ScriptInterpreterPython.cpp where site-packages are added to

This change creates the path once and use it everywhere. So that they

Pavel Labath 0577a0cedb "Fix" TestFileHandle.py on non-darwin platforms
This test exposed a very long standing issue that the python file
objects returned by the FILE* typemap were unusable on non-darwin
platforms. The reason they work on darwin is that they rely on a
non-standard extension to fetch the "mode" of a FILE* object. On other
platforms, this code was #ifdefed out, and so we were returning an empty
mode.

As there's no portable way to get this information, I just change the
non-darwin path to return "r+", which should permit both reading and
writing operations on the object. If the underlying file descriptor
turns out to be incompatible with this mode, the operating system should
return EBADF (or equivalent), instead of the "file not open for XXX"
error from python.

Jonas Devlieghere 7d6a95cf83 prepare_binding_Python: print readable errors if SWIG fails
When swig fails, all the errors are squished onto one line with \n
quoting. It's very hard to read. This will print them out in a more
reasonable format.

Pavel Labath fc1fd6bf9f Fix command-script-import.test on linux
The test was expecting the value of "lldb.frame" to be None, because it
is cleared after each python interpreter session. However, this is not
true in the very first session, because lldb.py sets these values to
invalid objects (lldb.SBFrame(), etc.).

I have not investigated why is it that this test passes on darwin, but
my guess is that this is because we do extra work on darwin (loading the
objc runtime, etc), which causes us to enter the python interpreter
sooner.

This patch changes lldb.py to also initialize these values to None, as
that seems to make more sense. I also fixed some typos in the test while
I was in there.

Haibo Huang 5a115e81cd Fix swig python package path
Summary:
The path defined in CMakeLists.txt doesn't match the path generated in
our python script. This change fixes that.

LLVM_LIBRARY_OUTPUT_INTDIR is defined as:

${CMAKE_BINARY_DIR}/${CMAKE_CFG_INTDIR}/lib${LLVM_LIBDIR_SUFFIX})

On the other hand, the path of site-package is generaged in
get_framework_python_dir_windows() in finishSwigPythonLLDB.py as:
(Dispite its name, the function is used for everything other than xcode)

prefix/cmakeBuildConfiguration/distutils.sysconfig.get_python_lib()

From lldb/CMakeLists.txt, we can see that:
prefix=${CMAKE_BINARY_DIR},
cmakeBuildConfiguration=${CMAKE_CFG_INTDIR}

And from python source code, we can see get_python_lib() always returns
lib/pythonx.y/site-packages for posix, or Lib/site-packages for windows:
https://github.com/python/cpython/blob/3.8/Lib/distutils/sysconfig.py#L128

We should make them match each other.

Jonas Devlieghere 24223eb24c [Python] Implement truth testing for lldb.value
Python 3 calls __bool__() instead of __len__() and lldb.value only
implemented the __len__ method. This adds the __bool__() implementation.
