Summary:
It's really annoying and confusing to have to keep referring
back to earlier versions of this SBFile work to find the
tests that need to be added for each patch, and not duplicate
them with new tests.
This patch just imports all my tests. A bunch of them don't
work yet, so they are marked to be skipped. They'll be
unmarked as I fix them.
One of these tests will actually trip an assert in the SWIG
code now instead of just failing, so I'm fixing that here too.

Summary:
This patch adds SWIG typemaps that can convert arbitrary python
file objects into lldb_private::File.
A SBFile may be initialized from a python file using the
constructor. There are also alternate, tagged constructors
that allow python files to be borrowed, and for the caller
to control whether or not the python I/O methods will be
called even when a file descriptor is available.I

Summary:
SBFile is a scripting API wrapper for lldb_private::File
This is the first step in a project to enable arbitrary python
io.IOBase file objects -- including those that override the read()
and write() methods -- to be used as the main debugger IOStreams.
Currently this is impossible because python file objects must first
be converted into FILE* streams by SWIG in order to be passed into
the debugger.

potentially dangerous overrides and updates of variables like CFLAGS
with safe assignments to variables reserved for this purpose like
CFLAGS_EXTRAS.

Jim pointed out that the LLDB global variables should only be available
in interactive mode. When used from a command for example, their values
might be stale or not at all what the user expects. Therefore we want to
explicitly make these variables unavailable.

Summary:
This patch adds support of watchpoints to the old `ProcessWindows` plugin.
The `ProcessWindows` plugin uses the `RegisterContext` to set and reset
watchpoints. The `RegisterContext` has some interface to access watchpoints,
but it is very limited (e.g. it is impossible to retrieve the last triggered
watchpoint with it), that's why I have implemented a slightly different
interface in the `RegisterContextWindows`. Moreover, I have made the
`ProcessWindows` plugin responsible for search of a vacant watchpoint slot,
because watchpoints exist per-process (not per-thread), then we can place
the same watchpoint in the same slot in different threads. With this scheme
threads don't need to have their own watchpoint lists, and it simplifies
identifying of the last triggered watchpoint.

Summary:
It seems this was an unintended side-effect of D26698. AFAICT, these
functions did return an empty string before that patch, and the patch
contained code which attempted to ensure that, but those efforts were
negated by ConstString::AsCString, which by default returns a nullptr
even for empty strings.
This patch:
- fixes the GetOutput/Error methods to really return empty strings
- adds and explicit test for that
- removes a workaround in lldbtest.py, which was masking this problem
from our other tests

It looks like when this test was added, it was based on TestHelloWorld and it ended up with the same class name. This is an issue because the logs associated with the tests use the class name as the identifier for the file and if two tests have the same name their logs overwrite each other. On non-windows, this just means we lose one of the logs, but on Windows this means that one of the tests will fail occasionally because the file are locked by the other test.

While this fixed the windows bot failures, it also broke all other bots.
Upon closer inspection, it turns out that the windows bots were "broken"
because two tests were unexpectedly passing -- i.e., the original patch
(r360375) actually improved our stepping support on windows.
So instead, I remove the relevant XFAILs.
This reverts commit r360397.
llvm-svn: 360407
This test contained an incredibly complicated inferior, but in reality,
all it was testing was that we can backtrace up to main and see main's
arguments.
However, the way this was implemented (setting a breakpoint on a
separate thread) meant that each time the test would run, it would stop
in a different location on the main thread. Most of the time this
location would be deep in some libc function, which meant that the
success of this test depended on our ability to backtrace out of a
random function of the c library that the user happens to have
installed.
This makes the test unpredictable. Backtracing out of a libc function is
an important functionality, but this is not the way to test it. Often it
is not even our fault that we cannot backtrace out because the C library
contains a lot of assembly routines that may not have correct unwind
info associated with them.
For this reason the test has accumulated numerous @expectedFail/Flaky
decorators. In this patch, I replace the inferior with one that does not
depend on libc functions. Instead I create a couple of stack frames of
user code, and have the test verify that. I also simplify the test by
using lldbutil.run_to_source_breakpoint.

Summary:
Instead of modifying the swig-generated code, just add the appropriate
methods to the interface files in order to get the swig to do the
generation for us.
This is a straight-forward move from the python script to the interface
files. The single class which has nontrivial handling in the script
(SBModule) has been left for a separate patch.
For the cases where I did not find any tests exercising the
iteration/length methods (i.e., no tests failed after I stopped emitting
them), I tried to add basic tests for that functionality.

Add a convenience 'expectedFailureNetBSD' decorator and mark all tests
currently failing on NetBSD with it. Also skip a few tests that hang

catch regressions while we still have a lot of work to do to get tests
working.
It seems that there are also some flaky tests. I am going to address
them later on.

Summary:
Instead of doing string chopping on the resulting python file, get swig
to output the version for us. The two things which make slightly
non-trivial are:
- in order to get swig to expand SWIG_VERSION for us, we cannot use
%pythoncode directly, but we have to go through an intermediate macro.
- SWIG_VERSION is a hex number, but it's components are supposed to be
interpreted decimally, so there is a bit of integer magic needed to
get the right number to come out.
I've tested that this approach works both with the latest (3.0.12) and
oldest (1.3.40) supported swig.

to reflect the new license.
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
repository.
