Chris Bieneman d3199f5ed2 [CMake] Initial support for LLDB.framework
Summary:
This patch adds a CMake option LLDB_BUILD_FRAMEWORK, which builds libLLDB as a macOS framework instead of as a *nix shared library.

With this patch any LLDB executable that has the INCLUDE_IN_FRAMEWORK option set will be built into the Framework's resources directory, and a symlink to the exeuctable will be placed under the build directory's bin folder. Creating the symlinks allows users to run commands from the build directory without altering the workflow.

The framework generated by this patch passes the LLDB test suite, but has not been tested beyond that. It is not expected to be fully ready to ship, but it is a first step.

With this patch binaries that are placed inside the framework aren't being properly installed. Fixing that would increase the patch size significantly, so I'd like to do that in a follow-up.

Todd Fiala 9666ba7526 add stop column highlighting support
This change introduces optional marking of the column within a source
line where a thread is stopped.  This marking will show up when the
source code for a thread stop is displayed, when the debug info
knows the column information, and if the optional column marking is
enabled.

There are two separate methods for handling the marking of the stop
column:

* via ANSI terminal codes, which are added inline to the source line
  display.  The default ANSI mark-up is to underline the column.

* via a pure text-based caret that is added in the appropriate column
  in a newly-inserted blank line underneath the source line in
  question.

There are some new options that control how this all works.

* settings set stop-show-column

  This takes one of 4 values:

  * ansi-or-caret: use the ANSI terminal code mechanism if LLDB
    is running with color enabled; if not, use the caret-based,
    pure text method (see the "caret" mode below).

  * ansi: only use the ANSI terminal code mechanism to highlight
    the stop line.  If LLDB is running with color disabled, no
    stop column marking will occur.

  * caret: only use the pure text caret method, which introduces
    a newly-inserted line underneath the current line, where
    the only character in the new line is a caret that highlights
    the stop column in question.

  * none: no stop column marking will be attempted.

* settings set stop-show-column-ansi-prefix

  This is a text format that indicates the ANSI formatting
  code to insert into the stream immediately preceding the
  column where the stop column character will be marked up.
  It defaults to ${ansi.underline}; however, it can contain
  any valid LLDB format codes, e.g.

      ${ansi.fg.red}${ansi.bold}${ansi.underline}

* settings set stop-show-column-ansi-suffix

  This is the text format that specifies the ANSI terminal
  codes to end the markup that was started with the prefix
  described above.  It defaults to: ${ansi.normal}.  This
  should be sufficient for the common cases.

Significant leg-work was done by Adrian Prantl.  (Thanks, Adrian!)

Todd Fiala ba8a82dbe4 Xcode: support gtests that use the Inputs dir
This change adds support for the gtests that require input data
in the Inputs files.  This is done through a new Xcode script
phase that runs the scripts/Xcode/prepare-gtest-run-dir.sh script.
That script simply copies the contents of all unittests/**/Inputs
dirs into ${TARGET_BUILD_DIR}/Inputs before running the test.

This change also renames the Xcode 'gtest-for-debugging' to
'gtest-build', and makes the gtest "build and run" target
depend on gtest-build.  This reduces replication within the
targets.  gtest .c/.cpp files now should only be added to
the gtest-build target.

Kate Stone b9c1b51e45 *** This commit represents a complete reformatting of the LLDB source code
*** 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.

Enrico Granata 106aae5108 Because of our lifetime rules w.r.t. ValueObjects and ClusterManagers, synthetic children caching is a tricky area:
- if a synthetic child comes from the same hierarchy as its parent object, then it can't be cached by SharedPointer inside the synthetic provider, or it will cause a reference loop;
- but, if a synthetic child is made from whole cloth (e.g. from an expression, a memory region, ...), then it better be cached by SharedPointer, or it will be cleared out and cause an assert() to fail if used at a later point

For most cases of self-rooted synthetic children, we have a flag we set "IsSyntheticChildrenGenerated", but we were not using it to track caching. So, what ended up happening is each provider would set up its own cache, and if it got it wrong, a hard to diagnose crash would ensue

This patch fixes that by centralizing caching in ValueObjectSynthetic - if a provider returns a self-rooted child (as per the flag), then it gets cached centrally by the ValueObject itself
This cache is used only for lifetime management and not later retrieval of child values - a different cache handles that (because we might have a mix of self-rooted and properly nested child values for the same parent, we can't trivially use this lifetime cache for retrieval)

Stephane Sezer 65fd8f4345 Fix FILE * leak in Python API
Summary:
This fixes a leak introduced by some of these changes:
r257644
r250530
r250525

The changes made in these patches result in leaking the FILE* passed
to SetImmediateOutputFile. GetStream() will dup() the fd held by the
python caller and create a new FILE*. It will then pass this FILE*
to SetImmediateOutputFile, which always uses the flag
transfer_ownership=false when it creates a File from the FILE*.

Since transfer_ownership is false, the lldb File destructor will not
close the underlying FILE*. Because this FILE* came from a dup-ed fd,
it will also not be closed when the python caller closes its file.

Leaking the FILE* causes issues if the same file is used multiple times
by different python callers during the same lldb run, even if these
callers open and close the python file properly, as you can end up
with issues due to multiple buffered writes to the same file.

Zachary Turner e867044824 Fix a build issue where the python module could become stale.
We are using hardlinks instead of symlinks, and we attempted to
have some logic where we don't re-create the link if the target
file already exists.  This logic is faulty, however, when you
manually delete the source file (e.g. liblldb.dll) and then rebuild
lldb so that a brand new liblldb.dll gets written.  Now the two files
have different inodes, but the target exists, so we would not remake
the link and the target would become stale.

We fix this by only doing the optimization if they are really the
exact same file (by comparing inode numbers), and if they are not
the same file but the target exists, we delete it and re-create
the link.

Jim Ingham d815c9ab88 Fix SBDebugger.GetOutputFileHandle() on OS X.
The swig typemaps had some magic for output File *'s on OS X that made:

SBDebugger.GetOutputFileHandle() 

actually work.  That was protected by a "#ifdef __MACOSX__", but the corresponding define
got lost going from the Darwin shell scripts to the python scripts for running
swig, so the code was elided.  I need to pass the define to SWIG, but only when
targetting Darwin.

So I added a target-platform argument to prepare_bindings, and if that 
is Darwin, I pass -D__APPLE__ to swig, and that activates this code again, and
GetOutputFileHandle works again.  Note, I only pass that argument for the Xcode
build.  I'm sure it is possible to do that for cmake, but my cmake-foo is weak.

I should have been able to write a test for this by creating a debugger, setting the 
output file handle to something file, writing to it, getting the output file handle 
and reading it.  But SetOutputFileHandle doesn't seem to work from Python, so I'd 
have to write a pexpect test to test this, which I'd rather not do.

Jason Molenda 878ae01889 This patch stops lldb from loading a .lldbinit file from the current
working directory by default -- a typical security problem that we
need to be more conservative about.

It adds a new target setting, target.load-cwd-lldbinit which may
be true (always read $cwd/.lldbinit), false (never read $cwd/.lldbinit)
or warn (warn if there is a $cwd/.lldbinit and don't read it).  The
default is set to warn.  If this is met with unhappiness, we can look
at changing the default to true (to match current behavior) on a 
different platform.

This does not affect reading of ~/.lldbinit - that will still be read,
as before.  If you run lldb in your home directory, it will not warn
about the presence of a .lldbinit file there.

I had to add two SB API - SBHostOS::GetUserHomeDirectory and 
SBFileSpec::AppendPathComponent - for the lldb driver code to be
able to get the home directory path in an OS neutral manner.

The warning text is

There is a .lldbinit file in the current directory which is not being read.
To silence this warning without sourcing in the local .lldbinit,
add the following to the lldbinit file in your home directory:
    settings set target.load-cwd-lldbinit false
To allow lldb to source .lldbinit files in the current working directory,
