Zachary Turner 8d48cd6009 Resubmit "Delete the remainder of platform specific code in FileSpec."
This was causing a test failure in one of LLDB's tests which
specifically dealt with a limitation in LLVM's implementation
of home_directory() that LLDB's own implementation had worked
around.

This limitation has been addressed in r298513 on the LLVM side,
so the failing test (which is now unnecessary as the limitation
no longer exists) was removed in r298519, allowing this patch to
be re-submitted without modification.

Zachary Turner 6f9e690199 Move Log from Core -> Utility.
All references to Host and Core have been removed, so this
class can now safely be lowered into Utility.

Zachary Turner bf9a77305f Move classes from Core -> Utility.
This moves the following classes from Core -> Utility.

ConstString
Error
RegularExpression
Stream
StreamString

The goal here is to get lldbUtility into a state where it has
no dependendencies except on itself and LLVM, so it can be the
starting point at which to start untangling LLDB's dependencies.
These are all low level and very widely used classes, and
previously lldbUtility had dependencies up to lldbCore in order
to use these classes.  So moving then down to lldbUtility makes
sense from both the short term and long term perspective in
solving this problem.

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.

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,
set the value of this variable to true.  Only do so if you understand and
accept the security risk.

Ilia K 686b1fe65a Fix FileSpec::GetPath to return null-terminated strings
Summary:
Before this fix the FileSpec::GetPath() returned string which might be without '\0' at the end.
It could have happened if the size of buffer for path was less than actual path.

Test case:
```
FileSpec test("/path/to/file", false);
char buf[]="!!!!!!";
test.GetPath(buf, 3);
```

Before fix:
```
   233          FileSpec test("/path/to/file", false);
   234          char buf[]="!!!!!!";
   235          test.GetPath(buf, 3);
   236
-> 237          if (core_file)
   238          {
   239              if (!core_file.Exists())
   240              {
(lldb) print buf
(char [7]) $0 = "/pa!!!"
```

After fix:
```
   233          FileSpec test("/path/to/file", false);
   234          char buf[]="!!!!!!";
   235          test.GetPath(buf, 3);
   236
-> 237          if (core_file)
   238          {
   239              if (!core_file.Exists())
   240              {
(lldb) print buf
(char [7]) $0 = "/p"
```

Greg Clayton fbb7634934 Expose SBPlatform through the public API.
Example code:

remote_platform = lldb.SBPlatform("remote-macosx"); 
remote_platform.SetWorkingDirectory("/private/tmp")
debugger.SetSelectedPlatform(remote_platform)

connect_options = lldb.SBPlatformConnectOptions("connect://localhost:1111"); 
err = remote_platform.ConnectRemote(connect_options)
if err.Success():
    print >> result, 'Connected to remote platform:'
    print >> result, 'hostname: %s' % (remote_platform.GetHostname())
    src = lldb.SBFileSpec("/Applications/Xcode.app/Contents/SharedFrameworks/LLDB.framework", False)
    dst = lldb.SBFileSpec()
    # copy src to platform working directory since "dst" is empty
    err = remote_platform.Install(src, dst);
    if err.Success():
        print >> result, '%s installed successfully' % (src)
    else:
        print >> result, 'error: failed to install "%s": %s' % (src, err)


Implemented many calls needed in lldb-platform to be able to install a directory that contains symlinks, file and directories.

The remote lldb-platform can now launch GDB servers on the remote system so that remote debugging can be spawned through the remote platform when connected to a remote platform.

The API in SBPlatform is subject to change and will be getting many new functions.

Sean Callanan 9076c0fffb Made all other "operator bool"s explicit and ensured
that all clients use them explicitly.  This will hopefully
prevent any future confusion where things get cast to types

Greg Clayton 226cce2511 Added a way to extract the module specifications from a file. A module specification is information that is required to describe a module (executable, shared library, object file, ect). This information includes host path, platform path (remote path), symbol file path, UUID, object name (for objects in .a files for example you could have an object name of "foo.o"), and target triple. Module specification can be used to create a module, or used to add a module to a target. A list of module specifications can be used to enumerate objects in container objects (like universal mach files and BSD archive files).
There are two new classes:

lldb::SBModuleSpec
lldb::SBModuleSpecList

The SBModuleSpec wraps up a lldb_private::ModuleSpec, and SBModuleSpecList wraps up a lldb_private::ModuleSpecList.

Greg Clayton 5160ce5c72 <rdar://problem/13521159>
LLDB is crashing when logging is enabled from lldb-perf-clang. This has to do with the global destructor chain as the process and its threads are being torn down.

All logging channels now make one and only one instance that is kept in a global pointer which is never freed. This guarantees that logging can correctly continue as the process tears itself down.

Fixed an issues with the SBType and SBTypeMember classes:
- Fixed SBType to be able to dump itself from python
- Fixed SBType::GetNumberOfFields() to return the correct value for objective C interfaces
- Fixed SBTypeMember to be able to dump itself from python
- Fixed the SBTypeMember ability to get a field offset in bytes (the value
  being returned was wrong)
- Added the SBTypeMember ability to get a field offset in bits


Cleaned up a lot of the Stream usage in the SB API files.

Greg Clayton 2d4edfbc6a Modified all logging calls to hand out shared pointers to make sure we
don't crash if we disable logging when some code already has a copy of the
logger. Prior to this fix, logs were handed out as pointers and if they were
held onto while a log got disabled, then it could cause a crash. Now all logs
are handed out as shared pointers so this problem shouldn't happen anymore.
We are also using our new shared pointers that put the shared pointer count
and the object into the same allocation for a tad better performance.
