where we changed the CommandObjectSettingsSet object impl to require raw command string.

Do the same for CommandObjectSettingsAppend/InsertBefore/InsertAfter classes and
add test cases for basic functionalities as well as for variable name completion.

A Small tweak to handle a zero timeout.

llvm-svn: 148617

we didn't implement that in setting the socket option.
<rdar://problem/10711649>

llvm-svn: 148616

where we changed the CommandObjectSettingsSet object impl to require raw command string.

Do the same for CommandObjectSettingsReplace class and add two test cases; one for
the "settings replace" command and the other to ensure that completion for variable
name still works. 

llvm-svn: 148615

Release more stuff in Process::Destroy().

llvm-svn: 148597

  Fix a bug where "settings set -r th" wouldn't complete.

o UserSettingsController.cpp:

  Fix a bug where "settings set target.process." wouldn't complete.

o test/functionalities/completion:

  Add various completion test cases related to 'settings set' command.

llvm-svn: 148596

Add comment describing the interaction of WantsRawCommandString()/WantsCompletion() with the completion mechanism.

We should ultimately introduce GetAs...Type

Fixed an issue where backtick char is not properly honored when setting the frame-format variable, like the following:

(lldb) settings set frame-format frame #${frame.index}: ${frame.pc}{ ${module.file.basename}{`${function.name-with-args}${function.pc-offset}}}{ at ${line.file.basename}:${line.number}}\n
(lldb) settings show frame-format
frame-format (string) = "frame #${frame.index}: ${frame.pc}{ `${module.file.basename}{${function.name-with-args}${function.pc-offset}}}{` at ${line.file.basename}:${line.number}}\n"
(lldb)

o CommandObjectSettings.h/.cpp:

  Modify the command object impl to require raw command string instead of parsed command string,
  which also fixes an outstanding issue that customizing the prompt with trailing spaces doesn't
  work.

o Args.cpp:

  During CommandInterpreter::HandleCommand(), there is a PreprocessCommand phase which already
  strips/processes pairs of backticks as an expression eval step.  There's no need to treat
  a backtick as starting a quote.

o TestAbbreviations.py and change_prompt.lldb:

  Fixed incorrect test case/logic.

o TestSettings.py:

  Remove expectedFailure decorator.

llvm-svn: 148413

Fixed two double "int close(int fd)" issues found by our file descriptor
interposing library on darwin:

The first is in SBDebugger::SetInputFileHandle (FILE *file, bool transfer_ownership)
where we would give our FILE * to a lldb_private::File object member variable and tell
it that it owned the file descriptor if "transfer_ownership" was true, and then we
would also give it to the communication plug-in that waits for stdin to come in and
tell it that it owned the FILE *. They would both try and close the file.

The seconds was when we use a file descriptor through ConnectionFileDescriptor 
where someone else is creating a connection with ConnectionFileDescriptor and a URL
like: "fd://123". We were always taking ownwership of the fd 123, when we shouldn't
be. There is a TODO in the comments that says we should allow URL options to be passed
to be able to specify this later (something like: "fd://123?transer_ownership=1"), but
we can get to this later.

When the lldb_private::Debugger goes away, it should cleanup all
of its targets.

master AST importer imports types.

- First, before importing the definition of a
  Decl from its source, notify the underlying
  importer of the source->destination mapping.
  Especially for anonymous strucutres that are
  otherwise hard to unique in the target AST
  context, this hint is very helpful.

- When deporting a type or Decl from one
  ASTContext to another (deporting occurs in
  the case of moving result types from the
  parser's AST context to the result AST
  context), don't forget their origin if the
  origin is the original debug information.

debug info, call it anonymous.  This isn't
perfect, because Clang actually considers the
following struct not to be anonymous:
–
struct {
  int x;
  int y;
} g_foo;

but DWARF doesn't make the distinction.

but some more testing is needed before we make this on by default.

Discriminate between the lldb_private::Type's for ObjC Classes that come from debug info, and those that

mmap() the entire object file contents into memory with MAP_PRIVATE.
We do this because object file contents can change on us and currently
this helps alleviate this situation. It also make the code for accessing
