Greg Clayton 32720b51e2 <rdar://problem/9731573> 
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.

- don't strip too many frames from the backtrace when logging close backtraces
- cleanup some logging messages

When the lldb_private::Debugger goes away, it should cleanup all

Sean Callanan cbbe3ac4a9 I made two major improvements to the way the 
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.

Sean Callanan ba5be17e7d Only create new ASTImporters on demand, not 
proactively.

 2012-01-13 22:19:53 +00:00
Sean Callanan 7282e2acf4 If the name of a struct or union is NULL in the 
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.

llvm-svn: 148111
 2012-01-13 08:41:20 +00:00
Greg Clayton 6d3dbf5161 Added a new thread and frame format that can be used to display a function 
name + arguments when the data is available. It seems to work really well, 
but some more testing is needed before we make this on by default.

The new function format name is:

 ${function.name-with-args}

To see how to use these formats see the website:

    http://lldb.llvm.org/formats.html

Here is a sample backtrace of debugging LLDB with LLDB using this new format
value:

Greg Clayton 44435ed07a Big change in the way ObjectFile file contents are managed. We now 
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
object file data much easier to manage and we don't end up opening the
file, reading some data and closing the file over and over.

SBProcess.GetSTDERR() not getting stderr of the launched process

Since we are launch the inferior with:

Jim Ingham f714d3d7f2 As we are grubbing through memory chasing down the hierarchy of an ObjC object, protect against the possibility that that object might be just random memory with loops.

Greg Clayton 7d7850af64 Since clang modifies .o files in place, use MAP_PRIVATE as it seems 
to fix the issues we run into on darwin even though the docs don't
seems to say it will.

Jim Ingham aa1bc80f5d Don't call lldb_private::Process::GetLoadAddressPermissions to sanity check the unwind addresses 
when you already know that the address is contained in a bona fide function.  This can be a 
slow call.

Johnny Chen c256b99a17 Refactor the test/types directory to reduce some stupid reduant code. 
Also add test cases to the test suite to exercise displaying of variables captured inside a block (Darwin-only).

Johnny Chen beac8f991f Add a CFLAGS_EXTRAS make variable to be able to pass things (like '-DTEST_BLOCK_CAPTURED_VARS') to the compile phase. 
Plus add a DYLIB_ONLY make variable that can be used to turn off compilation/building of a.out. Example:

[16:39:21] johnny:/Volumes/data/lldb/svn/trunk/test/lang/c/global_variables $ make clean
rm -rf "a.out" "a.out.dSYM"  main.o main.d a.o a.d liba.dylib liba.dylib.dSYM
[16:39:24] johnny:/Volumes/data/lldb/svn/trunk/test/lang/c/global_variables $ make DYLIB_ONLY=YES
clang -gdwarf-2 -O0   -arch x86_64   -c -o a.o a.c
clang -gdwarf-2 -O0   -arch x86_64  a.o -install_name "@executable_path/liba.dylib" -dynamiclib -o "liba.dylib"

Greg Clayton 33289908f9 Added a file descriptor interposing library for darwin. This can catch all 
functions that can create file descriptors and close them. It will warn when
there close file descriptor call that returns with EBADF and show the 
corresponding stack backtraces that caused the issue. It will also log all
file descriptor create and delete calls. See the comments at the top of
FDInterposing.cpp for all of the details.
