optionally specify the tty you want to use if you want to use an existing
terminal window by giving a partial or full path name:
(lldb) process launch --tty=ttys002
This would find the terminal window (or tab on MacOSX) that has ttys002 in its
tty path and use it. If it isn't found, it will use a new terminal window.

We now spawn a thread to accept a unix socket connection from the inferior
when it spawns in the terminal, then we launch the process, then we get
the pid back through the unix socket, and then wait for it to SIGSTOP.
darwin-debug now clears the terminal screen and prints out the program and
arguments that are about to be launched.

sockets so the driver doesn't just crash.
Added support for connecting to named sockets (unix IPC sockets) in
ConnectionFileDescriptor.
Modified the Host::LaunchInNewTerminal() for MacOSX to return the process
ID of the inferior process instead of the process ID of the Terminal.app. This
was done by modifying the "darwin-debug" executable to connect to lldb through
a named unix socket which is passed down as an argument. This allows a quick
handshake between "lldb" and "darwin-debug" so we can get the process ID
of the inferior and then attach by process ID and avoid attaching to the
inferior by process name since there could be more than one process with
that name. This still has possible race conditions, those will be fixed
in the near future. This fixes the SIGPIPE issues that were sometimes being
seen when task_for_pid was failing.

"vAttachName;<PROCNAME>" packet, and wait for a new process by name to launch
with the "vAttachWait;<PROCNAME>".
Fixed a few issues with attaching where if DoAttach() returned no error, yet
there was no valid process ID, we would deadlock waiting for an event that
would never happen.
Added a new "process launch" option "--tty" that will launch the process
in a new terminal if the Host layer supports the "Host::LaunchInNewTerminal(...)"
function. This currently works on MacOSX and will allow the debugging of
terminal applications that do complex operations with the terminal.
Cleaned up the output when the process resumes, stops and halts to be
consistent with the output format.

static bool
Host::GetLLDBPath (lldb::PathType path_type, FileSpec &file_spec);
This will fill in "file_spec" with an appropriate path that is appropriate
for the current Host OS. MacOSX will return paths within the LLDB.framework,
and other unixes will return the paths they want. The current PathType
enums are:
typedef enum PathType
{
ePathTypeLLDBShlibDir, // The directory where the lldb.so (unix) or LLDB mach-o file in LLDB.framework (MacOSX) exists
ePathTypeSupportExecutableDir, // Find LLDB support executable directory (debugserver, etc)
ePathTypeHeaderDir, // Find LLDB header file directory
ePathTypePythonDir // Find Python modules (PYTHONPATH) directory
} PathType;
All places that were finding executables are and python paths are now updated
to use this Host call.
Added another new host call to launch the inferior in a terminal. This ability
will be very host specific and doesn't need to be supported on all systems.
MacOSX currently will create a new .command file and tell Terminal.app to open
the .command file. It also uses the new "darwin-debug" app which is a small
app that uses posix to exec (no fork) and stop at the entry point of the
program. The GDB remote plug-in is almost able launch a process and attach to
it, it currently will spawn the process, but it won't attach to it just yet.
This will let LLDB not have to share the terminal with another process and a
new terminal window will pop up when you launch. This won't get hooked up
until we work out all of the kinks. The new Host function is:
static lldb::pid_t
Host::LaunchInNewTerminal (
const char **argv, // argv[0] is executable
const char **envp,
const ArchSpec *arch_spec,
bool stop_at_entry,
bool disable_aslr);
Cleaned up FileSpec::GetPath to not use strncpy() as it was always zero
filling the entire path buffer.
Fixed an issue with the dynamic checker function where I missed a '$' prefix
that should have been added.
llvm-svn: 116690
Added the start of Host specific launch services, though it currently isn't
hookup up to anything. We want to be able to launch a process and use the
native launch services to launch an app like it would be launched by the
user double clicking on the app. We also eventually want to be able to run
a command line app in a newly spawned terminal to avoid terminal sharing.
Fixed an issue with the new DWARF forward type declaration stuff. A crasher
was found that was happening when trying to properly expand the forward
declarations.

to spawn a thread for each process that is being monitored. Previously
LLDB would spawn a single thread that would wait for any child process which
isn't ok to do as a shared library (LLDB.framework on Mac OSX, or lldb.so on
linux). The old single thread used to call wait4() with a pid of -1 which
could cause it to reap child processes that it shouldn't have.
Re-wrote the way Function blocks are handles. Previously I attempted to keep
all blocks in a single memory allocation (in a std::vector). This made the
code somewhat efficient, but hard to work with. I got rid of the old BlockList
class, and went to a straight parent with children relationship. This new
approach will allow for partial parsing of the blocks within a function.
llvm-svn: 111706
Arrange that this then gets properly set on attach, or when a "file" is set.
Add a completer for "process attach -n".
Caveats: there isn't currently a way to handle multiple processes with the same name. That
will have to wait on a way to pass annotations along with the completion strings.

enabled LLVM make style building and made this compile LLDB on Mac OS X. We
can now iterate on this to make the build work on both linux and macosx.
