lldb/tools/debugserver/source/ChangeLog

2010-01-29  Greg Clayton  <gclayton@apple.com>

	* MachProcess.cpp (MachProcess::PrepareForAttach): No longer use the

	so debugserver can be sandboxed.

	* MachTask.cpp (MachTask::GetDYLDAllImageInfosAddress): Hack around bad
	kernel code that renamed the first member of the TASK_DYLD_INFO without
	any way to detect it has changed.

	debug session go for a little bit and then later failing after a few more
	packets.

	dependency ala NO_ACKS.

	* RNBSocket.h (RNBSocket::RNBSocket): Take either a port # or
	an already-opened socket, with a boolean to indicate which it is.
	* RNBRemote.cpp (RNBRemote::RNBRemote): Ditto.
	* RNBRemote.h: Prototype update.
	* test-remotenub.cpp: Include lockdown.h.  Take --lockdown command
	line arg, get the socket from liblockdown.dylib instead of opening
	our own socket if it is specified.  --lockdown indicates that 
	the program name/args will be provided via remote protocol instead
	of on the command line.

	* RNBRemote.cpp: Add NO_ACKS #ifdefs around code that computes
	the checksums and sends/expects the gdb remote protocol ACK packets.
	If NO_ACKS is defined, debugserver will not send or expect acks.
	* test-remotenub.cpp (main): Print a different version string
	if NO_ACKS is defined.

	* PThreadEvent.cpp: Added this pointer to all logging calls.

2008-01-16  Greg Clayton  (gclayton@apple.com)

	* RNBSocket.cpp (RNBSocket::Connect()): Use TCP so we can try the
	TCP_NODELAY socket option.
	(RNBSocket::SetSocketOption()): New function.
	* RNBSocket.h (RNBSocket::SetSocketOption()): New class function.

2008-01-14  Jason Molenda  (jmolenda@apple.com)

	* RNBRemote.cpp (RNBRemote::HandlePacket_last_signal): When printing
	registers, skip over gdb regs which don't map to DNB regs.

2008-01-14  Jim Ingham  <jingham@apple.com>

    * ChangeLog - created.
    * RBNContext.h: Added m_arg_vec and accessors.
    * RNBContext.cpp (SetProcessID): New function.
    * RBNRemote.h: Added packet type to HandlePacket & HandleAsyncPacket
    * RNBRemote.cpp (HandlePacket, HandleAsyncPacket): Return type.
    (HandlePacket_A): Fix a few bugs.
    (HandlePacket_H): Return OK if target is not yet running.
    (HandlePacket_q): Return PID of 0 if target is not yet running.
    * testremotenub.cpp (RNBRunLoopGetArgsFromRemote): Implement.
    (RNBRunLoopLaunchInferior): Fetch arguments from context.
    (main) Store arguments in context, call RNBRunLoopGetArgsFromRemote
    if appropriate.
