ifdefs. 1429 1430 2008-01-22 Jason Molenda (jmolenda (a] apple.com) 1431 1432 * RNBRemote.cpp (RNBRemote::CreatePacketTable): Recognize 1433 QStartNoAckMode as an unsupported remote protocol request. 1434 * RNBRemote.h: Add start_noack_mode enum entry. 1435 1436 2008-01-22 Greg Clayton (gclayton (a] apple.com) 1437 1438 * DNBLog.h: Removed C++ namespace for DNBLog (changed all DNBLog:: 1439 to DNBLog) so C99 var arg macros can be used to completely disable 1440 all logging and any functions that may be called when making the 1441 variable arguments. 1442 * DNBLog.cpp: Ditto. 1443 * DNB.cpp: Ditto. 1444 * DNBBreakpoint.cpp: Ditto. 1445 * DNBError.cpp: Ditto. 1446 * MacOSX/MachDYLD.cpp: Ditto. 1447 * MacOSX/MachException.cpp: Ditto. 1448 * MacOSX/MachProcess.cpp: Ditto. 1449 *

2008-01-21 Jason Molenda (jmolenda (a] apple.com) 1462 1463 * test-remotenub.cpp: Add NO_SPRINGBOARD for turning off SpringBoard 1464 dependency ala NO_ACKS. 1465 1466 2008-01-18 Jason Molenda (jmolenda (a] apple.com) 1467 1468 * RNBSocket.h (RNBSocket::RNBSocket): Take either a port # or 1469 an already-opened socket, with a boolean to indicate which it is. 1470 * RNBRemote.cpp (RNBRemote::RNBRemote): Ditto. 1471 * RNBRemote.h: Prototype update. 1472 * test-remotenub.cpp: Include lockdown.h. Take --lockdown command 1473 line arg, get the socket from liblockdown.dylib instead of opening 1474 our own socket if it is specified. --lockdown indicates that 1475 the program name/args will be provided via remote protocol instead 1476 of on the command line. 1477 1478 2008-01-17 Jason Molenda (jmolenda (a] apple.com) 1479 1480 * RNBRemote.cpp: Add NO_ACKS #ifdefs around code that computes 1481 the checksums and sends/expects the gdb remote protocol ACK packets. 1482 If NO_ACKS is defined, debugserver will not send or expect acks. 1483 * test-remotenub.cpp (main): Print a different version string 1484 if NO_ACKS is defined. 1485 1486 2008-01-16 Greg Clayton (gclayton (a] apple.com) 1487 1488 * PThreadEvent.cpp: Added this pointer to all logging calls. 1489 1490 2008-01-16 Greg Clayton (gclayton (a] apple.com) 1491 1492 * RNBSocket.cpp (RNBSocket::Connect()): Use TCP so we can try the 1493 TCP_NODELAY socket option. 1494 (RNBSocket::SetSocketOption()): New function. 1495 * RNBSocket.h (RNBSocket::SetSocketOption()): New class function. 1496 1497 2008-01-14 Jason Molenda (jmolenda (a] apple.com) 1498 1499 * RNBRemote.cpp (RNBRemote::HandlePacket_last_signal): When printing 1500 registers, skip over gdb regs which don't map to DNB regs. 1501 1502 2008-01-14 Jim Ingham <jingham (a] apple.com> 1503 1504 * ChangeLog - created. 1505 * RBNContext.h: Added m_arg_vec and accessors. 1506 * RNBContext.cpp (SetProcessID): New function. 1507 * RBNRemote.h: Added packet type to HandlePacket & HandleAsyncPacket 1508 * RNBRemote.cpp (HandlePacket, HandleAsyncPacket): Return type. 1509 (HandlePacket_A): Fix a few bugs. 1510 (HandlePacket_H): Return OK if target is not yet running. 1511 (HandlePacket_q): Return PID of 0 if target is not yet running. 1512 * testremotenub.cpp (RNBRunLoopGetArgsFromRemote): Implement. 1513 (RNBRunLoopLaunchInferior): Fetch arguments from context. 1514 (main) Store arguments in context, call RNBRunLoopGetArgsFromRemote 1515 if appropriate. 1516
