  "message": "[lldb] Handle SIGINT via the MainLoop signal thread (on POSIX) (#196687)\n\nThe driver\u0027s async SIGINT handler called\nSBDebugger::DispatchInputInterrupt directly. That is not\nasync-signal-safe and can lead to a crash.\n\nRegister SIGINT with the existing signal-thread MainLoop instead so\nDispatchInputInterrupt runs in normal thread context. The Windows path\nis unchanged and keeps the legacy async handler.\n\nWhile DispatchInputInterrupt runs, the callback temporarily installs\nSIG_DFL so a second Ctrl-C still hard-terminates the process, preserving\nthe escape hatch users rely on when the debugger is unresponsive.\n\nMoving SIGINT off the main thread means a Ctrl-C no longer interrupts\nblocking syscalls there (e.g. a Python REPL waiting on input or\nsleeping), so Python never observes the queued interrupt and\nKeyboardInterrupt is not raised. To restore that behavior, after\ndispatching the interrupt the callback re-raises SIGINT on the main\nthread via pthread_kill; the resulting EINTR lets Python pick up the\npending interrupt. A skip flag suppresses the re-entry that this\nself-send produces. Because the callback only ever runs on the signal\nthread, the flag and the captured main-thread id live in the lambda\u0027s\ncaptures and need no synchronization.\n\nrdar://158218595",
