Hi Chris, Pavel,
I've got a problem launching the hexagon simulator from lldb. It's launched
the same way that debugserver/lldb-server is launched, with reverse connect
on a TCP socket. The user can modify the simulator command line (using
target.run-args), and can easily give a set of options that the simulator
can't handle. In this case the simulator quits before connecting to lldb,
and lldb will wait forever for the connection, since TCPSocket::Accept has
no timeout.
Currently I have a select call before the accept, to make sure there is
activity on the socket. This doesn't feel right with the new changes using
MainLoop, so I wanted to see what the list thinks. I believe it will happen
any time that debugserver/lldb-server quits or crashes before connecting.
That should be easy to test.
This is what I use, right before the call to accept_loop.Run in
TCPSocket::Accept:
NativeSocket accept_socket = -1;
fd_set readset;
FD_ZERO(&readset);
for (auto socket : m_listen_sockets) {
auto fd = socket.first;
FD_SET(fd, &readset);
if (fd > accept_socket)
accept_socket = fd;
}
struct timeval timeout = {10, 0};
int result = ::select(accept_socket + 1, &readset, NULL, NULL,
&timeout);
if (result == 0) {
printf("error: timeout waiting for remote server to connect!\n");
error.SetErrorString("timeout waiting for remote server to connect");
return error;
} else if (result < 0) {
printf("error: remote server does not exist!\n");
SetLastError(error);
return error;
}
Any thoughts this issue?
