spindle_logd does not delete heap allocations #171

Description

@SamHerts

Bug:

MsgReader allocates a new connection onto the heap but delete is never called on the connection

Allocation:

Connection *con = new Connection();

Connection cleanup

Only removes the connection from the map:

for (std::map<int, Connection *>::iterator i = conns.begin(); i != conns.end(); i++) {
if (i->second->shutdown) {
conns.erase(i);

Only closes the file descriptor and clears the map:

~MsgReader()
{
for (std::map<int, Connection *>::iterator i = conns.begin(); i != conns.end(); i++) {
int fd = i->first;
close(fd);
}
conns.clear();

Fix:

Two options:

 for (std::map<int, Connection *>::iterator i = conns.begin(); i != conns.end(); i++) { 
    if (i->second->shutdown) { 
       delete i->second;
       conns.erase(i);
 ~MsgReader() 
 { 
    for (std::map<int, Connection *>::iterator i = conns.begin(); i != conns.end(); i++) { 
       int fd = i->first; 
       close(fd);
       delete i->second;
    } 
    conns.clear();

Or swap to an std::unique_ptr:

std::map<int, std::unique_ptr<Connection>> conns;
...
Connection *con = std::make_unique<Connection>();
