Re: [Sqlrelay-discussion] Forked listener removes unix socket file (patch available)

[David M. <dav...@fi...>]

Ahhh, I see the problem...

I think a cleaner solution might be to remove the setting of pidfile to 
NULL after the fork() and just wrap the removal of the pid and unixport 
files with an "if (!isforkedchild) {" in the destructor.  Then the 
semset, idmemory and cmdl objects would still be freed.

What do you think?
