After upgrading to 8.1.2 from 7.84.0, I found that sockets were being
closed without calling the fclosesocket callback if a request was
cancelled after the associated socket was created, but before the socket
was connected. This lead to an imbalance of fopensocket & fclosesocket
callbacks, causing problems with a custom event loop integration using
the multi-API.
This was caused by cf_socket_close() calling sclose() directly instead
of calling socket_close() if the socket was not active. For regular TCP
client connections, the socket is activated by cf_socket_active(), which
is only called when the socket completes the connect.
As far as I can tell, this issue has existed since 7.88.0. That is,
since the code in question was introduced by:
