- Issue #2550: The approach used by client/server code for obtaining ports to listen on in network-oriented tests has been refined in an effort to facilitate running multiple instances of the entire regression test suite in parallel without issue. test_support.bind_port() has been fixed such that it will always return a unique port -- which wasn't always the case with the previous implementation, especially if socket options had been set that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The new implementation of bind_port() will actually raise an exception if it is passed an AF_INET/SOCK_STREAM socket with either the SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on the socket it's been passed. This currently only applies to Windows. This option prevents any other sockets from binding to the host/port we've bound to, thus removing the possibility of the 'non-deterministic' behaviour, as Microsoft puts it, that occurs when a second SOCK_STREAM socket binds and accepts to a host/port that's already been bound by another socket. The optional preferred port parameter to bind_port() has been removed. Under no circumstances should tests be hard coding ports! test_support.find_unused_port() has also been introduced, which will pass a temporary socket object to bind_port() in order to obtain an unused port. The temporary socket object is then closed and deleted, and the port is returned. This method should only be used for obtaining an unused port in order to pass to an external program (i.e. the -accept [port] argument to openssl's s_server mode) or as a parameter to a server-oriented class that doesn't give you direct access to the underlying socket used. Finally, test_support.HOST has been introduced, which should be used for the host argument of any relevant socket calls (i.e. bind and connect). The following tests were updated to following the new conventions: test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib, test_poplib, test_ftplib, test_telnetlib, test_socketserver, test_asynchat and test_socket_ssl. It is now possible for multiple instances of the regression test suite to run in parallel without issue.

The ThreadableTest class makes it easy to create a threaded
client/server pair from an existing unit test. To create a
new threaded class from an existing unit test, use multiple
inheritance:
class NewClass (OldClass, ThreadableTest):
pass
This class defines two new fixture functions with obvious
purposes for overriding:
clientSetUp ()
clientTearDown ()
Any new test functions within the class must then define
tests in pairs, where the test name is preceeded with a
'_' to indicate the client portion of the test. Ex:
def testFoo(self):
# Server portion
def _testFoo(self):
# Client portion
Any exceptions raised by the clients during their tests
are caught and transferred to the main thread to alert
the testing framework.
Note, the server setup function cannot call any blocking
functions that rely on the client thread during setup,
unless serverExplicitReady() is called just before
the blocking call (such as in setting up a client/server

The new implementation of bind_port() will actually raise an exception if it is passed an AF_INET/SOCK_STREAM socket with either the SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on the socket it's been passed. This currently only applies to Windows. This option prevents any other sockets from binding to the host/port we've bound to, thus removing the possibility of the 'non-deterministic' behaviour, as Microsoft puts it, that occurs when a second SOCK_STREAM socket binds and accepts to a host/port that's already been bound by another socket. The optional preferred port parameter to bind_port() has been removed. Under no circumstances should tests be hard coding ports! test_support.find_unused_port() has also been introduced, which will pass a temporary socket object to bind_port() in order to obtain an unused port. The temporary socket object is then closed and deleted, and the port is returned. This method should only be used for obtaining an unused port in order to pass to an external program (i.e. the -accept [port] argument to openssl's s_server mode) or as a parameter to a server-oriented class that doesn't give you direct access to the underlying socket used. Finally, test_support.HOST has been introduced, which should be used for the host argument of any relevant socket calls (i.e. bind and connect). The following tests were updated to following the new conventions: test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib, test_poplib, test_ftplib, test_telnetlib, test_socketserver, test_asynchat and test_socket_ssl.

- Issue #2550: The approach used by client/server code for obtaining ports to listen on in network-oriented tests has been refined in an effort to facilitate running multiple instances of the entire regression test suite in parallel without issue. test_support.bind_port() has been fixed such that it will always return a unique port -- which wasn't always the case with the previous implementation, especially if socket options had been set that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The new implementation of bind_port() will actually raise an exception if it is passed an AF_INET/SOCK_STREAM socket with either the SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on the socket it's been passed. This currently only applies to Windows. This option prevents any other sockets from binding to the host/port we've bound to, thus removing the possibility of the 'non-deterministic' behaviour, as Microsoft puts it, that occurs when a second SOCK_STREAM socket binds and accepts to a host/port that's already been bound by another socket. The optional preferred port parameter to bind_port() has been removed. Under no circumstances should tests be hard coding ports! test_support.find_unused_port() has also been introduced, which will pass a temporary socket object to bind_port() in order to obtain an unused port. The temporary socket object is then closed and deleted, and the port is returned. This method should only be used for obtaining an unused port in order to pass to an external program (i.e. the -accept [port] argument to openssl's s_server mode) or as a parameter to a server-oriented class that doesn't give you direct access to the underlying socket used. Finally, test_support.HOST has been introduced, which should be used for the host argument of any relevant socket calls (i.e. bind and connect). The following tests were updated to following the new conventions: test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib, test_poplib, test_ftplib, test_telnetlib, test_socketserver, test_asynchat and test_socket_ssl. It is now possible for multiple instances of the regression test suite to run in parallel without issue.

The new implementation of bind_port() will actually raise an exception if it is passed an AF_INET/SOCK_STREAM socket with either the SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on the socket it's been passed. This currently only applies to Windows. This option prevents any other sockets from binding to the host/port we've bound to, thus removing the possibility of the 'non-deterministic' behaviour, as Microsoft puts it, that occurs when a second SOCK_STREAM socket binds and accepts to a host/port that's already been bound by another socket. The optional preferred port parameter to bind_port() has been removed. Under no circumstances should tests be hard coding ports! test_support.find_unused_port() has also been introduced, which will pass a temporary socket object to bind_port() in order to obtain an unused port. The temporary socket object is then closed and deleted, and the port is returned. This method should only be used for obtaining an unused port in order to pass to an external program (i.e. the -accept [port] argument to openssl's s_server mode) or as a parameter to a server-oriented class that doesn't give you direct access to the underlying socket used. Finally, test_support.HOST has been introduced, which should be used for the host argument of any relevant socket calls (i.e. bind and connect). The following tests were updated to following the new conventions: test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib, test_poplib, test_ftplib, test_telnetlib, test_socketserver, test_asynchat and test_socket_ssl.
