Antoine Pitrou 643e85df48 Try to fix transient refleaks in test_asynchat. 2009-10-30 17:55:21 +00:00
R. David Murray 59beec326a Add import_function method to test.test_support, and modify a number of
tests that expect to be skipped if imports fail or functions don't
exist to use import_function and import_module.  The ultimate goal is
to change regrtest to not skip automatically on ImportError.  Checking
in now to make sure the buldbots don't show any errors on platforms
I can't direct test on.

Trent Nelson e41b0061dd - 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.

Neal Norwitz 6e070814b2 Eliminate the sleeps that assume the server will start in .5 seconds.
This should make the test less flaky.  It also speeds up the test
by about 75% on my box (20+ seconds -> ~4 seconds).

Facundo Batista 4950442fb7 When running asynchat tests on OS X (darwin), the test client now
overrides asyncore.dispatcher.handle_expt to do nothing, since
select.poll gives a POLLHUP error at the completion of these tests.
Added timeout & count arguments to several asyncore.loop calls to
avoid the possibility of a test hanging up a build. [GSoC - Alan

Facundo Batista ec62423be4 Added tests for asynchat classes simple_producer & fifo, and the
find_prefix_at_end function. Check behavior of a string given as a
producer.  Added tests for behavior of asynchat.async_chat when given
int, long, and None terminator arguments. Added usepoll attribute to
TestAsynchat to allow running the asynchat tests with poll support
chosen whether it's available or not (improves coverage of asyncore
code). [GSoC - Alan McIntyre]

Neal Norwitz 62bc8aadd4 Don't fail if another process is listening on our port. 2006-06-13 04:08:53 +00:00
Michael W. Hudson 7390942aa1 test_asynchat is no longer expected to produce output.
also, wait for threads to finish before proceeding.

Guido van Rossum f3ee46b82a Set the SO_REUSEADDR socket option in the server thread -- this seems
needed on some platforms (e.g. Solaris 8) when the test is run twice
in quick succession.

Guido van Rossum 9df3eabd6e Add "import thread" at the top of the module; this prevents us from
failing later when Python is compiled without threading but a failing
'threading' module can be imported due to an earlier (caught) attempt.

Guido van Rossum dca060c55c After testing the test on Unix, several improvements:
- Use push() instead of send(), and make these calls in main().

- Sleep a second to give the server thread time to initialize itself.

Guido van Rossum 66172520ee Add test for asynchat. This also tests asyncore. 2001-04-06 16:32:22 +00:00
