Nick Coghlan d2e0938362 Issue #3781: Final cleanup of warnings.catch_warnings and its usage in the test suite. Closes issue w.r.t. 2.6 (R: Brett Cannon) 2008-09-11 12:11:06 +00:00
Brett Cannon 672237dc6c warnings.catch_warnings() now returns a list or None instead of the custom
WarningsRecorder object. This makes the API simpler to use as no special object
must be learned.

Closes issue 3781.

Brett Cannon 1eaf0742d8 Move test.test_support.catch_warning() to the warnings module, rename it
catch_warnings(), and clean up the API.

While expanding the test suite, a bug was found where a warning about the
'line' argument to showwarning() was not letting functions with '*args' go
without a warning.

Closes issue 3602.

Brett Cannon bfb997d6a5 Make test.test_support.catch_warning() take an argument specifying if any
triggered warnings should be captured. This allows the context manager to be
used to just prevent the internal state of the 'warnings' framework and thus
allow triggered warnings to be displayed.

Brett Cannon e974689038 Re-implement the 'warnings' module in C. This allows for usage of the
'warnings' code in places where it was previously not possible (e.g., the
parser). It could also potentially lead to a speed-up in interpreter start-up
if the C version of the code (_warnings) is imported over the use of the
Python version in key places.

Closes issue #1631171.

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.

Brett Cannon 8d2a90af2d Generalize test.test_support.test_stdout() with a base context manager so that
it is easy to capture stderr if desired.

Brett Cannon c6b5200931 Fix a minor typo in a docstring. 2008-02-25 05:33:33 +00:00
Neal Norwitz 6057b2e645 Create a db_home directory with a unique name so multiple users can
run the test simultaneously.  The simplest thing I found that worked
on both Windows and Unix was to use the PID.  It's unique so should be
sufficient.  This should prevent many of the spurious failures of
the automated tests since they run as different users.

Also cleanup the directory consistenly in the tearDown methods.

It would be nice if someone ensured that the directories are always
created with a consistent name.

Christian Heimes c5f05e45cf Patch #2167 from calvin: Remove unused imports 2008-02-23 17:40:11 +00:00
Neal Norwitz 880605aafd Let the O/S supply a port if none of the default ports can be used.
This should make the tests more robust at the expense of allowing
tests to be sloppier by not requiring them to cleanup after themselves.
(It will legitamitely help when running two test suites simultaneously
or if another process is already using one of the predefined ports.)

Also simplifies (slightLy) the exception handling elsewhere.

Brett Cannon 2ee4128e9b Remove test.test_support.guard_warnings_filter.
test.test_support.catch_warning is more full-featured and provides the same
functionality.

Since guard_warnings_filter was added in 2.6 there is no
backwards-compatibility issues.

Collin Winter fa9be8c289 Fix a bug in test.test_support.open_urlresource().
If the call to requires() doesn't precede the filesystem check, we get the following situation:
1. ./python Lib/test/regrtest.py test_foo # test needs urlfetch, not enabled, so skipped
2. ./python Lib/test/regrtest.py -u urlfetch test_foo # test runs
3. ./python Lib/test/regrtest.py test_foo # test runs (!)

By moving the call to requires() *before* the filesystem check, the fact that fetched files are cached on the local disk becomes an implementation detail, rather than a semantics-changing point of note.

Walter Dörwald e6dae6c655 Implement a contextmanager test.test_support.catch_warning that can

Brett Cannon 41d4e32353 Add test.test_support.transient_internet . Returns a context manager that
nests test.test_support.TransientResource context managers that capture
exceptions raised when the Internet connection is flaky.

Initially using in test_socket_ssl but should probably be expanded to cover any
test that should not raise the captured exceptions if the Internet connection
works.
2007-03-13 02:34:09 +00:00
Brett Cannon a30fcb4dae Introduce test.test_support.TransientResource. It's a context manager to
surround calls to resources that may or may not be available.  Specifying the
expected exception and attributes to be raised if the resource is not available
prevents overly broad catching of exceptions.

This is meant to help suppress spurious failures by raising
test.test_support.ResourceDenied if the exception matches.  It would probably
be good to go through the various network tests and surround the calls to catch
connection timeouts (as done with test_socket_ssl in this commit).

Armin Rigo 97ff04789d Concatenation on a long string breaks (SF #1526585). 2006-08-09 15:37:26 +00:00
Neal Norwitz b15ac3169d Add new utility function, reap_children(), to test_support. This should
be called at the end of each test that spawns children (perhaps it
should be called from regrtest instead?).  This will hopefully prevent
some of the unexplained failures in the buildbots (hppa and alpha)
during tests that spawn children.  The problems were not reproducible.
There were many zombies that remained at the end of several tests.
In the worst case, this shouldn't cause any more problems,
though it may not help either.  Time will tell.

Neal Norwitz 9602cc2aa4 Prevent spurious leaks when running regrtest.py -R. There may be more
issues that crop up from time to time, but this change seems to have been
pretty stable (no spurious warnings) for about a week.

Other modules which use threads may require similar use of
threading_setup/threading_cleanup from test_support.
