A collection of utility functions and classes, used internally by Trial.
This code is for Trial's internal use. Do NOT use this code if you are writing
tests. It is subject to change at the Trial maintainer's whim. There is
nothing here in this module for you to use unless you are maintaining Trial.
Any non-Trial Twisted code that uses this module will be shot.

Coerce a Failure to an _exc_info, if err is a Failure.
@param err: Either a tuple such as returned by L{sys.exc_info} or a
L{Failure} object.
@return: A tuple like the one returned by L{sys.exc_info}. e.g.
C{exception_type, exception_object, traceback_object}.

Sets up the .suppress tuple properly, pass options to this method as you
would the stdlib warnings.filterwarnings()
So, to use this with a .suppress magic attribute you would do the
following:
>>> from twisted.trial import unittest, util
>>> import warnings
>>>
>>> class TestFoo(unittest.TestCase):
... def testFooBar(self):
... warnings.warn("i am deprecated", DeprecationWarning)
... testFooBar.suppress = [util.suppress(message='i am deprecated')]
...
>>>
Note that as with the todo and timeout attributes: the module level
attribute acts as a default for the class attribute which acts as a default
for the method attribute. The suppress attribute can be overridden at any
level by specifying C{.suppress = []}

Find an unused directory named similarly to C{base}.
Once a directory is found, it will be locked and a marker dropped into it
to identify it as a trial temporary directory.
@param base: A template path for the discovery process. If this path
exactly cannot be used, a path which varies only in a suffix of the
basename will be used instead.
@type base: L{FilePath}
@return: A two-tuple. The first element is a L{FilePath} representing the
directory which was found and created. The second element is a locked
L{FilesystemLock}. Another
call to C{_unusedTestDirectory} will not be able to reused the
same name until the lock is released, either explicitly or by this
process exiting.

Produce a string containing each thing in C{things},
separated by a C{delimiter}, with the last couple being separated
by C{finalDelimiter}

(typically 'and' or 'or')

not including the last two. Should typically include a trailing space.
