When the test client detects a redirect to a URL seen in the
currently followed chain it will now raise a RedirectCycleError
instead of just returning the first repeated response.
It will also complain when a single chain of redirects is longer
than 20, as this often means a redirect loop with varying URLs,
and even if it's not actually one, such long chains are likely
to be treated as loops by browsers.
Thanks Preston Timmons, Berker Peksag, and Tim Graham for reviews.
This is useful for debugging side effects affecting tests that
are usually executed before a given test. Full suite and pair
tests sort cases more or less deterministically, thus some test
cross-dependencies are easier to reveal by reversing the order.
Thanks Preston Timmons for the review.
Since RequestContext doesn't know its Engine until it's passed to
Template.render() -- and cannot without breaking a widely used public
API -- an elaborate hack is required to apply context processors.
Passed the engine instance to loaders. This is a prerequisite for
looking up configuration on the engine instance instead of global
settings.
This is backwards incompatible for custom template loaders that override
__init__. However the documentation doesn't talk about __init__ and the
way to pass arguments to custom template loaders isn't specified. I'm
considering it a private API.
This change has the nice side effect of removing code that ran at import
time and depended on the app registry at module level -- a notorious
cause of AppRegistryNotReady exceptions.
Reformatted the code of base.Loader according to modern standards.
Turned the test template loader into a regular locmem.Loader -- but
didn't document it.
Added a normal deprecation path for BaseLoader which is a public API.
Added an accelerated deprecation path for TestTemplateLoader which is
a private API.
That commit contained a mistake that resulted in the use_cached_loader
option of override_with_test_loader being ignored. As a consequence some
configurations weren't exercised any more by the test suite.
Keeping backwards compatibility with test_runner.option_list is
tricky and would imply transforming an optparse.Option to an
argparse.Action. I choose to introduce a backwards incompatible
change because it only affects testing, not runtime behavior.
