tearDownClass is not called if setUpClass throws an exception, in our case
this means that LiveServerTestCase leaks LiveServerThread sockets if the
test happens to be skipped later on, and AdminSeleniumWebDriverTestCase
doesn't close it's already open browser window. To prevent this leakage
we catch errors where needed and manually call _tearDownClassInternal.
_tearDownClassInternal should be written as defensively as possible since
it is not allowed to make any assumptions on how far setUpClass got.
This patch should fix the sporadic "Address already in use"-errors on jenkins
and also the "This code isn't under transaction management"-error for sqlite
(also just on jenkins).
After discussion with koniiiik, jezdez, kmtracey, tos9, lifeless, nedbat and
voidspace it was decided that this is the safest approach (thanks to everyone
for their comments and help). Manually calling tearDownClass was shut down
cause we don't know how our users override our classes.
This is a private and very specialized API on purpose and should not be used
without a strong reason!
This patch partially reverts the earlier attempts to fix those issues,
namely:
2fa0dd73b1 and
3c5775d36f
Final note: If this patch breaks in a later version of Django, please be
very careful on how you fix it, you might not see test failures locally.
That said, this patch hopefully doesn't produce even more failures.
If setUpClass throws an exception (in this case "Address already in use" if the
super call can't find any open port to bind too) tearDownClass is not called.
This results in open browser windows from the webdriver, hence we only construct
it once we are sure there is no code afterwards which could error out.
We want to be able to use it for instance for discovering `tasks.py` modules
inside the INSTALLED_APPS.
This commit therefore moves the logic to `autodiscover_modules` method in
django.utils.module_loading.
The Admin widget, which can be used to filter multiple selects
can sometimes be too narrow and hide information such as
user permissions. This commit adds tooltips to the select
options so that a user can hover over and see the hidden text.
AdminSite now has overridable site_header, site_title and index_title attributes. Changed
each admin view to pass these to the context (in a new AdminSite.each_context() method).
The intent here is to make it easier to override these things in the common case, instead of
having to override a template, which is a bigger burden.
The view tried to display links to a ModelAdmin's change_view, which
resulted in NoReverseMatches if get_urls was overridden to remove the
corresponding url.
The default delete action resulted in a NoReverseMatch if it were to
list any Model with a ModelAdmin with `get_urls` overridden to remove
the change url. Catching the error and not displaying the link in that
case, as was already done for models with no registered admins.
Thanks Keryn Knight for the report.
