[patch] User deletion ordering breaks 'deleted' notification for SessionStore

Reported by: nathaniel@… Owned by: Steffen Hoffmann
Priority: normal Component: AccountManagerPlugin
Severity: normal Keywords: user delete notification
Cc: Trac Release: 0.12


If you use the DB storage backend for users, the deleted event never fires. This is due to the fact that the ordering is wrong. The attached patch fixes this issue.

Keywords: user delete notification added

Thank you for informing us about this issue. Notification via TracAnnouncer is currently broken, so I could hardly notice this myself.

From first glance I heartily recommend to only do what you declare. Removing comments shouldn’t be your business, at least unless you've proven before, that they are wrong.

I'll have a closer look at this later, within the next few days.

Ok, the comments are gone in the current code anyway. Adapted the patch, and it looks good.

(In [11250]) AccountManagerPlugin: Change sequence of actions when deleting a user, refs #8685.

Nathaniel McCallum noticed, that with SessionStore db storage backend the 'user deleted' event never fires due to wrong ordering of actions. The call to store.delete_user is more elegant - pythonic - now, but a bit more subtle to me too.

Thanks for spotting this and even more for providing a fix as well.

(In [11251]) AccountManagerPlugin: Split retrieval and call to delete_user method, refs #8685.

I felt concerned enough about the change to the delete method call in [11250] to research it a bit more and found i.e.:

Afterwards I decided to use an alternative, more inflated pattern, that calls the method retrieved by getattr only if it exists and appears to be callable.

Rationale: Dealing with multiple, even concurrent AuthStores tends to become complicated, so avoiding confusion about AttributeError exceptions raised by getattr with similar exceptions raised inside the called method itself seems like a reasonable precaution.

Availability of that code as stable release closes #874, #3459, #4677, #5295, #5691, #6616, #7577, #8076, #8685, #8770, #8791, #8990, #9052, #9079, #9090, #9139, #9246, #9252, #9547, #9618, #9676, #9843, #9852, #9940, #10023, #10028, #10123, #10142, #10204, #10276, #10397, #10412, #10594, #10625 and #10644.

Some more issues have been worked-on, yet without confirmed resolution, refs #5464 (for JiraToTracIntegration), #8927 and #10134.

And finally there are some issues and enhancement requests showing progress, but known to require more work to resolve them satisfactorily, refs #843, #1600, #5964, #8217, #8933.

Thanks to all contributors and followers, that enabled and encouraged a good portion of this development work.
