Defect #34634
closed
Deletion of project wiki leaves the project wiki inaccessible (404) until module reactivation
0%
Description
This issue is inspired by a thread in the forum ()
An user delete all wiki pages including the root page. Then he could not see the root page and could not create wiki pages any more.
The solution was to disable Wiki module and then enable it again. Then the root wiki page appeared again (may be it has been recreated on enabling wiki module).
So I think that it should be harder to delete the root wiki page or make it not erasable.
However, if it remains erasable, Wiki module should be made inactive when this page is deleted.

Thanks for opening this issue. I've been reading along and it already got me curious, so I already had a look at the source. I can confirm the reported behavior (at least partially, as far as I've tested). Along the way I found several other issues too.
I'm working on providing a patch.

I confirm this is a problem when a whole project wiki is deleted. I don't see this being a problem when deleting single wiki pages.
Ivan Khrustalev: can you too confirm this (also with the OP of )?
I have posted a patch that fixes this case as part of #34643 (file: 4. Disable the wiki module after deletion of a project wiki.). It should be applicable on its own.

I've extracted the patch proposed by Mischa The Evil in #34643:
- 4. Disable the wiki module after deletion of a project wiki.
By adding a (private)after_destroy:disable_wiki_modulecallback that disables the wiki module after deletion of a project wiki, we prevent the need to explicitly have to disable the wiki module first, before (re-)enabling the module would eventually create a new project wiki and reset thestart_page.
I still think that it's a good ideea to inform the user that deleting the wiki root page will automatically disable the module.

Sure. However, now that I have had a second look at this, I think that disabling the module after the deletion is a bit of an ugly workaround. A better solution would be to implement something like a 'no data' message when a project wiki is missing and add a way for users with the required permission(s) to reinstate a new wiki by just letting them add new pages from the front-end while creating a new project wiki in the background automatically if one is not yet available. That would also take away the need for an additional notification message. What do you think?
Btw: I think you got it but to be certain, when you wrote ...deleting the wiki root page... -> it's actually about deleting the project's wiki itself. I've written about this is more detail in .

What do you think if we create a new empty Wiki after deletion?

FWIW: I think that'll work too. Though, for clarity it might be better to change the name of the proposed class method Wiki.create_default_page to something more generic like just Wiki.create_default since we're actually creating a Wiki object, not an object associated with wiki pages (i.e. WikiPage).

Thanks for your feedback, Mischa. I will try to catch this in 5.1.0.

I've committed the patch that reinitialise an empty wiki page after the project wiki is deleted. I don't see really necessary to have an extra message for this.

Thanks! And I agree with you that an additional message would be unnecessary.
