[mediawiki/extensions/CentralAuth@master] Remove partial blocks from Special:CentralAuth

https://gerrit.wikimedia.org/r/501452

I think it'd be useful to display if a person is partially blocked on CentralAuth. Stewards and other people look at CentralAuth to see the blocking status of accounts, etc. If a candidate for permission X or other type of global access is partially blocked that information is very much relevant for us. I do not support removing the existance of partial blocks via CentralAuth. Make it properly display that the block is partial instead. Thanks.

Hi, I am afraid I do not understand the reasoning.

In your screenshot the account is fully (and not partially [whatever that means]) blocked on testwiki. Of course, that local block should be shown in a summary of the global account status which gives information on every single wiki. That's the reason of a local block while there is another field called “Locked: yes” which indicates that the account is globally locked.

Please help me understand what you mean with “partial” block. Thank you! :-)

@MarcoAurelio @DerHexer Let me try to answer as to why the original plan was to remove partial blocks from Special:CentralAuth and also reassure you that your feedback is essential for having the block feature work well for all necessary workflows that use it. So thank you for commenting.

Partial block was introduced primarily to address low level user misconduct that does not require a user to be blocked from the entire local wiki and certainly not globally blocked. This type of low level misconduct up to now was addressed on many wikis with warnings and instructions to users to stay away from certain pages or parts of a wiki. A longstanding request by admins was for changes to the block feature so a user could be blocked from pages or namespaces. A tech way to enforce user conduct sanctions. So, from the start the idea was to distinguish partial block from sitewide blocks, and lower the stigma associated with them. For this reason, partial block was not going to be indicated on CentralAuth.

Special:Block will be used much more often for sitewide blocks to address much more serious types of abuse. It is important to not disrupt workflows used by stewards, global admins, and local admins. So, we need to understand if having a partial block noted in CentralAuth is essential to workflows. If it is, then we can reconsider.

As far as I can see, almost everyone who took part in the discussion (about 10 participants [or more] excluding me) has said they want to see "partial" block information in the CA workflow. I think individuals can say what they think if they are inclined to do so.

@SPoore Thanks for clarifications. Now I understood what you meant with partial blocks. However, I still think that we should be transparent about that in general while functionaries should definitely see that at any time.

I agree with @MarcoAurelio, @DerHexer and @revi.

@MarcoAurelio @DerHexer @revi @Trijnstel It sounds like there is consensus to show partial block information on the CentralAuth page. We could do this similar to how it is displayed on Special:BlockList (5th column):

Does that sound good to everyone?

Looks good to me, I'll bring this to internal discussion.

I think we can manage with that, since we can easily look over which NS has that name (or ask people who know that language).

For example when someone is applying for Global Sysop, information that they are 'partial'ly blocked on wiki X is something we can ask candidates for clarification, or for other case we are investigating, we usually have someone who is familiar with the language to tell us what is the correct translation for the localized stuff.

Thank you. Sounds good.

[mediawiki/extensions/CentralAuth@master] Add blocking details for partial blocks to Special:CentralAuth.

https://gerrit.wikimedia.org/r/518087

@Niharika @dbarratt I have a question about how to display the list when there are a mix of local and global namespaces in the block.

With the current patch, a partial block displays something like this:

Global namespaces blocked	Local namespaces blocked

If there are a mixture of global and local namespaces, we could use either of these two options (the current patch uses the one on the left):

With "... and"	Without "... and"

My preference is for not using "... and". That way the translation messages are simpler, and the list is visually consistent with the list of local pages ("Foo" and "Bar" here), which doesn't add a preface to the final item.

@Tchanders I agree with not using ...and. It looks much cleaner and consistent without it while conveying the same information. Was it a conscious design decision to add it initially?

@Niharika Not that I'm aware of, it just came up in code review because of the messages
