Description

Read-only mode is a setting an admin can enable to prevent writes to
the database. This can be used when the site is under maintenence or
being upgraded. This commit disables most UI features which would
normally affect Review Board, but under read-only mode, does not.
Disabling some features such as login and redirection when attempting
to view a read-only restricted page is contained in the next commit.

This commit contains changes to the datagrid so changes to it does not
change profile settings, navbar (hide My Account and New Review Request
buttons), ETag, ReviewRequestEditor(including actions, comments, and
the editor itself),

Other changes include adding read-only mode setting to the context
processor and adding a utility file containing the logic to determine
whether a user is in read-only mode or not.

Testing Done


Check that caching of read-only mode is done correctly by changing

modes and refreshing pages
Check that profile doesn't save in datagrid when in read-only mode by

ensuring code doesn't reach the save method
Check that the review request actions available are appropriately

changed when in read-only mode
Check that comments can't be added or replied to in read-only mode
Check that review requests can not be modified in read-only mode
Check that modifying review requests (such as bugs or branch) when in

read-only mode while the site in browser is still old displayed an

appropriate error message
Check that modifying anything to the webapi doesn't send a request at

all when in read-only mode
Check that trying to add a comment through clicking on a line in diff

displays appropriate warning about read-only mode
Check that clicking on the Star does nothing in read-only mode
Check that the above does not occur for admins

Perhaps I can move the not ... to be the first term of this expression, but these have to be aligned with the inner-most open parenthesis for the value/subexpression. So here, the not is in-line with the first parenthesis right after return.

szhang March 13, 2017, 4:02 p.m.

Ah! My mistake. Too many opening/closing brackets confuse me. Sorry for the bad review.

I'd say you don't need to move the not ... just to make the indentation a little more clear to people like me. :)

Where does disable_save come from? Is there a change for Djblets that isn't up for review?

It's better to have options be positive rather than negative. For instance, "enable_save" vs. "disable_save." I'm not sure I love either, though.

There are lots of places where a Profile gets modified, and I don't think we should special-case every single place in existence. Instead, I'd override Profile.save and have it not save if is_site_read_only_for returns True. That way, the DataGrid can try saving all it wants, but it won't matter.

khp March 14, 2017, 4:45 a.m.

The change to djblets didn't show up here, but I agree that overriding Profile would be better. I thought it was a django class so it would be less work this way, but I found it in rb models. I changed the Profile.save() and tested that the override worked by ensuring the code reaches the conditional which returns early with a print statement.

Moved read_only.py and webapi/base.py changes to previous diff, review #8657. Since the review is based on the old 8657 still, it will not show read_only.py and the webapi.py changes on this diff, but once it is applied on 8657 it should show.

Does is_site_read_only_for correctly handle user=None ?

khp April 6, 2017, 3:49 a.m.

Can user ever not be in context? Especially since this is for rendering a reply, it seems like a place where a user would have to have been determined for the context. Would it be safe to remove the default value of None on context.get('user', None)?

I can also handle None in is_site_read_only_for just in case it can happen, but I figured user will always be something by the time it gets used by is_site_read_only_for

brennie April 6, 2017, 12:54 p.m.

Since context is a dict, context.get(key) has a default return of None, so you can get rid of that. However, you should just do user = context['user'].

Do we want this to be user-visible? Or is this only for debugging?

khp April 6, 2017, 3:49 a.m.

I intended this to be a user-visible message as Christian in a previous review requested for some logging here to help with diagnosing stuff.

Description:

~		Read-only mode is a setting an admin can enable to prevent writes to the database. This can be used when the site is under maintenence or being upgraded. This commit disables most UI features which would normally affect Review Board, but under read-only mode, does not. Disabling some features such as login and redirection when attempting to view a read-only restricted page is contained in the next commit.

Testing Done:

~		Check that caching of read-only mode is done correctly by changing modes and refreshing pages
~		Check that profile doesn't save in datagrid when in read-only mode by ensuring code doesn't reach the save method
~		Check that the review request actions available are appropriately changed when in read-only mode
~		Check that comments can't be added or replied to in read-only mode
~		Check that review requests can not be modified in read-only mode
~		Check that modifying review requests (such as bugs or branch) when in read-only mode while the site in browser is still old displayed an appropriate error message
~		Check that modifying anything to the webapi doesn't send a request at all when in read-only mode
~		Check that trying to add a comment through clicking on a line in diff displays appropriate warning about read-only mode
~		Check that clicking on the Star does nothing in read-only mode
~		Check that the above does not occur for admins

This needs Args.

It should also start off by saying the main thing that it does: "Saves the profile to the database."

Then, in the description, it should say that if the site is in read-only mode, the profile will not be saved.

Parameters should align.

This should also use format strings:

console.log('%s request not sent ...',
            options.type);

I'd also maybe use console.error instead.

Instead of this, why not just

readOnly: {% is_read_only|yesno:'true,false' %},

That way the information is always available.
