This change both speeds up specs (less strings to allocate) and helps catch
cases where methods in Discourse are mutating inputs.
Overall we will be migrating everything to use #frozen_string_literal: true
it will take a while, but this is the first and safest move in this direction
We had quite a few cases in core where inputs are being mutated as a side
effect of calling a method.
This handles all the cases where specs caught this.
Mutating inputs makes code harder to reason about. Eg:
```
frog = "frog"
jump(frog)
puts frog
"fly" # ?????
```
This commit is part of a followup commit that adds # frozen_string_literal
to all our specs.
If a tag group is set to only be visible to staff, and is restricted
to a category that is visible by everyone, the tags in the group were
being shown on the /tags page. They weren't visible anywhere else.
This commit fixes it so they don't show on the /tags page.
This test failed IF this category id number 3 was fabricated to start with
at the top of the test.
This is very likely if the test is run on a blank DB
Previous behaviour was to silently remove tags that
belonged to a group with a parent tag that was missing.
The "required parent tag" feature is meant to guide people
to use the correct tags and show scoped results in the tag
input field, and to help create topic lists of related
tags. It isn't meant to be a strict requirement in the
composer that should trigger errors or restrictions.
This is for backwards compatibility purposes. Even if `Upload#url` has a
format that we don't recognize, we should still return the upload object
as long as the upload record is present.
This test of `prevent_anons_from_downloading_files` was testing an image instead of an attachment and it was testing the wrong upload URL. I fixed the test, but with `config.public_file_server.enabled = true` on the test environment, this will always fail, as preventing anonymous file downloads depends on nginx. So, I marked the test as skipped, for now.
* DEV: Replace site_setting_saved DiscourseEvent with site_setting_changed
site_setting_saved is confusing for a few reasons:
- It is attached to the after_save of the ActiveRecord model. This is confusing because it only works 'properly' with the db_provider
- It passes the activerecord model as a parameter, which is confusing because you get access to the 'database' version of the setting, rather than the ruby setting. For example, booleans appear as 'y' or 'n' strings.
- When the event is called, the local process cache has not yet been updated. So if you call SiteSetting.setting_name inside the event handler, you will receive the old site setting value
I have deprecated that event, and added a new site_setting_changed event. It passes three parameters:
- Setting name (symbol)
- Old value (in ruby format)
- New value (in ruby format)
It is triggered after the setting has been persisted, and the local process cache has been updated.
This commit also includes a test case which describes the confusing behavior. This can be removed once site_setting_saved is removed.
