Prevent age-restricted fanbox posts from raising errors when source data
is fetched. This prevents error messages from being shown to users when
switching to the edit tab on a post.
This will cause uploads of age-restricted posts to fail with an
unrelated error because we either can't find the image url (if we were
given only the html page) or we can't download the image (because we're
not logged in to Fanbox).
Move html_data_attributes definitions from models to policies. Which
attributes are permitted as data-* attributes is a view level concern
and should be defined on the policy level, not the model level. Models
should be agnostic about how they're used in views.
* Add index on posts.is_deleted. The modqueue was slow because we the
appeal condition wasn't constrained to deleted posts, so it degraded to
a full table scan.
* Avoid extra queries for calculating the page count and disapproval counts.
* Only show the current pending flag on flagged posts. Don't show old flags.
* Don't show both the "This post was flagged for review" and the "This
post was flagged and is pending" notices.
* Only show the current pending appeal in the "This post was appealed"
notice. Don't show old appeals.
* Don't show both the "This post was deleted" and the "This post was
appealed" notice on appealed posts. Only show the "This post was
appealed" notice.
* Show "no reason" if no appeal reason was given.
Fix broken links on various pages:
* The 'History' link in the sidebar on the post index page.
* The 'History' links on the tags index page.
* The 'Tag History' link in the sidebar on the wiki show page.
If a pending post is manually deleted before the 3 day moderation period
is up, then make it cost 5 upload slots until the 3 day period is up.
This means that if a new user uploads 3 bad posts that get manually
deleted, then all of their upload slots will be used and they won't be
able to upload again until 3 days have passed.
* Fix#4552: Multiple quoted search terms not parsed correctly.
* Allow quotes to be escaped in quoted metatags.
* Allow spaces to be escaped in unquoted metatags.
* Allow the empty string to be used in metatags.
Examples:
* `source:""` and `source:''` (same as `source:none`)
* `source:foo\ bar\ baz` (same as `source:"foo bar baz"`)
* `source:"don't say \"lazy\""` (use \" to write a literal ")
* `source:'don\'t say "lazy"'` (use \' to write a literal ')
* `source:"C:\\Windows"` (use \\ to write a literal \)
