Refactor source strategies to remove the `canonical_url` method.
`canonical_url` returned the URL that should be used as the source of
the post after upload. Now we simply use `Source::URL#page_url` to
determine the source after upload. If the source is an image URL that is
convertible to a page URL, then the image URL is used as the source. If
the source is an image URL that is not convertible to a page URL, then
the page URL is used as the source.
This simplifies source strategies so that all they have to care about is
implementing the `Source::URL#page_url` and `Sources::Strategies#page_url`
methods, and the preferred source will be chosen for posts automatically.
Remove the `preview_urls` method from strategies. The only place this was used was
when doing IQDB searches, to download the thumbnail image from the source instead of
the full image.
This wasn't worth it for a few reasons:
* Thumbnails on other sites are sometimes not the size we want, which could affect
IQDB results.
* Grabbing thumbnails is complex for some sites. You can't always just rewrite the
image URL. Sometimes it requires extra API calls, which can be slower than just
grabbing the full image.
* For videos and animations, thumbnails from other sites don't always match our
thumbnails. We do smart thumbnail generation to try to avoid blank thumbnails, which
means we don't always pick the first frame, which could affect IQDB results.
API changes:
* /iqdb_queries?search[file_url] now downloads the URL as is without any modification.
Before it tried to change thumbnail and sample size image URLs to the full version.
* /iqdb_queries?search[url] now returns an error if the URL is for a HTML page that
contains multiple images. Before it would grab only the first image and silently
ignore the rest.
Remove the `image_url` method from source strategies. This method would
return only the first image if a source had multiple images. The
`image_urls` method should be used instead. Tests were the main place
that still used `image_url` instead of `image_urls`.
Also make post replacements return an error if replacing with a source
that contains multiple images, instead of just blindly replacing the
post with the first image in the source.
* Move the source normalization logic out of the post model
and into individual sources' strategies.
* Rewrite normalization tests to be handled into each source's test,
and expand them significantly. Previously we were only testing
a very small subset of domains and variants.
* Fix up normalization for several sites.
* Normalize fav.me urls into normal deviantart urls.
* Normalize spaces to underscores when saving other names. Preserve case
since case can be significant.
* Fix WikiPage#other_names_include to search case-insensitively (note:
this prevents using the index).
* Fix sources to return the raw tags in `#tags` and the normalized tags
in `#normalized_tags`. The normalized tags are the tags that will be
matched against other names.
Derive the artist name / profile url / page url from the source URLs when
the API response is unavailable because the Tumblr post was deleted.
This fixes the artist finder to work on bad_tumblr_id posts.
Fail loudly if we forget to whitelist a param instead of silently
ignoring it.
misc models: convert to strong params.
artist commentaries: convert to strong params.
* Disallow changing or setting post_id to a nonexistent post.
artists: convert to strong params.
* Disallow setting `is_banned` in create/update actions. Changing it
this way instead of with the ban/unban actions would leave the artist in
a partially banned state.
bans: convert to strong params.
* Disallow changing the user_id after the ban has been created.
comments: convert to strong params.
favorite groups: convert to strong params.
news updates: convert to strong params.
post appeals: convert to strong params.
post flags: convert to strong params.
* Disallow users from setting the `is_deleted` / `is_resolved` flags.
ip bans: convert to strong params.
user feedbacks: convert to strong params.
* Disallow users from setting `disable_dmail_notification` when creating feedbacks.
* Disallow changing the user_id after the feedback has been created.
notes: convert to strong params.
wiki pages: convert to strong params.
* Also fix non-Builders being able to delete wiki pages.
saved searches: convert to strong params.
pools: convert to strong params.
* Disallow setting `post_count` or `is_deleted` in create/update actions.
janitor trials: convert to strong params.
post disapprovals: convert to strong params.
* Factor out quick-mod bar to shared partial.
* Fix quick-mod bar to use `Post#is_approvable?` to determine visibility
of Approve button.
dmail filters: convert to strong params.
password resets: convert to strong params.
user name change requests: convert to strong params.
posts: convert to strong params.
users: convert to strong params.
* Disallow setting password_hash, last_logged_in_at, last_forum_read_at,
has_mail, and dmail_filter_attributes[user_id].
* Remove initialize_default_image_size (dead code).
uploads: convert to strong params.
* Remove `initialize_status` because status already defaults to pending
in the database.
tag aliases/implications: convert to strong params.
tags: convert to strong params.
forum posts: convert to strong params.
* Disallow changing the topic_id after creating the post.
* Disallow setting is_deleted (destroy/undelete actions should be used instead).
* Remove is_sticky / is_locked (nonexistent attributes).
forum topics: convert to strong params.
* merges https://github.com/evazion/danbooru/tree/wip-rails-5.1
* lock pg gem to 0.21 (1.0.0 is incompatible with rails 5.1.4)
* switch to factorybot and change all references

Fixes a bug from 9a3824a. When an artist entry is saved, `ArtistUrl.normalize`
is called on every URL, which calls `Sources::Site.new(url)`. This
raised NoStrategyError when an artist entry contained URLs that weren't
recognized by any strategy.
This also caused `Fetch source data` to fail in certain cases when it
attempted to find the artist.
* Convert Tumblr commentary to DText.
* Strip extraneous whitespace in links and blockquotes.
* Add newlines after block elements to ensure they're separated from
subsequent blocks.
