Add partial support for fetching videos from ArtStation posts that
contain videos. Most of this code is disabled for now because actually
downloading these videos requires bypassing a Cloudflare captcha.
Support grabbing the full image for Tinami uploads, rather than the sample.
Getting the full image requires making a request like this:
curl -X POST \
-H 'Referer: https://www.tinami.com/' \
-H 'Content-Type: application/x-www-form-urlencoded' \
-H 'Cookie: Tinami2SESSID=<redacted>;' \
--data-raw 'action_view_original=true&cont_id=1087268ðna_csrf=<redacted>' \
https://www.tinami.com/view/1087268
Then scraping the <img> tag from the resulting HTML page.
If the post has multiple images, then we need to scrape and pass the
`sub_id` of the image too.
Fixes#2818.
Fix the artist finder returning incorrect results when given a nil URL.
This only happened when an artist with a URL like this existed:
http:///blog.naver.com/dan_rak
Note the triple `///`; the extra `/` messed up the artist finder.
The artist finder may be given a nil URL when a source strategy returns
a nil profile URL, usually because the source is bad_id.
Change how artist URLs are normalized in artist entries. Don't try to secretly
convert image URLs to profile URLs in artist entries. For example, if someone puts a
Pixiv image URL in an artist entry, don't secretly try to fetch the source and
convert it into a profile URL in the `normalized_url` field.
We did this because years ago, it was standard practice to put image URLs in artist
entries. Pixiv image URLs used to contain the artist's username, so we used to put
image URLs in artist entries for artist finding purposes. But Pixiv changed it so
that image URLs no longer contained the username, so we dealt with it by adding a
`normalized_url` column to artist_urls and secretly converting image URLs to profile
URLs in this field. But this is no longer necessary because now we don't normally put
image URLs in artist entries in the first place.
Now the `profile_url` method in `Source::URL` is used to normalize URLs in artist
entries. This lets us parse various profile URL formats and normalize them into a
single canonical form.
This also removes the `normalize_for_artist_finder` method from source strategies.
Instead the `profile_url` method is used for artist finding purposes. So the profile
URL returned by the source strategy needs to be the same as the URL in the artist
entry in order for artist finding to work.
Add a method for converting a source URL into a profile URL. This will
be used for normalizing profile URLs in artist entries.
Also add the ability to parse a few more profile URL formats.
This turns out to be a little simpler than keeping them separate. The
only thing special we have to do for Sta.sh is use the Sta.sh page when
we have a DeviantArt image with a Sta.sh referer.
Bug: We assumed the referer URL was from the same site as the target
URL. We tried to call methods on the referer only supported by the
target URL.
Fix: Ignore the referer URL when it's from a different site than the
target URL.
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.
Fix `image_urls` returning `[nil]` when fetching data for a image URL
that was bad_id. In that case `original_urls` is empty, so we fall back
to using the deleted image URL as-is.
* Fix error when uploading non-ugoira files.
* Fix sample image URLs not being rewritten to full images correctly. We
have to get the full image URL from the API because given an
/img-master/ URL, we don't know what the original file extension is.
* Drop support for preview_urls. This means that IQDB lookups may be
slower, especially for ugoiras, since we have to download the full
ugoira now. However, ugoira lookups should produce better results,
since the ugoira thumbnail chosen by Pixiv wasn't necessarily the same
as the thumbnail chosen by Danbooru.
* Drop support for uploading single manga pages:
http://www.pixiv.net/member_illust.php?mode=manga_big&illust_id=18557054&page=2
Previously uploading an URL like this would only upload a single image
out of a multi-image work. Now it will upload all images in the work.
Pixiv no longer supports URLs like this, so we don't either.
* Add support for parsing URLs like this:
https://i.pximg.net/c/360x360_70/custom-thumb/img/2022/03/08/00/00/56/96755248_p0_custom1200.jpg
Apparently artists can choose a custom thumbnail now (not like anyone
will try to upload one though).
Add upload support for Pixiv Sketch. Fetch tags, commentary, and artist,
and rewrite sample images to full images.
Authentication isn't required. R18 images are hidden in the browser but
visible in the API.
Additionally, fixed some broken tests and changed normalization for urls
of album type to point to the mobile version instead, because they're
only visible to logged-in users.
Also fixes the uploader uploading all images when trying to upload only a
single image in a multi-image work. Caused by `image_urls` incorrectly
returning all images when the source strategy was given a url for a
single image.
Introduce a Source::URL class for parsing URLs from source sites. Refactor the Twitter
source strategy to use it.
This is the first step towards factoring all the URL parsing logic out of source
strategies and moving it to subclasses of Source::URL. Each site will have a subclass
of Source::URL dedicated to parsing URLs from that site. Source strategies will use
these classes to extract information from URLs.
This is to simplify source strategies. Most sites have many different URL formats we have
to parse or rewrite, and handling all these different cases tends to make source
strategies very complex. Isolating the URL parsing logic from the site scraping logic
should make source strategies easier to maintain.
NicoSeiga changed it so that on every login, you must enter a 2FA code
sent by email. This broke the NicoSeiga strategy. The fix is to just use
a static session cookie instead (and hope it doesn't expire, and isn't
tied to an IP).
The `nico_seiga_login` and `nico_seiga_password` config settings have
been removed from config/danbooru_default_config.rb and replaced by
`nico_seiga_user_session`. If you run your own Danbooru instance, you
will have to update your config file manually.
Introduce a Danbooru::URL class for dealing with URLs. This is a wrapper
around Addressable::URI that adds some additional helper methods. Most
significantly, the `parse` method only allows valid http/https URLs, and
it returns nil instead of raising an exception when the URL is invalid.
