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.
Make all edit forms show warnings in addition to errors. Also render
warnings and errors using DText.
Currently this only affects artists and wiki pages because they're the
only pages that have warnings.
Show a warning when creating a duplicate artist; that is, when adding a
URL that already belongs to another artist.
This is a soft warning rather than a hard error because there are some
cases where multiple artists legitimately share the same site or account.
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.
Make the artist finder search for artists using the `url` field instead
of the `normalized_url` field. This lets us get rid of `normalized_url`
in the future.
As described in 10dac3ee5, artist URLs have both a `url` column and a
`normalized_url` column. The `normalized_url` column was the one used
for artist finding. The `url` was secretly normalized behind the scenes
so that artist finding would work no matter how the URL was written in
the artist entry. This is no longer necessary now that URLs are directly
normalized in artist entries.
This fixes various cases where artist finding didn't work for non-obvious
reasons, usually because the URL wasn't written in the right format so
it wasn't properly normalized behind the scenes.
This also makes it so that artist finding is case-insensitive, which
fixes#4821. Hopefully no sites are perverse enough to allow two
different usernames that differ only in case.
Users running their own Danbooru instance may have to fix the URLs in
their artist entries for artist finding to work again. There are a few
fix scripts to help with this:
* script/fixes/104_normalize_weibo_artist_urls.rb
* script/fixes/105_normalize_pixiv_artist_urls.rb
* script/fixes/106_normalize_artist_urls.rb
mangaupdates, nijie, sakura-ne-jp: replaced with higher resolution,
the old icons look blurry on hidpi screens.
skeb, tumblr: replaced with transparent versions.
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.
