Add methods to Source::URL for determining whether a URL is an image
URL, a page URL, or a profile URL.
Also add more source URL tests and fix various URL parsing bugs.
Fix the page_url method not to return URLs like this:
https://seiga.nicovideo.jp/image/source/8017978 (page: https://seiga.nicovideo.jp/watch/mg310193)
These are direct image URLs, not page URLs. It's not generally possible
to get to the page URL from an image URL like this.
This fixes it so that we don't incorrectly set the source of NicoSeiga
uploads to the image URL.
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 `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 uploads for NicoSeiga sources not working because the strategy
returned URLs like the one below in the list of image_urls, which
require a login to download:
https://seiga.nicovideo.jp/image/source/10315315
Also fix certain URLs like https://dic.nicovideo.jp/oekaki/52833.png not
working, because they didn't contain an image ID and the image_urls
method returned an empty list in this case.
Fix the test suite failing when trying to run it in the default state
with no config file or API keys configured. Most source sites require
API keys or login credentials to be set in order to work. Skip these
tests when credentials aren't configured.
* Get rid of mechanize, fully switch to Danbooru::Http
* Switch to mobile api, improving speed
* Merge main and manga clients
* Add full support for manga pages
* Add support for anonymous and r-15 images
* Don't fail when attempting to upload oekaki direct links
* Various misc fixes
* 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.
* `summary` is the wrong field. It's the list of comments left by users,
not the artist's commentary.
* For some reason `doc.response.image.description` returns nil even
though the description element exists. Switch to `Hash.from_xml` to
avoid this.
