If we detect that the session cookie has expired (by the presence of the
`#login_illust` element on the page), then clear the cached session
cookie. The current source fetch will still fail, but the next fetch
will try to login again and hopefully succeed.
Regression caused by the switch from the mobile API to the Ajax API. In
the Ajax API, commentaries have /jump.php?<url> links that we have to strip out.
* fix the test for R18 posts, which are now supported
* replace the dead post for the imageMap test with an active one
* fix the ordering of images: it was possible to get the wrong image in
some cases when not using the batch bookmarklet, because of how fanbox
orders imageMap posts
* fix a bug where the sample wasn't properly replaced with the full
size
* rename test file to match the rest of the other files
Fix the Pixiv API no longer working by rewriting the Pixiv strategy to
use the Ajax API instead of the mobile API.
Before we could authenticate in the mobile API by using the OAuth 2.0
grant_type=password authentication flow. This no longer works. Now it
requires logging in through a HTML page, which is protected by Google
reCaptcha. This makes using the mobile API infeasible.
Instead we switch to the Ajax API, which only needs a PHPSESSID to
authenticate. This can be obtained by logging in manually and using the
devtools to extract the cookie.
This also temporarily removes support for Pixiv novels. This should be
moved to a separate source strategy.
* Fix a broken Twitter profile image upload test.
* Skip a broken DeviantArt flash file upload test (flash no longer
supported by DeviantArt?)
* Skip user upgrade tests when Stripe is not configured.
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).
