Fixes an exception when attempting to upload a Pixiv image from a
deleted work. The download strategy tries to fetch the source data in
the course of rewriting the URL, which fails if the work has been
deleted from Pixiv.
Raise a BadIDError and leave the URL as-is (don't rewrite it).
Fixes an "incompatible character encodings: UTF-8 and ASCII-8BIT"
exception when uploading a deleted Pixiv post.
Caused by the Pixiv API error message not having the encoding set to UTF-8.
Fixup for a bug in 134958d1. `Post.fast_count("pool:1537")` still
returned zero because `Tag.is_simple_tag?` incorrectly parsed
"pool:1537" as a simple tag, so Post.fast_count still looked for it in
the tags table and found the empty "pool:1537" tag.
Fixes Post#get_count_from_cache to only lookup the count in the tags
table when the search is for a single "simple" tag.
Check memcache when the search is not a simple tag:
* multi-tag searches (touhou rating:s)
* single metatag searches (rating:s, source:"foo bar")
* negated tags (-touhou)
* wildcard tags (*touhou*)
* or searches (~touhou)
Purges gentags with invalid names from the tags table. Addresses #3390
(Searching certain metatags results in an empty paginator) by removing
metatags from the tags table.
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.
Due to missing || operators, for Pawoo/Tumblr/Artstation uploads the
source wasn't changed from the direct image URL to the html page URL
after upload.
Fixes an `undefined method `gsub' for nil:NilClass` exception when fetching source
data for this url:
* /uploads/new?url=https%3A%2F%2Fuiti-ukumo.tumblr.com%2Fpost%2F156157443158%2F2016-12
Bug introduced in 3c524aa5: `url` wasn't initialized due to `@url = url`
being removed from Sources::Site#initialize.
