Post.fast_count is dependent on the current user's settings. This meant
that tag counts in wiki pages could be different from the tag counts
displayed in tag lists.
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.
