* Automatically fix all tags with incorrect counts during daily
maintenance (previously only tags with negative counts were fixed).
* Log fixed tags to NewRelic.
* Remove the ability to manually fix tag counts with the "Fix" button on
the /tags listing. This is no longer necessary now that tags are
fixed automatically.
`User.find_by_name` used `where_ilike` to do a case-insensitve name
search, but it didn't escape `*` or `\` characters first, so it didn't
handle names containing these characters properly.
* Always display 'Saved searches' link in subnav bar, even if the user
hasn't created any saved searches yet.
* Eliminate use of `has_saved_searches` bitpref on users.
* Only check for conflicts with existing aliases/implications when
requests are created or approved, not when requests are rejected.
* Use `update!(status: "deleted")` instead of `update(status: "deleted")`
so that if rejecting the request fails we fail immediately instead of
continuing on and updating the forum topic.
* Wrap `reject!` and `TagChangeRequestPruner.reject_expired` in
transactions so that if updating either the request or the forum
fails, they both get rolled back.
Use git clean to delete stale files from an earlier checkout. These
files interfered with various things (specifically, a comment vote test
failed because there was an old comment_votes/create.json.erb template
hanging around that changed the behavior of the POST /comment_votes endpoint).
Stop maintaining pool category pseudo tags (pool:series, pool:collection)
in pool strings. They're no longer used and the changes to the
`Post#pools` method in dc4d2e54b caused issues with this.
Also allow Members to change the category of large pools again. This was
only restricted because maintaining these pseudotags forced us to update
every post in the pool whenever a pool's category was changed.
Replace the `method_attributes` and `hidden_attributes` methods with
`api_attributes`. `api_attributes` can be used as a class macro:
# include only the given attributes.
api_attributes :id, :created_at, :creator_name, ...
# include all default attributes plus the `creator_name` method.
api_attributes including: [:creator_name]
or as an instance method:
def api_attributes
[:id, :created_at, :creator_name, ...]
end
By default, all attributes are included except for IP addresses and
tsvector columns.
In xml responses, if the result is an empty array we want the response
to look like this:
<posts type="array"/>
not like this (the default):
<nil-classes type="array"/>
This refactors controllers so that this is done automatically instead of
having to manually call `@things.to_xml(root: "things")` everywhere. We
do this by overriding the behavior of `respond_with` in `ApplicationResponder`
to set the `root` option by default in xml responses.
Stop using the pool_string field internally, but keep maintaining it
until we can drop it later.
* Stop using the pool_string for `pool:<name>` metatag searches.
* Stop using the pool_string in the `Post#pools` method. This is used to
get the list of pools on post show pages.
Revert optimization from a6163258b. Turns out that we have to resolve
aliases in fast_count, otherwise for aliased tags we'll return an empty
count.
Fixes#4156.
Don't try delete files belonging to completed uploads during pruning. If
an uploaded post was replaced shortly after upload, then the original
file could get deleted during pruning since it's no longer in use, but
this isn't supposed to happen until the replacement grace period (30
days) is over.
* Don't try to call `sadd` when a search returns no results (`sadd`
fails in this case).
* Add a timeout when populating the search.
* Don't offload the search to read replica. The main db is fine.
* Disable synchronous population of searches. This was too slow.
* Change the source index on posts from `(lower(source) gin_trgm_ops) WHERE source != ''`
to just `(source gin_trgm_ops)`. The WHERE clause prevented the index
from being used in source:<url> searches because we didn't specify
the `source != ''` clause in the search itself. Excluding blank
sources only saved a marginal amount of space anyway. This fixes
timeouts in source:<url> searches and in the bookmarklet (since we do
a source dupe check on the upload page too).
* Also switch from indexing `lower(name)` to `name` on pools and users.
We don't need to lowercase the column because GIN indexes can be used
with both LIKE and ILIKE queries.
Make /favorites redirect to a ordfav:<user> search instead of having a
separate view just for favorites. This duplicated a lot of code for no
good reason.
Comments have three states: visible, hidden, and invisible. Visible
comments are always shown. Hidden comments are not shown until the user
clicks 'Show all comments'. Invisible comments are never shown to the
user. Deleted comments are treated as hidden for moderators and
invisible for normal users. Thresholded comments are treated as hidden
for all users.
Rewrite the implementation of related tags to be simpler, faster, and
more accurate:
* The related tags are now calculated by taking a random sample of 1000
posts, finding the top 250 most frequent tags among those posts, then
ordering those tags by cosine similarity.
* Related tags can generally be calculated in 50-300ms at these sample
sizes. Very high sample sizes (25000+ posts) are still relatively fast
(1-3 seconds), but generally they don't improve accuracy much.
* Related tags are now cached in redis rather than in the tags table.
The related_tags column in the tags table is no longer used.
* Only the related tags in the search taglist are cached. The related
tags returned by the 'Related tags' button are not cached.
* The cache lifetime is a fixed 4 hours.
* The 'Related tags' button now works with metatags.
* The /related_tag page now works with metatags and multitag searches.
Fixes#4134, #4146.
* Drop support for `source:pixiv/artist-name` searches. This was a hack
that only worked on old pixiv urls that haven't been used for years.
* Replace the old SourcePattern(lower(source)) index with a trigram index.
