This reduces chances of errors where consumers of strings mutate inputs
and reduces memory usage of the app.
Test suite passes now, but there may be some stuff left, so we will run
a few sites on a branch prior to merging
Introduce new patterns for direct sql that are safe and fast.
MiniSql is not prone to memory bloat that can happen with direct PG usage.
It also has an extremely fast materializer and very a convenient API
- DB.exec(sql, *params) => runs sql returns row count
- DB.query(sql, *params) => runs sql returns usable objects (not a hash)
- DB.query_hash(sql, *params) => runs sql returns an array of hashes
- DB.query_single(sql, *params) => runs sql and returns a flat one dimensional array
- DB.build(sql) => returns a sql builder

This updates tests to use latest rails 5 practice
and updates ALL dependencies that could be updated
Performance testing shows that performance has not regressed
if anything it is marginally faster now.
* title info under notification
* create badge-title as component
* display available titles, close button
* remove visual feedback when grant new badge
* Made changes after review.
* Some minor fixes.
Upon saving a badge or requesting a badge result preview,
BadgeGranter.contract_checks! will examine the provided badge SQL for
some contractual obligations - namely, the returned columns and use of
trigger parameters.
Saving the badge is wrapped in a transaction to make this easier, by
raising ActiveRecord::Rollback on a detected violation.
On the client, a modal view is added for the badge query sample run
results, named admin-badge-preview.
The preview action is moved up to the route.
The save action, on failure, triggers a 'saveError' action (also in the
route).
The preview action gains a new parameter, 'explain', which will give the
output of an EXPLAIN query for the badge sql, which can be used by forum
admins to estimate the cost of their badge queries.
The preview link is replaced by two links, one which omits (false) and
includes (true) the EXPLAIN query.
The Badge.save() method is amended to propogate errors.
Badge::Trigger gets some utility methods for use in the
BadgeGranter.contract_checks! method.
Additionally, extra checks outside of BadgeGranter.contract_checks! are
added in the preview() method, to cover cases of null granted_at
columns.
An uninitialized variable path is removed in the backfill() method.
TODO - it would be nice to be able to get the actual names of all
columns the provided query returns, so we could give more errors
This is tricky and optional, some badges are very expensive to calculate
pass in :backfill , :post_ids and :user_ids to all badge queries so they
can do pre-filtering, if you do it after the sub-query it is too late
Introduced badge triggers, introduced concept of badge that happens due to a post but has the post hidden
Delta badge grant happens once a minute, backed by redis
