- added two default aggregations for overall email count and opened email count
- when number of tracked emails is sufficient add the open rate aggregation to the update query
refs https://github.com/TryGhost/Ghost/issues/12461
- adds `members.email_count` and `members.email_opened_count` columns to contain cached counts for faster queries when outputting member data via API
- adds migration to populate cached counts with existing data
- tested locally on ~50k members which took ~4sec on mysql
- updates members output serializer to include the new fields in API output
refs https://github.com/TryGhost/Ghost/issues/12421
- add `orderRawQuery` function to members model so that we can ensure members with an open rate are ordered before members without an open rate no matter the order direction chosen
- added `email_open_rate` to members in the test fixtures to allow testing of order

requires https://github.com/TryGhost/Ghost/pull/12457
- updates stats aggregator to calculate and store an open rate for each member
- uses two queries because I couldn't find a reasonable approach to perform the update in a single query as per the email aggregation
- benchmarked locally at <1sec/1000members
- will not store an open rate unless the number of tracked emails sent to a member is above a certain threshold (defaults to 5) to avoid new members being heavily weighted
- fixes typo in EmailAnalytics that was stopping member stats from being aggregated
refs https://github.com/TryGhost/Ghost/issues/12421
- nullable so we can distinguish between members that have and haven't received any trackable emails
- indexed because we'll be using this column for sorting
no issue
- fixed usage of rewire and sinon spies
- spies actually set (and reset) on the rewired module so the spies are called in place of the original functions
- fixed should syntax for spies, they were written with chai syntax but we don't use chai in server-side code
- chained `.catch(done)` to the `.catch(assertions)` in tests that are testing errors so that we don't have unhandled rejections and 60s timeouts when an assert fails
- changed `.gif` to `.ico` to match current fetch-only extension list
- fixed "[failure] can handle an error with statuscode not 200 (image-size)" which was expecting the `sizeOf` function to be called when it shouldn't be called
- `https` was getting caught somewhere with nock and metascraper and
caused each test case to hang for 3 seconds
- `http` still tests what we want and is instant
refs https://github.com/TryGhost/Ghost/issues/12420
- updated `order` bookshelf plugin's `parseOrderOption()` method to return multiple order-related properties
- `order` same as before, a key-value object of property-direction
- `orderRaw` new property that is a raw SQL order string generated from `orderRawQuery()` method in models
- `eagerLoad` new property that is an array of properties the `eagerLoad` plugin should use to join across
- updated `pagination.fetchAll()` to apply normal order + raw order if both are available and to handle eager loading / joins when `options.eagerLoad` is populated
- updated post model to include details for email relationship and to add `orderRawQuery()` that allows `email.open_rate` to be used as an order option
- refactoring the acceptance tests to use async-await removes all the Promise
chaining we had, and streamlines the coding styles we have across the code so
test files are more alike
- at the time of writing, the v3 API === canary API
- we have both v3 + canary regression tests, which are nearly the same
but there are slight deviations that we keep missing when adding new
tests
- the canary tests are actually describing functionality of the v3 API
- therefore, we should be ok to delete the v3 regression tests for now
- when v3 is stable, we can copy the canary tests back to v3
no issue
- job registration was checking for submitted emails in it's email count but the job registration method is called as soon as an email is created meaning the email has a status of 'pending' which prevented the analytics job from being started until a second email was sent
no issue
- email analytics may be desirable to fully switch off in certain circumstances, when that happens we want to prevent related background jobs from running and expose the feature flag via the config endpoint in the Admin API so that clients can adjust accordingly
no issue
- if emails are older than 30 days we wouldn't be able to fetch any analytics for them and if a site used emails in the past but is no longer using them it doesn't make sense to keep potentially expensive background worker threads spinning up
no issue
- recurring jobs spin up worker threads which can be quite CPU intensive even when not performing much processing, this can be problematic in environments where there are many Ghost instances running
- updated the email job scheduling to be skipped on bootup when there are no emails in the database and to be started when the first email is created as long as we're not in testing env
- increase analytics job schedule from every 2 minutes to every 5 minutes to help spread the load further across instances
no issue
- typically cron/later schedules will schedule for :00 on the minute which would create API spikes with every members-email-using Ghost site hitting the API at the same time
- adjusted the scheduling to use cron syntax with job runs every 2 minutes on 1,3,5... or 2,4,6... and a random seconds value to smooth usage across sites
