The analytics page showed non-unique counts for views and clicks which
was misleading and source of confusion: #522, #561, #571, #676, #680
This commit changes this behaviour to pull unique views and clicks when
individual subscriber tracking is turned on in settings, and non-unique
counts when it is turned off (as `subscriber_id` in `campaign_views`
and `link_clicks` will be NULL, rendering unique queries dysfunctional).
This commit changes the stats SQL queries to use string interpolation
to either to SELECT `*` or `DISTINCT subscriber_id` on app boot based
on the setting in the DB. This involves significant changes to how
queries are read and prepared on init.
- Refactor `initQueries()` to `readQueries()` and `prepareQueries()`.
- Read queries first before preparing.
- Load settings from the DB using the read settings query.
- Prepare queries next. Use the privacy setting from the DB to apply
string interpolation to the analytics queries to pull
unique/non-unique before preparing the queries.
On the UI:
- Show a note on the analytics page about unique/non-unique counts.
- Hide the % donut charts on the analytics page in non-unique mode.
Closes#676, closes#680
- Add indexes.
- Refactor dashboard charts and view/click count queries.
(~10x speed bump on a setup of 7mn subscribers and 80mn views)
- Refactor get subscriber queries.
(~10x speed bump on 7mn subscribers)
- Make subscriber UI issue an equality query for email seach strings.
- Blocklist or unsubscribe subscribers based on a bounce threshold
- Add /bounces UI for viewing bounces and in the subscriber view
- Add settings UI for managing bounce settings
- Add support for scanning POP3 bounce mailboxes
- Add a generic webhook for posting custom bounces at /webhooks/bounce
- Add SES bounce webhook support at /webhooks/services/ses
- Add Sendgrid bounce webhook support at /webhooks/services/sendgrid
In addition to generating HTML forms for selected public lists,
the form page now shows a URL (/subscription/form) that can be
publicly shared to solicit subscriptions. The page lists all
public lists in the database. This page can be disabled on the
Settings UI.
- Configures `max_open` and `max_idle` in default configs to `25`.
This changes the previous behaviour of connection pooling where both the
values were unset (from default config) and causes unbounded connection
limit and no connection reuse.
- Configures `db.SetConnMaxLifetime` which sets the maximum time the
connection can be reused in a pool.
- Sets `max_conn_lifetime` in default config as `5 minutes`.
Closes https://github.com/knadh/listmonk/issues/225
Lists, campaigns, and subscribers tables now support server-side
sorting from the UI. This significantly changes the internal
queries from prepared to string interpolated to support dynamic
sort params.
