The email sending is a crucial flow that should not be interrupted. If
there are database connection issues, we should try to recover from them
automatically by retrying individual database queries and transactions
for a limited amount of time.
This adds a helper method to retry database operations. It limits all
database queries before sending the actual email to maximum 10 minutes.
Database operations that happen after sending have a higher retry time
because they are more crucial to prevent data loss (e.g. saving that an
email was sent).
no issue
When a site doesn't have any emails on boot, it doesn't schedule the email analytics job. With this change, the new email flow will also restart that job after an email has been created.

The flow only send the email to segments that were targeted in the email
content. But if a part of the email is only visible for `status:free`,
that doesn't mean we don't want to send the email to `status:-free`.
This has been corrected in the new email flow.

This change adds a small sleep in between dispatching events in the
worker thread that reads the events from Mailgun. That should reduce the
amount of queries we fire parallel to each other and could cause the
connection pool to run out of connections.
It also reduces the amount of concurrent sending to 2 from 10. Also to
make sure the connection pool doesn't run out of connections while
sending emails, and to reduce the chance of new connections falling back
on a (delayed) replicated database.

We have seen examples of sites with member emails that have invalid characters that can cause an entire email send to fail, or just cause a failure to those addresses. The issue that allowed members with invalid email address to be saved was patched earlier, but its possible there are still sites that contain some of those invalid email addresses.
This change updates new sending service to filter out the recipients with invalid email address before passing them to mail provider, so these rogue addresses don't affect the whole batch in anyway. We also trim the recipient emails to clear out any spaces first, which is the most likely culprit.
- uses new email validator that detects invalid email addresses with special chars
no issue
Tests stopped working because the Mailgun mocker stopped working since we moved to the new email flow.
This also fixes a unit test that needed to get updated.

Adds outbound_link_tagging setting (enabled by default and behind
feature flag). If the feature flag is enabled, and the setting is
disabled, we won't add ?ref to links in emails.
This includes new E2E tests for email click tracking, which were also
extended to check outbound link tagging (for both MEGA and the new email
stability flow).
Also fixes a test fixture for the comments_enabled setting.

- this reverts commit 48dda23554
- also includes a resolution for `@elastic/elasticsearch` so we don't
run a version that is potentially problematic - see referenced issue
for context

A user could use `{uuid}` inside an email only content and it would work. This currently isn't supposed to be used outside internal features (link click tracking, feedback buttons). For now this is only fixed in the new email flow under the email stability flag.

The email service is now fully covered by tests, and this commit also forces the test coverage to remain 100% after future changes.

There was an error when fetching the existing email recipient failure. It ended up matching all recipient failures. The result was that only one failure was stored in the database.

Probem described in issue.
In the old MEGA flow:
- The `email_verification_required` check is now repeated inside the job
In the new email service flow:
- The `email_verification_required` is now checked (didn't happen
before)
- When generating the email batch recipients, we only include members
that were created before the email was created. That way it is
impossible to avoid limit checks by inserting new members between
creating an email and sending an email.
- We don't need to repeat the check inside the job because of the above
changes
Improved handling of large imports:
- When checking `email_verification_required`, we now also check if the
import threshold is reached (a new method is introduced in
vertificationTrigger specifically for this usage). If it is, we start
the verification progress. This is required for long running imports
that only check the verification threshold at the very end.
- This change increases the concurrency of fastq to 3 (refs
https://ghost.slack.com/archives/C02G9E68C/p1670232405014209). So when
running a long import, it is now possible to send emails without having
to wait for the import. Above change makes sure it is not possible to
get around the verification limits.
Refactoring:
- Removed the need to use `updateVerificationTrigger` by making
thresholds getters instead of fixed variables.
- Improved awaiting of members import job in regression test
- this was all getting terribly behind so I've done several things:
- majority of `@tryghost/*` except Lexical packages
- gscan + knex-migrator to remove old `@tryghost/errors` usage
- bumped lockfile

The preview text is getting set to subject line in the new email flow so it repeats multiple times in the inbox(subject+preview+title). This was because the new flow doesn't use the post serialisation that the old system did, causing excerpt to be empty in the email rendering.
Old system was using post serialisation here -
a721e4f2d7/ghost/core/core/server/services/mega/post-email-serializer.js (L136-L139).
This change adds explicit method to calculate the preview text for email in email renderer service using same logic as used in old system.

- Removed the usage of the `isLocalContentImage` Koenig util for the
email header and feature image url generation.
- While we were trying to set the width to 1200px, we didn't have that
size hardcoded. So that url would redirect back to the original location
instead of serving a smaller image. So I added a new internal size to
the `imageOptimization` config.
- This is fixed in both the new and old email flow and includes some
extra tests for the new flow.

When a member is deleted, and we receive an opened event for an email to
that member. We threw an uncaught Bookshelf EmptyResponse error.
- This change makes fetching the member not a requirement when handling
that event in the last seen at updater.
- It also adds try catches for all event listeners in the last seen at
updater

- Includes a new pattern in the job manager that allows us to properly
await jobs.
- Added new convenience mocking methods to stub settings
- Tests the main flows for bulk sending:
- Sending in multiple batches
- Sending to multiple segments
- Handling a failed batch and retrying that batch
- Fixes bug in batch generation (ordering not working)
In a different PR I'll add more detailed tests.

Saves events in the database and collects error information.
Do note that we can emit the same events multiple times, and as a result
out of order. That means we should correctly handle that a delivered
event might be fired after a permanent failure. So a delivered event is
ignored if the email is already marked as failed. Also delivered_at is
reset to null when we receive a permanent failure.

- adds new mailgun provider to send out batch emails
- updates sending service to send email id for mailgun provider, allows tagging mail with email id
fixes https://github.com/TryGhost/Team/issues/2308
- Still has some missing pieces, but mostly works.
- Uses new handlebars template for emails
- When sending emails with the new email stability flag enabled, one
test email is now sent via the default smtp ghost mailer.

This moves the processing of the events from the event-processor to a
new email-event-processor in the email-service package.
- The `EmailEventProcessor` only translates events from
providerId/emailId to their known emailId, memberId and recipientId, and
dispatches the corresponding events.
- Since `EmailEventProcessor` runs in a separate worker thread, we can't
listen for the dispatched events on the main thread. To accomplish this
communication, the events dispatched from the `EmailEventProcessor`
class are 'posted' via the postMessage method and redispatched on the
main thread.
- A new `EmailEventStorage` class reacts to the email events and stores
it in the database. This code mostly corresponds to the (now deleted)
subclass of the old `EmailEventProcessor`
- Updating a members last_seen_at timestamp has moved to the
lastSeenAtUpdater.
- Email events no longer store `ObjectID` because these are not
encodable across threads via postMessage
- Includes new E2E tests that test the storage of all supported Mailgun
events. Note that in these tests we run the processing on the main
thread instead of on a separate thread (couldn't do this because
stubbing is not possible across threads)
There are some missing pieces that will get added in later PRs (this PR
focuses on porting the existing functionality):
- Handling temporary failures/bounces
- Capturing the error messages of bounce events

New batch sending flow (still WIP). Logs the sent emails instead of actually sending them. Unit tests are coming in later commits.
fixes https://github.com/TryGhost/Team/issues/2282
Added a new email service package that is used when the email stability
flag is enabled. Currently not yet implemented so will throw an error
for all entry points (if flag enabled).
Removed usage of `labs.isSet.bind` across the code, because that breaks
the stubbing of labs by `mockManager.mockLabsEnabled` and
`mockManager.mockLabsDisabled`. `flag => labs.isSet(flag)` should be
used instead.
All email depending tests now disable the `emailStability` feature flag
to keep the tests passing + make sure we still run all the tests for the
old flow while the email stability package is being built.
